Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a vibration reduction structure and electrical equipment. Background Art

[0002] The equipment inside existing electrical equipment is generally fixed to the inside of the housing of the electrical equipment through a bracket. Due to space limitations, the equipment is often installed in the air on the housing. Since the center of gravity of the equipment is far away from the installation point, the equipment vibrates greatly during operation. Taking the air conditioner as an example, the installation structure of the motor is generally to fasten the end cover foot to the air conditioner installation base plate, and vibration-damping rubber pads can be used between the foot and the base plate for vibration reduction design. This design can reduce the fixed-frequency vibration between the foot and the base plate when the motor is running, but it cannot solve its own structural defects. For example, when the motor foot is installed, the vibration accumulated at the foot by the weight of the motor will be large. Vibration not only affects the reliable operation of electrical equipment, but also causes a lot of noise. Summary of the invention

[0030] Therefore, the present invention provides a Figure 2 The vibration reduction structure shown includes a bracket 1 and a vibration reduction pad 2. The bracket 1 includes a bracket chassis 11. A vibration reduction bracket extends axially from the bracket chassis 11. The bracket chassis 11 and the vibration reduction bracket together constitute a double vibration reduction structure of the device to be supported.

[0031] A vibration-damping bracket extends from the bracket chassis 11 along its axial direction. The bracket chassis 11 and the vibration-damping bracket together constitute a double vibration-damping structure of the device to be supported, which effectively improves the vibration-damping effect of the motor 4 and reduces noise.

[0036] As an optional implementation, the short side of the L-shaped support plate 12 is the mounting portion 122 , and the long side is the extending portion 121 .

[0037] The short side of the L-shaped support plate 12 is the mounting portion 122 , and the long side is the extension portion 121 . The structure has high reliability and reasonable force.

[0038] As an optional implementation, a plurality of support plates 12 are evenly distributed on the support chassis 11 .

[0039] A plurality of support plates 12 are evenly distributed on the support chassis 11 , so that the force is evenly applied everywhere, and the stability and reliability are high.

[0040] As an optional embodiment, the support chassis 11 is annular, and the vibration-damping bracket is formed by axially extending the inner ring of the annular ring.

[0041] The support chassis 11 is annular, and the vibration-damping bracket extends axially from the inner ring of the annular structure, which has a compact structure and makes reasonable use of space.

[0042] As an optional implementation, a reinforcing rib 5 is provided at the connection between the vibration-damping bracket and the support chassis 11 .

[0043] The reinforcing rib 5 increases the strength of the vibration-damping bracket, prolongs the service life of the vibration-damping bracket, and improves reliability.

[0044] As an optional implementation, the vibration damping pad 2 includes a first vibration damping pad 21 and a second vibration damping pad 22 , the first vibration damping pad 21 is cooperatively connected to the support chassis 11 , and the second vibration damping pad 22 is cooperatively connected to the vibration damping bracket.

[0045] The first vibration damping pad 21 and the second vibration damping pad 22 are both rubber pads. Figure 5 The structure of the first vibration damping pad 21 is given. Figure 6 and Figure 7 The structure of the second vibration damping pad 22 is shown. However, its shape and structure are not limited to those shown in the figure. In addition, the number of the support plates 12 is not limited to four, and the support plates 12 can also be designed in a circular shape.

[0046] As an optional implementation, Figure 3 As shown, a plurality of mounting grooves 111 are formed on the outer edge of the bracket chassis 11 , and a plurality of rubber pads serving as the first vibration-damping pads 21 are correspondingly mounted in the mounting grooves 111 .

[0047] A recessed structure is provided at the edge of the mounting groove 111 to facilitate the connection with the first vibration-damping pad 21 .

[0048] As an optional implementation, when the support chassis 11 is fixed to the mounting surface, the vibration-damping bracket is close to the cross section where the center of gravity of the device to be supported is located.

[0049] The vibration-damping bracket is close to the cross section where the center of gravity of the equipment to be supported is located, which can stably support the equipment and minimize vibration and noise.

[0050] The present invention provides an air conditioner, comprising any of the above double vibration reduction structures.

[0051] like Figure 4 As shown, the motor 4 of the indoor unit of the air conditioner is fixed on the load base plate 3 of the air conditioner through a vibration reduction structure.

[0052] The first vibration-damping pad 21 is mounted in the mounting groove 111 of the bracket chassis 11, and is locked together with the load base plate 3 by bolts and nuts as fasteners. The second vibration-damping pad 22 is mounted on the mounting portion 122 of the support plate 12, and is locked and fixed to the bracket 1 by screws and nuts as fasteners, so as to improve the vibration-damping effect of the motor 4 and reduce the noise of the motor 4.

[0053] The motor 4 load base plate 3 is provided with bolts corresponding to the number of the motor 4 mounting feet. The first vibration damping pad 21 is assembled in the rubber pad mounting groove 111 of the chassis of the bracket 1. The second vibration damping pad 22 is assembled together with the bracket 1 on the load base plate 3 bolts and fastened together with the load base plate 3 bolts by nuts.

[0054] The mounting edge of the motor 4 is provided with holes having the same number as the mounting portion 122 , and the U-shaped second vibration damping pad 22 is assembled on the mounting portion 122 .

The extension portion 121 is perpendicular to the support chassis 11 and the mounting portion 122, and a reinforcing rib 5 is used at the bottom connection to increase the strength of the support 1.

[0056] The height L1 of the bracket 1 after the first vibration-damping pad 21 and the second vibration-damping pad 22 are assembled is higher than the height L2 of the rear end cover of the motor 4 to prevent interference or noise caused by contact with the load base plate 3 .

[0057] The mounting position of the first vibration damping pad 21 of the chassis of the bracket 1 is bent through an arc transition to increase the structural strength of the bracket chassis 11. The surface of the chassis of the bracket 1 that contacts the rubber pad is slightly larger than the contact surface of the first vibration damping pad 21. The mounting groove 111 on the bracket chassis 11 is equivalent to the diameter of the slot of the first vibration damping pad 21, and the thickness of the bracket chassis 11 is equivalent to the width of the slot of the first vibration damping pad 21 to prevent loosening. The slot width of the U-shaped second vibration damping pad 22 is the same as the thickness of the support bracket, and its contact surface matches the shape and size of the mounting portion 122.
