Description

Support components, antenna devices and base stations

[0001] This application claims priority to Chinese Patent Application No. 202422661164.0, filed on October 31, 2024, entitled “Support Member, Antenna Device and Base Station”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and in particular to a support, antenna device and base station. Background Technology

[0003] Support components are crucial parts of antenna devices. They support the radome, protecting the internal structure from damage caused by static pressure, stepping, impacts, or pushing / pulling of the radome. Support components can also support the frequency selector surfaces inside the antenna device to meet various electrical requirements. However, existing support components are complex in structure and expensive to manufacture. Summary of the Invention

[0004] This application provides a support member, an antenna device, and a base station. The support member of this application has a simple structure, high structural strength, and low cost.

[0005] In a first aspect, embodiments of this application provide a support member applied to an antenna device. The support member includes a carrier portion, a first connecting portion, and a second connecting portion. The first connecting portion is fixedly connected to one end of the carrier portion, and the second connecting portion is fixedly connected to the other end of the carrier portion. The carrier wall of the carrier portion is the external wall of the support member, and the carrier wall encloses a hollow cavity. Understandably, the carrier wall is a structure visible from the outside of the support member.

[0006] The embodiments of this application, by setting a bearing wall and forming a hollow cavity around it, make the structure of the support simple while ensuring high structural strength and large supporting force. This helps to reduce the material used in the support, making the support lighter and reducing its manufacturing cost.

[0007] In one possible implementation, the hollow cavity extends from one end of the supporting portion to the other end. By extending the hollow cavity from one end of the supporting portion to the other end, the material used in the support component can be effectively reduced, the structural complexity of the support component can be decreased, and the manufacturing cost of the support component can be reduced.

[0008] In a possible implementation, the thickness of the bearing wall is greater than or equal to 1 mm and less than or equal to 3 mm. By setting the thickness of the bearing wall to be greater than or equal to 1 mm and less than or equal to 3 mm, it is beneficial to ensure the structural strength of the support member and achieve the lightweight of the support member. If the thickness of the bearing wall is less than 1 mm, the bearing wall is relatively thin and the structural strength of the support member is low. If the thickness of the bearing wall is greater than 3 mm, the bearing wall is relatively thick, more materials are used, and the cost is high.

[0009] In a possible implementation, the cross-section of the bearing part is square, trapezoidal, circular, fan-shaped or "day" shaped. By setting the cross-section of the bearing part to be square, trapezoidal, circular, fan-shaped or "day" shaped, the stress area of the bearing part can be effectively increased, the bearing part can have a larger moment of inertia, and the bearing part can have better load performance, such as bending resistance and compression resistance.

[0010] In a possible implementation, the areas of any two cross-sections of the bearing part are equal. By setting the areas of any two cross-sections of the bearing part to be equal, the structure of the bearing part is simple, which is beneficial to reducing the manufacturing difficulty of the bearing part, simplifying the manufacturing process of the bearing part to reduce the manufacturing cost. In addition, the equal areas of any two cross-sections of the bearing part result in good uniformity of the appearance size of the bearing part and good visual effect.

[0011] In a possible implementation, the bearing part includes a first cross-section and a second cross-section, the first cross-section and the second cross-section are arranged along the extension direction of the bearing part, and the area of the first cross-section is not equal to the area of the second cross-section. The area of the cross-section of the bearing part can be adaptively adjusted according to the different stress conditions in different regions of the bearing part, so as to improve the flexibility of the design of the bearing part.

[0012] In a possible implementation, the bearing part includes a first section, a second section and a third section arranged in sequence, the first cross-section is the cross-section of the second section, the second cross-section is the cross-section of the first section or the third section, the area of the cross-section of the first section is less than the area of the cross-section of the second section, and the area of the cross-section of the third section is less than the area of the cross-section of the second section. By setting the area of the cross-section of the second section to be larger, it is beneficial to improve the reliability of the structure of the bearing part. It can be understood that the area of the cross-section of the first section and the area of the cross-section of the third section can be equal or not equal.

[0013] In a possible implementation, the bearing part is in an arc shape, or the bearing part is in a semi-circular shape, or the bearing part is in a flat plate shape. The shape of the bearing part can be adapted to the shape of the supported structure, and the shape of the bearing part can be set according to needs, with high flexibility.

[0014] In one possible implementation, the support component is a one-piece molded structure. A one-piece molded support component has better structural strength and a simpler manufacturing process.

[0015] In one possible implementation, the first connecting part is detachably connected to the support part, and / or the second connecting part is detachably connected to the support part, which helps to improve the connection flexibility between the first connecting part, the second connecting part and the support part.

[0016] In one possible implementation, the first connecting portion includes an abutting structure located outside the supporting portion. The abutting surface of the abutting structure abuts against the supporting portion, and the abutting surface of the supporting portion is covered by a portion of its projection on the abutting surface. By providing an abutting surface that covers a portion of the supporting portion's projection on the abutting surface—in other words, by making the size of the abutting surface larger than the size of the end face of the supporting portion—it is beneficial to improve the support of the abutting structure for the supporting portion and to improve the connection reliability between the first connecting portion and the supporting portion. It is understood that in some other implementations, the size of the abutting surface may also be smaller than or equal to the size of the end face of the supporting portion.

[0017] In one possible implementation, a portion of the first connecting portion is embedded in the carrier portion, and / or a portion of the second connecting portion is embedded in the carrier portion. By providing that the first connecting portion can be embedded in the carrier portion and that a portion of the second connecting portion can be embedded in the carrier portion, the reliability and strength of the connection between the first connecting portion and the second connecting portion and the carrier portion can be improved.

[0018] In one possible implementation, the first connecting portion is provided with an embedding structure, the embedding structure including a main body and an elastic body fixed to the main body, the bearing wall having a mounting hole, the main body being embedded in the bearing portion, and the elastic body being embedded in the mounting hole. By providing the elastic body embedded in the mounting hole, a detachable connection between the first connecting portion and the bearing portion can be achieved, which is beneficial to improving the reliability of the connection between the first connecting portion and the bearing portion.

[0019] In one possible implementation, the load-bearing portion includes at least two sub-load-bearing portions, and the support member includes a third connecting portion that connects two adjacent sub-load-bearing portions. By providing the third connecting portion, the load-bearing portion can be supported, which helps improve the reliability of the support member.

[0020] In one possible implementation, the support member is made of thermoplastic or metal.

[0021] In one possible implementation, the support is made of acrylonitrile-butadiene-styrene plastic, polycarbonate, polypropylene, polyethylene, aluminum, iron, or copper.

[0022] Secondly, this application provides an antenna device, including an antenna radome and a support member as described in any of the foregoing embodiments, the support member supporting the antenna radome.

[0023] Thirdly, this application provides an antenna device, the antenna device including an radome, a frequency selective surface and a support member as described in any of the foregoing embodiments, the support member supporting the radome, and / or the support member supporting the frequency selective surface.

[0024] Fourthly, this application provides a base station including the antenna device described in any of the foregoing embodiments, wherein the antenna device is used to transmit signals from the base station. Attached Figure Description

[0042] The embodiments of this application are described below with reference to the accompanying drawings.

[0043] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" refers to at least two.

[0044] The directional terms mentioned in the embodiments of this application, such as "upper", "inner", "outer", "side", etc., are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0045] In the embodiments of this application, the relative positional relationships mentioned, such as parallel or perpendicular, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees.

[0046] In the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0047] Please refer to Figure 1, which illustrates an application scenario of wireless communication between a base station 100 and a terminal device 200 according to an embodiment of this application. This application provides a wireless communication system 1000, which may include a base station 100 and a terminal device 200. Wireless communication is possible between the base station 100 and the terminal device 200; that is, communication can be achieved by transmitting information between the base station 100 and the terminal device 200 in the form of electromagnetic waves (also known as electromagnetic radiation) without any physical connection, such as wires or cables.

[0048] Base station 100 can be any device with wireless transceiver function. For example, base station 100 can be a base transceiver station in a Global System for Mobile Communications (GSOM) or Code Division Multiple Access (CDMA) system, or a wireless controller in a cloud wireless access network scenario.

[0049] Terminal device 200 is a device with wireless transceiver capabilities. As shown in Figure 1, terminal device 200 can be a mobile phone. In other embodiments, terminal device 200 can also be a tablet computer, smartwatch, smart glasses, computer, virtual reality terminal device, augmented reality terminal device, terminal in industrial control, vehicle terminal device, terminal device in autonomous driving, terminal device in assisted driving, terminal device in telemedicine, terminal device in smart grid, terminal device in transportation safety, terminal device in smart city, terminal device in smart home, etc. Furthermore, terminal device 200 can be fixed or mobile; it can be deployed on land, on water (such as a ship), or in the air (such as on an airplane, balloon, or satellite). This application does not limit the form, location, or number of terminal devices 200.

[0050] It is understood that the location, number, and form of the base station 100 and terminal device 200 shown in Figure 1 are only schematic representations, and the embodiments of this application do not limit them.

[0051] Please refer to Figure 2, which is a structural schematic diagram of an antenna device 10 provided in an embodiment of this application. The base station 100 may include the antenna device 10, which can be used to transmit signals in space, ensuring network signal coverage within a preset area.

[0052] The antenna device 10 may include an antenna array (not shown in Figure 2), which can be used to radiate and receive antenna signals. The antenna array may include a plurality of radiating elements (not shown in Figure 2) arranged in a certain pattern. Each radiating element can radiate and receive electromagnetic waves to realize the transmission and reception functions of the antenna device 10. The operating frequency bands of the multiple radiating elements may be the same or different, and this embodiment of the application does not limit this.

[0053] The antenna device 10 may include a reflector 11, and the radiating elements may be fixedly connected to the reflector 11. The reflector 11 may also be called a base plate, antenna panel, or reflective surface, etc. The reflector 11 may be made of, for example, a metal material. When the radiating element receives an antenna signal, the reflector 11 can reflect the antenna signal onto the receiving point, thereby achieving directional reception of the antenna signal; when the radiating element transmits an antenna signal, the reflector 11 can achieve directional transmission of the antenna signal. By setting the reflector 11, the ability of the radiating element to receive or transmit antenna signals can be enhanced. This application embodiment does not limit the number or position of the radiating elements on the reflector 11.

[0054] Referring to Figure 2, the antenna device 10 may include an radome 12, which can be fixedly connected to a reflector 11. Exemplarily, the antenna device 10 may include a bracket (not shown in Figure 2), which can be fixedly connected to the reflector 11, and the radome 12 can be fixedly connected to the reflector 11 via the bracket. The antenna array may be located on the side of the radome 12 facing the reflector 11; in other words, the radome 12 may cover the antenna array. It is understood that the base station 100 is often located outdoors, and outdoor environmental factors such as storms, snow, dust storms, and solar radiation may affect the antenna performance of the antenna device 10, thereby affecting the communication quality of the wireless communication system 1000. By providing the radome 12, the structure (e.g., the antenna array) located within it can be protected, which helps to reduce the impact of the outdoor environment on the antenna array's radiation or received antenna signals, and can reduce the impact of environmental factors on the performance of the antenna device 10.

[0055] Understandably, the radome 12 can be made of materials such as plastic. In the embodiments of this application, the radome 12 may include a first part 121 and a second part 122, the first part 121 and the second part 122 may form an integral structure, and the reflector 11 may be located within the space enclosed by the first part 121 and the second part 122.

[0056] Referring to Figure 2, the antenna device 10 may include a support member 13, which can be fixedly connected to the reflector 11. The support member 13 can support the radome 12 and can be located on the side of the radome 12 facing the reflector 11, between the antenna array and the radome 12. By providing the support member 13, the radome 12 can be supported by the support member 13, which can effectively prevent damage to the antenna array caused by static pressure (the pressure of the upper antenna device 10 on the packaging of the lower antenna device 10 and the radome 12 when the packaged antenna devices 10 are stacked together), stepping, bumping, or pushing and pulling the radome 12. The support member 13 can prevent the radome 12 from impact, thus improving the reliability of the antenna device 10. The support member 13 can be connected to the reflector 11 by means of snap-fit, screw, sleeve, or adhesive, etc., which is not limited in this embodiment.

[0057] In some other embodiments, the support member 13 may also be used to support other structural components of the antenna device 10 (e.g., the frequency selective surface 14 described later in FIG. 9), and the support member 13 may also be located between the frequency selective surface 14 and the reflector 11. It is understood that the support member 13 may support the radome 12, or the support member 13 may support the frequency selective surface 14, or some support members 13 may support the radome 12 while others support the frequency selective surface 14.

[0058] The number of support members 13 can be one, two, three or more, and multiple support members 13 can be spaced apart along the length direction of the reflector 11 (from the perspective shown in FIG. 2). The support members 13 on opposite sides of the reflector 11 can be symmetrically distributed with the reflector 11 as the axis of symmetry. For example, two support members 13 on opposite sides of the reflector 11 can be connected to opposite sides of the reflector 11 through different adapters to avoid conflict in the installation positions of the two support members 13 on the reflector 11. Alternatively, the support members 13 on opposite sides of the reflector 11 can also be staggered. The embodiments of this application do not limit the number, shape, position, etc. of the support members 13.

[0059] Please refer to Figures 2 to 5A. Figure 3 is a partial structural schematic diagram of the antenna device 10 shown in Figure 2. Figure 4 is a structural schematic diagram of the support member 13 shown in Figure 3. Figure 5A is a cross-sectional structural schematic diagram of the support member 13 shown in Figure 3 at point AA.

[0060] The support member 13 may include a carrier portion 131, a first connecting portion 132, and a second connecting portion 133. The carrier portion 131 can be used to support the radome 12, and the shape of the carrier portion 131 can be adapted to the shape of the radome 12. For example, taking the first portion 121 as an example, the shape of the first portion 121 can be arc-shaped, and the shape of the carrier portion 131 can also be arc-shaped; for example, the shape of the first portion 121 can be semi-circular, and the shape of the carrier portion 131 can also be semi-circular; for another example, the shape of the first portion 121 can also be flat, and correspondingly, the shape of the carrier portion 131 can also be flat, so as to increase the contact area between the carrier portion 131 and the radome 12, thereby improving the support effect of the support member 13 on the radome 12. In some other embodiments, the shape of the carrier portion 131 may also be different from the shape of the first portion 121 and / or the second portion 122. The embodiments of this application do not limit the shape and size of the radome 12, or the shape and size of the support member 13.

[0061] Referring to Figure 5A, the support portion 131 may include a support wall 1311, which is the exterior wall of the support member 13; in other words, the support wall 1311 is a structure visible from the outside of the support member 13. The support wall 1311 may enclose a hollow cavity 1312; in other words, the support portion 131 is a hollow structure. Exemplarily, the hollow cavity 1312 may extend from one end of the support portion 131 to the other end. It is understood that the support portion 131 may be a structure closed at both ends; in other words, the hollow cavity 1312 is isolated from the external space. Alternatively, the support portion 131 may have openings at both ends, allowing the hollow cavity 1312 to communicate with the external space of the support portion 131 through the openings at the ends of the support portion 131. This application embodiment does not limit the structure of the support portion 131. It is understood that a reinforcing structure may be provided within the hollow cavity 1312 to increase the structural strength of the support portion 131.

[0062] The first connecting portion 132 can be fixedly connected to one end of the supporting portion 131, and the second connecting portion 133 can be fixedly connected to the other end of the supporting portion 131. The first connecting portion 132 and the second connecting portion 133 can be fixed to the supporting portion 131 by means of adhesive, screws, or snap-fit. Understandably, the first connecting portion 132 and the second connecting portion 133 can be detachably fixedly connected to the supporting portion 131, allowing for high flexibility in the connection between the first connecting portion 132 and the second connecting portion 133 and the supporting portion 131. Alternatively, the first connecting portion 132 and the second connecting portion 133 can be non-detachably fixedly connected to the supporting portion 131; this embodiment does not limit this. In other embodiments, the first connecting portion 132, the supporting portion 131, and the second connecting portion 133 can also be an integrally formed structure. In some other embodiments, the first connecting portion 132 and the second connecting portion 133 may also be connected as a single unit. For example, the support member 13 may further include a connecting plate that connects the first connecting portion 132 and the second connecting portion 133 as a single unit. Alternatively, the first connecting portion 132 and the second connecting portion 133 may be an integrally formed structure.

[0063] In this embodiment, the bearing wall 1311 can play a supporting role. By setting the bearing wall 1311 and forming a hollow cavity 1312, the moment of inertia of the cross section of the bearing part 131 is relatively good, which makes the structure of the support member 13 simpler and ensures that the structural strength and supporting force of the support member 13 are high. The material utilization rate is high, which is conducive to reducing the material used in the support member 13. The weight of the support member 13 is small, which is conducive to realizing the lightweight of the support member 13 and reducing the manufacturing cost of the support member 13.

[0064] By setting the hollow cavity 1312 to extend from one end of the support portion 131 to the other end of the support portion 131, the material used in the support member 13 can be effectively reduced, the structural complexity of the support member 13 can be reduced, and the manufacturing cost of the support member 13 can be reduced.

[0065] The supporting wall 1311 may include an inner surface 13111 and an outer surface 13112. The inner surface 13111 is the surface facing the hollow cavity 1312, and the outer surface 13112 is the surface facing away from the hollow cavity 1312. The outer surface 13112 surrounds the inner surface 13111. The thickness L1 of the supporting wall 1311 can be understood as the distance between the inner surface 13111 and the outer surface 13112.

[0066] In some embodiments, the thickness L1 of the bearing wall 1311 can be greater than or equal to 1 mm and less than or equal to 3 mm. For example, the thickness L1 of the bearing wall 1311 can be 1.5 mm, 2 mm, or 2.5 mm, etc. Setting the thickness L1 of the bearing wall 1311 to be greater than or equal to 1 mm and less than or equal to 3 mm is beneficial to ensuring the structural strength of the support member 13 and achieving the lightweight of the support member 13. If the thickness L1 of the bearing wall 1311 is less than 1 mm, the bearing wall 1311 is thinner, and the structural strength of the support member 13 is lower. If the thickness L1 of the bearing wall 1311 is greater than 3 mm, the bearing wall 1311 is thicker, requiring more material and resulting in higher costs. In some other embodiments, the thickness L1 of the bearing wall 1311 can also be less than 1 mm or greater than 3 mm, and this application embodiment does not limit this.

[0067] The thickness L1 of the supporting wall 1311 can be equal or unequal at various points. That is, the distance between the inner surface 13111 and the outer surface 13112 of the supporting wall 1311 can be equal or unequal at any two points. For example, the cross-section of the area enclosed by the inner surface 13111 of the supporting wall 1311 can be circular, and the cross-section of the area enclosed by the outer surface 13112 of the supporting wall 1311 can be square. In this case, the thickness L1 of the supporting wall 1311 is unequal. Here, "cross-section" refers to the section perpendicular to the extending direction of the supporting portion 131.

[0068] Please refer to FIG. 5A. In some embodiments, the cross-section of the bearing portion 131 can be square, and the square can also be understood as a "mouth" shape. Here, the cross-section of the bearing portion 131 being square means that the cross-section of the area surrounded by the outer surface 13112 of the bearing portion 131 can be square. For example, the cross-section of the bearing portion 131 can be rectangular or square. Exemplarily, the cross-section of the bearing portion 131 can include a first side 1311a, a second side 1311b, a third side 1311c, and a fourth side 1311d. The first side 1311a can be parallel to the second side 1311b, and the first side 1311a can be closer to the supported member of the antenna device 10 (such as, the radome 12 or the frequency selective surface 14) than the second side 1311b. Both the third side 1311c and the fourth side 1311d are connected between the first side 1311a and the second side 1311b and are located at opposite ends of the first side 1311a. The first side 1311a, the third side 1311c, the second side 1311b, and the fourth side 1311d surround and form a square. When the support member 13 supports the radome 12, the first side 1311a is used to contact the radome 12, and the third side 1311c and the fourth side 1311d can be used to disperse and bear the pressure of the radome 12 on the bearing portion 131. By setting the cross-section of the bearing portion 131 to be square, the stress area of the bearing portion 131 can be effectively increased, and the bearing portion 131 can have a relatively large moment of inertia, so that the bearing portion 131 can have better load performance, such as bending resistance, compression resistance, etc. In some other embodiments, the cross-section of the bearing portion 131 can also be approximately in the shape of a "day" character, fan shape, circular shape, trapezoidal shape, pentagonal shape, hexagonal shape, etc., and the embodiments of the present application do not limit this.

[0069] For example, when the cross-section of the bearing part 131 is approximately trapezoidal, the first side 1311a can be parallel to the second side 1311b, and the length of the first side 1311a is less than that of the second side 1311b. The first side 1311a is closer to the radome 12 or the frequency selective surface 14 of the antenna device 10 (as shown in FIG. 9) than the second side 1311b. In other words, the first side 1311a contacts the radome 12 or the frequency selective surface 14, and the second side 1311b is farther from the radome 12 or the frequency selective surface 14 than the first side 1311a. The included angle between the third side 1311c and the first side 1311a is an obtuse angle, the included angle between the third side 1311c and the second side 1311b is an acute angle, the included angle between the fourth side 1311d and the first side 1311a is an obtuse angle, and the included angle between the fourth side 1311d and the second side 1311b is an acute angle. At this time, the bearing part 131 can also have a relatively large moment of inertia and load performance. By setting the first side 1311a closer to the radome 12 or the frequency selective surface 14 of the antenna device 10 than the second side 1311b, the force received by the radome 12 or the frequency selective surface 14 is transmitted to the smaller-sized first side 1311a, and the force of the smaller-sized first side 1311a is transmitted to the larger-sized second side 1311b, making the force more dispersed, which is beneficial to improving the supporting effect of the support member 13 on the radome 12 or the frequency selective surface 14.

[0070] In some other embodiments, please refer to FIG. 5B. FIG. 5B is a schematic cross-sectional structure diagram of another support member 13 provided by an embodiment of the present application. The first side 1311a can also be farther from the radome 12 or the frequency selective surface 14 of the antenna device 10 than the second side 1311b, and the embodiments of the present application do not limit this.

[0071] Please refer to FIG. 5C. FIG. 5C is a schematic cross-sectional structure diagram of another support member 13 provided by an embodiment of the present application. Exemplarily, the cross-section of the bearing part 131 can be approximately in the shape of a Chinese character 'ri' (日), and the bearing part 131 can further include a plate body 1311e, and the plate body 1311e is located in the space surrounded by the first side 1311a, the second side 1311b, the third side 1311c and the fourth side 1311d. At this time, the cross-section of the bearing part 131 is approximately in the shape of a Chinese character 'ri' (日), and the part where the plate body 1311e is located can be used to increase the structural strength of the bearing part 131.

[0072] For example, please refer to Figures 5D and 5E. Figure 5D is a schematic cross-sectional view of another support member 13 provided in an embodiment of this application. Figure 5E is a schematic cross-sectional view of another support member 13 provided in an embodiment of this application. The cross-section of the bearing portion 131 in Figure 5D can be approximately fan-shaped, and the cross-section of the bearing portion 131 in Figure 5E can be approximately circular. Both bearing portions 131 can have a large moment of inertia, enabling them to have good load-bearing performance, such as bending resistance and compression resistance. The sides of the bearing portion 131 can be straight lines or curves, etc., and this embodiment of the application does not limit this. In some embodiments, the length of the cross-section of the bearing portion 131 can be greater than or equal to 5 mm and less than or equal to 30 mm. Here, the cross-section of the bearing portion 131 refers to the cross-section of the area enclosed by the outer surface 13112 of the bearing portion 131. Exemplarily, the length of the cross-section of the bearing portion 131 can be 10 mm, 15 mm, 20 mm, or 25 mm, etc. By setting the length of the cross-section of the support portion 131 to be greater than or equal to 5 mm and less than or equal to 30 mm, it is possible to avoid the poor load-bearing capacity caused by an excessively small length of the support portion 131, and to avoid the excessive length of the support portion 131, which would occupy too much internal space within the antenna device 10 and increase manufacturing costs. In some other embodiments, the length of the cross-section of the support wall 1311 may also be less than 5 mm or greater than 30 mm, and this application embodiment does not limit this.

[0073] In some embodiments, the width of the cross-section of the support portion 131 can be greater than or equal to 5 mm and less than or equal to 30 mm. Here, the cross-section of the support portion 131 refers to the cross-section of the area enclosed by the outer surface 13112 of the support portion 131. Exemplarily, the width of the cross-section of the support portion 131 can be 10 mm, 15 mm, 20 mm, or 25 mm, etc. By setting the width of the cross-section of the support portion 131 to be greater than or equal to 5 mm and less than or equal to 30 mm, it is possible to avoid the poor load-bearing capacity caused by the width of the support portion 131 being too small, and to avoid the support portion 131 being too large, occupying too much internal space in the antenna device 10 and increasing manufacturing costs. In some other embodiments, the width of the cross-section of the support wall 1311 can also be less than 5 mm or greater than 30 mm, and this application embodiment does not limit this.

[0074] Understandably, when the cross-section of the support portion 131 is square, the length of the cross-section refers to the side lengths of the first side 1311a and the second side 1311b, and the width of the cross-section refers to the side lengths of the third side 1311c and the fourth side 1311d. When the cross-section of the support portion 131 is any shape other than square, the length of the cross-section refers to the dimension of the cross-section in the first direction, and the width of the cross-section refers to the dimension of the cross-section in the second direction. The first direction is parallel to the plane where the reflector 11 is located, and the second direction is perpendicular to the first direction.

[0075] Referring to FIG5A, in some embodiments, the support portion 131 may include a first cross section 13115 and a second cross section 13116, wherein the first cross section 13115 and the second cross section 13116 are different cross sections, and the first cross section 13115 and the second cross section 13116 may be arranged along the extending direction of the support portion 131.

[0076] In some embodiments, the areas of any two cross-sections of the support portion 131 can be equal. Here, the cross-section of the support portion 131 refers to the cross-section of the area enclosed by the outer surface 13112 of the support portion 131. The first cross-section 13115 and the second cross-section 13116 can be two cross-sections at any position. The areas of the first cross-section 13115 and the second cross-section 13116 can be equal. By setting the areas of any two cross-sections of the support portion 131 to be equal, the structure of the support portion 131 is simplified, which helps to reduce the manufacturing difficulty of the support portion 131 and simplify the manufacturing process to reduce manufacturing costs. In addition, the equal areas of any two cross-sections of the support portion 131 result in good dimensional uniformity and a good visual effect for the support portion 131.

[0077] In some other embodiments, the cross-sectional areas of the support portion 131 at different locations may be unequal. For example, the area of ​​the first cross-section 13115 and the area of ​​the second cross-section 13116 may be unequal. It is understood that the cross-sectional area of ​​the support portion 131 can be adaptively adjusted according to the different stress conditions in different regions of the support portion 131 to improve the design flexibility of the support portion 131.

[0078] Referring to Figures 4 and 5A, the supporting part 131 may include a first segment 1313, a second segment 1314, and a third segment 1315 arranged sequentially. The cross-sectional areas of the first segment 1313, the second segment 1314, and the third segment 1315 may be equal. Alternatively, the cross-sectional area of ​​the first segment 1313 may be smaller than that of the second segment 1314, and the cross-sectional area of ​​the third segment 1315 may be smaller than that of the second segment 1314. Having a larger cross-sectional area for the second segment 1314 improves the reliability of the supporting part 131 structure. The first cross-section 13115 may be located in the second segment 1314, and the second cross-section 13116 may be located in either the first segment 1313 or the third segment 1315. The areas of the first cross-section 13115 and the second cross-section 13116 may not be equal. The cross-sectional areas of the first segment 1313 and the third segment 1315 may be equal or unequal; this embodiment does not limit this.

[0079] In other embodiments, the area of ​​the cross-section from one end of the support portion 131 to the other end can be gradually increased and then gradually decreased, and the specific area can be set as needed.

[0080] In some embodiments, the support portion 131 can be a one-piece molded structure, which can have good structural strength and a simple manufacturing process. The material of the support portion 131 can be thermoplastic plastic or metal, and this application does not limit the material of the support member 13. The support portion 131 can be made of thermoplastic materials such as acrylonitrile-butadiene-styrene plastic, polycarbonate, polypropylene, or polyethylene, or metal materials such as aluminum, iron, or copper. The support portion 131 softens or flows when heated and hardens after cooling, making it easy to process and shape. In other embodiments, the support portion 131 can also be assembled from a first segment 1313, a second segment 1314, and a third segment 1315 to form a one-piece structure. The first segment 1313, the second segment 1314, and the third segment 1315 can be a one-piece molded structure or a separate structure, and this application does not limit this.

[0081] Please refer to Figures 5A and 6 in conjunction with Figure 6, which is an exploded view of the structure of the support member 13 shown in Figure 4 in some embodiments.

[0082] A portion of the first connecting portion 132 may be embedded in the support portion 131, or a portion of the second connecting portion 133 may be embedded in the support portion 131, or a portion of the first connecting portion 132 may be embedded in the support portion 131 and a portion of the second connecting portion 133 may be embedded in the support portion 131. In this embodiment, taking the embedding of a portion of the first connecting portion 132 in the support portion 131 and a portion of the second connecting portion 133 in the support portion 131 as an example, the connection reliability and strength between the first connecting portion 132, the second connecting portion 133, and the support portion 131 can be improved. In other embodiments, please refer again to FIG5B, a portion of the first connecting portion and / or a portion of the second connecting portion 133 may also surround the outer periphery of a portion of the support portion 131, which can also improve the connection reliability between the first connecting portion and the second connecting portion 133 and the support portion 131. This will not be elaborated further in this embodiment.

[0083] The first connecting portion 132 may include an embedding structure 1321, which is the portion of the first connecting portion 132 embedded within the supporting portion 131. The embedding structure 1321 may include a main body portion 13211 and an elastic body 13212 fixed to the main body portion 13211. The supporting wall 1311 may be provided with a mounting hole 13113, the main body portion 13211 may be embedded within the supporting portion 131, and the elastic body 13212 may be embedded within the mounting hole 13113. By providing the elastic body 13212 embedded within the mounting hole 13113, a detachable connection between the first connecting portion 132 and the supporting portion 131 can be achieved, which is beneficial to improving the reliability of the connection between the first connecting portion 132 and the supporting portion 131. When the first connecting part 132 is installed onto the support part 131, the main body part 13211 extends into the support part 131, and the elastic body 13212 elastically embeds into the mounting hole 13113. When the first connecting part 132 is separated from the support part 131, the elastic body 13212 pops out of the mounting hole 13113, and the main body part 13211 moves out of the support part 131.

[0084] The elastic body 13212 may include an elastic buckle 1321a and a retaining post 1321b. The retaining post 1321b may be fixed to one end of the elastic buckle 1321a, and the other end of the elastic buckle 1321a may be fixed to the main body 13211. During the process of the first connecting part 132 being inserted into the bearing part 131, the elastic buckle 1321a may undergo elastic deformation. When the first connecting part 132 is installed in the preset position, the retaining post 1321b is tightly connected to the mounting hole 13113 under the action of the rebound force of the elastic buckle 1321a.

[0085] The locking post 1321b may include a guide surface 1321c (as shown in Figure 4). The guide surface 1321c can play a guiding role when the embedded structure 1321 is embedded in the support part 131, so as to facilitate the installation of the first connecting part 132 and the support part 131.

[0086] Referring to Figure 6, the first connecting part 132 may include a snap-fit ​​structure 1322, which is used to snap the reflector 11 (as shown in Figure 3) to achieve a fixed connection between the first connecting part 132 and the reflector 11.

[0087] For example, the snap-fit ​​structure 1322 may include a positioning protrusion 13221 and two elastic clips 13222 located on both sides of the positioning protrusion 13221. The two elastic clips 13222 are capable of elastic deformation and passing through the slots (not shown in the figure) provided on the reflector 11, and after the elastic deformation recovers, they are snapped onto the reflector 11, so that the elastic clips 13222 will not fall out of the slots. The positioning protrusion 13221 is located in the positioning opening (not shown in the figure) provided on the reflector 11, realizing the positioning of the first connecting part 132 and the reflector 11.

[0088] The first connecting portion 132 may further include an abutment structure 1323, which is located outside the supporting portion 131 and between the snap-fit ​​structure 1322 and the embedded structure 1321. In some examples, the abutment structure 1323 may include an abutment surface 13231, which abuts against the supporting portion 131, with the projection of the supporting portion 131 onto the abutment surface 13231 covering the portion of the abutment surface 13231. By providing an abutment surface 13231 covering the projection of the supporting portion 131 onto the abutment surface 13231—in other words, with the size of the abutment surface 13231 larger than the size of the end face of the supporting portion 131—it is beneficial to improve the support of the abutment structure 1323 for the supporting portion 131 and to improve the connection reliability between the first connecting portion 132 and the supporting portion 131. The abutment structure 1323 may be a hollow structure, which is beneficial to reduce material usage, lower production costs, and achieve weight reduction. In some other embodiments, the size of the abutment surface 13231 may be less than or equal to the size of the end face of the bearing portion 131, and this application embodiment does not limit this.

[0089] In this embodiment, taking the connection between the first connecting part 132 and the supporting part 131 as an example, the structure of the second connecting part 133 and the connection relationship between the second connecting part 133 and the supporting part 131 can be referenced to the structure of the first connecting part 132 and the connection relationship between the first connecting part 132 and the supporting part 131. This embodiment will not elaborate further. In other embodiments, the structure of the second connecting part 133 and the connection relationship between the second connecting part 133 and the supporting part 131 may differ from the design of the first connecting part 132. This embodiment will not limit this aspect.

[0090] Referring to the embodiment shown in Figure 2, please refer to Figures 7A and 7B. Figure 7A is a structural schematic diagram of another antenna device 10 provided in this application embodiment. Figure 7B is a structural schematic diagram of the antenna device 10 shown in Figure 7A from another perspective. The shape of the first part 121 can be arc-shaped, and the shape of the support member 13 can also be arc-shaped to provide better support.

[0091] Please refer to Figures 8A and 8B. Figure 8A is a structural schematic diagram of another support member 13 provided in an embodiment of this application. Figure 8B is an exploded structural schematic diagram of the support member 13 shown in Figure 8A in some embodiments. The support member 13 is arc-shaped. The bearing portion 131 may include a first sub-bearing portion 1316 and a second sub-bearing portion 1317. The support member 13 may also include a third connecting portion 134, which connects the first sub-bearing portion 1316 and the second sub-bearing portion 1317. By providing the third connecting portion 134, the third connecting portion 134 can support the bearing portion 131, which helps to improve the reliability of the support member 13.

[0092] The third connecting part 134 may include a first connecting segment 1341, a second connecting segment 1342, and a third connecting segment 1343. The first connecting segment 1341 is connected between the first sub-supporting part 1316 and the second sub-supporting part 1317. The third connecting segment 1343 is fixedly connected to the reflector 11. The second connecting segment 1342 is fixedly connected between the first connecting segment 1341 and the third connecting segment 1343. The third connecting part 134 is an integral structure formed by assembling the first connecting segment 1341, the second connecting segment 1342, and the third connecting segment 1343. This reduces the difficulty of manufacturing, handling, and installing the third connecting part 134, thereby reducing the manufacturing cost of the support member 13. The third connecting segment 1343 can be connected to the reflector 11 by means of snap-fit, screws, sleeves, or adhesive. In this embodiment, the structure of the third connecting segment 1343 can refer to the structure of the first connecting portion 132, and the connection method between the third connecting segment 1343 and the reflector 11 can also refer to the connection relationship between the first connecting portion 132 and the reflector 11. In other embodiments, the structure of the third connecting segment 1343 may be different from that of the first connecting portion 132, and this application does not limit this. The third connecting portion 134 can also be an integrally formed structure.

[0093] Please refer to Figures 9 to 11. Figure 9 is a structural schematic diagram of another antenna device 10 provided in an embodiment of this application. Figure 10 is a partial structural schematic diagram of the antenna device 10 shown in Figure 9. Figure 11 is a structural schematic diagram of the fixing member 15 shown in Figure 10.

[0094] The antenna device 10 may include a frequency selective surface 14, and a support member 13 may be used to support the frequency selective surface 14, such that the frequency selective surface 14 and the reflector 11 are kept at a distance to meet different electrical requirements. The frequency selective surface 14 has a specific frequency selection function, exhibiting transmissivity for incident waves in one frequency band and reflectivity for incident waves in another frequency band, thereby effectively controlling the transmission and reflection of incident electromagnetic waves. For example, the frequency selective surface 14 may be a device such as a space filter, which can interact with electromagnetic waves and exhibit obvious band-pass or band-stop filtering characteristics.

[0095] In some embodiments, the antenna device 10 may further include a fixing member 15. The fixing member 15 may include a carrier plate 151 and fixing buckles 152 disposed at both ends of the carrier plate 151. The frequency selective surface 14 may be provided with fixing holes (not shown in the figure). Part of the fixing buckles 152 may pass through the fixing holes of the frequency selective surface 14 and be engaged with the frequency selective surface 14 to fix the frequency selective surface 14 to the support member 13. For example, the fixing member 15 may be a plastic part formed by injection molding. The fixing member 15 can be used to realize the fixed connection between the support member 13 and the frequency selective surface 14, which is beneficial to improve the connection reliability between the support member 13 and the frequency selective surface 14.
