Description

Technical Field

[0001] The utility model relates to the technical field of deflector processing, in particular to a spraying device for a rear deflector of an automobile. Background Art

[0002] In order to reduce the lift generated by a car when driving at high speed, car designers have made improvements to the car's appearance, tilting the entire body forward and downward to create downward pressure on the front wheels, and changing the rear end to a short and flat shape to reduce the negative air pressure acting from the roof to the rear and prevent the rear wheels from floating. In addition, they have installed a downward-sloping connecting plate under the front bumper of the car. The connecting plate is connected to the front skirt of the car body, and a suitable air inlet is opened in the middle to increase airflow and reduce the air pressure under the car. This connecting plate is called a deflector.

[0003] During the spraying process of the automobile deflector, the deflector needs to be placed on the workbench. In the prior art, Patent No. CN209663597U discloses an automobile deflector spraying device, which includes a slide that can move back and forth on one side of the operating table, a column fixed on the slide, a transverse telescopic mechanism installed on the upper end of the column, and a spray head connected to the spray pipe installed on the end of the transverse telescopic mechanism; a fixed baffle and a mounting frame are provided on the other side of the operating table, a screw nut pair is installed on the mounting frame, a movable baffle is fixed on the nut of the screw nut pair, and a magnetic seat and a magnet block are respectively provided on the opposite surfaces of the movable baffle and the fixed baffle; the spray head faces the workpiece to be sprayed below. The spray head provided in the utility model can be moved back and forth, left and right and adjusted as needed, and is also provided with a fixed splint and a movable splint, a magnet block and a magnetic seat to clamp the workpiece to be sprayed. Clamping and spraying are fast and convenient, and have good practical performance;

[0004] The above-mentioned technical solution allows the deflector plates to be clamped at both ends during use, facilitating spraying. However, when this technical solution is implemented, the contact points between the ends of the deflector plates and the magnet block and the magnetic base cannot come into contact with the material being sprayed in the spray head. This results in blind spots during spraying of the deflector plates, necessitating a secondary spraying process at both ends of the deflector plates in the subsequent process, affecting the efficiency of spraying large quantities of deflectors. To address this issue, we propose a spraying device for automotive rear deflectors. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown, a spraying device for a rear spoiler of an automobile comprises a base plate 1, a lifting frame 2 being fixedly mounted on one end of the upper surface of the base plate 1, a first electric telescopic rod 3 being fixedly mounted on the upper end of the lifting frame 2, a spraying head 4 being movably mounted on the end of the first electric telescopic rod 3, a rectangular plate being fixedly mounted on the upper surface of the base plate 1, two sets of mounting plates 5 being provided on the rectangular plate, one set of mounting plates 5 being fixedly connected to the outer wall of the end of the rectangular plate, and the other set of mounting plates 5 being slidably connected to the upper surface of the rectangular plate, a movable groove 12 being formed through the upper ends of the two sets of mounting plates 5, and a movable component being provided inside the movable groove 12;

[0029] The movable assembly includes an elastic member 18 fixedly installed at the center position inside the movable groove 12. A movable rod 16 is passed through the elastic member 18. One end of the movable rod 16 is provided with a driving structure, and the other end is provided with a clamping structure.

[0030] The main structure in this technical solution is similar to the main structure of the automobile deflector spraying device disclosed in Patent No. CN209663597U, wherein the base plate 1, lifting frame 2, first electric telescopic rod 3, spray head 4, mounting plate 5, etc. in this technical solution are the same as the operating table, column, horizontal telescopic mechanism, spray head 4 and fixed baffle in this technical solution. When the deflector needs to be sprayed, the two ends of the deflector can be fixed by the clamping structure provided on the upper end of the mounting plate 5. At the same time, the deflector can be driven to rotate horizontally or tilted under the action of the driving structure. Then, with the cooperation of the spray head 4, the two ends of the deflector can be sprayed, which can avoid the need for secondary spraying at the position where the deflector contacts the clamping structure, thereby improving the efficiency of the device in spraying the deflector.

[0031] like Figure 4 and Figure 5 As shown, the driving structure includes a driven gear 13 rotatably connected to the outer wall of the mounting plate 5, and the driven gear 13 is coaxially arranged with the movable groove 12. A third electric telescopic rod 14 is fixedly mounted on the inner wall of the driven gear 13, and the output end of the third electric telescopic rod 14 is movably connected to the outer wall of the end of the movable rod 16. The outer wall of the mounting plate 5 is also rotatably mounted with a driving gear 15 meshing with the driven gear 13;

[0032] The two driving structures provided on the outer wall of the mounting plate 5 can drive the movable rod 16 to rotate. When the two movable rods 16 rotate synchronously, the guide plate clamped between the two sets of clamping structures can be driven to rotate synchronously. At this time, the spray head 4 can spray the main body of the guide plate. After the main part of the guide plate is sprayed evenly, one end of the guide plate is removed from the clamping structure. At this time, the third electric telescopic rod 14 in the driving structure provided at the other end of the guide plate is retracted, so that the movable rod 16 is in a tilted state. Under the action of the clamping structure provided at the end of the movable rod 16, the guide plate as a whole is in a tilted state. Then, when the driven gear 13 rotates under the drive of the driving gear 15, the movable rod 16 in the tilted state drives the guide plate to rotate in a conical shape. At this time, the spray head 4 can spray evenly on the end of the guide plate originally clamped by the clamping structure. Similarly, through the cooperation of another set of driving structures and the clamping structure, the other end of the guide plate can be sprayed, thereby avoiding the occurrence of spraying dead corners on the guide plate.

[0033] like Figure 6As shown, the clamping structure includes a connecting plate 19 fixedly connected to the end of the movable rod 16, and the two ends of the connecting plate 19 are respectively fixedly installed with fixed plates 17. The outer wall of the connecting plate 19 is located between the two fixed plates 17 and two symmetrically arranged extrusion plates 20 are slidably installed. A plurality of return springs 21 are arranged between the extrusion plate 20 and the fixed plate 17, and the two ends of the return spring 21 are respectively fixedly connected to the corresponding positions on the fixed plate 17 and the extrusion plate 20; the end of the guide plate is inserted between the two extrusion plates 20, and the return spring 21 arranged between the fixed plate 17 and the extrusion plate 20 is deformed and then contracted. Under the action of the multiple return springs 21, the end of the guide plate can be squeezed tightly by the two extrusion plates 20.

[0034] like Figure 3 As shown, an adjusting gear 11 is fixedly installed on the upper end of the spray head 4, and a rack plate 10 is slidably installed on the outer wall of the output end of the first electric telescopic rod 3 at a position corresponding to the adjusting gear 11, and the rack plate 10 is meshed with the adjusting gear 11. A second electric telescopic rod 9 is fixedly installed on the first electric telescopic rod 3 at a position corresponding to the end of the rack plate 10, and the output end of the second electric telescopic rod 9 is fixedly connected to the end of the rack plate 10; the user can control the second electric telescopic rod 9 to make the rack plate 10 drive the adjusting gear 11 to rotate, and the adjusting gear 11 is coaxially arranged and fixedly connected to the rotating shaft at the upper end of the spray head 4. The adjusting gear 11 can drive the spray head 4 to tilt when it rotates, which can be used to fine-tune the position of the spray head 4 on the guide plate.

[0035] like Figure 1 As shown, protective plates 6 are provided on both sides of the rectangular plate, and the lower ends of the protective plates 6 are slidably connected to the outer walls of both sides of the rectangular plate, and the upper end surface of the bottom plate 1 is fixedly installed with a support rod 23 used in conjunction with the protective plate 6; the protective plate 6 can slide on both sides of the rectangular plate to adjust its position, wherein the support rod 23 can support the protective plate 6, so that the protective plate 6 can stably maintain a vertical protective state after sliding to the corresponding position.

[0036] like Figure 2 As shown, the outer walls on both sides of the rectangular plate are provided with a slide groove 7, and a slider 8 is slidably installed inside the slide groove 7, and the lower end of the protective plate 6 is rotatably connected to the slider 8; the protective plate 6 is adjusted to the position on both sides of the rectangular plate by sliding the slider 8 in the slide groove 7, wherein the protective plate 6 can be rotated and laid flat when not in use, and the protective plate 6 can be slid to block and protect the area between the two sets of mounting plates 5 when needed.

[0037] like Figure 6As shown, a plurality of guide rods 22 are fixedly installed on the outer wall of one side of the extrusion plate 20 close to the fixed plate 17. The guide rods 22 are arranged inside the return spring 21 and the other end is slidably connected to the fixed plate 17. When the extrusion plate 20 is squeezed, the guide rods 22 slide relative to the fixed plate 17. Under the action of the guide rods 22, the force direction of the return spring 21 can be single, thereby avoiding irreversible deformation of the return spring 21 after long-term use.

[0038] The working principle of the utility model is as follows: when in use, the two ends of the semi-finished deflector used at the rear of the car are clamped between the clamping structures provided at the upper ends of the two sets of mounting plates 5. The two driving structures provided on the outer walls of the mounting plates 5 can drive the movable rods 16 to rotate. When the two movable rods 16 rotate synchronously, the deflector clamped between the two sets of clamping structures can be driven to rotate synchronously. At this time, the spray head 4 can spray the main body of the deflector. After the main part of the deflector is evenly sprayed, one end of the deflector is taken out of the clamping structure. At this time, the position The third electric telescopic rod 14 in the driving structure provided at the other end of the deflector is retracted, so that the movable rod 16 is in an inclined state. Then, under the action of the clamping structure provided at the end of the movable rod 16, the deflector as a whole is in an inclined state. Then, when the driven gear 13 rotates under the drive of the driving gear 15, the movable rod 16 in the inclined state drives the deflector to rotate in a conical shape. At this time, the spray head 4 can spray evenly on the end of the deflector originally clamped by the clamping structure. Similarly, through the cooperation of another set of driving structures and the clamping structure, The other end of the guide plate is sprayed to avoid the occurrence of a spraying dead angle on the guide plate, wherein the end of the guide plate is inserted between the two extrusion plates 20, and the return spring 21 arranged between the fixed plate 17 and the extrusion plate 20 is deformed and contracted. Then, under the action of multiple return springs 21, the end of the guide plate can be squeezed tightly by the two extrusion plates 20. Among them, under the action of the guide rod 22, the force direction of the return spring 21 can be single, thereby avoiding the return spring 21 from being irreversibly deformed after long-term use. During the process of spraying the deflector, the user can also adjust the second electric telescopic rod 9 to make the rack plate 10 drive the adjusting gear 11 to rotate. The adjusting gear 11 is coaxially arranged with the rotating shaft at the upper end of the spray head 4 and is fixedly connected. The adjusting gear 11 can drive the spray head 4 to tilt when rotating, and can be used to fine-tune the position of the spray head 4 on the deflector for spraying. In the process of spraying, the protective plates 6 arranged on both sides of the rectangular plate slide and are supported by the support rod 23 to prevent paint sprayed out of the spray head 4 from splashing.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
