Referring to fig. 1, the cantilever structure 100 includes a main body 110, an assembly 120, and at least two connectors 130, wherein a pressing hole 111 is provided on the main body 110 along a first direction, the assembly 120 is disposed in the pressing hole 111, and the assembly 120 can move in the pressing hole 111 along the first direction, the connectors 130 are disposed in the pressing hole 111, one end of each connector 130 is connected with the assembly 120, the other end of each connector 120 is connected with the main body 110, the connectors 130 are used for providing support for the assemblies 120, and the connectors 130 can enable the assemblies 120 to recover to an initial position after moving along the first direction. Wherein the first direction may be a vertical direction in the drawings.

The assembly 120 may be used to mount the button 200 in the key, and when the assembly 120 receives a pressing force, the assembly 120 may move in the first direction within the pressing hole 111, and when the pressing force is lost, the assembly 120 may be restored to an initial position before pressing by the connection body 130.

It can be understood that when the assembly 120 receives a pressing force, the connecting body 130 can be elastically deformed, and when the pressing force is eliminated, the connecting body 130 is restored to an initial state, so as to drive the assembly 120 to restore to an initial position.

Referring to fig. 1, in some embodiments, the connector 130 is provided with at least two. For example, two, three, four or more connecting bodies 130 may be provided, and a plurality of connecting bodies 130 may be connected to the main body 110 and the fitting body 120, respectively, to support the fitting body 120 in cooperation.

Further, when the connection body 130 has two or more, at least two connection bodies 130 are located at opposite sides of the assembly body 120, for example, when there are two connection bodies 130, two connection bodies 130 are located at just opposite sides of the assembly body 120; when there are three connectors 130, at least two of the connectors 130 are located on opposite sides of the fitting 120. That is, the above-described method supports at least the support points on both sides of the assembly 120, so that the assembly 120 is more stable, and does not sag or shake in a natural state.

It should be noted that, the above-mentioned "at least two connectors 130 are located at opposite sides of the assembly 120" is not limited to the two connectors 130 being symmetrical or centered along the central axis of the assembly 120, and the two connectors 130 only need to ensure that the two connectors can be connected to the main body 110 and the assembly 120 at opposite sides of the assembly 120.

Preferably, the two connecting bodies 130 are symmetrical or centrosymmetric along the central axis of the assembly 120, which is simple to process, and the assembly 120 is more stable in the pressing hole 111.

It can be understood that, since the connectors 130 are connected to opposite sides of the assembly 120, an included angle is formed between the first connecting portion 131 and the second connecting portion 132 in the connectors 130, so that the connectors 130 have a sufficient deformation space after receiving the pressing force, and no fracture is caused due to the interaction force between the two connectors 130.

Specifically, the connection body 130 may further include a bent portion 133, the first connection portion 131, the bent portion 133, and the second connection portion 132 are sequentially connected in the second direction, and the bent portion 133 makes the first connection portion 131 and the second connection portion 132 form an included angle. The second direction is perpendicular to the first direction, i.e. the second direction may be a horizontal direction in the drawing.

It can be seen that, in the cantilever structure 100 of the present application, at least one connecting body 130 is disposed on two opposite sides of the assembly body 120, so that two opposite sides of the assembly body 120 are supported by at least one supporting point, so that the assembly body 120 in the pressing hole 111 can be more stable, sagging can not occur and shaking or the like is not easy to occur in a natural state, and the plurality of connecting bodies 130 support the assembly body 120, so that the service life of the cantilever structure 100 is longer.

In addition, since the connection bodies 130 are located at opposite sides of the assembly body 120, an included angle is formed between the first connection portion 131 and the second connection portion 132 in the connection bodies 130, so that the connection bodies 130 can be ensured to have enough deformation space when being pressed, breakage caused by interaction force between the two connection bodies 130 can be avoided, and better pressing feeling can be provided for users.
