Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the description of the present disclosure, it should be understood that the terms "center", "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientation or positional relationship of a user when using the terminal, and are not intended to limit the present disclosure.

As shown in fig. 1 to 9, an embodiment of the present disclosure provides a side key structure, including:

the keys are pressed on the keyboard,

a first elastic member 120 contacting the key in a longitudinal direction;

a side key, comprising: a limit structure 150 and a side key body 140 connected with the limit structure 150 and used for acting sliding force;

when the side key body is driven by external force, the limiting structure 150 is driven to move between a first position and a second position;

the limiting structure is located at the first position, the limiting structure 150 is matched with the matching structure of the key, and the key is locked to move in the longitudinal direction;

In some specific examples, the lock of the limiting structure on the key can be locked and unlocked through a buckle structure, such as: the limiting structure is provided with a limiting fixture block, the matching structure on the key can be a limiting clamping groove formed by bending the elastic arm, when external force is applied to the side key body, the side key body drives the limiting structure to move, the limiting fixture block is embedded into the limiting clamping groove, the limiting structure and the key are locked, and the key cannot move longitudinally. When an opposite external force is applied to the side key body, the limiting clamping block is separated from the limiting clamping groove, the limiting structure and the key are unlocked, and the key can restore to longitudinally move. The external force applied to the side key body may be an external force in the longitudinal direction or a force in the transverse direction.

In some specific examples, the locking of the key by the limiting structure can be locked and unlocked through a magnetic structure. For example: the limiting structure is provided with a first magnet, the matching structure of the key comprises a second magnet, when external force is applied to the side key body, the side key body drives the limiting structure to move, different magnetic poles of the first magnet and the second magnet are in mutual contact to generate attractive force, the limiting structure and the key are locked, and the key cannot move longitudinally. When the side key body is exerted with an opposite direction external force, the same magnetic poles of the first magnet and the second magnet are contacted with each other to generate a repulsive force, the limit structure and the key are unlocked, and the key can restore to move longitudinally. The external force applied to the side key body may be an external force in the longitudinal direction or a force in the transverse direction.

It will be appreciated that the manner of locking and unlocking between the limit structure and the key is not limited to that described above.

In addition, the moving direction of the side key body and the moving direction of the limiting structure can be the same or different. For example: when the external force of lateral direction is applyed to the side key body, limit structure can move along the lateral direction.

For another example, when an external force in the longitudinal direction is applied to the side key body, the limiting structure can also move in the transverse direction. At this moment, the side key structure still includes gear drive structure, or screw drive structure, and gear drive structure or screw drive structure connect side key body and limit structure respectively. Utilize gear drive structure or lead screw drive structure, will apply to the longitudinal direction power of side key body and change into horizontal direction power to drive limit structure horizontal direction and remove.

The key in the embodiments of the present disclosure may be a mechanical key having a solid body, but is not limited to a machine. The key can conduct the circuit or interrupt the circuit to make the circuit non-conductive, which can be called as a key switch, and has a switching function. Compared with a pressure key without a solid key, the solid key of the embodiment of the disclosure improves the experience of the user during operation. Moreover, when the position-limiting structure is located at the first position, the key cannot move in the longitudinal direction, and the switch function of the key and the lifting function of the first elastic member 120 on the key cannot be realized. When the limiting structure is located at the second position, the key can move along the longitudinal direction, and the switch function of the key and the lifting function of the key by the first elastic element 120 are not affected. Therefore, by applying external force to the side key body 140, the use state of the keys can be adjusted, various requirements of a user are met, and the use experience is improved.

The first elastic member 120 is located at the bottom of the key, so that when the key is pressed, the first elastic member 120 is compressed.

When the limiting structure is located at the second position, the side key is located outside the compression and stretching space of the first elastic member 120, and the movement of the first elastic member 120 is not limited, so that the first elastic member 120 can freely stretch and retract. When the terminal with the side key structure of the present disclosure encounters an unexpected situation such as falling or collision, the external force can be buffered by utilizing the expansion of the first elastic member 120, so as to protect the keys. Moreover, the side key structure provided by the embodiment of the disclosure has lower cost compared with an electric automatic lifting side key structure, and the side key structure adopting the manual control key to lift is low in cost.

In embodiments of the present disclosure, the side key may be a mechanical key having a solid body. In practical applications, the fixing of the limiting structure at the first position or the second position can be achieved by a tight fit with the middle frame of the terminal, for example, as shown in fig. 1, the middle frame 110 has a sliding hole 214, the side key body 140 has a convex pillar 141 formed to protrude toward the limiting structure 150, the convex pillar 141 is fixed with the limiting structure 150, and the convex pillar 141 passes through the sliding hole 214. The convex column 141 is tightly matched with the sliding hole 214, when the side key body 140 is acted by acting force, the convex column 141 can slide in the sliding hole 214 along the transverse direction, when the acting force is not acted, the convex column 141 can not slide in the sliding hole 214, and the side key can be fixed on the middle frame 110.

The first elastic member 120 is, without limitation, a spring or a leaf spring. For example, the first elastic element 120 is a compression spring, or the first elastic element 120 is a spring sheet formed by bending a metal sheet or an alloy sheet.

In other alternative embodiments, the stop structure is movable in the transverse direction from a first position to a second position.

In a specific example, the side key structure includes:

pressing a key;

the first elastic pieces are distributed in parallel with the keys along a first direction and are in contact with the keys;

a side key, comprising: the side key body is fixed on the limiting structure and is used for acting a sliding force; the limiting structure is positioned between the key and the first elastic piece;

when the side key body is subjected to external force in the transverse direction, the side key body can drive the limiting structure to move from the first position to the second position in the transverse direction; the transverse direction is vertical to the longitudinal direction;

the limiting structure is located at the first position and is clamped and locked with the first end of the key;

the limiting structure is located at the second position, the second end of the key is disengaged from the limiting structure 150, and the key can move in the longitudinal direction based on the elasticity of the first elastic element 120; the second end of the key is the opposite end of the first end of the key.

The side keys are movable in the lateral direction but not in the longitudinal direction. When the side key body is driven by external force in the transverse direction, the limiting structure also moves in the transverse direction. The key is mounted on the middle frame 210 of the terminal, and as shown in fig. 1 and 6, the longitudinal direction is the same as the deformation direction of the first elastic member 120, for example, the longitudinal direction is the up-down direction parallel to the long side of the middle frame 210 of the terminal, and the transverse direction is the left-right direction parallel to the short side of the middle frame 210 of the terminal. When the side key body 140 is pushed laterally, the side key body 140 can drive the limiting structure 150 to move along the lateral direction relative to the key. In contrast, in the longitudinal direction, the height of the key when the limiting structure is in the first position is lower than the height of the key when the side key is in the second position. Therefore, when the position limiting structure is located at the first position, the key can be hidden inside the middle frame 210, and at this time, the first elastic element 120 stores elastic force, and the switch function of the key cannot be used. When a certain function of the terminal needs to be opened, for example, when the game function of the terminal is opened, the limiting structure is moved from the first position to the second position by applying an external force to the side key body 140 along the transverse direction, the limiting structure 150 releases the locking of the keys, at this time, the first elastic member 120 releases the elastic force, the keys are at least partially popped out of the middle frame 210, the keys exposed out of the middle frame 210 can be touched by a user, and the switch function of the keys can be further realized. The mode of popping up the keys provides the user with the ceremony feeling of starting a certain function, and improves the use experience. After the function is used, the user can apply sliding force in the opposite direction to the lateral key body 140 again along the transverse direction, and then the limiting structure 150 is restored to the first position from the second position again to hide the key, and the operation is repeated.

In other alternative embodiments, the keys include:

a key body 110;

the detection circuit 130 is distributed in parallel with the key body 110 along the longitudinal direction;

the second elastic element 180 is positioned between the key body 110 and the detection circuit 130, when the key body 110 is pressed, the second elastic element 180 is compressed, contacts with the detection circuit 130 and conducts the detection circuit 130; when the key body 110 is not pressed, the second elastic member 180 is reset, and the second elastic member 180 is separated from the detection circuit 130 and disconnects the detection circuit 130.

As shown in fig. 1, 4 and 7, the key body 110 is block-shaped, and when the key body 110 is acted by an acting force, the second elastic member 180 can be compressed, so that the second elastic member 180 contacts with the detection circuit 130 and conducts the detection circuit 130, or when the external force is removed, the second elastic member 180 resets, the second elastic member 180 and the connection terminal are distributed at intervals, and at this time, the key cannot conduct the circuit on the detection circuit 130 through the second elastic member 180.

Without limitation, in some examples, the key body trigger detection circuit being conductive does not necessarily indicate that the key is in an enabled state, i.e.: whether the key is enabled or not also requires the processor in the terminal to further send instructions. For example: when the key is in the hidden state, although the second elastic element is continuously contacted with the detection circuit to turn on the detection circuit, the key can be in the closed state without executing any operation.

The detection circuit 130 may be formed of a conductive material such as metal or alloy on a base material, the detection circuit may be electrically connected to a game chip or a main board in the terminal, and the base material may be made of insulating engineering plastic such as polyamide or polyphenylene sulfide. The second elastic member 180 may be fixed to the key body 110 or may be fixed to a substrate.

The second elastic member 180 includes, without limitation, a spring sheet or a spring, etc.

In other alternative embodiments, the elastic coefficient of the second elastic member 180 is smaller than that of the first elastic member 120.

In contrast, when the key is pressed by using a smaller first acting force, the first acting force is transmitted to the second elastic member 180 and the first elastic member 120 through the key, respectively, since the elastic coefficient of the second elastic member 120 is smaller, the second elastic member is more easily deformed, and the elastic coefficient of the first elastic member 120 is larger, the first elastic member is less easily deformed or the deformation amount is very small, compared with the deformation amount of the second elastic member 180, the deformation amount of the first elastic member 180 is negligible, and further when the limiting structure 150 is located at the second position, the key is pressed to realize the switching function of the on or off of the detection circuit 130, and the lifting function of the key is not triggered. When the key is pressed with a second large force, the second elastic member 180 and the first elastic member 120 are deformed at the same time.

In other alternative embodiments, the first end of the key body 110 has a protrusion, the second end of the key body 110 has a matching structure formed as a first limiting groove 113, and the first end of the key body 110 is the opposite end of the second end of the key body 110;

the limiting structure 150 has a first through hole 151, and the protrusion of the key body 110 is embedded into the first through hole 151;

when the limiting structure is located at the first position, the limiting structure 150 is inserted into the first limiting groove 113, and the movement of the key in the longitudinal direction is locked;

As shown in fig. 8 and 9, when the position limiting structure is at the first position, the position limiting structure 150 is engaged with the first position limiting groove 113, the protrusion passing through the first through hole 151 abuts against the sidewall of the first through hole 151, and the key body 110 is limited and cannot move in the longitudinal direction. When the side key is at the second position, the position of the first through hole 151 moves while the position-limiting structure 150 is separated from the first position-limiting groove 113, and the protrusion is not interfered by the inner wall of the first through hole 151, for example, a gap is formed between the inner wall of the first through hole 151 and the protrusion. The first through hole 151 serves as an avoiding hole and can avoid a protrusion, so that when the limiting structure is located at the second position, the movement of the key body 110 along the longitudinal direction is not affected. When the first elastic member 120 is compressed, the first limiting groove 113 approaches the first elastic member 120 along with the key body 110, at this time, the first limiting groove 113 can be aligned with the limiting structure 150, the side key body 140 is pushed to drive the limiting structure 150 to enter the first limiting groove 113, so as to lock the key body 110, and the entire key is also in a locked state.

Further, the side key body has a convex column 141 formed by protruding towards the limiting structure 150, and the convex column 141 is fixed with the limiting structure 150.

The side key body 140 is connected to the limiting structure 150 through the protruding pillar 141. As shown in fig. 1, 8 and 9, the limiting structure 150 has mounting holes that are distributed in parallel with the first through hole 151 in the transverse direction, the mounting holes are aligned with the protruding columns 141, the protruding columns 141 are embedded in the mounting holes, in order to further strengthen the connection between the protruding columns 141 and the limiting structure 150, the side key further includes pins 142, the limiting structure 150 further has first locking holes that are perpendicular to and communicated with the mounting holes, the protruding columns 141 have second locking holes that are aligned with the first locking holes, and the pins 142 are located in the first locking holes and the second locking holes to further fix the side key body 140 and the limiting structure 150.

In other alternative embodiments, the key further comprises:

the sliding seat 160, the key body 110 and the detection circuit 130 are all installed on the sliding seat 160; the first elastic member 120 is in contact with the sliding seat 160.

As shown in fig. 2 to 4, slide holder 160 is used to mount and fix detection circuit 130, and, without limitation, slide holder 160 has a mounting hole, and detection circuit 130 also has a mounting hole, and detection circuit 130 is fixed to slide holder 160 by passing a fastener such as bolt 190 through the mounting hole of detection circuit 130 and the mounting hole of slide holder 160 in this order.

The key body 110 can move relative to the sliding seat 160 and the detection circuit 130. The elastic force of the first elastic element 120 can push the sliding seat 160 to move along the longitudinal direction, and the sliding seat 160 further drive the detection circuit 130, the second elastic element 180 and the key body 110 to move.

Of course, the sliding seat 160 may not be provided, the first elastic element 120 directly contacts the detection circuit 130, the first elastic element 120 pushes the detection circuit 130 to move along the longitudinal direction, and the detection circuit 130 drives the second elastic element 180 and the key body 110 to move.

In other alternative embodiments, the key body 110 has a first limiting hole 111;

a sliding seat 160 having a second limiting hole opposite to the first limiting hole 111;

the button still includes:

the fixing pin 170 sequentially passes through the first limiting hole 111 and the second limiting hole to limit the key body 110 from being separated.

Further, the length of the first limiting hole 111 along the longitudinal direction is greater than or equal to the deformation length of the first elastic member 120 along the longitudinal direction.

As shown in fig. 1 to 4, the fixing pin 170 is located in the first position-limiting hole 111 and the second position-limiting hole to limit the key body 110 from being separated from the sliding seat 160, and meanwhile, the fixing pin 170 can move in the first position-limiting hole 111 to ensure that the elastic force of the second elastic element 180 can push the key body 110 to move relative to the sliding seat 160, and the elastic force of the first elastic element 120 can push the sliding seat 160 and the key body 110 to move along the longitudinal direction.

Without limitation, the first limiting hole 111 is a kidney-shaped hole.

The keys are, without limitation, game control keys. Alternatively, the keys may be used as power keys or volume adjustment keys as desired.

An embodiment of the present disclosure further provides a terminal, including:

the side key structure of any of the embodiments described above;

the middle frame 210 is provided with a bottom plate 211, a side wall 212 positioned at the edge of the bottom plate 211, and a chamber 213 formed by the bottom plate 211 and the side wall 212 together, the side wall 212 is provided with a second through hole 215, and the second through hole 215 is communicated with the chamber 213;

the key is embedded in the second through hole 215;

the first elastic member 120 is located in the cavity 213;

the side key body 140 and the limiting structure 150 are respectively positioned at two sides of the side wall 212 with the second through hole 215; the side key body and the keys are distributed in parallel, and the side key body is positioned on the outer surface of the side wall 212 far away from the central position of the middle frame 210;

when the limiting structure is located at the first position, the key is at least partially located on the outer surface of the side wall with the second through hole 214, which is far away from the central position of the middle frame 110;

when the limiting structure is located at the second position, the key is hidden in the second through hole 215.

In the embodiment of the present disclosure, as shown in fig. 1 to 3, the second through hole 215 is used for the key body 110 of the key to pass through so as to compress the second elastic element 180 in the cavity 213. As shown in fig. 6, a portion of the key body 110 and the side key body 140 are located outside the sidewall 212 having the second through hole 215 for the pressing operation of the user.

In a specific example, the deformation of the first elastic member 120 is 0.5-0.6 mm, the deformation of the second elastic member 180 is 0.4-0.5 mm, and the portion of the key body 110 extending out of the second through hole 215 is approximately 1.0-1.2 mm. Therefore, when the limiting structure is located at the second position, the first acting force is applied to the key body 110, the key body 110 can compress the second elastic element 180 to realize the switching function, the first elastic element 120 is not affected, when the key body 110 needs to be hidden, the pressure is increased to apply the second acting force to the key body 110, at this time, the key body 110 can be flush with the outer surface of the side wall 212, even slightly lower than the outer surface of the side wall 212, and is sunk into the second through hole 215 to realize the hiding of the key body 110. At this time, the side key body 140 can be slid to lock the key by the limiting structure 150.

Without limitation, a terminal includes, but is not limited to, a cell phone, a tablet, a laptop, a television, a display, a gaming console, or a wearable device.

In other alternative embodiments, the sidewall 212 further has thereon: a sliding hole 214, the sliding hole 214 is communicated with the chamber 213 and is distributed with the second through hole 215 in parallel;

the side key body 140 has a protruding pillar 141 protruding toward the position limiting structure 150, and the protruding pillar passes through the sliding hole 214 and is fixed with the position limiting structure 150.

As shown in fig. 1, the length of the sliding hole 214 is parallel to the lateral direction. The side key body 140 is located on the outer surface of the sidewall 212, and the position-limiting structure 150 is located on the inner surface of the sidewall 212. The process of the side key moving in the lateral direction is the process of the convex column 141 moving along the sliding hole 214. The convex column 141 is tightly matched with the sliding hole 214, when the side key body 140 is acted by acting force, the convex column 141 can slide in the sliding hole 214 along the transverse direction, when the acting force is not acted, the convex column 141 cannot slide in the sliding hole 214, the side key can be fixed on the middle frame 110, and then the limiting structure can be fixed at the first position or the second position according to requirements.

In other optional embodiments, the terminal further includes:

a first stopper 220 positioned in the chamber 213, mounted on the base plate 211, and aligned with the second through hole 215, the side key structure being positioned between the first stopper 220 and the sidewall 212 having the second through hole 215;

the first elastic element 120 of the side key structure is located between the first position-limiting portion 220 and the sliding seat 160 of the key, and contacts with the first position-limiting portion 220.

As shown in fig. 1 to 4, the first position-limiting portion 220 and the sliding seat 160 are disposed in parallel along the longitudinal direction, one end of the first elastic element 120 contacts with the sliding seat 160, the other end contacts with the first position-limiting portion 220, and the sliding seat 160 can move along the longitudinal direction relative to the first position-limiting portion 220. Without limitation, both ends of the first elastic element 120 are respectively abutted against the sliding seat 160 and the first limiting portion 220.

In other alternative embodiments, the first position-limiting portion 220 includes: the second position-limiting groove 221 is formed in the first position-limiting groove,
