The detailed structures of the frame 100, the key 200, the stopper 300, the elastic element 400 and the fixing member 500, and the connection relationship and the operation principle between the above components according to the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 4, fig. 4 is a schematic structural diagram of a frame 100 according to an embodiment of the present application. The frame body 100 of the embodiment of the present application includes an outer frame part 120 and an inner frame part 140 provided inside the outer frame part 120. The outer frame portion 120 and the inner frame portion 140 may be of unitary construction.

The outer side wall of the outer frame part 120 is provided with a key pressing groove 124, and the key cap 220 of the key 200 is movably received in the key pressing groove 124. When the user does not press the key, part of the key cap 220 is exposed out of the key pressing groove 124. The key slot 124 may be elongated, oval, circular or other shape, and the specific shape of the key slot 124 is adapted to the shape of the key cap 220.

When the key slot 124 is elongated, the key slot 124 includes a bottom surface 1241 and two opposite sidewalls 1242. The bottom surface 1241 of the key slot 124 is provided with two limiting slots 122 and a through hole 126, the two limiting slots 122 are arranged to extend along the X direction, and the through hole 126 is arranged to extend along the X direction. The limiting groove 122 is used for accommodating a limiting member 240 of the key 200, and the through hole 126 is used for allowing a key post 260 of the key 200 to penetrate therethrough. Two retaining grooves 122 may be provided at either end of the key slot 124, with a through hole 126 provided between the two retaining grooves 122, for example, in the middle region of the two retaining grooves 122.

The inner frame section 140 is provided with two first positioning grooves 142 and one second positioning groove 144, each first positioning groove 142 extending in the Z direction, and the second positioning groove 144 extending in the Z direction. One of the first positioning grooves 142 is communicated with one of the limiting grooves 122, and the other first positioning groove 142 is communicated with the other limiting groove 122. The through hole 126 is connected to the second positioning groove 144.

The first positioning groove 142 is used for inserting the stop member 300, and the second positioning groove 144 is used for inserting the fixing member 500. When the stopper 300 is inserted into the first positioning groove 142, at least a portion of the stopper 300 is disposed in the limiting groove 122 and can stop the limiting member 240, so as to prevent the key 200 from falling off from the frame 100. A slot 1421 may be disposed on a wall of the first positioning slot 142, and the slot 1421 is used to cooperate with the protrusion 340 of the stopper 300 to implement clamping. Of course, a protrusion may be disposed on a wall of the first positioning groove 142, and the protrusion is used to cooperate with the slot of the stop member 300 to realize the clamping. Similarly, the groove wall of the second positioning groove 144 is also connected to the fixing member 500 through a clamping structure, for example, a protrusion or a slot is formed on the groove wall of the second positioning groove 144.

As shown in fig. 5 and 6, fig. 5 is a schematic structural view of a stopper 300 according to an embodiment of the present application, and fig. 6 is a schematic structural view of a stopper 300 according to an embodiment of the present application from another perspective. The stopper 300 may be substantially in the form of a plate, may be made of plastic, and may be injection molded. One side of the stopper 300 has a stopping surface 320, and the stopping surface 320 is used for abutting against the stopper 240 of the key 200 to stop the key from moving outwards along the X direction.

The sidewall of the stopper 300 is provided with a protrusion 340, and the protrusion 340 is used for being engaged with a locking groove 1421 provided on the wall of the first positioning groove 142. Of course, the side wall of the stopper 300 may also be provided with a locking groove for locking with the protrusion on the wall of the first positioning groove 142.

The sidewall of the stopper 300 may further have an interference structure 360, so that when the stopper 300 is inserted into the first positioning groove 142, the stopper 300 and the first positioning groove 142 may be in interference fit, thereby preventing the stopper 300 from shaking.

As shown in fig. 7, fig. 7 is a schematic structural diagram of a key according to an embodiment of the present application. The key of the embodiment of the present application includes a key cap 220, two position limiters 240, and a key post 260.

The key cap 220 may have a rectangular parallelepiped shape, but may also have a cylindrical shape or other shapes. The two limiting members 240 and the key post 260 are disposed on one side of the key cap 220, the two limiting members 240 are disposed on two ends of the key cap 220, and the key post 260 is disposed between the two limiting members 240, for example, the key post 260 is disposed in a middle region of the two limiting members 240.

Each of the position-limiting members 240 includes a main body 242 and a position-limiting portion 244, the main body 242 is connected to one side of the keycap 220 facing the frame 100, and the position-limiting portion 244 is connected to the main body 242 and protrudes from a side surface of the main body 242 to form an L shape. The extending direction of the position-limiting part 244 with respect to the main body 242 is not particularly limited in the embodiment of the present application, and for example, the position-limiting part 244 may be protruded from the side surface of the main body 242 along the Z direction, or may be protruded from the side surface of the main body 242 along a direction perpendicular to the Z direction and the X direction.

In the present embodiment, as shown in fig. 7, the two position-limiting portions 244 of the two position-limiting members 240 extend in a direction away from the key post 260. Of course, both of the limiting portions 244 may extend toward the key post 260, or one of the limiting portions 244 extends away from the key post 260 and the other limiting portion 244 extends toward the key post 260.

Each of the position-limiting portions 244 has a position-limiting surface 2441 facing the key cap 220, and the position-limiting surface 2441 is used for abutting against the stop surface 320 of the stop member 300 to stop the key from moving out of the frame 100 along the X direction.

It can be understood that the key cap 220 and the position limiting member 240 can be integrally formed, so as to avoid the inconvenience of assembling due to disassembling into multiple parts.

It is understood that the key cap 220 and the key post 260 can be integrally formed; alternatively, the key cap 220, the limiting member 240 and the key post 260 may be integrally formed, so as to avoid the inconvenience of assembling due to disassembling into multiple parts.

The keycap 220 is provided with two blind holes 222 at a side facing the frame 100, and the blind holes 222 are used for connecting an elastic element 400. One of the blind holes 222 is disposed between one of the position-limiting members 240 and the key post 260, and the other blind hole 222 is disposed between the other one of the position-limiting members 240 and the key post 260.

The lateral wall of the key post 260 is provided with the annular groove 264, and the annular groove 264 is used for connecting a second sealing member 700, so that when the key post 260 is penetrated through the through hole 126, the second sealing member 700 can be sealed between the lateral wall of the key post 260 and the hole wall of the through hole 126, thereby preventing water vapor and dust from entering the frame body 100 through the through hole 126 and playing a role in water and dust prevention. The second sealing member 700 can be a sealing ring, which is disposed outside the key post 260 and partially received in the annular groove 264.

An end of key post 260 remote from key cap 220 is further provided with a connecting slot 262, where connecting slot 262 is used to connect a contact pad 800, and contact pad 800 may be made of a flexible material, such as thermoplastic polyurethane elastomers (TPU). The key post 260 triggers a tact switch 620 through the contact pad 800, so as to prevent the tact switch 620 from being damaged by the direct contact of the key post 260 with the tact switch 620.

Of course, it is understood that the number of the above-mentioned limiting members and key posts can be changed as follows: the key includes a key cap 220, a limiting member 240 and two key posts 260, wherein the limiting member 240 and the two key posts 260 are disposed on one side of the key cap 220, the two key posts 260 can be disposed on two ends of the key cap 220, the limiting member 240 is disposed between the two key posts 260, for example, the limiting member 240 is disposed in a middle region of the two key posts 260. Two key posts 260 can activate two tact switches 620, respectively, to achieve different functions. For example, when the key is a volume key of a mobile phone, one of the key columns 260 may implement a volume increasing function, and the other key column 260 may implement a volume decreasing function.

The difference between the limiting member 240 of the present embodiment and the limiting member of the previous embodiment is: the position limiting member of the present embodiment includes a main body 242 and two position limiting portions 244, wherein the two position limiting portions 244 are respectively connected to the main body 242 and respectively protrude from the side surface of the main body 242. The two position limiting portions 244 may extend in directions away from each other in a direction perpendicular to the X-direction and the Z-direction so that the two position limiting portions 244 can be engaged with the two stoppers 300, respectively.

Of course, it is understood that the two limiting portions 244 provided on the main body 242 may be aligned in the X direction or may be staggered.

Fig. 8 is a schematic structural view of a housing assembly according to an embodiment of the present application, as shown in fig. 8 and 9, and fig. 9 is a partially enlarged view of a portion a in fig. 8. The position limiting member 240 has a position limiting surface 2441, the stop member 300 has a stop surface 320, and the position limiting surface 2441 and the stop surface 320 are disposed opposite to each other and can abut against each other.

When the user does not press the key cap 220, the key cap 220 tends to move away from the frame 100 due to the elastic element 400, and the stop surface 320 abuts against the limit surface 2441, so that the stop member 300 can stop the key cap 220 from moving outward from the frame 100 along the X direction, and prevent the key from falling off the frame 100. When the user presses the key cap 220, the stopper 240 moves inward toward the frame 100 along the X direction, and at this time, the stopper surface 2441 is separated from the stopper surface 320 and moves inward toward the frame 100. When the key is restored from the pressed state to the unstressed state, the limiting surface 2441 gradually approaches the stop surface 320 until the limiting surface abuts against the stop surface 320, and the key cannot move continuously.

Referring to fig. 10, fig. 10 is a schematic structural diagram of an elastic element 400 according to an embodiment of the present disclosure. The elastic element 400 of the embodiment of the application is disposed in the key pressing groove 124, one end of the elastic element 400 abuts against the key cap 220, and the other end of the elastic element 400 abuts against the bottom 1241 of the key pressing groove 124, so that the key cap 220 tends to be away from the frame 100.

The elastic member 400 is made of an elastic material, and includes a connection portion 420 and a deformation portion 440. The elastic material may be rubber or other material having elasticity. The connecting portion 420 may be a column and is adhered to the blind hole 222 of the key cap 220. The deformation portion 440 includes a circular truncated cone section 442 and a cylindrical section 444, the circular truncated cone section 442 includes a circular truncated cone upper bottom surface, a circular truncated cone lower bottom surface, and a circular truncated cone side surface disposed between the circular truncated cone upper bottom surface and the circular truncated cone lower bottom surface, and the cylindrical section 444 includes a cylindrical upper bottom surface, a cylindrical lower bottom surface, and a cylindrical side surface disposed between the cylindrical upper bottom surface and the cylindrical lower bottom surface. The upper bottom surface of the circular truncated cone section 442 is connected to the connecting portion 420, and the lower bottom surface of the circular truncated cone section 442 is overlapped with the upper bottom surface of one of the cylinders of the cylinder section 444.

The deformation 440 also includes two oppositely disposed cut surfaces 446, each cut surface 446 being formed on a side of the cylindrical section 444 and a side of the partial frustum section 442. The two cut surfaces 446 abut against two oppositely disposed sidewalls 1242 of the key slot 124, respectively.

The deformation portion 440 further includes a recess 448, and the recess 448 is formed on the other bottom surface of the cylindrical section 444. Another bottom surface of the cylindrical section 444 is further provided with a notch 447, the notch 447 penetrates through the tangent plane 446 and the inner wall of the recessed portion 448 to communicate the inside and the outside of the recessed portion 448, so that when the elastic element 400 is compressed, the air in the recessed portion 448 can be discharged in time, the outside air can also enter the recessed portion 448 in time, and pressure resistance is prevented from existing in the recessed portion 448, which causes reduction of the elastic force of the elastic element 400 and affects the experience of pressing the key by the user.

As shown in fig. 11, fig. 11 is a partial top view of a housing assembly according to an embodiment of the present application. When the user does not press the key, an elastic force is generated between the key cap 220 and the bottom 1241 of the key slot 124 due to the elastic element 400, so that the key tends to move outward of the housing 100 along the X direction. Meanwhile, the stopper 300 can stop the stopper 240, so that the key 200 is prevented from moving out of the frame 100 in the X direction. Through the combined action of the elastic element 400, the stop member 300 and the limiting member 240, the key has no looseness, and the anti-shaking effect is achieved in the X direction.

FIG. 12 is a partial side view of the housing assembly of an embodiment of the present application, as shown in FIG. 12, wherein only a portion of the key cap 220 is shown in FIG. 12 in order to show that the resilient element 400 is not obscured by the key cap 220. As can be seen from the above description of the deformation portion 440, the deformation portion 440 includes the circular truncated cone segment 442 and the cylindrical segment 444, and the deformation portion 440 forms a horn-shaped structure, so that the area of the deformation portion 440 contacting the bottom surface 1241 of the key slot 124 is larger, thereby increasing the friction force between the deformation portion 440 and the frame 100. Further, since the two cut surfaces 446 of the deformable portion 440 can be brought into contact with the two side walls 1242 of the key receiving groove 124, the deformable portion 440 can be stably provided in the key receiving groove 124 in the Z direction. Through the design, the key can achieve the anti-shaking effect in the Z direction.

As shown in fig. 13 and 14, fig. 13 is a schematic structural view of a fixing member 500 according to an embodiment of the present application, and fig. 14 is a schematic structural view of a fixing member 500 according to an embodiment of the present application from another perspective.

The fixing member 500 is detachably inserted into the second positioning groove 144 of the frame 100 to mount the switch assembly 600 on the frame 100.

The fixing member 500 of the embodiment of the application is substantially a U-shaped structure, and includes a clamping portion 520 and two oppositely disposed extension portions 540, and the two extension portions 540 are respectively connected to two ends of the clamping portion 520. One side of the fixture 500 is provided with a boss 522 and two oppositely disposed ledges 542. The boss 522 is disposed on the clamping portion 520, and is configured to be clamped and engaged with a groove wall of the second positioning groove 144, and the two surrounding barriers 542 are disposed on the two extending portions 540 respectively. The boss 522 and the two surrounding barriers 542 surround a clamping space 510, and the clamping space 510 is used for clamping a flexible circuit board 660 of the switch assembly 600.

The shroud 542 includes a first side rail section 5421 and a second side rail section 5422. The extension 540 includes adjacent first and second sides, with a first side stop section 5421 provided on the first side and a second side stop section 5422 provided on the second side. The first side rail segment 5421 may be substantially perpendicular to the second side rail segment 5422.

The other side of the fixing member 500 is provided with an interference structure 550, so that after the fixing member 500 is inserted into the second positioning groove 144, the fixing member 500 and the second positioning groove 144 can be in interference fit, and the fixing member 500 is prevented from shaking.

The two extending portions 540 and the fastening portion 520 surround an opening 530, the opening 530 is used for the key post 260 to penetrate through, and when the user presses the key cap 220, the key post 260 can pass through the opening 530 to trigger the tact switch 620.
