Description

A car spare tire mounting structure

technical field

The utility model belongs to the technical field of automobiles and relates to an automobile spare tire mounting structure.

Background technique

This year, with the improvement of the economic level of the Chinese people and the increasingly convenient transportation, more and more people travel by car. Therefore, it is required to increase the trunk volume of the vehicle as much as possible in the design process to meet the increasing life and travel needs of people. The space required by the necessary items; thus, a part of the spare tire installation structure is derived due to the increase in the volume of the trunk. This structure brings certain risks to the design of the installation structure of the spare tire of the body. The strength of the vehicle is sufficient to meet the floor solder joints falling off and the rear floor tearing caused by driving on bumpy roads, the vibration and noise caused by the lack of local rigidity of the spare tire installation structure when the vehicle is running at high speed, and the excessive reinforcement structure increases the weight of the vehicle body posed a series of problems.

For example, a patent for a spare tire bracket [authorized announcement number: CN202011433U] disclosed in the Chinese patent literature includes a crossbeam connecting the frame girder and a raised strip for hanging the spare tire. A flat plate with a large contact surface with the hub. The utility model has the advantages of simplicity, convenience, low cost, easy disassembly and the like.

Even so, the stability of the above-mentioned patent still needs to be improved to adapt to the bumpy road surface. When the vehicle bumps, the structure is prone to noise. When the bracket brings potential safety hazards to the whole vehicle, it reduces the driving comfort.

In the above installation structure for a spare tire of an automobile, the reinforcement plate is located above the installation plate and in the middle of the rear floor.

The action force of the spare tire on the installation structure is from top to bottom. The reinforcement plate is located above the installation plate and the rear floor, which can effectively prevent the deformation of the installation plate and the rear floor due to the gravity of the spare tire. The installation plate and the reinforcement plate are located on the rear The middle part of the floor makes the overall structure symmetrical and the force is even, which makes the installation structure more resistant to deformation.

In the above installation structure for a spare tire of an automobile, the installation plate is welded and fixedly connected to the rear floor.

In the above installation structure for a spare tire of an automobile, the reinforcing plate is welded and fixedly connected to the rear floor.

Both the mounting plate and the reinforcement plate are welded and fixed to the rear bottom plate, which makes the structure stronger and stronger.

In the above-mentioned installation structure for a spare tire of an automobile, the reinforcing plate has a plurality of stamped protrusions, and is concave in the middle, and two mounting holes for installing the lifting mechanism are provided in the concave portion. The concavo-convex structure can simply and effectively improve the anti-deformation ability of the reinforcing plate.

In the above-mentioned mounting structure for a spare tire of a car, the mounting plate is provided with four mounting holes for mounting the elevating mechanism, and the elevating mechanism is fixed by cooperating with bolts and six mounting holes. The six mounting holes and the six bolts can effectively and firmly fix the lifting mechanism under the mounting plate and the reinforcing plate.

Compared with the prior art, the utility model has strong integrity, and the installation of the spare tire is made more stable through the reasonable collocation and connection between the boards, so that the safety and comfort of the whole vehicle are greatly improved.
