Description

Technical Field

[0001] This utility model relates to the field of motor controller technology, specifically a DC brushless motor controller. Background Technology

[0002] A motor controller is an integrated circuit that actively controls a motor to operate in a set direction, speed, and response time. A brushless motor controller is a control device that can provide a closed-loop commutation control signal for a three-phase brushless motor. It can also control the motor speed and provide necessary protection for the motor using various modes.

[0003] Existing motor controllers have wiring ports on their housings for cable connections, and typically use a sealing ring at the wiring port for waterproofing. However, prolonged use can cause the sealing ring to loosen, leading to a decrease in waterproofing effectiveness. Therefore, a DC brushless motor controller has been proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a DC brushless motor controller to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a DC brushless motor controller, comprising: A controller housing for mounting the controller; Multiple wire-passing holes are located on the lower part of the controller housing to provide a channel for the cables for wiring the controller. Each of the multiple wire-passing holes is movably connected to a sealing cover, and the sealing cover is interference-fitted with the wire-passing hole. Multiple limiting components are provided, all of which are located below the outer cover of the controller housing. The limiting components are used to limit the movement of the cover.

[0006] Furthermore, the limiting component includes a support shaft, which is rotatably connected to the lower part of the controller housing. A connecting plate is fixedly connected to the bottom outer surface of the support shaft, a spring is fixedly connected to the top outer surface of the connecting plate, and a top block is fixedly connected to the top outer surface of the spring.

[0007] Furthermore, the bottom outer surface of the controller housing is provided with several heat dissipation holes, through which the heat generated inside the controller housing is discharged.

[0008] Furthermore, a dustproof component is provided on the outer surface of the controller housing outside the heat dissipation holes. The dustproof component is used to prevent dust in the air from entering the interior of the controller housing.

[0009] Furthermore, the dustproof component includes a fixing frame located on the outer surface of the controller housing outside the heat dissipation holes. A dustproof frame is provided on the outside of the fixing frame, and a dustproof mesh is installed inside the dustproof frame.

[0010] Furthermore, the fixing frame is a magnetic frame, and the dustproof frame is an iron frame.

[0011] Furthermore, a top cover is bolted to the top outer surface of the controller housing, and sealing gaskets are installed at the four bottom corners of the top cover.

[0013] Furthermore, the outer surface of the sealing cover is provided with a receiving groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets the wire hole at the bottom of the controller housing and allows wires to be threaded through the wire hole. The connecting plate, spring and top block lift the cover at the sealing block, thus placing the wire hole at the bottom of the controller housing.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0019] Please refer to the following: Figures 1-7 This utility model provides a technical solution: a DC brushless motor controller, including a controller housing 100, multiple wiring holes 101, and multiple limiting components. The controller housing 100 is used to install the controller. The multiple wiring holes 101 are all located below the controller housing 100 and are used to provide channels for the cables connecting the controller. Each of the multiple wiring holes 101 is movably connected to a sealing cover 200, which is interference-fitted with the wiring hole 101. The multiple limiting components are all located below the sealing cover 200 outside the controller housing 100 and are used to limit the sealing cover 200. Specifically, the controller and other electrical components are installed inside the controller housing 100, and the wiring is done through the wiring holes 101. The wiring holes 101 are closed by the sealing cover 200, and the limiting components make the sealing cover 200 stably located inside the wiring hole 101.

[0020] Furthermore, the limiting component includes a support shaft 300, which is rotatably connected to the lower part of the controller housing 100. A connecting plate 301 is fixedly connected to the bottom outer surface of the support shaft 300, and a spring 302 is fixedly connected to the top outer surface of the connecting plate 301. A top block 303 is fixedly connected to the top outer surface of the spring 302. Specifically, the limiting component limits the closing cover 200. At this time, force is applied to the connecting plate 301, causing the connecting plate 301 to drive the support shaft 300 to rotate, causing the top block 303 to rotate to the closing cover 200. Below, when the top block 303 contacts the bottom of the closing cover 200, the closing cover 200 presses the inclined edge of the top block 303, causing the spring 302 to deform until the positioning block is located below the closing cover 200. The elastic force of the spring 302 drives the closing cover 200 to support the closing cover 200, increasing the stability of the closing cover 200. This allows the wire hole 101 to be located below the controller housing 100, preventing rainwater from entering the interior of the controller housing 100 through the wire hole 101 and causing damage to the components inside the controller housing 100.

[0021] Furthermore, a number of heat dissipation holes 102 are provided on the bottom outer surface of the controller housing 100. The heat generated inside the controller housing 100 is discharged through the heat dissipation holes 102. Specifically, the heat generated by the electrical components inside the controller housing 100 during operation is discharged through the heat dissipation holes 102.

[0022] Furthermore, a dustproof component is provided on the outer surface of the controller housing 100 outside the heat dissipation hole 102. The dustproof component is used to prevent dust in the air from entering the interior of the controller housing 100.

[0023] Furthermore, the dustproof component includes a fixing frame 500, which is located on the outer surface of the controller housing 100 outside the heat dissipation hole 102. A dustproof frame 501 is provided outside the fixing frame 500, and a dustproof net 502 is installed inside the dustproof frame 501. Specifically, the dustproof net 502 isolates impurities in the air and prevents impurities from entering the interior of the controller housing 100 through the heat dissipation hole 102.

[0024] Furthermore, the fixing frame 500 is a magnetic frame, and the dustproof frame 501 is an iron frame. Specifically, the iron frame is attracted by the magnetic frame. When the dustproof net 502 needs to be disassembled for cleaning, the iron frame is removed from the magnetic frame, the dustproof frame 501 is removed, and the dustproof net 502 is cleaned.

[0025] Furthermore, a top cover is bolted to the top outer surface of the controller housing 100, and sealing gaskets are installed at the four corners of the bottom of the top cover. Specifically, by removing the top block 303, space is provided for the installation and wiring of electrical components inside the controller housing 100, and the sealing gaskets increase the sealing between the top cover and the controller housing 100.

[0026] Furthermore, the top of the top block 303 has an inclined outer surface, and a movable rod is fixedly connected to the bottom outer surface of the top block 303. The movable rod moves through the connecting plate 301. Specifically, when the top block 303 moves, the movable rod slides within the connecting plate 301 to guide the movement of the top block 303, so that the top block 303 moves stably in a straight line. By setting the inclined surface of the top block 303, when the top block 303 contacts the closing cover 200, the closing cover 200 can squeeze the top block 303 to deform the spring 302.

[0027] Furthermore, the outer surface of the cover 200 is provided with a receiving groove 201, specifically, the receiving groove 201 provides space for the cable to pass through the cover 200.

[0028] Working Principle: In use, the controller is installed inside the controller housing 100. The cover is then opened, and the controller is wired through the wire hole 101. Opening the cover provides space for wiring. After wiring, the closing cover 200 closes the receiving groove 201, allowing the cable to pass through. The closing cover 200 is then limited by a limiting component. At this point, force is applied to the connecting plate 301, causing it to rotate the support shaft 300, thus rotating the top block 303 towards the closing cover 201. Below 0, when the top block 303 contacts the bottom of the closing cover 200, the closing cover 200 presses the inclined edge of the top block 303, causing the spring 302 to deform until the positioning block is located below the closing cover 200. The elastic force of the spring 302 drives the closing cover 200 to support the closing cover 200, increasing the stability of the closing cover 200. This allows the wire hole 101 to be set below the controller housing 100, preventing rainwater from entering the interior of the controller housing 100 through the wire hole 101 and causing damage to the components inside the controller housing 100.

[0029] The heat generated by the electrical components inside the controller housing 100 during operation is dissipated through the heat dissipation holes 102 and is isolated from impurities in the air by the dustproof net 502, preventing impurities from entering the interior of the controller housing 100 through the heat dissipation holes 102. When it is necessary to clean the dustproof net 502, the dustproof frame 501 can be directly removed from the fixed frame 500.

[0030] 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.
