In other cases, known technical solutions are not shown or described in detail to avoid blurring various aspects of the present disclosure. The same reference numerals in the figures represent the same or similar structures, and thus their detailed descriptions will be omitted.

[0024] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including", "having" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0025] 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 vibrator 102, a base layer 103, a reflective layer 104 and a second protective layer 105 which are stacked in sequence. The base layer 103 is made of fluororesin. In the present application, the light transmittance of the fluororesin used is greater than or equal to 95%. Since the light transmittance of the fluororesin is relatively high, the transparent antenna 302 can be highly transparent, so that when the transparent antenna 302 is arranged on the front windshield of the vehicle, it will not affect the driving field of the vehicle driver.

[0026] The first protective layer 101 and the second protective layer 105 are used to achieve insulation and structural support effects for the transparent antenna 302. The present application does not limit the materials of the first protective layer 101 and the second protective layer 105. In a preferred embodiment, the materials of the first protective layer 101 and the second protective layer 105 can be fluororesin, which is conducive to enhancing the transparency of the transparent antenna 302.

[0027] like Figure 2 As shown, in the present application, the antenna vibrator 102 is formed by arranging a plurality of etched antenna components 201, and each antenna component 201 includes a feeder 202 and an even number of antenna units 203. Two antenna units 203 are connected via the feeder 202. The even number of antenna units 203 are symmetrically distributed about the feeder 202. Among them, the antenna units 203 can be symmetrically distributed about the feeder 202 along a first direction, or symmetrically distributed about the feeder 202 along a second direction. The first direction can be the arrangement extension direction of the antenna units 203. The first direction is perpendicular to the second direction. The transparent antenna 302 formed by the antenna components 201 arranged in the above manner has a higher communication signal strength, which is beneficial to improving the communication signal quality of the transparent antenna 302. By way of example, Figure 2 Each antenna assembly 201 includes four antenna units 203 .

[0028] The transparent antenna 302 can be installed on the front windshield of the vehicle, or on the rear windshield and side window glass. The transparent antenna 302 can also be used to make a V2V antenna, a GPS antenna, or a millimeter wave antenna. The present application does not limit the use of the transparent antenna 302. When installed on the front windshield, it is convenient to connect the signal line when assembling the front radio and other equipment in the vehicle, and it does not affect the driving field of the vehicle driver, thereby ensuring driving safety.

[0029] 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, and an etched area and an unetched area are obtained after etching the conductive plate. The unetched area forms the reflective layer 104. Specifically, a reflective main body is obtained after etching the conductive plate. 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, that is, the unetched area of ​​the conductive plate at least covers the antenna assembly 201. This is conducive to increasing the signal strength reflected or received by the transparent antenna 302.

[0030] The etched area is the area where the metal object is etched away on the conductive plate. In this embodiment, a heat insulating layer is provided in the etched area of ​​the conductive plate. The heat insulating layer may include a transparent conductive oxide layer, so that when the transparent antenna 302 is provided on the front windshield of the vehicle, the light transmittance of the front windshield is not affected, and the driving vision of the vehicle driver is not affected. That is, the heat insulating layer and the reflective main body are provided on the same layer of the reflective layer 104, so that the automobile glass provided with the transparent antenna 302 can achieve a heat insulating effect without significantly increasing the thickness of the transparent antenna 302.

[0031] In this embodiment, the thickness of the antenna element 102 is less than or equal to 10 nm, and the thickness of the base layer 103 is 20 μm to 150 μm, which is conducive to reducing the thickness of the transparent antenna 302 .

[0032] In another embodiment of the present application, based on the above embodiment, the etching area of ​​the above-mentioned conductive plate is also provided with an explosion-proof film, and the heat insulation layer, the explosion-proof film and the above-mentioned reflective main body are arranged in the same layer on 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 use requirements, the thickness of the transparent antenna 302 will not be significantly increased, which is conducive to thinning the thickness of the transparent antenna 302.

[0033] An explosion-proof film is set inside the transparent antenna 302, that is, an explosion-proof film is set between the two layers of automobile glass. When it is hit, it can absorb most of the energy and maintain the integrity of the glass. When the glass is broken, the explosion-proof film has adhesion and high-strength toughness, which can prevent the glass fragments from scattering, thereby improving safety.

[0034] In another embodiment of the present application, based on the above embodiment, the material of the antenna vibrator 102 is graphene. This is conducive to enhancing the thermal conductivity of the transparent antenna 302 after the transparent antenna 302 is powered on, so that the transparent antenna 302 can be quickly heated, which is conducive to the rapid defogging and defrosting of the automobile glass after the transparent antenna 302 is applied to the automobile glass.

[0035] 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 component 201 in the antenna vibrator 102 of the transparent antenna 302 has a lead-out portion, and the lead-out portion 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 area is electrically connected to the first terminal through a first signal line, and the antenna component 201 located in the second side area is electrically connected to the second terminal through a second signal line. The first signal line and the second signal line have opposite lead-out directions. Because in the prior art, the signal line of the antenna is easily damaged when it is led out, causing the antenna to be unable to receive data, resulting in the interruption or failure of the ongoing ETC (Electronic Toll Collection, electronic toll collection system) transaction. The use of this technical solution can ensure that after a problem occurs in the signal line at one end, the signal line at the other end can still be powered on and used normally, without affecting the user experience of the vehicle driver.

[0036] In a preferred embodiment of the present application, based on the above embodiment, the material of the reflective layer 104 is graphene. This can further enhance the thermal conductivity of the transparent antenna 302, so that the transparent antenna 302 can be quickly heated, which is beneficial for the automotive glass to be quickly defogged and defrosted after the transparent antenna 302 is applied to the automotive glass.

[0037] In a preferred embodiment of the present application, on the basis of the above embodiment, 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 is etched away, the visible light anti-reflection film is provided in this area, so that the wavelengths in a specific range can interfere without increasing the thickness of the transparent antenna 302, reducing the intensity of the reflected light, making the visible light as much as possible transmitted, and improving the transmission effect of the transparent antenna 302 after being installed on the car glass, and further improving the sight effect when driving.

[0038] It should be noted that the antenna assembly arranged to form the antenna vibrator in the present application can be obtained by etching a metal foil such as copper foil, or by sputtering a metal coating on a fluororesin film by magnetron sputtering, and then etching the metal coating; it can also be made by using a silver paste screen printing method on a fluororesin film, or by using an electric field driven jet deposition micro-scale 3D printing method on a fluororesin film. This application does not limit this.

[0039] Another embodiment of the present invention discloses a kind of automobile glass. The automobile glass comprises an electric heating element 303 and a transparent antenna 302 disclosed in any of the above embodiments. The above automobile glass is a laminated glass. The above laminated glass comprises a first glass panel, an intermediate layer 301 and a second glass panel stacked in sequence. The above transparent antenna 302 and the above electric heating element 303 are arranged in the same layer in the above intermediate layer 301. And the above transparent antenna 302 and the above electric heating element 303 do not overlap, which is conducive to saving the internal space of the automobile glass and reducing the thickness of the intermediate layer 301 of the automobile glass.

[0040] Since the thickness of the ETC antenna is relatively large, the intermediate layer 301 in the present application is provided with an ETC antenna, and the ETC antenna is respectively provided between two adjacent antenna components 201. In this way, while meeting the need to install the ETC antenna on the automobile glass, it is beneficial to reduce the thickness of the transparent antenna 302 and effectively utilize the internal space of the transparent antenna 302, that is, to reduce the thickness of the intermediate layer 301 of the automobile glass.

[0041] In the present 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 reflective layer 104 is graphene, which is beneficial for enhancing the thermal conductivity of the transparent antenna 302 after the transparent antenna 302 is powered on, so that the transparent antenna 302 can be quickly heated, which is beneficial for the automobile glass to be quickly defogged and defrosted after the transparent antenna 302 is applied to the automobile glass.

[0042] After 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 block the penetration of infrared rays, thus affecting the normal operation of the infrared camera. In addition, the metal film layer or transparent conductive oxide film layer in the transparent antenna 302 has the characteristic of reflecting infrared rays, making the automobile glass more obstructive to infrared rays.

[0043] Therefore, in the present application, the reflective layer 104 of the transparent antenna 302 is provided with an infrared anti-reflection film in the area other than the area where the reflective main body is located, that is, the 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 is facing the infrared anti-reflection film. After the automobile 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 surface facing the interior 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.

[0044] In a preferred embodiment of the present application, based on the above embodiment, as Figure 3As shown, 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 from each other and parallel to each other, so that the first layout pattern and the second layout pattern are interlocked with each other and formed in the middle layer 301. In this way, the space of the middle layer 301 can be effectively reused, which is conducive to reducing the thickness of the middle layer 301.

[0045] In a preferred embodiment of the present application, on the basis of the above embodiment, a reflective film is provided in the layer where the antenna vibrator 102 of the above transparent antenna 302 in the above laminated glass is located, and a plurality of through holes are provided in the above transparent antenna 302, and the above through holes are connected from the end surface of the side of the above transparent antenna 302 close to the inside of the vehicle to the above reflective film, so that after the above automotive glass is installed for the side window glass of the vehicle, a one-way perspective reflective film can be formed in the side window glass of the vehicle. That is, after the antenna vibrator 102 is etched, there are also etched areas and unetched areas, and the unetched area of ​​the above antenna vibrator 102 forms the above antenna vibrator 102. The above reflective film is provided in the etched area of ​​the antenna vibrator 102. This is conducive to protecting the privacy of vehicle users and improving the experience of vehicle users.

[0046] In a preferred embodiment of the present application, based on the above 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 the electric heating element 303, which can save the number of components used and simplify the complexity of the process assembly of the automobile glass; and the existence of the electric heating element 303 is reduced. The obstruction to the light transmittance of the automobile front windshield is reduced, which is conducive to enhancing the transparency of the automobile front windshield.

[0047] Another embodiment of the present invention discloses a vehicle. The vehicle is equipped with the automobile glass disclosed in any of the above embodiments. The vehicle includes a channel selection module. The channel selection module is respectively connected to the transparent antenna 302 and the electric heating element 303, and the channel selection module supplies power to the transparent antenna 302 and the electric heating element 303 in a time-sharing manner. Specifically, exemplarily, the channel 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 off of the electric heating element 303. The second control switch is used to control the power on and off of the transparent antenna 302. Among them, when the first control switch is turned on, the second control switch is turned off. Since the electric heating element 303 is heating, it will have a negative impact on the communication signal quality of the transparent antenna 302. Therefore, the present application temporarily turns off the transparent antenna 302 when the electric heating element 303 is heating, so as to avoid causing a bad experience to the user.

[0048] The above-mentioned vehicle also includes a wiper, and the above-mentioned electric heating element 303 is the above-mentioned transparent antenna 302, and the density of the above-mentioned transparent antenna 302 arranged in the wiper projection area of ​​the middle layer 301 of the above-mentioned automobile glass is greater than the density of the above-mentioned transparent antenna 302 arranged in the non-wiper projection area. The above-mentioned wiper projection area is the area corresponding to the positive projection on the automobile glass when the wiper is working. The non-wiper projection area is the area on the automobile glass except the above-mentioned wiper projection area. In this way, it can be avoided that in cold weather, the wiper is frozen on the vehicle windshield due to the low temperature, resulting in the wiper being unable to work normally. In addition, there is no need to set up a special electric heating element 303 for heating, and the transparent antenna 302 can be directly used for heating.

[0049] In a preferred embodiment of the present application, on the basis of the above embodiment, a conductive film layer is provided in the wiper projection area of ​​the intermediate layer 301 of the above automobile glass, and the above conductive film layer is provided between adjacent antenna components 201 of the antenna vibrator 102 in the above transparent antenna 302. In this way, the heating effect of the wiper can be further improved when the wiper is frozen on the vehicle windshield in cold weather without increasing the thickness of the transparent antenna 302 and effectively utilizing the internal space of the transparent antenna 302.

[0050] Another embodiment of the present invention discloses a vehicle control method, which is used to control the vehicle disclosed in any of the above embodiments, wherein the front windshield and the rear windshield of the vehicle are both automobile glasses disclosed in any of the above embodiments. The above method comprises the following steps:

[0051] S10, the vehicle receives the driving parameters of the preceding vehicle from the transparent antenna in the front windshield, adjusts at least part of the driving parameters of the vehicle according to the driving parameters of the preceding vehicle, and transmits the driving parameters of the vehicle to the following vehicle through the transparent antenna in the rear windshield. In this way, the transparent antenna in the car glass can be directly used to realize communication between cars, without the need to use a base station as a signal transmission medium, which is conducive to improving communication efficiency and speed, and is conducive to improving the control accuracy when multiple vehicles are controlled simultaneously.

[0052] Specifically, all the vehicles including the preceding vehicle, the vehicle itself and the following vehicle are unmanned vehicles, and the driving parameters may include the speed, acceleration and expected braking time of the vehicle, etc. The present application is not limited thereto.

[0053] When the step S10 is specifically implemented, it can be achieved by the following steps:

[0054] S101, obtaining the real-time position of the vehicle, and establishing a traffic flow group with the vehicle and a preset number of vehicles traveling in the same direction on the same road.

[0055] S102, combining two vehicles in the above vehicle flow group in sequence to form a plurality of vehicle flow pairs. Each vehicle flow pair includes two adjacent vehicles, the transparent antenna of the first vehicle of the above two vehicles serves as a transmitting end, and the transparent antenna of the second vehicle serves as a receiving end of the first vehicle and also as a transmitting end of the next vehicle. The last vehicle in the above vehicle flow group serves as a receiving end.

[0056] S103: Two adjacent vehicles in the above vehicle flow group establish communication based on transparent antennas.

[0057] And S104, when a third vehicle is inserted between two vehicles of the above-mentioned traffic pair, it is determined whether the above-mentioned third vehicle belongs to the above-mentioned traffic group. If so, the transparent antenna of the above-mentioned third vehicle is used as the receiving end of the previous vehicle in the above-mentioned traffic pair, and the communication between the vehicles located after the above-mentioned third vehicle in the above-mentioned traffic group is adjusted, so that every two adjacent vehicles in the above-mentioned traffic group re-establish communication based on the transparent antenna. Otherwise, no operation is performed, and step S104 is executed repeatedly.

[0058] In this way, after the arrangement order of the traffic group changes, the communication between vehicles based on the transparent antenna can be adjusted in a timely and flexible manner to ensure the communication effect of the traffic group. The above preset number can be set as needed, for example, it can be 5. A traffic group can be a plurality of vehicles traveling in the same direction on the same road with the same destination.

[0059] like Figure 4 As shown, another embodiment of the present invention discloses a vehicle dispatching method, which is used to dispatch the vehicle disclosed in any of the above embodiments. The above vehicle dispatching method includes the following steps:

[0060] S200, using the transparent antenna in the car glass to set up a relay network, and obtaining the location distribution information of all vehicles based on the transparent antenna. That is, the location distribution information of the vehicle can be obtained by using the transparent antenna in the car glass, which solves the problem that the platform cannot obtain the location distribution information of all vehicles in a timely manner because the vehicle driver may be concerned about the mobile network traffic fees generated by mobile phones and other devices and does not open the network in real time, so that it is no longer necessary to rely on the vehicle driver's mobile phone and other devices to obtain the location information.

[0061] S300, obtaining a taxi request submitted by a user device.

[0062] S400, matching a target vehicle for the user corresponding to the user device according to the taxi request and the location distribution information.

[0063] S500: When the target vehicle reaches the current position of the user device, the four turn signals of the target vehicle and the rear flash light of the user device are controlled to flash simultaneously, so that the vehicle driver and the taxi user can quickly find each other, which is conducive to improving the user experience.

[0064] And S600, after the user corresponding to the user device enters the target vehicle and the target vehicle starts to depart, the user device is controlled to access the relay network corresponding to the transparent antenna in the vehicle glass. In this way, after the taxi user enters the target vehicle, he can directly access the Internet through the relay network provided by the transparent antenna in the vehicle, without consuming mobile network traffic, which is conducive to improving the experience of the taxi user.

[0065] It should be noted that all the embodiments disclosed above in this application can be combined arbitrarily, and the technical solutions obtained after the combination are also within the protection scope of this application.
