Embodiment
Below in conjunction with preferred embodiment; To details are as follows according to embodiment provided by the invention: see accompanying drawing for details; A kind of automatic control block selecting mechanism of intelligent vehicle comprises the automatic gearbox selector lever 1 of automobile, and said automatic gearbox selector lever is fixedly connected with electric pushrod mechanism 7 screw threads through U-shaped link 2; Push rod two ends in the said electric pushrod mechanism adopt moving fulcrum to connect; Said push rod front end is connected with automatic gearbox selector lever through ball stud 3, electric pushrod mechanism tail end pass through bearing pin and support 4 hinged, said electric pushrod mechanism is connected with the electronic control unit of control box 6.The reducing gear 5 of said electric pushrod mechanism adopts three grades of decelerations.Described electronic control unit connects and comprises photoelectric coupled device, single-chip microcomputer and the power drive parts that connect successively; Said photoelectric coupled device receives the TR signal respectively, is transferred to upper-position unit through the RS232 interface behind the TR signal that said single-chip microcomputer collection photoelectric coupled device receives.
The electric pushrod mechanism of conventional commodity is novel electric actuators, and the straight line executing mechanism that electric pushrod mechanism mainly is made up of mechanisms such as motor deceleration device, push rod and control gear can be realized distant control, centralized control.Electric pushrod is made back and forth movement in the certain limit stroke, general electric pushrod standard stroke is: 100,150,200,250,300,350, and 400mm, special stroke also can be customized according to the design of different application conditional request.Electric pushrod can design the electric pushrod of different thrusts according to different application load; General its maximum thrust can reach 6000N; No-load running speed is 4mm～35mm/s, and electric pushrod is a power source with the 24V/12V direct current permanent magnet motor, is converted into straight reciprocating motion to rotatablely moving of motor.
The present invention selects for use the electric pushrod product to be: 24V direct current supply, push rod maximum thrust are 2000N, and the push rod travelling speed is 3mm/s.
Mechanical part: electric pushrod is driven by direct current generator, can 24V be provided forward or backwards powered by direct current.When forward is supplied power; The driving of motor can make the retraction of the electric pushrod body of rod after three grades of decelerations, put by the P gear and put mobilely to the D gear thereby drive selection lever, and the body of rod stretches out when oppositely switching on; Drive selection lever by the D gear put put to the P gear mobile, thereby realize the choosing shelves of automobile.For the movement in a curve of the straight line motion that prevents the push rod body of rod and selection lever produces movement interference, the two ends of push rod need adopt moving fulcrum to connect.The push rod front end adopts ball stud to link to each other with selection lever.The push rod body of rod can unload from ball stud, selects shelves and the manually switching of choosing shelves automatically to realize vehicle; Its tail end adopts Vertical direction activity wring abut to connect;
Electronic control unit: automatically controlled part is used to provide electric pushrod to drive required 24V power supply, control galvanic supplier of electricity to, but make the electric pushrod bi-directional drive; Control the mobile position of electric pushrod in addition, the realization selection lever is accurately chosen positions such as P, R, N, D.
Electronic control unit adopts ATMega128 type single-chip microcomputer as main control chip.Single-chip microcomputer has program storage on the sheet (Flash Rom), electricity erasable memorizer (EEPROM) and data storage (RAM), need not external other storage chip.Carry out communication through the RS232 interface between single-chip microcomputer and the upper-position unit (computer).TR signal (P, R, N, D) input back adopts TLP521-4 type photoelectric coupled device to carry out the I/O port that photoelectricity isolation back gets into single-chip microcomputer, by being transferred to upper-position unit through the RS232 interface after the single-chip microcomputer collection.Upper-position unit then sends the command signal that changes gear through the RS232 interface and gives electronic control unit; Electronic control unit is accepted upper-position unit instruction back parsing needs to hang the gear of going into, and makes pliotron MMBT2222 conducting by single-chip microcomputer through I/O port output control signal then, and triode is the coil electricity of control relay CP2-12V again; Two output contact conductings; Thereby the connection motor power, the motor rotation drives push rod and moves forward or backward.In the process that the driven by motor push rod moves, single-chip microcomputer is constantly gathered gear signal, when reaching predetermined gear; Single-chip microcomputer output control signal is ended triode, the relay coil outage, and two output contacts break off; The motor dead electricity stops operating, the finishing control process.
Working procedure
As shown in Figure 2; When needs speed changer selection lever when " R " gear changes to " D " gear; It is " D " that control circuit receives " TR control signal ", detects " TR position signal " simultaneously when being " R ", both to electric pushrod motor input+24V; The retraction of the push rod body of rod is moved to " D " gear through ball stud pulling speed changer selection lever.When detecting " TR position signal ", control circuit when becoming " D ", stops+the 24V power supply, the push rod stop motion, and this moment, the speed changer selection lever just in time was positioned at " D " gear, promptly changed to " D shelves ".Otherwise, when needs speed changer selection lever when " D " gear changes to " N " gear, control circuit receives " N " control signal, and to detect current position be " D ", promptly to electric pushrod input-24V, the push rod body of rod stretches out, the promotion selection lever moves.When detecting position signal and become " N ", stop-the 24V power supply, change to " N " gear.
Working principle: utilize the ripe electric pushrod mechanism that uses, its pusher section is linked to each other with automatic gearbox selector lever, the electric pushrod body of rod links to each other with car body.The push rod body of rod stretches out when the longest, and selection lever just in time is positioned at " P (Parking) " position, and is as shown in Figure 1.When the push rod forward is connected 24V voltage; Body of rod retraction; Drive the selection lever process or stay in positions such as " R (reverse gear) ", " N (neutral) ", " D (driving) ", when push rod was oppositely connected 24V, the body of rod stretched out; Can be oppositely successively through or stay in " N (neutral) ", " R (reverse gear) ", " P (the Parking) " positions of etc.ing, thereby realize that the choosing shelves control.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
