Description
Technical Field
[0001] This utility model relates to the field of automotive rear bumper beam strength measurement technology, specifically to an automotive rear bumper beam strength measurement device with a protective structure. Background Technology
[0002] The rear bumper beam is a metal bar installed at the rear of a vehicle. Its core function is to resist the impact of a rear collision and reduce the potential harm to the occupants by absorbing the collision energy. In order to ensure the impact force of the rear bumper beam and ensure the safety of the occupants, it is necessary to conduct strength tests on the rear bumper beam by simulating various possible collision scenarios. Currently, there are various strength measurement devices for rear bumper beams on the market, but there are still some shortcomings.
[0003] In practical applications, current automotive rear bumper beam strength measuring devices, based on existing solutions and actual production processes, often produce fragments during impact testing. These fragments scatter, posing a threat to the safety of testing personnel if not properly protected. Furthermore, the use of hydraulic cylinders in impact testing, without regular maintenance, significantly shortens their lifespan. Therefore, we propose a rear bumper beam strength measuring device with a protective structure to address these issues. Utility Model Content
[0004] The purpose of this utility model is to provide a vehicle rear bumper beam strength measuring device with a protective structure, in order to solve the problems mentioned above in the background art. Current vehicle rear bumper beam strength measuring devices, combined with existing solutions and actual production and processing, produce fragments when the rear bumper beam is subjected to impact testing. These fragments scatter, and without blocking the fragments, they pose a threat to the safety of the test personnel. At the same time, the use of hydraulic cylinders for impact testing, without long-term maintenance of the hydraulic cylinders, will greatly shorten their service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a strength measuring device for a car rear anti-collision beam with a protective structure, comprising:

[0028] 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.
[0029] Please see Figures 1-6 This utility model provides a technical solution:
[0030] To address the problems existing in the prior art, this embodiment provides the following technical solution: a vehicle rear anti-collision beam strength measuring device with a protective structure, comprising a support base 1; a protective structure, located on the outside of the mounting block 12, which can block debris generated by the impact of the vehicle rear anti-collision beam when the device is opened, effectively ensuring the personal safety of the test personnel; a shock-absorbing mechanism, located at the output end of the hydraulic cylinder 5, which can reduce the impact damage to the hydraulic cylinder 5 during a collision; and a maintenance mechanism, located on the outside of the output end of the hydraulic cylinder 5, which can periodically apply lubricating oil to the hydraulic cylinder 5, thereby extending the service life of the hydraulic cylinder 5.
[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the support base 1 is fixedly connected to the ground, which effectively ensures the stability of the support base 1. At the same time, mounting holes 2 are symmetrically and evenly spaced on the top of the support base 1. Bolts can be inserted into the mounting holes 2 to firmly fix the fixing plate 4 on the top of the support base 1. The position of the fixing plate 4 can be adjusted by opening multiple mounting holes 2 at equal intervals on the top of the inside of the support base 1.
[0032] A fixing block 3 is symmetrically arranged on the left and right sides of the front of the support base 1. The inside of the fixing block 3 can be fixedly connected to an iron cable, which can bind the test vehicle and effectively prevent the vehicle from moving during subsequent testing. At the same time, a hydraulic cylinder 5 is installed inside the fixing plate 4. A support plate 6 is set at the output end of the hydraulic cylinder 5, and an impact plate 7 is set on the front side of the support plate 6. A rubber pad 8 with a certain degree of elasticity is installed in the middle of the support plate 6 and the impact plate 7. Rotating rods 9 are set on the left and right sides of the inner side of the support plate 6 and the impact plate 7. The rotating rods 9 are connected to the support plate 6. The moving block 10, which is rotatably connected to the rear side of the impact plate 7, is also rotatably connected to the inner side of the impact plate 7. The outer side of the moving block 10 is fixedly connected to the impact plate 7 by a spring 11. When the hydraulic cylinder 5 is started, its output end can push the support plate 6 and the impact plate 7 to move forward to test the impact strength of the rear anti-collision beam of the car. At this time, the rubber pad 8 will be compressed, and the rotating rod 9 will rotate outward, which can make the moving block 10 move outward, and push the spring 11 to compress as well. This can effectively absorb part of the impact vibration and protect the hydraulic cylinder 5.
[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the rear anti-collision beam will generate some fragments upon impact. An installation block 12 is installed at the output end of the hydraulic cylinder 5. Protective plates 13 are set on the upper and lower sides of the outer side of the installation block 12. A locking hole 14 is opened at the lower middle part of the protective plate 13, and a locking pin 15 is installed at the upper middle part. The locking hole 14 and the locking pin 15 can be locked together, so that the protective plate 13 can be firmly installed on the outer side of the installation block 12. Secondly, a rotating plate 17 is rotatably set on the rear side of the outer side of the installation block 12. The rotating plate 17 can be rotated to lock together with the limiting blocks 16 set on the upper and lower sides of the rear of the protective plate 13, which can further strengthen the connection between the installation block 12 and the protective plate 13.
[0034] Secondly, prolonged use of the hydraulic cylinder 5 will cause some wear. Therefore, a sponge block 20 is installed on the outside of the output end of the hydraulic cylinder 5, and a protective cover 18 is installed on the outside of the sponge block 20 for protection. At the same time, a rotating cover 19 is rotatably installed on the front side of the protective cover 18. The lower part of the rotating cover 19 is engaged with the lower center front side of the protective cover 18, that is, the rotating cover 19 can be rotated open, and lubricating oil can be poured onto the sponge block 20. That is, when the hydraulic cylinder 5 is started, the sponge block 20 can apply lubricating oil to the hydraulic cylinder 5, which can effectively maintain the hydraulic cylinder 5 and thus greatly extend the service life of the hydraulic cylinder 5.
[0035] The working principle of this automotive rear anti-collision beam strength measuring device with a protective structure is as follows: A protective plate 13 is installed on the outside of the output end of the hydraulic cylinder 5. The protective plate 13 can block the fragments generated during the impact strength measurement of the anti-collision beam, thus preventing the fragments from flying around and effectively protecting the personal safety of the test personnel. At the same time, a shock-absorbing mechanism is installed on the output end of the hydraulic cylinder 5, which can effectively reduce the vibration damage to the hydraulic cylinder 5 during impact and effectively protect the hydraulic cylinder 5. In addition, a sponge block 20 is installed on the outside of the output end of the hydraulic cylinder 5. The sponge block 20 can absorb lubricating oil and apply it to the hydraulic cylinder 5 regularly, thereby effectively maintaining the hydraulic cylinder 5.
