Description

Technical Field

[0001] This utility model relates to the field of basin-shaped electric horn technology, and more specifically, to a breathable, waterproof and heat-dissipating structure for a basin-shaped electric horn. Background Technology

[0002] The cone-shaped electric horn is a widely used warning and alert device in vehicles such as cars, motorcycles, and electric vehicles. Its name comes from its shape, typically resembling a cone or horn. It operates on the principle of electromagnetic drive, utilizing the magnetic field generated by an electric current passing through a coil to drive a diaphragm (or vibrating plate) to vibrate rapidly, thus producing sound. The cone-shaped electric horn has a relatively simple yet sophisticated structure, typically including a coil, iron core, diaphragm, contacts, and a housing. Its loud and penetrating sound effectively transmits warning information in complex traffic environments, making it a crucial component for ensuring driving safety.

[0003] A search revealed an existing patent (publication number: CN219107646U) that discloses a basin-shaped electric horn assembly, including a housing, an upper plate on the housing, a diaphragm on the upper plate, a resonating plate on the diaphragm, a lower plate, an insulating plate, and a lower plate connected to the upper plate by screws, contacts on the upper and lower plates, two contacts in contact with each other, an armature on the upper plate, a moving iron core on the armature, a connector on the housing, a fixing block fixedly connected to the connector, a coil frame on the housing, and a stationary iron core on the moving iron core. This utility model, by incorporating components such as a fixing block, a connecting sleeve, and a limiting bracket, allows the connector to be inserted into the connector by the limiting bracket engaging the locking block within the fixing block, thus limiting the connection and ensuring a more stable and secure connection without loosening.

[0004] However, during use, the connection between the connector and the fixing block is not sealed, which may allow moisture, dust, and other impurities to enter the device, affecting the speaker's performance and lifespan. Secondly, the patent does not mention any heat dissipation measures; the heat generated by the speaker during high-frequency operation cannot be effectively dissipated, easily leading to contact erosion, coil aging, and other problems, thus affecting the product's long-term stability and reliability. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a basin-shaped electric horn with a breathable, waterproof and heat dissipation structure to solve the problems of poor sealing and poor waterproofing.

[0010] Preferably, the auxiliary heat dissipation device includes: a heat dissipation ring fixedly installed on one side of the basin-shaped electric horn body; and heat dissipation fins fixedly installed on one side of the basin-shaped electric horn body.

[0011] Preferably, the heat dissipation fins are provided in multiple sets, and the multiple sets of heat dissipation fins are equidistantly installed on the rear side of the basin-shaped electric horn body, and the multiple sets of heat dissipation fins are disposed inside the heat dissipation ring.

[0012] Preferably, the thixotropic sealant one and thixotropic sealant two are uniformly applied to the outer surface of the iron core bolt by pressure.

[0013] Preferably, a threaded groove is provided on the rear side of the basin-shaped electric horn body, the threaded groove is used for installing the iron core bolt, and the interior of the threaded groove is filled with thixotropic sealant.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a method where, when the vehicle is started, current flows through the iron core bolt into the cone-shaped electric horn body, driving the diaphragm to produce sound. The waterproof bolt structure, with a thin nut threadedly connected to the iron core bolt, along with thixotropic sealant type one and type two, ensures a tight seal at the threaded connection, preventing moisture and dust from entering. Simultaneously, the second chassis is fixed to the bottom of the first chassis, further enhancing structural stability. The advantages of this design are improved waterproof performance and vibration resistance under complex road conditions, extending the horn's service life.

[0016] This invention utilizes a waterproof and breathable heat dissipation structure to maintain internal and external air pressure balance through a breathable membrane when the speaker is operating, while preventing moisture from entering. A fixed chassis and insert base protect the breathable membrane from damage caused by splashing water or mud. The auxiliary heat dissipation device, with its heat dissipation rings and multiple equidistantly installed heat dissipation fins, rapidly dissipates heat generated inside the speaker to the outside through gas exchange and heat conduction. This design improves the speaker's heat dissipation efficiency and waterproof performance, while the air pressure regulation function of the breathable membrane ensures stable sound quality at high altitudes or in complex environments, further extending the product's lifespan.
