Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, specifically to a sunroof motor with anti-pinch effect. Background Technology

[0002] In today's rapidly developing automotive industry, sunroofs, as an important feature for improving in-vehicle comfort and ventilation, are widely used in various car models. The sunroof motor, as the core component driving the opening and closing of the sunroof, directly affects the passenger experience and personal safety.

[0003] However, some sunroof motors on the market currently lack anti-pinch functionality. When these motors encounter obstacles (such as a passenger's fingers or head) during the closing process, they fail to detect and stop in time, causing the sunroof to continue pressing down. This can easily cause serious injuries such as pinching, posing a significant safety hazard during vehicle use, especially in situations involving children. Children, lacking self-protection awareness, are more prone to such accidents, placing a heavy burden on families and society. Furthermore, some existing sunroof designs are flawed, often employing rigid connections. When the sunroof encounters a person or other obstacle during closing, the lack of an effective buffer structure results in a significant impact force between the sunroof and the obstacle. This not only exacerbates the injury to the passenger but may also damage the sunroof itself and other vehicle components, increasing maintenance costs and usage risks. Therefore, we propose a sunroof motor with anti-pinch functionality to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a sunroof motor with anti-pinch effect, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A sunroof motor with anti-pinch effect includes a roof, on which a rectangular groove is formed. Grooves are formed on the inner walls of both sides of the roof, and the grooves communicate with one inner wall of the rectangular groove. A lead screw is rotatably connected to the inner wall of the other side of the groove. A pulley is fixedly connected to the lead screw, and the two pulleys are driven by the same belt. A motor and a controller are fixedly connected to one inner wall of the rectangular groove. The end of one of the lead screws is fixedly connected to the output shaft of the motor. A common moving plate is threaded onto both lead screws. A sunroof glass is provided on one side of the moving plate. The roof has a buffer groove, and multiple positioning rods are fixedly connected to the inner wall of one side of the buffer groove. The same buffer plate is slidably connected to the multiple positioning rods. Multiple buffer springs are fixedly connected to one side of the buffer plate and the inner wall of one side of the buffer groove. Multiple arc-shaped spring pieces are fixedly connected between one side of the buffer plate and the inner wall of one side of the buffer groove. Multiple mounting grooves are opened on the other side of the buffer plate. A laser emitter is installed on the inner wall of one side of the mounting groove. A storage groove is opened on the inner wall of the other side of the roof. A laser receiver is installed on the inner wall of one side of the storage groove. The laser receiver corresponds to the corresponding laser emitter.

[0009] Furthermore, the buffer spring is movably sleeved on the corresponding positioning rod.

[0010] Furthermore, the outer side of the movable plate is slidably connected to the inner wall of the groove.

[0011] Furthermore, the motor, controller, laser emitter, and laser receiver are electrically connected via conductive lines.

[0013] Furthermore, the movable plate has two threaded holes, and the movable plate is threadedly connected to the corresponding lead screw through the threaded holes.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a sunroof motor with anti-pinch effect, which has the following beneficial effects:

[0016] This invention utilizes a controller to receive commands and start a motor. Through pulleys and belts, a lead screw moves a sliding plate, causing the sunroof glass to open and close along a groove. A laser emitter continuously transmits laser signals to a laser receiver. If an obstacle enters the light curtain area during the sunroof's closing process, the laser signal is blocked. The laser receiver feeds back the signal change to the controller, immediately stopping the motor. When a buffer plate encounters a person or obstacle, it slides on a positioning rod and compresses a buffer spring, providing cushioning. Simultaneously, the buffer plate compresses an arc-shaped spring, further reducing the impact on obstacles and lowering the risk of injury. The combination of laser sensing and a buffer structure provides anti-pinch protection. The laser sensor monitors obstacles in real time and triggers the anti-pinch logic, while the buffer structure provides physical cushioning in extreme situations, ensuring safe use.

[0023] 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.

[0024] Example

[0025] like Figure 1-5 As shown, an embodiment of this utility model discloses a sunroof motor with anti-pinch effect, including a roof 1. A rectangular groove 2 is formed on the roof 1. Grooves 3 are formed on the inner walls of both sides of the roof 1. The grooves 3 are connected to one inner wall of the rectangular groove 2. A lead screw 4 is rotatably connected to the inner wall of the other side of the groove 3. A pulley 5 is fixedly connected to the lead screw 4. The two pulleys 5 are driven by the same belt 6. A motor 7 and a controller 8 are fixedly connected to one inner wall of the rectangular groove 2. The end of one of the lead screws 4 is fixedly connected to the output shaft of the motor 7. The two lead screws 4 are threadedly connected to the same moving plate 9. A sunroof glass 10 is provided on one side of the moving plate 9. A buffer groove 19 is provided. Multiple positioning rods 11 are fixedly connected to one inner wall of the buffer groove 19. The same buffer plate 12 is slidably connected to the multiple positioning rods 11. Multiple buffer springs 13 are fixedly connected to one side of the buffer plate 12 and one inner wall of the buffer groove 19. Multiple arc-shaped spring pieces 14 are fixedly connected between one side of the buffer plate 12 and one inner wall of the buffer groove 19. Multiple mounting grooves 15 are provided on the other side of the buffer plate 12. A laser emitter 16 is provided on one inner wall of one side of the mounting groove 15. A storage groove 17 is provided on the other inner wall of the roof 1. A laser receiver 18 is provided on one inner wall of one side of the storage groove 17. The laser receiver 18 corresponds one-to-one with the corresponding laser emitter 16.

[0026] During use, this motor 7 achieves basic opening and closing functions through the lead screw 4, and combines laser sensing and buffer structure to achieve anti-pinch protection. The laser sensor monitors obstacles in real time and triggers the anti-pinch logic, while the buffer structure provides physical buffering in extreme cases to ensure safe use.

[0027] In use, when the driver or passenger operates the sunroof switch, the controller 8 receives the command and starts the motor 7. The motor 7 is driven by the pulley 5 and the belt 6, causing the two lead screws 4 to rotate simultaneously. The lead screws 4 drive the moving plate 9 to slide on the groove 3. The movement of the moving plate 9 causes the sunroof glass 10 to open and close along the groove 3. When the moving plate 9 moves, the laser emitter 16 continuously emits laser signals to the laser receiver 18, forming an invisible light curtain. If an obstacle (such as a finger or debris) enters the light curtain area during the sunroof closing process, the laser signal is blocked, and the laser receiver 18 cannot receive the corresponding signal. The laser receiver 18 feeds back the signal change to the controller 8. The controller 8 determines that the anti-pinch trigger has been activated and immediately stops the motor 7. When the moving plate 9 moves, it drives the buffer plate 12 to move. When the buffer plate 12 touches a person or obstacle, the buffer plate 12 slides on the positioning rod 11. During the movement, the buffer plate 12 compresses the buffer spring 13. Under the action of the buffer spring 13's own elasticity, it plays a buffering role. At the same time, the buffer plate 12 squeezes the arc-shaped spring piece 14, which further buffers the impact on the obstacle and reduces the risk of injury.

[0028] In some embodiments, the buffer spring 13 is movably sleeved on the corresponding positioning rod 11.

[0029] The positioning rod 11 provides a clear movement trajectory for the buffer spring 13, ensuring that the buffer spring 13 is always compressed and reset along the axial direction, avoiding displacement.

[0030] In some embodiments, the outer side of the movable plate 9 is slidably connected to the inner wall of the groove 3.

[0031] The inner wall of the groove 3 provides lateral support for the movable plate 9, ensuring that it always moves along a straight trajectory and avoids deviation.

[0032] In some embodiments, the motor 7, controller 8, laser emitter 16, and laser receiver 18 are electrically connected via conductive lines.

[0033] In some embodiments, a plurality of positioning grooves are provided on the other side of the buffer plate 12, and the buffer plate 12 is slidably connected to the corresponding positioning rod 11 through the positioning grooves.

[0034] In some embodiments, the movable plate 9 has two threaded holes, and the movable plate 9 is threadedly connected to the corresponding lead screw 4 through the threaded holes.

[0035] The cooperation between the double lead screw 4 and the double threaded hole ensures that the moving plate 9 is subjected to force on both sides simultaneously, ensuring that the sunroof glass 10 opens and closes smoothly along the groove 3, avoiding jamming or tilting.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
