Description

Technical Field

[0001] This utility model relates to the field of automotive fender installation technology, specifically an automotive plastic fender installation and fixing structure. Background Technology

[0002] As an external body panel, the car fender needs to be matched with surrounding body panels such as the front door and hood, thus requiring high installation precision. Currently, many fender mounting structures use multiple sets of mounting holes and no positioning holes, relying on manual assembly and adjustment or tooling positioning to assemble them onto the vehicle body.

[0003] The existing car fenders do not have a buffer structure inside after installation. When the fender comes into contact with or collides with an object, it will be squeezed, causing the fender to contract and squeeze the mounting bolts. This can easily lead to the mounting bolts loosening during the squeezing process. Utility Model Content

[0013] (III) Beneficial Effects

[0014] 1. The automotive plastic fender mounting and fixing structure, by setting a first mounting plate, a second mounting plate, a damping sleeve, a damping rod, a tray, and a first buffer spring, can buffer the connection between the fender body and the car during use, preventing the fender body from becoming loose due to compression during contact or collision with external objects, thereby ensuring the stability of the mounting and fixing structure.

[0015] 2. This automotive plastic fender mounting and fixing structure, through the setting of a pre-tightening connecting plate, a positioning plate, and a second positioning hole, enables the mounting and fixing structure to pre-tighten the fender body during use, so that it can play a supporting role, thereby pre-hanging the fender body on the vehicle body to facilitate subsequent installation. Furthermore, by fine-tuning the fender body, the accurate position of the fender can be ensured, preventing the fender body from exceeding the standard gap between the installation and the vehicle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1-4 As shown, this utility model provides a car plastic fender mounting and fixing structure, including a fender body 1, a first mounting plate 2 connected to one side of the fender body 1, a second mounting plate 3 for connecting the car at the bottom of the first mounting plate 2, two damping sleeves 4 fixedly connected inside the second mounting plate 3, the damping sleeves 4 being filled with a damping medium, a damping rod 5 movably connected to the inner wall of the damping sleeve 4, the outer wall of the damping rod 5 being connected to the inner wall of the first mounting plate 2, and trays 6 fixedly connected to the outer walls of the damping sleeves 4 and the outer walls of the damping rods 5, with one end of each tray 6 connected to the top and bottom of the same first buffer spring 7.

[0024] Adjustable mounting holes 8 are provided inside the first mounting plate 2 and the second mounting plate 3. The second mounting plate 3 is located directly below the first mounting plate 2. A connector 9 is fixedly connected to one side of the second mounting plate 3. The second mounting plate 3 is connected to the fender body 1 through the connector 9. The adjustable mounting holes 8 facilitate the adjustment of the position of the fender body 1 and the car installation, ensuring the installation requirements of the fender body 1 are met.

[0025] Two mounting brackets 10 are provided at the bottom of the fender body 1. The mounting bracket 10 has a connection hole 11 for connecting to the car. A support plate 12 is fixedly connected to one side of the mounting bracket 10. A buffer telescopic rod 13 is fixedly connected to the top of the support plate 12. A second buffer spring 14 is provided inside the buffer telescopic rod 13. The top of the buffer telescopic rod 13 is connected to the bottom of the fender body 1. By setting the support plate 12, the buffer telescopic rod 13 and the second buffer spring 14, the connection between the mounting bracket 10 and the fender body 1 can be buffered to prevent the fender body 1 and the mounting bracket 10 from loosening after being pressed.

[0026] A pre-tightening connecting plate 15 is fixedly connected to one end of the fender body 1. A first positioning hole 16 is opened inside the pre-tightening connecting plate 15. A positioning plate 17 is fixedly connected to one side of the fender body 1. A number of second positioning holes 18 are opened at equal intervals inside the positioning plate 17. By setting the pre-tightening connecting plate 15, the positioning plate 17 and the second positioning holes 18, the installation and fixing structure can provide support by positioning and pre-tightening the fender body 1 during use, so as to pre-hang the fender body 1 on the vehicle body to facilitate subsequent installation. Furthermore, by fine-tuning the fender body 1, the position of the fender can be ensured to be accurate, preventing the gap between the fender body 1 and the car from exceeding the standard.

[0027] Working principle:

[0028] During installation, first align the pre-tightening connecting plate 15 with the corresponding mounting hole in the car. Then, use the first positioning hole 16 and bolts to initially position and pre-tighten the fender body 1. Since the pre-tightening connecting plate 15 is not fully fixed at this time, the fender body 1 can be rotated and finely adjusted by rotating the pre-tightening connecting plate 15. Align the positioning plate 17 and the second positioning hole 18 with the corresponding mounting hole in the car. Then, use bolts to fix the positioning plate 17 and the second positioning hole 18 with the mounting hole in the car. At this time, the positioning of the fender body 1 is completed. Then, use the adjustable mounting hole 8 to fix the first mounting plate 2 and the second mounting plate 3. Finally, fix the pre-tightening connecting plate 15.

[0029] When an external object is pressed against the fender body 1, the fender body 1 contracts under pressure and presses against the first mounting plate 2. The compression and contraction of the first mounting plate 2 causes the damping rod 5 to contract along the damping sleeve 4. At the same time, the damping rod 5 causes the tray 6 to press against the first buffer spring 7, causing the first damping spring to contract. When the external object is no longer pressed against the fender body 1, the first buffer spring 7 returns to its original position. The damping sleeve 4, through its internal damping medium, will obstruct the damping rod 5, thereby hindering the return rate of the first buffer spring 7, causing the first buffer spring 7 to slowly return to its original position, thus achieving the buffering effect.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
