Description

Technical Field

[0001] This utility model relates to the field of bumper technology, specifically a bumper with a positioning structure. Background Technology

[0002] The bumper is an important component of a car body, primarily functioning to absorb and mitigate external impacts, protecting the front and rear of the vehicle. It covers a large area at the front and rear of the car, encompassing the front and rear sections of the body structure. It generally consists of an outer panel, cushioning material, and crossbeams, and is often made of highly elastic materials such as plastics and resins. These materials not only have good energy absorption properties but also allow for easy replacement after a collision.

[0003] To protect the driver, when a bumper is needed for assistance, the bumper body is first placed close to the front of the car. Then, the bumper body is aligned with the front of the car using a mounting base, and finally, the bumper is secured with clips and screws, thus protecting the front of the vehicle. However, during bumper assembly, the positioning holes used for limiting the position have low precision, and there may be some deviation in the position of the positioning holes at the front of the vehicle. This makes it difficult to control the gap between the bumper and the vehicle body, making it easy for the gap between the bumper and the vehicle body to exceed the tolerance, thereby affecting the use of the bumper.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5This utility model provides a technical solution: a bumper with a positioning structure, including a bumper body 1, a mounting base 2, and an auxiliary mechanism 3. The auxiliary mechanism 3 is provided on one side of the inner wall of the bumper body 1. The auxiliary mechanism 3 includes a support seat 301, a threaded post 302, a fixing seat 303, a threaded rod 304, a limiting seat 305, a positioning pin 306, a fixing post 307, a fixing rod 308, a first spring 309, a support post 310, a support rod 311, and a second spring 312. The mounting base 2 has support seats 301 connected to both sides of its middle section, and the support seats 301 are internally... A threaded post 302 is rotatably connected, and a fixed seat 303 is threadedly connected to the middle of the outer wall of the threaded post 302. A threaded rod 304 is connected inside the fixed seat 303, and a limiting seat 305 is threadedly connected to the middle of the outer wall of the threaded rod 304. A locating pin 306 is welded to the middle of the outer wall of the limiting seat 305. A movable cavity is opened inside the mounting base 2, and the fixed seat 303 extends into it. The fixed seat 303 has a "T"-shaped structure. A movable groove is opened inside the fixed seat 303, and the limiting seat 305 extends into it. The limiting seat 305 has a "T"-shaped structure. The bumper body A fixing post 307 is welded to the middle of the outer wall, and a fixing rod 308 is slidably connected inside the fixing post 307. A first spring 309 is sleeved on the middle of the outer wall of the fixing rod 308. One side of the outer wall of the fixing rod 308 is connected to the mounting base 2. The fixing posts 307 are symmetrically distributed about the vertical center line of the bumper body 1. The two sides of the outer wall of the first spring 309 are connected to the fixing posts 307 and the mounting base 2 respectively. The fixing posts 307, the fixing rod 308 and the first spring 309 form an elastic telescopic mechanism. A support post is welded to the side of the mounting base 2 near the support seat 301. 310, and a support rod 311 is slidably connected inside the support column 310, and a second spring 312 is sleeved in the middle of the outer wall of the support rod 311. One side of the outer wall of the support rod 311 is connected to the inner wall of the bumper body 1; the two sides of the outer wall of the second spring 312 are respectively connected to the bumper body 1 and the support column 310. The support column 310, the support rod 311 and the second spring 312 form an elastic telescopic mechanism. The support column 310 is distributed in a figure-eight shape; the limiting seat 305 and the fixed seat 303 are slidably connected, and the fixed seat 303 and the mounting base 2 are slidably connected.

[0021] In practical implementation, when the bumper needs to be installed at the front of the car, because the fixing seat 303 is connected to the threaded rod 304, firstly, rotating the threaded rod 304 generates a pushing force on the limiting seat 305, causing the limiting seat 305 to move downward along the fixing seat 303. Since the limiting seat 305 is connected to the positioning pin 306, the movement of the limiting seat 305 will drive the positioning pin 306 to move together, thereby vertically moving the positioning pin 306 so that its height corresponds to the preset positioning hole height. Then, rotating the threaded post 302 inside the support seat 301... The movement will generate a thrust on the fixed seat 303, causing the fixed seat 303 to drive the limiting seat 305 to move horizontally until the positioning pin 306 moves horizontally to the designated position. Then, the horizontal position of the positioning pin 306 corresponds to the preset positioning hole, preventing the deviation between the positioning pin 306 and the positioning hole from being too large, which would result in an excessive gap between the bumper body 1 and the vehicle body. After that, the positioning pin 306 is inserted into the preset positioning hole to limit the bumper body 1, preventing the bumper body 1 from moving arbitrarily and affecting the installation, thus making it easier for the staff to position and install the bumper.

[0022] When a car collides with another object due to an accident, if the middle of the bumper body 1 collides first, the fixed post 307 and the fixed rod 308 are slidably connected. At this time, the fixed post 307 will slide along the fixed rod 308. Then, the movement of the fixed post 307 will compress the first spring 309, causing it to deform. Afterwards, the elastic force generated by the first spring 309 returning to its original position will offset the impact force generated by the collision. If the sides of the bumper body 1 collide with another object first, the support rod 311 will slide along the support rod 311, thereby compressing the second spring 312, causing it to deform. Afterwards, the elastic force generated by the second spring 312 returning to its original position will offset the impact force generated by the collision. Thus, when a car collides with another object due to an accident, it can buffer the impact generated by the collision in the middle and on both sides, thereby protecting the driver and reducing injury. Therefore, when using the bumper, it plays a role in facilitating positioning and installation and providing buffer protection.

[0023] In summary, when using this type of bumper with a positioning structure, the bumper body 1 is first brought close to the front of the car. Then, the bumper body 1 is connected to the front of the car through the mounting base 2, and the bumper is fixed by clips and screws. This protects the front of the car body. This is existing technology and will not be elaborated on here. The vertical height and horizontal position of the positioning pin 306 are adjusted by the auxiliary mechanism 3 to prevent excessive deviation between the positioning pin 306 and the positioning hole, which would result in excessive gap between the bumper body 1 and the car body. This facilitates the positioning and installation of the bumper by the staff. In the event of a collision between the car and other objects due to an accident, the bumper can buffer the impact of the collision in the middle and on both sides, thereby protecting the driver and reducing injury. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
