Abstract

The utility model relates to a spare tyre hole (1), including foundation pit (11) and spare tyre hole plane (12), wherein crossbeam (2) have been arranged on spare tyre hole plane (12), crossbeam (2) are hugged closely at two tip departments on foundation pit (11).

Description

A kind of spare tyre hole

Technical field

This utility model is related to a kind of spare tyre hole, and specifically, this utility model is related to a kind of spare tyre hole with crossbeam.

Background technology

The region for car load holding vehicles spare tyre and related tool cheated by automobile rear floor spare tyre.Fig. 1 shows traditional Design form cheated by spare tyre, and the molding in spare tyre hole needs to place the heavy of spare tyre by stretched for flat mild steel plate one Hole.Because spare tyre hole is relatively deep, after mould drawing, vehicle body mild steel plate has larger reduction.

At present, reduce discharging increasingly increasing of demand with car load loss of weight, spare tyre hole region plate is larger, and weight loss effect is obvious, Therefore, one of its thinning important means also becoming vehicle body loss of weight.But the simple thickness reducing spare tyre hole steel plate is easy to draw Play a lot of problems：Spare tyre mount point intensity deficiency is also easy to produce panel beating cracking；Spare tyre hole region modalities variation produces NVH vibration and makes an uproar Sound；Reduce the safety in rear impact simultaneously.

Utility model content

Therefore, the purpose of this utility model is to provide a kind of spare tyre hole, and it is applied to various vehicles.

In order to solve this purpose, this utility model provides a kind of spare tyre hole, cheats plane including crater wall and spare tyre, wherein, Described spare tyre hole plane on arrange crossbeam, described crossbeam two ends be close in described crater wall that is to say, that Install a reinforcement additional in the plane of spare tyre hole, for strengthening the intensity in spare tyre hole, improved mode, reduced when spare tyre hole is reversed Cracking risk, and strengthen the safety of rear impact.

Alternatively, section in the plane in the direction of elongate perpendicular to described crossbeam for the described crossbeam is circle, that is, horizontal The cross section of beam is circle.

Alternatively, section in the plane on the longitudinal direction perpendicular to described crossbeam for the described crossbeam is triangle, that is, The cross section of crossbeam is triangle.

Alternatively, rectangular cross-section in the plane on the longitudinal direction perpendicular to described crossbeam for the described crossbeam, that is, horizontal The cross section of beam is rectangle.

Alternatively, the scope of the width in described section is 30 to 70mm, and the scope of the height in described section is 10 to 50mm.

The specific cross sectional shape in section and dimensional parameters carry out adaptability design according to different designs situation.

Alternatively, described crossbeam is welded to connect with spare tyre hole at two ends.

Alternatively, described crossbeam cheats Adherents junction at two ends with spare tyre.

Alternatively, described crossbeam is connected with spare tyre hole clamping at two ends.

Benefit of the present utility model is：By optimized Structure Design, both reached car load loss of weight purpose, improved whole again The fatigue endurance of car, vibrating noise and security performance, structure is simple.

Brief description

Referring to the drawings, disclosure of the present utility model will be easier to understand.Skilled addressee readily understands that It is：These accompanying drawings are intended solely for illustrative purposes, and are not intended to protection domain of the present utility model is construed as limiting.In figure：

Fig. 1 shows the view in the spare tyre hole according to prior art,

Fig. 2 shows the view by spare tyre described in the utility model hole.

Fig. 3 shows the sectional view cheated along section A by spare tyre described in the utility model.

Specific embodiment

For helping those skilled in the art can definitely understand the theme that this utility model claims, with reference to Accompanying drawing describes specific embodiment of the present utility model in detail.

Fig. 1 shows spare tyre hole of the prior art, and the molding in spare tyre hole needs will be stretched for a flat mild steel plate One heavy hole that can place spare tyre.Because spare tyre hole is relatively deep, after mould drawing, vehicle body mild steel plate has larger subtracting Thin rate.

Fig. 2 shows and uses new spare tyre to cheat 1 according to this, cheats plane 12 including crater wall 11 and spare tyre, wherein, described Crossbeam 2 is arranged, described crossbeam 2 is close in described crater wall 11 two ends in the plane 12 of spare tyre hole.In the example shown, institute State rectangular cross-section in the plane on the longitudinal direction perpendicular to described crossbeam for the crossbeam 2.

Fig. 3 shows described crossbeam 2 along the sectional view of the section A in Fig. 2, and the scope of the width w in described section is 30 To 70mm, the scope of the height h in described section is 10 to 50mm.

Described crossbeam two ends can with spare tyre hole be welded to connect, Adherents junction or clamping are connected.

Although being illustrated in detail in and described specific embodiment of the utility model so that principle of the present utility model to be described, It will be appreciated that, this utility model can be with embodied in other without deviating from such principle.
