[0033] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0034] In view of this, the applicant conducted in-depth research and improvement exploration on vehicle seats and seat belt buckles and found that: with the rapid development of safety technology and the increasing maturity of intelligent driving, the traditional queen driving mode cannot satisfy passengers' better driving experience, and more integrated seats have become the first choice of major domestic and foreign automobile manufacturers.

[0035] Under the premise of satisfying passengers' better comfort, the existing seats' buckle assemblies cannot rotate and move, which easily interferes with the seats, thus reducing the space utilization of the entire vehicle and greatly reducing the comfort experience of passengers. In addition, the existing buckle moving devices have complex structures, use many electronic parts, have low integration, and have single functions, which cannot meet the needs of vehicle platformization and body seats with different travel ranges.

[0036] Based on this, the technical solutions provided by the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0037] The embodiment of this specification proposes an adjustable buckle device, such as Figure 1 and Figure 2 As shown, it includes a buckle 2 and a buckle bracket 3, the buckle bracket 3 is pivotally mounted on the vehicle seat 1 and can move with the vehicle seat 1 between the driving mode and the idle mode, the buckle device also includes a transmission member 4 fixed on the vehicle floor, the transmission member 4 is configured to drive the buckle bracket 3 to rotate to lower the height of the buckle 2 relative to the vehicle floor when the vehicle seat 1 moves from the driving mode to the idle mode.

[0038] Specifically, when designing a vehicle, the transmission member 4 is fixedly mounted on the vehicle floor by screws, the buckle 2 and the tongue on the seat belt can be plugged and locked together, the vehicle seat 1 is in the initial design position, at which time the buckle bracket 3 and the transmission member 4 are not in contact, and the buckle 2 is in a normal installation state. The buckle bracket 3 can be installed in the lower area of ​​the side of the vehicle seat 1. The buckle 2 and the buckle bracket 3 are also covered with a protective cover 6.

[0039] A slide rail 5 is also fixed on the vehicle floor, and the vehicle seat 1 is slidably connected to the slide rail 5 along the length direction of the vehicle body. The space between the vehicle seat 1 and the front part of the vehicle can be adjusted to enable the vehicle to switch between driving mode and idle mode.

[0040] In one embodiment, if Figure 1 and Figure 2 As shown, the buckle bracket 3 is a plate-like structure, and a tooth portion 31 is provided on one side of the buckle bracket 3 close to the transmission member 4. The tooth portion 31 is arranged to protrude outward along the plane where the plate-like structure is located. The transmission member 4 includes a guide bar 43 composed of a plurality of spaced pin-like structures. The tooth portion 31 is embedded in the spaced gaps between the pin-like structures during the movement of the vehicle seat 1, and is supported by the pin-like structures to drive the rotation of the buckle bracket 3. Alternatively, the transmission member 4 includes a rack-like guide bar 43, and the tooth portion 31 and the guide bar 43 are gear-rack meshing transmission.

[0041] Specifically, one end of the buckle bracket 3 is the buckle 2, and the other end is the tooth portion 31. The tooth portion 31 can be composed of a plurality of teeth arranged around the pivot center on the buckle bracket 3. The arrangement length of the teeth around the pivot center can be determined by the rotation range of the buckle bracket 3 and the transmission length of the matching with the guide strip 43. The size of the teeth is adapted to the interval gap between the pin-shaped structures. For example, when the tooth portion 31 moves toward the front of the vehicle with the vehicle seat 1, the tooth structure of the tooth portion 31 gradually engages with the chain structure of the guide. The buckle bracket 3 is provided with a tooth structure, and the integrated design effectively improves the meshing force, while reducing the assembly method, and improving durability and reliability.

[0042] In one embodiment, if Figure 1 and Figure 3 As shown, the transmission member 4 also includes an L-shaped bracket 41 and a guide seat 42; the guide seat 42 includes a mutually perpendicular limit plate and a guide plate; the bottom plate of the L-shaped bracket 41 is fixed to the vehicle bottom plate, the limit plate is fitted and limited on the side plate of the L-shaped bracket 41, and the guide strip 43 is fitted on the top of the guide plate. The bottom plate is detachably set on the vehicle bottom plate through the bottom plate fixing member 44, and the bottom plate fixing member 44 can be a screw. The transmission member 4 and the vehicle body are screwed together, with high integration and easy installation.

[0043] One implementation method of connecting the guide seat 42 with the side plate is that the limit plate is installed on the side plate through the guide fixing member 45. The guide fixing member 45 includes a central columnar structure and clamping plates fixed at both ends of the columnar structure; the columnar structure is penetrated by the limit plate and the side plate, and the clamping plates at both ends clamp and fix the side plate and the limit plate together.

[0044] Another embodiment of the connection between the guide seat 42 and the side plate is that the guide seat 42 can also be arranged to move up and down; a groove structure is formed on the side plate to allow the limit plate to move up and down; a directional column plugged into the directional hole on the guide plate is fixed in the groove structure for directional movement of the guide seat 42 up and down; an elastic member abutting against the bottom of the guide plate is fixed in the groove structure so that the guide plate can move up and down elastically to prevent the tooth portion 31 from moving to the end of the guide bar 43 and getting stuck, and push the guide plate to compress the elastic member to move down so that the tooth portion 31 can be disengaged from the guide bar 43. The elastic member is, for example, a spring. After being disengaged, the buckle bracket 3 can be directly rotated to the initial position of the driving mode.

[0045] In one embodiment, if Figure 2 and Figure 3 As shown, the guide plate is arranged obliquely upward in the direction in which the vehicle seat 1 moves from the driving mode to the idle mode.

[0046] For example, the area of ​​the guide seat 42 corresponding to the idle mode can be horizontally arranged along the length direction of the vehicle body, and the area of ​​the guide seat 42 corresponding to the driving mode can be inclined upward from the direction away from the front part to the front part. The two areas can be smoothly transitioned through an arc. That is, the guide seat 42 and the guide bar 43 are set as a gradual guide track, which has a high degree of integration and can match vehicle seats 1 with different travels and different heights.

[0047] In one embodiment, if Figure 3 As shown, the guide plate is provided with limiting parts for limiting the two sides of the guide strip 43.

[0048] In one embodiment, if Figure 2 and Figure 4 As shown, the teeth 31 are distributed around the pivot center of the buckle bracket 3 on the vehicle seat 1 .

[0049] In one embodiment, if Figure 4 and Figure 5 As shown, the buckle bracket 3 is integrated with a damping component 7, and the buckle bracket 3 is installed on the vehicle seat 1 through the damping component 7. The damping component 7 includes a fastener 71 and a damping spring 72. The fastener 71 passes through the through hole of the buckle bracket 3 and the damping spring 72 in sequence, and the fastener 71 is fixed on the vehicle seat 1. The damping spring 72 supports the buckle bracket 3. The buckle bracket 3 can be pivotally mounted on the vehicle seat 1 through the fastener 71. The buckle bracket 3 can be rotated forward and backward on the vehicle seat 1 through the elastic restoring force of the damping spring 72 to achieve damping self-locking. The damping spring 72 is, for example, a damping spring. The buckle device is provided with a damping spring, which can effectively reduce the shaking amount of the buckle bracket 3 after assembly.

[0050] In one embodiment, if Figure 4 and Figure 5 As shown, the damping component 7 also includes a fixing plate 73 and a clamping member 74. The fastener 71 is clamped and fixed with the clamping member 74. The fixing plate 73 abuts between the end of the damping spring 72 away from the buckle 2 and the clamping member 74 for directional rotation of the buckle bracket 3.

[0051] In one embodiment, if Figure 4 and Figure 7 As shown, a blocking piece and another blocking piece are fixed on the fixing plate 73; one blocking piece can abut against the buckle bracket 3 to limit the position, and the other blocking piece can be inserted and limited with the vehicle seat 1 to limit the rotation range of the buckle bracket 3. The buckle device is provided with a fixing plate 73 and a clamping member 74, which not only plays a directional role, but also the two blocking pieces on the fixing plate 73 can ensure that the buckle 2 can completely return to the designed position when rotating clockwise, thereby improving the design reliability of the product.

[0052] The specific working principle of the embodiment of this specification is as follows: For example, the idle mode can be the queen space mode, that is, Figure 6 The engagement state a of the buckle bracket and the transmission member shown in the figure; the driving mode can be the queen driving mode or the whole vehicle design mode, that is, Figure 6 The buckle bracket and the transmission member are not engaged in the state b shown, that is, Figure 7 The vehicle seat 1 in the queen space mode may be the moving area of ​​the vehicle seat 1 close to the front part of the vehicle, and the seat in the queen driving mode may be the moving area of ​​the vehicle seat 1 away from the front part of the vehicle. The front part of the vehicle may include the steering wheel, the instrument panel and the like. Figure 2 The buckle device of the present application can rotate, which can solve the problems of low experience of traditional queen driving mode, interference between the vehicle seat 1 and the buckle bracket 3 during rotation, and low structural integration of the buckle moving device.

[0053] When the vehicle seat 1 starts the Queen Space Mode, since the vehicle seat 1 is provided with a slide rail 5, the vehicle seat 1 moves as a whole toward the front of the vehicle, and the backrest of the vehicle seat 1 is folded toward the front of the vehicle. When the vehicle seat 1 starts to move forward, the buckle bracket 3 and the transmission member 4 are in a separated state. When the vehicle seat 1 moves forward to a certain distance, the buckle bracket 3 cooperates with the transmission member 4 for transmission, and the toothed structure of the toothed portion 31 gradually engages with the chain structure of the guide member, and the buckle bracket 3 starts to rotate counterclockwise. When the vehicle seat 1 reaches the end of the travel, the top of the buckle 2 is lowered to the lowest point, thereby avoiding contact with the backrest of the vehicle seat 1. For example, the buckle 2 can move from above the seat cushion surface of the vehicle seat 1 to below the seat cushion surface of the vehicle seat 1 following the rotation of the buckle bracket 3.

[0054] When the vehicle seat 1 starts the Queen driving mode, since the vehicle seat 1 is provided with a slide rail 5, the vehicle seat 1 as a whole will move toward the rear of the vehicle, and the seat back will rise toward the rear of the vehicle. When the vehicle seat 1 starts to move backward, the buckle bracket 3 and the transmission member 4 are still in a coordinated transmission state, and the toothed structure of the toothed portion 31 and the chain structure of the guide member are still in meshing, so the buckle bracket 3 starts to rotate clockwise when moving backward. When the vehicle seat 1 moves backward a certain distance, the toothed structure of the toothed portion 31 separates from the chain structure of the guide member, and when the seat reaches the designed driving position, the buckle 2 returns to the designed position.

[0055] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0056] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
