[0002] In the structural design of an automobile, the automobile girder is a key component for bearing and transmitting load of the vehicle, and the performance thereof directly influences the safety and reliability of the automobile. With the rapid development of the automobile industry, the driving conditions of the vehicle are increasingly complex, and the automobile girder not only bears the weight of the vehicle itself and the load carried by the vehicle, but also needs to cope with lateral impact force from uneven road surface, collision and other forms.

[0003] At present, the support structure of the traditional automobile girder is relatively simple, and a single rigid connection mode is mostly adopted. When subjected to lateral impact force, the impact force will directly act on the main structure of the girder. Due to the lack of effective buffer and damping support structure, the impact force is difficult to be dispersed and relieved, which leads to deformation and even damage of the girder, greatly affecting the service life of the girder and the safety of the automobile driving.

[0004] Therefore, a structure design capable of effectively improving the stability and support strength of the automobile girder when subjected to impact is needed to solve the problems existing in the prior art. UTILITY MODEL CONTENTS

Due to the lack of effective buffer and damping support structure, the impact force is difficult to be dispersed and relieved, which leads to deformation and even damage of the girder, greatly affecting the service life of the girder and the safety of the automobile driving.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an automobile girder with high-strength support, comprising a girder, four reinforcing rods are welded between two girders, a fixed plate is installed on the two sides of the reinforcing rod through bolts respectively, a transverse pipe is welded on one side of the fixed plate;

[0011] Compared with prior art, the utility model has the beneficial effects that:

[0012] Each fixed plate is installed on both sides of each reinforcing rod by bolt, so that the transverse pipe is installed on the reinforcing rod, and finally the pad is adjusted to abut against the inner wall of the corresponding side of the girder. When the side of the girder is impacted, the pad will be driven to contract the movable rod to the inside of the transverse pipe.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figs. 1-3 The utility model provides the following technical scheme: a kind of automobile beam with high strength support, including beam 1, four reinforcing rods 2 are welded between two beams 1, reinforcing rod 2 two sides are respectively installed with a fixed plate 3 by bolt, one side of fixed plate 3 is welded with a transverse pipe 4;

[0021] The two ends of transverse pipe 4 are respectively movably sleeved with a movable rod 5, the end of each movable rod 5 away from transverse pipe 4 is respectively installed with a cushion block 6, one side of cushion block 6 is in contact with the inner wall of beam 1, a buffer block 7 is arranged below movable rod 5, and the bottom of buffer block 7 is fixedly installed on the surface of reinforcing rod 2.

[0022] Preferably: movable rod 5 is welded with a fixed piece 51 on the outer wall close to the connecting end of cushion block 6, and the bottom of fixed piece 51 is below the horizontal line on the surface of buffer block 7;

[0023] A limit disc 52 is welded on the end of movable rod 5 located in the inside of transverse pipe 4, a positioning piece 53 is movably sleeved on the outer wall of limit disc 52 on one side, the outer wall of positioning piece 53 is welded on the inner wall of transverse pipe 4, and two positioning pieces 53 are symmetrically arranged in the inside of transverse pipe 4.

[0024] When one of the movable rods 5 moves in the inside of transverse pipe 4, the movable rod 5 moves and pushes strong spring 41 to move to one side, so that the other end of strong spring 41 pushes the other set of limit disc 52 and movable rod 5 to move passively.

[0025] When the passively moved limit disc 52 moves to the positioning piece 53 opposite to it, it is blocked by the positioning piece 53, so that it cannot continue to move, and strong spring 41 is contracted.

[0026] Preferably, a strong spring 41 is installed inside the transverse pipe 4, and the two ends of the strong spring 41 are respectively connected with a limiting disc 52.

[0027] Preferably, the distance between the limiting disc 52 and the corresponding positioning sheet 53 is the same as the distance between the fixed sheet 51 and the buffer block 7.

[0028] In actual use, each fixed plate 3 is precisely aligned and installed on both sides of each reinforcing rod 2. Through the fastening effect of the bolts, the fixed plate 3 and the reinforcing rod 2 are stably connected, and then the transverse pipe 4 is also firmly installed on the reinforcing rod 2.

[0029] Then, according to the actual size and structural characteristics of the girder 1, a suitable cushion block 6 is selected and installed to ensure that it can be tightly abutted on the inner wall of the corresponding side of the girder 1.

[0030] In use, when the side of the girder 1 is subjected to impact force, this external force will be quickly transmitted to the cushion block 6 abutting on the inner wall of the girder 1. After being stressed, the cushion block 6 will drive the movable rod 5 connected thereto to shrink into the interior of the transverse pipe 4. In the moving process, the movable rod 5 will drive the fixed sheet 51 to move close to the buffer block 7. The buffer block 7 is made of high-elasticity and high-strength material and has good buffering performance. When the fixed sheet 51 is extruded with the buffer block 7, the buffer block 7 will absorb and offset part of the impact force transmitted by the movable rod 5 through its elastic deformation, effectively reducing the direct effect of the impact force on the girder 1.

[0031] At the same time, the movable rod 5 will also extrude the strong spring 41 installed in the transverse pipe 4 when it moves inside the transverse pipe 4. The strong spring 41 has a high elastic coefficient and good recovery performance. When extruded, it will store elastic potential energy by compression, convert part of the kinetic energy of the movable rod 5 into elastic potential energy, and thus offset part of the impact force of the movable rod 5.

[0032] In the whole process, the buffer block 7 and the strong spring 41 cooperate and act together to form a double buffering mechanism. This structural design can disperse and absorb the impact force on the girder 1, greatly improving the stability of the girder 1 when subjected to impact. Through the elastic deformation of the buffer block 7 and the compression of the strong spring 41, the damage degree of the impact force on the structure of the girder 1 is effectively reduced, thereby achieving the effect of significantly improving the support strength of the girder 1 and ensuring the normal use and structural safety of the girder 1 in complex stress environment.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
