Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a collision avoidance testing device for new energy vehicles. Background Technology
[0002] The crash beam is a key device for absorbing energy during a vehicle collision. It typically consists of a main beam, an energy-absorbing box, and a mounting plate connected to the vehicle body. The main beam and energy-absorbing box can effectively absorb impact energy during low-speed collisions, thereby reducing damage to the longitudinal beams of the vehicle body and achieving a protective function. However, since crash beams are usually irregular plate-shaped structures, their fixing effect is poor, which may cause shaking during the inspection process, thereby reducing inspection efficiency.
[0003] Therefore, a utility model is proposed for a collision avoidance detection device for new energy vehicles. Utility Model Content
[0004] The purpose of this invention is to provide a collision avoidance detection device for new energy vehicles to solve the above-mentioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A collision avoidance detection device for new energy vehicles includes a detection platform. Two sets of limiting clamps are fixedly connected to the top of the detection platform, and a collision avoidance beam is engaged with the opposite sides of the two sets of limiting clamps. A detection frame is fixedly connected to the middle section of the top of the detection platform. A detection hammer is fixedly connected inside the detection frame. The detection hammer is located at the middle section of the top of the collision avoidance beam. A measuring device is installed inside the detection frame, and the side of the measuring device is located at the top of the collision avoidance beam.
[0007] The outer wall of the testing frame is provided with a height mark, which is located on the side of the measuring device.
[0008] Furthermore, the limiting fixture includes a fixture base plate, the interior of which is provided with a sliding groove, and a limiting block is slidably fitted inside the sliding groove. A second column is fixedly connected to the top of the limiting block, and a connecting plate is movably fitted to the outer wall of the second column. A movable groove is provided inside the connecting plate, and a threaded rod is slidably fitted to the inner wall of the movable groove. The bottom end of the threaded rod is fixedly connected to the fixture base plate, and a sleeve block is threadedly connected to the outer wall of the threaded rod. A push block is fixedly connected to one side of the sleeve block, and a handle is fixedly connected to the other side of the sleeve block. A second push block is fixedly connected to the top of the connecting plate, and the outer wall of the second push block fits against the outer wall of the sleeve block.
[0009] Furthermore, a column is fixedly connected to the top of the fixture base plate, one end of a spring is fixedly connected to the outer wall of the column, and the other end of the spring is fixedly connected to the outer wall of the limit block.
[0010] Furthermore, a spring is movably sleeved on the outer wall of the threaded rod, one end of the spring is fixedly connected to a clamp base plate, and the other end of the spring is in contact with the bottom end of the connecting plate.
[0011] Furthermore, two sets of hinge blocks are fixedly connected to the top of the fixture base plate, and movable stop blocks are hinged to the top of the hinge blocks.
[0012] Furthermore, a baffle is fixedly connected to the top of the fixture base plate, and the baffle is located on the opposite side of the movable stop block and the spring.
[0013] Furthermore, the measuring device includes a motor, the outer wall of which is fixedly connected to the surface of the detection frame, the output end of which is fixedly connected to a threaded rod II, the outer wall of which is threadedly connected to a measuring plate, and the measuring plate is movably sleeved with a column III, the two ends of which are fixedly connected to the outer wall of the detection frame.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. A fixture adaptable to curved crash beams is installed. Traditional fixtures may not perfectly accommodate complex curved crash beams, leading to swaying or positional shifts during testing. A fixture adaptable to curved crash beams is specifically designed for different curves and geometries, providing a tight hold to the beam, reducing swaying and maintaining stability. This stability is crucial for accurately measuring deformation and damage after a collision, ensuring the reliability of test results. In crash testing, accurate fixation and measurement ensure that the assessment results reflect the true crash performance, thus helping to develop safer crash protection designs. This not only improves vehicle safety but also provides consumers with more reliable safety assurance.
[0016] 2. Measuring the front and rear height of the crash beam after a collision can effectively assess its deformation and thus determine the extent of damage. Ensuring the energy absorption performance and collision protection effect of the crash beam is crucial. After a collision, the change in height directly reflects the crash beam's ability to absorb and disperse energy during the collision. If the difference in front and rear height exceeds the expected range, it may mean that the crash beam has failed to effectively absorb the impact force, thereby affecting the overall safety performance. Accurate height measurement not only helps to detect the structural integrity of the crash beam, but also provides key data for future design improvements, thereby enhancing the vehicle's collision protection performance.

[0023] 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.
[0024] Please see Figures 1 to 4 As shown, the collision detection device for new energy vehicles provided by this utility model includes a detection platform 1. Two sets of limiting clamps are fixedly connected to the top of the detection platform 1, and a collision beam 5 is clamped on the opposite side of the two sets of limiting clamps. A detection frame 3 is fixedly connected to the middle section of the top of the detection platform 1. A detection hammer 4 is fixedly connected inside the detection frame 3. The detection hammer 4 is located in the middle section of the top of the collision beam 5. A measuring device is provided inside the detection frame 3, and the side of the measuring device is located at the top of the collision beam 5.
[0025] The outer wall of the testing frame 3 is provided with a height mark 24, which is located on the side of the measuring device.
[0026] Two sets of limiting clamps are used to accommodate anti-collision beams 5 with different curvatures. The anti-collision beam 5 is fixed at the top of the testing table 1 below the testing hammer 4. The testing hammer 4 performs a hammering test on the anti-collision beam 5. Before and after the hammering test, the height of the anti-collision beam 5 is measured by the measuring device and the height is measured by the height mark 24. The height difference is observed to determine whether the product quality meets the requirements.
[0027] The limiting fixture includes a fixture base plate 2. The fixture base plate 2 has a sliding groove inside, and a limiting block 19 is slidably sleeved inside the sliding groove. A second column 18 is fixedly connected to the top of the limiting block 19. A connecting plate 9 is movably sleeved on the outer wall of the second column 18. A movable groove is opened inside the connecting plate 9. A threaded rod 11 is slidably sleeved on the inner wall of the movable groove. The bottom end of the threaded rod 11 is fixedly connected to the fixture base plate 2. A sleeve block 12 is threadedly connected to the outer wall of the threaded rod 11. A push block 13 is fixedly connected to one side of the sleeve block 12. A handle 10 is fixedly connected to the other side of the sleeve block 12. A second push block 14 is fixedly connected to the top of the connecting plate 9. The outer wall of the second push block 14 fits against the outer wall of the sleeve block 12.
[0028] A column 16 is fixedly connected to the top of the fixture base plate 2. One end of a spring 17 is fixedly connected to the outer wall of the column 16. The other end of the spring 17 is fixedly connected to the outer wall of the limit block 19.
[0029] A spring 15 is movably sleeved on the outer wall of the threaded rod 11. One end of the spring 15 is fixedly connected to the clamp base plate 2, and the other end of the spring 15 is in contact with the bottom end of the connecting plate 9.
[0030] Two sets of hinge blocks 6 are fixedly connected to the top of the fixture base plate 2, and a movable stop block 7 is hinged to the top of the hinge block 6.
[0031] A baffle 8 is fixedly connected to the top of the fixture base plate 2, and the baffle 8 is located on the opposite side of the movable stop block 7 and the spring 15.
[0032] When installing the anti-collision beam 5, first place the anti-collision beam 5 on the upper end of the two sets of movable blocks 7, then turn the handle 10, thereby driving the sleeve block 12 to rotate on the outer wall of the threaded rod 11. When the push block 13 faces the anti-collision beam 5, it is affected by the elastic potential energy of the spring 17, pulling the column 18 to move inward, further driving the limiting block 19 to slide inside the clamp base plate 2, and at the same time pulling the connecting plate 9 to move inward synchronously, so that one end of the connecting plate 9 is located at the top of the anti-collision beam 5 to clamp the anti-collision beam 5. When the connecting plate 9 applies a certain pressure to the anti-collision beam 5, the hinge block 6 rotates to drive the movable block 12 to move inward. The abutment 7 fits tightly against the bottom end of the anti-collision beam 5, thus adapting to the curve of the anti-collision beam 5 and preventing shaking during testing. Conversely, when replacement is needed, the handle 10 is turned again, causing the sleeve block 12 to drive the push block 13 to rotate synchronously around the threaded rod 11. When the protruding end of the push block 13 contacts the push block 14, it pushes the push block 14 and drives the connecting plate 9 to move outward synchronously, further causing the column 18 to move outward. At this time, under the influence of the elastic potential energy of the spring 15, the bottom end of the connecting plate 9 is disengaged from the surface of the anti-collision beam 5, thus allowing easy replacement of the next set of anti-collision beams 5.
[0033] The baffle 8 is set to prevent the anti-collision beam 5 from extending to both ends during the testing process, which would compress the spring 15 and cause damage. It also limits the anti-collision beam 5 to further ensure the stability of the measurement results.
[0034] The measuring device includes a motor 20, the outer wall of which is fixedly connected to the surface of the detection frame 3, the output end of the motor 20 is fixedly connected to a threaded rod 21, the outer wall of the threaded rod 21 is threadedly connected to a measuring plate 23, the inside of the measuring plate 23 is movably sleeved with a column 22, and the two ends of the column 22 are fixedly connected to the outer wall of the detection frame 3.
[0035] Before and after the impact inspection, the starter motor 20 drives the threaded rod 21 to rotate inside the inspection frame 3, which in turn drives the measuring plate 23 to move up and down inside the inspection frame 3. The protruding end of the measuring plate 23 is in contact with the top surface of the anti-collision beam 5, thereby measuring its height. After two measurements, the measurement data are compared to analyze whether the quality of the anti-collision beam 5 meets the required requirements.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
