Description

Technical Field

[0001] The utility model relates to the field of spare tire installation, in particular to a spare tire installation structure for a non-load-bearing vehicle body. Background Art

[0002] As an essential part of a car, tires play a very important role in the normal operation of the car. Once a problem occurs with the tire during driving, the entire car will be paralyzed. For this reason, spare tires are generally installed on cars to prevent the tire problem from affecting the driving process of the car during driving. For a non-load-bearing body, the spare tire is usually installed below the frame at the rear of the car and connected to the frame through a spare tire bracket and a lifter. However, since the existing spare tire is generally connected to the frame through the wheel core, the frame will be continuously subjected to the force of the feedback road surface transmitted through the suspension during driving, so that the spare tire is simplified to a cantilever structure with the wheel center point as the fixed point and the tire as the force point. Therefore, for a non-load-bearing body car, the spare tire bracket is a vulnerable part. However, most of the existing spare tire brackets are directly welded to the frame, which is prone to breakage. When repairing, the frame is usually replaced, and the repair cost is high. For this reason, there is also a solution to fix the spare tire bracket to the frame by bolts, but this spare tire bracket structure is relatively complex, the cost is high, and the disassembly and assembly are relatively complicated. Summary of the invention

[0003] In view of this, the utility model proposes a spare tire installation structure for a non-load-bearing vehicle body.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The spare tire installation structure for a non-load-bearing vehicle body described in the utility model comprises a spare tire installation frame and a spare tire lifter, wherein the spare tire installation frame comprises a spare tire cross beam and a limit bracket, wherein the spare tire cross beam is a groove-shaped structure, and the width of the spare tire cross beam gradually decreases from the middle to the two ends, and each end of the spare tire cross beam has an installation flange matched with a longitudinal beam, and each of the installation flanges is fixedly connected to the corresponding longitudinal beam by bolts;

[0006] The middle part of the spare tire cross beam is concave downward to form a mounting groove, the middle part of the bottom wall of the mounting groove is provided with a through hole matching the spare tire lifter, and the upper hole edge of the through hole is provided with a circle of edge guard, and the edge guard and the upper hole of the through hole are connected along an arc transition; the upper opening of the shell of the spare tire lifter is arranged, and a pair of outer flanges matching the bottom wall are integrally formed at the upper opening of the shell, and the outer flanges are fixed to the bottom wall by bolts; the height of the side wall of the spare tire cross beam gradually decreases from the middle to both sides, so that the shell is located inside the spare tire cross beam;

[0007] The limiting bracket is arranged below the spare tire cross beam along the longitudinal direction of the vehicle body, with the middle portion thereof being concave downward, and the concave portion of the limiting bracket is welded to the spare tire cross beam close to the mounting groove.

[0008] The beneficial effects are as follows: the width of the spare tire crossbeam of the utility model decreases from the middle to the two ends, which can not only ensure the strength at the middle position, further ensure the installation reliability of the spare tire lifter, but also save materials and reduce costs; the side wall of the spare tire crossbeam is high in the middle and low at the two ends, which can effectively protect the spare tire lifter and save materials. The spare tire crossbeam of the utility model has high strength and is detachably connected to the longitudinal beam, and the spare tire lifter is detachably connected to the spare tire crossbeam, which is convenient for replacing the spare tire crossbeam and the spare tire mounting frame, has little impact on the frame, and reduces maintenance costs.

[0009] The middle part of the limiting bracket of the utility model is concave, which effectively ensures the welding effect between the limiting bracket and the spare tire cross beam; the limiting bracket is close to the installation groove (and then close to the spare tire lifter), which can limit the spare tire.

[0010] Preferably, the cross section of the limit bracket is a U-shaped structure, and the top of the side wall of the limit bracket has a welding flange, and the limit bracket is welded to the spare tire beam through the welding flange. The beneficial effect is that the limit bracket of the utility model is connected to the spare tire beam through the welding flange, which is convenient for welding; in addition, the limit bracket adopts a U-shaped cross section, and then forms a channel with the spare tire beam, which can resist certain deformation.
