Description

Technical Field

[0001] The present application relates to the technical field of electric control connection components for electric vehicles, and particularly to a connection structure for the electric control three-phase copper busbar of a transmission box motor. Background Art

[0002] Currently, in the structure of the transmission box, the connection method between the motor and the three-phase copper busbar of the electric control system generally adopts an indirect connection method, and this solution relies on a specific component - a high-voltage wiring seat (hereinafter referred to as the "intermediate component") to achieve current transduction. Specifically, the copper busbar on the motor side is tightly connected to one end of the intermediate component through a copper busbar, and the copper busbar on the electric control system side is docked to the other end of the intermediate component, thereby establishing an electrical path between the motor and the electric control. Although this connection method realizes the basic functional requirements, it also reveals several potential problems and limitations.

[0003] The primary problem lies in its heavy dependence on the intermediate component. As the necessary bridge for current transmission, the performance and state of the intermediate component directly determine the working reliability of the entire system. Once the intermediate component fails or is damaged, the current transmission chain will be interrupted, leading to system failure, which undoubtedly significantly increases the risk factors and maintenance costs of the system. Therefore, any instability of the intermediate component may become a hidden danger in the system operation, reducing the overall stability and reliability.

[0004] Secondly, the existence of the intermediate component also inevitably introduces losses in current transmission efficiency. During the process of current transfer through the intermediate component, certain energy losses will occur due to factors such as contact resistance and material properties. This is undoubtedly an adverse factor for application scenarios that pursue high efficiency and low energy consumption. Especially in high-power transmission systems, even a small efficiency loss may accumulate into significant energy waste, affecting the overall performance of the system.

[0005] In addition, the design complexity and manufacturing cost of the intermediate component cannot be ignored. To meet the requirements of the transfer function, the intermediate component usually requires a dual-end copper busbar design, which not only results in a relatively large volume, occupying more space, but also means higher material consumption and processing costs. In the current trend of pursuing miniaturization, lightweight, and cost optimization, such a design seems out of place, restricting the improvement of the integration level and cost control potential of the transmission system.

[0006] In summary, although the existing indirect connection method of the motor electric control copper busbar realizes basic current transmission through the intermediate component, its dependence on the intermediate component, efficiency loss, and cost issues have become important bottlenecks restricting the performance upgrade of the transmission system.

[0007] Therefore, there is an urgent need to provide a connection structure for the electric control three-phase copper busbar of a transmission box motor to solve the above-mentioned technical problems. Summary of the Invention

[0008] Based on this, a connection structure for the three-phase copper busbars of the motor and electronic control in the transmission case is provided, which fundamentally solves the drawbacks brought by relying on traditional high-voltage connection seats. By directly connecting the motor copper busbar and the electronic control copper busbar, the intermediate transfer link is bypassed, significantly reducing the system fault points and improving the reliability and efficiency of current transmission; and there is no need for complex copper busbar transfer design, simplifying the manufacturing process and material requirements, controlling the production cost from the source, and improving the cost-benefit ratio.

[0009] To solve the above problems, the present application provides a connection structure for the three-phase copper busbars of the motor and electronic control in the transmission case, including: a support seat detachably installed on the transmission case housing; a connecting member that directly connects and fixes the motor copper busbar and the electronic control copper busbar on the support seat.

[0010] Preferably, three stacked areas are arranged side by side on the support seat; the electronic control copper busbar and the motor copper busbar are stacked up and down in the stacked areas and are connected and fixed by the connecting member.

[0011] Preferably, the connecting member includes a connecting bolt, and connecting threaded holes corresponding to the connecting bolt are provided in the stacked areas.

[0012] Preferably, side bosses are respectively arranged on opposite sides of the stacked areas; the motor copper busbar and the electronic control copper busbar are positioned between the side bosses on both sides.

[0013] Preferably, a bottom boss is provided at the connection between the side boss and the bottom wall of the stacked area; the motor copper busbar fits against the bottom wall of the stacked area and is positioned at the front end of the bottom boss; the electronic control copper busbar is stacked on the motor copper busbar.

[0015] Preferably, the installation member includes an installation bolt, and installation threaded holes corresponding to the installation bolt are provided in the installation area.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Therefore, it cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] The embodiment of the present application provides a connection structure for the motor electric control three-phase copper busbar of the transmission case, which fundamentally solves the drawbacks brought by relying on the traditional high-voltage terminal block (intermediate component), realizes the direct connection between the motor copper busbar and the electric control copper busbar, thereby bypassing the intermediate transfer link, significantly reducing the system fault points, and improving the reliability and efficiency of current transmission.

[0033] The following will describe in detail a connection structure for the motor electric control three-phase copper busbar of the transmission case provided in this embodiment with reference to the Figure 1 、 Figure 2 shown in the figure, including: a support seat 1 and a connecting piece 2. The support seat 1 is detachably installed on the transmission case housing 5, and the connecting piece 2 is used to directly connect and fix the motor copper busbar 3 and the electric control copper busbar 4 on the support seat 1.

[0034] In this embodiment, in the structure of the transmission case, the traditional method of using an intermediate component to connect the motor copper bar 3 and the electric control copper bar 4 is abandoned. Instead, the motor copper bar 3 and the electric control copper bar 4 are directly connected and fixed to the support base 1 by using the connecting member 2. This direct connection design eliminates the potential failure points that may be brought by the traditional intermediate component, greatly enhances the stability of current transmission and the overall reliability of the system, reduces the risk of shutdown caused by the failure of the intermediate component, and ensures the safety of continuous operation. At the same time, the additional resistance generated when the current passes through the intermediate component is removed, effectively reducing the energy loss and improving the current transmission efficiency. This not only means that the response of the power system is faster, but also optimizes the energy use and reduces the operating cost.

[0035] Please refer to Figure 2 、 Figure 3 As shown, in this embodiment, it should be noted that there are three stacked areas 11 arranged side by side on the support base 1. The electric control copper bar 4 and the motor copper bar 3 are stacked up and down in the stacked area 11 and are connected and fixed by the connecting member 2. Through the setting of the stacked area 11, when connecting, the motor copper bar 3 and the electric control copper bar 4 can be stacked in the stacked area 11 to complete the preliminary connection. Subsequently, the motor copper bar 3 and the electric control copper bar 4 are stably fixed in the stacked area 11 by the connecting member 2, so that the direct connection between the motor copper bar 3 and the electric control copper bar 4 can be realized. This connection design method can ensure that the current can flow smoothly from the motor to the electric control, effectively reducing the resistance loss caused by the intermediate link and promoting the efficient transmission of the current. At the same time, this connection method does not require a complex copper bar transfer design, simplifies the manufacturing process and material requirements, controls the production cost from the source, and improves the cost-benefit ratio.

[0036] In some embodiments, the connecting member 2 includes a connecting bolt, and there are connecting threaded holes 111 corresponding to the connecting bolts in the stacked area 11. By using the cooperation of the connecting bolt and the connecting threaded hole 111, it is convenient to disassemble and assemble the motor copper bar 3 and the electric control copper bar 4, and the connection stability is high.

[0037] Please refer to Figures 2 - 5 As shown, in this embodiment, it should also be noted that side bosses 12 are respectively arranged on the opposite sides of the stacked area 11. The motor copper bar 3 and the electric control copper bar 4 are positioned between the side bosses 12 on both sides. By setting the two side bosses 12, the positions of the motor copper bar 3 and the electric control copper bar 4 will not deviate during installation, which is convenient for the connecting bolt to pass through the corresponding holes and connect with the connecting threaded hole 111. During installation, the motor copper bar 3 fits on the bottom of the stacked area 11, and the electric control copper bar 4 is stacked on the motor copper bar 3.

[0038] In some embodiments, a bottom boss 13 is provided at the connection between the side boss 12 and the bottom wall of the stacking area 11. The motor copper bar 3 is attached to the bottom wall of the stacking area 11 and positioned at the front end of the bottom boss 13. By providing the bottom boss 13, when the motor copper bar 3 is attached to the bottom wall of the stacking area 11 during installation, it can abut against the front end of the bottom boss 13, thereby realizing the positioning of the position of the motor copper bar 3, aligning the hole positions with the connecting threaded holes 111, and facilitating the connecting bolts to pass through the corresponding hole positions and connect with the connecting threaded holes 111.

[0039] Please refer to Figure 1 、 Figure 3 As shown, in this embodiment, it should also be noted that an installation area 14 is provided between two adjacent stacking areas 11. An installation member 6 is provided in the installation area 14, and the installation member 6 is used to install the support base 1 on the transmission case housing 5. By providing the installation area 14, it is convenient to install the support base 1 on the transmission case housing 5 through the installation member 6.

[0040] In some embodiments, the installation member 6 includes an installation bolt, and installation threaded holes 141 corresponding to the installation bolts are provided in the installation area 14. By using the cooperation of the installation bolts and the installation threaded holes 141, the disassembly and assembly operations of the support base 1 are convenient, and the connection stability is high.

[0041] In this embodiment, it should also be noted that the support base 1 is made of plastic insulation material and does not require a complex copper bar transfer design, and can be made into a compact type. Compared with traditional intermediate parts, the support base 1 focuses on the physical support function, can reduce the volume and cost, no longer bears the current transfer task, and optimizes the cost-effectiveness.

[0042] The implementation principle of this embodiment: Abandon the traditional indirect connection mode, and cleverly use the compact support base 1. The support base 1 has a streamlined volume and significantly improved cost-effectiveness. Its design focuses on providing stable physical support rather than being an essential link for current transfer. By directly fixing the motor copper bar 3 and the electric control copper bar 4 on the support base 1 with connecting bolts, it ensures that the current can flow smoothly from the motor to the electric control, effectively reducing the resistance loss caused by intermediate links and promoting the efficient transmission of current. In addition, this design also focuses on simplifying the assembly process and maintenance convenience, improving the integration degree of the overall system, and reducing the energy consumption and potential maintenance cost during long-term operation. In summary, this innovative connection solution realizes a more direct, efficient and economical current connection method by removing redundant links in current transmission, and sets a new standard for the performance and reliability of the transmission system.

[0043] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
