The housing 10 as an external structure can protect the key plate 20, the elastic assembly 30 or other components contained in the first cavity 11. The bottom wall 13 is arranged opposite to the opening 12, and the first wall 14 is arranged opposite to the second wall 15. The first wall 14 is provided with a first clamping hole 141, and the second wall 15 is provided with a second clamping hole 151. The first clamping hole 141 can be clamped with the key plate 20, and the second clamping hole 151 can be clamped with the elastic assembly 30.

[0035] For the key plate 20, please refer to Figure 2 and Figure 3 The key plate 20 is provided with a first clamping portion 21, and the first clamping portion 21 is clamped in the first clamping hole 141 to fix one end of the key plate 20 to the housing 10. Further, the first clamping portion 21 comprises a first boss 211 and a first connecting piece 212. One end of the first connecting piece 212 is connected to the end of the key plate 20, and the other end is connected to the first boss 211. The first boss 211 protrudes from the first connecting piece 212, and the first boss 211 is clamped in the first clamping hole 141. The first boss 211 can be cylindrical, square or other geometric shapes. The first clamping hole 141 needs to be adapted to the shape and size of the first boss 211 in design. The first connecting piece 212 can be connected to the key plate 20 by welding, bonding or other methods. The first boss 211 and the first connecting piece 212 can be integrally formed. The key plate 20 covers the opening 12, so that the key plate 20 is arranged in the housing 10 as a whole, fully utilizing the internal space of the housing 10. The key plate 20 is kept horizontal with the opening 12, improving the touch feeling and hand feeling of the handle device 100.

[0036] For the elastic assembly 30, please refer to Figure 1 , Figure 2 and Figure 4The elastic assembly 30 is connected with the key plate 20 in the first cavity 11. The elastic assembly 30 can be arranged at an end of the key plate 20 away from the first clamping portion 21. The elastic assembly 30 comprises a second clamping portion 31, a first elastic member 32 and a second elastic member 33. The second clamping portion 31 is clamped in the second clamping hole 151, and a part of the second clamping portion 31 extends out of the shell 10 from the second clamping hole 151. The part of the second clamping portion 31 extending out of the shell 10 can be used for interacting with other components or as an operating fulcrum. The first elastic member 32 abuts between the second clamping portion 31 and the key plate 20, and the second elastic member 33 abuts between the bottom wall 13 of the shell 10 and the second clamping portion 31. The first elastic member 32 and the second elastic member 33 can be springs, elastic rubbers or the like.

[0037] When it is needed to cover the key plate 20 with the shell 10, the first clamping portion 21 of the key plate 20 can be clamped with the first clamping hole 141 of the shell 10, so that the key plate 20 partially enters the first cavity 11. A downward pressure is applied to the key plate 20, and the key plate 20 gradually enters the first cavity 11 as a whole, and the second clamping portion 31 drives the first elastic member 32 to also enter the first cavity 11. Since the second clamping portion 31 is subjected to the pressure from the shell 10, the first elastic member 32 is compressed and stores elastic potential energy. When the second clamping portion 31 moves to the position of the second clamping hole 151, the first elastic member 32 releases the elastic potential energy, so that the second clamping portion 31 is clamped in the second clamping hole 151, and the covering of the key plate 20 with the shell 10 is completed.

[0038] When it is needed to take out the key plate 20 from the first cavity 11, the second clamping portion 31 extending out of the second clamping hole 151 can be pressed, and the second clamping portion 31 gradually separates from the second clamping hole 151. The second elastic member 33 releases the stored elastic potential energy and gives the second clamping portion 31 an upward elastic force, so that the key plate 20 is ejected out of the first cavity 11. At this time, the first clamping portion 21 also partially separates from the first clamping hole 141, so as to facilitate the taking out of the key plate 20 from the first cavity 11.

[0039] In some embodiments, referring to Figure 5 The second clamping portion 31 comprises a second boss 311 and a key 312. The first elastic member 32 is partially arranged in a first recess 3111 formed at one end of the second boss 311. The first elastic member 32 abuts between the second boss 311 and the key plate 20. The second boss 311 abuts with the key 312 at the other end. The key 312 partially extends out of the shell 10 from the second clamping hole 151. Further, in combination with Figure 6The elastic assembly 30 further comprises a reset member 34, which comprises a first support plate 341 and an elastic piece 342. One end of the elastic piece 342 is connected to the first support plate 341, and the other end is abutted against the key 312 in the direction of the second wall portion 15. The first support plate 341 is connected to the bottom wall 13, and the second elastic member 33 is abutted between the first support plate 341 and the second boss 311. The elastic piece 342 has a certain elasticity. During the pressing process of the key 312, the elastic piece 342 can drive the key 312 to return to the initial position. Specifically, the key 312 is connected with a first limiting portion 3121, the elastic piece 342 is abutted against the first limiting portion 3121 in the direction of the second wall portion 15 in the first cavity 11, and the first limiting portion 3121 is abutted against the second wall portion 15, thereby reducing the phenomenon that the key 312 is easily detached when the second boss 311 is detached from the key 312.
