Abstract

The utility model discloses a mechanism for regulating an angle of an automobile rear seat backrest. The mechanism consists of an automobile body connection frame, a backrest hanging frame, a drive device and a folding and unfolding mechanism, wherein the automobile body connection frame is fixed with an automobile body; the bottom of the backrest hanging frame is hinged with fixed seats; the fixed seats are fixed on a floor; the folding and unfolding mechanism is connected between the automobile body connection frame and the upper end of the backrest hanging frame; and the drive device drives the folding and unfolding mechanism to work, so that a gap between the automobile body connection frame and the upper end of the backrest hanging frame becomes smaller or bigger, and the inclined angle of the backrest hanging frame becomes bigger or smaller. The regulation mechanism is connected with the automobile body through nuts when used, the seat backrest is connected with the regulation mechanism through nuts after being hung on the regulation mechanism, the inclined angle of the seat backrest can be regulated along with the backrest hanging frame, and the requirement of passengers on comfort is met.

Description

Automobile rear seat backrest angle regulating mechanism

Technical field

The utility model relates to a kind of automobile rear seat, particularly a kind of automobile rear seat backrest angle regulating mechanism.

Background technology

Automotive seat are safety components important on the automobile, in automobile collision procedure, guarantee that seat did not lose efficacy; Not producing has tearing of injury etc. to the occupant, protects the occupant with this, reduces automobile injury to the occupant in collision case; Along with the development of China's automobile industry, auto sale universal day by day, terminal client not only is confined to the requirement to outward appearance; Also begin to pay attention to the comfortableness problem of seat; And comfortableness problem receives increasing concern, and existing automobile rear seat backrest inclination angle can not be adjusted, and unalterable fix with vehicle body and only can't satisfy the requirement of people to traveling comfort with the back seat of turn over function.

Summary of the invention

The purpose of the utility model is to have the problem that automobile rear seat backrest inclination angle can not be adjusted now in order to solve, and a kind of automobile rear seat backrest angle regulating mechanism is provided.

The utility model is by body contact frame, backrest hanger, actuating device and foldingly opens mechanism and constitute that body contact frame and vehicle body are fixed together, and the bottom and the permanent seat of backrest hanger are hinged; Permanent seat is fixed on the floor; Folding open mechanism and be made up of bull stick, first connecting rod, second connecting rod and push rod, actuating device is made up of motor, worm-and-wheel gear, screw rod and movable arm with nut, and the upper end of body contact frame is laterally hinged with bull stick; Bull stick two end inboards are welded with first connecting rod respectively; The head end of two first connecting rods is hinged second connecting rod respectively, and the other end of two second connecting rods is separately fixed at backrest hanger upper end, on the bull stick between two first connecting rods, is welded with push rod; The hinged movable arm in the outer end of push rod with nut; One end of screw rod is connected with the nut of the movable arm with nut, and the other end of screw rod connects with the mouth of worm-and-wheel gear, and the input end of worm-and-wheel gear connects with the mouth of motor; Worm-and-wheel gear is fixed on the body contact frame, and motor and body contact frame are fixed together.

When the utility model uses, regulating mechanism through nut and body contact together, after back of seat was articulated to adjusting mechanism, back of seat passed through nut and is connected with regulating mechanism.

The principle that the utility model is regulated the back of seat angle of inclination is:

Actuating device work spurs push rod downwards, and push rod drives bull stick and turns to the inside downwards, and bull stick drives hinged first connecting rod and second connecting rod is folding, and the upper end of backrest hanger is outward-dipping, and then makes the angle of inclination of back of seat become big.

The actuating device reverse operation, with the push rod ejection that makes progress, push rod drives bull stick and upwards laterally rotates, and bull stick drives hinged first connecting rod and second connecting rod and opens, and the upper end of backrest hanger moves inward, and then the angle of inclination of back of seat is diminished.

The beneficial effect of the utility model is: the utility model makes the angle of inclination of automobile rear seat backrest can regulated at will, has satisfied the requirement of passenger to traveling comfort.

The specific embodiment

See also Fig. 1, Fig. 2 and shown in Figure 3; Present embodiment is by body contact frame 1, backrest hanger 2, actuating device 3 and foldingly opens mechanism 4 and constitute that body contact frame 1 is fixed together with vehicle body, and the bottom of backrest hanger 2 and permanent seat 5 are hinged; Permanent seat 5 is fixed on the floor; Folding open mechanism 4 and be made up of bull stick 41, first connecting rod 42, second connecting rod 43 and push rod 44, actuating device 3 is made up of motor 31, worm-and-wheel gear 32, screw rod 33 and movable arm 34 with nut, and the upper end of body contact frame 1 is laterally hinged with bull stick 41; Bull stick 41 2 end inboards are welded with first connecting rod 42 respectively; The head end of two first connecting rods 42 other end of 43, two second connecting rods 43 of hinged second connecting rod respectively is separately fixed at backrest hanger 2 upper ends, on the bull stick between two first connecting rods 41 41, is welded with push rod 44; The hinged movable arm 34 in the outer end of push rod 44 with nut; One end of screw rod 33 is connected with the nut of the movable arm with nut 34, and the other end of screw rod 33 connects with the mouth of worm-and-wheel gear 32, and the input end of worm-and-wheel gear 32 connects with the mouth of motor 31; Worm-and-wheel gear 32 is fixed on the body contact frame 1, and motor 31 is fixed together with body contact frame 1.

When the utility model used, regulating mechanism assembly and vehicle body linked together through nut, and after back of seat A was articulated to adjusting mechanism, back of seat A was connected with regulating mechanism through nut.

Actuating device 3 work; Push rod 44 is spurred downwards, and push rod 44 drives bull stick 41 and turns to the inside downwards, and it is folding with second connecting rod 43 that bull stick 41 drives hinged first connecting rod 42; The upper end of backrest hanger 2 is outward-dipping, and then makes the angle of inclination of back of seat A become big.

Actuating device 3 reverse operations; With push rod 44 upwards ejections, push rod 44 drives bull stick 41 and upwards laterally rotates, and bull stick 41 drives hinged first connecting rod 42 and opens with second connecting rod 43; The upper end of backrest hanger 2 moves inward, and then the angle of inclination of back of seat A is diminished.
