Description
Technical Field
[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a painting fixture for a split-type rear tailgate. Background Technology
[0002] During the painting process, the car body-in-white undergoes specialized painting processes such as intermediate coat and topcoat. For painting body opening and closing components, such as the tailgate, it is necessary to ensure that the opening and closing components are stably supported relative to the car body and maintain an appropriately restricted opening angle during the painting of the entire interior and exterior surfaces to ensure the accessibility of the painting and the corresponding painting quality.
[0003] Currently, most vehicle designs use a one-piece tailgate structure. Therefore, the design of tailgate painting fixtures primarily considers the support and ease of opening of this type of tailgate. However, for a split tailgate structure that includes a lower tailgate, painting the inner surface requires opening both the tailgate and the lower tailgate separately, lifting the tailgate and laying the lower tailgate flat for painting. When painting the outer surface, both the tailgate and the lower tailgate must be kept slightly open to facilitate painting and prevent the wet paint films from rubbing against each other. Existing painting fixtures cannot meet the painting requirements of split tailgates.
[0004] Therefore, a split-type paint spraying fixture for the rear door needs to be designed to solve the above problems. Utility Model Content
[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a painting fixture for a split-type rear door, which effectively solves the problem that the existing one-piece fixture cannot meet the painting needs of a split-type rear door.

[0030] According to the present invention, a split-type rear door spray painting fixture is provided, such as... Figures 1 to 6 As shown, this split-type tailgate painting fixture is used for painting the split-type tailgate of a vehicle. The fixture includes a connecting support assembly, a first opening limit assembly, and a second opening limit assembly. The split-type tailgate of the vehicle includes a first tailgate at the top and a second tailgate at the bottom. These two tailgates require different painting methods depending on the situation. For example, when painting the inner surface, both the first and second tailgates need to be opened, so that the first tailgate is lifted and the second tailgate is laid flat. When painting the outer surface, both the first and second tailgates need to be kept at a small opening angle to facilitate painting (the second state mentioned below refers to the open state of the tailgate when painting the inner surface, while the first state refers to the tailgate being kept at a small opening angle when painting the outer surface).
[0031] In the following description, reference will be made to Figures 1 to 6 This section describes the detailed structure of the connecting support assembly, the first opening limit assembly, and the second opening limit assembly of the paint spraying fixture for the split-type rear door.
[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting support assembly includes a connecting support rod 101, a first limiting support rod 102, and a connecting rod 103. The connecting support rod 101 is positioned at the location of the split-type tailgate. Specifically, the connecting support rod 101 can be formed into a long strip structure and can be arranged laterally, so that both ends of the connecting support rod 101 can be fixed to the inner panel under the D-pillar of the vehicle body, thereby enabling the first opening limiting assembly and the second opening limiting assembly to achieve limiting and fixing. The first limiting support rod 102 abuts against the first tailgate. The first limiting support rod 102 can provide support for the first opening limiting assembly when the first tailgate is closed, and maintain the tailgate at a small opening angle, facilitating painting of the outer surface of the tailgate.
[0033] like Figure 3As shown, the first opening limiting assembly includes a second limiting support rod 201. The connecting support rod 101 has a mounting hole 104 for connecting the second limiting support rod 201. The second limiting support rod 201 can provide support for the first rear door when it is opened, facilitating the limiting of the first rear door and maintaining its current position, thus facilitating painting of the inner surface of the rear door. The first end of the second limiting support rod 201 can be connected to the mounting hole 104 in the connecting support rod 101, and this connection can be detached using connecting bolts. The second end of the second limiting support rod 201 is provided with a limiting pin, which can abut against the first rear door.
[0034] like Figure 4 As shown, the second opening limiting assembly may include a limiting plate 301 slidably connected to the connecting rod 103. The second opening limiting assembly is connected to the second rear door via the second connecting plate 305, and the second opening limiting assembly is slidably connected to the limiting plate 301 via the connecting rod 103. Specifically, a sliding pin 106 is provided at the end of the connecting rod 103, and a slide rail is provided on the limiting plate 301. Through the cooperation of the sliding pin 106 and the slide rail, the operator can open or close the second rear door through the second opening limiting assembly to facilitate painting operations.
[0035] This split-type tailgate painting fixture, through the cooperation of a connecting support component, a first opening limit component, and a second opening limit component, enables painting operations on the inner and outer surfaces of the split-type tailgate. The three separate components allow for quick installation, saving on-site installation time. This split-type tailgate painting fixture is reusable and can be replaced and cleaned in modules, reducing painting production costs. The first and second opening limit components enable painting of both the first and second tailgates, and the fixture provides self-limiting control when the first and second tailgates open and close, eliminating the need for external support, saving time and effort, and improving painting efficiency.
[0036] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the first limiting support rod 102 and the connecting rod 103 are rotatably mounted on the connecting support rod 101. To accommodate different car models and tailgate heights, the first limiting support rod 102 is rotatably mounted on the connecting support rod 101. Similarly, to limit the opening and closing of the second tailgate, the connecting rod 103 is rotatably mounted on the connecting support rod 101. Furthermore, to accommodate different car models and tailgate heights, the lengths of the first limiting support rod 102 and the second limiting support rod 201 can be reasonably selected according to actual conditions.
[0037] Preferably, such as Figure 1As shown in the embodiment, in order to ensure that the rotatable first limiting support rod 102 is fixed, the connecting support assembly may also include a rotation limiting member 107. The rotation limiting member 107 may be formed as a cylindrical support member. The height of the rotation limiting member 107 may be selected as needed, so that the first limiting support rod 102 can abut against the first rear door.
[0038] Preferably, such as Figure 5 and Figure 6 As shown in the embodiment, when the split-type rear door is in the painting process, the painting fixture for the split-type rear door allows it to switch between a first state and a second state. In the first state, the first rear door needs to maintain a small opening angle for easy painting; therefore, a first limiting support rod 102 abuts against the first rear door to provide support and limit its movement. The second rear door is then limited by the connecting rod 103 and the limiting plate 301. In the second state, the second limiting support rod 201 is installed in the mounting hole 104 and abuts against the first rear door. The length of the second limiting support rod 201 is greater than the length of the first limiting support rod 102, thus enabling the first rear door to be supported and limited even with a larger opening angle.
[0039] Preferably, such as Figures 4 to 6 As shown, in this embodiment, the limiting plate 301 has a limiting slide rail, which may include a straight slide rail 302 and a bent slide rail 303 connected to each other. The straight slide rail 302 and the bent slide rail 303 can together form a J-shaped slide rail, and the bent slide rail 303 is used for limiting. The end of the connecting rod 103 is provided with a sliding pin 106, and the connecting rod 103 is slidably disposed in the limiting slide rail through the sliding pin 106.
[0040] Furthermore, when the split-type rear door is in the first state, the sliding pin 106 is located at the end of the bent slide 303 away from the straight slide 302. When the split-type rear door is in the second state, the sliding pin 106 is located at the end of the straight slide 302 away from the bent slide 303.
[0041] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the connecting support rod 101 includes a first crossbar 1011 and a second crossbar 1012. The first crossbar 1011 and the second crossbar 1012 are provided with pivot shafts 105. The first limiting support rod 102 and the connecting rod 103 are connected to the pivot shafts 105. To ensure sufficient stability of the first and second opening limiting components, the connecting support rod 101 adopts a double crossbar design, with the pivot shaft 105 positioned between the two crossbars to ensure a stable connection. To correspond to the first rear door located at the top and the second rear door located at the bottom, two pivot shafts 105 are used. The two pivot shafts 105 are respectively located at the top and bottom of the connecting support rod 101 and are respectively connected to the first limiting support rod 102 and the connecting rod 103.
[0042] Preferably, such as Figure 1 and Figure 2 As shown in the embodiment, to further improve the stability of the connection, a positioning plate 1013 and a connector 1014 are provided at the end of the connecting support rod 101. The connector 1014 is disposed on the positioning plate 1013, and the connecting support rod 101 is disposed at the location of the split-type rear door through the positioning plate 1013 and the connector 1014, specifically at both ends of the inner panel under the D-pillar of the vehicle body. To facilitate connection and fixation, the connectors 1014 at both ends of the connecting support rod 101 can be connecting bolts and positioning pins, respectively.
[0043] Preferably, such as Figure 3 As shown, in this embodiment, the first opening limiting component may further include a first pull ring 202. A first connecting plate 203 is provided at the end of the first pull ring 202, and the first pull ring 202 is connected to the first rear door via the first connecting plate 203. The first connecting plate 203 may be provided with connecting bolts and connected to the first rear door via the connecting bolts. The first pull ring 202 drives the first rear door to open and close, so that the second limiting support rod 201 can abut against the first rear door, thereby keeping the first rear door in a second state.
[0044] Preferably, such as Figure 1 and Figure 2 As shown, in the embodiment, the second opening limiting component may further include a second pull ring 304. The end of the second pull ring 304 is provided with a second connecting plate 305. The second pull ring 304 is connected to the second rear door through the second connecting plate 305. The second pull ring 304 drives the second rear door to open and close, so that the second rear door can be limited by the second opening limiting component.
[0045] Preferably, such as Figures 4 to 6 As shown, in this embodiment, the end of the limiting plate 301 is connected to the second connecting plate 305.
[0046] The assembly and use of the paint spraying fixture for the split-type tailgate is as follows: the connecting support assembly is installed on the inner panel under the D-pillar of the vehicle body through the connecting bolts and positioning pins at both ends of the connecting support rod 101; when the first tailgate and the second tailgate are in the first state, the first tailgate is supported by the first limiting support rod 102, so that the first tailgate is at a small opening angle, while the connecting rod 103 is located at the end of the bending slide 303, so that the second tailgate is limited; when the first tailgate and the second tailgate are in the second state, the first tailgate is supported by the second limiting support rod 201, so that the first tailgate can maintain the opening angle, while the connecting rod 103 is located at the end of the straight slide 302, so that the second tailgate can maintain the opening angle. The operator can open and close the first and second rear doors by using the first pull ring 202 and the second pull ring 304. When opening the second rear door, the second rear door is rotated slightly upwards, causing the connecting rod 103 to fall due to gravity and thus disengage from the limit state, thereby allowing the second rear door to open and slide to the end of the linear slide 302, achieving the limit state in the second state.
[0047] This split-type tailgate painting fixture, through the cooperation of a connecting support component, a first opening limit component, and a second opening limit component, enables painting operations on the inner and outer surfaces of the split-type tailgate. The three separate components allow for quick installation, saving on-site installation time. The fixture has a simple overall structure, is reusable, and can be replaced and cleaned in modules, reducing painting production costs. The first and second opening limit components enable painting of both the first and second tailgates, and the fixture provides self-limiting control when the tailgates open and close, eliminating the need for external support, saving time and effort, and improving painting efficiency.
[0048] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
