This detailed description, while continuing to use audible warning devices (11) with outside for connection controlled has been revealed.
The invention, it is designed to use the horn at maximum level and performance in all existing areas.
The invention, generally describes a horn structure. Before installing the horn cover (10) is used to prevent the electronic components from being affected by the outdoor temperature. The said cover (10) is mounted to the open area socket (9). So the electronical unit control (4) makes it completely isolated from the outside.
For the horn to work, the continuous electrical voltage from the vehicle must be transmitted to the horn coil intermittently with certain frequency and PWM values.
Continuous electrical voltage coming from the vehicle, it is sent to the electronic control unit input terminal sockets (6) via the input terminals (1). The design and geometric dimensions of these slots, made to provide physical connection input terminals (1) and electronical control unit (4). The electrical voltage of the horn coming to the electronic control unit (4) operates active and passive electronic components with embedded software, by activating the micro processor located on the electronic control unit (4). Output terminals (2) located inside the electronic control unit output terminal slots (7) makes the horn work electrical voltage is transmitted to the coil of the horn. Differences in tolerance ranges caused by production make up differences in the working performance of each horn. For each horn software different a variable must be defined in order to eliminate the differences observed at the end of production. Horn socket (9) with cover (10) is in the closed position at the end of production. A physical contact zone not available for this reason, it is necessary to interfere with the embedded software in the electronic control unit (4) located in the socket (9). With the invention best software will be determined with a system developed for horn measuring various values. The system is sending with the physical connection terminal (3), which is positioned partly outside the socket (9) and partly inside the socket (9), the most appropriate software can be transferred to the electronic control unit (4). Physical connection terminal (3) nested on the outside, into the physical connection socket (9).
The most suitable software with a system will be determined developed for horn measuring various values with together invention. Physical connection terminal (3), partly positioned outside the socket (9) and partly inside the socket (9) is sending the best software electrical control unit (4) in this system. Physical connection terminal (3) nested in the outside over socket physical connection slot (8).
Over socket physical connection slot (8) consists of two protection walls (13). Said of protection walls (13) it is designed to eliminate the contact of the pins with each other during operation in order to fit the pin on which the physical connection terminal (3) is mounted, to protect the pin slot (12) from the physical effects that may come from the external environment and to be connected to the trunk (14). The horn will be made ready at the same time, the latest software is updated. Next a reservoir to ensure that the insulating filler material is applied in the correct position and amount to prevent software tampering again will be created.
