detailed description

Please refer to Figures 1 to 3 of the first preferred embodiment of this utility model. It includes a support block 40 as a load-bearing component, and a control module 10, which is connected to one end of a main module 20 by a connecting member 210 (or directly connected without the connecting member 210), and the other end of the main module 20 is Connect a rear-wheel module 30 (the rear-wheel module 30 can be a two-wheel structure, and the illustration is just a single-wheel representative).

The control module 10 mainly includes: a control rod 11, which is inserted into a control sleeve 12 and then connected to a front fork 13 (or the end of the control rod 11 may be directly in a double-fork structure), and the front fork 13 utilizes two The end is connected to the front wheel 14.

The main body module 20 mainly includes: a base 21 whose tail is directly connected to the rear wheel module 30, a connecting member 210, a main support 22, a seat base 23, a seat 231 connected to a seat sliding sleeve 232, and The spring bolt 233 and the plurality of positioning holes 234 on the seat base 23 are provided.

In the balance bike mode, the support block 40 is connected to the control sleeve 12 of the control module 10. The upper part of the main support body 22 is pivotally connected to the seat base 23, and the lower part is pivotally connected to the rear end of the base 21 (the pivotal position of the main support body 22 and the base 21 is preferably at In the area of 2/5 of the rear end of the base 21, the main support 22 can be made longer in implementation so as to be able to support a taller user). The front end of the seat base 23 is hollow, and its cover is pressed on the support block 40 to connect the seat base 23 and the control module 10 to make the entire structure stable.

There is a bending part 235 at the front end of the seat base body 23, which allows the user to have a lower stepping threshold to facilitate the use of the balance bicycle. The seat base 23 is a seat section 236 behind the bending part 235. The seat sliding sleeve 232 can slide in the seat section 236, and by virtue of the cooperation of the spring pin 233 and the positioning hole 234, the seat 231 can be adjusted to different height positions. 3, the main support 22 can be collapsed on the base 21 to form a scooter mode, and most of the top surface of the main support 22 is a flat surface so that the user can easily and comfortably step on Above.

Next, please refer to Figures 4 and 5 of the second embodiment of the present invention. The seat base 23 may be a stepped multi-seat seat 25, on which there are a first seat 251, a second seat 252, a third seat 253, etc., which directly provide a plurality of seats of different heights.

Please refer to Figure 6 and Figure 7. The load-bearing element (support block 40) in the above-mentioned embodiment may be a fastener 41 located at the front end of the seat base 23, and the seat base 23 and the control sleeve 12 are connected in another way to achieve the purpose of bearing weight.

In addition, please refer to Figures 8 and 9 of the third embodiment of the present invention. The difference between this embodiment and the previous two examples is that there is no base, the main support body 26 and the seat base 27 are connected in an integral manner, the support element 42 is a load-bearing element and there is a positioning element 43 on the control module 10. There are load-bearing holes 421 at both ends of the supporting element 42, and there are positioning holes 431 at both ends of the positioning element 43. When the balance bike mode is used, the buckle (not shown in the figure) on the front edge of the seat base 27 is inserted into the load-bearing hole slot 421.
