Description

The power-assisted hand buggy

The utility model relates to a kind of hand buggy, particularly a kind of power-assisted hand buggy.

Generally transport goods or during weight, be stack of articles to be put into spur hand buggy on the hand buggy again, general hand buggy is provided with a flat board, a dull and stereotyped end is provided with handle and should be provided with four wheels in the flat board below, be to utilize the manpower pulling during use, but, if the article of once stacking on hand buggy are too heavy, when just beginning to promote, can feel considerably painstaking, because static friction power is greater than dyanainic friction power, and friction can increase along with the positive force of weight, though can feel comparatively light after hand buggy promotes, still can feel painstaking when the article that pulling weighs.

Main purpose of the present utility model provides a kind of power-assisted hand buggy, and this hand buggy can provide auxiliary power.

The utility model comprises a hand buggy, an actuating device, a driving device and a control setup, and the bottom of this hand buggy has wheel; This actuating device comprises a CD-ROM drive motor and a propulsion source that connects CD-ROM drive motor with rotating shaft, and is assembled on this hand buggy; This driving device is one group of above planet gear meshed (planetary gear set) continuously, and an end is that input end, the other end are mouth, the rotating shaft of the input end of this driving device and this actuating device CD-ROM drive motor is meshing with each other, and this mouth is articulated with the wheel of hand buggy is coaxial; This control setup is electrically connected this actuating device, the action of controlling and driving motor.

Compared with prior art, power-assisted hand buggy of the present utility model can provide auxiliary power in use because of having actuating device, driving device and control setup, so have laborsaving, advantage easily when using this power-assisted to pull power.

Below by preferred embodiment and accompanying drawing power-assisted hand buggy of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the block diagram of the utility model one preferred embodiment.

Fig. 2 is the three-dimensional exploded view of the actuating device of the utility model power-assisted hand buggy.

Fig. 3 is the scheme drawing that the part of actuating device shown in Figure 2 is cut open.

Fig. 4 is the schematic perspective view of the utility model second preferred embodiment.

Fig. 5 is the schematic perspective view of the utility model the 3rd preferred embodiment.

As shown in Figure 1, 2, 3, power-assisted hand buggy of the present utility model includes: hand buggy 1, actuating device 2, a driving device 3 and a control setup 4.

This hand buggy 1 has a platform 11, and these platform 11 bottom surfaces are provided with four wheels 12, and the end on this platform 11 is provided with a handle 13.

This actuating device 2 comprises a CD-ROM drive motor 21 and a propulsion source 6 with rotating shaft 211, and this propulsion source 6 is an electric power storage battery at present embodiment, and this actuating device 2 is assembled in the middle of the bottom and a wheel relative about two 12 of this hand buggy 1.

This driving device 3 is one group of above planet gear meshed 31 continuously, in the present embodiment with the 31 corresponding engagements of three groups of planetary wheels, these driving device 3 one ends are input end 32, the other end is a mouth 33, comprise that an inner ring surface has the Ring gear of groove (ring gear) 311 and respectively organize planetary wheel 31, periphery is arranged with the planetary gear carrier 314 (gear carrier) that three planetary wheels (planet gear) 312 and another side central authorities are provided with a sun gear (sungear) 313, this planetary gear carrier 314 makes this three planets gear 312 and the engagement of Ring gear 311 inner ring surfaces, and each organizes planetary wheel 31 is combined in another group planetary wheel 31 with sun gear 313 three planetary wheel 312 central authorities; The input end 32 of this driving device 3 and the rotating shaft of these actuating device 2 CD-ROM drive motor 21 211 engagements, this mouth 33 is articulated with same axle with the wheel 12 of this hand buggy 1, whole transmission device 3 is had rotating speed that can reduce this CD-ROM drive motor 21 and the effect of transmitting torsion.

This control setup 4 is electrically connected the propulsion source 6 and the CD-ROM drive motor 21 of this actuating device 2, and to control this CD-ROM drive motor 21, this control setup 4 is two-period form change-over switches that only have the function of opening or closing.

This actuating device 2 and driving device 3 are assembled in the housing 5 that is installed in this hand buggy 1 bottom, and about two relative wheels 12 of while transmission symmetry, this CD-ROM drive motor 21 has left and right two rotating shafts 211, this two rotating shaft 211 connects a driving device 3 with planetary wheel 31 respectively, drives left and right two wheels 12 and rotates together.

When starting this control setup 4, this CD-ROM drive motor 21 begins to start and outputting power, respectively organize the wheel 12 that planetary wheel 31 rotates this hand buggy 1 by this driving device 3, make this hand buggy 1 that auxiliary power be arranged, cut off the electricity supply just passable as long as operate the switch of this control setup 4 when not needing auxiliary power, so the utility model can be when this hand buggy 1 carrying weight, open the auxiliary power of this actuating device 2, assist to promote the hand buggy 1 of quiescence, close actuating device 2 and promote Hou at this hand buggy 1, continue to promote with manpower fully, or continue auxiliary power is opened, can save strength.

Be an embodiment of the present utility model as shown in Figure 1, wherein actuating device and driving device are installed in wheel 12 places near hand buggy 1 handle 13 positions, Fig. 4 is another embodiment of the present utility model, wherein actuating device and driving device are installed in wheel 12 places of relative these hand buggy 1 handle 13 position other ends, as Fig. 5 is another embodiment of the utility model, and wherein actuating device and driving device are installed in the hand buggy of another kind of form.

In sum, power-assisted hand buggy of the present utility model, having really to provide auxiliary power to hand buggy, and reaches laborsaving, effect easily.
