Detailed Embodiment

[0033] The present utility model will be further described below in conjunction with the drawings and embodiments, but these specific implementation schemes do not limit the protection scope of the present utility model in any way.

[0034] Embodiment 1

[0035] See the attached Figures 1-4 , a chassis of a six-wheel and six-wheel-drive robot, the chassis system includes a vehicle body frame 1, a hub system 2, a battery compartment 3, an electric control compartment 4, an expansion compartment 5, an expansion bracket 6, and an inspection door 7.

[0036] The vehicle body frame 1 is the basic support structure of the entire system, welded by high-strength square tubes, dividing the chassis into two layers, the bottom layer and the upper layer. The hub system 2 and the battery compartment 3 are installed on the bottom layer structure, and the electric control compartment 4, the expansion compartment 5, the expansion bracket 6, and the inspection door 7 are arranged on the upper layer structure.

[0037] Among them, there are a total of six hub systems 2, namely the front left hub, the front right hub 14, the middle left hub, the middle right hub 15, the rear left hub, and the rear right hub 16. Each hub system 2 includes a detachable tire 21 and a hub motor 22. The hub motor 22 uses a brushless DC motor and is directly integrated inside the hub, reducing transmission losses. In addition, the tire 21 adopts an off-road tire design with a widened tread and deep tread patterns. The tread patterns are thick and the grooves are deep, improving the grip and anti-slip performance on complex roads such as mud and gravel. The hub motors 22 of the above-mentioned front left hub, front right hub 14, rear left hub, and rear right hub 16 are steering motors for controlling the steering of the entire chassis system.

[0038] The battery compartment 3 for powering the chassis system is located in the middle of the bottom layer. The battery compartment 3 adopts a modular design and can accommodate at least one storage battery 31. The capacity of the battery compartment 3 can be expanded according to requirements.

[0039] The electronic control compartment 4 is located at both ends of the upper structure and is divided into a front electronic control compartment 41 and a rear electronic control compartment 42 for installing chassis electrical control components. A front maintenance door 71 is installed at the front electronic control compartment 41, and a rear maintenance door 72 is installed at the rear electronic control compartment 42. A sealing strip 8 is provided around the opening of the electronic control compartment 4. When the front maintenance door 71 and the rear maintenance door 72 are closed, the sealing strip 8 is compressed to make the electronic control compartment 4 form a good sealing, waterproof and dustproof effect.

[0040] In addition, a charging electrode plate 13 is installed at the front maintenance door 71, and its positive and negative poles are connected to the battery compartment 3.

[0041] The front maintenance door 71 and the rear maintenance door 72 are each connected to the vehicle body through two hinges 9, and gas struts 10 are provided on both sides of each maintenance door 7, which can form a stable support for the door when the maintenance door 7 is opened, and anti-collision strips 12 are also installed in the outward extension directions of the front maintenance door 71 and the rear maintenance door 72.

[0042] An expansion compartment 5 is also provided in the middle of the upper layer of the chassis, between the front electronic control compartment 41 and the rear electronic control compartment 42. A middle cover plate 11 is detachably installed on the expansion compartment 5, and the middle cover plate 11 covers the expansion compartment 5, making the top of the chassis present as a large integral flat surface.

[0043] An expansion bracket 6 is also provided above the expansion compartment 5. The expansion bracket 6 adopts a "sub" - shaped structure and is fixed to the square tube frame by bolts. When there are fewer upper - mounted expansion functional devices, it can be directly fixed inside the expansion compartment 5, making the whole machine structure compact and beautiful in appearance. When there are more upper - mounted expansion functional devices, the devices can be installed on the expansion bracket 6 at the top. The large flat surface at the top and the expansion bracket 6 provide a great expansion and modification space. The expansion bracket 6 is directly and firmly connected to the frame, making the installation points of the upper - mounted chassis have high strength and the overall load - bearing capacity of the chassis is strong.

[0044] In practical applications, the operator can start the system through a remote control device or a vehicle-mounted control panel. After the system starts, a self-check program is first carried out to confirm that each subsystem is working properly. When driving, different driving modes can be selected according to the terrain, such as six-wheel synchronous drive, differential drive, etc. When encountering complex terrain, the intelligent off-road mode can be activated, and the system will automatically adjust the output power and steering angle of each wheel hub to obtain the best passing performance.

[0045] When expanding functions, the operator can install the corresponding function modules into the expansion compartment 5 according to the task requirements. The system will automatically identify the newly added modules and display the corresponding operation options on the control interface. During maintenance, internal inspection and part replacement can be conveniently carried out through the front and rear maintenance doors 7. Moreover, since the tire 21 and the in-wheel motor 22 are designed to be split and installed, the replacement of the tire 21 can be quickly completed, greatly improving the maintenance efficiency.

[0046] Through the above design, this multi-functional modular wheeled robot chassis system not only has excellent off-road performance and environmental adaptability, but also greatly improves the usage flexibility and maintenance efficiency, providing a reliable platform support for applications in various complex environments.

[0047] The above description is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention. Any innovative improvement or replacement based on the present invention should fall within the scope of the claims of the present invention. At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those of ordinary skill in the art can make various alternative selections, and these alternative solutions should also be regarded as falling within the protection scope of the present invention.
