Description

Technical Field

[0001] This utility model belongs to the field of controller housing technology, specifically relating to an integrated motor controller housing. Background Technology

[0002] With the continuous development of motor technology, the motor controller, as a core component of the motor system, has a crucial impact on the efficiency and stability of the entire system due to its performance and reliability. The design of the motor controller not only needs to meet the requirements of efficient power conversion and control functions, but also needs to consider many aspects such as heat dissipation, structural strength, ease of maintenance, and connection stability with the motor.

[0003] The motor controller is responsible for regulating the motor's operating status, including starting, stopping, speed control, and direction control. With the expansion of motor applications, especially in industrial automation, electric vehicles, and smart devices, the performance requirements for motor controllers are becoming increasingly demanding. A high-efficiency motor controller can significantly improve motor efficiency, extend its lifespan, and reduce energy consumption.

[0004] Motor controllers need to be electrically connected to motors and other external devices, and the stability of these connections directly affects the reliability of the system. Traditional connection methods may suffer from poor contact or weak connections, leading to electrical faults. Therefore, designing an integrated connection terminal not only simplifies the connection process but also improves connection reliability, making it an important consideration in current motor controller design.

[0026] Figure 3 This is a schematic diagram of the overall structure of the second embodiment of this utility model;

[0027] Figure 4 This is a schematic diagram of the overall structure of the third embodiment of this utility model. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figure 1 , Figure 2 As shown, this utility model embodiment provides an integrated motor controller housing, including a controller housing body 1 and a connection terminal 2 located at the outer end of the controller housing body 1.

[0030] The controller housing body 1 has a cavity structure inside to accommodate the controller, which is used to support the controller. At this time, the controller housing body 1 forms a whole. This design can ensure the external strength of the controller housing body 1. At the same time, this integrated design helps to improve the durability and resistance to external forces of the controller.

[0031] Multiple sets of parallel-arranged main heat sinks 3 are arranged at the end of the controller housing 1, forming a main heat dissipation airflow 301 between adjacent sets of main heat sinks 3. This design of the main heat dissipation airflow 301, which faces in one direction, facilitates the rapid flow of hot air and enables rapid cooling of the main heat sinks 3. Furthermore, the upper surfaces of the main heat sinks 3 are flush, ensuring the aesthetic appeal of the overall design.

[0032] A window 101 is provided on one side of the side wall where the controller housing body 1 is located. An openable cover plate (not shown in the figure) is provided on the window 101. After the controller housing body 1 is installed and fixed, it is directly connected to the controller inside the controller housing body 1 through the window 101. Therefore, when the controller has a partial fault, it will be directly connected and fixed to the controller through the window 101. A connector mounting position 102 is provided on the opposite side of the window 101; that is, the window 101 and the connector mounting position 102 are symmetrical on the end face of the controller housing body 1, which improves the symmetry and aesthetics of the structure.

[0033] A connection terminal 2 is provided on the connector mounting position 102. The connection terminal 2 has positive and negative terminal connectors 201, and the inner side of the positive and negative terminal connectors 201 is connected to the controller (i.e., forming an electrical connection), while the outer side extends outward to form an external plug-in connection for connection with external power supply or electrical appliances.

[0034] Multiple sets of horizontally parallel auxiliary heat sinks 4 are arranged on the circumferential outer wall of the controller housing 1, forming an auxiliary heat dissipation air duct 401 between adjacent sets of auxiliary heat sinks 4, with the auxiliary heat dissipation air duct 401 arranged in a horizontal direction. The directional design of the main heat dissipation air duct 301 and the auxiliary heat dissipation air duct 401 improves heat dissipation efficiency and ensures temperature control of the motor when it is working under high load.

[0035] Several sets of connection holes 111 are provided at the top of the inner cavity where the controller housing body 1 is located, and the multiple sets of connection holes 111 are distributed in an asymmetrical state, and are locked to the built-in controller bolts through the connection holes 111.

[0036] A vertical mounting hole 112 is provided on the outer edge of the cavity where the controller housing body 1 is located, and the mounting holes 112 are evenly distributed on the outer edge of the cavity. Through the mounting hole 112, it can be directly connected and fixed to the motor where the controller is located, ensuring that the controller housing body 1 where the mounting hole 112 is located is firmly fixed to the motor to be installed.

[0037] like Figure 3 As shown, the positive and negative terminals 201 are integrated and molded as a single piece. In this case, the connecting terminal 2 can directly penetrate through an opening in the side wall of the controller housing 1. When the positive and negative terminals of the positive and negative terminals 201 are two independent sets, two through holes need to be made in the side wall of the controller housing 1 for the positive and negative terminals to pass through. That is, in actual use, only one set of molds needs to be processed for the controller housing 1, and then separate turning holes need to be made for the through holes of the positive and negative terminals 201. This provides better adaptability and is suitable for small-scale mass production and R&D.

[0038] like Figure 4As shown, there is also a new design for the positive and negative terminal connectors 201, in which a locking connection is formed on the outside of the positive and negative terminal connectors 201 via a male and female connector. This application considers different connection methods and component configurations for different application scenarios, facilitating future maintenance and upgrades. Furthermore, the design trend of the motor controller adopted in this application is towards modularity, integration, and intelligence. Modular design provides greater flexibility, facilitating future maintenance and upgrades; integrated design reduces the number of components and improves the overall system performance; intelligence means that the controller can self-adjust based on real-time data to optimize the motor's operating state.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
