Description

Automatic mechanism for vehicle door

The utility model relates to the car door folding automatic machine of motor vehicles, refers to the car door automatic machine of large and medium-sized passenger vehicle especially.

In the background technology of the present utility model, what the car door of car had connects with vehicle body with the hinge assembling form, makes car door do arc rotation carrying out folding under manual case.What have also will have chute on the vehicle body, make on the car door lower edge chute make the push-and-pull rectilinear motion and carry out folding.The folding of these two kinds of car doors all needs the people to award certain slide force could realize that weak point is: effort, time-consuming when opening the door, and also inconvenient, not tight because of closing the door sometimes at closing time, cause easily that some unnecessary accident takes place from opening car door in the vehicle '.

The purpose of this utility model is: in order to make Motor vehicle door to modernization development, solving car door can open the door and close the door automatically, also has the function that opens Door by Hand and close the door concurrently simultaneously, make the user can be safer, get on the bus more easily and get off.

Technical solution of the present utility model is as follows:

The relay J 1 and the J2 of the 1 rotating work of control motor, cam 3 control relay J1 and J2 action by camshaft 21, motor 1 output shaft is passed to shaft gear 5 through deceleration device 2 with power, its special character is, pinion 7 engagements of assembling on shaft gear 5 outputs and the little axle 6, on the reel 14 with the bearing supporting on the support 15, assemble three little axles 6, three uniform pinions 7 mesh with ring gear 8 internal tooths, ring gear 8 external tooths and tooth bar 10 leave or engagement fit, the manual lock shaft 9 of assembling cooperates with plane on the tooth bar 10 in the support 15, under the overload condition, tooth bar 10 parallel moving, move and control motor 1 rotating through touching linked switch K, assemble tooth bar 10 moving up and down and guide block 11 in the support 15 on the axostylus axostyle 13, spring 12, reel 14 outputs connect fork 17 through centering block 16, hinged fork 17 and 18 and connecting rod 23 on the sliding pin 22, the hinged slide-bar 19 of fork 18 other ends, angle fork 20 on the groove assembling camshaft 21 on the fork 18, adjusting screw 24 1 client link connecting rods 23, the other end connects car door 26 through hinge seat 25.

Description of drawings of the present utility model is as follows:

Fig. 1 is an overall structure work schematic diagram.

Fig. 2 be among Fig. 1 A to view.

Fig. 3 is a B-B sectional view among Fig. 2.

Fig. 4 be among Fig. 1 C to view.

Number in the figure is described as follows:

The 1-motor, 2-deceleration device, 3-cam, 4-circuit control device, 5-shaft gear, the little axle of 6-, 7-pinion, 8-ring gear, 9-lock shaft, 10-tooth bar, the 11-guide block, 12-spring, 13-axostylus axostyle, 14-reel, 15-support, the 16-centering block, 17-fork, 18-fork, 19-slide-bar, 20-angle fork, the 21-camshaft, 22-sliding pin, 23-connecting rod, 24-adjusting screw, the 25-hinge seat, 26-car door, 27-car body, 28-car door lamp control line.

Be that the utility model adjoint is described in further detail below:

Referring to each figure, in large and medium bus, on the car body 27 of car door 26 1 sides, assembling the utility model, in support 15, assembling motor 1, deceleration device 2, circuit control device 4 and executing agency, wherein deceleration device 2 is made up of commercially available packaged reducer and reversing arrangement, in the circuit control device 4, relay J 1 in parallel is connected motor 1 with the J2 output, it is extreme that its input connects the automobile power source plus or minus, and the control line 28 of car door lamp rotates control with the action control of relay J 1, J2 by the cam on the wheel shaft 21 3.Motor 1 is through deceleration device, three pinions, 7 engagements on the little axle 6 of its output shaft gear 5 and three, three little axles 6 all are assemblied on the reel 14, pinion 7 and the engagement of ring gear 8 internal tooths, ring gear 8 external tooths and tooth bar 10 mesh or leave, and tooth bar 10 two ends are assembled spring 12, guide block 11 respectively; Guide block 11 1 skew back faces cooperate up and down with tooth bar 10 both ends of the surface, control tooth bar lock shaft 9 section semicirculars in shape up and down, when rotation lock shaft 9 changes about 180 °, disc compressing tooth bar 10 is downward, when changeing 180 ° again, lock shaft 9 leaves tooth bar 10, and tooth bar 10 moves under car door 26 overload condition voluntarily to the left or to the right, makes the K outage.

Whole operating principle is like this: when manual driving lever is removed to automatic run location; be that the prominent face of lock shaft 9 circles leaves tooth bar 10; this moment, limit for tonnage was protected and automatic conversion work; if car door is closed condition at this moment; when need are driven door 26; press button; relay J 2 actions; motor 1 forward or reverse; shaft gear 5 is driven by deceleration device; driving three pinions 7 rotates; pinion 7 drives ring gear 8 to be desired to rotate together; but ring gear 8 and tooth bar 10 were engaged with each other and were braked this moment; so pinion 7 drives reel 14 one by little axle 6 and does the planet operation; reel 14 outputs and centering block 16 are fixedly connected; centering block 16 rotates thereupon; and drive fork 17 swings, because of fork 16; 17 and connecting rod 23 be slidingly connected, so when fork 17 rotates; fork 16 and connecting rod 23 are all done compound gyration around slide-bar 19; adjusting screw 24 and connecting rod 23 thread connection, and connects with car door 26 by hinge seat 25 are done when connecting rod 23 and to be turned round when moving; pulling car door 26; the car door interior wing is restricted by inner hinge and slide rail, can only turn back along the guide rail orientation with interior wing, so far car door opening.In like manner, press button and make relay J 1 action, motor 1 reverses or is just changeing, and car door is closed voluntarily and resetted.

When door contact interrupter, because the revolution of fork 18 drives angle fork 20 rotary oscillations that cooperate by guide groove, the camshaft 21 of connection is rotated thereupon, cam 3 control relay J1 or J2 action realize closing the door or opening the door, and the while also can be controlled 28 conductings of car door lamp control line or close.

Overload protection of the present utility model is achieved in that in service automatically; because ring gear 8 and tooth bar 10 engagements; when reel 14 surpasses limit for tonnage; tooth bar 10 is made a direction straight line and is moved, and touches the linked switch 4 in the circuit control device 4, makes motor 1 stop just to change; counter-rotating simultaneously; so the car door of just opening returns again again because of overload, in like manner, the car door of just closing also can be opened by phase down voluntarily because of overload.

When the needs car door with opening Door by Hand or at closing time, stir lock shaft 9 and forward the room to, under spring 12 and guide block 11 effects, make tooth bar 10 up, break away from engagement, at this moment, hand switch door, reel 14 rotate thereupon, drive the pinion 7 on little axle 6 and the little axle 6, the ring gear 8 of engagement is done loose running.

Advantage of the present utility model and effect are:

1, with load limit protective device, automatic transfer equipment and planetary reducer with simple version, be assembled into cleverly one, realize the car door automatic shutter, through test, stable work in work, highly sensitive, respond well.

2, automatic shutter car door does not affect the service behaviour of former manual switching car door.

3, make sense of the times big, that microbus has higher operating efficiency and advanced person, the more sense of security and convenient sense are arranged to the motroist.

4, behind the closing of the door, can lock door, make human pilot more convenient.
