Compared with prior art, the novel automatic rebounding press button mechanism that provides of this use, because the elastic-restoring force of button automatic rebounding is provided by two U-shaped connecting rods that itself arrange, so need not additionally to increase spring element, reduced the cost of part, in addition, because what the utility model adopted is that snap fit is done simple and easy combination, need not hot melt assembling and screw, this has reduced difficulty and the cost of assembling to a certain extent, and in addition, the utility model is by being provided with guide channel and lead, guaranteed the linearity of the glide direction of described button, and the uniformity in the gap between the press section of described button and the corresponding accepting groove.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the exploded perspective view of the utility model automatic rebounding press button mechanism one preferred embodiment.
Fig. 2 is the assembling schematic diagram of the utility model automatic rebounding press button mechanism shown in Figure 1 one preferred embodiment.
[embodiment]
Fig. 1-2 is one preferred embodiment of the utility model automatic rebounding press button mechanism.Automatic rebounding press button mechanism of the present utility model is located at housing 30 interior the pressing for the user of an electronic installation and is touched the switch of being located in the described electronic installation, in the present embodiment, described automatic rebounding press button mechanism comprises a button 10 and a fixture 20, and described button 10 is fixed in the described case of electronic device 30 by described fixture 20.
Described button 10 is a symmetrical structure, is provided with successively an actuation part 13 for press section 11, one limiting sections 12 of accepting pressing force and an actuating switch.Described limiting section 12 is between described press section 11 and described actuation part 13, and described limiting section 12 offers a guide channel 120 in the centre position.Described actuation part 13 1 ends connect described limiting section 12, and the other end is that a shake-up end 130 is used for touching the switch of being located in the described case of electronic device 30.Described button 10 further is provided with the U-shaped connecting rod 14 of two elastically deformables in the bilateral symmetry of described actuation part 13, elastic-restoring force for the automatic rebounding that described button 10 is provided, described each U-shaped connecting rod 14 1 end are connected on the described limiting section 12, and the other end is provided with a blocking hole 15 for being combined with described fixture 20 blockings.Described fixture 20 is located in the housing 30 of described electronic installation and is used for fixing described button 10.
Described fixture 20 corresponding described buttons 10 are provided with an accepting groove 21, one limit convexes 22, and several snap fits 23.Described press section 11 is housed in slidably and equably the described accepting groove 21 interior users of confession and presses.Described limit convex 22 is located in the described guide channel 120, and traveling priority is not offset so that described guide channel 120 can be subject to the restriction of described limit convex 22 when described button 10 is pressed.In the present embodiment, described fixture 20 is provided with five snap fits 23, wherein two snap fits 23 collude the both sides that are located at described limiting section 12, a snap fit colludes a side of establishing described actuation part 13, and other two snap fits collude the periphery that is located at corresponding blocking hole 15 after passing two blocking holes 15 of described U-shaped connecting rod 14, are used for fixing described button 10.Described fixture 20 further is provided with two guide posts 24 in described actuation part 13 near two sides of described shake-up ends 130 to be passed through between described two guide posts 24 for described actuation part 13, so that described two guide posts 24 can limit the direction of slip of the actuation part 13 of described button 10, guarantee described actuation part 13 linear slide.
When using, the user presses described press section 11, so that inwardly slide in described press section 11, at this moment, the limiting section 12 of described button 10 can or not be offset along slided by force direction under the restriction of described guide channel 120 and described limit convex 22, described actuation part 13 equally can be under the restriction of described two guide posts 24 be slided and can be offset along user's the direction of pressing, and simultaneously, two U-shaped connecting rods 14 being located at described actuation part 13 both sides can deform owing to being under pressure, after the shake-up end 130 of described actuation part 13 touches the switch that arrives in the described case of electronic device 30, the user no longer application of force presses described press section 11, at this moment, described two U-shaped connecting rods 14 can restore to the original state owing to no longer being under pressure, and 11 meetings of described press section are returned the origin-location under the effect of the elastic-restoring force of described two U-shaped type connecting rods 14, position before namely not being pressed, by this, the present invention has realized need not to use spring to reach button automatic rebounding effect.Because what the utility model used is that snap fit fixes button 10, need not to use screw, easily assembled.By above-mentioned snap fit 23, shown in the above-below direction of button 10 be limited, by above-mentioned guide channel 120,131 and shown in limit convex 22, shown in the cooperation of guide posts 24, shown in the motion of left and right directions of button 10 be limited, shown in 11 gaps, press section of button 10 are housed in equably shown in therefore having guaranteed in the accepting groove 21 of fixture 20, and in the stroke of whole button 10, button 10 can obtain near rectilinear motion.
