Description

Technical Field

[0001] This utility model relates to the field of automotive tooling technology, and in particular to a tailgate support rod for automotive assembly. Background Technology

[0002] In modern automobile manufacturing, the vehicle painting workshop undertakes the crucial process of applying PVC sealant and intermediate topcoat to the car body. This process aims to enhance the car body's sealing performance by applying PVC sealant, preventing the intrusion of external factors such as moisture and dust, while using the intermediate topcoat to improve the texture and durability of the car body's appearance. However, to ensure the smooth progress of these painting operations, technicians typically need to first lift the hood and tailgate to a certain angle to obtain sufficient operating space. During this process, support rods are used to support the lifted tailgate. These support rods are made of high-strength materials, possessing excellent load-bearing capacity and stability, reliably supporting the tailgate and preventing it from accidentally closing due to gravity during the painting process, thereby ensuring the safety of the operators and the consistency of the painting quality.

[0003] To adapt to different back doors, the support rod is usually made telescopic. When the overall length is too long, the small upper diameter makes it easy to bend or break. However, the existing support rod can only be discarded as a whole and is inconvenient to replace individually, which is not very practical. Utility Model Content

[0004] The purpose of this utility model is to provide a tailgate support rod for automobile assembly, which aims to solve the technical problem that the support rod in the prior art can only be discarded as a whole when damaged, and is inconvenient to replace individually, resulting in low practicality.

[0005] To achieve the above objectives, this utility model provides a tailgate support rod for automotive assembly, comprising a cylindrical rod, a lifting assembly, a displacement rod, a U-shaped component, a Y-shaped component, and an installation assembly. The lifting assembly is slidably connected to the cylindrical rod, the displacement rod is connected to the cylindrical rod, and the installation assembly is connected to the lifting assembly. The U-shaped component and the Y-shaped component are respectively fixedly connected to the cylindrical rod and the displacement rod.

[0006] The installation assembly includes a connecting pipe, a sliding member, a deformation unit, and a locking device. The connecting pipe is fixedly connected to the lifting assembly and has a sliding groove, a slot, and a through hole. The sliding member is slidably connected to the sliding groove and has a groove. The displacement rod is slidably connected to the slot and has a locking groove. The locking device is slidably connected to the through hole, and all locking devices are adapted to the groove and the locking groove. The deformation unit is fixedly connected to the sliding member.

[0007] The deformation unit includes multiple springs, one end of each spring is fixedly connected to the sliding member, and the other end of each spring is fixedly connected to the connecting pipe. The multiple springs are evenly distributed along the axial centerline of the connecting pipe.

[0008] The sliding component includes a slip ring and a force-applying block. The slip ring is slidably connected to the slide groove, and the force-applying block is fixedly connected to the slip ring.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 ,in Figure 1 This is a structural schematic diagram of the tailgate support rod for automobile assembly according to this utility model. Figure 2 This is a partial structural cross-sectional view of the tailgate support rod for automobile assembly according to this utility model. Figure 3 This is the utility model Figure 1 Enlarged view of the local structure at point A. Figure 4 This is the utility model Figure 2 Enlarged view of the local structure at point B.

[0020] This utility model provides a tailgate support rod for automobile assembly, including a cylindrical rod 101, a lifting assembly, a displacement rod 102, a U-shaped component 103, a Y-shaped component 104, and a mounting assembly. The lifting assembly is slidably connected to the cylindrical rod 101, the mounting assembly is connected to the lifting assembly, and the U-shaped component 103 and the Y-shaped component 104 are fixedly connected to the cylindrical rod 101 and the displacement rod 102, respectively.

[0021] The installation assembly includes a connecting pipe 105, a sliding member, a deformation unit, and a locking device 106. The connecting pipe 105 is fixedly connected to the lifting assembly. The connecting pipe 105 has a sliding groove 113, a slot 114, and a through hole 115. The sliding member is slidably connected to the sliding groove 113 and has a groove 116. The displacement rod 102 is slidably connected to the slot 114 and has a locking groove 117. The locking device 106 is slidably connected to the through hole 115, and the locking device 106 is adapted to both the groove 116 and the locking groove 117. The deformation unit is fixedly connected to the sliding member.

[0022] The deformation unit includes multiple springs 107, one end of each spring 107 is fixedly connected to the sliding member, and the other end of each spring 107 is fixedly connected to the connecting pipe 105. The multiple springs 107 are evenly distributed along the axial centerline of the connecting pipe 105.

[0023] In this specific embodiment, during actual use, the relative distance between the displacement rod 102 and the cylinder rod 101 is adjusted by the lifting assembly, thereby adjusting the overall length. Then, the U-shaped part 103 and the Y-shaped part 104 are placed into the corresponding process holes in the automobile to complete the support. When the displacement rod 102 is bent or broken, it can be disassembled and reinstalled using the mounting assembly. Specifically, the sliding member is slid, causing the spring 107 to deform, aligning the groove 116 with the through hole 115. Then, the displacement rod 102 is pulled... The shift rod 102 moves the locking device 106, causing it to slide within the through hole 115 and move into the groove 116. A new shift rod 102 is then inserted into the slot 114, aligning the locking groove 117 with the through hole 115. The sliding member is then released, causing the spring 107 to reset and the sliding member to reset. The sliding member then moves the locking device 106 into the corresponding locking groove 117 to complete the locking. This method solves the technical problem in the prior art where the support rod can only be discarded as a whole when damaged, making it inconvenient to replace individually and resulting in low practicality.

[0024] The sliding member includes a slip ring 108 and a force-applying block 109. The slip ring 108 is slidably connected to the slide groove 113, and the force-applying block 109 is fixedly connected to the slip ring 108. The force-applying block 109 is located at one end of the slip ring 108 away from the multiple springs 107, and the force-applying block 109 has an anti-slip opening 118.

[0025] In this specific embodiment, the force-applying block 109 can more easily drive the slip ring 108 to slide in the slide groove 113. The movement of the slip ring 108 causes the groove 116 to align with the through hole 115 or the slip ring 108 to move against the locking device 106. The anti-slip opening 118 can play an anti-slip role.

[0026] Secondly, the lifting assembly includes a slide rod 110 and a gripper. The cylinder rod 101 has an opening 119, multiple limiting ports 120 and multiple guide ports 121. The slide rod 110 is slidably connected to the cylinder rod 101, the gripper is fixedly connected to the slide rod 110, and the guide ports 121 connect the corresponding limiting ports 120 to the opening 119.

[0027] In this specific embodiment, when adjusting the height, the grip is lifted upwards, causing the slide bar 110 to move. After the grip moves to the designated position, the grip is rotated so that it is placed inside the opening 119. Then, the height of the grip is adjusted, and then the grip is moved from the corresponding guide opening 121 to the corresponding limiting opening 120 so that the grip contacts the bottom of the limiting opening 120.

[0028] Meanwhile, the gripping component includes a gripping rod 111 and a block 112. One end of the gripping rod 111 is fixedly connected to the slide rod 110, and the other end of the gripping rod 111 is fixedly connected to the block 112. The gripping rod 111 contacts the corresponding limiting port 120.

[0029] In this specific embodiment, the grip rod 111 is used for gripping by the user, and the block 112 can limit the movement of the hand.

[0030] In the application of this utility model, a tailgate support rod for automotive assembly is used. The relative distance between the displacement rod 102 and the cylindrical rod 101 is adjusted via the lifting assembly to adjust the overall length. Then, the U-shaped component 103 and the Y-shaped component 104 are placed into the corresponding process holes in the automotive assembly to complete the support. When the displacement rod 102 is bent or broken, it can be disassembled and reinstalled using the mounting assembly. Specifically, the sliding component is slid, causing the deformation unit to deform, aligning the groove 116 with the through hole 115. Then, the displacement rod 102 is pulled... 02. The displacement rod 102 drives the locking device 106 to move, causing the locking device 106 to slide within the through hole 115 and avoid the groove 116. A new displacement rod 102 is then inserted into the slot 114, aligning the locking groove 117 with the through hole 115. Then, the sliding member is released, and the deformation unit resets, causing the sliding member to reset. The sliding member then drives the locking device 106 to insert into the corresponding locking groove 117 to complete the locking. This method solves the technical problem in the prior art where the support rod can only be discarded as a whole when damaged, making it inconvenient to replace it individually and resulting in low practicality.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
