[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0034] Please refer to Figure 1-Figure 7 A glass assembly includes a glass 100 and an antenna assembly 200; the antenna assembly 200 is arranged on one side of the glass 100 in the thickness direction. The antenna assembly 200 includes a circuit board 210, a cover 220 and a lid 230. The circuit board 210 is provided with an antenna, and the circuit board 210 has a wiring harness 211 extending to the outside of the circuit board 210; one side of the cover 220 in the length direction or width direction has an opening 221; a receiving cavity for accommodating the circuit board 210 is formed in the cover 220, and the circuit board 210 is detachably connected to the receiving cavity; the wiring harness 211 is detachably arranged through the cover 230, and the cover 230 can be interlocked with the opening 221. Preferably, the antenna assembly 200 is arranged on the inner side of the glass 100, and the cover 220 is bonded to the glass 100. Optionally, the cover 220 is connected to the circuit board 210 by snapping or sliding.

[0035] It is understood that by providing the separate cover 220 and lid 230, and by detachably connecting the cover 220 to the circuit board 210, the circuit board 210 can be embedded in the interior space of the cover 220, and the provision of the lid 230 allows the circuit board 210 to be locked between the cover 220 and the lid 230, thereby enabling the circuit board 210, the cover 220, and the lid 230 to maintain a stable positional relationship on the glass 100. The present invention utilizes the separate cover 220 and lid 230 to protect the circuit board 210 provided with the antenna, while also allowing the wiring harness 211 of the circuit board 210 to pass through the cover 230 and be electrically connected to the vehicle's internal wiring. This not only conceals the circuit board 210, but also protects it and reduces the difficulty of antenna maintenance.

[0036] In some embodiments, the cover 230 is provided with a wire channel 231 along the thickness of the circuit board 210 for the wire harness 211 to pass through. The wire harness 211 can pass through the wire channel 231 to electrically connect to the vehicle's internal circuitry. Therefore, the provision of the wire channel 231 not only ensures the structural stability of the housing, cover 220, and circuit board 210, but also ensures proper electrical connection of the circuit board 210. Furthermore, multiple wire channels 231 are provided, and the provision of multiple wire channels 231 can help organize the wire harness 211. Specifically, along the width of the cover 230, the two ends of the same wire channel 231 are interconnected.

[0037] In some embodiments, the distribution direction of the wire channel 231 forms an angle less than 90° with the length direction of the cover 230. This angle is formed to restrict the direction of the wire harness 211, so that the wire harness 211 is distributed along a specified direction and electrically connected to the corresponding external circuit, thereby protecting the wire harness 211. The angle can be designed according to the actual needs of the product.

[0038] In some embodiments, the circuit board 210 is preferably slidably connected to the housing 220. Slide grooves 223 are respectively provided on two opposing inner walls of the housing 220 in the thickness direction of the circuit board 210. The slide grooves 223 can interlock with the circuit board 210. Furthermore, the inner wall of the housing 220 is provided with limiting ribs 222. The limiting ribs 222 are arranged opposite the inner walls of the slide grooves 223 in the thickness direction of the circuit board 210. Preferably, the inner wall of the housing 220 can abut against the circuit board 210, improving the compatibility between the housing 220 and the circuit board 210. Furthermore, the slide grooves 223 provide a clearance fit with the circuit board 210. In other equivalent embodiments, a U-shaped groove can be provided on the inner wall of the housing 220 to allow the circuit board 210 to be inserted, thereby limiting the freedom of the housing 220 in the thickness direction of the circuit board 210.

[0039] In some embodiments, the side of the cover body 220 having the opening 221 is the open side; the open side of the cover body 220 has a first connecting portion 224 extending toward the side where the cover body 230 is located.

[0040] In some embodiments, the cover 230 includes a second connecting portion 232 disposed opposite the first connecting portion 224. The first connecting portion 224 and the second connecting portion 232 are detachably connected. Optionally, the first connecting portion 224 and the second connecting portion 232 are magnetically, snap-fit, or screw-connected. Preferably, the first connecting portion 224 and the second connecting portion 232 are threadedly connected by screws 240 to ensure a tight connection between the cover 220, the cover 230, and the circuit board 210.

[0041] In some embodiments, when the cover 230 is embedded in the opening 221 , part of the circuit board 210 is sandwiched between the first connection portion 224 and the second connection portion 232 , thereby improving the connection tightness between the circuit board 210 , the cover 230 , and the housing 220 .

[0042] In some embodiments, a through hole is provided on the first connecting portion 224, and a through hole is also provided on the second connecting portion 232. Through the cooperation between the first connecting portion 224 and the second connecting portion 232, the through holes on the first connecting portion 224 and the second connecting portion 232 are aligned, thereby enabling the screw 240 to sequentially connect with the first connecting portion 224, the circuit board 210, and the second connecting portion 232. Among them, at least the through hole on the second connecting portion 232 is a threaded through hole.

[0043] In some embodiments, a relief portion 225 protrudes from the side of the housing 220 away from the circuit board 210 in the thickness direction of the circuit board 210. Specifically, the relief portion 225 protrudes toward the side away from the circuit board 210 to increase the volume of the housing. The relief portion 225 is provided to provide space for other modules on the circuit board 210.
