Description

Technical Field

[0001] This utility model relates to the field of light rain sensor technology, and in particular to an irregularly shaped, small-sized, multifunctional light rain sensor. Background Technology

[0002] In the field of automotive intelligent technology, integrated light and rain sensor systems have become a core component for achieving adaptive control of vehicle environments. In existing solutions, these sensors typically integrate four basic functions: automatic wiper control, automatic headlight adjustment, ambient light monitoring, and adaptive brightness adjustment for the head-up display (HUD), often referred to as a four-in-one light and rain sensor. To address the issue of windshield fogging during driving in specific environments, an air conditioning defogging system has been added to the aforementioned four-in-one light and rain sensor, resulting in a five-in-one light and rain sensor. While this five-in-one integrated solution improves the defogging response accuracy of the air conditioning system through temperature and humidity data fusion compared to traditional four-in-one products, the additional sensing components for the air conditioning defogging system increase the product's longitudinal dimension by approximately 15 millimeters. When such light and rain sensors are installed inside the interior rearview mirror trim cover, they share limited installation space with other in-vehicle electronic devices such as cameras, millimeter-wave radar, and Electronic Toll Collection (ETC) systems. This intensifies the competition for space inside the trim cover and forces manufacturers to make a difficult trade-off between maintaining aesthetic appeal and expanding functionality.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0052] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0053] Example 1:

[0054] Embodiment 1 of this utility model provides an irregularly shaped, small-sized, multifunctional light and rain sensor, such as... Figure 1 and Figure 2 As shown, the system includes: a packaging assembly 1, a lens assembly 2, a circuit board 3, and an air conditioning defogger sensor assembly 4. The lens assembly 2 and the circuit board 3 are fixed inside the packaging assembly 1, and the air conditioning defogger sensor assembly 4 is sleeved on the outside of the packaging assembly 1. The packaging assembly 1 includes a mounting base 10, on which a plug-in portion 100 is provided. The air conditioning defogger sensor assembly 4 and the plug-in portion 100 are located on the same side of the mounting base 10, and the air conditioning defogger sensor assembly 4 is electrically connected to the circuit board 3. The circuit board 3 is provided with multiple light sensor units (not shown in the figure), and the lens assembly 2 is correspondingly arranged with the light sensor units.

[0055] By placing the air conditioning defogger sensor assembly 4 and the insertion part 100 of the mounting base 10 on the same side, and by adjusting the structure of the circuit board 3, the overall size of the light rain sensor is reduced. Compared with the existing structural design in which the insertion part 100 and the air conditioning defogger sensor assembly 4 are arranged longitudinally opposite each other, the structural design provided by this utility model can effectively reduce the space occupied by the light rain sensor, and does not require sacrificing the air conditioning defogger sensor assembly 4 to reduce the size of the light rain sensor, thereby providing more possibilities for the layout of other components inside the rearview mirror decorative cover.

[0056] To fully illustrate the optical rain sensor solution provided by this utility model, the structure provided in the above solution will be further described in detail below.

[0057] Encapsulation component 1, excluding mounting base 10, such as Figure 2 As shown, the encapsulation assembly 1 further includes a cover plate 11 and a silicone sheet 12. The mounting base 10 and the cover plate 11 are snapped together and fixed. The lens assembly 2 is mounted on one side of the mounting base 10, and the silicone sheet 12 covers the lens assembly 2 and is fixed to the mounting base 10. The circuit board 3 is disposed on the other side of the mounting base 10, located between the mounting base 10 and the cover plate 11. The specific method by which the mounting base 10 and the cover plate 11 are snapped together and fixed can be as follows: Figure 3 As shown, the mounting base 10 is provided with at least two first lock heads 101, such as... Figure 4 As shown, the cover plate 11 is provided with at least two first locking slots 110 corresponding to the first lock head 101, and the first lock head 101 and the first locking slots 110 are engaged and fixed.

[0058] As mentioned in the above scheme, the lens assembly 2 is mounted on the mounting base 10. In a preferred embodiment, such as... Figure 5 and Figure 6 As shown, the mounting base 10 is provided with a first mounting position 104 and a second mounting position 105. The lens assembly 2 includes an infrared lens 20 and a light beam lens 21. The infrared lens 20 is mounted at the first mounting position 104, and the light beam lens 21 is mounted at the second mounting position 105. Since multiple light sensor units are provided on the circuit board 3, ambient light needs to pass through the infrared lens 20 and the light beam lens 21 to enter the light sensor units. Therefore, as... Figure 7 , Figure 8 and Figure 9As shown, the infrared lens 20 includes a wiper lens section 200 and an air conditioning lens section 201. At the bottom of the first mounting position 104, a first through groove 1040 is provided at the corresponding positions of the wiper lens section 200 and the air conditioning lens section 201. The light lens 21 includes a HUD brightness adjustment section 210 and an automatic headlight section 211. At the bottom of the second mounting position 105, a second through groove 1050 is provided at the corresponding positions of the HUD brightness adjustment section 210 and the automatic headlight section 211. The first through groove 1040 and the second through groove 1050 are used to allow light to enter the light sensor unit on the circuit board 3.

[0059] Since circuit board 3 needs to be powered to communicate with the vehicle control system, and to ensure the stability of circuit board 3 during vehicle operation, such as... Figure 8 As shown, the mounting base 10 is provided with a fisheye terminal 106 and a positioning post 107. The fisheye terminal 106 is located near the insertion part 100 and is electrically connected to the insertion part 100. The fisheye terminal 106 and the positioning post 107 are located on opposite sides of the first mounting position 104 and the second mounting position 105. Figure 10a As shown, the circuit board 3 is provided with a metal hole 31 and a positioning hole 32. The fisheye terminal 106 is inserted into the metal hole 31, and the positioning post 107 is inserted into the positioning hole 32. The multiple fisheye terminals 106 and positioning posts 107 restrict the position of the circuit board 3 within the mounting base 10, preventing the circuit board 3 from shifting due to vibrations generated during vehicle operation.

[0060] For the five-in-one light and rain sensor, the newly added air conditioning defogging function needs to be built on the basis of the original circuit architecture. By connecting an external flexible printed circuit (FPC) with foldable characteristics, the temperature and humidity sensing chip of the air conditioning defogging system can be directly contacted with the inner surface of the glass, thereby establishing a real-time monitoring channel for the condensation parameters on the glass surface.

[0061] Therefore, as mentioned in the aforementioned scheme, the air conditioner defrosting sensor assembly 4 is sleeved on the outside of the encapsulation assembly 1. In one embodiment, the functional area of ​​the installation is divided according to the devices installed on the mounting base 10, such as... Figure 11As shown, the mounting base 10 includes a first mounting portion 102 and a second mounting portion 103, with the second mounting portion 103 located between the insertion portion 100 and the first mounting portion 102. The first mounting portion 102 is used to mount the lens assembly 2, and the second mounting portion 103 is used to mount the air conditioner defogger sensor assembly 4. In practical applications, the air conditioner defogger sensor assembly 4 needs to monitor the condensation parameters on the glass surface to determine whether the glass requires defogging. Therefore, as... Figure 12 As shown, the air conditioning defogger sensor assembly 4 includes a temperature and humidity measuring chip (not shown) and an FPC40. The temperature and humidity measuring chip is electrically connected to the FPC40, and the temperature and humidity measuring chip is in close contact with the inner surface of the window glass. The FPC40 is sleeved on the second mounting part 103.

[0062] To improve the reliability of the fixation between FPC40 and the second mounting part 103, such as Figure 11 and Figure 12 As shown, the FPC40 includes a fixing part 400, a chip mounting part 401, and an electrical connection part 402. The temperature and humidity measuring chip is disposed on the chip mounting part 401, as shown below. Figure 10a As shown, a gold finger 30 is provided on the circuit board 3, and the electrical connection part 402 is electrically connected to the gold finger 30; a second lock head 1030 is provided on one side of the second mounting part 103, and a second lock opening 4000 is provided on the fixing part 400, and the second lock opening 4000 is locked and fixed to the second lock head 1030. Figure 10b Designed for existing circuit board 3. Figure 10b The box indicates the location of the gold fingers. Except for the relatively different position of the gold fingers, the positions of the other components are basically the same as the shape of the circuit board 3 provided in this solution. Therefore, in the actual processing of the product, other core components and optical components on the circuit board 3 can remain stationary, so that the positions and structures of other corresponding external components can remain unchanged, further ensuring better portability of the new design.

[0063] Because FPC40 is relatively flexible, to prevent the second lock 4000 from detaching from the second lock head 1030, such as Figure 13 and Figure 14As shown, the cover plate 11 includes a first sealing portion 111 and a second sealing portion 112. The first sealing portion 111 is used to seal the area of ​​the mounting base 10 where the lens assembly 2 is located, and the second sealing portion 112 is used to seal the area of ​​the mounting base 10 where the air conditioning defogger sensor assembly 4 is located. Limiting plates 1120 are respectively provided on both sides of the second sealing portion 112. The limiting plates 1120 are respectively provided on both sides of the air conditioning defogger sensor assembly 4, and the limiting plates 1120 are used to prevent the air conditioning defogger sensor assembly 4 from falling off the mounting base 10. Figure 15 The diagram shows the limiting plate 1120 covering both sides of the air conditioner defogging sensor assembly 4.

[0064] During vehicle manufacturing, the light and rain sensor needs to be installed inside the decorative cover of the rearview mirror. Therefore, in order to allow the light and rain sensor to be installed on an external structure, such as... Figure 16 and Figure 17 As shown, the encapsulation assembly 1 further includes a spring coil 13, which includes two mounting arms 130 and a connecting arm 131. The two mounting arms 130 are respectively fixedly disposed at both ends of the connecting arm 131, and the connecting arm 131 is located in the middle of the mounting arm 130. Each end of the mounting arm 130 is provided with a snap-fit ​​interface 1300. At least two snap-fit ​​protrusions 1110 are provided on the outer surface of the first sealing portion 111, and the snap-fit ​​interfaces 1300 snap-fit ​​with the snap-fit ​​protrusions 1110 respectively. To increase the installation angle of the light-rain sensor to adapt to the limited space of the installation area, in a preferred embodiment, the number of snap-fit ​​protrusions 1110 can be four or more, thereby realizing more installation methods for the light-rain sensor. Specifically, since the spring coil 13 undergoes a certain deformation when the snap-fit ​​protrusion 1110 engages with the snap-fit ​​interface 1300, the mounting arm 130 and the connecting arm 131 are provided with interconnected I-beam grooves 1310. These I-beam grooves 1310 are used to ensure a tight fit between the snap-fit ​​protrusion 1110 and the snap-fit ​​interface 1300. Without the I-beam grooves 1310, the spring coil 13 would bend under the pressure of the two snap-fit ​​protrusions 1110, causing the snap-fit ​​protrusion 1110 to detach from the snap-fit ​​interface 1300. With the addition of the I-beam grooves 1310, when the snap-fit ​​protrusion 1110 presses against the snap-fit ​​interface 1300, the I-beam grooves 1310 contract inwards, thereby allowing the snap-fit ​​interface 1300 to exert a pushing force on the snap-fit ​​protrusion 1110, ensuring that the spring coil 13 is firmly fixed to the cover plate 11.

[0065] Secondly, to enable the optical rain sensor to be mounted on an external structure, spring plates 1311 are provided on both sides of the connecting arm 131. The spring plates 1311 are fixedly connected to the connecting arm 131, and there is a preset angle of inclination between the spring plates 1311 and the plane where the connecting arm 131 is located. The spring plates 1311 are used to realize the mounting of the optical rain sensor to the external structure. The preset angle can be 10° to 30°.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
