Abstract
The invention discloses a buzzer and instrument rear cover installation structure which comprises an instrument rear cover and a buzzer. The buzzer is located on the inner side of the instrument rear cover. A sound hole area right opposite to the buzzer is formed in the instrument rear cover. An inner circular ring and an outer circular ring which are integrally formed with the rear cover are arranged outside the sound hole area. The inner circular ring and the outer circular ring are coaxially arranged. A sponge gasket is installed between the inner circular ring and the outer circular ring, is higher than the inner circular ring and the outer circular ring and elastically supports the buzzer. Notches are distributed in the circumference of the inner circular ring and the circumference of the outer circular ring. The number of the notches in the inner circular ring is equal to that of the notches in the outer circular ring, and the notches in the inner circular ring correspond to the notches in the outer circular ring in position. The buzzer is elastically compressed through elasticity of the sponge gasket, the buzzer is protected against damage, and meanwhile the problem that other abnormal sounds are caused due to the fact that the vibration generated during buzzing of the buzzer drives other mechanical pieces to vibrate is solved; rigidity contact between the buzzer and the instrument rear cover is avoided, and the service life of the buzzer is prolonged.
Description
Technical field
The present invention relates to technical field of automobile parts, be specifically related to the mounting structure of a kind of hummer and instrument bonnet.
Background technology
Instrument bonnet is equipped with hummer, and hummer is fixed by welding on instrument pcb board.Hummer usually produces loosening because welding bad, clashes into instrument bonnet, pcb board and produces abnormal sound; Due to hummer and instrument bonnet rigid contact, probably damage hummer: meanwhile, vibrations during buzzer call, other mechanical parts also can be driven to shake and send Abnormal Sound.
Summary of the invention
The present invention aims to provide the mounting structure of a kind of hummer and instrument bonnet, solves the abnormal sound problem loosening and produce, and extends the serviceable life of hummer.
For this reason, the technical solution adopted in the present invention is: the mounting structure of a kind of hummer and instrument bonnet, comprise instrument bonnet and hummer, described hummer is positioned at the inner side of instrument bonnet, instrument bonnet has just to the sound hole district of hummer, and described sound hole district is outside equipped with integrated interior annulus, outer toroid with bonnet, described inside and outside annulus is coaxially arranged, and between inside and outside annulus, sponge washer being housed, described sponge washer is higher than inside and outside annulus, and carries out resiliency supported to hummer; Inside and outside annulus is provided with circumferentially uniform short slot, and short slot quantity on inside and outside annulus is equal, position is corresponding.
Preferred as such scheme, described inside and outside annulus is contour, uniform thickness, is convenient to one-body molded.
Beneficial effect of the present invention: by setting up inside and outside annulus for fixing sponge washer, hummer is welded on pcb board, and utilize the elasticity of sponge washer self to carry out elastic compression to hummer, protection hummer is injury-free, and vibrations when simultaneously solving buzzer call drive other mechanical parts shake and cause other abnormal sound; Avoid hummer and instrument bonnet rigid contact, extend the serviceable life of hummer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the state after Fig. 1 takes off hummer.
Fig. 3 is the state after Fig. 2 takes off sponge washer.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
Shown in composition graphs 1-Fig. 3, form primarily of instrument bonnet 1, hummer 7 and sponge washer 4.
Hummer 7 is positioned at the inner side of instrument bonnet 1, and instrument bonnet 1 has just to the sound hole district 6 of hummer 7, sound hole district 6 is made up of the sound hole of some circles, identical with existing structure.
Be outside equipped with integrated interior annulus 2, outer toroid 3 with bonnet 1 in sound hole district 6, inside and outside annulus 2,3 is coaxially arranged, and between inside and outside annulus 2,3, sponge washer 4 is housed, interior annulus 2, outer toroid 3 are for fixing sponge washer 4.Sponge washer 4 is higher than inside and outside annulus 2,3, and carries out resiliency supported to hummer 7.Hummer 7 is welded on instrument pcb board, and the elasticity of recycling sponge washer 4 self carries out elastic compression to hummer 7.
For avoiding the sound of hummer 7 to be enclosed in inside and outside annulus 2,3, outer toroid 2,3 is provided with circumferentially uniform short slot 5, and the quantity of short slot 5 is generally 3-4, but is not limited to 3-4, thus the sound allowing hummer 7 send is dispersed out everywhere; Short slot quantity on inside and outside annulus 2,3 is equal, position is corresponding, more smooth and easy when guaranteeing transmission sound.Preferably, contour, the uniform thickness of inside and outside annulus 2,3.
Claims (2)
1. the mounting structure of a hummer and instrument bonnet, comprise instrument bonnet (1) and hummer (7), it is characterized in that: described hummer (7) is positioned at the inner side of instrument bonnet (1), instrument bonnet (1) have just to the sound hole district (6) of hummer (7), described sound hole district (6) is outside equipped with the integrated interior annulus (2) with bonnet (1), outer toroid (3), in described, outer toroid (2, 3) coaxially arrange, and interior, outer toroid (2, 3) sponge washer (4) is housed between, in described sponge washer (4) ratio, outer toroid (2, 3) high, and resiliency supported is carried out to hummer (7), inside and outside annulus (2,3) is provided with circumferentially uniform short slot (5), and short slot quantity on inside and outside annulus (2,3) is equal, position is corresponding.
2. the mounting structure of hummer according to claim 1 and instrument bonnet, is characterized in that: described inside and outside annulus (2,3) contour, uniform thickness.
