The above definitions are only used to explain and illustrate the present invention and should not be construed as a limitation to the present invention.

[0045] See Figure 1 and Figure 2 , the first embodiment of the antenna assembly 1 of the present invention is invented.

[0046] See Figure 1 and Figure 2 , an antenna assembly 1 includes an antenna module 11 and a camera module 12. The camera module 12 includes a camera body 121, and the surface of the camera body 121 has a coating 122, and the coating 122 is for isolating electromagnetic interference between the antenna module 11 and the camera module 12.

[0047] In this embodiment, the surface of the camera body 121 has a coating 122. It should be noted in detail that the coating 122 material has excellent electromagnetic shielding performance and can effectively attenuate electromagnetic waves within a specific range. By selecting appropriate materials and thicknesses, efficient shielding of electromagnetic waves in a specific frequency band can be achieved.

[0048] In this embodiment, the antenna assembly 1 is a product integrating the antenna module 11 and the camera module 12, aiming to provide high-performance communication and imaging functions for electronic devices. At the same time, the coating 122 material on the surface of the camera body 121 has excellent electromagnetic shielding performance and can effectively attenuate electromagnetic waves within a specific range, ensuring no electromagnetic interference between the antenna module 11 and the camera module 12. When the antenna module 11 works, electromagnetic radiation will be generated. The coating 122 on the surface of the camera body 121 can absorb and reflect these electromagnetic waves, preventing them from entering the inside of the camera module 12, thereby avoiding interference with the imaging quality of the camera. At the same time, the coating 122 can also prevent the leakage of electromagnetic signals inside the camera module 12 from affecting the communication performance of the antenna module 11. The antenna assembly 1 is applicable to various electronic devices such as smart phones, tablet computers, and smart cars, and can effectively improve the communication quality and imaging effect of the devices.

[0049] See Figure 2 , the coating 122 is aluminum oxide, and the thickness of the coating 122 is 85 - 120 nm.

[0050] In this embodiment, the surface coating 122 process is changed from the original anodic oxidation of aluminum oxide with a thickness of about 10 μm to the conductive oxidation of aluminum oxide with a thickness of about 85 - 120 nm to achieve the passivation of the coating 122. And the present invention optimizes the style and process of the coating 122 on the surface of the camera body 121. Among them, the coating 11 is changed from the original black coating to a silver coating, making the conductivity of the camera body 121 better. By optimizing the conductivity of the camera body 121, current will flow inside the conductor to form so-called "eddy currents", and these currents will prevent the electromagnetic energy of the camera chip from penetrating into the space outside the cage. The interference of the camera body 121 is shielded, and through EMC (Electromagnetic Compatibility) verification, the electromagnetic interference problem caused by the small distance between the antenna module 11 and the camera module 12 is solved, and the positioning antenna module 11 and the rear panoramic camera module 12 can be arranged inside the antenna assembly 1 with a small space.

[0051] See Figure 3 and Figure 4 , the camera body 121 includes a front housing 1211 and a rear housing 1212; the front housing 1211 and the rear housing 1212 match, and the peripheries of the front housing 1211 and the rear housing 1212 are closed.

[0052] In this embodiment, the peripheries of the front housing 1211 and the rear housing 1212 are enclosed. It should be noted in detail that there are no holes or gaps at the mating part of the peripheries of the front housing 1211 and the rear housing 1212.

[0053] In this embodiment, when the distance between the high-precision positioning antenna assembly 11 and the rear panoramic camera module 12 is too small, there is an electromagnetic interference problem. Generally, the distance between the two main bodies is required to be more than 200 mm, and the clearance of the wire harness through-hole is more than 100 mm, which is difficult to be integrated into one antenna assembly. Through multiple tests of the present invention, it is determined that mainly the electromagnetic interference of the camera body 121 is strong, which affects the performance of the antenna. By optimizing the self-structure of the camera body 121, increasing the contact area between the front and rear housings 12 of the camera body 121, strengthening the conductivity of the camera and its own electromagnetic shielding; optimizing the housing process refers to improving the structure of the front housing 1211 of the camera body 121, because any discontinuity may become the entrance and exit of electromagnetic waves. Therefore, the present invention optimizes the structure to increase the contact area between the front and rear housings of the camera, improve the sealing performance, ensure that there are no holes or gaps, so that the camera body 121 itself forms a good Faraday cage, effectively improving the electromagnetic interference problem to the positioning antenna and reducing the influence of the electromagnetic of the camera body 121 itself on the positioning antenna.

[0054] See Figure 5 , the housing 12 includes a camera hole 131, and the camera hole 131 is located in the groove of the housing 12.

[0055] In this embodiment, the concave groove at the position of the camera hole 131 on the housing 12 is used to expose the lens of the camera body 121, which not only protects the lens and reduces the risk of lens scratching, but also can prevent rain and snow, and has low cost, reducing the problems of raindrop flow and snow covering on the lens surface in rainy and snowy weather, resulting in vision occlusion and unclear vision.

[0056] See Figure 3 , the camera module 12 further includes a mounting bracket 123 and a camera protective cover 124; the camera body 121 is mounted on the mounting bracket 123, and the mounting bracket 123 is arranged on the base 14; the camera protective cover 124 is used to protect the lens of the camera body 121.

[0057] In this embodiment, the camera body 121 is mounted on the mounting bracket 123, and the mounting bracket 123 is arranged on the base 14; the camera protective cover 124 is used to protect the lens of the camera body 121. It should be noted in detail that the mounting bracket 123 is first installed on the camera body 121 by screws, then the lens is aligned with the camera hole 131 on the housing 12, and finally the mounting bracket 123 is installed on the housing 12 by screws. The installation method here is not limited to screw fixation, and can also be adopted by means such as pasting, buckling or magnetic attraction.

[0058] In this embodiment, the camera assembly is installed at the rear of the housing 12. The rear-view camera has a higher requirement for imaging accuracy, so additional protection of the lens is required. The present invention designs a lens protection cover that can be directly installed on the front end of the lens.

[0059] See also Figure 6 and Figure 7 , the antenna assembly 1 further includes a first fastener 15; the base 14 includes a first mounting hole 141, the first fastener 15 passes through the first mounting hole 141, and the housing 12 and the base 14 are connected by the first fastener 15;

[0060] The antenna assembly 1 further includes a second fastener; the base 14 further includes a second mounting hole 142, the second fastener passes through the second mounting hole 142, and the base 14 and the vehicle body roof are connected by the second fastener;

[0061] The antenna assembly 1 further includes a third fastener 16 ; the third fastener 16 is integrated with the base 14 , and the base 14 and the vehicle body roof are connected via the third fastener 16 .

[0062] In this embodiment, it is necessary to explain in detail that, first, the installation of the base 14 and the vehicle body roof of the present invention is realized by the second fastener and the third fastener 16. One is that the base 14 is provided with the third fastener 16, and the third fastener 16 adopts a bolt structure from top to bottom, and the third fastener 16 is integrated on the base 14 and installed on the upper end of the rear cross beam of the vehicle body roof through a nut; the other is that the base 14 is provided with a second mounting hole 142, and the second fastener adopts a bolt structure from bottom to top, and the second fastener is punched on the base 14 from the inside of the vehicle body roof through the second mounting hole 142. Finally, the first mounting hole 141 includes a plurality of mounting points of the base 14 and the housing 12, and the first fastener 15 passes through the first mounting hole 141 to fix the base 14 and the housing 12; the number of the first mounting holes 141 and the type of the first fastener 15 are not limited here; the first mounting holes 141 can be 6, 8, etc., and the first fastener 15, the second fastener and the third fastener 16 are not limited to screw fixation, and can also be pasted, snapped or magnetically attracted.

[0063] In this embodiment, the sizes of the body roof and the roof space of different vehicle models are different, and the positions where bolts can be installed also vary. Therefore, the present invention provides two bolt mounting holes, namely the second mounting holes 142 in the present invention. The second mounting holes 142 can be one or two. Different vehicle models can match different mounting holes according to the roof structure, improving the versatility of the shark fin. Since the gap between the rear end of the mounting position of the antenna assembly 1 and the roof of the body is large and the acceptable bolt extension length is long, the second fastener adopts a bolt structure from bottom to top, which is convenient for positioning and installation at the same time. The invention further ensures the assembly convenience by means of optimizing the mounting point position, structure and assembly sequence, etc. For example, three mounting points are designed to match different arcs.

[0064] See Figure 8 , the antenna assembly further includes a gasket 17, and the gasket 17 is disposed between the base 14 and the body roof.

[0065] The gasket 17 includes a first sealing portion 171, and the first sealing portion 171 is a protrusion distributed along the edge of the base 14.

[0066] The gasket 17 further includes a third mounting hole 172 for exposing the third fastener 16.

[0067] The gasket 17 further includes a second sealing portion 173 and a third sealing portion 174. The second sealing portion 173 surrounds the first mounting hole 141, the second mounting hole 142, the third mounting hole 172 and the wire passing hole 143. The third sealing portion 174 is located between the second sealing portion 173 and the first mounting hole 141 or between the second sealing portion 173 and the second mounting hole 142 or between the second sealing portion 173 and the third mounting hole 172, and the third sealing portion 174 protrudes relative to the second sealing portion 173.

[0068] In this embodiment, it should be noted in detail that the gasket 17 can be made of rubber material. The first sealing portion 171 surrounds the entire outer circumference of the base and is in direct contact with the sheet metal of the body roof. The second sealing portion 173 surrounds each mounting hole of the first mounting hole 141, the second mounting hole 142 and the wire passing hole 143 of the base 14 for one week. The third sealing portion 174 is located above the base 14 and the mounting hole of the body roof, and its diameter is smaller than that of the second sealing portion.

[0069] In this embodiment, the base 14 and the body roof jointly act with three waterproof seals to ensure the waterproof performance of the body roof. At the same time, the third sealing portion 174 protrudes from the lowermost end of the base 14 and can be directly stuck in the mounting hole of the body roof.

[0070] See Figure 9 , the gasket 179 further includes a fourth sealing portion 175, and the fourth sealing portion 175 is disposed on the side away from the body roof, and the fourth sealing portion 175 wraps at least a part of the base 14.

[0071] In this embodiment, the fourth sealing portion 175 is disposed on the side away from the vehicle body roof. It should be noted in detail that the fourth sealing portion 175 is located on the side close to the housing 12.

[0072] Refer to Figure 9 , the housing 12 includes a first plate body 132. The first plate body 132 is disposed inside the housing 12, and the first plate body 132 abuts against the fourth sealing portion 175 to form an interference fit.

[0073] In this embodiment, the first plate body 132 is located inside the housing 12, which is realized by adding a raised structure inside the housing 12. The lowermost end of the first plate body 132 presses on the fourth sealing portion 175, making the sealing effect better. The two waterproof seals (the fourth sealing portion 175 and the first plate body 132) of the shark fin body act together to ensure the waterproof performance inside the shark fin.

[0074] The embodiment of the present invention also provides a vehicle, including the antenna assembly 1 described in any one of the above embodiments, which improves the signal transmission efficiency and quality of the antenna module 11 and reduces signal attenuation and distortion.
