Description

Technical Field

[0001] The present invention belongs to the technical field of battery inspection, and in particular relates to bottom battery inspection equipment for new energy vehicles. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or conventional fuels with new onboard power units), integrating advanced technologies in vehicle power control and drive to create vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. Because the core battery of new energy vehicles is located in the underbody, regular underbody inspections are necessary, necessitating the use of underbody battery inspection equipment.

Specifically, the device comprises an abnormal noise inspection plate, wherein the top of the abnormal noise inspection plate is provided with an inspection buffer groove, the inner bottom wall of the inspection buffer groove is provided with an inspection buffer spring, one end of the inspection buffer spring is provided with an inspection observation camera, and the left and right sides of the abnormal noise inspection plate are provided with an inspection auxiliary battery box, the interior of the inspection auxiliary battery box is provided with a battery, the top of the inspection auxiliary battery box is provided with an inspection light board, and the top of the inspection light board is provided with an inspection lighting lamp. This vehicle chassis abnormal noise detection device does not require vehicle maintenance personnel to climb under the vehicle and lift the vehicle to observe the location of the abnormal noise, which not only reduces the workload of vehicle maintenance personnel but also saves the time spent in lifting the vehicle. Although today's vehicle bottom inspection device can achieve the purpose of inspection, its detection area is limited and it cannot achieve detailed inspection of the bottom of the vehicle. At the same time, the device is not very adjustable and cannot be laid flat, which makes it difficult to fold it later and is not conducive to actual operation. At the same time, during the inspection process, mud and sand on the bottom of the car will fall on the observation structure, which is not convenient for processing. The equipment can only be pulled out and cleaned, which is troublesome and time-consuming to operate, and the actual application effect is not good. In order to solve the above problems, there is an urgent need for new energy vehicle bottom battery inspection equipment. Summary of the Invention

[0027] 1. In the present invention, a mobile cleaning component is provided. When the device is actually used, the base is moved to the bottom of the new energy vehicle. At this time, the staff can observe the battery status at the bottom of the vehicle through the convex mirror. During operation, the staff can move the device at any time to change the observation area. At the same time, the angle of the overall telescopic rod can be adjusted through the universal joint to facilitate the operation of the device. During the inspection process, if some debris falls on the convex mirror, the second pull rope can be directly reeled in through the second reel. At this time, one end of the second pull rope can pull the mobile cleaning component sideways. During the lateral movement of the mobile cleaning component, the meshing gear disc can also mesh with the mounting rack to rotate, thereby driving the cleaning disc to rotate. The rotating cleaning disc passes through the surface of the convex mirror, which can achieve cleaning of the convex surface. The convex mirror can be effectively cleaned by removing some debris on the convex mirror, and the convex mirror can be quickly cleaned. At the same time, when used in cold weather, if the convex mirror fogs up during use, the electric heating tube in the cleaning tray can be turned on to increase the temperature, and then the cleaning tray can be used to wipe the convex mirror, which can effectively remove the fog. During observation, the fill light component can also be adjusted for auxiliary lighting to improve the observation effect. Through this design, the overall equipment is light and compact, easy to carry, and can quickly change the inspection area during the inspection process. At the same time, the equipment can be adjusted at an angle according to the use requirements to ensure the inspection effect. At the same time, the convex mirror can be quickly cleaned through external operation, which can effectively remove the dirt and fog adhering to the surface of the convex mirror, greatly improving the actual application effect and detection effect of the equipment.

[0028] 2. In the present invention, an endoscope component is provided inside, so when the device is in use, the endoscope lens can also be opened. The endoscope lens can take high-definition photos of the bottom of the car and transmit the images to the digital display screen in real time. During use, when it is necessary to adjust the observation angle of the endoscope lens, it is only necessary to use the thumb to operate the first wire take-up device to reel in the first pull rope. The first pull rope can pull one end of the mounting shell to deflect it, thereby changing the observation angle of the endoscope lens. When the first wire take-up device is released, the mounting shell will be reset under the action of the torsion spring. Through this design, an additional endoscope structure is used for auxiliary observation of the bottom of the car, which can be combined with the convex mirror to further improve the inspection effect and clarity of the equipment. At the same time, the staff can fine-tune the angle of the endoscope component very conveniently from the outside, so that it can observe a wider area, further improving the application effect of the equipment.

[0029] 3. In the present invention, a mobile component is provided inside, and when the equipment is used, the position of the entire device can be changed by rolling on the ground through the movable wheels. During the observation process, if a certain area needs to be observed at a fixed point, the device needs to be positioned.

A wire groove is provided inside the mounting slider 62, and the first pull rope 15 and the second pull rope 19 both pass through the wire groove.

[0046] The specific implementation method is as follows: when the device is actually used, the base 11 is moved to the bottom of the new energy vehicle. At this time, the staff can observe the battery status at the bottom of the vehicle through the convex mirror 10. During operation, the staff can move the device at any time to change the observation area.

A first pull rope 15 is provided on one side of the bottom of the mounting shell 162, and one end of the first pull rope 15 extends to the inner side of the first wire reel 4.

[0049] The specific implementation method is as follows: when the device is in use, the endoscope lens 161 can also be opened. The endoscope lens 161 can take high-definition photos of the bottom of the car and transmit the images to the digital display screen 2 in real time. During use, when it is necessary to adjust the observation angle of the endoscope lens 161, you only need to use your thumb to operate the first wire take-up device 4 to achieve the winding of the first pull rope 15. The first pull rope 15 can pull one end of the mounting shell 162 to deflect it, thereby changing the observation angle of the endoscope lens 161. When the first wire take-up device 4 is released, the mounting shell 162 will be reset under the action of the torsion spring 164.

[0050] Through this design, an additional endoscope structure is used for auxiliary observation of the bottom of the car, which can be combined with the convex mirror 10 to further improve the inspection effect and clarity of the equipment.

A movable wheel 134 is rotatably installed on the inner side of the wheel frame 133 through a rotating shaft. A plurality of suction cups 14 are provided on the bottom surface of the base 11.

[0052] The specific implementation method is as follows: when using the device, the position of the entire device can be changed by rolling on the ground through the movable wheels 134. During the observation process, if a certain area needs to be observed at a fixed point, the device needs to be positioned. At this time, the base 11 is directly pressed down, and the wheel frame 133 can be deflected during the pressure process, so that the entire moving component 13 will be stored in the bottom groove 12. At the same time, the multiple suction cups 14 on the bottom surface of the base 11 can contact the bottom surface for adsorption, thereby realizing the positioning of the device, avoiding the device from being misplaced during the observation process, and further improving the application effect of the device.

[0053] Working principle: When the device is actually used, the base 11 is moved to the bottom of the new energy vehicle. At this time, the staff can observe the battery status at the bottom of the vehicle through the convex mirror 10. During operation, the staff can move the device at any time to change the observation area. At the same time, the angle of the overall telescopic rod 7 can be adjusted through the universal joint to facilitate the operation of the device. During the inspection process, if some debris falls on the convex mirror 10, the second pull rope 19 can be directly reeled in through the second reel 5. At this time, one end of the second pull rope 19 can pull the mobile cleaning component 9 to move sideways. During the sideways movement of the mobile cleaning component 9, the gear disc is engaged. 92 can also mesh with the mounting rack 20 to rotate, thereby driving the cleaning disk 93 to rotate. The rotating cleaning disk 93 passes over the surface of the convex mirror 10, which can effectively clean the convex mirror 10, remove some debris on the convex mirror 10, and complete the rapid cleaning of the convex mirror 10. At the same time, when used in cold weather, if the convex mirror 10 fogs during use, the electric heating tube in the cleaning disk 93 can be turned on to increase the temperature, and then the cleaning disk 93 can be used to wipe the convex mirror 10, which can effectively remove the fog. During observation, the fill light component 6 can also be adjusted to provide auxiliary lighting to improve the observation effect.

[0054] When the device is in use, the endoscope lens 161 can also be opened. The endoscope lens 161 can take high-definition photos of the bottom of the car and transmit the images in real time to the digital display screen 2. During use, when it is necessary to adjust the observation angle of the endoscope lens 161, it is only necessary to use the thumb to operate the first wire take-up device 4 to achieve the winding of the first pull rope 15. The first pull rope 15 can pull one end of the mounting shell 162 to deflect it, thereby changing the observation angle of the endoscope lens 161. When the first wire take-up device 4 is released, the mounting shell 162 will be reset under the action of the torsion spring 164.

[0055] When the device is in use, the position of the entire device can be changed by rolling it on the ground through the movable wheels 134. During the observation process, if a certain area needs to be observed at a fixed point, the device needs to be positioned. At this time, the base 11 is directly pressed down, and the wheel frame 133 can be deflected during the pressure process, so that the entire moving component 13 will be stored in the bottom groove 12.
