Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an antenna radome, an antenna, and a communication device. Background Technology

[0002] As a crucial component of an antenna, the radome typically covers the radiating element and protects it. Electrically, the radome possesses excellent electromagnetic wave penetration characteristics; mechanically, it can withstand harsh external environments, thus protecting the radiating element from environmental influences. However, since the radome is exposed to the outdoors for extended periods, poor reliability can lead to breakage and damage, exposing the internal radiating element to the external environment and causing it to malfunction. Therefore, improving the reliability of the radome is a pressing issue in this field. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0020] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 2 This application discloses an radome, which includes a radome body 110 and a cover plate 120. The radome body 110 can be a hollow structure in the shape of a cylinder or prism. Figure 1 A quadrangular prism-shaped enclosure 110 is shown. The enclosure 110 can be composed of two parts: a first part for connecting a cover plate 120, and a second part that can be connected below the first part to form an extended space to increase the coverage area of ​​the enclosure 110. The enclosure 110 has an opening, which is actually opened in the first part of the enclosure 110 described above. The cover plate 120 is disposed at the opening of the enclosure 110, and the cover plate 120 and the enclosure 110 form a receiving cavity 130, which can be used to accommodate a radiating element. The radiating element is a unit that constitutes the basic structure of the antenna and can effectively radiate or receive radio waves.

[0022] like Figure 2 As shown, the cover plate 120 and the radome 110 can be assembled in the following manner: the cover plate 120 has a first surface 121, a second surface 122, and an end face 123. The first surface 121 of the cover plate 120 faces the receiving cavity 130, and the second surface 122 of the cover plate 120 faces away from the first surface 121. The first surface 121 and the second surface 122 are connected through the aforementioned end face 123. The end face 123 of the cover plate 120 can be embedded into the radome 110. Correspondingly, the radome 110 can be connected to the end face 123, a portion of the first surface 121, and a portion of the second surface 122 of the cover plate 120, respectively. The specific connection methods can be heat fusion, bonding, snap-fit, etc. Since a portion of the cover plate 120 is embedded into the radome 110, the connection strength between the cover plate 120 and the radome 110 is improved, thereby improving the reliability of the radome.

[0023] In one embodiment, the cover plate 120 and the radome 110 can be made of different materials. Considering that radomes are mostly used outdoors, they are subject to thermal expansion and contraction due to changes in outdoor temperature. Since different materials have different coefficients of thermal expansion, temperature changes will cause them to expand or contract at different rates. This will result in relative movement between them, thereby generating stress at the contact interface. Continuous thermal cycling will lead to the accumulation of stress. When the stress exceeds the strength limit of the material, cracking will occur, further affecting its performance.

[0024] Based on the above-mentioned problems, in another embodiment of this application, the material of the cover plate 120 and the material of the cover body 110 can be the same. When the outdoor temperature changes, the cover plate 120 and the cover body 110 will expand or contract at the same rate, thereby reducing the probability of relative movement between the two and making it less likely for stress to be generated at the contact interface between the cover plate 120 and the cover body 110, thus reducing the probability of cracking of the cover plate 120 and the cover body 110. The material selection of the cover plate 120 and the cover body 110 needs to take into account factors such as dielectric properties, mechanical strength, weather resistance, and weight. Specifically, polypropylene, polyethylene, polystyrene, polycarbonate, polyamide, etc. can be selected.

[0025] As described above, the radome disclosed in this application improves upon related technologies. Since the cover plate 120 is assembled into the radome 110 by embedding, the reliability of the radome is improved to a certain extent. Furthermore, the material of the cover plate 120 is the same as that of the radome 110, so the cover plate 120 and the radome 110 have the same coefficient of thermal expansion. Therefore, when the external temperature changes, the expansion and contraction of the cover plate 120 and the radome 110 are consistent, thereby reducing the risk of deformation and cracking caused by thermal stress and further improving the reliability of the radome.

[0026] As described above, the cover plate 120 is assembled to the cover body 110 by an embedded installation method. The connection method between the cover plate 120 and the cover body 110 can be heat fusion or adhesive bonding. Specifically, heat fusion is a method of joining materials together by heating them to their melting point. For example, at least one of the areas of the cover plate 120 that are connected to the cover body 110 and the areas of the cover body 110 that are connected to the cover plate 120 can be heated to melt using a heating tool. Then, the cover plate 120 and the cover body 110 are assembled together, so that the cover body 110 is tightly fitted to the end face 123, part of the first surface 121, and part of the second surface 122 of the cover plate 120, and held under pressure for a period of time until it cools and solidifies. Alternatively, at least one of the areas of the cover plate 120 for connection with the cover body 110 and the areas of the cover body 110 for connection with the cover plate 120 can be coated with an adhesive such as epoxy glue or acrylic glue, and then the cover plate 120 and the cover body 110 can be assembled together. The two can be bonded together after the adhesive cures.

[0027] In one optional embodiment of this application, the cover plate 120 can be heat-fused to the cover body 110 by injection molding. Specifically, a mold can be set on the cover body 110, and the material required to make the cover plate 120 can be heated to melt and poured into the mold. After the cover plate 120 solidifies, the mold can be removed. The use of injection molding for the cover plate 120 can improve the fit between the end face 123, part of the first surface 121, and part of the second surface 122 of the cover body 110 and the cover plate 120, further improving the reliability of the assembly of the cover body 110 and the cover plate 120.

[0028] The cover 110 can be formed by hot pressing or by injection molding. In an optional embodiment of this application, both the cover 110 and the cover plate 120 can be manufactured by injection molding to achieve a heat-fusion connection between them. Specifically, the cover 110 and the cover plate 120 can be manufactured using the same mold, which includes a first cavity and a second cavity. The cover 110 can be injection molded through the first cavity of the mold, and the cover plate 120 can be injection molded through the second cavity of the mold. Regarding the order of injection molding of the cover 110 and the cover plate 120, the cover 110 can be manufactured first, and after the cover 110 has solidified, the cover plate 120 can be manufactured; or, the cover plate 120 can be manufactured first, and after the cover plate 120 has solidified, the cover 110 can be manufactured. Using injection molding for both the cover 110 and the cover plate 120 can further improve the fit between the end face 123, part of the first surface 121, and part of the second surface 122 of the cover 110 and the cover plate 120.

[0029] Because the cover plate 120 needs to have good wave transmittance to ensure that the radiating unit can radiate or receive radio waves normally, the thickness of the cover plate 120 cannot be too large. The enclosure 110 needs to provide sufficient support for the cover plate 120, therefore the enclosure 110 needs to have a certain structural strength. Based on the above usage requirements, the direction perpendicular to the line connecting the first surface 121 and the second surface 122 of the cover plate 120 is defined as the first direction 140. Then, along the first direction 140, the projections of the cover plate 120 and the enclosure 110 overlap. In this overlapping area, the thickness of the enclosure 110 in the first direction 140 is greater than the thickness of the cover plate 120 in the first direction 140. This differentiated thickness design ensures that the enclosure 110 has sufficient structural strength to support the cover plate 120 and provides stable protection for the internal radiating unit, enabling the cover plate 120 to meet the requirements for the radiating unit to radiate or receive radio waves normally.

[0030] For the cover plate 120 described above to be assembled into the cover body 110 by embedding, a mounting groove 111 can be provided on the side of the cover body 110 near the receiving cavity 130. The mounting groove 111 has a first sidewall, a second sidewall, and a bottom wall. The first sidewall and the second sidewall are arranged opposite to each other and connected through the bottom wall. The opening of the mounting groove 111 is arranged opposite to the bottom wall. The end face 123 of the cover plate 120 can be embedded into the mounting groove 111 through the opening of the mounting groove 111. The end face 123 of the cover plate 120 is connected to the bottom wall. The first sidewall of the mounting groove 111 is connected to a portion of the first surface 121 of the cover plate 120, and the second sidewall of the mounting groove 111 is connected to a portion of the second surface 122 of the cover plate 120. Since there is an overlapping area between the edges of the mounting groove 111 and the cover plate 120, the cover plate 120 can be prevented from falling out of the mounting groove 111, thus improving the stability of the assembly of the cover plate 120 and the cover body 110.

[0031] To further prevent the cover plate 120 from coming out of the mounting groove 111, a first limiting structure can be provided in the mounting groove 111 and a second limiting structure can be provided on the cover plate 120. When the end face 123 of the cover plate 120 is embedded in the mounting groove 111, the first limiting structure and the second limiting structure cooperate to limit the fit, so that the cover plate 120 can be firmly embedded in the mounting groove 111.

[0032] For example, the first limiting structure described above can be a column, with its two ends connected to the first and second sidewalls of the mounting groove 111, respectively. The second limiting structure can be a through hole formed at the edge of the cover plate 120, connecting the first surface 121 and the second surface 122 of the cover plate 120. In actual assembly, the cover body 110 can be fabricated first, and then the cover plate 120 can be heat-fused to the cover body 110 by injection molding. During the forming process of the cover plate 120, due to the presence of the column, the cover plate 120 will avoid the column and form the aforementioned through hole. After the cover plate 120 has solidified, the column and the through hole can mutually limit each other, thereby preventing the cover plate 120 from coming out of the mounting groove 111. Alternatively, the first limiting structure described above can also be a boss, and correspondingly, the second limiting structure can be a groove. A boss may be formed on the first sidewall of the mounting groove 111, and a groove may be formed on the first surface 121 of the cover plate 120. When the cover plate 120 is embedded in the mounting groove 111, the boss and the groove are mutually restrained; and / or, a boss may be formed on the second sidewall of the mounting groove 111, and a groove may be formed on the second surface 122 of the cover plate 120. When the cover plate 120 is embedded in the mounting groove 111, the boss and the groove are mutually restrained.

[0033] This application also discloses an antenna, which includes a radiating element and the aforementioned radome. The radiating element is located in the receiving cavity 130 of the radome. The radome can protect the radiating element and prevent it from being affected by the external environment. Furthermore, the radome has good electromagnetic wave penetration characteristics in terms of electrical performance, thereby ensuring that the antenna can work normally while having good stability and reliability.

[0034] It should be understood that since the principle by which this antenna solves the problem is similar to that of the aforementioned radome, the implementation and technical effects of this antenna can be found in the implementation and technical effects of the aforementioned radome, and the repetition will not be repeated.

[0035] This application also discloses a communication device, which may include the antenna described above. Of course, in addition to the antenna, the communication device may also include other devices or apparatuses such as terminals; the specific design can be tailored to actual needs, and this application does not impose any limitations here. The antenna enables signal transmission and reception with the terminal, thus achieving communication; given the antenna's good stability and reliability, the communication device can also possess good stability and reliability.

[0036] It should be understood that since the principle by which this communication device solves the problem is similar to that of the aforementioned antenna, the implementation and technical effects of this communication device can be found in the implementation and technical effects of the aforementioned antenna, and the repetition will not be repeated.

[0037] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. For the sake of brevity, they will not be described in detail here.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
