When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a first schematic structural diagram of a key module according to an exemplary embodiment. As shown in fig. 1, the key module includes:

a key body 101 having an elastic member;

the guide posts 102 are fixed on two sides of the key body 101;

a sliding part, two ends of which are provided with clasps 103; the embracing ring 103 is sleeved outside the guide post 102;

the sliding part has an external force action, moves towards the key body 101 along the guide post 102 and acts on the key body 101 and the elastic part; the sliding part has no external force, and the elastic part recovers deformation, so that the sliding part moves along the guide post 102 towards the direction departing from the key body 101 and is separated from the key body 101.

In the embodiment of the present disclosure, the key module may be used to implement a key function, where the key function includes a power on function, a power off function, or a volume adjustment function, and the embodiment of the present disclosure is not limited.

The key body is provided with an elastic piece, and the elastic piece can elastically deform under the action of external force and recover the deformation when the external force is cancelled. The elastic element includes a spring plate or a spring, and the embodiment of the disclosure is not limited.

In the embodiment of the disclosure, the key body comprises the key circuit, and when the elastic member deforms, the key circuit generates the key signal, so that the corresponding function can be realized through the key signal. For example, the power is controlled to be turned on or off by a key signal.

The guide post is used for guiding and has a fixed guiding direction. For example, the guide direction includes a direction toward the key body or a direction away from the key body. For another example, the guiding direction further includes an X-axis direction or a Y-axis direction in a three-dimensional cartesian coordinate system, and the embodiments of the present disclosure are not limited.

Illustratively, the guiding columns include guiding cylinders or guiding square columns, and the disclosed embodiments are not limited thereto.

The embracing ring of the sliding part is sleeved outside the guide post and can slide along the guide direction of the guide post. Therefore, the sleeve of the sliding piece is sleeved on the guide post, so that the sliding piece can only move along the guide direction and cannot move along directions other than the guide direction, and the purpose of limiting the movement direction of the sliding piece is achieved.

In the embodiment of the disclosure, the inner diameter of the embracing ring is consistent with the outer diameter of the guide post. So, the guide direction motion along the guide post that the armful ring can be stable can improve the stability of motion.

In the disclosed embodiment, the guide post has a smooth outer surface. So, can reduce the frictional force between slider and the guide post, and then can realize the better motion of slider along the guide post.

The clasping rings can comprise open-loop clasping rings and can also comprise closed-loop clasping rings. When the embracing ring is a closed ring type embracing ring, the guide post is positioned in the closed ring type embracing ring and is completely surrounded by the closed ring type embracing ring; when the embracing ring is an open-loop embracing ring, the first part of the guide column is surrounded by the open-loop embracing ring, and the second part of the guide column is exposed at the opening of the open-loop embracing ring; wherein, the guide post comprises a first part and a second part.

In some embodiments, the open size of the open surround is less than or equal to 1/3 of the surround size. Therefore, the connection reliability of the hooping and the guide column can be improved.

When the sliding part has the external force, the sliding part moves towards the key body along the guide column and acts on the elastic part. That is, when the key module is pressed, the slider moves from the initial position in the guide direction of the guide post and can act on the elastic member. So, the button function that the button module corresponds can be realized based on the elastic deformation of elastic component.

When the sliding part has no external force, the elastic part recovers deformation, so that the sliding part moves along the guide post towards the direction departing from the key body and is separated from the key body. That is, when the external force is removed, the slider can be restored to the original position based on the deformation restoring force of the elastic member. In this way, the slider can be reciprocated in the guide direction.
