[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-Figure 4The utility model provides the following technical solutions: a self-lubricating automobile sunroof track, comprising a window frame 1 and a track body 11 fixed on the window frame 1, the window frame 1 also having a storage groove 12 for embedding the sunroof, and also comprising a self-lubricating mechanism 2, and the self-lubricating mechanism 2 includes: a box body 21, a liquid storage balloon 23, a liquid outlet 231, a push plate 25, a driving rod 26 and a reset spring 27.

[0037] Further, by Figure 1-Figure 3 As shown, in this embodiment, the box body 21 is fixed on the track body 11, the liquid storage balloon 23 is located in the box body 21, the liquid outlet 231 is fixed to the bottom end of the liquid storage balloon 23, and a through hole 111 is provided on the track body 11. The liquid outlet 231 penetrates the box body 21 and then is embedded in the through hole 111. The push plate 25 is located in the box body 21, and the driving rod 26 is fixed on the push plate 25, and the end of the driving rod 26 away from the push plate 25 penetrates the box body 21. The protruding end of the push plate 25 is a triangular structure, and one end of the return spring 27 is fixedly connected to the inner wall of the box body 21, and the other end is fixedly connected to the push plate 25. After adopting the above scheme, when in use, the window frame 1 is fixed to the top of the car, the sunroof is set on the inner side of the window frame 1, and the slider is used to connect with the track body. 11 sliding fit, first store a proper amount of lubricating oil in the liquid storage balloon 23, during the process of opening and closing the sunroof, because the sunroof will move a certain distance in the vertical direction, for example, when opening the sunroof, the sunroof will first move up to leave the storage slot 12, and then move toward the rear of the vehicle. When the sunroof moves in the vertical direction, it will squeeze the inclined surface of the protruding end of the driving rod 26, and the inclined surface will generate a component force to move the driving rod 26. The driving rod 26 pushes the push plate 25 to squeeze the liquid storage balloon 23. At this time, the return spring 27 is stretched, and the lubricating oil in the liquid storage balloon 23 is squeezed out from the liquid outlet 231 into the track body 11, so as to lubricate the track body 11, reduce the sliding friction, avoid the problem of mechanical jamming, and make the opening and closing of the sunroof smoother.

[0038] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, four return springs 27 are diagonally distributed, and the return springs 27 are evenly stressed, which also ensures the stability of the push plate 25.

[0039] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a liquid injection port 232, which is fixed on the liquid storage balloon 23 and penetrates the box body 21. The liquid injection port 232 is provided to facilitate the injection of lubricating oil into the liquid storage balloon 23.

[0040] Preferably, by Figure 1-Figure 3As shown, in this embodiment, it also includes: a sealing screw cap 24, which is installed on the filling port 232 by threaded engagement. When the lubricating oil in the liquid storage balloon 23 is sufficient, the sealing screw cap 24 is installed on the filling port 232 to prevent external dust from entering the liquid storage balloon 23 and to prevent the lubricating oil from being squeezed out of the filling port 232 during use.

[0041] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, the outer wall of the push plate 25 abuts against the inner wall of the box body 21 to improve the stability of the push plate 25.

[0042] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a top plate 22, the top end of the box body 21 is open, the top plate 22 is fixed to the top end of the box body 21 by bolts, and the set top plate 22 is used to restrict the liquid storage balloon 23 from the top to ensure the stability of the liquid storage balloon 23 and prevent external dust from entering the box body 21. The top plate 22 is fixed by bolts, which is convenient and stable to install, and also easy to disassemble.

[0043] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a C-type rubber pad 3, which is bonded and fixed to the sunroof slider, and the outer wall of the C-type rubber pad 3 is against the inner wall of the track body 11. During opening and closing of the sunroof, the sunroof slider drives the C-type rubber pad 3 to move in the track body 11, and a small amount of lubricating oil is adhered to the outer wall of the C-type rubber pad 3, which can only ensure the lubrication effect and can also effectively avoid excessive discharge of the lubricating oil.

[0044] Preferably, by Figure 1-Figure 4 As shown, in the present embodiment, guide grooves 31 are evenly provided on the C-type rubber liner 3. Therefore, when in use, the lubricating oil liquid will enter the guide groove 31 after being squeezed out from the liquid outlet 231. A small amount of lubricating oil liquid can be stored in the guide groove 31. During the opening and closing of the sunroof, the sunroof slider drives the C-type rubber liner 3 to move in the track body 11 to lubricate the track body 11. The C-type rubber liner 3 and the guide groove 31 can also prevent the lubricating oil liquid from dripping into the vehicle.

[0045] Components not described in detail herein are prior art.

[0046] Working principle and use process of the utility model: When the track body 11 of the utility model is in use, the window frame 1 is fixed to the top of the car, the skylight is arranged inside the window frame 1, and the slider is used to slide with the track body 11;

[0047] First, a proper amount of lubricating oil is stored in the liquid storage balloon 23. During the opening and closing process of the sunroof, the sunroof will move a certain distance in the vertical direction. When the sunroof moves in the vertical direction, the inclined surface of the extended end of the driving rod 26 will be squeezed. The inclined surface is subjected to force to generate a component force, so that the driving rod 26 moves. The driving rod 26 pushes the push plate 25 to squeeze the liquid storage balloon 23. At this time, the return spring 27 is stretched, and the lubricating oil in the liquid storage balloon 23 is squeezed out from the liquid outlet 231 into the track body 11 to lubricate the track body 11, thereby reducing the sliding friction, avoiding the problem of mechanical jamming, and making the sunroof open and close more smoothly.

[0048] After being squeezed out from the liquid outlet 231, the lubricating oil liquid will enter the guide groove 31. A small amount of lubricating oil liquid can be stored in the guide groove 31. During the opening and closing of the sunroof, the sunroof slider drives the C-type rubber pad 3 to move in the track body 11 to lubricate the track body 11. The C-type rubber pad 3 and the guide groove 31 can also prevent the lubricating oil liquid from dripping into the car.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
