Vehicle navigation device and control system

Abstract

The invention relates to a vehicle navigation device and a control system. The vehicle navigation device comprises a main body and a mounting mechanism, and each mounting assembly comprises a mounting support, a connecting line and a mounting unit. The control system of the vehicle navigation device comprises a central control module and a working power supply module connected with the central control module. In the vehicle navigation device and the control system, angular deflection can be achieved between each mounting sleeve and a corresponding mounting block because first limiting teeth are engaged with second limiting teeth; accordingly, the main body can be mounted and fixed, and the practicability of the vehicle navigation device can be improved; in a working power supply circuit, isolation is performed through a transformer, the current is held through a second diode, wave filtering is performed through a fourth capacitor, and then constant voltage output is performed through a second integrated circuit; the power supply voltage is subjected to current holding and wave filtering through a first diode and a second capacitor correspondingly, and then constant voltage output is performed through a third integrated circuit; and therefore, two constant voltage output channels can be achieved and the practicability of the vehicle navigation device can be improved.

Description

technical field [0001] The invention relates to the field of vehicle navigation, in particular to a vehicle navigation device and a control system. Background technique [0002] Car navigation is carried out by using car GPS (Global Positioning System) and electronic map. It can tell the driver the shortest or fastest route to the destination conveniently and accurately, and is a good helper for the driver; [0003] In the existing car navigation, most of them need to go through cumbersome installation procedures during installation to ensure that the navigation equipment is installed in place, which greatly reduces the practicability of the equipment; not only that, inside the equipment, when it is running , because the output voltage of the internal working power supply circuit is unstable, and when performing multi-channel output, it needs to be provided by multiple power supply circuits, which not only reduces the stability of the working power supply circuit, but also i...
