The utility model provides a key device.

Referring to fig. 1 to 6, in an embodiment of the present invention, the key device includes a fixing base 10, a pressing element 30 and a sounding elastic element 50. The pressing piece 30 is arranged on the fixed seat 10 in a lifting way, a pressing block 31 is arranged on the side wall surface of the pressing piece 30, and a pressing guide surface 311 is arranged on the pressing block 31; the sounding elastic member 50 is disposed on the fixing base 10, and when the pressing member 30 descends relative to the fixing base 10, the pressing guide surface 311 abuts against and guides the sounding elastic member 50 to rotate, so that the sounding elastic member 50 collides with the fixing base 10.

In this embodiment, the fixing base 10 can be used to mount and carry the pressing element 30, the sounding elastic element 50 and other components, so that the components of the key device can be assembled into a whole. The projection of the pressing member 30 on the horizontal plane may be substantially square or rectangular, so that the shape is regular and the convenience of processing and forming is improved. Of course, it should be noted that the present invention is not limited thereto, and in other embodiments, the projection of the fixing base 10 on the horizontal plane may be a circle or other shapes. The pressing piece 30 may be used to implement a key function of the key device after being pressed by a user to input information such as letters, symbols, or numbers. The working principle can be as follows: the pressing member 30 is pressed by a user to be driven to descend, so that the optical path between the optical transmitter and the optical receiver on the keyboard body can be blocked or conducted, and at the moment, the control circuit board in the keyboard body of the keyboard can detect the blocking or conducting of the optical signal, so that the key function is realized. Of course, it may be: the pressing member 30 is driven to descend by the user, and can abut against a contact switch on the keyboard body of the keyboard, and at the moment, a control circuit board in the keyboard body of the keyboard can detect a trigger signal of the contact switch to realize a key function. In short, since the principle that the key functions by being pressed is the prior art, it is not described in detail herein. Meanwhile, the pressing element 30 can be used for abutting against and driving the sounding elastic element 50 in the descending process driven by the user. The sounding elastic element 50 can be used for generating a prompt sound by colliding with the fixed seat 10 after the pressing guide surface 311 on the pressing block 31 on the side wall of the pressed element 30 abuts and rotates, so as to play a role in pressing a prompt for a user. In addition, in order to facilitate the resetting of the pressing member 30 after the user cancels the acting force, the key device may further include a resetting elastic member (for example, a spring or a plastic member with certain elasticity), and the resetting elastic member may be disposed between the pressing member 30 and the fixing base 10. Thus, when the pressing member 30 is pressed down by a user, the return elastic member can be pressed. After the user cancels the acting force, the reset elastic piece can drive the pressing piece 30 to ascend and reset under the elastic action

When the key device according to the embodiment of the present invention is pressed by a user, the pressing member 30 is lowered with respect to the fixing base 10. At this time, the pressing guide surface 311 of the pressing block 31 on the side wall surface of the pressing member 30 may abut against and guide the rotation of the sounding elastic member 50, so that the sounding elastic member 50 collides with the fixed base 10 to generate a warning sound.
