Therefore, they should not be construed as limitations on this utility model. In this embodiment, Figure 2 The horizontal direction is the horizontal direction, and the direction perpendicular to the horizontal direction is the vertical direction.

[0026] As shown in the figure, this utility model discloses a fixing device for spraying a charging port cover, including a first bracket 1 for fixing the charging port cover to be sprayed and a second bracket 3 for fixing the charging port cover to be sprayed in a set position. The first bracket 1 is horizontally arranged, and the second bracket 3 is arranged at an angle to the first bracket 1. In this embodiment, by setting the first bracket 1 horizontally and cooperating with the second bracket 3 which is arranged at an angle to the first bracket 1, it is ensured that the charging port cover can always be in a horizontal position during the spraying process. In this way, charged paint particles can fall vertically and evenly onto the surface of the charging port cover under the action of gravity and achieve uniform coverage, thereby avoiding various paint defects caused by uneven paint after spraying, such as uneven film thickness, runs, and paint smears. At the same time, because of the fixing device of this application, it is only necessary to select an appropriate angle between the first bracket 1 and the second bracket 3 according to the selected position to ensure that the first bracket 1 is always horizontal after installation. Therefore, when using the fixing device of this embodiment for spraying the charging port cover, its fixing position is not limited, and any position on the vehicle body, such as the inner panel of the tailgate, can be selected as the fixing position for the charging port cover.

[0027] In this embodiment, the first bracket 1 includes a fixing plate 10, a locking mechanism mounted on the fixing plate 10, and multiple fixing claws 11. The charging port cover is detachably mounted on the fixing plate 10 via the multiple fixing claws 11. The locking mechanism is used to lock the charging port cover within the multiple fixing claws 11. In this embodiment, the multiple fixing claws 11 are all located above the vertical direction of the fixing plate 10. Each fixing claw 11 has a horizontally arranged insertion section. The charging port cover is installed on the multiple fixing claws 11 by insertion. The insertion directions of the multiple fixing claws 11 are the same. In this embodiment, the fixing claws 11 have an "L" shaped structure, and the fixing plate 10 is rectangular. Their installation directions are consistent as shown in the figure. There are four fixing claws 11 in total, which are respectively located at the four corners of the fixing plate 10. When installing the charging port cover, the four fixing claws 11 are respectively inserted into the mounting holes on the back of the charging port cover to be sprayed, and then locked in conjunction with the locking mechanism to restrict its sliding, thus completing the installation and fixing of the charging port cover.

The sliding post 13 is fixedly installed on the fixed plate 10, the locking baffle 12 is slidably connected to the sliding post 13, and the elastic element I 14 is installed on the sliding post 13. The elastic element I 14 has an elastic force pointing towards the fixed plate 10, and the locking baffle 12 is pressed against the fixed plate 10 under the action of the elastic force of the elastic element I 14. In this embodiment, the locking baffle 12 includes a slider 1201 and a stop block 1202. The slider 1201 is slidably installed on the sliding post 13 and located below the fixed plate 10 in the vertical direction. The stop block 1202 is fixedly installed on the slider 1201. When the locking baffle 12 is not sliding, the upper part of the stop block 1202 extends vertically upward to above the fixed plate 10. As shown in the figure, the elastic element I14 is a spring, and the sliding post 13 is equipped with a nut and a washer to limit the movement of the elastic element I14 and the locking baffle 12. The elastic element I14 uses its own elastic force to press the slider 1201 against the bottom surface of the fixed plate 10. In this embodiment, the stop 1202 is located in the insertion direction of the charging port cover. When installing the charging port cover, the locking baffle 12 is first pulled down so that the charging port cover can be inserted smoothly. Then, under the action of the elastic force of the elastic element I14, the locking baffle 12 moves upward and extends above the fixed plate 10, forming a barrier in the insertion path of the charging port cover. Combined with the protrusion of the charging port cover itself, the charging port cover can be limited and reliably fixed. For ease of operation, the upper part of the stop 1202 is vertically set, and the lower part is bent to form a bend in the entire stop 1202, making operation more convenient. In this embodiment, in order to ensure the stability of the sliding of the locking baffle 12, a guide post 15 is provided on the bottom surface of the fixed plate. The guide post 15 passes through the slider 1201 to guide and limit the sliding of the slider 1201.

[0029] In this embodiment, it also includes, for example, Figure 1 The bracket connecting rod 2 shown is used to connect the fixing plate 10 and the second bracket 3 at an angle. The angle between the first bracket 1 and the second bracket 3 can be achieved in various ways, but using the bracket connecting rod 2 is the simplest and most economical. The bracket connecting rod 2 is bent to the required angle before connecting the fixing plate 10 and the second bracket 3, ensuring that the first bracket 1 and the second bracket 3 can be connected at an angle, thus ensuring that the first bracket 1 is in a horizontal position after installation.

[0030] In this embodiment, the second support 3 includes multiple fixed legs, and the second support 3 is installed at a set position via the multiple fixed legs. In this embodiment, the second support 3 also includes a leg connecting rod 7, and the multiple fixed legs are respectively connected by the leg connecting rod 7 to form a second support 3 with a spatial frame structure; the support connecting rod 2 is connected to the leg connecting rod 7 to ensure the connection between the first support 1 and the second support 3, while also avoiding affecting the normal operation of each fixed leg. The multiple fixed legs include at least a first leg 5 and a second leg 6; the ends of the first leg 5 and the second leg 6 are provided with a limiting part with an "L" shaped structure; the first leg 5 is fixedly set, and the second leg 6 is set in a manner that allows it to rotate around its own axis and move along its own axis in a limited manner. As shown in the figure, in this embodiment, a total of three legs are provided, including two first legs 5 and one second leg 6. The three fixed legs are distributed in a triangle and connected by the leg connecting rod 7, forming an overall frame structure. The first support leg 5 is positioned above the second support leg 6, with the end of the limiting part of the first support leg 5 pointing upwards, while the end of the limiting part of the second support leg 6 points downwards after it is fixed. The second bracket 3 is detachably fixed at a set position using a three-point fixing method. Furthermore, to further enhance the fixing effect, a nut or a reverse ejector pin can be installed on the first support leg 5. This allows the limiting part of the first support leg 5 and the nut or reverse ejector pin to form a clamping fixation, further improving the fixing effect and ensuring the stability of the charging port cover during the painting process.

[0031] In this embodiment, the second support leg 6 further includes a support body 601, a sliding sleeve 603, an elastic element II, and a rotating handle 604. The support leg connecting rod 7 is fixedly connected to the sliding sleeve 603. The limiting part 602 and the rotating handle 604 are respectively disposed at both ends of the axial direction of the support body 601. The support body 601 passes through the sliding sleeve 603 and is slidably connected to the sliding sleeve 603. The elastic element II is sleeved on the support body 601 and located inside the sliding sleeve 603. The elastic element II is used to provide an elastic force II along the axial direction of the support body 601. In this embodiment, the elastic element II is also a spring. The support body 601 passes through the sliding sleeve 603, ensuring that the sliding of the support body 601 can proceed normally. Under the elastic force of the elastic element II, the support body 601 tends to move away from the set position. When fixing, while rotating the rotating handle 604, push the rotating handle 604 towards the set position so that the limiting part 602 is inserted into the hole at the set position. Then, rotate the rotating handle 604 again and release the push on the rotating handle 604. The limiting part 602 of the second support leg 6 then abuts against the set position. Combined with the two fixing points of the first support leg 5, the entire second bracket 3 achieves three-point fixing at the set position. In this embodiment, a reverse ejector pin 9 is also provided at the position of the support leg connecting rod 7 near the second support leg 6. The reverse ejector pin 9, together with the second support leg 6, further improves the installation reliability. In this embodiment, the elastic element II is mainly used to provide elastic force to ensure that the limiting part can be pressed against the set position. Different installation methods can be selected depending on its specific selection. Taking the spring in this embodiment as an example, the elastic element II is integrally sleeved on the support body 601. The end of the elastic element II away from the limiting part is fixed on the support body 601, and the end of the elastic element II near the limiting part is fixed on the inner wall surface of the sliding sleeve 603. In this way, it can be ensured that the limiting part has a tendency to move away from the set position. This is understandable to those skilled in the art and will not be elaborated here.

[0032] This embodiment also includes an electrostatic adsorption ring 4 and an adsorption ring connecting rod 8. The electrostatic adsorption ring 4 is installed on the bracket connecting rod 2 and sleeved on the first bracket 1 via the adsorption ring connecting rod 8. As shown in the figure, the electrostatic adsorption ring 4 is a radially closed annular structure. The electrostatic adsorption ring 4 forms a surrounding enclosure of the first bracket 1 in the horizontal direction as shown in the figure. The electrostatic adsorption ring 4 utilizes the principle of electrostatics to improve the efficiency and quality of painting. Its working principle is that through the action of an electrostatic field, the paint particles in the painting process are charged, thereby adsorbing onto the surface of the object being painted to form a uniform coating. In this embodiment, the setting of the electrostatic adsorption ring 4 ensures that the paint can be more easily adsorbed onto the surface of the charging port cover, further ensuring the painting effect.
