Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-3 The present invention provides the following technical solution:

[0028] A vehicle bumper performance testing device, including:

[0029] Mounting platform 1, with a moving groove 9 at the upper end;

[0030] Two lead screws 17 are rotatably connected between the inner walls of the two sides of the movable groove 9, and the two lead screws 17 are fixedly connected to each other.

[0031] Motor 14 is fixedly connected to one end of mounting platform 1, and its output end is fixedly connected to one of the lead screws 17.

[0032] Two sets of fixing mechanisms are provided, each consisting of a mounting shell 10, a pressing plate 13, and a crescent-shaped block. The mounting shell 10 is fixedly connected to the upper end of one of the lead screws 17, the pressing plate 13 is located on the upper side of the mounting shell 10, and the crescent-shaped block is fixedly connected to the lower end of the pressing plate 13. The crescent-shaped block has an arc-shaped surface with a lower surface smaller than a semicircle. The upper inner surface of the mounting shell 10 is a mounting groove, which, through the crescent-shaped block and the mounting shell, forms a pressing space to limit the movement of the bumper. The shape of the mounting groove can be customized according to the bumper structure.

[0033] The hydraulic mechanism is located on the upper side of the mounting platform 1. The hydraulic mechanism consists of a hydraulic cylinder 6, a mounting plate 7, abutment block 8, a top plate 5, and multiple mounting rods 4. The multiple mounting rods 4 are all fixedly connected to the upper end of the mounting platform 1. The top plate 5 is fixedly connected to the upper end of the multiple mounting rods 4. The hydraulic cylinder 6 is fixedly connected to the upper end of the top plate 5. The mounting plate 7 is fixedly connected to the piston rod of the hydraulic cylinder 6. The abutment block 8 is fixedly connected to the lower end of the mounting plate 7.

[0034] In a specific embodiment of this utility model, when the bumper needs to be tested, the bumper is placed inside two mounting shells 10. Then, the bumper is fixed inside the mounting shells 10 by the downward movement of the crescent block and the pressing plate 13. After that, the hydraulic cylinder 6 is activated to move its piston rod downward, which in turn moves the mounting plate 7 and the abutment block 8 downward. The abutment block 8 abuts against the bumper, causing it to bend. The performance of the bumper is judged by the degree of bending. When it is necessary to test bumpers of different lengths, the motor 14 is activated to drive the lead screw 17 to rotate. Then, the two lead screw nuts 20 will move towards each other or away from each other, which facilitates the testing and inspection of bumpers of different sizes and improves the versatility of this device. It should be noted that the specific model of motor 14 used can be selected by those skilled in the art, and the above-mentioned motor 14 and other related technologies are all prior art, which will not be elaborated in this solution.

[0035] Please refer to the details. Figure 2 The lower end of the mounting platform 1 is fixedly connected to two support legs 2, and the near ends of the two support legs 2 are fixedly connected to reinforcing rods 3. The upper end of the mounting shell 10 is fixedly connected to multiple springs 15, and the multiple springs 15 are all fixedly connected to the lower end of the pressing plate 13.

[0036] Preferably, a plurality of telescopic rods 16 are fixedly connected to the upper end of the mounting housing 10, which can prevent the spring 15 from bending and deforming.

[0037] In this embodiment: multiple support legs 2 and multiple reinforcing rods 3 can be used to mount the platform 1 and multiple components, and multiple springs 15 can automatically pull the pressing plate 13, making the bumper locking and unlocking simpler.

[0038] Please refer to the details. Figure 2 A handle 11 is fixedly connected to the upper end of the pressing plate 13, and an anti-disengagement sleeve 12 is fixedly connected to the circumferential surface of the handle 11. A limit groove 18 is opened on the lower inner wall of the moving groove 9, and a limit block 19 is fixedly connected to the lower end of each of the two lead screw nuts 20.

[0039] In this embodiment: the pressing plate 13 can be easily pulled by the handle 11 and the anti-disengagement sleeve 12. When the lead screw nut 20 moves, the limiting block 19 can slide in the limiting groove 18, thereby improving the horizontal movement stability of the lead screw nut 20.

[0040] The working principle and usage process of this utility model are as follows: When the bumper needs to be tested, the bumper is placed inside the two mounting shells 10. Then, the bumper is fixed inside the mounting shells 10 by the downward movement of the crescent block and the pressing plate 13. After that, the hydraulic cylinder 6 is activated to move its piston rod downward, which in turn moves the mounting plate 7 and the abutment block 8 downward. The abutment block 8 abuts against the bumper, causing it to bend. The performance of the bumper is judged by the degree of bending. When it is necessary to test bumpers of different lengths, the motor 14 is activated to drive the lead screw 17 to rotate. Then, the two lead screw nuts 20 will move towards each other or away from each other, which facilitates the testing and inspection of bumpers of different sizes.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
