DETAILED DESCRIPTION

[0034] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and claimed herein. It is therefore intended that the present application not be limited in scope to the specific embodiments disclosed but rather that the scope of the present application be measured by the broadest permissible interpretation of the claims.

[0035] Reference Figure 1 The present application provides a vehicle, which comprises an antenna glass assembly 100 and an external power supply. The antenna glass assembly 100 and the external power supply can be mounted on the vehicle body, such as the top of the vehicle body (sunroof position), or the front and rear windows of the vehicle body. The antenna glass assembly 100 is electrically connected to the external power supply 200, and can receive or send electromagnetic signals through the antenna glass assembly 100 to connect with the internal controller or external controller, so as to expand the performance of the vehicle. The external power supply 200 can be the vehicle's own power supply (such as a vehicle battery), or an external power supply (such as an independent battery, etc.).

[0036] The antenna glass assembly 100 provided by an embodiment of the present application comprises a glass substrate assembly 110, an antenna assembly 120 and a feeding assembly 130.

[0037] Specifically, the glass substrate assembly 110, the antenna assembly 120 and the feeding assembly 130 are combined Figure 2 , Figure 3 and Figure 4As shown, the antenna assembly 120 is arranged on the glass substrate assembly 110. The feeding assembly 130 includes a conductive piece 131 and a contact piece 132. The conductive piece 131 is arranged on the glass substrate assembly 110, and the antenna assembly 120 is electrically connected with the conductive piece 131. The contact piece 132 is used to feed the antenna assembly 120. The side of the conductive piece 131 away from the glass substrate assembly 110 is connected with the contact piece 132, so that the conductive piece 131 and the contact piece 132 are electrically connected, so that the antenna assembly 120 is electrically connected with the contact piece 132 and the external power supply.

[0038] In the embodiment, the electrical connection between the conductive piece 131 and the antenna assembly 120 refers to a contact type electrical connection or a non-contact type electrical connection (such as a coupling connection) between the conductive piece 131 and the antenna assembly 120. The contact type electrical connection can be, but is not limited to, a wired connection, a welding connection, or an adhesive connection. It can be understood that generally, if the antenna assembly 120 arranged on the glass substrate assembly 110 is directly electrically connected with the contact piece 132 by welding or other non-detachable methods, the structure of the electrical connection site is relatively weak and is prone to corrosion. With the increase of use time, the contact piece 132 is easily damaged, thereby resulting in the need to replace the entire glass substrate assembly 110, which has a high replacement cost. At the same time, a large number of direct connection sites between the antenna assembly 120 and the glass substrate assembly 110 affect the structural hardness of the glass substrate assembly 110, which is not conducive to the structural hardness of the glass substrate assembly 110.

[0039] In the embodiment, the conductive piece 131, which is not easily damaged, is used as a transition piece between the antenna assembly 120 and the contact piece 132, so that the antenna assembly 120 and the contact piece 132 do not need to be directly electrically connected, and there is no non-detachable direct electrical connection site between the antenna assembly 120 and the contact piece 132. Therefore, in the electrical connection process between the external power supply 200 and the antenna assembly 120, if the contact piece 132 is damaged, only the contact piece 132 on the conductive piece 131 or the device connected with the contact piece 132 on the conductive piece 131 needs to be replaced, thereby avoiding the replacement of the glass substrate assembly 110, saving the replacement cost and improving the replacement efficiency. At the same time, the damage (such as scratching) of the glass substrate assembly 110 caused by the direct welding of the contact piece 132 and the antenna assembly 120 is avoided, the processing difficulty is reduced, and the processing efficiency is improved.

[0040] Further, in some embodiments, the antenna assembly 120 includes a first antenna unit 121 and a second antenna unit 122. The first antenna unit 121 is provided with a first feeding portion 121a for feeding cooperation with the external power source 200. The second antenna unit 122 is provided with a second feeding portion 122a for feeding cooperation with the external power source 200. The conductive member 131 is configured to be electrically connected with the external power source 200. The external power source 200 is electrically connected with the conductive member 131 through the power connection member 132, so that the conductive member 131 can be electrically connected with at least one of the first feeding portion 121a and the second feeding portion 122a.

[0041] In this way, the first antenna unit 121 and the second antenna unit 122 in the antenna assembly 120 can emit electromagnetic wave signals of different frequency bands or the same channel, which can improve the antenna performance of the antenna glass assembly 100, such as the radiation range, the radiation intensity, and the bandwidth of the electromagnetic wave.

[0042] In addition, the conductive member 131 and the antenna assembly 120 can be connected in various ways. Alternatively, the conductive member 131 and the antenna assembly 120 can be connected in a detachable manner. In a specific embodiment, the detachable connection can be an adhesive connection (when the conductive member 131 and the antenna assembly 120 are connected by adhesive, they can be detached by heating, etc.). Specifically, the feeding assembly 130 includes an adhesive layer that is bonded between the conductive member and the glass substrate assembly, and the adhesive layer is an insulating adhesive or a conductive adhesive. The insulating adhesive can be a rubber tape, and the conductive adhesive can be a 3M conductive adhesive. In one example, the first feeding portion 121a is electrically connected with the conductive member 131 through the adhesive layer. In another example, the second feeding portion 122a is electrically connected with the conductive member 131 through the adhesive layer.

[0043] In this way, unlike the conductive member 131 being electrically connected with the antenna assembly 120 through a wire, the conductive member 131 and the antenna assembly 120 are electrically connected through the adhesive layer, which is conducive to improving the connection and integration performance of the conductive member 131 and the antenna assembly 120, and is conducive to the miniaturization of the antenna glass assembly 100. Further, the adhesive layer has a certain flexibility and buffering performance, so that when the external power source 200 is connected with the conductive member 131, the adhesive layer can reduce the impact force of the conductive member 131 on the antenna assembly 120, thereby providing better protection for the antenna assembly 120 and the glass substrate assembly 110.

[0044] Correspondingly, it should be noted that the connection between the conductive member 131 and the power connection member 132 can be a detachable connection such as plug-in or abutment, or a non-detachable connection.

[0045] In some other embodiments, the electrically conductive member 131 and the electrically connecting member 132 are connected in a non-detachable manner. In one embodiment, the electrically conductive member 131 and the electrically connecting member 132 are welded. In this way, the electrically conductive member 131 and the electrically connecting member 132 are electrically connected and integrated, and the welding connection can provide a strong connection between the electrically conductive member 131 and the electrically connecting member 132, thereby improving the stability of the connection.

[0046] In another embodiment, the power feeding assembly 130 further comprises a connecting layer for connecting the electrically conductive member 131 and the electrically connecting member 132, and the connecting layer is conductive glue. In this way, the connecting layer can serve as a transition piece for the electrically conductive member 131 and the electrically connecting member 132, which is convenient to set and improves the processing efficiency. On the one hand, the conductive glue is easy to set, which improves the processing efficiency of the connection process of the electrically conductive member 131 and the electrically connecting member 132. On the other hand, the conductive glue has a certain thickness, which can provide a certain buffer space for the electrically conductive member 131 and the electrically connecting member 132, effectively absorbing the impact force of the electrically connecting member 132 on the electrically conductive member 131, and better protecting the antenna assembly 120 and the glass substrate assembly 110.

[0047] In order to improve the working stability of the electrically conductive member 131, in combination with Figure 3 and Figure 4 As shown in FIG. 1, in combination with any of the above embodiments of the electrically conductive member 131, the electrically conductive member 131 is provided with an electrically connecting end 131a and a grounding end 131b. The electrically connecting end 131a and the grounding end 131b are electrically connected. One of the electrically connecting end 131a and the grounding end 131b is electrically connected with the first feeding portion 121a, and the other is electrically connected with the second feeding portion 122a. When the feeding circuit is in a closed state, the first feeding portion 121a and the second feeding portion 122a can be simultaneously fed by the electrically connecting end 131a and the grounding end 131b. For example, the electrically connecting end 131a is electrically connected with the first feeding portion 121a, and the grounding end 131b is electrically connected with the second feeding portion 122a. That is, in one example, the electrically connecting member 132 is provided with an electrically conductive portion 132a and a grounding portion 132b. The input end of the external power source 200, the electrically conductive portion 132a, the electrically connecting end 131a, the grounding end 131b, the grounding portion 132b, and the output end of the external power source 200 are connected in sequence to form a feeding circuit.

[0048] Thus, unlike directly using the glass substrate assembly 110 as the low phase, which would result in poor antenna stability, the conductive component 131 has a power connection terminal 131a and a ground terminal 131b, which allows the antenna glass assembly 100 to be grounded. This enables the antenna assembly 120 to form a larger phase difference, thereby making the antenna glass assembly 100 more stable and providing better radiation performance. Furthermore, the radiation of the first antenna element 121 and the second antenna element 122 can be controlled simultaneously by the feeding circuit, enriching the antenna performance of the antenna glass assembly 100.

[0049] In one specific implementation, see back Figure 1 The connecting element 132 can be a coaxial cable. Specifically, the coaxial cable includes a wire and a shielding shell wound around the wire. A conductive part 132a is disposed on the wire, and a grounding part 132b is disposed on the shielding shell. The conductive part 132a can be electrically connected to the connecting terminal 131a, and / or the grounding part 132b can be electrically connected to the grounding terminal 131b, so that the conductive part 132a can be powered by the first power supply part 121a, and the grounding part 132b can be powered by the second power supply part 122a. In this way, the coaxial cable has a relatively simple structure, is readily available, and is easy to manufacture.

[0050] It should be noted that the glass substrate assembly 110 can be a single layer of glass or a multi-layer glass stack, etc. The number of multi-layer glass can be, but is not limited to, 2 layers, 3 layers, 4 layers, etc., without too many restrictions.

[0051] In conjunction with any embodiment of the glass substrate assembly 110 described above, see back Figure 5 The glass substrate assembly 110 includes a first glass element 111 and a second glass element 112. The first glass element 111 and the second glass element 112 are arranged along the thickness direction of the glass substrate assembly 110. The first glass element 111 has a first surface 111a and a second surface 111b facing away from each other along the thickness direction. The second glass element 112 has a third surface 112a and a fourth surface 112b facing away from each other along the thickness direction. The second surface 111b and the third surface 112a are arranged facing each other. A conductive element 131 is disposed on the first surface 111a or the fourth surface 112b.

[0052] In one embodiment, the vehicle has a driver's cabin, and the fourth surface 112b is disposed close to the driver's cabin relative to the first surface 111a. The antenna assembly 120 and the conductive element 131 are disposed on the fourth surface 112b.

[0053] In another embodiment, the conductive element 131 is spaced apart from the antenna assembly 120, and at least a portion of the orthographic projection area of ​​the antenna assembly 120 on the glass substrate assembly 110 overlaps with at least a portion of the orthographic projection area of ​​the conductive element 131 on the glass substrate assembly 110, thereby coupling the antenna assembly 120 and the conductive element 131. This spaced-apart arrangement of the conductive element 131 and the antenna assembly 120 helps reduce interference to the conductive element 131 when the connecting element 132 is connected to it, thus better protecting the antenna assembly 120 and the glass substrate assembly. Furthermore, the coupling connection between the antenna assembly 120 and the conductive element 131 helps reduce the number of wiring components, thereby improving the integration performance of the antenna glass assembly 100.

[0054] Specifically, it should be noted that the conductive component 131 in the above embodiments can be a metal plate such as a copper plate, or a composite material such as a circuit board 1311.

[0055] In some embodiments, see back Figure 4 The conductive component 131 includes a circuit board 1311. The first feed section 121a is short-circuited to the second feed section 122a through the circuit board 1311. The power connection terminal 131a and the grounding terminal 131b are disposed on the circuit board 1311, and the power connection terminal 131a is electrically connected to the grounding terminal 131b through the circuit board 1311. It is understood that the fact that both the power connection terminal 131a and the grounding terminal 131b are disposed on the circuit board 1311 is beneficial to improving the integration performance of the conductive component 131 and ensuring that the conductive component 131 and the antenna assembly 120 can maintain a flat fit. This is beneficial to reducing the volume occupied by the antenna glass assembly 100 in the thickness direction, thereby contributing to the miniaturization of the antenna glass assembly 100. Furthermore, the plate-shaped design of the circuit board 1311 results in a smaller footprint in the thickness direction, thus not significantly affecting the overall thickness of the antenna glass assembly 100, which helps to ensure the thin and light performance of the antenna glass assembly 100.

[0056] It should be noted that the circuit board 1311 in the above embodiments can be a single-sided board or a double-sided board (i.e., both sides that are arranged opposite to each other can be used for conduction).

[0057] In one implementation, see back Figure 4 The circuit board 1311 is provided with a first conductive hole 1311a and a second conductive hole 1311b. One end of the first conductive hole 1311a can be electrically connected to the power receiving terminal 131a, and the other end can be electrically connected to the first power supply part 121a, so that the power receiving terminal 131a can be electrically connected to the first power supply part 121a through the first conductive hole 1311a. It should be noted that the first conductive hole 1311a can be directly provided in the power receiving terminal 131a and / or the first power supply part 121a, or it can be not directly provided.

[0058] One end of the second conductive hole 1311b is grounded with the ground end 131b, and the other end is fed with the second feeding part 122a, so that the power connection end 131a is fed with the second feeding part 122a through the second conductive hole 1311b. Correspondingly, the second conductive hole 1311b can be directly arranged on the ground end 131b and / or the second feeding part 122a, or not directly arranged.

[0059] In this way, through the arrangement of the first conductive hole 1311a and the second conductive hole 1311b, the circuit board 1311 can be double-sided conductive, so as to avoid the need to wrap the power connection part 132 on the single-sided conductive surface when the single-sided conductive surface is arranged, and only need to arrange the circuit board 1311 between the antenna assembly 120 and the conductive part 131, which is beneficial to reduce the processing difficulty, and reduce the arrangement of other wires, which is beneficial to further reduce the thickness influence of the circuit board 1311 on the antenna glass assembly 100.

[0060] Among them, the first conductive hole 1311a and the second conductive hole 1311b can be metal conductive holes (that is, a metal coating is arranged on the hole wall of the conductive hole), or conductive holes with conductive glue (that is, a conductive glue layer is arranged on the hole wall of the conductive hole), which can be selected according to different production processes.

[0061] Optionally, in combination with the conductive glue in the above-mentioned embodiments, the conductive part 131 is electrically connected to the power connection part 132 through the conductive glue. Specifically, the first conductive hole 1311a is provided with the power connection end 131a, the second conductive hole 1311b is provided with the ground end 131b, and the power connection part 132 is directly bonded to the power connection end 131a and the ground end 131b through the conductive glue, which is beneficial to improve the contact stability of the conductive glue and the conductive part 131, thereby improving the connection stability of the conductive part 131 and the power connection part 132.

[0062] In addition, in combination with the coupling connection between the antenna assembly 120 and the conductive part 131 in the above-mentioned embodiments, the first conductive hole 1311a and the second conductive hole 1311b in the above-mentioned embodiments can not be directly arranged on the power connection end 131a or the power connection end 131a.

[0063] It should be noted that the first antenna unit 121 and the second antenna unit 122 can be but are not limited to patch antennas, and can also be slot antennas and the like, which are not limited here.

[0064] In combination with any one of the above-mentioned embodiments of the antenna assembly 120, referring to Figure 6The antenna assembly 120 includes a metal layer 123 (such as a silver paste coating or a copper paste coating, etc.) disposed on the glass substrate assembly 110. The first feeding portion 121a and the second feeding portion 122a are disposed on the metal layer 123. The first antenna unit 121 includes a first slot antenna 1211, and the second antenna unit 122 includes a second slot antenna 1221. The metal layer 123 is provided with a first slot 1231 for forming the first slot antenna 1211 and a second slot 1232 for forming the second slot antenna 1221. The first slot 1231 and the second slot 1232 are arranged in a spaced-apart manner, so that the first antenna unit 121 and the second antenna unit 122 are arranged in a spaced-apart manner.

[0065] It can be understood that the formation of the first slot 1231 and the second slot 1232 can enable the antenna assembly 120 to emit different antenna signals (antenna signals of different bandwidths, or antenna signals of different directions, etc.), so as to enrich the performance of the antenna assembly 120. In addition, the structure of the slot antenna is relatively simple, which is convenient to set and is beneficial to the processing of the antenna glass assembly 100.

[0066] In an embodiment, it is found that Figure 6 The length of the first slot 1231 is less than the length of the second slot 1232. In this way, by virtue of the length of the first slot 1231 being less than the length of the second slot 1232, the bandwidth of the first slot 1231 is greater than the bandwidth of the second slot 1232, so that the first slot antenna 1211 and the second slot antenna 1221 can emit radiation signals of different bandwidths, thereby enriching the radiation performance of the antenna assembly 120. At this time, the first slot antenna 1211 can form a lower frequency antenna and can emit a lower frequency radiation signal, and the second slot antenna 1221 can form a higher frequency antenna and can emit a higher frequency radiation signal. When the first slot antenna 1211 and the second slot antenna 1221 are coupled, a medium frequency radiation signal can be emitted.

[0067] In another embodiment, it is found that Figure 6, the first slot antenna 1211 has at least a first radiation direction, and the second slot antenna 1221 has at least a second radiation direction. The extension line of at least part of the first slot 1231 is arranged to intersect with the extension line of at least part of the second slot 1232. That is, at least part of the first slot 1231 and at least part of the second slot 1232 are arranged to intersect, and the intersection angle of the extension lines of the two can be any one, such as 30°, 60°, or 90°, etc. In this way, by arranging the extension line of at least part of the first slot 1231 to intersect with the extension line of at least part of the second slot 1232, the first radiation direction and the second radiation direction are arranged to intersect, thereby making the antenna assembly 120 have different radiation directions, expanding the radiation range of the antenna assembly 120, and thereby enriching the radiation performance of the antenna assembly 120.

[0068] In an example, the antenna assembly 120 is arranged to be mounted on a vehicle, and the first slot antenna 1211 and the second slot antenna 1221 are arranged to be mounted on the vehicle. Figure 6 , at least part of the first slot 1231 is arranged to extend along the length direction of the glass substrate assembly 110, and at least part of the second slot 1232 is arranged to extend along the width direction of the glass substrate assembly 110, so that the first radiation direction and the second radiation direction are arranged to be perpendicular. In this way, when the antenna assembly 120 is arranged on the vehicle, the antenna assembly 120 can realize signal radiation along the length direction and the width direction of the vehicle, thereby expanding the signal radiation range and enriching the antenna performance.

[0069] Further, in other embodiments, the antenna assembly 120 is arranged to be mounted on a vehicle, and the first slot antenna 1211 and the second slot antenna 1221 are arranged to be mounted on the vehicle. Figure 6 , the slot width of at least one of the first slot 1231 and the second slot 1232 is arranged to be unevenly distributed. In this way, when the slot width of the first slot 1231 and / or the second slot 1232 is unevenly distributed, the impedance of the first slot antenna 1211 and / or the second slot antenna 1221 can be adjusted, thereby optimizing the radiation performance of the antenna assembly.

[0070] , the slot width of the first slot 1231 and / or the second slot 1232 being unevenly distributed means that the slot width of the first slot 1231 and / or the second slot 1232 is not completely equal, and at least part of the slot width is greater than another part of the slot width.

[0071] Specifically, in a specific embodiment, the antenna assembly 120 is arranged to be mounted on a vehicle, and the first slot antenna 1211 and the second slot antenna 1221 are arranged to be mounted on the vehicle. Figure 6 , the second slot 1232 includes a first slot portion 1231a and a second slot portion 1231b, the first slot portion 1231a and the second slot portion 1231b are connected in communication, and the slot width of at least part of the first slot portion 1231a is smaller than the slot width of at least part of the second slot portion 1231b. The slot width of the first slot portion 1231a and the second slot portion 1231b can be uniformly distributed, or can be arranged to vary.

[0072] In another specific embodiment, the back view Figure 6 The second slot 1232 includes a third slot portion 1232a and a fourth slot portion 1232b. The third slot portion 1232a and the fourth slot portion 1232b are in communication, and the slot width of at least part of the third slot portion 1232a is smaller than the slot width of at least part of the fourth slot portion 1232b. The slot width of the third slot portion 1232a and the fourth slot portion 1232b can be uniformly distributed or can be set to vary.

[0073] Further, the back view Figure 6 The second slot 1232 further includes a fifth slot portion 1232c, one end of the fourth slot portion 1232b is in communication with the third slot portion 1232a, and the other end is in communication with the fifth slot portion 1232c. The slot width of at least part of the fifth slot portion 1232c is smaller than the slot width of at least part of the fourth slot portion 1232b. The slot width of the fifth slot portion 1232c can be uniformly distributed or can be set to vary. That is, in combination with the length of the second slot 1232 being greater than the length of the first slot 1231 in the above-mentioned embodiments, the frequency of the second antenna unit 122 is higher than the frequency of the first antenna unit 121 (for example, the second antenna unit 122 is a high-frequency antenna, and the first antenna unit 121 is a low-frequency antenna), so that the slot width of the second slot 1232 is greater than the slot width of the third slot portion 1232a and the fifth slot portion 1232c, so that at least part of the second slot 1232 has a slot width variation trend of narrow, wide, and narrow, which can improve the impedance of the second slot antenna 1221, and further improve the antenna performance of the second slot antenna 1221.

[0074] In addition, in an example, the back view Figure 7 to Figure 8 The slot width of at least part of the fourth slot portion 1232b is gradually expanded. In this way, by gradually expanding the slot width of the fourth slot portion 1232b, the second slot antenna 1221 can provide better impedance performance, and the width of the second slot antenna 1221 can gradually change, and in combination with the tuning ability of the metal layer 123, the bandwidth of each frequency band can be expanded, thereby realizing the ultra-wideband design of the antenna and greatly improving the communication performance.

[0075] It should be noted that in the above-mentioned embodiments, the length adjustment, slot width adjustment, or different setting direction of the first slot 1231 and the second slot 1232 can all enrich the radiation performance of the antenna assembly 120, and the above-mentioned embodiments can be arbitrarily combined, and will not be described in detail here.

[0076] The structure of the antenna glass assembly 100 in an example will be described below.

[0077] In an example, the overall size of the antenna glass can be 125mm*57mm, the slit width of the first slit 1231 is between 1mm~12mm, and the slit width of the second slit 1232 is between 3mm~32mm. The antenna glass assembly 100 is verified by testing, and the related results are shown in Figure 7 . Wherein, Figure 8 is a curve diagram of the relationship between the antenna frequency band and the standing wave ratio. Specifically, when the antenna frequency band is 700~960MHz, the standing wave ratio is less than 2.6; when the antenna frequency band is 1710~2690MHz, the standing wave ratio is less than 2.2; when the antenna frequency band is 3300~5000MHz, the standing wave ratio is less than 1.6. As can be seen, the overall standing wave ratio of the antenna glass assembly 100 in the above embodiment is greater than 1, which can meet the level of reflection, that is, the antenna glass assembly 100 in the above embodiment has good antenna radiation performance.

[0078] Further, as shown in Figure 8 , the curve diagram of the relationship between the antenna frequency band and the efficiency is shown in ​ . Specifically, when the antenna frequency band is 700~960MHz, the efficiency is about 50%; when the antenna frequency band is 1710~2690MHz, the efficiency is about 60%; when the antenna frequency band is 3300~5000MHz, the efficiency is about 55%. As can be seen, the overall efficiency of the antenna glass assembly 100 in the above embodiment is high, which means that sufficient radiation signals can be reflected and reflected quickly. The antenna glass assembly 100 in the embodiment has good antenna radiation performance.
