When the first stress of the product disappears, the ejector block and the rotating shaft reset rightwards under the action of the spring, meanwhile, the inclined plane of the protruding rib of the rotating shaft starts to be matched with the serrated inclined plane of the second shell and moves along the inclined plane to generate axial angle deflection, the end part of the protruding rib moves to the inclined plane of the second shell to limit dead angles, then the stress is balanced, the circuit is in a conduction state, and the product enters a self-locking state.
When the product is stressed for the second time, the stress direction is as shown in figure 2, the acting force pushes the internal parts of the system to move leftwards, then, under the matching action of the inclined plane of the protruding rib of the rotating shaft and the serrated inclined plane on the left side of the second shell, the rotating shaft moves along the inclined plane to generate axial angle deflection and moves to the lowest position of the serrated inclined plane on the left end of the shell, the circuit is still conducted, and the state diagram is similar to figure 2.
When the stress of the product disappears for the second time, the ejector rod and the rotating shaft are under the acting force of the spring, the system parts are reset rightwards integrally, meanwhile, the rotating shaft and the sawtooth-shaped inclined plane of the second shell start to be matched, axial angle deviation is generated along the inclined plane movement, the protruding ribs move to the bottommost end of the inner shell rotation limiting groove, the internal circuit of the product is disconnected, the transmission block is matched with the first shell to be limited, the stress of the product is balanced, and the product returns to a free state as shown in figure 1.
The danger alarm switch for the vehicle is small in size, the internal structure of the product is compact on the premise of not increasing the size of the product, and the assembly space is saved for customers; the self-locking and long-pass circuit can be kept, after a short stress, the inclined plane of the rotating shaft of the product is clamped into the inclined plane limiting groove of the second shell, and the internal circuit of the product in the state is in a long-pass state, has no abnormal motion and is stable; the movable contact spring type sliding contact is adopted, under the working condition of small micro-current, the movable contact spring is continuously in sliding fit with the first metal sheet and the second metal sheet in a sliding mode when being switched on and switched off at each time, carbon deposition generated by arc discharge in the electrifying process on the surfaces of the two metal sheets can be removed, the self-cleaning effect is generated, good conduction of products is guaranteed, and the reliability of the products is high.
Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses an innovative design to automobile-used danger alarm switch structure under the condition that does not increase switch product volume, innovative design product inner structure for the product only need once press, just can move and keep the auto-lock state, and the circuit switch-on simultaneously, and possess manual unblock function, circuit disconnection after the unblock. The danger alarm switch for the automobile has the advantages of compact structure, simple assembly and low cost, and meets the use conditions of high requirements, energy conservation and environmental protection of the danger alarm switch product in the automobile industry.
