Description
Technical field
The utility model belongs to wheelbarrow construction applications, is specifically related to a kind of self-balancing wheelbarrow with center of gravity self-regulating function.
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; Existing electric unicycle is when riding, user carrys out corresponding control wheelbarrow by adjustment forward lean or layback and advances or brake, when needing emergency brake in the process of riding with fast speed, health subconsciously can be swung back and wheelbarrow is braked as soon as possible by user greatly, but the excessive crank that easily causes of angle of layback causes falling, there is safety hazard, and the stressed conference excessively of the motor of wheelbarrow makes immediate current excessive, affects the service life of motor.
Utility model content
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of simple and ingenious structure, the self-balancing wheelbarrow with center of gravity self-regulating function of transition layback when can avoid user's sudden stop.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of self-balancing wheelbarrow with center of gravity self-regulating function, include car body and be arranged on two pedals on the erection column of car body both sides, described pedal is rotatably connected to a screw mandrel, be provided with a motor in order to drive screw mandrel to rotate in pedal, described screw mandrel is connected by screw-driven with described erection column; Described motor is electrically connected with the controller of wheelbarrow.
Preferably: the forward and backward mobile range of described pedal is 20-50mm.
Compared with prior art, the beneficial effects of the utility model are: when wheelbarrow speed is higher than (during wheelbarrow speed) during the second command speed, motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel, like this when needs brake, as long as user's health is swung back a little, center of gravity at once moves to wheelbarrow rear portion, can realize braking in time and ensure that user's amplitude of leaning back can not be excessive and cause falling down.In addition, when wheelbarrow speed is lower than (when wheelbarrow speed is lower) during the first command speed, motor drives screw mandrel rotation that pedal is moved to the front of wheelbarrow working direction, such user health that do not need to lean forward can keep wheelbarrow low speed and at the uniform velocity travel, thus reduce shank firmly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pedal part.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
embodiment 1
According to Fig. 1 and Fig. 2, a kind of self-balancing wheelbarrow with center of gravity self-regulating function described in the present embodiment, include car body 1 and be arranged on two pedals 3 on car body both sides erection column 2, described pedal is rotatably connected to a screw mandrel 4, be provided with a motor 5 in order to drive screw mandrel to rotate in pedal, described screw mandrel is connected by screw-driven with described erection column; Described motor is electrically connected with the controller of wheelbarrow, when wheelbarrow speed is lower than 5km/h, motor driving screw mandrel rotates forward and pedal is moved to wheelbarrow direct of travel front, when wheelbarrow speed is higher than 12km/h, motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel.
A notch portion is formed, the width 20-50mm larger than the width of erection column of notch portion, the amplitude that namely pedal is movable in the middle of described pedal.Described motor is arranged on side in pedal, and motor output shaft is directly coaxially connected with screw mandrel; Or motor output shaft connects train of reduction gears, and then the mouth of train of reduction gears is connected with screw mandrel.
The connection location of the first screw mandrel and pedal is near the top of pedal, and the bottom of pedal and erection column lateral wall offset thus can maintain horizontality after pedal is launched.
Described controller is equipped with gyro sensor and acceleration pick-up, gyro sensor controller is controlled state of equilibrium that wheelbarrow fore-and-aft direction is in level, when body gravity deflection front or rear, controller correspondingly controls motor forward or reverse, when the amplitude of user's body forward, rear-inclined is larger, the side-play amount that acceleration pick-up detects is larger, then controller correspondingly controls the rotating speed increase of motor.
For the electric unicycle that wheel is 14 inches, when wheelbarrow speed is higher than 12km/h, controller control motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel, like this when needs brake, as long as user's health is swung back a little, center of gravity at once moves to wheelbarrow rear portion, can realize braking in time and ensure that user's amplitude of leaning back can not be excessive and cause falling down.In addition, when wheelbarrow speed is lower than 5km/h, controller controls motor and drives screw mandrel to rotate pedal is moved to the front of wheelbarrow working direction, and such user health that do not need to lean forward can keep wheelbarrow low speed and at the uniform velocity travel, thus reduce shank firmly,
For the electric unicycle that wheel is 16 inches, can set when wheelbarrow speed is higher than 15km/h, motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel.
embodiment 2
A kind of self-balancing wheelbarrow with center of gravity self-regulating function described in the present embodiment, include car body 1 and be arranged on two pedals 3 on car body both sides erection column 2, described pedal is rotatably connected to a screw mandrel 4, be provided with a motor 5 in order to drive screw mandrel to rotate in pedal, described screw mandrel is connected by screw-driven with described erection column; Described motor is electrically connected with the controller of wheelbarrow, and car body is provided with a change-over switch in order to switch controller mode be electrically connected with controller; When change-over switch is positioned at the first state, mode is identical with embodiment 1, namely when wheelbarrow speed is lower than 5km/h, motor driving screw mandrel rotates forward and pedal is moved to wheelbarrow direct of travel front, when wheelbarrow speed is higher than 12km/h, motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel; When change-over switch pushes another state, controller mode changes, when wheelbarrow speed improves, motor driving screw mandrel rotates forward and pedal is moved to wheelbarrow direct of travel front, when wheelbarrow speed declines, motor driving screw mandrel rotates backward and pedal is moved to the rear of wheelbarrow direct of travel.
When change-over switch is in the first state, is suitable for using in or the uneven situation in ground more people, is beneficial to like this and brakes safely, identical with embodiment 1 object.When change-over switch is in the second state, is suitable for travelling (when namely not needing emergency brake) in spacious flat road surface, is particularly suited for travelling more at a distance; Specifically, after the speed of a motor vehicle improves, pedal moves forward, and user's center of gravity is moved forward, and such user's health did not just need to turn forward significantly.
