Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a vehicle body structure, in particular to a racing motorcycle model. Background Art

[0002] In the motorcycle category of the Smart Car competition, vehicle design must not only meet the speed and control requirements of the competition, but also be able to handle complex tracks and diverse driving scenarios. Traditional motorcycle models often use chain drive systems and high center of gravity layouts. While these designs can achieve good speed, they lack stability, handling, and energy efficiency.

[0003] The current motorcycle intelligent model faces several major problems as follows:

[0004] 1. Too high center of gravity: In traditional designs, key components such as batteries and motors are usually placed in the upper middle part of the frame, resulting in a higher center of gravity for the vehicle, which makes it easy to roll over or lose control when making sharp turns or driving at high speeds.

[0005] 2. Low energy efficiency of the transmission system: Traditional chain drive or belt drive systems have large friction losses, which affects the power transmission efficiency and are prone to problems such as chain loosening and vibration at high speeds.

[0006] 3. Intelligent control: Although existing motorcycle models have introduced certain sensors and control algorithms (such as PID), the integration of physical structure optimization and intelligent control systems is not high, and the potential of intelligent systems cannot be fully realized, especially the performance of vehicles on complex tracks is limited.

[0007] For example, Chinese Patent Document 201320878862.5 discloses a novel toy motorcycle characterized by comprising a body, front wheels, rear wheels, and a humanoid figure mounted on the body. A power drive is provided on one side of the rear wheel, and a steering drive is provided within the humanoid figure, connecting the humanoid figure to the rear end of the body. The advantageous effect of this utility model is that it eliminates the need to control the front wheel steering shaft to achieve steering. Instead, the steering drive drives the center of gravity offset component to the left and right, shifting the vehicle's center of gravity and tilting the vehicle to achieve steering. By installing a counterweighted iron ring on the wheel hub, the wheel's mass is significantly increased, boosting its moment of inertia during rotation. This ensures excellent balance during driving, even at low speeds. Auxiliary wheels are installed on each side of the vehicle body for support.

[0008] The above-mentioned technical solution adjusts the center of gravity by adjusting the center of gravity offset component to achieve steering function; at the same time, it uses the method of adding a counterweight iron ring to increase the stability of the center of gravity. However, this does not improve the layout of the vehicle itself. Increasing the counterweight also increases the weight of the entire vehicle, which is not conducive to competitive events where speed is the key, and it does not fundamentally solve the problem of instability caused by an excessively high center of gravity.

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 7 As shown, the racing motorcycle model includes a frame 1, to which a front wheel 18 and a rear wheel 16 are connected. The frame 1 extends between the front wheel 18 and the rear wheel 16 to form a load-bearing frame 1a. A load-bearing space is formed in the load-bearing frame 1a, and a vehicle floor 2 is installed in the load-bearing space. An electronic control mechanism is installed above the vehicle floor 2, and a battery mechanism is provided below the vehicle floor 2.

[0033] like Figure 2 As shown, the frame 1 preferably comprises two symmetrically arranged panels. The front sides of the panels are hingedly connected to the front wheel 18, and the rear sides of the panels are hingedly connected to the rear wheel 16. The central portion of the panels is convex downward, forming a side wall of the load-bearing frame 1a. The space between the two side walls forms a load-bearing space. The two panels are securely connected by a number of connecting frames. The overall frame 1 forms the main body of the motorcycle, connecting and supporting other components. The downward extension of the panels creates a load-bearing space, shifting most of the weight downward, keeping the center of gravity close to the ground and improving driving stability.

[0034] like Figure 2 、 3As shown in Figure 5, preferably, the vehicle floor 2 includes a flat plate body 2a, and flanges 2b are provided on opposite sides of the flat plate body 2a. The flanges 2b are fixed to the inner wall of the vehicle body by screws, and the flat plate body 2a is located between the two vehicle bodies.

[0035] The flat plate body 2a and the two side flanges 2b form a semi-frame structure. The floor panel 2 is constructed from lightweight, high-strength materials, ensuring the vehicle's rigidity while minimizing unnecessary weight. The floor panel 2's design also incorporates aerodynamic considerations to minimize wind resistance and maximize speed. Mounting holes are provided in the flanges 2b for attachment to the flat plate body 2a, allowing the flat plate body 2a to serve as a support for both upper and lower mounting.

[0036] like Figure 2 and 4 As shown, preferably, the electric control mechanism includes a support plate 3, a plurality of mounting holes 1 are provided on the support plate 3, screws 1 are passed through the mounting holes 1 and fixed to the top surface of the flat plate body 2a, and a circuit board 4 is provided on the support plate 3.

[0037] like Figures 2 to 3 As shown, preferably, a support frame 5 is further provided on the top surface of the flat plate body 2a, and the support frame 5 extends to both sides to form suspended plates, which extend beyond the flat plate body 2a, and a circuit board 6 is provided on the support frame 5.

[0038] The first circuit board 4 and the second circuit board 6 are specifically made of PCB boards. The circuit boards are installed through the support plate 3, and the support plate 3 and the circuit boards are independently installed on the upper surface of the vehicle bottom plate 2, forming independent maintenance and replacement, which greatly improves the maintainability of the vehicle and the convenience of long-term use.

[0039] like Figure 1 and 2 As shown, preferably, a window is opened on the lower convex wall of the vehicle body, and the suspended plate extends from the window. The window provides sufficient installation space for the circuit board 2 6, and the suspended plates on both sides of the support plate 3 extend symmetrically to improve balance.

[0040] like Figure 1 、 2 As shown in Figure 6, preferably, the battery mechanism includes a battery compartment 7 and batteries. The battery compartment 7 is a box body 7a with an inlet and outlet on one side. The top of the battery compartment 7 is expanded to form a mounting plate 7b. The mounting plate 7b has a plurality of mounting holes 2 formed therein. The mounting holes 2 are threaded with screws 2 to secure the battery to the bottom surface of the flat body 2a. The batteries are placed into the battery compartment 7 through the inlet and outlet. The front side of the battery compartment 7 is provided with an inlet and outlet, and the two side walls and rear wall of the battery compartment 7 are provided with hollow openings. The hollow openings allow the internal batteries to be observed while reducing the overall weight of the battery compartment 7.

[0041] like Figure 7As shown, preferably, it is located behind the load-bearing frame 1a, and the two car plate bodies are connected to the two rear car plates 8 in a one-to-one correspondence. The rear wheels 16 are hinged between the two rear car plates 8 through a hinge shaft, and the driven gear 13 is sleeved on the hinge shaft. The drive motor 9 is installed on the rear car plate 8, and the driving gear 10 is fixed on the driving shaft of the drive motor 9. The transmission gear 11 and the transmission gear 2 12 are hinged on the rear car plate 8, and the driving gear 10 is engaged with the transmission gear 11 through teeth, and the transmission gear 11 is engaged with the transmission gear 2 12 through teeth, and the transmission gear 2 12 is engaged with the driven gear 13 through teeth, and the driven gear 13 is engaged with the encoding gear 14 through teeth, and the encoding gear 14 is connected to the encoder 15 through the middle shaft.

[0042] The driving motor 9 drives the driving gear 10 to rotate in a directional manner, and through engagement, it drives the transmission gear 11, transmission gear 2 12, driven gear 13 and encoding gear 14 to rotate in sequence. The driven gear 13 drives the rear wheel 16 to rotate through the articulated shaft to provide forward power, and the encoding gear 14 inputs the rotation speed into the encoder 15 for speed measurement.

[0043] Compared to traditional chain or belt drives, this motorcycle model uses a gear drive, which reduces friction loss, improves transmission efficiency, and ensures stable and continuous power transmission.

The front ends of the two vehicle panels are connected by the front fork frame 17, and the front fork frame 17 connects the vehicle frame 1 and the front wheel 18. Under the drive of the rear wheel 16, the front wheel 18 is driven synchronously.

[0046] The specific optimization aspects of the design of this racing motorcycle model are as follows:

[0047] 1. By extending the vehicle floor between the front wheel 18 and the rear wheel 16 and adding a floor plate 2, a load-bearing space is created in the lower middle area close to the ground. The electronic control mechanism and battery mechanism are moved from a higher position to a lower middle position. This lowers the center of gravity of the vehicle without increasing the weight of the entire vehicle. The low center of gravity design not only improves stability during cornering, but also helps to better distribute weight during driving, reducing body tilt, thereby increasing safety and improving racing time.

[0048] 2. Gear drive replaces traditional chain or belt drives, effectively preventing problems such as chain shedding and wear that can reduce transmission ratios. Gear drive reduces friction loss, improves transmission efficiency, and ensures stable and continuous power delivery. Furthermore, gear drive systems offer lower maintenance costs, making them more suitable for extended use during competitions.

[0049] 3. The modular design of each component allows for independent maintenance and replacement of components such as the vehicle floor 2, battery, support plate 3, and circuit board, significantly improving the vehicle's maintainability and ease of long-term use. This modular design ensures compact and independent connections between components, facilitating assembly and maintenance. This not only reduces vehicle maintenance but also facilitates quick component replacement during competition, improving overall operational efficiency.
