[0028] As Figure 1 shown Figure 4 shown, in an embodiment of the present utility model, an intelligent vehicle teaching platform convenient for modular construction includes a vehicle frame 1, a wheel 2 is rotatably connected to the vehicle frame 1, protective members 101 are respectively arranged at the front and rear of the vehicle frame 1, both ends of the protective members 101 extend beyond the center plane of the wheel 2 to both sides of the vehicle frame 1, and module mounting holes 102 are arranged on the protective members 101.

[0029] In this embodiment, protective members 101 are provided at the front and rear of the vehicle frame 1, respectively. The protective members 101 are used to protect the wheels 2 and the electronic components inside the frame 1 when the vehicle is running. The ends of the protective members 101 extend beyond the center plane of the wheels 2, thereby increasing the protection range and further improving the protection performance of the vehicle, thereby providing more comprehensive protection for each module on the frame 1.

[0030] At the same time, the module mounting hole 102 on the protective part 101 provides convenience for subsequent modular construction. Learners can install various functional modules (such as sensors, controllers, actuators, etc.) on the protective part 101 according to teaching needs or their own creativity, so as to realize personalized customization and function expansion of the smart car. For example, the pressure sensor on the protective part 101 can be used for collision testing. The learning threshold is low, allowing beginners to get started quickly and stimulate learners' innovative thinking and hands-on ability.

[0031] This teaching platform not only plays an important role in education, but also provides strong support for scientific research institutions, corporate R&D departments, etc. Through this platform, researchers can quickly build smart car prototypes that meet specific needs and conduct performance testing and algorithm verification.

[0032] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the wheel 2 includes two power wheels 201 arranged opposite to each other, and the power wheels 201 are respectively connected to a drive motor 202.

[0033] The wheel 2 includes two steering wheels 203 arranged opposite to each other. The steering wheels 203 are connected to the steering motor 205 through an Ackerman steering mechanism 204.

[0034] Steering avoidance grooves 103 are provided at the steering wheels 203 on both sides of the vehicle frame 1 .

[0035] The powered wheels 201 drive the vehicle. Each powered wheel 201 is directly connected to a drive motor 202. When the power is turned on and the control system issues a command, the drive motor 202 begins operating, outputting torque to drive the powered wheels 201 to rotate, thereby propelling the entire vehicle forward or backward. The steering wheels 203 are used to control the vehicle's direction of travel. The two steering wheels 203 are connected to the steering motor 205 via an Ackerman steering mechanism 204. The Ackerman steering mechanism 204 is a mechanical device used to rotate the wheels 2 along a predetermined trajectory, ensuring that the inner and outer wheels 2 can rotate at different angles when the vehicle turns, thereby achieving smooth steering. When the control system issues a steering command, the steering motor 205 begins operating, transmitting power to the steering wheels 203 through the Ackerman steering mechanism 204, causing them to rotate at a predetermined angle and direction, thereby changing the vehicle's direction of travel.

[0036] In this embodiment, the two driving wheels 201 enable the intelligent vehicle teaching platform to obtain stronger driving force during driving and can cope with various road conditions. The Ackermann steering mechanism 204 enables the steering wheels 203 to move along an ideal trajectory during turning, reducing the wear of the tires 207 and the steering resistance, and improving the stability and controllability of the vehicle. Through the precise control of the steering motor 205, the intelligent vehicle can achieve fast and accurate steering actions and can meet the driving requirements in complex scenarios. In addition, the steering avoidance groove 103 enables the steering wheels 203 to have sufficient space for rotation during the steering process, thus avoiding steering interference caused by the structural limitation of the vehicle frame 1 and ensuring the handling flexibility and driving stability of the intelligent vehicle teaching platform.

[0037] In practical applications, the wheels can also be driven wheels arranged in the middle and a pair of driven wheels arranged at the edge. The driven wheels are universal wheels, and the driving wheels are respectively connected with driving motors. By controlling the rotation speed and steering of the driving motors, the driving speed and direction of the intelligent vehicle teaching platform can be controlled. When the two driving wheels rotate at the same speed, the platform will move straight; while when the two driving wheels rotate differentially, steering operations can be achieved, and in-situ steering can also be realized, enabling it to adapt to narrow spaces. On the one hand, the driven wheels assist in supporting the intelligent vehicle teaching platform, enabling the platform to move stably; on the other hand, the driven wheels are universal wheels and can rotate freely, facilitating steering.

[0038] As Figure 2 shown, in a preferred example, the wheel 2 includes a wheel hub 206 and a tire 207 sleeved on the wheel hub 206. The outer surface of the tire 207 does not exceed the end face of the wheel hub 206, and the end face of the wheel hub 206 is an arc surface.

[0039] The tire 207 is a solid rubber tire or a pneumatic rubber tire, and anti-slip textures are provided on the surface.

[0040] By making the outer surface of the tire 207 not exceed the end face of the wheel hub 206 and the end face of the wheel hub 206 be an arc surface, the tire 207 can be protected and the overall aesthetics of the wheel 2 can be improved. At the same time, whether it is a solid rubber tire or a pneumatic rubber tire, anti-slip textures are provided on the surface, enhancing the grip of the wheel 2 and ensuring the driving stability and safety under different road conditions. Especially in complex road conditions such as wet and slippery roads, the anti-slip textures can effectively prevent the wheel 2 from slipping.

[0041] As Figure 1 and Figure 2 shown, in a preferred example, the vehicle frame 1 includes a bottom plate 104 and a top plate 105. A plurality of partition plates 106 are arranged between the bottom plate 104 and the top plate 105. The partition plates 106 divide the interior of the vehicle frame 1 into multiple accommodation spaces. The lower accommodation space is used to place the battery 3, the speaker 4, the driving motor 202, and the steering motor 205, and the upper accommodation space is used to place the main board 5.

[0042] In this embodiment, by arranging a partition 106 between the bottom plate 104 and the top plate 105, the interior of the vehicle frame 1 is divided into multiple accommodation spaces, which can effectively utilize the limited space resources and achieve an orderly layout of each component. The lower accommodation space is used to place components with relatively large weights such as the battery 3, the speaker 4, the drive motor 202, and the steering motor 205, which helps to stabilize the center of gravity of the vehicle and improve the driving safety. The upper accommodation space is used to place precision control components such as the main board 5, away from the lower components that may generate vibrations and interference, ensuring the stable operation of the electronic system.

[0043] As Figure 1 shown, in a preferred example, a radar 6 is provided on the top of the top plate 105, and inclined surfaces 107 are respectively provided at both ends of the top plate 105.

[0044] A display screen 7 is provided on one inclined surface 107, and a camera 8 is provided on the other inclined surface 107. The heights of the display screen 7 and the camera 8 are not higher than the vertex of the inclined surface 107. The display screen 7 is a touch screen and is detachably installed on the top plate 105.

[0045] In this embodiment, the surrounding environment is scanned in real time by the radar 6. The radar 6 can capture target information such as obstacles, pedestrians, and vehicles. The inclined surface 107 enables the radar 6 to have a wider field of view, provides key data support for advanced functions such as autonomous navigation and obstacle avoidance of the intelligent vehicle, enhances the safety of the intelligent vehicle, and provides a strong guarantee for its autonomous driving in a complex environment.

[0046] The setting of the display screen 7 provides an intuitive information display window for the intelligent vehicle. Through the display screen 7, important data such as the vehicle status, driving parameters, and navigation information can be displayed in real time, providing instant feedback and guidance for learners. At the same time, the display screen 7 can also be used to control the vehicle driving and the operation of each module.

[0047] The camera 8 is used to capture the real-time image in front of the vehicle, providing visual input for functions such as autonomous navigation, obstacle recognition, and pedestrian detection of the intelligent vehicle. By setting the camera 8 on the inclined surface 107, it can ensure that the camera 8 has a wider field of view, reduce the blind area caused by occlusion, and improve the accuracy and reliability of environmental perception. In addition, controlling the heights of the display screen 7 and the camera 8 below the vertex of the inclined surface 107 helps to protect the devices and prevent the tall components from being easily damaged when passing through the low aisles.

[0048] As Figure 3 shown, in a preferred example, a support plate 108 is provided between the partition 106 and the bottom plate 104 or the top plate 105, and a connection hole 109 is provided on the support plate 108.

[0049] An access opening 110 is provided on the bottom plate 104, and a cover plate 111 is provided at the access opening 110.

[0050] In this embodiment, the support plate 108 enhances the stability of the vehicle frame 1 and also provides a firm mounting point for various functional modules (such as sensors, controllers, actuators, etc.) through the connection holes 109 thereon, making the installation and disassembly of the functional modules simpler and faster, which is beneficial for learners to conduct modular experiments and explorations, and improves the flexibility and scalability of the teaching platform.

[0051] Meanwhile, the design of the access opening 110 provided on the bottom plate 104 and the equipped cover plate 111 facilitates the maintenance and module expansion of the vehicle. The provision of the access opening 110 enables convenient access to key components such as the battery 3, motor, control board, etc. inside the vehicle when needed, facilitating daily inspections, maintenance, and troubleshooting. The cover plate 111 is used to protect the devices inside the vehicle frame 1 and ensure the safety of the access opening 110 when not in use.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
