[0002] A sunroof guide rail is a track device used to guide and support the movement of sunroof glass or sunroof visor. It is usually installed on the internal structural frame of the car roof to provide a precise guide path for the opening and closing of the sunroof, ensuring that the sunroof can slide smoothly along the predetermined track.
[0003] Currently, sunroofs are increasingly widely used in various types of vehicles. The guide rail, as a key component supporting and guiding the sunroof's movement, plays a crucial role in the smooth operation and overall performance of the sunroof. However, existing sunroof guide rails have some shortcomings. For example, when sunroof guide rails are exposed to the outside for extended periods, impurities can accumulate inside, leading to increased friction between the sunroof sliding components and the guide rail. Forcibly opening the sunroof can easily damage the sliding components, thus affecting the normal use of the sunroof. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to address the above-mentioned problems by providing a lightweight automotive sunroof guide rail, which has the advantage of reducing the friction between the automotive sunroof guide rail and the sliding components.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6 As shown, this utility model provides a lightweight car sunroof guide rail, including a car sunroof guide rail body 1. A cavity 2 is opened at the bottom of the inner cavity of the car sunroof guide rail body 1. A ball 3 is movably installed inside the cavity 2. A fixing rod 4 is fixedly connected inside the car sunroof guide rail body 1. A wheel 5 is movably sleeved on the outer surface of the fixing rod 4. The outer surface of the wheel 5 is movably connected to the inner surface of the car sunroof guide rail body 1.
[0024] When the sunroof sliding assembly slides inside the sunroof guide rail body 1, the outer side and bottom of the sunroof sliding assembly are in contact with the outer surfaces of the wheel 5 and the ball 3, respectively. With the cooperation of the wheel 5 and the ball 3, the friction between the sunroof sliding assembly and the sunroof guide rail body 1 is reduced, making the movement of the sunroof sliding assembly inside the sunroof guide rail body 1 smoother.
[0025] The top of the car sunroof guide rail body 1 is provided with a mounting hole 6, and the mounting hole 6 is circular in shape.
[0026] The design of mounting hole 6 makes it easy for installers to use bolts to connect to the top of the car using mounting holes 6, thereby achieving the purpose of quickly installing the car sunroof guide rail body 1.
[0027] The car sunroof guide rail body 1 has an inclined groove 7 located on the right side of the cavity 2 inside, and the inside of the inclined groove 7 is connected to the inside of the cavity 2.
[0028] This design allows operators to add lubricant into the cavity 2 through the inclined groove 7, thereby reducing the friction between the sunroof sliding assembly and the ball 3.
[0029] Among them, a fixing block 8 is fixedly connected to the bottom of the outer side of the car sunroof guide rail body 1, and a threaded rod 9 is threadedly connected inside the fixing block 8.
[0030] The design of the fixing block 8 serves to support the threaded rod 9, ensuring that the threaded rod 9 can rotate stably inside the fixing block 8.
[0031] The top of the threaded rod 9 is movably sleeved with a lifting plate 10, the bottom of the lifting plate 10 is movably connected to the top of the fixed block 8, and the outer surface of the lifting plate 10 is movably connected to the outer side of the car sunroof guide rail body 1.
[0032] Due to this design, when the rotating threaded rod 9 moves upward, it will drive the lifting plate 10 to move upward.
[0033] The lifting plate 10 has connecting rods 11 hinged to both the left and right sides of its top. The other end of the connecting rod 11 is hinged to a connecting block 12. The outer surface of the connecting block 12 is movably connected to the inner wall of the car sunroof guide rail body 1. The other end of the connecting block 12 is fixedly connected to a baffle 13. There are two baffles 13, and the outer surfaces of the two baffles 13 are movably connected to the inner wall of the car sunroof guide rail body 1.
[0034] The rotation of the two connecting rods 11 will cause the two connecting blocks 12 to move towards each other, which in turn causes the two baffles 13 to move towards each other to seal the inclined groove 7, preventing external dust from entering the interior of the inclined groove 7 and causing blockage.
[0035] There are thirteen round beads 3, all of which are the same size and have smooth outer surfaces.
[0036] The design of thirteen round beads 3 makes the movement of the car sunroof sliding component within the car sunroof guide rail body 1 smoother.
[0037] Working principle and usage process of this utility model:
[0038] When the sunroof sliding assembly moves inside the sunroof guide rail body 1, its outer side and bottom contact the outer surfaces of the wheel 5 and ball 3, respectively. Due to the design of the wheel 5 and ball 3, the friction between the sunroof sliding assembly and the sunroof guide rail body 1 is reduced, making the movement of the sunroof sliding assembly inside the sunroof guide rail body 1 smoother and preventing damage caused by excessive friction between the sunroof sliding assembly and the sunroof guide rail body 1.
[0039] When the lubricant inside cavity 2 runs out, it needs to be added. At this time, rotating the threaded rod 9 upward will drive the lifting plate 10 upward, which in turn causes the two connecting rods 11 to rotate, causing the two connecting blocks 12 to move in opposite directions. This causes the two baffles 13 to move in opposite directions, releasing the sealing effect on the inclined groove 7. At this time, the operator can add lubricant into the cavity 2 through the inclined groove 7. After the lubricant is added, rotating the threaded rod 9 downward again will drive the two baffles 13 to reset and seal the inclined groove 7, preventing external dust from entering the inclined groove 7 and causing blockage.
