Abstract
The utility model discloses a noise-elimination and heat-dissipation structure of a motor, which comprises a supporting device and a sound insulating board, wherein the supporting device is arranged outside a motor shell and connected with the motor shell, a ventilation opening is arranged on the supporting device, a plurality of needle holes are arranged on the sound insulating board, a vibration absorber is arranged in the supporting device, the motor shell is fixedly connected on the vibration absorber, and grooves are formed on the inner wall surface of the supporting device at intervals. The noise-elimination and heat-dissipation structure facilitates the heat dissipation and the noise reduction of the motor.
Description
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of noise elimination radiator structure of motor.
Background technology
The motor that existing household electrical appliance use adopts carbon brush to contact covert formula structure with transducer more, and the brush motor can produce sharp-pointed noise because of friction between brush and the transducer and have a large amount of heats to produce when running up.The noise source of existing motor mainly is the frictional noise between brush and the transducer, considers factors such as heat radiation, safety in utilization, and the household electrical appliance motor mostly is unenclosed construction.The shortcoming of this unenclosed construction motor is: can not intercept the noise of motor, the just transmission that makes the frictional noise that produces between brush and the transducer almost not have to intercept is come out.And because motor is to move under high speed, thereby what produce is sharp-pointed noise, and sharp-pointed noise makes people's mood agitation.Though existing at present people has developed the structure of eliminating the noise for above-mentioned motor,, above-mentioned noise elimination structure makes motor in the relatively poor space of thermal diffusivity, causes the heat radiation of motor to be affected.
Summary of the invention
The purpose of this utility model provides a kind of noise elimination radiator structure of motor, and the utility model helps motor is dispelled the heat, and helps reducing the noise that motor produces.
The technical scheme that realizes the utility model purpose is as follows:
The noise elimination radiator structure of motor, comprise bracing or strutting arrangement and sound insulationg board, bracing or strutting arrangement is arranged on the outside of motor housing and is connected with motor housing, on bracing or strutting arrangement, be provided with ventilating opening, sound insulationg board is provided with some pin holes, be provided with vibration isolator in bracing or strutting arrangement, motor housing is fixedly connected on the vibration isolator, is interval with groove on the described bracing or strutting arrangement internal face.
Be arranged at intervals with some projectioies on the described sound insulationg board.
Pin hole on the described sound insulationg board is positioned on the described projection, and in twos in the groove of adjacent protrusion.
Adopted such scheme, be provided with vibration isolator in bracing or strutting arrangement, motor housing is fixedly connected on the vibration isolator, by subtracting the support device, can reduce the vibration of motor, reduces the sound that is sent because of vibration.Be interval with groove on the described bracing or strutting arrangement internal face,, can increase the surface area of bracing or strutting arrangement, help absorbing the heat that motor sends by groove.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is bracing or strutting arrangement, and 1a is a groove, and 2 is cushion blocking, and 3 is supporting bracket, and 4 is ventilating opening, and 5 is sound insulationg board, and 6 is projection.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, be the noise elimination radiator structure of motor of the present utility model, be interval with groove 1a on bracing or strutting arrangement 1 internal face, after groove is set, can increase the area of bracing or strutting arrangement 1 internal face, help absorbing the heat that motor sends.One cavity is arranged in the bracing or strutting arrangement 1, and this cavity is mainly used to lay motor, and bracing or strutting arrangement 1 is arranged on the outside of motor housing and is connected with motor housing.In bracing or strutting arrangement 1, be provided with vibration isolator, vibration isolator comprises cushion blocking 2 and is positioned at the supporting bracket 3 of this cushion blocking upper surface, be equipped with through hole on cushion blocking 2 and the supporting bracket 3, outer surface at bracing or strutting arrangement 1 is provided with screw, after motor housing places on the supporting bracket, by bolt successively the through hole on bracing or strutting arrangement, cushion blocking 2 and the supporting bracket 3 be connected with motor housing, motor is fixed on the supporting bracket.Be provided with ventilating opening 4 on bracing or strutting arrangement 1, sound insulationg board 5 is provided with some pin holes, and the ventilating opening of flow air by bracing or strutting arrangement 1 flows through the pin hole on the sound insulationg board, can enter into bracing or strutting arrangement 1, can cool off motor.Be arranged at intervals with some protrudingly 6 on the sound insulationg board 5,, also can increase the surface area of sound insulationg board, help absorbing the heat that motor sends by projection 6.Pin hole on the sound insulationg board 5 is positioned on the described projection, and in twos in the groove of adjacent protrusion.
Claims (3)
1. the noise elimination radiator structure of motor, comprise bracing or strutting arrangement and sound insulationg board, bracing or strutting arrangement is arranged on the outside of motor housing and is connected with motor housing, on bracing or strutting arrangement, be provided with ventilating opening, sound insulationg board is provided with some pin holes, it is characterized in that: be provided with vibration isolator in bracing or strutting arrangement, motor housing is fixedly connected on the vibration isolator, is interval with groove on the described bracing or strutting arrangement internal face.
