Description

Technical Field

[0001] The utility model relates to an automobile bumper with a buffer function, belonging to the technical field of automobile accessories. Background Art

[0002] Bumpers are installed at the front and rear ends of cars. They not only serve a decorative purpose, but more importantly, they absorb and mitigate external impacts, protecting the car body and occupants. Bumpers provide safety protection, decorative features, and improve the vehicle's aerodynamics. From a safety perspective, they act as a buffer in low-speed collisions, protecting the front and rear bodies. They also provide some protection for pedestrians in accidents. From an aesthetic point of view, they are decorative and have become an important component in the car's appearance. They also play a role in aerodynamics.

[0003] A Chinese patent (publication number: CN 216101970 U) discloses a car bumper with a buffering function, comprising a mounting base and a support plate. The mounting base has a fixing screw hole on its front surface, and a positioning telescopic rod is fixedly connected to the front side wall of the mounting base at a central position. The positioning telescopic rod is fixedly connected to a buffer plate shell at one end away from the mounting base. This car bumper with a buffering function effectively reduces the instantaneous impact force during a collision through secondary step-by-step buffering, thereby improving the protection effect. In particular, it reduces the damage caused by collisions when a car collides with pedestrians or non-motor vehicles passing through intersections. If the vehicle accidentally collides with a flower bed or other hard objects while reversing, it can stop immediately after hearing a sound. Generally, fixed bumpers will be squeezed and deformed, but the buffer plate shell will retract when hit, thereby reducing the damage caused by the collision, improving the protection effect of the buffer plate shell, and providing the vehicle with a certain anti-collision buffering distance.

[0004] The above patent improves the protection effect and reduces the damage caused by collision, but it is not convenient for quick disassembly and replacement of the car bumper. After the collision, the car bumper will often be deformed. At this time, the entire car bumper needs to be replaced, which increases the cost of replacement and causes waste of resources. Moreover, after the collision, if the accident is serious, not only the car bumper will be damaged, but even the vehicle will also suffer certain damage. There is a lack of a device to protect the vehicle.

[0005] Therefore, a car bumper with a buffering function is proposed. Utility Model Content

The outer surface of the second plug rod 409 is wound with a limiting spring 410.

[0030] By setting up the quick-release mechanism 4, the anti-collision plate 2 can be pressed toward the back side to move the slot 405 toward the back side, thereby driving the first socket 406 and the first insertion rod 407 to move toward the back side. At this time, the first insertion rod 407 will slide to the back side of the sliding block 403, and then the anti-collision plate 2 is moved as a whole to the front side, so that the first insertion rod 407 can slide over the outer surface of the sliding block 403, thereby disengaging from the sliding block 403 and the semicircular plate 404, completing the quick disassembly of the anti-collision plate 2.

[0031] Example 2

[0032] like Figure 2 As shown, in one embodiment, a protective device 5 is provided on the back side of the bumper body 1, and the protective device 5 includes a protective airbag 501. There are two protective airbags 501, which are respectively provided on the left and right sides of the back side of the bumper body 1. Gas cylinders 502 are provided on the outer sides of the protective airbags 501, and an air supply pipe is provided between the protective airbags 501 and the gas cylinders 502.

[0033] By providing the protective device 5, at the moment of collision, due to the buffering effect of the quick-release mechanism 4, the force will be applied to the gas cylinder 502, and at the same time, the gas in the gas cylinder 502 will quickly fill the protective airbag 501, causing the protective airbag 501 to expand, thereby providing a certain degree of protection for the vehicle and preventing the deformed bumper from damaging the vehicle itself.

[0034] Example 3

[0035] like Figure 5As shown, in one embodiment, the buffer device 3 includes a first connecting plate 301, the first connecting plate 301 is fixedly connected to the front side of the bumper body 1, the front side of the first connecting plate 301 is fixedly connected to a first buffer block 302, the front side of the first connecting plate 301 and the first buffer block 302 are fixedly connected to the first connecting blocks 303, the first connecting blocks 303 located on the left and right sides are a group, each group of first connecting blocks 303 is connected by a rotating shaft, the front side of the first buffer block 302 is provided with two extrusion plates 305, a buffer airbag 306 is provided between the two extrusion plates 305, the front of the extrusion plate 305 on the front side is provided with a buffer airbag 306, and the front of the extrusion plate 305 on the front side is provided with a buffer airbag 306. A second buffer block 307 is provided on the side, and the inner sides of the first buffer block 302 and the second buffer block 307 pass through the inner surface of the extrusion plate 305 and fit the outer surface of the buffer airbag 306.

The back side of the second connecting plate 308 and the four sides of the second buffer block 307 are fixedly connected with second connecting blocks 309 of the same size as the first connecting block 303. The second connecting blocks 309 located on the left and right sides are a group, and each group of second connecting blocks 309 is connected by a rotating shaft. A swing rod 310 is provided on the inner side of each first connecting block 303 and the second connecting block 309.

[0036] When the anti-collision plate 2 is hit by an external impact, the buffer device 3 and the quick release mechanism 4 will move to the back side, and at the same time, the second connecting plate 308 and the second buffer block 307 will be driven to squeeze the buffer airbag 306, and the buffer airbag 306 will play a role in buffering the impact.

[0037] The utility model is in operation: first, under normal use, after the anti-collision plate 2 is hit by an external impact, it will drive the buffer device 3 and the quick-release mechanism 4 to move to the back side, and at the same time drive the second connecting plate 308 and the second buffer block 307 to squeeze the buffer airbag 306, and the buffer airbag 306 has a buffering effect on the impact, and drives the swing rod 310 to swing through the second connecting plate 308, so that the slider 304 slides outward at the same time, and the slider 304 pulls the drawstring 6 during the movement, so that the drawstring 6 pulls the pull ring of the gas cylinder 502, and the gas inside the gas cylinder 502 will quickly enter the protective gas cylinder 502 through the air supply pipe. The interior of the bag 501 causes the protective airbag 501 to expand, preventing the anti-collision plate 2 from deforming after being hit and causing damage to the vehicle. When the anti-collision plate 2 is damaged and needs to be replaced, the anti-collision plate 2 can be pressed toward the back side to move the slot 405 toward the back side, thereby driving the first hole 406 and the first insertion rod 407 to move toward the back side. At this time, the first insertion rod 407 will slide to the back side of the sliding block 403, and then the anti-collision plate 2 is moved to the front side as a whole, so that the first insertion rod 407 can slide over the outer surface of the sliding block 403, thereby disengaging from the sliding block 403 and the semicircular plate 404, completing the quick disassembly of the anti-collision plate 2.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
