[0032] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary.

[0033] The following refers to Figures 1-7 Describe the antenna assembly 100 according to an embodiment of the present utility model, which is applied to a vehicle.

[0034] As Figures 1-4As shown, the antenna assembly 100 according to the present utility model includes: an antenna box body 10 and an antenna board 20. A first limiting portion 11 is provided on the inner side of the antenna box body 10, and a second limiting portion 21 is provided on the side of the antenna board 20. The first limiting portion 11 and the second limiting portion 21 are in interference limiting fit, so that the antenna board 20 is detachably arranged in the antenna box body 10.

[0035] It can be understood that the antenna box body 10 and the antenna board 20 constitute the main structure of the antenna assembly 100. The antenna board 20 is arranged in the antenna box body 10, so that the antenna box body 10 can protect the antenna board 20, and further ensure the WIFI and Bluetooth functions of the antenna board 20, and also extend the service life of the antenna board 20.

[0036] Among them, the first limiting portions 11 are arranged on the left and right sides inside the antenna box body 10, and the second limiting portions 21 are arranged on the left and right sides of the antenna board 20. The first limiting portion 11 on the left and the second limiting portion 21 on the left are in limiting fit, and the first limiting portion 11 on the right and the second limiting portion 21 on the right are in limiting fit. Moreover, the first limiting portion 11 and the second limiting portion 21 are in interference fit. Such a setting can reduce the gap between the antenna board 20 and the antenna box body 10, and also make the connection between the antenna board 20 and the antenna box body 10 more stable, thereby saving the assembly steps between the antenna board 20 and the antenna box body 10, and facilitating the disassembly of the antenna board 20 relative to the antenna box body 10. Furthermore, it can save costs and facilitate the maintenance and repair of the antenna board 20.

[0037] For example, the length of the antenna box body 10 is 35.2 mm, the width is 21.3 mm, and the height is 14.8 mm. The length of the antenna board 20 is 32 mm, the width is 15 mm, and the height is 1.2 mm. Such a setting can ensure the function of the antenna board 20 and facilitate the installation of the antenna board 20 in the antenna box body 10, thereby reducing the gap between the antenna board 20 and the antenna box body 10. Moreover, the antenna assembly 100 weighs 8 g, which can not only achieve the lightweight design of the antenna assembly 100, but also facilitate the installation of the antenna assembly 100 on the vehicle body, and further facilitate the user to use the WIFI and Bluetooth functions. Moreover, after the antenna assembly 100 is installed on the vehicle body, during the vehicle road test, the noise of the antenna assembly 100 can be kept below 36 db, thereby improving the use experience of the passengers.

[0038] Therefore, by providing the first limiting portion 11 on the inner side of the antenna box body 10, the second limiting portion 21 on the side of the antenna board 20, and the first limiting portion 11 and the second limiting portion 21 being in interference limiting fit, the antenna board 20 can be detachably arranged in the antenna box body 10, and the assembly steps between the antenna board 20 and the antenna box body 10 can be saved, and the gap between the antenna board 20 and the antenna box body 10 can be prevented from being generated, thereby saving material costs and labor costs.

[0039] Among them, as Figures 1-4 shown, there are at least two first limiting portions 11. The first limiting portion 11 includes: a carrier 12 and a stopper 13. The carrier 12 is disposed inside the antenna box body 10 and is oppositely disposed along the width direction of the antenna box body 10. The antenna board 20 is disposed on the carrier 12. The stopper 13 is disposed inside the antenna box body 10 and is located on the side of the carrier 12 close to the antenna board 20. The stopper 13 and the second limiting portion 21 are in interference limiting fit.

[0040] It can be understood that the two first limiting portions 11 are located on the left and right sides inside the antenna box body 10. The first limiting portion 11 on the left side is in limiting fit with the second limiting portion 21 on the left side, and the first limiting portion 11 on the right side is in limiting fit with the second limiting portion 21 on the right side. Moreover, the first limiting portion 11 and the second limiting portion 21 are in interference fit. Such a setting can reduce the gap between the antenna board 20 and the antenna box body 10, and can also make the connection between the antenna board 20 and the antenna box body 10 more stable. Thus, the assembly steps between the antenna board 20 and the antenna box body 10 can be saved, and it is also convenient for the disassembly of the antenna board 20 relative to the antenna box body 10. Furthermore, the cost can be saved, and it is convenient for the maintenance and repair of the antenna board 20.

[0041] In addition, the carrier 12 and the stopper 13 constitute the main structure of the first limiting portion 11. The carrier 12 is located at the bottom of the antenna box body 10. In this way, the lower side of the second limiting portion 21 can be in abutting fit with the carrier 12, so that the antenna board 20 can be disposed on the carrier 12. Furthermore, the carrier 12 can bear the weight of the antenna board 20. Moreover, the carrier 12 is located on the left and right sides inside the antenna box body 10, so that the antenna board 20 can be more stable in the left and right directions inside the antenna box body 10, and the gap between the lower side of the antenna board 20 and the antenna box body 10 can also be reduced. The stopper 13 is located between the left and right sides of the carrier 12 and the antenna box body 10, and the upper end of the stopper 13 is higher than the upper surface of the carrier 12. Such a setting can make the stopper 13 located between the antenna board 20 and the antenna box body 10, so that the stopper 13 can reduce the gap between the left and right sides of the antenna board 20 and the antenna box body 10, and further make the antenna board 20 more stable inside the antenna box body 10.

[0042] Particularly, as Figure 3 and Figure 4As shown, the cross-section of one of the stoppers 13 is triangular, and the cross-section of the other stopper 13 is rectangular. It can be understood that the cross-sections of the stoppers 13 on the left and right sides inside the antenna box body 10 are different. The cross-section of the stopper 13 on the left side is rectangular, and the cross-section of the stopper 13 on the right side is triangular, or the cross-section of the stopper 13 on the left side is triangular, and the cross-section of the stopper 13 on the right side is rectangular. The second limiting portion 21 is first in limiting cooperation with the stopper 13 with a rectangular cross-section, and then in interference fit with the stopper 13 with a triangular cross-section. Such a setting can simplify the steps of installing the antenna board 20 inside the antenna box body 10, and can also prevent the antenna board 20 from shaking in the left-right direction inside the antenna box body 10, thereby saving material costs and labor costs.

[0043] In addition, as Figures 1-7 shown, the antenna box body 10 includes: a first box body 14 and a second box body 15. A first clamping portion 141 is provided on the outer side of the first box body 14, and a second clamping portion 151 is provided on the outer side of the second box body 15. The first clamping portion 141 and the second clamping portion 151 are in clamping cooperation. That is to say, the first box body 14 and the second box body 15 form the main structure of the antenna box body 10. The first clamping portions 141 are provided on the left and right sides of the first box body 14, and the second clamping portions 151 are provided on the left and right sides of the second box body 15. The first clamping portion 141 and the second clamping portion 151 are in clamping cooperation, so that the first box body 14 and the second box body 15 are convenient to disassemble and install, and further, the installation steps of the antenna box body 10 can be saved, as well as material costs and labor costs.

[0044] Optionally, as Figure 5 and Figure 6 shown, one of the first clamping portion 141 and the second clamping portion 151 is a clamping protrusion, and the other of the first clamping portion 141 and the second clamping portion 151 is a clamping groove. The clamping protrusion and the clamping groove are selectively in clamping cooperation. It can be understood that the first clamping portion 141 can be a clamping protrusion, and the second clamping portion 151 can be a clamping groove, or the first clamping portion 141 can be a clamping groove, and the second clamping portion 151 can be a clamping protrusion. The clamping protrusion and the clamping groove are in clamping cooperation, so that the first box body 14 and the second box body 15 are convenient to disassemble and install, and further, the installation steps of the antenna box body 10 can be saved, as well as material costs and labor costs.

[0045] Among them, as Figure 1As shown, an installation space is formed between the first box body 14 and the second box body 15. The antenna board 20 is disposed in the installation space, and the first limiting portion 11 is disposed on the second box body 15. That is to say, the first box body 14 and the second box body 15 are disposed opposite to each other up and down, so that an installation space can be formed between the first box body 14 and the second box body 15, so that the antenna board 20 can be disposed in the installation space. This can not only protect the antenna board 20 by the antenna box body 10, but also ensure the function of the antenna board 20. The first limiting portion 11 is located on the left and right sides inside the second box body 15, and the first limiting portion 11 and the second limiting portion 21 are in limiting cooperation, so that the antenna board 20 can be disposed in the second box body 15. Then, the first clamping portion 141 and the second clamping portion 151 are in clamping cooperation, and further the antenna board 20 can be installed in the antenna box body 10.

[0046] In addition, as Figure 6 shown, an abutting portion 16 is disposed on the inner side of the first box body 14, and the abutting portion 16 abuts against one side of the antenna board 20. It can be understood that the abutting portion 16 is disposed on the side of the first box body 14 facing the second box body 15, the abutting portion 16 is located above the antenna board 20, and the abutting portion 16 and the upper surface of the antenna board 20 are in abutting cooperation, so as to reduce the gap between the antenna board 20 and the first box body 14, and further make the antenna board 20 more stable in the antenna box body 10. For example, the abutting portion 16 is a limiting rib, and there are multiple limiting ribs, which can not only increase the abutting area between the limiting rib and the antenna board 20, but also improve the structural strength of the antenna box body 10, so that the antenna board 20 is more stable in the antenna box body 10, and further ensure the function of the antenna assembly 100.

[0047] In addition, as Figure 1 shown, an avoidance opening 17 is disposed on one side of the first box body 14 to avoid the wire harness, and the wire harness is electrically connected to the antenna board 20. That is to say, an avoidance opening 17 is formed on one side of the first box body 14, so that the wire harness can be electrically connected to the antenna board 20 through the avoidance opening 17, so as to ensure the function of the antenna board 20, and further simplify the connection between the antenna assembly 100 and the wire harness.

[0048] In addition to this, as Figure 1 and Figure 7As shown, the antenna assembly 100 further includes: a fixing member 30. The fixing member 30 is disposed on the outer side of the second box body 15 away from the first box body 14. A sliding groove 18 is provided on the outer side of the second box body 15. The fixing member 30 is slidably engaged with the sliding groove 18, and the fixing member 30 is disposed on the vehicle body. It can be understood that the fixing member 30 is located below the second box body 15, and the sliding groove 18 is provided below the second box body 15. The fixing member 30 can move within the sliding groove 18, so as to facilitate the fixing member 30 to be assembled to the antenna box body 10 through the sliding groove 18. The fixing member 30 can be installed on the vehicle body, so that the antenna assembly 100 can be disposed on the vehicle body, and further facilitate the use of the antenna assembly 100 by the driver and passengers. For example, the fixing member 30 is a snap flower, which not only facilitates the snap flower to connect to the antenna box body 10 through the sliding groove 18, but also facilitates the snap flower to be disposed on the vehicle body, thereby ensuring the function of the antenna assembly 100.

[0049] In particular, as Figure 1 shown, the antenna board 20 is a printed circuit board, and the printed circuit board is provided with a WIFI connector and / or a Bluetooth connector. Such a setting facilitates the installation of the antenna board 20 in the antenna box body 10. In addition, the antenna board 20 has WIFI and Bluetooth functions, so as to facilitate the driver and passengers to use the WIFI and Bluetooth functions of the antenna assembly 100.
