[0024] This application is made based on the inventor's discovery and recognition of the following facts and problems:
[0025] The pre-tensioning force-limiting seat belt tightens the restraint force by activating the pre-tensioning device at the moment of a collision, so that the restraint force is constantly output as the occupant lunges forward due to inertia, so that the occupant maintains a stable restraint with a moderate magnitude throughout the collision process, thereby greatly reducing the collision injury of the occupant. During the entire collision movement process, as the human body lunges forward, the seat belt webbing extends, and the angle of the guide ring is lifted, so that the webbing smoothly passes through the guide ring.
[0026] In some vehicles in the related art, such as commercial vehicles, the man-machine layout is relatively compact, the distance between the fixed point of the guide ring and the occupant is close, and in addition, the front collision energy absorption space is small, the collision deceleration is large, and the guide ring cannot rotate in time at the moment of collision, resulting in the seat belt piling up at the guide ring, resulting in abnormal seat belt force-limiting values and poor occupant restraint performance.
[0027] In some guide ring angle adjustment systems in the related art, by detecting the occurrence of a collision, the guide ring is actively driven to lift at the moment of the collision, intending to improve the problem that the angle of the guide ring is insufficiently lifted during the collision, resulting in the seat belt piling up at the guide ring. However, when the collision occurs, the seat belt has already started to tighten, and the driving of the guide ring requires a certain amount of time. It is difficult for the guide ring to rotate to the optimal position in time, and the seat belt will still pile up to a certain extent, affecting the restraint performance of the occupant.
[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] The following describes the guide ring angle adjustment system 1 according to an embodiment of the present utility model with reference to the drawings.
[0032] As Figure 1 and Figure 2 shown, the guide ring angle adjustment system 1 according to an embodiment of the present utility model includes a guide ring 10, a seat belt wearing detection device, a guide ring angle detection device 20, and the guide ring driving device.
[0033] Specifically, the guide ring 10 is rotatably provided inside the vehicle pillar, such as inside the B pillar. The seat belt webbing passes through the guide ring 10 and the seat belt tongue.
[0034] The seat belt wearing detection device is adapted to detect whether the seat belt tongue is inserted into the seat belt buckle. The guide ring angle detection device 20 is adapted to detect the rotation angle of the guide ring 10. The seat belt wearing detection device is electrically connected to the guide ring angle detection device 20. The guide ring driving device is adapted to drive the guide ring 10 to rotate, and the guide ring driving device is electrically connected to the guide ring angle detection device 20.
[0035] Specifically, after the occupant gets into the vehicle and fastens the seat belt, inserts the seat belt tongue into the seat belt buckle, the seat belt wearing detection device detects that the seat belt tongue is inserted into the seat belt buckle and sends a signal to the guide ring angle detection device 20.
[0036] The guide ring angle detection device 20 starts to detect the rotation angle of the guide ring 10.
[0037] If the rotation angle of the guide ring 10 is less than the predetermined angle, it indicates that the upward lifting angle of the guide ring 10 is insufficient. The guide ring angle detection device 20 sends a signal to the guide ring driving device.
[0038] The guide ring driving device drives the guide ring 10 to rotate until the guide ring 10 rotates to the predetermined angle.
[0039] Thus, after the user fastens the seat belt, the guide ring 10 can be maintained at the predetermined angle.
[0040] According to the guide ring angle adjustment system 1 of the embodiment of the present invention, by providing the guide ring angle detection device 20 and the guide ring driving device, the guide ring angle detection device 20 can be used to detect the rotation angle of the guide ring 10. If it is found that the rotation angle of the guide ring 10 is less than the predetermined angle, it indicates that the upward lifting angle of the guide ring 10 is insufficient, and the problem of seat belt accumulation is likely to occur. By driving the guide ring 10 to rotate through the guide ring driving device, the guide ring 10 rotates and is maintained at the predetermined angle. Compared with the vehicles in the related art, the problem of seat belt accumulation caused by inappropriate angle of the guide ring 10 during a collision can be avoided, the force limiting value of the seat belt can be ensured to be stable, the restraint of the seat belt on the occupant can be ensured, and the reliability of the guide ring angle adjustment system 1 can be improved. Thus, the guide ring angles can be adjusted for different vehicle models, occupants of different body types, different sitting postures and positions of the occupants, so that the guide ring can rotate and be maintained at a suitable angle, and the applicability of the guide ring angle adjustment system 1 can be improved.
[0041] Moreover, by providing the seat belt wearing detection device, the seat belt wearing situation can be detected by the seat belt wearing detection device. After the occupant fastens the seat belt, the guide ring angle detection device 20 can be controlled to detect the angle of the guide ring 10 and the guide ring driving device can be controlled to drive the guide ring 10 to rotate to the predetermined angle. Compared with the technical solution in the related art that the guide ring angle is lifted again when a collision occurs, the guide ring 10 can be kept at a suitable angle all the time before a possible collision occurs, and the problem of seat belt accumulation caused by driving the guide ring to rotate after the collision occurs and the guide ring not reaching the predetermined angle in time can be avoided, which can more effectively and timely avoid the problem of seat belt accumulation, further ensure the stability of the force limiting value of the seat belt, ensure the restraint of the seat belt on the occupant, and improve the reliability of the guide ring angle adjustment system 1.
[0042] Therefore, the guide ring angle adjustment system 1 according to the embodiments of the present invention can avoid the accumulation of seat belts, and has advantages such as good applicability and strong reliability.
[0043] The guide ring angle adjustment system 1 according to specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0044] In some specific embodiments of the present invention, such as Figure 1 and Figure 2 shown, the guide ring angle adjustment system 1 according to the embodiments of the present invention includes a guide ring 10, a seat belt wearing detection device, a guide ring angle detection device 20, and the guide ring driving device.
[0045] Specifically, the guide ring angle detection device 20 is configured to detect the rotation angle of the guide ring 10 after the seat belt wearing detection device detects that the seat belt tongue is inserted into the seat belt buckle. Thus, after the occupant wears the seat belt, the guide ring angle detection device 20 can be controlled to detect the angle of the guide ring 10 and control the guide ring driving device to drive the guide ring 10 to rotate to a predetermined angle, avoiding the problem that the guide ring cannot reach the predetermined angle in time after the collision occurs, resulting in the accumulation of the seat belt. It can more effectively and timely avoid the problem of seat belt accumulation, further ensure the stability of the force limiting value of the seat belt, ensure the restraint of the seat belt on the occupant, and improve the reliability of the guide ring angle adjustment system 1.
[0046] More specifically, the rotation angle is the angle of rotation between the current position of the guide ring 10 and the natural drooping state of the guide ring 10. The guide ring driving device is configured to drive the guide ring 10 to rotate to the predetermined angle when the guide ring angle detection device 20 detects that the rotation angle is less than the predetermined angle. Specifically, the guide ring driving device can drive the guide ring 10 to rotate by the difference between the rotation angle and the predetermined angle. This can facilitate the judgment of whether the guide ring 10 rotates to the predetermined angle, facilitate the guide ring driving device to drive the guide ring 10 to rotate and stay at the predetermined angle, and avoid the accumulation of the seat belt.
[0047] Optionally, as Figure 1 and Figure 2 shown, both the guide ring angle detection device 20 and the guide ring driving device are provided on the guide ring 10. This can facilitate the guide ring angle detection device 20 to detect the rotation angle of the guide ring 10, facilitate the guide ring driving device to drive the guide ring 10 to rotate, and facilitate the electrical connection between the guide ring angle detection device 20 and the guide ring driving device to facilitate signal transmission.

This facilitates rotatably arranging the guide ring 10 on the vehicle body column.
[0049] In some embodiments, the guide ring driving device is a motor 30 and is in transmission connection with the guide ring rotating shaft 40. This facilitates driving the guide ring 10 to rotate by the guide ring driving device.
[0050] In some embodiments, the guide ring driving device includes a motor 30 and a threaded guide rail 50. The motor is arranged on the guide ring rotating shaft 40, and the motor 30 has a threaded rotating shaft 31. The threaded guide rail 50 is arranged on the guide ring 10 and extends in an arc shape, and the threaded guide rail 50 meshes with the threaded rotating shaft 31. In this way, the threaded rotating shaft 31 can be driven to rotate by the motor 30, and the guide ring 10 can be driven to rotate relative to the guide ring rotating shaft 40 through the meshing of the threaded rotating shaft 31 and the threaded guide rail 50.
[0051] Advantageously, as Figure 2 shown in Figure 2 , the guide ring 10 is covered with a cover 60, and both the guide ring angle detection device 20 and the guide ring driving device are located inside the cover 60.
