[0002] An automobile bumper test jig is a test device used to detect the performance and durability of an automobile bumper. It is usually used to simulate different collision conditions to test the ability of the bumper to withstand impacts in a static state.

[0003] In an existing Chinese published patent (authorization publication number: CN218875227U), an automobile bumper inspection tooling is mentioned. It can adjust the height of the support plate through a lifting structure to adjust the height of the clamping structure. After placing the two ends of the bumper into the two clamping structures respectively, control the clamping structure to clamp the two ends of the bumper to complete the fixation of the bumper, thus solving the problem that in the existing bumper detection jig, the heights of the first column and the second column are fixed, and the height position of the bumper cannot be adjusted when the bumper is fixed on the jig.

[0004] When conducting performance tests on automobile bumpers, most of the existing methods fix the bumper on the installation base through jigs for convenient performance tests. However, during the test process, in order to test the performance of the bumper, relatively large impact forces are often applied. If the local stress of the bumper is too large, it may cause the material to break or shatter, and then generate fragments scattered on the installation base. After the test is completed, it may be necessary for the staff to manually clean the installation base with a brush, which increases the work intensity of the staff and is rather inconvenient.

[0031] The following will Figures 1-5 further elaborate on the present utility model in conjunction with the attached drawings.

[0032] An embodiment of the present utility model discloses an automobile bumper test fixture.

[0033] Referring to Figure 1 and Figure 2 , an automobile bumper test fixture includes a test bench 1, columns 2 fixedly connected to both sides of the top of the test bench 1, a clamping device 3 arranged on the mutually approaching sides of the two columns 2, a control panel 4 fixedly connected to the outside of the test bench 1, a collection mechanism arranged on the top of the test bench 1, and an adjustment mechanism arranged inside the columns 2.

[0034] When testing the bumper, first place the bumper in the two clamping devices 3. The clamping device 3 consists of clamping blocks, lead screws, etc. By rotating the lead screw, the clamping blocks clamp and fix the bumper, thus facilitating the staff to test and detect the bumper. The collection mechanism can collect the waste generated during the test, reducing the inconvenience of manual cleaning by the staff. The adjustment mechanism can adjust the height position of the bumper, improving the flexibility of the bumper test.

[0035] Referring to Figure 1 , Figure 3 and Figure 4 , the collection mechanism includes a protective plate 5 fixedly connected to the top of the test bench 1. A feeding hole 6 is opened on the top of the test bench 1. The inner wall of the feeding hole 6 is in a funnel shape. A collection box 7 is movably arranged on the inner bottom wall of the test bench 1. The top of the collection box 7 is in an open shape. The opening of the collection box 7 is adapted to the feeding hole 6. Four corners of the bottom of the collection box 7 are provided with rollers. A handle 8 is fixedly connected to the outside of the collection box 7.

[0036] Among them, engaging columns 9 are fixedly connected to both sides of the inner bottom wall of the test bench 1 in a left-right symmetrical manner. Engaging plates 10 are fixedly connected to both sides of the collection box 7 in a left-right symmetrical manner. A moving groove 11 is formed inside the engaging column 9, and the moving groove 11 is adapted to the engaging plate 10. A vertical groove 12 is formed inside the engaging column 9. A spring 13 is fixedly connected to the inner top wall of the vertical groove 12. The bottom end of the spring 13 is fixedly connected to a moving plate 14. There is an engaging block 15 at the bottom of the moving plate 14. An engaging groove 16 is formed at the top of the engaging plate 10. Both the engaging block 15 and the engaging block 15 are hemispherical, and the engaging block 15 is engaged with the engaging groove 16.

[0037] In addition, sliding grooves are formed on both sides of the vertical groove 12. Sliding blocks are fixedly connected to both sides of the moving plate 14. The sliding blocks are adapted to the sliding grooves, and the sliding blocks are slidably connected to the sliding grooves.

[0038] Moreover, a guiding seat 17 is fixedly connected to the side of the engaging column 9 close to the collection box 7. Guiding blocks 18 are fixedly connected to both sides of the collection box 7. The guiding seat 17 is arranged in a concave shape, and the guiding block 18 is slidably arranged with the guiding seat 17.

[0039] When waste is generated, the fragmented waste will fall on the top of the test bench 1. Through the material discharge hole 6 formed on the top of the test bench 1, the fragmented waste will fall into the material discharge hole 6. Then, due to the adaptation of the opening of the collection box 7 inside the test bench 1 to the material discharge hole 6, the waste will fall into the collection box 7 for collection. When a certain amount is collected, the staff can pull the handle 8 to take out the collection box 7, so as to process the fragmented waste inside, enabling the staff to not need to frequently clean the test bench 1 during the test process, being able to focus on the test operation itself, thereby reducing the labor intensity of the staff;

[0040] When collecting the waste, first place the collection box 7 inside the test bench 1. During the movement of the collection box 7, the engaging plate 10 will be driven to move. The moving engaging plate 10 will enter the moving groove 11. At this time, the engaging plate 10 will touch the engaging block 15. Since the engaging block 15 is hemispherical, after being squeezed, the engaging block 15 moves upward. The upward movement of the engaging block 15 will drive the moving plate 14 upward. The upward movement of the moving plate 14 will compress the spring 13 to generate elastic potential energy. When the engaging groove 16 moves to the position of the engaging block 15, the elastic potential energy of the spring 13 explodes, causing the engaging block 15 to be engaged with the engaging groove 16, thereby limiting the position of the collection box 7 and improving the stability of the collection box 7 during operation. Since both the engaging block 15 and the engaging groove 16 are hemispherical, when taking out, under the action of the arc surface of the engaging groove 16, the engaging block 15 moves upward to disengage from the engaging groove 16, thereby taking out the collection box 7;

[0041] When the collection box 7 is moving, the guiding seat 17 and the guiding block 18 provide a limiting function for the collection box 7, enabling the collection box 7 to move to a suitable position.

[0042] When the moving plate 14 is moving, the slider and the sliding groove provide a guiding function for the moving plate 14, so that the moving plate 14 maintains a correct movement track when moving.

[0043] Referring to Figure 1 、 Figure 2 and Figure 5 and , the adjusting mechanism includes a rotating motor 19 fixedly connected to the top of the column 2. The output shaft of the rotating motor 19 penetrates through the column 2 and is fixedly connected with a threaded rod 20. The output shaft of the rotating motor 19 is rotatably connected with the column 2. A connecting block 21 is threadedly connected to the outside of the threaded rod 20, and the connecting block 21 is fixedly connected with the clamping device 3.

[0044] Among them, an auxiliary rod 22 is fixedly connected to the inner bottom wall of the column 2. The top end of the auxiliary rod 22 penetrates through the connecting block 21 and is fixedly connected with the inner top wall of the column 2. The auxiliary rod 22 is slidably connected with the connecting block 21.

[0045] Before clamping the bumper, the rotating motor 19 is started through the control panel 4. The rotating motor 19 rotates to drive the threaded rod 20 to rotate. Since the connecting plate is threadedly connected to the threaded rod 20, the connecting plate moves up and down. And the connecting plate is fixedly connected with the clamping device 3, so as to adjust the height of the clamping device 3, improve the flexibility and adaptability of the clamping operation, and thus expand the applicable range of the equipment;

[0046] When the connecting plate is moving, the auxiliary rod 22 provides an additional support point for the connecting plate, so that the connecting plate moves smoothly.

[0047] Working principle: Place the bumper in the two clamping devices 3. The clamping device 3 is composed of clamping blocks, lead screws, etc. By rotating the lead screw, the clamping blocks clamp and fix the bumper, so as to facilitate the staff to conduct test detection on the bumper. The debris and waste will fall on the top of the test bench 1. Through the blanking hole 6 opened on the top of the test bench 1, the debris and waste will fall into the blanking hole 6. Then, through the opening of the collection box 7 inside the test bench 1 being adapted to the blanking hole 6, the waste will fall into the collection box 7 and be collected. When a certain amount is collected, the staff can pull the handle 8 to take out the collection box 7, so as to process the debris and waste inside.

[0048] The position of the collection box 7 is limited by the snap fit of the snap block 15 and the snap groove 16, which improves the stability of the collection box 7 during operation. The slider and the sliding groove provide a guiding function for the moving plate 14, so that the moving plate 14 maintains a correct movement track when moving. The rotating motor 19 rotates to drive the threaded rod 20 to rotate. Since the connecting plate is threadedly connected to the threaded rod 20, the connecting plate moves up and down. And the connecting plate is fixedly connected with the clamping device 3, so as to flexibly adjust the height of the clamping device 3.
