Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a zero-gravity mechanism. Background Art

[0002] Car seats are important components inside a car and can be roughly divided into independent seats and long-row seats depending on the type of car. Specifically, car seats are mainly composed of seat frames, foam, fabrics and adjustment mechanisms. Among them, the seat frame is the foundation of the entire seat, which supports all other components and ensures the stability and safety of the seat. The foam provides softness and comfort to the seat, allowing passengers to feel good support and cushioning during the ride. The fabric covers the foam and frame, which not only plays a decorative role, but also affects the breathability and wear resistance of the seat. The adjustment mechanism allows passengers to adjust the seat angle, height and front and rear position according to their body shape and preferences to achieve the best riding experience.

[0003] Existing car seats can only be adjusted to move diagonally forward, backward, up and down. However, the seat surface inclination angle is fixed, which causes passengers with different leg lengths to feel uncomfortable when riding. Therefore, a zero-gravity mechanism is proposed to solve the above problem. Utility Model Content

[0004] The utility model provides a zero-gravity mechanism, which solves the above technical problems.

[0005] To solve the above technical problems, the utility model provides a zero gravity mechanism, including a seat frame, a rotating shaft rotatably connected in the middle of the seat frame, a seat mounting leg fixed on the surface of the rotating shaft, a driving motor is arranged inside the seat frame, a linkage shaft is transmission-connected on the surface of the driving motor, an angle adjuster is fixed at both ends of the linkage shaft, a connecting bracket is transmission-connected on the surface of the angle adjuster, a transmission bracket is fixed on the surface of the connecting bracket, a linkage plate is rotatably connected to the other end of the transmission bracket relative to the connecting bracket, a positioning column is fixedly connected to the seat frame, and the other end of the connecting bracket relative to the angle adjuster is rotatably connected to the seat mounting leg.

[0006] Preferably, a mounting hole is provided on the surface of the seat mounting leg and the mounting hole is fixed inside the vehicle body by bolts.

[0007] Preferably, the surfaces of the angle adjusters fixed at both ends of the linkage shaft are provided with transmission brackets and connecting brackets, and the transmission brackets and connecting brackets are connected in the same manner as the linkage plate and the seat mounting legs.

[0008] Compared with the related art, the zero gravity mechanism provided by the utility model has the following beneficial effects:

[0009] The utility model drives the connecting bracket and the transmission bracket to rotate through a driving motor. The connecting bracket and the transmission bracket act as hinges between the positioning column and the seat installation leg, so as to lift up one side of the seat frame and adjust the seat angle. The front and rear inclination angles of the seat can be effectively changed to adapt to passengers with different leg lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Example, by Figure 1-4 It is given that the utility model includes a zero gravity mechanism, including a seat frame 8, a rotating shaft 7 is rotatably connected in the middle of the seat frame 8, a seat mounting leg 1 is fixed on the surface of the rotating shaft 7, a driving motor 6 is arranged inside the seat frame 8, a linkage shaft 10 is transmission-connected on the surface of the driving motor 6, an angle adjuster 5 is fixed at both ends of the linkage shaft 10, a connecting bracket 4 is transmission-connected on the surface of the connecting bracket 4, a transmission bracket 3 is fixed on the surface of the connecting bracket 4, the transmission bracket 3 is rotatably connected to a linkage plate 2 relative to the other end of the connecting bracket 4, the linkage plate 2 is fixedly connected to a positioning column 9 relative to the other end of the transmission bracket 3, the positioning column 9 is fixedly connected to the seat frame 8, and the connecting bracket 4 is rotatably connected to the seat mounting leg 1 relative to the other end of the recliner 5.

[0016] The surface of the seat mounting leg 1 is provided with a mounting hole and the mounting hole is fixed inside the vehicle body by bolts.

[0017] The surfaces of the angle adjusters 5 fixed at both ends of the linkage shaft 10 are provided with transmission brackets 3 and connecting brackets 4, and the transmission brackets 3 and connecting brackets 4 are connected in the same manner as the linkage plate 2 and the seat mounting leg 1.

[0018] The seat mounting leg 1 is fixed to the inside of the vehicle body by bolts. When the seat angle needs to be adjusted, the power supply of the drive motor 6 is connected. The drive motor 6 drives the angle adjuster 5 to rotate through the linkage shaft 10, and the angle adjuster 5 drives the connecting bracket 4 to rotate. Since the connecting bracket 4 and the transmission bracket 3 are fixedly connected, the connecting bracket 4 rotates. Since the connecting bracket 4 is rotationally connected relative to the seat mounting leg 1 and the seat mounting leg 1 is fixed, the connecting bracket 4 drives the connecting bracket 4 itself and the transmission bracket 3 to move up and down when the connecting bracket 4 rotates, and the angle between the transmission bracket 3 and the linkage plate 2 changes. Since the linkage plate 2 is fixedly connected to the positioning column 9, the linkage plate 2 lifts the positioning column 9, and the seat frame 8 rotates relative to the rotating shaft 7 at this time to change the angle of the seat.
