Abstract

The saddle height of a children's tricycle sold in the current market is constant; the existing children's tricycle is not lively and interesting. The utility model is characterized in that two back wheels of a children's tricycle can be connected through crankshafts; the crankshaft, a saddle and a front vertical frame are connected through connection bars; two connection bars are arranged between the saddle and the crankshaft; the saddle and the front upright frame are connected through the connection bar. The saddle can move upwards and downwards when the utility model is in use; the activity amount and the interesting performance are increased; the utility model is good for child's body-building.

Description

Undulant saddle children's tricycle
The utility model belongs to entertainment for children, health and fitness facilities.
The children of the Xiao Shouing three-wheel vehicle of riding usefulness is steady travelling in the market, and the vehicle seat standing height can not change, and lacks activity, interest.
But the purpose of this utility model is the toy tricycle of a kind of vehicle seat heave and set formula of design motion, rises and falls while advancing, and makes children by bike that the sensation of the gesture of riding be arranged, and increases interestingly, and increases the whole body activity, helps body-building.
Main points of the present utility model are: be connected with bent axle between two trailing wheels of toy tricycle, bent axle to vehicle seat has rear linking rod to connect, and bent axle has lower link to be connected with preceding perpendicular frame, has boxed rod to be connected between vehicle seat and the preceding perpendicular frame.Bearing before one is arranged on the preceding perpendicular frame of this perambulator, is right after a rear support under the vehicle seat, forward and backward bearing be for connect bent axle, connecting rod is used.Two trailing wheel axis holes and bent axle are for being fixedly hinged, rear linking rod can be two, rear linking rod and bent axle can be and be movably hinged, rear linking rod and rear support are that active pin shaft is hinged, and two lower links are arranged between crankshaft two end and preceding bearing, and lower link and bent axle can be and be movably hinged, lower link and preceding bearing can be and be fixedly hinged, a boxed rod is arranged between the forward and backward bearing, and boxed rod can be active pin shaft with preceding bearing and connects, and boxed rod and rear support can be and be fixedly hinged.
This perambulator bent axle as shown in Figure 4, crankshaft axis both ends length L 1Can be 60mm-190mm, bent axle middle part (part parallel to the ground) length L 2Can be 120mm-380mm, included angle between crankshaft axis and sweep oblique line 1Can be 30 degree-90, write music axle middle part part parallel to the ground and oblique line included angle 2Can be 90 degree-150 degree, bent axle diameter R can be 8mm-14mm.
For adjusting the vehicle seat fluctuating frequency, scalable front and back wheel ratio can be 1:1, but also front-wheel is slightly little, and trailing wheel is big slightly, also can be opposite.When this perambulator was advanced, front-wheel was a drive wheel, drove lower link, and lower link drives bent axle, and bent axle drives trailing wheel and rear linking rod, and rear linking rod drives vehicle seat.In the crankshaft revolution process, bent axle middle part is during down to extreme lower position, and vehicle seat is minimum, and along with rotation, during the ground height maximum position of bent axle middle part, vehicle seat is promptly the highest, and in one week of wheel, vehicle seat rises and falls once, decides vehicle seat fluctuating speed according to the perambulator gait of march.Bent axle and the relevant connecting rod mechanism thereof, other wheels, preceding perpendicular frame, handlebar, pedal etc. can be identical with existing perambulator except that between trailing wheel for the utility model perambulator.
Description of drawings: Fig. 1 is a vehicle seat flighting schedule perambulator lateral plan, and Fig. 2 is the B-B section of Fig. 1, and Fig. 3 is the A-A section of Fig. 1, and Fig. 4 is the crankshaft part sketch drawing.(1) is preceding perpendicular frame among the figure, and (2) are preceding bearing, and (3) are boxed rod, and (4) are lower link, and (5) are vehicle seat, and (6) are rear support, and (7) are rear linking rod, and (8) are trailing wheel, and (9) are bent axle, and (10) are locating dowel pin, and (11) are baffle ring.
Front vertical frame (1) is other to be front bearing (2), vehicle seat (5) is lower to be rear support (6), upper connecting rod (3) is connected with front bearing (2) and rear support (6), back link (7) is connected with rear support (6) and bent axle (9), lower link (4) is connected with front bearing (2) and bent axle (9), bent axle (9) drives trailing wheel (8) rotation, and bent axle (9) drives back link (7) and moves up and down the undulatory motion of back link (7) drive vehicle seat (5) simultaneously. L in the bent axle (9)1Centered by line length on one side, φ1Centered by angle between line and sweep oblique line, φ2Be the angle of bent axle middle part part parallel to the ground with oblique line, L2Be the length of bent axle mid portion, R is the bent axle diameter. Alignment pin (10) and baffle ring (11) work the laterally slip effect on the connecting rod car bent axle that prevents.
The utility model has the advantages that: along with perambulator is advanced, the upper and lower fluctuating of vehicle seat, two dimensional motion increases enjoyment, children are had more attraction, because children's both feet will be with bigger strength to pedal by bike, both hands will more firmly be caught handle, increased the whole body activity, so not only vivaciously but also body-building.
Embodiment: adopt an existing toy tricycle repacking, the front and rear wheel dimension scale is 1.18:1, and front-wheel and trailing wheel horizontal throw are 460mm, R=12mm shown in the bent axle (pressing Fig. 2), L 1=100mm, L 2=270mm, φ 1=45 degree, φ 2=135 degree, crankshaft material is 45 #, connecting rod material is 16Mn.Rear linking rod length is 252mm, and boxed rod length is 328mm, and lower link length is 458mm, each two of back, lower links.Manufacture forward and backward bearing by preceding method, and connect each connecting rod and bent axle by its method of attachment.This perambulator is applicable to 4-10 year children.
