[0033] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0034] In this disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the relevant parts. In addition, the terms "first" and "second" are only used to distinguish and describe, and cannot be understood as indicating or implying relative importance.

[0035] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may be directly connected or indirectly connected through an intermediate medium, or they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0036] The antenna assembly generally needs to be mounted on a substrate to secure it. However, other structures often need to be mounted on the substrate, so holes may be opened at the connection between the substrate and the antenna assembly.

[0037] In related art, wireless signals emitted by antenna assemblies are easily transmitted outward through openings, affecting the stability of the wireless signals. This is particularly true for vehicle-mounted antennas, which are often mounted on the vehicle body, where wiring harnesses need to pass through. Therefore, vias are often provided at the antenna mounting location to allow the wiring harnesses to pass through.

[0038] For this reason, Figures 1-4 As shown, one aspect of the present disclosure provides an antenna assembly, including an antenna body 1 and a metal part 2, the antenna body 1 having a mounting portion 11, the mounting portion 11 being used to be mounted on a substrate 3, the metal part 2 being connected to the antenna body 1 and arranged on the mounting portion 11, the metal part 2 being configured to be able to block at least part of the wireless signal emitted by the antenna body 1 from being transmitted from the mounting portion 11 to the substrate 3.

[0039] Among them, the antenna body 1 can transmit wireless signals, and the installation part 11 is used to install the antenna component to the base 3 for fixation. Here, the base 3 can refer to the location where the antenna needs to be installed, and the specific structure is not too restricted.

[0040] In the above technical solution, the metal part 2 is set up to block the wireless signal emitted by the antenna body 1, that is, the wireless signal radiated toward the metal part 2 can be blocked so that it will not continue to radiate and transmit, so that the wireless signal emitted by the antenna body 1 will not be radiated outward through the mounting portion 11 and the vias on the substrate 3, and there will be no problem of wireless signal leakage, so that the wireless signal emitted by the antenna body 1 is radiated and transmitted in a direction away from the substrate 3, thereby ensuring the signal strength and stability of the antenna body 1.

[0041] Optionally, in one embodiment of the present disclosure, the metal member 2 is connected to the side of the mounting portion 11 facing the substrate 3. That is, the metal member 2 is located outside the antenna body 1 and connected to the outer wall of the mounting portion 11. When the mounting portion 11 is connected to the substrate 3, the metal member 2 is located between the mounting portion 11 and the substrate 3. This arrangement allows the metal member 2 to directly seal the vias in the substrate 3, thereby blocking wireless signals and enabling later installation, i.e., adjustment based on vehicle model changes.

[0042] Optionally, in one embodiment of the present disclosure, the metal member 2 is configured as a plate, wherein the metal member 2 is connected to the side of the mounting portion 11 facing the base 3 by screws, snaps, or heat-stitching. By configuring the metal member 2 as a plate, the thickness of the antenna assembly can be reduced to a minimum, allowing for installation at the original size.

[0043] Optionally, in another embodiment of the present disclosure, the metal member 2 is constructed as a metal coating, and the metal coating is applied to the side of the mounting portion 11 facing the substrate 3. The metal coating can be evenly covered on the side of the mounting portion 11 facing the substrate 3 by coating or spraying.

[0044] Alternatively, in another embodiment of the present disclosure, the metal member 2 is attached to the interior of the mounting portion 11. Specifically, the metal member 2 is located within the mounting portion 11, which may include a housing chamber. The metal member 2 is located within the housing chamber, making it invisible from the outside. This arrangement allows the metal member 2 to be concealed, preventing damage due to installation issues.

[0045] Optionally, in one embodiment of the present disclosure, the metal member 2 is configured as a plate, wherein the metal member 2 is connected to the interior of the mounting portion 11 by insert injection molding. By configuring the metal member 2 as a plate, the thickness of the antenna assembly can be increased without excessive increase, and the original size installation can be adapted.

[0046] Alternatively, in another embodiment of the present disclosure, the metal member 2 is connected to the side of the mounting portion 11 facing away from the substrate 3. That is, the metal member 2 is located inside the antenna body 1 and connected to the inner wall of the mounting portion 11. When the mounting portion 11 is connected to the substrate 3, the metal member 2 is located on the side of the mounting portion 11 facing away from the substrate 3. This arrangement allows the metal member 2 to remain within the antenna body 1, away from external exposure and interference from factors such as installation, thus preventing damage that could affect reliability.

[0047] Optionally, in one embodiment of the present disclosure, the metal member 2 is configured as a plate, wherein the metal member 2 is connected to the side of the mounting portion 11 facing away from the base 3 by screws, snaps, or heat-stitching. By configuring the metal member 2 as a plate, the arrangement and size of related structures within the antenna body 1 are not affected.

[0048] Optionally, in another embodiment of the present disclosure, the metal member 2 is constructed as a metal coating, and the metal coating is applied to the side of the mounting portion 11 facing away from the base 3. The metal coating can be evenly covered on the side of the mounting portion 11 facing away from the base 3 by coating or spraying.

[0049] Optionally, in one embodiment of the present disclosure, the antenna body 1 includes a shell 12 and a radiator 13, the metal part 2 and the radiator 13 are both connected in the shell 12, the metal part 2 is arranged opposite to at least part of the radiator 13, and a part of the shell 12 is set as the mounting part 11.

[0050] Among them, the shell 12 is used to accommodate the radiator 13, and the radiator 13 is used to emit wireless signals. The metal part 2 is connected to the inner wall of the shell 12 facing away from the base 3. The metal part 2 and the radiator 13 are arranged opposite to each other, which is conducive to blocking the wireless signals emitted by the radiator 13. The metal part 2 can block at least part of the wireless signals emitted by the radiator 13, which refers to the wireless signals radiated and transmitted toward the metal part 2, while the metal part 2 will not block the wireless signals in other directions. The shell 12 can protect the radiator 13 and the metal part 2.

[0051] Optionally, in one embodiment of the present disclosure, in the first direction, the length dimension of the metal part 2 is equal to or smaller than the length dimension of the mounting portion 11; and / or, in the second direction, the length dimension of the metal part 2 is equal to or smaller than the length dimension of the mounting portion 11.

[0052] The length of the metal member 2 in the first direction can be adjusted as needed. The length of the metal member 2 in the first direction can be equal to or less than the length of the mounting portion 11. The length of the metal member 2 in the second direction can also be adjusted as needed. The length of the metal member 2 in the second direction can be equal to or less than the length of the mounting portion 11. The first and second directions can be perpendicular. The first direction can be the length direction of the housing 12, and the second direction can be the width direction of the housing 12.

[0053] Optionally, in one embodiment of the present disclosure, metal member 2 includes an elongated plate 21. The length of elongated plate 21 in both the first and second directions is smaller than the length of mounting portion 11. Elongated plate 21 is configured to block low- and medium-frequency wireless signals emitted by antenna body 1. Providing a small elongated plate 21 can block low- and medium-frequency wireless signals emitted by antenna body 1, ensuring 5G signal transmission. This also prevents excessive weight of metal member 2 from being excessively large, affecting lightweight design, and reducing costs.

[0054] It can be understood that the metal part 2 is a structure of a long strip 21. In the first direction and the second direction, the length dimension of the long strip 21 is much smaller than the length dimension of the mounting part 11, and only occupies a small area of the mounting part 11. Therefore, the weight of the metal part 2 is relatively small and can meet the lightweight requirements.

[0055] Optionally, in one embodiment of the present disclosure, the frequency band of the medium and low frequency wireless signals emitted by the antenna body 1 is 1700Mhz-2600Mhz. By setting it in this way, 5G signal transmission can be met.

[0056] Since the vias opened on the substrate 3 affect the communication resonance of 1700Mhz-2600Mhz, the isolation of the antenna body 1 at this frequency will be insufficient, resulting in reduced antenna efficiency. Therefore, optionally, in one embodiment of the present disclosure, the metal part 2 also includes an isolation branch 22, the long strip 21 extends along the first direction, the isolation branch 22 extends along the second direction, one end of the isolation branch 22 is connected to the long strip 21, and the radiator 13 includes a first radiator 131 and a second radiator 132. In the first direction, the first radiator 131 and the second radiator 132 are spaced apart, and the isolation branch 22 is located between the first radiator 131 and the second radiator 132. The isolation branch 22 can be provided to isolate the first radiator 131 and the second radiator 132, thereby improving the isolation between the first radiator 131 and the second radiator 132, and improving the blocking effect on the wireless signals emitted by the first radiator 131 and the second radiator 132.

[0057] Optionally, in one embodiment of the present disclosure, one end of the isolation branch 22 is connected to the middle portion of the elongated plate 21 in the first direction, so that the isolation branch 22 and the elongated plate 21 form a "T" shape. The first direction and the second direction are perpendicular. This generates a resonance effect, shifting the resonant frequency to above 3000 MHz. This ensures improved isolation between the first radiator 131 and the second radiator 132, thereby enhancing antenna efficiency.

[0058] Optionally, in another embodiment of the present disclosure, one end of the isolation branch 22 is connected to one end of the long board 21 in the first direction, so that the isolation branch 22 and the long board 21 form an "L" shape, wherein the first direction and the second direction are perpendicular.

[0059] Optionally, in one embodiment of the present disclosure, the radiator 13 further includes a third radiator 133 and a fourth radiator 134. In the first direction, the third radiator 133 and the fourth radiator 134 are spaced apart, and the first radiator 131 and the second radiator 132 are located between the third radiator 133 and the fourth radiator 134. This arrangement enables the antenna body 1 composed of the first radiator 131, the second radiator 132, the third radiator 133, and the fourth radiator 134 to radiate 5G wireless signals and achieve communication.

[0060] In some examples, the third radiator 133 and the fourth radiator 134 are located at two ends of the housing 12 in the first direction, and the first radiator 131 and the second radiator 132 are close to the middle of the housing 12 in the first direction.

[0061] A second aspect of the present disclosure further provides a vehicle body structure comprising a vehicle body and the aforementioned antenna assembly, wherein the antenna assembly's mounting portion 11 is connected to the vehicle body. The antenna assembly is configured as a vehicle-mounted antenna, which can be mounted on the vehicle body as needed. It should be noted that the specific mounting location of the antenna assembly is not particularly limited herein.

[0062] Optionally, in one embodiment of the present disclosure, the vehicle body includes a crossbeam, the crossbeam is provided with a mounting groove 31 , the antenna assembly is disposed in the mounting groove 31 , and the mounting portion 11 of the antenna assembly is connected to the bottom of the mounting groove 31 .

[0063] Among them, the mounting groove 31 is used to install the antenna assembly, and the bottom of the mounting groove 31 is provided with a through hole for the wiring harness to pass through. After the antenna assembly is installed in the mounting groove 31, the antenna assembly can cover at least part of the through hole, wherein the metal part 2 of the antenna assembly can generate a barrier to the wireless signal emitted by the antenna body 1 from leaking and transmitting from the through hole, thereby ensuring the signal stability of the antenna assembly.

[0064] A third aspect of the present disclosure further provides a vehicle, comprising the above-mentioned antenna assembly or the above-mentioned vehicle body structure.

[0065] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings.
