Embodiment

[0018] Embodiment: The switch structure includes a button, a slider 1, a housing 2, an elastic rubber pad, a PCB, and a base. Wherein the reset structure is achieved by the cooperation of two parts, the slider 1 and the housing 2, to achieve the motion deceleration effect.

[0019] There is a guide groove 3 on the inner wall of the housing 2, and the guide groove 3 is a three-section type. The guide rib is also a three-section type, including a narrow straight section 4 at the upper end, two elastic cantilevers in the middle section) and a wide straight section 6 at the lower end. There is a rectangular groove 7 on the slider 1, and the elastic cantilever 5 is located in the groove 7. The upper ends of the two elastic cantilevers 5 are fixed, the lower ends are open, and there are convex points at the ends; the guide ribs cooperate with the guide groove 3, and the upper convex point structure of the elastic cantilever 5 on the slider 1 is always in contact with the housing gui...

Abstract

The invention discloses a switch reset buffer structure. The switch reset buffer structure comprises a button, a sliding block (1) and a shell (2), wherein a guide groove (3) is formed in the inner wall of the shell (2), and the guide groove (3) is provided with a narrow upper part and a wide lower part; a guide rib is arranged on the outer wall of the sliding block (1), two elastic cantilevers (5) are arranged at the middle section of the guide rib, the upper ends of the elastic cantilevers (5) are fixed, and the lower ends of the elastic cantilevers (5) are stretched; and the guide rib is matched with the guide groove (3). According to the switch reset buffer structure, bulges on the elastic cantilevers on the sliding block are in contact with an oblique plane of the guide groove of the shell, so that the cantilevers generate elastic deformation, the cantilevers generate positive pressure for the guide groove, and component force of the positive pressure is in an opposite direction of moving the sliding block, so that the reset speed of the sliding block is decreased, and the impact effect of a component during reset is reduced.

Description

technical field [0001] The invention relates to a guiding and motion buffering structure of a linear reciprocating motion mechanism, in particular to a guiding motion structure in which the operating component is a linear reciprocating motion switch. Background technique [0002] Modern automobiles have higher and higher requirements for the comfort of the switch operation inside the cab. The operability of traditional push-type automotive switches is limited by the sliding guide structure. During the reset process of sliding parts, the process is continuously accelerated by external forces, resulting in fast reset speed. , showing a stiff operating feeling, which affects the operating comfort, and the beating sound is relatively loud when the reset speed is too fast. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reset deceleration structure for the problem that the reset acceleration of the moving parts of t...
