Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reversing light switch structures, in particular to a reversing light switch structure for an automobile. Background Art
[0002] The reversing light switch is installed at the rear of the car to illuminate the road behind the car and warn vehicles and pedestrians behind the car that the car is reversing.
[0003] At present, the reverse light switch structure of the car is mostly triggered by shifting the gear of the rear gear. After repeated use, the switch structure of the reverse light will inevitably be impacted and worn by the pushing force, resulting in insufficient durability and reduced service life. Secondly, the reverse light switch structure is generally installed on the transmission of the car. During use, if the sealing is not intervened, there is not only the possibility of foreign matter entering, but also the transmission oil pollution on the contacts will accelerate carbonization, which seriously affects the service life of the reverse switch and personal safety.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] For examples, see Figures 1 to 5The utility model provides a technical solution: a vehicle reversing light switch structure, comprising a main housing 1, a first sealing ring 3 is fixedly installed in a central through hole on one side of the main housing 1, a triggering slide column 2 that is pushed by the automobile reversing gear is slidably connected in the first sealing ring 3, a limited stop plate 4 is fixedly connected to a surface of one side of the triggering slide column 2, the limited stop plate 4 is limitedly abutted against the central through hole where the triggering slide column 2 slides, a trigger block 5 is fixedly installed on a surface of one side of the limited stop plate 4, a push rod 6 that slides against it is installed on one side of the trigger block 5, a group of symmetrical sliding grooves 7 are opened on the inner surfaces of both sides of the main housing 1, a first slide plate 8 and a second slide plate 9 are slidably connected in the slide grooves 7, and the first slide plate 8 and the second slide plate 9 are respectively fixedly connected to the surfaces of both sides of the limited stop plate 4 and the push rod 6, and a vertical slide plate 9 that penetrates and slides in the second slide plate 9 is fixedly connected on the surface of the first slide plate 8 The surfaces of the slide plate 10 and the second slide plate 9 are provided with a slot 11 for the vertical slide plate 10 to slide. A group of symmetrical fixing plates 14 are fixedly installed on the inner surface of the side of the main shell 1 away from the slide groove 7. A buffer spring 15 is welded between the fixing plate 14 and the vertical slide plate 10. A first touch sensor 16 is fixedly installed on the surface of one side of the push rod 6. A second touch sensor 17 for contact conduction with the first touch sensor 16 is fixedly installed on the inner surface of the side of the main shell 1 away from the trigger slide column 2. A reset spring 18 is welded between the push rod 6 and the inner surface of the main shell 1. The reset spring 18 is wound around the outside of the first touch sensor 16 and the second touch sensor 17. One side surface of the second touch sensor 17 passes through the outside of the main shell 1 and is fixedly connected to a wiring plug 19. The wiring plug 19 is located inside the main shell 1 and is fitted with a second sealing ring 20 around it.
[0022] More specifically, in this embodiment, when the trigger slide column 2 is pushed in the reverse gear, the trigger slide column 2 first drives the first slide plate 8 of the limit plate 4 to abut against the push rod 6, and the vertical slide plate 10 of the first slide plate 8 in the slide groove 7 slides in the notch 11 of the second slide plate 9 until the first slide plate 8 abuts against the second slide plate 9, thereby reducing the probability of the first touch sensor 16 and the second touch sensor 17 abutting against each other when the reverse gear is suddenly engaged and the reverse light switch is activated. Then, the push rod 6 drives the first touch sensor 17 along with the drive of the limit plate 4. 6 approaches and contacts the second touch sensor 17 to be energized. During this process, the first slide plate 8 drives the second slide plate 9 and the vertical slide plate 10 to move toward the direction of the fixed plate 14. The buffer spring 15 provides a buffer force for sliding, which further weakens the impact force of the first touch sensor 16 and the second touch sensor 17 contacting each other, thereby ensuring the durable buffering purpose of the reverse light switch structure and extending its service life. In addition, when the user shifts the reverse gear to other gears, the trigger slide column 2 releases the contact and is driven by the reset spring 18 to reset the switch structure.
[0023] By utilizing the first sealing ring 3 and the second sealing ring 20 that are sealed at the trigger slide column 2 and the wiring plug 19, the main housing 1 forms a closed structure, which not only prevents foreign matter from entering the main housing 1 during the sliding process when the trigger slide column 2 is pushed in the reverse gear, but also prevents the transmission from contaminating the contacts through the gap at the wiring plug 19, thereby accelerating carbonization. This improves the dustproof sealing effect of the reverse light switch structure and extends its service life.
[0024] Furthermore, a front sleeve abutment plate 12 is fixedly sleeved on the outer surface of the vertical slide plate 10 that is in contact with the first slide plate 8, and a rear sleeve abutment plate 13 of the same size is fixedly sleeved on the outer surface of the other side of the vertical slide plate 10. The front sleeve abutment plate 12 and the rear sleeve abutment plate 13 are limited and abutted on both sides of the groove 11.
[0025] It is worth mentioning that the front sleeve abutment plate 12 and the rear sleeve abutment plate 13 prevent the vertical slide plate 10 from sliding off the slot 11, and have the purpose of limiting sliding. In addition, during the movement of the trigger switch structure, the front sleeve abutment plate 12 and the rear sleeve abutment plate 13 can both perform a resistance and limiting effect on the second slide plate 9 after it stops moving.
[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
