Description

Technical Field

[0001] This utility model relates to the field of front bumper testing technology, specifically a testing device for a front bumper system. Background Technology

[0002] The front bumper is a plastic component installed at the front of a vehicle, acting as a buffer when the car collides with an object or pedestrian. Because front bumpers are typically made of plastic, they reduce the risk of injury when a car contacts a pedestrian. As a critical part of the vehicle, the performance of the front bumper directly affects the vehicle's safety level in a collision. To accurately assess the front bumper's crashworthiness, energy absorption, and pedestrian protection capabilities, simulated crash tests using specialized testing equipment are usually required.

[0003] However, in simulated crash tests of car front bumpers, traditional testing equipment has significant problems in adjusting the weight of the impact components. Specifically, traditional equipment typically relies on replacing impact components of different weights to simulate different intensities and types of collisions. This approach not only increases testing costs because it requires preparing impact components of various weights, but also reduces testing efficiency because replacing impact components requires additional time and manpower.

[0004] Based on this, a testing device for a front bumper system is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for a front bumper system to solve the problems of high cost and low efficiency in adjusting the weight of impact components in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A testing device for a front bumper system includes a test box, a test base installed at the bottom of the test box, slide rails symmetrically fixed on the left and right sides inside the test box, and grooves formed at opposite ends of the two slide rails. A threaded groove is formed inside the test box, and a height adjustment structure is provided inside the threaded groove. A connecting structure is provided on the height adjustment structure, and the connecting structure is connected to an impact component.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4 As shown, a testing device for a front bumper system includes a test box 1. A test base 14 is installed at the bottom of the test box 1. Slide rails 13 are symmetrically fixed on the left and right sides inside the test box 1. Slide grooves 131 are formed at opposite ends of the two slide rails 13. A threaded groove 15 is formed inside the test box 1. A height adjustment structure 2 is provided inside the threaded groove 15. A connecting structure 3 is provided on the height adjustment structure 2. The connecting structure 3 is connected to an impact member 4.

[0026] In this embodiment, firstly, the impact member 4 is fixed using the connecting structure 3. Then, the height of the connecting structure 3 and the fixed impact member 4 is adjusted using the height adjustment structure 2. Subsequently, the front bumper to be tested is placed on the test base 14, and the connection between the connecting structure 3 and the impact member 4 is disconnected. At this time, the impact member 4 falls freely under the action of gravity and impacts the bumper to be tested at high speed, thereby completing the test of its impact resistance performance.

[0027] In an optional embodiment, the height adjustment structure 2 includes a motor 201 mounted on the upper end of the test box 1. The output end of the motor 201 extends into the threaded groove 15 and is fixedly connected to an adjusting screw 202. An adjusting block 203 slides inside the threaded groove 15. The adjusting screw 202 is threadedly connected to the adjusting block 203. An auxiliary plate 204 is fixed to the front end of the adjusting block 203. Side grooves 205 matching the slide rail 13 are opened on both sides of the auxiliary plate 204. A connecting structure 3 is provided on the auxiliary plate 204.

[0028] It should be noted that, driven by the motor 201, the adjusting screw 202 rotates, thereby causing the adjusting block 203 to move vertically along the threaded groove 15. This movement causes the auxiliary plate 204 to move up and down, and the adjusting block 203 also drives the connecting structure 3 and its connected impact member 4 to move vertically together. In this way, the height position of the connecting structure 3 and its connected impact member 4 can be adjusted, thereby controlling the impact force of different intensities applied by the impact member 4 to the bumper under test. By providing side grooves 205 on both sides of the auxiliary plate 204 that match the slide rail 13, the height adjusting structure 2 can remain stable when adjusting the auxiliary plate 204, the connecting structure 3 at the upper and lower ends of the auxiliary plate 204, and the impact member 4, and ensure the accuracy of the subsequent impact of the impact member 4 on the front bumper placed on the test base 14.

[0029] In an optional embodiment, the connection structure 3 includes a controller 301 mounted on the upper end of the auxiliary plate 204 and an electromagnet block 302 disposed on the lower end of the auxiliary plate 204, wherein the controller 301 is electrically connected to the electromagnet block 302.

[0030] It should be noted that the controller 301 can control the on and off of the electromagnet block 302, thereby controlling the electromagnet block 302 to gain magnetism and lose magnetism, and thus controlling the connection and disconnection between the electromagnet block 302 and the impact member 4.

[0031] In an optional embodiment, the top centerline of the test base 14 and the bottom centerline of the impact member 4 are on the same vertical horizontal plane.

[0032] It should be noted that this alignment method not only improves the accuracy of the test, but also helps to reduce deviations and uncertainties during the test process. When the bottom center line of the impact component 4 is completely aligned with the top center line of the test base 14, the impact force can be more evenly distributed on the front bumper under test, thus more realistically simulating actual collision conditions.

[0033] In an optional embodiment, the impact member 4 includes an iron plate 401, on which sliders 402 matching the slide groove 131 are symmetrically fixed on the left and right sides. A fixing block 403 is fixedly installed at the lower end of the iron plate 401, and a collision block 405 is fixed at the lower end of the fixing block 403. The collision block 405 is located directly above the test base 14. A configuration slot 404 is opened at the front end of the fixing block 403, and a counterweight 41 is provided inside the configuration slot 404.

[0034] It should be noted that the impact block 405 is located directly above the test base 14 and is used to impact the front bumper to be tested. The front end of the fixing block 403 has a configuration slot 404, inside which a counterweight 41 is installed to adjust the total weight of the impact member 4, thereby controlling the impact force during impact. Furthermore, the slider 402 matches the slide groove 131, ensuring the stability of the impact member 4 during vertical movement and ensuring that when the impact member 4 is raised to the required height and ready to be released, the slider 402 will slide steadily down the slide groove 131, ensuring that the impact block 405 accurately impacts the front bumper on the test base 14.

[0035] In an optional embodiment, the counterweight 41 includes an array of counterweight screws 411 fixed inside the configuration slot 404 and a plurality of counterweight rings 412 threaded onto the counterweight screws 411.

[0036] It should be noted that the counterweight ring 412 can be easily added to or removed from the counterweight screw 411 by rotating it, thus achieving precise adjustment of the weight of the impact component 4. This operation is simple and easy to perform, while providing extremely high flexibility. Because the process of adding or removing the counterweight ring 412 is simple and quick, the weight of the impact component 4 can be rapidly adjusted according to different testing needs to meet the requirements of various bumper tests. This not only improves testing efficiency but also makes the testing device more widely applicable to various types of bumper tests.

[0037] In an optional embodiment, the front end of the test chamber 1 is hinged from top to bottom to have an upper test door 11 and a lower test door 12, and the front end of the lower test door 12 is provided with an observation window.

[0038] It should be noted that the front end of the test box 1 is hinged from top to bottom with an upper test door 11 and a lower test door 12, which facilitates the installation and removal of the front bumper to be tested. The front end of the lower test door 12 is provided with an observation window for easy observation of the test process.

[0039] In an optional embodiment, a sensor 51 is provided at the front end of the test base 14, and a sensor 52 is provided at the front end of the collision block 405. The sensor 51 and the sensor 52 are on the same vertical horizontal line.

[0040] It should be noted that the design of sensor 51 at the front end of test base 14 and sensor 52 at the front end of collision block 405 on the same vertical horizontal line not only improves the accuracy and reliability of the test, but also provides a solid foundation for subsequent data analysis and result evaluation.

[0041] The above embodiment discloses a testing device for a front bumper system. First, the upper test door 11 and lower test door 12 of the test chamber 1 are opened. By rotating the counterweight ring 412, it can be easily added to or removed from the counterweight screw 411, thereby adjusting the weight of the impact component. Next, the controller 301 controls the electromagnet block 302 to be energized, making it magnetic and thus attracting the impact component 4. The motor 201 is started, and its output drives the adjusting screw 202 to rotate, causing the adjusting block 203 to slide up and down within the threaded groove 15, thereby adjusting the height of the impact component 4. According to the testing requirements, the impact component 4 is adjusted to a suitable height position.

[0042] Subsequently, the front bumper to be tested is placed on the test base 14, and the upper test door 11 and lower test door 12 are closed to ensure the sealing of the test environment. After confirming that the impact component 4 has been adjusted to the required height, the electromagnet block 302 is de-energized by the controller 301, causing it to lose its magnetism and thus releasing the impact component 4. The impact component 4 falls freely under the action of gravity, and the collision block 405 at its bottom impacts the front bumper to be tested at high speed.

[0043] During the impact, sensor 51 at the front end of test base 14 and sensor 52 at the front end of impact block 405 record relevant impact data, such as impact force and impact time. This data can be used for subsequent data analysis and result evaluation to determine whether the front bumper's impact resistance performance meets the requirements.

[0044] After the test is completed, open the lower test door 12 to check the damage to the front bumper and record the test results. Clean the inside of the test chamber 1 in preparation for the next test.
