Description

Technical Field

[0001] The utility model relates to a vehicle testing tool, in particular to a vehicle cooling system test bench. Background Art

[0002] The current vehicle cooling system test is limited by the space of the vehicle. When the cooling system components fail, it is difficult to troubleshoot and replace the components. The operation is inconvenient and the workload is large. If the vehicle is tested on the road, it will also be affected by external factors such as the test road and test weather. The test cycle is long and the test data is unstable.

[0003] The vehicle cooling system test bench simulates the actual vehicle cooling system to test the functions of each component of the system. The test content includes the test of the functions and working parameters of the motor and electronic control system, battery system, heating system and the radiator assembly in the heating assembly, water circuit integrated module assembly, PTC assembly, water pump, water valve, etc. During the test process, the flow, pressure, temperature and other parameters of each system and component can be collected, and the collected data can be recorded, saved and output into documents in real time.

[0004] At the same time, since the vehicle cooling system has many components, each component needs to be filled with cooling liquid during the test. For test needs, the cooling system components are frequently replaced during the test. Leakage often occurs during the disassembly of the pipeline. Some liquid will remain inside the disassembled components. The coolant often flows to the remaining components or the ground in the test area, which not only wastes coolant, but also poses potential safety risks and pollutes the environment. When workers collect and recycle the leaked liquid, there are high safety risks, high labor intensity, and a long time.

[0005] Therefore, the vehicle cooling system is tested on a cooling system bench, which makes it easy to replace parts and adjust test parameters for various tests. Utility Model Content

[0017] In order to more clearly and completely express the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1As shown, the utility model provides a vehicle cooling system test bench, which simulates a whole vehicle frame of a real vehicle, and has a size close to or even the same as that of the real vehicle frame.

[0019] The test stand is configured by a main frame 1, which is constructed of industrial aluminum profiles, is light in weight, and is easy to adjust; a stainless steel perforated plate 2 is arranged on the side of the main frame 1 to protect the components inside the frame and also facilitate heat dissipation, and the stainless steel perforated plate 2 can also fix the components of the cooling system. A supportable universal wheel 3 is installed at the bottom of the test stand, so that the test stand can be moved or fixed.

[0020] The test bench is composed of three parts: the front, the middle and the rear. The three parts can be assembled into a whole, or they can be moved independently. The positions of the three parts can be adjusted according to the test needs. The front, rear and middle parts of the test bench are connected by a movable small door 4. When installing the cooling system components, the movable small door 4 can be opened to enter the test bench to operate the cooling system components, which is convenient for manual operation. The movable small door 4 is made of a perforated plate 2 surrounded by the side, but the perforated plate is movable. One end of the perforated plate is installed on the main frame through a hinge, and the other end is connected to the frame with a lock. The movable small door 4 can be flipped 180°. When it is opened 180°, the distance between the front, rear and middle parts of the test bench can be reduced, which is equivalent to reducing the length of a small door, so the overall footprint of the test bench is reduced, which can save space.

[0021] The front and rear of the test bench are equipped with adjustable mounting brackets 5 for fixing the components of the cooling system. The components of the cooling system are mounted on the test bench to simulate the positions of the components in the actual vehicle, and the components of the cooling system are connected to the pipe circulation system in the middle of the test bench through hoses.

[0022] A pipeline circulation system 6 is installed in the middle of the rack. Figure 2 As shown, the pressure, temperature and flow of the cooling system can be controlled, and the parameters can be adjusted in real time according to the test requirements through the electronic control system.

[0023] A multi-channel pipeline circulation system 6 can be installed in the middle of the test bench. Each pipeline circulation system is equipped with water storage tanks 61 of different specifications and stainless steel pipes 62 of different diameters to meet the requirements of the cooling system components for pipeline flow and pressure. Each pipeline circulation system is installed with electrical components such as pressure sensor 63, temperature sensor 64, flow sensor 65, water resistance simulator 66, differential pressure sensor 67, etc. The pressure, temperature and flow of the cooling system are monitored and controlled through the electronic control system 7. The test parameters can be modified on the electronic control system to conduct various tests, and the test data can be generated into documents, saved and output.

[0024] In addition, a liquid receiving tray 8 is installed at the bottom of the stand. Especially at the pipeline part, when disassembling parts, the residual liquid in the pipeline can drip onto the liquid receiving tray, which is convenient for workers to collect and recycle.

[0025] This test bench can be used to simulate the cooling system of the entire vehicle, and is convenient for adjusting the size of the test bench, setting up the pipelines, and adjusting the test parameters. It can be used to simulate different vehicle model tests, and has strong applicability.
