Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a window assembly and a vehicle. Background Technology

[0002] When there is a large temperature difference between the inside and outside of the vehicle during use, water droplets can easily condense and form fog on the surface of the car window glass.

[0003] Taking the rear window of a vehicle as an example, if fog appears in the rear window, it will blur the driver's vision when observing the rear, thus increasing the driving risk. Currently, to remove fog from the rear window, a resistance wire is often embedded in the rear window glass, using the heat of the resistance wire to defog.

[0004] However, since only thin resistance wires can be installed inside the rear windshield, and not only is the heating area of ​​the resistance wires limited, but the heat transfer in the rear windshield is also slow. As a result, the defogging speed of the rear windshield is slow, making it difficult to defog in a timely manner, which is not conducive to improving the overall quality of the vehicle. Utility Model Content

[0005] In view of this, this application aims to propose a window assembly to improve the overall quality of vehicle use.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows: A vehicle window assembly includes a window frame on which a window glass is disposed, and a defogging structure disposed on the window frame; The defogging structure includes a rotating cylinder mounted on the window frame, a drive assembly connected to the rotating cylinder, an inner air guide hood and an outer air guide hood respectively mounted on two opposite sides of the window frame, and a heating assembly is provided inside the rotating cylinder. The heating component is adapted to heat the demisting airflow entering the rotating drum, and under the drive of the driving component, the rotating drum can be in a first position communicating with the inner air guide shroud or a second position communicating with the outer air guide shroud. When the rotating drum is in the first position, the defogging airflow inside the rotating drum can be blown towards the inside of the vehicle window glass through the inner air guide shroud. When the rotating drum is in the second position, the defogging airflow inside the rotating drum can be blown towards the outside of the vehicle window glass through the outer air guide shroud.

[0007] Furthermore, the defogging structure includes a fan assembly disposed on the window frame; The air outlet of the fan assembly is connected to the inside of the rotating drum, and the fan assembly is adapted to deliver the demisting airflow into the rotating drum.

[0008] Furthermore, the rotating cylinder, the inner air guide hood, and the outer air guide hood are located at the top of the window frame, and the fan assembly is located at the bottom of the window frame.

[0009] Furthermore, the rotating cylinder is located inside the window frame, and the air outlet of the fan assembly communicates with the interior of the rotating cylinder through the inner cavity of the window frame; and / or, The air inlet of the fan assembly is located inside the window frame.

[0010] Furthermore, the air outlet of the outer air guide is located at the bottom of the outer air guide, and the air outlet direction of the outer air guide is downward and points towards the vehicle window glass; When the rotating drum is in the second position, the outer wall of the rotating drum can seal the communication position between the outer air guide shroud and the rotating drum.

[0011] Furthermore, the heating assembly includes an electric heater disposed inside the rotating drum, and one end of the rotating drum is provided with an electrical connector connected to the electric heater, the electrical connector being adapted to connect to an external power supply device.

[0012] Furthermore, the drive assembly includes a motor mounted on the window frame and a transmission unit located between the motor and the rotating drum, wherein the motor drives the rotating drum to rotate via the transmission unit.

[0013] Furthermore, the transmission unit includes a first transmission gear disposed on the power output end of the motor and a second transmission gear disposed on one end of the rotating drum, wherein the first transmission gear and the second transmission gear are meshed and connected.

[0014] Compared with related technologies, this application has the following advantages: (1) The window assembly described in this application provides air guides on the inner and outer sides of the window frame and a rotating cylinder with a heating component. The rotating cylinder can be driven to rotate so that it can selectively communicate with the inner air guide or the outer air guide. This not only allows the heating component to heat the defogging airflow entering the rotating cylinder to achieve hot air defogging of the window glass, but also allows for selective defogging of the inner or outer side of the window glass as needed. This increases the defogging speed of the window glass and improves the defogging efficiency of the window, thereby helping to improve the overall quality of the vehicle.

[0015] (2) The defogging structure further includes a fan assembly that delivers defogging airflow into the rotating drum, which avoids the troubles in vehicle design and assembly caused by using other airflow sources, helps to avoid a significant increase in vehicle design and manufacturing costs. At the same time, the use of specially designed fan assembly can also ensure the stability of the defogging airflow supply, which is conducive to ensuring the defogging effect of the vehicle window glass.

[0016] (3) The rotating cylinder and the air guides on both sides are located at the top of the window frame, and the fan assembly is located at the bottom of the window frame. This is advantageous because the window frame above and below the car window glass generally has ample space, which facilitates the installation of the rotating cylinder, air guides and fan assembly, and helps to reduce the overall design, development and manufacturing costs of the car window assembly.

[0017] (4) The rotating cylinder is located inside the window frame, and the air outlet of the fan assembly is connected to the rotating cylinder through the inner cavity of the window frame. By integrating the rotating cylinder into the window frame and using the window frame itself to form an air supply duct between the fan assembly and the rotating cylinder, the compact design of the window assembly can be achieved. This can reduce the number of parts of the defrosting structure, reduce the structural size of the window assembly, reduce the overall space occupied by the window, and facilitate the arrangement of the window assembly in the vehicle body.

[0018] The air inlet of the fan assembly is located inside the window frame, allowing the air inside the vehicle to serve as the air source for the defogging airflow. This not only takes advantage of the generally clean air inside the vehicle to ensure the cleanliness of the defogging airflow, but also utilizes the generally higher temperature of the air inside the vehicle to ensure a higher initial temperature for the defogging airflow in cold environments. This helps reduce the energy consumption of the heating components and also helps to ensure the temperature of the airflow blown onto the window glass, thus ensuring the defogging effect.

[0019] (5) The air outlet of the outer air guide is set at its bottom so that the air outlet of the outer air guide is downward. When the rotating cylinder is in the second position, the outer wall of the rotating cylinder can also seal the connection between the outer air guide and the rotating cylinder. When the rotating cylinder is connected to the inner air guide, it can prevent rainwater or car wash water from entering the window assembly, thus ensuring the waterproof performance of the window assembly and ensuring the quality of use when the window assembly is equipped with a defogging structure.

[0020] (6) The heating component adopts an electric heater installed inside the rotating drum, and the electric heater is connected to an external power supply device through an electrical connector located at one end of the rotating drum. The structure is simple and the technology is mature, which facilitates the installation and arrangement inside the rotating drum. At the same time, it also helps to ensure the heating effect of the demisting airflow entering the rotating drum.

[0021] (7) The drive component uses a motor and a transmission part that connects the motor and the rotating drum. The structure is simple, easy to design and implement, and helps to reduce the development and manufacturing costs of the drive component.

[0022] (8) The transmission part adopts a first transmission gear and a second transmission gear that are meshed together. The structure is simple, which is conducive to the design and assembly of the transmission part. It also helps to control the transmission ratio of the transmission part, which is conducive to ensuring the stability of the motor driving the lower drum to rotate.

[0023] Another object of this application is to provide a vehicle having a window assembly as described above.

[0024] Furthermore, the window always serves as the rear windshield of the vehicle; and / or, The window assembly is detachably mounted in the body of the vehicle.

[0025] By adopting the aforementioned window assembly, the vehicle described in this application can increase the defogging speed of the window glass, improve the defogging efficiency of the window, and contribute to the improvement of the overall vehicle quality.

[0026] Furthermore, by using the aforementioned window assembly for the rear window in the vehicle, efficient defogging of the window glass that constitutes the rear window can be achieved, ensuring that the driver has a clear rear view, reducing driving safety hazards caused by blurred vision, and thus improving the safety quality of the vehicle.

[0027] Secondly, it allows the window assembly to be detachably installed in the vehicle body, enabling a modular design of the window assembly. This modular design facilitates the design and manufacture of the window assembly, as well as its assembly in the vehicle body, and also makes it easier to maintain and repair the window assembly later.

Detailed Implementation

[0029] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0033] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0035] The first aspect of this application provides a window assembly, specifically a vehicle window equipped with a defogging structure. The window assembly of this embodiment, through its innovative structural design, can improve the defogging efficiency of the window and contribute to the improvement of the overall vehicle quality.

[0036] In related technologies, taking the rear window of a vehicle as an example, when there is a large temperature difference between the inside and outside of the vehicle, water droplets are easily condensed on the surface of the rear window glass, forming fog. When fog appears on the rear window, it will blur the driver's vision when observing the situation behind, which can easily lead to misjudgment and increase driving risks.

[0037] Currently, to remove fog from the rear windshield of a vehicle, existing designs typically embed resistance wires within the rear windshield glass, using the heat generated by the wires to conduct heat to the glass surface for defogging. However, due to the thickness of the rear windshield glass, only relatively thin resistance wires can generally be installed. This results in a limited heating area for the wires and slow heat transfer within the rear windshield. Consequently, the defogging speed at the rear windshield is slow, making it difficult to defog promptly and thus negatively impacting the overall vehicle performance.

[0038] In view of this, in order to overcome the shortcomings of the related technology, the window assembly of this embodiment combines... Figures 1 to 8 As shown, the overall design includes a window frame 1 with a window glass 2 and a defogging structure 3 installed on the window frame 1.

[0039] The aforementioned defogging structure 3 includes a rotating cylinder 301 mounted on the window frame 1, and a drive assembly 305 connected to the rotating cylinder 301. It also includes an inner air guide hood 302 and an outer air guide hood 303 mounted on opposite sides of the window frame 1, and a heating assembly 304 is provided inside the rotating cylinder 301.

[0040] The heating component 304 is adapted to heat the demisting airflow entering the rotating drum 301, and under the drive of the driving component 305, the rotating drum 301 can also be in a first position communicating with the inner air guide 302 or a second position communicating with the outer air guide 303.

[0041] When the rotating cylinder 301 is in the first position, the defogging airflow inside the rotating cylinder 301 can be blown towards the inside of the window glass 2 through the inner air guide 302. When the rotating cylinder 301 is in the second position, the defogging airflow inside the rotating cylinder 301 can be blown towards the outside of the window glass 2 through the outer air guide 303.

[0042] Therefore, by setting air guide hoods on the inner and outer sides of the window frame 1 respectively, and setting a rotating cylinder 301 with a heating component 304, and driving the rotating cylinder 301 to rotate, the rotating cylinder 301 can selectively communicate with the inner air guide hood 302 or the outer air guide hood 303. In this embodiment, the heating component 304 can be used to heat the defogging airflow entering the rotating cylinder 301 to achieve hot air defogging of the vehicle window glass 2. At the same time, it can also selectively and directly defog the inner or outer side of the vehicle window glass 2 as needed, which can increase the defogging speed of the vehicle window glass 2, improve the defogging efficiency of the vehicle window, and thus improve the overall vehicle quality.

[0043] Based on the above overview, it is worth noting that the window frame 1, as the main structure of the entire window assembly, can generally be designed according to the way the window assembly is installed in the vehicle body. For example, when the window assembly is integrated into the body, the window frame 1 can be made of the same material as the surrounding body structure and is usually made of sheet metal. However, when the window assembly is installed in the body as an independent structure, the window frame 1 can be made of sheet metal, or, provided that structural strength and other requirements are met, it is also possible to make the window frame 1 as an injection-molded plastic part.

[0044] In addition, it should be pointed out that, in Figures 1 to 4 The text only provides one feasible structural form for window frame 1. In actual implementation, besides... Figures 1 to 4 As shown, the window frame 1 has a regular rectangular structure. Of course, depending on the specific requirements of the vehicle model in which the window assembly of this embodiment is installed, the window frame 1 can also be designed into other shapes. When the window frame 1 is designed into other shapes, the shape of the window glass 2 can be adapted and installed on the window frame 1.

[0045] At this point, the window glass 2 can be selected based on the position of the window assembly in the vehicle according to this embodiment and the design requirements of the specific vehicle model. In practice, the window glass 2 can also be fixed to the window frame 1 using conventional glass installation methods, which will not be elaborated further.

[0046] In this embodiment, in some exemplary implementations, it is still based on Figures 1 to 5 Taking the window frame 1 shown as an example, structurally, the window frame 1 includes a frame 101 and a cover plate 102 connected to one side of the frame 101.

[0047] Both the frame 101 and the cover plate 102 are annular structures to form a window for housing the vehicle window glass 2. Furthermore, the frame 101 is hollow inside, and after the cover plate 102 is connected to the frame 101, a closed inner cavity 1a can be formed within the window frame 1.

[0048] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, the defogging structure 3 of this embodiment further includes a fan assembly 306 disposed on the window frame 1, the air outlet of the fan assembly 306 communicating with the inside of the rotating cylinder 301, and the fan assembly 306 being adapted to deliver defogging airflow into the rotating cylinder 301.

[0049] Thus, by further including a fan assembly 306 that supplies defogging airflow into the rotating cylinder 301 in the defogging structure 3, it is understandable that compared to using other airflow sources (such as vehicle air conditioning) to supply air into the rotating cylinder 301, this obviously avoids the troubles in vehicle design and assembly caused by using other airflow sources, and helps to avoid a significant increase in vehicle design and manufacturing costs. At the same time, using a specially designed fan assembly 306, compared to connecting to other airflow sources such as vehicle air conditioning through longer pipes, can also ensure the stability of the defogging airflow supply, thereby also helping to ensure the defogging effect of the window glass 2.

[0050] It should be noted that although using other airflow sources, such as vehicle air conditioning, may cause design and assembly difficulties compared to setting the aforementioned fan assembly 306, in specific implementation, in addition to setting a dedicated fan assembly 306, it is also possible to use airflow sources such as vehicle air conditioning to supply air to the defogging structure 3 of this embodiment. There is no restriction on this, as long as it can meet the usage requirements of the defogging structure and the vehicle's usage requirements.

[0051] In this embodiment, based on the above-mentioned fan assembly 306, in specific implementation, the fan assembly 306 can be a blower product with suitable size and air volume specifications.

[0052] In addition, see also Figures 1 to 4 As shown, taking the simultaneous installation of fan assembly 306 as an example, in some exemplary embodiments, this embodiment may, for example, place the rotating cylinder 301, the inner air guide shroud 302, and the outer air guide shroud 303 at the top of the window frame 1, and place the fan assembly 306 at the bottom of the window frame 1.

[0053] This arrangement places the rotating cylinder 301 and the air guide covers on both sides at the top of the window frame 1, and the fan assembly 306 at the bottom of the window frame 1. This takes advantage of the generally ample space in the window frame 1 above and below the window glass 2, which facilitates the placement of the rotating cylinder 301, the air guide covers, and the fan assembly 306, and helps to reduce the overall design, development, and manufacturing costs of the window assembly.

[0054] With the rotating cylinder 30 located at the top of the window frame 1 and the fan assembly 306 located at the bottom of the window frame 1, in some exemplary embodiments, this embodiment may, for example, have the rotating cylinder 301 located inside the window frame 1, and the air outlet of the fan assembly 306 communicate with the inside of the rotating cylinder 301 through the inner cavity 1a of the window frame 1.

[0055] Therefore, by placing the rotating cylinder 301 inside the window frame 1 and making the air outlet of the fan assembly 306 communicate with the rotating cylinder 301 through the inner cavity 1a of the window frame 1, this embodiment can obviously achieve a compact design of the window assembly by integrating the rotating cylinder 301 inside the window frame 1 and using the structure of the window frame 1 itself (i.e., the inner cavity 1a) to form an air supply duct between the fan assembly 306 and the rotating cylinder 301. This can reduce the number of parts in the defrosting structure, reduce the structural size of the window assembly, reduce the overall space occupied by the window, and facilitate the arrangement of the window assembly in the vehicle body.

[0056] Of course, it is also understandable that while the rotating cylinder 301 is set inside the window frame 1, the air outlet of the fan assembly 306 is connected to the inside of the rotating cylinder 301 through the inner cavity 1a of the window frame 1. Compared with the method of connecting the fan assembly 306 and the rotating cylinder 301 through the air supply duct, it is also convenient to realize the connection between the fan assembly 306 and the rotating cylinder 301 while the rotating cylinder 301 can rotate, which can also greatly reduce the design, development and manufacturing costs of the window assembly.

[0057] It is worth noting that, in specific implementation, the fan assembly 306 can be fixed to the bottom of the frame 101 using conventional connection methods such as snap-fit ​​or screw-fit, and a fan connection port 1b is provided at the bottom of the frame 101. This fan connection port 1b connects the air outlet of the fan assembly 306 to the inner cavity 1a of the window frame 1, allowing the airflow driven by the fan assembly 306 to enter the interior of the window frame 1, and then enter the rotating cylinder 301 through the inner cavity 1a of the window frame 1.

[0058] In addition, in specific implementation, since the airflow output by the fan assembly 306 enters the rotating cylinder 301 through the inner cavity 1a of the window frame 1, the inner cavity 1a of the window frame, the connection position between the fan assembly 306 and the window frame 1, and the connection position between the window frame 1 and the inner and outer air guide covers should all have good sealing performance to avoid air leakage and noise generation.

[0059] In this embodiment, combined with Figure 1 As shown, in some exemplary embodiments, the air inlet of the fan assembly 306 may be located, for example, inside the window frame 1.

[0060] At this time, since the inner side of the window frame 1 faces the passenger compartment of the vehicle, by setting the air inlet of the fan assembly 306 on the inner side of the window frame 1, it can be understood that this embodiment can make the air inside the vehicle the source of the defogging airflow. This not only takes advantage of the generally clean nature of the air inside the vehicle to ensure the cleanliness of the defogging airflow, but also takes advantage of the generally high temperature of the air inside the vehicle to make the defogging airflow have a higher initial temperature in cold environments. This is beneficial to reducing the energy consumption of the heating assembly 304 and also helps to ensure the temperature of the airflow blown toward the window glass 2, thus ensuring the defogging effect.

[0061] Continue as Figure 4 and Figure 5 As shown, in some exemplary embodiments of this embodiment, the air outlet of the outer air guide shroud 303, that is... Figure 5 The air outlet 3031 of the outer air hood is generally located at the bottom of the outer air guide hood 303, and specifically, the air outlet direction of the outer air guide hood 303 is downward and points towards the window glass 2. At the same time, when the rotating cylinder 301 is in the second position, the outer wall of the rotating cylinder 301 can also seal the connection between the outer air guide hood 303 and the rotating cylinder 301.

[0062] It is understandable that by setting the air outlet of the outer air guide 303 at its bottom, the air outlet direction of the outer air guide 303 is downward, and when the rotating cylinder 301 is in the second position, the outer wall of the rotating cylinder 301 can seal the connection between the outer air guide 303 and the rotating cylinder 301. In this embodiment, when the rotating cylinder 301 is connected to the inner air guide 302, rainwater or car wash water from the outside can be prevented from entering the window assembly through the outer air guide 303, thereby ensuring the waterproof performance of the window assembly and ensuring the quality of use when the window assembly is equipped with a defrosting structure.

[0063] In one exemplary embodiment, to achieve communication between the window frame 1 and the inner air guide hood 302 and the outer air guide hood 303, for example, an outer air guide hood communication port 101a can be provided on the frame 101 in the window frame 1, and an inner air guide hood communication port 102a can also be provided on the cover plate 102.

[0064] Meanwhile, both the inner air guide hood 302 and the outer air guide hood 303 are open on one side. When the inner and outer air guide hoods are connected to the window frame 1, the open part on the side of the inner air guide hood 302 is connected to the inner air guide hood connection port 102a on the cover plate 102, and the open part on the side of the outer air guide hood 303 is connected to the outer air guide hood connection port 101a on the frame 101. Thus, when the rotary cylinder outlet 301b on the rotary cylinder 301 faces the inner air guide hood connection port 102a, the connection between the rotary cylinder 301 and the inner air guide hood 302 can be realized. When the rotary cylinder outlet 301b on the rotary cylinder 301 faces the outer air guide hood connection port 101a, the connection between the rotary cylinder 301 and the outer air guide hood 303 can be realized.

[0065] It is worth noting that, based on the connection between the window frame 1 and the outer air guide 303 through the outer air hood connection port 101a and the open position on the side of the outer air guide 303, the connection position between the outer air guide 303 and the rotating cylinder 301 is also the position of the outer air hood connection port 101a on the frame 101. That is, when the rotating cylinder 301 is in the second position, the outer wall of the rotating cylinder 301 can block the outer air hood connection port 101a, thereby cutting off the connection between the outer air guide 303 and the rotating cylinder 301.

[0066] In this embodiment, as an example, the inner air guide shroud 302 and the outer air guide shroud 303 can be made of injection-molded plastic parts, and the inner air guide shroud 302 and the outer air guide shroud 303 can be fixed to the window frame 1 by conventional screwing, snap-fitting or gluing.

[0067] In addition, besides positioning the air outlet 3031 on the outer air guide 303 at the bottom of the outer air guide 303, and ensuring that the air outlet 3031 faces downwards and points towards the vehicle window 2, of course, it is still as follows... Figure 5 As shown, preferably, in a specific implementation, the air outlet of the inner air guide 302, that is, the air outlet 3021 of the inner air guide 302, can also be located at the bottom of the inner air guide 302, and the air outlet 3021 of the inner air guide 3021 can be directed downwards and towards the vehicle window glass 2. This also helps to allow the defogging airflow blown out by the inner air guide 302 to better defog the vehicle window glass 2.

[0068] In this embodiment, as follows... Figures 6 to 8 As shown, in some exemplary embodiments, the aforementioned rotating drum 301 may structurally include, for example, a drum body 3011, and mounting plates 3012 and end plates 3013 respectively disposed at both ends of the drum body 3011.

[0069] The cylindrical body 3011 serves as the main body of the rotating cylinder 301. A rotating cylinder outlet 301b is provided on one side of the cylindrical body 3011, extending axially. Simultaneously, two opposing rotating cylinder inlets 301a are provided at both ends of the cylindrical body 3011. These inlets 301a at each end facilitate communication between the rotating cylinder 301 and the inner cavity 1a of the window frame 1 when the rotating cylinder 301 is in its first and second positions, respectively. Therefore, when the rotating cylinder 301 is installed in the window frame 1, a connected airflow path can be formed between the fan assembly 306, the window frame 1, and the rotating cylinder 301 using the fan connection port 1b on the frame 101, the inner cavity 1a of the window frame 1, and the rotating cylinder inlets 301a at both ends of the cylindrical body 3011.

[0070] The aforementioned end plate 3013 is circular and is adapted to the inner diameter of the cylinder 3011. In specific implementation, the end plate 3013 at each end is mainly used to support both ends of the cylinder 3011, so as to cooperate with the mounting plate 3012 to realize the rotation setting of the rotating cylinder 301 in the window frame 1.

[0071] The aforementioned mounting plate 3012 is mainly used to install the rotating cylinder 301 in the window frame 1. In specific implementation, the two ends of the cylinder 3011 can be rotatably connected to the mounting plate 3012 at the same end through the rotating shaft in the middle of the end plate 3013. The mounting plates 3012 at each end can be fixed in the window frame 1 by screwing, snapping or other means, and are specifically connected to the frame 101 in the window frame 1.

[0072] In this embodiment, please refer to Figure 6 and Figure 8 As shown, in some exemplary embodiments, the heating assembly 304 may include, for example, an electric heater 3041 disposed within a rotating drum 301, and an electrical connector 3042 connected to the electric heater 3041 may be disposed at one end of the rotating drum 301. The electrical connector 3042 is adapted to connect to an external power supply device (i.e., vehicle power supply) to supply power to the electric heater 3041 when needed to realize its heating function.

[0073] The heating assembly 304 uses an electric heater 3041 installed inside the rotating drum 301, and the electric heater 3041 is connected to an external power supply device through an electrical connector 3042 located at one end of the rotating drum 301. It is understandable that this has the advantages of simple structure, mature technology, and easy installation inside the rotating drum 301. At the same time, the use of electric heating method, which has the characteristics of high efficiency, obviously also helps to ensure the heating effect of the demisting airflow entering the rotating drum 301.

[0074] In specific implementation, it is worth noting that the electric heater 3041 can be a suitable product that can be installed inside the rotating drum 301, and the electrical connector 3042 can also be a suitable structure that can realize the electrical connection between the electric heater 3041 and the external power supply device. It should also be noted that the design of the electrical connector 3042 should take into account the influence of the rotation of the rotating drum 301 in order to avoid interference between the connection of the electrical connector 3042 and the rotation of the rotating drum 301.

[0075] As an example, referring to common electrical connection methods on existing rotating parts, the aforementioned electrical connector 3042 can, for example, be a conductive ring disposed at one end of the rotating drum 301. There are two conductive rings, and each is electrically connected to a corresponding wire harness via a carbon brush. The wire harness is then electrically connected to an external power supply device. In addition to using conductive rings, since the rotating drum 301 in this embodiment generally reciprocates within a set angle, the aforementioned electrical connector 3042 can also, for example, be a wire harness disposed at one end of the rotating drum 301 and directly connected to the electric heater 3041. The wire harness has an appropriate length allowance at the end of the rotating drum 301 to avoid affecting the normal rotation of the rotating drum 301.

[0076] In this embodiment, as follows... Figures 1 to 3 and combined Figure 6 and Figure 8 As shown, in some exemplary embodiments, the drive assembly 305 may include, for example, a motor 3051 mounted on the window frame 1, and a transmission unit disposed between the motor 3051 and the rotating drum 301, through which the motor 3051 drives the rotating drum 301 to rotate. In this case, using a motor 3051 and a transmission unit connecting the motor 3051 and the rotating drum 301 in the drive assembly 305 has the advantages of simple structure and ease of design and implementation, while also helping to reduce the development and manufacturing costs of the drive assembly 305.

[0077] In specific implementations, in some exemplary embodiments, the aforementioned transmission unit may include, for example, a first transmission gear 3052 disposed on the power output end of the motor 3051 and a second transmission gear 3053 disposed at one end of the rotating drum 301, and the first transmission gear 3052 and the second transmission gear 3053 are meshed and connected.

[0078] Therefore, by using the meshing first transmission gear 3052 and second transmission gear 3053 in the above-mentioned transmission part, it also has the advantages of simple structure and convenient design and assembly of transmission part. At the same time, it obviously helps to control the transmission ratio of the transmission part located between the motor 3051 and the rotating drum 301, which is conducive to ensuring the stability of the motor 3051 driving the lower rotating drum 301 to rotate.

[0079] Furthermore, in specific implementation, it is worth noting that the first transmission gear 3052 is generally directly connected to the power output end of the motor 3051, that is, connected to the output shaft of the motor 3051. The second transmission gear 3053 can be connected to the shaft on the end plate 3013 at one end. The motor 3051 is generally located on the outside of the window frame 1 and can be fixed to the window frame 1 by conventional screw connections, etc. The output shaft of the motor 3051 can be inserted into the window frame 1 through the through hole on the frame 101.

[0080] It is worth noting that, regarding the window assembly of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 8 As shown, it may include, for example, a window frame 1 with a window glass 2 and a defogging structure 3 disposed on the window frame 1.

[0081] The defogging structure 3 includes a rotating cylinder 301 mounted on the window frame 1, a drive assembly 305 connected to the rotating cylinder 301, an inner air guide hood 302 and an outer air guide hood 303 mounted on opposite sides of the window frame 1, a fan assembly 306 mounted on the frame 1, and a heating assembly 304 mounted inside the rotating cylinder 301.

[0082] The rotating drum 301, along with the inner air guide shroud 302 and the outer air guide shroud 303, are located at the top of the frame 1, while the fan assembly 306 is located at the bottom of the frame 1. Furthermore, the rotating drum 301 is also located inside the frame 1, and the air outlet of the fan assembly 306 is connected to the inside of the rotating drum 301 through the inner cavity of the frame 1. Simultaneously, the air inlet of the fan assembly 306 is located on the inner side of the frame 1.

[0083] Furthermore, the heating assembly 304 includes an electric heater 3041 disposed within the rotating drum 301, and an electrical connector 3042 connected to the electric heater 3041 is provided at one end of the rotating drum 301. The drive assembly 305 includes a motor 3051 disposed on the frame 1, and a transmission part disposed between the motor 3051 and the rotating drum 301. Simultaneously, driven by the drive assembly 305, the rotating drum 301 can be in a first position communicating with the inner air guide shroud 302, or a second position communicating with the outer air guide shroud 303.

[0084] When the rotating drum 301 is in the first position, the defogging airflow inside the rotating drum 301 is heated by the heating component 304 and then blown towards the inside of the window glass 2 through the inner air guide 302. When the rotating drum 301 is in the second position, the defogging airflow inside the rotating drum 301 is heated by the heating component 304 and then blown towards the outside of the window glass 2 through the outer air guide 303.

[0085] In the preferred embodiment of the above-mentioned window assembly, the specific configuration and arrangement of the rotating cylinder 301, inner and outer air guides, heating components 304, driving components 305 and fan components 306 in the window frame 1 and the defogger structure 3 can still be referred to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the rotating cylinder 301, inner and outer air guides, heating components 304, driving components 305 and fan components 306 in the window frame 1 and the defogger structure 3 can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0086] Moreover, taking the window assembly in the above preferred embodiment as an example, and taking the window assembly as the rear windshield of the vehicle as an example, in specific implementation, the heating component 304, the drive component 305 and the fan component 306 in the defogger structure 3 can generally be connected to the vehicle controller in the vehicle. At the same time, physical or virtual control buttons for controlling the defogger structure 3 can be set on the vehicle's dashboard or in the vehicle's central control screen.

[0087] The aforementioned buttons may include, for example, "interior defogger" and "exterior defogger." "Interior defogger" means defogging the inside of the window glass 2, and similarly, "exterior defogger" means defogging the outside of the window glass 2. In this way, when the driver notices fogging on the rear window, that is, the window glass 2, he can operate the corresponding button on the instrument panel or the central control screen to select the interior defogger or the exterior defogger mode based on the actual situation.

[0088] In the internal defogging mode, the motor 3051 starts, connecting the rotary drum outlet 301b on the rotary drum 301 to the inner air guide shroud 302. Then, the electric heater 3041 is energized, and the fan assembly 306 starts, allowing a certain amount of defogging airflow to be blown into the inner side of the window glass 2 through the inner air guide shroud 302, thus achieving defogging. In the external defogging mode, the motor 3051 starts, connecting the rotary drum outlet 301b on the rotary drum 301 to the outer air guide shroud 303. Then, the electric heater 3041 is energized, and the fan assembly 306 starts, allowing a certain amount of defogging airflow to be blown into the outer side of the window glass 2 through the outer air guide shroud 303, thus achieving rapid defogging of the outer side of the window glass 2.

[0089] After defogging is completed at the rear windshield, i.e., at the two window glass locations, the driver can operate the corresponding button on the instrument panel or central control screen again to stop defogging. After defogging stops, preferably, for example, the rotary air outlet 301b on the rotary cylinder 301 can be kept in communication with the inner air guide 302, thereby cooperating with the sealing of the outer wall of the rotary cylinder 301 against the outer air guide 303 to prevent rainwater or car wash water from entering the window assembly.

[0090] The window assembly of this embodiment adopts the above design. By setting a defogging structure 3 on the window frame 1, it can not only use the heating component 304 to heat the defogging airflow entering the rotating cylinder 301 to achieve hot air defogging of the window glass 2, but also selectively defog the inner or outer side of the window glass 2 as needed. This can increase the defogging speed of the window glass 2, improve the defogging efficiency of the window, and help improve the overall quality of the vehicle.

[0091] An embodiment of the second aspect of this application provides a vehicle having a window assembly as described in the first aspect embodiment above.

[0092] In specific implementations, in some exemplary embodiments, the aforementioned window assembly can be, for example, the rear window of a vehicle. Therefore, by using the aforementioned window assembly for the rear window of a vehicle, efficient defogging of the window glass 2 constituting the rear window can be achieved, ensuring the driver has a clear rear view, reducing driving safety hazards caused by blurred vision, and improving the safety quality of the vehicle.

[0093] However, in addition to using the aforementioned window assembly for the rear window of the vehicle, it is also feasible to use the aforementioned window assembly for windows in other locations of the vehicle, or to use the aforementioned window assembly for both the rear window and windows in other locations of the vehicle. Those skilled in the art can make the choice based on specific design needs.

[0094] Furthermore, in some exemplary embodiments of this example, the aforementioned window assembly can be detachably installed in the vehicle body. In this case, detachably installing the window assembly in the vehicle body not only enables a modular design of the window assembly, facilitating its design, fabrication, and assembly within the vehicle body, but also obviously facilitates subsequent maintenance and repair.

[0095] As an example, continuing with the case where the aforementioned window assembly is the rear window of the vehicle, and the rear window is specifically located on the rear tailgate, the window assembly is installed in the vehicle body in a way that makes it detachable. For example, the window assembly can be detachably installed on the rear tailgate via the window frame 1, and the window frame 1 and the sheet metal structure of the rear tailgate can be fixed together by screws.

[0096] In addition to the window assembly being detachably mounted in the vehicle body, other exemplary embodiments, as mentioned in the first aspect embodiment, may also integrate the window assembly into the vehicle body.

[0097] The window assembly is integrated into the vehicle body, meaning the window frame 1 and the vehicle body are a single structure. Furthermore, taking the aforementioned window assembly as the rear window of the vehicle, specifically located on the tailgate, as an example, the window frame 1 and the vehicle body are a single structure. This means the window frame 1 can be constructed from the tailgate sheet metal structure, or it can be welded to the tailgate sheet metal to form a single structure.

[0098] The vehicle in this embodiment, by adopting the window assembly described above, can increase the defogging speed of the window glass, improve the defogging efficiency of the window, help improve driving safety, and thus enhance the overall quality of the vehicle.

[0099] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
