Embodiment I

As shown in FIGS. 1-8, one embodiment of the a remote-controlled toy vehicle with omnidirectional adjustable steering comprises:

- a vehicle body 1 having a remote control receiving circuit;
- a remote control device (not shown) capable of communicating with the remote control receiving circuit;
- at least one steering means 201, 202 mounted on the vehicle body 1; and
- a plurality of wheels 3, 4;
- wherein each steering means 201, 202 comprises a steering drive means 2121, a pivot rod 2122, a connecting rod 2123, at least one swivelable member 2124, and at least one wheel bracket 2125, with the number of swivelable members 2124 and the number of wheel brackets 2125 in the steering means 201, 202 being the same as the number of the wheels 3, 4 connected to the steering means 201, 202;
- wherein in each steering means 201, 202, the pivot rod 2122 is connected at a first end to a power output end of the steering drive means 2121 and hinged at a second end to a middle of the connecting rod 2123;
- wherein each swivelable member 2124 is swivelably mounted on the vehicle body 1 and hinged to the connecting rod 2123 at a hinge position offset from a swivel center of the swivelable member 2124;
- wherein each wheel bracket 2125 is fixedly connected at an upper end to the swivelable member 2124 and hinged at a lower end to a corresponding wheel 3, 4; and
- wherein at least one wheel 3 at a front of the vehicle is independently driven from at least one wheel 4 at a rear of the vehicle.

In one embodiment of the above remote-controlled toy vehicle with omnidirectional adjustable steering, a front steering means 201 and a rear steering means 202 control steering of a front wheel 3 and a rear wheel 4, respectively, while the swivelable member 2124 positions its swivel center at a connection point with the wheel bracket 2125.

During a steering control, the steering drive means 2121 maneuver the connecting rod 2123 laterally. This lateral movement of the connecting rod 2123 also causes the connecting rod 2123 to move forward and backward, thereby changing an angular position of the hinge between the swivelable member 2124 and the connecting rod 2123, with respect to the swivel center of the swivelable member 2124. As a result, the movement of the connecting rod 2123 induces the swivelable member 2124 to swivel, leading to the swivel of the corresponding wheel brackets 2125, thereby enabling simultaneous swivel of the direction of all corresponding wheels 3, 4.

With such a steering mechanism 2 in the above remote-controlled toy vehicle with omnidirectional adjustable steering, a front steering means 201 and a rear steering means 202 can be implemented to independently drive front wheels and rear wheels respectively, or to independently drive left wheels and right wheels respectively.

Moreover, since the swivelable member 2124 is linked to a wheel via the wheel bracket 2125 rather than directly, the swivelable member 2124 and connecting rod 2123 can be positioned above or below a wheel, as well as offset from the wheel, thereby effectively circumvents constraints imposed by the wheel's position on the movement of the connecting rod 2123 and swivelable member 2124, theoretically enabling the swivelable member 2124 to swivel 360° (It should be noted that, in practical application, swiveling the swivelable member 2124 to 180° is sufficient, resulting in a wheel turning angle of 90° to both the left and right).

Under the combined steering of the front steering means 201 and rear steering means 202, the remote-controlled vehicle can achieve steering at various angles, and the steering angle can be finely adjusted as needed, making adjustment convenient.

Therefore, when using the front steering means 201 and rear steering means 202 to independently control steering of the front wheels and rear wheels 4 respectively, seamless omnidirectional steering of the remote-controlled vehicle can be achieved.

In the swivelable member 2124, a distance from the swivel center of the swivelable member 2124 to the hinge position of the swivelable member 2124, where the swivelable member 2124 is hinged to the connecting rod 2123, equals a length of the pivot rod 2122.

In each steering means, each swivelable member 2124 is provided with an eccentric hole, and the connecting rod 2123 is provided with a pin shaft capable of being inserted into the eccentric hole to hinge the swivelable member 2124 and the connecting rod 2123 together.

In each steering means, each swivelable member 2124 is a swivelable cylinder swivelably mounted on the vehicle body 1, and the eccentric hole is provided at a position offset from the swivel center of the swivelable cylinder.

In each steering means, the steering drive means 2121 is a servo drive, and the pivot rod 2122 is connected to an output shaft of the servo drive.

The steering drive means 2121 adopts a commonly seen servo drive, and during steering control, it operates similarly to typical remote-controlled vehicle steering mechanisms, enabling convenient adjustment of the steering angle as required.

One embodiment of the remote-controlled toy vehicle with omnidirectional adjustable steering further comprises a plurality of wheel drive means 5, with the number of the plurality of wheel drive means 5 being the same as the number of the plurality of wheels 3, 4; each of the plurality of wheels 3, 4, together with the corresponding wheel bracket 2125, form a first-type wheel-unit structure having a first inner cavity for accommodating a corresponding wheel drive means 5 and allowing a main body of the corresponding wheel drive means 5 to be mounted within the wheel bracket 2125; and each of the plurality of wheel drive means 5 is provided with a first mounting shaft 501, enabling each of the plurality of wheels 3, 4 to be rotatably sleeved onto the first mounting shaft 501 to establish a transmission connection with the power output end of the corresponding wheel drive means 5.

Each of the plurality of wheels 3, 4, together with the corresponding wheel bracket 2125, can combine to form a commonly seen wheel-unit structure; and each of the plurality of wheels 3, 4 can rotate relative to the corresponding wheel bracket 2125, and during rotation, can be driven by the corresponding wheel drive means 5 to rotate around the first mounting shaft 501.
