Problems solved by technology
The outer casing belongs to the outermost structure, which plays the role of protection and beauty, but it is a moving part. When the coil spring expands and contracts back and forth, direct metal rigid friction will occur between the two sections of the outer casing. Wear and tear, on the other hand, will produce abnormal noise during friction, which will affect the safety performance of the vehicle, and also bring bad experience to users

Embodiment Construction
[0016] Aiming at the above technical problems, the present invention relates to a self-lubricating structure for the electric strut of the tailgate of an automobile, such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 Shown: It has the first outer sleeve 1, the second outer sleeve 2, the lubricating tube 3, the metal inner tube 4, the boss 5 and the groove 6, and the right side of the first outer sleeve 1 is detachably connected to the lubricating tube through threads 3, wherein the metal liner 4 and the bosses 5 arranged in an annular array on the outer surface of the metal liner 4 jointly constitute the lubricating tube 3, the second outer sleeve 2 is sleeved on the lubricating tube 3, and the groove 6 is set on the The inner surface of the second outer sleeve 2 cooperates with the boss 5 arranged on the surface of the metal liner 4. The boss 5 is made of polytetrafluoroethylene. Because the coefficient of friction of polytetrafluoroethylene itself is extre...

The invention relates to a self lubrication structure of an electric brace rod of a car rear door, and belongs to the field of brace rods of car rear doors. The self lubrication structure of the electric brace rod of the car rear door includes a first outer casing pipe and a second outer casing pipe which are connected together. A lubricating pipe is arranged between the first outer casing pipe and the second outer casing pipe. One end of the lubricating pipe is detachably arranged on the first outer casing pipe in a sleeved mode. The lubricating pipe is provided with a metal inner liner pipe,and a convex boss made of polytetrafluoroethylene is arranged on the outer surface of the metal inner liner pipe. The convex boss is attached to the outer surface of the metal inner liner pipe in a circular array mode, and a groove matched with the convex boss on the lubricating pipe is formed in the second outer casing pipe. The self lubrication structure of the electric brace rod of the car rear door has the beneficial effects that the structure is simple, the cost is low, the direct friction between the two outer casing pipes can be effectively avoided, the wear between the two sections ofthe outer casing pipes are effectively reduced, the abnormal noise produced by the outer casing pipes is reduced, the service life of the first outer casing pipe and the second outer casing pipe is improved, the lubricating pipe is detachably connected with the first outer casing pipe, and the later maintenance and repair are convenient.
Description
technical field [0001] The invention relates to a self-lubricating structure of an electric tailgate brace of an automobile, which belongs to the field of tailgate braces of an automobile. Background technique [0002] Automobile tailgate electric strut is mainly composed of motor, screw rod, coil spring, inner casing and outer casing. The outer casing belongs to the outermost structure, which plays the role of protection and beauty, but it is a moving part. When the coil spring expands and contracts back and forth, direct metal rigid friction will occur between the two sections of the outer casing. Wear and tear, on the other hand, will produce abnormal noise during friction, which will affect the safety performance of the vehicle and also bring bad experience to users. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple structure, low cost, which can effectively avoid the direct friction between the two o...
