Referring to fig. 1, an embodiment provides a key housing structure 10, which includes: a key main body 103, wherein the key main body 103 is a shell structure with an opening 1015;

a trigger 102 disposed on the housing structure and protruding from the housing structure toward the opening 1015;

a first retainer 104 disposed at an edge of the opening 1015 and extending from the edge of the opening 1015 in a direction away from the opening 1015; and a process for the preparation of a coating,

and the second reset body 101 is arranged on the key main body 103 and protrudes outwards from the key main body 103, and the protruding direction is the same as that of the trigger piece 102.

It will be appreciated that the embodiment key housing structure 10 provides a first and second reset 104, 101 by which the first and second reset 104, 101 ensure that the key body 103 can be reset after the switch is depressed. The first retainer 104 is positioned to extend outwardly along the edges of the opening 1015 and the second retainer 101 extends forwardly along the opening 1015. That is to say, by setting the second reset body 101 to be the structure of the vertical opening 1015, the technical problem that two connected adjacent keys are easily touched by mistake can be effectively solved, and meanwhile, the problems of resilience and poor hand feeling of the split keys are also solved.

In practical use, the inner wall of the key main body 103 of the housing structure is provided with a trigger 102, which is used for pushing the trigger 102 downward when the upper portion of the key main body 103 is pressed, so as to trigger the switch, one end of the trigger 102 is fixed with the inner wall of the key main body 103, and the other end of the trigger extends outward through the opening 1015 and corresponds to the switch. A first reset body 104 extends outwards from the edge of the opening 1015 of the key main body 103, and the first reset body 104 plays a guiding role, i.e. when the key main body 103 is pressed down or reset, it plays a guiding role to prevent play to both sides. The second restoring body 101 is disposed at a position opposite to the first restoring body 104, the second restoring body 101 extends outward from the vertical opening 1015, and the second restoring body 101 has certain elasticity, so that when the key main body 103 is pressed down or restored, the key main body 103 can have a certain deformation function, i.e., a guiding function is performed, and restoration of the key main body 103 can be ensured.

Referring to fig. 1, in a further embodiment, the second peer 101 includes: a connecting piece 1011, wherein one end of the connecting piece 1011 is fixedly connected with the shell structure;

and the resetting piece 1012, the resetting piece 1012 is connected with the other end of the connecting piece 1011, and the resetting piece 1012 is a structure extending from the middle position to two sides.

It can be understood that, one end of the connecting element 1011 is connected to the inner wall of the key main body 103, and the other end is connected to the resetting element 1012, and the resetting element 1012 is extended from the middle position to two sides. And the connecting member 1011 is vertically extended upward from the opening 1015 to occupy the space on the side surface, so as to ensure that two adjacent keys can be arranged close to each other.

Referring to fig. 1 or 2, in a further embodiment, an end of the reset element 1012 is provided with a boss 1013, and the boss 1013 is protruding in a direction away from the key main body 103.

It can be understood that the protrusions 1013 are respectively provided at the two ends of the restoring member 1012, that is, the protrusions 1013 are provided at the ends to reduce the contact area of the contact surface of the restoring member 1012 and increase the deformation amount of the restoring member 1012.

In practical use, when the key main body 103 is pressed down, the middle part of the resetting piece 1012 is pressed downwards by the connecting piece 1011, and the middle part of the resetting piece 1012 can move downwards, i.e. deform, due to the distance between the middle part of the resetting piece 1012 and the contact surface caused by the bosses 1013 arranged at the two ends; when the key body 103 loses the external force, the switch and the reset member 1012 are elastic, so that the key body 103 is reset.

Referring to fig. 1, in a further embodiment, the end of the boss 1013 is provided with a gradual transition surface.

Further, the gradual transition surface is an arc surface or an inclined surface.

It can be understood that the end of the boss 1013 is configured as a gradual transition surface, so that the key main body 103 is more smoothly pressed or reset through the gradual transition surface, and the hand feeling is better. In some embodiments, the end surface of the boss 1013 is provided as an arcuate surface; in other embodiments, the end surface of the projection 1013 is provided as an inclined surface.
