[0034] Please see Figures 1-4 This application provides a new technical solution: a racing car chassis device, including a chassis frame, a wheel system structure, a power transmission mechanism, a speed monitoring mechanism and a wheel set switching mechanism. The chassis frame includes a main support 7, a secondary support 8 and a base plate 9. The main support 7 and the secondary support 8 are fixedly installed on both sides of the base plate 9 by bolts. The wheel system structure is symmetrically arranged on both sides of the main support 7 and the secondary support 8.

[0035] The wheel system structure includes a hub 1, a hub gear 2, axle 4, and bearing seat 5. The hub 1 and hub gear 2 are coaxially mounted via axle 4. Axle 4 is mounted on bearing seat 5, and bearing seat 5 is mounted on chassis frame.

[0036] Two sets of wheel systems are respectively provided on both sides of the main support 7 and the auxiliary support 8. The two sets of wheel systems are driven by a power transmission mechanism to drive the racing car chassis to move.

[0037] In use, the low center of gravity frame consisting of the main support 7, the secondary support 8, and the base plate 9 supports the symmetrical wheel system structure on both sides; the hub gear 2 in the wheel system meshes with the power transmission mechanism, and the motor 11 drives the hub 1 to rotate, thereby moving the chassis; the speed monitoring mechanism collects wheel speed data in real time and feeds it back to the motor to adjust the output; the wheel set switching mechanism allows the removal of part of the wheel system and the installation of the pulley block 6 to realize the conversion between a four-wheel and three-wheel structure.

[0038] The symmetrical wheel layout and low center of gravity frame significantly improve driving stability; the modular design supports rapid structural switching to adapt to different track requirements; real-time speed monitoring and feedback form a closed-loop control, improving handling precision.

[0039] In some embodiments, the base plate 9 is supported by carbon fiber composite material with a thickness of 3-5mm, and the surface of the base plate 9 is provided with several mounting holes or mounting grooves for mounting and fixing brackets and components. Its high specific strength and high stiffness characteristics can withstand the impact load of the high-speed movement of the racing car.

[0040] In some embodiments, the center height of the chassis frame does not exceed 30mm; the low center of gravity design reduces the roll angle during high-speed cornering, improves grip, and the flattened structure reduces wind resistance, which helps to improve top speed performance.

[0041] In some embodiments, the power transmission mechanism includes a motor 11 and a motor gear 12. The motor 11 is mounted on a base plate 9, and the motor gear 12 is mounted on the output shaft of the motor 11. The motor gear 12 meshes with hub gears 2 on two sets of gear train structures to drive the gear train structures to rotate. Simultaneous dual-wheel drive avoids slippage on one side and enhances straight-line driving stability.

[0042] In some embodiments, the speed monitoring mechanism is fixedly installed on the base plate 9 by bolts. The speed monitoring mechanism includes an encoder 13 and an encoder gear 14. One side of the encoder gear 14 meshes with the hub gear 2 to collect the speed information of the hub 1 in real time.

[0043] In this embodiment, the encoder 13 is electrically connected to the motor 11 and is used to control the motor 11 based on the rotational speed information of the wheel hub 1. The output torque of the motor 11 is dynamically adjusted according to the wheel speed difference to achieve active differential control, automatic power distribution to reduce tire wear, and extend component life.

[0044] In some embodiments, a forward-looking bracket 10 is fixedly mounted on the base plate 9 by bolts. The forward-looking bracket 10 may be equipped with a laser sensor or a camera for steering control of the racing car chassis.

[0045] In some embodiments, a wheel pad 3 is fitted onto the wheel hub 1, and the wheel pad 3 is made of rubber. It is fitted onto the outside of the wheel hub 1 through an interference fit or a snap-fit ​​structure, and generates friction when in contact with the ground. The replaceable wheel pad design allows for quick tire tread changes according to track conditions (such as dry / wet). The shock absorption characteristics of the wheel pad absorb road vibrations and improve driving comfort.

[0046] In some embodiments, the wheel switching mechanism includes a pulley block 6, which includes a pulley bracket and pulleys. By removing two wheel trains from the symmetrical wheel trains on both sides of the chassis frame and installing the pulley block 6 at the bottom of the base plate 9, it is used for switching between a four-wheel structure and a three-wheel structure. This meets the needs of various scenarios such as drift racing and short track speed racing.

[0047] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
