Title: THE AIR COMPRESSOR CONSTRUCTION OF

AUTOMOBILE AIR HORN

Technical Field

The present invention relates to an air horn engaged at a truck or a

cargo vehicle, and in particular to a compressor structure of a vehicle air horn

which may be directly connected with an air horn by improving a structure of a

compressor which supplies air to an air horn and may be constructed in a

simple structure, so that a manufacture is simple, and an engaging operation is

easy for thereby enhancing the convenience of use.

Background Art

Generally, a horn of a vehicle is used when a certain obstacle such as a

pedestrian or a vehicle is in the middle of a running vehicle or is used so as to

inform a running state of a corresponding vehicle. It is usually installed at a

center portion of a steering handle of a vehicle for generating a certain alarm

sound when a driver presses the same.

The horn is classified into an electric/electronic type or an air type. The

air type horn is generally installed at a large scale truck or a bus which has an

air compressor, and an electric horn is generally installed at a passenger vehicle.

However, many drivers of a passenger vehicle prefer to install an air horn which

generates a natural sound like a ship horn and a horn sound as compared to an

electric/electronic type horn and exchange the old horns with air horns.

Figure 1 is a schematic cross sectional view illustrating a structure that

a compressor is engaged at a conventional air horn.

A conventional air horn 1 is fixed at a ceiling, roof or engine room of a

vehicle (truck, cargo vehicle and bus) by a bracket 2 for thereby generating a

large scale horn or horn sound. As shown in Figure 1 , the air horn 1 is provided

with a compressor 3 capable of generating a high pressure compressed air, a

supply tube 4 for supplying the compressed air of the compressor 3, and a

trumpet shaped conical tube 6 for spreading an echoed sound which is

generated as the compressed air supplied from the supply tube 4 vibrates the

vibration plate 5. Here, the compressor 3 is electrically connected with a relay

switch (not shown), and the relay switch is electrically connected with a power

apparatus (not shown) of the vehicle.

When the switch (not shown) connected with the air horn 1 at the center

of the steering handle of the vehicle is pressed, the compressor 3 allows a

rotator S to fast rotate, and the pressure of the gas increases by the torque due

to the large flow energy, and the high pressure compressed air is distributed to

the vibration plate 5 through the supply tube 4 for thereby spreading the echoed

sound to the conical tube 6, so that an approaching or emergency state is

informed to the vehicle or pedestrian based on sound waves.

As shown in Figure 1 , the conventional compressor 3 is connected with

the nipple 3a of one side and the nipple 2a of the bracket 2 using the supply

tube 4, so that the connection is possible only when the user directly connects

the supply tube 4 for thereby causing many inconveniences. When the supply

tube 4 is loosely engaged at the nipples 2a and 3a, it may be escaped, so that it

is not easy to engage the same.

In addition, as shown in Figure 1 , in the conventional air compressor,

external air is inputted into the interior through an inlet hole 3b at one side of the

body, and the inputted air is guided and compressed by the rotator S and is

supplied through a discharge hole 3c. The inlet hole 3b for inputting air into the

body and the discharge hole 3c for supplying should be disadvantageously

installed for thereby resulting in complicated structures.

The supply tube 4 connecting the air horn and the compressor 3 is

made of a synthetic resin such as rubber or plastic, so that it may be

transformed or damaged when it is used for a long time for thereby producing

many problems when in use.

Disclosure of Invention

Accordingly, it is an object of the present invention to overcome the

above-described conventional problems encountered in the conventional art.

It is another object of the present invention to provide a compressor

structure of a vehicle air horn which may be directly connected at an air horn by

improving a structure of a compressor supplying air to an air horn, and a

structure is simple, and a manufacture is easy, and an easier engagement is

implemented for thereby obtaining a convenience when in use.

To achieve the above objects, there is provided a compressor which is

connected with a bracket of an air horn and receives a rotator S in a body and is

sealed by a cover and supplies a high pressure compressed air A, comprising a

discharge port which is formed at a front end of the body for discharging a high

pressure compressed air based on an operation of a rotator S; and an engaging

part which is engaged at a bracket of the air horn together with an inlet hole for

inputting an external air at a front end of the cover using a thread and has a

discharge path communicating with the discharge port for thereby supplying

compressed air.

Best Mode for Carrying Out the Invention

The preferred embodiments of the present invention will be described

with reference to the accompanying drawings.

Figure 2 is a view illustrating a structure of a compressor according to

the present invention, and Figure 3 is a view illustrating a construction that a

compressor is engaged according to the present invention.

The present invention relates a compressor, which is connected with

the bracket 2 of the air horn land receives the rotator S in the body 21 and is

sealed using a cover 25 for thereby supplying a high pressure compressed air A.

Like the conventional air horn 1 , the present invention comprises a compressor

20 for generating high pressure compressed air, and a trumpet shaped conical

tube 6 for spreading echoed sound as the compressed air from the compressor

20 vibrates the vibration plate 5. The compressor 20 is electrically connected

with a relay switch (not shown), and the relay switch is electrically connected

with a power apparatus (not shown) of the vehicle.

The compressor 20 according to the present invention comprises a

body 21 and a cover 25. Differently from the conventional art, it may be directly

connected with the air horn 1 , so that an engagement is easy, and many

conveniences are obtained when in use.

The body 21 according to the present invention is provided with a

discharge port 22 for discharging high pressure compressed air as the rotator S

rotates. As shown in Figures 2 and 3, a concave groove is formed at a portion of

the body 21 at which the high pressure compressed air is discharged. A

discharge port 22 having a through hole is engaged at the concave groove. As

compared to the conventional compressor 3, a concave groove is formed at the

portion in which the compressed air A is discharged, and the discharge port 22

is engaged at the concave groove, so that the structure is very simple.

The cover 25 according to the present invention is thread-engaged at

the bracket 2 of the air horn 1 using the thread 28a together with the inlet hole

26 for inputting external air and communicates with the discharge port 22 along

with the disposed engaging port 28 having a discharge path 27 for supplying

compressed air. As shown in Figures 2 and 3, the cover 25 includes an inlet

hole 26 formed at an outer surface of the front end, for thereby inputting an

external air into the body 21. As compared to the conventional art in which it is

formed at the body, the inlet hole 26 is formed at the cover 25 for thereby

achieving an easier manufacture.

The cover 25 includes an engaging part 28. As shown in Figure 2, the

engaging part 28 has a thread 28a as shown in Figure 2 and is directly engaged

at the bracket 2 of the air horn 1. Here, a thread groove 2a is formed at the

bracket 2 of the air horn 1 and is sealinginly engaged with the thread 28a of the

cover 25. The engaging part 28 has a discharge path 27 in the inner side and

communicates with the discharge port 22 of the body 21 for thereby supplying

the compressed air to the air horn 1.

As shown in Figures 2 and 3, the compressor 20 is engaged with the

body 21 and the cover 25 using the bolts. The compressor 20 is directly

engaged with the bracket 2 of the air horn 1 through the engaging part 28 of the

cover 25. Namely, the thread groove 2a of the bracket 2 and the thread 28a of

the engaging part 28 are engaged with each other.

When the switch (not shown) is pressed so as to generate sound from

the air horn 1 provided at the steering handle (not shown) of the vehicle, the

compressor 20 starts operating. External air is inputted into the body 21 from

the inlet hole 26 of the cover 25, and the inputted air is flow in the direction

shown by the arrow in the drawing.

As shown in Figure 3, the inputted air of the inlet hole 26 allows the

pressure of the gas to increase by the operation of the rotator S, and the

generated high pressure air A is discharged through the through hole 22a of the

discharge port 22. As shown in Figure 3, the compressed air discharged

through the through hole 22a of the discharge port 22 is discharged through the

discharge path 27 of the engaging part 28 and is inputted into the flow path

formed at the bracket 2 of the air horn 1 and is sprayed toward the vibration

plate 5 while spreading echoed sound toward the conical tube 6, so that the

vehicle or pedestrian is informed of an approaching state of a vehicle or an

emergency situation.

As described above, the compressor 20 according to the present

invention may be directly connected with the air horn 1 , so that any one can

easily engage the same for thereby enhancing the use of the same, and the

internal structure of the compressor 20 is simple, and the manufacture of the

same is easy.
