Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and particularly relates to a support robotic arm for an automobile trunk lid. Background Technique

[0002] An automobile trunk support rod usually refers to a trunk hydraulic support rod, which is an elastic element with gas and liquid as the medium, mainly playing the role of supporting and stabilizing the trunk. The trunk support rod of a vehicle is an important automobile component. With its stable and reliable supporting force, improved usability and safety, it brings great convenience to the daily life of car owners. However, the existing automobile trunk support rods still have some defects and deficiencies in some aspects that need to be improved:

[0003] For example, a waterproof support rod for an electric tailgate of an automobile with the application number CN202220500701.1, which relates to the technical field of electric tailgate support rods. The waterproof support rod for the electric tailgate of the automobile includes a first waterproof box, a mounting component and a limiting component. A second waterproof box is arranged on the first waterproof box, and the first waterproof box is slidably mounted inside the second waterproof box. The mounting component includes a support rod body, a mounting rod, a mounting plate and a hinged mounting rod. This waterproof support rod for the electric tailgate of the automobile can effectively increase the waterproof effect of the support rod body during use, avoid damage caused by water ingress into the support rod body, and thus can reduce property losses. It can also separate the first waterproof box and the second waterproof box, which not only facilitates the maintenance of the support rod body, but also facilitates the disassembly and replacement of the first waterproof box and the second waterproof box, making it convenient for workers to repair.

[0004] For the support rod in the above document, most of them cannot clean the outside of the support rod. During the use of the support rod, dust will adhere to the outside, and the dust will cause wear on the rod body position of the support rod during use, thus affecting the normal operation of the support rod;

[0005] For the support rod in the above document, the resistance of the support rod body cannot be adjusted. When the support rod is in use, the capacity of the gas-oil mixture inside it may decrease, resulting in certain instability during the support operation of the support rod.

[0006] Therefore, we propose a support robotic arm for an automobile trunk lid to solve the above-mentioned problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a support robotic arm for an automobile trunk lid to solve the problems of being unable to clean the outside of the support rod, dust causing wear on the rod body position of the support rod during use, and being unable to adjust the resistance of the support rod body as mentioned in the above background technique.

[0008] To achieve the above object, the present utility model provides the following technical solution: A support robotic arm for a car trunk lid, including a support rod, an inner rod is nested and connected inside the support rod, and a partition is fixedly connected inside the support rod

[0009] A threaded rod, the threaded rod is nested and connected to the bottom side of the outer end of the support rod, and a handle is fixedly connected to the outer side of the threaded rod, and a threaded sleeve is threadedly connected to the threaded rod.

[0011] Further, the adjusting mechanism includes a limiting plate, the limiting plate is fixedly connected to the outer side of the threaded sleeve, and a fixed rod is fixedly connected above the outer end of the threaded sleeve, and the other end of the fixed rod is fixedly connected to a sealing plug;

[0012] A limiting groove is opened on the inner wall of the support rod, and a limiting rod is fixedly connected inside the limiting groove, and the limiting plate is nested and connected to the outer side of the limiting rod. At the same time, a buffer spring is fixedly connected between one side of the limiting plate and the limiting groove.

[0013] Further, the threaded sleeve and the limiting plate are of an integrated structure, and the limiting plate forms a sliding structure with the limiting rod through the threaded sleeve, and the limiting plate forms an elastic structure with the limiting groove through the buffer spring.

[0014] Further, a communication port is opened inside the sealing plug, and a sleeve rod is nested and connected inside the sealing plug, and a blocking piece is fixedly connected to the outer side of the sleeve rod. At the same time, a return spring is fixedly connected between the blocking piece and the sealing plug.

[0015] Further, the blocking piece and the communication port are both circular in side view, and the diameter of the blocking piece is larger than the diameter of the communication port, and the blocking piece forms an elastic structure with the sealing plug through the return spring.

[0016] Further, the wiping mechanism includes a retractable rod, the retractable rod is fixedly connected inside the movable groove, and a cleaning cotton is fixedly connected to the outer end of the retractable rod.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] 1. When the support device is in use, the inner rod will extend and retract along the support rod. At this time, the cleaning cotton will wipe the outer side of the inner rod synchronously, reducing to a certain extent the possibility of dust accumulating on the outer side of the inner rod and entering the interior of the device, thereby reducing the possibility of wear of the device;

[0022] 4. When the threaded sleeve is moving, it will synchronously drive the limiting plate to move along the limiting rod, and the buffer spring will buffer the limiting plate under the action of its own elastic force, thereby improving the stability of the threaded sleeve during movement;

[0023] 5. When the sealing plug is moving, the gas-oil mixture on the right side of the sealing plug will push the blocking piece under the action of pressure, so that the blocking piece fits with the sealing plug and blocks the communication port. At this time, the gas-oil mixture will not be able to discharge to the left through the communication port, and the sealing plug will hermetically isolate the inside of the support rod, thereby reducing the space of the inner cavity of the support rod and further enhancing the stability of the telescopic operation of the inner rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1:

[0034] As Figure 1 , Figure 4 and Figure 7 shown in the technical solution, the present utility model provides the following technical solution: A support robotic arm for an automobile trunk lid discloses an adjustment mechanism, and the resistance of the device can be adjusted through the adjustment mechanism:

At the same time, an adjustment mechanism for adjusting the resistance of the device is provided between the thread sleeve 12 and the inside of the support rod 1;

[0037] The adjusting mechanism includes a limit plate 8, which is fixedly connected to the outer side of the threaded sleeve 12. A fixing rod 13 is fixedly connected above the outer end of the threaded sleeve 12, and the other end of the fixing rod 13 is fixedly connected to a sealing plug 14. A limit groove 9 is formed on the inner wall of the support rod 1, and a limit rod 10 is fixedly connected inside the limit groove 9. The outer side of the limit rod 10 is nested with the limit plate 8. At the same time, a buffer spring 11 is fixedly connected between one side of the limit plate 8 and the limit groove 9.

[0038] When the damping effect of the device decreases, the user can rotate the handle 6. The handle 6 drives the threaded rod 7 to rotate, thereby synchronously driving the threaded sleeve 12 to move. The threaded sleeve 12 pushes the sealing plug 14 to move inward through the fixing rod 13. At this time, the sealing plug 14 will push the air-oil mixture inside the device to move to the right end of the partition plate 3, so that the air-oil mixture can drive the inner rod 2 to perform telescopic operation well.

[0039] Embodiment 2:

[0040] As Figure 1 、 Figure 2 and Figure 3 shown in the technical solution, the present utility model provides the following technical solution: A support robotic arm for an automobile trunk lid discloses an erasing mechanism, and the outer surface dust of the inner rod 2 can be cleaned through the erasing mechanism:

[0041] A fixed sleeve 4 is fixedly connected to the front side of the outer end of the support rod 1, and an activity groove 19 is formed inside the fixed sleeve 4. An erasing mechanism for cleaning the dust on the outer surface of the inner rod 2 is arranged inside the activity groove 19.

[0042] The erasing mechanism includes a retractable rod 20, which is fixedly connected inside the activity groove 19.

[0048] When the threaded sleeve 12 is moving, it will synchronously drive the limiting plate 8 to move in a limited way along the limiting rod 10. When the limiting plate 8 is moving, it will synchronously squeeze the buffer spring 11. The buffer spring 11 will buffer the limiting plate 8 under the action of its own elastic force, thereby improving the stability when the threaded sleeve 12 moves;

[0049] When the sealing plug 14 is moving, the gas-oil mixture on the right side of the sealing plug 14 will push the blocking piece 15 under the action of pressure. At this time, the blocking piece 15 will move under the limiting action of the sleeve rod 17 until the blocking piece 15 fits with the sealing plug 14 and blocks the communication port 16.
