Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A folding tricycle in this embodiment includes a front support 101, a handlebar 102 fixedly mounted on the top of the front support 101, a front wheel 103 installed inside the front support 101, foot pedals 104 mounted on the left and right sides of the front support 101 and on the surface of the front wheel 103, a front fork 105 welded to one side of the front support 101, a connecting seat 106 connected to the side of the front fork 105 away from the front support 101, a seat 107 fixedly mounted on the top of the connecting seat 106, a rear frame 108 rotatably mounted on the end of the connecting seat 106 away from the front fork 105, a storage basket 109 mounted on one end of the rear frame 108, and rear wheels 110 fixedly mounted on both sides of the surface of the rear frame 108 on the storage basket 109.

[0024] In this embodiment, the tricycle consists of a front support 101 with a handlebar 102 fixed to its top and a front wheel 103 installed inside. There are foot pedals 104 on the left and right sides. The front fork 105 is welded to one side of the front support 101, and the other side of the front fork 105 is connected to a connecting seat 106. The top of the connecting seat is a seat 107, and the other end of the connecting seat is rotatably mounted to a rear frame 108. The rear frame 108 has a storage basket 109 at one end and rear wheels 110 on both sides.

[0025] Meanwhile, all components work together to provide stable riding support; the handlebar 102 makes it easy for children to hold and control the direction, ensuring riding safety; the foot pedal 104 provides a pedaling assist position for children; the seat 107 provides a comfortable seating position; the storage basket 109 can hold children's small items, increasing practicality; the rotatable rear rack 108, together with the folding component 2, enables the vehicle to have a folding function, making it easy to store and carry, saving space and improving ease of use.

[0026] The connecting base 106 has a folding component 2 installed inside;

[0027] The folding assembly 2 includes a connecting plate 201 installed between the top of the connecting seat 106 and the seat 107. The connecting seat 106 includes a first arc plate 202 and a second arc plate 203 installed at the front and rear ends of the connecting plate 201, respectively. A pressing key 204 is movably installed inside the first arc plate 202. A connecting plate 205 is fixedly installed on the side of the pressing key 204 away from the first arc plate 202. A connector 206 is installed on the end of the connecting plate 205 away from the pressing key 204. A rotating shaft 207 is rotatably installed inside the connecting plate 201. A connecting block 209 is fixed inside the second arc plate 203. Two small parts 208 are installed inside the connecting block 209. Two limiting holes 210 are opened inside the connecting plate 201 and on the side of the rotating shaft 207.

[0028] A return spring is fixedly installed between the two small parts 208. The two limit holes 210 are arc-shaped and adapted to the small parts 208. The pressing key 204 and the connecting plate 205 are integrally formed. The outer surface of the pressing key 204 is provided with anti-slip texture. Wear-resistant bushings are provided at the rotational connection points between the two ends of the rotating shaft 207 and the connecting seat plate 201. The rear frame 108 is rotatably connected to the connecting seat 106 through the rotating shaft 207.

[0029] In this embodiment, when folded, normally, the return spring provides elastic force to the two small parts 208, keeping them in the pop-out state. The small parts 208 abut against relevant structures such as the limiting hole 210, keeping the tricycle in the unfolded state and ensuring structural stability during riding.

[0030] When folding is required, press the press button 204 with anti-slip texture. Since the press button 204 is integrally formed with the connecting plate 205, its movement drives the connecting plate 205, which in turn causes the column associated with the connecting piece 206 to move. The column squeezes the small piece 208, causing it to overcome the spring force and be pressed back into the connecting block 209, disengaging from the limiting hole 210 and releasing the restriction on the folding part. At this time, the rear frame 108 plays a role through the rotational connection structure between the rotating shaft 207 and the connecting seat 106. The three-wheeled components can rotate and fold around the rotating shaft 207. After rotating to the predetermined position, the structure automatically locks.

[0031] Press the button 204 again to repeat the above linkage process to unlock. The small part 208 pops out under the action of the reset spring and re-locks into the limit hole 210. The three-wheel component returns to the unfolded state. The wear-resistant bushing can reduce the wear of the rotating shaft 207 when it rotates and extend the service life of the folding component 2.

[0032] In summary, this folding tricycle, through the linkage structure of the press button 204, connecting plate 205, and connecting piece 206 within the folding assembly 2, combined with the small piece 208 with a return spring and the limiting hole 210, achieves an easy press-to-fold and press-to-unfold operation. When unfolded, the small piece 208 presses against the limiting hole 210 under the spring force, ensuring a stable connection of components such as the rear frame 108 and guaranteeing riding stability. When folded, the press button 204 drives the component to squeeze the small piece 208 to retract it, releasing the restriction. The rear frame 108 can then be folded around the rotation axis 207 for easy storage and carrying, saving space.

[0033] Furthermore, the anti-slip texture design on the outer surface of the press button 204 enhances the stability and comfort of the pressing operation; the integrated structure of the press button 204 and the connecting plate 205 strengthens the component; at the same time, the wear-resistant bushings installed at both ends of the rotating shaft 207 effectively reduce wear during rotation and extend the service life of the folding assembly 2; the reasonable assembly of components such as the front bracket 101, front fork 105, and connecting seat 106, together with the armrest 102, foot pedals 104, and seat 107, provides a stable and safe riding support environment for children.
