Abstract
The utility model relates to an automatic landing gear of an electric vehicle, and belongs to an auxiliary parking tool. The automatic landing gear comprises a micro direct-current motor, a fixed clamp is fixedly mounted on the micro direct-current motor, an output shaft of the micro direct-current motor is connected with a screw, a nut is arranged on the screw, a clamping groove is formed in the nut, the fixed clamp is in rigid connection with a sleeve, a protrusion matched with the clamping groove of the nut is arranged on the inner surface of the sleeve, and a support rod is arranged between the screw and the sleeve and is in rigid connection with the nut. Rising and falling of the support rod are controlled via the motor to realize labor saving during parking of the electric vehicle. A support can move up and down freely by self-locking trapezoid thread transmission to set up a rear wheel of the electric vehicle so as to achieve the purpose of stable parking; moreover, the automatic landing gear of the electric vehicle is simple in structure, simple and convenient to operate, low in cost and widely suitable for parking of two-wheeled vehicles such as various electric vehicles and motorcycles.
Description
Technical field
The utility model relates to battery-driven car automatic elevator, belongs to the auxiliary instrument of parking.
Technical background
Battery-driven car automatic elevator is the accessory appliances while parking.At present conventional facility is for to prop trailing wheel with shelf, reach the object of parking the two-wheel cars such as battery-driven car, because battery-driven car, motor bike, self-aid vehicle vehicle body are heavier, so when parking, need, with expending muscle power greatly and process is loaded down with trivial details, for disadvantaged group, be challenges greatly.
Utility model content
The purpose of this utility model is to provide a kind of laborsaving, battery-driven car automatic elevator easily.
Technical solution:
The utility model comprises: DC micromotor, in DC micromotor, be installed with geometrical clamp, DC micromotor output shaft is connected with screw rod, screw rod is provided with nut, nut is provided with draw-in groove, and geometrical clamp and sleeve are rigidly connected, and sleeve interior surface is provided with the projection matching with nut draw-in groove, between screw rod and sleeve, be provided with pole, pole and nut are rigidly connected.
Described nut and pole integrative-structure.
Described nut is connected the trapezoidal self-locking thread of employing with screw rod.
The utility model is risen and fallen by electric machine control pole, labour-saving feature while realizing battery-driven car placement.By the transmission of self-locking Acme thread, support can freely be moved up and down, the trailing wheel of battery-driven car is propped, reach stable object of parking.
Accompanying drawing explanation
Fig. 1 is utility model front view;
Fig. 2 is the A-A figure of Fig. 1;
Fig. 3 is the B-B figure of Fig. 1.
The specific embodiment
The utility model is driven by promoting support realization and is parked by motor.
The utility model DC micromotor 1 is connected with geometrical clamp 8 by bolt 2, DC micromotor 1 output shaft is connected with screw rod 6 by coupler 4, key 3, screw rod 6 adopts trapezoidal self-locking thread to be connected with nut, geometrical clamp 8 is rigidly connected with sleeve 5, on nut, have the draw-in groove matching with sleeve 5 inside face projections, between screw rod 6 and sleeve 5, be provided with pole 7, nut and pole 7 integrative-structures.
During use, geometrical clamp 8 is fixedly mounted on vehicle frame, battery output DC powered DC micromotor 1 by battery-driven car, DC micromotor 1 middling speed is rotated, DC micromotor 1 output shaft is synchronizeed rotation with screw rod 6, the helical pitch of sleeve 5 forces pole 7 to move up and down, and screw rod 6 drives the reverse thread of pole 7 upper ends to rotate, and because helical pitch forces pole 7, moves up and down.Pole is stretched out certain length rear motor and is stopped operating, and because Acme thread has latching characteristics, after propping wheel, can not shrink, and reaches the object of parking.
