Description

Technical Field

[0001] This utility model relates to the field of electric strut technology, specifically an electric strut for a car tailgate. Background Technology

[0002] A power tailgate, also known as a car trunk, is a car door that can be opened and closed electrically. There is a door closing button inside the tailgate. By touching this button, the tailgate can close automatically without manual intervention. Current car tailgates usually use a design with a strut on one side and a pneumatic spring or spring on the other side to ensure the force balance when the tailgate is opened. The strut of the power tailgate opens and retracts along with the tailgate when it is opened and closed.

[0003] In the prior art, such as the announcement number CN218509281U, a strut mechanism for an electric tailgate of a vehicle is proposed. This technical solution relates to a strut mechanism for an electric tailgate of a vehicle, including a strut body. The strut body includes a piston sleeve and a piston rod. The piston rod is sleeved in the piston sleeve and the two are coaxially arranged. The piston sleeve has an opening for the piston rod to pass through. An abutment sleeve extends from the opening and includes a moisture-absorbing block with its outer wall attached to the abutment sleeve. The moisture-absorbing block is annular, and its inner wall abuts against the piston rod. The piston rod and piston sleeve are coaxially fitted. When the tailgate is closed, the piston rod is located in the piston sleeve. When the tailgate is opened, the piston rod extends out of the piston sleeve. The repeated insertion and withdrawal of the piston rod in and out of the piston sleeve can easily bring moisture into the piston sleeve. In this application, an abutting sleeve is provided at the opening, and a moisture-absorbing block is provided at the abutting sleeve. The moisture-absorbing block abuts against the piston rod. As the piston rod moves in and out, the moisture on the piston rod can be wiped clean, preventing water vapor from following the piston rod into the piston sleeve.

[0004] However, existing automotive tailgate electric struts use a sponge block to wipe away moisture or water droplets adhering to the outside of the piston rod, thus preventing water from entering the electric strut. However, the sponge is located inside the sleeve, and it is difficult to expel moisture by relying solely on the evaporation of the sponge itself. As a result, the moisture inside the sponge block increases with the continuous extension and retraction of the piston rod, which means that moisture may still be brought in when the piston rod retracts.

[0005] To address the aforementioned issues, this application proposes an electric tailgate strut. Utility Model Content

[0006] This utility model aims to provide an electric tailgate strut for automobiles, mainly to solve the problem that the internal sponge of the existing electric tailgate strut has difficulty in evaporating moisture, causing the moisture inside the sponge to increase continuously with the extension and retraction of the piston rod, and causing moisture to be brought in even when the piston rod retracts.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An electric tailgate strut for automobiles includes a piston sleeve and a piston rod. A first arc-shaped shell is connected to the upper end of the outer wall of the piston sleeve. A second arc-shaped shell is hinged to one side of the first arc-shaped shell. The first and second arc-shaped shells are sleeved on the upper end of the outer wall of the piston sleeve. A limit component is provided on the outer wall of the second arc-shaped shell. Cleaning cotton is fixedly connected to the inner walls of both the first and second arc-shaped shells. A scraper is fixedly connected to the inner walls of the first and second arc-shaped shells above the cleaning cotton. A drain hole is opened on the first arc-shaped shell. A collection component for collecting wastewater is provided on the outer wall of the first arc-shaped shell.

[0009] The working principle and beneficial effects of this utility model:

[0010] Working principle: When the electric tailgate strut is in use, as the piston rod retracts into the piston sleeve, the water droplets on the outer wall of the piston rod are scraped off by the scraper blades on the inner walls of the first and second arc-shaped shells. Then, a cleaning cotton can be used to clean the water on the outer wall of the piston rod a second time. After the water droplets on the outer wall of the piston rod are scraped off by the scraper blades, they can be drained into the collection assembly through the drain hole. After the limiting assembly is released, the first and second arc-shaped shells can be disassembled, and then the scraper blades and cleaning cotton can be cleaned. After cleaning, the first and second arc-shaped shells are put on the upper end of the outer wall of the piston sleeve and fixed by the limiting assembly. The electric strut can then be used normally.

[0011] Beneficial effects: When using this electric tailgate strut, water droplets on the outer wall of the piston rod can be scraped off with a scraper, and the water on the outer wall of the piston rod can be cleaned a second time with a cleaning cotton, thus ensuring that the outer wall of the piston rod is always clean. After the water droplets on the outer wall of the piston rod are scraped off with the scraper, they can be drained into the collection component through the drain hole. This not only effectively prevents sewage from entering the trunk of the car, but also makes it convenient for people to centrally treat sewage.

[0012] Preferably, a positioning block is fixedly connected to the inner wall of the first arc-shaped shell below the cleaning cotton. A positioning groove matching the positioning block is opened at the upper end of the outer wall of the piston sleeve. When installing the first arc-shaped shell and the second arc-shaped shell, firstly, the first arc-shaped shell is placed on the upper end of the outer wall of the piston sleeve and the positioning block on its inner wall is inserted into the positioning groove. Then, the second arc-shaped shell is rotated so that one end fits against the first arc-shaped shell. The first arc-shaped shell and the second arc-shaped shell can be fixed to the upper end of the outer wall of the piston sleeve by the limiting component, and the electric support rod can be used normally.

[0013] Preferably, the limiting component includes a sliding cavity formed on the outer wall of the second arc-shaped shell. A limiting block is slidably connected inside the sliding cavity. One side of the limiting block extends out of the sliding cavity, and a symmetrical spring is fixedly connected to the other side. The other end of the spring is fixedly connected to the inner wall of the sliding cavity. A connecting block is fixedly connected to one side of the first arc-shaped shell. A square groove matching the limiting block is formed on the connecting block. After the first arc-shaped shell is fitted onto the upper end of the outer wall of the piston sleeve, the limiting block is pressed to enter the sliding cavity. Then, the second arc-shaped shell is rotated so that one end fits against the first arc-shaped shell. Then, the limiting block is released. The limiting block will pop out under the action of the spring inside the sliding cavity and engage with the square groove on the connecting block. This fixes the first arc-shaped shell and the second arc-shaped shell on the upper end of the outer wall of the piston sleeve. After pressing the limiting block to disengage it from the square groove, the first arc-shaped shell and the second arc-shaped shell can be disassembled, making it convenient for people to clean the scraper and cleaning cotton.

[0014] Preferably, sliders are fixedly connected to both sides of the limiting block, and the inner wall of the sliding cavity is provided with a sliding groove that matches the slider. When the limiting block slides inside the sliding cavity, the sliders on both sides of the limiting block and the sliding groove on the inner wall of the sliding cavity can play a good limiting and guiding role for the limiting block. This not only makes the limiting block more stable when sliding inside the sliding cavity, but also effectively prevents the limiting block from leaving the inside of the sliding cavity.

[0015] Preferably, one corner of the limiting block extending out of the sliding cavity is set as an inclined surface. By setting one side of the limiting block as an inclined surface, after the first arc-shaped shell is fitted onto the upper end of the outer wall of the piston sleeve, when the second arc-shaped shell is rotated, the connecting block on the first arc-shaped shell will squeeze the inclined surface of the limiting block, causing it to slide automatically into the sliding cavity. When one end of the second arc-shaped shell is in contact with the first arc-shaped shell, the limiting block will pop out under the action of the spring inside the sliding cavity and engage with the square groove on the connecting block, thus fixing the first arc-shaped shell and the second arc-shaped shell to the upper end of the outer wall of the piston sleeve. This makes the installation of the first arc-shaped shell and the second arc-shaped shell more convenient.

[0016] Preferably, the collection assembly includes a collection box detachably connected to the outer wall of the first arc-shaped shell. A water inlet hole matching the drain hole is opened on one side of the collection box, and a water outlet is opened on the top of the collection box. A rubber plug matching the water outlet is fixedly connected to the top of the collection box on the side of the water outlet. During the operation of the electric strut of the car tailgate, water droplets on the outer wall of the piston rod are scraped off by the scraper and discharged into the collection box through the drain hole and the water inlet hole. After the collection box is removed, the rubber plug is pulled to open the water outlet, and then the sewage inside the collection box can be discharged through the water outlet. This not only effectively prevents sewage from entering the trunk of the car, but also makes it convenient for people to centrally treat sewage.

[0017] Preferably, a symmetrical T-shaped block is fixedly connected to one side of the collection box, and a T-shaped groove matching the T-shaped block is opened on the outer wall of the first arc-shaped shell. After inserting the T-shaped block on one side of the collection box into the T-shaped groove on the first arc-shaped shell, the collection box can be installed. The collection box can be disassembled by pulling it upward. This makes the disassembly and assembly of the collection box more convenient, thus making it easier for people to clean the sewage inside the collection box. Attached Figure Description
