In the following description, specific details such as specific configurations and components are provided only to facilitate a comprehensive understanding of the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, descriptions of known functions and structures have been omitted.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] like Figure 1-5As shown in the figure, a multifunctional tricycle provided by this embodiment includes a frame 100200, a seat plate, a steering handle 300, a front wheel 500 and a rear wheel 700. The frame 100 includes a front frame 110 and a rear frame 120. One end of the front frame 110 is provided with a steering mounting sleeve 130, and the other end is inserted into one end of the rear frame 120. The front frame 110 and the rear frame 120 are detachably connected; the rear frame 120 is symmetrically provided with a rear wheel fixing frame 140; the seat plate 200 is detachable. The steering handle 300 is connected to a steering rod, which passes through the steering mounting sleeve 130 and is inserted into the top of the steering fork 400; the front wheel 500 is connected to the inner side of the lower end of the steering fork 400, and the pedals 600 are detachably mounted on both sides of the lower end of the steering fork 400; the rear wheel 700 is rotatably arranged on the outside of the fixing sleeve 800, and the rear wheel fixing frame 140 is inserted into the fixing sleeve 800, and the fixing sleeve 800 and the rear wheel fixing frame 140 are detachably connected.

[0031] Specifically, the tricycle of this embodiment is detachably connected to the front frame 110 and the rear frame 120, the seat plate 200 can be freely disassembled and assembled on the rear frame 120, and the footrest 600 can also be freely disassembled and assembled on the steering fork 400, making it easy to disassemble and assemble the entire tricycle, reducing its occupied space and facilitating transportation and storage; at the same time, the detachable footrest 600 can be adjusted as needed to meet the needs of different groups of people. When the footrest 600 is removed, the tricycle is switched to a three-wheeled scooter mode; In addition, the rear wheel 700 of this embodiment is detachably mounted on the end of the rear wheel fixing frame 140 through the fixing sleeve 800. After the two rear wheels 700 and the fixing sleeve 800 are removed from the rear wheel fixing frame 140, the original left rear wheel 700 and the fixing sleeve 800 are moved to the right and installed on the right rear wheel fixing frame 140, and the original right rear wheel 700 and the fixing sleeve 800 are moved to the left and installed on the left rear wheel fixing frame 140. At this time, the two rear wheels 700 are attached to each other, thereby switching the tricycle to a two-wheeled balance car mode.

[0032] Furthermore, in order to facilitate the disassembly and assembly between the rear wheel 700 and the fixing sleeve 800 and the rear wheel fixing frame 140, a first mounting groove is provided inside the rear wheel fixing frame 140, and a first button 141 is provided in the first mounting groove, and one end of the first button 141 is connected to a clamping protrusion 142; a first clamping groove 810 is provided at the bottom of the fixing sleeve 800; when the tricycle is in use, the rear wheel fixing frame 140 is inserted into the fixing sleeve 800, and the clamping protrusion 142 is clamped into the first clamping groove 810. When it is necessary to switch the use state of the tricycle, the first button 141 is pressed to move the clamping protrusion 142 out of the first clamping groove 810, so that the fixing sleeve 800 can be removed from the rear wheel fixing frame 140. At this time, the installation position of the rear wheel 700 can be changed, and the use mode of the tricycle can be switched.

[0033] Furthermore, in order to facilitate the disassembly and assembly between the front frame 110 and the rear frame 120, circular holes are provided on both sides of the end of the front frame 110 away from the steering mounting sleeve 130, and second mounting grooves 121 are provided on both sides of the end of the rear frame 120. The second mounting grooves 121 are provided with circular holes corresponding to the circular holes on the front frame 110, and a spring buckle is provided in the front frame 110, which can pass through the circular hole of the front frame 110 and enter the circular hole of the second mounting groove 121; a second button 122 is provided in the second mounting groove 121, and a pressing column is provided in the middle of the second button 122, and the pressing column corresponds to the position of the spring buckle; when the tricycle is in use, the spring buckle is located in the circular hole of the second mounting groove 121. When it is necessary to switch to disassembly of the tricycle, the second button 122 is pressed to move the spring buckle out of the circular hole of the second mounting groove 121, so that the front frame 110 can be moved out of the rear frame 120, thereby realizing the disassembly of the front frame 110 and the rear frame 120.

[0034] Furthermore, in order to facilitate the disassembly of the seat plate 200, a seat plate mounting sleeve 210 is provided at the bottom of the seat plate 200, and third mounting grooves 211 are provided on both sides of the seat plate mounting sleeve 210. A mounting seat 123 is provided above the rear frame 120, and mounting holes are provided on both sides of the mounting seat 123. The third mounting groove 211 is provided with mounting holes corresponding to the mounting holes on the mounting seat 123, and the mounting seat 123 is provided with a spring buckle 124, which can pass through the mounting hole of the mounting seat 123 and enter the mounting hole of the seat plate mounting sleeve 210; the third mounting groove 21 1 is provided with a third button 212, and a pressing column is provided in the middle of the third button 212, and the pressing column corresponds to the position of the spring buckle 124; when the tricycle is in use, the spring buckle 124 is located in the mounting hole of the seat plate mounting sleeve 210. When the seat plate 200 needs to be removed, the third button 212 is pressed to move the spring buckle 124 out of the mounting hole of the seat plate mounting sleeve 210, so that the seat plate mounting sleeve 210 and the seat plate 200 can be removed from above the mounting seat 123 of the rear frame 120, thereby realizing the removal of the seat plate 200 from the rear frame 120.

[0035] Furthermore, in order to facilitate the disassembly of the foot pedal 600, the foot pedal 600 is inserted into the end of the center axis of the front wheel 500 through the polygonal rod 610; and, a foot pedal mounting portion 125 is provided at the bottom of the rear frame 120, and the foot pedal mounting portion 125 is provided with a polygonal hole along the length direction of the rear frame 120. The foot pedal 600 can also be inserted into the polygonal hole of the foot pedal mounting portion 125 through the polygonal rod 610, so that the foot pedal 600 is installed at the bottom of the rear frame 120.

[0036] Furthermore, in order to facilitate parents to push the bicycle, a push rod 900 is connected to the rear frame 120 between the rear wheel fixing frames 140. When the child is tired of riding or encounters difficulties, the parent can hold the push rod 900 to push the bicycle, which is more convenient and safer to use.
