DETAILED DESCRIPTION

[0042] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0043] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the touch panel assembly structure provided by the embodiment of the present disclosure includes a cover body 1, a touch component 2 and a transmission member 3; the cover body 1 is provided with an abutment portion 14; the touch component 2 is used to receive a user's touch operation, and the touch component 2 includes a touch switch 23, and the touch switch 23 is arranged corresponding to the abutment portion 14.

[0044] In some specific embodiments, the touch assembly 2 further includes a touch panel and a circuit board 22. The touch panel 21 and the circuit board 22 are stacked, that is, the touch panel is arranged above the circuit board 22, and the touch switch 23 is arranged below the circuit board 22. The touch panel is used to receive a touch operation of the user. The circuit board 22 can be a PCB board or a PCBA board.

[0045] Optionally, when the touch panel is not pressed, there is a gap between the touch switch 23 and the abutment portion 14, and after the touch panel 21 is pressed, the touch switch 23 presses against the abutment portion 14, so that the touch panel generates a touch signal. Specifically, when the touch panel is not pressed, no touch signal is generated; after the touch panel is pressed, the abutment portion 14 cooperates with the touch switch 23 to generate a touch signal.

[0046] Optionally, a metal spring is provided in the touch switch 23. When the touch switch 23 is not pressed, the metal spring is in a natural state and does not contact the circuit board 22. After the contact portion 14 and the touch switch 23 are pressed against each other, the metal spring is elastically deformed and touches the circuit board 22, and a current path is generated between the metal spring and the circuit board 22, triggering a touch signal.

[0047] The transmission member 3 has a first end and a second end, the first end is connected to the touch assembly 2, and the second end is limited to the cover body 1, so that there is a movable gap between the first end and the cover body 1, which is used to drive the touch assembly 2 to rise and fall along the height direction Z of the cover body 1, so that when the touch assembly 2 descends under the action of an external force, the touch switch 23 abuts against the abutment portion 14. Through the transmission member 3, when the touch assembly 2 makes a descending movement, the touch switch abuts against the abutment portion 14, thereby triggering the touch switch. That is, there is a movable gap between the first end and the cover body 1, so that the first end can move in a direction close to or away from the cover body 1, so that after the first end moves in a direction close to the upper cover, the touch switch can abut against the abutment portion 14.

[0048] Optionally, the first end is plate-shaped and extends along the length direction X of the cover 1. The first end can be arranged close to the front side of the touch component 2 so that when the operator presses the front side of the touch component 2, the touch component 2 can keep synchronous movement through the transmission member 3.

[0049] The touch switch can be welded on the circuit board 22, or the touch switch can be fixed on the circuit board 22 by means of a clamp or fastener. The touch switch can be fixed in the central area of ​​the circuit board 22 or in the edge area. In the embodiment of the present disclosure, the touch switch can be arranged in the area near the front side of the circuit board 22.

[0050] The abutting portion 14 may be a protruding structure formed on the cover body 1 and protruding toward the touch switch for contacting the touch switch. The protruding height of the protruding structure may be set according to actual needs.

[0051] Combination Figure 3 and Figure 7 As shown, in the embodiment of the present disclosure, the first area of ​​the touch component 2 is connected to the transmission member 3 through the first structural adhesive 4, the second area of ​​the touch component 2 is connected to the cover body 1 through the second structural adhesive 5, and the second structural adhesive 5 and the transmission member 3 are arranged at intervals along the width direction Y of the cover body 1. Compared with the existing method of fixing the touch component 2 and the cover body 1 with screws, in the embodiment of the present disclosure, the touch component 2 and the transmission member 3 are connected through the first structural adhesive 4, and the touch component 2 and the cover body 1 are connected through the second structural adhesive 5, which reduces the number of parts, simplifies the assembly method, and can improve the assembly efficiency.

[0052] Optionally, the first area and the second area are spaced apart, the first area is an area close to the front side, and the second area is an area close to the rear side.

[0053] The touch panel assembly structure provided in the embodiment of the present disclosure adopts only one transmission member 3, which reduces the number of parts on the one hand, and can reduce the overall thickness of the touch panel assembly structure on the other hand, so that the electronic device using the touch panel assembly structure can be thinner as a whole, facilitating the realization of an extremely ultra-thin structure.

[0054] The touch panel assembly structure provided by the embodiment of the present disclosure replaces the traditional screw locking, which can save the height occupied by the screws and make the overall thickness smaller.

[0055] It should be noted that, during the lifting and lowering movement of the touch component 2, the first area of ​​the touch component 2 moves upward under the action of the transmission member 3. Since the second area of ​​the touch component 2 close to the rear side is connected to the cover body 1 through the second structural adhesive 5, the first area will be slightly tilted when the touch component 2 moves up and down.

[0056] In addition, the first structural adhesive 4 can be an adhesive, specifically a double-sided adhesive, as long as it can bond the transmission member 3 to the circuit board 22. The second structural adhesive 5 can be an easy-to-pull adhesive, which has the advantage of being easy to disassemble. Preferably, the thickness of the easy-to-pull adhesive is 0.2 mm, which can improve the stability of the connection between the touch component 2 and the cover body 1 and reduce the thickness of the entire device.

[0057] In some specific implementations, a CCD positioner is attached to the circuit board 22 .

[0058] Combination Figure 3 , Figure 5 and Figure 6 As shown, the touch assembly 2 includes a touch panel and a circuit board 22, the touch panel is arranged above the circuit board 22, the touch switch 23 is arranged below the circuit board 22, and the tops of the first structural adhesive 4 and the second structural adhesive 5 are both connected to the circuit board 22; the number of parts is reduced, the assembly method is simple, and the assembly efficiency can be improved

[0059] Combination Figure 6 , Fig. 9 , Fig.10 and Fig.12 As shown, the transmission member 3 includes a bracket 31, and an extension portion 32 is formed on one side of the bracket 31, the first end of which is located at the bracket 31, and the second end of which is located at the extension portion 32; along the height direction Z, the extension portion 32 extends downward from the bracket 31, and the extension portion 32 is provided with a first limiting hole 321; the top surface of the cover body 1 is formed with a first recessed portion 11, and the first recessed portion 11 includes a bottom plate 111, and a first limiting member 111a is provided on the side of the bottom plate 111, and the first limiting member 111a extends along the width direction Y of the cover body 1 toward the direction of the second area close to the touch component 2, and the first limiting member 111a is slidably matched with the first limiting hole 321. The first limiting hole 321 extends along the height direction Z to provide a movable stroke for the first limiting member 111a. The first stopper 111a can be rod-shaped or block-shaped, as long as the first stopper 111a can move in the first stopper hole 321 along the height direction Z after being plugged into the first stopper hole 321, so that the bracket 31 moves toward or away from the cover body 1. After the touch panel 21 is pressed, the touch panel 21 and the circuit board 22 press the bracket 31 downward, so that the touch switch 23 presses against the abutment portion 14, so that the touch panel generates a touch signal. When the touch panel is not pressed, the bracket 31 drives the circuit board 22 and the touch panel 21 to move upward, so that the touch switch 23 is separated from the abutment portion 14, and the touch panel 21 does not generate a touch signal.

[0060] Optionally, the bracket 31 is plate-shaped and extends along the length direction X of the cover 1 . The bracket 31 can be disposed near the front side of the touch component 2 so that when the operator presses the first area of ​​the touch component 2 , the touch component 2 can keep moving synchronously through the bracket 31 .

[0061] The first limiting member 111a and the first limiting hole 321 are slidably matched, which can prevent the possibility of the bracket 31 moving left and right and improve the stability of the touch panel 21. On the other hand, a limiting structure is formed to effectively avoid the problem of empty travel caused by large deformation of the touch component 2.

[0062] Combination Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.12 As shown, the first recessed portion 11 includes a side plate 112, which is connected to the bottom plate 111 and is provided with a second limiting hole 112a; the bracket 31 is provided with a second limiting member 33, which extends along the width direction Y of the cover body 1 in the direction away from the second area of ​​the touch component 2, and the second limiting member 33 and the second limiting hole 112a are slidably matched, which can prevent and reduce the possibility of the bracket 31 moving left and right, improve the stability of the touch panel 21, and on the other hand, limit the bracket 31, play a stopper role, and ensure that the touch component 2 can be normally triggered by pressing on both sides. The second limiting member 33 can be rod-shaped or block-shaped.

[0063] In some specific embodiments, an elastic member is provided between the transmission member 3 and the cover body 1 to reset the touch component 2 when the external force is removed. The elastic member can move the touch component 2 upward to reset, that is, the touch component 2 can rebound to the initial position, so that the touch component 2 can be easily pressed next time.

[0064] like Figure 7 As shown, the elastic member includes an elastic arm 111b, one end of the elastic arm 111b is connected to the base plate 111, and the other end is in contact with the bracket 31. In this way, after the external force is removed, the bracket 31 and the touch component 2 connected to the bracket 31 can return to their initial positions through the rebound force of the elastic arm 111b, making it easier for the touch component 2 to be pressed next time.

[0065] Optionally, there are two elastic arms 111b, which are respectively arranged on both sides of the abutting portion 14, so as to prevent the touch component 2 from collapsing, assist the touch component 2 in resetting, and improve the resetting stability of the touch component 2.

[0066] like Fig.12 As shown, the abutting portion 14 includes a protruding structure, which is arranged on the bottom plate 111, and the bracket 31 is provided with an avoidance hole 311. The protruding structure is penetrated through the avoidance hole 311, and is used to abut against the touch switch 23. When the touch panel is not pressed, there is a gap between the touch switch 23 and the protruding structure. After the touch panel 21 is pressed, the touch switch 23 presses the protruding structure, so that the touch panel generates a touch signal. When the touch panel is not pressed, there is a gap between the touch switch 23 and the protruding structure, and no touch signal is generated.

[0067] like Figure 7As shown, the top surface of the cover body 1 is provided with a second recessed portion 12, and the depth of the first recessed portion 11 is greater than the depth of the second recessed portion 12; the second structural adhesive 5 is arranged in the second recessed portion 12, part of the touch component 2 is arranged in the first recessed portion 11, and part of the touch component 2 is arranged in the second recessed portion 12, so that the bracket 31 can meet the Z-direction travel while further reducing the overall thickness of the touch panel assembly structure.

[0068] In some specific implementations, an escape opening 13 is provided between the first recessed portion 11 and the second recessed portion 12, so that the touch assembly 2 can meet the Z-direction travel and the touch panel assembly structure can be made thinner.

[0069] In some specific embodiments, the second recessed portion 12 is provided with a through hole 121, and at least part of the second structural adhesive 5 is provided in the through hole 121 for easy disassembly and maintenance. The through hole 121 can be a round hole or a square hole. Specifically, when the second structural adhesive 5 is an easy-to-pull adhesive, the handle of the easy-to-pull adhesive can be passed through the through hole 121 for easy disassembly and maintenance at a later stage. At the same time, the through hole 121 can be overlapped with the KB iron piece using a conductive cloth to meet EMC requirements.

[0070] In some specific embodiments, a battery 6 is installed on the bottom surface of the cover 1, and at least a portion of the cover 1 is disposed between the battery 6 and the touch component 2. The touch component 2 and the battery 6 are isolated by a portion of the cover 1. When the touch component 2 is pressed, the gap between the battery 6 and the cover 1 is not affected, so a 0gap design can be used between the battery 6 frame and the circuit board 22. Preferably, a 0.2mm gap can be left to absorb the slight interference problem caused by the deformation. Therefore, the thickness of the touch panel assembly structure can be further compressed to be extremely ultra-thin.

[0071] In some specific implementations, the cover body 1 is provided with an opening area 122 , and the opening area 122 can be sealed and reinforced with glue, which can improve the strength and deformation resistance and improve the pressing feel of the touch component 2 .

[0072] The electronic device provided in the embodiment of the present disclosure includes the touch panel assembly structure provided in the embodiment of the present disclosure. The electronic device may be one of smart devices such as a laptop computer, a smart phone, and a tablet computer, and the embodiment of the present disclosure does not specifically limit this. The electronic device provided in the embodiment of the present disclosure has the same advantages as the touch panel assembly structure provided in the embodiment of the present disclosure, which will not be described in detail here.

[0073] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.
