Description

Automobile seat framework for multi-scene application Technical Field The invention relates to the technical field of automobile seats, in particular to an automobile seat framework for multi-scene application. Background Along with the continuous promotion of the intelligent and electric level of car, the multi-functional utilization of vehicle inner space gradually becomes the important development direction in the passenger car design, especially in the motorcycle type of multirow seat overall arrangement, and the functional demand of third row seat under scene such as taking, accomodating and emergent use is diversified increasingly. The existing automobile seat framework mostly uses a single use scene as a design target, and usually only supports the backrest angle adjustment or the whole overturning function, the structural form and the driving mode of the existing automobile seat framework are relatively fixed, and flexible switching between different use scenes is difficult. In the prior art, the headrest of the third row of seats is usually manually adjusted, the adjusting gear is limited, the headrest is difficult to continuously adjust according to different heights and using states of passengers, and in the overturning or storage process of the seats, the headrest is often required to be manually adjusted to a specific position, so that the operation steps are more, and the use is inconvenient. Meanwhile, although part of the seat framework has an electric backrest adjusting function, under the condition that the whole vehicle is powered off due to collision of the vehicle, the electric driving mechanism cannot work, the backrest is difficult to release rapidly, and passengers are influenced to escape through the direction of the trunk. In addition, in the current multirow seat under the line Li Zhuangzai scene, only support the single mode that the back overturned or the cushion wholly overturned generally, common structure is mostly cushion integral or the back components of a whole that can function independently, the integral integrated form of cushion, when needs one side seat keeps taking, the opposite side is taken in the upset, and space utilization mode is limited, is difficult to consider taking with the multiple demand of luggage storage. Meanwhile, before the overturning of the part of the whole overturning type seat is finished, a plurality of operation steps such as headrest downward adjustment, backrest unlocking, cushion overturning and the like are needed to be finished manually and sequentially, the operation flow is complex, and the convenience is not enough. In some specific use scenes, such as long-time parking, outdoor leisure or emergency, the existing seat framework structure has limited linkage control capability on the headrest, the backrest and the cushion, and multi-component cooperative action is difficult to realize, so that the application capability of the seat in multiple scenes is limited. Disclosure of Invention According to the automobile seat framework for multi-scene application, the technical problems that the existing seat framework is insufficient in multi-scene switching capability, complex in operation flow, limited in space utilization flexibility and the like are solved by means of structural cooperation and driving cooperation among all parts of the seat framework through the automobile seat framework capable of being applied to the multi-scene application. The invention provides an automobile seat framework for multi-scene application, which comprises a backrest framework and a cushion framework hinged with the backrest framework, a headrest assembly arranged on the upper part of the backrest framework, a backrest adjusting mechanism arranged on the backrest framework and used for driving the backrest framework to vertically move, and a turnover driving mechanism arranged on the cushion framework and used for driving the cushion framework to perform turnover motion relative to a vehicle body, wherein the headrest assembly is provided with a headrest supporting element connected with the backrest framework and a headrest driving element used for driving the headrest supporting element to vertically move, the backrest adjusting mechanism is arranged on the backrest framework and used for driving the backrest framework to perform angle adjustment relative to the cushion framework, the backrest adjusting mechanism is simultaneously provided with an electric adjusting state and a manual unlocking state, and a ground lock assembly is arranged on the cushion framework and used for locking the cushion framework on a vehicle body floor, and the backrest framework and the cushion framework on at least one side can be independently turned relative to the cushion framework on the other side under the unlocking state. Preferably, the headrest support element is provided with a support framework capable of sliding longitudinally under the drive of the headrest dr
