DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0057] With the continuous development of intelligent cockpit technology, new types of seats such as zero-gravity seats, multi-posture seats and long sliding rail seats are emerging in an endless stream, but the seat belt system that matches the seats is still immovable, and the adjustable part is limited to one fixed point, the seat belt height adjuster. The free and large-range movement of the seat system is in sharp contrast to the fixed and non-adjustable seat belt system, which poses a huge hidden danger to the safety of the passengers in the car.

[0058] The travel of the long slide seat is far greater than the coverage of the existing seat belt. The common seat travel is 200 to 300 mm, while the long slide seat travel is generally more than 500 mm. After the occupant moves the long slide seat, there is generally a gap of more than 100 mm between the seat belt and the occupant, which cannot protect the occupant. The seat belt does not fit well in the waist and abdomen area of ​​the occupant, and the wearing comfort is not good.

[0059] Based on this, the embodiments of the present disclosure provide a seat belt buckle adjustment device and control method, a storage medium and a vehicle.

[0060] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the seat belt buckle adjustment device 100 provided by the embodiment of the present disclosure includes: a first guide rail 1, a slider 2, a buckle body 3 and a first driving member 6; the slider 2 is slidably matched with the first guide rail 1, and the slider 2 is provided with a first toothed structure 21, and the first toothed structure 21 extends along the length direction of the first guide rail 1, and the first toothed structure 21 can be a rack. The first gear 22 is meshed with the first toothed structure 21; the buckle body 3 is rotatably connected with the slider 2, and the buckle body 3 is provided with a second gear, and the second gear is fixed to the buckle body 3; the first driving member 6 can selectively drive the first gear 22 or the second gear. When the first driving member 6 drives the first gear 22, the first gear 22 rotates, and the first gear 22 is meshed with the first toothed structure 21, so that the slider provided with the first toothed structure 21 can be moved along the first guide rail, thereby causing the buckle body 3 set on the slider 2 to translate. When the first driving member 6 drives the second gear, the second gear can be rotated, thereby causing the second gear to drive the lock body 3 to rotate. By selectively driving the first gear 22 or the second gear by the first driving member 6, the safety belt 5 connected to the lock body 3 can be made to fit the occupant, thereby effectively protecting and restraining the occupant and improving the safety of the occupant.

[0061] When the first guide rail 1 extends along the front-rear direction X of the vehicle, the first driving member 6 can switch between the two degrees of freedom of forward and backward movement in X and rotation around the Y axis. The buckle tongue 7 of the safety belt 5 can not only move in the X direction, but also adjust the appropriate angle around the Y axis to make the safety belt 5 fit the human body better.

[0062] In this embodiment, the locking tongue 7 of the safety belt 5 is inserted into the buckle body 3. When the slider 2 moves, the buckle body 3 and the locking tongue 7 inserted into the buckle body 3 are driven to move, and the safety belt 5 moves with the locking tongue 7.

Figure 3 It is a structural schematic diagram of the second working position of the first magnetic attraction member 41 and the rotary clutch connection member. Figure 2 and Figure 3As shown, the seat belt buckle adjustment device also includes a switching mechanism 4; the switching mechanism 4 includes a first magnetic member 41 and a first controller 43; the first magnetic member 41 is axially movably installed on the output shaft 61 of the first driving member 6, and the first magnetic member 41 is provided with a second tooth structure 411, and the second tooth structure 411 cooperates with the first gear 22 or the second tooth structure 411 cooperates with the second gear; the first controller 43 is used to control the first magnetic member 41 to cooperate with the first gear 22 or with the second gear.

[0066] The first magnetic member 41 is moved between a first working position cooperating with the translation clutch connector and a second working position cooperating with the rotation clutch connector by the first controller 43. By controlling the first controller 43, when the first magnetic member cooperates with the translation clutch connector, the lock body 3 can move forward and backward in the X direction.

The power supply of the electromagnetic coil can be turned on by the first controller 43, so that the first magnetic member 41 generates magnetic force, so that the first magnetic member 41 and the second magnetic member 42 attract each other, and the first magnetic member 41 overcomes the elastic force of the elastic member 45 and compresses the elastic member 45, so that when the first magnetic member 41 cooperates with the rotary clutch connector, the lock body 3 can be rotated around the Y axis. When the first controller 43 disconnects the power supply of the electromagnetic coil, the first magnetic element 41 does not generate magnetic force, and moves away from the second magnetic element 42 under the elastic restoring force of the elastic element 45, so that the first magnetic element cooperates with the translation clutch connector to realize the forward and backward movement of the lock body 3X.
