[0002] When repairing the doors of a family car or motorhome, the paint on the dents and lines caused by the impact is often polished off first, and then the door is initially repaired using sheet metal. After the door is repaired, it is often necessary to apply putty to the dents and lines on the door, and then the car is subsequently painted.

[0003] However, the existing fixing devices for automobile door repair still have certain defects when used. In the prior art, the fixing devices for automobile doors are often unable to be adjusted autonomously. At the same time, paint fragments and dust debris generated by grinding and sheet metal on the doors need additional cleaning, which reduces the work efficiency of technicians. After applying putty to the door, it is often necessary to use a baking lamp to bake the putty. Since the baking lamp dries the putty through radiation, the radiation cannot be effectively shielded in the prior art, and the radiation may also harm the technicians.

[0015] Beneficial effects of the present invention: 1. The design of the slide groove and the electric slider allows the car door to be effectively translated, and the design of the clamping assembly driven by the motor allows the car door to be effectively rotated, so that the device can be effectively adjusted after clamping the car door, avoiding the disadvantage of the prior art that the car door often needs to be removed when applying putty to the car door, effectively improving the maintenance efficiency of the car door. At the same time, the slide groove and the electric slider slide to adjust the relative position of the car door and the lighting lamp, so that the technician can effectively observe the depressions and textures at different positions on the car door, which is convenient for the technician to find the position on the car door that needs to be puttyed more efficiently, and the rotation of the car door driven by the motor can also enable the technician to observe a wider range of positions and find the position on the car door that needs to be puttyed faster.

[0016] 2. Through the connection of the external air pump and the setting of the nozzle, the nozzle sprays water on the car door, which can wash away the stains caused by the sheet metal on the car door. At the same time, the motor drives the car door to rotate through the clamping assembly. The rotation of the car door will also make the water flow down from the car door faster, which promotes the cleaning of the car door by the device. The air pump blows air to the car door through the inclined hole, which can also promote the water flow to flow down from the car door faster, effectively improving the efficiency of the water flow to clean the paint debris and dust caused by grinding and sheet metal on the car door. At the same time, it avoids the need for additional cleaning of the car door in traditional technology, greatly improving the working efficiency of the device.

[0017] 3. Through the setting of the lifting plate and the winding cloth, the translation of the slider can accelerate the drying speed of the putty, and the winding cloth can effectively block the gap caused by the sliding of the slide frame, thereby effectively preventing the radiation emitted by the baking lamp from being reflected by the water in the hollow of the base, and promoting the lifting plate to effectively block the radiation emitted by the baking lamp. The raising and lowering of the lifting plate can effectively block the radiation emitted by the baking lamp on the one hand, and on the other hand, it can also effectively block the water sprayed on the car door by the nozzle to prevent the water sprayed on the car door from splashing around. The winding cloth can absorb impurities such as paint fragments and dust debris blocked by the filter plate on the one hand, and on the other hand, it can effectively block the radiation emitted by the baking lamp, effectively reducing the damage of the radiation of the baking lamp to the technicians.

[0018] 4. After the water flows down, it will be filtered by the filter plate and enter the hollow part of the base. The setting of the filter plate can effectively block impurities such as paint fragments and dust debris, which is convenient for the subsequent cleaning of impurities on the filter plate and discharged from the hollow part inside the base through the outlet pipe. The filter plate can filter out the paint fragments, dust and debris washed down by the water flow, and the water discharged from the outlet pipe can still be recycled.

[0019] 5. The setting of the airbag can, on the one hand, cushion the contact between the rubber pad and the car door, and on the other hand, the airbag can strengthen the force when the rubber pad fits the car door through the ventilation of the air pump, thereby effectively clamping the car door. In this process, the rubber pad can, on the one hand, protect the airbag, and on the other hand, the expansion of the airbag makes the rubber pad clamp the car door with greater force, thereby increasing the friction between the car door and the rubber pad, thereby making the car door more stable during the clamping process and preventing sliding or deviation.

[0020] 6. On the one hand, the air pump can provide an effective force for the rubber pad to clamp the car door, and on the other hand, it can also enable the inclined holes to effectively promote the circulation of air on the car door. The inclined holes promote air circulation on both sides of the car door. On the one hand, it can blow off some paint fragments and dust impurities on the car door, and promote the water sprayed by the nozzle to wash away the remaining paint fragments and dust impurities on the car door. On the other hand, it can promote the drying of the car door and the drying of putty.

[0021] 7. The setting of the lifting plate can, on the one hand, effectively block the water sprayed on the car door by the nozzle to prevent splashing, and on the other hand, it can also effectively block the radiation emitted by the baking lamp. Secondly, the lifting plate can also be used to place the container of putty when the technicians are applying putty. BRIEF DESCRIPTION OF THE DRAWINGS

The baking lamp 6 is a radiation lamp, so that the putty is dried from the inside to the outside. The light of the lighting lamp 8 on the car door can enable the technician to effectively find the position where the putty needs to be applied, which greatly improves the maintenance efficiency of the car door.

[0035] As a technical optimization scheme of the present invention, the air pump clamping assembly includes a rotating joint 11 connected to the output end of the external air pump, the rotating joint 11 is fixedly connected and connected with a conduit 26, the end of the conduit 26 away from the rotating joint 11 is fixedly connected to the U-shaped plate 13, the U-shaped plate 13 is located on the opposite side of the two vertical plates 9, the conduit 26 is connected with two U-shaped tubes 14, the two U-shaped tubes 14 are symmetrically arranged at the upper and lower ends of the U-shaped plate 13, a rotating gear 12 is fixedly sleeved on the conduit 26, the rotating gear 12 is rotatably connected in the vertical plate 9, the rotating gear 12 is meshedly connected with a driving gear 25, the side of the vertical plate 9 is fixedly connected with a motor 10, the output shaft of the motor 10 is fixedly connected to the rotating shaft of the driving gear 25, the rotation speed of the motor 10 is relatively slow, on the one hand to enable the technicians to observe the car door more carefully and effectively, on the other hand to make the water sprayed by the nozzle 7 more effective in flushing the car door, and at the same time can also reduce the splashing range of the water flow impacting the car door.

[0036] As a technical optimization solution of the present invention, the end of the U-shaped tube 14 away from the conduit 26 is connected to an air groove arranged in the U-shaped plate 13, and the air groove is slidably sleeved with a T-shaped piston 27, and the vertical end of the piston 27 is provided with an air bag 17, and the side of the air bag 17 away from the piston 27 is fixedly connected with a rubber pad 16 for increasing friction, and the air bag 17 is connected to a connecting pipe 28 provided at the vertical end of the piston 27, and the connecting pipe 28 is connected to the U-shaped tube 14 through the air groove. The provision of the rubber pad 16 prevents the sharp edges and corners at the welding point between the door outer panel and the window guide groove from damaging the air bag 17, and at the same time, when the rubber pad 16 contacts the sharp edges and corners at the welding point between the door outer panel and the window guide groove, the sharp edges and corners penetrate into the rubber pad 16, and then the rubber pad 16 generates a tighter force on the door, which plays a significant optimization role in preventing the door from sliding and deviating.

[0037] As a technical optimization scheme of the present invention, a plurality of inclined inclined holes 18 are provided on the side of the U-shaped plate 13 away from the conduit 26, and the inclined holes 18 are connected to the air groove. The distance between the connecting point of the inclined holes 18 and the air groove and the side of the air groove away from the U-shaped tube 14 is greater than the thickness of the piston 27. The inclination angle of the inclined holes 18 is guided from the air groove to the opposite side of the two symmetrical plate sections of the U-shaped plate 13. The two air pump clamping components are symmetrically arranged on the opposite sides of the two vertical plates 9. On the one hand, the air pump can provide an effective force for the rubber pad 16 to clamp the car door, and on the other hand, it can also enable the inclined holes 18 to effectively agitate the circulation of air for the car door. The inclined holes 18 promote air circulation on both sides of the car door. On the one hand, it can blow off some paint fragments and dust impurities on the car door, and promote the water sprayed by the nozzle 7 to wash away the paint fragments and dust impurities remaining on the car door. On the other hand, it can promote the drying of the car door and the drying of putty.

[0038] As a technical optimization solution of the present invention, both sides of the top wall plate of the base 1 are provided with a slide groove 23 with an inverted T-shaped cross section, and the two slide grooves 23 are slidably connected with an electric slider 24, which is fixedly connected to both sides of the bottom of the slide frame 2, and is located on the two bottom frames of the slide frame 2 adjacent to the winding cloth 21. The arrangement of the electric slider 24 and the slide groove 23, on the one hand, enables the position of the slide frame 2 to be effectively adjusted, and on the other hand, it can also promote the scraper 22 and the winding cloth 21 to fully and effectively clean the filter plate 4.

[0039] As a technical optimization solution of the present invention, a placement groove 29 is opened on the wall panel near the hollow part at the top of the base 1, and the filter plate 4 is placed in the placement groove 29. The filter plate 4 is clamped between the base 1 and the slide frame 2 through the slide groove 23 and the electric slider 24. The setting of the placement groove 29 and the filter plate 4 can enable the slide frame 2 to effectively clamp the filter plate 4, and then the filter plate 4 can effectively filter the water sprayed on the car door by the nozzle 7.

[0040] As a technical optimization solution of the present invention, the end of the winding cloth 21 away from the slide frame 2 is fixedly connected to a winding roller, and springs are provided at both ends of the winding roller. The end of the spring away from the winding roller is fixedly connected to the storage rack 20, and the winding roller is rotatably connected to the opposite side of the two storage racks 20 on the same side of the base 1. The arrangement of the storage rack 20 and the spring enables the winding roller to effectively store the winding cloth 21, and secondly enables the scraper 15 to scrape off the adsorbed paint fragments and dust debris on the winding cloth 21, and then collect them through the collection box 19.

[0041] As a technical optimization solution of the present invention, leakage grooves 30 are provided at both ends of the top of the base 1, and the leakage grooves 30 are connected to the collecting box 19. The collecting box 19 is detachably arranged on the side of the base 1, and the collecting box 19 and the storage rack 20 are located on the same side of the base 1. A scraper strip 15 is fixedly connected to the wall panel at the top of the leakage groove 30 away from the hollow part of the base 1, and the scraper strip 15 abuts against the winding cloth 21. The setting of the scraper strip 15 can, on the one hand, clean the winding cloth 21, and on the other hand, effectively block the radiation emitted by the baking lamp 6.

[0042] As a technical optimization scheme of the present invention, a lifting plate 3 is provided on the outer side of the sliding frame 2 for lifting, a guide rail is provided on the outer side of the sliding frame 2, a lifting slider is provided on the inner side of the lifting plate 3, and the lifting plate 3 is installed on the outer side of the sliding frame 2 by means of the guide rail and the lifting slider. A water outlet pipe for drainage is provided at the bottom of the hollow part of the base 1, and a valve is provided on the water outlet pipe. The water outlet pipe is located on the side of the base 1 away from the telescopic rod 5. The setting of the lifting plate 3 can, on the one hand, effectively block the water sprayed on the car door by the nozzle 7 to prevent splashing, and on the other hand, can also effectively block the radiation emitted by the baking lamp 6. Secondly, the lifting plate 3 can also be used to place a container filled with putty when the technician applies putty.

[0043] When the present invention is in use, the welding point between the outer door panel of the automobile and the window guide groove after the sheet metal is clamped in two air pump clamping assemblies, and the welding point between the outer door panel and the window guide groove is first placed between the two U-shaped plates 13, and then the external air pump is turned on. The external air pump inflates the inside of the conduit 26 through the rotary joint 11. As the air pump inflates, after the air pump inflates, the gas enters the air groove through the conduit 26 and the U-shaped tube 14. After the gas enters the air groove, the gas in the air groove increases. On the one hand, it will cause the piston 27 to move toward the direction of the rubber pad 16, and on the other hand, it will also cause the gas to enter the airbag 17 through the connecting pipe 28, thereby causing the airbag 17 to expand.

[0044] After the piston 27 moves toward the rubber pad 16, after the piston 27 moves to the point where the inclined hole 18 is connected to the air groove, the gas will flow out through the inclined hole 18. After the gas flows out through the inclined hole 18, the paint, debris and dust removed during the grinding of the sheet metal can be blown off. Through the inclined design of the inclined hole 18, the gas can act more fully on both sides of the door outer panel, thereby promoting the cleaning effect of the gas on the door outer panel. After the airbag 17 is inflated, the piston 27 descends so that the rubber pad 16 and the welding place between the door outer panel and the window guide groove fit together. After the airbag 17 is inflated, on the one hand, it can buffer the contact between the rubber pad 16 and the door, and on the other hand, the airbag 17 can strengthen the force of the rubber pad 16 and the door when they fit together through the ventilation of the air pump, so that the door is effectively clamped. In this process, the rubber pad 16 can protect the airbag 17 on the one hand, and on the other hand, the expansion of the airbag 17 makes the force of the rubber pad 16 clamping the door greater, thereby increasing the friction between the door and the rubber pad 16, thereby making the door more stable during the clamping process and preventing sliding and deviation.

[0045] After the door is clamped, the motor 10 is started, so that the output shaft of the motor 10 drives the driving gear 25 to rotate, and the driving gear 25 drives the rotating gear 12 to rotate, so that the rotating gear 12 drives the U-shaped plate 13 to rotate through the conduit 26, and the rotation of the U-shaped plate 13 drives the door to rotate effectively. After the door rotates, the lifting plate 3 is controlled to rise and the nozzle 7 is turned on. After the nozzle 7 is turned on, the door will be effectively sprayed with water, and the water sprayed by the nozzle 7 on the door can wash away the stains caused by the sheet metal on the door. At the same time, the motor 10 drives the door to rotate through the clamping assembly, and the rotation of the door will also make the water flow down from the door faster, which promotes the cleaning of the door by the device. The air pump blows air to the door through the inclined hole 18, which can also promote the water flow to flow down from the door faster, effectively improving the efficiency of the water flow to clean the paint debris and dust caused by grinding and sheet metal on the door. In this process, the lifting plate 3 can also effectively shield the water sprayed on the door by the nozzle 7 by the lifting plate 3, preventing the water sprayed on the door by the nozzle 7 from splashing around. After flowing down, the water will be filtered by the filter plate 4 and enter the hollow part of the base 1, and then be discharged from the hollow part inside the base 1 through the outlet pipe. The filter plate 4 can filter the paint fragments, dust and debris washed by the water flow, and the water discharged from the outlet pipe can still be recycled.

[0046] After the car door is rinsed clean, the nozzle 7 is closed and the heating lamp 6 is turned on. At this time, the car door is still rotating driven by the motor 10, and the gas blown out by the air pump is still blowing on the car door through the inclined hole 18. The baking of the heating lamp 6 can evaporate the residual water stains on the car door, thereby effectively drying the car door. The rotation of the car door can also make the heating lamp 6 bake the car door more evenly, which promotes the drying of the car door; the gas blowing on the car door through the inclined hole 18 can also accelerate the evaporation of water stains on the car door, further promoting the drying of the car door. In this process, the lifting plate 3 can effectively block the radiation emitted by the heating lamp 6, effectively reducing the damage of radiation to technicians.

[0047] After the car door is dried, turn off the baking lamp 6 and turn on the lighting lamp 8, then put down the lifting plate 3. Before painting the car door, putty needs to be applied to the concave part of the car door. At this time, place the container with putty on the top of the lifting plate 3, and then drive the car door to rotate by the motor 10. With the illumination of the lighting lamp 8, the technician can more conveniently find the concave part and texture on the car door. After finding the concave part and texture, turn off the motor 10 to stabilize the car door on the device, so that the technician can apply putty to the concave part and texture on the car door, which is convenient for the subsequent painting work. After applying putty to the concave part of the car door, control the lifting plate 3 to rise, and turn on the baking lamp 6 at the same time, so that the baking lamp 6 can effectively dry the applied putty. The baking lamp 6 makes the putty dry from the inside to the outside, and the air pump can quickly dry the external putty through the inclined hole 18, so that the drying efficiency of the putty is effectively improved. In this process, the lifting plate 3 can also effectively block the radiation emitted by the baking lamp 6.

[0048] When observing the depressions and lines on the door through the lighting lamp 8, the relative position of the door and the lighting lamp 8 is adjusted by sliding the electric slider 24 in the slide groove 23, so that the technician can effectively observe the depressions and lines at different positions on the door. In this process, when the electric slider 24 slides in the slide groove 23, the slide frame 2 will translate on the base 1 under the drive of the electric slider 24, and the movement of the slide frame 2 on the base 1 will also drive the winding cloth 21 and the scraper 22 to move on the filter plate 4. The movement of the winding cloth 21 will absorb impurities such as paint fragments and dust debris blocked on the filter plate 4, and can also effectively absorb the water stains remaining on the filter plate 4, while the scraper 22 will effectively remove impurities such as paint fragments and dust debris stuck on the filter plate 4 to prevent the filter plate 4 from being blocked, and at the same time, it can also make the winding cloth 21 more effective in absorbing impurities. After the reeling cloth 21 absorbs the impurities, when the slide frame 2 is reset, the spring on the storage rack 20 drives the reeling roller to rotate effectively. In this process, the side of the reeling cloth 21 that absorbs impurities such as paint chips and dust debris will abut against the scraper bar 15, so that the scraper bar 15 can effectively scrape off the impurities such as paint chips and dust debris absorbed on the reeling cloth 21, and also scrape off some water stains absorbed on the reeling cloth 21. After being scraped off by the scraper bar 15, the impurities such as paint chips and dust debris will enter the drain groove 30, so that the impurities such as paint chips and dust debris enter the collection box 19 through the drain groove 30. The scraped water stains can effectively promote the impurities such as paint chips and dust debris to enter the collection box 19. After the collection box 19 is full of impurities such as paint chips and dust debris, the collection box 19 is removed and the impurities such as paint chips and dust debris in the collection box 19 are cleaned, and then the collection box 19 is reinstalled on the side of the base 1.

[0049] The translation of the sliding frame 2 can also enable the putty applied on different positions of the car door to be specifically baked using the baking lamp 6, thereby accelerating the drying speed of the putty. Due to the sliding of the sliding frame 2, a gap is generated between the two sides of the base 1 and the sliding frame 2, and the rolling cloth 21 can effectively block the gap in this process, thereby effectively preventing the radiation emitted by the baking lamp 6 from being reflected by the water in the hollow part of the base 1, and promoting the lifting plate 3 to effectively block the radiation emitted by the baking lamp 6.
