Description

Technical Field

[0001] This utility model belongs to the field of vehicle testing technology, and in particular relates to a vehicle water immersion test device. Background Technology

[0002] In the manufacturing of motorcycles or electric vehicles, immersion tests such as car wash tests, rain tests, and wading tests are required before the vehicle leaves the factory to test its sealing performance. In the prior art, for example, Chinese utility model patent CN211602430U, entitled "An Automobile Rain Testing Device," discloses an automobile rain testing device, including a spray system, an electrical control system, and a chassis. The spray system is arranged around the perimeter of the chassis, and the electrical control system is connected to the spray system. Lifting mechanisms capable of fixing automobile tires are provided at the four corners of a rectangular area of ​​the chassis, and the electrical control system is connected to and independently controls each lifting mechanism.

[0003] However, the above technical solution has the following technical defects: 1. Because the openings on both sides of the chassis are open, it cannot store water. Therefore, during use, only car wash tests and rain tests can be performed on the vehicle, but water wading tests cannot be performed on the same equipment, which reduces the testing efficiency; 2. During the test, the vehicle is static and does not have a multi-directional dynamic measurement state, resulting in insufficient testing capabilities. It is possible that there is no water leakage in the static test, but water leakage occurs in actual market use. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle water wading test device to solve the technical problems of existing car rain test equipment that can only perform car wash tests and rain tests on vehicles during use, but cannot perform water wading tests on the same equipment, and cannot perform dynamic tests on vehicles.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vehicle water spray test device, characterized in that: it includes a test chamber, the test chamber has a spray space for accommodating the vehicle to be tested, and an entrance for the vehicle to enter and exit is provided on one side of the test chamber. A shift door is movably disposed at the entrance of the test chamber to open or close the spray space. When the shift door is closed, the spray space forms a water storage chamber. A spray unit is installed inside the test chamber and arranged around the spray space.

[0006] Preferably, the bottom of the test chamber is provided with a rotating lifting device, which is used to lift and rotate the vehicle.

[0007] Preferably, the rotating lifting device includes a lifting mechanism and a rotating mechanism. The lifting mechanism and the rotating mechanism are installed below the test chamber. The driving end of the lifting mechanism extends into the spray space and the lifting mechanism is fixed on the rotating mechanism. A base is fixedly connected to the driving end of the lifting mechanism.

[0008] Preferably, the test chamber includes a base, and the upper surface of the base is provided with a left side plate, a right side plate and a rear side plate respectively. The shift door is movably disposed on the side of the left side plate and the right side plate away from the rear side plate. The base, the left side plate, the right side plate, the rear side plate and the shift door surround each other to form a water storage cavity.

[0009] Preferably, the entrance is provided with a guide rail, and the sliding door moves on the guide rail. When the sliding door is closed, the two sides of the sliding door are sealed to the left side plate and the right side plate, respectively.

[0010] Preferably, a water tank is provided below the base, and a drain outlet connected to the water tank is provided on the base. An electrically controlled valve is provided at the drain outlet, and the opening and closing of the electrically controlled valve is used to control drainage or water storage.

[0011] Preferably, it also includes a water circulation system, which includes a water tank, a drain pipe, an outlet pipe, and a water pump. The water tank is connected to the water tank through the drain pipe, and the spray unit is connected to the water pump through the outlet pipe and connected to the water tank through the water pump.

[0012] Preferably, the spraying unit is a spray head, which is movably mounted on the test chamber at multiple angles to spray the vehicle under test from multiple angles.

[0013] Preferably, the test chamber is equipped with a water level gauge plate for measuring water level.

[0014] Preferably, the test chamber is made of high-strength transparent glass.

[0015] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: 1. By setting up a test chamber with an internal spray space, and opening an entrance for vehicles to enter and exit the spray space on one side of the test chamber, when the vehicle under test enters the spray space from the entrance, the shift door is closed, so that the shift door and the test chamber are enclosed and the joint between the two is relatively sealed. At this time, the enclosed inner side will form a water storage chamber. Then the spray unit starts to spray the vehicle, completing the car wash test and rain test of the vehicle. During this process, the spray unit sprays water... Water accumulates in the water storage chamber, and the water level rises continuously after continuous spraying. The rising water level completes the immersion test of the vehicle. After the test, the water is discharged by controlling the electronically controlled valve at the bottom of the test chamber. In this way, car wash tests, rain tests, and immersion tests can all be performed in the same equipment, shortening the entire testing process, improving testing efficiency, and solving the technical problem that existing car rain test equipment can only perform car wash tests and rain tests on vehicles and cannot perform immersion tests on the same equipment.

[0016] By installing a rotating lifting device at the bottom of the test chamber, the vehicle can be raised and lowered through the lifting mechanism in the rotating lifting device, so that the wheels leave the ground. In addition, the vehicle can be rotated through the rotating mechanism fixedly connected to the drive end of the lifting mechanism, so that the vehicle can be dynamic during the test. This allows the vehicle to fully simulate the outdoor rain environment, thereby improving the test capability and solving the technical problem that existing automobile rain test equipment cannot perform dynamic testing of vehicles.

[0017] The spray unit of this invention can be installed in the test chamber at multiple angles, allowing the spray unit to cover a larger and more comprehensive area.

[0018] This utility model's water circulation system first opens an electrically controlled valve, allowing wastewater from the storage chamber to flow into a water tank below the test chamber base. Then, water from the tank and the storage chamber is drained from the test chamber through a drain pipe. A filter along the drain pipe removes impurities from the wastewater before it is stored in the water tank. When testing is required again, a water pump powers the system, and a flow meter along the outlet pipe limits the flow rate. Finally, a spray test is conducted using a spray head. Once the water depth in the storage tank reaches a certain level, a wading test can be performed. This continuous circulation of test water significantly improves water resource utilization.

[0019] By installing a water level gauge inside the test chamber, with a measurement range of 100mm-1300mm, and in conjunction with a rotating lifting device, dynamic water wading measurements of vehicles can be achieved.

[0020] By setting up a test chamber made of fully transparent high-strength glass, it is not only waterproof but also allows for effective observation of the condition of the test vehicle and the environment inside the chamber. The high strength also allows it to withstand large impacts, ensuring test safety. Attached Figure Description

[0026] like Figure 1-5 As shown: A vehicle water spray testing device includes a test chamber 1, a shift door 2, and a spray unit 4. The test chamber 1 is a spray chamber with a top opening and an entrance. The test chamber 1 has a spray space for accommodating the vehicle to be tested. An entrance for the vehicle to enter and exit is opened on one side of the test chamber 1. The shift door 2 is movably installed at the entrance of the test chamber 1 to open or close the spray space. When the shift door 2 is closed, the spray space forms a water storage chamber 3. The spray unit 4 is installed inside the test chamber 1 and arranged around the spray space. A test chamber 1 with an internal spray space is set up, and an entrance for vehicles to enter and exit the spray space is opened on one side of the test chamber 1. When the vehicle under test enters the spray space through the entrance, the shift door 2 is closed, so that the shift door 2 and the test chamber 1 are enclosed and their joint is relatively sealed. At this time, the enclosed inner side forms a water storage chamber 3. Then the spray unit 4 starts spraying the vehicle to complete the car wash test and rain test. During this process, the water sprayed by the spray unit 4 will accumulate in the water storage chamber 3. After the water is sprayed, the water level in the water storage chamber 3 will rise continuously. The rising water level completes the immersion test of the vehicle. After the test is completed, the water can be discharged by controlling the electronically controlled valve at the bottom of the test chamber 1. In this way, car wash test and rain test can be carried out in the same equipment, as well as immersion test. This shortens the entire test process, improves test efficiency, and solves the technical problem that the existing car rain test equipment can only carry out car wash test and rain test and cannot carry out immersion test in the same equipment.

[0027] like Figure 1As shown: The bottom of the test chamber 1 is equipped with a rotating lifting device 5. The rotating lifting device 5 is used to lift and rotate the vehicle. By setting the rotating lifting device 5 at the bottom of the test chamber 1, the vehicle can be lifted and lowered by the lifting mechanism in the rotating lifting device 5, so that the wheels leave the ground. In addition, the vehicle can be rotated by the rotating mechanism, so that the vehicle can be dynamic during the test. This allows the vehicle to fully simulate the outdoor rain environment, thereby improving the test capability and solving the technical problem that existing car rain test equipment cannot perform dynamic testing of vehicles.

[0028] like Figure 3-4 As shown: The rotating lifting device includes a lifting mechanism and a rotating mechanism. The lifting mechanism is installed below the test chamber 1. The drive end of the lifting mechanism extends into the spray space and is fixed on the rotating mechanism. A platform 501 is fixedly connected to the drive end of the lifting mechanism. The platform 501 and the lifting mechanism move synchronously. An operating cavity is provided below the test chamber 1. The rotating mechanism is installed in the operating cavity. The rotating end of the rotating mechanism is equipped with a lifting mechanism. The drive end of the lifting mechanism extends into the spray space through a slot opened at the bottom of the test chamber 1. The slot and the outer surface of the drive end are aligned and sealed between them to prevent water from flowing into the operating cavity. When the vehicle needs to be lifted for testing, the lifting mechanism is started first. The push end of the lifting mechanism drives the platform to move upward to lift the vehicle. Then the rotating mechanism is started to drive the lifting mechanism fixed on its rotating end to rotate, thereby synchronously driving the vehicle to rotate. In this embodiment, the lifting mechanism and the rotating mechanism are existing technologies and will not be described in detail here.

[0029] like Figure 1-4 As shown: The test chamber 1 includes a base 101. The upper surface of the base 101 is provided with a left side plate 102, a right side plate 103 and a rear side plate 104 respectively. The shift door 2 is movably disposed on the side of the left side plate 102 and the right side plate 103 away from the rear side plate 104. The base 101, the left side plate 102, the right side plate 103, the rear side plate 104 and the shift door 2 enclose each other to form a water storage chamber 3. An operating chamber is provided below the base 101. The base 101 has a slot that communicates with the operating chamber to allow the drive end to enter the spray space. The left side plate 102, the right side plate 103 and the rear side plate 104 are integrally formed on the upper surface of the base 101 to increase the overall strength and sealing of the test chamber 1.

[0030] like Figure 1-2As shown: A guide rail is provided at the entrance, and the sliding door 2 moves on the guide rail. The guide rail facilitates the movement of the sliding door 2. The guide rail can be set at the upper and lower ends of the entrance, and a sealing strip can be installed in the guide rail to improve the sealing performance. When the sliding door 2 is closed, both sides of the sliding door 2 are sealed to the left side plate 102 and the right side plate 103, respectively. In this embodiment, the sliding door 2 is an electric sliding door, which is electrically controlled to facilitate vehicle entry and exit. At the same time, when the sliding door 2 is closed, its two sides are tightly sealed to the test chamber 1 through waterproof seals to prevent water leakage.

[0031] like Figure 4-5 As shown: A water tank 6 is provided below the base 101, and a drain outlet connected to the water tank 6 is provided on the base 101. An electric control valve is provided at the drain outlet. The opening and closing of the electric control valve can control the drainage or water storage. Drainage can be achieved by setting an electric control valve. It should be noted that the electric control valve can also be installed at the connection between the water tank 6 and the drain pipe 9. A filter screen 12 connected to the water tank 6 is provided on the base 101.

[0032] like Figure 5 As shown: It also includes a water circulation system, which includes a water tank 8, a drain pipe 9, a water outlet pipe 10 and a water pump 11. The water tank 6 is connected to the water tank 8 through the drain pipe 9. The spray unit 4 is connected to the water pump 10 through the water outlet pipe 10 and connected to the water tank 8 through the water pump 11.

[0033] This utility model's water circulation system first opens an electrically controlled valve, allowing wastewater from the storage chamber to flow into a water tank below the test chamber base. Water from the tank then drains from the tank and storage chamber 3 through a drain pipe 9, emptying the test chamber 1. A filter along the drain pipe 9 removes impurities from the wastewater before it is stored in a water tank 8. When testing is required again, a water pump 11 powers the system, with a flow meter on the outlet pipe 10 controlling the flow rate. Finally, a spray test is conducted using a spray head. Once the water depth in the storage tank reaches a certain level, a wading test can be performed. This continuous circulation of test water significantly improves water resource utilization. The system also includes an electrical control system that controls the spray unit 4 and the rotating lifting device 5, as well as the electrically controlled valve and water pump 11 to achieve water output, drainage, storage, and self-circulation.

[0034] like Figure 1-4As shown: Spray unit 4 is a spray head. The spray head is movably mounted on the test chamber 1 at multiple angles and is used to spray the vehicle under test from multiple angles. In this embodiment, there are multiple spray units 4, all of which are connected to the internal flow pipes set on the test chamber 1. The internal flow pipes are respectively arranged in the middle position of the left side plate 102, the right side plate 103 and the rear side plate 104. Each internal flow pipe is connected to the other. The internal flow pipe is connected to the water pump 11 through the water outlet pipe 10. When the water pump 11 is started, the water pump draws water from the water tank 8 and flows through the water outlet pipe 10 into each internal flow pipe, and disperses it into the spray head on the internal flow pipe, and then sprays it out from the spray head.

[0035] The spray head includes a nozzle and a metal hose, which are detachably connected. The metal hose can be rotated at multiple angles, allowing the spray unit 4 to cover a larger and more comprehensive area.

[0036] like Figure 1-3 As shown: The test chamber 1 is equipped with a water level plate 7 for measuring water level. By setting the water level plate 7 inside the test chamber, the measurement range of the water level plate 7 is 100mm-1300mm. With the help of the rotating lifting device, dynamic water wading measurement of vehicles can be realized.

[0037] Test chamber 1 is made of high-strength transparent glass. By setting up test chamber 1 made of fully transparent high-strength glass, it is not only waterproof but also allows for effective observation of the condition of the test vehicle and the environment inside the equipment. It is also of high strength and can withstand large impacts to ensure test safety. In addition, the sliding door 2 can also be designed to be made of glass for easier observation.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
