Description
Technical field
The utility model relates to a kind of safety that is used for the motor battery-driven car and props up wheel, belongs to motor bike, battery-driven car accessory device technical field.
Background technology
Many weeks, motor bike, battery-driven car have characteristics such as quick, laborsaving, convenient, are that people go on a journey or the important walking-replacing tool and the vehicle of belongings.But, because motor bike, the battery-driven car of two-wheel has only former and later two wheel supporting and running, so in the process of moving, in case when something unexpected happened is taked emergency brake, traffic accidents such as tumble injury personnel, damage vehicle take place very easily.In addition, vehicle because its support that is used to support and ground contact surface are less, so there is contact promptly might cause vehicle to topple over slightly, causes its stop dangerous in the stop process.
Summary of the invention
The purpose of this utility model is to provide a kind of driving safety, stop the safety that failure-free is used for the motor battery-driven car props up wheel.
Its technical scheme is: a kind of safety that is used for the motor battery-driven car is propped up wheel, comprise connecting panel, frame set, shock absorber, screw mandrel, DC machine and journey controller, it is characterized in that: left and right two connecting panels flexibly connect a frame set by hinge respectively, the middle part in this frame set outside is respectively by wheel of axle captive joint, the inner lower angle place of framework is inclined upwardly respectively and is hinged with shock absorber, flexibly connect the identical screw mandrel of a thread rotary orientation on two shock absorbers respectively, left and right screw mandrel passes the motor mounting plate umbrella gear that has been threaded respectively; The negative thread rotation direction of the umbrella gear that is threaded on the left and right screw mandrel is identical; DC machine is fixed on the below of motor mounting plate, be fixed with on its output shaft with left and right screw mandrel on the umbrella gear ingear umbrella gear that is threaded; The stroke gear mesh of fixing in parallel on the fixing gear of screw mandrel end in the journey controller and the DC machine output shaft.
Its technique effect is: the connecting panel that the utility model safety is propped up on the wheel is fixed on the shock absorber body frame of two-wheeled motor vehicle or battery-driven car hind axle, has promptly constituted the motor bike and the battery-driven car of many wheels.When on the less road surface of pedestrian and other vehicle, travelling, connect the power supply of DC machine, it is just changeed, by with the umbrella gear ingear umbrella gear that is fixed on its output shaft, the left and right screw mandrel of transmission is simultaneously done displacement upwards, thereby drive that two frame sets are done to make progress simultaneously and the relative motion of amounting to, make a wheel that is fixedly mounted on the outer middle side part of frame set break away from the road surface, minimizing vehicle friction force in the process of moving; Meanwhile, two identical nuts of thread rotary orientation that are threaded in the journey controller on the screw mandrel move right simultaneously, when the nut on the screw mandrel right side moves to the stroke (being the height that frame set rises to setting) of setting, butt is fixed on the collision block of the travel switch on the journey controller underframe right side, the trip switch promptly automatically cut off and switch DC machine power supply.When on the more road surface of pedestrian and other vehicle, travelling, then can connect the reverse electrical source of DC machine, make its counter-rotating, by with the umbrella gear ingear umbrella gear that is fixed on its output shaft, the left and right screw mandrel of transmission is simultaneously done downward displacement, thereby drive two frame sets and do external-open downward and in opposite directions motion simultaneously, make be fixedly mounted on the outer middle side part of frame set a wheel gradually near and contact the road surface; Meanwhile, be threaded in the identical nut of two thread rotary orientations on the screw mandrel in the journey controller simultaneously to left movement, when the nut on the screw mandrel left side moves to the stroke (promptly being installed in a wheel contact road surface of middle side part outside the frame set) of setting, butt is fixed on the collision block of the travel switch on the journey controller underframe left side, the trip switch promptly cut off automatically and switch DC machine power supply; During vehicle parking, also can operate equally, a wheel is landed, thereby strengthen the reliability that stops.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a journey controller structure scheme drawing of the present utility model.
The specific embodiment
As shown in Figure 1, the safety that is used for the motor battery-driven car is propped up wheel, comprises connecting panel, frame set, shock absorber, screw mandrel, DC machine and journey controller.Left and right two connecting panels 8 flexibly connect a frame set 10 by hinge 7 respectively, the middle part in this frame set outside is respectively by wheel 9 of axle captive joint, the inner lower angle place of framework is inclined upwardly respectively and is hinged with shock absorber 5, flexibly connect the identical screw mandrel of a thread rotary orientation 4 on two shock absorbers respectively, left and right two screw mandrels pass motor mounting plate 3 umbrella gear 2 that has been threaded respectively.The negative thread rotation direction of the umbrella gear 2 that is threaded on the left and right screw mandrel is identical.DC machine 11 is fixed on the below of motor mounting plate, be fixed with on its output shaft with left and right screw mandrel on the umbrella gear ingear umbrella gear 1 that is threaded.The stroke gear mesh of fixing in parallel on the fixing gear of screw mandrel end in the journey controller and the DC machine output shaft.
Journey controller 6 is made of underframe, screw mandrel, nut, nut guide plate and travel switch.Be fixed with screw mandrel 62 on the underframe 61, two nuts 63,64 that thread rotary orientation is identical at interval are threaded on the screw mandrel, be fixed with nut guide plate 64 on the underframe of nut one side, on the underframe of nut opposite side fixed interval have collision block on 65,66, two travel switches of two travel switches can be respectively with screw mandrel on two corresponding butts of nut.The stroke gear of fixing 12 in parallel meshes on the fixing gear 68 of screw mandrel end and DC machine 11 output shafts.Journey controller is fixed on a side of DC machine 11.
During use, the connecting panel 8 that safety is propped up on the wheel is fixed on the shock absorber tressel of two-wheeled motor vehicle or battery-driven car hind axle, and motor mounting plate 3 is fixed on the main car frame of shock absorber top of two-wheeled motor vehicle or battery-driven car hind axle and gets final product.
