Technical Field
[0001] The utility model relates to the technical field of reversing light switches, in particular to a reversing light switch for an electric vehicle. Background Art
[0002] Electric vehicles, that is, electric-drive vehicles, also known as electric-drive vehicles, are usually referred to as electric vehicles that use batteries as energy sources and convert electrical energy into mechanical energy through controllers, motors and other components to control the current size to change the speed of the vehicle.
[0003] When an electric vehicle is used by a user, there is a need for reversing operations. When reversing, in order to ensure the safety of reversing driving, the user often presses the reversing light switch to remind passing vehicles and pedestrians. At present, the reversing light switch of an electric vehicle mostly uses a pressing operation to provide a resistance pressure to a return spring to turn on the light, and then removes the resistance pressure and uses the rebound of the return spring to turn off the light to operate the reversing light. However, if a bumpy road is encountered, it is very easy to cause the return spring to reset prematurely, resulting in an interruption in the reversing light reminder process, thereby posing a safety hazard and a poor user experience. Secondly, since the reversing light switch needs to be pressed to turn on the light, and during the pressing process, dust is easily accumulated in the sliding gap, and the dust is brought into the interior of the control housing, thereby reducing the dustproof effect.

[0012] 1. The utility model adopts the design that the card block is inserted into the card slot of the switch button. When reversing, the user can press the switch button to slide it into the main housing until the spring drives the card block to be inserted into the card slot under the restriction of the limit rod. At the same time, the permanent magnet contacts the reed switch to conduct the circuit, so as to ensure the stability and integrity of the warning after the reversing light is turned on, and avoid the phenomenon of bumps causing the reversing light to be terminated prematurely. Subsequently, after reversing, the user only needs to turn the switch button, and the switch button drives the groove cylinder to perform a limited rotation outside the limit turntable of the push rod until the card block is released from the card slot, and the reset spring drives the permanent magnet of the push rod and the reed switch to release the connection relationship of the circuit, which is convenient for the user to operate.
