Technical Field

[0002] With the rapid development of electric and intelligent vehicles, more and more cameras are being installed on vehicles. Among these, cameras used outside the vehicle, such as side-view and rear-view cameras for driving, and surround-view cameras for low-speed parking, often experience internal fogging due to severe temperature fluctuations. Furthermore, in cold winter weather, the outer surface of these cameras' lenses often becomes coated with a thick layer of frost, which affects the camera's perception capabilities and can potentially lead to collisions, scratches, and other potential risks, threatening the lives of drivers and passengers in severe cases. Therefore, timely and proactive defogging and defrosting of these cameras' lenses is essential.
[0003] Related technologies primarily utilize heating modules placed within the front and rear housings of extravehicular cameras, close to the printed circuit board assembly (PCBA), to defog and defrost the lenses of these cameras. A PCBA is a fully functional electronic assembly that utilizes surface mount and plug-in technologies to mount and solder various electronic components, such as chips, resistors, capacitors, and inductors, onto a printed circuit board (PCB). These components play a key role in signal processing and function control within the extravehicular camera. However, this method suffers from low defog and defrost efficiency and compromises the heat dissipation and service life of the PCBA within the extravehicular camera. This, in turn, impacts the camera's heat dissipation efficiency and service life. Summary of the Invention

[0040] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION
[0041] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0042] Exterior cameras typically have multiple layers of lenses. The inner surface of the outermost lens can increase due to moisture inside the camera, or due to the large size of the camera housing, water vapor can enter during prolonged high-humidity environments. This can cause the camera to heat up when powered on, transferring heat from the camera cavity to the lens through the filter dispensing area. This transfer creates a temperature difference between the inside and outside of the cavity, causing the hot, moisture-laden air inside the lens to condense on the relatively cooler inner surface of the first lens. In winter, when ambient temperatures are low, saturated water vapor in the air can condense into frost on the cool outermost lens surface. This phenomenon is more likely to occur during periods of diurnal temperature swings, rain, snow, or cold weather, affecting the camera's perception capabilities and potentially leading to collisions, scrapes, and other potential risks. In severe cases, it can threaten the lives of drivers and passengers.
[0043] Figure 1 Schematic diagram of the structure of the extravehicular application camera in the related technology Figure 1 .like Figure 1 As shown, in the related art, a heating module is arranged inside the housing of an extravehicular camera near the PCBA. When the heating module generates heat to defog and defrost the outermost lens of the camera, the heat dissipation efficiency of the PCBA is reduced, thereby affecting the service life of the PCBA in the extravehicular camera. In addition, since there are multiple layers of lenses in the camera, the distance between the heating module and the outermost lens is relatively far, resulting in low efficiency in defogging and defrosting the outermost lens.
[0044] Figure 2 Schematic diagram of the structure of the extravehicular application camera in the related technology Figure 2 In addition to the above-mentioned related technologies, Figure 2As shown, in another related technology, the camera for extravehicular application has a high processing cost because the camera barrel needs to drill a deep small hole to pass the guide wire. In addition, the outer diameter of the outermost lens needs to be enlarged, which increases the cost of the outermost lens. The camera for extravehicular application is large in size, which is not conducive to arrangement and installation on the whole vehicle. Due to the increase in the size of the lens barrel, the camera for extravehicular application requires a large machine tool, and the processing accuracy will decrease, which in turn affects the optical performance of the camera for extravehicular application. In addition, this type of extravehicular application camera is difficult to assemble and has low reliability.
[0045] The extravehicular camera provided herein places a heating module outside the camera body, near the camera's outermost lens. This allows the heat generated by the heating module to be efficiently transferred to the outermost lens, improving defogger and defrost efficiency. Furthermore, the heating module can be positioned away from the PCBA, preventing heat generated by the heating module from affecting the heat dissipation and service life of the PCBA in the extravehicular camera, thereby increasing the camera's service life. Furthermore, since the heating module is located outside the camera body, there's no need to drill holes in the camera lens barrel or expand the outer diameter of the outermost lens. This reduces the processing cost and improves processing accuracy, easing assembly difficulty and enhancing reliability.
[0046] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0047] Figure 3 Schematic diagram of the structure of the extravehicular application camera provided in the embodiment of the present application Figure 1 .like Figure 3 As shown, the extravehicular application camera 10 includes: a camera body 11 and a heating module 12.
[0048] The heating module 12 is arranged outside the camera lens barrel 13 in the camera body 11 and adjacent to the outermost lens 14 . The heating module 12 defogs and defrosts the outermost lens 14 when powered on.
[0049] Specifically, the camera body 11 is a module with image acquisition function. The camera body 11 includes a camera barrel 13, a camera outer pressure ring 15, a camera spacer 16, a camera lens and a PCBA arranged inside the camera body. The camera lens is a multi-layer lens structure and is fixed in the camera barrel 13. The lens on the side closest to the external environment is the outermost lens 14. Fog or frost usually occurs on the inner surface or outer surface of the outermost lens 14.
[0050] When powered, heating module 12 converts electrical energy into heat. Located outside camera barrel 13 and adjacent to outermost lens 14, heating module 12 activates heating when fog or frost forms on outermost lens 14, warming and removing the fog or frost. Because heating module 12 is located outside the extravehicular camera, and further from the PCBA inside, it addresses the prior art issue of heating module 12 affecting the PCBA's heat dissipation efficiency and service life.
[0051] In some embodiments, the heating module 12 includes a heating coil that can convert electrical energy into thermal energy. For example, the heating coil can be an electromagnetic induction heating coil, a resistance wire heating coil, a ceramic heating coil, or a polyimide heating film coil, etc., which can convert electrical energy into thermal energy.
[0052] As a specific example, in the heating module 12, a polyimide heating diaphragm coil is used as a heating coil. The polyimide heating diaphragm coil is attached to the camera barrel 13 near the outermost lens 14. The heating module 12 obtains electricity through the vehicle power supply, so that the polyimide heating diaphragm coil generates heat to heat the camera barrel 13. The camera barrel 13 transfers the heat to the outermost lens 14. After the outermost lens 14 is heated, the frost on the outer surface can be removed, and the water mist on the inner surface can also be removed.
[0053] Optionally, the heating module 12 is controlled by a heating module controller. When the heating module controller detects that there is fog or frost on the outermost lens, it controls to start the heating module 12 to defog and defrost the outermost lens.
[0054] Optionally, a temperature sensor can be integrated into the camera body 11 to collect the real-time temperature of the outermost lens 14. The heating module controller obtains the temperature of the outermost lens 14 via the temperature sensor and controls the operation of the heating module 12 based on the relationship between the real-time temperature of the outermost lens 14 and a preset temperature threshold. For example, when the temperature of the outermost lens 14 falls below the preset temperature threshold, indicating that the outermost lens 14 is prone to fogging and frosting, the heating module 12 is activated to promptly heat the outermost lens 14 to the preset temperature threshold to prevent fogging and frosting.
[0055] The extravehicular application camera provided in the embodiment of the present application sets the heating module on the outside of the camera lens barrel and near the outermost lens position of the camera lens barrel, which reduces the processing difficulty of the extravehicular application camera, effectively achieves the effect of defogging and defrosting the outermost lens, and improves the heat dissipation efficiency and service life of the PCBA inside the extravehicular application camera.
[0056] In one possible implementation, the heating module is disposed on the outer circumference of the camera lens barrel;
[0057] And / or, the heating module is arranged on the camera outer pressure ring of the camera body.
[0058] For example, Figure 3 As shown, the heating module 12 is arranged on the outer circumference of the camera lens barrel 13. In order to facilitate installation, the heating coil in the heating module is made of flexible material, which can be attached and surrounded on the outer circumference of the camera lens barrel 13 and can well adapt to various lens barrel sizes and shapes.
[0059] Figure 4 Schematic diagram of the extravehicular camera structure provided in the embodiment of this application Figure 2 Another example is Figure 4 As shown, the heating module 12 is arranged on the outer pressure ring 15 of the camera.
[0060] In the camera used outside the cabin, the camera outer pressure ring 15 plays the role of pressing, protecting and fixing the internal lens of the lens. The internal lens of the lens includes the outer lens 14. Installing the heating module 12 on the camera outer pressure ring 15 can efficiently heat the outermost lens 14, thereby achieving the effect of defogger and defrost.
[0061] As another example, a heating module 12 may be provided on both the outer circumference of the camera barrel 13 and the camera outer pressure ring 15 to achieve an effect of efficiently heating the outermost lens 14 .
[0062] The extravehicular application camera provided in the embodiment of the present application sets the heating module on the outer circumference of the camera barrel and / or the outer pressure ring of the camera, shortening the distance between the heating module and the outermost lens, improving the heat transfer efficiency, and efficiently defogging and defrosting the outermost lens.
[0063] In one possible embodiment, when the heating module is arranged on the outer pressure ring of the camera, the heating module is arranged on the outer circumference of the side of the outer pressure ring of the camera away from the outermost lens, and / or the heating module is arranged on the end face of the end of the outer pressure ring of the camera away from the outermost lens.
[0064] Figure 5 Schematic diagram of the extravehicular camera structure provided in the embodiment of this application Figure 3 . Reference Figure 5 The heating module 12 is arranged on the rear circumference of the camera outer pressure ring 15, wherein the rear side of the camera outer pressure ring 15 refers to the side of the camera outer pressure ring 15 away from the outermost lens 14. This arrangement can ensure the defogger and defrost efficiency of the heating module 12 without affecting the overall appearance of the camera for extravehicular applications.
[0065] Reference Figure 4 In another example, the heating module 12 is arranged on the rear end face of the camera outer pressure ring 15, wherein the rear side of the camera outer pressure ring 15 refers to the side of the camera outer pressure ring 15 away from the outermost lens 14. Similar to the arrangement on the rear circumference, this arrangement can ensure the defogger and defrost efficiency of the heating module 12 without affecting the overall appearance of the camera for extravehicular application.
[0066] The heat generated by the heating module 12 is transferred to the camera outer pressure ring 15, the camera outer pressure ring 15 is transferred to the camera barrel 13, and the camera barrel 13 is transferred to the outermost lens 14. After the outermost lens 14 is heated, the frost on the outer surface can be removed, and the water mist on the inner surface can also be removed.
[0067] The extravehicular application camera provided in the embodiment of the present application sets the heating module on the rear outer circumference and / or rear end face of the camera outer pressure ring, while ensuring the defogger and defrost efficiency without affecting the appearance of the extravehicular application camera.
[0068] In a possible implementation, the camera lens barrel and the camera outer pressure ring are both made of aluminum alloy or copper alloy.
[0069] As described in the above embodiments, the heating module is arranged on the camera barrel and / or the camera outer pressure ring. In order to efficiently transfer heat to the outermost lens, the camera barrel and the camera outer pressure ring should both be made of materials with good thermal conductivity, such as aluminum alloy or copper alloy.
[0070] Aluminum alloy is light, low-cost and corrosion-resistant. Using aluminum alloy to make camera lens barrels or camera outer pressure rings can make extravehicular cameras lightweight and low-cost.
[0071] The core advantage of copper alloy as a thermal conductive material lies in its excellent thermal conductivity, outstanding electrical conductivity, strong corrosion resistance, and outstanding processing ductility. It can still maintain stable thermal conductivity under various harsh conditions. Therefore, using copper alloy to make the camera lens barrel or the camera outer pressure ring can make the camera lens barrel or the camera outer pressure ring have the effect of efficiently transferring heat energy, which can improve the efficiency of the heating module in defogging and defrosting the outermost lens.
[0072] The extravehicular application camera provided in the embodiment of the present application has a camera barrel and a camera outer pressure ring made of aluminum alloy or copper alloy, which can efficiently transfer the heat generated by the heating module to the outermost lens, thereby improving the defogger and defrost efficiency.
[0073] In a possible implementation, the heating module is powered by a vehicle power supply.
[0074] When the heating module is installed inside the extravehicular camera, it must be powered by the camera's internal power supply and wiring harness. This increases the camera's structural complexity, and the amount of power required to generate heat significantly increases the camera's energy consumption. Furthermore, repairing or replacing the heating module requires disassembling the entire camera, a complex process.
[0075] To reduce the complexity and power consumption of the extravehicular camera, and to improve its reliability and lifespan, the heating module draws power from the vehicle's wiring harness rather than from the camera itself. Specifically, power is transmitted from the vehicle's power supply to the heating module via a power harness. One end of the harness is connected to the vehicle's power supply, while the other end is connected to the heating module. When the power module is activated, it draws power directly from the vehicle's power supply, converting it into heat to defog and defrost the outermost lens of the extravehicular camera.
[0076] Optionally, a separate battery pack can be set up to power the heating module, so that the installation position of the heating module is no longer limited by the power supply of the entire vehicle and the position of the power supply wiring harness. Users can adjust the setting position of the heating module according to their actual usage experience, thereby improving the flexibility of use of the heating module.
[0077] The extravehicular application camera provided in the embodiment of the present application has a heating module that is powered by the vehicle's power supply, which can reduce the complexity and power consumption of the extravehicular application camera. Moreover, since the power supply harness is outside the extravehicular application camera, when the heating module needs to be disassembled and replaced, the extravehicular application camera does not need to be disassembled, thereby improving the convenience of inspection and replacement.
[0078] Figure 6 This is a front view of the heating module structure provided in the embodiment of the present application. Figure 7 A side view of the heating module structure provided in the embodiment of the present application. In one possible embodiment, Figure 6 and Figure 7 As shown, the heating module includes a heating coil 121, a wire 122 and a connector 123;
[0079] The heating coil 121 is connected to the connector 123 via a wire 122 , and the connector 123 is connected to the vehicle power supply via a power supply harness.
[0080] Among them, the heating coil 121 is made of a material that can generate heat when powered on, and obtains electrical energy through a wire 122 and a connector 123. The heating coil 121 can achieve precise temperature control and local heating. By attaching the heating coil to the camera barrel or the outer pressure ring of the camera, efficient and directional heat transfer can be achieved, avoiding energy waste caused by overall heating. The heating coil 121 has a high electrothermal conversion efficiency and low energy loss. It heats up almost instantly after being powered on, without waiting for preheating, and can meet the demand for rapid heating. In addition, the heating coil 121 has a relatively simple structure, no complex moving parts, low maintenance requirements, long life, and high reliability.
[0081] Connector 123 can control the on and off of the power supply of the heating module. When the heating module needs to be disassembled and replaced, the heating module can be disconnected from the power supply of the entire vehicle through connector 123, thereby realizing easy disassembly of the heating module.
[0082] The extravehicular application camera provided in the embodiment of the present application has a heating coil provided in the heating module, which has high heating efficiency and high reliability. It is connected to the power supply of the entire vehicle through wires and connectors, thereby reducing the power consumption of the extravehicular application camera. The heating module can also be disconnected from the power supply of the entire vehicle, making the heating module easy to disassemble and assemble.
[0083] In a possible implementation, the heating coil is a polyimide heating diaphragm coil.
[0084] Specifically, polyimide is used to create a polyimide heating film coil. This high-tech functional material combines the remarkable physical and chemical properties of polyimide with electrothermal conversion technology. It is achieved by precisely printing or etching a resistive circuit layer, such as constantan, nickel-chromium alloy, or carbon paste, onto a polyimide film substrate, then covering it with a protective polyimide layer to create a "sandwich" structure. This achieves efficient, stable, and ultra-thin electrothermal conversion.
[0085] Polyimide heating diaphragm coils are extremely thin, lightweight, and flexible, conforming to various curved surfaces and adapting well to the sizes and shapes of various camera lens barrels or camera retaining rings. Furthermore, polyimide heating diaphragm coils offer rapid heating response and a uniform surface temperature, enhancing the defogging and defrosting efficiency of the outermost lens.
[0086] Optionally, the heating coil can also be made of other materials with heat-generating functions, such as a graphene heating film coil. The graphene heating film coil has similar properties to the polyimide heating film coil and can be made very thin, hardly increasing the volume of the extravehicular camera or affecting its appearance design. In addition, the graphene heating film coil has good flexibility and can easily fit various curved surfaces, such as special-shaped camera barrels or camera outer pressure rings. In addition, the graphene heating film coil has the characteristics of efficient and rapid heating, uniform heat generation, low power consumption, and good temperature controllability. It can effectively heat the outermost lens of the extravehicular camera, effectively ensuring a clear field of view for the extravehicular camera in various harsh environments, and improving the reliability and safety of the equipment.
[0087] The extravehicular application camera provided in the embodiment of the present application uses a polyimide heating diaphragm coil as a heating coil, fully utilizing the physical and chemical properties of the polyimide heating diaphragm coil, and can achieve the effect of efficiently defogging and defrosting the extravehicular application camera and flexibly adapting to the sizes and shapes of various camera lens barrels or camera pressure rings.
[0088] In a possible implementation, the heating coil is fixed to the camera lens barrel or the camera outer pressure ring by adhesive.
[0089] The heating coil is made of a polyimide film or other flexible heating material, allowing it to flexibly fit various sizes and shapes of camera lens barrels or camera outer rings. To ensure flexible placement of the heating coil on the camera lens barrel or camera outer ring, the heating coil is secured with adhesive. This method not only makes installation easier, but also allows for simple removal of the heating coil, making it convenient for maintenance and replacement.
[0090] Optionally, in order to improve the firmness and reliability of the installation of the heating coil, the heating coil can be fixed to the camera barrel or the camera outer pressure ring by laser welding, plasma activated bonding, microneedle array mechanical locking or metallized through-hole riveting.
[0091] In the extravehicular application camera provided in the embodiment of the present application, the heating coil is fixed to the camera lens barrel or the camera outer pressure ring by adhesive, which makes the heating coil easy to assemble and disassemble, and can give full play to the advantages of the flexible material of the heating coil, so that the heating coil can fit well with camera lens barrels or camera outer pressure rings of various sizes and shapes.
[0092] In one possible implementation, refer to Figure 3 、 Figure 4 as well as Figure 5 The extravehicular camera further includes a plastic decorative cover 17 disposed on the camera body 11 for shielding the heating module 12 .
[0093] It is understandable that if Figure 3 、 Figure 4 as well as Figure 5 The middle plastic decorative cover 17 can fully shield the heating module 12 so that the heating module 12 does not affect the appearance of the camera used outside the cabin.
[0094] The extravehicular application camera provided in the embodiment of the present application is provided with a plastic decorative cover to shield the heating module, thereby ensuring the aesthetics of the extravehicular application camera.
