In this process, the brush 7 is used to clean the impurities remaining on the tire due to driving, and then the external dust suction device is controlled to run through the second through hole 6001 to suck the dust cleaned by the brush 7. After the speed measurement is completed, the four lifters 2 are controlled to run together to drive the two support frames 3 to move together, and at the same time drive the new energy vehicle to move downward, so that the wheels of the new energy vehicle contact with the limit plate 6, so that the wheels of the new energy vehicle are separated from the speed measuring roller 5, and then the detector 4 is controlled to drive the limit plate 6 to move up and down, so that the new energy vehicle on the limit plate 6 is The new energy vehicle shakes to test the torque of the new energy vehicle. Then the staff observes the chassis of the new energy vehicle through the gap between the two sets of slopes 1 to detect whether there is any abnormal noise in the vehicle chassis, and judges the problem of the torque of the new energy vehicle through the abnormal noise. It should be noted that in the existing technology, the new energy vehicle torque abnormal noise detection equipment usually adopts a vibration method for detection during the detection process, and observes the vibration of the components on the new energy vehicle chassis with the human eye to judge whether there is a problem with the torque of the new energy vehicle. However, in the process of shaking, since the car is driving, a large amount of impurities will accumulate on the chassis, among which the impurities on the wheels are the most and are the starting point of the vibration, that is, in the process of vibration, the impurities on the wheels and chassis will fall off with the shaking, and the fallen impurities will affect the staff's observation of the chassis, that is, the dust can be quickly cleaned by the above method to reduce the impact of dust on the staff. At the same time, by fast switching, a variety of different types of detections can be performed on the vehicle, and some dust on the new energy vehicle can be cleaned by different detection methods. Example

[0030] On the basis of the above embodiment 1, Figure 4-Figure 8As shown, it also includes a cleaning component, which includes a delivery pipe 101, a dust collection head 102, a dust collection nozzle 103, a connecting pipe 104, a dust collector 105, a storage bin 106, a storage frame 107 and an isolation component; all the support frames 3 are fixedly connected to the delivery pipe 101, and the delivery pipe 101 is provided with four rectangular arrays of dust collection ports 10101; the delivery pipe 101 is connected to three equally spaced dust collection heads 102; the delivery pipe 101 is connected to four rectangular arrays of dust collection nozzles 103; each vacuum nozzle 103 is connected to the corresponding second through hole 6001; the delivery pipe 101 is connected to two symmetrically arranged connecting pipes 104; two symmetrically arranged storage bins 106 are installed on the ground; each storage bin 106 is installed with a vacuum cleaner 105, and each storage bin 106 is slidably connected to two symmetrically arranged storage frames 107; each vacuum cleaner 105 is connected to the corresponding connecting pipe 104; the delivery pipe 101 is connected to two symmetrically arranged isolation components.

[0031] Each isolation component includes a sliding plate 108, a shift rod 109, an isolation net 1010, a connecting plate 1011, a telescopic cloth 1012 and a limiting plate 2 1013; two symmetrically arranged sliding plates 108 are slidably connected to the conveying pipe 101; each sliding plate 108 is provided with eleven equidistantly distributed shift rods 109; each sliding plate 108 is fixedly connected to the isolation net 1010; each sliding plate 108 is fixedly connected to the connecting plate 1011; each connecting plate 1011 is fixedly connected to the telescopic cloth 1012; the other end of the telescopic cloth 1012 is fixedly connected to the connecting pipe 104; each conveying pipe 101 is fixedly connected to two symmetrically arranged limiting plates 2 1013; the limiting plate 2 1013 is in contact with the telescopic cloth 1012.

[0032] Each sliding plate 108 is provided with an electromagnet for cooperating with each other to stretch the retractable cloth 1012 so that the retractable cloth 1012 can collect and guide the cleaned impurities.

[0033] The connection between the sliding plate 108 and the lever 109 is made of rubber material, that is, during the torque noise detection process of the new energy vehicle, after being hit by the lever 109, the lever 109 can move up and down to hit the telescopic cloth 1012.

[0034] The upper part of the lever 109 is a rubber rod, and is provided with a spherical rubber ball for cooperating with the impact on the chassis of the new energy vehicle.

[0035] The sliding plate 108 and the isolation net 1010 are arranged in quick-release contact, which is convenient for replacement and cleaning of residual impurities thereon.

[0036] The retractable cloth 1012 is tilted to one side to guide the cleaned impurities.

[0037] The lower surface of the second limiting plate 1013 is made of rubber material, which is used to fit the telescopic cloth 1012 to reduce the overflow of impurities.

[0038] When the torque of the new energy vehicle is tested for abnormal noise, the detector 4 and the limit plate 6 are operated to drive the new energy vehicle to shake, that is, the vacuum cleaner 105 is controlled to operate, so that the new energy vehicle should shake to produce impurities that fall into the storage box 107 of the storage bin 106. Among them, a small part of the impurities on the chassis of the new energy vehicle enters the delivery pipe 101 through the vacuum head 102, and then enters the connecting pipe 104 through the delivery pipe 101, and enters the vacuum cleaner 105 through the connecting pipe 104, and finally enters the storage box 107 of the storage bin 106. Most of the impurities on the chassis of the new energy vehicle will fall on the telescopic cloth 1012. Since the telescopic cloth 1012 is set to an inclined setting, the impurities will fall along the The retractable cloth 1012 flows close to the dust suction port 10101 opened on the conveying pipe 101, and enters the conveying pipe 101 through the dust suction port 10101, and then enters the connecting pipe 104 through the conveying pipe 101, and enters the dust cleaner 105 through the connecting pipe 104, and finally enters the storage frame 107 of the storage bin 106. The dust on the wheels of the new energy vehicle enters the conveying pipe 101 through the dust suction nozzle 103, and then enters the connecting pipe 104 through the conveying pipe 101, and enters the dust cleaner 105 through the connecting pipe 104, and finally enters the storage frame 107 of the storage bin 106. In this process, at the same time, the detector 4 drives the limit plate 6 to move up and down, and through the limit plate Plate 106 drives the new energy vehicle to vibrate back and forth, that is, during this process, the chassis of the new energy vehicle will hit the lever 109 back and forth, that is, through the impact of the lever 109, the falling of impurities on the chassis is accelerated, and at the same time, the other end of the lever 109 continuously hits the telescopic cloth 1012, and under the action of the shaking, the impurities on the telescopic cloth 1012 are quickly moved close to the dust suction port 10101 to prevent the impurities from accumulating on the telescopic cloth 1012. That is, through the above method, the impurities on the chassis of the new energy vehicle are quickly cleaned. When the chassis makes an abnormal sound, the staff needs to manually release the electromagnet on the sliding plate 108 of the same group, and drive the two sliding plates 108 to move away from each other under the contraction of the telescopic cloth 1012. , so that the sliding plate 108 slides on the conveying pipe 101. Since the slide groove on the conveying pipe 101 is provided with a damping block, the sliding plate 108 moves slowly. At the same time, during the sliding process, the sliding plate 108 drives the lever 109 and the isolation net 1010 to follow the movement, and at the same time, the lever 109 further hits the chassis of the new energy vehicle to further clean the dust on the chassis of the new energy vehicle. When the sliding plate 108 drives the isolation net 1010 to contact the conveying pipe 101, most of the impurities are cleaned up, that is, during the work observation process, the problem of the work being affected by the falling impurities is reduced. At the same time, the impurities are cleaned up in time, which reduces the subsequent cleaning time of the staff and speeds up the detection efficiency.

Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
