[0049] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0050] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the present disclosure belongs.

[0051] Nowadays, in portable terminal devices, the side key assembly has the advantages of being more convenient and quick to operate. Users can press the side key to control the terminal device while picking up a mobile phone or tablet, without having to operate or adjust the finger position again, and without occupying the space on the back of the mobile phone or the screen. Taking the side fingerprint assembly as an example, the side key fingerprint assembly refers to a fingerprint recognition module assembled on the side wall of the middle frame of a portable terminal device such as a mobile phone or a tablet. The user can complete the fingerprint recognition function by pressing the side key to unlock the portable terminal device. In implementation, the user can complete the fingerprint unlocking while picking up the mobile phone or tablet, without having to operate or adjust the finger position again, and the unlocking convenience is greatly improved. At present, the side key assembly work of the portable terminal device is usually completed manually by technicians. However, there are deviations in the direction and magnitude of the force applied to the side key by different technicians, which inevitably leads to the side key being skewed or not assembled in place after assembly, resulting in poor assembly consistency of the portable terminal. In view of this problem, the embodiment of the present disclosure provides a side key assembly device for a portable terminal. The side key is assembled using the assembly device, which can improve the assembly consistency of the portable terminal and improve the assembly efficiency.

[0052] Figure 1 is a schematic diagram of the structure of a side key assembly device of a portable terminal provided by an embodiment of the present disclosure, such as Figure 1 As shown, the side key assembly device of the portable terminal includes a fixing plate 1 , a driving assembly 2 and a pushing block 3 .

[0053] Among them, the fixed plate 1 has a first accommodating groove 11 and a second accommodating groove 12 that are connected to each other. The first accommodating groove 11 is used to accommodate the portable terminal. The driving component 2 is connected to the fixed plate 1. The push block 3 is at least partially located in the second accommodating groove 12 and is connected to the driving component 2. The driving component 2 is used to drive the push block 3 to move toward or away from the first accommodating groove 11.

[0054] In this way, the portable terminal can be placed in the first receiving groove 11 for limiting, and the technician can place the side key in the corresponding mounting hole on the middle frame, and then drive the push block 3 to push the side key through the driving component 2, drive the side key to move into the mounting hole, and complete the side key assembly. During the assembly process, by controlling the movement stroke and movement direction of the driving component 2, it is possible to avoid the side keys being skewed or not fully assembled after assembly, thereby improving the assembly consistency of the portable terminal. At the same time, due to the limiting and fixing function of the fixing plate 1, when assembling the latch corresponding to the side key, the technician no longer needs to use both hands to fix the terminal device, which also improves the convenience and efficiency of assembly.

[0055] The following describes the various parts of the side key assembly device of the portable terminal:

[0056] 1. Fixed plate 1

[0057] The fixing plate 1 is a component used for fixing and limiting the position of the portable terminal in the side key assembly device of the portable terminal. Figure 1 As shown, the fixing plate 1 has a first receiving groove 11, and the first receiving groove 11 is used to receive the portable terminal.

[0058] In some possible embodiments, the fixing plate 1 has a plate-like structure, and a first accommodating groove 11 is provided on the wall surface of the fixing plate 1. The shape of the first accommodating groove 11 matches the shape and size of the portable terminal. That is, when the shape of the portable terminal device is rectangular, the shape of the first accommodating groove 11 is rectangular.

[0059] In one example, if Figure 5 As shown, the wall surface of the fixing plate 1 is provided with a plurality of limiting protrusions 14, and the plurality of limiting protrusions 14 are arranged to surround and form the first receiving groove 11. The limiting protrusions 14 and the fixing plate 1 can be integrally formed parts, or can be parts processed in steps. In the case where the limiting protrusions 14 and the fixing plate 1 are parts processed in steps, the connection between the limiting protrusions 14 and the fixing plate 1 can be bonding. The fixing plate 1 with a plurality of limiting protrusions 14 can be processed and formed by a casting process, or can be processed and formed by a processing injection molding process, and the embodiments of the present disclosure do not limit this.

[0060] like Figure 5As shown, the fixing plate 1 has a rectangular plate structure, the limiting protrusion 14 can have a cubic structure, and the multiple limiting protrusions 14 are all located on the wall surface of the fixing plate 1 away from the mounting platform assembly 5, and are correspondingly distributed on the edges of the fixing plate 1. A mounting hole 112 is provided in the middle of the fixing plate 1, and the limiting protrusions 14 located on the same edge are flush with each other near the wall surface of the mounting hole 112, and the multiple limiting protrusions 14 are surrounded to form a first receiving groove 11, and the shape of the first receiving groove 11 is rectangular.

[0061] Exemplarily, the size of the first receiving slot 11 matches the size of a portable terminal device (such as a tablet computer).

[0062] In practice, the portable terminal device is placed in the first receiving groove 11 , and the side wall of the middle frame of the portable terminal device is attached to the side wall of the first receiving groove 11 , so that the first receiving groove 11 limits the position of the portable terminal device.

[0063] like Figure 1 As shown, the fixing plate 1 further has a second accommodating groove 12 , which is connected to the first accommodating groove 11 , and is used to accommodate the pushing block 3 .

[0064] In one example, the first receiving groove 11 and the second receiving groove 12 are formed by a cutting process. The size of the second receiving groove 12 is larger than the size of the orthographic projection of the push block 3 on the fixing plate 1 .

[0065] In this way, the difficulty of forming the first receiving groove 11 and the second receiving groove 12 can be reduced, and at the same time, the push block 3 can be prevented from being scratched against the side wall of the second receiving groove 12 during movement.

[0066] In some possible embodiments, the assembly system further includes a limit block 4, such as Figure 5 As shown, a mounting hole 112 is provided at the middle position of the bottom of the first accommodating groove 11 , and the mounting hole 112 is used for detachably connecting with the limiting block 4 in the assembly equipment.

[0067] In practice, when the stopper 4 is not connected to the mounting hole 112, the size of the portion of the first receiving slot 11 communicating with the second receiving slot 12 is a first size, which matches the size of a larger portable terminal device such as a tablet computer, and when the stopper 4 is connected to the mounting hole 112, the size of the portion of the first receiving slot 11 communicating with the second receiving slot 12 is a second size, which matches the size of a smaller portable terminal device such as a smart phone. In this way, by assembling the stopper 4 and the mounting hole 112, the size of the portion of the first receiving slot 11 communicating with the second receiving slot 12 can be adjusted, thereby expanding the applicable range of the assembled device.

[0068] In one example, the limit block 4 is detachably connected to the mounting hole 112 through interference fit, and the side of the limit block 4 close to the fixing plate 1 has a pin structure that matches the mounting hole 112, and the pin structure is interference fit with the mounting hole 112. The shape of the above-mentioned mounting hole 112 can be circular or rectangular, which is not limited in the embodiments of the present disclosure.

[0069] In one example, the limit block 4 is detachably connected to the mounting hole 112 through threaded cooperation, and the side of the limit block 4 close to the fixed plate 1 has a pin structure that cooperates with the mounting hole 112, the outer wall of the pin structure has an external thread, and the inner wall of the mounting hole 112 has a matching internal thread.

[0070] In this way, the connection convenience between the limiting block 4 and the mounting hole 112 can be improved.

[0071] Optionally, there may be a plurality of mounting holes 112 , and the plurality of mounting holes 112 are spaced apart and distributed in a third direction, and the third direction is parallel to an extending direction of the second receiving groove 12 .

[0072] In this way, after the limit block 4 is connected to different mounting holes 112, the size of the portion connecting the first accommodating groove 11 and the second accommodating groove 12 is different. The portion connecting the first accommodating groove 11 and the second accommodating groove 12 can be used to limit portable terminal devices of different sizes, thereby improving the applicability of the fixing plate 1.

[0073] In some possible embodiments, Figure 4 As shown, the bottom of the first receiving groove 11 has a clearance area 111, and the clearance area 111 is used to be engaged with the protruding structure on the back panel of the portable terminal.

[0074] In practice, a portable terminal device such as a tablet computer, a smart phone, etc. may have a back panel with a raised structure for accommodating a camera module. By providing an air avoidance area 111 to accommodate the raised structure, the back panel of the portable terminal device can be fitted with the bottom of the first accommodating groove 11, thereby improving the limiting stability of the portable terminal device in the first accommodating groove 11.

[0075] 2. Drive Components 2

[0076] The driving assembly 2 is a component in the side key assembly device of the portable terminal for driving the push block 3 to move.

[0077] like Figure 1 As shown, the driving assembly 2 is connected to the fixing plate 1 , and the driving assembly 2 is used to drive the pushing block 3 to move toward or away from the first receiving groove 11 .

[0078] In some possible embodiments, the driving assembly 2 is a pneumatic component.

[0079] like Figure 3 As shown, the driving assembly 2 includes a driving cylinder 21 and a connecting rod 22. The driving cylinder 21 is connected to the fixed plate 1. One end of the connecting rod 22 is connected to the telescopic rod 211 of the driving cylinder 21. The telescopic rod 211 is configured to move in a direction close to or away from the first receiving groove 11. A piston cavity (not shown) is provided inside the driving cylinder 21. The telescopic rod 211 is located inside the piston cavity and is slidably connected to the piston cavity. One end of the telescopic rod 211 located inside the piston cavity has a baffle structure (not shown). The baffle structure divides the piston cavity into a first cavity and a second cavity. The driving cylinder 21 has a first air inlet and a second air inlet (both not shown), wherein the first air inlet is connected to the first cavity, and the second air inlet is connected to the second cavity. In implementation, when the first air inlet is in a high-pressure state and the second air inlet is in a normal-pressure state, the pressure in the first cavity is greater than the pressure in the second cavity, and the telescopic rod 211 moves toward the direction approaching the first containing groove 11. Correspondingly, when the first air inlet is in a normal-pressure state and the second air inlet is in a high-pressure state, the pressure in the first cavity is less than the pressure in the second cavity, and the telescopic rod 211 moves away from the first containing groove 11.

[0080] In an example, the side key assembly device of the portable terminal further includes a control switch 100 and a controller 200 , and the fixing plate 1 has a control switch mounting groove 13 .

[0081] like Figure 4 As shown, the control switch 100 is disposed in the control switch mounting slot 13 and is electrically connected to the controller 200. The controller 200 is electrically connected to the driving cylinder 21.

[0082] The control switch 100 is used to control the controller 200 to switch between a first state and a second state, and the controller 200 is used to control the telescopic rod 211 to move toward the first receiving groove 11 in the first state, and to control the telescopic rod 211 to move away from the first receiving groove 11 in the second state.

[0083] Exemplarily, a first solenoid valve can be arranged between the first air inlet and the corresponding air inlet pipe, and a second solenoid valve can be arranged between the second air inlet and the corresponding air inlet pipe (neither of which is shown in the figure). The controller 200 can be electrically connected to the first solenoid valve and the second solenoid valve. The controller 200 is used to control the first solenoid valve to be in an open state and the second solenoid valve to be in a closed state in a first state, and to control the first solenoid valve to be in a closed state and the second solenoid valve to be in an open state in a second state.

[0084] In this way, when the technician is assembling the side key, he only needs to press the control switch 100 to control the movement of the push block 3 through the driving component 2, thereby improving the assembly efficiency.

[0085] In some possible embodiments, the driving assembly 2 is slidably connected to the fixing plate 1 .

[0086] like Figure 2 As shown, the fixing plate 1 has a plurality of second accommodating grooves 12, and the plurality of second accommodating grooves 12 are all connected to the first accommodating grooves 11, and the plurality of second accommodating grooves 12 are spaced apart and distributed along the first direction. Figure 3 The driving cylinder 21 is slidably connected to the fixing plate 1 in a first direction or a second direction, wherein the second direction is opposite to the first direction.

[0087] In this way, only one driving component 2 is required in the assembly device to realize the assembly of various side keys. For example, after completing the assembly of the fingerprint component, the driving component 2 slides along the first direction to continue to complete the assembly of the volume component, which can reduce the overall cost of the assembly device.

[0088] In one example, a slide rail structure is provided on the wall surface of the fixed plate 1 away from the first receiving groove 11, and the driving cylinder 21 is provided on the slider structure on the side close to the fixed plate 1, and the slider structure is slidably connected with the slide rail structure (both not shown). In this way, the connection convenience between the driving component 2 and the fixed plate 1 can be improved.

[0089] 3. Push Block 3

[0090] The push block 3 is a component in the side key assembly device of the portable terminal for contacting the side key to be assembled.

[0091] like Figure 1 As shown, the push block 3 is at least partially located in the second accommodating groove 12 and is connected to the driving assembly 2 .

[0092] In one example, the push block 3 is made of silicone material, and the push block 3 is connected to the connecting rod 22 in the driving assembly 2. The connection method between the push block 3 and the driving assembly 2 can be bonding or clamping, which is not limited in the embodiment of the present disclosure.

[0093] In one example, the hardness of the push block 3 is less than the hardness of the side key, the cross-sectional area of ​​the push block 3 in the axial direction perpendicular to the second accommodating groove 12 is a rectangle, and the length of the rectangle is greater than the length of the side key, and the width of the rectangle is greater than the length of the side key.

[0094] Exemplarily, the hardness of the push block 3 is 70HB, and the difference between the length of the rectangle and the length of the side key, and the difference between the width of the rectangle and the width of the side key are both 1 mm.

[0095] In this way, the push block 3 can completely cover the side key during the process of pushing the side key, avoiding the side key from tilting after assembly. At the same time, since the hardness of the push block 3 is less than that of the side key, scratches can be left on the surface of the side key.

[0096] Optionally, in some possible embodiments, the assembly equipment further includes a mounting table assembly 5 .

[0097] like Figure 3 As shown, the mounting platform assembly 5 includes a base 51 , a first connecting member 52 and a second connecting member 53 .

[0098] like Figure 3 As shown, the base 51 has a rectangular plate structure. The base 51 is located below the fixing plate 1 and is connected to the first connecting member 52 .

[0099] Exemplarily, the material of the base 51 can be various metal materials or alloy materials with high density, such as alloy steel, cast iron, etc., so that the base 51 can have a large mass to improve the stability of the mounting table assembly 5 set on the workbench. The embodiments of the present disclosure are not limited to this.

[0100] like Figure 3 As shown, the first connecting member 52 has a plate-like structure, the first connecting member 52 is perpendicular to the base 51, and one end is connected to the base 51. The connection between the first connecting member 52 and the base 51 can be welding or bonding, which is not limited in the embodiment of the present disclosure. The second connecting member 53 has a plate-like structure, one end of the second connecting member 53 is rotatably connected to the first connecting member 52, and the other end is fixedly connected to a side of the fixing plate 1 away from the first receiving groove 11.

[0101] In one example, if Figure 3 As shown, the first connecting member 52 has a first through hole 521 and a plurality of second through holes 522, the first through hole 521 is a circular through hole, the first through hole 521 is used to accommodate a rotating shaft (not shown), the second through holes 522 are circumferentially distributed around the first through hole 521, the second connecting member 53 is arranged parallel to the first connecting member 52, and is rotatably connected to the above-mentioned rotating shaft, a through groove structure 531 is arranged on the second connecting member 53, the through groove structure 531 is an arc-shaped through groove, the radius of the through groove structure 531 is equal to the distance between the first through hole 521 and the second through hole 522, and the circle of the through groove structure 531 coincides with the axis of the first through hole 521.

[0102] In practice, the fixing assembly includes a fixing bolt and a nut (neither of which is shown), the fixing bolt passes through the second through hole 522 and the through slot structure 531 in sequence, and is threadedly connected to the nut, the outer diameter of the nut is larger than the slot width of the through slot structure 531, the bolt head of the fixing bolt is located on the side of the first connecting member 52 away from the second connecting member 53, and is in contact with the first connecting member 52, the nut is located on the side of the second connecting member 53 away from the first connecting member 52, and is in contact with the second connecting member 53, the bolt head and the nut are used to support and fix the first connecting member 52 and the second connecting member 53.

[0103] In this way, the inclination angle of the fixing plate 1 relative to the workbench is adjustable, which can improve the convenience of operation for technicians during the assembly process of the side keys.

[0104] In one example, the angle between the fixing plate 1 and the base 51 is within a first preset range, and the first preset range is [30°, 40°].

[0105] For example, the angle between the fixing plate 1 and the base 51 is 35°. It has been verified through experience that when the angle between the fixing plate 1 and the base 51 is 35°, it is more convenient for technicians to assemble the side keys. Therefore, this angle can be used to complete the assembly of the side keys, thereby improving assembly efficiency.

[0106] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0107] The embodiment of the present disclosure provides a side key assembly device for a portable terminal, in which a fixed plate 1 has a first receiving groove 11 and a second receiving groove 12 connected to each other, the first receiving groove 11 is used to accommodate the portable terminal, the driving component 2 is connected to the fixed plate 1, the push block 3 is at least partially located in the second receiving groove 12, and is connected to the driving component 2, and the driving component 2 is used to: drive the push block 3 to move in a direction close to or away from the first receiving groove 11. In this way, the portable terminal can be placed in the first receiving groove 11 for limiting, and the technician can place the side key in the corresponding mounting hole on the middle frame, and then, the driving component 2 drives the push block 3 to push the side key, drive the side key to move inside the mounting hole, and complete the side key assembly. During the assembly process, by controlling the movement stroke and movement direction of the driving component 2, it is possible to avoid the side key being skewed or not assembled in place after assembly, thereby improving the assembly consistency of the portable terminal. At the same time, due to the limiting and fixing function of the fixed plate 1, when assembling the latch corresponding to the side key, the technician no longer needs to use both hands to fix the terminal device, which also improves the assembly convenience and assembly efficiency. After experimental verification, using the above-mentioned assembly equipment to complete the assembly work can save about 5-10 seconds of side key assembly time for each portable terminal device on average, and can save about 0.05 yuan of side key assembly cost for each portable terminal device on average.
