Description

Technical Field

[0001] This utility model relates to the field of roller shutter door motor technology, specifically to a vibration reduction and noise reduction installation structure for roller shutter door motors. Background Technology

[0002] As a commonly used drive device in modern buildings and industrial facilities, the operational stability and noise control of roller shutter motors have always been key concerns for users. However, in practical applications, roller shutter motors often generate significant vibration and noise during operation. This vibration and noise not only seriously affect the user experience but may also damage the motor itself and its surrounding components, shortening the equipment's lifespan.

[0003] Traditional roller shutter door motor mounting structures often lack effective vibration and noise reduction measures. They typically rely solely on simple bolts or nuts to fix the motor to the mounting plate. While this connection method is simple and quick, it falls short in dealing with the vibration and noise generated by the motor during operation. Especially in modern buildings where the requirements for quiet and comfortable environments are increasingly high, traditional mounting structures can no longer meet the needs of users.

[0004] With advancements in technology and increasing user demands for superior user experience, developing an effective vibration and noise reduction mounting structure for roller shutter door motors has become crucial. This structure needs to effectively absorb vibrations from the motor during operation and isolate the noise it generates, thereby providing users with a quieter and more comfortable operating environment.

[0005] Based on the above background, this utility model proposes a vibration reduction and noise reduction installation structure for a roller shutter door motor. It aims to effectively solve the vibration and noise problems of the roller shutter door motor during operation through reasonable structural design and material selection, improve the user experience of the equipment, and extend the service life of the equipment. Utility Model Content

[0006] In view of this, the technical problem to be solved by the present invention is that the existing roller shutter door motor installation structure is insufficient in terms of shock absorption and noise reduction, which leads to significant vibration and noise during motor operation, affecting the user experience and causing damage to the equipment.

[0007] To address this issue, this utility model provides a vibration damping and noise reduction installation structure for roller shutter door motors. It aims to effectively absorb the vibration energy of the motor during operation and isolate the noise generated by the motor through innovative design and technical means, thereby providing users with a quieter and more comfortable operating environment and improving the service life and reliability of the equipment.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A vibration damping and noise reduction mounting structure for a roller shutter door motor includes a mounting plate, a motor body, a vibration damping device, and a noise reduction component. The mounting plate supports the entire structure, the motor body is mounted on the mounting plate to drive the roller shutter door, the vibration damping device is disposed between the motor body and the mounting plate to absorb the vibration energy during motor operation, and the noise reduction component is wrapped around the outside of the motor body to isolate the noise generated by the motor.

[0010] Furthermore, a gearbox is provided on the mounting plate, and at least three connecting feet are provided at the bottom of the gearbox. The connecting feet are connected to the mounting base on the mounting plate by screws to achieve a stable connection.

[0011] Furthermore, the shock absorption device includes an upper positioning block, a lower positioning block, and a rubber pad. The upper positioning block is disposed at the bottom of the connecting foot, the lower positioning block is disposed at the top of the mounting base, and the rubber pad is disposed between the upper positioning block and the lower positioning block to absorb and disperse vibration energy. The bottom inner ring of the upper positioning block is evenly provided with a plurality of upper slots, and the top inner ring of the lower positioning block is provided with lower slots that correspond one-to-one with the upper slots. The rubber pad is disposed between the upper slots and the lower slots.

[0012] Furthermore, the shock absorption device also includes an arc-shaped plate and a spring. The arc-shaped plate is disposed between the bottom outer ring of the upper positioning block and the top outer ring of the lower positioning block. One end of the spring is fixedly connected to the bottom of the upper positioning block, and the other end is fixedly connected to the top of the lower positioning block.

[0013] Furthermore, the noise reduction component includes a noise reduction shell, an extension piece, and sound insulation cotton. The noise reduction shell wraps around the outside of the motor body, the extension piece is disposed on the inner wall of the noise reduction shell and extends into the noise reduction hole of the motor body, and the sound insulation cotton fills the space between the inner wall of the noise reduction shell and the outer wall of the motor body.

[0014] Furthermore, the noise-reducing shell is made of ABS plastic with a thickness of 2-3mm. Several V-shaped grooves are formed on both sides of the extension plate. The groove walls of the V-shaped grooves make multi-angle contact with the surface of the sound-insulating cotton. The sound-insulating cotton is bonded to the outer wall of the motor body using polyurethane adhesive.

[0015] Furthermore, the height of the sound-insulating cotton is the same as that of the noise-reducing shell.

[0016] Furthermore, the sound insulation cotton has a thickness of 15-20mm, and when the sound insulation cotton is embedded in the V-shaped groove, the groove wall of the V-shaped groove can undergo slight elastic deformation to enhance the tightness and stability of the connection.

[0017] As can be seen from the above technical solution, the advantages of this utility model are:

[0018] 1. Significantly reduces vibration and noise:

[0020] The vibration damping device adopts a multi-layered vibration damping system, including components such as rubber pads, arc plates, and springs. These components work together to absorb and disperse vibration energy in all directions, ensuring the smooth operation of the motor.

[0021] The noise reduction components, through structures such as noise reduction shells, extension plates, and sound insulation cotton, form a closed soundproof space, effectively isolating the noise generated during motor operation and providing users with a quieter environment.

[0022] 2. Improve equipment lifespan and reliability:

[0023] By reducing vibration and noise during motor operation, the installation structure of this invention effectively reduces damage to the motor itself and its surrounding components, thereby improving the service life and reliability of the equipment.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0044] refer to Figures 1 to 7 ,like Figure 1 As shown, this embodiment provides a vibration damping and noise reduction installation structure for a roller shutter door motor, mainly composed of a mounting plate 2, a motor body 1, a vibration damping device 3, and noise reduction components. The mounting plate 2 serves as the supporting foundation for the entire structure and is made of high-quality Q235 carbon structural steel plate with a thickness of 8-12mm, possessing sufficient strength and rigidity. A reduction gearbox 4 is mounted on it, with three connecting feet 41 at the bottom. The connecting feet 41 are cylindrical, with a diameter of 15-20mm and a height of 20-25mm. A raised mounting seat 21, 10-15mm high, is located on the inner bottom wall of the mounting plate 2, and the mounting seats 21 correspond one-to-one with the connecting feet 41. Screws 7 pass through through holes (5-6mm in diameter) in the connecting feet 41 and are tightened onto the mounting seats 21 to achieve a stable connection and ensure durability. The motor body 1 is mounted on the top of the reduction gearbox 4, providing power for the operation of the roller shutter door.

[0045] A noise reduction component is installed on the exterior of the motor body 1. This component is centered around a noise reduction shell 5, which is made of 2-3mm thick ABS plastic, providing good sound insulation and corrosion resistance. The bottom of the noise reduction shell 5 is tightly pressed against the top of the gearbox 4. By applying a layer of sealant with a thickness of 0.5-1mm to the contact surface, a tight connection is ensured, forming a closed soundproof space that effectively isolates the noise generated by the motor body 1 during operation.

[0046] like Figure 6 As shown, the inner wall of the noise-reducing housing 5 is uniformly provided with several extension pieces 51. The extension pieces 51 are 10-15mm long, 5-8mm wide, and 1-2mm thick. Several noise-reducing holes 11 are opened at positions corresponding to the outer wall of the motor body 1. The ends of the extension pieces 51 can extend into these noise-reducing holes 11, penetrating deep into the housing of the motor body 1, thereby effectively controlling the noise generated during motor operation. Furthermore, as... Figure 7 As shown, several V-shaped grooves 511 are also provided on both sides of the extension plate 51. The included angle of the V-shaped grooves 511 is 60°-90° and the depth is 2-3mm. The design of these V-shaped grooves 511 not only increases the strength of the extension plate 51, but may also help to further disperse and absorb noise, thereby improving the noise reduction effect.

[0047] like Figure 5As shown, to further enhance the sound insulation effect, the noise reduction component also includes sound insulation cotton 6. Sound insulation cotton 6 is filled between the inner wall of the noise reduction shell 5 and the outer wall of the motor body 1. Sound insulation cotton 6 not only has excellent sound insulation performance but also effectively absorbs and disperses noise energy. Specifically, sound insulation cotton 6 is bonded to the outer wall of the motor body 1 using polyurethane adhesive. The adhesive application thickness is 0.3-0.5mm, ensuring a tight fit between the sound insulation cotton 6 and the motor body 1. Simultaneously, the height of sound insulation cotton 6 is the same as that of the noise reduction shell 5, both being 30-40mm, ensuring that the overall sound insulation effect of the noise reduction component reaches its optimal level.

[0048] The V-groove 511 forms multi-angle contact with the surface of the sound insulation cotton 6, significantly increasing the contact area compared to a planar structure. This geometry generates greater friction during pressing, making the connection between the sound insulation cotton 6 and the V-groove 511 more stable and effectively preventing loosening.

[0049] The V-groove 511's opening design allows the edge of the sound insulation cotton 6 to be embedded in the groove, forming a mechanical fit. When the sound insulation cotton 6 is subjected to external force, the fit structure disperses stress through the support of the groove wall, avoiding tearing or detachment caused by localized stress concentration, thereby improving the reliability of the connection.

[0050] When the sound-insulating cotton 6 is embedded in the V-groove 511, the groove wall undergoes slight elastic deformation. This deformation not only enhances the tightness of the fit but also reduces noise transmission by absorbing vibration energy. At the same time, the elastic restoring force compensates for the relaxation of the material after long-term use, maintaining connection stability.

[0051] Regarding the thickness and material of the sound insulation cotton 6, this embodiment selects a sound insulation cotton material with excellent sound insulation performance and high temperature resistance. The thickness of the sound insulation cotton 6 has been precisely calculated and designed to be 15-20mm to ensure that sufficient sound insulation effect is maintained without adding excessive weight and volume.

[0052] A shock-absorbing device 3 is installed at the position of the mounting base 21 corresponding to the connecting foot 41. The main function of the shock-absorbing device 3 is to absorb the vibration generated by the motor 1 during operation, thereby effectively avoiding the noise generated by the roller shutter motor due to vibration during use. The shock-absorbing device 3 includes an upper positioning block 31, a lower positioning block 32, and a rubber pad 33. The components work together to provide an all-round shock absorption effect.

[0053] like Figure 2 As shown, the upper positioning block 31 is located at the bottom of the connecting foot 41, and the lower positioning block 32 is located at the top of the mounting base 21. The tops of the upper positioning block 31 and the lower positioning block 32 are both circular with a diameter of 25-30mm. A through hole 36 with a diameter of 6-7mm is provided at the corresponding through hole position on the connecting foot 41.

[0054] When installing the shock absorber 3, screws 7 are passed through the through holes and through holes 36 on the connecting foot 41 and tightened onto the mounting base 21. The shock absorber 3 is pressed tightly between the connecting foot 41 and the mounting base 21 to ensure that the shock absorber 3 is securely installed.

[0055] The upper positioning block 31 has several upper slots 312 evenly distributed on its bottom inner ring, which correspond one-to-one with several lower slots 322 on the top inner ring of the lower positioning block 32. Several rubber pads 33 are disposed between the upper slots 312 and the lower slots 322, and the rubber pads 33 are arranged around the through hole 36. As the first shock absorption structure, the rubber pads 33 are made of natural rubber with a Shore hardness of 50-60A. The soft and elastic material can effectively absorb and disperse vibration energy.

[0056] In one embodiment, such as Figure 3 As shown, the bottom outer ring of the upper positioning block 31 is evenly provided with several upper grooves 311, which correspond one-to-one with several lower grooves 321 provided on the top outer ring of the lower positioning block 32.

[0057] Furthermore, such as Figure 4 As shown, the damping device 3 also includes several arc-shaped plates 34, which are disposed between the upper groove 311 and the lower groove 321, and surround the through hole 36. The arc-shaped plates 34 have a V-shaped vertical cross-section and are composed of two integrally formed side plates 342 and an arc-shaped part 341 connected in the middle. The side plates 342 have a thickness of 1-1.5 mm, and the arc-shaped part 341 has a radius of 8-12 mm. This design not only enhances the structural stability of the damping device 3, but also allows the arc-shaped plates 34 to deform to a certain extent when vibration occurs, further dissipating vibration energy.

[0058] To further enhance the effect of the shock absorption device 3, this embodiment also includes a number of springs 35 evenly arranged. One end of each spring 35 is fixedly connected to the bottom of the upper positioning block 31, and the other end is fixedly connected to the top of the lower positioning block 32, forming a central shock absorption structure. The springs 35 are also arranged around the through hole 36 and are positioned between the rubber pad 33 and the arc plate 34. The springs 35 are made of 65Mn spring steel with a diameter of 3-4mm and a wire diameter of 0.8-1mm. Their elasticity and restoring force enable the shock absorption device 3 to maintain a good working condition even when facing strong vibrations.

[0059] The curved plate 34, spring 35 and rubber pad 33 work together to form a multi-layered damping system, which effectively improves the damping performance of the damping device 3.

[0060] In one embodiment, there are three connecting feet 41, and correspondingly, three shock-absorbing devices 3 are also provided.

[0061] Furthermore, the top of the motor body 1 and the gearbox 4 are connected by a precise fastening structure or by bolts and nuts, ensuring the stability and reliability of the connection. This connection method not only facilitates installation and disassembly but also effectively transmits power and reduces energy loss.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model. 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.
