Description

Bistable switch with manual closing and electric control closing Technical Field The invention relates to the technical field of automobile electronics, in particular to a bistable switch with manual closing and electric control closing. Background Prior art CN112599388a discloses a bistable switch, which comprises a housing, be provided with coil former, two terminal and contact bridge in the shell, the coil former is provided with a cavity sleeve pipe and coil winding, be provided with quiet iron core and movable iron core in the cavity sleeve pipe, fixedly connected with guide arm between contact bridge and the movable iron core, be provided with the steady state subassembly that is used for keeping movable iron core and quiet iron core actuation or release state on the coil former, the steady state subassembly includes reset spring, is used for pressing the compression spring of contact bridge and is used for strengthening the permanent magnetism piece of movable iron core electromagnetic attraction. The bistable switch provided by the invention has a simple structure, has a double stable state of stable conduction and stable disconnection, does not need continuous power supply of a coil, does not generate heat, ensures the dynamic balance between the internal temperature of the switch and the external environment temperature, can be normally turned on and off particularly in an extremely cold severe environment, solves the problem that an automobile cannot be normally started in an extremely cold environment in the industry, and effectively prolongs the service life of the switch. The scheme has the following defects that when a vehicle controller fails and can not provide signals for the bistable switch, the bistable switch can not be closed, the whole vehicle is not electrified, and calling rescue is needed. Disclosure of Invention The invention overcomes the defects of the prior art, and provides the bistable switch with manual closing and electric control closing, which has reasonable structural design, and when a vehicle controller fails and can not provide signals for the bistable switch, the bistable switch can not be closed, the whole vehicle is not electrified, and at the moment, the movable contact and the stationary contact can be closed by using the manual closing switch function through the rotating column, so that the power supply of the whole vehicle is realized, and the calling rescue is not needed. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a bistable switch with manual closure and automatically controlled closure, includes the casing and locates magnetic latching relay in the casing, magnetic latching relay includes base, fixed connection in the skeleton of base, install in bridge type double contact structure in the base, install in magnetism keep the drive structure on the skeleton and set up in guide arm in the skeleton, bridge type double contact structure is including movable contact and stationary contact, the movable contact passes through the guide arm with movable iron core linkage in the magnetism keep the drive structure, its characterized in that still includes: the guide sleeve is fixedly arranged on the shell; the adapter block is axially arranged in the shell in a sliding way along the guide rod, and the adapter block can slide to be abutted with the guide rod; The buffer sleeve is arranged in the guide sleeve, a guide block is arranged in the buffer sleeve, and a limit groove and a guide section communicated with the limit groove are arranged on the guide block; The rotating column is rotationally arranged in the guide sleeve and the buffer sleeve, and is connected with a rotating pin which can move along the guide section and is positioned in the limiting groove in a linkage manner, so that when the rotating column is operated to rotate, the rotating column moves relative to the buffer sleeve, the rotating column or the buffer sleeve is abutted to the guide rod, and the movable iron core is driven to move so as to realize the closing of the movable contact and the fixed contact. Through adopting above-mentioned technical scheme, compare in prior art, this scheme is through setting up the rotation post structure, when the vehicle control ware breaks down unable for bistable switch provides the signal, rotate through operating the rotation post, specifically, the rotation post has the operation hole that exposes in the guide pin bushing upper end, the hexagonal hole can be in to the operation hole, insert in the hexagonal hole through the hexagonal spanner and rotate the rotation post, make the rotation post rotate along the guide block, so make the rotation post remove relative buffer sleeve, rotation post or buffer sleeve just can with the transfer block butt, and drive the transfer block and move downwards, transfer block and guide arm butt, thereby realize moving the iron core a
