Hereinafter, the drifting mode of the utility model of the child toy car will be described by taking the case of turning the handle bar 62 to the right:

referring to fig. 5 to 7, when the user turns the handle lever 62 to the right, the steering base 1 and the front wheel a0 are synchronously turned to the right.

Thereafter, referring to fig. 6 to 8, due to inertia, the front wheel base 2 and the rear wheel base 4 gradually rotate leftward around the first rotation axis a in synchronization, in the process, the limit shaft 25 gradually slides backward along the length direction of the limit groove 31A until the limit shaft 25 abuts against the rear end portion of the limit groove 31A, the limit shaft 25 is located at the left braking position, and the rotation of the front wheel base 2 and the rear wheel base 4 leftward in synchronization is stopped.

Then, referring to fig. 9, due to inertia, the rear wheel seat 4 gradually rotates to the left around the second rotation axis b, the rear rail 41A located at the left side of the child toy car gradually approaches the front rail 21 at the same side, and simultaneously, the restoring member 5 is gradually extended. In this process, the reset member 5 applies negative work to the rear wheel seat 4, so that the rate of the left rotation of the rear wheel seat 4 is continuously reduced until the rate is reduced to zero or the rear side surrounding rod 41A on the left side and the front surrounding rod 21 on the same side are braked by abutting, and then the reset member 5 applies positive work to the rear wheel seat 4. Referring to fig. 10 and 11, the restoring member 5 drives the rear wheel seat 4 to rotate gradually to the right around the second rotation axis b, and the length of the restoring member 5 is gradually shortened in the process. Rotation to the rear wheel seat 4 causes the rear support bar 43 to be parallel to the front support bar 22 and the return element 5 to stop doing work. At this time, as shown in fig. 12 and 13, due to inertia, the front wheel base 2 and the rear wheel base 4 gradually rotate rightward around the first rotation axis a in synchronization, the stopper shaft 25 gradually slides forward along the length direction of the stopper groove 31A until the stopper shaft 25 abuts against the front end portion of the stopper groove 31A, the stopper shaft 25 is positioned at the right braking position, and the synchronous rightward rotation of the front wheel base 2 and the rear wheel base 4 is stopped.

Then, referring to fig. 13, due to inertia, the rear wheel seat 4 gradually rotates to the right around the second rotation axis b, the rear surrounding rod 41A on the right side of the child toy car gradually approaches the front surrounding rod 21 on the same side, and simultaneously, the restoring member 5 is gradually lengthened, and in the process, the restoring member 5 applies negative work to the rear wheel seat 4, so that the rate of the right rotation of the rear wheel seat 4 continuously decreases. After this rate has been reduced to zero or the rear shroud bar 41A on the right has been braked by abutment against the same front shroud bar 21, the return element 5 in turn applies positive work to the rear wheel carrier 4. Referring to fig. 14, the reset member 5 drives the rear wheel holder 4 to gradually rotate leftward about the second rotation axis b.

The process is repeated, and the toy car for children makes reciprocating swing motion in the left and right directions, so that the drifting effect is realized. It should be noted that, the drifting mode of the children's toy car of the present invention is specifically described herein only by turning the handle bar 62 to the right, and the user can achieve the drifting effect by turning the handle bar 62 to the left or to the right, and both of the above manners are included in the scope of the present invention.

In the embodiment, the children's toy car can also be converted to the existing drifting mode to work, and the following steps are specifically carried out:

the child toy car further includes a locking pin (not shown), and as shown in fig. 4, the upper connection piece is further provided with an upper limiting hole 24B, the upper limiting hole 24B extends in the up-down direction and is located at the rear side of the through hole 24A, the rear support rod 43 is provided with a lower limiting hole 43A, the lower limiting hole 43A extends in the up-down direction, and the lower limiting hole 43A can be positioned opposite to the upper limiting hole 24B by adjusting the relative position between the rear wheel seat 4 and the front wheel seat 2. When the child toy car is converted to the existing drifting mode, the relative position between the rear wheel seat 4 and the front wheel seat 2 is adjusted to enable the upper limiting hole 24B to be opposite to the lower limiting hole 43A, and then the locking pin (shown in the figure) is inserted between the upper limiting hole 24B and the lower limiting hole 43A in a matched mode. The rear wheel carrier 4 is connected in a relatively fixed manner to the front wheel carrier 2 by the joint action of the connecting pin 45 and the locking pin (shown in the figure). In this case, the rear wheel seat 4 and the front wheel seat 2 are fixedly connected to each other, and the front stay 22 and the rear stay 43 extend in parallel or substantially in the same longitudinal direction.

The arrangement improves the practicability of the toy car for children. The guardian of the child can convert the child toy car into a drifting mode in which the child is interested, and the conversion operation is simple; thanks to the above conversion being accomplished simply and quickly, some children may also switch the children's toy vehicle to the interesting excursion mode for play by themselves.

In conclusion, the toy car for children can achieve the drifting effect, entertainment and interestingness of the four-wheel drifting car. In addition, the child toy car of the present invention is provided with the steering stopper mechanism 3 to prevent collision between the front side rail 21 and the front wheel a0, so that the child toy car of the present invention also has high safety.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
