Description

Technical Field

[0001] The utility model specifically relates to the technical field of shock-absorbing and noise-reducing motors, and specifically is a shock-absorbing and noise-reducing motor for a fan. Background Technique

[0002] A motor (English: Electric machinery, commonly known as "motor") is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is represented by the letter M in the circuit (D in the old standard). Its main function is to generate a driving torque and serve as a power source for electrical appliances or various machines; while the motor box is a box for fixing the motor.

[0003] Currently, the driving method adopted by traditional fans is that a water motor drives the fan blades to rotate. Through the rotation of the fan blades, the flow of air is realized, the exchange between hot air and cold air is realized, and the cooling effect is achieved. However, during the use of traditional fans, the rotating shaft of the motor rotates at a high speed, which will cause the fan blades to vibrate, resulting in the deviation of the fan blades, and thus the fan blades will be damaged. Currently, traditional motors are directly connected to equipment during installation. In this way, when vibration occurs, the overall motor will vibrate significantly, which not only damages the fan blades but also causes great damage to the motor itself.

[0004] After retrieval, Chinese Patent Publication No. CN201921946836.5 discloses a noise-reducing and heat-dissipating device for a motor; it includes a base, a first shock-absorbing connecting column, a partition board, a connecting column, a first through hole, sound insulation cotton, a rotating shaft, an end cover, a rotor, a stator, a support plate, a sound insulation layer, a housing, a rear cover, a fan. The top of the base is fixedly connected with first shock-absorbing connecting columns at equal distances from left to right in sequence. The top of the first shock-absorbing connecting column is fixedly connected with a housing. There are multiple second through holes on the upper end of the end cover. Two partition boards are fixedly connected to the left and right sides of the support plate at equal distances. A rotating shaft is rotatably connected between the partition boards. A rotor is fixedly connected to the center position of the rotating shaft. A fan is sleeved on one end of the left side of the rotating shaft. The center position of the bottom of the base is fixedly connected with a bottom plate. Fixing blocks are fixedly connected to the left and right sides of the top of the bottom plate. Upper connecting blocks are fixedly connected to the front, rear, left, and right sides of the bottom of the base;

[0005] When the structure in the above patent reduces noise, the generated noise inside is isolated from the outside through the sound insulation cotton and the sound insulation layer. However, when the motor is working, the heat generated inside cannot be effectively transmitted. In this way, during long-term operation, the overall temperature of the motor will be relatively high, resulting in the overload of the motor, and even seriously causing the motor to burn out;

[0006] In view of the above situation, we provide a shock-absorbing and noise-reducing motor for a fan. In this device, a plurality of shock-absorbing sponge blocks are arranged inside the housing through a fixing frame. When the rotating shaft vibrates, the fixing frame and the shock-absorbing sponge blocks effectively absorb the vibration effect, preventing the vibration from being transmitted to the housing. The fixing frames are arranged at intervals, so that during long-term use, the temperature generated inside the housing is transmitted to the housing through the gap between two adjacent fixing frames, and the heat dissipation effect is achieved through the heat dissipation fins integrally arranged on the housing.
