It can further be illustrated hereinafter.
Wherein, child's tricycle forerunner wheel 1 is in a level-one deceleration mode, an idle mode, a double reduction pattern And one between Full-Speed mode,
When child's tricycle forerunner wheel 1 is in primary speed-down pattern, which drives a wherein power Fluted disc 7,
When child's tricycle forerunner wheel 1 is in idle mode, which is detached from the power fluted disc 7,
When child's tricycle forerunner wheel 1 is in double reduction pattern, which drives another power teeth Disk 7,
When child's tricycle forerunner wheel 1 is in Full-Speed mode, which runs through the locking screw hole 251 and axis Pipe jack 103.
How to be used the following detailed description of child's tricycle forerunner wheel.Clear explanation for convenience, here covers a pair Body 2 is respectively labeled as lid 2A and lid 2B, and a pair of of power fluted disc 7 is respectively labeled as power fluted disc 7A and power fluted disc 7B.
As illustrated in figures 19 and 20, child's tricycle forerunner wheel 1 is in primary speed-down pattern, at this point, in pressure bullet It is entire that fixture block 11 is driven to slide into close to the side of power fluted disc 7B under the action of spring 14 so that the fixture block of a driving fixture block 11 Prominent 112 are embedded between the fluted disc fan block 72B of power fluted disc 7B.
When child's pushes pedals 42, entire drive component 9S directly drives the fluted disc of power fluted disc 7B to fan block 72B and carries out Power is then sequentially delivered to the lid of the second transmission gear 6, the first transmission gear 5 and lid 2B by rotation, power fluted disc 7B The rotating speed of tooth head 221, drive component 9S is reduced, then, entire wheel body with drive component 9S with lower speed forward Movement.By adjusting the transmission parameter of lid tooth head 221, the first transmission gear 5 and the second transmission gear 6, such as diameter, the number of teeth Deng to obtain ideal reduction ratio, general 0.5-0.6 is proper.
As shown in figure 21 and figure, child's tricycle forerunner wheel 1 is on idle mode.Specific operation process is as follows, User pulls the draw ring 81 for adjusting bracing wire 8, adjusts the traction traction column cap 16 of bracing wire 8, then, driving 15 synchronous drive of screw rod is driven Dynamic fixture block 11 is slided towards the direction of power fluted disc 7A, and compression spring 14 is extruded, until the fixture block of driving fixture block 11 protrudes 112 Deviate from between the fluted disc of power fluted disc 7B fan block 72B.On this position, entire to drive when user's pushes pedals 42 The power of component 9S is not transferred on wheel body.That is, when parent's hand-held bar carries out child, the foot of child can To be put on pedal 42, the position of pedal 42 will not be rotated with the rotation that forerunner takes turns, and forerunner's wheel or pedal is avoided to injure child Virgin foot, the foot of child feel more comfortable.
As shown in figure 23 and figure 24, child's tricycle forerunner wheel 1 is in double reduction pattern.Specific operation process is such as Under, user pulls the draw ring 81 for adjusting bracing wire 8, driving 15 synchronous drive of screw rod driving fixture block 11 to continue towards power teeth The direction of disk 7A is slided, and compression spring 14 continues to squeeze, and is embedded into power fluted disc until the fixture block of driving fixture block 11 protrudes 112 Between the fluted disc fan block 72A of 7A.Similar with primary speed-down pattern, the rotating speed of drive component 9S is reduced, then, entire wheel body As drive component 9S is travelled forward with lower speed.Although it should be noted that marking lid with the same label here Body 2 and power fluted disc 7, still, by the reduction ratio difference for the deceleration system that lid 2 is formed with power fluted disc 7, to obtain difference Deceleration mode.
As depicted in figs. 1 and 2, child's tricycle forerunner wheel 1 is on Full-Speed mode.Specific operation process is as follows, makes Lid screw rod 3 is directly run through locking screw hole 251 and central siphon jack 103 by user, then, drive shaft tube 10 and lid 2 it is opposite Position is locked, and when child's pushes pedals 42, entire drive component 9S directly drives lid 2 to be rotated, then, entire to take turns Body is travelled forward with drive component 9S with identical speed.
It should be noted that during adjusting the traction of bracing wire 8, guide card of the adjusting bracing wire 8 in drive shaft tube 10 It is slided in mouth 102 so that the pulling for adjusting bracing wire 8 is more smooth.When adjusting bracing wire 8 is drawn on scheduled position, directly It connects and the draw ring 81 for adjusting bracing wire 8 is anchored on the fixation skewed slot of corresponding fixed card column, for example the first fixation card column 43, second is solid Determine card column 44 or third fixes card column 45, corresponds to primary speed-down pattern, the idle mode and two of child's tricycle forerunner wheel respectively Grade deceleration mode.
As shown in Figure 25 to Figure 31, second of embodiment of system of riding for child's tricycle of the invention, at this time only Only show part-structure.Here, traction shaft 17A adjusts bracing wire instead of the traction column cap 16 in a kind of upper embodiment 8A is instead of the adjusting bracing wire 8 in a kind of upper embodiment.
Forerunner's wheel 1 hereinbefore is equipped between the bottom of vehicle frame 18A, being equipped with one on the tap of vehicle frame 18A quickly refers to Dial 19A.It is set on 19A there are one shift-up toggle and a downshift toggle in general, quickly referring to and dialling, refers to group 19A for controlling speed On bracing wire spooling length.
Traction shaft 17A is rotatably arranged in a wherein drive shaft tube 10A.It is set in the middle part of driving screw rod 15A Screw hole 151A is set in having one, is drawn shaft 17A removably and is rotatably arranged in this and sets in screw hole 151A.The axis of traction Bar 17A includes that the tail portion of traction a cylinder 171A, traction cylinder 171A is equipped with smooth a rotational segment 172A and a thread segment 173A, thread segment 173A are equipped with a rotating screw cap 178A, and the head of traction cylinder 171A is equipped with a bracing wire card slot 174A, It is respectively equipped with a bracing wire mounting hole 175A on the two side of bracing wire card slot 174A, a bracing wire is equipped in bracing wire mounting hole 175A The top of fixing pin 177A, traction cylinder 171A are equipped with a pair of of bracing wire guide openings 176A.
The tail portion of adjusting bracing wire 8A dials 19A with the quick finger and is connected, and the head for adjusting bracing wire 8A connects equipped with a bracing wire Head 82A, the bracing wire meet 82A and are connected with bracing wire fixing pin 177A.
Illustrate the application method of the embodiment below.
1, the downshift toggle for quickly referring to and dialling 19A is pressed, release adjusts bracing wire 8A, drives the fixture block of fixture block 11 to protrude 112 embedding Enter between the fluted disc fan block 72 of power fluted disc 7, child's tricycle system of riding is in primary speed-down pattern；
2, pressing quickly refers to the shift-up toggle for dialling 19A, adjusts bracing wire 8A and traction shaft 17A, traction shaft 17A is pulled to drive Screw rod 15A, the fixture block of driving fixture block 11 is driven to protrude 112 and deviate from between the fluted disc of power fluted disc 7 fan block 72, children's three-wheel Vehicle system of riding is in idle mode；
3, continue to press the shift-up toggle for quickly referring to and dialling 19A, adjust bracing wire 8A and pull on traction shaft 17A, driving card The fixture block of block 11 protrudes 112 and is embedded between the fluted disc fan block 72 of another power fluted disc 7, which is in In double reduction pattern；
4, lid screw rod 3 is passed through into locking screw hole 251 and a wherein central siphon jack 103, the top of lid screw rod 3 and traction The outer wall of cylinder 171A keeps a preset gap, the rotation of axis of traction bar 17A is not interfered, at this point, the child's tricycle is ridden System is on Full-Speed mode.
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.
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.
