Description

Technical Field

[0001] The present application relates to the technical field of automotive painting tools, and particularly to a protective tooling for the rear door of an automobile. Background Art

[0002] During the automotive painting production process, due to operations such as painting, gluing, sanding, and inspection, the rear door of the automobile needs to be opened and closed one or more times. Because different parts inside the rear door of the automobile need to be operated, a rear door tooling is required to fix and support the rear door of the automobile. In related structures, a rod-shaped structure with a fixed height is usually used to support the rear door of the automobile. When different support heights are required for the rear door of the automobile, different rear door toolings need to be replaced, which is rather troublesome to use. Moreover, the load-bearing capacity of the rod-shaped rear door tooling is relatively weak. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a protective tooling for the rear door of an automobile that can adjust the support height according to the support height requirements of the rear door of the automobile and has a relatively strong load-bearing capacity.

[0004] A protective tooling for the rear door of an automobile, the protective tooling for the rear door of the automobile includes a main rod, a support rod, and a connecting rod group. The main rod has an installation position, and a first connection position and a second connection position located on both sides of the installation position along the length direction of the main rod. One end of the support rod is movably connected to the installation position, and the other end is used to connect to the rear anti-collision beam sheet metal of the automobile. One end of the connecting rod group is fixedly connected to the first connection position, and the other end is movably matched with the support rod. The second connection position is used to connect to the rear door of the automobile; wherein, when the rear door of the automobile is pressed against the second connection position, under the action of the gravity of the rear door of the automobile, the main rod rotates around the installation position and drives the connecting rod group to be locked and connected to the support rod.

[0005] In one embodiment, the connecting rod group includes a positioning member, a connecting rod, and a transfer rod. One end of the connecting rod is connected to the main rod through the positioning member, and the other end is movably matched with the support rod through the transfer rod, or is locked and connected to the support rod.

[0006] In one embodiment, the positioning member has a plurality of positioning posts, and the positioning posts are used for plugging and matching with the positioning holes of the rear door of the automobile.

[0007] In one embodiment, one end of the transfer rod is connected to the connecting rod, and a hook is provided at the other end. The hook is movably hooked on the side wall of the support rod, and when, under the action of an external force, the transfer rod moves away from the support rod along with the connecting rod, the hook can move to abut against the support rod to limit the continuous movement of the connecting rod.

[0008] In one embodiment, a bent portion is provided at one end of the transfer rod close to the connecting rod. The bent portion is perpendicular to the connecting rod and is welded to the connecting rod.

[0009] In one embodiment, a mounting seat is provided at the second connection position, and a mounting hole is provided on the mounting seat. The mounting seat is used to abut against the tailgate of the car, and the mounting hole is used for fasteners to pass through and connect the mounting seat to the tailgate of the car.

[0010] In one embodiment, the mounting seat is configured as an L-shaped bent plate.

[0011] In one embodiment, the main rod is further provided with a handle, which is located on a side of the first connection position away from the installation position, and the handle is used for a user to hold.

[0012] In one embodiment, the automobile tailgate protection tooling also includes a pin shaft, a first hole is opened at the installation position, a second hole is opened at one end of the support rod close to the installation position, and the pin shaft is passed through the first hole and the second hole so that the main rod can rotate around the pin shaft and be connected to the support rod.

[0013] In one of the embodiments, a plurality of supporting feet are provided at one end of the support rod away from the installation position, and the plurality of supporting feet are respectively arranged at an angle to the support rod.

[0014] Compared with the prior art, the automobile tailgate protection tooling provided by the present application has a main rod with the connection between the mounting position and the support rod as a fulcrum to form a lever structure. Furthermore, when the automobile tailgate is crimped to the second connection position, under the gravity of the automobile tailgate, the main rod rotates around the mounting position, the second connection position moves downward along the gravity direction, and the first connection position drives the connecting rod group to move upward until the connecting rod group moves to the support rod and is locked and connected, thereby limiting the connecting rod group and the main rod from continuing to move, so that the automobile tailgate protection tooling forms a stable support structure to support the automobile tailgate. In this way, the automobile tailgate protection tooling can adjust the position of the main rod and lock it according to the height of the automobile tailgate, and the automobile tailgate protection tooling in the locked state has a strong load-bearing capacity because a stable support structure is formed between the support rod, the main rod and the connecting rod group.

[0027] Please refer to Figure 1 and Figure 2 , this application provides an automobile tailgate protection tooling 100. The automobile tailgate protection tooling 100 includes a main rod 10, a support rod 20 and a connecting rod group 30. The main rod 10 has a mounting position 11, and a first connection position 12 and a second connection position 13 located on both sides of the mounting position 11 along the length direction of the main rod 10. One end of the support rod 20 is movably connected to the mounting position 11, and the other end is used to connect to the automobile rear anti-collision beam sheet metal. One end of the connecting rod group 30 is fixedly connected to the first connection position 12, and the other end is movably matched with the support rod 20. The second connection position 13 is used to connect to the automobile tailgate; wherein, when the automobile tailgate is pressed against the second connection position 13, under the gravity of the automobile tailgate, the main rod 10 rotates around the mounting position 11 and drives the connecting rod group 30 to be locked and connected to the support rod 20.

[0028] It should be noted that the locking connection of the connecting rod group 30 to the support rod 20 means that there is no further relative movement between the connecting rod group 30 and the support rod 20. It can be understood that the main rod 10 forms a lever structure with the connection point of the installation position 11 and the support rod 20 as the fulcrum. Further, when the automobile tailgate is pressed against the second connection position 13, under the action of the gravity of the automobile tailgate, the main rod 10 rotates around the installation position 11, the second connection position 13 moves downward along the gravity direction, and the first connection position drives the connecting rod group 30 to move upward until the connecting rod group 30 moves to be locked and connected to the support rod 20, thereby restricting the continuous movement of the connecting rod group 30 and the main rod 10, so that the automobile tailgate protection tooling 100 forms a stable support structure to support the automobile tailgate. In this way, the automobile tailgate protection tooling 100 can automatically adjust the position of the main rod 10 according to the height of the automobile tailgate and lock itself. Moreover, for the locked-state automobile tailgate protection tooling 100, due to the stable support structure formed among the support rod 20, the main rod 10 and the connecting rod group 30, the load-bearing capacity is strong.

[0029] Optionally, the main rod 10, the support rod 20 and the connecting rod group 30 are all configured as cold-drawn round steel of Q235 with a diameter of 12 mm.

[0030] As Figures 1 to 3 shown, the second connection position 13 is provided with a mounting seat 131, the mounting seat 131 is provided with a mounting hole 132, the mounting seat 131 is used for abutting against the automobile tailgate, and the mounting hole 132 is used for a fastener to pass through and connect the mounting seat 131 to the automobile tailgate.

[0031] Exemplarily, in one embodiment, the mounting seat 131 is configured as an L-shaped bent plate. The sides of the L-shaped bent plate are respectively used for abutting against two adjacent sides of the automobile tailgate, and two end plates of the L-shaped bent plate are respectively provided with mounting holes 132. The fastener is configured as a bolt, and the bolt passes through the mounting hole 132 and threadedly connects the L-shaped plate to the automobile tailgate.

[0032] The connecting rod group 30 includes a positioning member 31, a connecting rod 32 and a transfer rod 33. One end of the connecting rod 32 is connected to the main rod 10 through the positioning member 31, and the other end is movably matched with the support rod 20 or locked and connected to the support rod 20 through the transfer rod 33.

[0033] Further, the positioning member 31 has a plurality of positioning posts 311, and the positioning posts 311 are used for plugging and matching with the positioning holes of the automobile tailgate. The plugging and matching of the positioning posts 311 and the positioning holes of the automobile tailgate play a positioning role, which is convenient for quickly connecting the automobile tailgate protection tooling 100 to the required position of the automobile tailgate.

[0034] Exemplarily, in one embodiment, the positioning member 31 is configured to be rod-shaped and is made of cold-drawn round steel of Q235 with a diameter of 12 mm. The two side walls on the middle part of the positioning member 31 are respectively welded to the connecting rod 32 and the main rod 10, and the two ends of the positioning member 31 are respectively bent toward the side close to the main rod 10 to form two positioning posts 311. In this way, the structure of the positioning member 31 is simple and convenient for processing. Wherein, the distance between the central axes of the two positioning posts 311 is 100 mm, and the depth of the insertion fit between the positioning post 311 and the positioning hole of the vehicle tailgate is 15 mm.

[0035] In one embodiment, as Figure 1 and Figure 2 shown, one end of the transfer rod 33 is connected to the connecting rod 32, and the other end is provided with a hook 331. The hook 331 is movably hooked on the side wall of the support rod 20. And when under the action of an external force, when the transfer rod 33 moves away from the support rod 20 following the connecting rod 32, the hook 331 can move to abut against the support rod 20 to limit the continuous movement of the connecting rod 32.

[0036] Specifically, as Figure 1 and 2 shown, taking the first connection position 12 being on the left side of the installation position 11 and the second connection position 13 being on the right side of the installation position 11 as an example, the process of the transfer rod 33 and the support rod 20 changing from the movable cooperation state to the locked connection state is introduced: when the vehicle tailgate is pressed against the second connection position 13, under the gravity of the vehicle tailgate, the main rod 10 rotates clockwise around the installation position 11, and the main rod 10 drives the connecting rod group 30 to move away from the support rod 20 through the first connection position 12 until the hook 331 moves to abut against the support rod 20 and limits the continuous movement of the connecting rod 32.

[0037] In other embodiments, a chain (not shown in the figure) can also be used to replace the transfer rod 33. Under the gravity of the vehicle tailgate, the main rod 10 rotates clockwise around the installation position 11, and the main rod 10 drives the chain to move away from the support rod 20 through the first connection position 12 until the chain is tightened and limits the continuous movement of the connecting rod 32.

[0038] As Figure 1 and Figure 2 shown, one end of the transfer rod 33 close to the connecting rod 32 is provided with a bent portion 332. The bent portion 332 is perpendicular to the connecting rod 32 and is welded to the connecting rod 32. The bent portion 332 is used to increase the welding area with the connecting rod 32, so as to be more firmly welded to the connecting rod 32.

[0039] Please refer to Figures 1 to 4, the main rod 10 is also provided with a handle 14. The handle 14 is located on the side of the first connection position 12 away from the installation position 11, and the handle 14 is for the user to hold. In this way, the user can apply a force to the main rod 10 by holding the handle 14, so that the main rod 10 rotates around the installation position 11.

[0040] Optionally, in one embodiment, the handle 14 is in the form of a ring with a hollow middle, so that it is convenient for the user to hold. Or, in another embodiment, the handle 14 can also be configured in the form of an armrest with one end suspended, as long as it is convenient for the user to hold.

[0041] Please refer to Figure 1 , Figure 2 and Figure 5 , the automobile tailgate protection tooling 100 further includes a pin shaft (not shown in the figure). The installation position 11 is provided with a first hole 111. One end of the support rod 20 close to the installation position 11 is provided with a second hole 21. The pin shaft passes through the first hole 111 and the second hole 21, so that the main rod 10 is rotatably connected to the support rod 20 around the pin shaft.

[0042] Optionally, please refer to Figure 1 , Figure 2 and Figure 5 , the installation position 11 is configured as a steel plate with a thickness of 5 mm. The first hole 111 is opened on the steel plate with a thickness of 5 mm. One end of the support rod 20 close to the installation position 11 is configured as a pin shaft seat 23. The pin shaft seat 23 is provided with a notch 231 and two second holes 21 respectively communicating with the notch 231. The steel plate with a thickness of 5 mm is clamped in the notch 231, and the first hole 111 communicates with the two second holes 21. The pin shaft sequentially passes through one of the second holes 21, the first hole 111 and the other second hole 21. In this way, the wall surface of the notch 231 can limit the installation position 11, so that the connection between the installation position 11 and the support rod 20 is more firm.

[0043] Please refer to Figure 1 and Figure 2 , one end of the support rod 20 away from the installation position 11 is provided with a plurality of feet 22, and the plurality of feet 22 are respectively arranged at an angle with the support rod 20. By providing the plurality of feet 22, the support rod 20 can be more stably connected to the automobile rear anti-collision beam sheet metal.

[0044] Optionally, in one embodiment, the number of the feet 22 is configured to be two. Of course, in other embodiments, the number of the feet 22 can also be three, four or five, etc., which can be specifically set according to requirements and will not be listed one by one here.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0046] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
