Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device technology, and in particular to a button mechanism and an electronic device. Background Technology
[0002] In the manufacturing process of products such as hearing aids and charging cases, button denting has become a key challenge restricting product quality and production efficiency. The button assembly process for hearing aid charging cases involves the precise fitting of multiple components. Due to design and manufacturing limitations, numerous tolerances exist between these components. These tolerances accumulate during assembly, making it difficult to precisely control the flatness of the assembled buttons, resulting in frequent button denting issues.
[0003] Under the current production model, due to differences in assembly precision and component consistency among different products, it is difficult to ensure that the buttons on every product are free of dents. Once a button dent occurs, it is necessary to disassemble and analyze the manufactured products periodically to find the root cause of the problem. This process not only consumes a lot of manpower, resources, and time, but also causes irreversible damage to the product, leading to product scrapping, significantly increasing production costs, and reducing the continuous operation capability of the production line.
[0004] Therefore, there is an urgent need for a button mechanism and electronic device to solve the aforementioned problems. Utility Model Content
[0005] Based on the above, the purpose of this utility model is to provide a button mechanism and electronic device that solves the problem of button recess caused by assembly tolerance during the assembly process, improves the reliability of the button mechanism, and reduces production costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] As a preferred technical solution for a button mechanism, the pressure regulating component has a step formed at the transition from where the flexible sheet connects to the housing to where the flexible sheet connects to the button.
[0011] As a preferred technical solution for a button mechanism, the pressure regulating component includes a first adhesive and a second adhesive. The first adhesive connects the flexible sheet to the housing, and the second adhesive connects the flexible sheet to the button. The thickness of the first adhesive is less than the thickness of the second adhesive.
[0012] As a preferred technical solution for a button mechanism, the inner wall of the housing is provided with a first positioning post, and the flexible sheet is provided with a first positioning hole that cooperates with the first positioning post, with the first positioning post passing through the first positioning hole.
[0013] As a preferred technical solution for a button mechanism, the button includes a pressing part and a flanged part. The pressing part is movably disposed through the button hole, and the flanged part is connected to the flexible sheet and abuts against the inner wall of the housing.
[0014] As a preferred technical solution for a button mechanism, the flanged portion is provided with a second positioning post, and the flexible sheet is provided with a second positioning hole that cooperates with the second positioning post, with the second positioning post passing through the second positioning hole.
[0015] As a preferred technical solution for a button mechanism, an abutting post is provided on the inner side of the pressing part; the flexible sheet is provided with a clearance hole, which is used to allow the abutting post to pass through.

[0019] The beneficial effects of this utility model are as follows:
[0020] This utility model provides a button mechanism, which is installed in the button hole of the housing of an electronic device. A pressure adjustment component is provided at the connection point between the flexible sheet and the housing and the connection point between the flexible sheet and the button. The pressure adjustment component can create a pressure difference between the pressure between the flexible sheet and the housing and between the flexible sheet and the button. This pressure difference ensures that the button is always under pressure. On the one hand, this pressure can ensure that the button is installed in the preset position of the button hole, solving the problem of denting caused by tolerance during button assembly. On the other hand, after the button is pressed, the flexible sheet provides the elastic force for the button to return to its original position.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a button mechanism installed in the button hole 11 of the housing 1 of an electronic device. The button mechanism includes a button 2 and a flexible sheet 3. Specifically, the button 2 is movably inserted through the button hole 11; the flexible sheet 3 connects the button 2 and the housing 1, and a pressure regulating component 4 is provided at the connection point of the flexible sheet 3 to the housing 1 and the connection point to the button 2. The button mechanism is installed in the button hole 11 of the housing 1 of the electronic device. The pressure regulating component 4, located at the connection point of the flexible sheet 3 to the housing 1 and the connection point to the button 2, creates a pressure difference between the pressure between the flexible sheet 3 and the housing 1 and between the flexible sheet 3 and the button 2. This pressure difference ensures that the button 2 is always under pressure. On the one hand, this pressure ensures that the button 2 is installed in a preset position in the button hole 11, solving the problem of dents caused by tolerances during button 2 assembly; on the other hand, after the button 2 is pressed, the flexible sheet 3 provides a spring force for the button 2 to return to its original position.
[0036] Preferably, the pressure regulating component 4 has a step at the transition from where the flexible sheet 3 connects to the housing 1 to where the flexible sheet 3 connects to the button 2. This step creates a height difference between the part where the flexible sheet 3 connects to the button 2 and the part where the flexible sheet 3 connects to the housing 1, thereby creating a pressure difference between the two parts of the flexible sheet 3.
[0037] In this embodiment, the pressure regulating component 4 includes a first adhesive 41 and a second adhesive 42. The first adhesive 41 connects the flexible sheet 3 to the housing 1, and the second adhesive 42 connects the flexible sheet 3 to the button 2. The thickness of the first adhesive 41 is less than the thickness of the second adhesive 42. On one hand, the first adhesive 41 serves to bond the flexible sheet 3 to the housing 1, thus connecting the flexible sheet 3 to the inner wall of the housing 1; the second adhesive 42 serves to bond the flexible sheet 3 to the button 2, thus connecting the flexible sheet 3 to the button 2. On the other hand, because the thickness of the first adhesive 41 is less than the thickness of the second adhesive 42, a step is formed between them, causing the connection between the flexible sheet 3 and the button 2 to bulge and deform away from the button 2, creating a pressure difference in different parts of the flexible sheet 3. Consequently, the flexible sheet 3 applies an elastic force to the button 2 towards the button hole 11. In this embodiment, the thickness of the first adhesive 41 is 0.1 mm, the thickness of the second adhesive 42 is 0.4 mm, and the flexible sheet 3 forms an elastic pushing force after installation.
[0038] In other embodiments, a housing 1 may be provided with a first protrusion, a button 2 may be provided with a second protrusion, a step may be formed between the first protrusion and the second protrusion, and a flexible sheet 3 may deform and generate a pressure difference after being connected to the first protrusion and the second protrusion.
[0039] Preferably, the inner wall of the housing 1 is provided with a first positioning post 12, and the flexible sheet 3 is provided with a first positioning hole 31 that mates with the first positioning post 12. When the flexible sheet 3 is assembled with the housing 1, the first positioning post 12 passes through the first positioning hole 31, which improves the assembly accuracy of the flexible sheet 3 and the housing 1 and improves the ease of assembly. In this embodiment, there are two first positioning posts 12 and two first positioning holes 31. The two first positioning posts 12 are symmetrically arranged on both sides of the button hole 11, which can prevent the flexible sheet 3 from rotating relative to the housing 1.
[0040] Furthermore, button 2 includes a pressing part 21 and a flanged part 22. The pressing part 21 is movably inserted through the button hole 11, and the flanged part 22 is connected to the flexible sheet 3 and abuts against the inner wall of the housing 1. In this embodiment, the outer peripheral area of the flexible sheet 3 is fixed to the inner wall of the housing 1, and the middle area of the flexible sheet 3 is fixed to the flanged part 22. The flexible sheet 3 elastically deforms to make the flanged part 22 press tightly against the inner wall of the housing 1, which can prevent button 2 from detaching from the housing 1 and make button 2 installed in the preset position of button hole 11. In use, the user can press the pressing part 21 of button 2, and the pressing part 21 slides under the guidance of button hole 11.
[0041] More preferably, the flanged portion 22 is provided with a second positioning post 23, and the flexible sheet 3 is provided with a second positioning hole 32 that mates with the second positioning post 23. When the flexible sheet 3 is assembled with the button 2, the second positioning post 23 passes through the second positioning hole 32, improving the assembly accuracy of the flexible sheet 3 and the button 2 and enhancing the ease of assembly. In this embodiment, there are two second positioning posts 23 and two positioning holes 32, and the two second positioning posts 23 are symmetrically arranged on both sides of the button 2, which can prevent the flexible sheet 3 from rotating relative to the button 2.
[0042] Furthermore, an abutment post 24 is provided on the inner side of the pressing part 21; the flexible sheet 3 is provided with a clearance hole 33, which is used to allow the abutment post 24 to pass through. When the pressing part 21 is pressed, the abutment post 24 passes through the clearance hole 33 and abuts against other switches 5, thus completing the signal transmission.
[0043] In this embodiment, the flexible sheet 3 can be made of silicone. The button 2 is made of silicone, and an annular deformation groove 25 is provided between the abutting post 24 and the flange 22. When the button 2 is pressed, the annular deformation groove 25 deforms, the abutting post 24 moves towards the switch 5, while the flange 22 remains attached to the inner wall of the housing 1.
[0044] Preferably, the inner wall of the housing 1 is provided with a positioning groove 13 communicating with the button hole 11, and the flange 22 abuts against the positioning groove 13. In this embodiment, when the button 2 is assembled with the housing 1, the flange 22 is embedded in the positioning groove 13, which improves the assembly accuracy of the button 2 and the housing 1, and also improves the ease of assembly.
[0045] More preferably, the flanged portion 22 is provided with a foolproof protrusion and / or a foolproof straight edge, and the positioning groove 13 matches the shape of the flanged portion 22. After the flanged portion 22 is embedded in the positioning groove 13, the positioning groove 13 provides positioning for the button 2, and the foolproof protrusion and / or foolproof straight edge can restrict the button 2 from rotating relative to the housing 1.
[0046] like Figure 3 As shown, this embodiment also provides an electronic device, including a housing 1 with a button hole 11. The electronic device also includes the aforementioned button mechanism, which is mounted in the button hole 11. By mounting the button mechanism in the button hole 11 of the housing 1, button 2 can be prevented from being recessed, thus improving the yield rate of the electronic device. In this embodiment, the electronic device can be a hearing aid or a charging case.
[0047] Furthermore, such as Figure 1 As shown, the electronic device also includes a switch 5 disposed in the housing 1, and the switch 5 is positioned corresponding to the button 2; the switch 5 generates a switching signal when the button 2 is pressed.
[0048] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
