Abstract
The utility model discloses a backshaft structure of an electric and pedal three-wheeled pram, which comprises a pram frame, a back shaft sleeve tube, and a back shaft, wherein, the back shaft comprises a fixing shaft and a moving shaft, wherein, one L-shaped hole is arranged on the back shaft sleeve tube; one limiting screw bolt can penetrate through the L-shaped hole and be combined with a positioning screw hole on the moving shaft, causing that the back sleeve and the moving shaft form the fixing coupling. The moving shaft can make the back shaft sleeve pipe shift towards left and right through the L-shaped hole; thereby, back wheels sheathed on the back shaft are coupled with or separated from a driving gear of the motor; the electric or the pedal two working conditions of the pram can be respectively adapted.
Description
1. technical field
The utility model relates to the back axle construction of electric pedal dual-purpose toy tricycle.
2. technical background
If toy tricycle is electrically operated, then generally perambulator is advanced by the motor-driven trailing wheel; If foot-operated, then foot-operated front-wheel advances perambulator, trailing wheel is driven by front-wheel, trailing wheel must keep relative free with hind axle, and the trailing wheel of electric three-wheel perambulator is subjected to the damping of drive of motor gear not free, thus the electric three-wheel perambulator generally all can not can ride again simultaneously, but people wish that again toy tricycle not only can be electronic but also can ride, the back axle construction of the utility model electric pedal dual-purpose toy tricycle proposes for this hope that satisfies people.
3. utility model content
The purpose of this utility model is achieved in that the back axle construction of electric pedal dual-purpose toy tricycle, it includes vehicle frame, rear-axle tube and rear axle, described rear axle includes anchor shaft and movable axle, its left rear wheel and off hind wheel are positioned respectively on anchor shaft and the movable axle, and form rotatable the connection with it; The electric gear roller box is fixed on the vehicle frame, movable axle passes the centre hole of a transmission gear of this electric gear roller box, the drive wheel of this transmission gear and a wounded in the battle keyway inner chamber forms one, on movable axle, the right side of off hind wheel is followed successively by wheel cap and card cap, the left surface center of off hind wheel has cavity, the periphery of this cavity is the flange that has spline, accommodate packing ring and stage clip between the inner chamber of the cavity of off hind wheel left surface and the wounded in the battle keyway of drive wheel, spline on the flange of off hind wheel left surface and drive wheel with spline can be meshing with each other; Rear-axle tube is provided with " L " shape hole, having a caging bolt to pass this " L " shape hole combines with positioning screw hole on the movable axle, rear-axle tube and movable axle are formed to be fixedly connected, owing in rear-axle tube, be provided with " L " shape hole, make movable axle in rear-axle tube, to move to left or to move to right, be separately fixed at two diverse locations, thereby make and to be enclosed within trailing wheel on this with the drive of motor gear coupling or separate, adapt to electronic or foot-operated two kinds of mode of operations of perambulator respectively.

. the specific embodiment
Referring to Fig. 1, Fig. 2, the back axle construction of electric pedal dual-purpose toy tricycle, it includes vehicle frame (1), rear-axle tube (2) and rear axle, described rear axle includes anchor shaft (3) and movable axle (6), and vehicle frame (1), rear-axle tube (2), anchor shaft (3) connect into an integral body by electric welding: electric gear roller box (4) is fixed on the vehicle frame (1) by bolt of rear end plate (5); The left rear wheel of perambulator and off hind wheel (9) are positioned respectively on anchor shaft (3) and the movable axle (6), and form rotatable the connection with it; Movable axle (6) passes the centre hole of (4) transmission gears of electric gear roller box (14), this transmission gear (14) forms one with the drive wheel (12) of a wounded in the battle keyway inner chamber, on movable axle (6), the right side of off hind wheel (9) is followed successively by wheel cap (8) and card cap (7), the left surface center of off hind wheel (9) has cavity, the periphery of this cavity is the flange that has spline, accommodate packing ring (10) and stage clip (11) between the inner chamber of the cavity of off hind wheel (9) left surface and the wounded in the battle keyway of drive wheel (12), spline on the flange of off hind wheel (9) left surface and drive wheel (12) with spline can cooperatively interact.Rear-axle tube (2) is provided with " L " shape hole, having a caging bolt (13) to pass this " L " shape hole combines with positioning screw hole (15) on the movable axle (6), rear-axle tube (2) is formed with movable axle (6) to be fixedly connected, owing in rear-axle tube (2), be provided with " L " shape hole, make movable axle (6) in rear-axle tube (2), to move to left or to move to right, be separately fixed at two different positions, thereby make the trailing wheel that is enclosed within on this connect or separate, adapt to electronic or foot-operated two kinds of mode of operations of perambulator respectively with drive of motor gear (14).Fig. 1 is the expansion drawing in " L " shape hole on the rear-axle tube (2), in this " L " shape hole, be provided with " A ", " B " two positions, movable axle (6) moves to left in rear-axle tube (2) when caging bolt (13) is in position " A ", at this moment the dual-purpose toy tricycle is in motoring condition, movable axle (6) moves to right in rear-axle tube (2) when caging bolt (13) is in position " B ", at this moment the dual-purpose toy tricycle is in foot-operated state, Fig. 2 is the situation of caging bolt (13) when being in position " A ", at this moment movable axle (6) is to moving to left, because card cap (7) is fixed on the end of movable axle (6), make off hind wheel (9) move on the position of drive wheel (12) by card cap (7) to the pressure of wheel cap (8) like this, stage clip (11) is compressed, spline on the off hind wheel (9) is meshed with the spline of drive wheel (12), motor one energising so, transmission gear (14) just drives off hind wheel (9) with drive wheel (12) and rotates, thereby perambulator is advanced.
Referring to Fig. 3, in the time will realizing foot-operated the driving, " B " that caging bolt (13) moved to " L " shape hole locates, movable axle this moment (6) moves right, stage clip (11) recovers to loosen, and the elastic force of the pressured spring of off hind wheel (9) (11) also moves right, and the spline on the off hind wheel (9) separates with spline on the drive wheel (12), off hind wheel (9) just is not subjected to the restriction of transmission gear (14) and drive wheel (12) and can freely rotates like this, thereby realizes the forward foot-operated function that perambulator advances that drives of taking turns.
