Description

Waterproof dirt-proof car loudspeaker

Technical Field

The utility model discloses be applied to the automobile parts field, be particularly useful for automotive electronics electrical apparatus field, specific waterproof dirt-proof car horn that says so.

Background

With the rapid development of the automobile industry, automobiles become daily transportation means for common people. The horn is an audible signal device of an automobile. During the driving process of the automobile, a driver sends out necessary acoustic signals according to needs and regulations, and the acoustic signals warn pedestrians and attract the attention of other vehicles, so that the traffic safety is ensured, and meanwhile, the acoustic signals are also used for transmitting the signals.

According to the realization mode of product technology, the automobile electric horn can be divided into mechanical contact type, fixed frequency electronic type, follow-up frequency electronic type and hybrid electromechanical horn. The most widely used is the mechanical contact type,

when the automobile runs in rainy days or runs on roads with water, the water on the ground is flushed into the front engine room, and the waterproof performance of electrical appliances such as a horn and the like arranged in the front engine room becomes an important consideration. At present, when a vehicle type adopting a mechanical contact type horn as shown in fig. 1 is arranged at the front end, the horn is arranged above a front anti-collision beam or an energy absorption box, an opening of the horn faces the front anti-collision beam or the energy absorption box, and the front anti-collision beam or the energy absorption box is used for blocking water for the horn. However, this solution greatly limits the area of the horn and only provides good waterproof performance for the horn. On the other hand, whether the automobile runs on a silt road or a common road, foreign matters such as dust inevitably enter the front engine room and then enter the opening of the horn. After the vehicle is used for a long time, a lot of foreign matters can be accumulated in the loudspeaker, the sounding and reminding functions of the loudspeaker are influenced, and the durability and the reliability of the vehicle cannot be well guaranteed.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art, provides a waterproof and dustproof automobile horn which has low cost and waterproof and dustproof functions,

in order to achieve the above object, the utility model discloses specifically adopt following technical scheme:

including installing support, loudspeaker body, socket and shell, the shell is installed in the below region of loudspeaker body, and the front end of shell and rear end position all have one section y to the weakening groove that runs through, and the shell front and back end is + x/-x direction promptly because there is the weakening groove, but consequently warp the back joint in the below of loudspeaker body, realizes not having the connection of extra fastener.

The front end of the shell is a closed surface, so that the effects of water resistance, mud resistance and dust resistance can be realized, and ripple-shaped sound emitting holes are formed in the rear end part of the shell.

The front end part of the horn body, namely the + x direction, is provided with two limiting ribs, and the rear end part, namely the-x direction, is provided with a limiting rib.

The upper surface of loudspeaker body with the shell inboard, the inboard z of the strengthening rib of loudspeaker body and shell 4 to the clearance all be 0.2mm, guaranteed the shell joint be in loudspeaker body the time z to spacing.

The y-direction clearance between the rear end of the shell and the horn body and between the rear end of the horn body and the limiting boss is 0.5mm, so that the y-direction positioning and limiting of the shell when the shell is clamped on the horn body are guaranteed.

The utility model provides a car horn's structure can realize well that car horn's the water that hinders mud and hinders dirt effect, and low cost, and it is convenient to install, the dependable performance.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings; it should be emphasized that the embodiments described herein are illustrative of the invention and are not limiting to the scope of the invention.

As shown in fig. 2, 3 and 5, the horn device comprises a mounting bracket 1, a horn body 2, a socket 3 and a shell 4, wherein the shell 4 is mounted in the lower area of the horn body 2. The front end and the rear end of the shell 4 are provided with a section of weakening groove 7 which is penetrated through in the y direction, and the front end and the rear end of the shell 4, namely the + x/-x direction, can be clamped below the horn body 2 after deformation due to the weakening groove 7, so that connection without additional fasteners is realized.

As shown in fig. 2 and 3, the front end of the housing 4 is a closed surface, so that the effects of water resistance, mud resistance and dust resistance can be realized; the rear end portion of the housing 4 is provided with ripple-shaped sound emitting holes 6, so that the sound transmission and the sound quality of the automobile horn can be ensured.

As shown in fig. 2, the front end of the horn body 2, i.e., the + x direction, has two limiting ribs 5, and the rear end thereof, i.e., the-x direction, has one limiting rib 5.

As shown in fig. 5, the z-direction gaps between the upper surface of the horn body 2 and the inner side of the housing 4, and between the inner side of the horn body 2 and the reinforcing ribs 8 of the housing 4 are all 0.2mm, so that the housing 4 is guaranteed to be clamped in the horn body 2 and is limited in the z-direction.

As shown in fig. 5, the y-direction gap between the rear end of the housing 4 and the horn body 2 and between the rear end of the housing and the limiting boss is 0.5 mm. Thereby guarantee the location and the spacing of y orientation when shell 4 joint is at loudspeaker body 2.
