Description

Technical Field

[0001] The present application relates to the field of vehicle testing technology, and in particular to a vehicle wading test system. Background Art

[0002] The automobile wading test is an important test in the vehicle development process. The test requires the vehicle to pass through a wading pool of specified water depth at a specified speed to verify the vehicle's passing ability and waterproof safety performance during the wading process. The wading test has become a key step in the vehicle development process.

[0003] Most of the existing water wading test systems are to set up a wading pool on the test track to conduct a vehicle wading test to verify the vehicle's waterproof sealing. At present, with the increasingly high requirements for vehicle verification, especially electric vehicles require 100% verification, so the wading pool must ensure the continuity of verification. At present, different models are being verified simultaneously, which requires the wading pool to meet the verification standards of different depths.

[0004] In the existing wading test system, usually only one wading height is set in a wading pool, and the water level of the pool is guaranteed by the overflow port, such as Figure 1 As shown, when the water level of the wading pool 100 is higher than the overflow port 300, the excess water will flow out from the overflow port 300 through the overflow drain pipe 200. In order to meet the waterproof sealing requirements of different models, the industry mostly uses different wading pools for different model tests. In addition, the space of the wading pool is relatively limited. When the car passes through the wading pool, the waves stirred up are relatively large, and it is difficult to arrange the relevant liquid level adjustment device. Once heavy rain or vehicle failure occurs, manual emergency treatment is required, or wading verification is carried out after the risk is eliminated, which greatly affects the rhythm requirements of continuous production of automobiles.

[0042] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0043] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0044] The automobile wading test is an important test in the vehicle development process. The test requires the vehicle to pass through a wading pool of a specified water depth at a specified speed to verify the vehicle's passing ability and waterproof safety performance during the wading process. The wading test has become a key step in the vehicle development process.

[0045] Most of the existing water wading test systems are to set up a wading pool on the test track to conduct a vehicle wading test to verify the vehicle's waterproof sealing. At present, with the increasing requirements for vehicle verification, especially electric vehicles require 100% verification, so the wading pool must ensure the continuity of verification. At present, different models are being verified simultaneously, which requires the wading pool to meet the verification standards of different depths.

[0046] In the existing wading test system, usually only one wading height is set in a wading pool, and the water level of the pool is guaranteed by the overflow port, such as Figure 1 As shown, when the water level of the wading pool 100 is higher than the overflow port 300, the excess water will flow out from the overflow port 300 through the overflow drain pipe 200. In order to meet the waterproof sealing requirements of different models, the industry mostly uses different wading pools for different model tests. In addition, the space of the wading pool is relatively limited. When the car passes through the wading pool, the waves stirred up are relatively large, and it is difficult to arrange the relevant liquid level adjustment device. Once heavy rain or vehicle failure occurs, manual emergency treatment is required, or wading verification is carried out after the risk is eliminated, which greatly affects the rhythm requirements of continuous production of automobiles.

[0047] In response to the above technical problems, the present application provides a vehicle wading test system.

[0048] like Figure 2 As shown, the vehicle wading test system provided in the embodiment of the present application includes a wading pool 1, a water reservoir 2, a connecting pipe 3, a first drainage device 4, a liquid level measuring device 5 and a control device 6.

[0049] The connecting pipe 3 is arranged between the wading pool 1 and the water reservoir 2 , and the wading pool 1 and the water reservoir 2 are connected to each other through the connecting pipe 3 .

[0050] The suction end of the first drainage device 4 is located in the water reservoir 2 , and the first drainage device 4 is used to discharge the water in the water reservoir 2 to the external environment.

[0051] The liquid level measuring device 5 is arranged in the water reservoir 2 and is used to measure the liquid level of the water reservoir 2. The control device 6 is electrically connected to the first drainage device 4 and the liquid level measuring device 5 respectively. The control device 6 is configured to control the working state of the first drainage device 4 according to the liquid level of the water reservoir 2.

[0052] Specifically, the wading test is one of the important tests to evaluate the normal operation and driving ability of the vehicle in a flooded environment. It mainly checks the sealing, electrical safety and waterproof ability of the three-electric system (battery, motor, and electronic control) of the vehicle to ensure that the vehicle can drive normally and operate safely on roads with accumulated water. Among them, the wading pool 1 is used for vehicles to drive through, so as to simulate the scene of the vehicle in a wading environment and verify the waterproof sealing performance of the vehicle.

[0053] like Figure 2 As shown, there is a retaining wall 7 between the wading pool 1 and the water reservoir 2, and the connecting pipe 3 is arranged to penetrate the retaining wall 7, so as to connect the wading pool 1 and the water reservoir 2. According to the principle of communicating vessels, the liquid levels of the wading pool 1 and the water reservoir 2 are the same. Therefore, by setting a liquid level measuring device 5 in the water reservoir 2, the liquid levels of the wading pool 1 and the water reservoir 2 can be measured.

[0054] Since the waves stirred up when a car passes through the wading pool 1 are relatively large, the liquid level measuring device 5 is arranged in the water reservoir 2 with a stable liquid surface to ensure the measurement accuracy of the liquid level measuring device 5 and avoid damage to the liquid level measuring device 5 caused by impact.

[0055] like Figure 2 As shown, the first drainage device 4 includes a first drainage pump 41 and a first drainage pipe 42 . The drainage end of the first drainage pump 41 is connected to the first drainage pipe 42 , so that the water sucked by the suction end of the first drainage pump 41 is discharged to the external environment through the first drainage pipe 42 .

[0056] Compared with the passive drainage method through the overflow drain pipe 200 in the prior art, the vehicle wading test system provided in the embodiment of the present application is provided with a first drainage device 4 that can actively drain water, so that the wading pool 1 can be maintained at any liquid level height when the first drainage device 4 is not started, so that one wading pool 1 can meet the wading depth requirements of different vehicle models, without the need to set up multiple wading pools 1, which helps to save site space and reduce test costs.

[0057] Furthermore, since the suction end of the first drainage device 4 is located in the water reservoir 2, the first drainage device 4 will not collide or be released from the car, and the waves stirred up when the car passes through the wading pool 1 will not cause impact on the first drainage device 4, which is beneficial to improving the service life of the first drainage device 4.

[0058] Exemplarily, the control device 6 is an automatic distribution box equipped with intelligent devices such as a programmable logic controller. The control device 6 can accurately adjust and control the electronic components of the vehicle wading test system according to preset programs or external signals, and can also monitor the liquid level of the wading pool 1 in real time through the liquid level measuring device 5.

[0059] For example, when the liquid level in the wading pool 1 rises excessively due to heavy rain or other reasons, the liquid level measuring device 5 sends a liquid level signal to the control device 6. After receiving the liquid level signal, the control device 6 sends a drainage signal to the first drainage device 4. After receiving the drainage signal, the first drainage device 4 starts to discharge the water in the water reservoir 2 to the external environment until the liquid levels in the water reservoir 2 and the wading pool 1 drop to a specific height, thereby ensuring the continuity of the vehicle's waterproof sealing test.

[0060] The vehicle wading test system provided in the embodiment of the present application has a wading pool 1 and a water reservoir 2 that are interconnected through a connecting pipe 3. Therefore, according to the communicating vessel principle, the liquid levels of the wading pool 1 and the water reservoir 2 are the same. By arranging a liquid level measuring device 5 in the water reservoir 2, the liquid levels of the wading pool 1 and the water reservoir 2 can be obtained, ensuring that the wading pool 1 meets the wading height requirements of different vehicle models; and, since the vehicle only passes through the wading pool 1, the liquid level of the water reservoir 2 is more stable, ensuring the measurement accuracy of the liquid level measuring device 5, and preventing the liquid level measuring device 5 from being damaged by impact; by arranging a control device 6 that is electrically connected to the first drainage device 4 and the liquid level measuring device 5, respectively, the liquid level of the wading pool 1 can be accurately adjusted by using the control device 6 according to the liquid level information of the water reservoir 2, which not only meets the wading height requirements of different vehicle models, but also can quickly drain water in scenarios such as heavy rain or vehicle failure, eliminating safety hazards during the test.

[0061] In a specific embodiment, the bottom surface of the connecting pipe 3 is lower than or flush with the bottom wall of the wading pool 1 .

[0062] For example, Figure 2 As shown, the bottom surface of the connecting pipe 3 contacts the bottom wall of the wading pool 1 , and the depth of the bottom surface of the connecting pipe 3 is the same as the depth of the bottom wall of the wading pool 1 .

[0063] Through this arrangement, while ensuring that the liquid levels of the water reservoir 2 and the wading pool 1 are consistent, it can also ensure that the water at the bottom of the wading pool 1 can be discharged to the external environment.

[0064] In a further embodiment, the bottom wall of the water reservoir 2 is at least partially lower than the bottom wall of the wading pool 1 .

[0065] like Figure 2 As shown, the water reservoir 2 includes a buffer portion 21 and a water storage portion 22 which are interconnected. The buffer portion 21 is closer to the wading pool 1 than the water storage portion 22. The bottom wall of the buffer portion 21 is slightly lower than the bottom wall of the water reservoir 2, and the bottom wall of the water storage portion 22 is lower than the bottom wall of the buffer portion 21. That is, the bottom wall of the water reservoir 2 is stepped, and the maximum depth of the bottom wall of the water storage portion 22 is greater than the depth of the wading pool 1.

[0066] Through this arrangement, when the wading pool 1 needs to be emptied, the water in the wading pool 1 can be fully drained to avoid excess water remaining at the bottom of the wading pool 1.

[0067] In one embodiment, the vehicle wading test system further includes a terminal device 10 , which is communicatively connected to the control device 6 , and is used to send control instructions to the control device 6 .

[0068] The terminal device 10 may be a computer terminal, an industrial control terminal, a mobile terminal, etc.

[0069] Exemplarily, the terminal device 10 has a display screen module, and the tester can view the measurement results, working status, etc. of the liquid level measuring device 5, the first drainage device 4 and other devices on the terminal device 10. The tester can also perform operations on the terminal device 10 to send control instructions to the control device 6, so that the control device 6 controls the working status of the first drainage device 4 and other devices.

[0070] Optionally, the communication connection between the terminal device 10 and the control device 6 may be a wired communication connection or a wireless communication connection.

[0071] In this embodiment, by setting up a communication connection between the terminal device 10 and the control device 6, the tester can issue control instructions to the control device 6 through the terminal device 10, thereby improving the intelligence and automation of the vehicle wading test system.

[0072] In a further embodiment, the terminal device 10 is a mobile electronic device, and the terminal device 10 is wirelessly connected to the control device 6 .

[0073] Exemplarily, the terminal device 10 is a mobile electronic device such as a smart phone, a tablet computer, or a laptop computer, and the terminal device 10 performs data transmission via Bluetooth technology or IEEE 802.11 or the like.

[0074] For example Figure 3 As shown, the control device 6 has a Bluetooth module 61 and a microcontroller development board 62. The control device 6 is wirelessly connected to the terminal device 10 via the Bluetooth module 61. The Bluetooth module 61 is electrically connected to the microcontroller development board 62. The microcontroller development board 62 is electrically connected to the first drainage device 4 and other functional devices. After the terminal device 10 sends a control instruction to the Bluetooth module 61, the Bluetooth module 61 transmits the control instruction to the microcontroller development board 62, and the microcontroller development board 62 drives the first drainage device 4 and other functional devices through a program.

[0075] In this embodiment, by setting up a wireless communication connection between the terminal device 10 and the control device 6, the flexibility and intelligence of the vehicle wading test system are improved, the arrangement of connecting cables is omitted, and it is beneficial to save occupied space.

[0076] In one embodiment, the vehicle wading test system also includes a second drainage device 8, the suction end of the second drainage device 8 is located in the water reservoir 2, the second drainage device 8 is used to discharge the water in the water reservoir 2 to the external environment, the rated power of the second drainage device 8 is greater than the rated power of the first drainage device 4, and the second drainage device 8 is electrically connected to the control device 6.

[0077] Exemplarily, the rated power of the second drainage device 8 is 5 to 10 times the rated power of the first drainage device 4 , and the second drainage device 8 can drain all the accumulated water in the wading pool 1 within 15 minutes.

[0078] The second drainage device 8 is used to quickly control the liquid level of the wading pool 1 or drain the water in the wading pool 1 in an emergency situation to ensure the continuity of the automobile production test. The emergency situation may include heavy rain, vehicle failure and other scenes.

[0079] like Figure 2 As shown, the second drainage device 8 includes a second drainage pump 81 and a second drainage pipe 82 , and the drainage end of the second drainage pump 81 is connected to the second drainage pipe 82 , so that the water sucked by the suction end of the second drainage pump 81 is discharged to the external environment through the second drainage pipe 82 .

[0080] Alternatively, if Figure 2 As shown, the suction end of the second drainage pump 81 is located in the water storage part 22, and the suction end of the second drainage pump 81 is lower than the bottom wall of the buffer part 21. Through this arrangement, the second drainage device 8 can be used to fully drain the water in the wading pool 1.

[0081] Optionally, the diameter of the second drainage pipe 82 is greater than the diameter of the first drainage pipe 42, thereby increasing the drainage volume and drainage speed of the second drainage device 8 per unit time.

[0082] In this embodiment, by providing the second drainage device 8, rapid drainage of the wading pool 1 in an emergency situation is achieved, and the liquid level of the wading pool 1 can be quickly controlled or the water in the wading pool 1 can be discharged to ensure the continuity of the automobile production test.

[0083] In a further embodiment, the control instruction includes an emergency drainage instruction, and the emergency drainage instruction is used to instruct the control device 6 to control the second drainage device 8 to operate.

[0084] Specifically, in emergency situations such as heavy rain or a vehicle wading failure, the tester operates on the terminal device 10 to issue an emergency drainage instruction to the control device 6, so that the control device 6 controls the operation of the second drainage device 8 to quickly adjust the liquid level in the wading pool 1 or empty the wading pool 1.

[0085] In one embodiment, the vehicle wading test system further includes a water replenishing device 9 , which is electrically connected to the control device 6 , and is used to drain water into the water reservoir 2 .

[0086] like Figure 2 As shown, the water replenishment device 9 includes a water replenishment pipe 91 and a water replenishment electric valve 92. One end of the water replenishment pipe 91 is located in the water reservoir 2, and the other end is connected to the water source of the external environment. The water replenishment electric valve 92 is connected to the water replenishment pipe 91.

[0087] The control device 6 can control the water replenishment electric valve 92 to open or close. When the water replenishment electric valve 92 is open, water from the external environment can flow into the water reservoir 2 through the water replenishment pipe 91; when the water replenishment electric valve 92 is closed, water from the external environment stops draining into the water reservoir 2.

[0088] In this embodiment, the control device 6 can control the drainage of the wading pool 1 through the first drainage device 4 and the second drainage device 8, and can also control the water inlet of the wading pool 1 through the water replenishment device 9, which is conducive to more accurate control of the liquid level height of the wading pool 1.

[0089] In one embodiment, the vehicle wading test system has a first vehicle model mode and a second vehicle model mode.

[0090] In the first vehicle model mode, the control device 6 controls the working state of the first drainage device 4, the second drainage device 8 or the water replenishing device 9 so that the liquid level of the water reservoir 2 is in the first liquid level range.

[0091] In the second vehicle model mode, the control device 6 controls the working state of the first drainage device 4, the second drainage device 8 or the water replenishing device 9 so that the liquid level of the water reservoir 2 is in the second liquid level range.

[0092] Different vehicle models have different wading depths. The first vehicle model mode and the second vehicle model mode correspond to different vehicle models and wading depths, so that the vehicle wading test system can meet the wading depth requirements of various vehicle models. Of course, the vehicle wading test system can also have a third vehicle model mode, a fourth vehicle model mode, etc. Different vehicle model modes correspond to different liquid level ranges to adapt to more vehicle models.

[0093] Exemplarily, the control device 6 is an automatic distribution box, and a mode switching button is provided in the control device 6, and the tester can change the vehicle model mode through the mode switching button.

[0094] Exemplarily, the first vehicle model mode is applicable to electric sedans, and the first liquid level interval is [200mm, 300mm]; the second vehicle model mode is applicable to electric SUVs (sport utility vehicle or suburban utility vehicle), and the second liquid level interval is [400mm, 500mm].

[0095] For example, the workflow of the vehicle wading test system includes:

[0096] In the first vehicle model, when the liquid level measuring device 5 measures that the liquid level is lower than 300 mm, the control device 6 controls the water replenishment electric valve 92 to open according to the liquid level signal sent by the liquid level measuring device 5, and the water source in the external environment replenishes water to the water reservoir 2 through the water replenishment pipe 91, so that the liquid level of the wading pool 1 continues to rise. When the liquid level measuring device 5 measures that the liquid level reaches 300 mm, the control device 6 controls the water replenishment electric valve 92 to close according to the liquid level signal sent by the liquid level measuring device 5, stops replenishing water, and ensures that the wading pool 1 meets the wading depth requirements of the electric car.

[0097] In the second vehicle model mode, when the liquid level measuring device 5 measures the liquid level to be lower than 500 mm, the control device 6 controls the water replenishment electric valve 92 to open according to the liquid level signal sent by the liquid level measuring device 5, and the water source in the external environment replenishes water to the water reservoir 2 through the water replenishment pipe 91, so that the liquid level of the wading pool 1 continues to rise. When the liquid level measuring device 5 measures the liquid level to reach 500 mm, the control device 6 controls the water replenishment electric valve 92 to close according to the liquid level signal sent by the liquid level measuring device 5, stops replenishing water, and ensures that the wading pool 1 meets the wading depth requirements of the electric SUV.

[0098] During the rainy season, the liquid level in the wading pool 1 rises rapidly, causing the liquid level in the water reservoir 2 to also rise rapidly. The liquid level measuring device 5 measures that the liquid level is higher than the upper limit of the liquid level. The control device 6 controls the operation of the first drainage device 4 according to the liquid level signal sent by the liquid level measuring device 5, so that the water reservoir 2 is quickly drained and the liquid level continues to drop. When the liquid level measuring device 5 measures that the liquid level is lower than the lower limit of the liquid level, the control device 6 controls the first drainage device 4 to stop operating according to the liquid level signal sent by the liquid level measuring device 5. Among them, the upper and lower limits of the liquid level can be the upper and lower limits of the liquid level range of the current vehicle model mode, or they can be separately set upper and lower limits of the safety liquid level, which are not specifically limited in this application.

[0099] When a vehicle wading failure occurs, the tester can use the terminal device 10 to connect to the Bluetooth module 61 of the control device 6 and send an emergency drainage command to the control device 6. After receiving the emergency drainage command, the control device 6 controls the second drainage device 8 to operate and drain the water in the reservoir 2 within 15 minutes through the second drainage pipe 82. After the water in the reservoir 2 is drained, the water in the wading pool 1 is also drained accordingly. When the liquid level measuring device 5 measures that the liquid level is lower than the lower limit of the liquid level, the control device 6 controls the second drainage device 8 to stop operating.

[0100] In a further embodiment, the control instruction further includes a first vehicle model instruction and a second vehicle model instruction, the first vehicle model instruction is used to instruct the control device 6 to switch to the first vehicle model mode, and the second vehicle model instruction is used to instruct the control device 6 to switch to the second vehicle model mode.

[0101] Specifically, the tester can operate on the terminal device 10 to send a first vehicle model instruction or a second vehicle model instruction to the control device 6, so that after receiving the first vehicle model instruction or the second vehicle model instruction, the control device 6 controls the liquid level of the wading pool 1 within the corresponding liquid level range, thereby improving the flexibility and operational convenience of the vehicle wading test system.
