Abstract
The utility model discloses a kind of pedal system with auxiliary wheel of self-balancing wheelbarrow, include two the pedal mounting rods vertically arranged being arranged on vehicle body both sides, and be arranged on two pedals of vehicle body both sides, below described pedal, auxiliary wheel is installed, described two pedal mounting rod in the vertical directions slidably connect sliding shoe, and described pedal is rotatably connected on sliding shoe by adapter shaft; Described pedal mounting rod top is connected with drive screw by bearing, and drive screw and a driver module be arranged in vehicle body are in transmission connection, and described sliding shoe forms towards the one side of pedal mounting rod the motion thread coordinating with drive screw and be in transmission connection; All be provided with to detect user foot above described two pedals and whether step down in sensor on pedal, described sensor and driver module are electrically connected with controller.This pedal system can make to get on or off the bus and become very easy, is beneficial to more people and easily learns to ride wheelbarrow.
Description
Technical field
The utility model belongs to wheelbarrow construction applications, is specifically related to a kind of wheelbarrow with auxiliary wheel.
Background technology
Self-balancing electronic wheelbarrow is a kind of driven by power, has the walking-replacing tool of homeostasis function; In today of social develop rapidly, traffic congestion has also become universal phenomenon, and electric unicycle replaces bicycle and battery-driven car to be development of fashion as the vehicle.The rise of Self-balancing electronic wheelbarrow, by the traffic revolution that initiation one is new; During the riding of existing electric unicycle, be all need first to step down on pedal with a pin, shank and sidewall offset, and form stable triangular structure, and then get in another leg station, thus realize riding action; But shank and sidewall offset very uncomfortable, ride for a long time and also can cause green grass or young crops of becoming silted up.Existing wheelbarrow is generally furnished with the auxiliary wheel that can removably connect with pedal, but this kind of auxiliary wheel only can be used in when begining to learn and find the sense of equilibrium for user, inapplicable when normally riding.
Summary of the invention
Technical problem to be solved in the utility model is: the pedal system with auxiliary wheel providing a kind of self-balancing wheelbarrow, thus solves the problems of the technologies described above.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of pedal system with auxiliary wheel of self-balancing wheelbarrow, include two the pedal mounting rods vertically arranged being arranged on vehicle body both sides, and be arranged on two pedals of vehicle body both sides, below described pedal, auxiliary wheel is installed, described two pedal mounting rod in the vertical directions slidably connect sliding shoe, and described pedal is rotatably connected on sliding shoe by adapter shaft; Described pedal mounting rod top is connected with drive screw by bearing, and drive screw and a driver module be arranged in vehicle body are in transmission connection, and described sliding shoe forms towards the one side of pedal mounting rod the motion thread coordinating with drive screw and be in transmission connection; All be provided with to detect user foot above described two pedals and whether step down in sensor on pedal, described sensor and driver module are electrically connected with controller.
Preferably: described driver module is stepping motor, and the output shaft of stepping motor is coaxially connected with drive screw.
Preferably: described pedal mounting rod vertically forms two dovetail furrows, described sliding shoe forms the swallow tail with described dovetail furrow sliding connection; Described pedal mounting rod forms the arc-shaped concave holding described drive screw in the one side of sliding shoe between two dovetail furrows.
Compared with prior art, the beneficial effects of the utility model are: when on the foot of user does not step on pedal or when only having a pin to step on pedal, sliding shoe is positioned at the position, bottom of pedal mounting rod, at this moment the auxiliary wheel lower surface below pedal is concordant with the wheel lower surface of wheelbarrow, like this when starting to ride, when only having a pin to step down on a pedal, the pressure that the side of vehicle body produces user's shank is less, even beginner's shank also not easily to extrude and injured because produce with vehicle body side, after two pin of user are all stepped on pedal, sensor on two pedals detects that two pedals are all trampled, then controller control step motor drives drive screw to rotate, thus two pedals are upwards risen along pedal mounting rod simultaneously, when stopping, user can to stand on tiptoe point by a pin, sole is made to cancel pressure to sensor, then controller control pedal moves down, to auxiliary wheel and earth surface, can stop reposefully like this.

Detailed description of the invention
According to shown in Fig. 1 to Fig. 4, the pedal system with auxiliary wheel of a kind of self-balancing wheelbarrow described in the present embodiment, include two the pedal mounting rods 2 vertically arranged being arranged on vehicle body 1 both sides, and be arranged on two pedals 4 of vehicle body both sides, auxiliary wheel 41 is installed below described pedal, described two pedal mounting rod in the vertical directions slidably connect sliding shoe 3, and described pedal is rotatably connected on sliding shoe by adapter shaft 43; Described pedal mounting rod 2 top is connected with drive screw 5 by bearing, drive screw and a driver module 6 be arranged in vehicle body are in transmission connection, and described sliding shoe forms towards the one side of pedal mounting rod the motion thread 32 coordinating with drive screw and be in transmission connection; All be provided with to detect user foot above described two pedals and whether step down in sensor 42 on pedal, described sensor and driver module are electrically connected with controller.
Described sensor is pressure sensor, and also usable contact button switch substitutes.
Described driver module is stepping motor, and the output shaft of stepping motor is coaxially connected with drive screw.
Described pedal mounting rod vertically forms two dovetail furrows, described sliding shoe forms the swallow tail 31 with described dovetail furrow sliding connection; Described pedal mounting rod forms the arc-shaped concave holding described drive screw in the one side of sliding shoe between two dovetail furrows.Described sliding shoe bottom forms the pedal connecting bore 33 passed for adapter shaft.
The below of described pedal is provided with two auxiliary wheels, and two auxiliary wheels are arranged along isoplanar, tread length direction.
When on the foot of user does not step on pedal or when only having a pin to step on pedal, sliding shoe is positioned at the position, bottom of pedal mounting rod, at this moment the auxiliary wheel lower surface below pedal is concordant with the wheel lower surface of wheelbarrow, like this when starting to ride, when only having a pin to step down on a pedal, the pressure that the side of vehicle body produces user's shank is less, even beginner's shank also not easily to extrude and injured because produce with vehicle body side, after two pin of user are all stepped on pedal, sensor on two pedals detects that two pedals are all trampled, then controller control step motor drives drive screw to rotate, thus two pedals are upwards risen along pedal mounting rod simultaneously, when stopping, user can to stand on tiptoe point by a pin, sole is made to cancel pressure to sensor, then controller control pedal moves down, to auxiliary wheel and earth surface, can stop reposefully like this.
After digging pedal in addition, the medial surface 40 of pedal is downward, and concordant with the lower surface of wheel, just can erectly place on the ground when such wheelbarrow does not use.
The on-off model that described controller is obtained by receiving sensor, thus the using state judging wheelbarrow, thus the movement controlling sliding shoe, the control program of controller is the prior art that those skilled in the art easily realize, and is again not described in detail.
