Embodiment 1

[0048] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a vehicle information monitoring self-power supply system includes the steps of energy collection, power management and power supply to loads. In the energy harvesting step, an applicable type of energy harvesting device may be selected according to the characteristics of energy forms at different positions of the vehicle. The power management step is to combine and match modules according to the output performance of the energy harvesting device and the power consumption characteristics of the vehicle information monitoring load, so as to achieve the best power utilization efficiency and the best information monitoring effect. Vehicle information monitoring loads include but are not limited to GPS, four-wheel alignment, anti-theft alarm, anti-scratch sensor, tire wear degree, tire pressure monitoring, etc.

Embodiment 2

[0050] This embodiment provides a vibration energy collection device used in a vehicle information monitoring self-power supply system.

[0051] The vibration energy harvesting device mainly includes two parts, one part is the coil winding part, the other part is the magnetic field supply part, one part of the two parts is fixed with the energy harvesting device, and the other part can move in the energy harvesting device. The embodiment uses the coil winding part as the movable part, The magnetic field supply part is fixed with the energy harvesting device and cannot be moved.

[0052] Such as figure 2 , image 3 As shown, the coil winding part includes a conductive coil 10 and a third magnetically permeable material 20 , the third magnetically permeable material 20 is a soft magnetic material passing through the conductive coil 10 .

[0053] The magnetic field providing part comprises a first magnetic field providing part and a second magnetic field providing part, the fi...

Embodiment 3

[0057] This embodiment provides a tire deformation energy collection device used in a vehicle information monitoring self-power supply system.

[0058] The tire deformation energy collection device includes a movable part and a fixed part, a part of which is a coil winding, and a part is a magnetic field supply part, the movable part can move in the tire deformation energy collection device, and the fixed part remains relatively stationary with the tire deformation energy collection device.

[0059] Therefore, the tire deformation energy collection device can directly adopt the vibration energy collection device described in Embodiment 2, or can also adopt such as Figure 4, Figure 5 Apparatus form shown.

[0060] Wherein the coil winding 50 is a fixed part, and the magnetic field supply part is a movable part (the fixed part and the movable part can be exchanged).

[0061] The magnetic field supply part includes a fifth permanent magnet 60, a fourth magnetically permeable ...

Abstract

The invention provides a vehicle information monitoring self power supply system and belongs to the technical field of self power supply applied to motor vehicles. A method includes the energy acquisition step, the electric energy management step and the load power supply step. In the energy acquisition step, various modes of energy besides heat energy, solar energy, vibration energy, tire deformation and the like on a vehicle is acquired and converted into electric energy, the electric energy is continuously supplied to vehicle information monitoring loads, and therefore self power supply of a vehicle information monitoring system is achieved. Different types of energy acquisition devices are adopted according to the different energy modes supplied by the environments where the different loads are located. In the electric energy management step, the electric energy acquired by the energy acquisition devices is managed according to the output characteristics of the energy acquisition devices and the power use characteristics of the loads, so that the optimal electric energy use efficiency is obtained. The vehicle information monitoring self power supply system can be applied to real-time detection of the vehicle speed and the loads, automatic adjustment of the safe air pressure range of tire pressure monitoring equipment and auxiliary safe driving for tire puncturing prevention and tire puncturing accident prevention.

Description

technical field [0001] The invention relates to a vehicle information monitoring self-power supply system, which belongs to the technical field of self-power supply applied to motor vehicles. Background technique [0002] There are more and more sensor devices used for information monitoring on motor vehicles. The normal work of these sensors greatly guarantees the safety of driving. However, many front-mounted and rear-mounted sensors are inconvenient for pulling power, and even the location cannot be directly Pull wires are basically powered by batteries. It is very difficult and inconvenient to replace the battery of these battery-powered devices, and some even cannot replace the battery. The sensor becomes invalid as the battery is exhausted and can only be replaced with a new one; the bigger problem is that when the battery suddenly loses power and the sensor Sudden non-operation may result in the failure to detect dangerous situations in time and there is a risk of ac...
