Referring to fig. 1a, fig. 1a is a schematic diagram illustrating an electronic device in an open state.

As shown in fig. 1a, the electronic apparatus 100 'includes a foldable stand, and a main body 2' and an input device 3 'provided to the foldable stand, wherein the foldable stand includes a first body 10' for providing the input device 3 'and a second body 20' for supporting the main body 2', and the first body 10' and the second body 20 'are rotatably connected through a connection shaft 30'. When the foldable stand of the electronic device 100' is in the open state, the foldable standFrameThe second body 20 'of the first body 10' can support the host 2 'towards the user, and at the same time, in order to avoid interference between the input device 3' on the first body 10 'and the host 2' to affect normal use of the input device 3 'by the user, a larger space d' is left between the input device 3 'on the first body 10' and the connecting shaft 30', and the space where the input device 3' is disposed on the first body 10 'is reduced (as represented by the area M' shown in fig. 1 a), which affects the input experience of the user.

In order to make the first body 10' of the foldable stand have enough space to set the input device 3', it is common to increase the size of the first body 10' in such a way that the space of the first body 10' to set the input device 3' is increased, and the support stability and reliability of the foldable stand in the opened state are improved. However, the size of the first body 10' of the foldable stand is increased by adopting the technical scheme, so that the size and the volume of the foldable stand in the folded state are increased, the weight is heavy, and the portability of the foldable stand is affected. That is, it is difficult to combine the stowability and portability of the stand in the folded state with the support stability and reliability of the stand in the unfolded state when supporting the multi-device.

In order to solve the above-mentioned problem, the present application proposes an electronic device, by setting the first main body of the foldable stand to a telescopic structure, thereby making it possible to consider the storability and portability of the foldable stand in the folded state, and the foldable stand has a sufficient space for setting the input device in the unfolded state, and the supporting stability and reliability of the foldable stand are ensured.

The structure of the foldable stand, the input device, and the electronic device provided in the present application will be described in detail with reference to fig. 1b to 21 c.

Referring to fig. 1b, fig. 2 and fig. 3, fig. 1b is a schematic diagram of an electronic device in an open state according to an embodiment of the present application, fig. 2 is a schematic diagram of a structure of the electronic device in the open state according to an embodiment of the present application, and fig. 3 is a schematic diagram of the electronic device in a folded state according to an embodiment of the present application.

As shown in fig. 1b, 2 and 3, an embodiment of the present application provides an electronic device 100, which includes a foldable stand 1, and a host 2 and an input device 3 disposed on the foldable stand 1. Wherein the foldable stand 1 comprises a first body 10 and a second body 20 for supporting an object to be supported, the first body 10 being rotatably connected to the second body 20 about a first axis a such that the foldable stand 1 is switchable between an open state and a folded state. The main body 2 is provided as an object to be supported on the second main body 20.

When the foldable stand 1 is in the open state, the foldable stand 1 can support the host 2 and the input device 3 so that the relative positions of the host 2 and the input device 3 remain fixed, thereby facilitating the user to operate the host 2 and the input device 3. At this time, the space between the input device 3 and the connecting shaft 30 on the first body 10 is d, and the space where the input device 3 is disposed is m+l, which greatly increases the space where the input device 3 is disposed on the first body 10.

When the foldable stand 1 is in the folded state, the foldable stand 1 can support the host 2 and the input device 3 such that the host 2 and the input device 3 are stacked on each other, thereby reducing the space occupation of the entire electronic apparatus 100 to facilitate storage and carrying of the electronic apparatus 100. At the same time, the foldable stand 1 can play a protective role to prevent the main body 2 and the input device 3 from being damaged by external impact force, such as falling, pressing, etc.

In one embodiment, the first body 10 and the second body 20 are rotatably connected by a connection shaft 30, and the axis of the connection shaft 30 is a first axis a. Further, the first body 10 and the second body 20 are connected by damping rotation, so that the first body 10 and the second body 20 can relatively rotate to any angle and keep fixed, and when the first body 10 and the second body 20 rotate oppositely and the foldable stand 1 is in an open state, the first body 10 can be stably placed on the surface of other objects, such as a table top, a table top and the like. Meanwhile, the second body 20 can stably support the main body 2 and support the main body 2 above the first body 10, so that a user can directly operate the main body 2 or manipulate the main body 2 through the input device 3 on the foldable stand 1.

Further, the first body 10 is formed with a supporting surface when placed on a surface of another object. The second body 20 can support the main body 2 such that the center of gravity of the main body 2 falls within the support surface formed by the first body 10, thereby ensuring that the foldable stand 1 can stably support the main body 2 in the opened state.

In other alternative embodiments, other rotational connections between the first body 10 and the second body 20 may be used, such as a hinged connection, a gear connection, etc.

In one embodiment, the first body 10 and the second body 20 have a rotatable angle therebetween, and the first body 10 and the second body 20 may be relatively rotated in a range of 0 to 180 °. In other alternative embodiments, the rotation angle between the first body 10 and the second body 20 is not limited, and the angle of relative rotation between the first body 10 and the second body 20 may be greater than 180 °, or may be only in a range of less than 180 °.

The second connecting portion 21 of the second body 20 is rotatably connected to the first connecting portion 11 of the first body 10 around a first axis a, and rotatably connected to the mounting seat 22 around a second axis b, so that an angle between the mounting seat 22 and the first body 10 is adjustable, and the second axis b is parallel to the first axis a.

It should be noted that the mutual perpendicularity in the present application is not absolute perpendicularity, and is approximately perpendicularity due to machining errors and assembly errors (for example, the angle between the two structural features is 89.9 deg.) and is within the mutually perpendicular range of the present application. In addition, the latter-mentioned mutual parallelism is not absolute, and approximate parallelism (for example, an angle between two structural features of 0.1 °) due to machining errors and assembly errors is also within the scope of mutual parallelism in the present application. This application is not particularly limited, and the description of mutually perpendicular and mutually parallel definitions is not repeated hereinafter.

In one embodiment, the second connecting portion 21 is rotatably connected to the mounting base 22 through the second rotating shaft 23, and at this time, the axis of the second rotating shaft 23 is the second axis b. Further, the second connecting portion 21 and the mounting seat 22 are connected by damping rotation, so that the second connecting portion 21 and the mounting seat 22 can relatively rotate to any angle and keep fixed, and the angle adjustment between the mounting seat 22 and the second connecting portion 21 is achieved. At this time, by adjusting the rotation angle between the mounting seat 22 and the second connection portion 21 and the angle between the second connection portion 21 and the first body 10, the relative angle between the mounting seat 22 and the first body 10 can be flexibly adjusted, so that the angle between the host 2 fixedly mounted on the mounting seat 22 and the first body 10 can be adjusted to improve the flexibility of the second body 20 supporting the host 2.

In one embodiment, the host 2 is detachably and fixedly disposed on the mounting base 22 through a magnetic manner. The host machine 2 can be installed and fixed on the installation seat 22 of the foldable support 1 for operation and use, and can also be separated from the foldable support 1 for independent use, so that the flexibility of the use of the host machine 2 is improved. In other alternative embodiments, the host 2 may be fixedly disposed on the mounting base 22 by a detachable connection such as a snap connection, a bolt-and-nut connection, or the like. Further, the mounting seat 22 can also be arranged to be detachably connected with the host computer 2, so that when the host computer 2 is fixedly mounted on the mounting seat 22, the mounting seat 22 can also play a role in protecting the host computer 2, the host computer 2 is prevented from being damaged due to external impact force in the use process, and the reliability and durability of the host computer 2 in use are improved.

It will be appreciated by those skilled in the art that in other alternative embodiments, the host 2 may be directly fixedly disposed on the mounting base 22, for example, fixedly mounted on the mounting base 22 by bonding, welding, or the like. Further, the host 2 and the mounting seat 22 may be integrally formed, and the mounting seat 22 may be directly used as a part of the housing of the host 2. Specifically, the connection manner between the host 2 and the mounting base 22 is not limited in this application.

In one embodiment, the mounting seat 22 and the second connecting portion 21 of the second main body 20 are both in a plate-shaped structure, on one hand, when the foldable stand 1 is in a folded state, the second main body 20 can be stacked with other components to reduce the thickness of the foldable stand 1, thereby reducing the space occupation of the foldable stand 1 and improving the portability of the foldable stand 1; on the other hand, when the foldable stand 1 is in the open state, the mount 22 and the second connection part 21, and the second connection part 21 and the first body 10 can be flexibly rotated relative to each other, and have sufficient supporting strength to provide stable supporting force, thereby ensuring that the second body 20 can stably and flexibly support the main body 2.

In other alternative embodiments, the second connecting portion 21 and the mounting base 22 may be configured in other rigid structures, for example, the second connecting portion 21 may be configured in an i-shaped rod structure, and the mounting base 22 may be configured as a suction cup, which only needs to enable the second connecting portion 21 to be rotatably connected with the mounting base 22 and have sufficient supporting strength.

Further, in other alternative embodiments, the second connecting portion 21 and the mounting seat 22 may not be limited to rotate around the second axis b, for example, an end of the second connecting portion 21 connected to the mounting seat 22 is configured to be spherical, and the mounting seat 22 is rotationally matched with the spherical end of the second connecting portion 21, at this time, the mounting seat 22 may rotate freely in space relative to the second connecting portion 21, so that flexibility of supporting the host 2 by the second main body 20 through the mounting seat 22 is further improved, and flexibility of using the foldable stand 1 is improved.

It will be appreciated by those skilled in the art that the second body 20 need only be rotatably coupled to the first body 10 and support the main body 2. Thus, in other alternative embodiments, the second body 20 may be provided as only one support plate, or to ensure flexibility in supporting the second body 20, the second body 20 may be provided as an arbitrarily plastic cantilever (e.g., a cantilever made of carbon steel may be freely bent a plurality of times and may provide sufficient supporting force).

In other alternative embodiments, the second body 20 may also be used to support other objects to be supported, such as a picture frame, a molder, etc. In addition, the second body 20 may also support a plurality of objects to be supported at the same time, and in particular, the present application is not limited thereto.

It should be noted that, the host 2 may include a tablet computer, a smart phone, a display device, a smart wearable device, or the like, which is not limited in this embodiment of the present application. In this application, the host 2 is illustrated as a tablet pc.

The host 2 includes a display area 201, the display area 201 is used for displaying a picture, and has a visual angle a, and when a user's viewing angle is within the visual angle a of the display area 201 of the host 2, the content displayed in the display area 201 can be clearly seen (as shown in fig. 5). Further, the visual experience of the user is best when the user's viewing angle is facing the display area 201 of the host 2.

Therefore, when the foldable stand 1 is in the opened state to support the host 2, in order to ensure that the user has an optimal visual experience, the second body 20 of the foldable stand 1 can support the host 2, and by adjusting the angle of the host 2 relative to the first body 10, the display area 201 of the host 2 is opposite to the user, so as to ensure that the user can clearly see the content displayed in the display area 201 of the host 2.

Further, since the angle between the main body 2 and the first main body 10 supported by the foldable stand 1 is adjustable, the main body 2 can be supported by the foldable stand 1 when different users or users use the electronic device 100 in different postures, so that the display area 201 of the main body 2 can be opposite to the viewing angle of the users, and the users can have optimal visual experience.

It will be appreciated by those skilled in the art that the viewing angle a of the display area 201 of the host 2 has a certain range, so that when the display area 201 of the host 2 is not facing the user's viewing angle, it is only necessary to ensure that the user's viewing angle is within the range of the viewing angle a of the display area 201 of the host 2, and it is ensured that the user can see the content displayed by the display area 201 of the host 2. Thus, in other alternative embodiments, the foldable stand 1 need only support the host 2 such that the user's viewing angle remains within the viewing angle a of the display area 201 of the host 2.

Referring to fig. 6 to 8, fig. 6 is a side view illustrating a structure of an electronic device in an opened state according to an embodiment of the present application, fig. 7 is a schematic exploded structure of the electronic device according to an embodiment of the present application, and fig. 8 is a schematic structure of a first body and a connecting shaft according to an embodiment of the present application.

As shown in fig. 6 to 8, and as will be understood with reference to fig. 2 and 3, the first body 10 includes a first connection part 11 and a base 12, wherein one side of the first connection part 11 is rotatably connected to the second body 20 about a first axis a, the base 12 has an operation region 121, and the base 12 is slidably connected to the first connection part 11 such that a distance d between the operation region 121 of the base 12 and the first axis a is adjustable. Meanwhile, the input device 3 (e.g., including the keyboard 301 and the touch pad 302) is disposed on the base 12 of the first body 10, and an operable area of the input device 3 is located within the operation area 121 of the base 12.

In one embodiment, the input device 3 is fixedly disposed on the base 12 of the first body 10, and a portion of the input device 3 is embedded in the base 12, so as to ensure that the input device 3 is stably fixed on the base 12.

In other alternative embodiments, the input device 3 may also be detachably and fixedly connected to the base 12 of the first body 10, for example, magnetically, by a snap connection, by a bolt-and-nut connection, etc., so that the input device 3 may be freely detached from or mounted on the base 12 to improve the flexibility of use of the input device 3. Further, the input device 3 may be directly and stably placed on the upper surface of the base 12 of the first body 10, and only the operable area of the input device 3 needs to be located in the operation area 121 of the base 12.

In one embodiment, the input device 3 may be configured as a keyboard 301 and a touch pad 302, and the touch pad 302 is disposed on a side of the keyboard 301 away from the first axis a. The input device 3 may be connected to the host 2, and may input to the host 2 to operate or control the host 2, for example, text input to the host 2 through the keyboard 301, or control applications and software in the host 2 through the touch pad 302. In other alternative embodiments, the input device 3 may also be configured as another input device that is connectable to the host 2, for example, a remote sensing device, or another host may be used as the input device 3.

Those skilled in the art will appreciate that in other alternative embodiments, the input device 3 may be configured as a keyboard 301 only or a touch pad 302 only, or the input device 3 may further include other input devices, such as a remote sensing device, etc.

In one embodiment, the operable area of the input device 3 is arranged corresponding to the operation area 121 of the base 12, or it may be understood that the operable area of the input device 3 is arranged coincident with the operation area 121 of the base 12. In other alternative embodiments, the operable area of the input device 3 may be smaller than the operable area 121 of the base 12, and the operable area of the input device 3 may be located in the operable area 121 of the base 12.

The key area of the keyboard 301 and the touch area of the touch pad 302 in the input device 3 are both operable areas of the input device 3. And in order to ensure that the user can normally operate the operable area of the input device 3, a certain operation space p needs to be provided to the user above the operable area of the input device 3 so as to facilitate the user's free operation and use of the input device 3. The operable area of the input device 3 may be understood as an area of the input device 3 where an operation may be performed, for example, a key of the keyboard 301, an entire touch area of the touch pad 302, a joystick of a remote sensing apparatus, and the like. The user, while using the input device 3, needs to interact with the operable area of the input device 3 to complete the input. At this time, the input device 3 and the host 2 are matched to simulate the operation mode of the notebook computer, so as to satisfy the operation habit of the user and improve the efficiency of controlling the electronic device 100.

Therefore, when the user manipulates the host 2 through the input device 3 in the open state, the user needs to ensure that the display area 201 of the host 2 faces the user, so that the user can see the display area 201 of the host 2 when using the input device 3, and has an optimal viewing angle experience. Meanwhile, the operation space p of the host 2 and the operation space p of the input device 3 are mutually staggered, so that the influence on the normal use of the input device 3 by a user is avoided.

In one use scenario, when the foldable stand 1 is switched from the folded state to the unfolded state, the second body 20 rotates relative to the first body 10 in a direction away from the first body 10, and supports the host 2 such that the display area 201 of the host 2 is opposite to the viewing angle of the user, so as to ensure that the user can see the display area 201 of the host 2 clearly, thereby ensuring that the user has a good visual experience. At this time, the angle B formed between the input device 3 of the first body 10 and the display area 201 of the host 2 is within the range of the operation angle. Or it may be understood that when the angle B formed by the input device 3 and the display area 201 of the host 2 is within the range of the operation angle, the user can see the display area 201 of the host 2 when operating the input device 3.

At the same time, in order to shift the operation space p of the host 2 and the input device 3 from each other, the mount 12 provided with the operation area 121 is moved in a direction away from the first axis a with respect to the first connection portion 11 (i.e., the telescoping direction X of the mount 12 with respect to the first connection portion 11), so that the interval between the operation area 121 of the mount 12 and the first axis a increases. At this time, the operation space p above the operation area 121 of the base 12 is offset from the main unit 2 in the expansion and contraction direction X. Or it can be understood that the orthographic projection of the host 2 on the plane c of the surface of the operation area 121 is staggered with the operation area 121, so that the interference between the host 2 and the operation space p above the operation area 121 is avoided. It is ensured that the user can freely manipulate the host 2 via the input device 3.

Further, since the base 12 moves relative to the first connecting portion 11 in a direction away from the first axis a (i.e. the telescopic direction X of the base 12 relative to the first connecting portion 11), the length of the first main body 10 along the telescopic direction X is increased, so that the supporting surface of the first main body 10 placed on the surface of another object is increased, and further stability and reliability of the first main body 10 for supporting the whole electronic device 100 are improved.

Further, since the main body 2 is displaced from each other in the expansion and contraction direction X with respect to the operation space p, the main body 2 can be freely moved in a direction perpendicular to the expansion and contraction direction X (for example, the height direction Z shown in fig. 6), without interfering with the operation space p. Thus, in other alternative embodiments, the second body 20 may support the main body 2 when the foldable stand 1 is in the open state, with the lower edge of the main body 2 abutting against the upper surface of the first body 10. On the one hand, the upper surface of the first body 10 may support the main machine 2 to improve the stability of the foldable stand 1 supporting the main machine 2; on the other hand, the height of the second body 20 supporting the main body 2 is reduced, thereby reducing the height of the center of gravity of the main body 2, and further improving the stability and reliability of the second body 20 supporting the main body 2.

In one embodiment, the operating angle B between the input device 3 and the display area 201 of the host 2 may be 90 ° to 130 °. In other alternative embodiments, the operating angle B may also be less than 90 °, or greater than 130 °, since the display area 201 of the host 2 has a different viewing angle a.

In another use scenario, when the foldable stand 1 is switched from the open state to the folded state, the second body 20 rotates relative to the first body 10 towards the direction of the first body 10, so that the host 2 supported by the second body 20 and the input device 3 disposed on the first body 10 are stacked on each other, thereby maximally reducing the volume of the electronic device 100, and facilitating carrying and storing of the electronic device 100. Meanwhile, the first main body and the second main body 20 of the foldable bracket 1 clamp the host computer 2 and the input device 3 relatively, so that the host computer 2 and the input device 3 are wrapped in the foldable bracket 1, the foldable bracket 1 can play a role in protecting the host computer 2 and the input device 3, the reliability of the electronic equipment 100 is improved, and the host computer 2 and the input device 3 in the foldable bracket 1 are prevented from being damaged due to external force in the process of carrying and accommodating the electronic equipment 100. At the same time, the base 12 moves in the direction of the first axis a relative to the first connection 11, so that the distance between the operation region 121 of the base 12 and the first axis a decreases. At this time, the entire length of the first body 10 is reduced, so that the entire length of the foldable stand 1 is reduced, and the size of the foldable stand 1 in the folded state is further reduced, thereby reducing the overall volume and space occupation of the electronic device 100, and improving portability of the electronic device 100.

It will be appreciated by those skilled in the art that the host 2 and the input device 3 may be detachably connected to the foldable stand 1, so that in other usage scenarios, the foldable stand 1 may be carried and stored separately, and the object to be supported and/or the input device 3 may be placed on the foldable stand 1 according to the actual requirement of the user.

In other alternative embodiments, the foldable stand 1 may be combined with the input device 3 and used as an input apparatus. The input device 3 is disposed on the base 12 of the first body 10, and the operable area of the input device 3 is located in the operation area 121 of the base 12. Further, the input device 3 is arranged to: and is operable to control an object to be supported mounted on the second body 20.

In other alternative embodiments, the input device 3 may not be provided on the first body 10, so that the foldable stand 1 may be used as another electronic device in combination with the host 2. In use, the host computer 2 may be supported by the foldable stand 1 only, or the input device 3 may be placed in the operation area 121 of the first body 10, so that the host computer 2 of the electronic apparatus 100 may be controlled by the input device 3.

As shown in fig. 9 to 15b, and as will be understood with reference to fig. 2 and 3, the first connecting portion 11 of the first body 10 is slidably engaged with the base 12 by a telescopic structure, and the first connecting portion 11 is retractable into the base 12. Thus, in the contracted state of the first body 10, the length of the first body 10 in the telescopic direction X is minimized to minimize the size of the first body 10, to enhance portability of the foldable stand 1, and to enhance aesthetic appearance of the foldable stand 1 in the folded state. Meanwhile, the first connecting portion 11 may extend out of the base 12 by a certain distance, so that the first main body 10 is in an extended state, and at this time, the length of the first main body 10 along the extending and contracting direction X is the largest, and the area of the formed supporting surface is the largest, so as to have the best supporting stability.

In one embodiment, as shown in fig. 9, the first connecting portion 11 is configured as a sliding cover structure, and the base 12 is configured as a plate structure, so that the first body 10 can be better placed on the surface of a table top, or other objects.

As shown in fig. 9 to 13c, in one embodiment, the first connection portion 11 includes a sliding upper cover 111 and a sliding lower cover 112 that are fixedly spliced up and down, wherein a side of the sliding upper cover 111 and the sliding lower cover 112 facing away from the base 12 are spliced relatively to form a sleeve structure, and the sliding upper cover 111 and the sliding lower cover 112 are rotatably connected with the connection shaft 30 through the sleeve structure, so that the connection shaft 30 can freely rotate with respect to the sliding upper cover 111 and the sliding lower cover 112. Further, the sliding upper cover 111 and the sliding lower cover 112 are spliced up and down to form a sliding cover structure, so that the portion of the first connecting portion 11 extending out of the base 12 is wrapped by the sliding cover structure, and dust, water vapor and the like are prevented from entering the sliding cover structure, so that internal components of the sliding cover structure are corroded or worn.

Meanwhile, at least one guide assembly 13 is arranged between the sliding upper cover 111 and the sliding lower cover 112, and the sliding upper cover 111 and the sliding lower cover 112 are in sliding connection with the base 12 through the at least one guide assembly 13, so that sliding fit between the first connecting portion 11 and the base 12 is more stable, and the base 12 slides more smoothly relative to the first connecting portion 11.

In one embodiment, two guiding assemblies 13 are provided between the first connecting portion 11 and the base 12, so as to ensure that a stable sliding connection can be maintained between the first connecting portion 11 and the base 12. The guide assembly 13 includes a guide rail 131 fixedly disposed on the sliding upper cover 111 and a sliding block 132 slidably disposed on the guide rail 131 (as shown in fig. 14a and 14 b). The sliding block 132 is fixedly disposed on the base 12, and the base 12 and the first connecting portion 11 form a stable sliding fit by the sliding fit of the sliding block 132 and the guide rail 131.

In other alternative embodiments, the first connecting portion 11 may also be directly slidingly engaged with the base 12, so as to simplify the structure of the foldable stand 1, reduce the overall weight of the foldable stand 1, and improve portability of the foldable stand 1, for example, directly disposing a sliding rail on the base 12, and the first connecting portion 11 is provided with a sliding protrusion corresponding to the sliding rail of the base 12, and by sliding the sliding protrusion and the sliding rail, the first connecting portion 11 is slidingly engaged with the base 12. Further, 3 or more than 3 guiding assemblies 13 may be disposed between the first connecting portion 11 and the base 12, so as to enhance stability and reliability of sliding fit between the first connecting portion 11 and the base 12.

In one usage scenario, the user may simultaneously stretch the first connection portion 11 and the base 12 along the expansion and contraction direction X of the first body 10 such that the first connection portion 11 slides and extends relative to the base 12, or the user may relatively squeeze and stretch the first connection portion 11 and the base 12 along the expansion and contraction direction X of the first body 10 such that the first connection portion 11 slides and contracts relative to the base 12.

In one embodiment, a linkage structure 14 is further disposed between the sliding upper cover 111 and the sliding lower cover 112, and one end of the linkage structure 14 is connected to the connecting shaft 30, and the other end is connected to the base 12; when the connecting shaft 30 rotates, the connecting shaft 30 can push the base 12 to slide relative to the first connecting portion 11 through the linkage structure 14. Therefore, a user can slide the base 12 relative to the first connecting portion 11 only by rotating the connecting shaft 30, so as to improve the flexibility and operability of the extension and retraction of the first body 10.

In other alternative embodiments, the linkage 14 may be disposed at other locations, for example, between the first connection portion 11 and the base 12, and the user may slide the base 12 relative to the first connection portion 11 by manipulating the linkage 14. For example, the linkage structure 14 is configured as a driving motor and a control button, and the user operates the control button of the linkage structure 14, so that the driving motor of the linkage structure 14 drives the base 12 to slide relative to the first connection portion 11.

In one embodiment, the base 12 is fixedly provided with a reinforcing plate 122 slidably connected to the first connecting portion 11, and the reinforcing plate 122 is used for increasing the structural strength of the base 12 and improving the stability and reliability of the connection between the first connecting portion 11 and the base 12. Wherein the stiffening plate 122 is provided with a first mounting point 123 for mounting the fixed slider 132 and a second mounting point 124 for mounting one end of the fixed linkage 14 (as shown in fig. 15a and 15 b).

In one embodiment, the stiffener 122 is fixedly disposed within the base 12 by a bolt and nut. In other alternative embodiments, the stiffening plate 122 may be coupled to the base 12 in other ways, such as integrally formed.

In order to further illustrate the relative fixing relationship between the first main body and the structures in the first main body, please refer to fig. 16, fig. 16 is a partial structural cross-sectional view of the electronic device without the host according to the embodiment of the present application, and fig. 16 shows a simplified schematic diagram of the internal relationship between the first main body and the structures in the first main body, it should be noted that fig. 16 is not meant to represent the actual structure of the foldable stand according to the embodiment of the present application, but rather, the funnel shape shown in fig. 16 represents the relative fixing between two components connected by the funnel shape.

As shown in fig. 16, the sliding upper cover 111, the sliding lower cover 112, the base 148, and the guide rail 131 are relatively fixed; the moving block 142 and the sliding block 132 are fixedly arranged on the reinforcing plate 122 of the base 12. Further, the sliding block 132 is slidably connected to the guide rail 131, and the moving block 142 is slidably connected to the base 148, so that the first connecting portion 11 is slidably connected to the base 12.

Referring to fig. 17a to 21c, fig. 17a and 17b are schematic structural views of the linkage structure and the connecting shaft in the extended state and the contracted state according to the embodiment of the present application, fig. 18 is a schematic structural view of the linkage structure in the extended state according to the embodiment of the present application, fig. 19a to 19c are a schematic structural view, a schematic structural bottom view and a schematic structural side view of the linkage structure in the extended state according to the embodiment of the present application, and fig. 20 is a schematic structural view of the linkage structure in the contracted state according to the embodiment of the present application, and fig. 21a to 21c are a schematic structural view, a schematic structural bottom view and a schematic structural side view of the linkage structure in the contracted state according to the embodiment of the present application.

As shown in fig. 17a to 21c, and as will be understood with reference to fig. 4a, 4b, and 10 to 13c, the first connecting portion 11 is rotatably connected to the second body 20 through a connecting shaft 30, wherein the second connecting portion 21 is connected to the connecting shaft 30 and rotates synchronously with the connecting shaft 30, so that when the second body 20 rotates relative to the first connecting portion 11, the second body 20 can drive the connecting shaft 30 to rotate synchronously and rotate the connecting shaft 30 relative to the first body 10.

In one example, the second connecting portion 21 is provided with shaft sleeves 210 corresponding to two ends of the connecting shaft 30, and the shaft sleeves 210 of the second connecting portion 21 are fixedly connected with two ends of the connecting shaft 30, so that the second connecting portion 21 can drive the connecting shaft 30 to rotate synchronously. In other alternative embodiments, the second connection portion 21 may be connected to the connection shaft 30 in other manners, for example, the second connection portion 21 may be connected to the connection shaft 30 in an integrally formed manner.

In one use scenario, when the foldable stand 1 is switched from the folded state to the unfolded state, the second body 20 rotates relative to the first body 10 in a direction away from the first body 10, thereby driving the connecting shaft 30 to rotate relative to the first connecting portion 11 in the first direction, at this time, in response to the rotation of the connecting shaft 30, the linkage structure 14 pushes the base 12 to slide relative to the first connecting portion 11 in a direction away from the first axis a, so that the operation area 121 of the base 12 moves away from the first axis a. Therefore, in the process of switching the foldable stand 1 from the folded state to the unfolded state, the base 12 can move towards the direction deviating from the first axis a (i.e. the telescopic direction X of the first main body 10) at the same time, so that the first main body 10 is elongated, the operation area 121 of the base 12 and the host 2 are ensured to be staggered relatively in the telescopic direction X, and the user can operate the input device 3 on the base 12 to operate the host 2 normally. The use flow of the foldable support 1 is simplified, and the convenience of using the foldable support 1 is improved.

In another use scenario, when the foldable stand 1 is switched from the open state to the folded state, the second body 20 rotates relative to the first body 10 in the direction of the first body 10, thereby driving the connecting shaft 30 to rotate relative to the first connecting portion 11 in the second direction, at this time, in response to the rotation of the connecting shaft 30, the linkage 14 pushes the base 12 to slide relative to the first connecting portion 11 in a direction approaching the first axis a, so that the operation area 121 of the base 12 moves toward the first axis a. So that the base 12 can be simultaneously moved in a direction approaching the first axis a (i.e., the telescoping direction X of the first body 10) during the switching of the foldable stand 1 from the unfolded state to the folded state, so that the first body 10 is contracted, and the foldable stand 1 is kept in the folded state in a state of minimum size, thereby ensuring portability of the foldable stand 1 in the folded state. And the use flow of the foldable support 1 is simplified, and the convenience of using the foldable support 1 is improved.
