Problems solved by technology

The sunlight sensor is to adjust and control the working condition and output state of the automobile air conditioner in a timely manner by sensing the intensity of sunlight radiation. The existing sensors are not very sensitive to light, and cannot be well adjusted to light, and the reliability is not high.
[0003] The existing patent "2014103397268" discloses a multi-functional light sensor device with a warning light. Although there are two diodes of this light sensor, they are set on a T-shaped PCB, resulting in a large volume of the entire sensor. Not very practical when volume is required

Embodiment Construction

[0017] The invention discloses an automatic photosensitive sensor for vehicle temperature adjustment, such as figure 1 As shown, a base 1 is included, and a PCB board 2 and a housing 4 placed on the base are sequentially packaged. The housing 4 is provided with a terminal slot 11 , and the bottom of the PCB board is provided with a terminal 21 connected to the base 1 . The shell 4 is hemispherical, that is, the top is in a smooth transition, so as to better receive sunlight.

[0018] When the car is running, in order to better receive light, a photodiode 22 is correspondingly fixed on both sides of the PCB board. An included angle is set between the photosensitive surface of the photodiode 22 and the PCB 2 . The included angle between the photosensitive surface of the photodiode and the PCB board is 10°-90°. Since the sunlight in the morning is relatively peaceful, in order to receive light earlier, the angle between the photosensitive surface of the photosensitive diode an...

Abstract

The invention discloses an automatic photosensitive sensor for vehicle temperature adjustment, which includes a base, and sequentially encapsulates a PCB board and a casing placed on the base, a photosensitive diode is fixed on both sides of the PCB board, and the photosensitive surface of the photosensitive diode is There is an included angle with the PCB board. The outstanding effects of the invention are: the sunlight sensor can be sensitive to light as early as possible to better adjust the temperature, and the light diffusion effect is better by setting the atomized glue layer.

Description

technical field [0001] The invention relates to a sensor, in particular to an automatic photosensitive sensor for vehicle temperature regulation. Background technique [0002] Traditional automotive sunlight sensors are conducive to realizing an intelligent, humanized and comfortable environment in the car, reducing fuel consumption, saving energy, reducing use costs, and indirectly reducing vehicle exhaust emissions. It was originally used in the automatic air-conditioning system of high-end cars, but due to the popularity of cars, people have higher and higher requirements for the comfort and automation of cars, and now it has been popularized in middle and low-end cars. The sunlight sensor is to adjust and control the working condition and output state of the automobile air conditioner in a timely manner by sensing the intensity of sunlight radiation. The existing sensors are not very sensitive to light, and cannot be well adjusted to light, and the reliability is not hig...
