Description

Technical Field

[0001] This utility model relates to the technical field of tipper cylinders for automobile tailgate cylinders, and more particularly to a tipper cylinder for automobile tailgate cylinders. Background Technology

[0002] The tailgate cylinder is the core actuator of the hydraulic tailgate system, responsible for driving the tailgate's lifting, tilting, and other actions. Its performance directly affects the tailgate's working efficiency, stability, and service life.

[0003] Existing automotive tailgate cylinders control the opening and closing of the tailgate. These cylinders typically have vents, usually located on the cylinder barrel or cylinder head, to expel air from the cylinder and ensure the stability of the hydraulic system. However, the location of the vent can also affect the tailgate cylinder. If contaminants clog the vent, the cylinder's venting function may be lost. If rainwater is drawn into the vent, the cylinder interior will rust, causing malfunctions. Furthermore, contaminants entering the cylinder can accelerate cylinder body damage. Therefore, existing automotive tailgate cylinders are inconvenient to use. To address this, we provide a tailgate cylinder with a flap mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the exhaust port on the tailgate cylinder of an automobile can cause cylinder malfunction or damage, and to provide a flap cylinder for the tailgate cylinder of an automobile.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flip-up cylinder for a car tailgate hydraulic cylinder, comprising: a hydraulic cylinder mechanism, the hydraulic cylinder mechanism including a cylinder head, a cylinder sleeve on the outer surface of the cylinder head, the cylinder sleeve being threadedly connected to the cylinder head, a cylinder bottom being sleeved inside one end of the cylinder sleeve, the cylinder bottom being fixedly connected to the cylinder sleeve, a piston rod being sleeved inside the cylinder head and the cylinder sleeve, a piston body being sleeved on the outer surface of the piston rod, the piston body being fixedly connected to the piston rod, a combined oil seal being sleeved on the outer surface of the piston body, the combined oil seal being fixedly connected to the piston body, a flat-head compression spring being sleeved on the outer surface of the piston rod, the piston rod being slidably connected to the flat-head compression spring, and a connecting mechanism being provided on the outer side of the hydraulic cylinder mechanism.

[0006] In a preferred embodiment, an O-ring is provided in the mounting groove on the cylinder head, and a dust seal is fitted inside the cylinder head, with the dust seal being fixedly connected to the cylinder head.

[0007] In a preferred embodiment, a POM support ring is fitted inside the cylinder head, the POM support ring is fixedly connected to the cylinder head, and a dust seal is fitted inside the cylinder head.

[0008] In a preferred embodiment, the dust seal is fixedly connected to the cylinder head, and an oil nozzle is welded to the outside of the cylinder barrel, with the oil nozzle fixedly connected to the cylinder barrel.

[0009] In a preferred embodiment, the connecting mechanism includes an earring, which is fitted onto the outer surface of the cylinder bottom and is threadedly connected to the cylinder bottom.

[0010] In a preferred embodiment, a second lug is fitted onto the outer surface of the piston rod, and an adjusting nut is fitted onto the outer surface of the piston rod.

[0011] In a preferred embodiment, the adjusting nut is threadedly connected to the piston rod, and the adjusting nut is fixedly connected to the second earring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, by setting up a hydraulic cylinder mechanism, ensures that the car tailgate hydraulic cylinder is not affected by air entering it during use. By eliminating the vent hole, contaminants can clog it, preventing the cylinder from losing its venting function. It also prevents rainwater from being sucked into the vent hole, thus preventing rust and cylinder malfunction. Furthermore, contaminants entering the cylinder could accelerate cylinder body damage. Therefore, this invention improves the ease of use of the car tailgate hydraulic cylinder and reduces its failure rate. Hydraulic oil enters through the nozzle and pushes the piston forward. An extended flat-head compression spring and cylinder are incorporated; the flat-head compression spring is located inside the cylinder, thus flattening the piston... The compression spring can be driven to compress, so that a certain space can always be maintained inside the cylinder to store compressed gas. Moreover, the pressure formed by the compressed air entering the cylinder will not have a negative impact on the piston body and the combined oil seal. This allows the car tailgate cylinder to adjust the car tailgate more efficiently. The combined oil seal is set up, and when used with the piston body, it can make close contact with the inner wall of the cylinder, thereby blocking the hydraulic oil entering the cylinder. This allows the piston rod to be pushed and moved by the hydraulic oil. The connecting mechanism is set up so that the car tailgate cylinder can be connected to the car body components and the tailgate, thereby playing the role of adjusting the raising, lowering and opening of the tailgate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a flip-up hydraulic cylinder for a car tailgate, comprising: a hydraulic cylinder mechanism 1, the hydraulic cylinder mechanism 1 including a cylinder head 11, a cylinder barrel 12 sleeved on the outer surface of the cylinder head 11, the cylinder barrel 12 being threadedly connected to the cylinder head 11, a cylinder bottom 13 sleeved inside one end of the cylinder barrel 12, the cylinder bottom 13 being fixedly connected to the cylinder barrel 12, a piston rod 14 sleeved inside the cylinder head 11 and the cylinder barrel 12, a piston body 15 sleeved on the outer surface of the piston rod 14, the piston body 15 being fixedly connected to the piston rod 14, and a combined oil seal 16 sleeved on the outer surface of the piston body 15, the combined oil seal 16 being fixedly connected to the piston body 15. A flat-headed compression spring 17 is sleeved on the outer surface of the piston rod 14, and the piston rod 14 is slidably connected to the flat-headed compression spring 17. A connecting mechanism 2 is provided on the outer side of the cylinder mechanism 1. An O-ring seal 18 is provided in the mounting groove on the cylinder head 11. A dust seal 19 is sleeved inside the cylinder head 11 and is fixedly connected to the cylinder head 11. A POM support ring 101 is sleeved inside the cylinder head 11 and is fixedly connected to the cylinder head 11. A second dust seal 102 is sleeved inside the cylinder head 11 and is fixedly connected to the cylinder head 11. An oil nozzle 103 is sleeved inside the cylinder barrel 12 and is fixedly connected to the cylinder barrel 12.

[0020] In this embodiment, by setting a piston rod 14 and a piston body 15, which can slide inside the cylinder 12, the piston rod 14 and piston body 15 can push the second lug 22, causing the second lug 22 to drive and adjust the tail plate. A combined oil seal 16 is provided, which can make tight contact with the inner wall of the cylinder 12. Under the action of the combined oil seal 16, the piston body 15 can block the hydraulic oil entering the cylinder 12, allowing the pressurized hydraulic oil to squeeze and push the piston rod 14 and piston body 15. Furthermore, an O-ring seal 18 is provided, and after being squeezed and deformed, the O-ring seal 18 can seal the cylinder head 11 and the cylinder 12. The gaps between the cylinder barrel 12 and the cylinder head 11 are filled, thus maintaining a sealed connection. A flat-head compression spring 17 is provided, which controls the space of the cylinder barrel 12. Even if the flat-head compression spring 17 is fully compressed, the internal space of the cylinder barrel 12 remains suitable, so that the compressed air entering the cylinder barrel 12 will not have a negative impact and will not affect the normal use of the hydraulic cylinder. Dust seal 19 and dust seal 2 102 are provided to prevent dust adhering to the outer surface of the piston rod 14 from entering the interior of the cylinder barrel 12. At the same time, a POM support ring 101 is provided, which supports the inner side of the cylinder head 11, making the cylinder head 11 more durable.

[0021] Example 2 like Figures 1-4 As shown, the connecting mechanism 2 includes an earring 21, which is sleeved on the outer surface of the cylinder bottom 13 and threadedly connected to the cylinder bottom 13. An earring 22 is sleeved on the outer surface of the piston rod 14, and an adjusting nut 23 is sleeved on the outer surface of the piston rod 14. The adjusting nut 23 is threadedly connected to the piston rod 14 and fixedly connected to the earring 22.

[0022] In this embodiment, by setting a connecting mechanism 2, the hydraulic cylinder mechanism 1 can be connected to the tailgate and the car body. A first earring 21 is set, and a connecting hole is opened on the first earring 21. Then, a specific fastener can be used to connect the first earring 21 to the car body. A second earring 22 is set, and the second earring 22 can be connected to the tailgate of the car through a fastener. In addition, an adjusting nut 23 is set, and the adjusting nut 23 can be threadedly connected to the piston rod 14, so that the position of the second earring 22 can be adjusted so that it can be smoothly connected to the tailgate of the car.

[0023] Working principle: like Figures 1-4As shown, in use, the first earring 21 and the second earring 22 can be connected to the car body and tailgate using special fasteners. If the position of the second earring 22 is not suitable, the adjusting nut 23 can be used to connect to the piston rod 14 to make the position of the second earring 22 more suitable. At this time, the oil nozzle 103 is connected to the oil pipe of the hydraulic control system. Therefore, when the hydraulic system transmits hydraulic oil into the cylinder 12 through the oil pipe and the oil nozzle 103, it will squeeze the piston body 15, allowing the piston body 15 to slide inside the cylinder 12. The piston body 15, with the cooperation of the combined oil seal 16, can block the hydraulic oil. Meanwhile, the piston body 15 drives the piston rod 14 to move, causing the piston rod 14 to slide continuously from inside the cylinder 12. The piston rod 14 can then control the tail plate using the second lug 22. When the piston rod 14 slides, the piston body 15 and cylinder head 11 compress the flat-head compression spring 17 and leave enough space to store compressed gas, so that the air inside the cylinder 12 will not have a negative impact. When the piston rod 14 enters the cylinder 12, the dust on the outer surface will be blocked by the first dust seal 19 and the second dust seal 102, preventing it from entering the inside of the cylinder 12. Thus, the inside of the cylinder 12 can be kept clean and will not be damaged by foreign objects.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
