Vehicular multimedia player with electromagnetic inductive switch

Abstract

The multimedia player includes main body of player. Electromagnetic induction switch of the main body of player is linked to taximeter. Through signal lone, the said switch installed on taximeter is connected to the multimedia player in order to controlling stopping or playing the player. The electromagnetic induction switch includes a magnet and a switch box. Electromagnetic induction element is installed inside the switch box; and dry reed tube is as optimal element. The magnet is fixed on lamp of showing no passenger on taxi; and switch box is fixed on place near to the location when the said lamp lays down. Features are: compact structure, light weight, long service life and reliable contact.

Description

technical field [0001] The invention relates to a vehicle multimedia player, in particular to a vehicle multimedia player with an electromagnetic induction switch. Background technique [0002] With the development of the economy, the pace of people's life and work is accelerating, and more and more people take taxis when going out. Therefore, the advertising media industry has correspondingly launched car multimedia players for taxis, such as car DVDs. Multimedia players, etc. Media operators install such players on taxis to provide advertising services to their advertisers in order to obtain advertising revenue. While passengers are taking taxis, they provide multimedia entertainment services and broadcast advertising information at the same time. , to provide advertising and publicity services, allowing passengers to sneak in to enjoy entertainment programs while receiving advertising information unknowingly, so as to achieve better advertising effects.

Problems solved by technology

[0003] However, there are currently many brands of taxi meters with different electrical characteristics, and they are all mechanical push-type switches. Some of them rely on hand to press down the empty car light to give a signal to the meter to start the meter, and some rely on pressing The switch on the taximeter starts the taximeter and at the same time gives the signal to the empty car light to turn down the empty car light. Some are level signals, and some are pulse signals. It is very difficult to allow different odometers to give the same electrical signal to control the player, which is not universal and is not conducive to the installation, use and maintenance of the car multimedia player, so it has caused great damage to the promotion of the car multimedia player. big obstacle

[0004] The empty car light is an electromechanical device. If you want the empty car light to mechanically press a switch to give a signal, there are problems: 1. At present, there is no switch with such a large stroke. Even if there is, the switch will be damaged soon after frequent use. Normal playback; 2. The car will be bumpy when driving, and the empty car lights may cause misoperation of the switch, causing the player to switch on and off repeatedly, which has poor reliability and affects the service life of the whole machine
