[0002] In some automobiles, electric tailgates are equipped, which requires the use of struts to support the tailgate. The tailgate strut is one of the accessories of the automobile tailgate. When used in conjunction with the control system, it can realize the automatic opening and closing of the automobile tailgate. The automobile tailgate strut mainly consists of a motor, a lead screw, a spiral spring, an inner sleeve and an outer sleeve.

[0003] However, during the use of the existing automobile electric tailgate strut, rainwater from the outside is likely to enter the inside of the static sleeve through the gap between the static and moving sleeves. After long-term use, when the rainwater enters the strut, it is also likely to cause the driving components installed in the moving sleeve to be damaged by moisture, thereby reducing the use efficiency of the strut. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof structure for the electric part of an automobile electric tailgate strut to solve the above problems. The moving sleeve slides in the static sleeve along with the driving mechanism, so that the sealing ring isolates the rainwater attached to the moving sleeve. The washer can also adsorb water to prevent rainwater from entering the driving mechanism, which is beneficial to improving the waterproof effect inside the strut.

[0005] The utility model realizes the above purpose through the following technical solutions.

By rotating the connecting pipe 201, it can be detached from the static sleeve 1, and thus the static sleeve 1 is in an open state.

[0026] As a technical optimization scheme of the present invention, the sealing ring 207 is located at the end of the moving sleeve 203 close to the static sleeve 1, and the sealing ring 207 is slidably connected to the static sleeve 1. When the sealing ring 207 contacts the inner wall of the static sleeve 1, it can clean the water stains attached to the inner wall of the static sleeve 1.

[0027] As a technical optimization solution of the utility model, the cross-sectional diameter of the gasket 205 is larger than the cross-sectional diameter of the moving sleeve 203, the diameter of the limiting groove 206 is equal to the diameter of the gasket 205, and the gasket 205 is made of a limiting sponge, which facilitates the adsorption of water stains on the moving sleeve 203.

[0028] As a technical optimization solution of the utility model, the movable sleeve 203 is slidingly connected with the connecting pipe 201 and the clamping pipe 202, and the gasket 205 is snap-fitted with the connecting pipe 201. When the gasket 205 is snap-fitted into the inside of the connecting pipe 201, it is convenient for the operator to install the clamping pipe 202 on the connecting pipe 201.

[0029] As a technical optimization solution of the utility model, the driving mechanism 4 includes a driving component 401 and a slide groove 402. The driving component 401 is fixedly installed on the static sleeve 1, and the dynamic sleeve 203 is fixedly connected to the driving component 401. The static sleeve 1 is provided with a slide groove 402. When the dynamic sleeve 203 slides in the static sleeve 1 along the slide groove 402, it can prop open the tailgate.

[0030] As a technical optimization solution of the utility model, a movable sleeve 203 slides in the slide groove 402, and the cross-sectional diameter of the slide groove 402 is equal to the cross-sectional diameter of the sealing ring 207. The sealing ring 207 slides and contacts the inner wall of the static sleeve 1, thereby scraping off the water stains in the static sleeve 1.

[0031] As a technical optimization solution of the utility model, the connecting mechanism 3 includes a connecting rod 302 and a static ball socket 303. The connecting rod 302 is fixedly installed on the static sleeve 1, and the static ball socket 303 is fixedly connected to the connecting rod 302. A fixing frame 304 is installed on the static ball socket 303. The dynamic sleeve 203 is fixedly connected to the dynamic ball socket 301. The static sleeve 1 can be fixed inside the car through the fixing frame 304.

[0032] As a technical optimization solution of the present invention, the diameter of the end of the static ball socket 303 is larger than the diameter of the connecting rod 302, and the diameter of the connecting rod 302 is smaller than the diameter of the static sleeve 1. Through the static ball socket 303, it can be connected to the fixing frame 304, thereby facilitating the installation of the static sleeve 1.

[0033] As a technical optimization solution of the utility model, the moving ball socket 301 is located at the end of the moving sleeve 203 away from the static sleeve 1, and the connecting rod 302 is located at the end of the static sleeve 1 away from the connecting tube 201. When the moving sleeve 203 slides along the static sleeve 1, it can drive the moving ball socket 301 to move.

[0034] When the utility model is in use, firstly, the operator can use a tool to fix the fixing frame 304 inside the car. Since the fixing frame 304 is provided with a static ball socket 303, the static sleeve 1 can be installed inside the car through the connecting rod 302 connected to the static ball socket 303, so as to facilitate the disassembly and assembly of the tailgate support rod; when the tailgate of the car needs to be opened, the control switch of the driving component 401 installed in the static sleeve 1 can be turned on, and the end of the driving component 401 is matched with the moving sleeve 203. When started, the driving component 401 drives the moving sleeve 203 to move along the static sleeve 1. A sealing ring 207 is fixed at the end of the moving sleeve 203. When the sealing ring 207 slides in the slide groove 402 provided in the static sleeve 1, it can contact with the static sleeve 1, so that it can scrape off the water stains attached to the inner wall of the static sleeve 1. When the water stains need to be removed, When cleaning, the connecting tube 201 can be rotated by hand to separate the connecting tube 201 from the static sleeve 1, so that the end of the static sleeve 1 can be in an open state, thereby allowing the water stains to be discharged from the interior of the static sleeve 1; when water stains are attached to the dynamic sleeve 203, the dynamic sleeve 203 slides into the interior of the static sleeve 1, thereby allowing the gasket 205 fixed in the clamping tube 202 to absorb the water stains, thereby helping to prevent the water stains from entering the interior of the strut and affecting the use of the strut; when the gasket 205 on the clamping tube 202 needs to be replaced, the operator can rotate the clamping tube 202 by hand. Since the clamping tube 202 is threadedly connected to the end of the connecting tube 201 away from the static sleeve 1, the clamping tube 202 is rotated to separate it from the connecting tube 201, thereby facilitating its removal from the dynamic sleeve 203, thereby facilitating the replacement or cleaning of the gasket 205.
