[0030] As shown in the figure, a guide sleeve structure for installing a straight-tube support rod is used to lift the rear wing of an automobile, comprising: a mounting base 10, the mounting base 10 has mounting columns 11 around it, a positioning through hole 12 and a positioning column 13 are arranged in the middle, and the side of the positioning column 13 has a locking hole 14; a guide shaft 20, the guide shaft 20 has a first shaft portion 21 and a second shaft portion 22 arranged in parallel, the first shaft portion 21 is sleeved on the positioning column 13 and locked by a locking screw, and the second shaft portion 22 is aligned with the positioning through hole 12; a straight-tube support rod 30, ... The rod 30 has a first straight cylindrical portion 31 and a second straight cylindrical portion 32 arranged in parallel, the first straight cylindrical portion 31 is sleeved with the guide shaft 20, and there is a gap between the first straight cylindrical portion 31 and the guide shaft 20; a fixed sleeve 40, the fixed sleeve 40 is installed at the bottom of the first straight cylindrical portion 31, and extends inward to stop the outer wall of the guide shaft 20; a sliding sleeve 50, the sliding sleeve 50 is installed at the top of the guide shaft 20, and extends outward to stop the inner wall of the first straight cylindrical portion 31, wherein the fixed sleeve 40 and the sliding sleeve 50 are both configured as POM or PTFE sleeves.

[0031] In one embodiment of the utility model, the mounting base 10 is a bottom base, and mounting columns 11 are arranged around it to complete the assembly and fixing function. It is specifically equipped to the rear of the vehicle for mounting the rear wing. In addition, the mounting base 10 is also provided with a positioning through hole 12 and a positioning column 13, wherein the positioning through hole 12 is used to install the driving member, and the positioning column 13 is convenient for stabilizing the guide shaft 20, and the two are locked through the locking hole 13.

[0032] The guide shaft 20 is divided into a first shaft portion 21 and a second shaft portion 22, both of which are set as hollow shafts. The straight-tube support rod 30 is divided into a first straight-tube portion 31 and a second straight-tube portion 32, wherein the first straight-tube portion 31 is sleeved with the guide shaft 20, and the two are contoured, while the second straight-tube portion 32 is exposed to the outside and is used to install the support rod, and the other end of the support rod is installed to the rear wing of the car, that is, the function of installing other parts. Among them, the guide shaft 20 and the first straight-tube portion 31 are also matched by a fixed sleeve 40 and a sliding sleeve 50, both of which are self-lubricating materials, such as POM (polyoxymethylene) or PTFE (polytetrafluoroethylene), etc., and the mutual friction coefficient is small. In the process of lifting and lowering the straight-tube support rod 30, it can effectively avoid large-area contact between the inner surfaces of the two, thereby improving the durability of the support rod.

[0033] Specifically, the fixed sleeve 40 is installed at the bottom of the first straight tube portion 31, and the sliding sleeve 50 is installed at the top of the guide shaft 20. The two sleeves are fixed at the top of the guide shaft 20 and the end of the straight tube support rod 30, respectively, which can reduce the guide distance and the sliding stroke.

[0034] A gap is left between the inner surface of the straight-tube support rod 30 and the guide shaft 20, and the thickness of the gap is the thickness of the sliding sleeve 50, which can reduce the cylindricality and straightness requirements of the straight-tube support rod 30 and the guide shaft 20, and reduce the production cost. Moreover, during use, the straight-tube support rod 30 or the guide shaft 20 is slightly deformed, which still does not affect the normal use of the support rod.

[0035] The positioning through hole 12 of the utility model is used to install the driving rod, which is passed through the second shaft portion 22 and fixed to the straight support rod 30, and drives the straight support rod 30 to move up and down. In a preferred embodiment, the driving rod can be set as a screw rod, and one end of the screw rod nut extends from the side of the guide shaft 20 to play a radial limit role, and then the extended part is fixed to the straight support rod 30, so that when the screw rod rotates, the screw rod nut can be axially lifted and lowered to drive the straight support rod 30 to lift the tail wing.

[0036] In one embodiment, a plane bearing 60 is installed in the positioning through hole 12 of the mounting base 10 to reduce the wear of the driving rod.

[0037] Preferably, the upper end of the straight-tube support rod 30 has a sealing cover plate for sealing the first straight-tube portion 31 and the second straight-tube portion 32 to achieve moisture-proof and dust-proof effects.

[0038] In addition, the cross section of the sliding sleeve 50 is in a T-shaped ring shape, and the inner side is clamped on the side wall of the guide shaft 20, so the installation is stable. Furthermore, the upper and lower ends of the sliding sleeve 50 are rounded to facilitate guiding.

[0039] In summary, the utility model is supported by installing the base 10, and the fixed sleeve 40 and the sliding sleeve 50 cooperate to effectively prevent the guide shaft 20 from directly contacting a large area of ​​the inner surface of the straight-tube support rod 30, sliding on the straight-tube support rod 30 and causing wear, thereby improving the durability of the support rod.
