Referring to fig. 8, fig. 8 is a schematic structural disassembly diagram of an electronic device according to another embodiment of the present application, where the electronic device includes a housing 20, a key assembly 10, a touch switch 30, and a circuit board 40. Unlike the previous embodiment, the electronic device in this embodiment further includes a support plate 50, and the support plate 50 may be disposed in the housing 20.

Optionally, referring to fig. 9 to 11 together, fig. 9 is a schematic partial structure diagram of the electronic device in the embodiment of fig. 8, fig. 10 is an enlarged schematic structural diagram of a position a in fig. 9, fig. 11 is a schematic partial sectional structural diagram of the electronic device in the position of a key assembly in the embodiment of fig. 8, and a protruding portion 51 is disposed on the support plate 50 corresponding to the position of the mounting hole 23 on the housing 20; as described in the foregoing embodiments, the key cap 200 is provided with a touch protrusion 230 for triggering the touch switch 30; the key cap 200 is provided with a boss 240, and the key cap 200 can rotate relative to the elastic support 100.

Referring to fig. 12, fig. 12 is a schematic view of a partial structure of an electronic device in a working state of a key cap, in fig. 12, the key cap 200 is rotated to a state where the protruding portion 51 of the supporting plate 50 is supported by the protruding portion 240, and the protruding portion 51 is used for limiting the key cap 200 to move in a direction toward the touch switch 30, so that the touch protrusion 230 of the key cap 200 cannot trigger the touch switch 30. In this state, the key cap 200 cannot be pressed down, and the self-locking and false touch prevention functions can be realized.

Referring to fig. 13, fig. 13 is a schematic view of a partial structure of an electronic device in another working state of a key cap, in which a boss 240 of the key cap 200 and a protrusion 51 of a bracket plate 50 are in a staggered and non-overlapping state in space, the key cap 200 is pressed to move the key cap 200 inward (toward the touch switch 30), and a touch protrusion 230 of the key cap 200 presses the touch switch 30 on the circuit board 40 to realize switch triggering; because the boss 240 of the key cap 200 and the protruding portion 51 of the supporting board 50 are spatially staggered, the boss 240 does not abut against the protruding portion 51 in the pressing process (i.e., the boss 240 does not interfere with the protruding portion 51 in the pressing process), and the key cap 200 can be smoothly pressed down, thereby realizing the function of a common key. After the key cap 200 is released, the key cap 200 is reset to the original position by the elastic arm 120 of the elastic support 100, and a switch triggering action is completed.

When the key cap 200 is rotated, the key cap boss 240 and the protrusion 51 of the support plate 50 are easily overlapped in a space under the guiding action of the inclined surface 242 of the boss 240, because a user needs to provide a friction force between the outer end surface of the key cap (i.e., the concave-convex pattern 211 in the foregoing embodiment) by using a pressing force in the process of rotating the key cap 200, the key cap 200 needs to move toward the inside (i.e., toward the touch switch 30), and the key cap 200 can be conveniently rotated to a position where the top surface of the key cap boss 240 is opposite to the top surface of the protrusion 51 under the guiding action of the inclined surface 242 of the boss 240.

In the electronic equipment in the embodiment of the application, the key assembly is in a two-piece structure, namely the key cap and the elastic support are connected by adopting a simple buckle, the key cap can be quickly disassembled from the key assembly, and the single key cap can be replaced and the problem can be replaced badly; the key cap can be disassembled from the middle shell assembly to quickly replace defective products, so that the associated scrapping cost is greatly reduced, the loss cost is reduced to the greatest extent, and the cost is saved (the cost of the shell assembly in a large-size structural assembly is generally 100-200 times that of the key cap, and the cost is higher); because the key cap is an appearance part, different appearance patterns and forms can be customized according to different requirements, and the customization requirements are realized; because press the key cap and can disassemble fast from the mesochite subassembly, consequently can the fast switch over different grade type press the key cap, promote the design flexibility, satisfy the diversified demand of customization. The two-piece key assembly structure has a common key function state and a self-locking key function state, and the two states can be switched by simply rotating the key cap; the key in the locking state can prevent false triggering, and reduce unconscious false triggering and operation false triggering of unnecessary personnel; the two-piece key assembly structure has the advantages of simple assembly, simple structure, lower cost and small influence on cost; the middle shell assembly cannot be scrapped due to the key related quality problem, the loss cost is greatly reduced, and the cost is greatly reduced; the key cap can be repaired, replaced and changed in a customized manner according to requirements, and the key cap is high in design flexibility and maintenance flexibility.

The above description is only a part of the embodiments of the present invention, and not intended to limit the scope of the present invention, and all equivalent devices or equivalent processes performed by the present invention through the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
