[0024] An installation cavity is provided between the chassis 1 and the bottom cover 14. The installation cavity is located in the middle of the whole toy car. A first magnetic charging device 4, a charging socket 5, a switch 6, a drive motor 8 and a steering motor 9 are provided in the installation cavity; the solder feet of the first magnetic charging device 4, the charging socket 5, the switch 6, the drive motor 8 and the steering motor 9 all pass through the chassis 1 and are electrically connected to the circuit board 3. The operation surfaces of the first magnetic charging device 4, the charging socket 5 and the switch 6 pass through the bottom cover 14 and are arranged on the outer surface of the bottom cover 14, that is, the bottom of the toy car, so as to facilitate use.

[0025] The steering motor 9 is connected to the front wheel assembly 15 of the toy car through a gear transmission to achieve a steering effect. The front wheel assembly 15 includes two bogies. The two bogies are respectively hinged on both sides of the bottom surface of the chassis 1. In any one of the bogies, a front wheel is respectively connected through a wheel axle and a bearing structure. Any one of the bogies is fixedly connected with a rocker. A sector-shaped steering gear is hinged in the middle of the bottom surface of the chassis 1. The sector-shaped steering gear is hinged to the middle of a connecting rod at an eccentric position. Both ends of the connecting rod are respectively hinged to one end of a rocker. The output shaft of the steering motor 9 is connected to a steering worm through a spur gear transmission. The sector-shaped steering gear is in tooth connection with the steering worm. This transmission structure is a common mechanical transmission steering structure in the prior art and will not be elaborated here.

[0026] A driving motor 8 and a rear wheel assembly 10 are provided on the chassis 1. The driving motor 8 is connected to the rear wheel assembly 10 of the toy car through a plurality of reduction gears. Specifically, the rear wheel assembly 10 includes a rear wheel shaft 1005, a first spur gear 1001, a first reduction gear 1002, a second reduction gear 1003 and a second spur gear 1004.

[0027] A second magnetic charging device 11 is provided on the remote control 12, and the second magnetic charging device 11 is magnetically connected to the first magnetic charging device 4. Specifically, a first contact 402 and a pair of first magnets 401 are provided on the first magnetic charging device 4, and a second contact 1102 and a pair of second magnets 1101 are provided on the second magnetic charging device 11.

[0028] After the charging socket 5 is electrically connected to the circuit board 3, it can also be electrically connected to the lithium battery through the charging module on the circuit board 3, thereby realizing the effect of charging the lithium battery through the charging socket 5. When the first magnetic charging device 4 and the second magnetic charging device 11 are charging, the charging socket 5 will be blocked by the remote control 12 and cannot be charged at the same time, thereby avoiding the conflict of charging the magnetic charging device 11 and the charging socket 5 at the same time.

[0029] A reset button 7 is also provided in the installation cavity. The reset button 7 is arranged beside the charging socket 5. The solder legs of the reset button 7 pass through the chassis 1 and are electrically connected to the 2.4G wireless module on the circuit board 3, so as to achieve the effect of resetting the connection between the toy car and the remote control 12 by pressing the reset button 7.
