As shown in fig. 1 to 10, the present embodiment provides a key structure, which includes a housing 1, a key assembly and a driving device. The key structure can be applied to electronic equipment such as mobile phones, tablet computers and intelligent watches, and can well protect physical keys.

Specifically, a through hole 11 is provided in a side wall of the casing 1, and referring to fig. 3, the through hole 11 is used for installing a key cap 23, so as to implement a pressing or translating operation of the key cap 23.

In this embodiment, the key assembly is disposed inside the casing 1. The key assembly comprises a first key main body 21, a second key main body 22 and a key cap 23, wherein the key cap 23 extends out of the shell 1 from the through hole 11; the key cap 23 moves in a first direction and presses and activates the first key body 21. The key cap 23 moves in the second direction, pressing triggers the second key body 22.

The first direction may be a direction perpendicular to the side wall of the housing 1 where the through-hole 11 is located, and the second direction may be a direction parallel to the side wall of the housing 1 where the through-hole 11 is located. In operation, the first key body 21 can be pressed and activated by pressing the key cap 23, and a translation operation such as upward movement, downward movement, leftward movement, downward movement, and the like can be performed to activate the second key body 22.

More specifically, the driving device is connected to the first key main body 21, and when the key cap 23 triggers the second key main body 22, the driving device drives the first key main body 21 to move toward the key cap 23 or move away from the key cap 23.

For example, the first key body 21 is triggered by pressing the key cap 23 to perform function adjustment on the electronic device, and after the function adjustment on the electronic device is finished, the second key body 22 is triggered by moving the key cap 23 and pressing, so that the driving device drives the first key body 21 to move in a direction away from the key cap 23, and the distance between the first key body 21 and the key cap 23 is increased. When the key cap 23 is accidentally impacted or the key cap 23 is impacted, the key cap 23 does not touch the first key main body 21, and the first key main body 21 is not excessively impacted, so that the first key main body 21 is well protected. When the electronic device needs to be adjusted again, the key cap 23 is moved and the second key main body 22 is pressed and triggered again, so that the driving device drives the first key main body 21 to move in a direction close to the key cap 23, the distance between the first key main body 21 and the key cap 23 is reduced, the key cap 23 can be pressed and triggered, and the function adjustment of the electronic device is completed. The second key main body 22 is pressed and triggered by translating the key cap 23 every time, so that the moving direction of the first key main body 21 driven by the driving device is opposite to the moving direction of the first key main body 21 when the second key main body 22 is pressed and triggered last time, the first key main body 21 can be well protected, and the pressing and triggering of the first key main body 21 are facilitated.

In the embodiment of the application, the key cap 23 is moved to the first direction, for example, the key cap 23 is pressed, so that the key cap 23 is pressed to trigger the first key main body 21, thereby realizing function adjustment of electronic equipment such as a mobile phone and a tablet computer; the key cap 23 is moved in a second direction, for example, the key cap 23 is translated, so that the key cap 23 is pressed to trigger the second key main body 22, the driving device drives the first key main body 21 to move in a direction away from the key cap 23, a gap is formed between the first key main body 21 and the key cap 23, and the distance between the first key main body 21 and the key cap 23 is also increased. Even if the key cap 23 is impacted or mistakenly impacted, the key cap 23 will not press and trigger the first key main body 21, so that the first key main body 21 can be well protected, and the service life of the key structure is prolonged.

Referring to fig. 4, 5, 9 and 10, fig. 4 and 5 are views showing a state where the first key main body 21 can press the trigger key cap 23, and fig. 9 and 10 are views showing a state where the first key main body 21 cannot press the trigger key cap 23 by increasing a distance between the first key main body 21 and the key cap 23.

As shown in fig. 10, when the first key main body 21 is in the protected state, in some embodiments, after the key cap 23 is completely pressed into the casing 1, there is still a certain gap between the key cap 23 and the first key main body 21, that is, even if the key cap 23 is completely pressed into the casing 1, the first key main body 21 cannot be pressed and triggered, so as to avoid impact or damage to the first key main body 21. When the first key main body 21 needs to return to the working state, the second key main body 22 needs to be pressed and triggered only by moving the key cap 23 again, the driving device generates an acting force in the opposite direction by moving the key cap 23 for the second time, that is, the motor drives the first key main body 21 to move in the direction close to the key cap 23, and the first key main body 21 generates a motion opposite to the motion by moving the key cap 23 every time, so that the state of the key structure is controlled.

Alternatively, referring to fig. 5, 6 and 10, the key structure further includes a resilient arm 4, one end of the resilient arm 4 is fixed to the inner surface of the casing 1, and the other end is fixed to the key cap 23, and one end of the resilient arm 4 close to the key cap 23 can move along with the key cap 23 in the first direction or the second direction.

In the above embodiment, since the elastic arm 4 has elasticity, the elastic arm 4 can return the key cap 23 when the key cap 23 is pressed, which helps to protect the key cap 23 and also helps to trigger the operation of pressing the first key main body 21 by the key cap 23. At the same time, the elastic arm 4 also helps to realize the reset of the key cap 23 after translation.

Alternatively, the key cap 23 is provided with a positioning hole 231, see fig. 8. One end of the elastic arm 4 away from the housing 1 is bent toward the key cap 23 and fixed in the positioning hole 231.

In the above embodiment, the positioning hole 231 facilitates fixing the elastic arm 4, so that the elastic arm 4 can move along with the key cap 23. The elastic arm 4 can be easily bent in the first direction, but is not easily bent in the second direction, so that the elastic arm 4 can elastically move and can be used as a rotating shaft.

Alternatively, the driving device includes a motor 31 and a screw rod 32, the screw rod 32 is mounted at the output end of the motor 31, a mounting hole 211 for the screw rod 32 to penetrate is formed on the first key main body 21, and referring to fig. 7, an internal thread corresponding to the screw rod 32 is formed on the inner surface of the mounting hole 211.

In the above embodiment, the driving device can drive the first key main body 21 to move along a straight line, so as to facilitate the first key main body 21 to move towards the key cap 23 or move away from the key cap 23, and facilitate the control of the distance between the first key main body 21 and the key cap 23.

Optionally, a rolling bearing 5 is disposed on the first key main body 21, the first key main body 21 is in rolling connection with the housing 1, and a rolling direction of the rolling bearing 5 is the same as a moving direction of the first key main body 21.

In the above embodiment, the rolling bearing 5 can drive the first key main body 21 to move better, so that the driving device can drive the first key main body 21 to move towards the key cap 23 or move away from the key cap 23.

Optionally, a track 6 is provided on the inner surface of the housing 1, the rolling bearing 5 rolling within the track 6.

In the above embodiment, the rolling bearing 5 rolls in the rail 6, and contributes to limiting the movement of the first key main body 21, so that the first key main body 21 can be moved in a direction closer to the key cap 23 or in a direction away from the key cap 23.

Optionally, the number of the rolling bearings 5 is four, the four rolling bearings 5 are respectively disposed on two opposite sides of the surface of the first key main body 21, the number of the rails 6 is two, and the rolling bearings 5 located on the same side roll along the same rail 6.

In the above embodiment, the first key main body 21 moves more stably under the driving of the four rolling bearings 5, thereby facilitating the distance adjustment between the first key main body 21 and the key cap 23, and facilitating better protection of the first key main body 21.

Optionally, a control panel 7 is further included, the driving device is disposed on the control panel 7, and both the second key main body 22 and the driving device are electrically connected to the control panel 7.

In the above embodiment, when the second key main body 22 is pressed and triggered, the driving device is controlled by the control panel 7, so that the driving device drives the first key main body 21 to move. The control panel 7 facilitates not only control of the driving device and the first key main body 21 but also mounting and fixing of the driving device.

Optionally, the first direction is perpendicular to the second direction. This allows the key cap 23 to be pressed in a first direction to activate the first key body 21 and in a second direction to activate the second key body 22. When the first key main body 21 and the second key main body 22 are pressed and triggered, the moving directions of the key cap 23 are different, so that the control of the pressing and triggering of the first key main body 21 and the second key main body 22 is facilitated, and the operation is convenient.
