TECHNICAL FIELD OF THE INVENTION
The present invention is a tricycle frame adjustment structure that can be adjusted according to the user's body shape and is convenient for accommodation and parking.
DESCRIPTION OF THE PRIOR ART
In a typical tricycle, the distance between the sitting position of the driver and the position of the cargo-carrying is fixed, and there is no way to adjust according to the stature of the driver. Therefore, it is quite inconvenient for the driver being too tall or short in using.
Furthermore, the volume used for the cargo-carrying part is usually not too small for a tricycle having a type of cargo-carrying. If the driving position volume is added, the overall volume will be too large, so it is easy to produce the bother of not finding the position to accommodate when accommodating or parking.
SUMMARY OF THE INVENTION
The main structure of the present invention comprises: a carrying-frame, direction-guiding wheels pivotally set on the carrying-frame, a connection component set at the side of the carrying-frame, a power-providing frame connected with the connection component, an adjustment component provided for connecting with the connection component, and a steering component set on the carrying-frame; wherein the connection component comprises a sleeving-connection element set at the side of the carrying-frame and a quick-dismantling component set on the sleeving-connection element; wherein the adjustment component comprises a assembly-connection element set at the side of the power-providing frame and a connection portion set on the assembly-connection element.
Through the above-mentioned structure, the user can penetrate the assembly-connection element of the adjustment component into the sleeving-connection element of the connection component; and the user can select any one of the connection portion to align with the position of the quick-dismantling component, thereby adjusting the distance between the power-providing frame and the carrying-frame to match the body shape of various users. After adjusting the distance, the quick-dismantling component and one of the connection portion are connected to each other, thereby connecting the carrying-frame and the power-providing frame to each other through the connection component and the adjustment component; and then pushing the carrying-frame through the power-providing frame, so that each direction-guiding wheel rotates to drive the tricycle to move.
When it is to be accommodated, the angle between the power-providing frame and the carrying-frame can be changed through the steering component, thereby reducing the volume occupied by the whole body; and the tricycle can be parked and accommodated in a narrower place to improve the convenience of the whole use.

Please simultaneously refer to FIG. 1 to FIG. 11, the user can first insert the assembly-connection element 441 of the adjustment component 44 into the sleeving-connection element 31 in the connection component 3 and allow the assembly-connection element 441 to telescopically move within the sleeving-connection element 31 to be in accordance with the user's body shape to adjust the distance between the power-providing frame 4 and the carrying-frame 2; after confirming the distance, the connection portions 442 closest to the through-hole portions 321 can be aligned with the positions of the through-hole portions 321; and as shown in FIG. 4, the axial-rod portion 322 can be simultaneously passed through each of the through-hole portions 321 and one of the connection portions 442 thereof; therefore, the assembly-connection element 441 can no longer move telescopically in the sleeving-connection element 31; please continuously refer to FIG. 5, after the axial-rod portion 322 passes through each of the through-hole portions 321, the tight-forcing element 323 will abut on the sleeving-connection element 31 (the tight-forcing element 323 of this embodiment is exemplified by a plastic gasket, but it is not limited); and the user can then engage the quick-dismantling handle 324 at one end of the axial-rod portion 322 (this embodiment is to engage the cam portion 3241 of the quick-dismantling handle 324 with the concave slot 3211 of the end of the axial-rod portion 322 as an example); thereby the quick-dismantling handle 324 can be mounted on the axial-rod portion 322; please further refer to FIG. 6, through the cam portion 3241 abuts with sleeving-connection element 31 and in cooperation with the effect of the tight-forcing element 323, pushing the position of the grip portion 3242, the quick-dismantling component 32 can be fixed to the sleeving-connection element 31; and the distance between the power-providing frame 4 and the carrying-frame 2 can be fixed; and then, each abutting position-limit piece 6 is locked into the sleeving-connection element 31; thereby the abutting position-limit piece 6 abuts with the assembly-connection element 441; because the abutting position-limit piece 6 is connected with the lock hole 311 of the sleeving-connection element 31 in the form of a thread locking in this embodiment, so that the locking depth of the abutting position-limit piece 6 can be adjusted; thereby the tightness against the limit of the assembly-connection element 441 can be adjusted to enhance the overall fixing effect, so that the user can step the power mechanism 42 on the sitting-chair portion 41 to drive the power wheel 43 to rotate, thereby pushing the direction-guiding wheels 22 to rotate to move the tricycle 1.
If wanting to park and accommodate, the quick-dismantling component 32 can be removed to separate the power-providing frame 4 and the carrying-frame 2 from each other for separate accommodation and parking; alternatively, as shown in FIG. 8 and FIG. 9, the user can pull the buckling-combining portion 533 of the fixing component 53 and disengage the buckling-combining portion 533 from the sticking-buckling portion 531 to allow the first docking portion 51 and the second docking portion 52 pivotally swing to each other; thereby changing the positional relationship between the power-providing frame 4 and the carrying-frame 2 to shorten the overall length. This method can be achieved simply by opening the fixing component 53, which is faster and simpler than pulling out the power-providing frame 4 after removing the quick-dismantling component 32; and which can improve the convenience of use.
Moreover, when the user wants to continue to use the mobile tricycle 1 to move, as shown in FIG. 10 and FIG. 11, the first docking portion 51 and the second docking portion 52 can be aligned with each other; then, the sticking-buckling slot 5331 of the buckling-combining portion 533 which can be buckled and combined with the sticking-buckling portion 531 is pushed via the swing effect of the connecting piece 532 to penetrate into the sticking-buckling portion 531 (the sticking-buckling portion 531 in the embodiment is a concave slot being able to be buckled and combined with the sticking-buckling slot 5331 correspondingly); and then, pressing down the other end of the buckling-combining portion 533 which faces away from the sticking-buckling slot 5331; at this time, the connecting piece 532 will make a swing movement using the pivot point pivotally connected with the second docking portion 52 as an axis; and the connecting piece 532 is made to close to the second docking portion 52, which will also bring the buckling-combining portion 533 to be close to the second docking portion 52; and, when the buckling-combining portion 533 is close to the second docking portion 52, the sticking-buckling slot 5331 can change the support length of the connecting piece 532 through changing the angle of the connecting piece 532; thereby gradually engaging into the ticking-buckling portion 531. When the buckling-combining portion 533 is abutted and combined with the second docking portion 52, the sticking-buckling slot 5331 can be completely engaged and fixed on the sticking-buckling portion 531 through the supporting force provided by the connecting piece 532; therefore the mutual position of the power-providing frame 4 and the carrying-frame 2 can be fixed through the buckling-combining portion 533 to allow the user to continue to use the tricycle 1.
