The sunlight sensor is an indispensable part of future smart cars. It can sense the changes in light at any time to compensate and correct the car air conditioner, making vehicle driving more intelligent, humane and comfortable. At present, most sunlight sensors on the market are installed on the windshield of the car.

[0003] The dual-channel sunlight sensor mainly uses two left and right photodiodes to detect and sense infrared light and convert light energy into electrical signals to provide various electrical parameter data for the vehicle air conditioner. The traditional dual-channel sunlight sensor contains two left and right direct-insertion photodiodes (wavelength is about 880nm), a fixing seat, and a PCB board. When installing it, first install the photodiode chip in the fixing slot of the fixing seat with the direction facing up. During this process, the pins need to be bent so that they extend from the bottom of the fixing seat and insert into the PCB board, and finally the redundant pins are cut off. This requires secondary jacking of the pins and photodiodes, which is cumbersome and greatly increases labor costs and affects the consistency of the final product. Utility Model Content

[0031] See also Figure 1-5 As shown, according to the first aspect of the present application, an embodiment provides a patch-type integrated dual-channel sunlight sensor, including:

[0032] A card base 1, wherein fixing grooves 11 are provided on both sides of the card base 1 from the middle to both sides and tilted downward, and a buckle 12 is provided on the side wall of the card base 1 and located at the same tilt angle as the fixing groove 11, and the buckle 12 is at least partially located above the fixing groove 11, and an installation channel 13 is provided in the fixing groove 11;

[0033] The photosensitive element 2 includes a component body 21 and pins 22 connected thereto. The component body 21 is provided with extensions 211 on both sides. When the photosensitive element 2 is arranged in the fixing groove 11, the extensions 211 are engaged with the buckle 12, and the pins 22 are located in the installation channel 13.

[0034] Specifically, after placing the formed pin 22 into the installation channel 13 of the socket 1, the component body 21 can be installed in the fixing groove 11 by sliding and pressing the component body 21 downward. At this time, the buckle 12 is located above the edge 211 on both sides of the component body 21, so that the buckle 12 can be clamped to the component body 21. Compared with the traditional installation, the installation is more convenient and the installation efficiency is higher. The buckle 12 limits the component body 21, so that it is more tightly connected to the socket 1 after installation, the fixation is more firm, and the installation efficiency is higher.

[0035] The buckle 12 is at least partially located above the fixing groove 11 to achieve the limiting fixation of the extended edges 211 on both sides of the component body 21; the buckle 12 is installed above the side wall with the same inclination angle as the fixing groove 11 to achieve the limiting fixation of the installed component body 21.

[0036] Among them, the card seat 1 is a trapezoidal structure, and fixed grooves 11 are symmetrically opened on both sides thereof and gradually tilted downward from the middle. The tilt angle of the fixed groove 11 is determined according to the actual design, which can better simulate and perceive the light intensity; wherein the card seat 1 is made of plastic material and has a low cost.

[0037] Since each photosensitive element 2 includes two pins 22 , two penetrating installation channels 13 are provided on the fixing groove 11 to facilitate installation of the pins 22 .

[0038] Among them, the pin 22 is bent into shape before installation, and its bending size and position are adapted according to the size of the fixing groove 11 and the installation channel 13 of the card holder 1, so that it can be better fixed and installed with the card holder 1 after installation, and at the same time, it can better ensure the consistency of the two pins 22 after installation, thereby improving the accuracy of subsequent installation.

[0039] The number of the buckle 12 is at least one.

[0040] Specifically, the number of buckles 12 can be one or more, and the number installed is based on actual usage requirements.

[0041] The pin 22 includes: a first connecting section 221, a second connecting section 222 and a third connecting section 223;

[0042] The first end of the first connecting segment 221 is connected to the element body 21, the first end of the second connecting segment 222 is connected to the second end of the first connecting segment 221, the second end of the second connecting segment 222 extends vertically downward, the first end of the third connecting segment 223 is connected to the second end of the second connecting segment 222, and the second end of the third connecting segment 223 extends horizontally toward the middle of the card seat 1.

[0043] Specifically, the pin 22 is bent and formed before installation, and includes a first connecting segment 221, a second connecting segment 222 and a third connecting segment 223. The first connecting segment 221 is used to connect the first end of the second connecting segment 222 and the component body 21. The second connecting segment 222 is vertically arranged, and its second end is connected to the first end of the third connecting segment 223. The third connecting end is horizontally arranged. The bending angles of the first connecting segment 221, the second connecting segment 222 and the third connecting segment 223 are consistent with the fixing groove 11 and the installation channel 13 of the socket 1, so that after the component body 21 is installed in the fixing groove 11, it can be better fixed and installed with the socket 1, and at the same time, the consistency of the two pins 22 after installation can be better guaranteed.

[0044] Compared with the traditional method of soldering after the pin 22 is plugged into the PCB board, the third connecting section 223 in the present application is designed as a horizontal structure, so that the connection surface when the third section of the pin 22 is connected to the PCB board is larger, and the stability and reliability after soldering can be improved.

[0045] The third connecting section 223 is located below the bottom of the card holder 1 .

[0046] Specifically, the lower wall surface of the third connecting section 223 is located below the bottom of the card holder 1, which facilitates the connection between the third connecting section 223 of the pin 22 and the PCB board, making installation more convenient.

[0047] A positioning groove 14 is formed on a side wall of the installation channel 13 away from the middle of the holder 1 . When the component body 21 is located in the fixing groove 11 , the second connecting section 222 is disposed in the positioning groove 14 .

[0048] Specifically, the positioning groove 14 is located on the side of the positioning channel 13 of the card holder 1 away from the middle part of the card holder 1. The structure of the positioning groove 14 is adapted to the structure of the second connecting section 222 of the pin 22. When the component body 21 is installed in the fixing groove 11, the second connecting section 222 is located in the positioning groove 14. Through the setting of the positioning groove 14, the pin 22 can be limited, the stability of the pin 22 can be improved, and the subsequent welding operation of the pin 22 and the PCB board is convenient.

[0049] The length of the installation channel 13 is greater than the length of the third connecting section 223 .

[0050] Specifically, the length of the installation channel 13 is greater than the length of the third connecting section 223. Through such a setting, the pin 22 can be placed in the installation channel 13 before the component body 21 is installed, providing sufficient placement space for the pin 22 when the component body 21 is installed in the fixing groove 11, thereby facilitating the subsequent installation operation of the component body 21.

[0051] The width of the installation channel 13 is also greater than the width of the third connecting section 223 .

[0052] It also includes a PCB board, and the PCB board is connected to the third connecting section 223.

[0053] The PCB board and the third connecting section 223 are connected by welding.

[0054] Specifically, through the setting of the PCB board, the circuit on the PCB board can receive electrical signals from the sunlight sensor element, which are related to the intensity, wavelength and other characteristics of the sunlight, and can process and convert the collected original signals, such as amplification, filtering, analog-to-digital conversion, etc., to convert them into usable digital or analog signals. The processed signals are transmitted to related control systems or devices, such as the vehicle's automatic headlight system, so that the system can respond accordingly according to the sunlight conditions.

[0055] The element body 21 includes a photosensitive chip inside, and the photosensitive chip is a PD light receiving chip with full spectrum sensing.

[0056] Specifically, by setting up the photosensitive chip as a PD light receiving chip with full-spectrum sensing, it can sensitively and effectively sense light while providing electrical signals for the vehicle air conditioner. At the same time, the vehicle control system will compensate according to the differences in the electrical signals on the left and right.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
