Abstract
In a seat moving apparatus, a gear mechanism includes a first gear and a second gear that are connected in a transmission manner. A first moving apparatus is connected to a base and a first rack, and the first rack is engaged with the first gear. A second rack is connected to a seat body, and the second rack is engaged with the second gear. A locking apparatus is connected to both the base and the seat body, and the locking apparatus prevents the seat body from moving toward a vehicle rear in a locked state. During a collision or impending collision, it increases driver-vehicle front distance to avoid injury.
Claims20
A seat moving apparatus, comprising:
- a base configured to connect to a vehicle body;
- a gear mechanism, comprising a first gear and a second gear that are connected in a transmission manner, wherein both the first gear and the second gear are rotatably connected to the base;
- a first rack engaged with the first gear;
- a second rack engaged with the second gear and configured to connect to a seat body, wherein both a first length direction of the first rack and a second length direction of the second rack are configured to be parallel to a longitudinal direction of the vehicle body;
- a first moving apparatus connected to the base and the first rack and configured to drive the first rack to move in the first length direction to enable the seat body to move in the longitudinal direction;
- and
- a locking apparatus connected to the base and configured to:
- connect to the seat body;
- and
- prevent the seat body from moving in a locked state,
- wherein the gear mechanism is configured to enable a moving speed of the second rack to be greater than a moving speed of the first rack.
A seat body control method comprising:
- obtaining travel data of a vehicle;
- analyzing the travel data to obtain a collision determining result;
- and
- controlling, when the collision determining result is positive, a seat body of the vehicle to move toward a rear of the vehicle.
A vehicle seat, comprising:
- a seat body;
- and
- a seat moving apparatus connected to the seat body and comprising:
- a base configured to connect to a vehicle body;
- a gear mechanism comprising a first gear and a second gear that are connected in a transmission manner, wherein both the first gear and the second gear are rotatably connected to the base;
- a first rack engaged with the first gear;
- a second rack engaged with the second gear,
- wherein both a first length direction of the first rack and a second length direction of the second rack are parallel to a longitudinal direction of the vehicle body,
- a first moving apparatus connected to the base and the first rack and configured to drive the first rack to move in the first length direction to enable the seat body to move in the longitudinal direction;
- and
- a locking apparatus connected to the base and configured to prevent the seat body from moving in a locked state,
- wherein the gear mechanism is configured to enable a moving speed of the second rack to be greater than a moving speed of the first rack.
