Description
Technical Field
The invention relates to the field of automobile safety, in particular to a safe automobile.
Background
With the rapid development of the automatic driving automobile, the automatic driving automobile will be more in a manual-automatic combination mode in the future, or the automatic-manual automobile can be switched between manual and automatic. The seat can rotate by any angle according to the requirements of a driver, so that the comfortable sensation of people in automatic driving is met. The space arrangement inside the automobile is necessarily changed greatly, and people want to turn around to enjoy scenery outside the window or turn around to talk with other friends and relatives in the automobile and play. On the other hand, the automatic driving technology has a great gap with the expected 'zero accident', and the global case about the automatic driving automobile traffic accident is also rare. Reducing driver injuries through active safety strategies is a good choice when autonomous vehicles face unavoidable collision problems. In an autonomous vehicle, a camera and radar sensor system can predict when the vehicle will collide. In a typical active safety system, the collision warning system may identify an unavoidable collision condition about 0.1-0.35s before a collision occurs. During this time, the driver will be better protected if the driver's seat can be rotated into the proper position.
The defects in the prior seat safety technology are as follows:
1. in the prior art, collision is an unavoidable problem, even if the automobile skill is good, various conditions may be met on the road, and collision cannot be avoided, but the prior art automobile does not protect the personal safety enough.
If the driver's seat is provided with the protective shell, the right hand side of the driver's seat is toward the space which needs more, for example, the control part and the storage box on the right hand side, but the protective shell can obstruct the moving space on the right hand side.
According to the statistics of the automobile safety association, one of the reasons of automobile accidents lies in that when a driver needs to take and place articles on a backseat, the driver can extend forwards with feet subconsciously due to automatic reaction of joints when the driver visits the backseat, and an accelerator is easily triggered, even if the driver is in a parking state at the moment, the driver also easily bombs the accelerator. Thereby causing accidents or reducing the life of the car.
The car seat of prior art, if rotate, just be exactly conventional motor control rotates, can't realize the buffering formula and rotate, and buffering formula rotates the effect that can be fine when being strikeed play the buffering.
The piston driving structure in the prior art needs to reserve the position of a liquid passing hole to ensure that liquid passing is smooth and ensure the reciprocating motion of a piston, and does not have a corresponding structural design for a ring type piston.
If the protective effect of the protective shell and the problem that the protective shell affects the activity space are simultaneously considered in the automobile seat, the two are contradictory, and how to coordinate the problem is difficult.
The automobile seat in the prior art has the advantages that when the buffer type rotating structure is used, the rotation limitation exists inevitably, and the seat cannot rotate in a large range. For example, it is not possible to: the front seat rotates backwards to interact with the rear seat.
The installation belt of the prior art is fixed on the B column, but because the space limitation of the B column, the upper point of the safety belt cannot be adjusted, and the dynamic adjustment safety belt according to the height cannot be realized.
