Description

The motorcar electric back seat

The utility model relates to the seat in a kind of car, particularly relates to a kind of seat of controlling by the motor screw mandrel.

Along with China's constant development of economy, auto-industry are particularly rapid as the main backbone industry development of China's economy, and car has become its main body, and it is quite fast to update.But the exploitation of the existing seat of domestic car relatively lags behind, and particularly back seat all is fixed type basically, can't satisfy because of the integral body upgrading of car the traveling comfort and the class of seat proposed higher requirement.

Be head it off, must exploitation last word---power rear seats, move forward and backward variation with the seat angle by it, satisfy the requirement of passenger's the different bodily forms and various sitting posture to seat.Because the seat cushion and the backrest of original seat directly are fixed on the car shell, can't move, make its motion, just require on the car shell base plate and the skeleton that corresponding two relative positions of design guarantee between the seat cushion, backrest, realize motion by motor-driven, thereby make seat cushion, the backrest movement therewith of fixing on it.

The purpose of this utility model is that a kind of electrically operated car back seat will be provided, and makes a grade on the product specification of back seat, for the complete upgrading of car provides corresponding matching component.

For realizing this purpose, design plan of the present utility model is, on the car shell base plate and between the seat cushion, backrest, design a seat cushion framework and a backrest skeleton, seat cushion framework adopts single motor screw mandrel of settling only placed in the middle to drive down, control motor by the micro-switch on the handrail in the middle of being placed in, move forward and backward together by seat cushion framework on the chute of transmission shift fork drive both sides and the backrest skeleton on the pulley gear, because seat cushion and backrest are fixed on it, make whole seat also move together thereupon.And the both sides chute under the seat cushion framework adopts the camber structure, when making seat mobile, causes that the inclination angle of seat cushion and backrest changes thereon, and the seat angle also changes thereupon, thereby has both guaranteed the motion of seat, can reach the requirement of the maximum traveling comfort of passenger again.Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, compact conformation, novelty, reasonable, easy to operate simple, good stability has promoted the class of auto rear seat, satisfied the requirement of passenger's traveling comfort when taking, the tool promotional value.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model single-piece structural representation;

Fig. 2 is the structural representation of the utility model seat cushion framework assembly and backrest frame assembly.

Among Fig. 1, the utility model mainly is to be made of cushion assembly 1, backrest assembly 2, seat cushion framework assembly 3, backrest frame assembly 4, motor screw mandrel assembly 5, chute assembly 6 and pulley gear assembly 7.

Among Fig. 2, in the motor screw mandrel assembly 5, the feed screw nut 19 of band two ends minor axis 20 is arranged on the motor screw mandrel 18, motor screw mandrel 18 links to each other with motor base 15.Be welded with the stay bearing plate 13 of four curved surface stay bearing plates 9 and two symmetries on the seat cushion framework 29, link by bolt and two secondary chute assemblies 6 on the stay bearing plate 13, the both sides of stay bearing plate 17 placed in the middle respectively are welded with a transmission shift fork 16, and the minor axis 20 of motor screw mandrel 18 snaps in the waist shaped hole of transmission shift fork 16 and carries out transmission; The rear end of seat cushion framework 29 is welded with three tommys 12, is connected the rotation relation when keeping chair motions with three fixing screws 11 of backrest skeleton 30; The rear end of seat cushion framework 29 has two connection hooks 27 of two frame type locationss 21 and leading portion directly to link to each other with cushion assembly 1 in addition, plays location and fixation.

There are two arc stay bearing plates 10 both sides of backrest skeleton 30, and the lower end is welded with three fixing screws 11 and two adapter plates 22, the uniform four blocks of groove plates 26 in top, adapter plate 22 and groove plate 26 directly and backrest assembly 2 connect and fixed and positioning action; Backrest skeleton 30 both sides respectively adorn a permanent seat 23 and pulley gear assembly 7 connects.Pulley base 25 is fixed on the car shell base plate, and a pulley 24 on the device snaps in the waist shaped hole of backrest skeletal fixation seat 23, and when backrest moved with seat cushion, pulley just rotated with the up-and-down movement of permanent seat 23.Wherein, motor screw mandrel 18 links to each other with motor, and motor is electrically connected with micro-switch 8.

Micro-switch 8 of the present utility model, the mode that is designed to be placed on the middle handrail 28 of foldable is controlled motor, and the time spent can be turned down handrail and operate, and the time spent can not close, and both convenient the use do not affect the appearance again.

Motor base 15 can be fixed by bolts on the car shell base plate, and link with motor screw mandrel assembly 5, adopt the nut 19 that has two ends minor axis 20 on single the motor-driven motor screw mandrel of settling 18 placed in the middle, this design goal can be eliminated the shifting time crack, and seat propulsion source and delivery distortion are separated, and guaranteed the electrically operated reliability of seat, and simple in structure, cost-cutting, synchronism also is guaranteed.

In the seat cushion framework assembly 3, adopt the polylith curved surface thin type panel beating stay bearing plate 9 that matches with seat cushion bottom faying face, can alleviate the weight of skeleton like this, reduced the slide relative between skeleton and seat cushion when mobile, guaranteed the stability of seat cushion.In the seat cushion framework 29, also be welded with three block pad skeleton stay bearing plates 17, wherein be distributed in two of both sides and chute assembly and link, both sides placed in the middle are welded with transmission shift fork 16, and the two ends minor axis 20 on the feed screw nut snaps in the waist shaped hole of transmission shift fork.
