Roller assembly and automotive sunroof device

Abstract

This application provides a roller assembly and an automotive sunroof device. The roller assembly includes a beam, a metal ring, and a roller. The beam has a supporting arm. The metal ring is disposed on one side of the beam and fixedly connected to the beam. The metal ring has a limiting arm, forming a limiting space between the limiting arm and the supporting arm. The roller is located within this limiting space and can be supported by the supporting arm or limited by the limiting arm. The limiting space limits the roller in multiple directions, avoiding limiting only the lower side of the roller and preventing the roller from detaching from the roller assembly. Simultaneously, there is a movable gap between the roller and the limiting arm. The roller is rotatably connected to the metal ring and rotates along the axis of the metal ring. The peripheral wall of the roller has a roller groove for a steel wire to pass through. The steel wire is sleeved in the roller groove to facilitate the rotational resistance of the roller on the metal ring through the movable gap, improving the smoothness of the roller's rotation.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please refer to the attached document. Figures 1-5 This application provides a roller assembly for use in an automotive sunroof device. The roller assembly is used for threading steel wires and for moving the sunroof glass.

[0033] Please refer to the attached document. Figures 1-5 In this embodiment, the roller assembly includes a beam 10, a metal ring 20, and a roller 30. The beam 10 is provided with a support arm 11. The metal ring 20 is disposed on one side of the beam 10 and fixedly connected to the beam 10. The metal ring 20 is provided with a limiting arm 21, and a limiting space 21a is formed between the limiting arm 21 and the support arm 11. The roller 30 is located within the limiting space 21a and can be supported by the support arm 11 or limited by the limiting arm 21. The roller 30 is limited in multiple directions by the limiting space 21a, avoiding limiting only the lower side of the roller 30 and preventing the roller 30 of the roller assembly from detaching. Meanwhile, there is a movable gap 30a between the roller 30 and the limiting arm 21; the roller 30 is rotatably connected to the metal ring 20 and rotates along the axis of the metal ring 20; the peripheral side wall of the roller 30 is provided with a roller groove 30b, which is used for the steel wire to pass through. The steel wire is sleeved in the roller groove 30b so as to reduce the rotational resistance of the roller 30 on the metal ring 20 through the space of the movable gap 30a, thereby improving the smoothness of the rotation of the roller 30.

[0034] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the beam 10 is provided with a support arm 11; the support arm 11 protrudes from the bottom to the top of the beam 10.

[0035] The metal ring 20 is disposed on the upper side of the beam 10 and fixedly connected to the beam 10 so that the metal ring 20 can be fixed on the upper side of the beam 10; the metal ring 20 is provided with a limiting arm 21, and a limiting space 21a is formed between the limiting arm 21 and the supporting arm 11; the limiting space 21a is used to accommodate the roller 30.

[0036] The roller 30 is located within the limiting space 21a and can be supported by the support arm 11 or limited by the limiting arm 21. The limiting space 21a provides multi-directional limiting of the roller 30, avoiding limiting only the lower side of the roller 30 and preventing the roller 30 from detaching from the roller assembly. There is a movable gap 30a between the roller 30 and the limiting arm 21. The roller 30 is rotatably connected to the metal ring 20 and rotates along the axis of the metal ring 20. The peripheral wall of the roller 30 is provided with a roller groove 30b for threading a steel wire. The steel wire is sleeved within the roller groove 30b to reduce the rotational resistance of the roller 30 on the metal ring 20 through the movable gap 30a, thus improving the smoothness of the roller 30's rotation.

[0037] Please refer to the attached document. Figures 1-4 In this embodiment, lubricating oil is provided between the roller 30 and the limiting arm 21. This lubricating oil is located within the movable gap 30a and lubricates the opposing side walls of the limiting arm 21 and the roller 30. This allows the lubricating oil to fill the space of the movable gap 30a, reducing the coefficient of friction between the limiting arm 21 and the roller 30, thus decreasing the rotational resistance of the roller 30 on the limiting arm 21 and improving the smoothness of the roller 30's rotation. Simultaneously, it reduces the heat generated by friction between the limiting arm 21 and the roller 30. Optionally, the movable gap 30a is 0.05–0.1 mm to ensure sufficient space for lubricating oil filling.

[0038] Please refer to the attached document. Figures 1-5 In this embodiment, the metal ring 20 includes a ring body 22, which is arranged in a ring shape so that the roller 30 can rotate relative to the metal ring 20 through the ring body 22. The limiting arm 21 is connected to the ring body 22 in a ring shape and extends outward. The limiting arm 21 does not exceed the position of the roller 30 relative to the roller groove 30b, ensuring that the limiting arm 21 limits the upper side of the roller 30.

[0039] Please refer to the attached document. Figures 1-5 In this embodiment, the ring body 22 and the limiting arm 21 are integrally connected, which improves the connection strength between the ring body 22 and the limiting arm 21 and ensures the connection stability between the ring body 22 and the limiting arm 21; the ring body 22 is detachably connected to the beam body 10 so that the ring body 22 can be connected to or detached from the beam body 10, which improves the ease of loading and unloading the roller 30.

[0040] Please refer to the attached document. Figures 1-5In this embodiment, the ring body 22 is provided with a through hole 22a for a screw to pass through and be screwed to the beam body 10, and to press against the ring body 22. The ring body 22 is stationary relative to the beam body 10. The roller 30 rotates relative to the ring body 22 so that the ring body 22 can be detachably connected to the beam body 10 by screws. Optionally, the beam body 10 is a plastic beam body 10; the screw is a self-tapping screw.

[0041] Please refer to the attached document. Figures 1-4 In this embodiment of the application, the roller groove 30b is surrounded by the peripheral sidewall of the roller 30, and the roller groove 30b is provided with a groove bottom 30c. The steel wire is pressed against the groove bottom 30c, and the groove bottom 30c is an arc sidewall, so that the roller groove 30b can support the steel wire through the groove bottom 30c.

[0042] Please refer to the attached document. Figures 1-4 In this embodiment, the roller groove 30b has a groove side portion 30d, which is disposed on both sides of the groove bottom 30c and transitionally connected to the groove bottom 30c. The groove side portion 30d is an inclined sidewall and extends towards the groove bottom 30c to guide the steel wire and prevent the steel wire from detaching from the roller groove 30b, thus ensuring the arrangement of the steel wire relative to the roller groove 30b. At the same time, the transition connection enables the surface of the steel wire to make smooth contact with the groove side portion 30d and the groove bottom 30c, reducing the friction between the steel wire and the roller groove 30b.

[0043] In a second application embodiment, a car sunroof device includes a roller assembly. The roller assembly is part of the car sunroof device. The car sunroof device can increase natural light inside the car and improve visibility. At the same time, opening the sunroof glass can create a negative pressure zone, which helps the air inside the car to circulate, quickly eliminate odors and harmful gases, and facilitate ventilation inside the car.
