The button is pressed on the basis of the initial state to swing 15 ° backwards, and the pressed state is shown in fig. 4, 5 and 6. Referring to fig. 7 again, the solid line part is in a state before the elastic member 30 is pressed, the dotted line is in a state after the elastic member 30 is pressed, the fixing position of the elastic member 30 moves along with the button 20, and the pressing position of the elastic arm 304 on the panel (i.e. the second end 302 described below) slides downward to offset the amount of deformation; the elastic member 30 is hardly deformed so that the pressing force changes little during the pressing of the button 30.

If the elastic member 30 of the present embodiment is fixed in the conventional fixing manner, that is, the elastic member 30 is fixed on the panel 10, the elastic arm 304 is pressed against the button 20 and also swings 15 ° backward, the change of the elastic member 30 is as shown in fig. 8, the solid line part is in the state before pressing, the dotted line is in the state after pressing, and the deformation amount is large since the elastic member is bent from the fixing point a. Therefore, compared with the existing product, the deformation quantity of the elastic piece 30 is greatly eliminated, the button 20 is labor-saving to press, and the pressing hand feeling is better.

Further, in this embodiment, the elastic member 30 is a strip-shaped elastic sheet, the elastic member 30 is in an arch structure, a concave portion 303 is disposed at a middle position of the elastic member, the button 20 is formed with a clamping seat 21 having a clamping opening 211, the elastic member 30 is disposed in the clamping opening 211 of the clamping seat 21 in a penetrating manner, a first end 301 and a second end 302 of the elastic member are respectively pressed against the button 20 and the panel 10, and the concave portion 303 at the middle position of the elastic member 30 is fixedly clamped in the clamping seat 21 by an elastic force of the elastic member 30, so as to achieve assembly of the elastic member 30. The elastic section from the recess 303 to the second end 302 of the elastic element 30 is the elastic arm 304. By adopting the mode, the disassembly and assembly can be facilitated, namely, during assembly, the first end 301 of the elastic piece 30 is penetrated from the bayonet 211, the arched middle position of the elastic piece 30 is pressed down, the arched middle position is made to cross the bayonet 211 until the concave part 303 is clamped in the clamping seat 21, at the moment, the first end 301 and the second end 302 of the elastic piece are respectively pressed on the button 20 and the panel 10, a fixed section is arranged between the first end 301 and the concave part 303, and an elastic section is arranged between the concave part 303 of the elastic piece 30 and the second end 302 thereof, namely the elastic support arm 304.

The elastic sheet of the arch structure has a raised elastic force, so that the stability of the structure is ensured, and the assembly is convenient. And when dismantling, press the middle position of the elastic component 30, make the concave part 303 break away from the support with the card bed 21, then withdraw again, can realize dismantling.

More specifically, a guiding slope 25 is arranged between the abutting position of the first end 301 of the elastic element 30 and the button 20 and the clamping seat 21; during the penetration assembly, the assembly can be completed under the guiding action of the guiding slope 25, so that the assembly action is smoother.

Specifically, the first end 301 of the elastic element 30 is provided with a limiting structure at a pressing position on the button 20, and more specifically, the limiting structure is a protruding portion 22 standing on two sides and integrally extending from the button 20.

Of course, in other embodiments, the pressing protrusion 24 may protrude from the surface 101 of the panel 10, which is not limited to this, and is more convenient for pressing operation.

Further, in this embodiment, the rear surface 102 of the panel 10 further extends backward to form a rear blocking hook 13, and the button 20 is pressed to swing backward to a certain angle and then abut against the blocking hook 13, so as to be limited by the blocking hook 13, thereby preventing damage to internal components due to an excessive pressing stroke.

Further, in this embodiment, the button 20 has hinge supports 23 respectively extending from two ends of the upper side thereof and is hinged to the panel 10 through the two hinge supports 23, and the elastic member 30 is disposed between the two hinge supports 23, so that the force distribution is more uniform. And the hinged support 23 is extended from the two ends of the upper side for hinging, and when the button 20 returns, the self gravity of the button also plays a role, so that the return effect is better. Of course, in other embodiments, the hinge support 23 may be extended to be hinged on other sides (such as left side, right side or even lower side), and the elastic member 30 is completely relied on to return when the hinge support 23 is hinged on the left side or the right side; the elastic member 30 also overcomes the weight of the button 20 and is less effective when the hinge support 23 is extended at the lower side for hinge.
