Description

Technical Field

[0001] This application relates to the field of unicycle technology, and in particular to a vehicle body connection structure and a unicycle. Background Technology

[0002] Existing unicycles generally employ a multi-level connection structure between the battery compartment and the frame. This involves setting multiple transitional connectors (such as mounting brackets, adapter plates, and buffer pads) on the outside of the battery compartment or inside the frame to achieve assembly and fixation. This structure not only increases the number of parts, assembly steps, and material costs, but also easily leads to loosening and abnormal noises during long-term use due to the excessive number of connection points. Especially on bumpy roads, the gaps between multiple connectors may gradually widen due to vibration, affecting the overall structural stability and safety performance. In addition, the complex connection layout also encroaches on the unicycle's internal space, limiting the design freedom of battery capacity or other functional modules. Therefore, there is an urgent need for a simpler and more reliable direct connection solution that can ensure structural strength while achieving more efficient assembly and maintenance, and improving the overall structural integration and durability of the vehicle. Utility Model Content

[0022] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 4 According to an embodiment of this application, the vehicle body connection structure includes a first housing 100 and a second housing 200. The first housing 100 has a first end 101 and a second end 102. The first end 101 forms a first interface 110, and the second end 102 is used to connect a wheel 300. The second housing 200 is detachably connected to the first housing 100. The second housing 200 has a first side 201 and a second side 202. The first side 201 is provided with a second interface that cooperates with the first interface 110, and the second side 202 forms the top surface of the vehicle body.

[0024] The vehicle body connection structure achieves direct docking between the two main structures by setting a first interface 110 at the first end 101 of the first housing 100 and a matching second interface on the first side 201 of the second housing 200. This design significantly reduces the number of transitional connectors (such as mounting brackets, adapter plates, and buffer pads) required in traditional solutions, making the overall structure more compact and optimizing the weight. It also significantly reduces assembly complexity and the number of parts. At the same time, the direct docking of the first housing 100 and the second housing 200 enhances the connection rigidity between the housings. While ensuring the overall structural strength of the unicycle, it provides a spatial basis for the reasonable layout and reliable installation of functional components such as batteries and control boards, which is conducive to improving the structural stability and durability of the unicycle.

[0025] Reference Figure 1 , Figure 2 and Figure 4In some embodiments, the vehicle body connection structure includes a handle 400. A first mounting portion 120 for mounting the handle 400 is provided on the first housing 100. The handle 400 is located at the first end 101 of the first housing 100. The first mounting portion 120 makes the installation of the handle 400 more stable. In other words, by setting the first mounting portion 120, not only is a clear positioning reference provided for the handle 400, but the local structural strength of the connection area with the first housing 100 is also enhanced. On this basis, screws and other connecting parts are used to fasten the handle 400 to the first housing 100, realizing redundant protection of the mechanical connection. This ensures that the handle remains stable and reliable under long-term carrying, shaking or impact, effectively avoiding safety hazards caused by loosening or falling off the connection, and improving the safety and durability of the product.

[0026] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the handle 400 includes a front handle 410 and a rear handle 420, which are arranged radially opposite each other on the front and rear sides of the first housing 100.

[0027] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the vehicle body connection structure includes a parking bracket 600 and a crash protection component 700. Both the parking bracket 600 and the crash protection component 700 are mounted on the first housing 100. The parking bracket 600 and the rear handle 420 are located on the same side of the first housing 100, which facilitates stable and convenient parking by the user through the rear handle 420. The crash protection component 700 and the front handle 410 are located on the same side of the first housing 100. When the front of the unicycle is hit by a collision or accidental impact, the structure of the front handle 410 can effectively absorb and disperse the impact force, giving priority to protecting the key structure of the vehicle body and internal electronic components, and improving the protection and durability of the whole vehicle in complex usage environments.

[0028] In some embodiments, the vehicle body connection structure includes a first pedal and a second pedal, which are arranged opposite to each other on both sides of the first housing 100 along the axial direction of the wheel 300, as shown in the figure. Figure 1 , Figure 2 and Figure 4The first housing 100 is provided with a connecting component 800 for mounting the first pedal and the second pedal. The connecting component 800 is used to mount and support the first pedal and the second pedal. Originally, the pedals could be directly mounted on the first housing 100. Compared with the traditional solution of directly fixing the first pedal and the second pedal to the first housing 100, this embodiment, by adding the connecting component 800, not only enhances the overall rigidity of the first housing 100, but also facilitates the flexible adjustment of the mounting height and posture of the first pedal and the second pedal, improving adjustability and structural stability. Furthermore, in a preferred embodiment, a reinforcing rib can be added to the first housing 100 as a snap-fit ​​part. This snap-fit ​​part can form a snap-fit ​​with the connecting component 800, thereby achieving quick installation, accurate positioning and reliable limiting, further improving the overall strength and assembly convenience of the connection structure. It can be understood that the connecting component 800 has multiple mounting positions along the radial direction of the wheel 300, which facilitates the height adjustment of the first pedal and the second pedal, making it convenient for users.

[0029] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the vehicle body connection structure includes a retractable rod 500. A second mounting portion for mounting the retractable rod 500 is provided on the first housing 100. The retractable rod 500 is located between the rear handle 420 and the first housing 100. This arrangement allows the retractable rod 500 to fit snugly against the vehicle body contour when stored, effectively saving space and maintaining a neat overall appearance. When towing is required, the retractable rod 500 can be quickly extended, providing users with a labor-saving and convenient mode of movement. Through the positioning and support of the second mounting portion, combined with the retractable structure of the retractable rod 500 itself, efficient conversion between storage and use states is achieved, improving the portability and user experience of the unicycle.

[0030] Reference Figure 4 In some embodiments, the vehicle body connection structure includes a shock absorber 900, one end of which is connected to the wheel 300 and the other end is installed in the first housing 100. The shock absorber 900 can significantly improve riding smoothness and comfort, while also helping to reduce the dynamic stress on the vehicle body structure and extend the service life of key components.

[0031] Reference Figure 4In some embodiments, the first housing 100 houses a battery 130 to form a battery compartment. The battery 130 is located on the outer periphery of the shock absorber 900, achieving compact space utilization and providing better overall protection for the battery during driving through the first housing structure. The second housing 200 houses a control motherboard to form a motherboard compartment. The control motherboard is electrically connected to the battery 130. This layout arranges key electrical components in separate zones, which is beneficial for heat dissipation and electromagnetic compatibility management. At the same time, it facilitates independent maintenance of each functional module during maintenance, improving the reliability, safety and maintainability of the unicycle.

[0032] In some embodiments, both the first housing 100 and the second housing 200 are made of metal. Using a metal housing not only improves the overall rigidity and impact resistance of the vehicle structure, but also enhances the physical protection of key components (such as the battery compartment and motherboard compartment). In addition, the first housing 100 can be provided with multiple limiting grooves and limiting holes to facilitate the rapid and accurate positioning and installation of various functional components (such as sensors, lighting modules, expansion interfaces, etc.). This design significantly improves the modular expansion capability of the vehicle structure, which is conducive to meeting users' personalized needs and subsequent functional upgrades, while also improving the consistency and efficiency of production and assembly.
