Description

Technical Field

[0001] The present invention relates to the technical field of vehicle manufacturing, and particularly to a seat bracket and a vehicle. Background Art

[0002] The safety and comfort of automotive seats are important evaluation indicators for seat design. Due to different body shapes, drivers and passengers often adjust the seat position according to their needs. Automotive seats are all installed on the slide rails through seat brackets, and the seat brackets and slide rail brackets cooperate with each other to complete the adjustment of the seat position.

[0003] During automotive seat collision tests and in the event of a car accident, due to the effect of inertia, the automotive seat will move forward or backward along the extension direction of the guide rail. To ensure the safety of the driver and passengers, it is generally necessary to set collision stop points on the seat bracket to limit the deformation of the seat and the displacement of the occupants during the collision. However, the collision stop points of the seats in the related art can only provide a stop point function for collisions in a specific direction at a specific position of the seat. This will result in no collision stop point limit when the seat is in other positions and in collisions in other directions, and there will be risks of seat failure and occupant safety. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an embodiment of the present invention provides a seat bracket that can achieve locking under different impact conditions.

[0005] An embodiment of the present invention also provides a vehicle having the above seat bracket.

[0006] The seat bracket of the embodiment of the present invention includes a bracket body, a first swing arm, and a second swing arm. The bracket body is provided with a first hinge point and a plurality of first limiting parts.

[0030] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0031] As Figures 1-5 shown, the seat bracket of the embodiment of the present invention includes a bracket body 1, a first swing arm 2 and a second swing arm 3. Among them, the bracket body 1 is generally connected to the slide rail 7 inside the vehicle, and the bracket body 1 can drive the seat to move in the front-back direction of the vehicle. The first swing arm 2 is connected to the seat, and the first swing arm 2 can swing relative to the bracket body 1 to drive the seat to rise or fall.

[0032] Among them, a first hinge point 17 and a plurality of first limiting parts are provided on the bracket body 1. One end of the first swing arm 2 is hinged to the first hinge point 17, so that the first swing arm 2 can swing around the first hinge point 17. A second hinge point 21 is provided on the first swing arm 2, and the first hinge point 17 and the second hinge point 21 are not concentric. One end of the second swing arm 3 is hinged to the second hinge point 21.

[0033] In the normal driving state of the vehicle, the first swing arm 2 and the second swing arm 3 are relatively fixed. When the first swing arm 2 rotates to drive the seat to rise and fall, it can drive the second swing arm 3 to swing, and the track of the second swing arm 3 is an arc. The first limiting part is adjacent to and does not coincide with the arc track 8 of the swing of the second swing arm 3.

[0034] A second limiting part 4 is provided at the second end of the second swing arm 3. The second limiting part 4 can slide on the bracket body 1 along the arc track 8 with the second swing arm 3. The second swing arm 3 can also swing around the second hinge point 21. When the second swing arm 3 swings around the second hinge point 21 to a preset position, the second limiting part 4 is aligned with the first limiting part, and the second limiting part 4 can cooperate with the first limiting part. At this time, both the first swing arm 2 and the second swing arm 3 are locked, and neither of them can swing or move relative to the bracket body 1.

[0035] When the vehicle is running normally, the seat can be freely adjusted in height under the drive of the first swing arm 2, and the seat adjustment is not affected. When the vehicle collides, under the action of inertia, the second swing arm 3 will swing forward or backward and drive the second limiting part 4 to cooperate with the first limiting part to lock the seat, thereby ensuring the safety of the driver and passengers.

[0036] It should be noted that the seat in the related art can only be locked when colliding in a specific direction at a specific position, while the seat bracket of the embodiment of the present invention has a simple structure. By increasing the number of the first limiting parts and adjusting the positions of the first limiting parts, the seat can be locked under impacts at different heights and in different directions, greatly improving the safety of the vehicle and the protection ability for the driver and passengers.

[0037] In some embodiments, the first swing arm 2 is swingable between at least two positions. In other words, the seat can be adjusted between at least two different height positions, thereby ensuring the comfort of the driver and passengers. And when the first swing arm 2 swings to any position, the second swing arm 3 can swing around the second hinge point 21 and drive the second limiting part 4 to cooperate with the first limiting part.

[0038] When the first swing arm 2 is in any position, at least two first limiting parts are correspondingly arranged to ensure that the second limiting part 4 can cooperate with the first limiting part to lock the seat whether the vehicle collides forward or backward.

[0039] Specifically, as Figures 3-5 shown, the bracket body 1 is swingable between a first adjustment position, a second adjustment position and a third adjustment position. The inclination angle of the first swing arm at the first adjustment position is smaller than the inclination angle of the first swing arm at the second adjustment position, and the inclination angle of the first swing arm at the second adjustment position is smaller than the inclination angle of the first swing arm at the third adjustment position.

[0040] In other words, the inclination angle of the first swing arm increases successively at the first adjustment position, the second adjustment position and the third adjustment position. When the first swing arm is at the first adjustment position, the seat is at the lowest height. When the first swing arm is at the second adjustment position, the seat is at the middle height. When the first swing arm is at the third adjustment position, the seat is at the highest height. Of course, the seat height adjustment is not limited to the above three heights and can be increased or decreased according to different vehicle models.

[0041] Further, as Figure 2 shown, the multiple first limiting parts include a first limiting hole 11, a second limiting hole 12, a third limiting hole 13, a fourth limiting hole 14, a fifth limiting hole 15 and a sixth limiting hole 16.

[0042] When the first swing arm 2 moves to the first adjustment position, the position of the second hinge point 21 changes. Both the first limiting hole 11 and the second limiting hole 12 are located on a circle centered at the second hinge point 21 with the length of the second swing arm as the radius. When a forward collision occurs to the vehicle, the second swing arm 3 swings forward and engages into the first limiting hole 11. When a rearward collision occurs to the vehicle, the second swing arm 3 swings backward and engages into the second limiting hole 12. The first limiting hole 11 and the second limiting hole 12 are respectively arranged on both sides of the arc-shaped track 8.

[0043] Similarly, when the first swing arm 2 moves to the second adjustment position, the position of the second hinge point 21 changes. Both the third limiting hole 13 and the fourth limiting hole 14 are located on a circle centered at the second hinge point 21 with the length of the second swing arm as the radius. When a forward collision occurs to the vehicle, the second swing arm 3 swings forward and engages into the third limiting hole 13. When a rearward collision occurs to the vehicle, the second swing arm 3 swings backward and engages into the fourth limiting hole 14. The third limiting hole 13 and the fourth limiting hole 14 are respectively arranged on both sides of the arc-shaped track 8.

[0044] When the first swing arm 2 moves to the third adjustment position, the position of the second hinge point 21 changes. Both the fifth limiting hole 15 and the sixth limiting hole 16 are located on a circle centered at the second hinge point 21 with the length of the second swing arm as the radius. When a forward collision occurs to the vehicle, the second swing arm 3 swings forward and engages into the fifth limiting hole 15. When a rearward collision occurs to the vehicle, the second swing arm 3 swings backward and engages into the sixth limiting hole 16. The fifth limiting hole 15 and the sixth limiting hole 16 are respectively arranged on both sides of the arc-shaped track 8.

[0045] The first limiting hole 11, the third limiting hole 13 and the fifth limiting hole 15 are located on the same side of the arc-shaped track 8. The first limiting hole 11, the third limiting hole 13 and the fifth limiting hole 15 are arranged at intervals in sequence along the extension direction of the arc parallel to the arc-shaped track 8. The second limiting hole 12, the fourth limiting hole 14 and the sixth limiting hole 16 are located on the same side of the arc-shaped track 8. The second limiting hole 12, the fourth limiting hole 14 and the sixth limiting hole 16 are arranged at intervals in sequence along the extension direction of the arc parallel to the arc-shaped track 8.

[0046] As Figure 1 and Figure 3 shown, in some embodiments, the seat bracket further includes a first elastic member 5 and a second elastic member 6. Optionally, both the first elastic member 5 and the second elastic member 6 are springs. The first elastic member 5 and the second elastic member 6 are respectively arranged on both sides of the second swing arm 3. The first end of the first elastic member 5 and the first end of the second elastic member 6 are both connected to the second swing arm 3. The second end of the first elastic member 5 and the second end of the second elastic member 6 are both connected to the first swing arm 2.

[0047] The interaction between the first elastic member 5 and the second elastic member 6 enables the second swing arm 3 to always maintain a balanced state during normal driving of the vehicle. The first swing arm 2 can drive the second swing arm 3 to swing along the arc track 8. When the vehicle collides, one of the first elastic member 5 and the second elastic member 6 contracts and the other elongates, and the second swing arm 3 swings around the second hinge point 21 to drive the second limiting portion 4 to snap into the limiting hole.

[0048] A connecting seat 31 is provided on the second swing arm 3. The connecting seat 31 is located on the side of the second swing arm 3 adjacent to the first swing arm 2. A first connecting ear 32 and a second connecting ear 33 are provided on the first swing arm 2. The first ends of the first elastic member 5 and the second elastic member 6 are both connected to the connecting seat 31. The second end of the first elastic member 5 is connected to the first connecting ear 32, and the second end of the second elastic member 6 is connected to the second connecting ear 33. In the normal state of the vehicle, the length directions of the first elastic member 5 and the second elastic member 6 are both perpendicular to the length direction of the second swing arm.

[0049] In some embodiments, the second limiting portion 4 is a spring pin. One end of the spring pin is telescopic and is provided with a spring. When the vehicle does not collide, one end of the spring pin abuts against the bracket body 1 and slides on the surface of the bracket body 1. When the vehicle collides, the second swing arm 3 drives the spring pin to move to the limiting hole. Under the action of the spring, one end of the spring pin pops out and snaps into the limiting hole to achieve locking.

[0050] The vehicle according to the second aspect embodiment of the present invention includes a slide rail 7, a seat body (not shown), and the seat bracket described in any of the above embodiments. The slide rail 7 is installed inside the vehicle body along the front-back direction of the vehicle body. The bracket body 1 is slidably installed on the slide rail 7. The seat body is connected to the first swing arm, and the swing of the first swing arm can drive the seat body to adjust the height.

[0051] For the vehicle according to the embodiment of the present invention, when the seat is at different heights, locking can be achieved for impacts in any direction, the safety factor of the vehicle is high, and the protection ability for the driver and passengers is strong.
