Below in conjunction with the accompanying drawing and the specific embodiment this device is described further.
The specific embodiment
Referring to Fig. 1 to Fig. 7, the structure of this device is:
Lock panel 1 is provided with lock core 5, on the pedal 7 of vehicle body 11, is provided with cabinet 8, and described cabinet 8 is a rectangular configuration; Be provided with rotating shaft 14 in the cabinet 8, this device is preferred to adopt worm screw to replace rotating shaft 14, and rotating shaft 14 is parallel to the axletree setting on vehicle body 11; Rotating shaft 14 is erected on two side box plates of cabinet 8, and two outer with being located at cabinet 8 respectively supports of the two ends of rotating shaft 14 are captiveed joint, and two supports are positioned at the outside of pedal 7; One side of cabinet 8 inherent rotating shafts 14 is provided with motor 12, and motor 12 vertically is located on the pedal 7, and motor 12 is connected through worm gear 13 and rotating shaft 14; Be provided with rotating disk 18 away from motor 12 places in the rotating shaft 14, rotating disk 18 is connected with rotating shaft 14 through key, and rotating disk 18 is installed in the concentric rotary disk basement 15 in the cabinet 8; Rotary disk basement 15 is fixed on the pedal 7, and the outer peripheral face of rotating disk 18 is provided with a pair of centrosymmetric pin-and-hole 17, on whole vehicle body position; Two pin-and-holes 17 are up and down and vertically are provided with, and on rotary disk basement 15 and side face that rotating disk 18 cooperates, are provided with a pair of through hole that is 90 ° of layouts, on whole vehicle body position; A through hole is positioned at the top of rotary disk basement 15, and another through hole is positioned at a side of rotary disk basement 15, is provided with first spring 21 and bearing pin 19 of an assembly to using in each through hole; Through hole preferably adopts tapped bore, can adopt screw plug 20 to be encapsulated in the through hole first spring 21, bearing pin 19 and the scalable elastic force like this, and described bearing pin 19 is preferred to adopt a stepped bearing pin; Wherein an end can be used as spring bar and cooperates with first spring 21; And can on screw plug 20, be provided with through hole and cooperate with spring bar, realize elastic telescopic, two bearing pins 19 respectively flexibly connect axle 4 through one and are connected with the termination of driving lever 3; Described driving lever 3 is fixed on the lock core 5 and with lock core 5 and rotates synchronously; The two ends that on lock panel 1, also are provided with first trigger switch 2 and second trigger switch, 6, the first trigger switches 2 and second trigger switch 6 and driving lever 3 corresponding to two positions of lock core 5 are corresponding matching respectively, with 12 rotatings of control motor.
The opposite side relative with the side through-hole of rotary disk basement 15 is provided with a sector grooves on the inner peripheral surface of rotary disk basement 15; The cooresponding central angle of described sector grooves is 90 °; On the outer peripheral face of rotating disk 18, also be provided with contact block 23; The two ends of groove are respectively equipped with the 3rd trigger switch 22 and the 4th trigger switch 16, and contact block 23 cooperates with the 3rd trigger switch 22 and the 4th trigger switch 16 respectively, with stopping of control motor 12 rotatings.
Described each support comprises sleeve 9; Be provided with second spring 24 in the sleeve 9, supporting leg 10 stretches in the sleeve 9, and the end face of supporting leg 10 cooperates with the end face of second spring 24; The waist shaped holes that on supporting leg 10, are provided with a pair of center symmetry, axially place along sleeve 9; On sleeve 9, be provided with an anchor shaft and cross a pair of waist shaped hole, supporting leg 10 is fixed in the sleeve 9, make support become elastic support.
Support is in vertical when propping state, and the bearing pin 19 that is positioned at rotary disk basement 15 sides inserts the pin-and-hole 17 of rotating disks 18; When support was in the collapsed state of level, the bearing pin 19 that is positioned at rotary disk basement 15 tops inserted the pin-and-hole 17 of rotating disk 18.
The motor 12 of this device is electrically connected (not shown described driving direct supply in the accompanying drawing) with driving direct supply on the impersonal force vehicle.
Support is that the process of collapsed state is by propping state-transition:
Through key lock core 5 is turned to open position (not shown described key in the accompanying drawing) by off position; Driving lever 3 rotates with lock core 5 synchronously; The bearing pin 19 that will be positioned at rotary disk basement 15 sides is pulled out from pin-and-hole 17, and the bearing pin 19 at rotary disk basement 15 tops stretches out under the effect of first spring 21 and contacts with the outer peripheral face of rotating disk 18;
When driving lever 3 turns to when contacting with first trigger switch 2, motor 12 is just changeing, and rotating disk 18 rotates with rotating shaft 14 synchronously; Support rotates counterclockwise to collapsed state with rotating shaft 14; The bearing pin 19 at rotary disk basement 15 tops inserts the pin-and-hole 17 interior formation self-lockings of rotating disk 18, and the bearing pin 19 of rotary disk basement 15 sides stretches out under the effect of first spring 21 and contacts with the outer peripheral face of rotating disk 18, at this moment; The contact block 23 of rotating disk 18 is run into the 3rd trigger switch 22, and motor 12 stops operating.
Support by the process that collapsed state changes the state of propping into is:
Through key lock core 5 is turned to off position by the open position; Driving lever 3 rotates with lock core 5 synchronously; The bearing pin 19 that will be positioned at rotary disk basement 15 tops is pulled out from pin-and-hole 17, and the bearing pin 19 of rotary disk basement 15 sides stretches out under the effect of first spring 21 and contacts with the outer peripheral face of rotating disk 18;
When driving lever 3 turns to when contacting with second trigger switch 6, motor 12 counter-rotatings, rotating disk 18 rotates with rotating shaft 14 synchronously; Support clockwise rotates to propping state with rotating shaft 14; The bearing pin 19 of rotary disk basement 15 sidepieces inserts the pin-and-hole 17 interior formation self-lockings of rotating disk 18, and the bearing pin 19 at rotary disk basement 15 tops stretches out under the effect of first spring 21 and contacts with the outer peripheral face of rotating disk 18, at this moment; The contact block 23 of rotating disk 18 is run into the 4th trigger switch 16, and motor 12 stops operating.
It is thus clear that, form the opposite circuit of two-way through first trigger switch 2, second trigger switch 6 of lock core 5, driving lever 3 controls, realize the rotating (corresponding) of motor 12 with the opening and closing position of lock core 5; Stop operating through the 3rd trigger switch 22, the 4th trigger switch 16 control motors 12.
The circuit control principle of this device is:
Before the driving; Driving motor on the impersonal force vehicle is communicated with the driving direct supply; Through the mechanical action of the key that cooperates with lock core 5, realize that the just commentaries on classics of motor 12 also packs up support again, the impersonal force vehicle is able to driving (not shown described driving motor in the accompanying drawing);
After the parking; Driving motor on the impersonal force vehicle is broken off with the driving direct supply; Through the mechanical action of the key that cooperates with lock core 5, realize that the counter-rotating of motor 12 also props support again, prop up the impersonal force vehicle and lock; Close the driving direct supply on the impersonal force vehicle at last, the impersonal force vehicle is able to stop.
