Description

Technical Field

[0001] This application relates to the technical field of vehicle testing, and in particular to a comprehensive testing system for flying cars. Background Technology

[0002] Flying cars, as a new concept of transportation integrating land driving and air flight capabilities, represent an important development direction in the future of three-dimensional transportation. Unlike conventional land vehicles, flying cars must withstand significantly greater wind noise during flight than when driving on land. Furthermore, their operation is highly susceptible to the effects of natural climatic environments such as rain, snowfall, extreme temperatures, and salt spray. The vehicle's aerodynamic performance, wind noise characteristics, and environmental reliability directly determine its safety and ride comfort. Therefore, before finalizing a flying car product design, a comprehensive and systematic performance evaluation must be conducted. The obtained test data is the core basis for optimizing vehicle structural parameters and improving overall vehicle performance.

[0003] Currently, the industry generally adopts a separate testing approach for the performance testing of flying cars: wind noise testing and climate environment reliability testing must be completed separately in two independent sets of equipment. In related technologies, the flying car or model under test needs to be repeatedly disassembled, assembled, and transported between different devices, resulting in a cumbersome testing process and low testing efficiency. Summary of the Invention

[0004] To improve testing efficiency, this application provides a comprehensive testing system for flying cars.

[0005] This application provides a comprehensive testing system for flying cars, which adopts the following technical solution: A comprehensive testing system for flying cars includes a wind noise testing wind tunnel, an acoustic cabin, an environmental wind tunnel, a sealed door, a track, a platform, and an environmental simulation device; The acoustic chamber is located inside the wind noise test tunnel, and the sealing door is located between the wind noise test tunnel and the environmental wind tunnel. Opening and closing the sealing door controls the connection between the wind noise test tunnel and the environmental wind tunnel.

The deployment drive source drives the movable support rod to move, so that the movable support rod adjusts the spacing of the plurality of environmental simulation units through the second scissor mechanism.

[0016] By adopting the above technical solution, and through the coordinated cooperation of the unfolding component and the spacing adjustment component, the spacing adjustment of the environmental simulation unit in two mutually perpendicular directions in the plane is realized.

The water supply pipe is connected to the mounting base, and the nozzle is connected to the water supply pipe.

[0020] By adopting the above technical solution, the delivery pipe transports snow particles and sprays them out of the nozzle, while the water delivery pipe transports water flow and sprays it out of the nozzle. The structure is simple and reliable, and it can control the amount of snowfall and rainfall, simulate precipitation and snowfall environments of different intensities, and provide accurate climate conditions for the environmental reliability testing of flying cars.

[0032] refer to Figure 3 and Figure 4 The inner bottom walls of the wind noise test wind tunnel 1 and the environmental wind tunnel 3 are provided with grooves. The track 5 is laid in the grooves of the wind noise test wind tunnel 1 and the environmental wind tunnel 3. The two ends of the track 5 extend to the center of the test position of the wind noise test wind tunnel 1 and the environmental wind tunnel 3, respectively. The bottom side of the sealing door 4 is fixedly connected with a sealing strip.

[0033] refer to Figure 3 and Figure 4 The support platform 6 is mounted on the track 5, and rollers that cooperate with the track 5 are installed at the bottom of the support platform 6, allowing the support platform 6 to move along the track 5. The acoustic cabin 2 includes a cabin body 21 and a cabin door 22. The cabin door 22 is installed on the side wall of the cabin body 21 and is an electrically operated sliding door. By stopping the airflow in the wind noise test wind tunnel 1 and the environmental wind tunnel 3, and then opening the cabin door 22 and the sealing door 4, the support platform 6 can move smoothly between the wind noise test wind tunnel 1 and the environmental wind tunnel 3 along the track 5. A fixture for fixing the flying car or flying car model is fixedly connected to the upper surface of the support platform 6 to ensure the positional stability of the vehicle under test during the test.

Multiple acoustic sensors are installed inside and outside the flying car. Then, the cabin door 22 and the sealing door 4 are closed, and airflow is generated in the wind tunnel 1 to conduct wind noise testing on the flying car. After the wind noise test is completed, the sealing door 4 is opened, and the support platform 6 is driven to move along the track 5, thereby moving the flying car into the environmental wind tunnel 3 for subsequent climate environment simulation testing.

The lifting assembly 712 is used to drive the mounting base 72 to move vertically. Through the cooperation of the moving drive component 711 and the lifting assembly 712, the position adjustment of the mounting base 72 in the horizontal and vertical directions is realized, enabling the environmental simulation unit 75 to adjust its position according to the specific position and height of the tested flying car.

[0037] refer to Figure 3 and Figure 5 The rotating assembly 713 employs a motor-driven rotary table. The body of the rotating assembly 713 is fixedly connected to the output end of the moving drive component 711. The output end of the rotating assembly 713 drives the lifting assembly 712 to rotate, thereby driving the mounting base 72 to rotate, allowing the fixed support rod 73 to switch between a horizontal and a vertical state. During static testing, no airflow is generated in the environmental wind tunnel 3, and the rotating assembly 713 keeps the fixed support rod 73 in a horizontal state. The environmental simulation unit 75 applies climate environment simulation to the tested flying car from top to bottom. During dynamic testing, airflow is generated in the environmental wind tunnel 3, and the rotating assembly 713 rotates the fixed support rod 73 to a vertical state.

Through the coordinated cooperation of the spacing adjustment component 76 and the deployment component 77, the spacing of the environmental simulation units 75 in two mutually perpendicular directions in the plane (i.e., the arrangement direction of the multiple support connecting rods 74 and the length direction of the support connecting rods 74) can be adjusted, enabling the environmental simulation units 75 to adjust their density and position in a two-dimensional plane according to the specific outline of the flying car under test, ensuring the uniformity and comprehensiveness of the environmental simulation.

[0041] refer to Figure 6 and Figure 7 The environmental simulation unit 75 includes a mounting base 751 and a snowfall simulation module 752, a rainfall simulation module 753, a salt spray simulation module 754, and a temperature simulation module 755 connected to the mounting base 751.

The delivery pipe 7521 is fixedly connected to the mounting base 751, and the nozzle 7522 communicates with the delivery pipe 7521. The delivery pipe 7521 is externally connected to a snowmaking machine. The delivery pipe 7521 delivers snow particles and sprays them out from the nozzle 7522. The snow particles fall onto the surface of the flying car to simulate a snowfall environment.

[0042] refer to Figure 6 and Figure 7 The rainfall simulation module 753 includes a water supply pipe 7531 and a nozzle 7532. The water supply pipe 7531 is fixedly connected to the mounting base 751, and the nozzle 7532 is connected to the water supply pipe 7531. The water supply pipe 7531 is connected to an external water pump. The water supply pipe 7531 delivers water flow and sprays it out from the nozzle 7532 in the form of raindrops to simulate rainfall environments of different intensities.

[0043] refer to Figure 6 and Figure 7 The salt spray simulation module 754 includes a brine delivery pipe 7541 and a salt spray nozzle 7542. The brine delivery pipe 7541 is fixedly connected to the mounting base 751, and the salt spray nozzle 7542 is connected to the brine delivery pipe 7541.

The hot air duct 7551 is connected to an external hot air fan and is used to blow out hot air. The cold air duct 7552 is connected to a cold air fan and is used to blow out cold air. By controlling the start / stop and flow rate of the hot air duct 7551 and the cold air duct 7552 respectively, tests at different temperatures can be conducted to evaluate the performance of the flying car under different temperature conditions.

[0045] refer to Figure 5 and Figure 7During static testing, no airflow is generated in the environmental wind tunnel 3. The rotating component 713 drives the lifting component 712 to rotate, keeping the fixed support rod 73 in a horizontal position. At this time, the delivery pipe 7521 delivers snow particles and sprays them out from the nozzle 7522. The sprayed snow particles fall onto the flying car under the action of gravity, thus simulating snowfall. Subsequently, the water delivery pipe 7531 delivers water and sprays it out from the nozzle 7532, simulating rainfall. Then, the salt water delivery pipe 7541 of the salt spray simulation module 754 delivers salt water and sprays it out from the salt spray nozzle 7542 to simulate salt spray. Subsequently, the temperature simulation module 755 blows hot air onto the flying car through the hot air pipe 7551 and then blows cold air onto the flying car through the cold air pipe 7552 to simulate temperature. By applying the above-mentioned multiple climatic factors in sequence or combination, the reliability of the flying car in different environments can be evaluated.

[0046] refer to Figure 5 and Figure 7 During dynamic testing, the rotating component 713 causes the lifting component 712 to rotate, making the fixed support rod 73 vertical. At this time, airflow is generated in the environmental wind tunnel 3. Under the action of the airflow, snow particles, raindrops, salt spray or temperature-regulating airflow sprayed by the environmental simulation unit 75 can act on the surface of the flying car to evaluate the environmental adaptability of the flying car in driving mode.

[0047] refer to Figure 5 and Figure 6 When simulating the climate environment for flying cars of different models, the position and spacing of the environmental simulation units 75 can be adjusted using the spacing adjustment component 76 and the deployment component 77. Specifically, the adjustment drive source 762 moves the first support slider 761 via the first scissor mechanism 763, and the first support slider 761 moves the load-bearing connecting rod 74, thereby adjusting the spacing between the multiple load-bearing connecting rods 74. The deployment drive source 773 moves the moving load-bearing rod 771, and the moving load-bearing rod 771 moves the multiple environmental simulation units 75 via the second scissor mechanism 774, thereby adjusting the spacing of the environmental simulation units 75 on the same load-bearing connecting rod 74. Through the joint adjustment of the spacing adjustment component 76 and the deployment component 77, the distribution of multiple environmental simulation units 75 in the plane can be adjusted to meet the testing requirements of flying cars of different sizes.

[0048] The implementation principle of the integrated testing system for flying cars in this application embodiment is as follows: By integrating wind noise testing and environmental simulation testing functions into the same system, the flying car under test can be transferred between different testing areas, avoiding the cumbersome process of repeatedly disassembling and transferring the vehicle under test in traditional testing schemes, thus improving testing efficiency. Simultaneously, the rotation component 713 enables the attitude transformation of the environmental simulation unit 75 between static and dynamic testing; the spacing adjustment component 76 and the deployment component 77 enable the spacing adjustment of the environmental simulation unit 75 in a two-dimensional plane; and the modularly designed environmental simulation unit 75 simulates various climatic factors, enabling a comprehensive evaluation of the flying car's environmental adaptability and reliability.
