Description

Technical Field

[0001] The utility model relates to the technical field of electric tailgate strut structures, and specifically relates to a strut device for an automobile electric tailgate. Background Technique

[0002] An electric trunk, actually an electric tailgate, means that the trunk is opened and closed electrically, and some cars also have a remote control function. To open the trunk, just press a button in the car, and the trunk will open by itself. If you want to close the trunk, press the close button in the trunk or the close button in the car, and the trunk will close by itself.

[0003] The opening and closing of the tailgate requires the use of an electric tailgate strut to drive the opening and closing of the tailgate. The strut is an essential part of the electric tailgate, and its basic structure consists of two core shaft drive rods. The drive rod is composed of an inner tube and an outer tube through a main shaft driver. The motor and gear in the inner tube drive a lead screw, and the lead screw moves on a nut fixed to the inner side of the outer tube. The drive rod uses the motor located inside it to drive the lead screw to rotate. Under the rotation of the lead screw, a relative displacement occurs in the axial direction of the inner and outer tubes, thereby opening and closing the trunk lid.

[0004] Currently, due to the structure of SUV models, their electric tailgate struts are in the rain gutter in the closed state of the door. Automobiles inevitably need to be used in rainy or humid environments. When the amount of water flowing through the rain gutter is relatively large, the water will enter the inside of the electric tailgate strut through the gaps between the parts of the electric tailgate strut and contact the electronic components, which will cause the function of the electric tailgate strut to fail after long-term use. Therefore, the electric tailgate strut needs to have good waterproof performance.

[0005] In view of this, this technical solution proposes a strut device for an automobile electric tailgate to better solve the above-mentioned problems. Content of the Utility Model

The outer strut and the inner strut form an electric tailgate strut, and the outer strut is sleeved on the inner strut. Connectors for connecting the tailgate and the vehicle body are provided at the tail ends of the outer strut and the inner strut.

[0008] A fixing ring is fixed below the outer support rod, and a first sealing ring is arranged on the fixing ring. A positioning ring is fixed above the inner support rod, and a second sealing ring is arranged on the positioning ring and is attached to the top of the outer support rod. An outer protective tube is fixed on the inner support rod, and the outer protective tube sleeves the outer support rod, the positioning ring and the second sealing ring. The bottom end of the outer protective tube is attached to the first sealing ring.

[0009] In a preferred embodiment, the fixing ring and the first sealing ring have the same outer diameter, and the first sealing ring and the outer protective tube have the same outer diameter.

[0010] In a preferred embodiment, both the second sealing ring and the first sealing ring are composed of a right sealing pad, a left sealing pad and a sealing pad mounting seat.

[0011] In a preferred embodiment, a right sealing pad and a left sealing pad are attached to the positioning ring, and the bottom ends of the right sealing pad and the left sealing pad are both fixed with sealing pad mounting seats and are threadedly connected in the positioning ring.

[0012] In a preferred embodiment, the inner parts of the positioning ring and the fixing ring and the outer part of the sealing pad mounting seat are provided with mutually adapted thread structures.
