Description
Technical field
The present invention relates to technical field of automobile parts, and in particular to a kind of instrument lamp-box frame combines knot with the installation of bonnet
Structure.
Background technology
Liquid crystal display and PCB are installed in lamp-box frame, the upper surface of bonnet and the lower surface of lamp-box frame are fitted in
Together, tightened together in conjunction with screw.The installation of bonnet and lamp-box frame lacks position limiting structure, installs inconvenient；Bonnet is thin
Plate, easily deforms after installation；The installation seal of bonnet and lamp-box frame is poor, and dust and electrostatic are easily accessible in lamp-box frame,
Disturb the normal work of liquid crystal display and PCB.
Instrument bonnet is built with buzzer, and buzzer is fixed by welding on instrument pcb board.Buzzer is usually because of welding
It is bad and produce loosening, with instrument bonnet, pcb board hit and produce abnormal sound；Due to buzzer and instrument bonnet rigid contact, very
Buzzer may be damaged：Meanwhile, vibrations during buzzer call can also drive the vibrations of other mechanical parts to send Abnormal Sound.
The content of the invention
Present invention seek to address that instrument bonnet installs inconvenience with lamp-box frame, seals poor, it is impossible to prevent electrostatic interference, dust from entering
Enter and the problem of bonnet is deformed；Solve the problems, such as that buzzer loosens the abnormal sound produced, and extend the service life of buzzer.
Therefore, the technical solution adopted in the present invention is：A kind of installation combining structure of instrument lamp-box frame and bonnet, including
Bonnet and lamp-box frame, both are fixed together by screw, be provided with the inner marginal position in upper surface of the bonnet uniform thickness,
Ring short slot is provided with contour hoop boss downwardly, the inner marginal position in lower surface of the lamp-box frame, hoop boss downwardly is located at ring
Gap is left into short slot, and between the top surface of hoop boss downwardly and the top surface of ring short slot, outer wall and the ring of hoop boss downwardly lack
Gap is left between the outer wall of groove；
Cover in the rear and be provided with sound hole area, be provided with outside the sound hole area of bonnet inwall integrally formed interior with bonnet
Annulus, outer toroid, the inside and outside annulus are coaxially disposed, and inside, sponge washer, the sponge washer are housed between outer toroid
It is higher than inside and outside annulus；Inside, the short slot quantity phase on circumferentially uniform short slot, and inside and outside annulus is provided with outer toroid
Deng, position correspondence, the rear of the lamp-box frame is welded with the buzzer just to sound hole area, and the sponge washer is carried out to buzzer
Resilient support.
As the preferred of such scheme, the liquid crystal display that rectangle is provided with the center ofthe position of the lamp-box frame is installed
Window, installs in the liquid crystal display and is each provided with two and the integrally formed bullet of lamp-box frame on the front, rear, left and right side wall of window
Property support, the resilient support includes level connection joint portion and supporting part, and the one end in the level connection joint portion is connected with lamp-box frame, water
The other end in flushconnection portion is hanging, and the support zone is in the surface of the hanging termination in level connection joint portion；All resilient support
Sustained height is arranged on, two on front side wall resilient support constitutes rectangle with two resilient support on rear wall
Arrangement, two resilient support on left side wall also constitute rectangular arrangement with two resilient support on right side wall.It is logical
Cross elastic support structure to be supported liquid crystal screen component, extended downwardly and falling towards outside with reference to what liquid crystal screen component was carried
Button hook is hung on the pcb board of lamp-box frame bottom, is realized and is clamped liquid crystal screen component from both sides up and down, it is to avoid in liquid crystal screen component
Under rock generation abnormal sound, extend the service life of liquid crystal display.
Further, the level connection joint portion of two resilient support on front side wall extends in the opposite direction so that preceding
Two resilient support on the wall of side are each independent, two resilient support on rear wall and two bullets on front side wall
Property support set-up mode it is consistent；The level connection joint portion of two resilient support extends in the same direction on left side wall, and
And two resilient support on left side wall are finally connected as a single entity, two on right side wall resilient support is with being located on left side wall
Two resilient support set-up modes it is consistent.Because the length of the left and right sides is bigger than the length of both sides up and down, therefore left and right two
The supporting part distance of two resilient support of side relatively far away from, using being wholely set, is more convenient for being molded and arranged.
Beneficial effects of the present invention：
(1) combine hoop boss downwardly and ring short slot carries out installing spacing, it is ensured that the uniformity of outer wall after assembling, and improve
The intensity of bonnet, prevents bonnet from deforming；Annular protrusion improves the seal after installing with ring short slot simultaneously, can prevent ash
Dirt enters, and can effectively prevent electrostatic from entering the normal work of lamp-box frame, interference PCB and liquid crystal display again；
(2) it is used to fix sponge washer by setting up inside and outside annulus, buzzer is welded on pcb board, and utilizes foam-rubber cushion
Enclose the elasticity of itself and elastic compression is carried out to buzzer, protection buzzer is injury-free, while shake when solving buzzer call
It is dynamic to drive the vibrations of other mechanical parts and trigger other abnormal sounds；Buzzer and instrument bonnet rigid contact are avoided, extension buzzer
Service life.
