In the present embodiment, the key 140 is a mechanical pressing structure, and the key 140 can be used for performing an input function. When a user presses the key 140, the key 140 moves into the cavity 101 and can cause a change in current or voltage in the control circuit, thereby generating a trigger signal to perform an input function. For example, keys 140, when pressed, may adjust the volume of electronic device 100, or perform a lock/unlock function, or perform a select function. In some embodiments, the support plate 150 has a bar shape, the support plate 150 is disposed in the cavity 101, and one end of the support plate 150 is inserted into the groove 106 of the housing 110. Further, in some embodiments, the support plate 150 has a length of 20 mm to 30 mm. For example, in one embodiment, the support plate 150 has a length of 27 millimeters. In other embodiments, the length of the supporting plate 150 may be adaptively designed according to the size of the electronic device 100, for example, the length thereof may be 23 mm, or 25 mm, or 28 mm, etc.

Referring to fig. 4, a fastener 160 penetrates the support plate 150 and is coupled to the housing 110 so that the support plate 150 can limit the moving range of the key 140. Specifically, in some embodiments, the fastener 160 is a screw. A screw passes through the support plate 150 and is screw-coupled to the housing 110 to securely fix the support plate 150 to the housing 110. Further, in the embodiment of the present application, the number of the fastening members 160 is 1, so that the number of the threaded holes provided in the housing 110 is small, the installation space of the fastening members 160 is saved, and the limit structure of the key 140 is simplified. The supporting plate 150 is made of metal, such as stainless steel or spring steel, and has relatively high structural strength. The support plate 150 may be formed by extrusion, casting, or press forming. After one end of the supporting plate 150 is inserted into the groove 106 and the supporting plate 150 is fixed to the housing 110 by the fastener 160, when the user presses the key 140, the supporting plate 150 can better support the key 140 and the related structures and limit the moving range of the key 140. With such a configuration, the convenience of assembling the support plate 150 can be improved, and the manufacturing cost of the electronic apparatus 100 can be reduced.

Further, in the present embodiment, two mounting holes 105 are provided, and the two mounting holes 105 are located on the same side of the housing 110. For example, in an embodiment where the housing 110 is rectangular frame-shaped, the two mounting holes 105 are located on the same side of the rectangle. The keys 140 may include a first key 141 and a second key 143, the first key 141 being disposed in one of the mounting holes 105, and the second key 143 being disposed in the other mounting hole 105. The structure of the first button 141 may be the same as that of the second button 143 to improve the versatility of the button 140 and facilitate disassembly and maintenance. Of course, the structure of the first key 141 may be different from that of the second key 143. For example, in the embodiment of the present application, the length of the first key 141 is smaller than that of the second key 143. This arrangement facilitates the user to distinguish the different keys 140 to improve the convenience of use. In some embodiments, the material of the first button 141 may be a metal such as an aluminum alloy, a magnesium alloy, or stainless steel. In other embodiments, the material of the first button 141 may be a nonmetal, such as ceramic, plastic, etc. Of course, in other embodiments, the first key 141 may adopt a plating structure, for example, the main body of the first key 141 may be metal or nonmetal, and the outer surface of the main body is plated with a metal coating and other protective layers.

Further, in some embodiments, an extension of the axis of the fastener 160 passes through the second key 143. This arrangement can maintain the structural stability of the portion of the support plate 150 covering the second button 143 when the user presses the second button 143, thereby improving the reliability of the cantilever beam structure. Of course, in some embodiments, other structures or other devices of the housing 110 may be utilized to support the side of the cantilever beam structure facing away from the second key 143 to ensure the reliability of the cantilever beam structure.

In the wearable device, one end of the supporting plate 150 is inserted into the groove 106 of the housing 110, and the supporting plate 150 is connected to the housing 110 through the fastener 160, so that the number of the fasteners 160 is reduced due to the matching of the groove 106 and the supporting plate 150, and the installation space of the limiting structure of the key 140 is saved.
