Embodiment Construction

[0015] see figure 1 , which is a perspective view of a key device 10 in a preferred embodiment. The key device 10 includes a key body 100 , a circuit board 200 and a switching mechanism 300 located between the key body 100 and the circuit board 200 .

[0016] Please also see figure 2 , the key body 100 includes a housing 110 and a cylindrical first pressing portion 130 and five cylindrical second pressing portions 150 fixed on the housing 110 . The casing 110 is generally in the shape of a regular hexagonal truss, and includes a regular hexagonal pressing surface 113 and six sidewalls 115 extending in the same direction from six edges of the pressing surface 113 . Six sidewalls 115 form a first intersection line 1151 and five second intersection lines 1152 . The first pressing portion 130 is vertically disposed in the middle of the pressing surface 113 and located inside the casing 110 . The five second pressing portions 150 are respectively disposed on ends of the five s...

Abstract

The invention relates to a key device which comprises a key body and a circuit board. The key body is provided with a first pressing part and a second pressing part. The circuit board is provided with a first contact part and a second contact part which respectively correspond to the first pressing part and the second pressing part. The first pressing part is contacted with the first contact part so that the circuit board can generate a first electric signal in order to realize the first input function of the key device. The second pressing part is contacted with the second contact part so that the circuit board can generate a second electric signal in order to realize the second input function of the key device. The key device further comprises a switching mechanism positioned between the key body and the circuit board. The switching mechanism can be switched between a first state and a second state under the effect of external force, so that the key device is switched between the first input function and the second input function.

Description

technical field [0001] The invention relates to a key device, in particular to a key device applied to electronic equipment. Background technique [0002] With the development of various consumer electronic products, the functions of these electronic products continue to increase, and the number of corresponding buttons also increases accordingly. On the other hand, all kinds of portable products are becoming more and more miniaturized, and it is necessary to reduce the key contact area as much as possible. In order to solve the above problems, there is a design in the prior art that uses a single button to complete multiple operation instructions, that is, integrate the functions of multiple buttons into one button to realize multiple functions. A multi-function button realizes a specific function by pressing a specific position. However, during the actual operation, the user usually uses the first state of the button most of the time, and only uses the second state of th...
