Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a bumper performance testing device. Background Art

[0002] Bumpers, usually referring to car bumpers, are protective devices installed at the front and rear ends of a vehicle. Their main functions are aesthetics, as well as absorbing the impact of a collision, protecting the vehicle structure and passenger safety, as well as pedestrian safety. The design and performance of the bumper are critical to the overall safety of the vehicle, so it is necessary to pass a series of rigorous tests to ensure that it meets safety standards and performance requirements, including impact resistance tests.

[0003] A car may encounter impacts from various directions while driving, but the current bumper impact resistance test usually performs impact from the middle of the front side of the bumper.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2 As shown, the present invention provides a bumper performance testing device, which is mainly tested by launching an impact ball 8 to impact the bumper installed on the mounting plate 4.

[0022] The bumper performance testing device comprises a bottom plate 1, a fixing plate 2 is provided on one side of the top of the bottom plate 1, and a supporting plate 3 is provided on the other side of the top of the bottom plate 1;

[0023] The side of the fixing plate 2 close to the supporting plate 3 is set as an arc surface, and a mounting plate 4 for mounting a bumper is provided on the outer side of the arc surface, and a plurality of mounting blocks 5 are fixedly mounted on the outer side of the mounting plate 4. The mounting plate 4 is set as an arc plate, and the inner side wall of the mounting plate 4 is in contact with one side of the arc surface on the fixing plate 2, so that the inner wall of the mounting plate 4 is in contact with the arc surface and rotated in the up-down direction to adjust the inclination angle of the mounting plate 4 relative to the horizontal plane;

[0024] A box body 6 with a top opening is connected to the top of the support plate 3 for sliding left and right, so that the box body 6 can slide left and right on the top of the support plate 3 to adjust its position relative to the mounting plate 4. A launching port 7 is opened on the side of the box body 6 close to the fixed plate 2, and an impact ball 8 is arranged inside the box body 6. The impact ball 8 is launched from the launching port 7 toward the mounting plate 4 under the action of external force.

[0025] The current bumper impact test usually carries out impact from the middle of the front side of the bumper. The test impact direction is relatively single, which is inconsistent with the actual situation and cannot well reflect the impact resistance during actual driving. Therefore, it is necessary to develop a test device with multiple test impact directions.

[0026] This embodiment is provided with a rotatable mounting plate 4 to mount and fix the bumper to be tested, so that the bumper to be tested can be tilted upward or downward relative to the horizontal plane. At the same time, an impact ball 8 is provided whose launching position can be moved left and right. The launching position of the impact ball 8 can be changed to simulate the impacts from various directions encountered by the bumper in actual use, thereby expanding the test direction of the impact force and making the impact resistance test result closer to the actual situation.

[0027] As a preferred embodiment of the present embodiment, in order to better launch the impact ball 8, a card plate 9 is slidably connected to the inside of the box body 6 along the length direction of the box body 6, and a spring 10 is fixedly connected between the card plate 9 and the inner wall of the box body 6. The impact ball 8 is arranged on the side of the card plate 9 away from the spring 10. When the card plate 9 is subjected to external force, it squeezes the spring 10 so that the spring 10 has a rebound force. The impact ball 8 is launched from the launch port 7 toward the mounting plate 4 under the action of the rebound force of the spring 10.

[0028] In actual use, 1. Fix the bumper to be tested and the mounting block 5 by screws, so that the bumper to be tested is fixed on the mounting plate 4, and wait for testing;

[0029] 2. Set the box 6 in the middle of the top of the support plate 3, move the card plate 9 to the side of the spring 10, and squeeze the spring 10. At this time, the spring 10 has a rebound force, and then place the impact ball 8 against the card plate 9, release the force that fixes the card plate 9, and due to the rebound force of the spring 10, the impact ball 8 is launched toward the bumper and hits the bumper, completing the impact force test;

[0030] 3. In order to be closer to the actual situation, impacts are carried out in multiple directions. Without adjusting the fixed position of the bumper, the box body 6 is slid left and right on the support plate 3, and the position of the box body 6 relative to the bumper is continuously adjusted. Each time the box body 6 moves a position, the impact force test is carried out once by the impact ball 8, so that the impact ball 8 continuously hits different positions on the same horizontal line of the bumper;

[0031] 4. The inner wall of the mounting plate 4 is rotated in the up-and-down direction to fit the arc surface to adjust the inclination angle of the mounting plate 4 relative to the horizontal plane, thereby adjusting the inclination angle of the bumper to be tested relative to the horizontal plane, that is, changing the height position at which the impact ball 8 hits the bumper. Each time the mounting plate 4 is rotated once, that is, the bumper inclination angle is adjusted once, the above step 3 is repeated, so that the impact ball 8 continuously hits different positions on the same horizontal line of the bumper, and test data of different impact directions can be obtained.

[0032] In order to realize the rotation of the mounting plate 4, further, as Figure 3As shown, a central axis 11 is fixedly installed on both sides of the fixing plate 2, and a bracket 12 is rotatably connected to the outer surface of the central axis 11. The end of the bracket 12 is fixedly connected to the side of the mounting plate 4. The bracket 12 rotates around the central axis 11 under the action of external force, so that the inner wall of the mounting plate 4 rotates in the up and down directions in accordance with the arc surface.

[0033] A plurality of fixing holes 13 are provided on both sides of the fixing plate 2 , and the bracket 12 is fixed to different fixing holes 13 by screws to adjust the rotation angle of the bracket 12 .

[0034] The mounting plate 4 is fixed by the bracket 12 , and at the same time, the bracket 12 is rotated so that the bracket 12 is fixed to different fixing holes 13 to adjust the rotation angle of the mounting plate 4 .

[0035] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
