Technical Field
[0001] This disclosure belongs to the field of automotive testing technology, and specifically relates to a vehicle wading test system. Background Technology
[0002] The vehicle wading test is an important test in the vehicle development process. The test requires the vehicle to pass through a wading pool at a certain speed to verify the vehicle's waterproof sealing performance.
[0003] Wading pools are typically installed on test tracks in vehicle manufacturing plants. Water supply pipes and overflow pipes are installed on the sides of the wading pools. When the actual water level in the wading pool is higher than the preset level, excess water in the wading pool flows out through the overflow pipe. When the actual water level in the wading pool is lower than the preset level, water supply pipes replenish water into the wading pool, thereby maintaining the water level in the wading pool at the preset level.
[0004] However, different vehicles require different wading depths for wading tests, and wading pools are usually only suitable for one type of vehicle and not for other types of vehicles, thus having a narrow scope of application. Summary of the Invention
[0005] This disclosure provides a vehicle wading test system that solves the technical problems existing in related technologies. The technical solution is as follows: This disclosure provides a vehicle wading test system, which includes a wading pool, a drive assembly, a lifting platform, and a controller. The liquid level in the wading pool is maintained at a preset height; The drive assembly is located at the edge of the wading pool; The lifting platform is positioned below the liquid surface in the wading pool and is connected to the drive assembly. The lifting platform is used for the test vehicle to drive, and a wading depth is formed between the lifting platform and the liquid surface of the wading pool. The controller is electrically connected to the drive assembly, and the controller controls the drive assembly to drive the lifting platform to rise and fall, thereby adjusting the wading depth.
[0006] In some possible implementations, the drive assembly includes a plurality of drive mechanisms, all of which are electrically connected to the controller; The lifting platform includes multiple lifting plates, which are arranged sequentially along the extension direction of the wading pool, and each lifting plate is connected to at least one of the driving mechanisms.
[0007] In some possible implementations, the drive mechanism is connected to both sides of each of the lifting plates.
[0008] In some possible implementations, the drive mechanism includes a drive component and a connecting component; The driving component is disposed at the edge of the wading pool; The connector is connected to both the drive unit and the lifting plate, and the connector drives the lifting plate to move up and down under the drive of the drive unit.
[0009] In some possible implementations, the drive mechanism further includes a limiting element; The limiting member is disposed on the side inside the wading pool. The limiting member is connected to the connecting member and is used to restrict the lateral movement of the connecting member.
[0010] In some possible implementations, the limiting member has a limiting track that extends along the depth direction of the wading pool; The driving mechanism also includes a limiting wheel, which is rotatably connected to the connecting member. The limiting wheel is embedded in the limiting track and can roll along the limiting track.
[0011] In some possible implementations, the vehicle wading test system also includes a fence connected to both sides of the lifting platform.
[0012] In some possible implementations, the vehicle wading test system further includes a transition plate, a first end of which is rotatably connected to the lifting platform, and a second end of which is slidably connected to the bottom of the wading pool. The transition plate allows the test vehicle to travel to the lifting platform, wherein the height difference between the first end and the liquid surface of the wading pool is greater than the height difference between the second end and the liquid surface of the wading pool.
[0013] In some possible implementations, the vehicle wading test system further includes a water supply pipe and an overflow pipe, which are installed in the wading pool.
[0014] In some possible implementations, the controller controls the drive assembly to raise and lower the lifting platform according to the type of the test vehicle.
[0015] The technical solution provided in this disclosure includes at least the following beneficial effects: The vehicle wading test system disclosed herein establishes a wading height between the lifting platform and the liquid surface of the wading pool. The controller controls the drive assembly to raise and lower the lifting platform below the liquid surface of the wading pool. The height difference between the lifting platform and the liquid surface can be adjusted, thus adjusting the wading height. This allows the wading pool to be suitable for wading tests of different types of vehicle models, thereby improving the applicability of the wading pool.

[0022] Vehicle wading test is a crucial part of the vehicle development process. This test requires the vehicle to pass through a wading pool at a specific speed to verify its waterproofing performance. Wading pools are typically equipped with a water inlet pipe and an overflow pipe. The overflow pipe's installation height roughly determines the preset water level in the wading pool, which is the wading depth the vehicle will traverse. The overflow pipe is normally open, while the water inlet pipe can switch between closed and open states. When the actual water level in the wading pool is higher than the preset level, the water inlet pipe closes, allowing excess water to drain out through the overflow pipe, gradually lowering the water level to the preset level. Conversely, when the actual water level is lower than the preset level, the water inlet pipe opens to replenish water, gradually raising the water level to the preset level before closing again. Therefore, the water inlet pipe and overflow pipe effectively maintain the water level in the wading pool at the preset level.
[0023] However, different vehicles require different wading depths for wading tests. For example, the wading depth for sedans is less than that for MPVs (Multi-Purpose Vehicles), the wading depth for MPVs is roughly equal to that for SUVs (Sport Utility Vehicles), and the wading depth for SUVs is less than that for off-road vehicles. Since the water level in the wading pool is maintained at a preset height, meaning the water level remains roughly constant, the wading pool is only suitable for one type of vehicle and not for other types of vehicles. This limits the applicability of the wading pool.
[0024] This disclosure provides a vehicle wading test system 1. (See also...) Figure 1 The vehicle wading test system 1 includes a wading pool 10, a drive assembly 11, a lifting platform 12, and a controller (not shown in the figure). The liquid level in the wading pool 10 is maintained at a preset height. The drive assembly 11 is located at the edge of the wading pool 10. The lifting platform 12 is located below the liquid level in the wading pool 10 and is connected to the drive assembly 11. The lifting platform 12 is used for the test vehicle to drive, and a wading depth is formed between the lifting platform 12 and the liquid level in the wading pool 10. The controller is electrically connected to the drive assembly 11, and the controller controls the drive assembly 11 to drive the lifting platform 12 to rise and fall, thereby adjusting the wading depth.
[0025] The test vehicle undergoes a water wading test by traveling at a certain speed on the lifting platform 12. It can be understood that the wading height of the test vehicle is the height between the upper surface of the lifting platform 12 and the liquid surface in the wading pool 10 when the test vehicle is traveling on the lifting platform 12.
[0026] By adopting the technical solution of this disclosure embodiment, since the test vehicle travels on the lifting platform 12 when conducting the water wading test, a wading height is formed between the lifting platform 12 and the liquid surface of the wading pool 10. The controller controls the drive component 11 to drive the lifting platform 12 to rise and fall below the liquid surface of the wading pool 10, which can adjust the height difference between the lifting platform 12 and the liquid surface, that is, adjust the wading height, so that the wading pool 10 can be used for water wading tests of different types of vehicles, thereby improving the applicability of the wading pool 10.
[0027] For example, refer to Figure 1 The initial position of the lifting platform 12 can be at the bottom of the wading pool 10 and abut against the bottom wall of the wading pool 10.
[0028] When the test vehicle is an off-road vehicle, the lifting platform 12 can remain in its initial position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the off-road vehicle. The actual wading depth of the off-road vehicle when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the off-road vehicle.
[0029] refer to Figure 2 When the test vehicle is an SUV or MPV, the controller can control the drive component 11 to drive the lifting platform 12 to rise from the initial position to the first position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the SUV or MPV. The actual wading depth of the SUV or MPV when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the SUV or MPV.
[0030] refer to Figure 3 When the test vehicle is a sedan, the controller can control the drive assembly 11 to raise the lifting platform 12 from the initial position to a second height. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the sedan. The actual wading depth of the sedan when driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the sedan. The second height can be greater than the first height.
[0031] After the test vehicle completes the test, the controller can control the drive assembly 11 to drive the lifting platform 12 to reset to the initial position.
[0032] Furthermore, in related technologies, when the test vehicle has poor waterproof sealing, it may become stuck while driving in the wading pool 10, meaning it cannot continue driving. Since the lower part of the test vehicle is below the water surface, it is usually necessary to drain the water from the wading pool 10 before removing the test vehicle. After removing the test vehicle, water needs to be pumped back into the wading pool 10 before the next test vehicle can be tested, which is time-consuming. In the technical solution disclosed in this invention, even if the vehicle fails the wading test and stops on the lifting platform 12, the controller can control the drive assembly 11 to raise the lifting platform 12 above the water surface of the wading pool 10, exposing the test vehicle and facilitating its removal by staff. This also eliminates the need to drain the water from the wading pool 10, reducing the time required. After removing the test vehicle, the controller can drive the drive assembly 11 to reset the lifting platform 12 to its initial position for the next wading test.
[0033] In some possible implementations, refer to Figure 4 The vehicle wading test system 1 also includes a water supply pipe 15 and an overflow pipe 16, which are installed in the wading pool 10.
[0034] The water supply pipe 15 can switch between a closed state and an open state, while the overflow pipe 16 is kept in a normally open state. The water supply pipe 15 and the overflow pipe 16 can ensure that the liquid level in the wading pool 10 is maintained at a preset height.
[0035] Specifically, when the actual height of the liquid level in the wading pool 10 is lower than the preset height, the water supply pipe 15 switches to the open state to replenish water into the wading pool 10, and the liquid level in the wading pool 10 gradually rises to the preset height, after which the water supply pipe 15 switches to the closed state; when the actual height of the liquid level in the wading pool 10 is higher than the preset height, the water supply pipe 15 switches to the closed state, and the excess water in the wading pool 10 flows out through the overflow pipe 16, and the liquid level in the wading pool 10 gradually drops to the preset height.
[0036] In some possible implementations, refer to Figure 5 The wading pool 10 typically includes a first ramp 100, a test ramp 101 and a second ramp 102 connected in sequence. The end of the first ramp 100 connected to the test ramp 101 is lower than the other end of the first ramp 100. Similarly, the end of the second ramp 102 connected to the test ramp 101 is lower than the other end of the second ramp 102. The lifting platform 12 is located on the test ramp 101.
[0037] The test vehicle enters from the end of the first ramp 100 away from the test track 101, passes through the first ramp 100, the test track 101 and the second ramp 102 in sequence, and then exits from the end of the second ramp 102 away from the test track 101.
[0038] In some possible implementations, refer to Figure 6 The vehicle wading test system 1 also includes a transition plate 14. The first end 141 of the transition plate 14 is rotatably connected to the lifting platform 12, and the second end 142 of the transition plate 14 is slidably connected to the bottom of the wading pool 10. The transition plate 14 is used for the test vehicle to drive to the lifting platform 12. The height difference between the first end 141 and the liquid surface of the wading pool 10 is greater than the height difference between the second end 142 and the liquid surface of the wading pool 10.
[0039] Understandably, when the lifting platform 12 is raised, it is not connected to either the first ramp 100 or the second ramp 102, making it inconvenient for test vehicles to travel from the first ramp 100 to the lifting platform 12, or from the lifting platform 12 to the second ramp 102. To improve this, this embodiment of the present disclosure provides a transition plate 14. The first end 141 of the transition plate 14 is rotatably connected to the end of the lifting platform 12, and the second end 142 of the transition plate 14 is slidably connected to the bottom of the pool (the first ramp 100 or the second ramp 102). When the lifting platform 12 is raised, the test vehicle can travel from the first ramp 100 to the lifting platform 12 via the transition plate 14, and can also travel from the lifting platform 12 to the second ramp 102 via the transition plate 14.
[0040] The height difference between the first end 141 and the liquid surface of the wading pool 10 is greater than the height difference between the second end 142 and the liquid surface of the wading pool 10, so as to avoid the wading depth of the vehicle traveling on the transition plate 14 being greater than the wading depth traveling on the lifting platform 12, thus ensuring the accuracy of the test results.
[0041] In some possible implementations, refer to Figure 1 The drive assembly 11 includes multiple drive mechanisms 110, all of which are electrically connected to the controller. The lifting platform 12 includes multiple lifting plates 120, which are arranged sequentially along the extension direction of the wading pool 10, and each lifting plate 120 is connected to at least one drive mechanism 110.
[0042] The controller can simultaneously control multiple drive mechanisms 110 to drive their respective connected lifting plates 120 to rise and fall synchronously, so as to ensure that the multiple drive mechanisms 110 work synchronously and drive the multiple lifting plates 120 to be at the same height as much as possible.
[0043] The heavy lifting platform 12 is divided into multiple lighter lifting plates 120. Each lifting plate 120 is connected to at least one drive mechanism 110. In other words, the weight of the lifting platform 12 is shared by multiple drive mechanisms 110, thereby reducing the power output required by the drive mechanism 110 when driving the lifting plate 120 to rise and fall.
[0044] In some possible implementations, two adjacent lifting plates 120 may be hinged together.
[0045] It is understandable that each lifting plate 120 is driven independently by its corresponding drive mechanism 110. Due to manufacturing errors, after multiple lifting operations, the drive mechanism 110 may cause a height difference between adjacent lifting plates 120. Therefore, adjacent lifting plates 120 can be hinged together to limit the height difference caused by errors, thus keeping it within a certain range and preventing excessive height differences between them.
[0046] In some possible implementations, refer to Figure 1 Each lifting plate 120 has a drive mechanism 110 connected to both sides.
[0047] With drive mechanisms 110 connected to both sides of the lifting plate 120, meaning each lifting plate 120 is connected to at least two drive mechanisms 110, the power output required by the drive mechanisms 110 when driving the lifting plate 120 to rise and fall can be further reduced. Furthermore, connecting drive mechanisms 110 to both sides of the lifting plate 120 can balance the forces on the lifting plate 120 and prevent it from deflecting.
[0048] For example, the lifting plate 120 is a square plate, and each of the four corners of the lifting plate 120 is connected to a drive mechanism 110. Of course, there are other ways in which the drive mechanism 110 is connected to the lifting plate 120, which are not limited here.
[0049] In some possible implementations, refer to Figure 1 The drive mechanism 110 includes a drive component 1100 and a connecting component. The drive component 1100 is located at the edge of the wading pool 10. The connecting component is connected to both the drive component 1100 and the lifting plate 120, and the connecting component drives the lifting plate 120 to rise and fall under the drive of the drive component 1100.
[0050] The drive component 1100 can be a hydraulic cylinder or other drive components, which are not limited here.
[0051] By placing the drive unit 1100 on the edge of the wading pool 10 and connecting it with a connector, it is possible to prevent the drive unit 1100 from coming into contact with the water in the wading pool 10, thereby preventing damage to the drive unit 1100.
[0052] In one example, reference Figure 1 The connector may have a first connecting part and a second connecting part 1101b connected together. The first connecting part extends along the depth direction of the wading pool 10 and is connected to the lifting plate 120. The second connecting part 1101b extends laterally and is connected to the driving member 1100.
[0053] The first connecting part and the second connecting part 1101b can prevent the connecting part from interfering with the side wall of the wading pool 10 during the process of raising and lowering the lifting plate 120, thereby avoiding damage to the connecting part.
[0054] In some possible implementations, the vehicle wading system further includes multiple height detectors (not shown in the figure), each height detector corresponding to and detecting the driving height of multiple drive components 1100. All height detectors are electrically connected to a controller, which controls all drive components 1100 to stop operating when the difference between the driving heights measured by at least two height detectors exceeds a preset difference.
[0055] The driving height refers to the height difference between the current position of the moving part of the driving component 1100 and its initial position. It can be understood that the moving part of the driving component 1100 is connected to the connecting member; the movement of the moving part causes the connecting member to move up and down, thereby causing the lifting plate 120 to move up and down. When the moving part of the driving component 1100 is in its initial position, the corresponding lifting plate 120 is also in its initial position, meaning the corresponding lifting plate 120 is in contact with the bottom wall of the wading pool 10. When there is a certain height difference between the current position of the moving part of the driving component 1100 and its initial position, the current position of the corresponding lifting plate 120 will have the same height difference as its initial position. Therefore, by detecting the driving height of the moving part, the height difference between the current position of the lifting plate 120 and its initial position can be indirectly obtained.
[0056] When the difference between the driving heights of the corresponding drive components 1100 measured by at least two height detectors is greater than the preset difference, it indicates that the height difference between the positions of the lifting plates 120 corresponding to the at least two height detectors is too large, which may cause significant interference to the results of the water wading test of the test vehicle and cannot guarantee the accuracy of the water wading test results of the test vehicle. It is necessary to stop the corresponding drive components 1100 for maintenance and then re-perform the water wading test of the test vehicle after maintenance.
[0057] In some possible implementations, refer to Figure 1 The drive mechanism 110 also includes a limiting member 1102. The limiting member 1102 is disposed on the side inside the wading pool 10, and is connected to the connecting member, and is used to limit the lateral movement of the connecting member.
[0058] The limiting member 1102 is located on the side of the wading pool 10 and is spaced apart from the lifting plate 120.
[0059] The connector is connected to the limiting member 1102, which restricts the lateral movement of the connector while allowing the connector to move along the depth direction of the wading pool 10 to prevent the connector from tilting, thereby preventing the lifting plate 120 from tilting.
[0060] In some possible implementations, the limiting member 1102 has a limiting track (not shown in the figure) that extends along the depth direction of the wading pool 10. The drive mechanism 110 also includes a limiting wheel (not shown in the figure) that is rotatably connected to the connecting member, is embedded in the limiting track, and can roll along the limiting track.
[0061] The limiting wheel is rotatably connected to the connecting piece and can rotate relative to the connecting piece. When the driving component 1100 drives the connecting piece to rise and fall, the limiting wheel can roll along the limiting track, so that the connecting piece is limited by the limiting track, while reducing the friction between the connecting piece and the limiting track, and improving the smoothness of the moving of the connecting piece relative to the limiting track.
[0062] In some possible implementations, refer to Figure 1 The vehicle wading test system 1 also includes a fence 13, which is connected to both sides of the lifting platform 12.
[0063] Fences 13 are installed on both sides of the lifting platform 12 to prevent vehicles from colliding directly with the side walls of the wading pool 10 in abnormal situations, thus protecting the vehicles and the wading pool 10.
[0064] In some possible implementations, the controller controls the drive assembly 11 to drive the lifting platform 12 to rise and fall according to the type of test vehicle.
[0065] The controller can control the drive assembly 11 to drive the lifting platform 12 to rise and fall according to the type of test vehicle, so that the height difference between the lifting platform 12 and the liquid surface is approximately equal to the wading height of the test vehicle.
[0066] For example, the initial position of the lifting platform 12 can be at the bottom of the wading pool 10 and abut against the bottom wall of the wading pool 10.
[0067] When the test vehicle is detected to be an off-road vehicle, the lifting platform 12 can remain in its initial position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the off-road vehicle. The actual wading depth of the off-road vehicle when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the off-road vehicle.
[0068] When the test vehicle is detected to be an SUV or MPV, the controller can control the drive assembly 11 to drive the lifting platform 12 to rise from the initial position to the first position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the SUV or MPV. The actual wading depth of the SUV or MPV when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the SUV or MPV.
[0069] When the test vehicle is detected to be a sedan, the controller can control the drive assembly 11 to raise the lifting platform 12 from the initial position to a second height. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the sedan. The actual wading depth of the sedan when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the sedan. The second height can be greater than the first height.
[0070] After the test vehicle completes the test, the controller can control the drive assembly 11 to drive the lifting platform 12 to reset to the initial position.
[0071] In some possible implementations, the vehicle wading test system 1 also includes a vision sensor electrically connected to a controller, which controls the drive assembly 11 to drive the lifting platform 12 to rise and fall based on the type of test vehicle detected by the vision sensor.
[0072] For example, the initial position of the lifting platform 12 can be at the bottom of the wading pool 10 and abut against the bottom wall of the wading pool 10.
[0073] When the vision sensor detects that the test vehicle is an off-road vehicle, the lifting platform 12 can remain in its initial position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the off-road vehicle. The actual wading depth of the off-road vehicle when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the off-road vehicle.
[0074] When the vision sensor detects that the test vehicle is an SUV or MPV, the controller can control the drive assembly 11 to drive the lifting platform 12 to rise from the initial position to the first position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the SUV or MPV. The actual wading depth of the SUV or MPV when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the SUV or MPV.
[0075] When the vision sensor detects that the test vehicle is a sedan, the controller can control the drive assembly 11 to raise the lifting platform 12 from the initial position to a second height. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the sedan. The actual wading depth of the sedan when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the sedan. The second height can be greater than the first height.
[0076] After the test vehicle completes the test, the controller can control the drive assembly 11 to drive the lifting platform 12 to reset to the initial position.
[0077] In some possible implementations, the vehicle wading test system 1 also includes a barcode scanning component, which is electrically connected to the controller. The barcode scanning component is used to scan the VIN code (Vehicle Identification Number) of the test vehicle to obtain the type of the test vehicle. The controller controls the drive component 11 to drive the lifting platform 12 to rise and fall based on the type of the test vehicle obtained by the barcode scanning component.
[0078] For example, the initial position of the lifting platform 12 can be at the bottom of the wading pool 10 and abut against the bottom wall of the wading pool 10.
[0079] When the scanning component scans the VIN code of the test vehicle and finds that the test vehicle is an off-road vehicle, the lifting platform 12 can remain in its initial position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the off-road vehicle. The actual wading depth of the off-road vehicle when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the off-road vehicle.
[0080] When the scanning component scans the VIN code of the test vehicle and obtains that the test vehicle is an SUV or MPV, the controller can control the drive component 11 to drive the lifting platform 12 to rise from the initial position to the first position. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the SUV or MPV. The actual wading depth of the SUV or MPV when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the SUV or MPV.
[0081] When the scanning component scans the VIN code of the test vehicle and confirms that the test vehicle is a sedan, the controller can control the drive component 11 to raise the lifting platform 12 from the initial position to a second height. At this time, the height difference between the lifting platform 12 and the liquid surface matches the wading depth of the sedan. The actual wading depth of the sedan when it is driving on the lifting platform 12 is approximately equal to the theoretical wading depth of the sedan. The second height can be greater than the first height.
[0082] After the test vehicle completes the test, the controller can control the drive assembly 11 to drive the lifting platform 12 to reset to the initial position.
[0083] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
