Description

Technical Field

[0001] The utility model relates to the field of automobile parts, and more specifically to a structure which is convenient for adjusting the clearance surface difference of automobile fenders. Background Art

[0002] The fender is the outer panel of the car body that covers the wheels. It is named because the shape and position of this part on the old car body resemble bird wings. According to the installation position, it is divided into front fenders and rear fenders. The front fender is installed at the front wheel, and the maximum limit space when the front wheel rotates and bounces must be guaranteed. Therefore, the designer will use the "wheel bounce diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size;

[0003] The body fender is normally hard-connected to the body by bolts. The existing mounting structure cannot adjust the mounting points. When adjusting the clearance surface difference between the fender and surrounding components, it is necessary to loosen the bolts and then make adjustments, which is troublesome. The bolts will be repeatedly loosened and tightened, and the paint surface will be easily damaged, affecting the corrosion protection of the fender. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a structure for facilitating the adjustment of the clearance surface difference of automobile fenders, which can solve the problems of repeatedly loosening and tightening the bolts and easily damaging the paint surface and affecting the anti-corrosion of the fenders.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, a structure is provided for facilitating adjustment of the surface difference of the gap of a car fender, comprising a fender having a door snap-fitted connection on the left side, the door having a vehicle body rotatably connected on the left side, the front surface connection of the fender being threadedly connected via an installation adjustment bolt, the front end of the installation adjustment bolt being integrally formed with a bolt adjustment end, and the outer side wall of the installation adjustment bolt being fixedly connected to a fixed end face of the fender.

[0006] Furthermore, an outer side wall of the mounting adjustment bolt is threadedly connected with a mounting nut located on the left side of the fender fixing end surface.

[0007] The beneficial effects of the structure for adjusting the gap surface difference of automobile fenders of the utility model are as follows:

[0008] When installing the adjusting bolt, the upper thread on the fender fixing end surface is a reverse thread, and the lower thread on the fender fixing end surface is a positive thread; rotating the positive thread clockwise will shorten the corresponding distance for tightening, and rotating it counterclockwise will lengthen the corresponding distance for loosening; rotating the reverse thread clockwise will lengthen the corresponding distance for loosening, and rotating it counterclockwise will shorten the corresponding distance for tightening; by installing the positive and negative threads on the adjusting bolt, the linkage of the adjusting bolt can be avoided when tightening the mounting nut.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0017] According to one aspect of the present invention, Figure 1-5 As shown, a structure for adjusting the clearance surface difference of automobile fenders is provided, including a car door 2 being snap-connected to the left side of the fender 1, and a car body 3 being rotatably connected to the left side of the car door 2; a front surface connection of the fender 1 is threadedly connected by an installation adjustment bolt 4, a bolt adjustment end 5 is integrally formed at the front end of the installation adjustment bolt 4, and an outer side wall of the installation adjustment bolt 4 is fixedly connected to a fender fixed end face 6; an installation nut 7 is threadedly connected to the outer side wall of the installation adjustment bolt 4, and is located on the left side of the fender fixed end face 6;

[0018] The upper thread of the fender fixing end face of the installation adjusting bolt is a reverse thread, and the lower part of the fender fixing end face is a positive thread. The positive thread is rotated clockwise to tighten, and the corresponding distance is shortened at this time. Counterclockwise rotation is to loosen, and the corresponding distance is lengthened at this time. The reverse thread is rotated clockwise to loosen, and the corresponding distance is lengthened at this time. Counterclockwise rotation is to tighten, and the corresponding distance is shortened at this time. The positive and negative threads on the installation adjusting bolt can avoid the linkage of the installation adjusting bolt when tightening the installation nut;

[0019] The installing adjusting bolt 4 is connected to the vehicle body 3, and the installing adjusting end 5 is rotated clockwise to fix the installing adjusting bolt to the corresponding position of the vehicle body; the fender 1 is connected to the installing adjusting bolt 4 by rotating the installing nut 6 counterclockwise. After the fender 1 and the installing adjusting bolt 4 are installed, the fitting clearance between the fender and the surrounding parts is adjusted through the fender mounting hole; the fitting surface difference with the surrounding parts is adjusted by the installing adjusting bolt adjusting end 5; if the fender protrudes from the vehicle door, the installing adjusting bolt adjusting end 5 is rotated clockwise to shorten the distance between the fender 1 and the vehicle body 3. If the fender is lower than the vehicle door, the installing adjusting bolt adjusting end 5 is rotated counterclockwise to expand the distance between the fender 1 and the vehicle body 3.

[0020] The working principle of this device is:

[0021] The upper thread of the fender fixing end face of the installation adjusting bolt is a reverse thread, and the lower part of the fender fixing end face is a positive thread. The positive thread is rotated clockwise to tighten (the corresponding distance is shortened), and counterclockwise to loosen (the corresponding distance is lengthened). The reverse thread is rotated clockwise to loosen (the corresponding distance is lengthened), and counterclockwise to tighten (the corresponding distance is shortened). The positive and negative threads on the installation adjusting bolt can avoid the linkage of the installation adjusting bolt when tightening the installation nut;

[0022] The installing adjusting bolt 4 is connected to the vehicle body 3, and the installing adjusting end 5 is rotated clockwise to fix the installing adjusting bolt to the corresponding position of the vehicle body; the fender 1 is connected to the installing adjusting bolt 4 by rotating the installing nut 6 counterclockwise. After the fender 1 and the installing adjusting bolt 4 are installed, the fitting clearance between the fender and the surrounding parts is adjusted through the fender mounting hole; the fitting surface difference with the surrounding parts is adjusted by the installing adjusting bolt adjusting end 5; if the fender protrudes from the vehicle door, the installing adjusting bolt adjusting end 5 is rotated clockwise to shorten the distance between the fender 1 and the vehicle body 3. If the fender is lower than the vehicle door, the installing adjusting bolt adjusting end 5 is rotated counterclockwise to expand the distance between the fender 1 and the vehicle body 3.

[0023] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
