Flanging-preventing horn of automobile

Abstract

The invention discloses a flanging-preventing horn of an automobile. The flanging-preventing horn comprises an upper horn shell and a lower horn shell. An upper connecting edge is arranged on the upper horn shell, and a lower connecting edge is arranged on the lower horn shell. The upper connecting edge and the lower connecting edge are fixedly connected through a plurality of fixing bolts and fixing nuts. A horn mouth communicated with an inner cavity of the lower horn shell is formed in one side of the lower horn shell, the outer side of the upper connecting edge and the outer side of the lower connecting edge are covered with two semicircular U-shaped flanging-preventing clamping blocks, and clamping grooves matching the upper connecting edge and the lower connecting edge are formed in the inner sides of the two semicircular U-shaped flanging-preventing clamping blocks. A plurality of bolt fixing holes matching the fixing bolts are evenly formed in the two semicircular U-shaped flanging-preventing clamping blocks, and an annular sealing gasket is arranged in the position, between the upper connecting edge and the lower connecting edge, in the two semicircular U-shaped flanging-preventing clamping blocks.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile anti-flange horn. Background technique [0002] With the improvement of people's living standards, the number of cars has reached an unprecedented scale, and auto parts have also developed rapidly. People's requirements for auto parts are getting higher and higher. Car horns are a vital part of auto parts. Ring, it provides an important guarantee for people's safe travel. At present, the car horn structure is similar, and its structure mainly includes: a horn upper shell and a horn lower shell, an upper connecting edge is arranged on the horn upper shell, and a lower connecting edge is arranged on the horn lower shell, The upper connecting edge and the lower connecting edge are fixedly connected by a plurality of fixing bolts and fixing nuts, and a bell mouth communicating with the inner cavity of the lower horn casing is provided on one side of the lower horn casing.

Problems solved by technology

Since the connecting edge between the upper shell of the horn and the lower shell of the horn is a relatively weak structure, when tightening the horn shell with fixing bolts and fixing nuts, especially when multiple fixing bolts and fixing nuts are tightened, due to tightening The degree of connection is different, and the connecting edge is easy to deform, causing the connecting edge to turn up and flanging, leaving a gap between the contact surface with the horn shell. In this way, this kind of car horn cannot form a seal for the inside of the shell. Water ingress causes corrosion of the electronic components and contacts inside the horn shell, shortening the service life of the car horn; at the same time, the existing horns are generally sealed with glue, which has poor sealing effect, easily causes air leakage, and damages the horn. the sound of the impact
