Abstract

The utility model relates to an automatic opening and closing device for a car door. The main structure is that a scroll bar, a turbine and a drive gear are driven to rotate by a miniature DC motor arranged in the cavity of a car door, and a rack bar is driven to move horizontally by the drive gear. With the horizontal movement of the rack bar, a switch lock mechanism comprising a rotor wheel, an arc draw rod and a connecting rod and an opening and closing mechanism comprising a switch control board and a push rod are driven to work, so the self-closing of the car-door lock and the automatic switch of the car door are realized. The utility model is characterized in that the opening and closing of each car door of the car can be operated by a driver conveniently, and the utility model can avoid the traffic accident caused by that other passengers open and close the car door.

Description

The sedan door recloser

The utility model is a kind of recloser of sedan door.

At present, China's car industry development is very fast, social demand amount cumulative year after year, and the class of car is also progressively improving.But the car door of existing car but is a hand switch always, often needs the people who is sitting near the car door position manually to operate when the Kai Heguan car door, promptly often needs passenger's switch voluntarily for the car door away from the driver present position.When the passenger is not yet done to vehicle condition, can make troubles to it, particularly for the not strong passenger of traffic safety consciousness, also can cause traffic accident sometimes because of switch car door voluntarily.

In view of the foregoing, the purpose of this utility model provides a kind of easy to operate and help the sedan door recloser of traffic safety.

The purpose of this utility model is achieved in that it comprises locking bar that places the car door inner chamber and the door-hinge that car door is rotated, it is characterized in that: in the inner chamber of car door, be provided with DC micromotor, the scroll bar that this motor shaft connected is meshed with turbine, and with the coaxial travelling gear of turbine and can being meshed along the ratch that moves horizontally, the vertical rod top that is one with this ratch is provided with by moving runner, the switch lock mechanism that the control locking bar that arc pull bar and connecting rod constitute is flexible, on vertical rod, also be fixed with the door contact interrupter control panel that moves horizontally and have slide opening with it, place this control panel hinged with slide bar and push rod one end in the slide opening, the other end of push rod and place the location on the car body to take out hinged.Drive scroll bar, turbine rotation by DC micromotor, and move horizontally by travelling gear drive ratch.Move horizontally in the process at ratch, flexible by switch lock mechanism controls locking bar reaches the purpose of switch lock with this, by the switch control panel, and the opening or closing of control car doors such as push rod.

In order to break down in automatic opening and closing door mechanism, can adopt the hand switch car door, an electromagnet can be set in the car door inner chamber, the other end of the driving lever that this electromagnet is controlled places on the travelling gear shift fork that is located on a positioning rod, on this backstay, also be provided with the back-moving spring that the travelling gear shift fork is resetted, promptly hold an end of driving lever by electromagnet, the other end drive travelling gear shift fork of driving lever is moved, travelling gear and ratch are separated from, just can implement the hand switch car door this moment, behind the electromagnet deenergization, travelling gear is pushed back the position that originally is meshed with ratch by back-moving spring.

The utility model has the advantages that: the switch of each car door of car all can both make things convenient for the passenger by driver's one man operation, can try to forestall traffic accidents again.

Below in conjunction with accompanying drawing the utility model is explained.

Accompanying drawing is a structural representation of the present utility model.

By accompanying drawing as can be known, the scroll bar 3 that places DC micromotor 2 its motor shafts 1 of car door 1 cavity to pass through to be connected is meshed with turbine 4, the travelling gear 6 that is located on the turbine rotation axle 5 is meshed with ratch 7, vertical rod 22 upper ends that are connected as a single entity with ratch 7 are provided with moving runner 10, this moving runner withstands on the arc pull bar 9, with the hinged bearing pin of arc pull bar 9 other ends be located at connecting rod 11 with slide opening in, promptly work as vertical rod with a ratch left side, when the right side moves horizontally, moving runner 10 drives arc pull bar 9 and connecting rod 11 rotates, thereby it is flexible to drive locking bar 12, opens with this pass of realizing car door lock.Be located at door contact interrupter control panel 18 hinged with the slide bar in the slide opening 17 16 with an end of push rod 15, the other end of push rod 15 is hinged with the locating shaft 14 that is located on the car body, door contact interrupter control panel 18 is with a ratch left side or move right, and by slide bar, the rotation of push rod drive car door, the stroke that slide bar moves in slide opening just makes car door lock open.Locking bar 12 is basic identical with door-hinge 13 and original vehicle structural.Sequence number 8 and 21 among the figure is respectively closes door limit switch and door open limit switch.

The other end of driving lever 24 that electromagnet 23 connects places on the travelling gear shift fork 25, and travelling gear shift fork 25 places on the backstay 27.After the electromagnet energising, drive the driving lever action, and the travelling gear shift fork is moved by driving lever, break away from ratch, but this moment just hand switch car door, after the electromagnet dead electricity, back-moving spring 26 will drive the travelling gear shift fork and move, and travelling gear is resetted, and be meshed with ratch.

Sequence number 19 is locating wheel among the figure, and sequence number 20 is the locating wheel track.

Claims
