Described control circuit board 3 comprises: central process unit, accelerometer, gyroscope, motor drive, battery protection.Wherein, described accelerometer and the gyroscope barycentre offset that angle of inclination and pitch velocity degree of will speed up meter and gyroscope detect during the inspection vehicle running body respectively feeds back to central process unit; by specific algorithm, adjust the balance of car body front and back; described motor drives side-play amount and the motor feedback speed according to central process unit; export suitable PWM ripple and control brshless DC motor, described battery protection is overcharging, crossing and put and overcurrent of protection battery.Described battery 4 is located at the inside of casing 2, and the power of car load operation is provided.Be generally lithium cell or storage battery.
As shown in Figure 2, electric locomotive wheel consists of center shaft 10, wheel hub motor 11 and tire 12.Tire 12 is arranged on wheel hub motor 11, and center shaft 10 is located at wheel hub motor 11De center.In battery-driven car when operation energising,, wheel hub motor 11 is around center shaft 10 rotations, and center shaft 10 is also as the central fixed shaft of whole car body.
Fig. 3 illustrates exploded drawings and the inner space deployment scenarios of Self-balancing electronic wheelbarrow casing.Casing 2 is the cover panel of car body, and for the protection of inner body, battery cover 15, be used to assembling battery, respectively is provided with an attaching parts 17 in electric locomotive wheel 6 both sides, and attaching parts 17 is provided with center shaft connecting bore 19 and the handle mechanism installation portion 18 of handle mechanism is installed.Attaching parts 17 is fixed in casing 2, and attaching parts 17 is for being connected to form an integral body by handle mechanism 100, casing 2 and electric locomotive wheel 6.Described casing 2 is made by high-intensity plastics usually.Described attaching parts 17 generally is made of metal.Casing 2 inside, casing handle 1 lower zone is circuit board slot 14, the upper space of being close to casing 2 is battery case 16.The handle mechanism 100 that can fold is arranged on handgrip installation portion 18, and the center shaft 10 of electric locomotive wheel 6 connects by center shaft connecting bore 19.
Fig. 4 illustrates that Self-balancing electronic wheelbarrow handle mechanism 100 folds, the schematic diagram when stretcher 5 closes, and the car body size is little, compact conformation, convenient carrying and depositing while not driving.
Fig. 5-8 illustrate according to the Self-balancing electronic wheelbarrow of first embodiment of the invention and open stretcher 5, upwards pull out respectively handle stem 8 and lower handle stem 7, open handgrip handle 9, reach the process of hand-holdable driving condition.
Fig. 9 A-9D is for folding the handle arrangement decomposing schematic representation of handgrip Self-balancing electronic wheelbarrow according to a kind of band of first embodiment of the invention.As shown in Fig. 9 A-9D, the handgrip handle positioning structure of first embodiment of the invention comprises: open spacing draw-in groove 20, fold spacing draw-in groove 21, retracing spring 22 and limited screw 23.As shown in Fig. 9 C, 9D, limited screw 23 is locked on handle, and limited screw 23 is outer is provided with retracing spring 22, and between limited screw 23 and handgrip, has between the upper exhaust of certain altitude 90.Between upper exhaust, 90 height is more than or equal to the spacing height 91 of spacing draw-in groove.
As shown in Figure 10 A, when handgrip handle 9 was in opening, it falls within opened among spacing draw-in groove 20.When upwards mentioning handgrip handle 9 to after higher than spacing height 91, as shown in Figure 10 B, handgrip handle 9 inwardly rotates to an angle together with limited screw 23, retracing spring 22 shrinks handgrip handle 9 is resetted downwards, handgrip handle 9 just in time falls into and folds spacing draw-in groove 21, enters thus the stable collapse state as shown in 10C.Similarly, handgrip handle 9 can oppositely enter stable opening by collapse state by this handle positioning structure.
As shown in Figure 11 A, folded handle structure in the first embodiment of the present invention is for fully telescopic, and its structure comprises: upper handle stem 8, upper handle stem locating part 29, upper handle stem registration device 30, handle stem sheath 31, lower handle stem 7, lower handle stem registration device 32 and attaching parts sheath 33.Upper handle stem sheath 31 and lower handle stem sheath 33 snap in mounting hole 93A, the 93B that lower handle stem 7 and attaching parts 17 sides are provided with by elastoplast projection 92A, 92B respectively.Handle stem locating part 29 as upper as Figure 11 B, 11C is stuck on upper handle stem 8 from the side by locating part rigging pin 34.
Figure 12 A, 12B are the structural representations of upper handle stem registration device 30, and its structure comprises: upper handle stem registration device main component 35, upper handle stem registration device rigging pin 36, upper handgrip registration device dowel hole 37, upper handle stem locating dowel pin 38, upper handgrip registration device retainer spring 39.By upper handle stem registration device rigging pin 36, upper handle stem registration device 30 is installed on upper handle stem 8.Upper handgrip locating dowel pin 38 can be at upper handgrip registration device dowel hole 37 interior fore and aft motion, while in lower handle stem 7, pulling handle stem 8, upper handgrip locating dowel pin 38 may fall into four even spaced apart upper handle stem knock hole 47 places on lower handle stem 7, thereby reaches the purpose of flexible handle stem height.
Figure 12 C, 12D are the constructionals drawing of lower handle stem registration device 32, and its structure comprises: lower handle stem registration device main component 40, lower handle stem registration device rigging pin 41, lower handle stem registration device retainer spring 42, lower handle stem locating dowel pin 43, latch 46.By upper handle stem registration device rigging pin 41, lower handle stem registration device 32 is installed on lower handle stem 7.Latch 46 inserts on lower handle stem locating dowel pin 43 from the top down, make lower handle stem locating dowel pin 43 by lower handle stem registration device retainer spring 42 from lower handle stem registration device main component 40, ejecting, latch 46 is provided with the latch positioning bar 45 and latch limit rib 44 of retaining simultaneously, makes latch assemble rear and stand-alone assembly of registration device main component 40 formation.Latch 46 exists inclined-plane to contact 95 with lower handle stem locating dowel pin 43, latch 46 has certain for the geocoded activity space pressed down, pressing bolt 46, contact 95 by inclined-plane and promote to make the lower handle stem registration device retainer spring 42 of lower handle stem locating dowel pin 43 compressions, thereby inwardly shrink downwards.Lower handle stem locating dowel pin 43 can be in lower handgrip registration device dowel hole fore and aft motion, when the barre 7 of working under sb. pulls up and down in attaching parts 17, lower handle stem locating dowel pin 43 may fall into lower handle stem knock hole 94 places of two diverse locations of Figure 11 A, further reaches the purpose of flexible handle stem height.
Upper handle stem registration device 30 and lower handle stem registration device 32 can reasonably exchange application.
As shown in Figure 13 A-13B, when upper handle stem rose to extreme higher position, the upper handle stem locating dowel pin 38 of upper handle stem registration device 30 was ejected by upper handgrip registration device retainer spring 39, fell on the highest upper handle stem knock hole 47 in position on lower handle stem 7.
