Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a low-noise drive motor for garage doors. Background Technology

[0002] Garage doors, a common feature in modern buildings, generally rely on electrically driven motors for their automated opening and closing. Traditional garage door motor designs prioritize drive reliability and structural simplicity; therefore, the motor and its transmission mechanism are typically encased in a basic protective shell without any special measures taken to mitigate operating noise.

[0003] However, as people's demands for quality of life continue to rise, the mechanical and electromagnetic noise generated by these traditional motors during operation has gradually become a problem that cannot be ignored. This noise not only affects the quietness of the surrounding environment of the garage, but when the garage is directly connected to the living space, the transmission of noise will also interfere with the daily life of users, significantly reducing the comfort of living.

[0004] To address the noise problem, some improvements have been attempted in the industry. The core idea is to block the propagation of sound by adding a closed structure, such as adding a thicker and more airtight soundproof cover to the motor. Although this method can block the noise from spreading outward to some extent, it directly causes a new and more difficult problem: heat dissipation. When the motor works for a long time, it will generate a lot of heat. If this heat is completely sealed in the soundproof cover and cannot be dissipated in time, it will cause the temperature of the motor body to continue to rise.

[0005] Sustained high-temperature operation is extremely detrimental to motors. It not only accelerates the aging of internal coil insulation layers, lubricating grease, and other materials, reducing motor operating efficiency and output torque, but in more serious cases, it may cause coil burnout, thereby severely shortening the motor's service life and even posing potential safety hazards. To address these issues, a low-noise drive motor for garage doors is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a low-noise drive motor for garage doors, aiming to improve the problems of high noise during operation and difficulty in heat dissipation after sealing in existing garage door motors.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A low-noise drive motor for garage doors includes: a motor body, a front cover and a rear cover fixed at both ends of the motor body; and a noise reduction component and a heat dissipation component.

[0009] The noise reduction assembly includes an upper cover and a lower cover that interlock, with mounting grooves on the inner sides of the upper and lower covers, and the upper and lower covers are fixedly connected by screws. The heat dissipation assembly includes an air inlet on the lower cover, an air outlet on the noise reduction assembly, and a silent fan inside the noise reduction assembly.

[0010] Furthermore, the noise reduction component is detachably covered on the outside of the motor body by engaging with the mounting rings on the outside of the front and rear covers via its mounting slot; the noise reduction fan of the heat dissipation component is located on the airflow channel between the air inlet and the air outlet, thus forming a complete noise reduction and heat dissipation structure.

[0011] Preferably, sound-absorbing cotton is fixed on the inner walls of the upper and lower covers.

[0012] Preferably, a fixing block is provided on one side of the upper cover, and two support blocks are provided on the corresponding side of the lower cover. The fixing block is rotatably connected between the two support blocks by a round rod to form a pivot structure.

[0013] Preferably, a knob for driving its rotation is connected to the screw.

[0014] Preferably, a dustproof net is provided at the air inlet, and a guide plate is provided inside the air inlet.

[0015] Preferably, a dustproof net is provided at the exhaust vent.

[0016] Preferably, heat dissipation fins are provided on the outer side wall of the motor body.

[0017] Preferably, the motor shaft of the motor body is provided with a shaft groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a detachable noise-reducing component is used to completely enclose the motor body. The housing of this component itself serves as sound insulation, while the sound-absorbing cotton fixed on its inner wall effectively absorbs the noise generated when the motor is working. Under this dual effect, the operating noise of the transmission motor is greatly reduced, and the user's comfort is improved.

[0020] 2. In this utility model, to address the heat dissipation problem caused by the enclosed motor in the silent assembly, this solution incorporates an independent heat dissipation component. Through the coordination of a silent fan, air inlet, and exhaust outlet, forced convection airflow is created, effectively dissipating the heat emitted by the motor's cooling fins. This solves the heat dissipation problem in a closed environment, ensuring stable long-term motor operation and extending its service life.

[0021] 3. In this utility model, the upper and lower covers of the noise-reducing component are connected by rotation on one side and locked by a knob screw on the other side. This design makes the installation and disassembly of the noise-reducing component very convenient and quick, and it can be opened for internal inspection or maintenance without complicated tools, making it highly operable.

[0022] 4. In this utility model, dust filters are installed at both the air inlet and exhaust outlet, effectively preventing dust and debris from entering the interior of the silent component, protecting the cleanliness of internal components such as the motor body and silent fan, and improving the durability and operational reliability of the entire device. Simultaneously, the air inlet's guide vane design optimizes airflow, further enhancing heat dissipation. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-6 This utility model provides a low-noise drive motor for garage doors, aiming to solve the technical problems of high noise and difficulty in heat dissipation when garage door motors are in operation and when the doors are closed.

[0033] The garage door uses a low-noise drive motor, which includes a motor body 1, a front cover 2 and a rear cover 3 fixedly connected to both ends of the motor body 1. The motor shaft 4 of the motor body 1 passes through the front cover 2 and the rear cover 3. The motor shaft 4 is rotatably connected by bearings set inside the front cover 2 and the rear cover 3. The motor shaft 4 has a shaft groove 5. Multiple heat dissipation fins 8 are provided on the outer side wall of the motor body 1.

[0034] The noise reduction component 6 is a hollow shell that is detachably covered on the outside of the motor body 1. The noise reduction component 6 includes an upper cover 601 and a lower cover 602, which are fastened together. Sound-absorbing cotton 610 is fixedly connected to the inner sidewalls of the upper cover 601 and the lower cover 602. The inner side of the upper cover 601 and the lower cover 602 are also provided with mounting grooves 609, which are engaged with mounting rings 608 fixed on the outside of the front cover 2 and the rear cover 3.

[0035] To enable the opening, closing, and locking of the upper cover 601 and the lower cover 602, a fixing block 603 is fixedly provided on one side of the upper cover 601, and two support blocks 604 are fixedly provided on the corresponding side of the lower cover 602. The two ends of a round rod 605 are respectively fixedly connected to the two support blocks 604. The fixing block 603 and the round rod 605 are rotatably connected. An upper fixing strip 606 is fixedly provided on the other side of the upper cover 601, and a lower fixing strip 607 is fixedly provided on the corresponding side of the lower cover 602. A screw 611 is rotatably connected to the upper fixing strip 606. The end of the screw 611 is threadedly connected to the threaded hole of the lower fixing strip 607. A knob 612 is fixedly connected to the top of the screw 611.

[0036] The heat dissipation component 7 includes a silent fan 706 located inside the silent component 6. The silent fan 706 is fixed on the mounting bracket 705, which is fixedly connected to the inner wall of the silent component 6. An air inlet 701 is provided on the lower cover 602, and an exhaust outlet 702 is also provided on the silent component 6. The silent fan 706 is located in the airflow channel between the air inlet 701 and the exhaust outlet 702. A dustproof net 703 is fixedly provided at the air inlet 701, and a guide plate 704 is fixedly provided inside the air inlet 701. A dustproof net 703 is also fixedly provided at the exhaust outlet 702.

[0037] To achieve excellent noise reduction, sound-absorbing cotton 610 is fixedly connected to the inner walls of the upper cover 601 and the lower cover 602. The large area coverage of the sound-absorbing cotton 610 can fully absorb the noise generated by the motor body 1 when it is working.

[0038] To facilitate the opening and maintenance of the silent component 6, the fixing block 603 on one side of the upper cover 601 and the two support blocks 604 on one side of the lower cover 602 are rotatably connected by a round rod 605, forming a pivot structure. On the other side of the upper cover 601 and the lower cover 602, the screw 611 is driven by the knob 612 to screw in or out between the upper fixing strip 606 and the lower fixing strip 607, so as to realize the quick locking and unlocking of the silent component 6.

[0039] To ensure the cleanliness of the interior of the silent component 6, dust filters 703 are fixedly installed at both the air inlet 701 and the air outlet 702. The dust filter 703 in the air inlet 701 is used to filter the incoming air, and the dust filter 703 at the air outlet 702 is used to prevent external dust from entering when the silent fan 706 is not working. A guide plate 704 is also fixedly installed inside the air inlet 701 to regulate the airflow direction and increase the wind speed.

[0040] To improve the performance of the basic components, multiple heat dissipation fins 8 are integrally formed on the outer side wall of the motor body 1 to increase the heat dissipation surface area and improve the heat exchange efficiency with the air. A shaft groove 5 is provided on the motor shaft 4 for key connection with external drive components to ensure reliable torque transmission.

[0041] Working principle: When installing and using this low-noise drive motor, firstly, use screws to fix the front cover 2 and the rear cover 3 to both ends of the motor body 1, so that the motor shaft 4 inside the motor body 1 can rotate on the bearings inside the front cover 2 and the rear cover 3. When installing the motor body 1, fix the components to be driven through the shaft groove 5 on the motor shaft 4. Then, install the upper cover 601 and the lower cover 602 on the outside of the motor body 1. Secure the mounting groove 609 on the inside of the upper cover 601 and the lower cover 602 onto the mounting ring 608 on the side of the front cover 2 and the rear cover 3 near the motor body 1. Then close the upper cover 601 and the lower cover 602. Rotate the knob 612 so that the screw 611 on the upper fixing strip 606 is threaded into the threaded hole on the lower fixing strip 607, thus firmly fixing the upper cover 601 and the lower cover 602 to the outside of the motor body 1.

[0042] During operation, the noise generated by the motor body 1 is partially blocked by the housing of the silent component 6, and the other part is absorbed by the sound-absorbing cotton 610 fixed on the inner wall of the upper cover 601 and the lower cover 602, thereby significantly reducing the sound transmitted to the outside when the motor is working.

[0043] Meanwhile, the motor body 1 generates heat after it starts working. The heat is dissipated from the multiple heat dissipation fins 8 on the outside of the motor body 1. When the silent component 6 is installed, the heat will accumulate inside the silent component 6. At this time, the heat dissipation component 7 needs to be activated. The silent fan 706 on the mounting bracket 705 starts working and exhausts the heat dissipated by the motor body 1 inside the silent component 6 through the airflow from the exhaust port 702. After the hot air is exhausted, the outside air will enter the silent component 6 through the air inlet 701 opened in the middle of the lower cover 602. When the air enters, it first passes through the dust filter 703 for filtration, and then passes through the guide plate 704 to change the flow direction and increase the airflow to cool the motor body 1.

[0044] When it is necessary to open for maintenance, turn the knob 612 in the opposite direction to rotate the screw 611 and remove the screw 611 from the lower fixing bar 607. This will release the upper cover 601 and the lower cover 602 from the locked state. Then, let the upper cover 601 rotate on the round rod 605 between the two support blocks 604 on the other side of the lower cover 602 via the fixing block 603 on the other side. This will open the upper cover 601 and the lower cover 602 so that the motor body 1 can be maintained.

[0045] 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.
