Description

Technical Field

[0001] This invention relates to the field of remote-controlled vehicles, and particularly to an adjustable omnidirectional steering mechanism for a toy remote-controlled vehicle. Background Technology

[0002] Remote control cars, as everyday toys for children, are popular with boys of all ages due to their high entertainment value and attractive appearance. However, existing remote control cars have relatively small steering gearboxes, typically only allowing the wheels to rotate 18-25°, making steering cumbersome and resulting in a large turning radius. Recently, remote control cars with increased wheel rotation angles have emerged, such as the remote control toy car with improved steering control disclosed in publication number CN204121749U on January 28, 2015. This car includes a body, front and rear wheels, and a steering mechanism. Its steering mechanism features a gearbox, a lateral linkage assembly connecting the two front wheels and enabling them to steer, a steering motor, a gear transmission group, a toggle element, and a rotary potentiometer. The toggle element is an L-shaped angle lever integrally formed on one side of the output gear in the aforementioned transmission gear group, and a toggle post integrally formed with the angle lever and perpendicular to its moving surface. The toggle post is slidably connected to the lateral linkage assembly. In this type of remote control car, the wheel steering angle can reach a maximum of approximately 45°. However, this steering angle still cannot make the remote-controlled car fully adjustable, and it has a complex structure and occupies a large space in the vehicle body. At present, some remote-controlled cars use multiple motors to drive each wheel separately, thereby achieving steering by controlling the differential speed of each wheel. However, this method requires controlling each wheel motor at the same time, making it difficult to make fine adjustments to the steering angle. It is only convenient for extreme angle adjustments (such as using differential speed to make the remote-controlled car rotate in place or move sideways). Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an adjustable universal steering mechanism for a toy remote control car. This adjustable universal steering mechanism can turn the front wheels and the rear wheels at various angles, thereby allowing the remote control car to be controlled at will. It has a simple structure and is easy to adjust and control.

[0004] To solve the above technical problems, the following technical solution is adopted:

[0005] An adjustable omnidirectional steering mechanism for a toy remote-controlled car is characterized by comprising a first steering device and a second steering device, both of which include a steering drive device, a rocker arm, a connecting rod, at least one rotating component, and at least one wheel bracket; one end of the rocker arm is connected to the power output end of the steering drive device, and the other end of the rocker arm is hinged to the middle of the connecting rod; the number of rotating components and wheel brackets are the same and correspond one-to-one, the rotating components are rotatably mounted on the body of the toy remote-controlled car, the rotating components are hinged to the connecting rod, and the hinge position is offset from the rotation center of the rotating components; the upper end of the wheel bracket is fixedly connected to the rotating component.

[0006] In the aforementioned adjustable omnidirectional steering mechanism, the first steering device and the second steering device respectively control the steering of the front and rear wheels on the remote-controlled vehicle. The lower or upper end of the wheel bracket is used to connect with the corresponding wheel. The rotating component is rotatably mounted on the vehicle body, and the rotating component's rotation center is the connection position between the wheel bracket and the rotating component. During control, the steering drive device drives the linkage to move left and right. During the left and right movement, the linkage also moves back and forth. The angle between the rotating component and the linkage hinge position changes accordingly. Therefore, pushing the rotating component to rotate causes the wheel bracket to rotate, thereby achieving simultaneous rotation of the wheels on the same side. This adjustable omnidirectional steering mechanism, by setting a first steering device and a second steering device, can drive the front and rear wheels or the left and right wheels respectively. The rotating component is not directly connected to the wheel, but is connected through a wheel bracket. Therefore, the rotating component and the connecting rod can be set above or below the wheel, offset from the wheel, which can effectively avoid the movement of the connecting rod and the rotating component being restricted by the position of the wheel. Theoretically, the rotation angle of the rotating component can reach 360°. In practical applications, it is only necessary to make the rotation angle of the rotating component reach 180°. Even if the wheel turns to the left or right, the angle can reach 90°. With the combined steering of the first steering device and the second steering device, the remote control car can be turned at various angles. Moreover, the steering angle can be finely adjusted as needed, and the adjustment is convenient. Therefore, by using the first steering device and the second steering device to control the steering of the front and rear wheels respectively, the omnidirectional adjustable steering of the remote control car can be successfully achieved.

[0007] In a preferred embodiment, the distance between the hinge position of the rotating component and the connecting rod and the rotation center of the rotating component is the same as the length of the swing rod.

[0008] In a preferred embodiment, the rotating component is provided with an eccentric hole, and the connecting rod is provided with a pin. The pin is inserted into the eccentric hole, and the rotating component and the connecting rod are hinged through the eccentric hole and the pin.

[0009] In a further preferred embodiment, the rotating component is a rotating wheel, and the eccentric hole is located away from the rotation center of the rotating wheel. The rotating wheel is rotatably mounted on the vehicle body.

[0010] In another further preferred embodiment, the rotating component is a swing arm, which has a swing end and a fixed end. The fixed end of the swing arm is fixedly connected to the wheel bracket, and the eccentric hole is formed on the swing end of the swing arm. The swing arm is rotatably connected to the body of the remote-controlled car through the fixed end.

[0011] In a further preferred embodiment, the number of rotating parts is two, and the two ends of the connecting rod are respectively hinged to the eccentric holes of the two rotating parts.

[0012] In a preferred embodiment, the steering drive device is a servo motor or a steering gear, and the rocker arm is connected to the output shaft of the servo motor or steering gear. The steering drive device uses a common servo motor or steering gear, and during control, it operates in the same way as a typical remote-controlled car, allowing for easy adjustment of the steering angle as needed.

[0013] The beneficial effects of this invention are as follows: this adjustable universal steering mechanism can turn the front wheels and rear wheels at various angles, thereby allowing for free control of the remote control car's direction of travel. It has a simple structure and is easy to adjust and control. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] like Figure 1 The adjustable omnidirectional steering mechanism of a toy remote control car shown includes a first steering device and a second steering device. Both the first and second steering devices include a steering drive device 1, a rocker arm 2, a connecting rod 3, two rotating parts 4, and two wheel brackets 5. One end of the rocker arm 2 is connected to the power output end of the steering drive device 1, and the other end of the rocker arm 2 is hinged to the middle of the connecting rod 3. The number of rotating parts 4 and wheel brackets 5 are the same and they correspond one-to-one. The rotating parts 4 are rotatably mounted on the body of the toy remote control car. Both ends of the connecting rod 3 are respectively hinged to the two rotating parts 4, and the hinge positions are offset from the rotation center of the rotating parts 4. The upper end of the wheel bracket 5 is fixedly connected to the rotating parts 4.

[0019] In the aforementioned adjustable omnidirectional steering mechanism, the first steering device and the second steering device respectively control the steering of the front and rear wheels on the remote-controlled vehicle. The lower or upper end of the wheel bracket 5 is used to connect with the corresponding wheel. The rotating component 4 is rotatably mounted on the vehicle body, and the rotating component 4 has its rotation center at the connection position between the wheel bracket 5 and the rotating component 4. During control, the steering drive device 1 drives the linkage 3 to move left and right. During the left and right movement, the linkage 3 also moves back and forth. The angle between the hinge position of the rotating component 4 and the linkage 3 changes accordingly. Therefore, pushing the rotating component 4 to rotate causes the wheel bracket 5 to rotate, thereby achieving simultaneous rotation of the wheels on the same side. This adjustable omnidirectional steering mechanism, by setting a first steering device and a second steering device, can drive the front and rear wheels or the left and right wheels respectively. The rotating part 4 is not directly connected to the wheel, but is connected through the wheel bracket 5. Therefore, the rotating part 4 and the connecting rod 3 can be set above or below the wheel, offset from the wheel, which can effectively avoid the movement of the connecting rod 3 and the rotating part 4 being restricted by the position of the wheel. Theoretically, the rotation angle of the rotating part 4 can reach 360°. In practical applications, it is only necessary to make the rotation angle of the rotating part 4 reach 180°. Even if the wheel turns to the left or right, the angle can reach 90°. With the combined steering of the first steering device and the second steering device, the remote control car can be turned at various angles. Moreover, the steering angle can be finely adjusted as needed, which is convenient. Therefore, when the first steering device and the second steering device are used to control the steering of the front and rear wheels respectively, the omnidirectional adjustable steering of the remote control car can be successfully realized.

[0020] In the rotating component 4, the distance between the hinge position of the rotating component 4 and the connecting rod 3 and the rotation center of the rotating component 4 is the same as the length of the swing rod 2.

[0021] The rotating part 4 is provided with an eccentric hole, and the connecting rod 3 is provided with a pin. The pin is inserted into the eccentric hole, and the rotating part 4 and the connecting rod 3 are hinged through the eccentric hole and the pin.

[0022] Rotating component 4 is a rotating wheel, with an eccentric hole positioned away from the rotation center of the rotating wheel. The rotating wheel is rotatably mounted on the vehicle body.

[0023] Steering drive device 1 is a servo motor, and rocker arm 2 is connected to the output shaft of the servo motor.

[0024] Example 2

[0025] The difference between this embodiment and Embodiment 1 is that: Figure 2 As shown, the wheel bracket 5' in this embodiment has a different shape than the wheel bracket in embodiment 1.
