This product is an automotive accessory, especially related to an improved structure of the linear actuator of the automobile tailgate.


The car tailgate linear actuator is used to open and close the car's tailgate. When the tailgate of the automobile is opened and closed, the outer and inner tubes made of a metal material as well as the inner tube and the spring not only rub against each other. Noise is generated, and the inner and outer tubes are damaged prematurely, thereby scrapping the entire electric push rod.

Technical realization elements:


In order to solve the problems in the above technique, the linear actuator provides a linear actuator with no direct contact between the outer tube and the inner tube.


The linear actuator includes an outer tube, an inner tube movably nested in the outer tube, a spring that is compressibly sleeved in the inner tube, and an outer tube rubber sleeve disposed at the left end of the outer tube. The left end of the outer tube is provided with an outer tube socket, and the inner and outer diameters of the outer tube socket are larger than the inner and outer diameters of the outer tube. The outer end of the outer tube rubber sleeve is provided with an outer tube. It is a rubber sleeve interface, and the outer tube sleeve interface is sleeved with the outer tube sleeve. The inner diameter of the inner tube sleeve is smaller than the inner diameter of the outer tube. The first waterproof ring of the outer tube is the second end of the inner rubber tube is a second waterproof ring. The inside of the left end of the rubber tube, the second waterproof ring is located at the right end of the outer rubber sleeve. An inner tube socket is provided, and an outer diameter of the inner tube and the inner tube socket is larger than an inner diameter and an outer diameter of the inner tube. The inner tube rubber sleeve is provided with an inner tube rubber sleeve interface, the inner tube rubber sleeve interface and the inner tube sleeve interface are sleeved together, the outer tube rubber sleeve has an outer diameter larger than the outer tube outer diameter, and the inner tube rubber sleeve has a right port at the middle inner tube The right end is inserted into the outer tube from the left side and can be moved back and forth in the outer tube. During the entire movement, the inner tube and the outer tube are not in direct contact under the support of the outer tube rubber sleeve and the inner tube rubber sleeve.


The beneficial effect is that the direct friction between the inner and outer tubes of the metal is converted into direct friction between the rubber sleeve and the inner and outer tubes, thereby effectively reducing the friction noise and reducing the compression and release of the spring, and the slit is advantageous for the spring. Sliding also reduces frictional noise between the spring and the inner tube.
