Problems solved by technology

[0003] Existing BLDC control assemblies are all box-type structures, using side outlets, mainly relying on the ribs on the upper surface of the housing for heat dissipation, which has a large thermal resistance and poor effect, and its heat dissipation structure is not suitable for high-power BLDC control assemblies
[0004] On the other hand, the protection IP level of the existing BLDC control assembly is low, there is no waterproof ditch, and it cannot be effectively waterproof and dustproof, which is the reason why the BLDC control assembly often causes damage

Abstract

The invention discloses an integrated BLDC control assembly. The integrated BLDC control assembly comprises a base (1), an upper shield (2) and a direct current circuit breaker (7). A control assembly socket (3) and a plurality of binding posts are arranged on the upper surface of the upper shield (2), fins (5) are vertically and symmetrically arranged on the left side and the right side of the upper surface of the base (1), and the fins (5) and the base (1) are of an integrated aluminum profile structure. The direct current circuit breaker (7) and a PCB (8) are arranged between the fins (5) on the left side and the right side of the upper surface of the base. A plurality of VMOS power tube sets (9) are arranged on the side face, close to the fins (5), above the PCB (8), and pins of the VMOS power tube sets (9) are connected with the PCB (8) placed at the bottom of the base (1). Fuses (4) are arranged between the binding posts with the same polarity of the upper shield (2) and the direct current circuit breaker (7). According to the integrated BLDC control assembly, the fuses and the direct current circuit breaker are integrated, the fins, mounting ribs and the base are made to be of an integrated aluminum profile structure, a radiating effect is improved by more than 50%, and a dust poof and water proof function is excellent.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control assembly preparation, in particular to a BLDC control assembly with high protection level. Background technique [0002] BLDC is an acronym for Brushless DC motor, which means a permanent magnet brushless DC motor. Compared with series-excited brushed motors, BLDC is more and more widely used for its advantages of light weight, small size, good acceleration characteristics, low noise, high efficiency, and long life. [0003] Existing BLDC control assemblies are all box-type structures, using side outlets, mainly relying on the ribs on the upper surface of the housing for heat dissipation. The thermal resistance is large and the effect is not good. The heat dissipation structure is not suitable for high-power BLDC control assemblies. [0004] On the other hand, the protection IP level of the existing BLDC control assembly is low, there is no waterproof ditch, and it cannot be effe...
