Wherein, child's tricycle forerunner wheel is between a Full-Speed mode and an idle mode,
When child's tricycle forerunner wheel is in Full-Speed mode, which directly drives protecgulum fan block 33,
When child's tricycle forerunner wheel is in idle mode, which is detached from the protecgulum and fans block 33.
How to be used the following detailed description of child's tricycle forerunner wheel.
It is entire that fixture block 11 is driven to slide into close to protecgulum 3 under the action of compression spring 14 as shown in Figure 24 to Figure 28 Side so that the fixture block of driving fixture block 11 protrudes 112 and is embedded between the protecgulum fan block 33 of protecgulum 3.At this point, the first pedal assembly Limit trip 46 on 4 is stuck in the bottom of the first locating groove 101, the setting direction of the first pedal assembly 4 and the second pedal group Part 400 is mutually 180 degree.When child's pushes pedals 42, entire drive component 9S directly drives the protecgulum of protecgulum 3 to fan block 33 and carries out Rotation, then, entire wheel body are travelled forward with drive component 9S with identical speed.At this point, child's tricycle forerunner takes turns On Full-Speed mode.
As shown in Figure 29 to Figure 32, user, which directs out, stirs entire first pedal assembly 4 so that limit trip 46 from Deviate from first locating groove 101, then rotate the first pedal assembly 4, limit trip 46 is then snapped onto into the second positioning card In slot 102.Since the depth of the second locating groove 102 is less than the first locating groove 101, it adjusts bracing wire 8 and draws trussed shore First 16 so that traction column cap 16 is moved towards the direction of the first pedal assembly 4, then, drives 15 synchronous drive driving card of screw rod Block 11 is slided towards the direction of rear cover 2, and compression spring 14 is extruded, until the fixture block of driving fixture block 11 protrudes 112 from protecgulum 3 Deviate between protecgulum fan block 33.On this position, when user's pushes pedals, the power of entire drive component 9S will not pass It is delivered on wheel body.At this point, child's tricycle forerunner wheel is on idle mode.When parent's hand-held bar carries out child, The foot of child can be put on pedal, and the position of pedal will not be rotated with the rotation that forerunner takes turns, and forerunner is avoided to take turns or step on Plate injures the foot of child.As shown in Figure 31 and Figure 32, the setting direction of the first pedal assembly 4 and the second pedal assembly 400 are mutual At 0 degree, child can be placed in parallel foot, and the foot of child feels more comfortable.
It can be suitble to the child of different age group with the ride mode of unrestricted choice tricycle due to the use of person, it is safe. Parent is assured that riding for current tricycle by directly observing the angle of the first pedal assembly 4 and the second pedal assembly 400 Row pattern, and quickly adjusted by pedal assembly, it is convenient and efficient.
Not limited to this, any change or replacement expected without creative work should all cover the guarantor in the present invention Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
