Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision beam bending test device, specifically an anti-collision beam bending test device for new energy vehicles. Background Technology

[0002] When testing the bending of the anti-collision beam of a new energy vehicle, multiple tests are required. This inevitably generates a lot of heat in the impacted part of the anti-collision beam, affecting subsequent tests. Furthermore, a single impact plate cannot reflect different test scenarios. The anti-collision beam needs to be removed from the original clamping plate and placed into a new device for testing, which is very time-consuming, labor-intensive, and inefficient.

[0003] Document CN 108896410 A discloses a bending test device for automotive anti-collision beams, comprising support legs, a base plate, a slider, a first spring, a first vertical plate, a support plate, and a hinge plate. Support legs are connected to the left and right sides of the bottom of the base plate, and sliding grooves are formed on the left and right sides of the top of the base plate. A slider is installed within the sliding grooves, and the outer side of the slider is connected to the base plate by a first spring. This device uses water spray to reduce heat during cooling. However, if the water sprayed onto the anti-collision beam is not completely dry, the surface of the anti-collision beam is prone to slippage during testing, introducing errors into the test and resulting in inaccurate data.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses a bending test device for anti-collision beams of new energy vehicles, which effectively improves the testing efficiency of anti-collision beam bending tests and improves the accuracy of test data by using a cooling fan to dissipate heat from the beam.

[0006] The technical solution of this utility model is: a bending test device for anti-collision beams of new energy vehicles, including a base and a clamping structure and a test structure located on the base. The base has a downward groove in the middle, and the clamping structure is located on both sides of the groove. The test structure includes a support frame, a hydraulic cylinder and a pressure plate mold. The bottom of the pressure plate mold is provided with an impact plate that contacts the anti-collision beam. The impact plate is of arbitrary shape. A cooling fan is provided at the position below the pressure plate mold between the clamping structures, facing the impact plate and the anti-collision beam.

[0007] By adopting the above technical solution, the anti-collision beam is placed into the clamping structure and then clamped by the clamping structure. Then, the impact plate is pushed by the hydraulic cylinder, so that the impact plate impacts the anti-collision beam. Finally, the bending degree of the anti-collision beam is measured, and the test of the anti-collision beam is completed.

[0008] Preferably, the clamping structure includes a U-shaped bracket located on both sides of the base groove, a threaded rod threaded through the center of the top of the bracket, and a pressing plate for fixing the anti-collision beam at the bottom of the threaded rod.

[0009] By adopting the above technical solution, when the anti-collision beam is sent into the U-shaped bracket of the clamping structure, the threaded rod is tightened, and the pressing plate at the bottom of the threaded rod presses down to press the anti-collision beam, which facilitates the bending test of the impact plate under the push of the hydraulic cylinder.

[0010] Preferably, the distance between the pressing plate and the bottom of the inner side of the bracket is greater than the thickness of the anti-collision beam, which makes it easier to insert the anti-collision beam into the position between the pressing plate and the bracket, and the clamping structures on both sides of the groove are symmetrically arranged.

[0011] By adopting the above technical solution, when the anti-collision beam is positioned between the bracket and the pressure plate, tightening the threaded rod and then pressing the pressure plate against the anti-collision beam ensures that the anti-collision beam is properly positioned.

[0012] Preferably, the support frame is located on both sides of the clamping structure, the top of the support frame is provided with a support plate, the support plate is located at the top of the clamping structure, and a hydraulic cylinder is provided at the center of the support plate.

[0013] By adopting the above technical solution, a driving force is provided when impacting the anti-collision beam, so that the impact plate has a downward impact force.

[0014] Preferably, the output end of the hydraulic cylinder is connected to a threaded rod via a push rod, the bottom of the threaded rod is connected to a pressure plate mold, and the center of the top of the pressure plate mold is provided with an inward threaded hole that fits and tightens with the screw rod.

[0015] By adopting the above technical solution, the impact plate at the end of the threaded rod can be replaced according to the shape of the anti-collision beam or the different testing requirements. In this way, it can be adapted to different requirements without replacing the entire device.

[0016] Preferably, the impact plate is in the shape of a flat plate, a corrugated plate, a conical plate, or a wedge plate, and the impact plate protrudes from the surface of the pressure plate mold.

[0017] By adopting the above technical solution, the shape of the impact plate is not limited to the above shape, and any shape desired by the customer can be simulated for impact testing.

[0018] Preferably, the cooling fan is positioned directly opposite the impact point of the anti-collision beam and the impact plate, and the cooling fan is connected to the bottom of the support plate via an L-shaped bracket.

[0019] By adopting the above technical solution, after multiple impacts on the anti-collision beam, a high amount of heat will be generated. This could affect and deviate from the data of subsequent impacts. By using a cooling fan to dissipate the heat during and after the impact, no error will be caused in subsequent impact tests, thus ensuring accurate impact data.

[0020] Preferably, the cooling fan is connected to an external power source.

[0021] The advantages of this utility model are: 1. When this utility model is used to test the anti-collision beam, the impact plate at the end of the threaded rod can be replaced according to the type of anti-collision beam and the test requirements. It has a high degree of adaptability, meets different test needs, does not require overall replacement, and improves the efficiency of the test.

[0022] 2. This utility model provides a cooling fan on the side of the anti-collision beam, which can dissipate the heat generated by the impact plate hitting the anti-collision beam multiple times, preventing deviations in test data due to heat, ensuring test accuracy, and improving the accuracy of the data.

[0023] 3. This utility model effectively improves the testing efficiency of the anti-collision beam bending test, and the cooling fan can effectively improve the accuracy of the test data. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-2 As shown, the new energy vehicle anti-collision beam bending test device includes a base 1 and a clamping structure and a test structure located on the base 1. The base 1 has a downward groove 101 in the middle. The clamping structure is located on both sides of the groove 101. The test structure includes a support frame 2, a hydraulic cylinder 4 and a pressure plate mold 5. The bottom of the pressure plate mold 5 is provided with an impact plate 6 that contacts the anti-collision beam. The impact plate 6 can be of any shape. A cooling fan 13 is provided below the pressure plate mold 5 between the clamping structure and faces the impact plate 6 and the anti-collision beam. The anti-collision beam is placed into the clamping structure and then clamped by the clamping structure. Then, the impact plate is pushed by the hydraulic cylinder 4, so that the impact plate 6 impacts the anti-collision beam. Finally, the bending degree of the anti-collision beam is measured to complete the test of the anti-collision beam.

[0034] The clamping structure includes a U-shaped bracket 10 located on both sides of the base groove 101. A threaded rod 11 is threaded through the center of the top of the bracket 10. A pressing plate 12 for fixing the anti-collision beam is provided at the bottom of the threaded rod 11. When the anti-collision beam is sent into the U-shaped bracket 10 of the clamping structure, the threaded rod 11 is tightened. The pressing plate 12 at the bottom of the threaded rod 11 then presses down to press the anti-collision beam, which facilitates the bending test of the impact plate under the push of the hydraulic cylinder 4.

[0035] The distance between the inner bottom of the pressing plate 12 and the bracket 10 is greater than the thickness of the anti-collision beam, making it easier to snap the anti-collision beam into the position between the pressing plate 12 and the bracket 10. The clamping structures on both sides of the groove 101 are symmetrically arranged. When the anti-collision beam is placed between the bracket and the pressing plate 12, the pressing plate 12 is pressed against the anti-collision beam by tightening the threaded rod 11, so that the anti-collision beam is just right.

[0036] Support frame 3 is located on both sides of the clamping structure. Support plate 3 is provided on the top of support frame 2. Support plate 3 is located at the top of the clamping structure. Hydraulic cylinder 4 is provided at the center of support plate 3 to provide driving force when impacting the anti-collision beam, so that the impact plate 6 has a downward impact force.

[0037] The output end of hydraulic cylinder 4 is connected to threaded rod 11 via push rod 8, and the bottom of threaded rod 11 is connected to pressure plate mold 5, as shown below. Figure 7 As shown, the pressure plate mold 5 has an inward threaded hole 7 at the top center position, which is tightened and fixed with the screw 9. Depending on the shape of the anti-collision beam or the different testing requirements, the impact plate 6 at the end of the threaded rod 11 can be replaced. In this way, it can be adapted to different requirements without replacing the entire device.

[0038] like Figure 3-6 As shown, the shape of the impact plate 6 is a flat plate 601, a wave-shaped plate 602, a conical plate 603, or a wedge-shaped plate 604. The impact plate 6 protrudes from the surface of the pressure plate mold 5. The shape of the impact plate 6 is not limited to the above shapes and can simulate any shape desired by the customer for impact testing.

[0039] The cooling fan 13 is positioned directly opposite the impact point of the anti-collision beam and impact plate. The cooling fan 13 is connected to an external power source and is connected to the bottom of the support plate 3 via an L-shaped bracket. After multiple impacts with the anti-collision beam, high heat will be generated, which could affect and deviate from the data of subsequent impacts. The cooling fan 13 dissipates the heat during and after the impact, preventing errors in subsequent impact tests and ensuring accurate impact data.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
