Description

Technical Field

[0001] The present invention relates to the technical field of automobile testing, and in particular to a new energy automobile safety testing and flushing operation device. Background Art

[0002] Electric vehicle safety requirements are an important item in the whole vehicle testing of new energy vehicles. Both the national standard and the European standard have put forward corresponding requirements. In the latest electric vehicle safety test, requirements for electric vehicle waterproof safety are put forward. Testing the insulation performance requirements of electric vehicles after the vehicle flushing test is also a very important aspect.

[0003] At present, the flushing test process is generally that the tester wears insulating gloves and insulating shoes to flush the car with a water pipe. Since there are many high-voltage electrical components on the car, including power batteries, drive motors, air compressors, motor controllers, air conditioners, defrosters, etc., there is a risk of electric shock even when the electric car is turned off. For example, the power battery may short-circuit due to water ingress, etc., which poses certain safety hazards. In addition, manual work requires flushing each part of the car in turn, which is inefficient; in addition, manual work can only determine whether the flushing position and interval distance are accurate by visual inspection, and it is impossible to perform operations accurately according to the test requirements. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes a new energy vehicle safety test flushing device, which can quickly and accurately flush the vehicle.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a new energy vehicle safety test flushing operation device, including an insulating floor mat, a flushing bracket and a nozzle;

[0006] The insulating floor mat is arranged on the floor, and a plurality of positioning marks are arranged on the surface;

[0007] The flushing bracket is arranged on the insulating floor mat and comprises a fixed bracket. The fixed bracket is a rectangular parallelepiped frame structure. Nozzles are arranged on four sides of the fixed bracket.

[0008] After the vehicle enters the fixed bracket on the insulating floor mat, the parking position is determined by multiple positioning marks, and then water can be sprayed from all sides through nozzles to fully rinse the exterior of the vehicle.

[0009] The beneficial effects of the above-mentioned new energy vehicle safety test flushing operation device are: the efficiency of the flushing test is improved by flushing the vehicle from multiple directions through the device. And after setting the positioning mark on the ground, it is convenient for the vehicle to park, so that the distance between the vehicle and the nozzle is more accurate, and the test accuracy is improved. In addition, the vehicle is flushed through the device and an insulating mat is set on the ground, which greatly improves the safety of the test.

[0010] Furthermore, an isolation waterproof belt is provided on the insulating floor mat, and the isolation waterproof belt is arranged around the outer side of the flushing bracket.

[0011] The isolation waterproof tape can prevent the flushing water from flowing out of the insulating mat, avoid affecting the surrounding environment, and improve the safety of the device.

[0012] Furthermore, the flushing bracket also includes a movable bracket, and movable movable brackets are provided on four horizontal sides of the fixed bracket, and the plurality of nozzles are respectively arranged on each movable bracket.

[0013] The mobile bracket can move on the four sides of the fixed bracket and move relative to the stopped vehicle to adjust the distance between the nozzle and the vehicle, ensuring that the vehicle is centered between the nozzles on both sides, thereby improving the accuracy of the flushing test.

[0014] Further, the mobile support comprises a mobile frame, a horizontal frame and a vertical frame;

[0015] The four horizontal sides of the fixed bracket are all provided with extension brackets extending outwards, and the extension brackets are provided with guide rails, and the movable frame is movably arranged on the guide rails, and can be close to or away from the fixed bracket;

[0016] The horizontal frame is arranged horizontally, and both ends are movably arranged on the horizontal sides of the movable frame. The vertical frame is arranged vertically, and both ends are movably arranged on the upper and lower sides of the movable frame. The horizontal frame and the vertical frame are both provided with strip holes along the axial direction. The nozzle is movably arranged in the two strip holes, and a position sensor is provided on the nozzle.

[0017] Each mobile frame moves on each extension bracket of the fixed bracket to adjust the distance between the vehicle and avoid mutual interference. After the distance between the vehicle and the position sensor is measured, the horizontal frame and the vertical frame move vertically or horizontally on the mobile frame, thereby driving the nozzle to move up and down and left and right to wash different positions of the vehicle, thereby comprehensively washing all the parts to be tested on the vehicle.

[0018] Furthermore, the extension bracket is also a rectangular parallelepiped frame structure, which is assembled from a plurality of extension rods, the guide rails are arranged on the extension rods, and the movable frame is movably arranged in the guide rails.

[0019] The guide rail is an electric guide rail, which can drive the moving frame to move, thereby adjusting the distance between the moving frame and the vehicle.

[0020] Furthermore, the mobile bracket also includes a slider, which passes through the strip holes of the horizontal frame and the vertical frame in sequence and is slidably connected to the two strip holes. The slider is provided with a through hole connecting the two ends. The nozzle is arranged at one end of the slider and is connected to the water source through a water outlet pipe, and the water outlet pipe passes through the through hole.

[0021] The vertical movement of the horizontal frame can drive the slider to move in the vertical direction in the strip hole of the vertical frame, and the horizontal movement of the vertical frame can drive the slider to move in the horizontal direction in the strip hole of the horizontal frame, thereby driving the nozzle to move up, down, left and right, and wash the vehicle at different positions.

[0022] Furthermore, the nozzle is rotatably connected to the end of the slider via a rotating pin, the slider is also provided with a motor, and the motor is connected to a driving gear, the rotating pin sleeve is provided with a driven gear, and the driving gear is meshed with the driven gear.

[0023] By driving the driving gear to rotate through the motor, the driven gear and the rotating pin can be driven to rotate, thereby driving the nozzle to rotate relative to the slider and adjusting the angle of the nozzle to achieve a better flushing effect, especially for some parts of the vehicle that are blocked or have gaps, where a good flushing effect cannot be achieved in the horizontal direction.

[0024] Furthermore, it also includes a circulating water system, including a sump, a water pump and a water source. The sump is arranged below the insulating floor mat, and the insulating floor mat is provided with a drainage trough connected to the sump. The water inlet end of the water pump is connected to the water source, and the water outlet end is connected to multiple nozzles through an outlet pipe. The sump is connected to the water inlet end of the water pump through a circulating water pipe.

[0025] The water after flushing can flow into the sump through the drainage trough to avoid water accumulation on the insulating mat. At the same time, the water in the sump can enter the water pump through the circulating water pipe and continue to be used for flushing, achieving the effect of recycling and saving water resources.

[0035] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] See also Figures 1 to 4 The present invention provides a new energy vehicle safety test flushing operation device, including an insulating floor mat 10, a flushing bracket 20 and a nozzle 30. After the vehicle drives onto the insulating floor mat 10, the vehicle is flushed through the nozzle 30 on the flushing bracket 20.

[0037] Specifically, the insulating floor mat 10 is arranged on the floor, and a plurality of positioning marks are provided on the surface. The flushing bracket 20 is arranged on the insulating floor mat 10, and includes a fixed bracket 21. The fixed bracket 21 is a rectangular frame structure. Nozzles 30 are provided on the four sides of the fixed bracket 21. In this embodiment, the nozzle adopts a standard test nozzle that meets the IPX5 conditions. After the vehicle drives onto the insulating floor mat 10, it drives into the fixed bracket 21, and the parking position is determined by a plurality of positioning marks. Then, water can be sprayed from all sides through the nozzle to fully flush the outside of the vehicle. By installing positioning marks to determine the position of the vehicle and flushing the vehicle on multiple sides at the same time, the accuracy and work efficiency are greatly improved, and the safety is also greatly improved.

[0038] Specifically, an isolation waterproof belt 11 is provided on the insulating floor mat 10, which is arranged around the outside of the flushing bracket 20 to prevent the water after flushing from flowing out of the insulating floor mat, avoid affecting the surrounding environment and causing leakage, and improve safety.

[0039] Specifically, the flushing bracket 20 further includes a mobile bracket 22, and movable mobile brackets 22 are provided on four horizontal sides of the fixed bracket 21, and a plurality of nozzles 30 are respectively provided on each mobile bracket 22. The mobile bracket 22 can move on four sides of the fixed bracket 21, and move closer to or farther from the stopped vehicle to adjust the distance between the nozzle 30 and the vehicle, so as to ensure that the vehicle is centered between the nozzles on both sides, so as to improve the accuracy of the flushing test. In this embodiment, the distance between the nozzle and the vehicle surface is 3 meters as required by the standard test.

[0040] The mobile bracket 22 includes a mobile frame 221, a horizontal frame 222 and a vertical frame 223. The four horizontal sides of the fixed bracket 21 are all provided with extension brackets 211 extending outward, and the extension brackets 211 are provided with guide rails. The mobile frame 221 is movably arranged on the guide rails and can be close to or away from the fixed bracket 21. The horizontal frame 222 is a rod-shaped structure, which is horizontally arranged and both ends are movably arranged on the horizontal sides of the mobile frame 221. The vertical frame 223 is also a rod-shaped structure, which is vertically arranged and both ends are movably arranged on the upper and lower sides of the mobile frame 221. The horizontal frame 222 and the vertical frame 223 are both provided with strip holes along the axial direction. The nozzle 30 is movably arranged in the two strip holes, and a position sensor is also provided on the nozzle 30.

[0041] Each movable frame 221 can move on each extension bracket 211 of the fixed bracket 21 to adjust the distance between the fixed bracket 21 and the vehicle, and can move on the bracket extending outward to avoid mutual interference. Figure 2 Only one of the moving frames is shown in the figure. After the distance between the vehicle and the position sensor is measured, the moving frame 221 is first moved to adjust the distance, and then the horizontal frame 222 and the vertical frame 223 move vertically or horizontally on the moving frame 221, thereby driving the nozzle 30 to move up and down and left and right to wash different positions of the vehicle, thereby comprehensively washing all the parts to be tested of the vehicle. In this embodiment, in order to facilitate the entry of the vehicle, the bottom of one of the extension brackets is open.

[0042] In this embodiment, the extension bracket 211 is also a rectangular parallelepiped frame structure, which is assembled from a plurality of extension rods. The guide rails are arranged on several extension rods extending outward horizontally. The four corners of the moving frame 221 can be movably arranged in the guide rails, and the guide rails are electric guide rails, which can drive the moving frame 221 to move, so as to quickly and accurately adjust the distance between the nozzle 30 and the vehicle. In addition, the inner walls of the four sides of the moving frame 221 are also provided with guide rails, and the ends of the horizontal frame 222 and the vertical frame 223 are arranged in the guide rails of the moving frame 221, so as to adjust the position of the nozzle 30. Since the electric guide rail is a prior art, it is not described in detail in the specification, nor is it shown in the figure.

[0043] In addition, a slider 225 is also included. The slider 225 passes through the bar holes of the horizontal frame 222 and the vertical frame 223 in sequence and is slidably connected to both bar holes. A limit block is provided on the slider 225. The limit block is fitted with the side of the horizontal frame 222 and the vertical frame 223 that are away from each other, and is used to limit the slider 225 so that it can only move horizontally or vertically to avoid moving forward and backward. The slider 225 is provided with a through hole connecting the two ends. The nozzle 30 is arranged at one end of the slider 225 and is connected to the water source through the water outlet pipe 141. The water outlet pipe 141 passes through the through hole.

[0044] By moving the horizontal frame 222 on the guide rail of the movable frame 221, the slider 225 can be driven to move in the vertical direction in the strip hole of the vertical frame 223. By moving the vertical frame 223 on the guide rail of the movable frame 221, the slider 225 can be driven to move in the horizontal direction in the strip hole of the horizontal frame 222, thereby driving the nozzle 30 to move up, down, left and right, and flushing the vehicle at different positions to ensure that all positions to be tested are flushed.

[0045] Specifically, the nozzle 30 is inserted into the through hole and is rotatably connected to the end of the slider 225 through the rotating pin 31. The slider 225 is also provided with a motor 226, and the motor 226 is connected to a driving gear 227. The rotating pin 31 is fixedly sleeved with a driven gear 311, and the driving gear 227 is meshed with the driven gear 311. The driving gear 227 is driven to rotate by the motor 226, which can drive the driven gear 311 and the rotating pin 31 to rotate, thereby driving the nozzle 30 to rotate relative to the slider 225 to adjust the angle of the nozzle to achieve a better flushing effect, especially for some parts of the vehicle that are blocked, have gaps or edges, horizontal flushing cannot achieve a good effect, and the nozzle needs to be tilted upward or downward at a certain angle.

[0046] Specifically, it also includes a circulating water system, including a sump 13, a water pump 14 and a water source. The sump 13 is arranged below the insulating floor mat 10, and a drainage groove 12 connected to the sump 13 is arranged on the insulating floor mat 10. The water inlet end of the water pump 14 is connected to the water source, and the water outlet end is connected to a plurality of nozzles 30 through a water outlet pipe 141. The sump 13 is connected to the water inlet end of the water pump 14 through a circulating water pipe 131. The flushed water can flow into the sump 13 through the drainage groove 12 to avoid water accumulation on the insulating floor mat 10. At the same time, the water in the sump 13 can enter the water pump 14 through the circulating water pipe 131, so as to continue to be used for flushing, thereby achieving the effect of recycling and saving water resources.

[0047] The working principle of the above-mentioned new energy vehicle safety test flushing operation device is: first move the horizontal frame 222 and the vertical frame 223 in the moving frame 221 on the entrance side to the top and the side to make room for the vehicle to enter. After the vehicle enters, the initial positioning and parking are completed through the positioning mark on the insulating floor mat 10. Then the moving frame 221 determines the distance between the vehicle and the moving frame 221 through the position sensor, and then moves on the extension bracket 211, so as to accurately center the vehicle between the two opposite nozzles. The nozzle 30 starts to flush the vehicle. After completing the flushing of one component, the position of the nozzle is adjusted by moving the horizontal frame 222 and the vertical frame 223 in succession, and then the next component is cleaned. For the edge or blocked position, the motor 226 drives the nozzle 30 to rotate and tilt to ensure the flushing effect.

[0048] By using the above-mentioned new energy vehicle safety test flushing device, the vehicle is flushed through the device and an insulating mat is set on the ground, which does not require manual flushing, greatly improving safety. In addition, the vehicle can be flushed from multiple directions at the same time, which improves the efficiency of the flushing test. By setting positioning marks on the ground, the vehicle can be initially positioned first, and then the nozzle can be driven to move by the moving frame, so that the vehicle can be accurately centered between the nozzles, improving the accuracy of the test.
