[0030] This application is based on the inventor's discovery and recognition of the following facts and problems:

[0031] The pre-tensioning and force-limiting seat belt tightens the restraining force by activating the pre-tensioning device at the moment of a collision, so that the restraining 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 guiding ring is lifted, so that the webbing smoothly passes through the guiding ring.

[0032] 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 guiding ring and the occupant is close, and in addition, the front collision energy absorption space is small, the collision deceleration is large, and the guiding ring cannot rotate in time at the moment of collision, resulting in the accumulation of the seat belt at the guiding ring, resulting in abnormal seat belt force-limiting values and poor occupant restraint performance.

[0033] In some guiding ring angle adjustment systems in the related art, upon detecting a collision, the system actively drives the guiding ring to lift up during the collision, aiming to improve the problem that the guiding ring fails to lift up sufficiently during a collision, resulting in the seat belt piling up at the guiding ring. However, when the collision occurs, the seat belt has already started to tighten, and it takes a certain amount of time to drive the guiding ring. It is difficult for the guiding ring to rotate to the optimal position in a timely manner, and the seat belt will still pile up to a certain extent, affecting the restraint performance for the occupant.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The guiding ring angle adjustment system 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] As Figure 1 and Figure 2 shown, the guiding ring angle adjustment system 1 according to an embodiment of the present invention includes a guiding ring 10, a seat belt wearing detection device, a guiding ring angle detection device 20, and the guiding ring driving device.

[0039] Specifically, the guide ring 10 is rotatably provided inside the column of the vehicle, such as inside the B-pillar. The webbing of the seat belt passes through the guide ring 10 and the seat belt tongue.

[0040] 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, and 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.

[0041] Specifically, after the occupant gets into the vehicle and wears 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.

[0042] The guide ring angle detection device 20 starts to detect the rotation angle of the guide ring 10.

[0043] If the rotation angle of the guide ring 10 is less than the predetermined angle, it indicates that the upward lift angle of the guide ring 10 is insufficient, and the guide ring angle detection device 20 sends a signal to the guide ring driving device.

[0044] It should be understood here that the "predetermined angle" refers to a reasonable angle to prevent the seat belt from piling up, which is related to factors such as the vehicle model, the installation position of the guide ring, and the driver's body type. Those skilled in the art can obtain it through actual situations, big data, limited experiments, etc.

[0045] The guide ring driving device drives the guide ring 10 to rotate until the guide ring 10 rotates to the predetermined angle.

[0046] Thus, after the user wears the seat belt, the guide ring 10 can be maintained at the predetermined angle.

[0047] According to the guiding ring angle adjustment system 1 of an embodiment of the present invention, by providing a guiding ring angle detection device 20 and the guiding ring driving device, the rotation angle of the guiding ring 10 can be detected by the guiding ring angle detection device 20. If it is found that the rotation angle of the guiding ring 10 is less than a predetermined angle, it indicates that the upward lifting angle of the guiding ring 10 is insufficient, and the problem of seat belt accumulation is likely to occur. The guiding ring 10 is driven to rotate by the guiding ring driving device, so that the guiding ring 10 rotates and remains at the predetermined angle. Compared with the vehicles in the related art, the problem of seat belt accumulation caused by inappropriate angle of the guiding ring 10 during a collision can be avoided, the force limiting value of the seat belt can be ensured to be stable, the restraint on the occupant by the seat belt can be ensured, and the reliability of the guiding ring angle adjustment system 1 can be improved. Thus, different guiding 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 guiding ring can rotate and remain at a suitable angle, and the applicability of the guiding ring angle adjustment system 1 can be improved.

[0048] Moreover, by providing the seat belt wearing detection device, the wearing condition of the seat belt can be detected by the seat belt wearing detection device. After the occupant wears the seat belt, the guiding ring angle detection device 20 can be controlled to detect the angle of the guiding ring 10 and the guiding ring driving device can be controlled to drive the guiding ring 10 to rotate to the predetermined angle. Compared with the technical solution in the related art that the guiding ring angle is lifted again during a collision, the guiding 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 guiding ring to rotate after the collision occurs and the guiding ring cannot reach the predetermined angle in time can be avoided. The problem of seat belt accumulation can be more effectively and timely avoided, the force limiting value of the seat belt can be further ensured to be stable, the restraint on the occupant by the seat belt can be ensured, and the reliability of the guiding ring angle adjustment system 1 can be improved.

[0049] Therefore, the guiding ring angle adjustment system 1 according to an embodiment of the present invention can avoid seat belt accumulation and has the advantages of good applicability and strong reliability.

[0050] Next, the guiding ring angle adjustment system 1 according to specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0051] In some specific embodiments of the present invention, as Figure 1 and Figure 2 shown, the guiding ring angle adjustment system 1 according to an embodiment of the present invention includes a guiding ring 10, a seat belt wearing detection device, a guiding ring angle detection device 20 and the guiding ring driving device.

[0052] 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. Therefore, 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, so as to avoid the guide ring being driven to rotate after a collision, resulting in the guide ring failing to reach the predetermined angle in time and causing the seat belt to accumulate. This can more effectively and timely avoid the problem of seat belt accumulation, further ensure the stability of the force limit 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.

[0053] More specifically, the rotation angle is the rotation angle 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 makes it easy to determine whether the guide ring 10 has rotated to the predetermined angle, and makes it easy for the guide ring driving device to drive the guide ring 10 to rotate and maintain it at the predetermined angle to avoid the accumulation of the seat belt.

[0054] Alternatively, if Figure 1 and Figure 2 As shown, the guide ring angle detection device 20 and the guide ring driving device are both arranged on the guide ring 10. This makes it easy for the guide ring angle detection device 20 to detect the rotation angle of the guide ring 10, for the guide ring driving device to drive the guide ring 10 to rotate, and for the guide ring angle detection device 20 and the guide ring driving device to be electrically connected for signal transmission.

[0055] Figure 1 and Figure 2 The guide ring angle adjustment system 1 according to some examples of the present invention is shown. Figure 1 and Figure 2 As shown, the guide ring angle adjustment system 1 further comprises a guide ring rotating shaft 40, which is mounted on the vehicle body pillar, and the guide ring 10 is rotatably arranged on the guide ring rotating shaft 40. In this way, it is convenient to rotatably arrange the guide ring 10 on the vehicle body pillar.

[0056] In some embodiments, the guide ring driving device is a motor 30 and is in driving connection with the guide ring rotating shaft 40. This makes it easier for the guide ring driving device to drive the guide ring 10 to rotate.

[0057] 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 motor 30 can drive the threaded rotating shaft 31 to rotate, and through the meshing of the threaded rotating shaft 31 and the threaded guide rail 50, the guide ring 10 can be driven to rotate relative to the guide ring rotating shaft 40.

[0058] Advantageously, as Figure 2 shown, 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. In this way, the cover 60 can be used to protect the internal structure, prevent the internal structure from being exposed, and make the appearance of the guide ring angle adjustment system 1 more neat and beautiful.
