Description

Technical Field

[0001] This utility model relates to the field of vehicle frame connector technology, and in particular to a reinforced connector for electric vehicle frames. Background Technology

[0002] The electric vehicle frame is the main structure of the electric vehicle, which plays the role of supporting and connecting various components. The frame reinforcement connectors are special components designed to enhance the structural strength of the frame and improve the stability and safety of the vehicle. For example, bolts and nuts are the most common connectors. By passing the bolts through the connecting holes of the frame and then tightening them with nuts, different frame components can be tightly connected together. Its advantages are that the connection is firm, disassembly is convenient, and maintenance and replacement of parts are easy.

[0003] Existing reinforced connectors may be designed for specific vehicle models or frame structures. If users want to modify or replace parts of an electric vehicle, they may find that the existing reinforced connectors are incompatible with the new parts. For example, some reinforced side support connectors may only be suitable for specific frame and single support legs. When users want to replace the single support leg with a different style, they may not be able to install and use it directly.

[0004] Therefore, most of the existing reinforced connectors mentioned above are likely custom-made. If users want to modify or replace parts of an electric vehicle, they may find that the existing reinforced connectors are incompatible with the new parts, reducing their versatility. A reinforced connector for an electric vehicle frame could be designed to improve the connector's applicability by adjusting the connection part. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: By setting a rotatable rotating plate to cooperate with the support plate, the connector can be flexibly adjusted to a suitable angle according to the relative position of the two sets of frame components, solving the problem of inconsistent installation angles between different frame components; combined with the adjustable and fixed arc-shaped clamp on the rotating plate and the selectable and adaptable connecting sleeve structure, it can fix and install frame components of different sizes, effectively overcoming the defect of existing connectors that only adapt to a single model, thus achieving compatibility with different brands and models of electric vehicle frames, including simple electric vehicles and electric motorcycles, significantly expanding the application range of the connector. Due to the good compatibility of this connector, in During the replacement or upgrade of electric vehicle components, as long as the original connectors are not damaged, they can continue to be used. This avoids the need to repeatedly purchase connectors due to vehicle compatibility issues, effectively reducing parts waste and lowering user operating and maintenance costs. It also aligns with the concepts of green environmental protection and resource conservation, meeting the needs of sustainable development. Furthermore, the adjustable and replaceable connector design provides diverse options for the installation of frame components.
