Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle detection, in particular to a whole vehicle rain and water wading test device. Background Art

[0002] Electric vehicles are powered by electric motors and equipped with key electrical equipment such as power batteries and controllers. This requires the entire vehicle to possess excellent insulation performance. However, in actual use, electric vehicles are inevitably exposed to rain or driving on flooded roads. If the vehicle's sealing performance is poor, driving through water will significantly weaken the insulation and voltage resistance of its live components. Therefore, it is particularly important to conduct rigorous water spray and water wading tests on electric vehicles before they leave the factory. These tests are designed to simulate actual water wading environments, facilitate leakage detection of electric vehicles, and comprehensively evaluate their performance and safety in water wading conditions.

[0003] Traditional methods for testing electric vehicles in rain and water often involve digging a canal at the test site and filling it with water to simulate a wading environment. The test then relies on human riders to conduct the test. However, this testing method is not only inefficient, resulting in unnecessary waste of manpower and water resources, but is also severely limited by the conditions of the test site, making it difficult to fully reflect the performance of electric vehicles in real-world wading and rainy environments. First, human rider testing is not only labor-intensive but can also lead to unstable test results due to human factors. Differences in rider strength, speed, and reaction time can all affect the test results, making it difficult for the test data to accurately reflect the actual performance of the electric vehicle. Second, traditional testing methods also have shortcomings in terms of safety and diversity. Due to the limitations of human riders, the test process may not fully consider the performance of the electric vehicle under extreme conditions, making it impossible to fully evaluate the safety performance of the electric vehicle.

[0004] In addition, due to the limitations of test sites and equipment, many current test devices are designed for a single test environment and cannot simulate both rain and wading conditions at the same time, which affects the integrity of the test results. Summary of the Invention

[0005] In response to the problems existing in the existing technology, the utility model provides a whole-vehicle rain and water testing equipment, which can realize the simultaneous implementation of rain and water testing, avoiding the tedious process of performing two tests separately in traditional testing methods, and is suitable for testing electric vehicles of different sizes and types, with strong versatility and applicability.

[0006] The utility model is realized as follows: a whole vehicle rain wading test device includes a wading trough, in which a front wheel roller and a rear wheel roller are rotatably provided. The front wheel roller and the rear wheel roller are respectively arranged on both sides of the inner cavity of the wading trough along the length direction of the wading trough. A clamping rod for fixing the front wheel is provided in the wading trough at the position of the front wheel roller;

[0007] A water spraying assembly for spraying electric vehicles is provided on one side of the wading trough. The water spraying assembly includes a water spraying nozzle, a variable frequency water pump and a water tank. The variable frequency water pump is connected to the water tank, and the water spraying nozzle is connected to the variable frequency water pump through a water pipe.

[0008] Furthermore, a ball screw assembly is provided in the wading trough located on the side of the front wheel roller, wherein the screw rod in the ball screw assembly is vertically provided on the side wall of the wading trough, and the upper end portion of the screw rod extends upward out of the wading trough and is provided with an adjusting hand wheel;

The lifting bracket includes mounting portions located on either side of the front wheel, each with a socket provided therein. Two clamping rods are provided, each inserted into a socket in the mounting portion on either side of the front wheel to clamp the front wheel. Driven by the ball screw assembly, the lifting bracket can precisely adjust the height of the clamping rods to tightly clamp the front wheel of the electric vehicle. This stable clamping method not only ensures the stability of the electric vehicle during testing, but also improves the safety and reliability of the test.

[0010] Furthermore, a frame is provided along the length of the inner bottom plate of the wading trough, and the front and rear rollers are both mounted on the upper end surface of the frame via mounting brackets. A fixing groove is provided along the length of the upper end surface of the frame at the location of the rear axle rollers, and a fastener is provided on the mounting bracket for the rear rollers. The mounting bracket is secured to the upper end surface of the frame via the fasteners and the fixing grooves. This design simplifies the installation and commissioning of the rear rollers. Testers can easily adjust the position of the mounting bracket as needed to adjust the wheelbase and accommodate testing of electric vehicles of different sizes.

[0011] Furthermore, the insertion holes are provided in plurality and are evenly spaced along the length of the mounting portion. By inserting the insertion holes at different positions, the device can adapt to electric vehicle front wheels of different sizes, thereby meeting a wider range of testing needs.

[0012] Furthermore, guide columns are provided on both sides of the screw rod, and the connecting portion of the lifting bracket is slidably connected to the guide columns.

[0013] Furthermore, a driven sprocket is provided on the mounting shaft of the front wheel roller, and a drive motor is provided on the bottom plate of the wading trough near the front wheel roller. A driving sprocket is provided on the output shaft of the drive motor. The driving sprocket and the driven sprocket are driven by a chain. The drive motor is a waterproof motor. By actively driving the front wheel roller with the drive motor, the dynamic state of the electric vehicle during real driving can be simulated, making the test more realistic. This ensures that the electric vehicle remains stable during the test, avoiding shaking or deviation caused by water impact or uneven ground, which helps to improve the accuracy and reliability of the test.

[0014] Furthermore, a water entry slope is provided inside the wading trough at the water inlet and outlet sides, and a ramp connected to the water entry slope is provided outside the wading trough at the water inlet and outlet sides. The provision of the water entry slope and ramp allows the electric vehicle to smoothly transition when entering and exiting the wading trough, avoiding the shock and jolt caused by sudden entry or exit from the water surface.

[0015] Furthermore, a counterweight that can be tied to the saddle of the electric vehicle is provided in the wading trough.

[0016] Furthermore, there are multiple water spray nozzles, and the multiple water spray nozzles are evenly distributed along the length direction of the wading trough.

[0017] Furthermore, the wading trough is provided with a water inlet pipe and a water outlet pipe which are connected with the inner cavity of the wading trough, and the lower end surface of the water outlet pipe is flush with the upper end surface of the bottom plate of the wading trough.

[0018] The advantages and technical effects of this utility model are as follows: Due to the adoption of the above technical solution, rain and water testing can be performed simultaneously, avoiding the tedious process of performing the two tests separately in traditional testing methods. The utility model is also suitable for testing electric vehicles of different sizes and types, and has strong versatility and applicability. It improves testing efficiency, has the advantages of effectively simulating real environments, comprehensive testing performance, simple and safe operation, strong applicability and flexible adjustment, and improved product quality.

The water spray assembly, including a water spray nozzle, a variable frequency water pump, and a water tank, can simulate rain impacts of varying intensities and angles, allowing the entire electric vehicle to be rain tested. This helps to test the sealing and insulation performance of electric vehicles in rainy environments. BRIEF DESCRIPTION OF THE DRAWINGS
