[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present utility model. For ordinary technicians in this field, the present utility model can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0023] For ease of description, spatially relative terms such as "on", "above", "on the upper surface of", "upper", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.

[0024] refer to Figure 1~Figure 3 As shown, the key structure of this embodiment includes: a key body 1, a front protective cover 2, a key module printed circuit board 4, a middle support member 5, a bottom cover 6, an elastic member 7, a sealing block 8, a bottom spring plate 9, a button 10 and a striker block 11; the front protective cover 2 is fixed to the upper part of the middle support member 5, and the key body 1 is arranged inside the front protective cover 2, and the top of the key body 1 extends out of the front protective cover 2; the key module printed circuit board 4 is fixed inside the middle support member 5, and the button 10 is arranged on the lower surface of the key module printed circuit board 4; the bottom cover 6 is fixed to the lower part of the middle support member 5, and the bottom of the button 10 extends out of the bottom cover 6; the sealing block 8 fixes the edge part of the elastic member 7 to the lower surface of the bottom cover 6; the striker block 11 is arranged on the inner side of the middle part of the elastic member 7, and the outer side is fixed on the bottom spring plate 9; when the elastic member 7 is in an unstressed state, the striker block 11 is separated from the button 10, and when the elastic member 7 is subjected to a certain degree of pressure, the striker block 11 contacts the button 10.

[0025] When the button body 1 is pressed, the elastic member 7 is squeezed and deformed by the upper and bottom spring plates 9, so that the striker block 11 presses the button 10, completing the movement of the button 10, thereby realizing the key function.

[0026] In this embodiment, the front protective cover 2, the middle support 5 and the bottom cover 6 can be made of metal, and these metal shells can be made by CNC numerical control processing. The advantages of this production method are that the shell is easy to make, the processing accuracy and the consistent performance of the product are guaranteed, and the failure rate of mature technology is low, and problems can be quickly solved after they occur, thereby ensuring product quality.

[0027] In one implementation, the key structure further includes a screen 3, which is located inside the front cover 2. As an important component of modern electronic products, the screen 3 has been continuously developed and innovated in technology, bringing people a more colorful visual experience. The key structure of this embodiment can not only provide key functions, but also has some display functions, and the relevant information is directly displayed at a reasonable position in the key structure through the screen 3.

[0028] In one implementation, the gap between the screen 3 and the front protective cover 2 is filled with sealant.

[0029] In this embodiment, the sealant is used to fill the configuration gap and play a sealing role. In general, the sealant is often made of dry or non-dry viscous substances such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber as the base material, combined with inert fillers such as talcum powder, kaolin, carbon black, titanium dioxide and asbestos, and then added with plasticizers, solvents, curing agents, accelerators, etc. Sealant can be classified according to different needs and scenarios, such as elastic sealants, liquid sealing gaskets and sealing putty. The sealant in this key structure is used to prevent moisture from entering the inside of the key, protect the key structure from water erosion, and extend the service life of the key structure.

[0030] refer to Figure 3 As shown, in order to make the key structure of this embodiment have a better waterproof effect, the sealing methods of potting sealing, circumferential sealing, circumferential sealing, extrusion sealing and extrusion sealing are respectively adopted at A, B, C, D and E in the figure.

[0031] In one implementation, the button body 1 is made of transparent glass, and its high light transmittance allows the light source or pattern below the button body 1 to be clearly displayed, thereby enhancing the visual effect and user experience. In addition, the glass material is often made of high-strength materials such as tempered glass, which has high hardness and impact resistance, and can resist a certain degree of external impact and wear.

[0032] In one implementation, the key structure further includes a screw 12, which passes through the bottom spring plate 9, the elastic member 7 and the striker block 11 to fix the bottom spring plate 9, the elastic member 7 and the striker block 11 together. Of course, the screw 12 in this embodiment can be a screw with a sealing function, that is, a sealing screw, which not only plays a fixing role, but also ensures that the key structure has good sealing performance.

[0033] In one implementation, the middle support member 5 and the front protective cover 2 , as well as the middle support member 5 and the bottom cover 6 are connected by sealant.

[0034] As mentioned above, the sealant in the key structure is used to prevent moisture from entering the interior of the key, protect the key structure from water erosion, and extend the service life of the key structure.

[0035] In this embodiment, the waterproof design of the key structure of the whole machine can enable the key structure itself to be immersed in water for a long time to work. The internal space of the screen 3 can be sealed with sealant, the gaps between the middle support member 5 and the front protective cover 2, and between the middle support member 5 and the bottom cover 6 can be sealed with sealant, and the moving part of the button 10 can be sealed by extrusion deformation of a waterproof film.

[0036] In one implementation, the elastic member 7 is an elastic member 7 with a waterproof function.

[0037] In one implementation, the external dimensions of the key structure are 35 mm long × 30 mm wide × 27.6 mm high. Furthermore, the effective stroke of pressing is 2.0 mm. Figure 1 As shown, the appearance length, width and height of the key structure are respectively as follows Figure 1 The x, y and z directions are shown in FIG.

[0038] The key structure provided in this embodiment has a simple structure, is stable and reliable, has a compact appearance, a good pressing feel, and is dustproof and waterproof.

[0039] This embodiment further provides an electronic device, including the key structure in the aforementioned embodiment, which will not be described in detail here.
