Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor controller protection technology, and specifically relates to a protection structure for motor controllers. Background Technology
[0002] A motor controller is a crucial device in the operation of a motor. It possesses a high degree of intelligence and precision. The motor controller can precisely control parameters such as motor speed, direction of rotation, and torque to meet the needs of different application scenarios. Through advanced electronic technology and algorithms, it can monitor the motor's operating status in real time and make dynamic adjustments based on actual conditions, ensuring that the motor always operates in optimal condition.
[0003] Chinese patent CN219248291U discloses a medical high-speed DC motor controller with a protective structure. The specification describes a method where the motor controller body of the high-speed DC motor is installed inside a protective cover. The protective cover protects the motor controller body, reducing the impact of external factors such as dust on the motor controller body. A buffer seat is provided to cushion the motor controller body, preventing loose wiring and damage to internal components due to the buffering. At the same time, a filter plate is provided to reduce the impact of dust on the controller. The use of an electromagnetic plate and a magnetic plate together allows the dust attached to the filter plate to fall off, preventing blockage and affecting the heat dissipation of the controller. This solves the problem of poor protection effect of previous medical high-speed DC motor controllers.
[0004] However, the aforementioned application involves storing the controller in a protective enclosure, but this method has limitations in terms of heat dissipation. Specifically, relying solely on ventilation holes in the side wall of the enclosure for heat dissipation is insufficient due to its limited cooling pathway. Therefore, most of the heat remains trapped inside the enclosure and is difficult to dissipate quickly. Utility Model Content
[0005] The purpose of this invention is to provide a protective structure for motor controllers to solve the problem that existing controller protective structures have poor heat dissipation performance.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A protective structure for a motor controller includes a housing, inside which a controller body is located. A door is installed on the surface of the housing. An auxiliary mechanism is located inside the housing. The auxiliary mechanism includes a heat-conducting pipe disposed inside the housing. Multiple heat-conducting rods are fixedly connected to the arc surface of the heat-conducting pipe. A heat-conducting plate is fixedly connected to the top of the multiple heat-conducting rods. Multiple heat sinks are fixedly connected to the end face of the heat-conducting plate.
[0008] Preferably, the heat pipe has a continuous U-shaped cross-section, and the heat pipe, heat rod, and heat plate are all made of copper.
[0009] Preferably, two rectangular blocks are fixedly connected inside the housing, the bottom surface of the controller body is in contact with the end faces of the two rectangular blocks, a hole is provided at the bottom of the housing, and a filter screen is installed inside the hole.
[0010] Preferably, the side wall of the box has a rectangular hole, a fixing block is fixedly connected to the side wall of the box, and a round rod is fixedly connected to the surface of the fixing block.
[0011] Preferably, multiple dustproof pads are fixedly connected to both sides of the inner wall of the rectangular hole, and the dustproof pads are rubber pads.
[0012] Preferably, a square plate is fixedly connected to the side wall of the fixing block, a rotating rod is rotatably connected to the end face of the square plate, a pressure plate is fixedly connected to the arc surface of the rotating rod, and the pressure plate is located above the round rod.
[0013] Preferably, a pad is fixedly connected to the bottom surface of the pressure plate, and the pad is a sponge pad.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, by incorporating heat pipes, heat sinks, and heat-conducting rods, and utilizing the continuous U-shaped structure of the heat pipes, significantly increases their contact area with the air. Compared to traditional linear heat pipes, it allows for greater contact with the surrounding air within the same space. This enables more heat to be efficiently conducted away from the enclosure. Simultaneously, the large contact area between the heat sinks and the air allows them to quickly absorb the heat conducted by the heat pipes and dissipate it into the surrounding air, thereby lowering the temperature inside the enclosure and creating a suitable working environment for the controller's normal operation.
[0016] 2. This utility model uses a dustproof pad, a rectangular hole, a round rod, and a pad plate. The design of the rectangular hole can improve the ventilation effect inside the box. The arrangement of multiple dustproof pads can effectively prevent dust from entering the box through the rectangular hole. The use of the round rod provides great convenience for winding up the wires on the controller. Attached Figure Description

[0023] 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.
[0024] Reference Figures 1-5 As shown, this utility model provides a protective structure for a motor controller, including a housing 1. The housing 1 has a controller body 11 inside, a door 12 installed on the surface of the housing 1, and an auxiliary mechanism 2 inside the housing 1. The auxiliary mechanism 2 includes a heat-conducting pipe 21 disposed inside the housing 1. Multiple heat-conducting rods 22 are fixedly connected to the arc surface of the heat-conducting pipe 21. A heat-conducting plate 23 is fixedly connected to the top of the multiple heat-conducting rods 22. Multiple heat sinks 24 are fixedly connected to the end face of the heat-conducting plate 23.
[0025] In this embodiment, when the heat generated by the controller body 11 during use is distributed in the housing 1, the heat pipe 21 will absorb the heat. Liquid or gas can be introduced into the heat pipe 21 to improve the heat dissipation effect. The heat absorbed by the heat pipe 21 will be conducted to the heat plate 23 by the heat rod 22, and then the heat sink 24 will come into contact with the air to dissipate the heat, thereby improving the heat dissipation effect of the controller body 11 in the housing 1.
[0026] The heat pipe 21 has a continuous U-shaped cross-section. The heat pipe 21, heat rod 22 and heat plate 23 are all made of copper, which has better thermal conductivity.
[0027] In this embodiment, the heat pipe 21 has a continuous U-shaped cross-section, which significantly increases its contact area with air. Compared to the traditional straight type, it can have a greater degree of contact with the surrounding air within the same space.
[0028] Two rectangular blocks 13 are fixedly connected inside the housing 1. The bottom surface of the controller body 11 is in contact with the end faces of the two rectangular blocks 13. A hole is opened at the bottom of the housing 1, and a filter screen 25 is installed inside the hole.
[0029] In this embodiment, the controller body 11 can be supported by the rectangular block 13, thus providing a larger heat dissipation space at the bottom.
[0030] A rectangular hole 26 is provided on the side wall of the box body 1, and a fixing block 27 is fixedly connected to the side wall of the box body 1. A round rod 28 is fixedly connected to the surface of the fixing block 27.
[0031] In this embodiment, the use of the round rod 28 greatly facilitates the winding of excessively long wires on the controller body 11.
[0032] Multiple dustproof pads 29 are fixedly connected to both sides of the inner wall of the rectangular hole 26. The dustproof pads 29 are rubber pads.
[0033] In this embodiment, the arrangement of multiple dust-blocking pads 29 can effectively prevent dust from entering the housing 1 through the rectangular hole 26.
[0034] A square plate 210 is fixedly connected to the side wall of the fixed block 27. A rotating rod 211 is rotatably connected to the end face of the square plate 210. A pressure plate 212 is fixedly connected to the arc surface of the rotating rod 211. The pressure plate 212 is located above the round rod 28. A pad 213, which is a sponge pad, is fixedly connected to the bottom surface of the pressure plate 212.
[0035] In this embodiment, by rotating the pressure plate 212, the pad 213 is positioned above the wire, thereby limiting the wire on the round rod 28. The pad 213 is a sponge pad that serves to protect the wire.
[0036] The working principle of this utility model is as follows: During use, the operator places the controller body 11 on two rectangular blocks 13, creating a gap at the bottom of the controller body 11 to improve ventilation. The wires on the controller body 11 can be pulled out from the rectangular hole 26. For excessively long wires, they can be wound around the round rod 28 to tidy them up. After winding, the pressure plate 212 can be rotated to position the pad 213 above the wires, limiting the wires on the round rod 28. The dustproof pad 29 at the rectangular hole 26 serves to block dust. During use, when the heat generated by the controller body 11 is distributed in the housing 1, the heat pipe 21 absorbs the heat. Liquid or gas can be introduced into the heat pipe 21 to improve the heat dissipation effect. The heat absorbed by the heat pipe 21 is conducted to the heat plate 23 by the heat rod 22, and then dissipated by the heat sink 24 in contact with the air, thereby improving the heat dissipation effect of the controller body 11 in the housing 1.
[0037] 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.
