Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration reduction and noise reduction technology, and in particular to a vibration reduction motor bracket and an air conditioning unit. Background Technology
[0002] The motor of an air conditioning unit generates vibrations during operation, which are transmitted to the chassis and housing through the motor bracket. At certain speeds, this vibration can even resonate with the motor bracket, producing penetrating low-frequency noise. To address this issue, existing vibration-damping motor brackets, such as the air conditioning outdoor unit motor bracket mentioned in Chinese patent document CN209960648U, adjust the stiffness of the motor bracket by fixing it and adding a fixed but adjustable connector at the center of an auxiliary beam, thereby changing its natural frequency and minimizing resonance. However, this method requires an auxiliary beam on the motor bracket, increasing the processing and production costs. Furthermore, the connector length adjustment method is relatively simple, relying solely on a nut and threaded structure for extension and retraction, which cannot achieve a wider range of length adjustments or frequency adjustments, thus limiting further improvements in vibration damping.
[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content
[0004] The present invention provides a vibration damping motor bracket and an air conditioning unit, aiming to solve the problems of high processing and production costs and limited improvement in vibration damping effect of existing vibration damping motor brackets.
[0005] To achieve the above objectives, the solution provided by this utility model is as follows:
[0006] A vibration damping motor bracket includes a base plate, a vertically arranged bracket body connected to the base plate, and a top plate located on the upper part of the bracket body; the bracket body includes two vertically arranged upright plates; a rubber damper is installed on the side of the upright plate away from the motor, and the upright plate is provided with a plurality of mounting holes for installing the rubber damper.
[0007] Optionally, the mounting holes are spaced apart on the vertical plate along the height direction, and the mounting holes on the vertical plate are on the same straight line.
[0008] Optionally, the upright plate is divided into a first region, a second region, and a third region from top to bottom; the rubber damper is installed in the second region; the ratio of the length L1 of the first region, the length L2 of the second region, and the length L3 of the third region is 1:(2.6~3):1.
[0009] Optionally, each of the vertical plates is provided with two rubber dampers.
[0010] Optionally, the rubber dampers on the two vertical plates are arranged symmetrically.
[0011] Optionally, a rubber pad is provided at the bottom of the base plate; the rubber pad is connected to the chassis of the air conditioning unit.
[0012] Optionally, both the base plate and the rubber pad are provided with mounting holes for bolts to pass through.
[0013] This utility model also provides an air conditioning unit, including the aforementioned vibration damping motor bracket.
[0014] Beneficial effects:
[0015] This utility model provides a vibration damping motor bracket. Compared with existing vibration damping motor brackets, the vibration damping motor bracket provided by this utility model does not require the design of complex auxiliary beams. By installing rubber dampers on the upright plate of the motor bracket, the stiffness of the motor bracket can be changed, thereby changing the natural frequency of the motor bracket and minimizing resonance between the motor and the motor bracket.
[0016] Moreover, by setting multiple mounting holes for installing rubber dampers on the upright plate, this utility model allows for the reasonable selection of the number of rubber dampers and adjustment of their installation positions, so that the natural frequency of the motor bracket avoids the excitation frequency of the motor, thereby preventing resonance between the motor and the motor bracket.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0026] Please see Figures 1 to 3 This utility model provides a vibration damping motor 4 bracket, including a base plate 1, a vertically arranged bracket body 2 connected to the base plate 1, and a top plate 3 located on the upper part of the bracket body 2; the bracket body 2 includes two vertically arranged upright plates 21; a rubber damper 5 is installed on the side of the upright plate 21 away from the motor 4, and the upright plate 21 is provided with a plurality of mounting holes 211 for installing the rubber damper 5, so that one or more rubber dampers 5 can be installed on the side of the upright plate 21 away from the motor 4.
[0027] This invention utilizes a rubber damper 5 installed on the side of the upright plate 21 facing away from the motor 4. When the motor 4 vibrates, the rubber damper 5 undergoes elastic deformation under the vibration force. During this process, relative motion and friction occur between the rubber molecular chains, converting the vibrational mechanical energy transmitted from the motor 4 into heat energy, which is then dissipated. This effectively reduces the vibrational energy transmitted to the motor 4 support, thereby suppressing the vibration of the motor 4 support. Furthermore, when the rubber damper 5 is installed on the motor 4 support, it can change the stiffness of the motor 4 support. According to vibration theory, the natural frequency of the motor 4 support is related to its stiffness and mass. Therefore, changes in the stiffness and mass of the motor 4 support will lead to changes in its natural frequency, effectively preventing resonance between the motor 4 and the motor 4 support.
[0028] Compared with the existing vibration damping motor 4 bracket, the vibration damping motor 4 bracket provided by this utility model does not require the design of complex auxiliary beams. By installing rubber dampers 5 on the upright plate 21 of the motor 4 bracket, the stiffness of the motor 4 bracket can be changed, thereby changing the natural frequency of the motor 4 bracket and minimizing resonance between the motor 4 and the motor 4 bracket.
[0029] Furthermore, by providing multiple mounting holes 211 on the upright plate 21 for installing rubber dampers 5, the present invention allows for the reasonable selection of the number of rubber dampers 5 and adjustment of their installation positions, so that the natural frequency of the motor 4 bracket avoids the excitation frequency of the motor 4, thereby preventing resonance between the motor 4 and the motor 4 bracket. The vibration reduction effect is further improved compared to the existing vibration reduction motor 4 bracket.
[0030] In an optional embodiment, the mounting holes 211 are spaced apart along the height direction of the upright plate 21, and the mounting holes 211 on the upright plate 21 are on the same straight line. The spaced distribution of the mounting holes 211 allows the installer to quickly and accurately determine the installation position of the rubber damper 5 based on the specific vibration characteristics of the motor 4 and the actual vibration reduction requirements.
[0031] In an optional embodiment, the upright plate 21 is divided into a first region, a second region, and a third region from top to bottom; the rubber damper 5 is installed in the second region; the ratio of the length L1 of the first region, the length L2 of the second region, and the length L3 of the third region is 1:(2.6~3):1. The second region is located in the middle of the upright plate 21, while the motor 4 is usually installed in the middle of the support body 2. Therefore, the vibration amplitude of the upright plate 21 (support body 2) in the second region is relatively large. Based on this, the present invention installs the rubber damper 5 in the second region, which can adjust the natural frequency of the motor 4 support to the greatest extent, so that it avoids the excitation frequency of the motor 4, thereby effectively avoiding the occurrence of resonance.
[0032] In an optional embodiment, each of the vertical plates 21 is provided with two rubber dampers 5. Providing two rubber dampers 5 on each vertical plate 21 helps maintain the force balance of the vertical plate 21 during vibration, ensuring that the motor 4 bracket maintains a stable structural shape under long-term vibration conditions, extending the service life of the motor 4 bracket, and ensuring the normal operation of the air conditioning unit.
[0033] In an optional embodiment, the rubber dampers 5 on the two upright plates 21 are symmetrically arranged. When the vibration of the motor 4 is transmitted through the support body 2, the symmetrical rubber dampers 5 can buffer and dissipate the vibration in the same way and to the same degree, so that the vibration amplitude of each part of the support is reduced synchronously, effectively avoiding uneven vibration caused by differences in local vibration reduction effect, and comprehensively improving the vibration reduction effect.
[0034] In an optional embodiment, a rubber pad 6 is provided at the bottom of the base plate 1; the rubber pad 6 is located between the base plate 1 and the chassis of the air conditioning unit, and it can absorb the vibration transmitted to the base plate 1, further improving the vibration reduction effect of the motor 4 bracket.
[0035] Optionally, both the base plate 1 and the rubber pad 6 are provided with mounting holes 101 for bolts to pass through, thereby the rubber pad 6 can be fixed between the base plate 1 and the chassis of the air conditioning unit by bolts.
[0036] This utility model also provides an air conditioning unit, including the aforementioned motor 4 bracket. The vibration-damping motor 4 bracket used in this air conditioning unit, by installing rubber dampers 5 on the side of the vertical plate 21 away from the motor 4 and setting multiple mounting holes 211, can flexibly adjust the number and installation position of the rubber dampers 5, effectively changing the stiffness and natural frequency of the motor 4 bracket, avoiding resonance between the motor 4 and the bracket, greatly reducing the transmission of motor 4 vibration to the air conditioning unit chassis and housing shell, reducing the generation of low-frequency noise, and making it quieter during operation compared to traditional air conditioning units, thus improving user comfort.
[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
