[0072] Please refer to the attached Figures 1 to 9 In the embodiment of the present application, lubricating oil is provided between the first roller 23 or the second roller 33 and the limiting arm 2311. This lubricating oil is located within the active gap 2311b and can lubricate the opposing side walls between the limiting arm 2311 and the first roller 23 or the second roller 33, allowing the lubricating oil to fill the active gap 2311b. The lubricating oil reduces the friction coefficient between the limiting arm 2311 and the first roller 23 or the second roller 33, thereby reducing the rotational resistance of the first roller 23 or the second roller 33 on the limiting arm 2311, thereby improving the smoothness of the rotation of the first roller 23 or the second roller 33. At the same time, the heat generated by friction between the limiting arm 2311 and the first roller 23 or the second roller 33 is reduced. Optionally, the active gap 2311b is 0.05 to 0.1 mm, ensuring sufficient space for the lubricating oil to fill.

[0073] The metal ring 231 includes a ring body 2312, which is arranged in a ring shape so that the first roller 23 or the second roller 33 can rotate relative to the metal ring 231 through the ring body 2312. The limiting arm 2311 is annularly connected to the ring body 2312 and extends outward; the limiting arm 2311 does not exceed the position of the first roller 23 or the second roller 33 relative to the roller groove 23a, ensuring that the limiting arm 2311 limits the upper side of the first roller 23 or the second roller 33.

[0074] The ring body 2312 and the limiting arm 2311 are an integrated connection structure, which improves the connection strength between the ring body 2312 and the limiting arm 2311 and ensures the connection stability between the ring body 2312 and the limiting arm 2311; the ring body 2312 is detachably connected to the beam body 10 so that the ring body 2312 can be connected to or detached from the beam body 10, thereby improving the loading and unloading convenience of the first roller 23 or the second roller 33.

[0075] The ring body 2312 has a through hole 2312a for inserting a screw. The through hole 2312a is screwed to the beam body 10 and presses against the ring body 2312. The ring body 2312 is stationary relative to the beam body 10. The first roller 23 or the second roller 33 rotates relative to the ring body 2312 to facilitate the removable connection of the ring body 2312 to the beam body 10 via the screw. Optionally, the beam body 10 is a plastic beam body, and the screw is a self-tapping screw.

[0076] The roller groove 23a is surrounded by the circumferential side wall of the first roller 23 or the second roller 33, and the roller groove 23a is provided with a groove bottom 23b. The first steel wire 22 or the second steel wire 32 is pressed against the groove bottom 23b, and the groove bottom 23b is an arc side wall, so that the roller groove 23a can support the first steel wire 22 or the second steel wire 32 through the groove bottom 23b.

[0077] The roller groove 23a is provided with groove side portions 23c, which are arranged on both sides of the groove bottom 23b and transitionally connected to the groove bottom 23b. The groove side portions 23c are inclined sidewalls and extend toward the groove bottom 23b to guide the first steel wire 22 or the second steel wire 32, preventing the first steel wire 22 or the second steel wire 32 from escaping the roller groove 23a, thereby ensuring the arrangement of the first steel wire 22 or the second steel wire 32 relative to the roller groove 23a. Furthermore, the transition connection ensures smooth contact between the surface of the first steel wire 22 or the second steel wire 32 and the groove side portions 23c and the groove bottom 23b, reducing friction between the first steel wire 22 or the second steel wire 32 and the roller groove 23a.

[0078] Please refer to the attached Figures 1 to 9In the embodiment of the present application, the sunroof glass drive module 20 further includes a guide rail 26, a guide 27, and an elastic member 28. The beam body 10 is provided with a beam body limiter 13. The guide rail 26 is mounted on the beam body 10 and avoids the beam body limiter 13, so that the guide rail 26 is fixed to the beam body 10. The guide 27 is provided on one side of the beam body limiter 13. The guide 27 can move relative to the guide rail 26 and move closer to or away from the beam body limiter 13, so that the position of the guide 27 relative to the guide rail 26 can be adjusted. The elastic member 28 is provided between the guide 27 and the beam body limiter 13 and applies an elastic force to the guide 27, so that the guide 27 can move elastically relative to the beam body limiter 13.

[0079] The first steel wire 22 passes through the guide 27 and is connected to the guide 27; the guide 27 reciprocates along the guide rail 26 as the first steel wire 22 moves, and adjusts the compression state or release state of the elastic member 28 to adjust the tension of the first steel wire 22; the steel wire is used to drive the sunroof glass 25 to open or close, so that the guide 27 can guide the movement trajectory of the first steel wire 22, thereby facilitating the restriction of multiple movement directions of the first steel wire 22, effectively preventing the first steel wire 22 from moving, and improving the smoothness of movement of the sunroof glass 25.

[0080] Please refer to the attached Figures 1 to 8 In the embodiment of the present application, the guide 27 is provided with a central through hole 27a, and the first steel wire 22 can pass through the central through hole 27a; so that the first steel wire 22 can pass through the space of the central through hole 27a to pass through the guide 27, thereby facilitating the guide 27 to restrict the first steel wire 22 and prevent the first steel wire 22 from moving. At the same time, the guide 27 guides the movement direction of the first steel wire 22.

[0081] The guide 27 is provided with a first connecting portion 271 and a second connecting portion 272; the first connecting portion 271 and the second connecting portion 272 are distributed at different positions of the guide 27; the first connecting portion 271 is connected to the first steel wire 22; the second connecting portion 272 is connected to the elastic member 28, so that the guide 27 can connect the first steel wire 22 and the elastic member 28 through the first connecting portion 271 and the second connecting portion 272, thereby facilitating the first steel wire 22 to drive the guide 27 to reciprocate relative to the guide rail 26.

[0082] One end of the elastic member 28 is connected to the second connecting portion 272 ; the other end of the elastic member 28 is connected to the beam limiting portion 13 and is positioned and connected with the beam limiting portion 13 , ensuring the position accuracy of the elastic member 28 relative to the beam limiting portion 13 .

[0083] The beam body limiting portion 13 is provided with an outwardly protruding positioning arm 131, and the elastic member 28 is sleeved on the positioning arm 131 and is positioned by the positioning arm 131, so that the beam body limiting portion 13 can limit the elastic member 28 through the positioning arm 131, thereby ensuring the position accuracy of the elastic member 28 relative to the beam body limiting portion 13.

[0084] The elastic member 28 is a spring; the first steel wire 22 passes through the beam limit portion 13, the positioning arm 131, the elastic member 28 and the guide 27, so that the first steel wire 22 extends through the beam limit portion 13 to the skylight glass 25, thereby facilitating the connection between the first steel wire 22 and the skylight glass 25.

[0085] The first connecting portion 271 is a connecting arm 2711 disposed on the inner sidewall of the central through hole 27a. This connecting arm 2711 is engaged with the first steel wire 22 and is arranged stationary relative to the first steel wire 22, ensuring a stable connection between the first connecting portion 271 and the first steel wire 22. During movement, the first steel wire 22 is subjected to tension from the guide 27 and the elastic member 28, allowing the elastic member 28 to tighten and loosen during operation. This reduces the risk of movement of the first steel wire 22 due to vibration or movement within the sunroof glass 25, ensuring efficient movement of the entire sunroof glass 25.

[0086] The guide 27 is provided with a receiving cavity 27b, which is used to receive one end of the elastic member 28; the second connecting portion 272 is provided on the inner side wall of the receiving cavity 27b so that one end of the elastic member 28 can be connected to the inner side of the guide 27 through the receiving cavity 27b.

[0087] When the sunroof glass 25 begins to open, the first steel wire 22 pulls the guide 27 toward the beam stop 13. The elastic member 28 is gradually compressed, and the guide 27, as the spring compresses, exerts a tightening force on the first steel wire 22, limiting movement of the first steel wire 22 due to vibration or movement. When the sunroof glass 25 begins to close, the first steel wire 22 pulls the guide 27 away from the beam stop 13. The elastic member 28 gradually releases, and the guide 27 gradually moves away from the beam stop 13 as the spring releases. This effectively prevents movement of the first steel wire 22 and improves the smooth movement of the sunroof glass 25.

[0088] Action process: the first motor 212 drives the first winding wheel 214 to rotate clockwise, the first winding wheel 214 drives the first steel wire 22, and the multiple first rollers 23 pull the first steel wire 22. The first steel wire 22 drives the sunroof glass 25 to open the sunroof glass 25. Conversely, the first motor 212 drives the first winding wheel 214 to rotate counterclockwise to close the sunroof glass 25.

[0089] The second motor 312 drives the second winding wheel 314 to rotate clockwise, and the second winding wheel 314 drives the second steel wire 32. Multiple second rollers 33 pull the second steel wire 32. The second steel wire 32 drives the sunshade curtain 35 to open the sunshade curtain 35 and wind the roller 36. Conversely, the second motor 312 drives the second winding wheel 314 to rotate counterclockwise to close the sunshade curtain 35.
