[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "outer surface", "inner surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0019] See also Figure 1 , Figure 2 and Figure 3 The present application provides a window assembly 100 for a vehicle, the window assembly 100 includes a vehicle window glass and a vehicle-mounted unit 30, the vehicle window glass includes a laminated glass 10 and a microstrip antenna 20. The laminated glass 10 has an outer surface 11 facing the outside of the vehicle and an inner surface 12 opposite to the outer surface 11. The microstrip antenna 20 is fixed between the outer surface 11 and the inner surface 12 or attached to the inner surface 12. The laminated glass 10 is provided with a vehicle-mounted unit connecting portion 13 on the inner surface 12, the vehicle-mounted unit connecting portion 13 is used to be fixedly connected to the vehicle-mounted unit 30, and the vehicle-mounted unit 30 is electrically connected to the microstrip antenna 20. It can be understood that the window assembly 100 can be applied to vehicle equipment such as cars, trucks, and buses, and the window assembly 100 can be a front windshield, a rear windshield, or a side window glass. The front windshield is preferred in this embodiment.

[0020] In this embodiment, the laminated glass 10 may be composed of multiple layers of glass stacked together. After the window assembly 100 is installed on a vehicle, the outer surface 11 is arranged toward the outside of the vehicle, and the inner surface 12 is arranged toward the inside of the vehicle. The outer surface 11 may be a curved surface convex outward, and the inner surface 12 is arranged substantially parallel to the outer surface 11. The laminated glass 10 may also be coated with a heat-insulating film on the inner surface 12 and the outer surface 11 to increase the heat-insulating performance of the laminated glass 10. The heat-insulating film is provided with a hollow hole in the film layer in the area facing the microstrip antenna 20, and the electromagnetic signal of the microstrip antenna 20 can be transmitted through the hollow hole in the film layer, thereby preventing the microstrip antenna 20 from being interfered by the heat-insulating film and improving the communication performance of the microstrip antenna 20. The laminated glass 10 may also be provided with a wire mesh between the inner surface 12 and the outer surface 11. When the wire mesh is energized, the wire mesh can heat the laminated glass 10, so that the laminated glass 10 is not easily frosted or fogged, thereby making the laminated glass 10 defrost and defog. The area of ​​the wire mesh facing the microstrip antenna 20 may be provided with a wire mesh hollow portion, and the electromagnetic signal of the microstrip antenna 20 can be transmitted through the wire mesh hollow portion, thereby preventing the microstrip antenna 20 from being interfered by the wire mesh and improving the communication performance of the microstrip antenna 20.

[0021] It is understandable that, since the microstrip antenna 20 can be integrated into the laminated glass 10, a avoidance structure can be set for the area where the laminated glass 10 has signal interference with the microstrip antenna 20, and the electromagnetic signal of the microstrip antenna 20 can be transmitted by the avoidance structure to prevent the signal of the microstrip antenna 20 from being interfered with, thereby increasing the communication performance of the microstrip antenna 20. That is, in this embodiment, the avoidance structure is not limited to the hollow holes of the film layer and the hollow parts of the wire mesh of the thermal insulation film.

[0022] In this embodiment, the microstrip antenna 20 is close to the edge of the laminated glass 10 to reduce the influence of the microstrip antenna 20 on the visible range of the laminated glass 10. The position where the microstrip antenna 20 is fixed to the laminated glass 10 can be adjusted according to the area of ​​the laminated glass 10 to meet the structural requirements of the window assembly 100, and can be adaptively adjusted according to a variety of different vehicle models. For example, when the visible range of the laminated glass 10 is large, the microstrip antenna 20 can be set at a distance from the edge of the laminated glass 10 to reduce the probability of the microstrip antenna 20 being interfered by the signal. When the visible range of the laminated glass 10 is small, the microstrip antenna 20 can be set at a distance from the edge of the laminated glass 10 to ensure that the visible range of the laminated glass 10 meets the requirements. When the window assembly 100 is applied to a vehicle, the microstrip antenna 20 can be set at the edge of the laminated glass 10 close to the roof to increase the communication range.

[0023] Specifically, the laminated glass 10 includes a first long side 14, a second long side 15 arranged relative to the first long side 14, and two opposite short sides 16. The two short sides 16 are connected between the first long side 14 and the second long side 15. The microstrip antenna 20 is arranged close to the first long side 14. The distance from the microstrip antenna 20 to the first long side 14 can be adjusted as needed to reduce the influence of the microstrip antenna 20 on the visible range of the laminated glass 10 and ensure the communication requirements of the microstrip antenna 20. It should be noted that the first long side 14 and the second long side 15 may not be equal, for example, the first long side is smaller than the second long side, but this is not limited to it.

[0024] In this embodiment, the on-board unit connection part 13 can stabilize the on-board unit 30 so that the on-board unit 30 is fixed on the window assembly 100. The position of the on-board unit connection part 13 on the inner glass can be adjusted as needed to facilitate the installation of the on-board unit 30 and the window assembly 100, and ensure the uniform adaptability of the on-board unit 30. The difference between the on-board unit 30 and the conventional on-board unit is that the on-board unit 30 is not provided with an antenna. The on-board unit 30 only needs to realize the reception and processing of the signal of the microstrip antenna 20 and send a response signal through the microstrip antenna 20. By integrating the microstrip antenna 20 into the laminated glass 10, the microstrip antenna 20 can be effectively arranged according to the structure of the laminated glass 10, thereby effectively improving the communication efficiency. The on-board unit connection part 13 and the on-board unit 30 can be fixedly connected by adhesive, or can be welded, or can be provided with a snap fastener for snap connection. The on-board unit connection part 13 is provided by utilizing the window assembly 100, so that the on-board unit 30 can be adapted to the window assembly 100 in a targeted manner, and a complete service chain of window glass, vehicle, on-board unit 30 and ETC (Electronic Toll Collection) can be provided to improve communication efficiency.

[0025] It is understandable that the vehicle-mounted unit 30 may be provided with a connector 31, a processor 32 and a circuit board 33. The connector 31 is electrically connected to the microstrip antenna 20 to transmit an electrical signal to the microstrip antenna 20 or receive an electrical signal from the microstrip antenna 20. The connector 31 and the microstrip antenna 20 may be directly electrically connected or coupled electrically connected. The processor 32 is electrically connected to the connector 31 to receive a data signal from the connector 31, and decodes the data signal to generate a decoding response signal. The processor 32 sends the decoding response signal to the microstrip antenna 20.

[0026] It can be understood that, on an ETC (Electronic Toll Collection) lane, when a vehicle equipped with a window assembly 100 integrated with the microstrip antenna 20 passes through the ETC lane, the RSU (Road Side Unit) of the ETC lane can send a radio frequency signal of a certain frequency to the microstrip antenna 20 of the window assembly 100 through the reader / writer via the antenna. After receiving the radio frequency signal, the microstrip antenna 20 transmits the radio frequency signal to the on-board unit 30 on the window assembly 100. After the on-board unit 30 on the window assembly 100 decodes the data signal, it sends its own coded response radio frequency signal through the microstrip antenna 20. The coded response radio frequency signal is acquired by the reader / writer of the RSU, and is decoded and sent to the data exchange and management system for processing to achieve automatic identity recognition. Of course, if the microstrip antenna 20 is a passive RF antenna, the microstrip antenna 20 may directly send a response RF signal after receiving the RF signal of the RSU, and the coded response RF signal is acquired by the reader of the RSU to realize automatic identity recognition.

[0027] For further information, see Figure 4 and 5 The laminated glass 10 includes an outer layer of glass 101 and an inner layer of glass 102 laminated with the outer layer of glass 101, the inner layer of glass 102 has a first surface 1021 facing the outer layer of glass 101 and a second surface 1022 away from the outer layer of glass, and a groove structure 1023 is arranged on the outer edge of the inner layer of glass. Preferably, the cross-sectional shape of the groove structure 1023 is a geometric structure that is wide in the middle and narrow on both sides. Specifically, the groove structure 1023 can be a crescent-shaped, bow-shaped or arc-shaped cylindrical groove, preferably a crescent-shaped. The distance D between the groove structure and the upper edge of the inner layer of glass is between 15 and 25 mm, and the corresponding diameter R of the partial arc segment in the crescent-shaped groove structure is between 120 and 150 mm.

[0028] In this embodiment, the outer layer of glass 101 and the inner layer of glass 102 are bent. The outer layer of glass 101 is substantially parallel to the inner layer of glass 102. The outer layer of glass 101 and the inner layer of glass 102 are both baked bent glass. That is, the inner layer of glass 102 and the outer layer of glass 101 can be bent and formed by a high-temperature baking process. The microstrip antenna 20 can be clamped between the outer layer of glass 101 and the inner layer of glass 102, or embedded in the outer layer of glass 101, with a distance from the outer surface of the outer layer of glass 101, or embedded in the inner layer of glass 102, or attached to the inner surface of the inner layer of glass 102. Of course, in other embodiments, the laminated glass 10 can also be provided with an intermediate layer of glass between the outer layer of glass 101 and the inner layer of glass 102, and the microstrip antenna 20 can also be clamped between the outer layer of glass 101 and the intermediate layer of glass, or clamped between the inner layer of glass 102 and the intermediate layer of glass.

[0029] Specifically, the laminated glass 10 further includes a plastic resin layer 103 bonded between the inner glass 102 and the outer glass 101. After the solid plastic resin layer 103 is laid on the outer glass 101, the inner glass 102 is bonded to the plastic resin layer 103, and finally the outer glass 101 and the inner glass 102 are pressed together by a hot pressing process, and the plastic resin layer 103, the outer glass 101 and the inner glass 102 are structurally stable, and finally the laminated glass 10 is obtained. Of course, in other embodiments, multiple layers of the plastic resin layer 103 may also be arranged between the inner glass 102 and the outer glass 101. Further, the plastic resin layer has a groove structure, and the position of the groove structure is consistent with the groove structure 1023 at the outer edge of the inner glass from a top view, and the shape and size of the groove structure are basically consistent with the groove structure 1023 at the outer edge of the inner glass.

[0030] In one embodiment, the microstrip antenna 20 is fixed between the outer glass 101 and the inner glass 102. The microstrip antenna 20 is embedded in the plastic resin layer 103. Specifically, after the plastic resin layer 103 is laid on the side of the outer glass 101 away from the outer surface, a receiving hole (not shown in the figure) is processed on the plastic resin layer 103, and the microstrip antenna 20 is placed in the receiving hole, and then the inner glass 102 is attached to the plastic resin layer 103, and the inner glass 102, the plastic resin layer 103 and the outer glass 101 are heat-pressed together.

[0031] In one embodiment, see Figure 4 and Figure 5The microstrip antenna 20 is fixed between the outer layer of glass 101 and the inner layer of glass 102, and the vehicle-mounted unit 30 is located on the second surface 1022 of the inner layer of glass 102. The microstrip antenna 20 is coupled and electrically connected with the vehicle-mounted unit 30. The coupling and electrical connection mode between the vehicle-mounted unit 30 and the microstrip antenna 20 is preferably a coaxial cable 40 coupling and electrical connection, mainly based on the consideration that the coaxial cable has strong anti-interference ability and good shielding performance. Specifically, a groove structure 1023 is provided at the outer edge of the inner layer of glass, and a part of the microstrip antenna provided between the outer layer of glass and the inner layer of glass extends until it is exposed to the groove structure 1023, and the packaging glue 50 is filled in the groove structure 1023, and a shielding body 60 is also provided between the microstrip antenna 20 exposed in the groove structure 1023 and the packaging glue 50, and the microstrip antenna 20 and the vehicle-mounted unit 30 are electrically connected through the coaxial cable 40. The material of the shielding body can be ABS (acrylonitrile-butadiene-styrene copolymer), PPS (polyphenylene sulfide), PBT (polybutylene terephthalate), PPO (polyphenylene oxide or polyphenylene ether), etc. The shielding body structure can be a cover plate or a film. In this embodiment, a film is selected as the shielding body, so that the film can directly wrap the part of the microstrip antenna 20 exposed to the groove structure and the one end connector 401 of the coaxial cable 40, and the packaging glue 50 wraps the film shielding body 60, so as to avoid direct contact between the packaging glue 50 and the exposed part of the microstrip antenna 20 and the one end connector of the coaxial cable 40, thereby playing an effective protective role.

[0032] Furthermore, the coaxial cable 40 passes through the groove structure 1023, wherein one end of the coaxial cable 40 is electrically connected to the microstrip antenna 20, and the other end is electrically connected to the vehicle-mounted unit 30. It should be noted that the groove structure 1023 is used as a receiving cavity to reserve space for welding the microstrip antenna and the coaxial cable, and the slotted structure of the plastic resin layer further increases the volume of the receiving cavity, which is conducive to increasing the working space when the coaxial cable is welded. The specific position of the vehicle-mounted unit 30 arranged on the second surface 1022 of the inner layer of glass 102 can be adjusted as needed, such as partially overlapping with the microstrip antenna in the horizontal projection direction, or completely avoiding the microstrip antenna, or being located in the upper edge area of ​​the inner layer of glass, so as to increase the visual range of the laminated glass 10.

[0033] Further, the microstrip antenna 20 may include a substrate, a radiator and a ground electrode. As a preferred embodiment, the thickness of the microstrip antenna 20 is less than or equal to the thickness of the plastic resin layer 103, which facilitates the embedding of the microstrip antenna 20 into the plastic resin layer 103, increases the stability of the substrate 21, and ensures the safety and reliability of the microstrip antenna 20. The welding form of the microstrip antenna 20 and the coaxial cable 40 can be flat welding or probe welding, and flat welding is preferred in this embodiment. After welding, the microstrip antenna and the coaxial cable are encapsulated with a packaging glue 50, and the packaging glue 50 fills the groove structure 1023. The packaging glue 50 can be a conductive material or an electrical insulating material. The electrical insulating material can be selected from polysiloxane, room temperature vulcanized polysiloxane, toughened epoxy resin, polyurethane (PU) glue, silicone, butyl synthetic rubber, dielectric grease and a combination thereof. If silicone is selected, its dielectric constant is about 3 and the loss tangent value is about 0.003.

[0034] In another embodiment, see Figure 6 and Figure 7 ,and Figure 4 and Figure 5The embodiments shown are roughly the same, except that the shielding body uses a cover plate to limit the formation of a cavity structure between the packaging glue and the microstrip antenna exposed in the groove structure. The dielectric constant of the cover shielding body is smaller than the dielectric constant of the packaging glue. If the packaging glue uses silicone with a dielectric constant of about 3, the material of the cover is preferably an injection molding material with a dielectric constant less than 3, such as: ABS (acrylonitrile-butadiene-styrene copolymer), PPS (polyphenylene sulfide), PBT (polybutylene terephthalate), PPO (polyphenylene oxide or polyphenylene ether), etc. Generally speaking, the frequency of ETC communication signals is around 5.8 GHz, which is a high-frequency signal. The higher the frequency of the electromagnetic wave and the shorter the wavelength, the worse the diffraction ability, and the greater the attenuation of the electromagnetic wave during propagation. During signal propagation, the larger the dielectric constant of the material around the antenna, the greater the impact on the electromagnetic signal, which will greatly weaken the electromagnetic signal. Generally, substances with a relative dielectric constant greater than 3.6 are polar substances; substances with a relative dielectric constant in the range of 2.8 to 3.6 are weakly polar substances; and substances with a relative dielectric constant less than 2.8 are non-polar substances. The dielectric constant of the encapsulation glue commonly used in vehicle glass encapsulation is generally a polar substance, which will cause adverse attenuation to the ETC communication signal. Therefore, this embodiment uses a cover plate with a low dielectric constant to define a cavity structure between the encapsulation glue and the microstrip antenna exposed in the groove structure, thereby isolating the microstrip antenna exposed in the groove structure from the encapsulation glue. The microstrip antenna exposed in the groove structure is surrounded by air substances with a dielectric constant of approximately 1, and the cover plate itself is also a low dielectric constant material, which can effectively avoid or reduce the weakening of the antenna signal. Compared with the technical solution of not using a cover plate shielding body and directly using encapsulation glue to encapsulate the microstrip antenna exposed in the groove structure, this embodiment can increase the gain by about 2db.

[0035] Furthermore, the shape and volume of the cover plate are preferably such that they can cover the part of the microstrip antenna exposed in the groove structure and facilitate packaging with packaging glue. From a top view, it can be rectangular, circular, elliptical or crescent-shaped. In this embodiment, a rectangular shape is selected. If the volume of the shielding body is too small (less than 5%), it is not conducive to the formation of a cavity; if the volume of the shielding body is too large (greater than 95%), it is not conducive to the filling of the packaging glue. Therefore, the volume of the cover shielding body accounts for 5% to 35% of the volume of the groove structure, or 35% to 65%, or 65% to 95%. In this embodiment, the volume of the cover shielding body accounts for 5% to 35% of the volume of the groove structure. An adhesive (not shown in the figure) is first used to fix it on the exposed glass in the groove structure, and then the packaging glue is used for packaging. The adhesive can be selected from ultraviolet light curing glue, reactive polyurethane hot melt glue, epoxy glue, acrylate glue, polyurethane glue, etc. In this embodiment, ultraviolet light curing glue is preferred, which has the advantages of fast curing speed and high operability.

[0036] Further, the height of the encapsulant 50 filled in the groove structure is substantially flush with the height of the second surface 1022 of the inner glass 102, that is, the height of the encapsulant 50 in the groove structure can be substantially flush with the height of the second surface 1022 of the inner glass 102, or the height of the encapsulant 50 is slightly higher than the height of the second surface 1022, or the height of the encapsulant 50 is slightly lower than the height of the second surface 1022. Optionally, refer to Figure 6 In the groove structure, the distance from the upper edge of the inner glass layer is the height of the encapsulant D1, which is lower than the height of the second surface 1022 of the inner glass layer 102, and is used to reserve the edge strip for bonding the vehicle glass (edge ​​strip is not shown in the figure). The value of D1 can be determined according to the size of the groove structure, for example, between 5 and 10 mm.

[0037] In yet another embodiment, see Figure 8 ,and Figure 4 and Figure 5 The embodiment shown is roughly the same, except that the shape of the cover shielding body 60 of this embodiment is similar to the shape of the groove structure of the outer edge of the inner glass. When the groove structure is crescent-shaped, the shape of the cover shielding body 60 is preferably crescent-shaped accordingly. This embodiment uses a cover shielding body whose accommodation volume accounts for 65% to 95% of the volume of the groove structure, and more preferably 80 to 90%. Since the accommodation volume of the cover shielding body accounts for a large volume of the groove structure, it is convenient to position and not easy to shift. In this way, there is no need to first use an adhesive to fix the cover plate and then use a packaging glue to package it. Instead, the cover shielding body and the groove structure can be directly filled and packaged with a packaging glue, that is, the process steps of using an adhesive can be omitted, the process flow can be simplified, and the cost can be reduced. In summary, the crescent-shaped cover plate can effectively protect the part of the microstrip antenna exposed to the groove structure, can reduce the use of packaging glue, reduce the packaging cost, and at the same time make the packaging effect better. After packaging, it does not affect the antenna performance, effectively ensuring the normal use of ETC.

[0038] See also Figure 1 and Fig. 9The embodiment of the present application also provides a vehicle 200, which includes the window assembly 100 and a vehicle body 210. The window assembly 100 is fixed to the vehicle body 210. The vehicle body 210 includes a chassis 211, a wheel assembly 212, a power mechanism and a housing 213. The wheel assembly 212 is rotatably connected to the chassis 211, and the power mechanism is installed on the chassis 211 to output torque power to the wheel assembly 212. The window assembly 100 can be used as a front window glass of the vehicle 200. The microstrip antenna 20 can be set at a position of the window assembly 100 near the roof of the vehicle 200. The vehicle 200 also includes a vehicle-mounted unit 30, and the vehicle-mounted unit 30 is provided with a circuit board 33, and the vehicle-mounted unit 30 is fixed to the inner surface 12 of the laminated glass 10, and the circuit board 33 is electrically connected to the microstrip antenna 20.

[0039] In summary, the microstrip antenna 20 is fixed between the outer glass and the inner glass of the laminated glass 10, a groove structure 1023 is provided at the outer edge of the inner glass, a portion of the microstrip antenna extends until it is exposed in the groove structure, the packaging glue is filled in the groove structure 1023, and a shielding body 60 is also provided between the microstrip antenna 20 exposed in the groove structure 1023 and the packaging glue 50, and the microstrip antenna 20 and the vehicle-mounted unit 30 are electrically connected through the coaxial cable 40. The shielding body can effectively protect the microstrip antenna part exposed in the groove structure, and isolate the microstrip antenna exposed in the groove structure from the packaging glue, so that the antenna performance is not affected after packaging, and the normal use of ETC can be effectively guaranteed.

[0040] The above is an implementation method of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
