Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, specifically to an automotive sunroof lifter. Background Technology

[0002] A car sunroof is installed on the roof of a vehicle and can effectively circulate air inside the car, increasing the intake of fresh air. At the same time, a car sunroof can also expand the field of vision. Car sunroofs can be roughly divided into: sliding type, concealed type, concealed and tilting type, panoramic type and curtain type, etc., and are mainly installed on commercial SUVs, sedans and other models.

[0003] Chinese Patent Publication No. CN222973179U discloses a mechanical component for raising and lowering a car sunroof, including a car roof. L-shaped plates are fixedly connected to both the front and rear sides of the car roof, and a sunroof groove is formed on one side of the top of the car roof. In this mechanical component, a pusher on one of the moving blocks compresses a connecting block, causing the connecting block to drive a convex rod to slide inside the convex groove. A second return spring at one end of the convex rod is in an elastically compressed state. The convex rod, through a telescopic rod, a first return spring, an elongated pressing plate, and the convex plate, moves the sunroof body on the limiting frame, moving it away from the sunroof groove to a position below the car roof. This structural design allows the sunroof body to be opened or closed simply by activating a forward and reverse motor, enabling rapid opening without the need for multiple electric push rods, thus avoiding increased maintenance costs.

[0004] In the aforementioned prior art, when only the sunroof body is raised and lowered to open, since no protective device for debris is provided, after the sunroof body is moved out of the sunroof groove, the gap formed between it and the car roof and L-shaped panel is completely exposed. During driving, external debris such as leaves and stones can easily enter and pollute the car interior environment. Therefore, a car sunroof regulator is needed to meet people's needs. Utility Model Content

[0005] The purpose of this utility model is to provide an automotive sunroof lifter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car sunroof lifter, comprising a sunroof body and a fixed frame; two bidirectional lead screws are symmetrically and rotatably installed inside the fixed frame, and a lifting structure is connected to the two bidirectional lead screws; a connecting plate is installed below the sunroof body, and a sliding structure is connected to the connecting plate; an installation frame is detachably installed below the fixed frame, and an interception structure is connected to the installation frame.

[0007] Preferably, the lifting structure includes four threaded sliders, which are symmetrically threaded onto two bidirectional lead screws. A motor is installed on the inner wall of the fixed frame, and the output end of the motor is installed on the corresponding bidirectional lead screw.

[0010] Preferably, the sliding structure includes an electric push rod, which is installed on one side of the movable frame. The telescopic end of the electric push rod is installed on one side of the connecting plate. A T-shaped groove is provided inside the movable frame. A T-shaped strip is slidably installed in the T-shaped groove. The T-shaped strip is installed below the sunroof body. The electric push rod and the motor are electrically connected to the same control module through wires.

[0011] Preferably, the interception structure includes an elastic mesh sleeve, which is installed on one side of the first mounting frame, and a second mounting frame is installed on the elastic mesh sleeve. The second mounting frame is detachably installed on the inner wall of the movable frame.

Detailed Implementation

[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] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a car sunroof lifter, including a sunroof body 100 and a fixed frame 101; two bidirectional lead screws 200 are symmetrically and rotatably installed inside the fixed frame 101, and a lifting structure is connected to the two bidirectional lead screws 200; a connecting plate 300 is installed below the sunroof body 100, and a sliding structure is connected to the connecting plate 300; an installation frame 400 is detachably installed below the fixed frame 101, and an interception structure is connected to the installation frame 400.

[0024] In this embodiment, a car sunroof lifter operates by controlling the lifting structure through a control module to drive the sunroof body 100 to lift and lower, opening or closing the opening of the fixed frame 101. During the lifting and lowering process, the interception structure unfolds simultaneously to intercept debris. When it is necessary to fully open the sunroof, the sunroof body 100 is driven to slide laterally through the sliding structure to achieve the fully open state of the sunroof. The whole process is highly automated and has the function of intercepting debris, improving the safety and convenience of using the sunroof.

[0025] Furthermore, the lifting structure includes four threaded sliders 201, which are symmetrically threaded onto two bidirectional lead screws 200. A motor 202 is installed on the inner wall of the fixed frame 101, and the output end of the motor 202 is installed on the corresponding bidirectional lead screw 200. A connecting rod 203 is rotatably installed on one side of each of the four threaded sliders 201. One end of each of the four connecting rods 203 is rotatably installed on the same movable frame 204. The movable frame 204 is slidably installed below the sunroof body 100, and four connecting rods 201 are symmetrically installed on one side of the movable frame 204. Four guide slides 209 are slidably installed on the inner wall of the fixed frame 101. Four guide grooves 205 are symmetrically opened on the inner wall of the fixed frame 101. Four threaded sliders 201 are slidably installed in the four guide grooves 205 respectively. A connecting shaft 206 is rotatably installed inside the fixed frame 101. Both ends of the connecting shaft 206 are equipped with bevel gears 207. One end of each of the two bidirectional lead screws 200 is equipped with a bevel gear 208. The two bevel gears 208 mesh with the two bevel gears 207 respectively.

[0026] The motor 202 of the lifting structure is connected to the vehicle power supply via wires. After the motor 202 is started by the control module, the output end of the motor 202 drives the corresponding bidirectional lead screw 200 to rotate. The bidirectional lead screw 200 drives the second bevel gear 208 at one end to rotate. Through the meshing transmission between the second bevel gear 208 and the first bevel gear 207, the connecting shaft 206 and the first bevel gear 207 and the second bevel gear 208 at the other end rotate synchronously, ultimately achieving synchronous rotation of the two bidirectional lead screws 200. Since the threads at both ends of the bidirectional lead screw 200 face opposite directions and are adapted to the threaded slider 201, rotation will drive the threads at both ends... The threaded sliders 201 move closer or further apart synchronously along the guide groove 205. When the threaded sliders 201 on both sides move closer, they drive one end of the two connecting rods 203 to retract, and the other end of the connecting rods 203 rotates on the inner wall of the movable frame 204 and pushes the movable frame 204 to rise. The movable frame 204 drives the sunroof body 100 to rise synchronously and open the opening. Conversely, when the threaded sliders 201 move further apart, the sunroof body 100 descends and closes. When the movable frame 204 rises and falls, the guide strip 209 slides along the inner wall of the fixed frame 101 to form precise guidance, avoid the movable frame 204 from tilting or deviating, and ensure that the sunroof rises and falls smoothly.

[0027] Furthermore, the sliding structure includes an electric push rod 301, which is installed on one side of the movable frame 204. The telescopic end of the electric push rod 301 is installed on one side of the connecting plate 300. A T-shaped groove 302 is provided inside the movable frame 204. A T-shaped strip 303 is slidably installed in the T-shaped groove 302. The T-shaped strip 303 is installed below the sunroof body 100. The electric push rod 301 and the motor 202 are electrically connected to the same control module through wires.

[0028] When the skylight body 100 is raised to its maximum height via the lifting structure, if it is necessary to fully open the skylight, the electric push rod 301 is activated by the control module. Its telescopic end drives the connecting plate 300 to move laterally, and the connecting plate 300 drives the skylight body 100 to move synchronously. At this time, the T-shaped strip 303 under the skylight body slides along the T-shaped groove 302 of the movable frame 204 to form a stable guide. This structure, through the cooperation of the T-shaped groove 302 and the T-shaped strip 303, ensures that the skylight body 100 will not detach from the movable frame 204 during the sliding process, thereby improving the ventilation effect.

[0029] Example 2: Figure 2-3 In order to intercept external debris when the sunroof body 100 is raised, an interception structure is arranged. The interception structure includes an elastic mesh sleeve 401, which is installed on one side of the mounting frame 400. A second mounting frame 402 is installed on the elastic mesh sleeve 401. The second mounting frame 402 is detachably installed on the inner wall of the movable frame 204. Several mounting screws 403 are inserted inside the first mounting frame 400. One end of the mounting screws 403 is threaded inside the fixed frame 101. Several mounting screws 404 are inserted inside the second mounting frame 402. One end of the mounting screws 404 is threaded inside the movable frame 204.

[0030] In this embodiment, the interception structure and the lifting structure work together. The interception structure is fixed to the bottom of the fixed frame 101 by the first mounting frame 400 and the first mounting screw 403, and fixed to the inner wall of the movable frame 204 by the second mounting frame 402 and the second mounting screw 404, so as to achieve tension and fixation of the elastic net sleeve 401. When the movable frame 204 rises through the lifting structure, it will drive the second mounting frame 402 to rise synchronously, so that the elastic net sleeve 401 is stretched and unfolded, which just blocks the gap between the movable frame 204 and the fixed frame 101, effectively intercepting the debris falling from the outside. When it is necessary to clean or replace the elastic net sleeve 401, simply rotate and unscrew the first mounting screw 403 and the second mounting screw 404 to disassemble the first mounting frame 400, the second mounting frame 402 and the elastic net sleeve 401 as a whole, which is convenient to operate.
