Description

Technical Field

[0001] This application relates to the field of toy car technology, and in particular to a drift car. Background Technology

[0002] The current children's electric vehicle market generally adopts a traditional four-wheel or three-wheel structure. Their steering systems are mostly based on Ackermann geometry or simple differential designs, achieving steering through mechanical linkage between the steering wheel and the front wheels. These vehicles are typically equipped with a single drive motor and a reduction gear set to drive either the rear or front wheels. During steering, they can only change the wheel angle through physical limits, and cannot achieve active torque distribution control. While this design can meet basic driving needs, it has significant limitations in dynamic handling: the turning radius is greatly constrained by the mechanical structure, and it lacks the ability to actively create a sideslip posture, making it difficult to achieve entertaining drifting maneuvers.

[0003] While professional-grade drift remote control cars that have emerged in recent years can independently control the differential speed of dual motors through electronic speed controllers to achieve precise torque distribution and drifting effects, their technical architecture has significant flaws: relying on complex electronic sensing systems, microcontrollers, and high-cost ESC modules not only greatly increases manufacturing costs but also poses safety hazards due to the system's complexity exceeding children's operational capabilities. Furthermore, the response delay of the electronic control system can lead to unpredictable vehicle dynamics, easily causing sudden rollover risks when children make rapid turns.

[0004] Existing children's vehicles still face technological gaps in enhancing their fun factor: on the one hand, traditional mechanical steering vehicles cannot achieve controllable drifting; on the other hand, electronic differential solutions are difficult to popularize among children due to cost and safety concerns. Therefore, there is an urgent need to develop a reliable solution based on mechanical transmission that can give children's vehicles controllable drifting capabilities while ensuring safety and meeting the requirements for low-cost mass production. Utility Model Content

[0005] This application provides a drift car to at least solve the technical problem of excessively high mass production costs of drift cars in related technologies.

[0006] To achieve the above objectives, this application provides a drift car, including a car body, a drive wheel mounted on the front side of the car body, and a driven wheel mounted on the rear side of the car body. The drive wheel includes a first drive wheel and a second drive wheel respectively disposed on both sides of the car body. A drive motor for driving the rotation of the first drive wheel and the second drive wheel is respectively disposed in the first drive wheel and the second drive wheel. The drive motor is electrically connected to a power source inside the car body. A steering wheel for controlling the steering of the car body is disposed on the car body. A commutator for controlling forward and reverse rotation is electrically connected to the first drive wheel and the second drive wheel respectively. The steering wheel is kinetically connected to the commutator.

[0007] In some embodiments, the steering wheel is provided with a rotatable lever, and the left and right sides of the lever are respectively provided with a first commutator for controlling the forward and reverse rotation of the first drive wheel and a second commutator for controlling the forward and reverse rotation of the second drive wheel. Rotating the lever will abut against the first commutator or the second commutator.

[0008] In some embodiments, the first commutator is disposed on the side closer to the first drive wheel, and the second commutator is disposed on the side closer to the second drive wheel.

[0009] In some embodiments, the first commutator and the second commutator are respectively provided with a reversing switch on the side near the toggle member, and rotating the toggle member will press the reversing switch.

[0010] In some embodiments, the commutator is provided with a spring piece outside the commutator switch for abutting and engaging with the toggle member. The spring piece is pressed against the commutator switch by the pressure of the toggle member, and the spring piece resets after the toggle member moves away from the spring piece.

[0011] In some embodiments, the vehicle body is provided with a transmission frame that can move left and right, the first drive wheel and the second drive wheel are respectively mounted at both ends of the transmission frame, and a transmission rod extends from the lower end of the steering wheel, the transmission rod being connected to the transmission frame in a transmission manner.

[0012] In some embodiments, the transmission rod includes a rod body, a bent portion perpendicular to the rod body, and an extension portion parallel to the rod body extending from the other end of the bent portion. Rotating the rod body causes the extension portion to have an arc-shaped travel trajectory. The rod body is connected to the steering wheel, and the extension portion is drively connected to the transmission frame.

[0013] In some embodiments, the transmission frame is provided with a mounting hole that mates with the extension, and the extension is movably installed in the mounting hole and drives the transmission frame to move left and right through the mounting hole.

[0014] In some embodiments, the actuating element is mounted on the drive rod and rotates with the drive rod.

[0015] In some embodiments, the driven wheel is a caster wheel that can rotate in any direction.

[0016] Based on the above, the beneficial effects of the technical solution of this application compared with the prior art are as follows: This application uses a toggle device connected to the steering wheel transmission to make the steering wheel press the reversing switch when it is turned, thereby causing the drive motor in the drive wheel to reverse and achieve a drifting effect. This solution does not require a precision differential, which greatly reduces the production cost of drift cars. Attached Figure Description

[0027] This application provides a drift car, including a car body, drive wheels mounted on the front side of the car body, and driven wheels mounted on the rear side of the car body. The drive wheels include a first drive wheel and a second drive wheel respectively disposed on both sides of the car body. A drive motor for driving the rotation of the first drive wheel and the second drive wheel is respectively disposed in the first drive wheel and the second drive wheel. The drive motor is electrically connected to a power source inside the car body. A steering wheel for controlling the steering of the car body is disposed on the car body. A commutator for controlling forward and reverse rotation is electrically connected to the first drive wheel and the second drive wheel respectively. The steering wheel is drivenly connected to the commutator.

[0028] Implementation, for example Figures 1-5 As shown, a drift car includes a car body 1, a drive wheel mounted on the front of the car body 1, and a driven wheel 1.2 mounted on the rear of the car body 1. The driven wheel 1.2 is a swivel wheel that can rotate in any direction to facilitate drifting. The drive wheel has a built-in drive motor 2.3 electrically connected to the power supply inside the car body 1. Starting the drive motor 2.3 drives the drive wheel to rotate.

[0029] Furthermore, the vehicle body 1 is equipped with a steering wheel 1.1 for controlling the steering of the vehicle body 1. The drive wheels include a first drive wheel 2.1 and a second drive wheel 2.2 respectively located on both sides of the vehicle body 1. A transmission rod 3 extends from the lower end of the steering wheel 1.1 and rotates with it. A toggle member 4 is provided on the transmission rod 3 and rotates with it. A first commutator 5.1 and a second commutator 5.2 are respectively located on the left and right sides of the toggle member 4. The steering wheel 1.1 is connected to the first commutator 5.1 and the second commutator 5.2 through the toggle member 4. The first commutator 5.1 is located on the side closer to the first drive wheel 2.1, and the second commutator 5.2 is located on the side closer to the second drive wheel 2.2. The first commutator 5.1 is electrically connected to the drive motor 2.3 inside the first drive wheel 2.1, and the forward and reverse rotation of the first drive wheel 2.1 can be controlled by controlling the forward and reverse rotation of the drive motor 2.3; the second commutator 5.2 is electrically connected to the drive motor 2.3 inside the second drive wheel 2.2, and the forward and reverse rotation of the second drive wheel 2.2 can be controlled by controlling the forward and reverse rotation of the drive motor 2.3.

[0030] Specifically, the first commutator 5.1 and the second commutator 5.2 each have a reversing switch 5.3 on the side near the actuating element 4. A spring piece 5.4 for abutting against the actuating element 4 is located outside the reversing switch 5.3 on each commutator. Turning the steering wheel 1.1 causes the actuating element 4 to rotate, which in turn presses against the spring piece 5.4 on either the first commutator 5.1 or the second commutator 5.2. The spring piece 5.4, under the pressure of the actuating element 4, presses against the reversing switch 5.3, causing the drive motor 2.3 to reverse, which in turn drives the drive wheels to reverse. The left and right drive wheels rotate in opposite directions, thus achieving a drifting operation. When the steering wheel 1.1 returns to center, the actuating element moves away from the spring piece 5.4, and the spring piece 5.4 returns to its original position.

[0031] Furthermore, a movable transmission frame 6 is provided on the front side of the interior of the vehicle body 1, with the first drive wheel 2.1 and the second drive wheel 2.2 respectively mounted on the left and right ends of the transmission frame 6. The transmission rod 3 includes a rod body 3.1, a bent portion 3.2 perpendicular to the rod body 3.1, and an extension portion 3.3 extending from the other end of the bent portion 3.2 parallel to the rod body 3.1. The design of the bent portion 3.2 ensures that the extension portion 3.3 has an arc-shaped travel trajectory when the rod body 3.1 is rotated. The rod body 3.1 is connected to the steering wheel 1.1. The transmission frame 6 has a mounting hole 6.1 that mates with the extension portion 3.3, and the extension portion 3.3 is movably mounted within the mounting hole 6.1. The extension portion 3.3, through its arc-shaped travel trajectory and contact with the mounting hole 6.1, drives the transmission frame 6 to move left and right. This left and right movement of the transmission frame 6, in turn, pushes the drive wheels to deflect left and right, achieving steering.

[0032] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
