Description

Technical Field

[0001] This utility model relates to the field of disc motors, and in particular to a heat dissipation and ventilation mechanism for disc motors. Background Technology

[0002] In the prior art, the heat dissipation and ventilation mechanism for disc motors mostly consists of heat dissipation fins fixedly installed on the disc motor housing, an external cooling fan, and ventilation channels set on the housing. These components together constitute the basic structure of the motor heat dissipation system.

[0003] In the existing technology, the process of using this mechanism is as follows: when the disc motor generates heat during operation, the heat is transferred through the motor casing to the fixed heat dissipation fins. At the same time, the external cooling fan is started, which causes air to flow through the surface of the heat dissipation fins and the ventilation channels. The air flow carries away the heat on the fins, thereby achieving heat dissipation and cooling of the motor.

[0004] In the prior art, the position of the heat dissipation fins is usually fixed and it is difficult to adjust them according to the difference in heat distribution between the inner and outer rings of the motor. Since the space near the central shaft of the inner ring of the disc motor is relatively small and is often occupied by components such as shafts and bearings, the heat transfer path is long. Moreover, the number of heat dissipation fins and the heat dissipation area in this area are relatively limited, making it difficult for the heat in the inner ring to dissipate and easily leading to temperature accumulation. Therefore, a heat dissipation and ventilation mechanism for disc motors has been proposed to address the above-mentioned problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat dissipation and ventilation mechanism for a disc motor, comprising a disc motor housing, a connector fixedly connected to the outer wall of the disc motor housing, a mounting bolt threadedly connected to the top of the disc motor housing, and a heat dissipation mechanism provided on the back of the disc motor housing;

[0007] The heat dissipation mechanism includes an inner ring of heat dissipation fins, the outer wall of which is fixedly connected to the outer wall of the disc motor housing. An outer ring of heat dissipation fins is fixedly connected to the outer wall of the disc motor housing. A sliding groove is formed on the outer wall of the disc motor housing. A movable heat dissipation fin is slidably connected to the inner wall of the sliding groove. A sliding rod is fixedly connected to the top of the movable heat dissipation fin. A limit block is fixedly connected to the top of the sliding rod. A fixing mechanism is provided on the outer wall of the disc motor housing.

[0008] As a further description of the above technical solution: the fixing mechanism includes a through plate, the inner wall of which is provided with an arc-shaped groove, the inner wall of which is slidably connected to the outer wall of the slide rod, and a spring is fixedly connected to the bottom of the through plate.

[0009] As a further description of the above technical solution: the inner wall of the through plate is fixedly connected with limiting teeth, and the outer wall of the through plate is fixedly connected with a handle.

[0010] As a further description of the above technical solution: a connecting column is fixedly connected to the outer wall of the disc motor housing, and teeth are fixedly connected to the outer wall of the connecting column.

Detailed Implementation

[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 1-3 This utility model provides an embodiment of a heat dissipation and ventilation mechanism for a disc motor, comprising a disc motor housing 1, a connector 2 fixedly connected to the outer wall of the disc motor housing 1, a mounting bolt 3 threadedly connected to the top of the disc motor housing 1, and a heat dissipation mechanism 4 provided on the back of the disc motor housing 1. The heat dissipation mechanism 4 includes inner ring heat dissipation fins 411, the outer wall of which is fixedly connected to the outer wall of the disc motor housing 1, and the inner ring heat dissipation fins 411 are located at the center end of the outer wall of the disc motor housing 1 for transferring heat from the inner ring. An outer ring heat dissipation fin 412 is fixedly connected to the outer wall of the disc motor housing 1 and is installed at the outer ring of the disc motor housing 1. To assist in dissipating heat from the outer ring, the outer wall of the disc motor housing 1 is provided with a sliding groove 413. The sliding groove 413 provides a sliding path for the movable heat dissipation fins 414. The movable heat dissipation fins 414 are slidably connected to the inner wall of the sliding groove 413. The movable heat dissipation fins 414 can slide along the sliding groove 413. When the inner ring temperature is high, they can move to the inner ring to enhance heat dissipation. The top of the movable heat dissipation fins 414 is fixedly connected with a sliding rod 415. The sliding rod 415 can drive the movable heat dissipation fins 414 to move along the sliding groove 413. The top of the sliding rod 415 is fixedly connected with a limiting block 416. The limiting block 416 prevents the sliding rod 415 from falling out of the arc groove of the through disc 511. The outer wall of the disc motor housing 1 is provided with a fixing mechanism 5.

[0025] Reference Figures 1-3The fixing mechanism 5 includes a through plate 511, which can rotate to move a slide rod 415. An arc-shaped groove is formed on the inner wall of the through plate 511, providing a sliding track for the slide rod 415. The inner wall of the arc-shaped groove is slidably connected to the outer wall of the slide rod 415. Sliding the slide rod 415 within the arc-shaped groove can change the position of the moving heat dissipation fins 414. A spring 515 is fixedly connected to the bottom of the through plate 511, which can push the through plate 511 upwards. A limiting tooth 512 is fixedly connected to the inner wall of the through plate 511, which can mesh with the teeth of the connecting post 514. A handle 513 is fixedly connected to the outer wall of the through plate 511, facilitating the operator to rotate the through plate 511. A connecting post 514 is fixedly connected to the outer wall of the disc motor housing 1, providing an installation base for the through plate 511. The outer wall is fixedly connected with teeth, which can cooperate with the limiting teeth 512 to fix the through plate 511. The teeth on the outer wall of the limiting teeth 512 and the outer wall of the spring 515 mesh with each other. The meshing of the teeth of the limiting teeth 512 and the connecting column 514 can keep the through plate 511 stable. There are six sets of heat dissipation mechanisms 4. The six sets of heat dissipation mechanisms 4 are arranged in a ring at equal intervals on the outer wall of the disc motor housing 1. The even distribution of the six sets of heat dissipation mechanisms 4 can enhance the heat dissipation effect. The outer wall of the spring 515 is installed on the upper half of the connecting column 514. The installation of the spring 515 on the upper half of the connecting column 514 can ensure that the elastic force is normal. The outer wall of the disc motor housing 1 is rotatably connected to the turntable 516. The turntable 516 provides support for the spring 515. The lower extension end of the spring 515 is fixedly connected to the outer wall of the turntable 516. The connection between the lower extension end of the spring 515 and the turntable 516 can ensure the stability of the extension and contraction of the spring 515.

[0026] Working principle: A heat dissipation mechanism 4 is provided on the back of the disc motor housing 1. An inner ring heat dissipation fin 411 is installed at the center of the outer wall of the disc motor housing 1, while an outer ring heat dissipation fin 412 and a movable heat dissipation fin 414 are installed on the outer ring of the disc motor housing 1. The inner ring of the disc motor, near the central shaft area, has a small space and is occupied by components such as shafts and bearings. The heat transfer path is long and the heat dissipation area is relatively small. It is more difficult for the heat in the inner ring to dissipate, and it is easy to accumulate temperature. Therefore, when the temperature of the inner ring is high, the movable heat dissipation fin 414 is pushed to the inner ring of the disc motor housing 1, thereby enhancing the heat dissipation of the inner ring of the disc motor housing 1. The disc motor housing 1 can also be used with an external fan to enhance the heat dissipation of the disc motor.

[0027] A sliding plate 511 is slidably connected to the top of the slide rod 415. Under normal conditions, the limiting teeth 512 on the inner wall of the sliding plate 511 are engaged and fixed with the teeth on the outer wall of the connecting column 514. When the movable heat dissipation fin 414 is fixed, the sliding plate 511 is pressed down to rotate. The sliding plate 511 drives the slide rod 415 to move along the arc-shaped groove opened in the sliding plate 511, thereby driving the movable heat dissipation fin 414 to gather towards the center of the disc motor housing 1 along the sliding groove 413. After the movable heat dissipation fin 414 is adjusted, the sliding plate 511 is loosened. Under the action of the spring 515, the sliding plate 511 moves up to engage with the teeth on the connecting column 514, keeping the movable heat dissipation fin 414 stable.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
