The specific embodiment

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Referring to accompanying drawing, this electric bicycle ladder is identical with the installation site of former electric motor car with two wheels car ladder.Comprise connecting arm 25, support 10 and support retracing spring in the formation of this car ladder, connecting arm 25 is provided with installing and locating pin 1 and support locating dowel pin 5, and the support retracing spring is a cylindroid helical-coil compression spring 15.On the connecting arm 25 fixedly on hinge 24 and the support 10 set guide-track groove 8 hinged.Connecting arm 25 is provided with guide groove, and guide groove is to be connected in series the sealing annular groove that constitutes mutually by last deep-slotted chip breaker 18, arc lower groove 19 and vertical slots 20.Be fixed with pilot pin 6 on the support 10 relative with the sealing annular groove, pilot pin 6 places in the sealing annular groove.The inboard hinged catch 16 of annular groove, the profile of catch 16 can be identical with the inboard profile of sealing annular groove, catch 16 is provided with swing locating dowel pin 17, and locating dowel pin 17 matches with oval shape position-limited trough 26 on being located at connecting arm 25, and locating dowel pin 17 is provided with steel wire and steel disc retracing spring 2.Catch 16 is used for controlling the sense of motion of pilot pin in the sealing annular groove.Cylindroid helical-coil compression spring 15 is loaded on the guide rod 13, and guide rod 13 upper ends are fixed with upper spring seat 4, and sliding guide sleeve 14 is established in the lower end, and guide pin bushing 14 is fixing with support 10 welding, guide pin bushing 14 double as lower spring cups.Spring perch 4 upper ends are fixed with little guide rod 7 and engaging lug 21, fix 23 hinged connecting rods 22 of institute's ear that is fixedly coupled on engaging lug 21 and the connecting arm 25 with the little guide pin bushing 3 and the support of little guide rod 7 bearing fits.

For the ease of making, support 10 can be made of two oblong pillars 9 and a Connection Block 11 of being made by round steel, and 11 of pillar 9 and Connection Blocks can adopt welding manner to fix or screw 12 connection modes are fixed.

The use and the principle of work of this electric bicycle ladder are as follows: when parking battery-driven car, stir car ladder support 10 downwards with pin, support 10 is rotated around hinge 24, simultaneously, pilot pin 6 under the blocking of catch 16 can only along on deep-slotted chip breaker 18 be moved to the left, at this moment, the radius of gyration of support 10 connect to shorten, support retracing spring 15 pressurized gradually under the effect of connecting rod 22.When the afterbody of support 10 was about to land, it also leaned on very closely with the trailing wheel wheel rim of battery-driven car, promptly the afterbody of support 10 almost can turn to the battery-driven car trailing wheel under, in this course, the radius of gyration of support can shorten 25-30nm.When the support afterbody lands, be fixed in the high order end that pilot pin 6 on the support 10 also just in time moves to deep-slotted chip breaker 18, at this moment upwards gently carry electric motor vehicle tail with hand, and by means of the application force of spring 15, make pilot pin 6 slide into position as shown in Figure 3 20 times along vertical slots rapidly, the trailing wheel of battery-driven car is propped, and broken away from, make car be in the state of parking with ground.After loosing one's grip, when the weight of car body when pressing down, pilot pin 6 can be to 20 motions of upper edge vertical slots, when its upward movement 3mm left and right sides, the afterbody of the catch 16 that is reset blocks and can not continue to rise, pilot pin 6 is stopped by the inward flange of vertical slots 20 and arc lower groove 19 junctions simultaneously, and support 10 can not risen voluntarily.So it is as safe as a house reliable to park battery-driven car.

When state is parked in releasing, carry electric motor vehicle tail with have gentle hands, make pilot pin slide into the left end of arc lower groove 19 for 6 times, go-cart forward simultaneously, pilot pin 6 just moves right along arc lower groove 19, and under the effect of cylindrical screw compression reseting spring 15, reset rapidly, support 10 tail ends are risen, and be in the non-state of parking.
