Description

Mounting structure of spare tire for car

The present invention relates to a mounting structure of a spare tire for an automobile, and more specifically, to improve the structure of the underbody of the vehicle on which the spare tire is mounted and the bolt, which is a coupling means, by using a general tool for mounting and detaching the spare tire. The present invention relates to a mounting structure of a spare tire for a vehicle that can be performed quickly and has a cost reduction effect by using general bolts.

In general, a tire in a motor vehicle generally refers to a wheel composed of a wheel and a tire. The tire supports and shares the entire weight of the vehicle, and includes braking and driving torque, shock on the road, centrifugal force during turning, and automobile. It serves to withstand the lateral force generated when the slope is inclined. On the other hand, tires that play such roles may cause punctures due to friction with the road surface and poor road conditions as the total driving time of the car increases, and in preparation for this, spare tires are usually installed in the trunk or the body of the car. .

The mounting structure of the tire is illustrated in FIGS. 1A and 1B, and the mounting structure of the conventional vehicle tire will be described with reference to the following.

First, as shown in FIG. 1A, a coupling portion 20c 'having a trapezoidal cross section is formed in the center of the trunk of the vehicle so that the spare tire 10' may be mounted, and the coupling portion 20c 'is formed. The spare tire 10 'is located on the top. Of course, predetermined through holes 10a and 20a 'are formed in the center of the coupling portion 20c' and the spare tire 10 ', and are located in a straight line with each other, and the weld nut is disposed on the bottom of the coupling portion 20c'. 35 'is joined to the bottom face of the engaging part 20c' by welding. Meanwhile, a bolt 30 'is coupled to the weld nut 35' of the underbody 20 'through a through hole 10a' formed at the center of the spare tire 10 ', which is a spare tire 10'. ) Is to support and fix the under body 20 '.

Looking at the structure of the bolt 30 'in more detail as shown in Fig. 1B is formed on the top of the head 35' of the hexahedral shape so that a special tool can be coupled to the top and fixed to the head 35 ' It consists of a bolt (30 ') formed with a thread at the bottom. In addition, an umbrella-shaped bracket 36 'is fitted at the joint of the head 35' and the bolt 30 ', and a jaw 37' is formed at the central portion of the bolt 30 'so that the spare tire 10 ') Is located inside. The jaw 37 'is formed to prevent the bracket 36' from being detached from the bolt 30 '.

A conventional method for mounting a spare tire 10 'for a vehicle having such a structure is that of the weld nut 35' and the spare tire 10 'of the coupling portion 20c' formed on the underbody 20 'in the trunk. The spare tire 10 'is positioned on the coupling portion 20c' in a state where the through holes 10a 'are aligned with each other. Then, the bolt 30 'is inserted into the inlet of the weld nut 35' mounted on the bottom of the spare tire 10 'and the engaging portion 20c', and the head of the bolt 30 'as a special tool ( 35 '), the bolt 30' is rotated and inserted into the weld nut 35 'of the coupling portion 20c' so that the spare tire 10 'can be firmly coupled to the underbody 20'. It is planning. In this case, when the spare tire 10 ′ is separated from the under body 20 ′, the head 35 ′ of the bolt 30 ′ may be reversely rotated.

However, the conventional mounting structure of the spare tire for automobiles is not compatible because all of the bolt heads, brackets, etc., which are components of the bolt, are formed in a completely different shape from the head and washer of a general bolt, and thus, a special tool must be manufactured separately. If there is a need to prepare a special tool was difficult to install and remove the problem.

The present invention has been made to solve the conventional problems as described above, by improving the structure of the bolt and the body and the coupling means of the underbody of the vehicle to which the spare tire is mounted to quickly perform the mounting and removal of the spare tire with a common tool. It is possible to provide a mounting structure for a spare tire for automobiles that can reduce costs by using general bolts.
