As shown in fig. 1, 2 and 12, the key structure includes a base 100, a key cap 200, a decoration assembly 400 and a support 300. The base 100 may be a middle frame of an electronic product, and it is understood that only a part of the structure of the base 100 is shown in the figure.

In an embodiment, one side of the base 100 is provided with a mounting hole 101, and the key cap 200 is mounted in the mounting hole 101. It is understood that, in order to facilitate the user to operate the key cap 200, in the electronic product, the mounting hole 101 is disposed at a position close to a side edge of the electronic product on the base 100, and is communicated with the external environment.

The support 300 is installed inside the base 100, and the key cap 200 is connected to the support 300, so that one end of the key cap 200 can be limited in the base 100, and the key cap 200 is prevented from being separated from the base 100. The decoration element 400 is disposed on a side of the support 300 close to the key cap 200, and is disposed corresponding to a gap between the key cap 200 and a sidewall of the mounting hole 101. Therefore, in the installation position of the key cap 200, the decoration assembly 400 can shield the support 300 inside the base 100, i.e. shield the assembly structure inside the key structure, so as to prevent the user from directly seeing the support 300 from the gap between the key cap 200 and the side wall of the installation hole 101. Meanwhile, the decoration assembly 400 can decorate the corresponding part of the support 300, so that the appearance of the installation position of the key structure is improved, correspondingly, the appearance of the electronic product can be improved, the aesthetic feeling is improved, and the user experience can be improved.

Example two

The embodiment provides a key structure which can be used in a mobile phone. Specifically, the key structure can be used as a mobile phone side key to switch the working mode, the switch and the like of the mobile phone. The base 100 may be a part of a middle frame of a mobile phone. It is understood that the present embodiment is further defined on the basis of the first embodiment.

Of course, in other embodiments, the key structure may also be disposed on the front side or the back side of the mobile phone, that is, the side of the mobile phone where the display screen is disposed or the side away from the display screen.

Referring to fig. 3, a first receiving cavity 102 for receiving a bracket 300 is further disposed in the base 100, and the bracket 300 is installed in the first receiving cavity 102. The mounting hole 101 communicates with the first receiving cavity 102 to facilitate the connection of the key cap 200 with the support 300. The first receiving cavity 102 may be a cavity structure with one side open, and the bracket 300 may be installed in the first receiving cavity 102 from the open position. In one embodiment, the opening of the first receiving cavity 102 may be disposed on one side of the base 100 in the thickness direction.

In some specific embodiments, the key cap 200 is slidably mounted in the mounting hole 101, and correspondingly, the support 300 is also slidably mounted in the first receiving cavity 102. The sliding direction of the key cap 200 can be set along the height direction of the key structure, the sliding direction of the support 300 is parallel to the sliding direction of the key cap 200, and the key cap 200 can drive the support 300 to move synchronously when sliding relative to the base 100. It is understood that in normal use of the mobile phone, the mobile phone is generally in a vertical state, and when the key cap 200 slides relative to the base 100, it is understood that the key cap 200 can slide up and down.

In the height direction of the key structure, the opening size of the mounting hole 101 is larger than the height of the key cap 200, so that the key cap 200 can slide in the x-axis direction in the mounting hole 101. The size of the first receiving cavity 102 is larger than the height of the bracket 300, so that the bracket 300 can slide in the x-axis direction in the first receiving cavity 102.

In the thickness direction of the key structure, the size of the mounting hole 101 may be equal to the thickness of the key cap 200, and the key cap 200 may be limited in the z-axis direction. In the width direction of the key structure, the size of the first receiving cavity 102 may be equal to the width of the bracket 300, and the bracket 300 may be limited in the y-axis direction. Therefore, the assembly precision and the operation precision of the key structure can be ensured, and the key structure is ensured to accord with the product standard.

Further, as shown in fig. 2, 4 to 9, the key cap 200 is detachably connected to the support 300. In some embodiments, keycap 200 and support 300 can be coupled by a latch 700.

As shown in fig. 7, key cap 200 may include an actuator 201 and a connector 202 connected thereto. Wherein, the connecting portion 202 is disposed near the bracket 300, and the connecting portion 202 is detachably connected with the bracket 300. The actuator 201 is disposed away from the bracket 300, and the actuator 201 extends to the outside of the base 100, i.e., the outside of the mobile phone, through the mounting hole 101, so as to facilitate the user operation. Therefore, the user can operate the key cap through the executing part 201, and further drive the bracket 300 to synchronously act. In some embodiments, the actuator 201 may be integrally formed with the connecting portion 202.

In other embodiments, the actuating portion 201 and the connecting portion 202 may be separate bodies, and may be fixedly connected by welding, bonding, clipping, screwing, or other connection methods.

In an embodiment, the anti-slip pattern 204 is disposed on a side of the executing portion 201 away from the connecting portion 202, so that when a user operates the key cap 200, a problem of slipping can be avoided.

As shown in fig. 4, 7, 9 and 12, the support 300 is provided with a through hole 301, the through hole 301 extends along the width direction of the key structure, and the connection portion 202 of the key cap 200 is inserted into the through hole 301.

A pair of limiting platforms 305 are disposed on one side of the support 300 close to the key cap 200, and the two limiting platforms 305 are disposed on two sides of the through hole 301 in the height direction of the key structure. The cross-sectional area of the connecting part 202 on the xz plane is smaller than that of the actuating part 201 on the xz plane, the connecting part 202 and the actuating part 201 are coaxially arranged, correspondingly, a step structure is formed at the connecting part of the actuating part 201 and the connecting part 202, a corresponding abutting surface 203 can be formed at one end, close to the connecting part 202, of the actuating part 201, and the abutting surface 203 corresponds to the limiting table 305. When key cap 200 is inserted into through hole 301 of support 300, abutment surface 203 may cooperate with stop 305 to locate the installation of key cap 200, i.e., when abutment surface 203 abuts stop 305, it may indicate that key cap 200 has been installed in place relative to support 300.

Further, the connecting portion 202 is provided with a first insertion hole 2021, and the bracket 300 is provided with a second insertion hole 303 communicating with the through hole 301. After the connecting portion 202 is inserted into the through hole 301, the first insertion hole 2021 and the second insertion hole 303 are coaxial. The plug 700 is inserted into the first insertion hole 2021 and the second insertion hole 303 at the same time, so that the connection between the connection portion 202 and the support 300, that is, the connection between the key cap 200 and the support 300, is realized.

In an embodiment, the second insertion hole 303 at least includes a first step hole 3031, and the first step hole 3031 is disposed on a side of the bracket 300 close to the opening of the first receiving cavity 102. The first step hole 3031 is a through hole, and communicates with the through hole 301. When assembling, the plug 700 can be inserted from the opening side of the first receiving cavity 102 and inserted into the first step hole 3031 and the first inserting hole 2021 in sequence. Correspondingly, the first insertion hole 2021 may be a through hole or a blind hole, and when the first insertion hole 2021 is a blind hole, an open end thereof is disposed at a side close to the first step hole 3031.

In some embodiments, the second insertion hole 303 further includes a second step hole 3032, the second step hole 3032 is disposed at a side of the bracket 300 away from the opening of the first receiving cavity 102, the second step hole 3032 is communicated with the through hole 301, and the second step hole 3032 is coaxial with the first step hole 3031. In an embodiment, the second step hole 3032 may also be a through hole or a blind hole. It will be appreciated that when the second step 3032 is blind, its open end is disposed adjacent to the first step 3031.

In some embodiments, latch 700 may have an inverted U-shape. Accordingly, two pairs of the first insertion hole 2021 and the second insertion hole 303 are provided. Both ends of the latch 700 may be respectively inserted into the corresponding pair of first insertion holes 2021 and second insertion holes 303. It is understood that when the latch 700 is inserted into the connecting bracket 300 and the key cap 200, the arc-shaped bent section of the latch 700 is close to the opening side of the first receiving cavity 102.

As shown in fig. 4 and 8, a limit buckle 304 is further disposed on the support 300, and the limit buckle 304 is used for limiting the latch 700, so as to prevent the latch 700 from being separated from the support 300 and the key cap 200 at will. The position-limiting buckle 304 is disposed on one side of the bracket 300 close to the opening of the first accommodating cavity 102, and is in an inverted hook-shaped structure. Meanwhile, the hook portion 3041 of the position-limiting buckle 304 extends to the connection line between the two second insertion holes 303. It can be understood that, in the width direction of the key structure, a connection line of the two second insertion holes 303 has a certain line width, and a projection of the hook portion 3041 on the xy plane at least partially covers the connection line of the two second insertion holes 303. Therefore, when the pin 700 is inserted into and connected with the bracket 300 and the key cap 200, the hook 3041 can limit the pin 700, and prevent the pin 700 from being separated from the key cap 200 and the bracket 300. In one embodiment, the retaining buckle 304 may be integrally formed with the bracket 300.

In some embodiments, the bracket 300 may be a plastic bracket, so that the bracket 300 has a certain elasticity and can be elastically deformed. Accordingly, the position-limiting buckle 304 may have a certain elasticity, and when the plug 700 is inserted, the position-limiting buckle 304 may be pressed to be elastically deformed, so that the position-limiting buckle 304 may be temporarily deviated from the connection line of the two second insertion holes 303, and the plug 700 may be smoothly inserted into the bracket 300 and the key cap 200. After the plug 700 is inserted into the connecting bracket 300 and the key cap 200, the position-limiting buckle 304 can be released to reset the position-limiting buckle 304, so that the plug 700 can be limited by the position-limiting buckle 304.

In other embodiments, the support 300 may also be a flexible support such as a rubber support, a silicone support, or a resin support.

In other embodiments, the keycap 200 and the support 300 can be locked and connected by screws. Accordingly, the first and

second insertion holes

2021 and 303 may be provided as threaded holes to be fitted with screws.

In other embodiments, keycap 200 and support 300 may be non-removably coupled by gluing or the like. It can be understood that, when the key cap 200 is bonded to the support 300, a corresponding glue dispensing hole may be disposed on a side of the support 300 close to the opening of the first receiving cavity 102, and the glue dispensing hole is communicated with the through hole 301, so as to facilitate injecting glue between the support 300 and the key cap 200.

By providing support 300 as a flexible support, keycap 200 may also be protected. In an embodiment, keycap 200 can be an aluminum keycap, with corresponding structural strength in one aspect. On the other hand, the mobile phone can have certain texture in appearance, and the appearance form of the mobile phone is improved. In use, when the key structure receives the collision, support 300 can absorb the effort that key cap 200 received at the collision in-process, avoids key cap 200 to damage, thereby realizes the protection to key cap 200.

In the prior art, the bracket 300 made of metal is usually selected, and in order to achieve the buffering effect, the bracket 300 needs to be set to have a larger volume so as to meet the required buffering space. In the application, the support 300 is directly arranged as a flexible support, so that the collision acting force can be effectively absorbed, and correspondingly, the size of the support 300 can be reduced, namely, the occupied space of the key structure is reduced, and the light and thin design of the mobile phone is facilitated.

In addition, when the metal support is collided, the metal support generates plastic deformation and cannot be automatically restored, and the key cap 200 is blocked, poor in operation and the like. And in this application, support 300 produces elastic deformation when receiving the collision, can carry out automatic recovery after support 300 takes place elastic deformation to can promote key cap 200 and reset, and then avoid key cap 200 to appear the emergence of the dead, the poor operation scheduling problem of card, with the quality that improves the cell-phone.

Of course, in other embodiments, the key cap 200 may also be made of stainless steel, aluminum alloy, or other metal.

In other embodiments, as shown in fig. 6, the inside of the support 300 may be hollow, which may reduce the weight of the support 300 and the mass of the mobile phone.

Further, as shown in fig. 1, 4, 12 to 14, a side of the bracket 300 near the key cap 200 is provided with a mounting position 302 for mounting the decoration assembly 400. In an embodiment, the trim assembly 400 includes a first trim piece 401 and a second trim piece 402. Accordingly, the mounting location 302 may include a first mounting slot 3021 and a second mounting slot 3022. In the height direction of the key structure, the first mounting groove 3021 and the second mounting groove 3022 are respectively disposed at both ends of the through hole 301, that is, the first mounting groove 3021 and the second mounting groove 3022 are distributed along the sliding direction of the support 300. The first garnish 401 is fitted in the first mounting groove 3021, and the second garnish 402 is fitted in the second mounting groove 3022. That is, the first decoration 401 and the second decoration 402 are provided at both ends of the key cap 200 in the sliding direction of the key cap 200. In an embodiment, the first decoration 401 and the second decoration 402 can be adhered to the corresponding mounting grooves by gluing.

In the thickness direction of the key structure, the size of the first garnish 401 and the size of the second garnish 402 are both equal to or larger than the size of the mounting hole 101. In the height direction of the key structure, when the key cap 200 is slid to one end of the mounting hole 101, the length of the decoration at the opposite end is equal to or greater than the distance from the key cap 200 to the side wall at the other end of the mounting hole 101, i.e., the gap between the key cap 200 and the mounting hole 101 may completely correspond to the decoration at the opposite end. Therefore, when the key cap 200 slides, the support 300 is prevented from being exposed.

In some embodiments, the decoration device 400 may be an aluminum decoration plate, and a surface of the decoration device 400 far from the bracket 300 may be anodized to exhibit a better metal texture. For structures such as plastic, silica gel, the visual effect that decorates subassembly 400 of aluminium system also can promote key cap 200 mounted position improves the outward appearance effect of cell-phone, promotes user experience.

In other embodiments, the decoration assembly 400 may also be made of stainless steel, aluminum alloy, gold, silver, or other metal materials to shield and decorate the bracket 300, so as to prevent the bracket 300 from being exposed, thereby improving the appearance of the key structure.

Further, as shown in fig. 1, 3, 7 and 12, the key structure further includes a resilient positioning member 500 for positioning the keycap 200 relative to the base 100. Correspondingly, one end of the connecting portion 202, which is far away from the executing portion 201, is provided with at least two limiting grooves 205, and the limiting grooves 205 are matched with the positioning assembly 500 to position the keycap 200. In an embodiment, at least two limiting grooves 205 are distributed along the sliding direction of the key cap 200. When the key cap 200 slides relative to the base 100, the positioning element 500 can be switched from one of the position-limiting grooves 205 to another of the position-limiting grooves 205.

In some embodiments, the base 100 further has a second receiving cavity 103 for mounting the positioning assembly 500. The second accommodating cavity 103 is communicated with the first accommodating cavity 102, the second accommodating cavity 103 is arranged opposite to the mounting hole 101, and the second accommodating cavity 103 can be arranged coaxially with the mounting hole 101. The positioning element 500 is installed in the second receiving cavity 103, and an end of the positioning element 500 close to the bracket 300 may protrude from the second receiving cavity 103, so that the positioning element 500 is connected to the limiting groove 205 of the key cap 200 in a matching manner.

In some specific embodiments, the positioning assembly 500 includes a positioning bead 501 and a resilient member 502. The elastic direction of the elastic member 502 is arranged along the width direction of the key structure. The positioning ball 501 abuts against one end of the elastic member 502 close to the bracket 300, the other end of the elastic member 502 abuts against a sidewall of the second accommodating cavity 103 far from one end of the bracket 300, and the elastic member 502 is compressed between the positioning ball 501 and the sidewall. Therefore, the elastic member 502 can push the positioning ball 501 to move towards the direction close to the key cap 200, so that the positioning ball 501 is limited in the corresponding limiting groove 205. It will be appreciated that the retaining groove 205 is shaped to mate with the retaining bead 501. In one embodiment, the resilient member 502 may be a spring and the retaining ball 501 may be a steel ball.

In other embodiments, the elastic member 502 may also be a spring, a flexible block, or the like.

In other embodiments, the positioning assembly 500 may be a pogo pin, a cylindrical flexible block, or the like. It is understood that when positioning assembly 500 is a cylindrical flexible mass, the end of the flexible mass proximate to keycap 200 can be hemispherical.

In some specific embodiments, the key cap 200 is provided with three limiting grooves 205, namely a first limiting groove 2051, a second limiting groove 2052 and a third limiting groove 2053, and the three limiting grooves 205 are arranged along the sliding direction of the key cap 200. The protrusion between two adjacent limiting grooves 205 is provided with a rounded corner to facilitate the positioning component 500 to slide into another limiting groove 205 from one limiting groove 205.

In other embodiments, two, four, five, six, etc. spacing grooves 205 can be disposed on the key cap 200.

Further, as shown in fig. 5 and 10, the key structure further includes a detection assembly 600 for detecting the position of keycap 200 relative to base 100. Specifically, the detecting assembly 600 may include a triggering member 601 and a sensing member 602. Wherein, the trigger 601 can be fixedly arranged on the support 300, so that the trigger 601 can follow the keycap 200 to synchronously act. The sensing element 602 may be fixed relative to the base 100, and specifically, the sensing element 602 may be fixed on a main board of the mobile phone. When the key cap 200 slides relative to the base 100, the triggering part 601 is used for triggering the sensing part 602 to generate a corresponding sensing signal.

In some embodiments, the trigger 601 may be a magnet and the sensing element 602 may be a hall sensor. One side of the support 300 far away from the keycap 200 is provided with a third mounting groove 306, and the magnet is embedded in the third mounting groove 306, so that the magnet can be closer to the hall sensor, and the detection precision is improved. It can be appreciated that the third mounting groove 306 avoids the through hole 301. In an embodiment, two hall sensors may be provided, and the two hall sensors are spaced along the sliding direction of the key cap 200, so that the detection precision of the detection assembly 600 can be improved.

In other embodiments, trigger 601 can also be fixedly disposed on keycap 200. The Hall sensors can also be arranged in one, three, four and the like.

In other embodiments, as shown in fig. 11, the sensing element 602 can be a distance sensor, and correspondingly, the triggering element 601 can be a plurality of grooves with different depths, wherein the number of the grooves can be equal to the number of the limiting grooves 205 on the key cap 200, and the grooves correspond to the limiting grooves 205 one by one. When grooves with different depths correspond to the distance sensor, the distance sensor can be triggered to generate different sensing signals.

When assembling the key structure, the bracket 300 may be first installed in the first receiving cavity 102. And then the positioning assembly 500 sequentially passes through the mounting hole 101 and the through hole 301 on the bracket 300 and is installed in the second accommodating cavity 103. After the positioning assembly 500 is mounted in place, the key cap 200 may be inserted through the mounting hole 101 and into the through hole 301 of the bracket 300, so that the first insertion hole 2021 and the second insertion hole 303 correspond. Then, the pin 700 is inserted and connected to the support 300 and the key cap 200, and the pin 700 is limited by the limit button 304. It is understood that the triggering member 601 can be pre-installed in the third installation groove 306 of the cradle 300, and the sensing member 602 can be pre-installed on the main board of the mobile phone.

In use, the sensing element 602 can be electrically connected to a control unit of the mobile phone, a sensing signal generated by the sensing element 602 can be used as a control signal of the mobile phone, and the control unit in the mobile phone can control the mobile phone to perform corresponding actions according to the received control signal. For example, the control signal can be used for controlling the switching of the reminding mode of the mobile phone.

For example, as shown in fig. 12 to 14, the key structure is schematically illustrated in three use states, a first limiting groove 2051 may correspond to a mute mode of the mobile phone, a second limiting groove 2052 may correspond to a vibration mode of the mobile phone, and a third limiting groove 2053 may correspond to a ring mode of the mobile phone. In use, a user pushes the key cap 200 to position the positioning assembly 500 in different position-limiting grooves 205, so that the key cap 200 is fixed at a corresponding position. The detection component 600 can send a corresponding trigger signal to the control unit according to the position of the keycap 200, and then the control unit controls the mobile phone to switch between a mute mode, a vibration mode or a ring mode.

When the initial state of the mobile phone is in the ring mode, correspondingly, the positioning component 500 can be limited and abutted against the first limiting groove 2051. When the reminding mode of the mobile phone needs to be adjusted to be the vibration mode, the keycap 200 can be pushed downwards relative to the base 100. During the sliding of the key cap 200, the key cap 200 can press the positioning element 500, so that the positioning element 500 is inserted into the second accommodating cavity 103, and the positioning element 500 is separated from the first limiting groove 2051. When the second limiting groove 2052 corresponds to the positioning element 500, the positioning element 500 is repositioned and limited in the second limiting groove 2052. At this time, the detecting component 600 detects the position change of the key cap 200 and sends a corresponding trigger signal to the control unit of the mobile phone, and the control unit controls the mobile phone to switch to the vibration mode according to the received trigger signal.

In other embodiments, the key structure may also be used for switching function modes, such as a switch of a mobile phone, a switch of software, adjustment of volume, adjustment of screen brightness, and the like, without limitation.

In other embodiments, the key cap 200 can also be rotatably installed at the position of the installation hole 101, and correspondingly, the bracket 300 can also be rotatably installed in the first accommodation cavity 102, and correspondingly, the limiting grooves 205 can also be distributed in a ring shape. In an embodiment, the key cap 200 may be disposed coaxially or eccentrically with respect to the frame 300, and when the key cap 200 rotates, the frame 300 may be driven to rotate coaxially or eccentrically, and the positioning element 500 may be switched from one of the position-limiting grooves 205 to another of the position-limiting grooves 205. Accordingly, the position of the triggering element 601 changes along with the rotation of the key cap 200, so that the sensing element 602 generates a corresponding sensing signal. It is understood that trigger 601 may be disposed off-center from keycap 200.

In other embodiments, keycap 200 can be a touch key and keycap 200 can be fixedly mounted relative to base 100. Accordingly, the bracket 300 may also be fixedly installed in the first receiving cavity 102. It will be appreciated that, in use, keycap 200 may be directly electrically connected to a control unit in a cell phone. A user can perform a related operation by touching key cap 200.
