Reference picture 1, Fig. 3, the installed in front of vehicle frame 1 can slide up and down slipper bracket 34, the upper hinge of slipper bracket 34 Rollover stand 35 is connected to, the lower end of rollover stand 35 can be flipped up, overturning drive device is provided between vehicle frame 1 and rollover stand 35, should Overturning drive device includes branch sleeve 38, adjusting nut 39, fixed seat 36, adjusting rod 37, and the lower end of branch sleeve 38 is with turning over The lower end of pivoted frame 35 is hinged, and adjusting nut 39 is fixedly connected on the upper port of branch sleeve 38 at, and fixed seat 36 is hinged on On vehicle frame 1, the upper end of adjusting rod 37 is rotatably connected in fixed seat 36, and the upper end of adjusting rod 37 is provided with crank, adjusting rod 37 Bottom be inserted into through adjusting nut 39 in branch sleeve 38, adjusting rod 37 be provided with adjusting nut 39 match it is outer Screw thread.Goods can be moved up and down, so as to realize the center of gravity regulation to transport vehicle, led to by sliding up and down for slipper bracket 34 The angle of inclination of goods can be changed by crossing the flip angle of change rollover stand 35, so can also realize the center of gravity tune to transport vehicle Section, rollover stand 35 is turned over turn 90 degrees after can form wider platform, be easy to arrangement of goods, because adjusting rod 37 with adjusting nut 39 is Threaded connection, rotates crank, and adjusting rod 37 moves up and down relative to adjusting nut 39, thus rollover stand 35 can be driven to overturn, such as The flip angle that fruit is held turned over frame 35 is constant, by rotating crank slipper bracket 34 can also be driven to rise or fall, passed through Such regulation to center of gravity of goods can make transport vehicle keep balance, it is not necessary to which user exerts oneself to help.

Damping swing arm 40 is installed, the middle part of damping swing arm 40 is rotatably connected on axletree 2 on reference picture 2, Fig. 4, axletree 2 On, wherein one end of damping swing arm 40, which is provided with damping wheel 41, axletree 2, is connected with support arm 42, is equipped with damping swing arm 40 Flexible chain 43 is connected between one end of damping wheel 41 and support arm 42, is connected between the other end and support arm 42 of damping swing arm 40 It is connected to damping spring 44.Damping wheel 41 is used to contact with step surface prior to crawling wheel 4 when downstairs, to mitigate trailing wheel to step Impulsive force.

In the present embodiment, this can stair activity power-assisted transport vehicle power set using motor 19 and by motor The reductor 20 of 19 drivings, powers, battery can be installed on vehicle frame 1, by control circuit controling motor 19 for convenience Velocity of rotation, handlebar 45 control circuit and rotates arrangements for speed regulation, between motor 19 is electricity provided with rotating arrangements for speed regulation Connection, rotating arrangements for speed regulation can be using the similar device on existing electric bike handlebar, and rotating handlebar be able to can change The rotating speed of motor 19, so as to change the speed of the traveling of transport vehicle.

Transport the course of work of goods upstairs and can refer to Fig. 8, Fig. 9, place goods onto after vehicle frame 1, adjusted by rotating Crank on bar 37 adjusts the position of centre of gravity of goods, mixes up after center of gravity, and vehicle is in poised state, catches handlebar 45 by transport vehicle Pull at stair, front end arrangement of clutch 18 is in power engagement state by controlling the hand on handlebar to apply the handbrake, wheel carrier 3 is in power Device is rotated by（Wheel carrier 3 is rotated counterclockwise in Fig. 8, Fig. 9）.By control the hand on handlebar to apply the handbrake to make it is middle from Attach together and put 17 in power released state, 17 pair of the 3rd drive 15 of middle arrangement of clutch now has stopping function, actively Bevel gear 8 is also at arrested state, and because wheel carrier 3 is to rotate, in the presence of distributing means for power supply, crawling wheel 4 reversely turns It is dynamic（Wheel carrier 3 is rotated counterclockwise in Fig. 8, Fig. 9）.As shown in figure 8, when transport vehicle is on step surface, crawling wheel 4, which is rotated, to be made Vehicle is obtained to walk to the direction gone upstairs；As shown in figure 9, when running into step, wheel carrier 3 crosses step, vehicle rises one upwards Step.Because crawling wheel 4 is to rotate during upstairs, crawling wheel 4 has to be acted on grabbing, and can prevent transport vehicle from falling Move back.

Transport the course of work gone downstairs of goods and can refer to Figure 10, Figure 11, by control the hand on handlebar to apply the handbrake to make front end from Attach together and put 18 in power released state, power set no longer have driving effect to wheel carrier 3, by controlling the hand on handlebar to pinch Lock makes middle arrangement of clutch 17 be in power engagement state.As shown in Figure 10, crawling wheel 4 is positive under the driving of power set turns Dynamic, crawling wheel 4, which is rotated, causes vehicle to be walked to the direction gone downstairs；As shown in figure 11, when going at step, one of them is climbed Road wheel 4 is fallen on next step, and step surface is touched so that before, damping wheel 41 can touch platform first in latter crawling wheel 4 Terrace, subsequent latter crawling wheel 4 is slowly implemented, and this reduces impulsive force of the crawling wheel 4 to step surface, transport vehicle is gone downstairs When it is more gentle.

Wheel carrier 3 in the present embodiment employs the angle between cross wheel carrier, the adjacent two wheel carriers support arm of cross wheel carrier For 90 degree, just matched with step, and using after this structure, crawling wheel 4 is of moderate size, the institute of wheel carrier 3 in the course of work The resistance and torsion being subject to are smaller.

In summary, the utility model is not limited to above-mentioned embodiment.Those skilled in the art, are not departing from this reality On the premise of with new spirit and scope, some changes and modification can be done.Protection domain of the present utility model should be with this reality It is defined with new claim.
