Description

Communication system

Technical Field

The present application relates to the field of electronic products, and in particular, to a communication system.

Background

A conventional communication system includes a display device and an input device. The display device and the input device are connected to each other by a connection mechanism. However, since the conventional connection mechanism is often protruded outside the housing of the display device or the input device, not only is the display device or the housing of the input device not attractive in appearance due to the abrupt protrusion, but also the protruded portion is vulnerable to impact by other objects in terms of structure, resulting in a short structural life.

In a first aspect, an embodiment of the present application provides a communication system. The communication system includes a display device and an input device.

The display device comprises a first shell and a bolt, wherein the first shell is provided with a through hole, the through hole is communicated with the inside and the outside of the first shell, and at least part of the bolt is arranged in the first shell. The input device is provided with an inserting space, the inserting space comprises a first space and a second space, the second space is communicated with the first space, and the second space is located on the periphery of the first space.

When the display device is close to the input device, a part of the bolt extends out of the through hole along the first direction and is inserted into the first space, and then is clamped into the second space along the second direction, and the second direction is different from the first direction.

It will be appreciated that the latch is protected by the first housing by locating at least part of the latch within the first housing. Thus, the bolt is not easy to damage, the service life of the structure is longer, the structure of the communication system is also not easy to damage, and the service life of the structure is longer.

In addition, through setting up the bolt in the inside of first casing, can leave sufficient space for the inside of input device's second casing, the space of leaving like this can be used for setting up pivot mechanism to make when display device and input device are connected, display device can also rotate through pivot mechanism relative input device, in order to adjust the angle of display device relative input device.

In addition, a part of the bolt can be inserted into a first space of the plug-in space along a first direction and then clamped into a second space of the plug-in space along a second direction. At this time, a part of the plug pin can be clamped on the clamping surface of the plugging space. In this way, the display device can be stably connected to the input device. Therefore, the display device and the input device of the embodiment not only can realize plugging, but also can ensure that the display device is not easy to separate from the input device after plugging, and the stability of a communication system is better.

In one possible implementation manner, the display device includes a lever and a first magnetic group, the lever includes a first rod portion and a rotating portion, the rotating portion is connected to the first rod portion, the first rod portion is connected to the latch in a sliding manner, the rotating portion rotates relative to the first housing, and the first magnetic group is fixed on the first rod portion; the input device comprises a third magnetic group, and the third magnetic group is fixed on the second shell.

The first rod part drives a part of the bolt to be inserted into the first space along the first direction under the attractive force of the first magnetic group and the third magnetic group.

It should be noted that, the rotation of the rotating portion relative to the first housing includes the following two cases: one is that the rotating part is directly connected with the first shell in a rotating way. The other is that a fixed plate is fixed on the first shell, and the rotating part is rotationally connected with the fixed plate.

It can be understood that the lever structure is provided, and the attractive force of the first magnetic group and the third magnetic group is utilized to drive a part of the bolt to be inserted into the first space along the first direction. The structure is simple, and the occupied internal space of the first shell is less. In other possible implementations, a portion of the latch may be driven by a motor or other driving mechanism to insert into the first space in the first direction.

In one possible implementation, the lever includes a second rod portion connected to a side of the rotating portion remote from the first rod portion. The display device comprises a torsion spring arranged on the first shell, and the torsion spring is used for applying force along the first direction to the second rod part. Thus, when the first lever portion receives a force in the first direction, the first lever portion of the lever may rotate in the counterclockwise direction under the elastic force of the torsion spring. At this time, the first rod portion of the lever can drive a part of the latch to slide out of the first space of the plugging space.

It can be understood that by the structure of the second rod portion of the lever and the torsion spring applying a force along the first direction to the second rod portion, a part of the latch is driven to slide out of the first space of the plugging space by the first rod portion of the lever. The structure is simple, and the occupied internal space of the first shell is less. In other possible embodiments, a part of the plug pin can also be slid out of the first space of the plug space by means of a motor or other drive mechanism.

In one possible implementation, the display device further includes a second magnetic group, the second magnetic group being fixed on the second rod portion; the input device comprises a fourth magnetic group which is fixed on the second shell; when the display device is close to the input device, the second magnetic group and the fourth magnetic group generate repulsive force.

It can be understood that by providing the lever structure and utilizing the attractive force of the first magnetic group and the third magnetic group and the repulsive force generated by the second magnetic group and the fourth magnetic group, a part of the latch is driven to be inserted into the first space along the first direction. Thus, by arranging the second magnetic group and the fourth magnetic group, the volumes of the first magnetic group and the third magnetic group can be effectively reduced. Because the first magnetic group and the third magnetic group are close to the bolt, when the volumes of the first magnetic group and the third magnetic group are reduced, the first magnetic group, the third magnetic group and the bolt can be prevented from interfering.

In one possible implementation manner, the display device includes a first elastic member, one end of the first elastic member is connected with the latch, and the other end of the first elastic member is connected with the first shell; a part of the bolt is clamped into the second space along the second direction under the elasticity of the first elastic piece.

It can be understood that by arranging the first elastic member, a part of the latch is clamped into the second space along the second direction under the elasticity of the first elastic member. The structure is simple, and the occupied internal space of the first shell is less. In other possible embodiments, a part of the plug can also be driven by a motor or other drive mechanism to engage in a second space of the plug space.

In one possible implementation, the display device includes a return mechanism disposed on the first housing. The restoring mechanism is used for driving a part of the bolt to slide out of the second space along a third direction, and the third direction is opposite to the second direction.

It will be appreciated that by arranging the SMA wire such that when the SMA wire is energised, a portion of the SMA wire pulls the latch to slide out of the second space in the third direction. The structure is simple, and the occupied internal space of the first shell is less. In other possible implementations, a portion of the latch may also be pulled by a motor or other drive mechanism to slide out of the second space in a third direction.

In one possible implementation, the restoring mechanism includes a slider and a second elastic member, where the slider can slide relatively with respect to the first housing. The sliding block is provided with a sliding groove, and an opening of the sliding groove faces the first shell; the bolt penetrates through the sliding groove, one part of the SMA wire is connected with the sliding block, one end of the second elastic piece is connected with the sliding block, and the other end of the second elastic piece is connected with the first shell; the sliding groove comprises a first groove wall, when the SMA wire is electrified, the SMA wire pulls the sliding block, a part of the bolt is driven by the first groove wall of the sliding block to slide out of the second space, when the SMA wire is powered off, the sliding block slides relative to the first shell under the elasticity of the second elastic piece, and a movable space is formed between the first groove wall and the bolt. It should be noted that, the sliding block can slide relatively to the first housing, including the following two cases: one is that the slider is directly slidingly connected to the first housing. The other is that a fixed plate is fixed on the first shell, and the sliding block is rotationally connected with the fixed plate.

It can be understood that by arranging the sliding block, the bolt can be limited in the thickness direction on one hand; on the other hand, when the SMA wire is electrified, the SMA wire pulls the sliding block, and part of the bolt is driven by the first groove wall of the sliding block to slide out of the second space. The sliding block has the effect of 'one object with multiple functions'.

In one possible implementation, the display device includes a limiting member fixed on the first housing, and a portion of the limiting member is located in the through hole; the limiting piece is provided with a limiting hole, and when the display device is close to the input device, a part of the bolt extends out of the limiting hole and is inserted into the inserting space of the second shell.

It is understood that the limiting piece is arranged, and a part of the limiting piece is arranged in the through hole. Thus, when a part of the bolt is arranged in the limiting hole, the part of the bolt can directly extend out of the limiting hole and be inserted into the inserting space of the second shell. Thus, in the process of installing the bolt on the first shell, the bolt can be accurately aligned with the through hole of the first shell, so that a part of the bolt can extend out of the first shell through the through hole.

In other embodiments, the stopper may not be provided. At this time, a plug space is directly provided in the first housing. The opening of the plugging space forms an opening on the outer surface of the first shell.

In one possible implementation, the display device includes a fifth magnetic group disposed on the first housing. The input device comprises a sixth magnetic group, and the sixth magnetic group is arranged on the second shell.

It can be understood that the through hole of the first housing is opposite to the opening of the plugging space of the second housing by providing the fifth magnetic group and the sixth magnetic group and utilizing the attractive force between the fifth magnetic group and the sixth magnetic group. The structure is simple, and the occupied space is small.

In one possible implementation, the docking space comprises a slot or a jack. It will be appreciated that the receptacles may be hole structures extending through the upper and lower surfaces of the detent. The slot may be a slot structure extending through the upper surface of the detent without extending through the lower surface.

In a second aspect, an embodiment of the present application provides a communication system. The communication system includes a display device and an input device.

The input device comprises a second shell and a bolt, the second shell is provided with a through hole, the through hole is communicated with the inside and the outside of the second shell, and at least part of the bolt is arranged in the second shell; the display device comprises a lock catch, the lock catch is arranged on the second shell, and the display device is provided with an inserting space.

When the display device is close to the input device, a part of the bolt extends out of the through hole along the first direction and is inserted into the inserting space, the lock catch slides relative to the second shell along the second direction and clamps the bolt, and the second direction is different from the first direction.

It will be appreciated that the latch is protected by the second housing by locating at least part of the latch within the second housing. Thus, the bolt is not easy to damage, the service life of the structure is longer, the structure of the communication system is also not easy to damage, and the service life of the structure is longer.

In addition, a part of the bolt extends out of the through hole along the first direction and is inserted into the inserting space, and the bolt is locked by sliding relative to the second shell along the second direction by utilizing the lock catch. In this way, the display device can be stably connected to the input device. Therefore, the display device and the input device of the embodiment not only can realize plugging, but also can ensure that the display device is not easy to separate from the input device after plugging, and the stability of a communication system is better.

In one possible implementation, the input device includes a slider and a first magnetic group, the latch is slidably connected to the slider, and the first magnetic group is fixed to the slider.

The display device comprises a second magnetic group, and the second magnetic group is fixed on the first shell. It should be noted that, when the first housing is provided with the fixing plate, the second magnetic group may also be fixed on the fixing plate.

When the display device is close to the input device, a part of the sliding block slides along a third direction under the attractive force of the first magnetic group and the second magnetic group, a part of the bolt extends out of the through hole along the first direction under the thrust of the sliding block and is inserted into the inserting space, and the third direction is different from the first direction. The third direction may be opposite to the second direction.

It can be understood that by arranging the slider and utilizing the attractive force of the first magnetic group and the third magnetic group, the slider is driven to slide along the third direction, and a part of the bolt extends out of the through hole along the first direction under the thrust of the slider and is inserted into the insertion space. The structure is simple, and the occupied internal space of the second shell is less. In other possible implementations, the slider may be driven to slide in the third direction by a motor or other driving mechanism.

In one possible implementation, the slider includes a first inclined surface and the latch includes a third inclined surface that faces the first inclined surface. And one part of the bolt extends out of the through hole along the first direction through the cooperation of the first inclined surface and the third inclined surface under the thrust of the sliding block and is inserted into the inserting space.

It can be understood that by the cooperation of the first inclined surface and the third inclined surface, a part of the bolt is converted into a part which extends out of the through hole along the first direction under the thrust of the sliding block along the third direction and is inserted into the inserting space. The structure is simple, and the occupied internal space of the second shell is less.

In one possible implementation, when the display device is far away from the input device, the first magnetic group and the second magnetic group are staggered in a third direction. Thus, when the first magnetic group and the second magnetic group are close to each other, the second magnetic group can receive the attractive force of the first magnetic group along the third direction. The second magnetic group can drive the sliding block to slide along the third direction. It can be understood that when this realization mode drives the gliding structure of slider along the third direction comparatively simple, occupies the space of second casing less.

In one possible implementation, the display device includes an SMA wire, a portion of which is connected to the latch. When the SMA wire is electrified, the SMA wire pulls the lock catch to slide relative to the first shell along a third direction, the lock catch is separated from the bolt, and the third direction can be opposite to the second direction.

It will be appreciated that by providing the SMA wire such that when the SMA wire is energised, the SMA wire pulls the catch to slide in a third direction relative to the first housing, the catch being separated from the latch.

In other possible implementations, the latch may also be pulled to slide in a third direction relative to the first housing by a motor or other drive mechanism.

In one possible implementation, the input device includes an elastic member, one end of the elastic member is connected to the slider, and the other end of the elastic member is connected to the second housing.

When the lock catch is separated from the bolt, a part of the bolt is pulled out of the inserting space, the attractive force of the first magnetic group and the second magnetic group is reduced, the sliding block slides along the second direction under the elastic force of the elastic piece, and a part of the bolt extends into the second shell through the through hole along the fourth direction under the tensile force of the sliding block, and the fourth direction can be opposite to the first direction.

It can be understood that by providing the elastic member such that when the lock catch is separated from the plug pin, a portion of the plug pin is pulled out from the insertion space, the attractive force of the first magnetic group and the second magnetic group is reduced, and the slider slides in the second direction under the elastic force of the elastic member. The structure is simple, and the occupied internal space of the second shell is less. In other possible implementations, the slider may be driven to slide in the second direction by a motor or other driving mechanism.

In one possible implementation, the slider includes a second inclined surface and the latch includes a fourth inclined surface that faces the second inclined surface.

A part of the bolt is under the tensile force of the sliding block and extends into the second shell through the through hole along the fourth direction through the cooperation of the second inclined surface and the fourth inclined surface.

It will be appreciated that by the engagement of the second inclined surface with the fourth inclined surface, a portion of the bolt is caused to extend into the second housing through the through hole in the fourth direction under tension of the slider. The structure is simple, and the occupied internal space of the second shell is less.

When the SMA wire is electrified, the SMA wire pulls the lock catch to extrude the first elastic piece and slide along the third direction relative to the second shell, the lock catch is separated from the bolt, a part of the bolt is pulled out of the plug-in space, a part of the door plate stretches into the plug-in space under the elasticity of the second elastic piece, the SMA wire is powered off, and the lock catch is propped against the door plate under the second elastic piece. Therefore, on one hand, one part of the door plate stretches into the inserting space under the elasticity of the second elastic piece, so that external dust or water vapor and the like can be prevented from entering the first shell from the inserting space; on the other hand, the lock catch is abutted against the door plate under the second elastic piece, so that the door plate can be prevented from falling out of the inserting space.

Detailed Description

In describing embodiments of the present application, it should be noted that the term "coupled" should be interpreted broadly, unless otherwise explicitly stated and defined, for example, the term "coupled" may be either detachably coupled or non-detachably coupled; may be directly connected or indirectly connected through an intermediate medium. Wherein, the 'fixed connection' can be that the relative position relationship is unchanged after being connected with each other. A "rotational connection" may be one that is connected to each other and that is capable of relative rotation after connection. A "sliding connection" may be one that is connected to each other and that is capable of sliding relative to each other after connection. The term "integrally formed" refers to a component that is joined to another component during the formation of one of the components, without the need for re-working (e.g., bonding, welding, snap-fit, screw-connection) the two components together. References to orientation terms, such as "bottom", "back", "side", "inner", "outer", "left", "right", etc., in the embodiments of the present application are merely with reference to the orientation of the drawings, and thus are used in order to better and more clearly illustrate and understand the embodiments of the present application, rather than to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the embodiments of the present application. "plurality" means at least two.

Fig. 1 is a schematic structural diagram of a communication system 1 according to an embodiment of the present application in a separated state. Fig. 2 is a partially exploded schematic view of the communication system 1 shown in fig. 1. Fig. 3 is a schematic structural diagram of the communication system 1 according to the embodiment of the present application in a connected state.

As shown in fig. 1 to 3, the communication system 1 includes a display device 1000 and an input device 2000. The display device 1000 may be a device having a display function such as a tablet computer (tablet personal computer), a mobile phone, a laptop (laptop computer), a Personal Digital Assistant (PDA), or the like. The input device 2000 may be a touch pad, a keyboard, a mobile phone, a tablet computer, a laptop computer, a personal digital assistant, or the like with an input function. The display device 1000 shown in fig. 1 to 3 is exemplified by a tablet computer, and the input device 2000 is exemplified by a touch pad.

As shown in fig. 1 to 3, the communication system 1 includes a disconnected state and a connected state.

When the communication system 1 is in a separated state, the display device 1000 is separated from the input device 2000, and the display device 1000 and the input device 2000 can be used independently. For example, when the display device 1000 is a tablet computer and the input device 2000 is a touch pad, the display device 1000 may be directly used for watching a movie, and the input device 2000 may be used in combination with other devices (e.g. a computer), for example, may be used as a touch pad of the computer.

In one embodiment, when the display device 1000 is separated from the input device 2000, the display device 1000 and the input device 2000 may still be used in combination. For example, the display device 1000 and the input device 2000 may be connected by a wireless signal. Thus, when the input device 2000 is far away from the display device 1000 and is within the communication connection range, the user can still display the related content at the content input by the input device 2000, and the display device 1000 displays the related content.

When the communication system 1 is in a connected state, the display device 1000 is fixed to the input device 2000, and the input device 2000 can be a device for inputting instructions to the display device 1000. The display device 1000 is in communication with the input device 2000, i.e. the display device 1000 and the input device 2000 may be connected wirelessly or by wire. For example, when the display device 1000 is a tablet computer and the input device 2000 is a touch pad, a user may input content in the input device 2000, and the display device 1000 may display related content.

It is understood that the input device 2000 may support the display device 1000 when the input device 2000 is fixed to the display device 1000. In this way, the user does not need to hold the display device 1000 or support the display device 1000 by an additional supporting stand during the display of the display device 1000. The structure of the communication system 1 is relatively simple. In this embodiment, the input device 2000 may be used as a device for inputting instructions to the display device 1000, or may support the display device 1000. The input device 2000 has a "one-thing-multiple-use" effect.

As shown in fig. 1 to 3, the display device 1000 includes a first connection assembly 100 and a first housing 200. The first connection assembly 100 is disposed on the first housing 200. The input device 2000 includes a second connection assembly 300 and a second housing 400. The second connection assembly 300 is disposed on the second housing 400. It should be noted that, since the first connecting assembly 100 is located inside the first housing 200, the second connecting assembly 300 is located inside the second housing 400, and both fig. 1 and 3 schematically illustrate the first connecting assembly 100 and the second connecting assembly 300 with dashed lines.

In the present embodiment, when the communication system 1 is in the connected state, the first connection assembly 100 is connected with the second connection assembly 300. In this way, the display device 1000 can be stably mounted on the input device 2000. The specific structure of the first connection assembly 100 and the second connection assembly 300 is described in detail below with reference to the accompanying drawings.

In some embodiments, when the first and second connection assemblies 100 and 300 are connected, the first and second housings 200 and 400 may be disposed at an angle therebetween. Illustratively, the first housing 200 and the second housing 400 may be 90 °, 100 °, 120 °, 145 °, 160 °, or the like.

In some embodiments, as shown in fig. 1, the first connection assembly 100 may be entirely located inside the first housing 200 when the communication system 1 is in a disconnected state. In this way, on the one hand, the first connecting component 100 is not exposed outside the first housing 200, and the first housing 200 has better appearance consistency and better accords with the visual and aesthetic effects of human body. On the other hand, when the display device 1000 is externally impacted, the first connection assembly 100 is not easily deformed or even damaged by direct impact.

It is understood that, when the communication system 1 is in the separated state, the positional relationship between the second connection assembly 300 and the second housing 400 may also refer to the positional relationship between the first connection assembly 100 and the first housing 200. And in particular will not be described in detail herein.

In the present embodiment, the first connection assembly 100 and the second connection assembly 300 may constitute a first connection mechanism of the communication system 1. The first connection may be used as a left connection of the communication system 1. The communication system 1 may further comprise a second connection mechanism. The second connection may be used as a right connection of the communication system 1. In this way, the connection strength and stability between the display device 1000 and the input device 2000 can be enhanced.

The second connection mechanism and the first connection mechanism may be of the same or similar structure, symmetrical or partially symmetrical structure, or different structures, for example. In some embodiments, the second connection mechanism and the first connection mechanism may be symmetrical structures, and the basic design of the component structure of the second connection mechanism, the design of the connection relationship between the components, and the design of the connection relationship between the components and other structures except the assembly may refer to the related schemes of the first connection mechanism, while allowing the second connection mechanism and the first connection mechanism to be slightly different in the detailed structure or the positional arrangement of the components.

First, the specific structure of the first coupling assembly 100 will be described in detail with reference to the accompanying drawings. Fig. 4 is a partially exploded view of the first coupling assembly 100 shown in fig. 2.

As shown in fig. 4, the first connection assembly 100 includes a fixing plate 11, a lever 12, a latch 13, a restoring mechanism 14, a first magnetic set 15a, a second magnetic set 15b, a first elastic member 16, a stopper 17, and a torsion spring 18.

Fig. 5 is a schematic view of the structure of the fixing plate 11 shown in fig. 4 at different angles. For convenience of description, exemplarily, a length direction of the fixing plate 11 is defined as an X-axis direction, a width direction of the fixing plate 11 is defined as a Y-axis direction, and a thickness direction of the fixing plate 11 is defined as a Z-axis direction. In the present embodiment, the negative direction of the Y axis is the first direction. The positive direction of the X-axis is the second direction. The negative direction of the X-axis is the third direction. Thus, the first direction is different from the second direction. The second direction is opposite to the third direction. It will be appreciated that the coordinate system of the communication system 1 may also be flexibly set according to specific requirements. At this time, the first direction and the second direction can be flexibly set according to specific requirements.

As shown in fig. 5, the fixing plate 11 has a first face 111 and a second face 112 disposed opposite to each other.

Illustratively, the fixed plate 11 has a sliding space 113. The sliding space 113 penetrates the first face 111 and the second face 112 of the fixed plate 11. The number of the sliding spaces 113 may be one or a plurality. When the number of the sliding spaces 113 is plural, the plural sliding spaces 113 are disposed at intervals. For example, fig. 5 illustrates that the number of the sliding spaces 113 is three.

Illustratively, the sliding space 113 includes a first subspace 1131 and a second subspace 1132. The second subspace 1132 communicates with the first subspace 1131. The first subspace 1131 and the second subspace 1132 may be disposed at an angle. For example, the angle between the first subspace 1131 and the second subspace 1132 is 90 °. The sliding space 113 may have an "L" shape at this time.

Illustratively, the extending direction of the first subspace 1131 may be the Y-axis direction, and the extending direction of the second subspace 1132 may be the X-axis direction.

Illustratively, the fixed plate 11 is provided with a first through hole 114. The first through hole 114 penetrates the first face 111 and the second face 112 of the fixing plate 11. The first through hole 114 may be disposed spaced apart from the sliding space 113. It is understood that the number of first through holes 114 is not limited to two as shown in fig. 5. When the number of the first through holes 114 is plural, the plural first through holes 114 are disposed at intervals.

Illustratively, the fixed plate 11 is also provided with a second through hole 115. The second through hole 115 penetrates the first face 111 and the second face 112 of the fixing plate 11. The second through hole 115 is spaced apart from the first through hole 114 and the sliding space 113.

Illustratively, the securing plate 11 includes a main body portion 116 and an extension portion 117. Extension 117 may be located at the bottom of body portion 116. Wherein, the sliding space 113 and the first through hole 114 may be located at the main body 116. The second through hole 115 may be located at the extension 117. Fig. 5 schematically shows the main body 116 and the extension 117 by broken lines.

It will be appreciated that the mounting plate 11 may be a unitary structure, i.e., the body portion 116 and the extension portion 117 are integrally formed. The fixing plate 11 may also be a spliced structure. For example, the body portion 116 and the extension portion 117 may be formed as a unitary structure by a splice (e.g., a mortise and tenon process) or a fastening (e.g., a welding, bonding, etc. process). The application is not particularly limited.

Fig. 6 is a schematic view of the lever 12 of fig. 4 at a different angle.

As shown in fig. 6, the lever 12 has a first face 121 and a second face 122 disposed opposite. The lever 12 is provided with a rotation hole 123. A rotation hole 123 penetrates the first face 121 and the second face 122 of the lever 12.

Illustratively, the lever 12 is also provided with a boss 124. The boss 124 is connected to the first face 121 of the lever 12. The boss 124 may also be integrally formed with the lever 12.

Illustratively, the lever 12 includes a first shaft portion 125, a second shaft portion 126, and a rotating portion 127. The rotating portion 127 is connected between the first and second shaft portions 125 and 126. At this time, the second shaft 126 is connected to a side of the rotating portion 127 remote from the first shaft 125. The rotation hole 123 may be located at the rotation part 127. The post 124 may be located at the first stem 125. In other embodiments, the lever 12 may not include the second stem 126.

It will be appreciated that the lever 12 may be a unitary structure, i.e., the first and second shaft portions 125, 126 and the rotating portion 127 are integrally formed. The lever 12 may also be a spliced structure. For example, the first rod portion 125, the second rod portion 126, and the rotating portion 127 may be formed as a unitary structure by a splicing process (e.g., a mortise and tenon process) or a fixing process (e.g., a welding, bonding, etc.). The application is not particularly limited.

In one embodiment, the first stem 125 and the second stem 126 may be disposed at an angle, i.e., the first stem 125 is disposed obliquely with respect to the second stem 126. Illustratively, the angle between the second stems 126 is in the range of 90 ° to 180 °. For example 90 °,135 ° or 180 °.

In one embodiment, a portion of the first stem 125 and the rotating portion 127 enclose a first slot 128a. The first slot 128a may be configured to receive the first magnetic group 15a.

In one embodiment, a portion of the second stem 126 and the rotating portion 127 enclose a second slot 128b. The second slot 128b may be used to receive the second magnetic group 15b.

Fig. 7 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 7 illustrates an assembly schematic between the fixed plate 11 and the lever 12.

As shown in fig. 7, and in combination with fig. 5 and 6, the lever 12 is rotatably connected to the fixing plate 11.

Illustratively, a portion of the extension 117 of the fixed plate 11 is inserted into the rotation hole 123 of the rotation portion 127 of the lever 12. The lever 12 may rotate relative to the fixed plate 11 with the extension 117 of the fixed plate 11 as a supporting point.

In addition, the present embodiment may be configured such that the engaging member 11a (e.g., a screw) is inserted through the second through hole 115 of the extension portion 117 of the fixing plate 11 and the rotation hole 123 of the lever 12, and the engaging member 11a is fixedly coupled to the fixing plate 11 (e.g., the screw is locked to the hole wall of the second through hole 115). In this way, the rotating portion 127 of the lever 12 can be restrained between the head of the fitting 11a and the fixed plate 11, so that the lever 12 is not easily detached from the fixed plate 11 when the lever 12 rotates relative to the fixed plate 11.

In other embodiments, the lever 12 may be rotatably coupled to the fixed plate 11 by other arrangements. The application is not particularly limited.

In one embodiment, the first portion 125 of the lever 12 may be located at the bottom of the body portion 116 of the fixed plate 11. Thus, when the lever 12 is rotated relative to the fixed plate 11, the first rod portion 125 of the lever 12 may be moved toward or away from the body portion 116 of the fixed plate 11.

Fig. 8 is a schematic view of a portion of the first coupling assembly 100 shown in fig. 7 at a different angle.

As shown in fig. 8, the rotating portion 127 of the lever 12 may be provided with a first receiving groove 129. A portion of the extension 117 of the fixing plate 11 may be located in the first receiving groove 129 of the lever 12. It will be appreciated that when the lever 12 is rotated relative to the fixed plate 11, the side of the extension 117 of the fixed plate 11 may abut against the groove wall of the first receiving groove 129 of the lever 12, thereby restricting the lever 12 from continuing to rotate. In other words, the angle of rotation of the lever 12 with respect to the fixed plate 11 can be restricted by the engagement of the extension 117 with the first receiving groove 129.

Fig. 9 is a schematic view of the latch 13 shown in fig. 4 at a different angle. Fig. 10 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 10 illustrates an assembled schematic view between the fixing plate 11, the lever 12, the latch 13, and the first elastic member 16. Fig. 11a is a schematic view of a portion of the first coupling assembly 100 shown in fig. 10 at a different angle.

As shown in fig. 9 to 11a, the latch 13 is slidably coupled to the fixing plate 11.

Illustratively, the latch 13 has a boss 131. The convex portion 131 may have a cylindrical shape. The number of projections 131 is not limited to the three illustrated in fig. 11 a. The three protrusions 131 may be arranged in a triangle. In other embodiments, the arrangement, number, and shape of the protrusions 131 are not particularly limited.

Wherein the protrusion 131 of the latch 13 may be located in the sliding space 113 of the fixed plate 11 (fig. 5 illustrates the structure of the protrusion 131 from different angles). Illustratively, the plurality of protrusions 131 are disposed in the plurality of sliding spaces 113 in one-to-one correspondence.

It will be appreciated that the latch 13 can be slid in a fixed direction with respect to the fixed plate 11 by the engagement between the protrusion 131 of the latch 13 and the sliding space 113 of the fixed plate 11. For example, the sliding space 113 includes a first subspace 1131 and a second subspace 1132. The extending direction of the first subspace 1131 is the Y-axis direction, and the extending direction of the second subspace 1132 is the X-axis direction. Thus, by the engagement between the convex portion 131 of the latch 13 and the sliding space 113 of the fixed plate 11, the latch 13 can slide in the Y-axis direction with respect to the fixed plate 11 when the convex portion 131 of the latch 13 is located in the first subspace 1131, and the latch 13 can slide in the X-axis direction with respect to the fixed plate 11 when the convex portion 131 of the latch 13 is located in the second subspace 1132.

In other embodiments, the arrangement of the protruding portion 131 of the latch 13 and the sliding space 113 of the fixing plate 11 may be reversed, that is, the latch 13 is provided with the sliding space 113 and the fixing plate 11 is provided with the protruding portion 131.

In other embodiments, the latch 13 may be slidably coupled to the fixed plate 11 in other ways.

As shown in fig. 9 to 11a, the latch 13 is slidably connected to the lever 12.

Illustratively, the latch 13 has a bar-shaped aperture 132. The bar-shaped hole 132 may extend in the X-axis direction. The boss 124 of the lever 12 (fig. 6 illustrates the structure of the boss 124 from a different perspective) may be located within a bar-shaped aperture 132 of the latch 13. It will be appreciated that by engaging the boss 124 of the lever 12 with the bar-shaped aperture 132 of the latch 13, the latch 13 can slide in the X-axis direction as the latch 13 slides relative to the lever 12.

It should be noted that fig. 10 illustrates that the boss 124 of the lever 12 is inserted into the bar-shaped hole 132 of the latch 13 from the side of the second face 134 of the latch 13. In other embodiments, the boss 124 of the lever 12 may also be inserted into the bar-shaped hole 132 of the latch 13 from the side of the first face 133 of the latch 13.

As shown in fig. 9 to 11a, one end of the first elastic member 16 is fixedly connected to the latch 13, and the other end is fixedly connected to the first housing 200 (see fig. 2). The first resilient member 16 may be a spring, for example. In other embodiments, the first elastic member 16 may be another elastic member such as a spring plate or rubber.

Illustratively, the latch 13 is provided with a hook 135. One end of the first elastic member 16 may be hooked on the hook 135 of the latch 13.

The other end of the first elastic member 16 may be hooked on the first housing 200, for example.

In other embodiments, the connection manner of the first elastic member 16 and the latch 13 and the first housing 200 is not particularly limited.

In other embodiments, the other end of the first elastic member 16 may be fixedly connected to the fixing plate 11 instead of being fixedly connected to the first housing 200.

Illustratively, the first elastic member 16 is in a stretched state. Thus, the first elastic member 16 may exert elastic force on the plug pin 13. In one embodiment, the first elastic member 16 may apply an elastic force to the plug pin 13 in a positive direction of the X-axis.

Fig. 11b is a schematic view of a part of the structure of the first connection assembly 100 shown in fig. 2 when the communication system 1 is in a connected state.

As shown in fig. 10, 11a and 11b, when the lever 12 rotates in a clockwise direction with respect to the fixing plate 11, the first rod portion 125 and the boss 124 of the lever 12 may apply a negative force in the Y-axis direction to the socket 13. Since the convex portion 131 of the latch 13 is located in the first subspace 1131 of the sliding space 113 of the fixed plate 11, the convex portion 131 of the latch 13 is free from a stopper in the negative direction of the Y-axis. At this time, the lever 12 may drive the latch 13 to slide along the negative direction of the Y axis until sliding to the bottom of the first subspace 1131. In other words, the protrusion 131 of the latch 13 slides in the extending direction of the first subspace 1131 of the sliding space 113 of the fixed plate 11 until sliding to the bottom of the first subspace 1131. At this time, the convex portion 131 of the latch 13 faces the second subspace 1132 of the sliding space 113 of the fixed plate 11. Since the protrusion 131 of the latch 13 has no blocking object in the positive direction of the X axis, and the first elastic member 16 applies an elastic force to the latch 13 in the positive direction of the X axis, the protrusion 131 of the latch 13 can slide in the positive direction of the X axis in the second subspace 1132 of the sliding space 113 of the fixed plate 11 under the tensile force of the first elastic member 16, that is, the latch 13 can slide in the positive direction of the X axis with respect to the fixed plate 11 under the tensile force of the first elastic member 16. Further, since the latch 13 slides in the positive direction of the X axis with respect to the fixed plate 11, and the lever 12 is rotated with respect to the fixed plate 11 (i.e., the lever 12 is stationary in the positive direction of the X axis with respect to the fixed plate 11), the latch 13 slides in the positive direction of the X axis with respect to the lever 12. Illustratively, the boss 124 of the lever 12 is slidable in the negative X-axis direction relative to the bar aperture 132 of the latch 13. It will be appreciated that the position of the boss 124 of the lever 12 can be slid from the position of fig. 11a to the position illustrated in fig. 11 b.

Fig. 12 is an exploded schematic view of the return mechanism 14 shown in fig. 4.

As shown in fig. 12, the restoring mechanism 14 includes a force application member 141, a slider 142, and a second elastic member 143.

Illustratively, the force applying member 141 may be a shape memory alloy (shape memory alloy, SMA) wire, also referred to as a memory metal wire. The urging member 141 may be a member or a device having an urging force such as a motor.

The second elastic member 143 may be a spring, for example. In other embodiments, the second elastic member 143 may be a resilient member such as a spring plate or rubber.

Fig. 13 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 13 illustrates an assembly schematic between the fixed plate 11 and the slider 142. Fig. 14 is a schematic structural view of a portion of the first connection assembly shown in fig. 13 between a connected state and a disconnected state of the communication system 1.

As shown in fig. 13 and 14, the slider 142 is slidably connected to the fixing plate 11.

Illustratively, the slider 142 has a first face 1421 and a second face 1422 disposed opposite thereto. The slider 142 is provided with a bar-shaped hole 1423. The bar-shaped hole 1423 penetrates the first face 1421 and the second face 1422 of the slider 142. The number of the bar-shaped holes 1423 is not limited to two as shown in fig. 13. Two bar-shaped holes 1423 are spaced apart. The extending direction of the bar-shaped hole 1423 may be the X-axis direction.

Illustratively, the mating member 11b is fixedly connected to the fixing plate 11 (e.g., a screw is lockingly connected to a wall of the first through hole 114) by passing the mating member 11b (e.g., a screw) through the bar-shaped hole 1423 of the slider 142 and the first through hole 114 of the fixing plate 11. In this way, the slider 142 can be restrained between the fitting 11b and the fixing plate 11. Since the extending direction of the bar-shaped hole 1423 may be the X-axis direction, the slider 142 may slide with respect to the fixing plate 11 in the X-axis direction.

In other embodiments, the slider 142 may be slidably connected to the fixing plate 11 by other connection methods.

As shown in fig. 13 and 14, when the slider 142 is in the position illustrated in fig. 13, the slider 142 can slide in the negative direction of the X-axis with respect to the fixed plate 11 until it slides to the position illustrated in fig. 14. Wherein fig. 13 illustrates by dashed lines with arrows the direction in which the slider 142 can slide. When the slider 142 is in the position illustrated in fig. 14, the slider 142 can slide in the positive direction of the X-axis with respect to the fixed plate 11 until it slides to the position illustrated in fig. 13. Wherein fig. 14 illustrates by dashed lines with arrows the direction in which the slider 142 can slide.

Fig. 15 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 15 illustrates an assembly schematic between the fixed plate 11 and the force application member 141, the slider 142, and the second elastic member 143.

As shown in fig. 12 and 15, a part of the urging member 141 is connected to the slider 142.

In one embodiment, the force applicator 141 includes a first end 1411, a middle 1412, and a second end 1413. A middle portion 1412 of the force application member 141 is connected to the slider 142. One of the first end 1411 and the second end 1413 of the urging member 141 is electrically connected to a positive electrode of a power source (not shown), and the other is electrically connected to a negative electrode of the power source. The force application member 141 and the power source may form a current loop.

Illustratively, the slider 142 has a first stud 1424. In addition, the first connection assembly 100 further includes a mating member 11c. The area of the head of the mating piece 11c is larger than the area of the stem of the mating piece 11c. The rod portion has a through hole. The first stud 1424 of the slider 142 may be located in the through hole of the mating element 11c. The first protrusion 1424 of the slider 142 is tightly fitted into the through hole of the fitting 11c. Wherein the middle portion 1412 of the force application member 141 may be looped over the stem portion of the mating member 11c.

In other embodiments, the engaging member 11c may be fixedly connected to the slider 142 by other arrangements.

In other embodiments, the force applying member 141 may be coupled to the slider 142 in other ways.

As shown in fig. 15, one end of the second elastic member 143 is fixedly connected to the slider 142, and the other end thereof can be fixedly connected to the first housing 200 (see fig. 2).

Illustratively, the slider 142 is provided with a second stud 1425. The second stud 1425 is spaced apart from the first stud 1424. One end of the second elastic member 143 may be hooked on the second protrusion 1425 of the slider 142.

The other end of the second elastic member 143 may be hooked on the first housing 200, for example.

In other embodiments, the connection manner of the second elastic member 143 with the slider 142 and the first housing 200 is not particularly limited.

In other embodiments, the shape of the fixing plate 11 is changed such that the other end of the second elastic member 143 may be fixedly coupled to the fixing plate 11 instead of the first housing 200.

As shown in fig. 13 to 15, the action of the force application member 141 is described taking the SMA wire as an example of the force application member 141. The SMA wires are energized and create a contraction force that applies a negative force to the slider 142 along the X-axis. The SMA wire may drive the slider 142 to slide in the negative X-axis direction with respect to the fixed plate 11. At this time, the slider 142 slides from the position illustrated in fig. 13 to the position illustrated in fig. 14. At this time, the second elastic member 143 may be in a stretched state. The second elastic member 143 applies a force in the positive direction of the X-axis to the slider 142. When the SMA wire is de-energized, the second elastic member 143 may pull the slider 142 to slide in the positive direction of the X-axis. At this time, the slider 142 slides from the position illustrated in fig. 14 to the position illustrated in fig. 13.

Illustratively, in the position illustrated in fig. 14, the second elastic member 143 is in a stretched state. While in the position illustrated in fig. 13, the second elastic member 143 may be in a stretched state or in a natural state.

In other embodiments, the slider 142 may be pulled by the force member 141 with other structures to slide in the negative direction of the X-axis relative to the fixed plate 11. For example, the force application member 141 is a motor.

Fig. 16 is a partial schematic structural view of the first connection assembly 100 shown in fig. 2 when the communication system 1 is in a connected state. In other words, fig. 16 is a schematic view of a part of the first connection assembly 100 illustrated in fig. 3. Illustratively, fig. 16 illustrates an assembled schematic view between the fixing plate 11, the lever 12, the latch 13, the restoring mechanism 14, and the first elastic member 16.

As shown in fig. 16, the latch 13 is slidably connected to the slider 142.

Illustratively, the slider 142 is provided with a runner 1426. The runner 1426 includes a second slot wall 1426a and a first slot wall 1426b. The length of the slide groove 1426 in the X-axis direction is longer than the dimension of the latch 13 in the X-axis direction. The length of the sliding groove 1426 in the X-axis direction may be a distance between the second groove wall 1426a and the first groove wall 1426b.

The opening of the sliding slot 1426 faces the fixing plate 11, that is, the opening of the sliding slot 1426 faces the first housing 200 (see fig. 2). The sliding groove 1426 and the fixing plate 11 may define a movable space. A portion of the latch 13 passes through the runner 1426 from one side of the slider 142 to the other side of the slider 142. At this time, a portion of the latch 13 may be located in the space. The latch 13 can slide in the Y-axis direction with respect to the slider 142 in this space. In addition, since the length of the sliding groove 1426 in the X-axis direction is longer than the dimension of the latch 13 in the X-axis direction, the latch 13 can also slide in the X-axis direction with respect to the slider 142 in the space.

Fig. 17a is a schematic view of a portion of the first connection assembly 100 shown in fig. 16 at different angles. Fig. 17b is a schematic structural diagram of the first connection assembly 100 shown in fig. 2 between the connected state and the disconnected state of the communication system 1.

As shown in fig. 16, 17a and 17b, when the SMA wire (i.e. the force application member 141) drives the sliding block 142 to slide along the negative direction of the X axis relative to the fixed plate 11, the sliding block 142 can drive the latch 13 to slide along the negative direction of the X axis. It is understood that the sliding block 142 may drive the latch 13 to slide along the negative direction of the X-axis through the first slot wall 1426b of the slot 1426. At this time, the protrusion 131 of the latch 13 may slide in the negative direction of the X-axis in the second subspace 1132 of the sliding space 113 of the fixed plate 11 under the tensile force of the slider 142. In addition, the latch 13 slides in the negative direction of the X axis with respect to the lever 12. Illustratively, the boss 124 of the lever 12 is slidable in the positive X-axis direction relative to the bar-shaped aperture 132 of the latch 13. The position of the stud 124 of the lever 12 slides from the position illustrated in fig. 16 and 17a to the position illustrated in fig. 17 b.

As shown in fig. 15 and 16, when the SMA wire (i.e., the force application member 141) is powered off, the length of the SMA wire can be restored to the original length, and the second elastic member 143 pulls the slider 142 to slide in the positive direction of the X-axis relative to the fixed plate 11. At this time, since the length of the sliding groove 1426 in the X-axis direction is greater than the dimension of the latch 13 in the X-axis direction, the slider 142 does not drive the latch 13 to slide along the positive direction of the X-axis. When the slider 142 is slid to the position of fig. 14, the second groove wall 1426a of the sliding groove 1426 may contact the latch 13, and the first groove wall 1426b of the sliding groove 1426 is separated from the latch 13, that is, a movable space is formed between the first groove wall 1426b and the latch 13. In other embodiments, the second slot wall 1426a of the slot 1426 may also be out of contact with the latch 13 when the slider 142 slides to the fig. 14 position. It will be appreciated that the space between the first slot wall 1426b of the slot 1426 and the latch 13 may be used so that the latch 13 does not interfere with the slider 142 when the latch 13 slides in the positive X-axis direction.

In other embodiments, other driving mechanisms may be used to drive the sliding pin 13 to slide in the negative X-axis direction by the driving mechanism.

Fig. 18 is a schematic view of the stopper 17 shown in fig. 4 at a different angle. Fig. 19 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 19 illustrates an assembled schematic view between the fixing plate 11, the lever 12, the latch 13, the restoring mechanism 14, the first elastic member 16, and the stopper 17.

As shown in fig. 18 and 19, the stopper 17 may be fixedly connected with the first housing 200 (refer to fig. 2).

Illustratively, the limiter 17 may be locked to the first housing 200 (see fig. 2) by fasteners (screws, etc.).

In other embodiments, the limiting member 17 may be fixedly connected to the fixing plate 11.

As shown in fig. 18 and 19, the latch 13 is slidably connected to the stopper 17.

Illustratively, the stop 17 is provided with a stop aperture 171. A portion of the latch 13 extends into the limiting aperture 171 from one side of the limiting member 17. At this time, a part of the plug 13 is located in the limiting hole 171. Thus, in the Z-axis direction, the latch 13 can be prevented from being separated along the Z-axis direction by the cooperation of the limiting member 17 and the first housing 200, and the connection between the latch 13 and the fixing plate 11 is more stable.

Fig. 20 is a schematic structural view of a portion of the first connection assembly 100 shown in fig. 19 when the communication system 1 is in a connected state.

As shown in fig. 19 and 20, when the lever 12 rotates in a clockwise direction with respect to the fixing plate 11, the lever 12 may drive the latch 13 to slide in a negative direction of the Y axis. At this time, a portion of the latch 13 may protrude through the stopper hole 171 of the stopper 17, that is, the position of the latch 13 with respect to the stopper 17 may be changed from the position of fig. 19 to the position of fig. 20.

In addition, when the latch 13 can slide in the positive direction of the X axis relative to the fixed plate 11 under the tension of the first elastic member 16, the latch 13 can also slide in the positive direction of the X axis relative to the stopper 17.

In addition, when the SMA wire (i.e. the force application member 141) drives the slider 142 to slide along the negative direction of the X axis relative to the fixed plate 11, the slider 142 can drive the latch 13 to slide along the negative direction of the X axis. At this time, the latch 13 can slide in the negative direction of the X axis with respect to the stopper 17.

Fig. 21 is a schematic view of a portion of the first connection assembly 100 shown in fig. 2. Illustratively, fig. 21 illustrates an assembled schematic view among the fixing plate 11, the lever 12, the latch 13, the restoring mechanism 14, the first magnetic group 15a, the second magnetic group 15b, the first elastic member 16, the stopper 17, and the torsion spring 18. Fig. 22 is a schematic structural view of a portion of the first connection assembly 100 shown in fig. 21 when the communication system 1 is in a connected state.

As shown in fig. 21 and 22, the first magnetic group 15a is fixed to the first rod portion 125 of the lever 12. The second magnetic group 15b is fixed to the second stem 126 of the lever 12.

Illustratively, the first magnetic group 15a may be received within the first slot 128a of the lever 12. The second magnetic group 15b may be received in the second slot 128b of the lever 12.

Illustratively, the first magnetic group 15a may be a halbach array. The first magnetic group 15a may include a first magnet 151a, a second magnet 152a, and a third magnet 153a. The first magnet 151a and the third magnet 153a have magnetic lines of force in opposite directions. The magnetic force line direction of the second magnet 152a is perpendicular to the magnetic force line direction of the first magnet 151 a.

In other embodiments, the first magnet 151a may be opposite to the magnetic force lines of the third magnet 153 a. The direction of magnetic force lines of the second magnet 152a may be opposite to that of the first magnet 151 a.

In other embodiments, the first connection assembly 100 may not include the second magnetic group 15b. At this time, the lever 12 may not include the second rod portion 126.

As shown in fig. 21 and 22, the structure of the second magnetic group 15b may be described with reference to the related description of the first magnetic group 15a, and the magnetic force lines of the first magnet 151b, the second magnet 152b, and the third magnet 153b of the second magnetic group 15b are opposite to the magnetic force lines of the first magnet 151a, the second magnet 152a, and the third magnet 153a of the first magnetic group 15 a.

As shown in fig. 21 and 22, the torsion spring 18 includes a first end portion 181, a middle portion 182, and a second end portion 183. The middle portion 182 of the torsion spring 18 may be adapted for fixed connection with the first housing 200 (see fig. 2).

Illustratively, the lever 12 is provided with a limit groove 91 (fig. 8 illustrates the structure of the limit groove 91 at another angle). A portion of the first end 181 of the torsion spring 18 may be disposed within the limit slot 91 and in contact with a slot wall of the limit slot 91. The first end 181 of the torsion spring 18 may apply a negative force in the Y-axis direction to the slot wall of the limit slot 91. At this time, the first end 181 of the torsion spring 18 may apply a negative force in the Y-axis direction to the second lever 126. Thus, the first rod portion 125 of the lever 12 may tilt in the positive Y-axis direction with respect to the second rod portion 126.

As shown in fig. 21 and 22, when the second rod portion 126 of the lever 12 receives a force in the positive direction of the Y-axis and/or the first rod portion 125 receives a force in the negative direction of the Y-axis, the first rod portion 125 of the lever 12 may overcome the spring force of the torsion spring 18, thereby allowing the lever 12 to rotate in a clockwise direction (illustrated by the dashed line with an arrow in fig. 21). At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the negative direction of the Y axis. When the second rod portion 126 of the lever 12 is no longer subject to a force in the positive direction of the Y-axis and/or the first rod portion 125 is no longer subject to a force in the negative direction of the Y-axis, the first rod portion 125 of the lever 12 may rotate in a counter-clockwise direction (illustrated in fig. 22 by the dashed lines with arrows) under the spring force of the torsion spring 18. At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the positive direction of the Y axis. The second rod portion 126 of the lever 12 may be subjected to a positive force in the Y-axis and the first rod portion 125 may be subjected to a negative force in the Y-axis, as will be described in detail below in connection with the second linkage assembly 300 of the input device 2000.

Fig. 23 is a schematic structural view of the first housing 200 shown in fig. 2. Fig. 24 is a partial enlarged view of the first housing 200 shown in fig. 23 at A1. Fig. 25 is a schematic view of a part of the structure of the display device 1000 shown in fig. 1. Illustratively, fig. 25 illustrates a partial enlarged view of the first housing 200 assembled with the first connection assembly 100 at A1.

As shown in fig. 23 to 25, the fixing plate 11 is fixedly coupled to the first housing 200. The fixing plate 11 may be locked to the first housing 200 by a fastener.

In one embodiment, a matching structure of the positioning posts and the positioning holes may be disposed between the fixing plate 11 and the first housing 200 to improve the connection stability therebetween. The present application does not strictly limit the connection structure between the fixing plate 11 of the first connection assembly 100 and the first housing 200.

As shown in fig. 23 to 25, the second end 162 of the first elastic member 16 is fixedly connected to the first housing 200.

Illustratively, the first housing 200 has a first post 22. The second end 162 of the first elastic member 16 may be hooked on the first boss 22 of the first housing 200.

As shown in fig. 23 to 25, the second end 1432 of the second elastic member 143 is fixedly coupled to the first housing 200.

Illustratively, the first housing 200 has a second post 23. The second end 1432 of the second elastic member 143 may be hooked on the second boss 23 of the first housing 200.

As shown in fig. 23 to 25, the stopper 17 is fixedly connected to the first housing 200.

Illustratively, the first housing 200 is provided with fastening holes. The stopper 17 may be locked to the first housing 200 by a fastener (screw, etc.).

Illustratively, the first housing 200 is provided with a through-hole 21. A portion of the stopper 17 may be located in the through hole 21 and not protrude outside the first housing 200 through the through hole 21.

As shown in fig. 23 to 25, the torsion spring 18 is fixedly coupled to the first housing 200.

Illustratively, the first housing 200 is provided with a stop post 25. The middle portion 182 of the torsion spring 18 may be locked to the stopper post 25 of the first housing 200 by a fastener (screw, etc.).

Illustratively, the first housing 200 is provided with a detent 24. A portion of the second end 183 of the torsion spring 18 may be disposed within the detent 24.

In one embodiment, the above-described assembly may be mounted on the fixing plate 11 when the area of the fixing plate 11 is sufficiently large, and the fixing plate 11 is assembled to the first housing 200. In this way, the assembly process of the first coupling assembly 100 and the first housing 200 can be simplified, so that the assembly is simpler.

In one embodiment, when the fixing plate 11 is not provided, the parts of the first connection assembly 100 connected to the fixing plate 11 may be directly connected to the first housing 200.

Fig. 26 is a schematic diagram of the structure of the partial display device 1000 shown in fig. 25 when the communication system 1 is in a connected state.

As shown in fig. 24 to 26, the first housing 200 is provided with a through hole 21. The through hole 21 communicates the inside with the outside of the first housing 200.

It will be appreciated that when the first portion 125 of the lever 12 overcomes the spring force of the torsion spring 18, the lever 12 may be rotated in a clockwise direction (illustrated in fig. 25 by the dashed line with an arrow). At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the negative direction of the Y axis relative to the fixed plate 11. At this time, a portion of the latch 13 protrudes to the outside of the first housing 200 through the through hole 21 of the first housing 200.

It will be appreciated that when the latch 13 is slidable in the positive X-axis direction relative to the fixed plate 11 under the tension of the first elastic member 16, the latch 13 is also slidable in the positive X-axis direction relative to the first housing 200 and within the through hole 21.

It will be appreciated that when the first portion 125 of the lever 12 is rotated in a counter-clockwise direction (illustrated in fig. 26 by the dashed line with the arrow) under the force of the torsion spring 18. At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the positive direction of the Y axis relative to the fixing plate 11. At this time, a portion of the latch 13 may protrude into the inside of the first housing 200 through the through hole 21 of the first housing 200.

In the present embodiment, the first connecting assembly 100 includes a stopper 17. A part of the stopper 17 is disposed in the first housing 200 provided with the through hole 21, and occupies the through hole 21. At this time, when the first rod portion 125 of the lever 12 can drive the latch 13 to slide along the negative direction of the Y axis relative to the fixing plate 11, a portion of the latch 13 protrudes to the outside of the first housing 200 through the limiting hole 171 of the limiting member 17. Although a portion of the latch 13 extends through the limiting hole 171 of the limiting member 17, the limiting member 17 is fitted into the through hole 21 of the first housing 200. Thus, a portion of the latch 13 is also equivalent to protruding to the outside of the first housing 200 through the through hole 21 of the first housing 200. Of course, in other embodiments, when the first connection assembly 100 does not include the stopper 17, a portion of the latch 13 may directly protrude to the outside of the first housing 200 through the through hole 21 of the first housing 200. Of course, in other embodiments, when the first connection assembly 100 includes the stopper 17, a portion of the stopper 17 is disposed within the through hole 21 provided in the first housing 200, but the stopper 17 does not occupy the through hole 21. At this time, a portion of the latch 13 may be protruded to the outside of the first housing 200 through the limiting hole 171 of the limiting member 17 and then through the through hole 21 of the first housing 200. But is also equivalent to a portion of the latch 13 protruding to the outside of the first housing 200 through the through hole 21 of the first housing 200 as a whole.

In the present embodiment, when the latch 13 is slidable in the positive direction of the X axis relative to the fixed plate 11 under the tensile force of the first elastic member 16, the latch 13 is also slidable in the positive direction of the X axis relative to the stopper 17 within the stopper hole 171.

In this embodiment, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the positive direction of the Y axis relative to the fixed plate 11. At this time, a portion of the latch 13 may protrude into the inside of the first housing 200 through the limiting hole 171 of the limiting member 17.

In the following description, a portion of the latch 13 is described as protruding to the outside of the first housing 200 through the stopper hole 171 of the stopper 17.

The structure of the first connection assembly 100 of the display device 1000 and the connection relationship between the first connection assembly 100 and the first housing 200 are specifically described above with reference to the accompanying drawings. The structure of the second connection assembly 300 of the input device 2000 and the connection relationship between the second connection assembly 300 and the second housing 400 will be described in detail with reference to the accompanying drawings.

Fig. 27 is a partially exploded view of the second connector assembly 300 shown in fig. 2.

As shown in fig. 27, the second connecting assembly 300 includes a detent 31, a third magnetic set 32, a fourth magnetic set 33, and a second detent 34.

Fig. 28 is a partial schematic structural view of the input device 2000 shown in fig. 1. Fig. 29 is a partial enlarged view of the partial input device 2000 shown in fig. 28 at A2. Fig. 30 is a cross-sectional view of a portion of the input device 2000 shown in fig. 29 at B1-B1.

As shown in fig. 27 to 30, the stopper 31 is fixedly connected to the second housing 400. For example, the stopper 31 may be fixedly coupled to the second housing 400 by bonding or welding.

Illustratively, a mating structure of the positioning post and the positioning hole may be further disposed between the positioning member 31 and the second housing 400 to improve the connection stability therebetween. The connection manner between the retainer 31 and the second housing 400 is not strictly limited in the present application.

In other embodiments, the detent 31 may be integrally formed with the second housing 400. In other embodiments, the second connecting assembly 300 may not be provided with the detent 31.

As shown in fig. 27 to 30, the stopper 31 is provided with a socket space 311. The plugging space 311 may be a jack or a slot. The plugging space 311 of the present embodiment is described by taking a jack as an example. It will be appreciated that the receptacles may be hole structures extending through the upper and lower surfaces of the catch 31. The slot may be a slot structure extending through the upper surface of the retainer 31, without extending through the lower surface. In addition, in other embodiments, when the second connection assembly 300 is not provided with the stopper 31, the plugging space 311 may be directly provided on the second housing 400. The plugging space 311 may be a jack or a slot. The mating space 311 may form an opening at an outer surface of the second housing 400.

In the present embodiment, the retainer 31 is fixed to the second housing 400 so that the retainer 31 may be a part of the second housing 400. Therefore, the insertion space 311 of the latch 31 may also be used as the insertion space of the second housing 400. The plugging space 311 corresponds to an opening formed on the outer surface of the second housing 400. When the positioning member 31 is provided with a slot, the slot can be used as a plugging space of the second housing 400. In the following description, the insertion space 311 of the retainer 31 is taken as an example of the insertion space of the second housing 400.

Illustratively, the mating space 311 includes a first space 3111 and a second space 3112. The first space 3111 communicates with the second space 3112. Wherein the second space 3112 is located at a peripheral side of the first space 3111. Thus, the wall surface of the second space 3112 may form a click surface 3113. In fig. 30, a first space 3111 and a second space 3112 are schematically distinguished by a broken line. Further, fig. 30 illustrates that the second space 3112 is disposed around the first space 3111. In other embodiments, the second space 3112 may be located at one side of the first space 3111.

As shown in fig. 27 to 30, the third magnetic group 32 is fixedly connected to the second housing 400.

Illustratively, the second housing 400 is provided with a first receiving groove 41. The third magnetic group 32 may be accommodated in the first accommodating groove 41.

For example, the structure of the third magnetic group 32 may be described with reference to the second magnetic group 15b (see fig. 21 and 22).

As shown in fig. 27 to 30, the fourth magnetic group 33 is fixedly coupled to the second housing 400.

Illustratively, the second housing 400 is provided with a second receiving groove 42. The fourth magnetic group 33 may be accommodated in the second accommodating groove 42.

For example, the structure of the fourth magnetic group 33 may be described with reference to the first magnetic group 15a (see fig. 21 and 22).

Fig. 31a is a schematic structural diagram of the first connection assembly 100 and the second connection assembly 300 shown in fig. 2 when the communication system 1 is in a connected state. Fig. 31b is a schematic structural diagram of the first connection assembly 100 and the second connection assembly 300 shown in fig. 2 when the communication system 1 is in a separated state.

As shown in fig. 31a, when the first magnetic group 15a and the third magnetic group 32 are close to each other, and the second magnetic group 15b and the fourth magnetic group 33 are close to each other, attractive force can be generated between the first magnetic group 15a and the third magnetic group 32, and repulsive force can be generated between the second magnetic group 15b and the fourth magnetic group 33. It will be appreciated that the attractive force may be generated between the first magnetic element 15a and the third magnetic element 32, and the repulsive force may be generated between the second magnetic element 15b and the fourth magnetic element 33 by the arrangement of the individual magnetic elements of the first magnetic element 15a and the arrangement of the individual magnetic elements of the third magnetic element 32.

As shown in fig. 31b, when the first magnetic group 15a and the third magnetic group 32 are away from each other, the second magnetic group 15b and the fourth magnetic group 33 are away from each other, the attractive force between the first magnetic group 15a and the third magnetic group 32 decreases, and the repulsive force between the second magnetic group 15b and the fourth magnetic group 33 decreases.

The connection process of the display device 1000 and the input device 2000 will be specifically described with reference to the above drawings.

As shown in fig. 3, when the user needs to use the communication system 1 in the connected state, that is, the communication system 1 is switched from the disconnected state illustrated in fig. 1 to the connected state illustrated in fig. 3, the display device 1000 may be disposed close to the input device 2000 first, and finally the display device 1000 is connected to the input device 2000. The display device 1000 may be positioned closer to the input device 2000 without moving the input device 2000, or the display device 1000 may be positioned without moving the input device 2000, or the display device 1000 may be moved with the input device 2000. The following description will be made by taking the example of moving the display device 1000 while the position of the input device 2000 is stationary.

As shown in fig. 31a and 31b, when the display device 1000 approaches the input device 2000, the limiting hole 171 of the limiting member 17 of the first connecting assembly 100 may be disposed opposite to the inserting space 311 of the positioning member 31 of the second connecting assembly 300. For example, the user may directly observe the positions of the limiting hole 171 of the limiting member 17 and the insertion space 311 of the positioning member 31, and then set the limiting hole 171 of the limiting member 17 opposite to the insertion space 311 of the positioning member 31. Thus, the first magnetic group 15a of the first link assembly 100 may be adjacent to the third magnetic group 32 of the second link assembly 300, and the second magnetic group 15b of the first link assembly 100 may be adjacent to the fourth magnetic group 33 of the second link assembly 300. Attractive force can be generated between the first magnetic group 15a and the third magnetic group 32, repulsive force can be generated between the second magnetic group 15b and the fourth magnetic group 33 as the distance is reduced, and repulsive force can be increased as the distance is reduced.

As shown in fig. 31a and 31b, when attractive force is generated between the first magnetic group 15a and the third magnetic group 32 and repulsive force is generated between the second magnetic group 15b and the fourth magnetic group 33, the attractive force and repulsive force may cause the second rod portion 126 of the lever 12 to receive a force in a positive direction of the Y-axis and the first rod portion 125 to receive a force in a negative direction of the Y-axis. When the attractive force between the first 15a and third 32 magnetic groups is sufficiently large and the repulsive force between the second 15b and fourth 33 magnetic groups is sufficiently large, the first portion 125 of the lever 12 may overcome the spring force of the torsion spring 18, such that the lever 12 may rotate in a clockwise direction (illustrated in fig. 31a by the dashed lines with arrows). At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the negative direction of the Y axis relative to the fixed plate 11. At this time, a part of the latch 13 extends out of the stopper 17 through the stopper hole 171 of the stopper 17 and into the insertion space 311 of the stopper 31. Reference is also made to the relevant description of fig. 11a, 11b and 8 regarding the movement relationship of the lever 12 and the latch 13. And in particular will not be described in detail herein.

Fig. 32 is a schematic view of a portion of the first connection assembly 100 and the second connection assembly 300 shown in fig. 31 a. Illustratively, fig. 32 illustrates an assembled schematic view between the latch 13 and the catch 31. Fig. 33 is a cross-sectional view of a portion of the first connection assembly 100 and the second connection assembly 300 shown in fig. 32 at B2-B2.

As shown in fig. 32 and 33, when a portion of the latch 13 extends into the insertion space 311 of the latch 31, a portion of the latch 13 may be inserted into the first space 3111 of the insertion space 311 in the negative direction of the Y axis and then snapped into the second space 3112 of the insertion space 311 in the positive direction of the X axis. At this time, a part of the latch 13 may be latched on the latching surface 3113 of the insertion space 311 of the latching piece 31. In this way, the display device 1000 can be stably connected to the input device 2000. In other words, the display device 1000 is not easily detached from the input device 2000.

It is understood that the process of inserting a portion of the latch 13 into the first space 3111 of the insertion space 311 in the negative direction of the Y axis may be performed by the above-mentioned sliding of the latch 13 in the negative direction of the Y axis by the lever 12. A process of inserting a portion of the latch 13 into the second space 3112 of the insertion space 311 in the positive direction of the X-axis is described below with reference to fig. 31a and 31 b.

As shown in fig. 31a and 31b, after a portion of the latch 13 is inserted into the first space 3111 of the insertion space 311 in the negative direction of the Y axis, the latch 13 can slide in the positive direction of the X axis with respect to the fixing plate 11 under the tensile force of the first elastic member 16. At this time, a part of the plug 13 is inserted into the second space 3112 of the insertion space 311 in the positive direction of the X axis. With respect to the connection relationship and movement pattern among the first elastic member 16, the latch 13 and the fixing plate 11, reference may be made to the related description of fig. 10, 11a and 11 b. And in particular will not be described in detail herein.

In other embodiments, the mating space 311 may not include the second space 3112. At this time, a portion of the latch 13 may be first inserted into the first space 3111 of the insertion space 311 in the negative direction of the Y axis.

The unlocking process of the display device 1000 and the input device 2000 is specifically described below with reference to the accompanying drawings.

As shown in fig. 1, when a user needs to use the communication system 1 in a separated state, that is, the communication system 1 is converted from the connected state illustrated in fig. 3 to the separated state illustrated in fig. 1, the communication system 1 may be unlocked first and finally the display device 1000 may be separated from the input device 2000.

The process of unlocking the communication system 1 is first described below. The method comprises the following steps:

as shown in fig. 31a and 31b, a user may input an energization instruction on the display device 1000 or the input device 2000. At this time, the SMA wire (i.e., the force application member 141) is energized, and the SMA wire generates a contraction force, and the SMA wire applies a force in the negative direction along the X-axis to the slider 142. The SMA wire may drive the slider 142 to slide in the negative X-axis direction with respect to the fixed plate 11. The sliding block 142 can drive the latch 13 to slide along the negative direction of the X axis. At this time, as shown in fig. 32 and 33, a part of the plug pin 13 can slide out from the second space 3112 of the insertion space 311 in the negative direction of the X axis.

In addition, the user may input a power-off instruction on the display device 1000 or the input device 2000. At this time, the SMA wire is powered off, and the second elastic member 143 may pull the slider 142 to slide along the positive direction of the X-axis, so that the slider 142 returns to the original position. The connection and movement between the force application member 141, the slider 142, the latch 13, the fixing plate 11, and the second elastic member 143 can be described with reference to fig. 16, 17a, and 17 b. And in particular will not be described in detail herein.

It will be appreciated that the power-on command or the power-off command may be input on the display device 1000 or the input device 2000 in several ways. In one embodiment, a mechanical key is provided on the display device 1000 or the input device 2000. When the user turns on the mechanical key, the power supply may energize the SMA wire. When the user turns off the mechanical key, the power supply does not power on the SMA wire, and the SMA wire is powered off. In one embodiment, a virtual key is provided on the UI interface of the display device 1000 or the input device 2000. When the user triggers the virtual key to open, the power supply can energize the SMA wire. When the user triggers the virtual key to close, the power supply does not power on the SMA wire, and the SMA wire is powered off.

The above describes the process of unlocking the communication system 1. The process of separating the display device 1000 from the input device 2000 is described again below. The method comprises the following steps:

As shown in fig. 32 and 33, after a portion of the latch 13 can slide out of the second space 3112 of the plugging space 311 along the negative direction of the X-axis, as shown in fig. 31a and 31b, the latch 13 of the first connection assembly 100 is no longer engaged with the catch 31 of the second connection assembly 300 in the X-axis direction. In this way, the display device 1000 can be pulled out from the input device 2000. During the process of pulling out the display device 1000 from the input device 2000, the display device 1000 is away from the input device 2000. At this time, the first magnetic group 15a and the third magnetic group 32 are away from each other, and the attractive force between the first magnetic group 15a and the third magnetic group 32 is reduced. The second magnetic group 15b and the fourth magnetic group 33 are separated from each other, and the repulsive force between the second magnetic group 15b and the fourth magnetic group 33 is reduced. The second rod portion 126 of the lever 12 receives a force in the positive direction along the Y-axis and the first rod portion 125 receives a force in the negative direction along the Y-axis, and the first rod portion 125 of the lever 12 is rotatable in the counterclockwise direction (indicated by the broken line with an arrow in fig. 31 b) under the elastic force of the torsion spring 18. At this time, the first rod portion 125 of the lever 12 may drive the latch 13 to slide along the positive direction of the Y axis. A portion of the latch 13 slides out of the insertion space 311 of the stopper 31 and protrudes into the interior of the first housing 200 through the stopper hole 171 of the stopper 17. In other embodiments, a portion of the latch 13 extends into the interior of the first housing 200 and a portion is positioned within the restraint aperture 171 of the restraint 17. As to the process of sliding the latch 13 in the positive direction of the Y-axis by the first rod portion 125 of the lever 12, reference is also made to the related description of fig. 21 and 22. And will not be described in detail here.

For example, the SMA wire energization time may be maintained for a period of time after the SMA wire (i.e., the force application member 141) is energized. For example 6 seconds, 7 seconds, 8 seconds, 9 seconds or 10 seconds, etc. This ensures that the user has enough time to pull the display device 1000 out of the input device 2000.

It will be appreciated that, in this embodiment, by disposing the latch 13 inside the first housing 200, enough space is left inside the second housing 400 of the input device 2000, and the space thus left can be used for disposing the rotation axis mechanism, so that when the display device 1000 is connected to the input device 2000, the display device 1000 can also rotate relative to the input device 2000 through the rotation axis mechanism, so as to adjust the angle of the display device 1000 relative to the input device 2000.

In other embodiments, the first connecting assembly 100 may not include the fixing plate 11, the lever 12, the restoring mechanism 14, the first magnetic set 15a, the second magnetic set 15b, the first elastic member 16, the limiting member 17, the torsion spring 18, and the like. The first coupling assembly 100 includes a drive mechanism. The driving mechanism may directly drive a portion of the latch 13 to protrude through the through hole 21 of the first housing 200 and be inserted into the insertion space 311 of the second housing 400.

In other embodiments, the first connecting assembly 100 may not include the fixing plate 11, the lever 12, the restoring mechanism 14, the first magnetic set 15a, the second magnetic set 15b, the first elastic member 16, the limiting member 17, the torsion spring 18, and the like. The first coupling assembly 100 includes only the latch 13. A user can directly drive a portion of the latch 13 by hand to protrude through the through hole 21 of the first housing 200 and insert into the insertion space 311 of the second housing 400.

As shown in fig. 31a and 31b, the first connection assembly 100 includes a first positioning member 19. The first positioning member 19 may be fixed to the first housing 200.

In one embodiment, the first positioning member 19 may be a magnetic member. The first positioning member 19 may be a single magnetic member or a magnetic group composed of a plurality of magnetic members. The first positioning member 19 of the present embodiment is described by taking a magnetic set as an example. Thus, in the present embodiment, the first positioning member 19 may also be referred to as a fifth magnetic group.

In addition, the second positioning member 34 may be a magnetic member. The second positioning member 34 may be a single magnetic member or a magnetic group of a plurality of magnetic members. The second positioning member 34 of the present embodiment is described by taking a magnetic set as an example. Thus, in the present embodiment, the second positioning member 34 may also be referred to as a sixth magnetic group.

In the present embodiment, the arrangement of the magnetic elements of the fifth magnetic group 19 can be referred to as the arrangement of the magnetic elements of the first magnetic group 15 a. In addition, the number of magnetic pieces of the fifth magnetic group 19 may be set to be larger than the number of magnetic pieces of the first magnetic group 15 a.

In the present embodiment, the arrangement of the magnetic elements of the sixth magnetic group 34 may refer to the arrangement of the magnetic elements of the third magnetic group 32. In addition, the number of magnetic pieces of the sixth magnetic group 34 may be set to be larger than the number of magnetic pieces of the third magnetic group 32.

It can be understood that when the display device 1000 is close to the input device 2000, the through hole 21 of the first housing 200 is disposed opposite to the opening of the plugging space 311 of the second housing 400 by the attractive force of the fifth magnetic group and the sixth magnetic group. In this way, after a part of the latch 13 protrudes through the limiting hole 171 of the limiting member 17, it can be accurately inserted into the insertion space 311 of the second housing 400.

In other embodiments, the first positioning member 19 and the second positioning member 34 may be pogo pin connectors or the like.

The first and second connection assemblies 100 and 300 of one construction are described in detail above in connection with the associated drawings. The second connection assembly 500 and the first connection assembly 600 of another structure will be described in detail with reference to the accompanying drawings. The following embodiments are similar to the embodiments described above, and the technical contents are not repeated.

Fig. 34 is a schematic view of the second connection assembly of fig. 2 in another embodiment. Fig. 35 is a partially exploded view of the second connection assembly shown in fig. 34. In the present embodiment, the second connection assembly 500 located at the right portion of the input device 2000 is described as an example.

As shown in fig. 34 and 35, the second connection assembly 500 includes a fixing plate 51, a slider 52, a latch 13, an elastic member 54, and a second magnetic group 55.

For convenience of description, exemplarily, a length direction of the fixing plate 51 is defined as an X-axis direction, a width direction of the fixing plate 51 is defined as a Y-axis direction, and a thickness direction of the fixing plate 51 is defined as a Z-axis direction. In the present embodiment, the positive direction of the Y axis is the first direction. The positive direction of the X-axis is the second direction. The negative direction of the X-axis is the third direction. The negative direction of the Y-axis is the fourth direction.

Thus, the first direction is different from the second direction. It will be appreciated that the coordinate system of the communication system 1 may also be flexibly set according to specific requirements. At this time, the first direction and the second direction can be flexibly set according to specific requirements.

As shown in fig. 35, the fixing plate 51 includes a main body portion 511 and an extension portion 512.

It will be appreciated that the securing plate 51 may be a unitary structure, i.e., the body portion 511 and the extension portion 512 are integrally formed. The fixing plate 51 may also be a spliced structure. For example, the body portion 511 and the extension portion 512 may be formed as a unitary structure by a splicing process (e.g., a mortise and tenon process) or a fastening process (e.g., a welding, bonding, etc.). The application is not particularly limited.

Illustratively, the body portion 511 includes a first face 5111 and a second face 5112 disposed opposite thereto. The extension 512 connects the first face 5111 of the main body 511.

Illustratively, the body portion 511 is provided with a sliding space 5113. The opening of the sliding space 5113 is located at the first face 5111 and the second face 5112 of the main body 511. The extending direction of the sliding space 5113 may be the X-axis direction.

Illustratively, the extension 512 includes a first portion 5121 and a second portion 5122. The first portion 5121 is connected between the main body 511 and the second portion 5122. The second portion 5122 is disposed opposite the main body 511. The extension portion 512 and the main portion 511 can enclose a space for movement.

Illustratively, the body portion 511 is also provided with a boss 5114. The boss 5114 is connected to the first face 5111 of the main body 511. In other embodiments, the boss 5114 can also be integrally formed with the body 511.

Fig. 36 is a schematic view of the slider 52 shown in fig. 35 at a different angle.

As shown in fig. 35 and 36, the slider 52 includes a bottom plate 521, a first bump 522, a second bump 523, and a third bump 524.

It is understood that the slider 52 may be a unitary structure, i.e., the bottom plate 521, the first bump 522, the second bump 523, and the third bump 524 are integrally formed. The slider 52 may also be a spliced structure. For example, the bottom plate 521, the first bump 522, the second bump 523, and the third bump 524 may be formed into a single integral structure by a splicing method (for example, a mortise and tenon process) or a fixing method (for example, a welding, bonding, etc. process). The application is not particularly limited.

Illustratively, the bottom plate 521 includes a first face 5211 and a second face 5212 disposed opposite thereto. The first bump 522 and the second bump 523 are connected to the first surface 5211 of the bottom plate 521 at intervals.

Illustratively, the first bump 522 has a first side 5221. The first side 5221 faces the second bump 523. The first side 5221 is beveled. The first side 5221 can also be referred to as a first angled surface. It will be appreciated that the bevel may be such that the first side 5221 is inclined to the vertical (i.e., YZ plane).

Illustratively, the second bump 523 has a second side 5231. The second side 5231 faces the first bump 522 and is disposed opposite the first side 5221 of the first bump 522. The second side 5231 is beveled. The second side 5231 can also be referred to as a second inclined surface. The bevel may be that the second side 5231 is inclined to the vertical (i.e., YZ plane).

Illustratively, the first side 5221 of the first bump 522 and the second side 5231 of the second bump 523 may be parallel.

Illustratively, the third bump 524 connects the second face 5212 of the bottom plate 521. At this time, the third bump 524 is disposed opposite to the first bump 522 and the second bump 523. The third bump 524 may have a bar shape.

Fig. 37 is a schematic view of a portion of the second connection assembly 500 shown in fig. 34 at another angle. Illustratively, fig. 37 illustrates an assembled schematic view between the fixed plate 51 and the slider 52. Fig. 38 is a partial structural schematic diagram of the second connection assembly 500 shown in fig. 34.

As shown in fig. 35 to 38, the slider 52 is slidably connected to the fixing plate 51.

Illustratively, the second face 5212 of the bottom plate 521 of the slider 52 is disposed opposite the first face 5111 of the body portion 511 of the fixed plate 51. The third protrusion 524 of the slider 52 may be positioned in the sliding space 5113 of the fixing plate 51. The third protrusion 524 may slide in the sliding space 5113. In the present embodiment, the slider 52 is slidable in the X-axis direction with respect to the fixed plate 51.

Fig. 39 is a partial structural schematic diagram of the second connection assembly 500 shown in fig. 34. Illustratively, fig. 39 illustrates a schematic view of the assembly of the fixed plate 51, the slider 52, the latch 13, and the elastic member 54.

As shown in fig. 39, the latch 13 is slidably connected to the slider 52. The latch 13 is also slidably coupled to the second portion 5122 of the extension 512 of the fixed plate 51.

Illustratively, latch 13 has third and fourth sides 531, 532 disposed opposite. The third side 531 and the fourth side 532 are beveled. The third side 531 and the fourth side 532 may each be inclined with respect to a vertical plane (i.e., YZ plane). The third side 531 may also be referred to as a third inclined surface. The fourth side 532 may also be referred to as a fourth inclined surface. Note that fig. 35 also illustrates the third side 531 and the fourth side 532 at different angles.

As shown in fig. 39, the third side 531 faces the first side 5221 of the slider 52. The fourth side 532 faces the second side 5231 of the slider 52. At this time, the third side 531 and the fourth side 532 are located between the first side 5221 and the second side 5231 of the slider 52.

As shown in fig. 39, a portion of the latch 13 may be located in a space surrounded by the body portion 511 and the extension portion 512 of the fixing plate 51.

Illustratively, an upper surface of the latch 13 may contact the second portion 5122 of the extension 512 of the fixed plate 51. The lower surface of the latch 13 may be in contact with the bottom plate 521 of the slider 52. Thus, the fixed plate 51 and the slider 52 can restrict the movement of the plug pin 13 in the Z-axis direction. In addition, the latch 13 may be provided with a recess 534 (fig. 35 illustrates the recess 534 by different angles). The opening of the recess 534 is located on the upper surface of the latch 13. A portion of the second portion 5122 of the extension 512 of the fixation plate 51 may be disposed within the groove 534. In the X-axis direction, the second portion 5122 of the extension 512 is in contact with the wall of the groove 534. At this time, the movement of the latch 13 in the X-axis direction can be restricted by the engagement of the second portion 5122 of the extension 512 with the groove 534.

It will be appreciated that when the slider 52 is subjected to a driving force in the negative direction of the X-axis, the slider 52 can move in the negative direction of the X-axis relative to the fixed plate 51. At this time, the first side 5221 of the slider 52 contacts the third side 531 of the latch 13. The slider 52 may apply a negative force to the peg 13 in the X-axis direction. In addition, since the first side 5221 and the third side 531 are inclined surfaces, the movement of the latch 13 in the X-axis direction is restricted, and the movement of the latch 13 in the Z-axis direction is restricted, the slider 52 can push the latch 13 to slide in the Y-axis forward direction.

As shown in fig. 39, the elastic member 54 connects the slider 52 and the fixing plate 51.

Illustratively, the resilient member 54 may be a spring. The resilient member 54 includes a first end 541 and a second end 542. The first end 541 of the elastic member 54 may be fixedly coupled to the first projection 522 of the slider 52. The second end 542 of the elastic member 54 may be fixedly coupled to the boss 5114 of the fixing plate 51. For example, the first protrusion 522 of the slider 52 is provided with a groove, and the first end 541 of the elastic member 54 may be hooked in the groove of the first protrusion 522. The second end 542 of the elastic member 54 may be hooked on the boss 5114 of the fixing plate 51.

It will be appreciated that when the slider 52 is driven in the negative direction of the X-axis, the slider 52 slides in the negative direction of the X-axis relative to the fixed plate 51, and the elastic member 54 is in a stretched state. At this time, when the slider 52 is no longer subjected to the driving force in the negative direction of the X-axis, since the elastic member 54 is in a stretched state, the elastic member 54 can apply an elastic force to the slider 52 in the positive direction of the X-axis, and the slider 52 moves in the positive direction of the X-axis with respect to the fixed plate 51 under the elastic force of the elastic member 54. At this time, the second side 5231 of the slider 52 contacts the fourth side 532 of the latch 13. The slider 52 can apply a force to the plug 13 in the positive direction along the X-axis. Since the second side 5231 and the fourth side 532 are inclined surfaces, the movement of the latch 13 in the X-axis direction is restricted, and the movement of the latch 13 in the Z-axis direction is restricted, the slider 52 can push the latch 13 to slide in the negative direction of the Y-axis.

In other embodiments, the second connection assembly 500 may not employ the elastic member 54. For example, replacing the elastic member 54 with an electromagnet or a motor, etc. The slider 52 is driven to slide relative to the fixed plate 51 by an electromagnet or an electrode.

In other embodiments, a reversing mechanism may be provided between the slider 52 and the latch 13, so that a driving force applied to the slider to slide in the X-axis direction is converted into a driving force in the Y-axis direction by the reversing mechanism, and the latch 13 is driven to move in the Y-axis direction by the driving force in the Y-axis direction.

The movement relationship of the slider 52 and the latch 13 of the second link assembly 500 is specifically described above, and a manner in which the slider 52 is driven to slide relative to the fixed plate 51 is specifically described below with reference to the accompanying drawings.

As shown in fig. 34, the second magnetic group 55 is fixed to the slider 52.

The second magnetic group 55 may be fixed to the first face 5211 of the slider 52 by bonding, welding, or the like, for example.

The second magnetic group 55 may be a magnetic group composed of a plurality of magnetic members, for example. In other embodiments, the second magnetic group 55 may be replaced with a single magnetic piece.

Fig. 40 is a partial schematic structural view of the input device 2000 shown in fig. 1. Illustratively, fig. 40 illustrates an assembled schematic view between the second connection assembly 500 and the second housing 400. Fig. 41 is a partial enlarged view of the partial input device 2000 shown in fig. 40 at A3.

As shown in fig. 40 and 41, the second housing 400 is provided with a through hole 401. The through hole 401 communicates the inside and the outside of the second housing 400.

Wherein the second connection assembly 500 is disposed on the second housing 400. Illustratively, the fixing plate 51 of the second coupling assembly 500 is fixedly coupled to the second housing 400. The fixing plate 51 is fixedly coupled to the second housing 400 by, for example, an adhesive process or a welding process. It is understood that the slider 52, the latch 13, the elastic member 54, and the second magnetic assembly 55 of the second connection assembly 500 may be assembled with the fixing plate 51 first. The fixing plate 51 is then assembled with the second housing 400. In this way, the assembly process of the present embodiment is simpler than the scheme of sequentially assembling the second connection assemblies 500 to the second housing 400, respectively.

In other embodiments, the fixing plate 51 may be formed integrally with the second housing 400.

In other embodiments, when the second connection assembly 500 does not include the fixing plate 51, other components of the second connection assembly 500 may be directly connected and mated with the second housing 400.

As shown in fig. 40 and 41, when the communication system 1 is in the separated state, all of the second connection assembly 500 may be located inside the second housing 400. Thus, the input device 2000 has better appearance consistency and better accords with the visual and aesthetic effects of human body. On the other hand, when the input device 2000 is externally impacted, the latch 13 is not easily deformed or even damaged by direct impact. The second connection assembly 500 has a longer life. It should be noted that, since all of the second connection assembly 500 may be located inside the second housing 400, fig. 40 and 41 illustrate the second connection assembly 500 by a dotted line.

As shown in fig. 40 and 41, when the slider 52 pushes the latch 13 to slide in the positive direction of the Y-axis, a portion of the latch 13 may protrude outside the second housing 400 through the through hole 401 of the second housing 400. When the slider 52 can push the latch 13 to slide in the negative direction of the Y-axis, a portion of the latch 13 can protrude into the outside of the second housing 400 through the through hole 401 of the second housing 400.

Fig. 42 is a schematic view of the first connection assembly of fig. 2 in another embodiment. Fig. 43 is a partially exploded view of the first connection assembly 600 shown in fig. 42.

As shown in fig. 42 and 43, the first connection assembly 600 includes a fixing plate 61, a latch 62, a force application member 63, a first elastic member 64, a spring door 65, and a first magnetic group 66.

Fig. 44 is a schematic view of the structure of the fixing plate 61 shown in fig. 43 at different angles.

As shown in fig. 43 and 44, the fixing plate 61 includes a main body portion 611, a click block 612, a first bar-shaped protrusion 613, a second bar-shaped protrusion 614, a first fixing block 615, a second fixing block 616, and a third fixing block 617.

It will be appreciated that the fixing plate 61 may be a unitary structure, i.e., the main body 611, the clamping block 612, the first bar-shaped protrusion 613, the second bar-shaped protrusion 614, the first fixing block 615, the second fixing block 616, and the third fixing block 617 are integrally formed. The fixing plate 61 may also be a spliced structure. For example, the body 611, the clamping block 612, the first bar-shaped protrusion 613, the second bar-shaped protrusion 614, the first fixing block 615, the second fixing block 616, and the third fixing block 617 may be formed into a single integral structure by a splicing method (for example, a mortise and tenon process) or a fixing method (for example, a welding, bonding, etc. process). The application is not particularly limited.

Illustratively, the body portion 611 includes a first face 6111 and a second face 6112 disposed opposite.

Illustratively, the detent block 612 may be attached to the first face 6111 of the body portion 611. In other embodiments, the locking piece 612 may be connected to the peripheral surface of the body 611.

Wherein the clamping block 612 has a jack 6121. In addition, the clamping block 612 is further provided with an avoidance groove 6122. The avoidance groove 6122 communicates with the insertion hole 6121.

Illustratively, the first and second bar-shaped protrusions 613, 614 may be attached to the first face 6111 at intervals. The first bar-shaped protrusion 613 is located at one side of the clamping block 612 and may face the escape groove 6122. The second bar-shaped protrusion 614 may be located at one side of the clamping block 612 and face the insertion hole 6121.

Illustratively, the first bar-shaped protrusion 613 extends at an angle to the second bar-shaped protrusion 614. For example, the first bar-shaped protrusion 613 may extend in the X-axis direction. The second bar-shaped protrusions 614 may extend in the Y-axis direction. At this time, the angle between the extending direction of the first bar-shaped protrusion 613 and the extending direction of the second bar-shaped protrusion 614 is 90 °.

Illustratively, the first, second, and third fixed blocks 615, 616, 617 may be coupled to the first face 6111 at intervals. The first fixing block 615 may be located at a side of the first bar-shaped protrusion 613 remote from the clamping block 612, i.e., the first bar-shaped protrusion 613 may be located between the clamping block 612 and the first fixing block 615. The second fixing block 616 may be located at a side of the clamping block 612 remote from the first bar-shaped protrusion 613, i.e., the clamping block 612 may be located between the first bar-shaped protrusion 613 and the second fixing block 616. The third fixing block 617 may be located at a side of the second bar-shaped protrusion 614 away from the clamping block 612, i.e., the second bar-shaped protrusion 614 may be located between the clamping block 612 and the third fixing block 617.

Fig. 45 is a schematic view of a portion of the structure of the first connection assembly 600 shown in fig. 42 at different angles. Illustratively, fig. 45 illustrates an assembled schematic view of the latch 62 and the elastic member 64 at different angles.

As shown in fig. 43 and 45, the latch 62 has a first face 621 and a second face 622 disposed opposite thereto, and a first side 623 and a second side 624 disposed opposite thereto. The first side 623 and the second side 624 are connected between the first face 621 and the second face 622.

Illustratively, the latch 62 is provided with a securing slot 625. The openings of the fixing groove 625 are located at the first and second sides 621 and 624 of the body portion 611. Further, a fixing post 6251 is provided in the fixing groove 625.

As shown in fig. 45, the latch 62 is provided with a first recess 626 and a second recess 627.

Illustratively, the opening of the first recess 626 is located at the second face 622, the first side 623, and the second side 624 of the latch 62.

Illustratively, the opening of the second recess 627 is located on the second face 622 and the second side 624 of the latch 62.

Fig. 46 is a partially exploded view of the first connector assembly 600 shown in fig. 42. Illustratively, fig. 46 illustrates an assembled schematic view between the fixing plate 61, the lock catch 62, the urging member 63, and the elastic member 64.

As shown in fig. 44 to 46, the lock catch 62 is slidably connected to the fixing plate 61.

Illustratively, the first bar-shaped protrusion 613 of the securing plate 61 may be located within the first groove 626 of the latch 62. Specifically, the groove wall of the first groove 626 of the locker 62 may slide with respect to the first bar-shaped protrusion 613 of the fixing plate 61.

It will be appreciated that the catch 62 may slide relative to the fixed plate 61 when the catch 62 is actuated. Illustratively, since the extending direction of the first bar-shaped protrusion 613 is the X-axis direction, the sliding direction of the latch 62 may be the X-axis direction. In addition, when the locker 62 slides in the X-axis direction with respect to the fixing plate 61, the locker 62 may be close to or away from the locking block 612. In addition, the locking bolt of the lock catch 62 may extend into the insertion hole 6121 through the avoidance groove 6122, or extend out of the insertion hole 6121 through the avoidance groove 6122.

As shown in fig. 44 to 46, the first elastic member 64 connects the fixing plate 61 and the latch 62.

The first elastic member 64 may be a spring, for example. In other embodiments, the first elastic member 64 may be a spring plate, rubber, torsion spring, or the like.

Illustratively, the first coupling assembly 600 further includes a fastener 642. The fasteners 642 may be rivets, screws, or the like. One end of the fastener 642 is fixedly coupled to the first fixing block 615 of the fixing plate 61. The other end of the fastener 642 is directed toward the catch 62. The first elastic member 64 is sleeved on the fastening member 642. One end of the first elastic member 64 may abut against the first fixing block 615 of the fixing plate 61, and the other end abuts against the lock catch 62.

Illustratively, a portion of the first resilient member 64 may be located within the second recess 627 of the latch 62. At this time, one end of the first elastic member 64 may abut against the groove wall of the second groove 627. Thus, the first elastic member 64 and the locker 62 have an overlapping area in the X-axis direction, and the length of the first connection assembly 600 in the X-axis direction can be reduced. In addition, the first elastic member 64 and the locker 62 have an overlapping area in the Z-axis direction, and the thickness of the first connection assembly 600 in the Z-axis direction can be reduced.

In one embodiment, the first resilient member 64 is in a compressed state when the communication system 1 is in a disconnected state. At this time, the first elastic member 64 may apply elastic force to the latch 62 when the communication system 1 is in the separated state. The lock catch 62 can extend into the insertion hole 6121 through the escape groove 6122 under the elastic force of the first elastic member 64.

In other embodiments, the first elastic member 64 may be in a natural state when the communication system 1 is in a separated state.

As shown in fig. 46, a portion of the urging member 63 is connected to the lock catch 62.

Illustratively, the force applying member 63 may be a shape memory alloy (shape memory alloy, SMA) wire, also referred to as a memory metal wire.

In one embodiment, the force application member 63 includes a first end 631, a middle 632, and a second end 633. The middle 632 of the force application member 63 is fixedly connected to the latch 62. One of the first end 631 and the second end 633 of the urging member 63 is electrically connected to a positive electrode of the power source, and the other is electrically connected to a negative electrode of the power source. The force application member 63 and the power supply may form a current loop.

Illustratively, a portion of the force application member 63 may be located within a securing slot 625 of the latch 62. The middle portion 632 of the force application member 63 can be fixedly coupled to the fixed post 6251 within the fixed slot 625.

In one embodiment, the SMA wire (i.e., the force application member 63) is not energized when the communication system 1 is in the disengaged state. At this point, the SMA wire may not apply a force to the latch 62.

It will be appreciated that when the communication system 1 transitions from the disconnected state to the connected state, the SMA wires are energized, which creates a contractive force, which may exert a force on the shackle 62 in the negative direction of the X-axis. At this time, the SMA wire may drive the latch 62 to slide along the negative direction of the X axis relative to the fixed plate 61. The latch 62 may be remote from the receptacle 6121 of the detent block 612. In addition, during the sliding of the latch 62 along the negative X-axis direction, the latch 62 may compress the first elastic member 64 such that the first elastic member 64 is in a compressed state. Thus, when the SMA wire is de-energized, the length of the SMA wire may be substantially restored to its original length. The SMA may not exert a pulling force on the latch 62 at this point. The latch 62 slides along the positive direction of the X axis relative to the fixed plate 61 under the elastic force of the first elastic member 64, and the latch tongue of the latch 62 can approach the insertion hole 6121 of the clamping block 612.

Fig. 47 is a schematic view of the spring door 65 shown in fig. 43 at different angles. Fig. 48 is a schematic view of the first connection assembly 600 shown in fig. 42 at a different angle.

As shown in fig. 47, the spring door 65 includes a door panel 651 and a second elastic member 652.

As shown in fig. 47 and 48, the door panel 651 is slidably coupled to the fixing plate 61.

Illustratively, the door panel 651 is provided with a first recess 6511. The second bar-shaped protrusion 614 (see fig. 46) of the fixing plate 61 may be located in the first groove 6511 of the spring door 65. Thus, when the door panel 651 is slid with respect to the fixing plate 61, the groove wall of the first groove 6511 of the door panel 651 can slide with respect to the second bar-shaped protrusion 614 of the fixing plate 61.

It is understood that the door panel 651 can slide with respect to the fixed plate 61 when the door panel 651 is driven. Illustratively, since the extending direction of the second bar-shaped projection 614 is the Y-axis direction, the sliding direction of the door panel 651 with respect to the fixing plate 61 is the Y-axis direction. In addition, when the door panel 651 can slide with respect to the fixing plate 61, the door panel 651 can be close to or away from the positioning block 612. In addition, a portion of the door panel 651 can extend into or out of the receptacle 6121.

As shown in fig. 47 and 48, the second elastic member 652 may be a spring. The number of the second elastic members 652 may be two. In other embodiments, the second elastic member 652 may be a spring plate, rubber, torsion spring, or the like. The number of the second elastic members 652 is not limited.

Illustratively, the spring door 65 also includes a fastener 6522. The fasteners 6522 may be rivets, screws, or the like. One end of the fastener 6522 is fixedly coupled to the third fixing block 617 of the fixing plate 61. The second elastic member 652 is sleeved on the fastening member 6522. A portion of the second elastic member 652 may be positioned within the second groove 6512 of the door panel 651. In this way, the second elastic member 652 has an overlapping area with the door panel 651 in the Y-axis direction, and the length of the first connection assembly 600 in the Y-axis direction can be reduced.

In one embodiment, the second elastic member 652 is in a compressed state when the communication system 1 is in a separated state. At this time, the second elastic member 652 may apply an elastic force to the door plate 651 when the communication system 1 is in the separated state. The door panel 651 is inserted into the insertion hole 6121 by the elastic force of the second elastic member 652. When the communication system 1 is in the separated state, the lock catch 62 presses the door panel 651 against the lock block 612 under the elastic force of the first elastic member 64. The friction force provided by the clamping block 612 can counteract the elastic force of the second elastic piece 652, and the door panel 651 cannot be pushed out of the insertion hole 6121 by the second elastic piece 652. In addition, when a portion of the door panel 651 is inserted into the insertion hole 6121, external dust or moisture or the like can be prevented from entering the first housing 200 from the insertion hole 6121 of the fixing plate 61.

In other embodiments, the second elastic member 652 is in a natural state when the communication system 1 is in a separated state. When the communication system 1 is in the separated state, a part of the door panel 651 protrudes into the insertion hole 6121. In addition, when the communication system 1 is in the separated state, the lock catch 62 presses the door panel 651 against the positioning block 612 under the elastic force of the first elastic member 64. The detent block 612 may provide friction to the door panel 651 so that the door panel 651 does not disengage the receptacle 6121.

In one embodiment, as shown in fig. 47 and 48, the door panel 651 is provided with notches 6513. The notch 6513 is located on the side of the door panel 651. At this time, the size of the portion of the door panel 651 that protrudes into the insertion hole 6121 in the X-axis direction is smaller than the size of the portion of the door panel 651 that does not protrude into the insertion hole 6121 in the X-axis direction. In this way, the wall surface of the notch 6513 of the door panel 651 can be abutted against the positioning block 612 of the fixing plate 61 by the elastic force of the second elastic member 652.

In other embodiments, the display device 1000 further includes a spacing mechanism (not shown). The limiting mechanism is used for limiting the door plate 651 in the Y-axis direction when the communication system 1 is in the separated state, so that the door plate 651 is prevented from being separated through the jack 6121. For example, the stopper mechanism may be a stopper (not shown) provided on the fixed plate 61. When the communication system 1 is in the separated state, the stopper abuts on the door plate 651 in the Y-axis direction. Illustratively, the stop block may be located at a position of the notch 6513 of the door panel 651.

As shown in fig. 48, the first magnetic group 66 is fixed to the fixed plate 61.

Illustratively, the first magnetic group 66 may be mounted between the body portion 611 of the fixed plate 61 and the second fixed block 616.

Illustratively, the first magnetic group 66 may be bonded to the first face 6111 of the fixed plate 61 and the side face of the second fixed block 616.

Fig. 49 is a schematic view of a part of the structure of the display device 1000 shown in fig. 1. Illustratively, fig. 49 illustrates a schematic view of the first coupling assembly 600 assembled with the first housing 200. Fig. 50 is a partial enlarged view of the portion display device 1000 shown in fig. 49 at A4.

As shown in fig. 49 and 50, the first connection assembly 600 is provided on the first housing 200. Illustratively, the fixing plate 61 of the first coupling assembly 600 is fixedly coupled to the first housing 200. The second face 6112 of the fixing plate 61 is fixedly attached to the first housing 200 by, for example, an adhesive process or a welding process. It is understood that the latch 62, the force applying member 63, the first elastic member 64, the spring door 65, and the first magnetic assembly 66 of the first connection assembly 600 may be assembled with the fixing plate 61. The fixing plate 61 is then assembled with the first housing 200. In this way, the assembly process of the present embodiment is simpler than the scheme of sequentially assembling the first coupling assemblies 600 to the first housing 200, respectively.

In other embodiments, the fixing plate 61 may be formed integrally with the first housing 200.

In other embodiments, when the first connection assembly 600 does not include the fixing plate 61, other components of the first connection assembly 600 may be directly engaged with the first housing 200.

In one embodiment, when the communication system 1 is in a disconnected state, all of the first connection assembly 600 is located within the first housing 200. Thus, the display device 1000 has better appearance consistency and better accords with the visual and aesthetic effects of human body. On the other hand, when the display device 1000 is externally impacted, the components within the first connection assembly 600 are not easily deformed or even damaged by direct impact.

As shown in fig. 50, at least part of the positioning block 612 of the fixing plate 61 is located in the through hole 21 of the first housing 200. The detent block 612 is provided with a receptacle 6121. The insertion hole 6121 can be used as a plugging space for the detent block 612. In other embodiments, the detent block 612 may also be provided with a slot. The slot may serve as a socket space for the detent block 612. In addition, in other embodiments, when the first connection assembly 600 is not provided with the clamping block 612, a plugging space may be directly provided on the first housing 200. The plugging space can be a jack or a slot.

In the present embodiment, the positioning block 612 is fixed to the first housing 200 so that the positioning block 612 may be a part of the first housing 200. Thus, the insertion hole 6121 of the locking block 612 may also be used as a plugging space of the first housing 200. When the positioning block 612 is provided with a slot, the slot can be used as a plugging space of the first housing 200. In the following description, the insertion hole 6121 of the lock block 612 is taken as an example of the insertion space of the first housing 200.

In other embodiments, the position of the first connection assembly 600 of the present embodiment may be reversed from the position of the second connection assembly 500. At this time, the display device 1000 of the present embodiment includes the structure of the second connection assembly 500. The input device 2000 of the present embodiment includes a structure of the first connection assembly 600. At this time, when the user needs to use the communication system 1 in the connected state, that is, the communication system 1 is converted from the separated state illustrated in fig. 1 to the connected state illustrated in fig. 3, the latch 13 of the second connection assembly 500 of the display device 1000 may be protruded through the through hole 21 provided in the first housing 200 and inserted into the insertion hole 6121 of the latching block 612 of the input device 2000.

The specific structure of the first and second connection assemblies 600 and 500 is described above, and the connection and disconnection process between the first and second connection assemblies 600 and 500 is described below with reference to the accompanying drawings.

Fig. 51 is a partial schematic structural view of the communication system 1 shown in fig. 3 in another embodiment.

As shown in fig. 51, the first magnetic group 66 illustratively includes a first magnet 661, a second magnet 662, and a third magnet 663. The first magnet 661 and the third magnet 663 have the same magnetic force direction and the opposite magnetic force direction to the second magnet 662. The second magnet 662 is located intermediate the first magnet 661 and the third magnet 663.

Illustratively, the second magnetic group 55 includes a first magnet 551, a second magnet 552, and a third magnet 553. The first magnet 551 and the third magnet 553 have the same magnetic force direction and the opposite magnetic force direction as the second magnet 552. The second magnet 552 is positioned intermediate the first magnet 551 and the third magnet 553.

It will be appreciated that the polarity of the end of the first magnet 661 of the first magnetic group 66 adjacent to the first magnet 551 of the second magnetic group 55 is opposite to the polarity of the end of the first magnet 551 of the second magnetic group 55 adjacent to the first magnet 661 of the first magnetic group 66, i.e. an attractive force may be generated between the first magnet 661 of the first magnetic group 66 and the first magnet 551 of the second magnetic group 55. Similarly, the attractive force is generated between the second magnet 662 of the first magnetic group 66 and the second magnet 552 of the second magnetic group 55 by the arrangement of the polarity of the second magnet 662 of the first magnetic group 66 and the arrangement of the polarity of the second magnet 552 of the second magnetic group 55. Further, by the polarity arrangement of the third magnet 663 of the first magnetic group 66 and the polarity arrangement of the third magnet 553 of the second magnetic group 55, an attractive force is generated between the third magnet 663 of the first magnetic group 66 and the third magnet 553 of the second magnetic group 55.

In one embodiment, the first magnetic group 66 is offset from the second magnetic group 55 in the X-axis direction. Thus, when the first connection assembly 600 and the second connection assembly 500 are close to each other, and the through hole of the first housing 200 is disposed opposite to the opening of the plugging space of the second housing 400, the first magnet 661 of the first magnetic group 66 will attract each other with the first magnet 551 of the second magnetic group 55, the second magnet 662 of the first magnetic group 66 will attract each other with the second magnet 552 of the second magnetic group 55, and the third magnet 663 of the first magnetic group 66 will attract each other with the third magnet 553 of the second magnetic group 55. At this time, since the first magnetic group 66 and the second magnetic group 55 are disposed offset in the X-axis direction, the first magnet 551 of the second magnetic group 55 receives the attractive force of the first magnet 661 of the first magnetic group 66 in the X-axis direction, the second magnet 552 of the second magnetic group 55 receives the attractive force of the second magnet 662 of the first magnetic group 66 in the X-axis direction, and the third magnet 553 of the second magnetic group 55 receives the attractive force of the third magnet 663 of the first magnetic group 66 in the X-axis direction. In other words, the second magnetic group 55 may receive the attractive force of the first magnetic group 66 in the X-axis direction. Thus, the second magnetic group 55 can drive the slider 51 to slide along the X-axis direction. For example, when the first magnetic group 66 and the second magnetic group 55 are disposed in a staggered manner in the negative X-axis direction, that is, in the negative X-axis direction, the first magnetic group 66 extends out relative to the second magnetic group 55, the second magnetic group 55 may drive the slider 51 to slide along the negative X-axis direction.

Illustratively, the first magnet 661 of the first magnetic group 66 includes a first side 6611 and a second side 6612. The first side 6611 is coupled to the second magnet 662 of the first magnetic group 66. The second side 6612 is a surface of the first magnet 661 facing away from the second magnet 662. In addition, the first magnet 551 of the second magnetic group 55 includes an end face 5511. The end surface 5511 is a surface of the first magnet 551 facing away from the second magnet 552.

In addition, the distance between the plane of the end surface 5511 and the plane of the second side surface 6612 is a. The distance between the plane of the end face 5511 and the plane of the first side face 6611 is b. Wherein a and b satisfy a: b < 1. In this way, the slider 52 can be driven to slide along the negative direction of the X-axis relative to the fixed plate 51 by the attractive force between the first magnetic group 66 of the first connecting assembly 600 and the second magnetic group 55 of the second connecting assembly 500. Illustratively, a: b=1:2.

It is understood that the first magnetic group 66 and the second magnetic group 55 of the present embodiment may constitute the driving mechanism of the present embodiment. In other embodiments, the second magnetic group 55 may be a member that can generate driving force, such as an electromagnet or a motor.

In this embodiment, the first connection assembly 600 may also include a first positioning member (not shown). The second connection assembly 500 may also include a second positioning member (not shown). The first positioning element and the second positioning element can be both referred to the arrangement modes of the first positioning element and the second positioning element in the above embodiment (refer to fig. 31a and 31 b). And in particular will not be described in detail herein.

It can be appreciated that when the display device 1000 approaches the input device 2000, the insertion hole 6121 of the clamping block 612 can be disposed opposite to the through hole 401 of the second housing 400 by positioning between the first positioning member and the second positioning member. Thus, on the one hand, the first magnetic group 66 and the second magnetic group 55 may be arranged in a staggered manner in the X-axis direction, so that the second magnetic group 55 may receive the attractive force of the first magnetic group 66 along the X-axis direction; on the other hand, after a part of the latch 13 protrudes through the through hole 401 of the second housing 400, it is advantageous that the latch can be accurately inserted into the insertion hole 6121 of the latching block 612.

Fig. 52 is a schematic structural diagram of the second connecting assembly 500 and the first connecting assembly 600 shown in fig. 51 in a connected state.

As shown in fig. 52, when the first connection unit 600 and the second connection unit 500 are connected to each other, the first magnet 661 of the first magnetic group 66 is disposed opposite to the first magnet 551 of the second magnetic group 55, the second magnet 662 of the first magnetic group 66 is disposed opposite to the second magnet 552 of the second magnetic group 55, and the third magnet 663 of the first magnetic group 66 is disposed opposite to the third magnet 553 of the second magnetic group 55.

The connection process of the display device 1000 and the input device 2000 will be described in detail with reference to the accompanying drawings.

As shown in fig. 51, when the display device 1000 approaches the input device 2000, the insertion hole 6121 of the clamping block 612 of the first connection assembly 600 may be disposed opposite to the through hole 401 of the second housing 400. Illustratively, the user may directly observe the positions of the insertion hole 6121 of the clamping block 612 and the through hole 401 of the second housing 400, and then dispose the insertion hole 6121 of the clamping block 612 opposite to the through hole 401 of the second housing 400. In this way, attractive force is generated between the first magnetic group 66 and the second magnetic group 55, and the attractive force gradually increases. Since the first magnetic group 66 and the second magnetic group 55 are staggered in the X-axis direction, the second magnetic group 55 can receive the attractive force of the first magnetic group 66 along the X-axis direction. The attractive force between the second magnetic set 55 and the first magnetic set 66 will drive the slider 52 to slide along the negative X-axis direction relative to the fixed plate 51. The latch 13 slides in the positive direction of the Y axis by the pushing of the slider 52. At this time, the latch 13 protrudes through the through hole 401 of the second housing 400 and is inserted into the insertion hole 6121 of the click block 612. With respect to the movement relationship of the latch 13 and the slider 52, reference is made to fig. 39. And in particular will not be described in detail herein.

Fig. 53 is an enlarged schematic view of a portion of the structure of the first and second connection assemblies 600 and 500 shown in fig. 52 at A4. Illustratively, fig. 53 illustrates a schematic structural view of the shackle 62 and the plug 13 when the communication system is in a connected state.

As shown in fig. 51 to 53, when a part of the latch 13 is inserted into the insertion hole 6121 of the click block 612, the latch 13 is in contact with the door panel 651 of the spring door 65. As a portion of the latch 13 continues to be inserted into the insertion hole 6121 of the detent block 612, the latch 13 may push the door panel 651 to slide in the positive Y-axis direction until the catch 62 is separated from the door panel 651. Thus, the first elastic member 64 in a compressed state can exert an elastic force in the positive direction of the X-axis on the latch 62. The lock catch 62 is slidable relative to the fixed plate 61 in the positive direction of the X axis under elastic force. The deadbolt of the shackle 62 can bear against the bolt 13 and lock the bolt 13. It will be appreciated that when a portion of the latch 13 is inserted into the insertion hole 6121 of the latch block 612, the latch 13 is pressed by the lock catch 62, and the connection between the latch 13 and the latch block 612 is more stable, that is, the connection between the display device 1000 and the input device 2000 is more stable.

In addition, since the latch 13 can push the door panel 651 to slide in the positive direction of the Y-axis as a portion of the latch 13 continues to be inserted into the insertion hole 6121 of the detent block 612, the second elastic member 652 of the spring door 65 is in a compressed state.

As shown in fig. 51 to 53, a user may input an energization instruction on the display device 1000 or the input device 2000. The SMA wire (i.e., the force application member 63) is energized and the SMA wire contracts. The SMA wire pulls the latch 62 to slide in the negative direction of the X-axis. At this time, the dead bolt of the lock catch 62 is separated from the plug pin 13, and extends out of the insertion hole 6121 through the escape groove 6122. The latch 13 is no longer pressed by the lock catch 62 in the positive direction of the X-axis, and the latch 13 can be pulled out from the insertion hole 6121 of the lock block 612. The movement of the lock catch 62 and the urging member 63 can be described with reference to fig. 46. And in particular will not be described in detail herein.

Thus, since the latch 13 is no longer pressed in the positive direction of the X-axis by the locker 62, the latch 13 can be pulled out from the insertion hole 6121 of the locking block 612, that is, the display device 1000 can be pulled out from the input device 2000. During the process of pulling out the display device 1000 from the input device 2000, the display device 1000 is away from the input device 2000. At this time, the first magnetic group 55 and the second magnetic group 66 are away from each other, and the attractive force between the first magnetic group 55 and the second magnetic group 66 decreases. The slider 52 pulls the latch 13 to slide in the positive direction of the X-axis under the elastic force of the elastic member 54 in a compressed state. Since the second side 5231 and the fourth side 532 are inclined surfaces, the movement of the latch 13 in the X-axis direction is restricted, and the movement of the latch 13 in the Z-axis direction is restricted, the slider 52 can push the latch 13 to slide in the negative direction of the Y-axis. Thus, the latch 13 may extend into the inside of the second housing 400 through the through hole 401 of the second housing 400. The process of inserting the latch 13 into the interior of the second housing 400 through the through hole 401 of the second housing 400 can be described with reference to fig. 39. And in particular will not be described in detail herein.

In addition, the door panel 651 of the spring door 65 slides with respect to the fixing plate 61 in the negative direction of the Y-axis by the elastic force of the second elastic member 652, and a portion of the door panel 651 may be protruded into the insertion hole 6121. In addition, during the sliding of the latch 62 along the negative X-axis direction, the latch 62 may compress the first elastic member 64 such that the first elastic member 64 is in a compressed state. Thus, when the SMA wire is de-energized, the length of the SMA wire may return to approximately the original state and the SMA wire may not exert a pulling force on the latch 62. The latch 62 slides in the positive direction of the X axis with respect to the fixing plate 61 under the elastic force of the first elastic member 64. The lock catch 62 may be close to the positioning block 612, and the lock tongue of the lock catch 62 may extend into the insertion hole 6121 through the avoidance groove 6122 and abut against the door panel 651. Reference is made to the description of fig. 46 for the process of the latch 62 extending into the receptacle 6121 through the relief slot 6122. And in particular will not be described in detail herein.

In other embodiments, the first connection assembly 600 may not include the spring gate 65. At this time, the latch 62 may be inserted into the insertion hole 6121 and shield the insertion hole 6121. In addition, the catches 62 that extend into the receptacles 6121 may be provided with an inclined surface. The latch 13 may be provided with an inclined surface. When the latch 13 is inserted into the jack 6121, the latch 13 can push a part of the lock catch 62 out of the jack 6121 through the cooperation of the inclined surfaces of the latch 13 and the jack 6121, so that a part of the lock catch 62 can be completely inserted into the jack 6121.

Several arrangements of the first connection assembly and the second connection assembly are specifically described above in connection with the associated drawings. Several arrangements of the second connection assembly will be described in detail below with reference to the accompanying drawings.

Fig. 54 is a schematic structural diagram of the first connection assembly 100 and the second connection assembly 300 shown in fig. 2 in another embodiment.

In the technical solution of the present embodiment, the technical content that is the same as that of the second embodiment is not described in detail. For example, the display device 1000 includes a first connection assembly 600. The first connecting assembly 600 may be disposed in the manner described in the second embodiment of the first connecting assembly 600. For example, the first connection assembly 600 includes a fixing plate 61, a latch 62, a force application member 63, a first elastic member 64, a spring door 65, a first magnetic group 66, and the like. And in particular will not be described in detail herein.

As shown in fig. 54, the second connection assembly 700 includes a fixing plate 71, a slider 72, a latch 13, an elastic member 74, and a second magnetic group 75.

Illustratively, a slider 72 is slidably coupled to the stationary plate 71. The connection between the slider 72 and the fixing plate 71 can be referred to as the connection between the slider 52 and the fixing plate 51 in the second embodiment. Illustratively, the slider 72 is slidable in the X-axis direction relative to the fixed plate 71.

Illustratively, the second magnetic group 75 is fixedly coupled to the slider 72. The arrangement of the second magnetic group 75, the connection between the second magnetic group 75 and the slider 72, and the action relationship between the second magnetic group 75 and the first magnetic group 66 can be referred to as the arrangement of the second magnetic group 55, the connection between the second magnetic group 55 and the slider 52, and the action relationship between the second magnetic group 66 and the first magnetic group 55 in the second embodiment. And in particular will not be described in detail herein.

As shown in fig. 54, the plug 13 includes a connection portion 731 and a hook portion 732. The hook 732 is connected to the connection 731. It will be appreciated that the latch 13 may be a unitary structure, i.e., the attachment portion 731 and the hook portion 732 are integrally formed. The latch 13 may also be a spliced structure. For example, the connection portion 731 and the hook portion 732 may be formed as a single integral structure by splicing (e.g., mortise and tenon processes) or fixing (e.g., welding, bonding, etc.). The application is not particularly limited.

Wherein the connection part 731 of the latch 13 is rotatably connected to the fixing plate 71. For example, the connection portion 731 of the latch 13 may be rotatably connected to the fixing plate 71 through a rotation shaft. In other embodiments, the rotation manner of the connection part 731 and the fixing plate 71 is not particularly limited.

In addition, the hook 732 of the latch 13 is elastically coupled to the fixing plate 71. For example, the hook 732 of the latch 13 may be connected to the fixing plate 71 by the elastic member 74. At this time, one end of the elastic member 74 is fixedly connected to the hook 732, and the other end is fixedly connected to the fixing plate 71. The elastic member 74 may be a torsion spring. In other embodiments, the elastic member 74 may be a spring plate, rubber, or a spring.

It will be appreciated that when slider 72 slides in the negative X-axis direction relative to fixed plate 71, slider 72 may apply a force to connection 731 of latch 13 to rotate connection 731 of latch 13 relative to fixed plate 71. At this time, the latch 13 may pull the elastic member 74 to put the elastic member 74 in a stretched state.

Illustratively, the connection 731 of the latch 13 is spaced from and opposite the slider 72 when the communication system 1 is in the disengaged state. In other embodiments, the connection portion 731 of the latch 13 may also be disposed in contact with the slider 72 when the communication system is in a disconnected state.

As shown in fig. 54, the second connection assembly 700 is disposed in the second housing 400. The connection manner of the second connection assembly 700 and the second housing 400 may refer to the connection manner of the second connection assembly 500 and the second housing 400 in the second embodiment. And in particular will not be described in detail herein.

Fig. 55 is a schematic structural diagram of the first connecting assembly 600 and the second connecting assembly 700 shown in fig. 54 in a connected state.

Referring to fig. 54 and 55, as shown in fig. 51, when the display device 1000 approaches the input device 2000, the insertion hole 6121 of the first connection assembly 600 may be disposed opposite to the through hole 401 of the second housing 400. In this way, attractive force is generated between the first magnetic group 66 and the second magnetic group 75, and the attractive force gradually increases. Because the first magnetic group 66 and the second magnetic group 75 are staggered in the X-axis direction, the attractive force between the second magnetic group 75 and the first magnetic group 66 drives the slider 72 to slide along the negative X-axis direction relative to the fixed plate 71. The latch 13 is rotated in a clockwise direction by the pushing of the slider 72. At this time, the hook 732 of the latch 13 protrudes through the through hole 401 of the second housing 400 and is inserted into the insertion hole 6121. See above for relevant matters in fig. 39 regarding the movement relationship of the latch 13 and the slider 72. And in particular will not be described in detail herein.

As shown in fig. 51 to 53, when the hook 732 of the latch 13 is inserted into the insertion hole 6121, the dead bolt of the lock catch 62 can be abutted against the latch 13. It will be appreciated that when a portion of the latch 13 is inserted into the receptacle 6121, the latch 13 is pressed by the catch 62, and the connection of the display device 1000 to the input device 2000 is more stable. After the hook 732 of the latch 13 is inserted into the insertion hole 6121, the movement of the door panel 651 and the lock catch 62 of the first connecting assembly 600 can be referred to the movement of the door panel 651 and the lock catch 62 of the first connecting assembly 600 of the second embodiment. And in particular will not be described in detail herein.

In addition, as a portion of the latch 13 continues to be inserted into the insertion hole 6121, the latch 13 may push the door panel 651 to slide in the positive Y-axis direction, with the second elastic member 652 of the spring door 65 being in a compressed state.

In addition, the elastic member 74 is in a stretched state when a part of the plug 13 is continuously inserted into the insertion hole 6121.

As shown in fig. 51 to 53, a user may input an energization instruction on the display device 1000 or the input device 2000. The SMA wire (i.e., the force application member 63) is energized and the SMA wire contracts. The SMA wire pulls the latch 62 to slide in the negative direction of the X-axis. At this time, the deadbolt of the shackle 62 is separated from the plug 13. Latch 13 may be pulled out of receptacle 6121. The movement of the lock catch 62 and the urging member 63 can be described with reference to fig. 46. And in particular will not be described in detail herein.

Thus, the latch 13 can be pulled out of the insertion hole 6121, that is, the display device 1000 can be pulled out of the input device 2000. During the process of pulling out the display device 1000 from the input device 2000, the display device 1000 is away from the input device 2000. At this time, the first magnetic group 75 and the second magnetic group 66 are away from each other, and the attractive force between the first magnetic group 75 and the second magnetic group 66 decreases. At this time, the latch 13 rotates in the counterclockwise direction under the tensile force of the elastic member 74. Thus, the latch 13 may extend into the inside of the second housing 400 through the through hole 401 of the second housing 400. In addition, the slider 72 may slide relative to the fixed plate 71 and may slide to the original position under the elastic force of an elastic member (not shown, and referring to the elastic member 54 of the second embodiment). The process of inserting the latch 13 into the interior of the second housing 400 through the through hole 401 of the second housing 400 can be described with reference to fig. 39. And in particular will not be described in detail herein.

In addition, the door panel 651 of the spring door 65 slides with respect to the fixing plate 61 in the negative direction of the Y-axis by the elastic force of the second elastic member 652, and a portion of the door panel 651 may extend into the insertion hole 6121. In addition, when the SMA wire is de-energized, the lock catch 62 slides in the positive direction of the X-axis relative to the fixed plate 61 under the elastic force of the first elastic member 64. The locking tongue of the shackle 62 may extend into the receptacle 6121 and rest against the door panel 651. See the description of fig. 46 for a process of extending the latch 62 into the receptacle 6121. And in particular will not be described in detail herein.
