Description

Technical Field

[0001] This utility model belongs to the field of spoiler testing technology, and more specifically, it relates to a spoiler test bench. Background Technology

[0002] A spoiler is a hydrodynamic device mounted on the back or wing of vehicles such as cars, airplanes, and racing cars. It alters the flow of air to reduce speed, improve handling stability, and enhance braking force. Spoilers utilize the principle that fluid velocity decreases pressure. A car's rear wing can be viewed as an inverted wing, and a spoiler on the chassis accelerates the airflow passing under the chassis, resulting in lower pressure under the car and higher pressure above, keeping the car firmly planted on the ground and thus improving stability at high speeds.

[0003] Based on the above, the following problems were found: Before the spoiler is installed on the vehicle, its aerodynamic function needs to be tested. However, the existing tests usually involve fixing the spoiler and testing its rigidity, but do not test its aerodynamic function in detail. As a result, the aerodynamic effect of the spoiler cannot be well understood during normal use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spoiler test bench to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a spoiler test bench, which solves the problem that current tests typically involve directly fixing the spoiler and testing its stiffness, but do not conduct detailed tests on its spoiling function.

[0006] This utility model provides a spoiler test bench, which is achieved by the following specific technical means:

[0007] A spoiler test bench includes a test bench body. Baffles are fixed on both sides of the top of the test bench body. A fan is fixed to the bottom of one end of the test bench body. An air guide tube is provided on the outer wall of the fan. Two ends of one side of the air guide tube are respectively fixed to one end of the two baffles. A first support rod is fixed to the end of the baffle away from the air guide tube. A wind speed sensor is fixed to the top of the first support rod. A movable shaft is movably sleeved through the two baffles near the end of the first support rod. A limit mechanism is fixed on the opposite side of the two movable shafts. A guide rail is fixed in the middle of one side of the bottom of the test bench body. A clamping mechanism is provided inside the guide rail.

[0008] Furthermore, a rotary switch is fixed to one side of one of the baffles, and the rotary switch is electrically connected to the fan.

[0009] Furthermore, multiple wind speed sensors are provided, and the multiple wind speed sensors are arranged horizontally at equal intervals, and the horizontal height of the wind speed sensors is greater than the horizontal height of the moving shaft.

[0010] Furthermore, the clamping mechanism includes a servo motor, the power output end of which is fixed with a first threaded rod. The first threaded rod has two threaded rods threaded through it on both sides of its middle section. The two moving rods have opposite thread directions and are rotatably connected to the two moving shafts respectively. Both moving rods are slidably connected to the guide rail.

[0011] Furthermore, a second support rod is fixed to the middle of one side of one of the movable rods, and an electric telescopic rod is fixed to one end of the second support rod. An active rack is fixed to the power output end of the electric telescopic rod.

[0012] Furthermore, a driven gear is fixed to the outer wall of one of the moving shafts, the driven gear meshing with the driving rack, and a scale groove is horizontally and equidistantly opened on the top of the second support rod.

[0013] Furthermore, the limiting mechanism includes a limiting block, which is fixed to the moving shaft. The limiting block is U-shaped, and a second threaded rod is threadedly connected to the top of the limiting block. A first knob is fixed to the top of the second threaded rod, and a pressing block is rotatably connected to the bottom of the second threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the two ends of the spoiler are placed in the middle of two extrusion blocks, and then the rotation speed of the fan is controlled by rotating the knob switch after limiting the position. This controls the wind force in the air duct, simulating the wind force at different speeds when a car is driving. The wind speed is detected behind the spoiler by a wind speed sensor. The turbulence effect of different positions of the spoiler is judged based on the values ​​of multiple wind speed sensors and the wind force in the air duct. This allows for detailed testing and detection of the spoiler's turbulence function.

[0016] 2. In this utility model, the position of the limiting block is adjusted according to the length of the spoiler. The position of the two moving rods is adjusted by the rotation of the first threaded rod driven by the servo motor, and the position of the squeezing block is adjusted so that the squeezing block fixes the spoiler in the limiting block, thereby achieving the effect of being suitable for spoilers of various sizes. By controlling the extension and retraction of the electric telescopic rod, the position of the active rack is adjusted, which drives the driven gear to rotate, and then drives the limiting mechanism to rotate, so that the angle of the spoiler can be changed and the effect of multi-angle testing can be achieved.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a spoiler test bench, including a test bench body 1. Baffles 5 are fixed on both sides of the top of the test bench body 1. A fan 2 is fixed at the bottom of one end of the test bench body 1. A guide tube 3 is provided on the outer wall of the fan 2. Two ends of one side of the guide tube 3 are fixed to one end of the two baffles 5 respectively. A first support rod 6 is fixed at the end of the baffle 5 away from the guide tube 3. A wind speed sensor 7 is fixed at the top of the first support rod 6. A movable shaft 11 is movably sleeved through the ends of the two baffles 5 near the first support rod 6. A limit mechanism is fixed on the opposite side of the two movable shafts 11. A guide rail 8 is fixed in the middle of one side of the bottom of the test bench body 1. A clamping mechanism is provided inside the guide rail 8.

[0028] One of the baffles 5 has a rotary switch 4 fixed on one side. The rotary switch 4 is electrically connected to the fan 2. By rotating the rotary switch 4, the rotation speed of the fan 2 is controlled, thereby controlling the wind force in the air duct 3, simulating the wind force at different speeds when a car is driving.

[0029] The wind speed sensor 7 is provided in multiple ways. The multiple wind speed sensors 7 are arranged horizontally at equal intervals, and the horizontal height of the wind speed sensor 7 is greater than the horizontal height of the moving shaft 11. The wind speed is detected behind the spoiler by the wind speed sensor 7. The turbulence effect at different positions of the spoiler is judged based on the values ​​of multiple wind speed sensors 7 and the wind force of the air duct 3.

[0030] The clamping mechanism includes a servo motor 9, the power output end of which is fixed with a first threaded rod 91. The two sides of the middle of the first threaded rod 91 are threadedly connected to moving rods 10. The threads of the two moving rods 10 are opposite, and the two moving rods 10 are rotatably connected to two moving shafts 11 respectively. Both moving rods 10 are slidably connected to the guide rail 8. During the test, the position of the two moving rods 10 is adjusted by rotating the first threaded rod 91 driven by the servo motor 9 to adapt to the length of the spoiler.

[0031] One of the movable rods 10 has a second support rod 16 fixed to the middle of one side. An electric telescopic rod 18 is fixed to one end of the second support rod 16. An active rack 19 is fixed to the power output end of the electric telescopic rod 18. During the test, the position of the active rack 19 can be adjusted by controlling the extension and retraction of the electric telescopic rod 18. A driven gear 20 is fixed to the outer wall of one of the movable shafts 11. The driven gear 20 meshes with the active rack 19. The top of the second support rod 16 has horizontally equidistant graduated grooves 17. When the active rack 19 moves, it drives the driven gear 20 to rotate, which in turn drives the limiting mechanism to rotate, thereby changing the angle of the spoiler. This can simulate the uphill and downhill driving of a car.

[0032] The limiting mechanism includes a limiting block 12, which is fixed to the moving shaft 11. The limiting block 12 is U-shaped, and a second threaded rod 13 is threadedly connected to the top of the limiting block 12. A first knob 15 is fixed to the top of the second threaded rod 13, and a pressing block 14 is rotatably connected to the bottom of the second threaded rod 13. After the position of the moving rod 10 is adjusted, the two ends of the spoiler are placed in the middle of the two pressing blocks 14. Then, by rotating the first knob 15, the second threaded rod 13 is rotated to adjust the position of the pressing block 14, so that the pressing block 14 fixes the spoiler in the limiting block 12.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, firstly, the position of the limiting block 12 is adjusted according to the length of the spoiler. Then, the servo motor 9 drives the first threaded rod 91 to rotate, thereby adjusting the position of the two moving rods 10. This positions the two limiting blocks 12 at both ends of the spoiler, placing the two ends of the spoiler in the middle of the two extrusion blocks 14. Next, rotating the first knob 15 drives the second threaded rod 13 to rotate, adjusting the position of the extrusion blocks 14 so that they fix the spoiler in the limiting blocks 12. Finally, rotating the knob switch 4 controls the rotation speed of the fan 2, thereby controlling the airflow in the air duct 3. The system simulates the wind force at different speeds when the vehicle is driving. Wind speed is detected behind the spoiler by wind speed sensor 7. The turbulence effect of different positions of the spoiler is judged based on the values ​​of multiple wind speed sensors 7 and the wind force of the air duct 3. During the test, the position of the active rack 19 can be adjusted by controlling the extension and retraction of the electric telescopic rod 18. The tilt angle of the spoiler is judged by the scale groove 17. When the active rack 19 moves, it drives the driven gear 20 to rotate, which in turn drives the limiting mechanism to rotate, so that the angle of the spoiler changes. This can simulate the uphill and downhill driving of the vehicle.
