Vehicle navigation device based on Internet of things

Abstract

The invention discloses a vehicle navigation device based on the Internet of things. The device comprises a groove, an electric telescopic rod, an electric rotating seat, a bracket, a navigator main body, a rotating shaft, a first flat tooth, a spring, an end cover, a second flat tooth, a fixture block, a fixing hole, and a distance sensor, wherein the groove is internally provided with the electric telescopic rod, and the upper end of the electric telescopic rod is provided with the electric rotating seat. By setting a control circuit board and a navigation circuit board in the invention, since the heat dissipated by the control circuit board during working is less than that dissipated by the navigation circuit board during working, the control circuit board and the navigation circuit board are separated by a heat insulation board to prevent the working heat from superimposing that results in reducing the service life of the control circuit board. The circuit board with less heat dissipation is dissipated by a first heat-dissipating fin, and guide vanes are driven to rotate through motors in an air inlet pipeline and an air outlet pipeline to circulate the external airflow and theheat dissipated from the navigation circuit board so as to accelerate heat dissipation, thereby improving the heat dissipation efficiency by further cooperating with a second heat-dissipating fin anda third heat-dissipating fin.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a car navigation device based on the Internet of Things. Background technique [0002] Navigation device, the product of modern technology, is mostly used in cars for positioning and navigation. With the popularization of cars and the construction of roads, inter-city economic exchanges become more frequent. Vehicle-mounted GPS navigators are very important. Accurate positioning and navigation The all-in-one navigation can better meet the needs of car owners and become the basic equipment on the car. In the prior art, the navigation device is generally installed in the upper middle of the car center console, and it is a fixed installation. The angle of the display screen is in line with the driver's line of sight. Tilting, when the light is bright during the day, the display screen has reflections, which is not conducive to the driver's viewing. At the same time, it is exp...

[0002] Navigation device, the product of modern technology, is mostly used in cars for positioning and navigation. With the popularization of cars and the construction of roads, inter-city economic exchanges become more frequent. Vehicle-mounted GPS navigators are very important. Accurate positioning and navigation The all-in-one navigation can better meet the needs of car owners and become the basic equipment on the car. In the prior art, the navigation device is generally installed in the upper middle of the car center console, and it is a fixed installation. The angle of the display screen is in line with the driver's line of sight. Tilting, when the light is bright during the day, the display screen has reflections, which is not conducive to the driver's viewing. At the same time, it is exposed and the outside is easy to be contaminated with dust. In addition, the main body of the navigator is generally a circuit board structure. Due to the use of control functions and navigation functions When the internal components dissipate heat differently, the heat of the two is superimposed, which will easily cause the control circuit with less heat dissipation to have a shorter service life, and the circuit board needs to be replaced as a whole, and the overall heat dissipation effect is not good.
