Description

Technical Field

[0001] This utility model relates to the field of electronically controlled air horn technology, specifically an electronically controlled air horn. Background Technology

[0002] An air horn is a type of car horn, which can be divided into electric air horns, mechanical air horns, etc. Air horns use compressed air to cause a metal diaphragm to vibrate. They are mostly long and horn-shaped (cylindrical), produce loud sounds, and have a long range. They are mostly used on large and medium-sized vehicles that travel long distances, but are prohibited in urban areas.

[0003] However, existing electronically controlled air horns are generally fixed with bolts during use. When repairing or replacing them, the bolts must be completely loosened, requiring the use of special tools such as wrenches. This is especially inconvenient for commercial vehicles and construction machinery that require frequent maintenance or replacement, reducing installation and disassembly efficiency. To address these issues, the inventors have proposed an electronically controlled air horn to solve the problems mentioned above. Utility Model Content

[0004] In order to solve the problem of inconvenient installation and disassembly during the use of electronically controlled air horns, the purpose of this utility model is to provide an electronically controlled air horn.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an electrically controlled air horn, comprising a base plate and an air horn body, a mounting plate above the base plate, a first protective plate fixedly mounted on the top surface of the mounting plate, the air horn body placed inside the first protective plate, a second protective plate above the first protective plate, the second protective plate being attached to the outer surface of the air horn body, vertical plates symmetrically mounted on the top surface of the mounting plate, sliders fixedly mounted on both sides of the second protective plate, a housing fixedly mounted on one side of the vertical plate, a movable plate slidably mounted inside the housing, a first spring fixedly connected between the movable plate and the inner wall of the housing, an insert block fixedly mounted on one side of the movable plate, the insert block slidably inserted into the slider, a first anti-slip pad fixedly mounted inside the first protective plate, and a second anti-slip pad fixedly mounted inside the second protective plate. The first and second anti-slip pads are tightly attached to the outer surface of the air horn body. First, the base plate is installed in the designated position. By pulling the connecting plate, the connecting plate drives the moving plate to slide and compresses the first spring to deform. At the same time, the moving plate drives the insert block to disengage from the slider. Then, the second protective plate is moved upward, thereby moving the second protective plate away from the first protective plate, so that the air horn body can be disassembled for maintenance and replacement. Then, the repaired air horn body is placed inside the first protective plate. Next, the second protective plate is slid downward again to fit against the first protective plate. At this time, the slot opened in the slider is flush with the insert block. Then, the connecting plate is released to reset the first spring, thereby causing the moving plate to drive the insert block to insert into the slot, which facilitates the installation and disassembly of the air horn body. No tools are needed during installation and disassembly, which improves the efficiency of installation and disassembly.

[0006] When the vehicle shakes while driving, the mounting plate causes the fixed ear to descend. At the same time, one end of the guide rod is hinged inside the fixed ear, and the other end is hinged inside the movable plate. This causes the movable plate to slide on the outer surface of the slide rod and compress the second spring. Simultaneously, the spring damper works to eliminate the swaying force generated, preventing the air horn body from being damaged by prolonged shaking.

[0007] Preferably, the vertical plate has a groove, the slider is slidably disposed in the groove, the slider has a slot, the insert is slidably inserted in the slot, and a connecting plate is fixedly connected between the moving plates, the connecting plate being slidably disposed in the housing.

[0008] Preferably, a sliding rod is fixedly provided inside the base plate, a movable plate is slidably sleeved on the outer surface of the sliding rod, a guide rod is hinged inside the movable plate, a fixing ear is fixedly provided on the bottom surface of the mounting plate, one end of the guide rod away from the movable plate is hinged to the outer surface of the fixing ear, a groove is opened inside the base plate, the sliding rod is fixedly provided in the groove, the movable plate is slidably provided in the groove, and a second spring is fixedly connected between the inner wall of the groove and the movable plate, a spring damper is fixedly provided on the top surface of the base plate, and the top end of the spring damper is fixedly provided on the bottom surface of the mounting plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. By placing the air horn body inside the first protective plate, then sliding the second protective plate downwards to fit against the first protective plate, and then moving the plate to drive the insert block into the slot, it is easy to install and disassemble the air horn body. No tools are needed during installation and disassembly, which improves the efficiency of installation and disassembly.

[0011] 2. When the vehicle shakes while driving, the mounting plate causes the fixed ear to descend. At the same time, one end of the guide rod is hinged in the fixed ear, and the other end is hinged in the movable plate. This causes the movable plate to slide on the outer surface of the slide rod and compress the second spring. In conjunction with the spring damper, the generated shaking force is eliminated, preventing the air horn body from being damaged by prolonged shaking. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5As shown, this utility model provides an electrically controlled air horn, including a base plate 1 and an air horn body 5. The air horn body 5 includes an air source: an air inlet connected to the vehicle's air tank; a control switch: connected to a horn button in the driver's cab to control the opening and closing of the air horn; a generator: internally a sound-producing diaphragm, which can be made of paper, silicone, or metal. When compressed air passes through the generator, the diaphragm vibrates at high frequency to generate sound; a dual-tone horn: a combination of a high-frequency and a low-frequency unit, which alternates sound through a parallel solenoid valve; an air supply line: connecting the air source and the generator to ensure smooth transmission of compressed air to the generator; and a solenoid valve control module: used to control the air supply. The airflow is controlled in conjunction with a control switch. When the driver presses the switch, the relay coil is energized, and the compressed air flow causes the metal diaphragm to vibrate. The sound is then amplified through the megaphone to produce a loud warning. When the horn button is pressed, the electromagnetic switch closes, and compressed air supplied by the air pump enters the horn through the air pipe, driving the sound-producing diaphragm to vibrate and produce a sound. A mounting plate 2 is located above the base plate 1. A first protective plate 21 is fixedly mounted on the top surface of the mounting plate 2. The horn body 5 is placed inside the first protective plate 21. A second protective plate 22 is located above the first protective plate 21 and is attached to the outer surface of the horn body 5. A vertical plate 24 is symmetrically arranged on the top surface of the mounting plate 2. Slider blocks 23 are fixedly arranged on both sides of the second protective plate 22. A housing 3 is fixedly arranged on one side of the vertical plate 24. A movable plate 32 is slidably arranged inside the housing 3. A first spring 31 is fixedly connected between the movable plate 32 and the inner wall of the housing 3. An insert block 34 is fixedly arranged on one side of the movable plate 32. The insert block 34 is slidably inserted into the slider 23. A connecting plate 33 is fixedly connected between the movable plates 32. The connecting plate 33 is slidably arranged inside the housing 3. By pulling the connecting plate 33, the connecting plate 33 drives the movable plate 32 to slide, and compresses the first spring 31 to deform. At the same time, the movable plate 32 drives the insert block 34 to disengage from the slider 23. Then the second The protective plate 22 moves upward, thereby moving the second protective plate 22 away from the first protective plate 21, allowing the air horn body 5 to be disassembled for repair and replacement. The repaired air horn body 5 is then placed inside the first protective plate 21. Next, the second protective plate 22 is slid downward again, fitting against the first protective plate 21. At this point, the slot 231 in the slider 23 is flush with the insert block 34. Then, the connecting plate 33 is released, allowing the first spring 31 to return to its original position, which in turn causes the moving plate 32 to drive the insert block 34 into the slot 231. This facilitates the installation and disassembly of the air horn body 5 without the need for tools, thus improving the efficiency of installation and disassembly.

[0021] A first anti-slip pad 211 is fixedly installed inside the first protective plate 21, and a second anti-slip pad 221 is fixedly installed inside the second protective plate 22. The first anti-slip pad 211 and the second anti-slip pad 221 are tightly attached to the outer surface of the air horn body 5. A groove 241 is opened in the vertical plate 24, and the slider 23 is slidably installed in the groove 241. A slot 231 is opened in the slider 23, and the insert 34 is slidably inserted into the slot 231.

[0022] By adopting the above technical solution, when the second protective plate 22 is attached to the top of the first protective plate 21, the first anti-slip pad 211 and the second anti-slip pad 221 are tightly attached to the outer surface of the air horn body 5, thereby preventing the air horn body 5 from shaking inside the first protective plate 21 and the second protective plate 22.

[0023] A sliding rod 4 is fixedly installed inside the base plate 1. A movable plate 41 is slidably fitted on the outer surface of the sliding rod 4. A guide rod 43 is hinged inside the movable plate 41. A fixing ear 44 is fixedly installed on the bottom surface of the mounting plate 2. The end of the guide rod 43 away from the movable plate 41 is hinged to the outer surface of the fixing ear 44. A groove 101 is opened inside the base plate 1. The sliding rod 4 is fixedly installed in the groove 101. The movable plate 41 is slidably installed in the groove 101. A second spring 42 is fixedly connected between the inner wall of the groove 101 and the movable plate 41. A spring damper 45 is fixedly installed on the top surface of the base plate 1. The top end of the spring damper 45 is fixedly installed on the bottom surface of the mounting plate 2.

[0024] By adopting the above technical solution, when the vehicle shakes during driving, the mounting plate 2 causes the fixed ear 44 to descend. At the same time, one end of the guide rod 43 is hinged in the fixed ear 44, and the other end is hinged in the movable plate 41, thereby causing the movable plate 41 to slide on the outer surface of the slide rod 4 and compress the second spring 42. At the same time, the spring damper 45 is used to eliminate the shaking force generated, so as to avoid damage to the air horn body 5 due to long-term shaking.

[0025] Working principle: First, the base plate 1 is installed in the designated position. By pulling the connecting plate 33, the connecting plate 33 drives the moving plate 32 to slide and compress the first spring 31 to deform. At the same time, the moving plate 32 drives the insert block 34 to disengage from the slider 23. Then, the second protective plate 22 is moved upward, thereby moving the second protective plate 22 away from the first protective plate 21, so that the air horn body 5 can be disassembled for maintenance and replacement. Then, the repaired air horn body 5 is placed in the first protective plate 21. Next, the second protective plate 22 is slid downward again and fits against the first protective plate 21. At this time, the slot 231 opened in the slider 23 is flush with the insert block 34. Then, the connecting plate 33 is released, so that the first spring 31 is reset, and the moving plate 32 drives the insert block 34 to insert into the slot 231, which facilitates the installation and disassembly of the air horn body 5. No tools are needed for installation and disassembly, which improves the efficiency of installation and disassembly.

[0026] When the vehicle shakes during driving, the mounting plate 2 causes the fixed ear 44 to descend. At the same time, one end of the guide rod 43 is hinged in the fixed ear 44, and the other end is hinged in the movable plate 41. This causes the movable plate 41 to slide on the outer surface of the slide rod 4 and compress the second spring 42. Simultaneously, the spring damper 45 works to eliminate the shaking force generated, preventing the air horn body 5 from being damaged by bumps due to long-term shaking.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
