[0002] Remote-controlled toy cars are remote-controlled toys designed specifically for children, combining car models with remote control technology, allowing children to remotely control the car's movement. These toys are usually equipped with lighting and sound systems, increasing the realism and fun of playing. Remote-controlled toy cars not only provide a rich entertainment experience but also help develop children's fine motor skills and coordination.
[0003] To improve the ability of remote-controlled cars to traverse complex terrains and roads, a four-wheel drive omnidirectional toy remote-controlled car with a drive shaft is needed.

Steering mechanisms can be installed on the front wheels to guide the car. As a result, current toy remote control cars have relatively weak wheel power, making them prone to getting stuck on complex terrain and unable to move forward. They also have a large turning radius, making it impossible to pass through some curves. To address these issues, a four-wheel drive omnidirectional toy remote control car with a drive shaft is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0035] Reference Figure 1 - Figure 3This utility model provides an embodiment of a four-wheel drive omnidirectional remote control toy car with a drive shaft, including a chassis 1 for fixing and supporting equipment. A power component is fixedly connected inside the chassis 1. The power component includes a power bracket 2 that provides fixed support. Both ends of the power bracket 2 are fixedly connected inside the chassis 1. A motor 3 that provides forward power to the vehicle is fixedly connected inside the power bracket 2. Inner universal joints 4 are provided at both ends of the power component. The inner universal joints 4 can transmit power and torque between different angles. The inner side of the inner universal joint 4 is fixedly connected to the output shafts at both ends of the motor 3. A drive shaft 5 is fixedly connected to the outer side of the inner universal joint 4. The inner universal joint 4 transmits the rotational power of the motor 3 to the drive shaft 5. An outer universal joint 6 is fixedly connected to the outer side of the drive shaft 5. The outer universal joint 6 can transmit power and torque between different angles. A drive bevel gear 7 is fixedly connected to the outer side of the outer universal joint 6. The outer universal joint 6 transmits the power of the drive shaft 5 to the drive bevel gear 7. A transmission bevel gear 8 meshes with the outer side of the drive bevel gear 7. A rotating shaft 9 is fixedly connected inside the transmission bevel gear 8.
[0036] Reference Figure 1 - Figure 2 Wheels 10 are fixedly connected to both ends of the rotating shaft 9. A gearbox 11, which provides fixed support, is rotatably connected to the outer circumference of the rotating shaft 9. An outer universal joint 6 passes through the outer circumference and is rotatably connected to the inner side of the gearbox 11. The outer end of the outer universal joint 6 is positioned to ensure that the driving bevel gear 7 always meshes with the transmission bevel gear 8. A steering bracket 12, which provides fixed support, is rotatably connected to the outer circumference of the rotating shaft 9. The top of the gearbox 11 is fixedly connected to the inner wall of the top of the steering bracket 12, which provides fixed support. A steering link 13 is hinged to the bottom surface of the steering bracket 12, connecting the left and right sets of steering brackets 12. The steering link 13 is also designed with... The two sets of steering brackets 12 are positioned diagonally opposite each other. When one steering bracket 12 rotates, the other steering bracket 12 rotates in the opposite direction through the steering linkage 13. A rotating column 14 is fixedly connected to the top of the right steering bracket 12. The top of the rotating column 14 is rotatably connected to the bottom of the chassis 1, causing the right steering bracket 12 to rotate around the center of the rotating column 14. A steering column 15 is fixedly connected to the top of the left steering bracket 12. The left steering bracket 12 rotates around the center of the steering column 15. The outer circumference of the steering column 15 is rotatably connected to the inside of the chassis 1. A rotating assembly is fixedly connected to the outer circumference of the steering column 15. The rotating assembly is used to drive the steering column 15 to rotate.
[0037] Reference Figure 1 and Figure 4The rotating assembly includes a worm gear 16, with a worm 17 meshing on its front. The rotation between the worm 17 and the worm gear 16 is relatively large; the worm gear 16 rotates only once for the worm 17 to rotate multiple times. A rotating bracket 18, which provides fixed support, is rotatably connected to the outer periphery of the worm 17. The bottom of the rotating bracket 18 is fixedly connected to the top of the chassis 1. A rotating motor 20, which provides rotational power, is located on the right side of the worm 17. The right side of the worm 17 is fixedly connected to the left output shaft of the rotating motor 20. When the rotating motor 20 is turned on, the left output shaft of the rotating motor 20 will drive the worm 17 to rotate. A motor bracket 19, which provides fixed support, is fixedly connected to the bottom of the rotating motor 20. The bottom of the motor bracket 19 is fixedly connected to the top of the chassis 1.
[0038] Working principle: When you want the toy car to cross complex terrain and roads, turn on motor 3. The output shafts on both sides of motor 3 will drive the inner universal joints 4 on both sides to rotate. The inner universal joints 4 will drive the transmission shaft 5 to rotate. The transmission shaft 5 will drive the outer universal joint 6 to rotate. The outer universal joint 6 will drive the drive bevel gear 7 to rotate. The drive bevel gear 7 will drive the transmission bevel gear 8 to rotate. The transmission bevel gear 8 will drive the rotating shaft 9 to rotate. At this time, the two sets of rotating shafts 9 on the left and right sides will drive the four sets of wheels 10 to rotate simultaneously, increasing the power of the toy car. At the same time, the rotating components will drive the steering column 15 to rotate. The steering column 15 will drive the left steering bracket 12 to rotate. The left steering bracket 12 will drive the right steering bracket 12 to rotate in the opposite direction through the steering linkage 13, so that the rear wheels 10 will assist in steering at the same time, reducing the turning radius of the toy car, thereby improving the toy car's ability to cross complex terrain and roads. When you want to steer the toy car, turn on the rotating motor 20. The rotating motor 20 drives the worm gear 17 to rotate, the worm gear 17 drives the worm wheel 16 to rotate, the worm wheel 16 drives the steering column 15 to rotate, and the steering column 15 drives the left steering bracket 12 to rotate. The rotation of the worm wheel 16 and the worm gear 17 increases the steering accuracy.
