In addition, when the vehicle antenna is disposed on the outer surface of the windshield of the vehicle, the leads of the antenna need to be bent back through the outer surface to the inner surface to access the circuit. In the related art, a lead of the vehicle-mounted antenna is bent through the edge of the side face of the windshield, the side face of the windshield is often required to be connected with a frame of a vehicle, and part of the lead is located between the side face of the windshield and the frame, so that a gap is formed between the side face of the windshield and the frame, the lead cannot be attached to the side face of the windshield, and water vapor and the like easily enter the gap to affect the performances of the vehicle-mounted antenna and the vehicle. The application provides an antenna glass and vehicle have better connection reliability, and antenna glass can reduce the gap with the better laminating of the car frame of vehicle, guarantees the performance of antenna glass and vehicle.

As shown in fig. 1, the vehicle 100 includes an antenna glass 10 and a vehicle frame 20. The vehicle 100 may be a car, a bus, a truck, a work-type special vehicle, a transportation-type special vehicle, or the like. The antenna glass 10 may be a front windshield, a rear windshield, a side window glass, a door window glass, or the like of the vehicle 100. The frame 20 corresponds to the antenna glass 10, and may be a head frame, a tail frame, a roof frame, a door, or the like. In the embodiment of the present application, the antenna glass 10 corresponds to a front windshield of the vehicle 100, and the vehicle frame 20 corresponds to a vehicle head frame. It is understood that the description of the antenna glass 10 and the vehicle frame 20 in the embodiment of the present application also applies to other glasses in the vehicle 100 and the vehicle frame 20 corresponding thereto. The antenna glass 10 is connected to the vehicle frame 20. The antenna glass 10 and the vehicle frame 20 may be fixedly connected by an adhesive. When the antenna glass 10 is connected with the vehicle frame 20, the antenna glass 10 can be well bonded with the vehicle frame 20 by ensuring that the outer peripheral surface of the antenna glass 10 is flat and has no parts protruding from the outer peripheral surface of the antenna glass 10.

For convenience of description, the length direction of the antenna glass 10 is defined as an X-axis direction, the width direction of the antenna glass 10 is defined as a Y-axis direction, and the thickness direction of the antenna glass 10 is defined as a Z-axis direction.

Referring to fig. 1 and 2, in an embodiment, the frame 20 is a rectangular frame, and includes a top frame, a first side frame 201, a bottom frame, and a second side frame 202 connected in sequence, where the top frame and the bottom frame are disposed oppositely along a Y-axis direction, and the first side frame 201 and the second side frame 202 are disposed oppositely along an X-axis direction, where the Y-axis is perpendicular to an XZ plane. The bottom frame is close to the ground compared with the top frame. Two surfaces of the antenna glass 10 facing each other in the X-axis direction need to be connected to the first side frame 201 and the second side frame 202, respectively. Two opposite surfaces of the antenna glass 10 in the Y-axis direction need to be connected to the top frame and the bottom frame, respectively.

Referring to fig. 1 and 2, the antenna glass 10 includes a first glass plate 101, a second glass plate 102, and an antenna element 103. The first glass plate 101 and the second glass plate 102 are both made of transparent materials. The first glass plate 101 and the second glass plate 102 are stacked in the thickness direction (i.e., the Z-axis direction) of the antenna glass 10. The first glass plate 101 includes a first surface 110 and a third surface 112 opposite to each other, and a second side surface 114 sandwiched between the first surface 110 and the third surface 112. The first surface 110 and the third surface 112 are two surfaces of the first glass plate 101 facing the Z-axis direction. The first surface 110 and the third surface 112 may be planar or arc-shaped. The second side surface 114 may be one of two surfaces of the first glass plate 101 in the length direction (i.e., the X-axis direction), or may be one of two surfaces of the first glass plate 101 in the width direction (i.e., the Y-axis direction). The second glass piece 102 includes a second surface 120, a fourth surface 122, and a first side 124. The second surface 120 is opposite to the fourth surface 122, the first side surface 124 is sandwiched between the second surface 120 and the fourth surface 122, and the second surface 120 and the fourth surface 122 are two surfaces of the first glass plate 101 facing the Z-axis direction. The second surface 120 and the fourth surface 122 may be planar or arcuate. The first side surface 124 may be one of two surfaces of the second glass plate 102 in the length direction (i.e., the X-axis direction), or may be one of two surfaces of the second glass plate 102 in the width direction (i.e., the Y-axis direction).

The first surface 110 of the first glass plate 101 is bonded to the second surface 120 of the second glass plate 102 such that the first glass plate 101 is integrally connected to the second glass plate 102. In one embodiment, the first surface 110 is bonded to the second surface 120 through an intermediate layer, which may be an encapsulant or the like. Optionally, the first surface 110 and the second surface 120 are both flat surfaces or arc surfaces with the same radian, so that the first surface 110 and the second surface 120 can be completely attached when being joined, and no more gaps are generated.

The following embodiment will be described by taking as an example that the first side surface 124 is one of two surfaces of the second glass plate 102 along the X-axis direction, the second side surface 114 is a surface of the first glass plate 101 along the X-axis direction corresponding to the first side surface 124, the third surface 112 faces the outside of the vehicle 100 and is an outer surface of a windshield of the vehicle 100, and the fourth surface 122 faces the inside of the vehicle 100 and is an inner surface of the windshield of the vehicle 100. It is understood that the features described in the embodiments of the present application are equally applicable to the manner in which the third surface 112 of the first glass sheet 101 is the inner surface of the windshield of the vehicle 100, and the fourth surface 122 of the second glass sheet 102 is the outer surface of the windshield of the vehicle 100, and the first side 124 and the second side 114 are along the Y-axis direction.

Referring to fig. 2 and 3, one end of the first surface 110 extends out relative to the second surface 120. Specifically, one end of the first surface 110 in the X-axis direction extends relative to one end of the second surface 120 close to the first side surface 124, and the other end of the first surface 110 in the X-axis direction is flush with, retracted into, or extended from one end of the second surface 120 away from the first side surface 124. In one embodiment, the length of the second glass plate 102 along the X-axis direction is less than the length of the first glass plate 101 along the X-axis direction, the first side surface 124 and the second side surface 114 are staggered along the X-axis direction, and the other side surface of the first glass plate 101 along the X-axis direction is flush with the other side surface of the second glass plate 102 along the X-axis direction.

In another embodiment, referring to fig. 2 and 4, the length of the second glass plate 102 along the X-axis direction may be greater than or equal to the length of the first glass plate 101 along the X-axis direction. When the length of the second glass plate 102 is greater than or equal to the length of the first glass plate 101, the first glass plate 101 and the second glass plate 102 are arranged in a staggered manner, one end of the first surface 110 extends out relative to the second surface 120, and the other end of the first surface 110 retracts relative to the second surface 120.

As shown in fig. 2, a hollow portion 104 is disposed between one end of the first surface 110 and the first side surface 124. It can be understood that when the first surface 110 is attached to the second surface 120, the first side surface 124 and the protruding portion of the first surface 110 enclose the hollow portion 104. When the first surface 110 and the second surface 120 are bonded through the intermediate layer, the first side surface 124, the intermediate layer, and the protruding portion of the first surface 110 enclose the hollow portion 104.

As shown in fig. 2, the antenna element 103 is used for transceiving antenna signals. The antenna element 103 includes a radiating portion 131 and a lead portion 132. The radiation unit 131 receives the guided wave transmitted through the lead unit 132 and converts the guided wave into an electromagnetic wave radiated toward the first glass plate 101. The lead portion 132 is used to receive an antenna signal. The radiation portion 131 is integrally formed with the lead portion 132. The thicknesses of the radiation portion 131 and the lead portion 132 in the Z-axis direction may be as small as a nanometer scale. The radiation portion 131 and the lead portion 132 are integrally formed, so that loss of an antenna signal during transmission can be reduced, and processing of the antenna element 103 can be facilitated. In addition, when the processed antenna element 103 is integrated with the first glass plate 101 and the second glass plate 102 through the intermediate layer, the integrated antenna element 103 can ensure the reliability of the electrical connection between the radiation part 131 and the lead part 132, reduce the difficulty of the laminating process of the first glass plate 101 and the second glass plate 102, and reduce the process steps. In one embodiment, the radiation portion 131 and the lead portion 132 are formed on a flexible film. The radiation portion 131 and the lead portion 132 may be formed on the flexible film by printing, coating, etching, or the like. The radiation portion 131 and the lead portion 132 may be directly electrically connected or coupled electrically connected. When the radiation portion 131 and the lead portion 132 are coupled and electrically connected, the loss of the antenna signal transferred between the radiation portion 131 and the lead portion 132 can be reduced. The radiation part 131 is disposed between the first glass plate 101 and the second glass plate 102, and is fixed between the first glass plate 101 and the second glass plate 102 after the first surface 110 and the second surface 120 are bonded. One end of the lead portion 132 is located between the first surface 110 and the second surface 120 and connected to the radiation portion 131, and the other end of the lead portion 132 is located in the hollow portion 104. Specifically, the other end of the lead portion 132 does not extend outside the first surface 110 in the X-axis direction. When the first glass plate 101 is fixedly connected to the first side frame 201, the lead portion 132 is located between the second side surface 114 and the first side surface 124 along the X-axis direction, so that the gap between the first side frame 201 and the antenna glass 10 can be prevented from increasing when the lead portion 132 is located between the first side frame 201 and the second side surface 114 along the X-axis direction. Meanwhile, the other end of the lead portion 132 is disposed in the hollow portion 104, so that the lead portion 132 can be prevented from being damaged when the first side frame 201 is pressed against the antenna glass 10. As can be understood, the orthographic projection of the lead portion 132 falls entirely within the first surface 110, and the lead portion 132 can be ensured to have less influence on the connection of the antenna glass 10 and the first side frame 201.

By providing the antenna glass 10, the first glass plate 101 is bonded to the second glass plate 102, the hollow part 104 is provided between the first surface 110 of the first glass plate 101 and the first side surface 124 of the second glass plate 102, and the lead wire 132 of the antenna is led out into the hollow part 104 through the space between the first surface 110 and the second surface 120, in other words, the orthographic projection of the other end of the lead wire 132 is located on the first surface 110, so that when the first glass plate 101 is connected to the external first side frame 201, the first glass plate 101 can be attached to the first side frame 201 without being affected by the lead wire 132. In addition, the first glass plate 101 partially extends out of the second glass plate 102 to form the hollow-out portion 104, so that compared with a mode of forming a hole in the glass and penetrating through a lead, the integrity of the glass can be guaranteed, and cracks and the like caused by the hole are reduced.

As shown in fig. 5, the radiation portion 131 is disposed to be attached to the first surface 110. The lead part 132 includes a first lead part 132a and a second lead part 132 b. Opposite ends of the first lead portion 132a are connected to the radiation portion 131 and the second lead portion 132b, respectively. The first lead portion 132a is located between the first surface 110 and the second surface 120 and is disposed to be attached to the first surface 110. The radiation portion 131 is integrally formed with the first lead portion 132 a. The second lead portion 132b is located in the hollow portion 104, and the second lead portion 132b is used for connecting an external circuit. Optionally, the second lead portion 132b is integrally formed with the first lead portion 132a to reduce loss of the antenna signal during transmission on the lead portion 132. It is understood that the length of the first lead part 132a is determined according to the installation position of the radiation part 131. The second lead portion 132b is connected to an external circuit in the hollow portion 104, so that the total length of the lead portion 132 can be reduced, the loss of the antenna signal can be reduced, and the transceiving performance of the radiation portion 131 can be improved.

Alternatively, as shown in fig. 5, one end of the second lead portion 132b is connected to the side of the first lead portion 132a away from the first surface 110, and the other end of the second lead portion 132b away from the first lead portion 132a is attached to the first side surface 124. The other end of the second lead portion 132b is provided with a power feeding portion 133, and the power feeding portion 133 is used for electrical connection with an external power feeding source. Alternatively, the feeding unit 133 is connected to the feeding source through a coaxial cable, may be coupled to the feeding source, or may be electrically connected to the feeding source through a Flexible Printed Circuit (FPC). The feeding portion 133 is disposed on the second lead portion 132b, so that the second lead portion 132b can be directly electrically connected to the feeding source without extending the second lead portion 132b to the side of the second glass plate 102 away from the first glass plate 101, and the influence on the performance of the antenna element 103, such as reliability, can be avoided or reduced by reducing the bending path of the second lead portion 132 b.

In one embodiment, the feeding portion 133 is disposed on a side of the second lead portion 132b facing the first side surface 124, and the feeding portion 133 is connected to the feeding source through the second lead portion 132b and the first side surface 124. In this embodiment, the feeding portion 133 is far away from the first side frame 201, so that the feeding portion 133 can be prevented from being conducted with metal in the first side frame 201, which may cause an accident. In another embodiment, the feeding portion 133 is disposed on a side of the second lead portion 132b away from the first side surface 124, and the feeding portion 133 is connected to the feeding source through a hollow portion. In this embodiment, the feeding portion 133 is connected to the feeding source through the hollow portion, and the hollow portion can be used to hide and accommodate the connection line electrically connected between the feeding portion 133 and the feeding source, so that the second glass plate 102 maintains high transparency through reasonable wiring. It is understood that, in the embodiment of the present invention, the radiation portion 131 and the lead portion 132 can be made of transparent conductive materials, such as: indium Tin Oxide (ITO) and the like, which are transparent conductive materials, realize ETC communication, realize intelligent charging, and do not affect the visibility of the first glass plate 101 and the second glass plate 102.

Thus, when the first glass plate 101 and the second glass plate 102 are flush at one end in the X-axis direction, the hollow portion 104 is formed between the first side surface 124 of the second glass plate 102 and the first glass plate 101. Of course, in other embodiments, the second glass plate 102 may also be a trapezoidal plate or the like. In this embodiment, the second glass plate 102 has a simple structure and is easy to process.

In another embodiment, referring to fig. 2 and 6, the first glass plate 101 is a rectangular plate, and the first side surface 124 of the second glass plate 102 includes a first sub-side surface 124a and a second sub-side surface 124b intersecting with each other. An orthographic projection of the intersection of the first sub-flank 124a and the second sub-flank 124b lies within the first surface 110. An orthographic projection of an end of the first sub-side 124a away from the second sub-side 124b is located on a side line of the first surface 110. The orthographic projection of the end of the second sub-side 124b remote from the first sub-side 124a is also located on the side line of the first surface 110. In fig. 6(a), the first sub-side 124a is parallel to the second side 114 of the first glass plate 101, and the second sub-side 124b is inclined with respect to the first sub-side 124 a. Alternatively, as shown in fig. 6(b), the first sub-side 124a and the second sub-side 124b are both inclined with respect to the second side 114 of the first glass plate 101, and a hollow portion 104 with a triangular cross section is formed between the first glass plate 101 and the second glass plate 102. In this embodiment, the area of the second surface 120 of the second glass plate 102 is large, and the area of the joint between the second glass plate 102 and the first glass plate 101 is increased, so that the reliability of the joint between the first glass plate 101 and the second glass plate 102 can be improved.

In another embodiment, referring to fig. 2 and 7, the first glass plate 101 is a rectangular plate, the first side surface 124 includes a third sub-side surface 124c, a fourth sub-side surface 124d and a fifth sub-side surface 124e which are sequentially connected, the third sub-side surface 124c and the fifth sub-side surface 124e are flush with a border line of the first surface 110, and an orthogonal projection of the fourth sub-side surface 124d is located in the first surface 110. The fourth sub-side 124d is recessed in the X-axis direction with respect to the third and fifth sub-sides 124c and 124 e. In one embodiment, the fourth sub-side 124d is an arc-shaped surface. Of course, in other embodiments, the fourth sub-side surface 124d may be formed by a plurality of rectangular surfaces. In this embodiment, the third sub-side surface 124c and the fifth sub-side surface 124e are flush with the second side surface 114 of the first glass plate 101, and the third sub-side surface 124c and the fifth sub-side surface 124e can be used for connecting the first side frame 201, so that the connection area between the antenna glass 10 and the first side frame 201 is increased, and the connection reliability between the antenna glass 10 and the first side frame 201 is improved.

Further, as shown in fig. 8, the antenna glass 10 further includes a circuit board 30, and the circuit board 30 is used for connecting with the lead portion 132 to supply a high-frequency electric signal to the antenna element 103.

Alternatively, the circuit board 30 is located between the second lead portion 132b and the first side frame 201 in the X-axis direction. In other words, a certain gap is maintained between the feeding unit 133 and the first side frame 201, and in this case, the first side frame 201 and the feeding unit 133 can be prevented from being coupled to affect the signal of the antenna element 103. In other embodiments, the circuit board 30 may be fixed in the hollow portion 104 by directly bonding the first glass plate 101, the second glass plate 102, the first side frame 201, and the like, or the circuit board 30 may be fixed in the hollow portion 104 by directly bonding the bracket and the like, or by fastening the bracket, the first side frame 201, and the like.
