Description

Technical Field

[0001] The present invention relates to the field of automobile detection, and more specifically, to an auxiliary device for detecting new energy automobile parts. Background Art

[0002] Auto parts are the various units that make up the whole car and are a kind of product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is also increasing. Automobile inspection is to determine the technical condition or working ability of the car, especially the inspection of the fuel tank.

[0003] The air tightness test of automobile fuel tanks is mainly based on the principle of air pressure simulating water pressure. By applying a certain pressure to the inside of the fuel tank and observing the performance of the fuel tank under water immersion, it can be judged whether its sealing performance meets the standard. First, you need to ensure that the surface of the fuel tank is clean and free of impurities. Then, fix the fuel tank to prevent it from moving or tilting during the inspection. Immerse the fuel tank completely in water and ensure that the water level is high enough to completely cover all possible leakage points of the fuel tank. Inflate the fuel tank or increase the external water pressure to form a certain pressure difference inside the fuel tank. This pressure difference should be large enough to produce obvious bubbles when there is a leak in the fuel tank. Carefully observe the water surface around the fuel tank to find out whether there are bubbles. If there are bubbles, it means that the fuel tank is leaking. If there are no bubbles, it means that the sealing performance of the fuel tank is good. However, bubbles may be trapped in some gaps or complex structures on the outer surface of the fuel tank. These bubbles may suddenly pop out during the detection process, resulting in misjudgment as leakage points, thereby reducing the accuracy of the detection. For this reason, we propose an auxiliary device for detecting new energy vehicle accessories. Summary of the invention

DETAILED DESCRIPTION

[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0019] like Figure 1 - Figure 8 As shown, an auxiliary device for testing new energy automobile parts includes: a workbench 11, a water tank 12 filled with clean water is arranged in the workbench 11, and a car fuel tank 13 to be tested is placed in the water tank 12, an auxiliary arm 14 is arranged above the water tank 12, and a pressing mechanism 2 for pressing the car fuel tank 13 into the clean water in the water tank 12 is arranged at one end of the auxiliary arm 14 close to the water tank 12; The pressing mechanism 2 includes a tank pressing member and an air bubble exhaust mechanism 3. The air bubble exhaust mechanism 3 is arranged below the tank pressing member and inserted into the oil filling port of the automobile oil tank 13. The automobile oil tank 13 is pressed down by the tank pressing member so that the automobile oil tank 13 is immersed in the clean water of the water reservoir 12. The bubble removal mechanism 3 includes a box shaking bubble removal component and an impact bubble removal component. The impact bubble removal component is arranged around the box shaking bubble removal component and impacts in different directions in the automobile fuel tank 13. The box shaking bubble removal component makes the automobile fuel tank 13 vibrate in the clean water, and pulls the impact bubble removal component to rotate and point to different directions in the automobile fuel tank 13.

[0020] The shaking and bubbling parts of the bubble evacuation mechanism 3 are extended and knocked against the bottom wall of the automobile fuel tank 13, which effectively vibrates the automobile fuel tank 13 and causes the bubbles in the gap on its lower surface to be discharged. This step significantly reduces the misjudgment caused by bubble retention, making the sealing test result more reliable and accurate. The automated bubble evacuation and vibration process reduces the need for manual intervention and improves the test efficiency. The operator only needs to start the equipment to automatically complete the steps of evacuating bubbles and vibrating the automobile fuel tank 13, saving time and labor costs. The shock wave generated by the electric spark of the impact debubbling piece igniting the mixed gas can quickly and violently vibrate the automobile fuel tank 13. The design of the impact debubbling piece facing different directions allows the shock wave to act on the automobile fuel tank 13 in all directions, thereby enhancing the comprehensiveness and adaptability of the detection. The shock wave can act evenly and strongly on various surfaces of the automobile fuel tank 13, ensuring that the retained bubbles on the entire surface of the automobile fuel tank 13 are effectively discharged, thereby significantly reducing the misjudgment caused by retained bubbles and improving the accuracy of sealing detection.

[0021] The tank pressing part includes an auxiliary pressure plate 21 fixedly connected to the auxiliary arm 14, and handle rings 22 for staff to hold are fixedly provided at both ends of the auxiliary pressure plate 21. An electric push rod 25 is fixedly provided below the auxiliary pressure plate 21. The automobile fuel tank 13 is immersed in the clean water of the water tank 12 by extending the telescopic arm of the electric push rod 25.

[0022] A sealing column 31 is fixedly provided at the output end of the telescopic arm of the electric push rod 25, an outer sealing airbag 32 is fixedly provided on the outer wall of the sealing column 31, a middle sealing airbag 33 is fixedly provided below the outer sealing airbag 32, an inner sealing airbag 34 is fixedly provided below the middle sealing airbag 33, the inner sealing airbag 34, the middle sealing airbag 33 and the outer sealing airbag 32 are interconnected, and the inner sealing airbag 34 and the outer sealing airbag 32 are symmetrical with respect to the center line of the middle sealing airbag 33.

[0023] The air inlet end of the outer sealing airbag 32 is fixedly connected to an air supply pipe 29, and the end of the air supply pipe 29 away from the outer sealing airbag 32 is connected to an air supply tank 27 fixedly connected to the side wall of the electric push rod 25. The air supply tank 27 is provided with an air pump and stores air for injecting air into the inner sealing airbag 34, the middle sealing airbag 33 and the outer sealing airbag 32 through the air supply pipe 29 to expand them. A plurality of air injection ports 302 are provided on the outer circle of the lower wall of the sealing column 31, and the air injection ports 302 are interconnected with the air supply pipe 29.

[0024] When the staff puts the automobile fuel tank 13 to be tested into the clean water of the reservoir 12, the automobile fuel tank 13 floats on the water surface. Then, the staff holds the handle ring 22, pulls the position of the electric push rod 25, aligns the telescopic arm of the electric push rod 25 with the fuel filling port of the automobile fuel tank 13, inserts the sealing column 31 into the fuel filling port of the automobile fuel tank 13, and makes the middle sealing airbag 33 just stuck at the position of the fuel filling port of the automobile fuel tank 13. Then, the air pump in the air supply tank 27 works to inject air into the inner sealing airbag 34, the middle sealing airbag 33 and the outer sealing airbag 32 through the air supply pipe 29; After air is injected into the inner sealed airbag 34, the middle sealed airbag 33 and the outer sealed airbag 32, the inner sealed airbag 34, the middle sealed airbag 33 and the outer sealed airbag 32 expand rapidly, and the oil filling port of the automobile oil tank 13 is sealed by the expansion of the inner sealed airbag 34 and the outer sealed airbag 32; Then, the telescopic arm presses down the fuel tank 13 through the operation of the electric push rod 25, and the fuel tank 13 is pressed into the clean water, and air is injected into the fuel tank 13 through the air injection port 302 to increase the air pressure in the fuel tank 13. If there is a leak in the fuel tank 13, bubbles will be ejected from the leak, thereby detecting the tightness of the fuel tank 13.

[0025] The shaking box bubble removal part includes an extension column 35 fixed at the center position of the lower wall of the sealing column 31, and a lifting piston 39 is slidably arranged inside the extension column 35. A shaking box arm 37 penetrating the lower wall of the extension column 35 is fixedly arranged below the lifting piston 39, and a lower pressure plate 38 is fixedly arranged at the bottom of the shaking box arm 37. A spring 304 is sleeved between the lifting piston 39 on the outer wall of the extension column 35 and the extension column 35.

[0026] The shaking box bubble removal part also includes a shaking chamber 306 opened inside the sealing column 31, and a shaking plate 307 is slidably arranged inside the shaking chamber 306. A shaking rope 301 is arranged below the shaking plate 307 and passes through the bottom wall of the shaking chamber 306 and is fixedly connected to the lifting piston 39.

[0027] An external air inlet pipe 305 is slidably provided at the center position of the shaking plate 307, and an air supply port 303 is provided inside the external air inlet pipe 305. The air inlets of the external air inlet pipe 305 and the air supply port 303 are both interconnected with the inner sealed airbag 34. The air outlet of the external air inlet pipe 305 supplies air to the shaking chamber 306, and the air supply port 303 penetrates the bottom wall of the shaking chamber 306 to supply air to the space above the lifting piston 39. The outer wall of the shaking chamber 306 is provided with an air vent 36.

[0028] After the inner sealed airbag 34, the middle sealed airbag 33 and the outer sealed airbag 32 are inflated, part of the air enters the air inlet of the outer air inlet pipe 305 and the air supply port 303, and part of the air is discharged from the air supply port 303 to the space above the lifting piston 39. As the amount of air increases, the lifting piston 39 is gradually pushed to slide downward, and the lifting piston 39 pushes the shaking arm 37 to extend the extension column 35, so that the lower pressure plate 38 is pressed against the inner bottom of the automobile fuel tank 13; A portion of the air is injected into the shaking chamber 306 from the external air inlet pipe 305. As the amount of air under the shaking plate 307 increases, the shaking plate 307 is pushed to slide upward along the external air inlet pipe 305. The shaking rope 301 is pulled up by pushing the shaking plate 307, and the lifting piston 39 is pulled upward to slide a certain distance by the shaking rope 301. After that, when the rising position of the shaking plate 307 exceeds the air vent 36, the air in the shaking chamber 306 is instantly discharged. At the same time, under the downward pulling force of the lifting piston 39, the lifting piston 39 can drive the shaking box arm 37 to slide down again. This is repeated many times to play the role of knocking the automobile fuel tank 13. The shaking box arm 37 is extended and knocked on the bottom wall of the automobile fuel tank 13, effectively vibrating the automobile fuel tank 13 and causing the bubbles in the gap on its lower surface to be discharged. This step significantly reduces the misjudgment caused by bubble retention, making the sealing test result more reliable and accurate. The impact bubble removal component includes a limit seat 43 fixedly connected to the outer wall of the extension column 35, a swing arm 41 is rotatably arranged on the limit seat 43, a drain barrel 42 is fixedly arranged at one end of the swing arm 41 away from the limit seat 43, the drain barrel 42 is provided with a trumpet-shaped drain chamber 49, an ignition chamber 46 connected to the drain chamber 49 is provided inside the swing arm 41, a pull wire 45 passing through the extension column 35 is fixedly arranged at one end of the swing arm 41 close to the limit seat 43, and a pressure-bearing ball head 44 is fixedly arranged at one end of the pull wire 45 away from the limit seat 43.

[0029] The air inlet end of the ignition chamber 46 is connected to an air supply pipe 28, and the end of the air supply pipe 28 away from the ignition chamber 46 is connected to a gas supply tank 26 fixedly connected to the outer wall of the electric push rod 25. The gas supply tank 26 is provided with an air pump and a detonation mixed gas, and the air pump switch in the gas supply tank 26 is set on the inner wall of the handle ring 22 as a control switch 23.

[0030] A conductive wire 47 is fixedly disposed inside the ignition chamber 46 , and conductive plates 48 fixedly connected to the inner wall of the ignition chamber 46 are disposed on the upper and lower sides of the conductive wire 47 . A piezoelectric igniter 24 is disposed at the power supply end of the conductive wire 47 .

[0031] When the lifting piston 39 slides downward, it presses down the pressure-bearing ball head 44, so that the pressure-bearing ball head 44 pulls the pull wire 45, and the pull wire 45 pulls the swing arm 41 to rotate upward, so that the four pressure-discharging barrels 42 of the four impact bubble-discharging parts face the four directions inside the automobile fuel tank 13; Afterwards, the staff member can press the control switch 23 with the finger on the handle ring 22 to control the air pump in the air supply tank 26 to work, and inject the explosive mixed gas into the ignition chamber 46 through the air supply pipe 28. Because the diameter of the air outlet of the ignition chamber 46 is smaller than the diameter of the air inlet of the pressure relief chamber 49, only a small part of the explosive mixed gas injected into the ignition chamber 46 will flow out. The explosive mixed gas can be a mixed gas of oxygen and methane. After that, the staff member presses the piezoelectric igniter 24 with his finger, and the current emitted by the piezoelectric igniter 24 flows along the conductive wire 47, causing an electric spark to occur between the conductive wire 47 and the conductive plate 48, so that the electric spark instantly ignites the deflagration mixture in the ignition chamber 46, causing the deflagration mixture to explode in the ignition chamber 46, and the gas rushes out of the discharge chamber 49 under the impact of the explosion, and the impact force rushes in different directions, so that the shock wave can act evenly and strongly on various surfaces of the automobile fuel tank 13, ensuring that the retained bubbles on the entire surface of the automobile fuel tank 13 are effectively discharged.

[0032] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
