Abstract
The utility model discloses a drive device of an automobile electric opening/closing door, which includes a power source, a clutch, a motion mechanism, a connecting rod, a rocker arm, a rotatable vertical column and a door panel, wherein the power source is connected with the motion mechanism through the clutch and drives the motion mechanism to synchronously rotate; the head end of the connecting rod is fixed on the motion mechanism, the tail end thereof is movably connected with the head end of the rocker arm; the tail end of the rocker arm is arranged at the top of the vertical column; and the column body of the vertical column is connected with the door panel. The vertical column is driven to rotate through the combination of the rotary motion of the power source and the linear motion of the connecting rod, so as to open/close the door; and the drive device has the functions of self-locking, pinch-preventing and manual-electric converting, has a simple structure, is highly safe and reliable, can prevent the possibility that the automobile door can not be opened/closed due to gas leakage in cold and hot seasons, ensures no shock during the driving of the automobile, and is stable in driving.
Description
Technical field
The utility model relates to a kind of vehicle doorn drive unit, in particular a kind of drive unit of vehicle electric switch door.
Background technology
Passenger vehicle vehicle door switch door drive mechanism is mainly with the compressed air source at present.Principle is that the source of the gas by certain pressure enters that air pump promotes piston rod and crank drives the door-hinge rotation, thereby drives opening/closing door of vehicle by pivoted arm.This device does not have the pinch resistant functionality poor stability simultaneously; High temperature and when high and cold gas easily leak, reliability and self-locking performance are poor; Car door is in service impact, and it is many to control mechanical trouble point again by circuit control gas circuit, and volume occupies very large space of compartment greatly simultaneously.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of drive unit of vehicle electric switch door is provided, and has realized driving to door contact interrupter thereby rotate to drive crank-link mechanism by power source.
Technical scheme: the utility model comprises power source, clutch, motion, connecting rod, rocking arm, rotatable column and door-plate; Wherein: power source rotates synchronously by clutch actuation movement mechanism, and the head end of connecting rod is fixed on the motion, and head end terminal and rocking arm is movably connected, and the end of rocking arm is arranged at the top of column, and the cylinder of column connects door-plate.
Described connecting rod and rocking arm constitute crank-link mechanism, and the rectilinear motion with reciprocal simple in structure is converted to the rotation of door-plate.
The cylinder of described column is provided with linking arm, and column links to each other with door-plate by linking arm, has realized that the column drive door-plate of rotation rotates together.
The top of described column is provided with the door-hinge head, the door-hinge head be fixed on column the top and and the end of rocking arm be fixedly linked.
Described connecting rod, rocking arm, rotatable column and door-plate respectively have two, and the head end of two connecting rods is separately fixed on the motion, and the angle between the connecting rod is 180 degree, and this structure can realize the door-plate of two fan doors is driven.
Described power source is electric-powered source, and electronic power supply can be ignored the influence of weather to power source, directly controls machinery by electric power, reduces fault.
Operating principle of the present utility model is: power source makes motion and power source realize that synchronous both forward and reverse directions rotates by clutch, forward and reverse rotation drivening rod of motion does reciprocating linear motion, further the driving rocking arm swings back and forth and drives column and rotates, the rotation of column drives the door-plate rotation by the effect of linking arm, realizes opening the door and closing the door.
Beneficial effect: the utility model has the following advantages compared to existing technology, thereby the utility model is realized the rotation that the rectilinear motion by connecting rod of rotatablely moving of power source drives column to open the door and close the door; Have the moving translation function of auto-lock function, pinch resistant functionality, torch simultaneously, simple in structure, have very high safety and reliability, and can not cause the car door can't switch season in freezing winter and in sultry summer because of gas leaks, guarantee not have in the vehicle operating and impact stable drive.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment is the vehicle of two fan doors, and drive unit comprises power source 1, clutch 2, motion 3, two connecting rods 4, two Rocker arm 5s, two rotatable columns 7, two linking arms 8, two door-plates 9 and two door-hinge heads 6; Wherein: power source 1 is selected electric-powered source for use, power source 1 links to each other with motion 3 by clutch 2 and actuation movement mechanism 3 rotates synchronously, the head end of two connecting rods 4 is separately fixed on the motion 3, angle between the connecting rod 4 is 180 degree, other assemblies are symmetrically distributed, the end of connecting rod 4 and the head end of Rocker arm 5 are movably connected; the end of Rocker arm 5 is arranged at the top of column 7; cylinder of column 7 connects door-plate 9; connecting rod 4 and Rocker arm 5 constitute crank-link mechanism; the reciprocal rectilinear motion of connecting rod 4 is converted to the rotation of door-plate 9; cylinder of column 7 is provided with linking arm 8, and column 7 links to each other with door-plate 9 by linking arm 8, and the column 7 of having realized rotation drives door-plates 9 and rotates together; the top of column 7 is provided with door-hinge head 6, the top that door-hinge head 6 is fixed on column 7 also and the end of Rocker arm 5 be fixedly linked.
As shown in Figure 2, when power source 1 drive motion 3 was rotated counterclockwise (counter-rotating), connecting rod 4 drove door-plates 9 and turns clockwise, and realizes opening the door; Otherwise when motion 3 turned clockwise (just changeing), connecting rod 4 drove door-plate 9 and is rotated counterclockwise, and realizes closing the door.
Because this drive unit is rotated by power source 1 actuation movement mechanism 3 and then the switch of realization door, the passenger can't open car door in the vehicle ' process, guarantees passenger vehicle door security reliability, has auto-lock function.The manual emergency handle can be set on clutch 2, and in case of emergency, the pulling handle disconnects power source 1, realizes opening Door by Hand.
