Description

Technical Field

[0001] This application relates to the field of transportation technology, and more particularly to a bracket, a sensing device, and a transportation vehicle. Background Technology

[0002] Advanced Driver Assistance Systems (ADS) sensors such as cameras and lidar are crucial components of autonomous vehicle technology. ADS cameras acquire real-time image information through lenses and image sensors to monitor the vehicle's external environment and assist the driver in safe driving. LiDAR obtains three-dimensional information about objects around the vehicle by emitting laser beams and measuring reflection time. ADS cameras and lidar are typically mounted on the inner side of the windshield using brackets, creating a field of view (FOV) area between them and the windshield.

[0003] Currently, in cars on the market, high-temperature and high-humidity gases can easily enter the FOV (Field of View) area. When these gases come into contact with the windshield, they cause frost and fogging within the FOV area, affecting the detection of the surrounding environment by cameras and lidar. Utility Model Content

[0004] This application provides a bracket that, when used to mount a sensor on the windshield of a vehicle, reduces the entry of high-temperature, high-humidity gases into the sensor's field of view (FOV), thereby lowering the risk of frost and fogging in the FOV area. This application also provides a sensing device including the bracket and a vehicle; the sensing device exhibits better accuracy, and the vehicle demonstrates superior performance.

[0005] In a first aspect, embodiments of this application provide a bracket. The bracket is applied in a sensing device of a vehicle. The bracket includes a bracket body, a first sealing ring, and an adhesive component; the bracket body includes a plate and a groove, the plate includes a first surface and a second surface disposed opposite to each other, the groove is recessed relative to the first surface to form a receiving groove, the receiving groove forming an opening on the first surface; the first sealing ring and the adhesive component are both fixedly connected to the first surface, and the first sealing ring surrounds the opening; the first surface is used to fix a windshield to the windshield via the adhesive component, and to seal the windshield via the first sealing ring.

[0006] In this embodiment, the bracket can be installed on the windshield via adhesive. When the bracket is installed on the windshield, the connection to the windshield can be sealed by the first sealing ring, thereby reducing the risk of high-temperature and high-humidity gases entering the receiving groove through the opening, and thus reducing the risk of frost and fogging inside the receiving groove. When the bracket is applied to the sensing device of a vehicle, it can reduce the risk of insufficient sensing accuracy of the sensors (including cameras and / or lidar).

[0007] In some possible implementations, the first sealing ring is located on the side of the adhesive near the opening.

[0008] It is understood that in this embodiment, the first sealing ring can be located inside the adhesive. Compared with the scheme where the first sealing ring is located on the side of the adhesive that is away from the opening of the receiving groove, in this embodiment, when the bracket is installed on the windshield through the adhesive, the bracket and the windshield can achieve a better interference fit with the first sealing ring under the action of the adhesive, thereby improving the sealing effect of the first sealing ring.

[0009] In this embodiment, by setting the adhesive part to surround the opening of the receiving groove, the connection between the bracket and the windshield can be strengthened on the one hand; on the other hand, the adhesive part can partially surround the first sealing ring, or the first sealing ring can surround the adhesive part. Thus, when the bracket is installed on the windshield through the adhesive part, the first sealing ring can better seal the opening of the receiving groove under the action of the adhesive part, which is beneficial to improving the sealing effect of the first sealing ring.

[0010] In some possible implementations, the adhesive surrounds the opening. It is understood that the adhesive can surround the opening of the receiving groove. For example, the adhesive can be annular. This improves the connection strength between the bracket and the windshield; it also allows the adhesive to surround the first sealing ring, or the first sealing ring to surround the adhesive, so that when the bracket is installed on the windshield via the adhesive, the first sealing ring can better seal the opening of the receiving groove under the action of the adhesive, thus improving the sealing effect of the first sealing ring.

[0011] In some possible implementations, the adhesive portion surrounds the opening. It is understood that the adhesive portion may be located around the opening of the receiving groove, but not completely surround it. In this embodiment, by providing an adhesive portion that partially surrounds the opening of the receiving groove, the connection strength between the bracket and the windshield can be improved. Furthermore, this allows the adhesive portion to partially surround the first sealing ring, or the first sealing ring to surround the adhesive portion. Therefore, when the bracket is installed on the windshield via the adhesive portion, the first sealing ring can better seal the opening of the receiving groove under the action of the adhesive portion, thus improving the sealing effect of the first sealing ring.

[0012] In some possible implementations, the adhesive component includes multiple adhesive portions spaced apart. It is understood that the adhesive portions surround or partially surround the opening of the receiving groove. In this embodiment, the adhesive portions can be positioned at multiple locations on the plate as needed, and the number of adhesive portions can vary at different locations. The arrangement of the adhesive portions is flexible and can meet the different connection needs between the bracket and different windshields, making it widely applicable.

[0013] In some possible implementations, the bracket further includes an adhesive layer, through which the first sealing ring is fixedly connected to the first surface. In this embodiment, the first sealing ring is connected to the plate by adhesive bonding, which simplifies the assembly process of the bracket body.

[0014] In some possible implementations, the bracket body and the first sealing ring are integrally molded components. For example, the bracket body and the first sealing ring can be integrally molded by two-color injection molding, which simplifies the manufacturing process of the bracket and makes it less likely for the first sealing ring to detach from the bracket body.

[0015] In some possible implementations, the plate body has a first snap-fit ​​portion, and the first sealing ring has a second snap-fit ​​portion, with the first and second snap-fit ​​portions snapping together. In this embodiment, the first sealing ring can be connected to the bracket body by a snap-fit ​​mechanism, and the snap-fit ​​portion facilitates the positioning and assembly of the first sealing ring and the bracket body.

[0016] In some possible implementations, the first sealing ring is welded to the plate. For example, the first sealing ring can be fixedly connected to the plate by fusion welding, thereby improving the connection strength between the first sealing ring and the plate.

[0017] In some possible implementations, the material of the first sealing ring includes at least one of PU, TPE, and EPDM. Of course, the first sealing ring can also be other soft materials that can perform a sealing function.

[0018] In some possible implementations, the tank is provided with vent holes that connect to the receiving tank; the support also includes a filter element that is fixedly connected to the tank and covers the vent holes, and the filter element is used for waterproofing and ventilation.

[0019] In this embodiment, the filter element allows air to enter and exit the receiving tank through vents to balance the air pressure within the tank. Simultaneously, the filter element absorbs moisture generated within the receiving tank, reducing the moisture content of the air entering the tank and thus lowering the humidity level, thereby reducing the risk of frost or fogging within the tank. The vents can be continuous through-holes or honeycomb pores.

[0020] In some possible implementations, the filter element includes a desiccant. It is understood that the filter element can be a drying box, and the desiccant can be fixedly connected to the tank through a housing. Using a desiccant as the filter element helps reduce costs. Of course, the filter element can also be other waterproof and breathable structural components.

[0021] In some possible implementations, the filter element includes a waterproof and breathable membrane. Using a waterproof and breathable membrane as the filter element can better prevent moisture from entering the containment tank and provides better anti-fogging effects. Of course, the filter element can also be other waterproof and breathable structural components.

[0022] In some possible implementations, the tank includes a bottom wall and a side wall, the side wall is fixedly connected to the plate, the bottom wall is located on the side of the side wall away from the plate and is fixedly connected to the side wall; the side wall is provided with a mounting hole for mounting a sensor; the bracket also includes a second sealing ring, which is provided in the mounting hole for sealing the hole wall of the mounting hole and the sensor.

[0023] Understandably, the sensor can be installed on the side wall of the tank, creating a field of view (FOV) between it and the windshield. In this embodiment, by providing a second sealing ring, high-temperature and high-humidity external gases can be prevented from entering the receiving tank through the mounting hole, thereby reducing the risk of frost and fogging inside the receiving tank, and consequently reducing the risk of frost and fogging in the sensor's FOV area.

[0024] In some possible implementations, the groove sidewall includes a first side portion with a mounting hole; a plate surrounds the receiving groove and includes a first portion connected to the first side portion; a first sealing ring has a notch located in the first portion.

[0025] In this embodiment, the sensor is mounted on the first side of the tank, and the notch of the first sealing ring can be close to the first side of the tank, that is, the first sealing ring can be close to the sensor, for the purpose of heat dissipation of the sensor. This reduces the risk of frost or fogging caused by the high-temperature, high-humidity gas generated by the sensor coming into contact with the windshield. In some examples, the notch of the first sealing ring can be a continuous opening, in which case the first sealing ring can be open-ring shaped. In other examples, the notch of the first sealing ring can also be a honeycomb structure, that is, the notch includes multiple spaced through holes. It is understood that the notch of the first sealing ring can also take other forms to achieve heat dissipation of the sensor.

[0026] In some possible implementations, the tank includes a bottom wall and a side wall, the side wall being fixedly connected to a plate, the bottom wall being located on the side of the side wall away from the plate and fixedly connected to the side wall; the support also includes a heating element, which is fixedly connected to the bottom wall and / or the side wall, and is used to generate heat when energized.

[0027] In this embodiment, the heating element raises the temperature inside the receiving tank, disrupting the thermal balance within the tank and thus reducing fogging or accelerating fog removal. Furthermore, by placing the heating element on the tank body, such as on the side wall of the tank, the FOV area of ​​the sensor can be avoided, thereby preventing the heating element from affecting the optical imaging effect of the sensor (including cameras and / or lidar), such as edge diffraction and image shadowing issues.

[0028] In some possible implementations, the tank body is provided with a vent hole that connects to the receiving tank; the heating element covers the vent hole and is provided with a vent hole that connects to the vent hole. In this implementation, the heating element allows air to enter and exit the receiving tank through the vent hole to balance the air pressure within the receiving tank.

[0029] In some possible implementations, the support also includes a drying element fixedly connected to the tank; the orthographic projection of the heating element on the tank at least partially covers the orthographic projection of the drying element on the tank. It is understood that the orthographic projection of the heating element on the tank can completely cover the orthographic projection of the drying element on the tank, or it can partially cover the orthographic projection of the drying element on the tank. The temperature around the heating element rises when it generates heat. In this embodiment, the drying element can be used to absorb water vapor generated around the heating element due to the increased temperature.

[0030] In some possible implementations, the outer surface of the heating element includes an exposed area that protrudes into the receiving groove, and the exposed area is provided with a matte finish.

[0031] This embodiment, by providing an anti-glare structure in the exposed area of ​​the heating element, can prevent the exposed area of ​​the heating element from reflecting light under sunlight or lamplight, thus affecting the optical imaging effect of the sensor.

[0032] In some possible implementations, the heating element includes at least one of a metal wire, a metal sheet, a metal film, a printed line, a graphene heating element, and a graphene coating. This results in a simple structure for the heating element, which can generate heat when energized, and its heating method is straightforward.

[0033] In some possible implementations, the support also includes an insulation element that is fixedly connected to the heating element or the tank, and the insulation element is located on the side of the heating element away from the receiving tank.

[0034] In this embodiment, the insulation component can be used to maintain the temperature of the heating element after the heating element is powered off, so that more heat can be transferred to the receiving tank, thereby ensuring the defogging efficiency. For example, the material of the insulation component may include at least one of sponge, foam, and aluminum foil.

[0035] In some possible implementations, the bracket further includes a first temperature sensor, a second temperature sensor, and a humidity sensor, all disposed in a receiving groove. The first temperature sensor is used to detect the temperature inside the receiving groove, the humidity sensor is used to detect the humidity inside the receiving groove, and the second temperature sensor is used to detect the temperature of the inner surface of the windshield. Alternatively, the bracket may further include a temperature and humidity sensor disposed in the receiving groove, which is used to detect the temperature inside the receiving groove, the humidity inside the receiving groove, and the temperature of the inner surface of the windshield.

[0036] In this embodiment, the bracket can calculate the dew point (Td) by detecting the temperature and humidity inside the receiving tank. Combined with the dew point (Td), the allowable temperature (Ta) can be calculated, where the allowable temperature Ta = Td + Δ1 (Δ1 is an offset value that can be calibrated according to actual conditions). By comparing the temperature of the inner surface of the windshield with the allowable temperature, it is possible to control whether the heating element needs to be energized to reduce fogging or defogging.

[0037] In some possible implementations, the bracket also includes a heating element and a processor. The heating element is fixedly connected to the groove and is used to generate heat when energized. The processor is electrically connected to the heating element and a first temperature sensor, a second temperature sensor, and a humidity sensor. The processor is used to control whether the heating element is energized based on the detection values ​​of the first temperature sensor, the second temperature sensor, and the humidity sensor.

[0038] In this embodiment, a first temperature sensor detects the temperature inside the cavity and transmits this first temperature information to the processor. A humidity sensor detects the humidity inside the cavity and transmits this humidity information to the processor. A second temperature sensor detects the temperature inside the cavity and transmits this second temperature information to the processor. The processor calculates the dew point (Td) based on the first temperature and humidity information, and determines the allowable temperature (Ta) based on the dew point (Td). The processor compares the temperature of the inner surface of the windshield with the allowable temperature (Ta) based on the second temperature information. If the temperature of the inner surface of the windshield is lower than the allowable temperature (Ta), the processor controls the heating element to be energized to raise the temperature of the inner surface of the windshield, thereby achieving defogging. If the temperature of the inner surface of the windshield rises to a safe temperature (Ts), where the safe temperature Ts = Ta + Δ2 (Δ2 is a bias value that can be calibrated according to actual conditions), the processor controls the heating element to stop being energized.

[0039] In some possible implementations, the bracket also includes a heating element and a processor. The heating element is fixedly connected to the groove and is used to generate heat when energized. The bracket also includes a processor that is electrically connected to the heating element and a temperature and humidity sensor. The processor is used to control whether the heating element is energized based on the detection value of the temperature and humidity sensor.

[0040] Secondly, embodiments of this application also provide a sensing device. The sensing device includes a sensor and the aforementioned bracket. The sensor is mounted on the bracket body and is at least partially exposed relative to the receiving groove. Fogging is less likely to occur within the FOV area of ​​the sensing device, resulting in better optical imaging performance.

[0041] In some possible implementations, the sensors include cameras and / or lidar. Cameras and / or lidar can be used to acquire real-time environmental information about the vehicle's surroundings to monitor the external environment and assist the driver in safe driving. Specifically, cameras can acquire image information in real time through a lens and image sensor. LiDAR can acquire three-dimensional information about objects around the vehicle by emitting a laser beam and measuring the reflection time.

[0042] Thirdly, embodiments of this application also provide a vehicle. The vehicle includes a windshield and the aforementioned sensing device, with a first surface facing the inner side of the windshield, an adhesive component fixedly connected to the inner side of the windshield, and a first sealing ring sealingly connected to the inner side of the windshield. The vehicle has high accuracy and superior performance in sensing the surrounding environment. Attached Figure Description

[0064] The embodiments of this application are described below with reference to the accompanying drawings.

[0065] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", etc. should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0066] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0067] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0068] References or "some embodiments" as described in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiments, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0069] The terms “including,” “having,” and their variations all mean “including but not limited to,” unless otherwise specifically emphasized. The term “multiple” means at least two.

[0070] It is understood that the specific embodiments described herein are merely illustrative of related embodiments and not intended to limit the scope of those embodiments. Furthermore, it should be noted that, for ease of description, only the parts relevant to the embodiments are shown in the accompanying drawings.

[0071] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0072] As people's demands for convenience, intelligence, and safety in transportation (such as vehicles, ships, and airplanes) continue to increase, more and more in-vehicle devices are being integrated into these vehicles. These in-vehicle devices include, but are not limited to, sensors, projection devices, in-vehicle refrigerators, audio devices, ambient lighting devices, electronic instrument panels, and central control screens.

[0073] The following example uses vehicles as the means of transportation and sensors as the onboard equipment. First, let's combine... Figure 1A and Figure 1B Examples of some application scenarios for vehicle-mounted equipment are provided.

[0074] Please refer to the following: Figure 1A and Figure 1B , Figure 1A This illustration shows an application scenario of a sensing device 20 provided in this application in the field of transportation. Figure 1B This illustration shows another perspective on the application scenario of a sensing device 20 provided in this application within the field of transportation. It is understood that... Figure 1A and Figure 1B The diagram only schematically illustrates some of the components included in the vehicle 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 1A and Figure 1B Limited by.

[0075] Depend on Figure 1A and Figure 1B As can be seen, the vehicle 100 may include a windshield 10. The windshield 10 may be the front windshield, rear windshield, or other windshield glass of the vehicle 100. This application embodiment uses a front windshield 10 as an example for explanation. The front windshield 10 is usually installed at the front of the vehicle, and its main function is to block the wind and light from the front.

[0076] The sensor 20 is mounted on the windshield 10, and a field of view (FOV) exists between the sensor 20 and the windshield 10. The sensor 20 can acquire real-time environmental information about the vehicle's surroundings through the FOV area to monitor the external environment and assist the driver in safe driving. During vehicle operation, the sensor 1 of the sensor 20 acquires road information ahead, including distance to the vehicle ahead, vehicle speed, and road conditions. This digital information is then displayed as an image on the in-vehicle screen (e.g., the central control screen), allowing the driver to better understand the vehicle's external environment and promoting safer driving.

[0077] As described in the background section, frost or fogging in the FOV area of ​​a sensing device can affect its functionality. Therefore, this application provides a bracket, a sensing device, and a vehicle that can reduce the risk of frost or fogging in the FOV area of ​​the sensing device. It should be understood that the embodiments in this application are described using a sensing device as an example; this application is equally applicable to cases where the bracket is used for other vehicle-mounted equipment.

[0078] The bracket, sensing device, and vehicle provided in this application will now be described with reference to the accompanying drawings. The bracket can be used in the sensing device of a vehicle.

[0079] Please refer to the following: Figures 2A to 3 , Figure 2A This is a schematic diagram of the structure of the sensing device 20 provided in some embodiments of this application. Figure 2B yes Figure 2A The schematic diagram shown is a partial structural diagram of the sensing device 20 in some embodiments. Figure 3 yes Figure 1B The diagram shows a partial structural view of the vehicle 100 cut along point AA in some embodiments.

[0080] In some embodiments, the sensing device 20 includes a sensor 1 and a bracket 2. The sensor 1 can be mounted on the inner surface 101 of the windshield 10 via the bracket 2. The inner surface 101 of the windshield 10 is the side surface of the windshield 10 closest to the interior of the vehicle 100. For example, Figure 2B yes Figure 2A The diagram shows the structure of bracket 2. Figure 3 Includes Figure 2B The bracket shown is 2.

[0081] For example, the bracket 2 includes a bracket body 21, a first sealing ring 22, and an adhesive member 23. The bracket body 21 includes a plate 211 and a groove 212. The plate 211 includes a first surface 2111 and a second surface 2112 facing away from each other. The groove 212 is recessed relative to the first surface 2111 of the bracket body 21 to form a receiving groove 213. The receiving groove 213 forms an opening 214 on the first surface 2111 of the bracket body 21. For example, Figure 3 The plate 211 and the groove 212 are schematically divided by dashed lines. The plate 211 can surround and accommodate the groove 213.

[0082] Understandably, in some examples, plate 211 and groove 212 can be two separate structural components, and plate 211 and groove 212 can be connected together by means of bonding, welding, snap-fit ​​connection, screw connection, etc. In other examples, the bracket body 21 can also be a one-piece structural component. In this application, "one-piece molding" means that two components are obtained through a one-piece molding process, in which the component is connected to the other component during the formation of one of the two components, without the need for further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two components together. For example, plate 211 and groove 212 of bracket body 21 can be integrally molded by injection molding, or bracket body 21 can be a sheet metal part, in which case plate 211 and groove 212 of bracket body 21 can be formed by stamping.

[0083] In some embodiments, the first sealing ring 22 and the adhesive 23 are both fixedly connected to the first surface 2111 of the plate 211. The first sealing ring 22 surrounds the opening 214 of the receiving groove 213. The first surface 2111 of the plate 211 is fixedly connected to the windshield 10 by the adhesive 23, at which time the first surface 2111 of the plate 211 faces the windshield 10. The first surface 2111 of the plate 211 is also sealed to the windshield 10 by the first sealing ring 22. It is understood that a sealed connection means that when two or more components are connected, the gap between the components can be sealed, so that gas cannot pass through the gap between the components. In the embodiments of this application, the first sealing ring 22 is interference-fitted with the bracket body 21 and with the windshield 10.

[0084] For example, the first surface 2111 of the plate 211 can be fixedly connected to the inner surface 101 of the windshield 10. The first sealing ring 22 and the adhesive 23 are both located between the first surface of the plate 211 and the inner surface 101 of the windshield 10. The first sealing ring 22 can seal the connection between the first surface of the plate 211 and the inner surface 101 of the windshield 10, and the adhesive 23 can fix the connection between the first surface of the plate 211 and the inner surface 101 of the windshield 10.

[0085] In this embodiment, the bracket 2 can be installed on the windshield 10 via the adhesive 23. When the bracket 2 is installed on the windshield 10, it can be sealed to the windshield 10 by the first sealing ring 22, thereby reducing the risk of high-temperature and high-humidity gas entering the receiving groove 213 through the opening 214. This reduces the risk of frost or fogging in the receiving groove 213, and consequently reduces the risk of insufficient sensing accuracy of the sensor 1. In this way, fogging is less likely to occur in the FOV area of ​​the sensing device 20, resulting in better optical imaging of the sensing device 20 and higher accuracy and performance of the vehicle in sensing the surrounding environment.

[0086] Furthermore, in this embodiment, the adhesive 23 and the first sealing ring 22 are two separate structural components. If the adhesive 23 fails, the first sealing ring 22 can still have a sealing effect and can better seal the gap between the bracket 2 and the windshield 10, so that high temperature and high humidity gas is not easy to enter the receiving groove 213 through the gap between the bracket 2 and the windshield 10.

[0087] Please continue reading. Figures 2A to 3 In some embodiments, the first sealing ring 22 may be located on the side of the adhesive member 23 near the opening 214 of the receiving groove 213. It is understood that in this embodiment, the first sealing ring 22 may be located inside the adhesive member 23. Compared to the option where the first sealing ring is located on the side of the adhesive member away from the opening of the receiving groove, in this embodiment, when the bracket 2 is installed on the windshield 10 via the adhesive member 23, the bracket 2 and the windshield 10 can achieve a better interference fit with the first sealing ring 22 under the action of the adhesive member 23, thereby improving the sealing effect of the first sealing ring 22. In other embodiments, at least a portion of the first sealing ring 22 may also be located on the side of the adhesive member 23 away from the opening 214 of the receiving groove 213. This application does not strictly limit the relative position of the first sealing ring 22 and the adhesive member 23.

[0088] In some embodiments, the adhesive 23 may partially surround the opening 214 of the receiving groove 213. It is understood that the adhesive 23 may be located around the opening 214 of the receiving groove 213, but not completely surround it. In this embodiment, by setting the adhesive 23 to partially surround the opening 214 of the receiving groove 213, the connection between the bracket 2 and the windshield 10 can be strengthened. Furthermore, the adhesive 23 can partially surround the first sealing ring 22, or the first sealing ring 22 can surround the adhesive 23. Therefore, when the bracket 2 is installed on the windshield 10 via the adhesive 23, the first sealing ring 22 can better seal the opening 214 of the receiving groove 213 under the action of the adhesive 23, which is beneficial to improving the sealing effect of the first sealing ring 22.

[0089] For example, the adhesive component 23 may include a plurality of adhesive portions 23a, which are spaced apart. It is understood that the plurality of adhesive portions 23a surround or partially surround the opening 214 of the receiving groove 213. In this embodiment, the adhesive portions 23a can be set at multiple locations on the plate 211 as needed, and the number of adhesive portions 23a at different locations can be different. The arrangement of the adhesive portions 23a is relatively flexible and can meet the different connection needs between the bracket 2 and different windshields 10, thus having a wide range of applications.

[0090] Please see Figure 3In some embodiments, the bracket 2 may further include an adhesive layer 24. The adhesive layer 24 may be located between the first sealing ring 22 and the plate 211. The first sealing ring 22 can be fixedly connected to the first surface 2111 of the plate 211 through the adhesive layer 24. In this embodiment, the first sealing ring 22 is connected to the plate 211 by adhesive bonding, which simplifies the assembly process of the bracket body 21.

[0091] In other embodiments, the bracket body 21 and the first sealing ring 22 are integrally formed structural components. For example, the bracket body 21 and the first sealing ring 22 can be integrally formed by two-color injection molding, which simplifies the manufacturing process of the bracket 2 and makes it less likely for the first sealing ring 22 to detach from the bracket body 21.

[0092] In other embodiments, the plate 211 of the bracket body 21 may be provided with a first snap-fit ​​portion (not shown), and the first sealing ring 22 may be provided with a second snap-fit ​​portion (not shown), with the first snap-fit ​​portion and the second snap-fit ​​portion snapping together. For example, the plate 211 may be provided with a locking groove, and the first sealing ring 22 may be provided with a locking block, at least a portion of which may be located within the locking groove. It is understood that the positions of the locking groove and the locking block can be interchanged, that is, the locking block may be located on the plate 211, and the locking groove may be located on the first sealing ring 22. In this embodiment, the first sealing ring 22 can be connected to the bracket body 21 by setting a snap-fit, and setting a snap-fit ​​portion facilitates the positioning and assembly of the first sealing ring 22 and the bracket body 21.

[0093] In other embodiments, the first sealing ring 22 can be welded to the plate 211. For example, the first sealing ring 22 can be fixedly connected to the plate 211 by fusion welding, thereby improving the connection strength between the first sealing ring 22 and the plate 211.

[0094] In some embodiments, the material of the first sealing ring 22 may include at least one of polyurethane (PU), thermoplastic elastomer (TPE), and ethylene propylene diene monomer (EPDM). TPE is also known as synthetic rubber. Of course, the first sealing ring 22 may also be other soft materials capable of providing a sealing function.

[0095] In some embodiments, the material of the adhesive 23 may include at least one of adhesive, black glue, double-sided tape, and sealant. Of course, the adhesive 23 may also be other materials capable of performing an adhesive function.

[0096] Please see Figure 4 , Figure 4 yes Figure 2AThe diagram shows a partial structural representation of the sensing device 20 in some other embodiments. Exemplary, Figure 4 The main image shows the support 2 of the sensing device 20. Figure 4 The bracket 2 shown includes Figure 2B The following describes most of the technical features of the bracket 2 shown. The main difference between the two is described below, and the most common parts of the two will not be repeated.

[0097] In some embodiments, the adhesive 23 may surround the opening 214 of the receiving groove 213. It is understood that the adhesive 23 may surround the opening 214 of the receiving groove 213. For example, the adhesive 23 may be annular. This improves the connection strength between the bracket 2 and the windshield 10; it also allows the adhesive 23 to surround the first sealing ring 22, or the first sealing ring 22 to surround the adhesive 23. Therefore, when the bracket 2 is installed on the windshield 10 via the adhesive 23, the first sealing ring 22 can better seal the opening 214 of the receiving groove 213 under the action of the adhesive 23, thus improving the sealing effect of the first sealing ring 22.

[0098] Please refer to the following: Figure 2A , Figure 2B and Figure 5 , Figure 5 yes Figure 1B The diagram shows a partial structural view of the vehicle 100 cut along point BB in some embodiments. Figure 5 It can include Figure 2A The sensor device 20 shown.

[0099] In some embodiments, the groove 212 of the support body 21 may include a bottom wall 2121 and a side wall 2122. The side wall 2122 is fixedly connected to the plate 211, and the bottom wall 2121 is located on the side of the side wall 2122 away from the plate 211 and is fixedly connected to the side wall 2122. For example, Figure 5 The bottom wall 2121 and the side wall 2122 of the tank are schematically divided by dashed lines. The side wall 2122 may be provided with mounting holes 2123, which can connect to and accommodate the tank 213.

[0100] For example, the sidewall 2122 of the groove 212 may include a first side portion 2122a, a second side portion 2122b, and a third side portion 2122c. The first side portion 2122a is provided with the aforementioned mounting hole 2123. The second side portion 2122b and the third side portion 2122c are located on the same side of the first side portion 2122a and are connected to the first side portion 2122a. The second side portion 2122b and the third side portion 2122c are arranged at an angle. The angle between the second side portion 2122b and the third side portion 2122c can be in the range of 50° to 180°, such as 50°, 60°, 90°, 120°, 150°, 170°, etc.

[0101] In some embodiments, sensor 1 is mounted on bracket body 21 and is at least partially exposed relative to receiving groove 213 of bracket body 21. Exemplarily, sensor 1 may be mounted in mounting hole 2123, and at least a portion of sensor 1 may be exposed in mounting hole 2123.

[0102] In some embodiments, sensor 1 may include a camera 1a and a lidar 1b. The camera 1a can acquire image information in real time through a lens and an image sensor. The lidar 1b can obtain three-dimensional information about objects around the vehicle by emitting a laser beam and measuring the reflection time.

[0103] For example, mounting hole 2123 may include a first mounting hole 2123a and a second mounting hole 2123b. Camera 1a may be mounted in the first mounting hole 2123a. The lens of camera 1a may be exposed through the first mounting hole 2123a, so that light can enter the lens of camera 1a through the first mounting hole 2123a. LiDAR 1b may be mounted in the second mounting hole 2123b. The laser emitter and receiver of LiDAR 1b may be exposed through the second mounting hole 2123b, so that the laser emitted by the laser emitter can be emitted through the first mounting hole 2123a, and the target echo can be received from the second mounting hole 2123b. In some other embodiments, sensor 1 may not include camera 1a or LiDAR 1b.

[0104] In this embodiment, a field of view (FOV) exists between sensor 1 and windshield 10. The FOV of sensor 1 includes the FOV of camera 1a and the FOV of lidar 1b. Figure 2A The FOV areas of camera 1a and lidar 1b are illustrated by dashed lines. Since the FOV area of ​​sensor 1 can be located within the receiving slot 213, the risk of frost and fogging in the FOV area located within the receiving slot 213 can be reduced by reducing the risk of frost and fogging within the receiving slot 213.

[0105] In some embodiments, the bracket 2 may further include a second sealing ring 25. The second sealing ring 25 may be disposed in the mounting hole 2123 and seal the hole wall of the mounting hole 2123 and the sensor 1. The second sealing ring 25 can prevent external high-temperature and high-humidity gases from entering the receiving groove 213 through the mounting hole 2123, thereby reducing the risk of frost and fogging in the receiving groove 213, and further reducing the risk of frost and fogging in the FOV area of ​​the sensor 1.

[0106] In this embodiment, the material of the second sealing ring 25 may include at least one of PU, TPE, and EPDM. Of course, the second sealing ring 25 may also be other soft materials that can perform a sealing function. The second sealing ring 25 can be fixedly connected to the wall of the mounting hole 2123 by means of bonding, snap-fitting, or welding, or the second sealing ring 25 may be integrally formed on the wall of the mounting hole 2123.

[0107] For example, the second sealing ring 25 may include a first sub-sealing ring 25a and a second sub-sealing ring (not shown). The first sub-sealing ring 25a may be disposed in the first mounting hole 2123a and sealingly connect the hole wall of the first mounting hole 2123a to the camera 1a. The second sub-sealing ring may be disposed in the second mounting hole 2123b and sealingly connect the hole wall of the second mounting hole 2123b to the lidar 1b.

[0108] The above embodiments describe one possible structure of the first sealing ring 22 (e.g.) Figure 2A and Figure 2B As shown, the first sealing ring 22 can be annular. The first sealing ring 22 can also have other structures; another possible structure of the first sealing ring 22 will be described below with reference to the relevant accompanying drawings.

[0109] Please see Figure 6 , Figure 6 yes Figure 2A The schematic diagram of the sensing device 20 shown in some other embodiments. Figure 6 The sensor device 20 shown includes Figure 2A The following describes most of the technical features of the sensing device 20 shown. The main difference between the two is described below, and the most common parts of the two will not be repeated.

[0110] In some embodiments, the plate 211 may include a first portion 2113, a second portion 2114, a third portion 2115, and a fourth portion 2116. The first portion 2113, the second portion 2114, the third portion 2115, and the fourth portion 2116 may surround the receiving groove 213. For example, Figure 6The diagram uses dashed lines to schematically divide the space into four parts: a first part 2113, a second part 2114, a third part 2115, and a fourth part 2116. The first part 2113 and the fourth part 2116 can be located on opposite sides of the receiving groove 213, with the first part 2113 connected to the first side portion 2122a of the groove body 212, and the fourth part 2116 connected to the bottom wall 2121 of the groove body 212. Similarly, the second part 2114 and the third part 2115 can be located on opposite sides of the receiving groove 213, with the second part 2114 connected to the second side portion 2122b of the groove body 212, and the third part 2115 connected to the third side portion 2122c of the groove body 212.

[0111] In some embodiments, the first sealing ring 22 may be disposed at the notch 221. The notch 221 of the first sealing ring 22 may be located at the first portion 2113 of the plate 211. Exemplarily, at least a portion of the notch 221 of the first sealing ring 22 is opposite to the mounting hole 2123 along the axial direction of the mounting hole 2123. It is understood that in the embodiments of this application, the sensor 1 is mounted on the first side portion 2122a of the groove 212, and the notch 221 of the first sealing ring 22 may be close to the first side portion 2122a of the groove 212, that is, the first sealing ring 22 may be close to the sensor 1 for heat dissipation of the sensor 1. In this way, the risk of frost and fogging caused by the high temperature and high humidity gas generated by the heat of the sensor 1 coming into contact with the windshield 10 can be reduced.

[0112] For example, the notch 221 of the first sealing ring 22 can be a continuous opening 214, in which case the first sealing ring 22 can be open-ring shaped. In other examples, the notch 221 of the first sealing ring 22 can be a honeycomb structure, that is, the notch 221 includes multiple spaced through holes. It is understood that the notch 221 of the first sealing ring 22 can also be in other forms to achieve heat dissipation of the sensor 1, and this application does not strictly limit the shape or arrangement of the notch 221 of the first sealing ring 22.

[0113] Please refer to the following: Figure 7 and Figure 8 , Figure 7 yes Figure 2A The schematic diagram of the sensing device 20 shown in some embodiments is shown. Figure 8 yes Figure 7 The schematic diagram shown is a partial cross-sectional view of the sensing device 20 cut along CC in some embodiments. Figure 9 yes Figure 7 The diagram shows a partial cross-sectional view of the sensing device 20 cut along CC in some other embodiments.

[0114] In some embodiments, the groove 212 of the support body 21 may be provided with a vent 215, which can communicate with the receiving groove 213. For example, the vent 215 may be located on the bottom wall 2121 of the groove 212. In other examples, the vent 215 may also be located at other positions on the groove 212, such as on the side wall 2122 of the groove 212.

[0115] In some embodiments, the bracket 2 further includes a filter element 26. The filter element 26 can be fixedly connected to the groove 212 of the bracket body 21 and covers the vent 215. The filter element 26 is used for waterproofing and ventilation. In this embodiment, the filter element 26 can allow air to enter and exit the receiving groove 213 through the vent 215 to balance the air pressure in the receiving groove 213. At the same time, the filter element 26 can absorb the moisture generated in the receiving groove 213 and reduce the moisture of the air entering the receiving groove 213, thereby reducing the humidity of the air in the receiving groove 213 and reducing the risk of frost and fogging in the receiving groove 213.

[0116] It is understood that at least a portion of the filter element 26 may be located on the side of the tank 212 away from the receiving tank 213, or within the receiving tank 213, or within the vent 215. This application does not impose strict limitations on this.

[0117] like Figure 8 As shown, exemplarily, the filter element 26 can be a drying box, in which case the filter element 26 includes a desiccant 261. The desiccant 261 can be placed inside the housing 262 and fixedly connected to the tank 212 through the housing 262. The desiccant 261 can be magnesium chloride desiccant 261. In this embodiment, using desiccant 261 as the filter element 26 is beneficial for cost reduction. Exemplarily, the vent 215 can be a honeycomb pore. In some other examples, the vent 215 can also be a continuous through hole. This application does not strictly limit this.

[0118] like Figure 9 As shown, in some embodiments, the filter element 26 can be a waterproof and breathable membrane. A waterproof and breathable membrane can better prevent moisture from entering the receiving groove 213, providing better anti-fogging effects. Of course, the filter element 26 can also be other waterproof and breathable structural components. Exemplarily, the vent 215 can be a continuous through-hole. In some other examples, the vent 215 can also be a honeycomb structure. This application does not impose strict limitations on this.

[0119] Please refer to the following: Figure 10 and Figure 11 , Figure 10 yes Figure 2A The schematic diagram of the sensing device 20 shown in some embodiments is shown. Figure 11 yes Figure 10The diagram shows a partial cross-sectional view of the sensing device 20 along DD in some embodiments.

[0120] In some embodiments, the bracket 2 may further include a heating element 27, which may be fixedly connected to the bottom wall 2121 and / or the side wall 2122 of the tank 212. The heating element 27 is used to generate heat when energized, so as to raise the temperature inside the receiving tank 213, disrupt the thermal balance ecosystem inside the receiving tank 213, thereby achieving the effect of defogging and defrosting.

[0121] For example, the heating element 27 may include at least one of a metal wire, a metal sheet, a metal film, a printed line, a graphene heating element, and a graphene coating. The heating element 27 has a simple structure and can generate heat when energized, with a simple heating method. In this embodiment, the support 2 may also include a power supply for powering the heating element 27, or the heating element 27 may be electrically connected to an external power source via wires, electrical terminals, or other electrical connectors to energize the heating element 27. For example, the heating element 27 may include multiple spaced heating sections, or it may be a single integral structural component. This application does not impose strict limitations on this aspect.

[0122] In this embodiment, the heating element 27 can be used to heat the inner surface 101 of the windshield 10, thereby reducing fogging or accelerating fog removal. Furthermore, compared to a solution where the heating element is located on the windshield, this embodiment places the heating element 27 on the groove 212, for example, on the groove sidewall 2122 of the groove 212, thus avoiding the FOV area of ​​the sensor 1. Figure 10 The FOV areas of camera 1a and lidar 1b are illustrated by dashed lines, which avoids the influence of heating element 27 on the optical imaging effect of sensor 1 (including camera 1a and / or lidar 1b), such as edge diffraction and image shadow problems.

[0123] In some other embodiments, the windshield 10 may include a glass body (not shown) and a heating element (not shown) fixed to the glass body. The heating element of the windshield 10 may be a heating wire and / or silver paste wire. The heating element of the windshield 10 and the heating element 27 of the bracket 2 can heat up simultaneously to improve the efficiency of defrosting and defogging.

[0124] Please refer to the following: Figure 11 and Figure 12A , Figure 12A yes Figure 11 Enlarged view of a partial cross-sectional structure of the vehicle 100 shown at point M.

[0125] In some embodiments, the heating element 27 may cover the vent hole 215 of the tank 212 to increase the heating area. The heating element 27 is provided with a vent hole 271, which communicates with the vent hole 215 of the tank 212. For example, the vent hole 271 may be arranged opposite to the vent hole 215. The heating element 27 may allow air to enter and exit the receiving tank 213 through the vent hole 271 to balance the air pressure in the receiving tank 213.

[0126] In some embodiments, the outer surface of the heating element 27 may include an exposed area 272 protruding from the receiving groove 213, and the exposed area 272 may be provided with a matte structure. For example, a matte structure can be formed in the exposed area 272 of the heating element 27 by providing a matte texture, a serrated texture, or by spraying a matte paint, covering the surface with matte non-woven fabric, or other matte materials. In this embodiment, by providing a matte structure in the exposed area 272 of the heating element 27, reflections in the exposed area 272 of the heating element 27 under sunlight or artificial light can be avoided, thus preventing any impact on the optical imaging effect of the sensor 1.

[0127] In some embodiments, the orthographic projection of the heating element 27 onto the tank 212 at least partially covers the orthographic projection of the drying element 263 onto the tank 212. It is understood that the orthographic projection of the heating element 27 onto the tank 212 may completely cover the orthographic projection of the drying element 263 onto the tank 212, or it may partially cover the orthographic projection of the drying element 263 onto the tank 212. The temperature around the heating element 27 rises when it generates heat. In this embodiment, the drying element 263 is provided to absorb the water vapor generated around the heating element 27 due to the increased temperature.

[0128] It is understandable that when the heating element 27 and the drying element 263 are fixedly connected to the bottom wall 2121 of the tank body 212, the orthographic projection of the heating element 27 on the tank body 212 refers to the projection along the thickness direction of the bottom wall 2121; similarly, the orthographic projection of the drying element 263 on the tank body 212 refers to the projection along the thickness direction of the bottom wall 2121. When the heating element 27 and the drying element 263 are fixedly connected to the side wall 2122 of the tank body 212, the orthographic projection of the heating element 27 on the tank body 212 refers to the projection along the thickness direction of the side wall 2122; similarly, the orthographic projection of the drying element 263 on the tank body 212 refers to the projection along the thickness direction of the side wall 2122.

[0129] For example, the drying element 263 may be a drying box, which includes a desiccant 2631 and a housing 2632. The desiccant 2631 may be placed inside the housing 2632 and fixedly connected to the tank 212 via the housing 2632. The drying element 263 may be located on the side of the tank 212 away from the receiving groove 213 and cover the vent 215. The drying element 263 may also be located inside the receiving groove 213.

[0130] It is understood that when the filter element 26 in the above embodiment is a drying box, the filter element 26 can also be used as a drying element.

[0131] In other examples, the drying element 263 may also be a drying sheet or other components capable of absorbing moisture. This application does not impose strict limitations on the structure, material, or relative position of the drying element 263 to the receiving tank 213.

[0132] Please refer to the following: Figures 11 to 12B , Figure 12B yes Figure 11 Enlarged view of a partial structure at point M of some embodiments of the cross-sectional structure of the vehicle 100 shown.

[0133] In some embodiments, the support 2 may further include an insulation element 28. For example... Figure 12A As shown, in some examples, the insulation element 28 can be fixedly connected to the heating element 27 or the tank 212, and the insulation element 28 can be located on the side of the heating element 27 away from the receiving tank 213. Exemplarily, the material of the insulation element 28 can include at least one of sponge, foam, and aluminum foil. The insulation element 28 can be used to maintain the temperature of the heating element 27 after power is cut off, so that more heat can be transferred to the receiving tank 213, thereby ensuring defogging efficiency. Figure 12B As shown, in some other examples, the insulation element 28 may also be fixedly connected to the groove 212, and the insulation element 28 may be located on the side of the heating element 27 away from the receiving groove 213.

[0134] Understandable, Figure 12A The structure shown is Figure 12B The main difference in the structure shown lies in the relative position of the heating element 27 and the tank 212. In this embodiment, the heating element 27 can be located on the side of the tank 212 away from the receiving groove 213, or it can be located on the side of the tank 212 closer to the receiving groove 213 (i.e., the heating element 27 can be located inside the receiving groove 213). It is understood that the relative position of the heating element 27 and the tank 212 can be adjusted according to the heating power of the heating element 27, so that the heating power when the heating element 27 is located outside the receiving groove 213 can be greater than the heating power when the heating element 27 is located inside the receiving groove 213. Conversely, the heating power of the heating element 27 can also be adjusted according to the relative position of the heating element 27 and the tank 212.

[0135] Please refer to the following: Figure 13 and Figure 14 , Figure 13 yes Figure 2A The schematic diagram of the sensing device 20 shown in some embodiments is shown. Figure 14 yes Figure 13 The diagram shows a partial cross-sectional view of the sensing device 20 along EE in some embodiments.

[0136] In some embodiments, the bracket 2 may further include a matting element 29, which may be located within the receiving groove 213. Exemplarily, the matting element 29 may cover the bottom wall 2121 and the side wall 2122 of the groove 212.

[0137] For example, the matte element 29 may also cover the heating element 27. It is understood that by providing the matte element 29, which covers the exposed area 272 of the heating element 27, the exposed area 272 of the heating element 27 (see [link to documentation])... Figure 11 and Figure 12A It is not necessary to set an matting structure.

[0138] For example, the matting element 29 may cover the vent 215 of the groove 212. The matting element 29 may be provided with vents 291, which may be connected to the vent 215 of the groove 212.

[0139] In some other embodiments, the support 2 may not include the matting element 29, or the matting element 29 may not completely cover the bottom wall 2121 and side wall 2122 of the tank. In this case, the tank body 212 may include an exposed surface facing the receiving tank 213 and not covered by the matting element 29 and the heating element 27, and the exposed surface may be provided with a matting structure.

[0140] Please refer to the following: Figure 15 and Figure 16 , Figure 15 yes Figure 2A The schematic diagram of the sensing device 20 shown in some embodiments is shown. Figure 16 yes Figure 15 The diagram shows a partial cross-sectional view of the sensing device 20 along FF in some embodiments.

[0141] In some embodiments, the bracket 2 may further include a first temperature sensor 31, a second temperature sensor 32, and a humidity sensor 33. The first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33 may all be disposed in the receiving groove 213. Exemplarily, the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33 may all be fixedly connected to the side wall 2122 or the bottom wall 2121 of the groove body 212. For example, the side wall 2122 or the bottom wall 2121 of the groove body 212 may be provided with multiple positioning grooves (not shown) for mounting the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33. The first temperature sensor 31 is used to detect the temperature within the receiving groove 213, the second temperature sensor 32 is used to detect the temperature of the inner surface 101 of the windshield 10, and the humidity sensor 33 is used to detect the humidity within the receiving groove 213.

[0142] It is understood that the main purpose of this application embodiment is to avoid frost and fogging in the FOV area of ​​sensor 1, that is, to avoid frost and fogging in the receiving groove 213. Therefore, it is necessary to detect the temperature and humidity in the receiving groove 213, as well as the temperature of the inner surface of the windshield 10, to calculate the dew point (Td). In this embodiment, the dew point can be calculated by detecting the temperature and humidity in the receiving groove 213. Combined with the dew point, the allowable temperature (Ta) can be calculated, where the allowable temperature Ta = Td + Δ1 (Δ1 is a bias value and can be calibrated according to the actual situation). By comparing the temperature of the inner surface 101 of the windshield 10 with the allowable temperature (Ta), it is possible to control whether the heating element 27 needs to be energized to reduce fogging or defogging.

[0143] In some embodiments, the bracket 2 may further include a processor 34. The processor 34 may be fixedly connected to the bracket body 21, for example, the processor 34 may be fixedly connected to the plate 211 and located on the side of the plate 211 away from the first surface 2111, or the processor 34 may be fixedly connected to the groove 212 and located on the side of the groove 212 away from the receiving groove 213. The processor 34 is electrically connected to the heating element 27, the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33. The processor 34 is used to control whether the heating element 27 is energized based on the detection values ​​of the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33.

[0144] In this embodiment, the first temperature sensor 31 can detect the temperature inside the cavity and transmit the first temperature information to the processor 34. The humidity sensor 33 can detect the humidity inside the cavity and transmit the humidity information to the processor 34. The second temperature sensor 32 can detect the temperature inside the cavity and transmit the second temperature information to the processor 34. The processor 34 can calculate the dew point based on the first temperature information and the humidity information, and determine the allowable temperature (Ta) based on the dew point.

[0145] The processor 34 compares the temperature of the inner surface of the windshield 10 with the allowable temperature (Ta) based on the second temperature information. If the temperature of the inner surface of the windshield 10 is lower than the allowable temperature (Ta), the processor controls the heating element 27 to be energized to raise the temperature of the inner surface 101 of the windshield 10, thereby achieving the purpose of defogging. If the temperature of the inner surface of the windshield 10 rises to the safe temperature (Ts), where the safe temperature Ts = Ta + Δ2 (Δ2 is an offset value that can be calibrated according to actual conditions), the processor 34 can control the heating element 27 to stop being energized.

[0146] It is understood that in the above embodiments, the processor 34 is a component on the bracket 2, that is, the processor 34 is part of the bracket 2. In some other embodiments, the processor 34 may also be a component on the sensing device 20 or the vehicle 100. In this case, the heating element 27, the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33 on the bracket 2 can be electrically connected to the processor 34 on the sensing device 20 or the vehicle 100, and the processor 34 on the sensing device 20 or the vehicle 100 can control whether the heating element 27 is energized.

[0147] Please see Figure 17 , Figure 17 yes Figure 2A The schematic diagram of the sensing device 20 shown in some other embodiments. Figure 17 The sensor device 20 shown includes Figure 15 The following describes most of the technical features of the sensing device 20 shown. The main difference between the two is described below, and the most common parts of the two will not be repeated.

[0148] In some embodiments, the bracket 2 may include a temperature and humidity sensor 35. The temperature and humidity sensor 35 may be a conventional temperature and humidity sensor. The temperature and humidity sensor 35 can be used to detect the temperature inside the receiving groove 213, the temperature of the inner surface 101 of the windshield 10, and the humidity inside the receiving groove 213. The processor 34 can control whether the heating element 27 is energized based on the detection values ​​of the first temperature sensor 31, the second temperature sensor 32, and the humidity sensor 33. In this case, the bracket 2 may not include... Figure 15 The first temperature sensor 31, humidity sensor 33, and second temperature sensor 32 are shown in the figure.

[0149] It is understood that the sensing device 20 in this embodiment and Figure 15 The main difference of the sensing device 20 shown is that this embodiment uses a temperature and humidity sensor 35 instead of a temperature and humidity sensor. Figure 15 The first temperature sensor 31, humidity sensor 33, and second temperature sensor 32 shown are also... Figure 15 The first temperature sensor 31, humidity sensor 33, and second temperature sensor 32 shown are integrated. Of course, in some other embodiments, the bracket 2 may also use other detection components to replace the first temperature sensor 31, second temperature sensor 32, and third temperature sensor 1 for detecting the temperature inside the receiving groove 213, the temperature of the inner side 101 of the windshield 10, and the humidity inside the receiving groove 213.

[0150] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0151] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
