[0002] Generally, most of the automobile antennas are whip antennas. The whip antennas are exposed to the outside for a long time, are easily damaged by external forces, and are poor in contact after corrosion, resulting in a decline in communication signal quality. Therefore, a printed antenna is used in the prior art, which is made of silver powder and resin mixed into silver paste, and the silver paste is printed on the rear windshield to form a printed antenna for receiving signals of a car radio. This printed antenna solves some of the shortcomings of the existing whip antenna, but still has the following problems:

[0003] 1. The printed antenna is arranged on the rear windshield, so the signal line connected to the receiver must be carefully threaded through the interior decoration, which is extremely inconvenient in the production process, resulting in low assembly efficiency.

[0004] 2. The transmission characteristics of the signal determine that the farther the distance, the greater the loss. Therefore, the existing method of arranging the printed antenna on the rear windshield is difficult to control the signal transmission quality in terms of signal strength or stability, resulting in poor radio quality.

[0005] 3. Due to the difference in vehicle types, the rear windshield of some vehicles is inclined, and the rear windshield of some vehicles is nearly vertical. When the printed antenna is arranged on the nearly vertical rear windshield, and the direction of the base station or relay station of the signal source is in a straight line with the longitudinal plane of the printed antenna, the received signal strength will be weak and cannot be clearly heard due to the characteristics of radio frequency polarized waves, which affects the quality of the printed antenna.

[0006] On the other hand, if part of the printed antenna is directly mechanically arranged on the front windshield, since the printed antenna in the prior art is not transparent, it will hinder the driving vision of the vehicle driver, which is not conducive to driving safety. SUMMARY

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.

[0027] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including,” “having,” and “have” are used to indicate an open-ended inclusion meaning and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0028] 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.

[0029] 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.

[0030] like Figure 2As shown, in the present application, the antenna elements 102 are arranged by a plurality of etched antenna assemblies 201, each of which includes a feed line 202 and an even number of antenna units 203. Two antenna units 203 are connected by the feed line 202. The even number of antenna units 203 are symmetrically distributed about the feed line 202. The antenna units 203 can be symmetrically distributed about the feed line 202 in a first direction or in a second direction. The first direction can be the direction in which the antenna units 203 are arranged. The first direction is perpendicular to the second direction. The transparent antenna 302 arranged in the above form has high communication signal strength, which is beneficial to improve the communication signal quality of the transparent antenna 302. Exemplarily, Figure 2 Each of the antenna assemblies 201 includes four antenna units 203.

[0031] The transparent antenna 302 can be installed on the front windshield of a vehicle, or on the rear windshield, side window, etc. The transparent antenna 302 can also be used to make a V2V antenna, or a GPS antenna, or a millimeter wave antenna, etc. The application does not limit the use of the transparent antenna 302. When installed on the front windshield, it is convenient for the connection of the signal line when the front radio and other devices in the vehicle are assembled, and does not affect the driving field of view of the vehicle driver when driving, thereby ensuring driving safety.

[0032] In the present embodiment, the reflective layer 104 covers at least the antenna assembly 201. The reflective layer 104 is etched based on a conductive plate, and the conductive plate is etched to obtain 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 part. The reflective main body part forms the reflective layer 104. The area where the reflective main body part is located is the unetched area. The area where the reflective main body part is located covers at least the antenna assembly 201, i.e., the unetched area of the conductive plate covers at least the antenna assembly 201. This is beneficial to increase the signal strength reflected or received by the transparent antenna 302.

[0033] The etched area is the area where the metal of the conductive plate is etched. In the present embodiment, the etched area of the conductive plate is provided with a heat insulation layer. The heat insulation layer can include a transparent conductive oxide layer, so that when the transparent antenna 302 is arranged on the front windshield of a vehicle, the light transmittance of the front windshield is not affected, and the driving field of view of the vehicle driver is not affected. That is, the heat insulation layer and the reflective main body part are arranged in the same layer on the reflective layer 104, so that the automobile glass provided with the transparent antenna 302 achieves the effect of heat insulation without significantly increasing the thickness of the transparent antenna 302.

[0034] In the 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 20-150 μm. This is conducive to reducing the thickness of the transparent antenna 302.

[0035] In another embodiment of the present application, on the basis of the above embodiment, the etching area of the conductive plate is further provided with a blast-proof film, the blast-proof film, the heat insulation layer and the reflection main body part are arranged in the same layer as the reflection layer 104, and the projection areas of the three on the first protective layer 101 of the transparent antenna 302 do not overlap. This does not significantly increase the thickness of the transparent antenna 302 on the premise that the transparent antenna 302 meets the use requirements, and is conducive to reducing the thickness of the transparent antenna 302.

[0036] The blast-proof film is arranged inside the transparent antenna 302, that is, the blast-proof film is arranged between the two layers of glass of the automobile glass. When impacted, the blast-proof film can absorb most of the energy and maintain the integrity of the glass. When the glass is broken, the blast-proof film has adhesive force and high-strength toughness, and can keep the glass debris from scattering, thereby improving safety.

[0037] In another embodiment of the present application, on the basis of the above embodiment, the material of the antenna element 102 is graphene. This is conducive to enhancing the heat conduction performance of the transparent antenna 302 after the transparent antenna 302 is powered on, so that the transparent antenna 302 can be quickly heated, and the automobile glass can be quickly defrosted and defogged when the transparent antenna 302 is applied to the automobile glass.

[0038] In another embodiment of the present application, on the basis of the above embodiment, the transparent antenna 302 further includes a signal circuit. Each antenna assembly 201 in the antenna element 102 of the transparent antenna 302 has a lead-out part, and the lead-out parts are electrically connected to the signal circuit. The signal circuit has a first terminal and a second terminal. The antenna assemblies 201 located in the first side region are electrically connected to the first terminal through a first signal line, and the antenna assemblies 201 located in the second side region are electrically connected to the second terminal through a second signal line. The lead-out directions of the first signal line and the second signal line are opposite. In the prior art, the signal line of the antenna is easily damaged when the signal line is led out, which causes the antenna to be unable to receive data, resulting in interruption or failure of the ETC (Electronic Toll Collection) transaction being performed. The technical scheme can ensure that the other signal line can still be normally powered on when one end of the signal line has a problem, and does not affect the use experience of the vehicle driver.

[0039] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, the material of the reflecting layer 104 is graphene. In this way, the heat conduction performance of the transparent antenna 302 can be further enhanced, so that the transparent antenna 302 can be quickly heated, which is beneficial to quickly defogging and defrosting of the automobile glass after the transparent antenna 302 is applied to the automobile glass.

[0040] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, a visible light anti-reflection film is arranged between the antenna components 201 in the antenna element 102. Because the area between the antenna components 201 is the area after etching away the metal, the visible light anti-reflection film arranged in this area can cause interference of a specific range of wavelengths without increasing the thickness of the transparent antenna 302, thereby reducing the intensity of reflected light, making the visible light be transmitted as much as possible, improving the transmission effect of the transparent antenna 302 after being installed on the automobile glass, and further improving the line of sight effect when driving.

[0041] It should be noted that the antenna components arranged to form the antenna element in the present application can be obtained by etching a metal foil such as a copper foil, or can be obtained by sputtering a metal plating layer on a fluororesin film by a magnetron sputtering method, and then etching the metal plating layer; can also be obtained by screen printing silver paste on a fluororesin film, or can be obtained by 3D printing in microscale by electric field driven jet deposition. The present application does not limit this.

[0042] Another embodiment of the present application discloses an automobile glass. The automobile glass comprises an electric heating element 303 and the transparent antenna 302 disclosed in any of the above-mentioned embodiments. The automobile glass is a laminated glass. The laminated glass comprises a first glass panel, an intermediate layer 301 and a second glass panel which are sequentially stacked. The transparent antenna 302 and the electric heating element 303 are arranged in the same layer in the intermediate layer 301. Moreover, the transparent antenna 302 and the electric heating element 303 do not overlap, which is beneficial to saving the internal space of the automobile glass and reducing the thickness of the intermediate layer 301 of the automobile glass.

[0043] Since the ETC antenna has a large thickness, the intermediate layer 301 in the present application is provided with an ETC antenna, and the ETC antenna is arranged between adjacent two antenna components 201. In this way, the thickness of the transparent antenna 302 can be reduced under the premise of meeting the need of installing the ETC antenna on the automobile glass, which is beneficial to effectively utilizing the internal space of the transparent antenna 302, i.e., reducing the thickness of the intermediate layer 301 of the automobile glass.

[0044] In the embodiment, the material of the antenna element 102 in the transparent antenna 302 of the automobile glass is graphene, and / or the material of the reflecting layer 104 is graphene, which is conducive to enhancing the heat conduction performance of the transparent antenna 302 after the transparent antenna 302 is powered on, so that the transparent antenna 302 can be quickly heated, and it is conducive to the automobile glass being able to quickly defogging, defrosting and the like after the transparent antenna 302 is applied to the automobile glass.

[0045] Since the infrared camera is installed on the inner surface of the automobile glass, the infrared rays need to pass through the automobile glass to be received by the infrared camera. The conventional laminated glass in the prior art will hinder the transmission of infrared rays, thereby affecting the normal work of the infrared camera. Moreover, the metal film layer or the transparent conductive oxide film layer in the transparent antenna 302 has the characteristic of reflecting infrared rays, so that the automobile glass hinders the infrared rays more.

[0046] Therefore, in the present application, the area of the reflecting layer 104 of the transparent antenna 302 except the area where the reflecting main body part is located is provided with an infrared anti-reflection film, that is, the infrared anti-reflection film is provided in the etched area. The inner surface of the first glass panel is provided with an infrared camera, and the infrared camera is opposite to the infrared anti-reflection film. Among them, after the automobile glass is installed on the vehicle, the first glass panel faces the inside of the vehicle, and the inner surface of the first glass panel is the side surface thereof facing the inside of the vehicle. In this way, the automobile glass can meet the communication requirements of the infrared camera and improve the test accuracy of the infrared camera.

[0047] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, as shown in Figure 3 The transparent antenna 302 has a first layout pattern formed by a plurality of first branches, and the electric heating element 303 has a second layout pattern formed by a plurality of second branches, the first branches and the second branches are spaced apart and parallel to each other, and the first layout pattern and the second layout pattern are embedded with each other to form the intermediate layer 301. In this way, the space of the intermediate layer 301 can be effectively reused, which is conducive to reducing the thickness of the intermediate layer 301.

[0048] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, a light-reflecting film is arranged in the layer of the transparent antenna 302 in which the antenna elements 102 are located in the above-mentioned laminated glass, and a plurality of through holes are formed in the transparent antenna 302, the through holes penetrating from the side end surface of the transparent antenna 302 close to the inside of the vehicle to the light-reflecting film, so that a one-way perspective light-reflecting film can be formed in the side window glass of the vehicle after the vehicle glass is installed as the side window glass of the vehicle. That is, after the etching of the antenna elements 102, there are also etched areas and unetched areas, and the unetched areas of the antenna elements 102 form the antenna elements 102. The etched areas of the antenna elements 102 are provided with the light-reflecting film. In this way, the privacy of the user of the vehicle is protected, and the experience of the user of the vehicle is improved.

[0049] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, 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. That is, the transparent antenna 302 is directly used for heating instead of using the electric heating element 303 for heating, which can save the number of components used and simplify the process assembly complexity of the vehicle glass; and the existence of the electric heating element 303 does not hinder the light transmittance of the front windshield of the vehicle, which is conducive to enhancing the transparency of the front windshield of the vehicle.

[0050] Another embodiment of the present application discloses a vehicle. The vehicle is installed with the vehicle glass disclosed in any of the above-mentioned embodiments. The vehicle comprises 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 at different times. Specifically, the path selection module can 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 turned on, the second control switch is turned off. Because the electric heating element 303 will have a negative impact on the communication signal quality of the transparent antenna 302 when it is working. Therefore, the transparent antenna 302 is temporarily turned off when the electric heating element 303 is working, so as to avoid causing the user to have a bad experience.

[0051] The vehicle further comprises a windshield wiper, the electric heating element 303 is the transparent antenna 302, and the density of the transparent antenna 302 arranged in the windshield wiper projection area of the middle layer 301 of the automobile glass is greater than the density of the transparent antenna 302 arranged in the non-windshield wiper projection area. The windshield wiper projection area is the area corresponding to the orthographic projection of the automobile glass when the windshield wiper is working. The non-windshield wiper projection area is the area of the automobile glass except the windshield wiper projection area. In this way, it can be avoided that the windshield wiper is frozen on the windshield of the vehicle in cold weather due to too low temperature, so that the windshield wiper cannot work normally. Moreover, it is not necessary to set a special electric heating element 303 for heating, and the transparent antenna 302 can be directly used for heating.

[0052] In a preferred embodiment of the present application, on the basis of the above-mentioned embodiment, the windshield wiper projection area of the middle layer 301 of the automobile glass is provided with a conductive film layer, and the conductive film layer is arranged between the adjacent antenna assemblies 201 of the antenna elements 102 in the transparent antenna 302. In this way, the heating effect of the windshield wiper when the windshield wiper is frozen on the windshield of the vehicle in cold weather can be further improved without increasing the thickness of the transparent antenna 302 and effectively utilizing the internal space of the transparent antenna 302.

[0053] Another embodiment of the present application discloses a control method of a vehicle, which is used for controlling the vehicle disclosed in any of the above-mentioned embodiments, and the front windshield and the rear windshield of the vehicle are the automobile glass disclosed in any of the above-mentioned embodiments. The method comprises the following steps.

[0054] S10, the vehicle receives the driving parameter of the front vehicle through the transparent antenna in the front windshield, at least part of the driving parameter of the vehicle is adjusted according to the driving parameter of the front vehicle, and the vehicle sends the driving parameter of the vehicle to the rear vehicle through the transparent antenna in the rear windshield. In this way, the communication between vehicles can be realized directly by using the transparent antenna in the automobile glass, without the need of using a base station as a signal transmission medium, which is beneficial to improve the communication efficiency and speed, and is beneficial to improve the control accuracy when a plurality of vehicles are controlled at the same time.

[0055] Specifically, all the vehicles including the front vehicle, the vehicle and the rear vehicle are unmanned vehicles, and the driving parameter can include the speed, the acceleration and the predicted braking time of the vehicle. The present application is not limited thereto.

[0056] In the implementation of the step S10, the following steps can be used:

[0057] S101, obtaining the real-time position of the vehicle, and establishing a vehicle flow group with a preset number of vehicles traveling in the same direction on the same road.

[0058] 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.

[0059] S103, in the above traffic flow group, two adjacent vehicles establish communication based on a transparent antenna.

[0060] 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.

[0061] 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.

[0062] 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:

[0063] 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.

[0064] S300: Obtain a ride-hailing request submitted by a user device.

[0065] S400, based on the above ride-hailing request and the above location distribution information, matches a target vehicle for the user corresponding to the above user device.

[0066] S500, when the target vehicle reaches the current location of the user equipment, controlling the four turn signals of the target vehicle and the rear flasher of the user equipment to flash simultaneously. In this way, the driver of the vehicle and the user of the user equipment can quickly find each other, thereby improving the user experience.

[0067] And S600, when the user corresponding to the user equipment enters the target vehicle, and the target vehicle starts to depart, controlling the user equipment to access the relay network corresponding to the transparent antenna in the car glass of the vehicle. In this way, after the user of the user equipment enters the target vehicle, the user can directly access the Internet through the relay network provided by the transparent antenna in the car, without consuming mobile network traffic, thereby improving the experience of the user of the user equipment.

[0068] It should be noted that all the embodiments disclosed in the present application can be combined in any way, and the technical solutions obtained by the combination are also within the protection scope of the present application.

[0069] In summary, the transparent antenna, the car glass and the control method of the vehicle of the present application have at least the following advantages:

[0070] The transparent antenna, the car glass and the control method of the vehicle disclosed in the embodiment realize the arrangement of the antenna in the car glass, facilitate the installation of the antenna on the front windshield of the vehicle, thereby facilitating the assembly of the signal line on the front side of the vehicle interior, and do not affect the driving field of view of the driver of the vehicle, thereby ensuring the driving safety.
