Automotive power supply delay switch device and control method thereof

Abstract

The invention relates to an automotive power supply delay switch device and a control method thereof. When a storage battery outputs voltage stably and the environment temperature in an automobile returns to normal after the automobile is started, vehicle-mounted electric appliances are supplied with power. The technical scheme is that the automotive power supply delay comprises an input end, an output end, a power supply module, a microprocessor, an interaction module and an on-off module, wherein the input end is respectively connected with the on-off module and the power supply module; the power supply module and the interaction module are respectively connected with the microprocessor; the microprocessor is also connected with the on-off module; the on-off module is also connected with the output end; the power supply module supplies power to the microprocessor; the interaction module receives a delay signal and a delay time signal sent by a user; and after the on-off module receives the power supply instruction from the microprocessor, the on-off module is closed, and the output end supplies power to the vehicle-mounted electric appliances. The automotive power supply delay and the control method have the beneficial effects of protecting the vehicle-mounted electric appliances, saving power consumed by the automotive storage battery, being simple and practical and low in cost, and being suitable for vehicles.

Description

Technical field [0001] The invention relates to a power delay switch device for a vehicle and a control method thereof. Background technique [0002] With the development of on-board electrical appliances, more and more vehicles are equipped with on-board electrical appliances such as digital television receivers. In particular, buses and buses are generally equipped with on-board digital television receivers to facilitate passengers to watch TV programs in real time. However, due to the different conditions of the vehicle, the output voltage is unstable when the engine is ignited, which will cause the on-board electrical appliances to not work normally. For example, when a vehicle with a gasoline engine with a 12V battery is ignited, the output voltage of the car battery is very unstable. It will drop drastically, even lower than 6.5V, so it is easy to cause the on-board electrical appliances to fail or even damage during ignition. In addition, because the vehicle is generally ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a vehicle power delay switch device and its control method in view of the current problems that the output voltage is unstable when the vehicle is ignited or the temperature in the vehicle is too low to affect the normal start-up of the vehicle electrical appliances , so that the output voltage of the battery is stable after the car is started and the ambient temperature in the car returns to normal, and then power is supplied to the car electrical appliances
