[0025] For descriptive purposes, the present disclosure can use spatial or relative terms, such as "below," "lower," "above," "upper," "on," "over," "higher," and "side" (e.g., as in "sidewall") to describe the relative relationship between one element and another element as illustrated in the figures. The spatial or relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture, for example. That is, if the device in the figures is turned over, elements described as "below" or "under" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatial or relative descriptors used herein interpreted accordingly.

[0026] As shown in Figures 1-3 The automobile bottom plate cross beam assembly with good damping effect of the present disclosure can include assembly component 1, pull-out damping mechanism 2, and outer damping mechanism 3.

[0027] As shown in Figure 2 In the present disclosure, the assembly component 1 includes longitudinal beams 11, front cross beams 12, rear cross beams 13, front bumpers 14, rear bumpers 15, engine front suspension cross beams 16, engine rear suspension cross beams 17, cab rear suspension cross beams 18, and rear steel plate support cross beams 19. The longitudinal beams 11 are provided in two, and the two longitudinal beams 11 are arranged side by side. The front cross beams 12 are fixedly arranged at the left ends of the two longitudinal beams 11. The rear cross beams 13 are fixedly arranged at the right ends of the two longitudinal beams 11. The front bumpers 14 are fixedly arranged outside the front cross beams 12. The rear bumpers 15 are fixedly arranged outside the rear cross beams 13. The engine front suspension cross beams 16, the engine rear suspension cross beams 17, the cab rear suspension cross beams 18, and the rear steel plate support cross beams 19 are sequentially fixedly arranged between the two longitudinal beams 11 from left to right.

[0028] As shown in Figure 3As shown, in a preferred embodiment, four groups of the withdrawable shock-absorbing mechanisms 2 are evenly arranged on the outside of the assembly component 1, and the withdrawable shock-absorbing mechanism 2 includes a mounting stud 21, an L-shaped plate 22, an avoidance channel 23, a fixing nut 24, a withdrawal handle 25, a shock-absorbing spring 26 and a first elastic plate 27, wherein the mounting stud 21 is provided in plurality and is all fixedly arranged on the outside of the longitudinal beam 11, the L-shaped plate 22 is slidably fitted to the outside and bottom of the longitudinal beam 11, the avoidance channel 23 is opened on the outside of the L-shaped plate 22, the mounting stud 21 is located on the inner side of the adjacent avoidance channel 23, the fixing nut 24 is threadedly connected to the outside of the adjacent mounting stud 21, the withdrawal handle 25 is fixedly arranged on the middle part of the outer side of the L-shaped plate 22, the shock-absorbing spring 26 is fixedly connected to the bottom of the L-shaped plate 22, and the first elastic plate 27 is fitted to the bottom end of the shock-absorbing spring 26 and is rotatably connected to the L-shaped plate 22 through a pin.

[0029] Therefore, when it is necessary to disassemble the shock absorber composed of the shock absorbing spring 26 and the first elastic plate 27, the operator can rotate the two fixing nuts 24 to disengage the two fixing nuts 24 from the outside of the corresponding mounting studs 21, and then hold the withdrawal handle 25 and pull it outward. At this time, the withdrawal handle 25 drives the shock absorber composed of the shock absorbing spring 26 and the first elastic plate 27 to move outward between the longitudinal beam 11 and the second elastic plate 31 through the L-shaped plate 22, thereby completing the disassembly. Compared with existing products of the same type, the disassembly of the shock absorber can be completed more conveniently, reducing the difficulty of operation, reducing the physical expenditure of the operator, and being more convenient in actual use.

[0030] like Figure 3 As shown, in the present disclosure, the external shock absorbing mechanism 3 also includes a second elastic plate 31 and a connecting seat 32, wherein the second elastic plate 31 is attached to the bottom of the adjacent first elastic plate 27, and two connecting seats 32 are provided. The two connecting seats 32 are rotatably connected to the two ends of the second elastic plate 31 through a pin shaft, and the connecting seat 32 is slidably nested at the bottom of the longitudinal beam 11.

[0031] Therefore, when the wheel is impacted during driving, the second elastic plate 31 is deformed by the force, thereby pushing the connecting seat 32 to slide at the bottom of the longitudinal beam 11, thereby partially eliminating the impact force. The remaining impact force acts on the first elastic plate 27 and the shock-absorbing spring 26 in turn. The first elastic plate 27 and the shock-absorbing spring 26 are deformed in turn, thereby absorbing the remaining impact force to achieve multiple shock absorption.

[0032] It should also be noted that the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0033] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. Based on the above disclosure, other changes or modifications can be made by those skilled in the art, and these changes or modifications are still within the scope of the present disclosure.
