detailed description

The utility model will be further described below in conjunction with the embodiment shown in the accompanying drawings:

As shown in accompanying drawings 1-6, a foldable children's tricycle includes a frame with an unfolded state and a folded state and a locking mechanism for locking the frame in an unfolded state or a folded state, and the frame includes a front wheel The front vehicle frame 1 of 4, the rear vehicle frame 2 that is provided with two rear wheels 5 and the crossbeam 3 that connects front vehicle frame 1 and rear vehicle frame 2, rear vehicle frame 2 is connected with crossbeam 3 rotation, when vehicle frame is folded, rear Vehicle frame 2 rotates close to front vehicle frame 1 direction.

Wherein the front vehicle frame 1 comprises a front strut 11, a front fork 12 arranged at the lower end of the front strut 11 for setting the front wheel 4, a handlebar 13 arranged at the upper end of the front strut 11 and being sleeved on the front strut 11 The outer sleeve 14 is rotatably connected with the front strut 11 , and the sleeve 14 is fixedly connected with the front end of the beam 3 .

The rear vehicle frame 2 includes a rear strut 21 whose upper end is rotatably connected to the crossbeam 3 and whose lower part extends downwards and rearward, and a rear axle 22 horizontally arranged at the lower end of the rear strut 21. The two ends of the rear axle 22 are respectively provided with rear wheels. 5.

The crossbeam 3 is arranged along the front-rear direction of the children's tricycle, and the crossbeam 3 can be used for setting the vehicle seat 6 .

In this embodiment, the rear frame 2 and the beam 3 are arranged to rotate about the rotation axis 71 , and the rotation axis 71 is arranged vertically. Specifically, the rear part of the beam 3 has a first connecting part 72 , and the upper part of the rear frame 2 has a second connecting part 73 , and the first connecting part 72 and the second connecting part 73 are rotatably connected by a rotating shaft 71 .

Referring to FIG. 3 , the locking mechanism includes a locking hole disposed on the first connecting member 72 and a locking pin disposed on the second connecting member 73 . The locking hole and the locking pin can be mutually locked or unlocked, thereby realizing the mutual locking or unlocking of the crossbeam 3 and the rear frame 2 .

In this embodiment, there are two locking holes, which are respectively the locking hole 81a at the rear of the first connecting piece 72 and the locking hole 81b at the front of the first connecting piece 72, and the locking pin and the locking hole 81a, the locking hole 81b The locked state corresponds to the unfolded state and the folded state of the vehicle frame respectively.

The lock pin includes a body 82 slidably disposed in a chute on the second connector 73 , a handle 83 disposed on the side of the body 82 and protruding from the surface of the second connector 73 , and a spring 84 that pushes the body 82 to slide toward the locking hole 81 .

When the children's tricycle is unfolded, the locking pin is locked with the locking hole 81a. When the children's tricycle needs to be folded, the handle 83 of the locking pin is pulled down to make the locking pin break away from the locking hole 81a, and then rotate along the rotating shaft 71 Frame 2, so that the rear frame 2 is horizontally rotated 180 degrees relative to the front frame 1, and is close to the front frame 1. When the front end of the lock pin is facing the locking hole 81b, the handle 83 of the lock pin is released, and the lock pin is on the spring. 84 is locked with the locking hole 81b, and the children's tricycle is in a folded state. At this time, the rear wheel frame 2 is located below the crossbeam 3, and is also located between the front wheel frame 1 and the seat 6, thereby reducing the front and rear length of the frame. space taken up.

When it is necessary to restore the children's tricycle to the unfolded state, pull the handle 83 of the lock pin, so that the lock pin breaks away from the lock hole 81b, and then rotate the rear frame 2 along the rotating shaft 71, so that the rear frame 2 is far away from the front frame 1 , when the front end of the lock pin is facing the lock hole 81a, the handle 83 of the lock pin is released, the lock pin is locked with the lock hole 81a under the action of the spring 84, and the children's tricycle returns to the unfolded state.

The children's tricycle of this embodiment is easy to fold and unfold, and can reduce the storage volume of the children's tricycle without dismantling the frame, so as to meet the daily storage volume requirements of the children's tricycle.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
