Abstract

The utility model discloses a vehicle horn, comprising a chassis, a diaphragm and an iron core assembly. One end of the chassis is attached to and fixed with the diaphragm, and the end face of the other end is fixedly equipped with the iron core assembly. The end face at the attached end of the chassis and the diaphragm is equipped with a groove protruding outwards, the iron core assembly is fixedly arranged on the outer end face of the chassis groove, and a penetrated slotted hole is arranged on the chassis groove. The slotted hole arranged on the chassis groove has a U-shape, and the U-shaped slotted hole surrounds the outside of the iron core assembly. By employing the above structure, the adjustment for an air gap of the iron core assembly can be realized just by using common tools to prize the U-shaped slotted hole, such as a screwdriver, etc. The adjustment is simple and convenient without needing to add other adjusting structure or improve the product precision, compared with the prior art, the product defective rate is lower.

Description

Automobile horn

Technical field

The utility model relates to a kind of automobile horn.

Background technology

At present, the automobile horn of band laminated core structure structure,, adhesive better performances big because of the area coverage of its core assembly structure becomes a kind of of widespread use on the automobile horn; But the automobile horn of this band laminated core structure structure is because core area is bigger, therefore also higher to size of gaps and uniformity coefficient requirement all around; And the automobile horn of existing band laminated core structure structure; Its air gap adjustment mainly contains two kinds of methods, and a kind of is that air gap is non-adjustable, is guaranteed with transferring pad by element precision fully; Element precision is had relatively high expectations, thereby cause defect rate higher; Another kind is that air gap is adjustable, is made up of the nut bolt structure, changes air gap through the manual setting nut location, and efficient is low, product structure is complicated.

Summary of the invention

To the deficiency of prior art, it is a kind of simple in structure and be convenient to regulate the automobile horn of air gap that the utility model provides.

For realizing above-mentioned purpose; The utility model provides a kind of automobile horn, comprises chassis, diaphragm, core assembly, and an end on said chassis and diaphragm fit and set firmly; Be installed with core assembly on the other end end face on said chassis; This end end face that said chassis and diaphragm fit is provided with the groove to outer lug, and described core assembly is installed on the outside end face of chassis groove, and said chassis groove is provided with the slotted eye of perforation.

It is U-shaped that the utility model can further be set to the said slotted eye that is opened on the groove of chassis, and the slotted eye of said U-shaped structure is enclosed in the outside of core assembly.

The utility model also can further be set to the circle that is shaped as on said chassis, and the U-lag hole number on the said circular base plate is several, and several U-lag holes are circumference uniform distribution.

The beneficial effect of the utility model is: adopt said structure; Only need to prize the U-lag hole on the chassis through common tools such as screwdrivers; And can realize adjustment to the core assembly air gap, and regulate simple and conveniently, and do not need to set up in addition other adjustment structures or improve the precision of product; Compared with prior art, the defect rate of its product is lower.

Fig. 3 is the structural representation on chassis in the utility model.

Embodiment

Like Fig. 1,2, provided a kind of automobile horn shown in 3; Comprise chassis 1, diaphragm 2, core assembly 3; One end on said chassis 1 and diaphragm 2 fit and set firmly, and are installed with core assembly 3 on the other end end face on said chassis 1, and said chassis 1 is provided with the groove 11 to outer lug with this end end face that diaphragm 2 fits; Described core assembly 3 is installed on the outside end face of chassis groove 11, and said chassis groove 11 is provided with the slotted eye 111 of perforation.The said slotted eye 111 that is opened on the chassis groove 11 is U-shaped; And the slotted eye 111 of said U-shaped structure is enclosed in the outside of core assembly 3; Said chassis 1 be shaped as circle, U-lag hole 111 quantity on the said circular base plate 1 are two, and said two U-lag holes 111 are circumference and are symmetrical set.

Adopt said structure; Only need to prize The One On The Chassis U-lag hole 111 through common tools such as screwdrivers; And can realize adjustment to core assembly 3 air gaps, and regulate simple and conveniently, and do not need to set up in addition other adjustment structures or improve the precision of product; Compared with prior art, the defect rate of its product is lower.
