6, the wing 200 includes a wing 200 support plate and a wing 200 body arranged on the support plate of the wing 200, the support plate of the wing 200 is rotatably mounted on the wing frame 120, the body of the wing 200 is assembled on the support plate of the wing 200, and the connecting components The other end of 330 is fixedly connected with the lower surface of the support plate of the side wing 200 . Specifically, the support piece 333 is fixedly connected to the lower surface of the support plate of the side wing 200, the support piece 333 may be a block structure, and the support piece 333 and the support plate of the side wing 200 may be connected by bolts.

Based on the same inventive concept, the embodiment of the present application also provides a car, which includes the above-mentioned seat. Of course, when passengers get on and off, they will only pass through the side wing 200 close to the door. Therefore, in this embodiment, the driving device 300 is arranged on the side wing 200 of the main driver's seat and the passenger's seat close to the door on the same side. And below the side wings 200 on both sides of the rear seats.

For the convenience of description, in this embodiment, the forward driving direction of the car is defined as "front", and the reverse direction of the car is defined as "rear". Obviously, in this embodiment, the rear end of the side wing 200 is fixed on the frame 120 of the side wing 200 through the rotating shaft, so that the front end of the side wing 200 can swing up and down through the rotating shaft to realize the lifting of the side wing 200 .

In some embodiments, the car includes a door, and the door is provided with a door lock sensor, and the door lock sensor is used to detect the opening and closing of the door. The door lock sensor can be connected with the driving motor signal, so that the lift of the side flap 200 can be determined according to the opening and closing of the door.

In the automobile provided by the embodiment of the present application, when passengers get on and off the vehicle, the driving device 300 drives the side wings 200 to rotate so that the side wings 200 are close to the seat frame 100, thereby lowering the side wings 200, thereby reducing the leg position of the passengers. The uncomfortable feeling during the transition of the seat wing 200 improves the convenience of getting in and out of the passenger.

Based on the same inventive concept, the embodiment of the present application also provides a method for controlling the lift of the side wings of the seat, which is applied to the above-mentioned automobile. Specifically, the method includes:

S1: Determine whether the car is stationary and not powered on;

Since only when the car is stationary and not powered on, the passenger will have the action of getting on/off, so only under the premise that the car is stationary and not powered on, the drive device 300 of the side wing 200 will play a role.

Specifically, when the shift lever is at the "P" position and the ignition switch is at the "LOCK" position, it means that the car is at rest and not powered on.

S2: If the car is stationary and not powered on, determine whether the car door is open;

When the car is stationary and not powered on, it is necessary to further determine whether the door is open. Specifically, the door lock sensor can be used to detect the opening and closing state of the door.

S3: If the vehicle door is opened, the seat side wing is lowered to the lowest; if the vehicle door is closed, the seat side wing is raised to the highest level.

When the passenger is in the situation of getting on the bus, after the passenger opens the door, the seat wing 200 is lowered to the minimum, thereby reducing the discomfort of the legs of the passenger in the process of getting on the car, and when the passenger closes the door, it indicates that the passenger has already boarded the car. , ready to go, whereby the seat wings 200 rise to the highest to provide side support for passengers.

When the passenger is in the situation of getting off the car, after the passenger opens the car door, the seat wing 200 is lowered to the minimum, thereby reducing the discomfort of the legs of the passenger in the process of getting off the car, and when the passenger closes the car door, it shows that the passenger has already got off the car. When leaving the car, the seat wing 200 rises to the highest level, and when the next time the passenger gets on the car and opens the door, the seat wing 200 will be lowered to the lowest level, providing passengers with a sense of getting on the bus.

In some embodiments, when the ignition switch is in the "LOCK" position, if you press and hold the "SET" button for 10 seconds, you can cancel/enable the lifting function of the side wing 200, that is, when the car is stationary and not powered on, No matter the door is opened or closed, the side wing 200 does not rise or fall. When the lift function of the Wing 200 is canceled, the indicator light will flash once, and when the lift function of the Wing 200 is activated, the indicator light will flash twice to remind passengers.

Of course, when the battery is disconnected or the fuse is blown, the side wing 200 lift function cannot be activated. When the battery is connected or the fuse is replaced, and the car is stationary and not powered on, the lift function of the wing 200 can be activated by sending a signal. Specifically, the lift function of the side wing 200 can be activated by opening and closing the driver's door more than twice.

The present application provides a seat, a car, and a method for controlling seat side wing lifting. Since the seat is provided with a driving device 300, the driving device 300 can drive the side wing 200 to rotate relative to the seat frame 100 to adjust the side wing 200 relative to the seat frame. Therefore, when passengers get on and off the bus, the drive device 300 drives the side wings 200 to rotate so that the side wings 200 are close to the seat frame 100, so that the side wings 200 are lowered, thereby reducing the passenger's legs on the side wings of the seat. 200 The discomfort during the transition improves the convenience of getting in and out of the passenger.

While preferred embodiments of the invention have been described, additional changes and modifications to these embodiments can be made by those skilled in the art once the basic inventive concept is appreciated. Therefore, it is intended that the appended claims be construed to cover the preferred embodiment as well as all changes and modifications which fall within the scope of the invention.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
