Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and in particular to a vehicle seat belt push reminder device. Background Art

[0002] Seatbelts are a critical component of a vehicle's safety system. During normal high-speed driving, occupants' sitting positions can be shaken by changes in traffic and road conditions, such as braking, turning, or acceleration caused by changes in the road surface. Without seatbelt restraint, high acceleration can cause occupants to collide with components within the vehicle. In extreme situations, such as a collision, without seatbelt restraint, occupants can be thrown from the vehicle due to the extreme acceleration. When the airbag pops out and deploys, the occupant's body is pulled forward by the acceleration, contacting the incompletely deployed airbag. This combined impact can result in even more severe injuries. Therefore, seatbelts must be worn when riding in high-speed vehicles.

[0003] Most vehicles currently have seatbelts installed on their occupants, such as the driver and front passenger, which consist of a seatbelt, a buckle, and a reminder module. Occupants may choose not to wear their seatbelts due to a lack of safety awareness and find them uncomfortable. The reminder module will sound a warning tone when it detects an unbelted occupant.

[0004] While most existing vehicles can sound a warning if a passenger or driver is not wearing a seatbelt after the vehicle is unlocked, the warning volume is low and difficult to detect, which can easily lead to passengers or drivers driving without their seatbelts. Since the seatbelts are located inside the B- and C-pillars of the vehicle and extend out of the exit, once the passenger or driver notices it, they must lean sideways and turn their upper body to access the seatbelt buckle, making the seatbelt fastening process cumbersome and inconvenient. Therefore, improvements are needed. Summary of the Invention

[0005] The object of the present invention is to address the defects and shortcomings of the existing technology and provide a vehicle seat belt push reminder device, which can automatically detect whether there is an occupant on the vehicle seat, and when an occupant is detected, control the seat belt reminder device to send the seat belt to the front of the occupant's shoulder on the window side and put it into the occupant's field of vision in a normal sitting position. In addition to reminding the occupant to fasten the seat belt, it can also facilitate the occupant to fasten the seat belt when the seat belt is grabbed to a better position that the occupant can reach, avoiding the problem of the existing design that the user needs to turn over the body to pull the seat belt when fastening the seat belt, which makes fastening the seat belt inconvenient. The present invention has the advantages of good reminder effect, convenient seat belt fastening, simple operation, stable pushing, and increased sense of respect for the occupant.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a vehicle seat belt push reminder device, which is installed inside the inner wall of the vehicle, including: a first detection unit for detecting the occupancy status of the vehicle seat; a push reminder component movably installed on the inner wall of the vehicle and located at the seat belt outlet on the inner wall of the vehicle, when the first detection unit detects that there is an occupant in the vehicle seat, the push reminder component is used to push the seat belt to the front of the occupant's shoulder on the window side and put it into the field of view of the occupant in a normal sitting state; a driving component arranged in the inner wall of the vehicle and assembled with the push reminder component for providing power for the movement of the push reminder component; a second detection unit arranged on the push reminder component for detecting whether the pushed seat belt is detached from the push reminder component; and a control element arranged on the vehicle, one end of which is connected to both the first detection unit and the second detection unit and the other end is connected to the drive component, for receiving detection signals emitted by the first detection unit and the second detection unit and controlling the opening or closing of the drive component according to the detection signal.
