Embodiment Construction

[0023] A vehicle-mounted voice safety reminder device in a preferred embodiment of the present invention has a structure such as figure 1 As shown, it is electrically connected to the output of the vehicle power supply by plugging and unplugging the USB plug, including the main control module U1 and the speaker SP electrically connected thereto. The voltage detection terminal of the main control module U1 is electrically connected to the positive output terminal of the vehicle power supply. The power supply terminal of the main control module U1 is electrically connected to the positive output terminal of the vehicle power supply through the first diode D1, and at the same time is electrically connected to the positive output terminal of the storage battery JP1 through the second diode D2. The first diode D1 The cathode of the second diode D2 and the cathode of the second diode D2 are electrically connected to the power supply terminal; the battery JP1 is also electrically conn...

Abstract

The invention relates to an on-board voice safety reminder, which is movably and electrically connected with an automobile power output in a plug-in manner. The on-board voice safety reminder comprises a main control module (U1) and a voice output unit electrically connected therewith; the voltage detection end of the main control module is electrically connected with the positive output end of an automobile power; the main control module and the power end of the voice output unit are electrically connected with the positive output end of the automobile power through a first diode (D1), and are electrically connected with the positive output end of a battery through a second diode (D2); both the negative electrode of the first diode and the negative electrode of the second diode are electrically connected with the power end. The safety reminder works according to the following manner: when detecting that the power end changes from low level to high level, the main control module outputs a voice prompt for driving; when detecting that the power end changes from high level to low level, the main control module controls the voice output unit to output a voice prompt for stopping. The on-board voice safety reminder can be widely applied to various on-board electronic appliances, and can increase safety and user comfort level.

Description

technical field [0001] The invention relates to electronics, software and vehicle-mounted auxiliary electrical appliances, in particular to a vehicle-mounted voice safety reminder device. Background technique [0002] The 5V / 12V DC power supply in the car is an interface that provides power to electrical appliances outside the vehicle. Its output voltage is 5V / 12V, and the current varies with different models. The power supply in the car can be externally connected to various electrical equipment such as car phones, portable DVDs, mobile phone chargers, etc., which is more convenient to use. However, the current on-board electrical products on the market can only achieve the same functions as those not used in the car, and cannot meet the special requirements of on-board use. Contents of the invention [0003] The technical problem to be solved in the present invention is how to provide a vehicle-mounted voice safety reminder device, which can intelligently provide corres...
