Description
Technical field
The present invention relates to automotive seating art fields, and in particular to rotatable automotive seat when a kind of turning.
Background technology
With the raising that automobile driving speed and people require vehicle safety, comfort level, Automotive designers
Numerous studies energy put into automobile turning navigational challenge, such as to the improvement of the research of seat elasticity and damper, safety belt,
Handrail using etc. increase the comfort level of seating, but for automobile turning, when especially taking a sudden turn, the centrifugal force of generation
Overcome research very few, the centrifugal force that when automobile turning generates can throw away passenger to side, so that passenger is generated sense of discomfort, when serious
It is also possible that some sudden hurt accidents, the seat frame of existing automotive seat are usually fixed together with automobile chassis,
Automotive seat itself can not swing adjustment and offset centrifugal force caused by automobile turning to provide enough centripetal force.
Invention content
In order to solve the above technical problems, the purpose of the present invention is to provide rotatable automotive seats when a kind of turning.
Technical solution is as follows：Rotatable automotive seat, key are when a kind of turning：Including seat frame, in the seat frame
It is hinged with seat, the seat is connected with seat reclining drive device, and the seat frame, which is equipped with, turns to detection device, when described turn
When detecting Vehicular turn to detection device, the seat reclining drive device drives the seat to turn to the homonymy of Vehicular turn
It is dynamic；
The steering detection device includes detection pipe, which is arranged along the left and right directions of the seat, the detection
It is equipped in pipe and rolls bead, detection switch group is equipped in the detection pipe, the rolling bead triggers the detection and opens when rolling
Pass group；
The seat frame includes bottom plate, and face is provided with two pieces of side plates on the bottom plate, and the seat is hinged on two sides
On the bottom plate between plate, the rear portion of two pieces of side plates is connected with backrest frames, and it is bent to be equipped with backrest in the backrest frames
The top of spring, the backrest frames is equipped with head pillow frame.Use detection switch group described in the technical program for pressure sensor or
Close to switch, when Vehicular turn, rolls the centrifugal force that bead is diverted and throw away, to be rolled to one end of detection pipe, work as rolling
Dynamic bead is rolled to detection trigger switching group when in detection switch group, and then triggers seat reclining drive device driving seat and turn
Dynamic, such as when vehicle turns to the left, seat also turns left, and when vehicle turns to the right, seat also turns right, to counteracting portion
Divide the centrifugal force that the when of turning to generates, passenger's body held stationary is made not to be thrown out of.
Preferably, the middle part decurvation of above-mentioned detection pipe forms balance portion, in the detection pipe of the balance portion both sides
It is respectively equipped with the detection switch group, the detection switch group is distributed along the detection pipe length direction.Using this design in vehicle
Rolled when not turning to or under slight jounce condition bead only balance portion roll will not detection trigger switching group, only work as vehicle
Rolling bead, which just will appear, when steering provides sufficiently large centrifugal force substantially rolls to detection trigger switching group, due to balance portion
Both sides are provided with detection switch group along its length, and the angle of Vehicular turn is bigger, and the centrifugal force that rolling bead is subject to is bigger,
It is thrown out of remoter i.e. remoter detection switch group to be triggered, therefore vehicle can determine that according to the position for the detection switch group being triggered
It is to turn to the left or to the right and the size of steering angle.
Above-mentioned detection pipe is embedded to be cased with semi-circular tube, and the outer wall of the semi-circular tube and the inner wall of the detection pipe are adjacent to, the inspection
Slowdown monitoring switch group is arranged on the inner wall of the semi-circular tube.Can detection switch group be first directly installed on semicircle when being installed using this scheme
On the inner wall of pipe, it then will be inserted into detection pipe with the semi-circular tube of detection switch group, greatly facilitate detection switch group
Installation and repair.
It is respectively equipped with switch leads hole on the both ends tube wall of above-mentioned detection pipe.Installation power cord is facilitated using this design.

Wheel is contacted with the lower surface of the seat, and the drive shaft is connected with power plant.Power plant is passed through using this technical solution
Drive shaft turns are driven, to drive the cam at its both ends to rotate simultaneously, when left cam peak is contacted with seat lower surface, and
Seat is in the state i.e. seat of right low left high and has turned right limiting angle when right cam minimum point and seat lower surface contact
On the contrary degree, then seat have turned left extreme angles, during drive shaft drives the cam at both ends to rotate, seat to
Left-hand rotation, which move-returns to equilbrium position-and turns right, to be converted between three kinds of states.
There are two seat bearing, the seat passes through seat for the front-rear direction face setting of seat described in above-mentioned bottom plate upper edge
Shaft is mounted on two seat bearings, and the seat is overturn by described seat shaft or so, the left cam and the right side
Cam is separately positioned on the line both sides of two seat bearings.It is sat by two seat bearings to fix using this programme
Plate forms four supporting points and supports seat, seat installation firm between two seat bearings and two cams.
Above-mentioned power plant includes stepper motor, and the output end of the stepper motor is connected with deceleration mechanism, the deceleration mechanism
Output end and the driving axis connection；
The deceleration mechanism is turbine and worm decelerator, and the wherein output shaft axial restraint of worm screw and stepper motor connects
It connects, the worm and worm wheel engagement, the worm gear is solidly set in the drive shaft.It can be slowed down by worm and gear using this design
And increasing output torque, stepper motor accurately controls the rotational angle of seat.
Above-mentioned detection pipe connects the rear portion of two side plates, the both ends of the detection pipe respectively with the corresponding side
The madial wall of plate connects；
It is respectively equipped with drive shaft hole on two side plates, the both ends of the drive shaft are separately mounted to corresponding described
In drive shaft hole, the side plate around the drive shaft hole forms the driving bearing, and the left cam and right cam lean on respectively
The inner wall of nearly two side plates is arranged.It is arranged at the rear portion of seat using this scheme detection pipe, does not interfere with other component such as
The installation of seat foam, surface cover etc..
Advantageous effect：Advantageous effect using the present invention is that the centrifugal force rolled when Vehicular turn when bead is diverted is got rid of
Go out, to be rolled to detection pipe both ends, detection trigger switching group and then triggering when rolling bead and being rolled in detection switch group
Seat reclining drive device start driving seat rotation, such as when vehicle turns to the left, seat also turns left, when vehicle to the right
Seat also turns right when steering, to offset the centrifugal force generated when part turns to, passenger's body held stationary is made not got rid of
Go out.
