Technical Field

[0001] This utility model relates to the technical field of automotive rear bumper beam strength measurement equipment, specifically an automotive rear bumper beam strength measurement equipment with a limiting structure. Background Technology

[0002] A car crash beam is a device used to absorb collision energy when a vehicle is involved in a collision. It mainly consists of a main beam, an energy-absorbing box, and a mounting plate connecting to the vehicle. Its primary function is to effectively absorb collision energy during low-speed collisions, minimizing damage to the vehicle's longitudinal beams and thus protecting the vehicle. When inspecting a car crash beam, strength testing is required using a testing device.

[0003] The existing technical solutions have the following drawbacks, such as: the existing strength testing devices are not convenient to automatically adjust the position of the strength testing device according to the needs due to the different installation and placement positions of the car anti-collision beam. Therefore, this utility model provides a car rear anti-collision beam strength measuring device with a limiting structure to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a strength measuring device for automotive rear anti-collision beams with a limiting structure, so as to solve the problem mentioned in the background art that the existing strength testing devices are not convenient to automatically adjust the position of the strength testing device according to the needs due to the different installation and placement positions of automotive anti-collision beams.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle rear anti-collision beam strength measuring device with a limiting structure, comprising: a connecting base plate, and a mounting base disposed on the connecting base plate, wherein a strength impact block for conducting impact tests is disposed on the upper side of the mounting base, and further comprising:

[0006] A connecting motor is connected to the outside of the mounting base, and an adjustable component is provided inside the mounting base. A parallel plate is connected to the upper surface of the mounting base, and an outer support plate is welded and fixed to the outside of the upper surface of the parallel plate.

[0007] An installation block is connected to the inner side of the outer support plate, and an electric hydraulic rod is installed inside the installation block. A reinforcement component is installed inside the parallel plate.

[0008] As a preferred technical solution of this utility model, the outer side of the connecting base plate is welded with connecting reinforcement plates at equal intervals, and the longitudinal section of the connecting reinforcement plates is a triangular structure.

[0009] As a preferred embodiment of this utility model, the adjustment component includes a first connecting rod installed at the output end of the connecting motor, and a second connecting rod is connected inside the mounting base.

[0010] As a preferred embodiment of this utility model, the first connecting rod and the parallel plate are connected by a thread, and the parallel plate is slidably connected to the second connecting rod.

[0011] As a preferred embodiment of this utility model, the reinforcing component includes a positioning hole formed in the mounting base, and a connecting rod is connected inside the positioning hole.

[0012] As a preferred embodiment of this utility model, the parallel plate is connected to the upper surface of the mounting base, and the parallel plate is connected to the mounting base through a connecting rod, which reinforces the parallel plate.

[0013] As a preferred embodiment of this utility model, a triangular plate is provided on the outer side of the outer support plate, and the triangular plate is provided in a one-to-one correspondence with the outer support plate.

[0014] As a preferred embodiment of this utility model, the outer support plate and the parallel plate form a triangular structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the strength measuring device for a car rear anti-collision beam with a limiting structure can adjust the position of the strength testing device according to the position of the anti-collision beam by adjusting the setting of the components. Moreover, with the installation of the reinforcement components, the testing device can be reinforced and limited before strength testing to prevent shaking during testing and affect the testing effect.

[0016] By stably installing the connecting reinforcement plate on the outside of the connecting base plate, the bottom of the connecting base plate is stably reinforced. At the same time as the impact, because the upper surface of the mounting base is connected to the parallel plate, and the outer support plate is welded and fixed to the outer side of the upper surface of the parallel plate, the outer support plate and the parallel plate form a triangular structure. Through the setting of the outer support plate, the start of the electric hydraulic rod drives the electric hydraulic rod to drive the strength impact block connected to the electric hydraulic rod to start simultaneously. The strength impact block is aligned with the car, and the strength impact is carried out by moving the strength impact block to perform strength testing. The operation is convenient.

[0017] The first connecting rod is connected to the parallel plate by a thread, the parallel plate is slidably connected to the second connecting rod, and the other end of the parallel plate slides on the outside of the second connecting rod. This allows the strength impact block to be moved according to the position of the rear anti-collision beam of the vehicle, automatically adjusting the measuring device, which is easy to operate.

[0018] The parallel plates are reinforced by connecting them to the mounting base via connecting rods. Positioning holes are evenly spaced inside the mounting base. When the holes on the parallel plates are aligned with the appropriate positioning holes, the connecting rod is inserted through the parallel plates and rotated to connect with the appropriate positioning holes. This reinforces the moved parallel plates and prevents them from shaking during strength testing when the electric hydraulic rod is activated, thus ensuring their usability.

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a vehicle rear anti-collision beam strength measuring device with a limiting structure, including a connecting base plate 1, a connecting reinforcement plate 2, a mounting base 3, a connecting motor 4, a first connecting rod 5, a second connecting rod 6, a parallel plate 7, a connecting rod 8, an outer support plate 9, a mounting block 10, an electric hydraulic rod 11, a triangular plate 12, a strength impact block 13, and a positioning hole 14.

[0027] When using this automotive rear bumper beam strength measuring device with a limiting structure, the specific steps are as follows: Figure 1 and Figure 2 In this process, the car to be tested is parked on the outside of the mounting base 3. The mounting base 3 is mounted on the connecting base plate 1, and a high-strength impact block 13 for impact testing is installed on the upper side of the mounting base 3. The impact block 13 is aligned with the car. Simultaneously, a mounting block 10 is connected to the inner side of the outer support plate 9, and an electro-hydraulic rod 11 is installed inside the mounting block 10. Activating the electro-hydraulic rod 11 simultaneously activates the impact block 13 connected to it, aligning it with the car and performing a moving impact. The operation is convenient. Connecting plates are welded at equal intervals on the outer side of the connecting base plate 1. The reinforcing plate 2, and the longitudinal section of the connecting reinforcing plate 2 is a triangular structure, will stably reinforce the bottom of the connecting base plate 1 by installing the connecting reinforcing plate 2 stably on the outside of the connecting base plate 1. At the same time as the impact, the upper surface of the mounting base 3 is connected to the parallel plate 7, and the outer support plate 9 is welded and fixed to the outer side of the upper surface of the parallel plate 7. The outer support plate 9 and the parallel plate 7 form a triangular structure. Through the setting of the outer support plate 9, a triangular plate 12 is set on the outer side of the outer support plate 9, and the triangular plate 12 is set one-to-one with the outer support plate 9. The mounting block 10 is installed by bolts, and then the electric hydraulic rod 11 is installed into the mounting block 10 for easy operation.

[0028] Specific examples Figure 3 , Figure 4 and Figure 5In this system, after the car is parked outside the mounting base 3, a connecting motor 4 is connected to the outside of the mounting base 3 according to the car's parking position. An adjustable component is installed inside the mounting base 3, including a first connecting rod 5 installed at the output end of the connecting motor 4 and a second connecting rod 6 connected inside the mounting base 3. Activating the connecting motor 4 causes the first connecting rod 5 at its output end to rotate. Since the first connecting rod 5 is threadedly connected to the parallel plate 7, when the first connecting rod 5 rotates, it causes the parallel plate 7 to move accordingly. The parallel plate 7 slides, and is slidably connected to the second connecting rod 6. The other end of the parallel plate 7 slides outside the second connecting rod 6, thereby moving the impact block 13 according to the position of the rear anti-collision beam of the car. This automatically adjusts the measuring device, making it easy to operate. Simultaneously, after the parallel plate 7 is adjusted to a suitable position, and a reinforcing component is installed inside the parallel plate 7, the reinforcing component includes a positioning hole 14 opened in the mounting base 3, and a connecting rod 8 is connected inside the positioning hole 14. The parallel plate 7 is connected to the upper surface of the mounting base 3, and the parallel plate 7 is connected to the mounting base 3 through the connecting rod 8. Since the positioning holes 14 are opened at equal intervals inside the mounting base 3, when the hole-like structure on the parallel plate 7 is aligned with the appropriate positioning hole 14, and the connecting rod 8 is inserted through the interior of the parallel plate 7, the connecting rod 8 is connected to the appropriate positioning hole 14 by rotating it, thereby reinforcing the moved parallel plate 7 and preventing the parallel plate 7 from shaking when the electric hydraulic rod 11 is started for strength testing, which would affect its use. This is the usage method of the automotive rear anti-collision beam strength measuring device with a limiting structure.
