The utility model relates to a four wheel child carriage which is especially suitable for the children who are 5 years old to 7 years old to use, comprising a carriage frame, a front and a back shafts, a carriage seat and four wheels, wherein, a swing arm type carriage frame comprises the carriage frame, a swing arm and a spring, and the back shaft is a bent shaft structure. The lower end of a hand rocker is hinged with the front end of a connecting rod, and the back end of the connecting rod is hinged with the middle part of the bent shaft. A steering plug is vertically connected with the middle part of a front auxiliary shaft through a balancing plug, the steering plug and a front main shaft form a steering shaft together, and the four wheel child carriage is reversed through pedals. The centre of gravity of the carriage is low, and the stability quality is good. During use, the carriage body heaves, and the vibration is little. The children's pleasure is increased, and the whole body of the children can obtain exercise.

Description

Four wheel child carriage
The utility model belongs to a kind of perambulator, is specially adapted to the four-wheel perambulator that the children in 5-7 year use.
Existing perambulator is generally three-wheel vehicle, foot-operated f-w-d, motive position was few when children used, another kind is the bicycle that similar adult rides, and just each parts is smaller, and this vehicle speed is fast, the adult's rim brakes that adopt more, children's hand is little, and strength is limited, can not guarantee timely braking, and children's balance, capability of reaction and experience are not so good as the adult, easily mis-use breakdown.Chinese patent discloses CN86208106u horse type carriage for children, its shell resembles horse, and driver train is made up of three axles, two rotating casings and one group of connecting rod, by the push-and-pull head of the horse, both feet are pedaled stretcher, four wheels just once move, and resemble a horse alive and slowly move forward, and have played the increase children interest of playing, and the effect that can take exercises, but this bassinet structure complexity, because mobile speed of advance is slow, child will lose interest slightly greatly.In sum, still there is not at present the perambulator that desirable suitable 5-7 year children use.
The purpose of this utility model is to overcome the weak point in the above-mentioned perambulator and provides a kind of simple in structure, and stability is good, the four-wheel perambulator that the suitable especially 5-7 that can make that children's whole body obtains taking exercise year children use.
The purpose of this utility model is achieved in that this four-wheel perambulator comprises vehicle frame, before, rear axle, vehicle seat, four wheels, before four wheels is contained in respectively in twos, on the rear axle, preceding, rear axle connects to ground respectively, and its vehicle frame is the spring shock absorption swing arm type, king pin and swing arm running-fit, when turning to, make between king pin and the swing arm to relatively rotate, in the trick force process and the reaction of ground-surface situation, the swing that can make the relative vehicle frame of swing arm produce certain angle, form rising and falling regularly of vehicle frame, reduce vibrations simultaneously, rear axle is a crankshaft structure, joystick lower end and the hinge joint of connecting rod front end, rod rear end and the hinge joint of bent axle middle part, the push-and-pull joystick drives bent axle by connecting rod and rotates, thereby driving driving wheel rotates, other wheel also rotates thereupon, and king pin is by balancing plug and preceding countershaft vertical connection of middle part, and preceding countershaft two ends are fixed by footstalk and forward spindle, constitute steering shaft, torsion is housed on the king pin returns positive spring.Make car turn to the back self-aligning, to overtake, two stretchers about fixing on the front axle of front axle (comprising forward spindle, preceding countershaft) and king pin junction, foot-operated turning to.
The utility model is owing to adopt the four-wheel structure, ground contact area is big, and center of gravity is low, and stability is good, in use, children's hand, arm, waist, leg, pin are worked simultaneously, make whole body obtain motion, and the fluctuating of vehicle body makes children feel novel, car can move forward and backward quickly simultaneously, suitable 5-7 year children use, and simple in structure, implement easily.
The drawing explanation of accompanying drawing:
Fig. 1 is the structural representation of four-wheel perambulator
Fig. 2 is that four-wheel perambulator A is to view
Fig. 3 is that four-wheel perambulator B is to view
Among the figure: front-wheel (1), forward spindle (2), preceding countershaft (3), balancing plug (4), stretcher (5) turns to guide (6), king pin (7), torsion return positive spring (8), swing arm (9), spring (10), joystick (11), vehicle frame (12), vehicle seat (13), main car frame (14), subframe (15), rear axle (16), crank (17), bent axle (18), trailing wheel (19), connecting rod (20), footstalk (21), rocker pins (22), swing arm guide (23), strengthen arm (24), stirrup (25), swing arm center pin (26).
Embodiment is described in further detail below in conjunction with (accompanying drawing): as shown in the figure, this four-wheel perambulator comprises vehicle frame (12), forward spindle (2), preceding countershaft (3), rear axle (16), vehicle seat (13), wheel (1,19) four, wherein two wheels (1) are contained on the forward spindle (2), two wheels (19) are contained on the rear axle (16), rear axle (16) is a crankshaft structure, the one end is captiveed joint with a trailing wheel (19), be driving wheel, the other end is connected with another trailing wheel (19) bearing, be flower wheel, forward spindle (2), rear axle (16) is connected with vehicle frame (12), by vehicle frame (12), swing arm (9), springs (10) etc. constitute spring shock absorption swing arm type vehicle frame, the front end of the swing arm on this vehicle frame (9) is welded on and turns on the guide (6), thereafter the upper end links with vehicle frame (12), the posterior end is connected with spring (10) front end, the rear end of spring (10) is connected with subframe (15), and to reduce the vehicle body vibrations, the inside that turns to guide (6) is king pin (7), it is by balancing plug (4) and preceding countershaft (3) the vertical connection of middle part, and preceding countershaft (3) two ends are fixed with footstalk (21) and forward spindle (2) and constituted front axle.Torsion is housed on the king pin (7) returns positive spring (8), two stretchers (5) about being fixed with on the front axle of front axle and king pin (7) junction, foot-operated turning to, at the middle part of main car frame (14) vehicle seat (13) is housed, its height is adjustable, the middle and lower part of joystick (11) links in main car frame (14) front portion with rocker pins (22), it is stabilized on the vehicle frame, joystick (11) lower end and the hinge joint of connecting rod (20) front end, connecting rod (20) rear end and the hinge joint of bent axle (18) middle part, when push-and-pull joystick (11), driving bent axle (18) by connecting rod (20) rotates, whole rear axle (16) rotates, order about driving wheel and roll, other wheel also thereupon rotating car to overtake or draw back, when joystick (11) pushes away or holds when motionless, trailing wheel (19) promptly stops operating and produces braking, makes car slack.As shown in Figure 3, stirrup (25) is housed in the rear end of vehicle frame (12) and strengthens arm (24),, guarantee the concentricity of bent axle (18) in order to increase the support strength of bent axle.
