Technical Field

[0001] This utility model relates to the field of automotive rear bumper beam testing technology, specifically an adjustable automotive rear bumper beam strength measuring device. Background Technology

[0002] Anti-collision beams can effectively absorb collision energy when a vehicle is involved in a low-speed collision. When testing vehicle performance, it is necessary to measure the strength of the rear anti-collision beam. The strength measurement device is used to impact the rear anti-collision beam to evaluate its performance in a real collision. Various methods for strength testing have been proposed on the market. A Chinese utility model patent with authorization announcement number CN222761838U discloses an automotive anti-collision beam strength testing device that mainly uses spring testing, but can also test the rear anti-collision beam by impacting it with the extension and retraction of a hydraulic rod.

[0003] Based on existing solutions and actual production and processing applications, the existing automotive rear bumper beam strength measuring equipment has a fixed position of the pressure block, which makes it inconvenient to adjust the height, front-to-back position, and tilt angle of the pressure block as needed. Therefore, we propose an adjustable automotive rear bumper beam strength measuring equipment to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable automotive rear bumper beam strength measuring device to solve the problem mentioned in the background art that the position of the pressure block in the existing automotive rear bumper beam strength measuring device is fixed, making it inconvenient to adjust the height, front-back position, and tilt angle of the pressure block as needed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable automotive rear bumper beam strength measuring device, comprising a base, a mounting plate, a first hydraulic rod, and a pressure block:

[0006] The base has connecting plates fixed at equal intervals on its bottom outer side. The base has rectangular slots at equal intervals inside. Connecting rings are installed at equal intervals on the inner wall of the rectangular slots of the base. Chain hooks are installed on the connecting rings.

[0007] The mounting plate is located above the base. Support frames are fixedly installed at both the front and rear ends of the upper surface of the mounting plate. A side plate is provided on the inner side of the support frame, and a rectangular frame is fixed at the outer end of the side plate. A first hydraulic rod is rotatably installed on the inner side of the side plate, and a pressure block is fixed at the output end of the first hydraulic rod. A U-shaped frame is fixed on the lower surface of the side plate, and a second hydraulic rod is rotatably installed at the bottom end of the U-shaped frame.

[0008] Preferably, the base has equally spaced screw holes inside, and the mounting plate is fixedly connected to the base by screws.

[0009] Preferably, both the side plate and the rectangular frame are fixedly connected to the support frame by screws, the left end of the support frame extends through the interior of the rectangular frame, and the support frame has a zigzag structure.

[0010] Preferably, the side plates are symmetrically arranged about the centerline of the first hydraulic rod.

[0011] Preferably, the output end of the second hydraulic rod is rotatably connected to the arc-shaped block at the bottom end of the first hydraulic rod.

[0012] Preferably, a pressure sensor is installed at the end of the pressure block near the output end of the first hydraulic rod.

[0013] Preferably, hooks are fixed at both the beginning and end of the chain.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the adjustable automobile rear bumper beam strength measuring device can adjust the front and rear position, up and down position and tilt angle of the pressure block to adapt to automobile rear bumper beams of different heights, and facilitate the adjustment of the detection angle during strength measurement.

[0015] 1. The base has equally spaced screw holes inside. The mounting plate is fixedly connected to the base by screws. By moving the mounting plate back and forth on the base, the front and back positions of the pressure block on the mounting plate can be adjusted, which can adjust the part of the pressure block that impacts the rear anti-collision beam of the car.

[0016] 2. Lift the side panels and rectangular frame on the outside of the support frame, and then fix them with screws. Adjust the height of the pressure blocks indirectly connected to the side panels to adapt to the rear bumper beams of different heights.

[0017] 3. A second hydraulic rod is rotatably mounted at the bottom of the U-shaped frame. The output end of the second hydraulic rod is rotatably connected to the arc-shaped block at the bottom of the first hydraulic rod. The extension and retraction of the second hydraulic rod drives the first hydraulic rod to rotate, which in turn drives the pressure block to rotate.
