Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an adjustable automobile bumper. Background Art

[0002] A bumper is a safety device installed at the front and rear of a vehicle. Its primary function is to absorb and mitigate external impact forces, protecting the front and rear of the vehicle from collision damage. These devices are typically made of plastic or metal, with a certain degree of elasticity and impact resistance. In the event of a collision, the bumper disperses the impact force, mitigating damage to occupants and other components within the vehicle.

[0003] A search revealed a Chinese patent application with publication number CN214028536U, which discloses a vehicle bumper with adjustable ground clearance. The bumper comprises a bumper body, a fixing plate disposed on the inner side of the bumper body, a first slot formed in the middle of the fixing plate, a first slider welded to the middle of the inner side surface of the bumper body, the surface of the first slider inserted into the first slot, the fixing plate connected to the first slider via a lifting mechanism, and second sliders welded to the left and right sides of the bumper body, each of which has a second slot formed on the left and right sides of the fixing plate. The utility model adjusts the bumper's ground clearance by rotating a threaded rod to cause the first slider to move up and down, improving the device's convenience. When the second slider needs to be fixed to the fixing plate, the second slider and the fixing plate are locked by rotating a bolt, preventing the bumper from shaking and improving the device's practicality. Although the bumper height of this patent is adjustable, a fixing plate is also provided on the back of the bumper body, and the fixing plate is fixedly connected to the frame, and the fixing plate overlaps with the bumper body to achieve the adjustment of its up and down position. Therefore, when the height of the bumper is adjusted, the height of the fixing plate is still inconvenient. Therefore, even if the bumper height of this patent is adjusted, its fixing plate will still rub the ground and cannot achieve the expected effect. Utility Model Content

[0025] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an adjustable automobile bumper of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1-4As shown, the utility model is an adjustable automobile guard bar, including a guard bar body 1 and a height adjustment mechanism, the height adjustment mechanism includes a mounting plate 2, the surface of the mounting plate 2 is respectively mounted with a first fixing seat 3 and a second fixing seat 8, a motor 4 is mounted on the first fixing seat 3, the shaft of the motor 4 is connected to a triangular plate 5, an L-shaped block 14 is connected between the triangular plate 5 and the second fixing seat 8 through a connecting rod mechanism, a fixing plate 13 is fixedly connected to the L-shaped block 14, the connecting rod mechanism includes a first connecting rod 6, a second connecting rod 7 and a third connecting rod 9, a first connecting rod 6 is connected to the first connecting rod 6, a second connecting rod 7 and a third connecting rod 9, One end is rotatably connected to the triangle plate 5 through a rotating shaft, and the other end is rotatably connected to the top side wall of the L-shaped block 14 through a rotating shaft. One end of the second connecting rod 7 is rotatably connected to the triangle plate 5 through a rotating shaft, and the other end is rotatably connected to the middle part of the third connecting rod 9 through a rotating shaft. One end of the third connecting rod 9 is rotatably connected to the second fixed seat 8 through a rotating shaft, and the other end is rotatably connected to the bottom of the L-shaped block 14 through a rotating shaft. The height adjustment mechanism is fixedly connected to the vehicle frame through the mounting plate 2. Due to the setting of the connecting rod mechanism, the height of the mounting plate 2 is higher than the height of the guard bar body 1. The triangle plate 5 includes a first connecting angle 10, a second connecting angle 11 and a third connecting angle 12. The first connecting angle 10 is fixedly connected to the shaft of the motor 4, and the shaft of the motor 4 is rotatably connected to the first fixed seat 3 through a bearing. The end of the first connecting rod 6 is rotatably connected to the second connecting angle 11 through a rotating shaft, and the end of the second connecting rod 7 is rotatably connected to the third connecting angle 12 through a rotating shaft. The second fixed seat 8 is located at the lower left of the first fixed seat 3. By starting the motor 4, the motor 4 drives the triangle plate 5 to rotate. At the first connecting rod 6, the second connecting rod 7 and the third connecting rod 8, the first connecting rod 6, the second connecting rod 7 and the third connecting rod 8 are rotated. With the cooperation between the connecting rods 9, the L-shaped block 14 can be driven to move up and down. Since the L-shaped block 14 is fixedly connected to the fixing plate 13, and the fixing plate 13 is fixedly connected to the guard bar body 1, the L-shaped block 14 drives the guard bar body 1 to move up and down, so that the height of the guard bar body 1 can be flexibly adjusted, that is, the distance between the guard bar and the ground can be adjusted. Therefore, when encountering bad road conditions and many potholes, the guard bar can be raised to make the guard bar higher from the ground, avoiding the situation where the guard bar rubs the ground, and effectively preventing damage to the guard bar.

[0027] The fixing plate 13 is fixedly connected to the back of the bumper body 1. Four rectangular fixing brackets 16 are provided on the back of the bumper body 1. The four corners of the fixing plate 13 are fixed to the fixing brackets 16 with screws. The cooperation between the fixing brackets 16 and the fixing plate 13 facilitates the removal and installation of the bumper body 1 from the height adjustment mechanism, greatly improving convenience. The back of the bumper body 1 is provided with a retaining structure for retaining the fixing plate 13. The retaining structure includes two upper and lower retaining plates 15, which are evenly fixed to the back of the bumper body 1. The spacing between the two retaining plates 15 matches the width of the fixing plate 13. The arrangement of the upper and lower retaining plates 15 allows the fixing plate 13 to be placed between the upper and lower retaining plates 15 during installation, limiting the fixing plate 13 and facilitating quick installation. The lower retaining plate 15 also provides auxiliary support for the fixing plate 13, further strengthening the structural strength.

[0028] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
