In the present embodiment, child's tricycle further includes push-rod assembly and saddle 6, and push-rod assembly and support component 8 are removable It is fixedly connected to form an entirety with unloading.In the present embodiment, the lower part of push-rod assembly is plugged in the installation of the lower part of support component 8 Kong Zhong.Saddle 6 is fixedly connected with bicycle beam component or sliding part 12.In the present embodiment, saddle 6 is fixedly connected with back rest mechanism 25, Saddle 6 does not rotate or moves relative to back rest mechanism 25 in entire folding process.
In the present embodiment, handlebar assembly 4 and front fork assembly 1 are rotatablely connected, between handlebar assembly 4 and front fork assembly 1 The length direction of rotary shaft is distributed along the front and back.Push-rod assembly include upper push-rod 10, lower push-rod 11 and be located at upper push-rod 10 top The handle 9 in portion, upper push-rod 10 are slidably connected along the length direction of lower push-rod 11 with lower push-rod 11.
Locked component further includes the Lock of handlebar mechanism for locking handlebar assembly 4 and the vehicle frame for locking frame main body Locking mechanism, Lock of handlebar mechanism include the handlebar unblock button 17 being arranged on front fork assembly 1, Lock of handlebar mechanism other Part is arranged in the tube intracavity of front fork assembly 1.
A kind of specific frame locking mechanism includes the handlebar unlocked button 16 being arranged on handle 9, frame locking mechanism Other parts be arranged in the tube intracavity of push-rod assembly.A kind of specific unlocking manner is, when pressing handlebar unlocked button It after 16, is unlocked between upper push-rod 10 and lower push-rod 11, when upper push-rod 10 is overlapped most with lower push-rod 11, under upper push-rod 10 contradicts Press section inside push rod 11, and then unlock the sliding of sliding part 12 and the rotation of support component 8.Another specific unlock side Formula is, after pressing handlebar unlocked button 16, the rotation of the sliding and support component 8 that unlock sliding part 12 is directly unlocked.
Another specific frame locking mechanism is that after push-rod assembly removal from child's tricycle, unblock button is set Set on the lower section of support component 8 or bicycle beam component, by press the unblock button can unlock sliding part 12 sliding and The rotation of support component 8.The specific structure of Lock of handlebar mechanism and frame locking mechanism is not described in detail, hereafter will be to its work original Reason is described in detail.
Child's tricycle in the present embodiment includes folded state and unfolded state,
When child's tricycle is located at unfolded state, as shown in Figs. 1-2, sliding part 12 is located at the back rest machine in bicycle beam component The rear portion of structure 25, handlebar assembly 4 and saddle 6 are in level, longest state of the push-rod assembly in stretching, extension, the also Cheng Zhili of support component 8 State, the convenient back to children carry out reliable comfortable support.The Rear frame 13 of two sides away from each other, two wheel assemblies 15 Parallel to each other and mutually separate, front component 2 and wheel assembly 15 and ground contradict, and realize the support to entire child's tricycle.
When child's tricycle is converted from unfolded state to folded state, first state as shown in Figure 3-4 presses at this time Handlebar unblock button 17 is unlocked handlebar assembly 4 by unfolded state, the handlebar assembly 4 of two sides is turned down separately down, so that vehicle Component 4 and 1 phase of front fork assembly are drawn close;The second state as seen in figs. 5-6, presses handle unblock button 16 at this time, will above push away Bar 10, which pushes down on, to be inserted into lower push-rod 11.
Further, push-rod assembly forward downward is rotated, and drives sliding part 12 along the back rest by first connecting rod component 7 The length direction forward slip of mechanism 25, sliding part 12 drive two Rear frames 13 to move forward, each Rear frame 13 backward on Side's rotation, while two wheel assemblies 15 move towards, child's tricycle is in the third state as Figure 7-8 at this time.? In some embodiments, when saddle 6 is fixedly connected with sliding part 12, saddle 6 can be with sliding part 12 together forward slip.
Continue push-rod assembly phase front rotated down, when child's tricycle is located at four state as shown in figs. 9-10, Sliding part 12 is located at the front of back rest mechanism 25, and bicycle beam locking mechanism is unlocked at this time, and front-axle beam mechanism 26 can be opposite around the 7th axis 5 It is rotated in back rest mechanism 25;Push-rod assembly is mutually drawn close with bicycle beam component, and Rear frame 13 mutually draws close with bicycle beam component and is located at bicycle beam The lower section of component, the plane where two wheel assemblies 15 intersect with each other and mutually draw close, and support component 8 and saddle 6 are simultaneously bonded.
When children trolley has the 4th state to convert to folded state as depicted in figs. 11-12, by front fork assembly 1 and front-axle beam Mechanism 26 is together around the 7th axis 5 rotated down backward, until front fork assembly 1 is mutually drawn close with bicycle beam component, Rear frame 13 at this time Between front fork assembly 1 and bicycle beam component, one end of the separate wheel assembly 15 of handle 9 and the separate front wheels of front fork assembly 1 One end of part 2 flushes or is substantially flush, and child's tricycle volume reaches minimum at this time.
Compared with prior art, child's tricycle provided in this embodiment passes through the sliding part 12 being arranged on bicycle beam component It realizes the folding of support component 8 and wheel assembly 15, while driving Rear frame 13 to rotate to diagonally above and backward by sliding part 12, i.e., Drawing close in opposite directions for the wheel assembly 15 of two sides is realized simultaneously, while reducing the transverse width of the child's tricycle of folded state And vertical height.Meanwhile in order to further decrease the volume of the child's tricycle of folded state, handlebar assembly 4 is folded down The length in front width direction can be reduced;Push-rod assembly is set as sliding over each other the upper push-rod 10 of setting and lower push-rod 11 can be with Reduce the child's tricycle length in the front-back direction of folded state;Front fork assembly 1 it is whole around the 7th axis 5 backward rotated down as The back rest is drawn close, and the height of the child's tricycle of folded state can be further reduced;It is unlocked by the sliding of sliding part 12 Bicycle beam locking mechanism between front-axle beam mechanism 26 and back rest mechanism 25, unlocking process are easy to operate.Folded child's tricycle It can will not still be contacted because of the other positions of child's tricycle by front component 2 and the self-support of wheel assembly 15 and ground Ground and cause cleaning the problem of.Child's tricycle overall structure in the present embodiment is simple and folding procedure is easy, shows Writing reduces the volume of child's tricycle when not in use.
Above disclosed is only the preferred embodiment in the utility model, cannot limit the utility model certainly with this Interest field, therefore equivalent variations made according to the patent scope of the utility model still belongs to what the utility model was covered Range.
