The main body includes a receiving cavity and a pressing portion located on one side of the receiving cavity; the bracket is disposed in the receiving cavity, and the bracket includes a connecting portion and a cantilever portion. The connecting portion is connected to the cantilever portion, and the connecting portion is connected to at least one inner wall of the receiving cavity; the cantilever portion is suspended in the receiving cavity through the connecting portion, and when the pressing portion is pressed, the cantilever portion deforms; a pressure sensing assembly is disposed on the cantilever portion for sensing the deformation of the cantilever portion. In the present application, the suspended cantilever portion is used as a supporting member of the pressure sensing assembly.

Description

[0001] This application belongs to the technical field of electronic devices, and particularly relates to a key module and an electronic device. Background Art

[0002] With the rapid development of intelligent devices, users have higher and higher requirements for the experience when using electronic devices. They often require virtual key modules to be set under the display screen of the electronic device to increase the controllability of the electronic device. In related technologies, the sensing layer in the pressure sensing component of the key module is prone to cracks after being pressed, which may lead to the failure of the key module. It can be seen that the reliability of the existing key modules is relatively low. Summary of the Invention

[0003] This application aims to provide a key module and an electronic device, and at least solve the problem of relatively low reliability of the key module.

[0004] To solve the above technical problems, this application is implemented as follows:

[0010] In the embodiment of this application, the cantilever portion of the bracket is suspended in the receiving cavity of the main body, and the pressure sensing component is disposed in the receiving cavity under the support of the cantilever portion. When the pressing portion of the main body is pressed, the cantilever portion can deform under the action of the pressing force, so that the pressure sensing component can sense the deformation of the cantilever portion. By using the suspended cantilever portion as the support component of the pressure sensing component, when the pressing portion is pressed, the cantilever portion deforms, and the stress is relatively dispersed. Therefore, when the pressure sensing component senses the deformation of the cantilever portion, the force is more uniform, which can effectively avoid the generation of cracks during the process of the sensing layer of the pressure sensing component being deformed by force.

Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0030] In the description of the present application, it should be noted that, unless otherwise clearly specified and defined, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] Please refer to Figure 1 , the pressure sensing component 3 may include a flexible circuit board 101, at least two pads 102, a sensing layer 103, a conductive portion 104 and an insulating layer 105. The at least two pads 102 are spaced apart on the flexible circuit board 101, and the sensing layer 103 is printed between the at least two pads 102. The conductive portion 104 is connected to the sensing layer 103 and the pads 102 for realizing electrical conduction between the sensing layer 103 and the pads 102. An insulating layer 105 having a protection and insulation function is printed on the surface of the sensing layer 103.

[0032] To increase the signal amount of the pressure sensing component 3, in related technologies, a separate steel reinforcement is usually used as the support component of the pressure sensing component 3. Exemplarily, the separate steel reinforcement is press-fitted on the side of the flexible circuit board away from the sensing layer 103 through a thermosetting adhesive, and the sensing layer 103 is located at the gap of the separate steel reinforcement. Then, the separate steel reinforcement and the pressure sensing component 3 are fixed on the surface of the display screen or the middle frame of the electronic device through an adhesive material. In this way, when the user presses the display screen of the electronic device, the sensing layer 103 can deform at the gap, thereby generating a pressure sensing signal.

[0033] However, the inventor found that due to the brittle characteristics of the pressure-sensing material of the sensing layer 103, during the stress process, the support strength of the gap area of the separate steel reinforcement is poor, and there are sharp corners at the gap edge. This area belongs to the stress concentration area. During the folding back of the flexible circuit board 101 or the press-fitting, testing, transportation, and assembly of the separate steel reinforcement, the sensing layer 103 in this area is prone to cracks, which may lead to the failure of the pressure sensing component 3 and the inability to achieve its normal function.

[0034] Based on the above technical problems, the embodiments of the present application provide a key module and an electronic device with relatively high reliability. First, the key module of the embodiments of the present application will be described below in conjunction with Figures 2 to 9 Describe the key module of the embodiments of the present application.

[0035] Please refer to Figure 2 , the embodiments of the present application provide a key module, which includes a main body 1, a bracket 2, and a pressure sensing component 3. The main body 1 may include a receiving cavity 11 and a pressing portion 12 located on one side of the receiving cavity 11; the bracket 2 is disposed in the receiving cavity 11, and the bracket 2 includes a cantilever portion 21 and a connecting portion 22. The connecting portion 22 is connected to the cantilever portion 21, and the connecting portion 22 is connected to at least one inner wall of the receiving cavity 11; the cantilever portion 21 is suspended in the receiving cavity 11 through the connecting portion 22, and when the pressing portion 12 is pressed, the cantilever portion 21 deforms; the pressure sensing component 3 is disposed on the cantilever portion 21 for sensing the deformation of the cantilever portion 21.

[0036] Among them, the material of the bracket 2 may be a deformable material such as metal or plastic. The structure of the pressure sensing component 3 may be as described above, including a flexible circuit board 101, at least two pads 102, a sensing layer 103, a conductive portion 104, and an insulating layer 105, which will not be elaborated here.

[0037] As Figure 2As shown, a receiving cavity 11 for installing the pressure sensing component 3 can be formed on the main body 1, and the pressure sensing component 3 can be installed in the receiving cavity 11 through the bracket 2. Exemplarily, the bracket 2 can include a cantilever portion 21 and a connecting portion 22. The cantilever portion 21 is connected to the connecting portion 22, and the connecting portion 22 is connected to at least one inner wall of the receiving cavity 11, so that the cantilever portion 21 is suspended in the receiving cavity 11. The pressure sensing component 3 is disposed on the cantilever portion 21 and can be used to sense the deformation of the cantilever portion 21.

[0038] As Figure 3 shown, the main body 1 can further include a pressing portion 12 located on one side of the receiving cavity 11. When the pressing portion 12 is pressed, the cantilever portion 21 can be deformed under the action of the pressing force, and further the pressure sensing component disposed on the cantilever portion 21 can sense the deformation of the cantilever portion 21. Exemplarily, the sensing layer 103 in the pressure sensing component 3 can generate a change in resistance based on the sensed deformation of the cantilever portion 21 and convert it into a pressure sensing signal, thereby realizing the function detection of the key module.

[0039] In the embodiment of the present application, the cantilever portion 21 of the bracket 2 is suspended in the receiving cavity 11 of the main body 1, and the pressure sensing component 3 is disposed in the receiving cavity 11 supported by the cantilever portion 21. When the pressing portion 12 of the main body 1 is pressed, the cantilever portion 21 can be deformed under the action of the pressing force, and further the pressure sensing component 3 can sense the deformation of the cantilever portion 21. By using the suspended cantilever portion 21 as the support component of the pressure sensing component 3, when the pressing portion 12 is pressed, the cantilever portion 21 deforms, and the stress is relatively dispersed. Thus, when the pressure sensing component 3 senses the deformation of the cantilever portion 21, the force is more uniform, which can effectively avoid the generation of cracks in the sensing layer 103 of the pressure sensing component 3 during the process of the force-induced deformation. At the same time, the suspended structure design makes the deformation sensed by the pressure sensing component 3 more obvious and the pressure sensing signal stronger. Therefore, the reliability of the key module is effectively improved.

[0040] Optionally, in some embodiments, the cantilever portion 21 can have a pressure-receiving surface that abuts against the pressing portion 12. When the pressing portion 12 is pressed, the pressure-receiving surface moves to deform the cantilever portion 21. Exemplarily, one end of the cantilever portion 21 can be connected to the inner wall of the receiving cavity 11 through the connecting portion 22, and the other end of the cantilever portion 21 can extend to form a pressure-receiving surface that abuts against the pressing portion 12. In this way, when the pressing portion 12 is pressed, the pressure-receiving surface moves under the drive of the pressing portion 12, causing the cantilever portion 21 to deform, so that the pressure sensing component 3 can sense the deformation of the cantilever portion 21 and realize the corresponding function of the key module.

[0041] Optionally, as Figure 2As shown, in some embodiments, one end of the cantilever portion 21 close to the pressing portion 12 can be fixed to the inner wall of the receiving cavity 11 through the connecting portion 22. The connecting portion 22 has a pressure-receiving surface 221, and the pressure-receiving surface 221 abuts against the pressing portion 12. When the pressing portion 12 is pressed, the movement of the pressure-receiving surface 221 drives the deformation of the cantilever portion 21.

[0042] It can be understood that the cantilever portion 21 can be connected to the inner wall on the side where the pressing portion 12 of the receiving cavity 11 is located through the connecting portion 22. And the surface of the connecting portion 22 that abuts against the pressing portion 12 is the pressure-receiving surface 221. When the pressing portion 12 is pressed, the pressure-receiving surface 221 moves under the drive of the pressing portion 12, so that the connecting portion 22 drives the deformation of the cantilever portion 21, and thus the pressure sensing assembly 3 can sense the deformation of the cantilever portion 21 to realize the corresponding function of the key module.

[0043] Optionally, as Figure 2 and Figure 3 shown, in some embodiments, both ends of the cantilever portion 21 are respectively fixed to the inner wall of the receiving cavity 11 through the connecting portion 22. One end of the cantilever portion 21 is arranged close to the pressing portion 12, and the other end of the cantilever portion 21 is arranged far from the pressing portion 12. The pressure sensing assembly 3 is arranged on the suspended portion of the cantilever portion 21.

[0044] Please refer to Figure 2 and Figure 3 , in this embodiment, both ends of the cantilever portion 21 are respectively connected to the connecting portion 22, and the connecting portion 22 at one end can be connected to the inner wall on the side where the pressing portion 12 of the receiving cavity 11 is located, and the connecting portion 22 at the other end can be connected to the inner wall of the receiving cavity 11 far from the pressing portion 12, which can ensure the firmness of the installation of the cantilever portion 21 in the receiving cavity 11. The pressure sensing assembly 3 can be arranged on the suspended portion of the cantilever portion 21. When the pressing portion 12 is pressed, the deformation amount of the suspended portion of the cantilever portion 21 is more obvious. In this way, the signal amount of the pressure sensing assembly 3 sensing the deformation of the cantilever portion 21 is stronger, which can further improve the reliability of the pressure sensing assembly 3.

[0045] Optionally, in some embodiments, a limiting groove 111 is formed on the inner wall of the receiving cavity 11, and at least part of the connecting portion 22 is embedded in the limiting groove 111 for connection.

[0046] As Figure 4 shown, the connecting portion 22 can be connected to the inner wall of the receiving cavity 11 by at least partially being embedded in the limiting groove 111 on the inner wall of the receiving cavity 11, so as to realize suspending the cantilever portion 21 in the receiving cavity 11. When installing the bracket 2 in the receiving cavity 11, the bracket 2 can be put into the receiving cavity 11 with appropriate force, so that at least part of the connecting portion 22 is embedded in the limiting groove 111, achieving the purpose of fixing the bracket 2 in the receiving cavity 11, and the whole structure is assembled more simply and quickly.

[0047] Optionally, in some embodiments, the bracket 2 further includes a limiting portion 23. The limiting portion 23 is disposed on one side of the connecting portion 22. When the connecting portion 22 is fixed in the limiting groove 111, the limiting portion 23 abuts against the inner wall of the accommodating cavity 11 where the limiting groove 111 is formed for limiting.

[0048] As Figure 4 shown, in this embodiment, the bracket 2 may further include a limiting portion 23. The limiting portion 23 may be disposed on the connecting portion 22 or at the position where the cantilever portion 21 is connected to the connecting portion 22. For example, when a part of the connecting portion 22 is embedded in the limiting groove 111, the limiting portion 23 may be disposed on the connecting portion 22. When the connecting portion 22 is entirely embedded in the limiting groove 111, the limiting portion 23 may be disposed at the position where the cantilever portion 21 is connected to the connecting portion 22, so that the limiting portion 23 can abut against the inner wall of the accommodating cavity 11 where the limiting groove 111 is formed, achieving the purpose of restricting the displacement of the connecting portion 22 in the limiting groove 111.

[0049] It can be understood that when the pressing portion 12 is pressed, if the connecting portion 22 displaces in the limiting groove 111, it will affect the deformation amount of the cantilever portion 21, and further cause the signal strength sensed by the pressure sensing component 3 to be weak. Based on this, the limiting portion 23 can, while fixing the bracket 2 in the accommodating cavity 11, act on the cantilever portion 21 with the pressing force received by the pressing portion 12 to a greater extent, so that the cantilever portion 21 has a greater deformation amount under the same pressing force, thereby effectively improving the signal strength of the pressure sensing component 3.

[0050] Optionally, in some embodiments, the pressing portion 12 of the accommodating cavity 11 is provided with a limiting groove 111, and the bottom of the accommodating cavity 11 opposite to the pressing portion 12 is also provided with a limiting groove 111. The limiting groove 111 extends along a direction parallel to the pressing portion 12. The connecting portions 22 at both ends of the bracket 2 are respectively embedded in the limiting groove 111 of the pressing portion and the limiting groove 111 at the bottom; when the pressing portion 12 is pressed, the connecting portion 22 embedded in the pressing portion 12 moves to drive the deformation of the cantilever portion 21;

[0051] Or

[0052] On the first side wall and the second side wall adjacent to the pressing part 12 in the accommodating cavity 11, limiting grooves 111 are provided. The first side wall and the second side wall are opposite to each other. One end of the cantilever part 21 close to the pressing part 12 is connected to the limiting groove 111 provided on the first side wall through a first connecting part, and the other end of the cantilever part 21 far from the pressing part 12 is connected to the limiting groove 111 provided on the second side wall through a second connecting part. Limiting parts 23 are formed by the surfaces of the first connecting part and the second connecting part protruding; when the bracket 2 is arranged on the main body 1, the limiting part 23 of the first connecting part abuts against the first side wall, and the limiting part 23 of the second connecting part abuts against the second side wall.

[0053] In this embodiment, as Figure 5 and Figure 6 shown, the pressing part 12 can be located at the top of the accommodating cavity 11. Therefore, limiting grooves 111 can be respectively provided at the top and the bottom of the accommodating cavity 11, and the limiting grooves 111 extend along the direction parallel to the pressing part 12. The connecting parts at both ends of the bracket 2 can be respectively embedded in the limiting grooves 111. When the pressing part 12 is pressed, the connecting part 22 embedded in the pressing part 12 can move, thereby driving the cantilever part 21 to deform.

[0054] As Figure 4 shown, the limiting grooves 111 can also be provided on two opposite side walls of the accommodating cavity 11, and the two side walls are adjacent to the pressing part 12. Both ends of the cantilever part 21 are respectively embedded in the limiting grooves 111 on the two side walls through the connecting parts 22, so as to be suspended in the accommodating cavity 11. One end of the cantilever part 21 is close to the pressing part 12, and the other end is far from the pressing part 12. Limiting parts can be formed by the surfaces of the connecting parts 22 at both ends of the bracket 2 protruding. When the bracket 2 is arranged on the main body 1, the limiting parts of the connecting parts 22 at both ends of the bracket 2 can respectively abut against the two side walls.

[0055] In this way, both ends of the bracket 2 can be firmly clamped by the limiting grooves 111, and the whole structure is simply assembled and effectively ensures the installation strength of the bracket 2.

[0056] Optionally, please refer to Figure 7 and Figure 8 , in some embodiments, the fixed end of the cantilever part 21 is connected to the main body 1, and a pressing member 13 is provided between the free end of the cantilever part 21 and the pressing part 12; the fixed end of the pressing member 13 is connected to the pressing part 12, and the free end of the pressing member 13 is opposite to the free end of the cantilever part 21; the pressure sensing assembly 3 is arranged between the fixed end of the cantilever part 21 and the free end of the cantilever part 21; when the pressing part 12 is pressed, the free end of the pressing member 13 abuts against the free end of the cantilever part 21 and drives the free end of the cantilever part 21 to move, causing the cantilever part 21 to deform.

[0057] As Figure 7 andFigure 8 As shown, the fixed end of the cantilever 21 can be fixed to the inner wall of the accommodation cavity 11, and the free end of the cantilever 21 is suspended without contacting the accommodation cavity 11. The pressure sensing component 3 is provided between the fixed end and the free end of the cantilever 21, and the cantilever 21 does not deform when not under force. A pressing member 13 is provided in the accommodation cavity 11. The fixed end of the pressing member 13 is connected to the pressing portion 12, and the free end of the pressing member 13 faces the free end of the cantilever 21. When the pressing portion 12 is pressed, the free end of the pressing member 13 can abut against the free end of the cantilever 21 and drive the free end of the cantilever 21 to move, causing the cantilever 21 to deform. In this way, since the free end of the cantilever 21 is completely suspended in the accommodation cavity 11, the force required for its deformation is smaller. In other words, when the pressing member 13 abuts against the free end of the cantilever 21 under the action of the pressing force, the pressing member 13 can drive the free end of the cantilever 21 to move, thereby deforming the cantilever 21, effectively increasing the deformation amount of the cantilever 21, and further increasing the signal strength of the pressure sensing component 3.

[0058] In some examples, when the pressing portion 12 is not pressed, there is a gap between the pressing member 13 and the free end of the cantilever 21. This can avoid the situation where the cantilever 21 is always in a deformed state due to the installation error of the pressing member 13, thereby further improving the accuracy of the function detection of the key module.

[0059] Optionally, in some embodiments, a support block 14 is provided at the bottom of the accommodation cavity 11 opposite to the pressing portion 12; the fixed end of the cantilever 21 is connected to the support block 14, so that the free end of the cantilever 21 is suspended above the bottom.

[0060] As Figure 7 and Figure 8 shown, a support block 14 can be provided at the bottom of the accommodation cavity 11. The support block 14 can provide a supporting force for the fixed end of the cantilever 21, so that the free end of the cantilever 21 can be suspended above the bottom. When the pressing portion 12 is pressed, the free end of the cantilever 21 moves under the abutting action of the pressing member 13, thereby causing the cantilever 21 to deform.

[0061] It can be understood that the pressure sensing component 3 itself has a certain weight. When the free end of the cantilever 21 is completely suspended, it may affect the deformation of the cantilever 21, resulting in inaccurate function detection of the key module. Based on this, the support block 14 can also contact one side wall of the accommodation cavity 11 to further provide sufficient supporting force and improve the situation where the cantilever 21 deforms under the influence of the gravity of the pressure sensing component 3.

[0062] Optionally, in some embodiments, a limiting block 15 is provided at the bottom of the accommodating cavity 11 opposite to the pressing portion 12. The limiting block 15 is disposed opposite to the free end of the cantilever portion 21 to define the moving distance of the free end of the cantilever portion 21.

[0063] In this embodiment, as Figure 7 and Figure 8 shown, a limiting block 15 is also provided at the bottom of the accommodating cavity 11 for the position of the free end 13 of the cantilever portion 21. When the pressing member 13 abuts against the free end of the cantilever portion 21 and drives the free end of the cantilever portion 21 to move downward, the limiting block 15 can abut against the free end of the cantilever portion 21 to limit the moving distance of the free end of the cantilever portion 21. Furthermore, it can prevent the cantilever portion 21 from being deformed excessively due to force, which may cause the pressure sensing component 3 to fail, effectively improving the reliability of the pressure sensing component 3 and extending the service life of the pressure sensing component 3.

[0064] Optionally, in some embodiments, pressure sensing components 3 are respectively attached to both sides of the cantilever portion 21.

[0065] Please refer to Figure 9 , the number of the pressure sensing components 3 can be multiple. For example, two groups of pressure sensing components 3 can be respectively attached to both sides of the cantilever portion 21. The two groups of pressure sensing components 3 can jointly sense the deformation of the cantilever portion 21 when the cantilever portion 21 is deformed, thereby increasing the signal amount of the pressure sensing components 3, and further improving the accuracy of the function detection of the key module.

[0066] An embodiment of the present application can also provide an electronic device, and the above key module can be installed on the electronic device.

[0067] It can be understood that the electronic device can include a mobile phone, a tablet computer, a handheld computer, a wearable device, etc. Among them, the main body 1 in the key module can be a housing structure such as the back shell, the cover plate or the middle frame of the electronic device.
