Description

Technical Field

[0001] This utility model relates to the field of automotive rectifier technology, specifically a lightweight integrated chip-type automotive rectifier. Background Technology

[0002] Traditional rectifiers on the market today have complex structures, mainly composed of components such as a positive plate, bridge support, negative plate, positive diode, negative diode, output screw, and mounting screw. Due to the large number of components, the assembly process for traditional rectifiers is cumbersome, and material control is extremely complex, making platform standardization difficult. This leads to a significant increase in labor, material, and management costs, gradually causing them to lose competitiveness in the market.

[0003] Traditional rectifiers cannot meet the requirements of both lightweight design and high power. When the motor power is very high, traditional rectifiers are limited by the space of the press-fit diodes and have difficulty meeting the heat dissipation requirements while ensuring small size and lightweight design. At present, traditional rectifiers mainly meet the heat dissipation requirements by making the heat sink plate larger, which leads to a sharp increase in development costs.

[0004] To address this, a lightweight integrated chip-based automotive rectifier is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight integrated chip-type automotive rectifier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight integrated chip automotive rectifier, including a heat sink, a busbar mounted on one side of the heat sink, an integrated circuit board mounted between the busbar and the heat sink, the pins of the integrated circuit board being soldered to the busbar, and an insulating plate mounted on one side of the busbar.

[0007] Preferably, the heat sink is fitted with an output screw using an interference fit.

[0008] Preferably, the outer side of the insulating plate is provided with a contouring auxiliary platform and a dustproof ring.

[0009] Preferably, the surface of the insulating plate is uniformly provided with supporting ribs and insulating platforms.

[0010] Preferably, the busbar has uniformly spaced connection holes, which are soldered to the pins of the integrated circuit board.

[0011] Preferably, the outside of the busbar is provided with an E-end, and a grounding stake is installed on the E-end.

[0012] Preferably, a thermally conductive material is provided between the integrated circuit board and the heat sink.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. It overturns the traditional rectifier structure and is mainly composed of: heat sink, busbar, mounting screw, output screw, integrated chip circuit board assembly and insulating board. It integrates traditional diodes into the integrated chip circuit board assembly, reducing the number of parts and facilitating production line assembly.

[0015] 2. Facilitates standardized product management by integrating positive and negative diodes into an integrated chip circuit board assembly. The circuit board assembly has a unified structure, which can be directly reused by subsequent products. Through integration, the negative electrode plate required for the original press assembly can also be removed, and it can be connected to the motor housing through a busbar.

[0016] 3. Compared with traditional automotive rectifiers, it has better heat dissipation efficiency, can achieve higher power while meeting lightweight design requirements. The new integrated chip automotive rectifier connects the integrated chip circuit board assembly and the heat sink with thermally conductive materials. After assembly, the integrated chip circuit board assembly directly contacts the heat sink, reducing thermal resistance during heat conduction. Without reducing the overall power, the space required for the heat sink can be greatly reduced. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6This utility model provides a technical solution: a lightweight integrated chip automotive rectifier, including a heat sink 4, a busbar 2 installed on one side of the heat sink 4, an integrated circuit board 3 installed between the busbar 2 and the heat sink 4, the pins of the integrated circuit board 3 being soldered to the busbar 2, and an insulating plate 1 installed on one side of the busbar 2.

[0026] like Figure 1 and Figure 5 As shown: The heat sink 4 is fitted with an output screw 5 using an interference fit.

[0027] like Figure 2 and Figure 3 As shown: The outer side of the insulating plate 1 is provided with a contouring auxiliary platform 11 and a dustproof ring 14; through the above settings, the contouring auxiliary platform 11 structure on the insulating plate 1 effectively reduces the wear of the stator wires and also plays a role in dust prevention and sealing. The addition of a dustproof ring 14 on the outside plays a role in reinforcement and dust prevention, reduces the isolation between the positive electrode plate and the end cover, and prevents short circuits.

[0028] like Figure 2 and Figure 3 As shown: The surface of the insulating board 1 is uniformly provided with supporting ribs 13 and insulating platforms 12; through the above arrangement, the insulating board 1 uses the insulating platform 12 to separate the circuit and the end cover to prevent short circuits. By using the supporting rib 13 structure and the busbar 2 in combination, the reliability of the product is increased.

[0029] like Figure 4 As shown: Connecting holes 21 are evenly distributed on the busbar 2. The connecting holes 21 are soldered to the pins of the integrated circuit board 3. With the above arrangement, the pins are inserted into the interior of the connecting holes 21 and then soldered together with the connecting holes 21, so that the integrated circuit board 3 and the busbar 2 can be connected together for easy use.

[0030] like Figure 4 As shown: The outer side of the busbar 2 is provided with an E terminal 22, and a grounding stake 23 is installed on the E terminal 22; through the above settings, the busbar 2 integrates an E terminal 22, which is connected to the grounding stake 23, eliminating the need for a negative electrode plate, reducing the number of parts, thereby optimizing the product assembly process and reducing development and labor costs.

[0031] like Figure 1 As shown: A thermally conductive material, namely silicone grease, is provided between the integrated circuit board 3 and the heat sink 4; through the above arrangement, the efficiency of heat transfer can be improved, and the heat dissipation efficiency can be improved.

[0032] Working Principle: The lightweight integrated chip-type automotive rectifier overturns the structural limitations of traditional rectifier products. It integrates the positive and negative diodes onto an integrated circuit board 3, resulting in a unified component structure that facilitates management and maintenance. Through integration, the negative electrode plate required for traditional press-fitting can be eliminated. Connected via a busbar 2, which integrates an E terminal 22 and connects to a grounding terminal 23, one negative electrode plate is eliminated, reducing the number of components and optimizing the product assembly process, thus lowering development and labor costs. Furthermore, the busbar 2 uses a contoured structure to effectively isolate the E terminal 22 from the positive electrode plate, effectively preventing short circuits.

[0033] To solve the problem of lightweight high-power rectifiers currently on the market, the diodes are integrated into the integrated circuit board 3 component, which greatly reduces the space required for the heat sink 4 without reducing the overall power.

[0034] To address the current market problem of poor rectifier reliability, the new integrated chip-type automotive rectifier offers higher reliability in installation and positioning. Without reducing overall power, it significantly improves vibration resistance. Simultaneously, the addition of an insulation plate 1 reduces the need to isolate the positive plate from the end cap, eliminating short circuits. The insulation plate 1 utilizes a contoured auxiliary platform 11 structure, effectively reducing stator wire wear and providing a dustproof seal. Furthermore, the insulation plate 1 employs an isolation platform 12 to separate the wiring from the end cap, preventing short circuits. The use of support ribs 13 and the busbar 2 further enhances product reliability. An additional dustproof ring 14 reinforces the outer layer and provides dust protection, further reducing the need to isolate the positive plate from the end cap and eliminating short circuits.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
