Embodiment 1

[0022] Embodiment 1: It is applied to the occasion where it is connected with the mechanism device that needs to obtain the signal and then moves accordingly. This example is used to obtain the movement signal of the door opening in the vehicle; it solves the problem that the movement stroke of the door lock lever of each model is different and the installation point is difficult to choose problem; if the motion signal can be obtained bidirectionally, the installation point will not be a problem. as attached figure 1 As shown, it includes a reciprocating action part 1, a housing part 2, a bidirectional stop member 3, a locking torsion spring 4, a sliding boss 5, an outer lead 6, a conductor part 7, a return spring 8 and an unlocking part 9. Described reciprocating action part 1, is to take thickness 0.5 millimeter, the spring steel sheet of width 2 millimeters is formed into clockwork disk shape, and the device of the straight bar shape of outer leading end is long 50 millimet...

Embodiment 2

[0023] Embodiment 2: as attached figure 2As shown, it includes a reciprocating action part 1 , a housing part 2 , a bidirectional stop member 3 , a locking torsion spring 4 , a sliding boss 5 , a return spring 8 , an unlocking part 9 and a contact switch 10 . The said reciprocating element 1 is consistent with the first embodiment. The housing part 2 is provided with a fixed cavity for the touch switch 10 at the lower part as shown in the figure; the rest of the arrangement is consistent with that of the first embodiment. The two-way stop member 3 , as shown in the figure, has the same upper part as that in Embodiment 1; the lower part is provided with a concave triangular structure for conducting the contact switch 10 . The locking torsion spring 4 , sliding boss 5 , return spring 8 and unlocking member 9 are consistent with the first embodiment. The touch-on switch 10 uses two Alps SPVL series 3-Wag three-way action switches, which are arranged side by side on the cavity ...

Embodiment 3

[0024] Embodiment 3: as attached image 3 As shown, it includes a reciprocating action part 1, a housing part 2, a two-way stop member 3, a locking torsion spring 4, a sliding boss 5, a return spring 8, an unlocking part 9, a contact switch 10 and a locking part 11 . The reciprocating action part 1 and the housing part 2 are consistent with the second embodiment. The two-way stop member 3, as shown in the figure, has a movable groove-shaped cavity of the locking piece 11 on the top of the double-action piece 1, which is bidirectionally symmetrical and conical, and the rest is the same as that of the embodiment 2 agree. The locking torsion spring 4 , return spring 8 , unlocking member 9 and contact switch 10 are consistent with the second embodiment. Owing to being provided with locking part 11, realize its effect to shorten the length of above-mentioned example sliding boss 5 and improve its position height. The locking member 11 is made of a PC material ball with a diamet...

Abstract

The invention discloses a method capable of forward and backward contacting and stroke changing and a structure of the method capable of forward and backward contacting and stroke changing. The structure comprises a reciprocating moving part, a bidirectional locking member, a contact switch and a shell piece, wherein the bidirectional locking member is cooperated with the reciprocating moving part, bidirectionally drives the reciprocating moving part to realize self-locking following, enables the reciprocating moving part to continuously move through the limiting unlocking of two ends and automatically resets after unlocking the reciprocating moving part, and the contact switch is arranged on the shell piece; and the reciprocating moving part is connected with a mechanism device for obtaining actuating signals and follows the mechanism device under the self-locking action of the bidirectional locking member, the reciprocating moving part can continuously move and the bidirectional locking member can smoothly reset under the self unlocking of the two ends and automatic setting after unlocking, and the contact switch can be connected in time and a contact point can randomly varied through forward and backward directional movements, so that the applicable stroke of the structure cannot be limited by the movable space of the shell piece. The structure can be conveniently suitable for touch or inductive connection switches, has strong universality and is easy to implement.

Description

technical field [0001] The invention relates to the field of universal switch contact, in particular to a device capable of forward and reverse contact and variable stroke that can be applied to obtain action signals of various mechanism devices. Background technique [0002] At present, there are many known ways to obtain the action signals of various mechanism devices, but generally they are not universal; to obtain the action signals of the devices from the mechanisms already in use, and the spatial location is limited, and the use is difficult. When there are reliable and durable requirements, qualified products are not so easy to find; when the action stroke and contact point of the mechanism device will change, or even when there is a forward and reverse action signal of the mechanism device, it is easier become a more difficult problem. Contents of the invention [0003] The purpose of the present invention is to overcome the lack of versatility of the prior art, t...
