Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and in particular to a touch module and an electronic device. Background Art

[0002] Touch modules are installed in electronic devices such as mobile phones, tablets, and computers. To ensure the user's touch feel, the touch module is generally composed of a circuit board, an elastic member, and a base plate. The elastic member is generally between the circuit board and the base plate, and the two ends of the elastic member are respectively connected to the circuit board and the base plate. At present, the connection between the elastic member and the circuit board and the base plate is generally carried out by snapping, locking or welding. However, due to the small size of the elastic member and the limited working space of the circuit board and the base plate, the above installation method is difficult, which makes the production cost of the touch module high. Utility Model Content

[0003] In view of the above, it is necessary to provide a touch module and an electronic device so that the touch module can achieve low production cost while satisfying the pressing feel.

[0004] The embodiment of the utility model provides a touch module, which is used to be installed on one side of a substrate to form a touch panel, and the touch module includes:

[0005] A circuit board connected to one side of the substrate;

[0006] A pressure-sensitive element is disposed on a side of the circuit board away from the substrate;

[0007] A support member is provided on a side of the circuit board away from the substrate and includes a mounting body and an elastic body, wherein the mounting body covers the pressure-sensitive element and is spaced apart from the pressure-sensitive element, the mounting body is provided with a mounting hole, the mounting hole penetrates the mounting body and is located on the periphery of the pressure-sensitive element, one end of the elastic body is connected to the mounting body, and the other end of the elastic body is abutted against the circuit board, and the elastic body is used to provide elastic support between the circuit board and the mounting body;

[0008] An adhesive member is disposed between the circuit board and the other end of the elastic body, and the adhesive member is connected to the circuit board and the other end of the elastic body respectively;

[0009] A limiter, comprising a fixed body, a guide body and a stopper, wherein the fixed body is connected to the circuit board, the guide body is movably arranged in the direction from the mounting body to the circuit board, and one end of the guide body is detachably connected to the fixed body, and the other end of the guide body is connected to the stopper, and the stopper is located on the side of the mounting body away from the circuit board and is used to stop the mounting body; wherein,

[0010] The substrate drives the circuit board to move in a direction close to the mounting body under pressure, so that the circuit board presses the pressure-sensitive element to the mounting body, and the elastic body is pushed by the circuit board to be received in the mounting hole.

[0011] When assembling the above touch module, first install the pressure-sensitive element and the fixed body on the circuit board respectively, and connect the adhesive to the predetermined position of the circuit board. Then, drive the support to move and observe through the mounting hole. When the other end of the elastic body in the support corresponds to the adhesive, press the mounting body until the other end of the elastic body is connected to the adhesive. At this time, the through hole on the mounting body for inserting the guide body corresponds to the fixed body on the circuit board. Finally, drive the guide body through the through hole to connect with the fixed body, and make the stopper form a stopper for the mounting body in the direction from the mounting body to the circuit board. Therefore, the adhesive and mounting hole in the above touch module can guide the support to align with the circuit board, and realize the connection between the circuit board and the support by bonding the adhesive and locking the limiter. The assembly difficulty is low, which reduces the production cost of the touch module. In addition, the elastic body can provide elastic support between the circuit board and the mounting body to meet the user's pressing feel of the touch module.

[0012] In some embodiments, the elastomer comprises:

[0013] An elastic portion is arranged obliquely relative to the mounting body, one end of the elastic portion is connected to the side wall of the mounting hole, and the other end of the elastic portion is extended from the mounting body toward the circuit board;

[0014] The pressing portion presses against the circuit board, and the pressing portion is connected to the other end of the elastic portion.

[0015] Therefore, the elastic portion, the pressing portion and the mounting body are arranged to form a hollow area, which can avoid the components on the circuit board and is conducive to promoting the lightweight and thin setting of the touch module.

[0016] In some embodiments, there are at least two mounting holes, at least two elastomers, and at least two adhesives, and at least two mounting holes, at least two elastomers, and at least two adhesives correspond to each other one by one, and at least two mounting holes are arranged around the pressure-sensitive element.

[0017] Therefore, through the above configuration, when any position of the substrate is subjected to a force, the pressure-sensitive element can sense the force through the circuit board, so that the touch module can achieve full-area pressing, which is beneficial to improving the user's touch experience of the touch panel where the touch module is located.

[0019] Therefore, through the above arrangement, the elastic force of the elastic body applied to the circuit board is uniform, which is beneficial to improving the uniformity of the pressure applied to the pressure-sensitive element.

[0020] In some embodiments, one end of the elastic body is connected to the side wall of the mounting hole, and the mounting body and the elastic body are an integral structure.

[0021] Therefore, the integrated structure of the mounting body and the elastic body can simplify the processing technology of the support member, thereby reducing the production cost of the support member.

[0022] In some embodiments, the stopper further comprises:

[0023] A gasket is sleeved on the guide body and located between the mounting body and the stopper body.

[0024] Therefore, the gasket can reduce the wear of the stopper on the mounting body, which is beneficial to improving the service life of the support. In some embodiments, the fixing body is a nut, and the fixing body is embedded in the side of the circuit board away from the substrate, the guide body and the stopper are integrally formed to form a bolt, the guide body is the screw of the bolt, and the stopper is the head of the bolt.

[0025] Therefore, the locking structure of the nut and the bolt is simple to install and has low cost.

[0026] In some embodiments, there are multiple limiting members, and the multiple limiting members are symmetrically arranged relative to the center of the circuit board.

[0027] Therefore, the symmetrically arranged multiple limit members can connect the installation body and the circuit board at multiple points, which is beneficial to improving the stability of the connection between the circuit board and the support member.

[0028] In some embodiments, the touch module further includes:

[0029] The electronic component is mounted on the circuit board and received in the mounting hole.

[0030] Therefore, the electronic components are housed in the mounting holes, which is beneficial to promoting the lightweight and thin configuration of the touch module.

[0031] The present invention also provides an electronic device, including:

[0032] The touch module described in the above embodiment;

[0033] A substrate, arranged on a side of the circuit board away from the support member;

[0034] The housing accommodates the touch module and is connected to the substrate.

[0035] When assembling the above-mentioned electronic device, first install the pressure-sensitive element to the circuit board and connect the adhesive to the predetermined position of the circuit board.

When the other end of the elastic body in the support corresponds to the adhesive, press the mounting body until the other end of the elastic body is connected to the adhesive. At this time, the mounting body and the circuit board are aligned. Then, install the limiter to fix the circuit board and the support.

[0066] The following is a detailed description of various embodiments of the present invention in conjunction with the accompanying drawings.

[0067] See also Figure 1 and Figure 2The embodiment of the utility model provides a touch module 100, which is used to be installed on one side of a substrate to form a touch panel. The touch module 100 includes a circuit board 110, a pressure-sensitive element 120, a support member 130, an adhesive member 140 and a stop member 150. The circuit board 110 is connected to one side of the substrate, and the pressure-sensitive element 120 is arranged on the side of the circuit board 110 away from the substrate. The support member 130 is arranged on the side of the circuit board 110 away from the substrate and includes a mounting body 131 and an elastic body 132. The mounting body 131 covers the pressure-sensitive element 120 and is spaced from the pressure-sensitive element 120. The mounting body 131 is provided with a mounting hole 131a, which passes through the mounting body 131 and is located on the peripheral side of the pressure-sensitive element 120. One end of the elastic body 132 is connected to the mounting body 131, and the other end of the elastic body 132 is abutted against the circuit board 110. The elastic body 132 is used to provide elastic support between the circuit board 110 and the mounting body 131. The adhesive member 140 is disposed between the circuit board 110 and the other end of the elastic body 132, and the adhesive member 140 is connected to the circuit board 110 and the other end of the elastic body 132 respectively. The limiter 150 includes a fixed body 151, a guide body 152 and a stopper 153. The fixed body 151 is connected to the circuit board 110, and the guide body 152 is movably arranged in the mounting body 131 from the mounting body 131 to the circuit board 110. One end of the guide body 152 is detachably connected to the fixed body 151, and the other end of the guide body 152 is connected to the stopper 153. The stopper 153 is located on the side of the mounting body 131 away from the circuit board 110 and is used to stop the mounting body 131. In this embodiment, the adhesive member 140 is cured glue. In other embodiments, the adhesive member 140 can also be a double-sided tape.

[0068] The substrate drives the circuit board 110 to move toward the mounting body 131 under pressure, so that the circuit board 110 presses the pressure-sensitive element 120 to the mounting body 131 and the elastic body 132 is pushed by the circuit board 110 to be received in the mounting hole 131a.

[0069] It should be noted that the mounting hole 131a being located on the peripheral side of the pressure-sensitive element 120 means that the mounting hole 131a and the pressure-sensitive element 120 are staggered in the extension direction of the mounting hole 131a. One mounting hole 131a or two or more mounting holes 131a can be set on the peripheral side of the pressure-sensitive element 120.

Then, the support member 130 is driven to move and observed through the mounting hole 131a. When the other end of the elastic body 132 in the support member 130 corresponds to the adhesive 140, the mounting body 131 is pressed until the other end of the elastic body 132 is connected to the adhesive 140. At this time, the through hole 131b on the mounting body 131 for inserting the guide body 152 corresponds to the fixed body 151 on the circuit board 110. Finally, the guide body 152 is driven to pass through the through hole 131b to be connected to the fixed body 151, and the stopper 153 forms a stopper for the mounting body 131 in the direction from the mounting body 131 to the circuit board 110. Therefore, the adhesive member 140 and the mounting hole 131a in the touch module 100 can guide the support member 130 to align with the circuit board 110, and the connection between the circuit board 110 and the support member 130 is achieved through the bonding of the adhesive member 140 and the locking of the stopper 150, which reduces the assembly difficulty and reduces the production cost of the touch module 100. In addition, the elastic body 132 can provide elastic support between the circuit board 110 and the mounting body 131 to meet the user's pressing feel of the touch module 100.

[0071] See also Figure 1 and Figure 2 In some embodiments, the elastic body 132 includes a pressing portion 1321 and an elastic portion 1322.

[0080] In other embodiments, the pressure-sensitive element 120 may also be arranged only at the end of the circuit board 110, or both at the central area and at the end of the circuit board 110. The number of pressure-sensitive elements 120 may be specifically arranged based on the structure of the mounting body 131 and the circuit board 110.

[0081] In some embodiments, one end of the elastic body 132 is connected to the side wall of the mounting hole 131 a , and the mounting body 131 and the elastic body 132 are an integral structure.

[0082] Therefore, the integrated structure of the mounting body 131 and the elastic body 132 can simplify the processing technology of the support member 130 , thereby reducing the production cost of the support member 130 .

[0084] Therefore, the gasket 154 can reduce the wear of the stopper 153 on the mounting body 131 , which is beneficial to improving the service life of the support member 130 .

[0085] See also Figure 1 and Figure 2 In some embodiments, the fixing body 151 is a nut, and the fixing body 151 is embedded in the side of the circuit board 110 away from the substrate, the guide body 152 and the stop body 153 are integrally formed and form a bolt, the guide body 152 is the screw rod of the bolt, and the stop body 153 is the head of the bolt.

[0086] Therefore, the locking structure of the nut and the bolt is simple to install and has low cost.

[0088] In this embodiment, the circuit board 110 and the mounting body 131 are both roughly rectangular parallelepiped, and there are four stoppers 150, which are respectively arranged at the four end corners of the mounting body 131. In other embodiments, there may be three, five or more stoppers 150.

[0089] Therefore, the symmetrically arranged plurality of stoppers 150 can connect the mounting body 131 and the circuit board 110 at a plurality of points, which is beneficial to improving the stability of the connection between the circuit board 110 and the support member 130 .

[0090] In some embodiments, the touch module 100 further includes an electronic component 160. The electronic component 160 is mounted on the circuit board 110 and received in the mounting hole 131a.
