Description

Technical Field

[0001] The utility model relates to a toy, in particular to a novel toy stunt car. Background Art

[0002] A toy stunt car is a vehicle capable of performing cool maneuvers and stunts. It typically features special structures or functions that allow for gameplay not possible with ordinary toy cars. During play, the toy car can be manipulated using a handle to perform stunts such as changing the length of the vehicle and lifting the front wheels. Most toy stunt cars utilize a design in which two motors control each of the two rear wheels. These motors achieve turns and U-turns by controlling the differential rotation of the two rear wheels, and each motor requires a corresponding reduction gear set. Most existing toy stunt cars simply mount the motor and several gears directly to the chassis. The excessive number of components within the chassis increases the difficulty of assembly and disassembly. To address this issue, we have proposed a new type of toy stunt car. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Combined with attachment Figure 1 To the attached Figure 3 As shown, a novel toy stunt vehicle includes a front body 10 and a rear body 20, which are movably hinged. The front body 10 is provided with front wheels 30, and the rear body 20 is provided with rear wheels 40. A dual rear-wheel drive mechanism 50 is provided within the rear body 20. The dual rear-wheel drive mechanism 50 can drive the two rear wheels 40 separately, enabling the toy stunt vehicle to turn and make U-turns.

[0025] Combined with attachment Figure 6 To the attached Figure 9 As shown, the dual rear-wheel drive mechanism 50 includes a mounting frame 51. Motor mounting openings 511 are defined on both sides of the mounting frame 51. Each motor mounting opening 511 houses a drive motor 52. The mounting frame 51 is provided with axle holes 513 extending through both sides. Rear-wheel drive shafts 53 are inserted into the left and right ends of the axle holes 513. The mounting frame 51 is provided with wing panels 514 for connection to the rear vehicle body 20. Several ribs 515 are provided within the motor mounting openings 511 to securely support the drive motors 52.

[0026] Each drive motor 52 is provided with a corresponding transmission gear set 54, which specifically functions as a speed reducer. The transmission gear set 54 is mounted on the outside of the end plate 512 of the motor mounting opening 511. The two drive motors 52 each drive the corresponding rear wheel 40 via the rear wheel drive shaft 53.

[0027] Combined with attachment Figure 7As shown, an end cover 55 is provided on the outer side of the end plate 512 of the motor mounting opening 511 for covering the transmission gear set 54. The transmission gear set 54 includes a driving gear 541, a first transmission gear 542, a second transmission gear 543, and a driven gear 544. The driving gear 541 is mounted on the output shaft of the drive motor 52, the first transmission gear 542 is meshed with the driving gear 541, the second transmission gear 543 and the second transmission gear 543 share the same gear shaft 545, the second transmission gear 543 is meshed with the driven gear 544, and the driven gear 544 is mounted on the rear wheel drive shaft 53.

[0028] When driving the rear wheel 40 to rotate, the output shaft of the drive motor 52 drives the driving gear 541 to rotate, the driving gear 541 drives the first transmission gear 542, the first transmission gear 542 drives the second transmission gear 543 to rotate synchronously through the gear shaft 545, the second transmission gear 543 drives the driven gear 544, and the driven gear 544 then drives the rear wheel 40 to rotate through the rear wheel drive shaft 53.

[0029] The present invention integrates the left and right drive motors 52 and the transmission gear set 54 into the dual rear-wheel drive mechanism 50. Compared with the existing toy stunt cars, the present invention adopts the structural design of the dual rear-wheel drive mechanism 50, which can be removed from the base 21, significantly reducing the difficulty of disassembly and assembly, and facilitating the maintenance and replacement of parts at the base.

[0030] The front body 10 includes a front wheel frame 11 and a body cover 12, which is arranged on the upper side of the front wheel frame 11. The rear body 20 includes a base 21 and an upper cover 22, the base 21 is provided with an articulated buckle 211 for articulating with the front body 10, and the upper cover 22 is provided with a supporting roller 221.

[0031] As attached Figure 4 As shown in FIG, the toy stunt car can change the length of the body by adjusting the wheelbase between the front wheels and the rear wheels, thereby being able to perform body shortening and deformation stunts. Figure 5 As shown, the toy stunt car can also lift the front wheels, and directly contact the ground with the rear wheels and the supporting rollers 221, so that the whole car can be moved in a stunt with the front wheels lifted.
