Description

Technical Field

[0001] This invention relates to the field of antenna technology, and more specifically, to a transparent antenna, automotive glass, and a vehicle scheduling method. Background Technology

[0002] Most conventional car antennas use whip antennas. Whip antennas are exposed to the elements for extended periods, making them susceptible to damage from external forces. Furthermore, corrosion can cause poor contact, leading to a decline in communication signal quality. Therefore, existing technology employs a printed antenna, which is made by mixing silver powder and resin to form a silver paste, which is then printed onto the rear windshield to create a printed antenna for use with car radios and other signal receivers. While this printed antenna addresses some of the shortcomings of existing whip antennas, it still presents the following problems:

[0003] 1. Because the printed antenna is installed on the rear windshield, the signal line connecting to the receiver must be painstakingly run through the vehicle's interior trim, which is extremely inconvenient in the production process and results in low assembly efficiency.

[0004] 2. The transmission characteristics of signals dictate that the greater the distance, the greater the loss will be. Therefore, the existing method of setting printed antennas on the rear windshield makes it difficult to control the signal transmission quality, whether in terms of signal strength or stability, resulting in poor sound reception quality.

[0005] 3. Due to the different vehicle types, some vehicles have a slanted rear windshield, while others have a nearly vertical one. When the printed antenna is installed on a nearly vertical rear windshield, if the location of the base station or relay station transmitting the signal source is exactly in line with the vertical plane of the printed antenna while the vehicle is in motion, due to the characteristics of radio frequency polarization waves, the strength of the received signal will be so weak that it will be impossible to receive the sound clearly, thus preventing the printed antenna from performing to its full potential.

[0006] On the other hand, if some of the printed antennas are mechanically mounted directly on the windshield, the non-transparent nature of the printed antennas in the existing technology will obstruct the driver's view and compromise driving safety. Summary of the Invention

[0007] In view of this, the present invention provides a transparent antenna, automotive glass, and vehicle scheduling method, which is easy to install on the windshield of a vehicle, facilitates the assembly of vehicle signal lines, and does not affect the driver's driving vision.

However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details described, or other methods, materials, apparatus, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring aspects of this disclosure. The same reference numerals in the figures denote the same or similar structures, and therefore their detailed descriptions are omitted.

[0034] like Figure 1 As shown, an embodiment of the present invention discloses a transparent antenna 302. The transparent antenna 302 includes a first protective layer 101, an antenna element 102, a base layer 103, a reflective layer 104, and a second protective layer 105, which are sequentially stacked. The base layer 103 is made of fluoropolymer resin. In this application, the fluoropolymer resin used has a light transmittance of ≥95%. Due to the high light transmittance of the fluoropolymer resin, high light transmittance of the transparent antenna 302 can be achieved, so that when the transparent antenna 302 is installed on the windshield of a vehicle, it will not affect the driver's visibility.

[0035] The first protective layer 101 and the second protective layer 105 are used to provide insulation and structural support for the transparent antenna 302. This application does not limit the material of the first protective layer 101 and the second protective layer 105. In a preferred embodiment, the first protective layer 101 and the second protective layer 105 can be made of fluoropolymer resin, which helps to enhance the transparency of the transparent antenna 302.

[0036] like Figure 2As shown in this application, the antenna element 102 is formed by arranging multiple etched antenna components 201, each antenna component 201 including a feed line 202 and an even number of antenna elements 203. Two antenna elements 203 are connected by the feed line 202. The even number of antenna elements 203 are symmetrically distributed about the feed line 202. The antenna elements 203 can be symmetrically distributed about the feed line 202 along a first direction or along a second direction. The first direction can be the direction of extension of the arrangement of the antenna elements 203. The first direction is perpendicular to the second direction. The transparent antenna 302 composed of antenna components 201 arranged in the above manner has a high communication signal strength, which is beneficial to improving the communication signal quality of the transparent antenna 302. For example, Figure 2 Each antenna assembly 201 contains four antenna elements 203.

[0037] The transparent antenna 302 can be installed on the windshield, rear windshield, or side windows of a vehicle. The transparent antenna 302 can also be used to manufacture V2V antennas, GPS antennas, or millimeter-wave antennas. This application does not limit the application of the transparent antenna 302. When installed on the windshield, it facilitates the connection of signal lines for equipment such as a front-side radio inside the vehicle, and does not obstruct the driver's view, thus ensuring driving safety.

[0038] In this embodiment, the reflective layer 104 at least covers the antenna assembly 201. The reflective layer 104 is formed by etching a conductive plate, resulting in an etched area and an unetched area. The unetched area forms the reflective layer 104. Specifically, the conductive plate is etched to obtain a reflective main body. The reflective main body forms the reflective layer 104. The area where the reflective main body is located is also the unetched area. The area where the reflective main body is located at least covers the antenna assembly 201, meaning the unetched area of ​​the conductive plate at least covers the antenna assembly 201. This helps to increase the signal strength reflected or received by the transparent antenna 302.

[0039] The aforementioned etched area refers to the region where the conductive plate has had its metal removed. In this embodiment, the etched area of ​​the conductive plate is provided with a heat insulation layer. This heat insulation layer may include a transparent conductive oxide layer, so that when the transparent antenna 302 is installed on the windshield of a vehicle, the light transmittance of the windshield is not affected, nor is the driver's visibility affected. That is, the heat insulation layer and the aforementioned reflective main body are disposed in the same layer of the aforementioned reflective layer 104, so that the automotive glass with the transparent antenna 302 installed achieves a heat insulation effect without significantly increasing the thickness of the transparent antenna 302.

[0040] In this embodiment, the thickness of the antenna element 102 is less than or equal to 10 nm, and the thickness of the substrate layer 103 is 20 μm to 150 μm. This facilitates the reduction of the thickness of the transparent antenna 302.

[0041] In another embodiment of this application, based on the above embodiment, the etched area of ​​the conductive plate is further provided with an explosion-proof film. The heat insulation layer, the explosion-proof film and the above-mentioned reflective main body are disposed on the same layer of the above-mentioned reflective layer 104, and the projection areas of the three on the first protective layer 101 of the transparent antenna 302 do not overlap. In this way, while ensuring that the transparent antenna 302 meets the usage requirements, the thickness of the transparent antenna 302 will not be significantly increased, which is beneficial to reducing the thickness of the transparent antenna 302.

[0042] An explosion-proof film is installed inside the transparent antenna 302, that is, an explosion-proof film is installed between the two layers of glass in the car. When it is impacted, it can absorb most of the energy and maintain the integrity of the glass. When the glass breaks, the explosion-proof film has adhesive force and high-strength toughness, which can keep the glass fragments from scattering, thus improving safety.

[0043] In another embodiment of this application, based on the above embodiments, the antenna element 102 is made of graphene. This is beneficial for enhancing the thermal conductivity of the transparent antenna 302 after it is powered on, enabling the transparent antenna 302 to heat up quickly. This is beneficial for the rapid defogging and defrosting of automotive glass when the transparent antenna 302 is applied to automotive glass.

[0044] In another embodiment of this application, based on the above embodiment, the transparent antenna 302 further includes a signal circuit. Each antenna component 201 in the antenna element 102 of the transparent antenna 302 has a lead-out portion, which is electrically connected to the signal circuit. The signal circuit has a first terminal and a second terminal. The antenna component 201 located in the first side region is electrically connected to the first terminal via a first signal line, and the antenna component 201 located in the second side region is electrically connected to the second terminal via a second signal line. The output directions of the first signal line and the second signal line are opposite. In the prior art, leading out the antenna signal line can easily damage the signal line, causing the antenna to be unable to receive data, resulting in the interruption or failure of ongoing ETC (Electronic Toll Collection) transactions. This technical solution ensures that even if one end of the signal line has a problem, the other end can still be powered on and used normally, without affecting the driver's experience.

[0045] In a preferred embodiment of this application, based on the above embodiments, the reflective layer 104 is made of graphene. This further enhances the thermal conductivity of the transparent antenna 302, enabling it to heat up quickly. This is beneficial for the rapid defogging and defrosting of automotive glass after the transparent antenna 302 is applied to it.

[0046] In a preferred embodiment of this application, based on the above embodiments, a visible light anti-reflection film is provided between the antenna components 201 in the antenna vibrator 102. Because the area between the antenna components 201 is the area after the metal has been etched away, providing a visible light anti-reflection film in this area allows interference of wavelengths within a specific range to occur without increasing the thickness of the transparent antenna 302. This reduces the intensity of reflected light, maximizes the transmission of visible light, and improves the transmission effect of the transparent antenna 302 when mounted behind the car window, further improving visibility while driving.

[0047] It should be noted that the antenna components constituting the antenna vibrator in this application can be obtained by etching metal foil such as copper foil, or by sputtering a metal coating on a fluororesin film using magnetron sputtering and then etching the metal coating; they can also be fabricated by screen printing silver paste on a fluororesin film, or by electric field-driven jet deposition micro-scale 3D printing on a fluororesin film. This application does not impose any limitations on these methods.

[0048] Another embodiment of the present invention discloses an automotive glass. The automotive glass includes an electric heating element 303 and a transparent antenna 302 disclosed in any of the above embodiments. The automotive glass is a laminated glass. The laminated glass includes a first glass panel, an intermediate layer 301, and a second glass panel stacked sequentially. The transparent antenna 302 and the electric heating element 303 are disposed in the same layer on the intermediate layer 301. Furthermore, the transparent antenna 302 and the electric heating element 303 do not overlap, which helps to save internal space in the automotive glass and reduce the thickness of the intermediate layer 301.

[0049] Because the ETC antenna is relatively thick, the intermediate layer 301 in this application is equipped with an ETC antenna, which is respectively located between two adjacent antenna assemblies 201. This satisfies the requirement to install the ETC antenna on the car glass while reducing the thickness of the transparent antenna 302 and making effective use of the internal space of the transparent antenna 302, that is, reducing the thickness of the intermediate layer 301 of the car glass.

[0050] In this embodiment, the material of the antenna vibrator 102 in the transparent antenna 302 of the car glass is graphene, and / or the material of the reflective layer 104 is graphene. This is beneficial to enhance the thermal conductivity of the transparent antenna 302 after it is powered on, so that the transparent antenna 302 can be heated quickly. This is beneficial to the car glass being able to quickly defrost and defog after the transparent antenna 302 is applied to the car glass.

[0051] Because infrared light needs to pass through the car glass to be received by the infrared camera after it is installed on the inner surface of the car glass, conventional laminated glass in the prior art can obstruct the transmission of infrared light, thus affecting the normal operation of the infrared camera. Furthermore, the metal film or transparent conductive oxide film layer within the transparent antenna 302 has infrared reflective properties, further increasing the obstruction of infrared light by the car glass.

[0052] Therefore, in this application, the reflective layer 104 of the transparent antenna 302, excluding the area where the reflective main body is located, is provided with an infrared anti-reflection film, that is, an infrared anti-reflection film is provided in the etched area. An infrared camera is provided on the inner surface of the first glass panel, and the infrared camera faces the infrared anti-reflection film. After the automotive glass is installed in the vehicle, the first glass panel faces the interior of the vehicle, and the inner surface of the first glass panel is the side facing the interior of the vehicle. This allows the automotive glass to meet the communication requirements of the infrared camera and improves the testing accuracy of the infrared camera.

[0053] In a preferred embodiment of this application, based on the above embodiments, as follows: Figure 3 As shown, the transparent antenna 302 has a first layout pattern formed by multiple first branches, and the electric heating element 303 has a second layout pattern formed by multiple second branches. The first branches and the second branches are spaced apart and parallel to each other, so that the first layout pattern and the second layout pattern are interlocked and formed in the intermediate layer 301. This allows for effective reuse of the space in the intermediate layer 301, which is beneficial for reducing the thickness of the intermediate layer 301.

[0054] In a preferred embodiment of this application, based on the above embodiments, a reflective film is provided in the layer containing the antenna element 102 of the transparent antenna 302 in the laminated glass, and a plurality of through holes are formed in the transparent antenna 302. These through holes extend from the side end face of the transparent antenna 302 closest to the vehicle interior to the reflective film. Therefore, after the automotive glass is installed for the side window of a vehicle, a one-way reflective film can be formed in the side window. That is, after etching, the antenna element 102 also has etched and unetched areas; the unetched area of ​​the antenna element 102 forms the antenna element 102 itself. The etched area of ​​the antenna element 102 is provided with the reflective film. This helps protect the privacy of vehicle users and improves their experience.

[0055] In a preferred embodiment of this application, based on the above embodiments, the electric heating element 303 is the transparent antenna 302, that is, the electric heating element 303 and the transparent antenna 302 are the same product. This means that directly using the transparent antenna 302 for heating instead of the electric heating element 303 can save on the number of components used and simplify the assembly process of automotive glass; furthermore, it reduces the obstruction of the electric heating element 303 to the light transmittance of the automotive windshield, which is beneficial to enhancing the transparency of the automotive windshield.

[0056] Another embodiment of the present invention discloses a vehicle. The vehicle is equipped with the automotive glass disclosed in any of the above embodiments. The vehicle includes a path selection module. The path selection module is connected to the transparent antenna 302 and the electric heating element 303 respectively, and the path selection module supplies power to the transparent antenna 302 and the electric heating element 303 in a time-sharing manner. Specifically, exemplarily, the path selection module may include a first control switch and a second control switch. The first control switch is used to control the power on and power off of the electric heating element 303. The second control switch is used to control the power on and power off of the transparent antenna 302. When the first control switch is on, the second control switch is off. Since the electric heating element 303, when heating, will negatively affect the communication signal quality of the transparent antenna 302, this application temporarily shuts down the transparent antenna 302 when the electric heating element 303 is heating, to avoid causing a poor user experience.

[0057] The aforementioned vehicle also includes windshield wipers. The aforementioned electric heating element 303 is the aforementioned transparent antenna 302, and the density of the transparent antenna 302 arranged in the windshield wiper projection area of ​​the intermediate layer 301 of the automotive glass is greater than the density of the transparent antenna 302 arranged in the non-windshield wiper projection area. The aforementioned windshield wiper projection area is the area corresponding to the orthographic projection on the automotive glass when the windshield wiper is working. The non-windshield wiper projection area is the area on the automotive glass other than the aforementioned windshield wiper projection area. This can prevent the windshield wipers from freezing to the windshield due to low temperatures in cold weather, thus preventing the windshield wipers from working properly. Furthermore, it is not necessary to set up a dedicated electric heating element 303 for heating; the transparent antenna 302 can be used directly for heating.

[0058] In a preferred embodiment of this application, based on the above embodiments, a conductive film layer is provided in the wiper projection area of ​​the intermediate layer 301 of the automotive glass. The conductive film layer is disposed between adjacent antenna components 201 of the antenna vibrator 102 in the transparent antenna 302. This can further improve the heating effect of the windshield wipers when they are frozen to the windshield in cold weather, without increasing the thickness of the transparent antenna 302 and effectively utilizing the internal space of the transparent antenna 302.

[0059] Another embodiment of the present invention discloses a vehicle control method for controlling a vehicle disclosed in any of the above embodiments, wherein the windshield and rear windshield of the vehicle are automotive glass disclosed in any of the above embodiments. The method includes the following steps:

[0060] S10, the vehicle receives driving parameters from the preceding vehicle via a transparent antenna in its windshield. At least some of the vehicle's driving parameters are adjusted based on the preceding vehicle's driving parameters, and the vehicle transmits its own driving parameters to the following vehicle via a transparent antenna in its rear windshield. This allows for direct communication between vehicles using transparent antennas within the car's windows, eliminating the need for base stations or other signal transmission intermediaries. This improves communication efficiency and speed, and enhances control accuracy when multiple vehicles are controlled simultaneously.

[0061] Specifically, all vehicles mentioned above, including the preceding vehicle, the vehicle itself, and the following vehicle, are driverless vehicles, and the aforementioned driving parameters may include vehicle speed, acceleration, and expected braking time, etc. This application is not limited thereto.

[0062] In practice, step S10 can be implemented through the following steps:

[0063] S101, obtain the real-time location of the vehicle, and establish a traffic flow group with the vehicle and a preset number of vehicles traveling in the same direction on the same road.

[0064] S102, the vehicles in the above-mentioned traffic flow group are sequentially combined in pairs to form multiple traffic flow pairs. Each traffic flow pair consists of two adjacent vehicles. The transparent antenna of the preceding vehicle serves as the transmitter, and the transparent antenna of the following vehicle serves as the receiver of the preceding vehicle and also as the transmitter of the next vehicle. The last vehicle in the above-mentioned traffic flow group serves as the receiver.

[0065] S103, in the above traffic flow group, two adjacent vehicles establish communication based on a transparent antenna.

[0066] In step S104, when a third vehicle is inserted between two vehicles in a traffic flow pair, it is determined whether the third vehicle belongs to the traffic flow group. If so, the transparent antenna of the third vehicle is used as the receiving end of the preceding vehicle in the traffic flow pair, and the communication between vehicles following the third vehicle in the traffic flow group is adjusted so that communication is re-established between every two adjacent vehicles in the traffic flow group based on the transparent antenna. Otherwise, no operation is performed, and step S104 is executed repeatedly.

[0067] This allows for timely and flexible adjustments to vehicle-to-vehicle communication via transparent antennas even after changes in the traffic flow group's arrangement, ensuring effective communication. The preset number can be set as needed, for example, to 5. A traffic flow group can consist of multiple vehicles traveling in the same direction on the same road with the same destination.

[0068] like Figure 4 As shown, another embodiment of the present invention discloses a vehicle scheduling method for scheduling vehicles disclosed in any of the above embodiments. The vehicle scheduling method includes the following steps:

[0069] S200 utilizes a transparent antenna inside the car window to set up a relay network, and obtains the location distribution information of all vehicles based on this transparent antenna. In other words, the location distribution information of vehicles can be obtained using the transparent antenna inside the car window, solving the problem that drivers may not turn on the network in real time due to concerns about mobile data charges, thus preventing the platform from obtaining the location distribution information of all vehicles in a timely manner. This eliminates the need to rely on the driver's mobile phone or other devices to obtain location information.

[0070] S300: Obtain a ride-hailing request submitted by a user device.

[0071] S400, based on the above-mentioned ride-hailing request and the above-mentioned location distribution information, matches a target vehicle for the user corresponding to the above-mentioned user equipment.

[0072] S500, when the target vehicle arrives at the user device's current location, controls the target vehicle's four turn signals and the user device's rear hazard lights to flash simultaneously. This allows both the driver and the user to quickly locate each other, improving the user experience.

[0073] Furthermore, the S600, after the user device enters the target vehicle and the target vehicle begins to depart, controls the user device to access the relay network corresponding to the transparent antenna inside the vehicle's window. This allows the user to directly access the internet through the relay network provided by the transparent antenna inside the vehicle after entering the target vehicle, eliminating the need to consume mobile data and improving the user experience.

[0074] It should be noted that all the embodiments disclosed above in this application can be combined in any way, and the resulting technical solutions are also within the protection scope of this application.

[0075] In summary, the transparent antenna, automotive glass, and vehicle scheduling method of the present invention have at least the following advantages:

[0076] The transparent antenna, automotive glass, and vehicle scheduling method disclosed in this embodiment enable the installation of an antenna inside the automotive glass, facilitating the installation of the antenna on the windshield of the vehicle. This facilitates the assembly of signal lines on the front side of the vehicle interior and does not affect the driver's visibility, thus ensuring driving safety.
