Technical Field

[0001] This invention relates to the field of vehicle testing technology, and in particular to a vehicle wading test device. Background Technology

[0002] Existing vehicle wading test devices and methods can only determine whether a vehicle can pass through a pool of water at a preset depth, but it is difficult to measure the power margin of a vehicle when passing through a pool of water at a preset depth and the power situation when it fails to pass through.

[0003] Existing vehicle wading tests mainly involve personnel driving vehicles through pools of water of a predetermined depth. This method can only qualitatively determine whether a vehicle can pass through, and it is difficult to quantitatively evaluate the vehicle's power performance when wading. Summary of the Invention

[0004] This invention provides a vehicle wading test device to solve the technical problem that related technologies can only qualitatively determine whether a vehicle can pass through water, and it is difficult to quantitatively evaluate the vehicle's power performance when wading.

[0005] This invention provides a vehicle wading test apparatus, the test apparatus comprising: The test pool is used to contain the test water. A sliding module, wherein the sliding module is disposed at the bottom of the test pool; A tensile testing assembly, which is connected to the vehicle to be tested and the test tank; An adjustable water pump is positioned toward the front of the vehicle under test; The vehicle to be tested is placed on the sliding module, so that the sliding module, the adjustable water pump and the vehicle to be tested are in multiple different preset test states, so as to conduct a water wading test on the vehicle to be tested.

[0006] In some embodiments, placing the vehicle under test on the sliding module, such that the sliding module, the adjustable water pump, and the vehicle under test are in multiple different preset test states, to conduct a wading test on the vehicle under test, includes: Place the vehicle to be tested on the sliding module and lock the sliding module, then adjust the water depth of the test pool to the first preset depth; The test vehicle and the test pool are connected by the connecting rope in the tensile testing assembly, and the tensile gauge in the tensile testing assembly is connected to the rear of the test vehicle. The water flow rate is controlled by an adjustable water pump to make the water flow rate in the test tank reach the first preset speed. Gradually increase the throttle opening of the vehicle under test until the tension reaches its maximum value, and obtain the tension value during the test; Calculate the actual ratio of the average tension to the weight of the vehicle under test within the first preset time period when the vehicle under test slips. Compare the actual ratio with the standard ratio. If the actual ratio is greater than the standard ratio, the vehicle under test passes the test at the first preset depth. If the actual ratio is not greater than the standard ratio, the vehicle under test fails the test at the first preset depth.

[0007] In some embodiments, the step of connecting the test vehicle and the test pool using a connecting rope in the tensile testing assembly, and connecting the tensile gauge in the tensile testing assembly to the rear of the test vehicle, further includes: Connecting rings are installed on both sides of the front and rear of the vehicle to be tested; Connecting anchor points are set on the inner wall of the test pool, corresponding to each connecting ring. The height of the connecting anchor points is adjusted so that the height of the connecting anchor points is consistent with the height of the corresponding connecting rings.

[0008] In some embodiments, the step of connecting the test vehicle and the test pool using a connecting rope in the tensile testing assembly, and connecting the tensile gauge in the tensile testing assembly to the rear of the test vehicle, further includes: The tensile tester is placed in the test tank and positioned on the centerline of the vehicle to be tested, with the tensile tester and the connecting ring at the same height. Connect the dynamometer to the two connecting rings at the rear of the vehicle to be tested.

[0009] In some embodiments, placing the vehicle under test on the sliding module, such that the sliding module, the adjustable water pump, and the vehicle under test are in multiple different preset test states, to conduct a wading test on the vehicle under test, includes: Place the vehicle to be tested on the sliding module and adjust the water depth of the test pool to the second preset depth; The vehicle to be tested and the test pool are connected by a connecting rope from the tensile testing assembly. Adjust the throttle opening of the vehicle to be tested until the wheels slip and reach the second preset speed; The wheels are allowed to continuously rotate for a second preset time. If the vehicle under test maintains normal operation under preset conditions within the second preset time, the vehicle under test is qualified for wading reliability at the second preset depth. If the vehicle under test fails to maintain normal operation under preset conditions within the second preset time, the vehicle under test is unqualified for wading reliability at the second preset depth.

The vehicle under test is placed on the sliding module, placing the sliding module, the adjustable water pump, and the vehicle under test in multiple different preset test states to conduct wading tests. In this invention, by adjusting the different preset test states of the sliding module, the adjustable water pump, and the vehicle under test, wading passability and wading reliability tests are conducted on the vehicle under test. This quantifies the vehicle's power performance during wading, obtains the power margin when the vehicle passes through a preset depth, and the power parameters when it fails to pass, ensuring the accuracy of the vehicle wading test device.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] This invention provides a vehicle wading test device that can solve the technical problem that related technologies can only qualitatively determine whether a vehicle can pass through water, and it is difficult to quantitatively evaluate the vehicle's power performance when wading.

[0015] See Figure 1 As shown in the figure, an embodiment of the present invention provides a vehicle wading test device, including a test pool 1, a sliding module 2, a tensile testing component 3, and an adjustable water pump 4. The test pool 1 is used to contain test water. The sliding module 2 is located at the bottom of the test pool 1. The tensile testing component 3 is connected to the vehicle under test 5 and the test pool 1. The adjustable water pump 4 is positioned facing the front of the vehicle under test 5. The vehicle under test 5 is placed on the sliding module, so that the sliding module 2, the adjustable water pump 4, and the vehicle under test 5 are in multiple different preset test states to conduct a wading test on the vehicle under test 5. In this embodiment of the present invention, by adjusting the different preset test states of the sliding module 2, the adjustable water pump 4, and the vehicle under test 5, a wading passability test and a wading reliability test are conducted on the vehicle under test 5. This allows for the quantification of the power performance of the vehicle under test when wading, obtaining the power margin when the vehicle under test passes through at a preset depth and the power parameters when it fails to pass, ensuring the accuracy of the vehicle wading test device.

[0016] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, the sliding module 2 is equipped with four pulley groups 21, each pulley group 21 being positioned below one wheel 51 of the vehicle under test 5. In this embodiment of the invention, each pulley group 21 can be independently locked and unlocked, facilitating accurate simulation of different adhesion conditions encountered by the vehicle under test 5 when wading through water. The locked state can reproduce high adhesion conditions, while the unlocked state can simulate single-wheel or cross-axle slippage caused by low adhesion surfaces such as silt and gravel. This not only tests the wading limit of the vehicle under test 5 under ideal conditions but also facilitates the evaluation of the vehicle under test 5's dynamic performance under real complex road conditions, such as partial wheel slippage, ensuring the reliability and flexibility of the wading test device.

[0017] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1As shown, a water immersion detection component 6 is also provided, which is located inside the vehicle 5 to be tested. The water immersion test device includes the water immersion detection component 6, which changes color at the point of contact with water. In this embodiment of the invention, there are multiple water immersion detection components 6, which are respectively installed in key components such as the battery pack, motor, and wiring harness in the vehicle 5 to be tested. The vehicle 5 to be tested is placed on the sliding module 2 in the test pool, and the water immersion depth is adjusted to a preset depth. After the preset immersion time is reached, the water is drained and the device is left to stand for 12-13 hours. The color change of the water immersion detection component 6 is recorded to obtain the water immersion sealing performance of the corresponding device. The operation is simple.

[0018] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, a remote control module 7 is also provided. The remote control module 7 includes a data acquisition unit 71 and a wireless remote control unit 72, which is wirelessly connected to the data acquisition unit 71. In this embodiment of the invention, the data acquisition unit 71 is an OBD data acquisition unit, which acquires key CAN bus data such as engine speed, torque output, and wheel speed of the vehicle under test 5 in real time through the OBD interface, i.e., the vehicle standard diagnostic interface, providing accurate monitoring of the power system operating conditions. The wireless remote control unit 72 enables unmanned testing by remotely controlling the throttle, brake, and start-stop operations, and is equipped with an emergency stop switch to ensure the safety of the wading test. This ensures that the wading test process avoids the variable interference caused by driver operation, and can completely record the dynamic performance parameters of the vehicle under test 5 when wading, greatly improving the objectivity and repeatability of the test data and ensuring a leapfrog improvement from qualitative judgment to quantitative analysis in wading tests.

[0019] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, a flow velocity sensor 8 is also provided, which is located at the front of the vehicle 5 to be tested. In this embodiment of the invention, the adjustable water pump 4 controls the water flow velocity through adjustable power output, and the flow velocity sensor 8 monitors the water flow velocity in real time and provides feedback, so that the water flow velocity is stably maintained at the set value during the wading test, ensuring the realism of the environmental simulation and the validity of the data in the wading test.

[0020] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, a plurality of waterproof monitoring components 9 are also provided, which are spaced apart and rotatably disposed inside the vehicle 5 to be tested. In this embodiment of the invention, the waterproof monitoring components 9 monitor the water ingress of key areas inside the vehicle 5 from multiple perspectives in real time and record abnormal water seepage paths, thereby improving the reliability of the water wading test device.

[0021] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1As shown, the process involves placing the vehicle under test 5 on the sliding module 2, placing the sliding module 2, the adjustable water pump 4, and the vehicle under test 5 in multiple different preset test states to conduct a wading test on the vehicle under test 5. This includes placing the vehicle under test 5 on the sliding module 2 and locking the sliding module 2 to simulate a high adhesion condition, adjusting the water depth of the test pool 1 to a first preset depth, connecting the vehicle under test 5 and the test pool 1 using the connecting rope 31 in the tensile testing component 3, connecting the tensile gauge 32 in the tensile testing component 3 to the rear of the vehicle under test 5, and adjusting the horizontal position and vertical height of the tensile gauge 32 to position the tensile gauge 32 at the centerline of the vehicle under test 5 and at the same height as the connecting ring 52 at the rear of the vehicle under test 5. This ensures that the connecting ring 52 and the tensile gauge 32 are horizontally connected, preventing the vehicle under test 5 from deflecting or skidding due to uneven force, ensuring that the tensile force measurement direction is consistent with the driving direction, and avoiding side slippage. To reduce the accuracy of the component force; the water flow rate is controlled by the adjustable water pump 4 to make the water flow rate in the test pool 1 reach the first preset speed, and the dynamic water flow simulates the real river or rainstorm water environment to test the stability of the vehicle in the flowing water; the throttle opening of the test vehicle 5 is gradually increased until the pulling force reaches the maximum value, and the pulling force value during the test is obtained to facilitate the quantification of the power of the test vehicle 5; the average pulling force within the first preset time when the test vehicle 5 slips is calculated to the actual ratio of the weight of the test vehicle 5, and the actual ratio is compared with the standard ratio. If the actual ratio is greater than the standard ratio, the test vehicle 5 passes the test at the first preset depth. If the actual ratio is not greater than the standard ratio, the test vehicle 5 fails the test at the first preset depth. In this embodiment of the invention, the first preset time is 3-4s, and the standard ratio is 5%. That is, if the actual ratio is greater than the standard ratio by 5%, the test vehicle 5 passes the test at the first preset depth.

[0022] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, the tensile testing assembly 3 uses a connecting rope 31 to connect the test vehicle 5 and the test pool 1, and connects the tensile gauge 32 in the tensile testing assembly 3 to the rear of the test vehicle 5. Connecting rings 52 are also provided on both sides of the front and rear of the test vehicle 5. Connecting anchor points 11, corresponding to each connecting ring 52, are provided on the inner wall of the test pool 1. The height of the connecting anchor points 11 is adjusted to match the height of the corresponding connecting ring 52. In this embodiment of the invention, the connecting rings 52 at the front and rear of the test vehicle 5 are horizontally connected to the connecting anchor points 11 on the inner wall of the test pool 1, preventing the test vehicle 5 from tilting due to uneven force, preventing additional torque from interfering with the test data, and improving the accuracy of the wading test.

[0023] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1As shown, the tensile testing assembly 3 uses a connecting rope 31 to connect the test vehicle 5 and the test pool 1, and connects the tensile gauge 32 in the tensile testing assembly 3 to the rear of the test vehicle 5. It also includes placing the tensile gauge 32 inside the test pool 1 and on the central axis of the test vehicle 5, ensuring that the tensile gauge 32 is at the same height as the connecting ring 52; and connecting the tensile gauge 32 to the two connecting rings 52 at the rear of the test vehicle 5. In this embodiment of the invention, placing the tensile gauge 32 on the central axis of the test vehicle 5 and at the same height as the connecting rings 52 ensures that the tensile force measurement direction is consistent with the driving direction of the test vehicle 5, avoiding the influence of lateral force on data accuracy.

[0024] As an optional implementation, in one embodiment of the invention, see [link to relevant documentation]. Figure 1 As shown, placing the vehicle under test 5 on the sliding module 2, so that the sliding module 2, the adjustable water pump 4, and the vehicle under test 5 are in multiple different preset test states to conduct a water wading test on the vehicle under test 5, includes placing the vehicle under test 5 on the sliding module 2, adjusting the water depth of the test pool 1 to a second preset depth; connecting the vehicle under test 5 and the test pool 1 using the connecting rope 31 in the tensile testing component 3; adjusting the throttle opening of the vehicle under test 5 until the wheels 51 spin and reach a second preset speed. In this embodiment of the invention, the second preset speed is 5-10 km / h; and allowing the wheels 51 to continuously spin for a second preset time. If the vehicle under test 5 maintains normal operation under preset conditions within the second preset time, then the water wading reliability of the vehicle under test 5 at the second preset depth is qualified. If the vehicle under test 5 does not maintain normal operation under preset conditions within the second preset time, then the water wading reliability of the vehicle under test 5 at the second preset depth is unqualified. In this embodiment of the invention, the second preset time is 2-3 hours. If the vehicle maintains normal operation within the second preset time, that is, if the vehicle does not enter water, does not give any warnings, and does not experience any abnormal conditions such as malfunctions, then the water wading reliability of the vehicle to be tested 5 is qualified.
