A spraying equipment for electric vehicle frames

Abstract

This utility model relates to the field of electric vehicle frame technology, specifically a painting device for electric vehicle frames. The device starts a servo motor at the top of a crossbar, which drives a sprocket inside the crossbar to rotate. The sprocket drives a chain and a second sprocket to rotate. The chain rotation moves several hanging rods at the bottom, which in turn move a fixed rod and the electric vehicle frame towards the interior of the frame. During this movement, gears at the bottom of the hanging rods mesh with racks on the side wall of the crossbar, causing the fixed rod and the electric vehicle frame to rotate. When the electric vehicle frame reaches the side of the fixed plate, the servo motor at the top is activated, driving a threaded screw inside a groove on one side of the fixed plate to rotate. The threaded screw drives a lifting block to rise and fall continuously, causing the lifting rod to rise and fall. At this time, a paint pump is activated, pumping paint through the connection port into three nozzles for spraying outwards, painting the rotating electric vehicle frame. Excess paint mist falls into a water tank, while paint mist in the air is drawn away by an exhaust fan.

[0002] The electric bicycle frame is the core structure of an electric bicycle, similar to the skeleton of the human body, playing a crucial role in supporting and connecting various components. It not only determines the appearance and structure of the electric bicycle but also directly affects riding performance and comfort. The electric bicycle frame mainly consists of components such as the main frame, rear swingarm, center stand, side stand, rear rack, and handlebars.

[0003] The current method of painting electric vehicle frames involves workers using handheld spray guns, which is not suitable for large-scale painting and has low efficiency. The paint mist during the painting process can also cause harm to workers, which in turn leads to a decrease in the efficiency of electric vehicle frame painting.

[0004] Therefore, we propose a spraying equipment for electric vehicle frames. Utility Model Content

[0023] Example: A spraying device for electric vehicle frames, such as... Figures 1-4 As shown, the device includes a housing 1, an exhaust pipe 2 fixedly installed on one side of the housing 1, circulation ports 3 on both sides of the housing 1 away from the exhaust pipe 2, a crossbar 4 fixedly installed at the top inside the housing 1, a suspension assembly installed inside the crossbar 4, a spraying assembly installed below the suspension assembly on the side away from the exhaust pipe 2, and a water tank 5 below the spraying assembly.

[0024] like Figures 1-4As shown, the suspension assembly includes a servo motor 6. The servo motor 6 is fixedly mounted at the top of the crossbar 4. A sprocket 7 is rotatably connected inside the crossbar 4 and is fixedly connected to the servo motor 6. A chain 8 is meshed with the outside of the sprocket. A sprocket 9 is meshed with the end of the chain 8 away from the sprocket 7. Several suspension rods 10 are fixedly mounted at the bottom of the chain 8. Gears 11 are rotatably connected to the bottom of the suspension rods 10. A toothed groove 12 is formed inside the crossbar 4 near the gear 11. A rack 13 is fixedly mounted inside the toothed groove 12 and meshes with the gear 11. A fixing rod 14 is fixedly mounted at the bottom of the gear 11. A sliding groove 15 is formed on the fixing rod 14. A sliding rod 16 is fixedly mounted inside the sliding groove 15. A hook 17 is slidably connected to the outside of the sliding rod 16. A spring 18 is mounted at the bottom of the hook 17 and is sleeved on the outside of the sliding rod 16. A clip 19 is fixedly installed at the bottom of the fixed rod 14. The gap of the electric vehicle frame is locked in the clip 19. Then, the hook 17 in the sliding groove 15 on one side of the fixed rod 14 is pulled down and locked in other gaps of the electric vehicle frame. At this time, the spring 18 on the slide rod 16 inside the fixed rod 14 releases its elastic force and pushes the hook 17 upward, locking and fixing the electric vehicle frame. The servo motor 6 at the top of the crossbar 4 is started. The servo motor is a G-20 series and drives the sprocket 7 inside the crossbar 4 to rotate. The sprocket 7 drives the chain 8 and the second sprocket 9 to rotate. The rotation of the chain 8 drives the several hanging rods 10 at the bottom to move. The hanging rods 10 drive the fixed rod 14 at the bottom and the electric vehicle frame to move into the body. During the movement, the gear 11 at the bottom of the hanging rod 10 meshes with the rack 13 on the side wall of the crossbar 4 and rotates, driving the fixed rod 14 at the bottom and the electric vehicle frame to rotate.

[0025] like Figures 1-3 As shown, the spraying assembly includes a fixed plate 20. A servo motor 21 is fixedly installed at the top of the fixed plate 20. A groove 22 is provided on the side of the fixed plate 20 away from the housing 1. A threaded screw 23 is rotatably connected inside the groove 22. The threaded screw 23 is fixedly connected to the servo motor 21. A lifting block 24 is threadedly connected to the outside of the threaded screw 23. A lifting rod 25 is fixedly installed on the side of the lifting block 24 away from the fixed plate 20. A connection port 26 is provided on one side of the lifting rod 25. Three nozzles 27 are fixedly installed on the side of the lifting rod 25 away from the fixed plate 20. The three nozzles 27 are connected to the connection port 26. When the servo motor 21 at the top is started (the servo motor is a G-20 series), it drives the threaded screw 23 inside the groove 22 on one side of the fixed plate 20 to rotate. The threaded screw 23 drives the lifting block 24 to rise and fall continuously, and drives the lifting rod 25 to rise and fall. At this time, the paint pump is started to pump paint through the connection port 26 into the three nozzles 27 and spray it outward to spray paint on the rotating electric vehicle frame.

[0026] Working principle: When painting the electric vehicle frame, first connect the servo motor of the device to the power supply, connect the paint pump to the connection port 26 on one side of the lifting rod 25, connect the exhaust pipe 2 on one side of the box 1 to the exhaust fan and turn on the exhaust fan. It should be noted that the paint pump and exhaust fan are common models on the market, and the servo motor is a G-20 series. The gap of the electric vehicle frame is locked on the clip 19, and then the hook 17 in the sliding groove 15 on one side of the fixing rod 14 is pulled down and locked in other gaps of the electric vehicle frame. At this time, the spring 18 on the slide rod 16 inside the fixing rod 14 releases its elasticity and pushes the hook 17 upward, locking and fixing the electric vehicle frame, reducing the shaking of the frame and affecting the painting.

[0027] The servo motor 6 at the top of the crossbar 4 is started, which drives the sprocket 7 inside the crossbar 4 to rotate. The sprocket 7 drives the chain 8 and the second sprocket 9 to rotate. The rotation of the chain 8 drives the several hanging rods 10 at the bottom to move. The hanging rods 10 drive the fixed rod 14 at the bottom and the electric vehicle frame to move into the body. During the movement, the gear 11 at the bottom of the hanging rod 10 meshes with the rack 13 on the side wall of the crossbar 4 and rotates, driving the fixed rod 14 at the bottom and the electric vehicle frame to rotate. When the electric vehicle frame comes to the side of the fixed plate 20, the servo motor 21 at the top is started, which drives the threaded screw 23 inside the slide groove 22 on the side of the fixed plate 20 to rotate. The threaded screw 23 drives the lifting block 24 to rise and fall continuously, driving the lifting rod 25 to rise and fall. At this time, the paint pump is started to pump the paint into the three nozzles 27 through the connection port 26 and spray it outward to paint the rotating electric vehicle frame. Excess paint mist falls into the water tank, and the paint mist in the air is sucked away by the exhaust fan.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
