Problems solved by technology

[0002] In order to further improve the utilization rate of the interior space of the vehicle, the current automobile industry is gradually designing the car seat into a form that can be folded and stored. The car folding seat in the prior art usually adopts an electric drive mechanism on one side of the seat cushion, and the electric drive The mechanism cooperates with the reduction box to drive the seat cushion to rotate automatically, so that the seat cushion can be automatically turned into the storage box; during the rotation process of the electric drive mechanism, before the seat cushion turns to 90°, the electric drive mechanism needs to give the seat cushion a positive traction to drive the seat cushion to rotate, and When the seat cushion is rotated to 90°, it is necessary to give the seat cushion a supporting force in one direction to support the cushion to be slowly folded into the storage box; but often due to the excessive mass of the seat, the electric drive mechanism requires a large output torque, and then the reduction box and The drive motor is relatively large, and it needs to occupy a large layout space of the car body in the actual matching process with the car body. At the same time, the drive components require greater input power, and the energy consumption of the car is relatively large.

Embodiment 1

[0040] see figure 1 and figure 2 A preferred embodiment of the present invention provides a seat auxiliary rotation device, which is used to rotatably connect the seat with the vehicle floor. Spring 5 and rotating plate 6.

[0041] Wherein, the support frame 1 is installed on the vehicle floor, and the support frame 1 has a front plate 11 and a rear plate 12 which are arranged oppositely. The front plate 11 is rotatably mounted on the rear plate 12 at the other end; the gear 4 rotates with the rotating shaft 3, and the rack 2 slides along the first axial direction under the meshing action of the gear 4, and the first axial direction is aligned with the rotating shaft axis vertical.

[0042]Specifically, the rack 2 is perpendicular to the axis of the rotating shaft 3; the rack 2 has a bar body 21 and a slider 22, the bar body 21 is provided with a slideway 211, the top of the bar body 21 is provided with teeth, and the teeth are meshed with the gear 4, A first locking posi...

Embodiment 2

[0070] see Figure 8 , the present invention also provides a seat, including a cushion board and the seat auxiliary rotation device 600 as described in Embodiment 1, one end of the rotating shaft extends out of the support frame, and is connected with the cushion board. The cushion board is arranged on the bottom surface of the cushion.

[0071] Specifically, the seat 700 is mainly composed of a seat cushion, a backrest and a headrest that can be folded or stretched above the backrest. The bottom of the backrest is rotatably connected to the rear end of the seat cushion via a rotary hinge. This swivel hinge allows the backrest to fold over the seat cushion.

[0072] Further, the cushion board 10 is provided with a connecting hole, and one end of the rotating shaft 3 is fixed on the connecting hole.

[0073] Referring to the figure, the electric drive mechanism 800 includes a mounting plate 801, a frame 802 fixed on the mounting plate 801, a bushing installed on the shaft ho...

Abstract

The invention relates to the technical field of automobile seats, and discloses a seat auxiliary rotating device and a seat with the same, the seat auxiliary rotating device is used for rotationally connecting the seat with an automobile bottom plate, the seat auxiliary rotating device comprises a supporting frame, a rack, a rotating shaft, a gear, a torsional spring and a rotating plate, and the rotating shaft is sequentially sleeved with the gear, the torsional spring and the rotating plate; one end of the rotating shaft is rotatably mounted on the front plate, and the other end of the rotating shaft is rotatably mounted on the rear plate; the gear and the rotating plate rotate along with the rotating shaft; in the overturning process of the seat, torque compensation can be carried out on the electric driving mechanism, the output torque of the electric driving mechanism is reduced, the size of the electric driving mechanism is reduced, and the electric driving mechanism has obvious advantages in the aspects of structural size, structural cost and energy loss.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a seat auxiliary rotation device and a seat with the same. Background technique [0002] In order to further improve the utilization rate of the interior space of the vehicle, the current automobile industry is gradually designing the car seat into a form that can be folded and stored. The car folding seat in the prior art usually adopts an electric drive mechanism on one side of the seat cushion, and the electric drive The mechanism cooperates with the reduction box to drive the seat cushion to rotate automatically, so that the seat cushion can be automatically turned into the storage box; during the rotation process of the electric drive mechanism, before the seat cushion turns to 90°, the electric drive mechanism needs to give the seat cushion a positive traction to drive the seat cushion to rotate, and When the seat cushion is rotated to 90°, it is necessary to give the sea...
