Description

Technical Field

[0001] The utility model relates to the technical field of vehicle window glass, in particular to a vehicle window glass lifting mechanism. Background Art

[0002] Car window glass is an important part of the car to provide vision, protect the occupants and maintain the interior environment. The main features and functions of car window glass include: Vision: Allows the occupants to observe the situation outside the car. Protection: Blocks external objects from entering the car to protect the safety of passengers. Sound insulation and heat insulation: Reduces the transfer of external noise and heat. Light transmittance: Ensures that there is enough light in the car. Safety performance: In the event of a collision, it can absorb energy to a certain extent and reduce damage. Anti-ultraviolet: Some car window glass can block and protect the skin of passengers. Aesthetics: Adds to the appearance and texture of the car.

[0003] The window glass lifting device of the new smart car mostly adopts the steel wire lifting method. After long-term use, the steel wire is worn and broken, resulting in the inability to lift the window glass normally, which reduces the service life of the window glass lifting device. At the same time, the existing window glass lifting device is not convenient for repairing and replacing the window glass, which reduces the functionality of the window glass lifting device. Therefore, a window glass lifting mechanism is proposed herein. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A vehicle window glass lifting mechanism includes a glass body 1 in a vehicle window main body shell and a fixing frame 2. The above-mentioned vehicle window main body shell is a component disclosed in the prior art and will not be described in detail in this scheme. The fixing frame 2 is fixedly installed in the vehicle window main body shell.

[0022] The fixed frame 2 is provided with a lifting screw 3 through a power device, and a lifting frame 4 is threadedly sleeved on the lifting screw 3. As shown in the figure, the top view of the lifting frame 4 is U-shaped. The lifting frame 4 is provided with a rotating port 8, and the lifting frame 4 is provided with two rotating ports 8. A double-headed screw 9 is provided in the rotating port 8, and the other end of the double-headed screw 9 extends to the outside of the lifting frame 4 and a fixed block is fixed at the end. A torsion spring 14 is installed between the fixed block and the lifting frame 4 to ensure that the gear 12 on the double-headed screw 9 automatically rotates and resets after losing engagement with the rack 7. This is a conventional setting.

[0023] A moving plate 10 for clamping the glass body 1 is threadedly sleeved on the double-headed screw 9, and the double-headed screw 9 is connected to the fixing frame 2 through a transmission mechanism.

[0024] The transmission mechanism includes a mounting frame 6 mounted on the fixed frame 2, a gear 12 is provided at the end of the double-headed screw 9 outside the lifting frame 4, and a rack 7 cooperating with the gear 12 is provided on the mounting frame 6. When the lifting frame 4 drives the double-headed screw 9 and other components to descend to a certain height, the gear 12 can be meshed with the rack 7.

[0025] A vertical rod 5 is provided on the fixed frame 2, and the vertical rod 5 is arranged in parallel with the lifting screw 3, and the vertical rod 5 slides through the lifting frame 4. A cross bar 13 is provided in the rotating opening 8, and the cross bar 13 is arranged in parallel with the stud screw 9, and the cross bar 13 slides through the moving plate 10. The cross bar 13 and the vertical rod 5 both play a role of limiting, effectively preventing the lifting frame 4 and the moving plate 10 from rotating with the lifting screw 3 and the stud screw 9 respectively.

[0026] A protective pad 11 is provided on the surface where the movable plate 10 contacts the glass body 1. The protective pad 11 is made of rubber and has anti-slip grooves on the surface where the protective pad 11 contacts the glass body 1. The rubber-made protective pad 11 with anti-slip grooves effectively protects the glass body 1 and prevents the movable plate 10 from causing damage to the glass body 1.

[0027] A power cavity is provided inside the fixing frame 2, and a power device is arranged in the power cavity. The power device is a motor.

[0028] When the utility model is used, the power device can drive the lifting screw 3 to rotate forward and reversely. During the forward and reverse rotation of the lifting screw 3, the lifting frame 4 can be driven to move up and down, thereby realizing the lifting operation of the glass body 1.

[0029] In this solution, when the glass body 1 is lifted or lowered daily, it will not drive the gear 12 to engage with the rack 7 when it is in the lowest position. Only when the glass body 1 needs to be disassembled, the lifting screw 3 will rotate more, so that the lifting frame 4 can continue to descend, so that the gear 12 will engage with the rack 7, so that the double-headed screw 9 will rotate, and the moving plate 10 threadedly mounted thereon will move and move away from the glass body 1, thereby releasing the clamping of the glass body 1, making it easier to take out the glass body 1 for replacement or maintenance.

[0030] The forward and reverse rotation and the forward and reverse amplitude of the above-mentioned power device can be achieved by relying on existing technical equipment, and the specific equipment structure and working principle are not described in detail here.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
