Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a moisture-proof and mildew-proof automobile horn. Background Art

[0002] The car horn is an important sound device for the car, mainly used to issue warnings or prompts to ensure driving safety. A typical car horn system mainly consists of the following parts: Button or switch: located on the steering wheel, the driver activates the horn by pressing the button. Relay: when the button is pressed, the relay will connect the circuit and allow current to flow to the horn; Diaphragm: when current passes through the coil, the diaphragm will vibrate and produce sound; Coil: located near the diaphragm, when current passes, it will generate a magnetic field to push the diaphragm to vibrate; Electromagnet: In some horn designs, electromagnets are used to replace or assist the role of the coil. Resonance chamber: used to amplify and optimize the sound produced by the diaphragm; Circuit connection: including wires and connectors connecting buttons, relays and horns; Fixing bracket: used to fix the horn to a certain part of the car, usually the front bumper or engine compartment.

[0003] For the purpose of moisture and mildew prevention, car horns are generally equipped with a plastic or metal dust cover on the outside to block the invasion of fine dust and prevent water vapor from invading the inside of the horn, causing the electromagnetic components to become damp and moldy. However, the setting of the dust cover will weaken and limit the sound of the horn on the one hand, and on the other hand, a large amount of fine dust will accumulate on the surface of the dust cover over time, which can only be cleaned manually, and it is difficult to clean the car horn with a normal family car wash. At the same time, the fully enclosed dust cover will isolate the gas in the horn, similar to a watch dial. Once it comes into contact with water vapor, the air inside the horn will evaporate and form water mist that is difficult to eliminate. The presence of water mist will aggravate the mold and moisture inside the horn on the one hand, and on the other hand, it will also affect the sound of the horn.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original moisture-proof and mildew-proof car horn. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a moisture-proof and mildew-proof vehicle horn to solve the problem that the fully enclosed dust cover proposed in the above-mentioned background technology will isolate the gas in the horn inside, similar to the dial of a watch, and once it comes into contact with water vapor, the air inside the horn will vaporize and form water mist that is difficult to eliminate. The presence of water mist will aggravate the mold and moisture inside the horn on the one hand, and will also affect the sound of the horn on the other hand.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a moisture-proof and mildew-proof vehicle horn, comprising a horn body, wherein an elastic net is laid corresponding to the sound part of the horn body and can transmit the vibration inside the horn body to the outside.

[0007] Preferably, the elastic net is designed in the shape of a spirally wound metal wire, and adjacent spiral metal wires of the elastic net fit together.

[0008] Preferably, the elastic net is arranged in a shape of a center concave and surrounding convexities that matches the shape of the sound part of the speaker body.

[0009] Preferably, an inner ring is fixed to the inner end of the spirally wound metal wire of the elastic net, and an inner elastic telescopic rod is arranged at an equal angle between the inner ring and the speaker body.

[0010] Preferably, the inner elastic telescopic rod is composed of three parts: a telescopic rod, a fixed sleeve and an internal elastic member, and the outer end of the telescopic rod is fixed to the outer wall of the inner ring, and the base of the fixed sleeve is fixedly connected to the speaker body.

[0011] Preferably, an outer ring is fixed to the outer end of the spirally wound metal wire of the elastic net, and an outer elastic telescopic rod is arranged at an equal angle between the outer ring and the speaker body.

[0012] Preferably, the outer elastic telescopic rod is composed of three parts: a telescopic rod, a fixed sleeve and an internal elastic member, and the outer end of the telescopic rod is fixed to the outer wall of the outer ring, and the base of the fixed sleeve is fixedly connected to the speaker body.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the driver presses the horn button on the steering wheel, the horn is powered on to generate a magnetic field. The metal inner ring and the metal outer ring located at the sound part of the horn body will synchronously sense the magnetic field, and the electromagnetic field inside the horn body will synchronously generate an outward repulsive force on the inner ring and the outer ring. Since the inner ring and the outer ring are different in size, the electromagnetic field inside the horn body also generates an outward repulsive force on the inner ring and the outer ring. As a result, the inner ring and the outer ring will synchronously expand outward and stretch the corresponding inner elastic telescopic rod and the outer elastic telescopic rod when the horn sounds, and the inner ring and the outer ring will expand outward at different speeds, which will cause the spiral elastic net that originally had no gap to be stretched apart, and the stretched spiral elastic net will help the sound of the horn to pass through; When the driver no longer presses the horn button on the steering wheel, the electromagnetic phenomenon is disconnected, and the repulsive force on the inner ring and the outer ring is interrupted. Under the resetting action of a number of inner elastic telescopic rods and an outer elastic telescopic rod, the inner ring and the outer ring are driven to quickly reset, so that the elastic net is reset and the gap is eliminated. Moreover, the driver usually presses the horn in a more emergency situation, and the pressure is mostly fast, high-frequency and violent. For the horn body, the horn sound is short, rapid and loud, and more penetrating. At the same time, the inner ring and the outer ring will also perform differential reciprocating vibration quickly and at a high frequency, which can shake off the fine dust gathered on the outside of the elastic net. Moreover, the differential vibration will open the gap of the spirally coiled elastic net, facilitating the transmission of the sound of the horn body.

[0014] The present invention adopts a special elastic net to replace the traditional fully enclosed dust cover. When the horn is not in use, the elastic net is fully enclosed to isolate dust and moisture. When the horn is in use, the elastic net will automatically open and vibrate according to the driver's habit of pressing the horn and stably receive electromagnetic induction. The elastic net is in an unclosed state when opened, which is conducive to the discharge of moisture inside the horn and the propagation of sound (increasing the frequency of internal and external gas exchange is also an important way to prevent moisture and mildew). Moreover, every time the driver presses the horn, it is equivalent to a vibration cleaning of the dust outside the horn body. Without extra energy consumption and effort, it solves the problem that fine dust on the surface of existing car horns is easy to accumulate in large quantities and is difficult to clean.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5The present invention provides a technical solution: a moisture-proof and mildew-proof vehicle horn, comprising a horn body 1, wherein the sound part of the horn body 1 is paved with an elastic net 4 that can transmit the internal vibration of the horn body 1 to the outside.

[0019] The elastic net 4 is designed to be in the shape of a spirally wound metal wire, and adjacent spiral metal wires of the elastic net 4 fit each other.

[0020] The elastic net 4 is arranged in a shape of a center concave and surrounding convexities matching the shape of the sound part of the speaker body 1 .

[0021] An inner ring 2 is fixed to the inner end of the spirally wound metal wire of the elastic net 4 , and an inner elastic telescopic rod 21 is arranged at an equal angle between the inner ring 2 and the speaker body 1 .

[0022] The inner elastic telescopic rod 21 is composed of three parts: a telescopic rod, a fixed sleeve and an internal elastic member. The outer end of the telescopic rod is fixed to the outer wall of the inner ring 2, and the base of the fixed sleeve is fixedly connected to the speaker body 1.

[0023] An outer ring 3 is fixed to the outer end of the spirally wound metal wire of the elastic net 4 , and an outer elastic telescopic rod 31 is arranged at an equal angle between the outer ring 3 and the speaker body 1 .

[0024] The outer elastic telescopic rod 31 is composed of three parts: a telescopic rod, a fixed sleeve and an internal elastic member. The outer end of the telescopic rod is fixed to the outer wall of the outer ring 3 , and the base of the fixed sleeve is fixedly connected to the speaker body 1 .

[0025] First of all, it is necessary to clarify the sound-generating principle of car horns: when the driver presses the horn button on the steering wheel, the circuit is closed, and current flows from the car's battery to the horn; when the current passes through the coil inside the horn, a magnetic field is generated around the coil; this magnetic field interacts with the fixed iron core under the coil; the change in the magnetic field causes the iron core to generate magnetic force, which attracts or pushes the diaphragm (usually metal) under the coil; the movement of the diaphragm is reciprocating, that is, it is attracted and then pushed out; the rapid vibration of the diaphragm causes the surrounding air to vibrate as well, and these vibrating air waves are sound waves. The sound waves spread and are eventually captured by the human ear, and we hear the sound of the horn.

[0026] In general, the sound-making principle of car horns is to generate a magnetic field through electric current. The magnetic field acts on the diaphragm to make it vibrate. The vibration of the diaphragm is transmitted to the air to generate sound waves, and finally make a sound. The vocal resonance cavity is used to enhance and optimize these sound waves.

[0027] Embodiment: When the driver presses the horn button on the steering wheel, the horn is powered on to generate a magnetic field and make a sound based on the above, and when an electromagnetic field is generated inside the horn body 1, the metal inner ring 2 and the metal outer ring 3 located in the sound part of the horn body 1 will synchronously sense the existence of the magnetic field, and the electromagnetic field inside the horn body 1 will synchronously generate an outward repulsive force on the inner ring 2 and the outer ring 3 (although the elastic net 4 is also made of metal, the elastic net 4 is designed in a filamentous shape, and the electromagnetic influence of the smaller fineness is negligible compared with the inner ring 2 and the outer ring 3). Since the inner ring 2 and the outer ring 3 are distinguished in size, the electromagnetic field inside the horn body 1 also generates an outward repulsive force on the inner ring 2 and the outer ring 3. As a result, the inner ring 2 and the outer ring 3 are synchronously expanded outward when the horn sounds and stretch the corresponding inner elastic telescopic rod 21 and the outer elastic telescopic rod 31, and the inner ring 2 and the outer ring 3 will expand outward at different speeds, which will cause the spiral elastic net 4 that originally had no gap to be pulled apart, and the pulled spiral elastic net 4 helps the sound of the horn to pass through; When the driver no longer presses the horn button on the steering wheel, the electromagnetic phenomenon is disconnected, and the repulsive force on the inner ring 2 and the outer ring 3 is interrupted. Under the resetting action of the inner elastic telescopic rods 21 and the outer elastic telescopic rods 31, the inner ring 2 and the outer ring 3 are quickly reset to reset the elastic net 4 and eliminate the gap. Moreover, the driver usually presses the horn in a more emergency situation, and most of the pressing is fast, high-frequency and violent. For the horn body 1, the horn sound is short, rapid and loud, and more penetrating. At the same time, the inner ring 2 and the outer ring 3 will also perform differential reciprocating vibration quickly and at high frequency, which can shake off the fine dust gathered on the outside of the elastic net 4, and the differential vibration will open the gap of the spirally coiled elastic net 4, so as to facilitate the transmission of the sound of the horn body 1.

[0028] The present invention adopts a special elastic net 4 to replace the traditional fully enclosed dust cover. When the horn is not in use, the elastic net 4 is fully enclosed to isolate dust and moisture. When the horn is in use, the elastic net 4 will automatically open and vibrate according to the driver's habit of pressing the horn to stably receive electromagnetic induction. The elastic net 4 is in an unenclosed state when opened, which is conducive to the discharge of moisture inside the horn and the propagation of sound. Moreover, each time the driver presses the horn, it is equivalent to a vibration cleaning of the dust outside the horn body 1. Without additional energy consumption and effort, it solves the problem that fine dust on the existing car horns is easy to accumulate on the surface and is difficult to clean.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
