In an embodiment of a third aspect of the invention, there is provided a vehicle comprising: the vehicle cabin and the seat in the embodiment of the second aspect are positioned in the vehicle cabin.
The vehicle according to the embodiment of the invention comprises the adjusting structure according to the embodiment of the invention, and because the adjusting structure according to the embodiment of the invention has the technical effects, the vehicle according to the embodiment of the invention also has the corresponding technical effects that the occupation of the motor assembly on the space behind the adjusting structure is reduced by arranging the motor assembly in front of the base adjacent to the first front connecting bracket, so that more moving space can be provided behind the adjusting structure, and the adjusting angle of the adjusting assembly in the adjusting structure on the supporting framework is increased. For the seat, the increase of the adjustable angle of the supporting framework, namely the increase of the backward adjustable inclination angle of the seat, also realizes the reduction of the foaming step difference between the backrest and the seat cushion when the backrest of the seat rotates backwards, and improves the comfort of the passenger in the seat.
Other structures and operations of the vehicle according to the embodiment of the present invention will be understood and readily implemented by those skilled in the art, and thus will not be described in detail.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
