Control circuit board 40 comprises central process unit, accelerometer, gyroscope, motor driving and battery protection; wherein; angle of inclination and pitch velocity the barycentre offset that degree of will speed up meter and gyroscope detect feeds back to central process unit when described accelerometer and gyroscope detect car body running respectively; the balance before and after car body is adjusted by specific algorithm; described motor driving, according to the side-play amount of central process unit and motor feedback speed, exports suitable PWM ripple and controls brshless DC motor.
Described stretcher 30 is located at the lower end, both sides of casing 20, and is connected with described attaching parts 80.Described stretcher 30 can be rotated down on certain angle.Be mainly used for driver to stand.Stretcher is made up of the Plastic Parts of metal or high strength usually.
Described battery 50 is located at the inside of casing, provides the power that car load runs.Be generally lithium cell or storage battery.
Described auxiliary wheels 70 are located at the lower end of car body, at least one group, left and right, and are provided with rotating mechanism, and its structure mainly comprises at least one auxiliary wheel, swinging strut and mounting bracket.Wherein, auxiliary wheel is arranged on swinging strut by the mode such as rivet or screw, and mounting bracket is arranged on bottom attaching parts by screw.Preferably, being also connected with pull bar lower beam of mounting bracket, to make auxiliary wheels more firm.Swinging strut and mounting bracket are connected into by lock screw etc. and make swinging strut can be mounted opposite support to rotate.Swinging strut can be made up of the plastics of metal or high strength.
Described auxiliary wheels normal driving, tow state under, the periphery of the wheel described in (exceeding) should be given prominence in described auxiliary wheel periphery, and with can fold hand combining, car body is when inclination certain angle, auxiliary wheel kiss the earth, makes user to tow vehicle.Auxiliary wheel should have certain terrain clearance, and there is certain angle on the straight line that its nadir and wheel nadir are formed by connecting and ground, and best angle should be greater than more than 30 degree, so as on vehicle during the slope of less than 30 degree auxiliary wheel can not connect and touch ground.
Described auxiliary wheel is under CAL or safe driving state, and described auxiliary wheel position should be located at immediately below stretcher, and coordinates with described stretcher and locate.To reach better auxiliary driving effect.The midway location that the position of best auxiliary wheel is located at stretcher is outer, so that study turns to while raising safety.
Lateral plan when Fig. 3 illustrates that the auxiliary wheel structure of Self-balancing electronic wheelbarrow is in abnormal driving state.As shown in Figure 3, under abnormal driving state, after stretcher is opened, driver stand on stretcher and carries out steering vehicle, and described auxiliary wheels 70 are located at car body front upper place, and are overhead provided with certain height, so that avoiding obstacles when car body is driven.There is certain angle [alpha] on the straight line that auxiliary wheels 70 nadir and electric locomotive wheel 60 nadir are formed by connecting and ground, and best α angle should be greater than 30 degree, is convenient to the slope of 30 degree and does not interfere with ground.
Lateral plan when Fig. 4,5 and 6 illustrates that the auxiliary wheel structure of Self-balancing electronic wheelbarrow is in two kinds of CAL states.As illustrated in figures 4-5, auxiliary wheels 70 rotate to CAL state by rotating mechanism, auxiliary wheel nadir should be provided with certain distance with ground, best H is high should deduct tire pressure by after heavy distortion, tilt when being greater than 10 degree, auxiliary wheel gets final product and earth surface, is convenient to control left-right balance when driver learns.
State difference shown in state shown in Fig. 6 and Figure 4 and 5 is, in Fig. 6, hand is folding.As shown in Figure 6, after hand handle folds, also can learn by described auxiliary wheel, increase the entertaining of study.When auxiliary wheels are in learning state, after described auxiliary wheel rotates, auxiliary wheel and wheel are substantially point-blank, described auxiliary wheel position should be located at immediately below stretcher, the midway location that the position of best auxiliary wheel is located at stretcher is outer, so that study turns to while raising safety.
Fig. 7 illustrates that balance electric wheelbarrow is in structural representation when towing state.As Fig. 7, auxiliary wheel with fold hand carrying for towing after combining, auxiliary wheel be located at car body left and right, lower end at least one.Car body is when inclination certain angle, and auxiliary wheel kiss the earth, makes user to tow vehicle.Do not begin a new line for car weight and feel painstaking.
After Fig. 8 and 9 illustrates that auxiliary wheels 70, stretcher 30, hand fold 10, the casing handle be provided with by casing 20 is carried, to carry when car body inconvenience tows.
Figure 10-14 illustrates the constructional drawing of the auxiliary wheels 71 of the Self-balancing electronic wheelbarrow according to the first embodiment of the present invention.As shown in FIG. 10 and 11, auxiliary wheels 71 are arranged on bottom attaching parts 80 by screw.Auxiliary wheels 71 comprise auxiliary wheel 711, swinging strut 712, mounting bracket 713, locating dowel pin 714, spring 715 and lock screw 716.Wherein, auxiliary wheel 711 is arranged on swinging strut 712 by modes such as rivet or screws 717, and mounting bracket 713 is arranged on bottom attaching parts 71 by screw 91.Preferably, mounting bracket is also connected with pull bar lower beam.Connect swinging strut 712 with mounting bracket 713 by lock screw 716 and form S. A..Described spring 715 is enclosed within the little head part of locating dowel pin 714 and loads in hole that mounting bracket 713 is provided with.Swinging strut 712 is provided with two concave surface 712a, makes two locating dowel pins 714 be positioned on described concave surface respectively, as shown in figures 12 a and 12b.
By the shape of the size and swinging strut 712 and mounting bracket 713 that suitably arrange auxiliary wheel 711, can make at normal driving with under towing state, the periphery of electric locomotive wheel is given prominence in auxiliary wheel periphery, and auxiliary wheel has certain terrain clearance, there is certain angle on the straight line that its nadir and electric locomotive wheel nadir are formed by connecting and ground, and this angle makes the auxiliary wheel when wheelbarrow downslope to connect and touches ground.
