Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

In the description of the embodiments of the present application, it should be understood that the terms "thickness" and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, and do not imply or indicate that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.

Referring to fig. 1 and 2, the present application provides a vehicle glazing 100, where the vehicle glazing 100 includes a laminated glass 10 and an antenna assembly 20, and the antenna assembly 20 is embedded in the laminated glass 10. The antenna assembly 20 comprises an oscillator 21, a matching loop 22 and a radio frequency chip 23, wherein the oscillator 21 is coupled with the matching loop 22, and the radio frequency chip 23 is electrically connected with the matching loop 22. It is understood that the window glass 100 may be applied to a vehicle device such as an automobile, a truck, a bus, etc., and the window glass 100 may be a front windshield.

The antenna assembly 20 comprises a vibrator 21, a matching loop 22 and a radio frequency chip 23, the matching loop 22 is used for being coupled with the vibrator 21, and the radio frequency chip 23 feeds power to the vibrator 21 through the matching loop 22, so that the coupling capability of the antenna assembly 20 is enhanced, the signal transmitting and receiving capability is enhanced, the communication distance is enhanced, and the normal working requirement is met.

In the present embodiment, the laminated glass 10 may be formed by laminating a plurality of glass sheets. The laminated glass 10 has a first surface 101 and a second surface 102 disposed opposite the first surface 101. After the window glass 100 is mounted in an automobile, the first surface 101 of the laminated glass 10 is disposed to face outward, and the second surface 102 is disposed to face inward. The first surface 101 may be a curved surface protruding outward, and the second surface 102 is disposed substantially parallel to the first surface 101. The distance from the element 21 and the matching loop 22 to the first surface 101 is smaller than the distance from the element 21 and the matching loop 22 to the second surface 102, so that the antenna signal receiving and transmitting capacity of the element 21 and the matching loop 22 is increased, and the communication performance of the antenna assembly 20 is enhanced.

The oscillator 21 is close to the edge of the laminated glass 10 relative to the matching ring 22, so that the radio frequency chip 23 is arranged far away from the edge of the laminated glass 10. When the vehicle window glass 100 is applied to a vehicle, the edge of the laminated glass 10 is close to the frame of the vehicle, that is, the electromagnetic interference of the edge of the laminated glass 10 is large, and the radio frequency chip 23 is arranged far away from the edge of the laminated glass 10 to reduce the electromagnetic interference.

the laminated glass 100 comprises a first long side 103, a second long side 14 arranged opposite to the first long side 103 and two opposite short sides 105. The two short sides 105 are connected between the first long side 103 and the second long side 104. The matching ring 22 is disposed away from the first long side 103 with respect to the vibrator 21. The vibrator 21 is disposed adjacent to the first long side 103. The distance from the oscillator 21 to the first long side 103 can be adjusted as required, so as to reduce the influence of the antenna component 20 on the visible range of the laminated glass 20 and ensure the communication requirement of the antenna component 20.

In this embodiment, the vibrator 21 and the matching ring 22 are made of gold, copper, silver, or conductive silver paste. The radiator 21 may be formed by using a plurality of different metal layers. The vibrator 21 and the matching ring 22 may be printed and molded in the laminated glass 10 by a silk-screen printing technique. The rf chip 23 may be a passive rf chip. A feeding circuit may be disposed in the rf chip 23, so as to transmit and receive antenna signals through the oscillator 21 and the matching loop 22 by using the feeding circuit. The rf chip 23 may be soldered to the matching ring 22, or may be conductively bonded to the matching ring 22 through a conductive silver paste. Of course, in other embodiments, the rf chip 23 may be electrically connected to the matching ring 22 by a conductive adhesive bonding process under a hot pressing condition.

In another embodiment, as shown in fig. 3, the rf chip 23 may also be an active rf chip. The vehicle window glass 100 further comprises a chip conducting wire 230 embedded in the laminated glass 10 and a conducting elastic sheet 2300 electrically connected with the chip conducting wire 230. One end of the chip conducting wire 230 is connected to the radio frequency chip 23, and the other end extends to the edge of the laminated glass 10 and is connected to the conductive elastic piece 2300. The conductive elastic sheet 2300 is fixed to the edge of the laminated glass 10 and is located on the side wall of the laminated glass 10. When the window glass 100 is applied to a vehicle, the conductive elastic sheet 2300 may be connected to a power feeding source and a processor of the vehicle via a conductive cable, so that the rf chip 23 receives a power feeding signal and transmits the power feeding signal to the processor of the vehicle.

it can be understood that the radio frequency identification base station can send a radio frequency signal with a certain frequency through the antenna by the reader-writer, when the antenna assembly 20 enters a radio frequency signal area sent by the radio frequency identification base station, the radio frequency chip 23 can receive the radio frequency signal through the oscillator 21 and the matching ring 22, process the radio frequency signal, send a self-encoding response radio frequency signal through the matching ring 22 and the oscillator 21, the encoding response radio frequency signal is obtained by the reader-writer of the radio frequency identification base station, and is decoded and sent to the data exchange and management system for processing, so as to realize automatic identity identification.

Further, with continuing reference to fig. 1 and fig. 2, the communication distance of the radio frequency chip 23 through the resonant signal formed by the matching loop 22 and the vibrator 21 is greater than 20 meters.

In this embodiment, the radio frequency of the antenna assembly 20 is 900mHz to 950 mHz. Preferably, the rf frequency of the antenna assembly 20 may be 922mHz to 925mHz, so as to ensure that the antenna assembly 20 has a sufficient communication distance and meets the normal communication requirement. When the rf frequency of the antenna assembly 20 is less than 922mHz, the communication distance of the antenna assembly 20 is reduced, and when the frequency of the antenna assembly 20 is greater than 925mHz, the signal strength of the antenna assembly 20 is reduced. The antenna assembly 20 is operable to receive radio frequency signals from a radio frequency identification base station over a distance of at least 20 meters,The antennathe range over which the self-encoding reply radio frequency signal can be efficiently transmitted to the radio frequency identification base station is also at least 20 meters. After the window glass 100 is installed in an automobile, the radio frequency chip 23 can receive a radio frequency signal of a radio frequency identification base station and send a self-coded response radio frequency signal according to the radio frequency signal within a range of approximately 20 meters from the radio frequency identification base station when the automobile runs, so as to realize automatic identification. The oscillator 21 is coupled to the matching loop 22, and the matching loop 22 effectively matches the capacitive reactance and the inductive reactance of the antenna, so that the signal coupling capability of the oscillator 21 is enhanced, and the radio frequency signal receiving and transmitting capability of the antenna assembly 20 is enhanced, so that the radio frequency signal can be still received under the condition that the distance between the oscillator 21 and the radio frequency identification base station is 20 meters, and the response radio frequency signal can be effectively transmitted to the radio frequency identification base station.

It is understood that the distance from the oscillator 21 to the matching loop 22 determines the rf gain of the antenna assembly 20, so as to satisfy the structural optimization of the antenna assembly 20, increase the communication distance, and satisfy the normal communication requirements. The distance between the two ends of the oscillator 21 and the matching ring 22 determines the real part and the imaginary part of the antenna assembly 20, so as to satisfy the radio frequency bandwidth requirement of the antenna assembly 20, increase the communication distance, and satisfy the normal communication requirement. The antenna assembly 20 can meet the vehicle identity identification function, can also meet the vehicle ETC function, and meets the multifunctional requirement.

Further, referring to fig. 4, the rf chip 23 is connected to the matching ring 22 away from the vibrator 21.

The matching loop 22 is provided with a feeding point at a position far from the vibrator 21. The rf chip 23 is connected to the feeding point. The feeding point of the matching loop 22 is far away from the oscillator 21, so that the length of the matching loop 22 can be adjusted conveniently, the coupling requirement of the matching and the oscillator 21 is ensured, the impedance of the matching loop 22 is adjusted, the impedance of the oscillator 21 and the matching loop 22 can be adjusted to be matched with the impedance of the radio frequency chip 23 in a conjugate mode, namely, the load impedance of the antenna component 20 is adjusted to be conjugated with the signal source impedance, and the signal output power maximization requirement is met.

In one embodiment, the rf chip 23 includes a first edge 231 and a second edge 232 disposed opposite to the first edge 231, and the matching ring 22 includes a first radiating arm 221 extending from the first edge 231 and a second radiating arm 222 extending from the second edge 232. The length of the first radiating arm 221 and the length of the second radiating arm 222 can be adjusted according to actual needs, so as to adjust the impedance of the matching loop 22. The first radiating arm 221 and the second radiating arm 222 may be disposed flush in the same linear direction. The width of the first radiating arm 221 is equal to the width of the second radiating arm 222, so as to ensure the impedance balanced arrangement of the matching loop 22, and further ensure the signal transceiving capacity of the oscillator 21.
