Please consult Fig. 2 and Fig. 3 earlier, be the electric wheelchair 20 of a preferred embodiment of the present invention, electric wheelchair 20 includes a vehicle frame 30, a pedal 40, a pair of first wheels 50, pair of driving wheels group 60, a pair of second wheels 70 and a pair of elastic device 80.
Two sides have a side lever 32 respectively about vehicle frame 30, and the front end of each side lever 32 has an outwards outstanding limiting section 322.Vehicle frame 30 has one first cross bar 34 and one second cross bar 36, first, second cross bar 34,36 all is fixed in side lever 32 front ends of vehicle frame 30 and first cross bar 34 is positioned at the top of second cross bar 36, and the two ends of first cross bar 34 and second cross bar 36 protrude in the side lever 32 of vehicle frame 30 respectively and form 2 first pivot ends 342 and 2 second pivot ends 362 respectively.In addition, vehicle frame 30 has plural upwardly extending support bar 38, uses for a seat group 90 assemblings.
Pedal 40 is fixedly arranged on second cross bar, 36 middle positions of vehicle frame 30 and is positioned at the front end of vehicle frame 30, uses when getting on or off the bus for user and tramples.
Each first wheels 50 is preceding wheels in the present embodiment, have one first wheel seat 52 and a first round 54, wherein first wheel seat 52 has first round pipe 522 and 1 first wheel carrier 524, the rear end of first round pipe 522 is hubbed at second pivot end 362 of second cross bar 36 of vehicle frame 30, front end then connects first wheel carrier 524, the first round 54 first wheel carriers 524 that are installed in first wheel seat 52.
Each drives wheels 60 and is middle wheels in the present embodiment, have one and drive a wheel seat 62 and a driving wheel 64, wherein drive wheel seat 62 and have an actuator 622 and a connection piece 624, actuator 622 1 sides connect driving wheel 64, opposite side sets firmly a CD-ROM drive motor 66, rotate in order to drive driving wheel 64, connector 624 is hubbed at first pivot end 342 of first cross bar 34 of vehicle frame 30, and be connected with actuator 622, and connector 624 has an arcual stopper slot 626, places in order to the limiting section 322 of the side lever 32 of the frame 30 of buying car in installments.When the connector 624 that drives wheels 60 be that the axle center pivot is when putting with first pivot end 342 of vehicle frame 30, connector 624 will because of the position-limiting action between the limiting section 322 of the two ends of stopper slot 626 and vehicle frame 30 only can be between a predetermined angular pivot pendulum, that is the pivot pivot angle degree size of connector 624 depends on the length of stopper slot 626.
Each second wheels 70 is the back wheels in the present embodiment, to be with these driving wheels 60 that benchmark is forward and backward corresponding with this each first wheels 50, have one second wheel seat 72 and one second and take turns 74, wherein second wheel seat 72 have one second take turns the pipe 722 and 1 second wheel carrier 724, second takes turns pipe 722 two ends connects second wheel carrier 724, the second respectively and takes turns 74 and be installed in second wheel carrier 724.
Each elastic device 80 includes a sleeve 82, a piston 84, an adjustment part 86 and a compression spring 88.One end of sleeve 82 is articulated in the connector 624 of the driving wheel seat 62 that drives wheels 60, and its outer peripheral face has screw thread 822; One end of piston 84 is articulated in the first round pipe 522 of first wheel seat 52 of first wheels 50, the other end stretch in the sleeve 82 and relatively sleeve 82 move up and down; Adjustment part 86 spiral shells are located at the screw thread 822 of sleeve 82 and can be screwed or unscrew; The two ends of compression spring 88 are contact adjustment part 86 and piston 84 respectively, by the buffering to provide first wheel seat 52 and driving wheel seat 62 relative vehicle frame 30 pivots to put.
See also Fig. 4, when electric wheelchair 20 travels when jolting the road surface, thrust 100 with the road surface is an example, the first contact protrusion thing 100 of the first round 54 meetings of electric wheelchair 20, still continue to be subjected to the propelling of driving wheel 64 this moment because of electric wheelchair 20, make that each first wheel seat 52 will be that fulcrum upwards lifts with second pivot end 362 of vehicle frame 30, climb up thrust 100 in order to drive each first round 54, to drive each elastic device 80 simultaneously upwards lifts, the piston 84 of this moment stretches in the sleeve 82 and pushes compression spring 88, in order to cushion suffered impact strength of each 54 first round.And, when each elastic device 80 upwards lifts, the connector 624 that interlock is again driven wheels 60 is that the fulcrum pivot pendulum that makes progress makes the limiting section 322 of vehicle frame 30 be positioned at stopper slot 626 rear ends of connector 624 with first pivot end 342 of vehicle frame 30, make the driving wheel 64 and the first round 54 can be closely against the road surface, to keep the vehicle body balance.
When electric wheelchair 20 travels to the depression road surface, as shown in Figure 5, each first round 54 is put downward pivot, and through the impact strength of each 80 each first round 54 of absorption of elastic device and the connector 624 downward pivots pendulum of interlock driving wheels 60, make the limiting section 322 of vehicle frame 30 be positioned at stopper slot 626 front ends of the connector 624 that drives wheels 60, thus, each first round 54 still is tight against the road surface and can keeps the vehicle body balance.
In addition, when desiring to leave the seat group 90 of electric wheelchair 20 when driver's pushes pedals 40, pedal 40 will bear the strength of driver's whole body and bestow the moment that second cross bar 36 1 of vehicle frame 30 rotates.But because first, second cross bar 34,36 of vehicle frame 30 forms two the first different pivot ends 342 and second pivot end 362 respectively in the both sides of vehicle frame 30, even second cross bar 36 of vehicle frame is subjected to the effect of moment, still being not enough to drive vehicle frame 30 pivots forward, therefore, the driver can leave the seat group 90 of electric wheelchair 20 safely and needn't worry that seat group 90 has the situation of toppling forward and takes place.
The present invention is hubbed at first pivot end and second pivot end of vehicle frame respectively with each first wheels and each driving wheel group, can allow structure of the present invention comparatively firm and have a preferable safety in utilization.
What must be illustrated is, three wheels described in the above embodiment of the present invention, that is comprise first wheels, drive the wheels and second wheels, yet on practice, whole electric wheelchair, two wheels of also only arranging in pairs or groups get final product, promptly comprise first wheels and drive wheels, and no matter these first wheels in the electric wheelchair combination of three wheels or two wheels, can be the front-wheel of electric wheelchair, or can be the trailing wheel of electric wheelchair.
The present invention is disclosed constituent components in preceding taking off all embodiment; only for illustrating; be not to be used for limiting the scope of the invention; scope of the present invention must be as the criterion with the scope of claim protection; substituting or variation of other equivalent elements, the scope that also should be claim protection of the present invention contains.
