[0002] With the increasing popularity of electric motorcycles, higher demands are being placed on the performance and reliability of their electronic control systems. The electronic control system of an electric motorcycle is a crucial component ensuring the normal operation of the vehicle; it needs to possess efficient current transmission capabilities while also guaranteeing stable operation under various environmental conditions. In the electric motorcycle's electronic control system, the mounting bracket, as a core component connecting multiple parts such as the PCB board, aluminum alloy end cover plate, and three-phase copper busbar, is of paramount importance in terms of structural stability. Traditional mounting methods may suffer from structural instability and susceptibility to environmental influences.

[0003] In the production, assembly, and subsequent maintenance of electric motorcycles, the ease and accuracy of mounting bracket installation are crucial factors for improving production efficiency and maintenance convenience. Current mounting brackets for electric motorcycle electronic controls suffer from problems such as complex installation and susceptibility to errors.

[0004] In addition, considering the harsh working environment of electric motorcycle control systems, including factors such as moisture and dust, as well as potential electrical problems caused by vibration and impact, improving the safety and reliability of electrical connections has become an urgent issue to be addressed.

[0005] In electric motorcycle control systems, the oxidation resistance and durability of metal components directly affect the long-term stable operation of the system. Especially in open-air environments, metal components are susceptible to oxidation, leading to a decline in electrical performance. Summary of the Invention

[0006] The purpose of this utility model is to provide a copper busbar plastic fixing base for electric motorcycles and electric controls, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar plastic fixing base for electric motorcycle control, comprising a PCB board, an aluminum alloy end cover plate, a three-phase copper busbar and a plastic fixing base. The three-phase copper busbar is connected side by side on the PCB board by screws to ensure effective current conduction. A plastic fixing base is provided on the lower end face of the PCB board. The copper nut on the plastic fixing base locks the three-phase copper busbar, the PCB board and the plastic fixing base together to form a stable and highly conductive overall structure.

[0008] Preferably, a set of anti-foolproof and anti-rotation positioning pins are provided on the plastic fixing base to improve the stability of the fixing base and the accuracy of installation.

[0009] Preferably, the aluminum alloy end cap is provided with symmetrical box mounting guide posts at the four corners, and the height of the guide posts is higher than the height of the electrical components on the PCB board.

[0010] Preferably, the anti-foolproof and anti-rotation positioning pin has a protrusion, and the plastic fixing seat has a matching groove.

[0011] Preferably, a tin layer is plated on the surface of the three-phase copper busbar to improve its oxidation resistance and the safety of the electrical connection.

[0012] Preferably, there are two anti-foolproof and anti-rotation positioning pins, symmetrically distributed on both sides of the plastic fixing base, to ensure the correct orientation and position of the fixing base during installation.

[0013] Preferably, a temperature sensor and an overcurrent protection device are provided on the PCB board to automatically disconnect the circuit when an abnormality is detected, thereby enhancing the safety of the entire system.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. The introduction of plastic mounting brackets, combined with the use of copper nuts, enhances the stability of the entire mounting bracket structure; the use of rubber materials helps absorb vibration and impact, improving the stability of operation under various environmental conditions.

[0016] 2. The design of the foolproof and anti-rotation positioning pin, which matches the groove on the plastic fixing base, ensures the correctness and stability of the fixing base installation and effectively prevents problems caused by incorrect installation.

[0017] 3. The enclosure mounting guide post design on the aluminum alloy end cap not only helps with the precise installation of the mounting bracket, but also provides additional protection because its height is higher than that of the electrical components on the PCB board.

[0018] 4. The foolproof and anti-rotation design, along with the guide post-guide hole combination, greatly simplifies the installation process and improves assembly efficiency. This design allows for accurate installation even in space-constrained or poorly oriented conditions.

[0019] 5. By tin-plating the surface of the three-phase copper busbar, not only is the oxidation resistance improved, but the safety of the electrical connection is also enhanced, reducing the risk of electrical problems caused by oxidation.

[0020] 6. By installing temperature sensors and overcurrent protection devices on the PCB board, the system operating status can be monitored in real time. When an abnormality is detected, the circuit can be automatically disconnected, effectively preventing damage caused by overheating and overload, and greatly improving the safety of the entire electrical control system.

[0026] In addition, the three-phase copper busbar 3 is specially designed with a reinforcing rib structure to improve the mechanical strength of the copper busbar, making it better able to withstand various stresses that the electric motorcycle may encounter during operation.

[0027] Furthermore, in addition to providing basic support and protection, the aluminum alloy end cover plate 5 is also designed with heat sinks, which helps to improve the heat dissipation efficiency of the entire electronic control system and ensure the safety of the electric motorcycle during long-term operation.

[0028] Furthermore, the anti-foolproof and anti-rotation positioning pin 6, in addition to ensuring the correctness and convenience of installation, is also made of a highly durable material, ensuring that it can maintain its functional effectiveness even in environments with frequent disassembly and assembly.

[0029] This invention optimizes structural design and selects materials to balance mechanical strength and electrical performance, ensuring reliable operation of the electric motorcycle's control system in complex environments. Through detailed design (such as anti-foolproof and anti-rotation mechanisms, and guide structures), it improves the product's ease of use and maintenance, reduces the possibility of incorrect installation, extends product lifespan, and lowers maintenance costs.
