Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle frame structure design and reinforcement technology, and in particular to a main beam tube reinforcement device for electric motorcycles. Background Technology

[0002] In modern transportation systems, electric motorcycles are increasingly becoming a popular choice for urban commuting and short-distance travel due to their advantages such as environmental protection, economy, and flexibility. With the popularization of electric motorcycles and the expansion of application scenarios, users have put forward higher requirements for their performance and safety. As the core load-bearing component of the electric motorcycle frame, the main beam tube's structural strength is directly related to the safety and reliability of the entire vehicle.

[0003] However, existing main beam reinforcement devices for electric motorcycles have the following drawbacks:

[0004] (1) If the traditional connection structure is not firmly fixed, the gap between the installation components and the connecting rod may increase or the connection may fail during long-term vibration, which may lead to component displacement, abnormal noise or even a decrease in structural stability.

[0005] (2) Traditional fixed structure has fixed dimensions, which makes it difficult to match the installation position changes of the main beam tube of different models, resulting in poor versatility.

[0006] Therefore, this utility model provides a main beam tube reinforcement device for electric motorcycles. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a main beam tube reinforcement device for an electric motorcycle, including a frame 1, two connecting rods 2 are fixedly connected to the inner side wall of the frame 1, an installation component 3 is provided on the surface of the connecting rod 2, a threaded sleeve 4 is provided on the surface of the installation component 3, and an extension component 5 is provided inside the threaded sleeve 4.

[0029] The mounting assembly 3 includes an upper clamping plate 301 and a lower clamping plate 302 respectively disposed on the surface of the connecting rod 2. A threaded sleeve 4 is rotatably connected to one side of the upper clamping plate 301, and a threaded sleeve 4 is fixedly connected to one side of the lower clamping plate 302. Connecting blocks 303 are fixedly connected to the other side of the upper clamping plate 301 and the lower clamping plate 302, serving as the connection fulcrum for the upper clamping plate 301 and the lower clamping plate 302. The two are locked together by bolts 304 that penetrate through the surface, converting the clamping force of the clamping plate on the main beam tube into the preload force of the bolts 304, ensuring the durability of the clamping state. The surfaces of the two connecting blocks 303 are threaded with bolts 304, and the upper clamping plate 301 and the lower clamping plate 302 are firmly locked through the threaded fastening action. The continuous clamping force generated by the thread engagement can resist the vibration and bumps during vehicle operation, prevent the clamping plates from loosening, and ensure stable clamping of the main beam tube.

[0030] The extension component 5 includes a bidirectional threaded rod 501 threaded inside the threaded sleeve 4. Through precise thread transmission with the threaded sleeve 4, the extension length can be adjusted to adapt to main beam tubes of different diameters or positions. At the same time, it can dynamically compensate for gaps after long-term wear and maintain clamping force. A fixing ring 502 is fixedly connected to the surface of the bidirectional threaded rod 501, and a rotating rod 503 is fixedly connected to the surface of the fixing ring 502. The rotating rod 503 is connected to the bidirectional threaded rod 501 through the fixing ring 502 to form a lever structure, which allows the operator to rotate the threaded rod with little effort, realizing convenient operation of length adjustment and solving the problem of traditional fixed structure adjustment requiring tools and effort.

[0031] A storage box 6 is fixedly connected to the inner wall of the frame 1. The storage box 6 is rectangular and provides convenient storage space. It can be used to store cycling tools, personal items or small accessories, improving the practicality and space utilization of the device.

[0032] The inner side wall of frame 1 is fixedly connected to a controller mounting plate 7. The surface of the controller mounting plate 7 is provided with mounting holes, which are specifically used to fix the controller of the electric motorcycle. The controller is securely installed by means of the mounting holes and bolts 304, ensuring that its relative position with the frame remains unchanged.

[0033] A mounting block 8 is fixedly connected to one side of the frame 1. The surface of the mounting block 8 is provided with mounting holes, which serve as the connection interface between the device and other components, and allow for flexible expansion and installation through the mounting holes.

[0034] The bottom of the frame 1 is fixedly connected to the battery compartment 9, which is made of stainless steel and is used to place and fix the lithium battery. Stainless steel has the characteristics of corrosion resistance and high strength, which can protect the battery from external impact, rainwater erosion and road gravel impact.

[0035] One end of the frame 1 is fixedly connected to a mounting tube 10. The mounting tube 10 is circular and serves as a tubular connector. It can be used to install handlebar stems, fork assemblies, or other tubular structural components. The circular design matches the tubular structure of the corresponding accessories, ensuring the sealing and stability of the connection.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: The upper clamping plate 301 and the lower clamping plate 302 achieve initial positioning by wrapping the surface of the connecting rod 2. Bolts 304 are used to pass through the two connecting blocks 303 and tighten them, so that the upper clamping plate 301 and the lower clamping plate 302 are tightly attached to the connecting rod 2, thereby fixing the entire installation assembly 3 to the connecting rod 2 of the frame 1. The upper clamping plate 301 is rotatably connected to the threaded sleeve 4, and the lower clamping plate 302 is fixedly connected to the threaded sleeve 4. This design allows the threaded sleeve 4 to make slight adjustments to the angle relative to the upper clamping plate 301, ensuring that the extension assembly 5 can adjust its direction according to the actual position of the main beam tube, thus improving the installation adaptability.

[0038] The second step: The bidirectional threaded rod 501 is threadedly connected to the threaded sleeve 4. By rotating the rod 503, the bidirectional threaded rod 501 can be extended and retracted along the axial direction of the threaded sleeve 4, thereby changing the overall length of the extension assembly 5. When the bidirectional threaded rod 501 extends to contact the main beam tube of the electric motorcycle, it is further finely adjusted to a moderate tightness, which can form a rigid support for the main beam tube and share the load borne by the frame 1.

[0039] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.

However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.
