Description

Technical Field

[0001] The utility model relates to the technical field of side keys, and particularly relates to a side key device and an electronic device. Background Art

[0002] Side keys are important components assembled on the side wall of an electronic device, usually including a power button, a volume button, etc., and are used to realize the interaction function between the user and the electronic device. Its design feature is that it can be penetrated through the side wall along the wall thickness direction of the side wall and move into the electronic device, and the circuit is conducted by pressing the switch of the side key circuit board inside, so as to realize specific side key functions.

[0003] In the prior art, the conventional designs of side keys mainly include the following four forms: (1) Hanging platform / hot-melt side keys: The structure is single, and only provides protection below IP54. (2) P+R integrated side keys: The side key and the soft rubber are made into one body by secondary injection molding. The soft rubber is an O-ring, and its waterproof function is realized by the interference with the side wall. However, this design has a poor feel, and the interference between the soft rubber part and the side wall may cause difficulty in assembly. (3) P+R separated side keys: The soft rubber part is made into an O-ring and assembled with the hard rubber, and the waterproof function is also realized by interfering with the side wall. During the assembly process, the rubber ring is easy to turn over and twist, and the feel adjustment is more difficult. (4) Keycap + ejector rod (including O-ring) side keys: The ejector rod is made of metal, and the O-ring mostly uses liquid silicone. Its cost is high, and there are many structural parts, and the cumulative tolerance is large, which also results in a poor feel. In addition, in the way of using the O-ring for waterproof sealing, the O-ring is easily affected by factors such as environmental temperature, service time, and the number of presses, and gradually ages or deforms. When the O-ring ages or deforms, its original sealing performance will be greatly reduced, and it cannot effectively prevent the infiltration of water vapor, resulting in a decline in the waterproof performance of the electronic device, which may damage the internal components and affect the normal operation and service life of the device. Summary of the Utility Model

[0004] One of the purposes of the utility model is to provide a side key device, which can form an effective waterproof barrier, reduce the complexity of the side key structure, improve the assembly efficiency of the side key, and effectively prevent external water vapor from entering the interior of the electronic device.

[0005] In order to achieve the above purpose, the utility model provides a side key device, including:

[0006] A side key, the side key includes a first cylinder;

[0007] A waterproof assembly structure for buckling the side key. The waterproof assembly structure includes a waterproof component and a soft conductive base. The waterproof component is provided with a through hole penetrating the wall thickness. The soft conductive base is fixed on the inner side surface of the waterproof component to seal the through hole. The first cylinder movably penetrates through the through hole and is used to push a part of the soft conductive base to move when the side key is acted on by an external force. After the external force disappears, the soft conductive base resets the side key.

[0008] Further, the side key further includes a clamping member;

[0009] The waterproof component is provided with a fitting groove, and the fitting groove and the clamping member are snap-connected to fix the side key on the waterproof assembly structure.

[0010] Further, the clamping member includes a second cylinder and a first hook formed on the second cylinder;

[0011] A second hook for clamping with the first hook is formed on the groove wall of the fitting groove, and the second hook is used to prevent the side key from disengaging from the waterproof component along the wall thickness direction.

[0012] Further, the fitting groove also penetrates through the inner side surface of the waterproof component along the wall thickness direction, and a sealing portion for sealing the fitting groove is fixed on the inner side surface.

[0013] Further, the sealing portion is configured as a rigid sealing sheet, and the rigid sealing sheet is adhered to the inner side surface of the waterproof component.

[0014] Further, the soft conductive base is made of rubber, silica gel or silicone rubber.

[0015] Further, a first limiting groove is provided at a position corresponding to the through hole on the inner side surface of the waterproof component. The bottom wall of the first limiting groove is communicated with the through hole, and the soft conductive base is fixed in the first limiting groove.

[0016] Another object of the present invention is to provide an electronic device, which can effectively prevent external water vapor from entering the interior of the electronic device.

[0017] In order to achieve the above object, the present invention also provides an electronic device, including the side key device described above.

[0018] Further, it further includes a housing and a circuit board. The waterproof component and the housing are of an integral structure. When the side key is acted on by an external force, the first cylinder pushes a part of the soft conductive base to move to conduct the circuit on the circuit board.

[0019] Further, it further includes a housing and a circuit board. The waterproof component is disposed inside the housing. The housing is provided with a receiving groove, and the side key passes through the receiving groove and is connected to the waterproof component. When the side key is subjected to an external force, the first cylinder pushes a part of the soft conductive base to move to conduct the circuit on the circuit board.

[0020] The side key device and the electronic device of the present invention have the following beneficial effects: (1) The conductive base is configured as a soft conductive base, which is blocked inside the through hole to form an effective waterproof barrier to prevent external water vapor from penetrating into the electronic device from the side key. (2) The first bonding surface of the soft conductive base is bonded to the inner side surface of the first cylinder. The soft conductive base utilizes its excellent elastic deformation characteristics to evenly transfer the pressing force to the switch of the side key circuit board, so that the circuit of the side key circuit board is conducted to achieve the purpose of pressing the side key. (3) The flexible performance of the soft conductive base can improve the user's operation feel and enhance the user experience. (4) The second hook of the matching groove cooperates with the soft conductive base to limit the side key in the inner and outer directions of the waterproof component: when the side key is not pressed, the soft conductive base abuts against the inner side surface of the first cylinder, and the second hook abuts against the outer side surface of the first hook to limit the position of the side key in the inner and outer directions and prevent the side key from moving along the wall thickness direction of the waterproof component when not pressed. (5) By respectively blocking the through hole and the matching groove with the soft conductive base and the seal, it effectively prevents water vapor from penetrating into the electronic device. (6) After the side key is assembled on the waterproof component, there is no need to additionally provide an O-ring in the through hole to achieve the waterproof purpose. This design not only simplifies the assembly process, reduces the assembly difficulty, reduces the manufacturing cost, but also avoids the risk of reduced waterproof effect caused by problems such as aging and deformation of the O-ring, significantly improving the waterproof performance and user experience of the electronic device. (7) When the electronic device is configured with a middle frame and a housing, a waterproof layer is arranged between the second side wall and the first side wall, and the waterproof layer is arranged around the outer periphery of the key to further block external water vapor from entering the interior of the electronic device from the gap between the second side wall and the first side wall.

Herein, in conjunction with Figure 1 , Figure 2 , Figure 3 and Figure 4 the side key device A is exemplarily described to more clearly show each component and the cooperation relationship of the side key device A. It should be understood that although the following Figure 1 , Figure 2 , Figure 3 and Figure 4 show this specific implementation manner as an example and describe it in detail, but the scope of the side key device A of the present utility model is not limited to this specific implementation manner. Except for the components solving the necessary technical problems of the present utility model, the remaining components can be regarded as non-essential technical elements. These non-essential technical elements can be replaced by other technical elements with the same or similar functions or structures in other implementation manners, or alternatively, these non-essential technical elements may not be required in other implementation manners.

[0029] Figure 1 , Figure 2 and Figure 3In the illustrated embodiment, the side key device A is disposed on the housing B of the electronic device, such as on the side wall. Hereinafter, the case where the side key device A is disposed on the side wall of the electronic device will be taken as an example for exemplary description. Hereinafter, for the convenience of more clearly and briefly describing the technical solution, after the side key device A is assembled on the side wall, the direction towards the inside of the electronic device along the wall thickness direction of the side wall is called the inward direction, and the inner side surfaces are all called inner side surfaces. On the contrary, they are all called the outward direction and the outer side surfaces. Thus, there are the inner side surface and the outer side surface of the waterproof component 200, the inner side surface and the outer side surface of the side wall, and so on.

[0030] The side key device A includes a side key 100 and a waterproof assembly structure A1 for clamping the side key 100. The side key 100 includes a first cylinder 120. The waterproof assembly structure A1 includes a waterproof component 200 and a soft conductive base 130. The waterproof component 200 is provided with a through hole 210 penetrating the wall thickness. The soft conductive base 130 is fixed on the inner side surface of the waterproof component 200 to seal the through hole 210. The first cylinder 120 movably penetrates through the through hole 210 and is configured to, when the side key 100 is subjected to an external force, the first cylinder 120 pushes a part of the soft conductive base 130 to move, and after the external force disappears, the soft conductive base 130 resets the side key 100. Preferably, the side key 100 further includes a clamping member 140; correspondingly, the waterproof component 200 is provided with a mating groove 220, and the mating groove 220 and the clamping member 140 are snap-connected to fix the side key 100 on the waterproof assembly structure A1.

[0031] The side key 100 further includes a key cap 110. The key cap 110 is used for assembling the first column 120 and the clamping member 140, and is also used for receiving the pressing of an operator after the side key device A is installed on an electronic device. The key cap 110 is assembled at the waterproof component 200 and exposed on the outer side surface of the waterproof component 200. The key cap 110 is generally configured in a long strip shape (such as a rectangle, an ellipse, etc.). When the key cap 110 is assembled at the waterproof component 200, the length direction of the key cap 110 is distributed along the length direction of the waterproof component 200. The key cap 110 is used for receiving the pressing force from the operator and moving inward along the wall thickness direction of the waterproof component 200 based on the pressing force, so as to drive the first column 120 to move inward and press the soft conductive base 130. After being pressed by the first column 120, the soft conductive base 130 elastically deforms inward, thereby transmitting the pressing force to the switch of the side key circuit board 300 inside. After the switch is stressed, the circuit of the side key circuit board 300 is turned on. The side key circuit board 300 is generally configured as a flexible printed circuit board (Flexible Printed Circuit Board, abbreviated as FPC).

[0032] The number of the first columns 120 is set according to the functional positioning of the side key 100. For example, when the side key 100 is configured as a power button of an electronic device (such as a handheld phone), the first column 120 can be configured as one, which is arranged opposite to the side key circuit board 300 inside the electronic device. When the side key 100 is configured as a volume button of an electronic device, the first column 120 can be configured as two, which are respectively arranged opposite to the switches of the two side key circuit boards 300 inside the electronic device. In this embodiment, the first column 120 is configured as one, which is vertically arranged on the inner side surface of the key cap 110, and the first column 120 is located at the central position of the inner side surface.

[0033] The clamping member 140 and the first cylinder 120 are both disposed on the inner side surface of the keycap 110. In a state of being clamped with the engaging groove 220, it can move a preset distance in the thickness direction of the waterproof component 200 into the electronic device, so that both the keycap 110 and the first cylinder 120 can move a preset distance into the electronic device (i.e., the partial movement described above). The clamping member 140 can be one or more. In the illustrated embodiment, the clamping member 140 is configured to be two, and the two clamping members 140 are vertically disposed on the inner side surface of the keycap 110, and the two clamping members 140 are respectively disposed at both ends of the keycap 110. Those skilled in the art can understand that the arrangement manner of the clamping member 140 is not limited to the arrangement manner described above. In other embodiments, the clamping member 140 can also be arranged on the inner side surface of the keycap 110 in a manner other than the vertical arrangement manner, or the clamping member 140 is not limited to being arranged on the inner side surface of the keycap 110.

[0034] Each of the clamping members 140 includes a second cylinder 141 and a first hook 142 disposed on the second cylinder 141. One end (outer end) of each of the second cylinders 141 is vertically connected to the inner side surface of the keycap 110, and the other end (inner end) extends in a direction away from the other second cylinder 141 to form the first hook 142. Preferably, the first hook 142 has a first inclined guide surface 142a that extends obliquely from the inner end of the second cylinder 141 in a direction away from the other clamping member 140 and toward the keycap 110, a first vertical guide surface 142b that extends from the first inclined guide surface 142a in a direction perpendicular to the inner side surface and toward the keycap 110 (outward), and a first clamping surface 142c that extends from the first vertical guide surface 142b toward the cylindrical surface of the second cylinder 141.

[0035] The soft conductive base 130 is bonded to the side surface of the first cylinder 120 away from the keycap 110. The soft conductive base 130 is configured to be bonded to the inner side surface of the waterproof component 200 and to block the through hole 210, thereby preventing external water vapor from entering. The soft conductive base 130 has a first bonding surface 131 and a contact surface 132. The first bonding surface 131 is used to bond to the inner side surface of the waterproof component 200 and seal the through hole 210, and the first bonding surface 131 is also used to bond to the inner side surface (the side surface away from the keycap 110) of the first cylinder 120 that movably penetrates through the through hole 210 to receive the pressing force from the keycap 110; the contact surface 132 is used to contact the switch of the side key circuit board 300 in the electronic device after the side key device A is installed on the housing B, so as to transfer the pressing force to the switch of the side key circuit board 300 based on its own elastic deformation, thereby turning on the circuit of the side key circuit board 300.

[0036] The soft conductive base 130 can be made of rubber, silica gel, silicone rubber, etc. The core requirement is that when the contact surface 132 of the soft conductive base 130 is in contact with or infinitely close to the switch, under the action of the inward pressing force of the side key 100, the pressing force can be transferred to the switch of the side key circuit board 300 and the switch can be turned on, thereby turning on the circuit of the side key circuit board 300. Therefore, parameters such as the material, elastic deformation, and size of the soft conductive base 130 need to meet the above core requirements.

[0037] Please continue to refer to Figure 1 , the waterproof assembly structure A1 of the present utility model includes the above-mentioned waterproof component 200 and the soft conductive base 130. An accommodation groove 230 for accommodating the keycap 110 is provided on the outer side of the waterproof component 200. A mating groove 220 for engaging with the clamping member 140 and a through hole 210 for the first cylinder 120 to movably penetrate through are provided on the waterproof component 200. The accommodation groove 230 can be provided on the outer side surface of the waterproof component 200 and penetrate through the outer side surface of the waterproof component 200 along the wall thickness direction of the waterproof component 200. The accommodation groove 230 can also be separately provided from the waterproof component 200 and provided on a side wall (such as the second side wall 20b described below) located outside the waterproof component 200. In this way, the accommodation groove 230 penetrates through the second side wall 20b along the wall thickness direction (as Figure 4 shown).

[0038] The through hole 210 is disposed opposite to the first column 120 and penetrates the waterproof component 200 along the wall thickness direction of the waterproof component 200. A bonding area for bonding with the first bonding surface 131 of the soft conductive base 130 is formed on a part of the inner side surface of the waterproof component 200 around the outer periphery of the through hole 210. The soft conductive base 130 is bonded to the bonding area to seal the through hole 210 from the inner side direction of the waterproof component 200, and transfer the pressing force of the side key 100 to the switch of the side key circuit board 300 based on its own elastic deformation, so that the circuit of the side key circuit board 300 is turned on. Preferably, a first limiting groove 261 for accommodating the soft conductive base is provided at a position corresponding to the through hole 210 on the inner side surface of the waterproof component 200 (the bottom surface of the first limiting groove 261 is the above-mentioned bonding area). The first limiting groove 261 is coaxially communicated with the through hole 210 and penetrates inwardly through the inner side surface of the waterproof component 200. The contact surface 132 of the soft conductive base protrudes inwardly from the first limiting groove 261 and contacts the switch of the side key circuit board 300. The inner diameter of the outer end of the through hole 210 is configured to gradually increase outward to form an open structure 211, so as to facilitate the rapid insertion of the first column 120 into the through hole 210.

[0039] The fitting groove 220 is formed at a position on the waterproof component 200 corresponding to the clamping member 140, and the fitting groove 220 is formed by opening inward from the outer side surface of the waterproof component 200 along the wall thickness direction of the waterproof component 200. Specifically, the fitting groove 220 is formed by opening inward from the bottom surface of the receiving groove 230.

[0040] The fitting groove 220 is configured to be two fitting grooves 220 corresponding to the two clamping members 140 described above one by one, and the two fitting grooves 220 are respectively provided at both ends of the waterproof component 200. A second hook 221 for clamping the first hook 142 of the clamping member 140 is formed on the groove wall of each fitting groove 220, so as to prevent the side key 100 from disengaging from the waterproof component 200 outward along the wall thickness direction. The dimension of the second hook 221 in the wall thickness direction is smaller than the length of the second column 141, so that when the first hook 142 is clamped at the second hook 221, the clamping member 140 can move a preset distance inward along the wall thickness direction of the waterproof component 200 into the electronic device.

[0041] Preferably, the second hook 221 has a second inclined guide surface 221a that inclines inward and toward the center of the fitting groove 220 from the outer end of the groove wall of the fitting groove 220, a second vertical guide surface 221b that extends inward along a vertical direction perpendicular to the inner side surface from the second inclined guide surface 221a, and a second clamping surface 221c that extends horizontally from the second vertical guide surface 221b toward the groove wall of the fitting groove 220. The dimension of the second hook 221 in the wall thickness direction described above refers to the vertical distance from the outer side surface (the bottom surface of the receiving groove 230) of the waterproof component 200 to the second clamping surface 221c, and this vertical distance is less than the length (predetermined distance) of the second cylinder 141. When the first clamping surface 142c abuts against the second clamping surface 221c, there is the predetermined distance between the inner side surface of the keycap 110 and the outer side surface (i.e., the bottom surface of the receiving groove 230) of the waterproof component 200, so that when the keycap 110 is pressed, the keycap 110 can move inward by the predetermined distance.

[0042] Please continue to refer to Figure 3 , when the clamping member 140 is clamped in the fitting groove 220, first insert the first inclined guide surface 142a along the second inclined guide surface 221a. At this time, the clamping member 140 is extruded by the first inclined guide surface 142a toward the first cylinder 120; then, insert the first vertical guide surface 142b along the second vertical guide surface 221b; finally, when the first vertical guide surface 142b is located inside the second vertical guide surface 221b in the wall thickness direction, the clamping member 140 returns to its original position so that the first clamping surface 142c is parallel and located inside the second clamping surface 221c, thereby being unidirectionally limited outward by the second clamping surface 221c to prevent the clamping member 140 from disengaging from the fitting groove 220 outward. The unidirectional inward limit of the side key 100 is achieved by the first bonding surface 131 of the soft conductive base 130 described above. By bonding the first cylinder 120 to the first bonding surface 131, when the keycap 110 is not pressed, the keycap 110 will not easily move inward. That is, when the keycap 110 is in an unloaded state, the keycap 110 is restricted by the soft conductive base 130 and cannot move inward, and the first clamping surface 142c of the clamping member 140 of the keycap 110 abuts against the second abutting surface, so that the keycap 110 cannot move outward.

[0043] In the illustrated embodiment, for the convenience of processing and manufacturing and to reduce the process difficulty, the mating groove 220 also penetrates the inner side surface of the waterproof component 200 along the wall thickness direction of the waterproof component 200. To prevent water vapor from entering the inner side of the waterproof component 200, a sealing portion for sealing the mating groove 220 is provided at the inner side surface of the waterproof component 200, and the sealing portion can be fixed to the inner side surface of the waterproof component 200 by any existing fixing method. Preferably, the sealing portion can be configured as a rigid sealing sheet 250 (such as a PC sheet made of PC material), and the rigid sealing sheet 250 has a second bonding surface for bonding to the inner side surface of the waterproof component 200, and the second bonding surface is bonded to the inner side surface of the waterproof component 200. Preferably, a second limiting groove 262 for accommodating the sealing portion is provided at the inner side surface of the first side wall 20a corresponding to the position of the mating groove 220, the second limiting groove 262 is coaxially communicated with the mating groove 220 and penetrates the inner side surface of the waterproof component 200 inwardly.

[0044] In summary, the assembly process of the side key device A of this embodiment is as follows: (1) Bond the soft conductive base 130 to the first limiting groove 261; (2) Pass the first cylinder 120 and the clamping member 140 through the through hole 210 and the mating groove 220 respectively; wherein, after the first cylinder 120 passes through the through hole 210, it is bonded to the soft conductive base 130; after the clamping member 140 passes through the mating groove 220, it is clamped with the mating groove 220.

[0045] The side key device A of this embodiment has the following beneficial effects: (1) The conductive base is configured as a soft conductive base 130, which is sealed inside the through hole 210 to form an effective waterproof barrier to prevent external water vapor from penetrating into the electronic device from the side key 100. (2) The first bonding surface of the soft conductive base 130 is bonded to the inner side surface of the first column 120. The soft conductive base 130 uses its excellent elastic deformation characteristics to evenly transfer the pressing force to the switch of the side key circuit board 300, so that the circuit of the side key circuit board 300 is turned on to achieve the purpose of pressing the side key 100. (3) The flexible performance of the soft conductive base 130 can improve the user's operation feel and user experience. (4) The second hook 221 of the mating groove 220 and the soft conductive base 130 cooperate with each other to limit the side key 100 in the inner and outer directions of the waterproof component 200: when the side key 100 is not pressed, the soft conductive base 130 abuts against the inner side surface of the first column 120, and the second hook 221 abuts against the outer side surface of the first hook 142 to limit the position of the side key 100 in the inner and outer directions and prevent the side key 100 from moving along the wall thickness direction of the waterproof component 200 when not pressed. (5) By using the soft conductive base 130 and the seal to block the through hole 210 and the mating groove 220 respectively, water vapor infiltration into the electronic device is effectively prevented. (6) After the side key 100 is assembled on the waterproof component 200, there is no need to additionally install an O-ring in the through hole 210 to achieve the waterproof purpose. This design not only simplifies the assembly process, reduces the assembly difficulty, reduces the manufacturing cost, but also avoids the risk of reduced waterproof effect caused by problems such as aging and deformation of the O-ring, significantly improving the waterproof performance and user experience of the electronic device.

[0046] Please refer to Figure 4 , Figure 5 and Figure 6 , the present utility model also discloses an electronic device, which includes but is not limited to communication terminals, game consoles, multimedia devices, portable computers, tablets, shooting devices, etc. The communication terminal includes but is not limited to mobile terminals (such as handheld telephones), tablets with communication functions, wearable devices with communication functions (such as wrist-worn devices), etc. The electronic device includes a housing B, a circuit board (not shown in the figure), and the side key device A formed at the housing B. The waterproof component 200 of the side key device A can be integrally formed on the housing B to form an integral structure with it. When the side key 100 is subjected to an external force, the first column 120 pushes a part of the soft conductive base 130 to move to turn on the circuit on the circuit board. The waterproof component 200 can also be arranged inside the housing B. Based on this, the receiving groove 230 of the waterproof component 200 can be configured on the housing B, so that the side key 100 passes through the receiving groove 230 to be connected to the waterproof component 200.

[0047] In this embodiment, taking a tablet as an example of an electronic device, the distribution position of the waterproof component 200 is described exemplarily. The tablet includes a middle frame and a housing B covering the outside of the middle frame, and the circuit board is disposed on the middle frame. The middle frame has a first side wall 20a, and the housing has a second side wall 20b covering the outside of the first side wall 20a, and the first side wall 20a and the second side wall 20b are stacked together from the inside to the outside.

[0048] The through hole 210, the fitting groove 220, the first limiting groove 261, and the second limiting groove 262 of the waterproof component 200 are integrally formed at the middle frame. Specifically, a convex block 201 is formed on the outer side surface of the first side wall 20a facing the second side wall 20b, and the planar size of the convex block 201 is larger than the planar size of the key cap 110. A groove 202 that is concavo-convexly fitted with the convex block 201 is formed on the inner side surface of the second side wall 20b facing the first side wall 20a. The bottom wall of the groove 202 is placed on the convex surface of the convex block 201, and the side wall of the groove 202 surrounds the outer periphery of the convex block 201, so as to form a concavo-convex limiting fit relationship with the convex block 201. A waterproof layer 240 is formed between the second side wall 20b and the first side wall 20a, and the waterproof layer 240 is disposed around the outer periphery of the side key 100. The waterproof layer 240 can be configured as a waterproof glue disposed around the convex block 201 for one week on the outer side surface of the first side wall 20a, and is used to block external water vapor from entering the interior of the electronic device through the gap between the second side wall 20b and the first side wall 20a, which can further improve the waterproof effect of the waterproof assembly structure A1.
