[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0047] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0048] See also Figures 1-9 As shown, a support member 1 for an antenna radiation unit, whose unique design provides a strong guarantee for the stable operation and high efficiency performance of the antenna.

[0049] The support member primarily comprises a cross-shaped base plate 11. On the front faces of the four cantilevered arms of the base plate 11, carefully positioned first clamping members 12 of equal height are meticulously positioned. These first clamping members 12 are primarily used to engage the radiating surface 2. This tight engagement ensures the positional stability of the radiating surface 2 during operation, thereby guaranteeing stable signal radiation and reception.

[0050] Likewise, on the front faces of the four cantilevered arms of the base plate 11, second clipping assemblies 13 of equal height are provided for clipping onto the bandwidth loading plate 3. This design ensures that the bandwidth loading plate 3 can be accurately installed in the intended position, providing strong support for optimizing the antenna's bandwidth performance.

[0051] At the center of the base plate 11, a third snap-fit assembly 14 is provided for interference fit with the radiating plate 4. This interference fit ensures a tight connection between the radiating plate 4 and the support, minimizing possible loosening and displacement, thereby ensuring the stable performance of the radiating plate 4.

[0052] Around the front of the substrate 11, where the third snap-in assembly 14 is located, a fourth snap-in assembly 15 is provided for the director plate 5 to snap in. The rational layout and precise design of these snap-in assemblies enable the director plate 5 to effectively play its role in guiding signals, further improving the performance of the antenna.

[0053] It is worth noting that the first clamping member 12 is lower than the second clamping assembly 13, which in turn is lower than the fourth clamping assembly 15. This clever height design not only prevents the various components from interfering with each other during installation, but also optimizes the spatial layout within the antenna, improving the efficiency and stability of signal transmission.

[0054] On the back of the substrate 11, there is provided a fifth clamping assembly 16 that is clamped to the feed plate 6. Through this design, the feed plate 6 can be firmly mounted on the support, providing a stable power supply for the antenna.

[0055] What is particularly important is that the substrate 11, the first clip 12, the second clip assembly 13, the third clip assembly 14, the fourth clip assembly 15 and the fifth clip assembly 16 are integrally formed. This one-piece design brings many significant advantages. First, the modular design of the radiation unit can be achieved through the use of support parts. This means that the structure of the parts that affect the performance can be fine-tuned according to different performance requirements, so as to accurately meet specific performance requirements and achieve the intended purpose of use. Secondly, the one-piece design significantly reduces the number of molds. During the production process, there is no need to develop multiple molds for each individual component, which greatly reduces production costs and production cycles. Moreover, this design makes the assembly process simple and convenient, without the need for complex operations and tedious steps, saving a lot of manufacturing and assembly costs. Finally, the one-piece structure makes the performance of the support stable and firm, and can maintain good working condition under various complex environmental conditions, providing a solid foundation for the long-term and stable operation of the antenna.

[0056] Specifically, support member 1 is made of 30% glass fiber reinforced POM material. This 30% glass fiber reinforced POM material is a known prior art material and is commercially available. This material provides support member 1 with high strength and toughness, particularly outstanding tensile and flexural strength. This makes support member 1 less susceptible to deformation or breakage when subjected to tensile forces, effectively ensuring the positional accuracy and stability of connected components.

[0057] Specifically, if Figure 6 As shown, the upper end of the first clamping member 12 has an elastic first bending portion 121, which can provide a certain buffering and adaptability when clamping with the radiating surface 2, making the clamping process smoother, and at the same time effectively reducing the damage that may be caused to the radiating surface 2 due to hard collision.

[0058] The first clamping member 12, located below the first bend 121, also features a first step 122 for the radiating surface 2 to rest on. This first step 122 provides a clear and stable placement for the radiating surface 2. When placed on the first step 122, the radiating surface 2 is precisely positioned, ensuring it is in the correct operating position, thereby ensuring stable antenna performance. Furthermore, the interaction between the first bend 121 and the first step 122 effectively secures the radiating surface 2 during the clamping process, preventing it from shifting or loosening, thereby enhancing the stability and reliability of the entire structure.

[0059] Specifically, the second clamping assembly 13 is composed of at least three second clamping members 131 of equal height (in this embodiment, each second clamping assembly 13 is composed of three second clamping members 131). This combination enhances the clamping stability and reliability of the bandwidth loading piece 3.

[0060] Further, if Figure 7 As shown, the upper end of each second clamping member 131 has an elastic second bent portion 1311. When clamping with the wide loading plate 3, the second bent portion 1311 can play a buffering role, making the clamping action softer and avoiding possible hard impact damage to the wide loading plate 3.

[0061] Located below the second bend 1311, the second clamping member 131 features a second step 1312 for placing the bandwidth loading sheet 3. This provides a clear, horizontal placement area for the bandwidth loading sheet 3. When placed on the second step 1312, the bandwidth loading sheet 3 is precisely positioned, ensuring it is in the intended operating position, thereby optimizing the antenna's bandwidth performance. Furthermore, the second bend 1311 and the second step 1312 work together to more securely secure the bandwidth loading sheet 3 during the clamping process, preventing it from shifting or loosening during operation, significantly enhancing the stability and performance of the entire antenna structure.

[0062] Specifically, the fourth clamping assembly 15 is composed of at least three fourth clamping parts 151 of equal height (in this embodiment, each fourth clamping assembly 15 is composed of four fourth clamping parts 151). Such quantity and arrangement effectively improve the stability and balance of the clamping of the guide plate 5.

[0063] like Figure 8As shown, the upper end of each fourth engaging member 151 is equipped with a resilient fourth bent portion 1511. This provides a good buffering effect when engaging with the guide plate 5, making the engagement process smoother and preventing damage to the guide plate 5 caused by sudden, forceful contact. Furthermore, its elastic nature imparts a certain degree of adaptability, allowing it to flexibly accommodate subtle variations in the size or installation position of the guide plate 5, thereby increasing the adaptability and fault tolerance of the engagement.

[0064] A fourth step 1512 is provided on the fourth clamping member 151, located below the fourth bend 1511, for placing the guide plate 5. This provides a precise and stable placement for the guide plate 5. When the guide plate 5 is placed on the fourth step 1512, it can be precisely positioned, ensuring that the guide plate 5 is in the correct working position, thereby fully exerting its role in guiding signals and improving the overall performance of the antenna. Furthermore, the fourth bend 1511 and the fourth step 1512 cooperate with each other to firmly secure the guide plate 5 during the clamping process, effectively preventing it from shifting or loosening during operation. This greatly enhances the stability and reliability of the antenna structure and provides a strong guarantee for the efficient and stable operation of the antenna.

[0065] Specifically, the third clamping assembly 14 is composed of four third clamping members 141 . The four third clamping members 141 are arranged in a horizontal distribution and form a cross-shaped clamping groove 142 between each other.

[0066] The aforementioned slot 142 is adapted to the radiating plate 4. The interference fit between the slot 142 and the radiating plate 4 greatly improves the stability and reliability of the placement of the radiating plate 4. This interference fit ensures a tight fit between the radiating plate 4 and the slot 142, effectively reducing the possibility of loosening or displacement during operation, thereby ensuring that the radiating plate 4 always maintains its accurate position and guarantees the antenna's signal radiation and reception performance.

[0067] Furthermore, the third engaging member on one side of the slot 142 has a resilient third bent portion 1411. This provides a certain degree of elastic cushioning during installation of the radiating plate 4, making the installation process smoother and reducing potential damage to the radiating plate 4. Furthermore, after installation, the elastic restoring force of the third bent portion 1411 further enhances the tightness of the engagement between the slot 142 and the radiating plate 4, further improving the secure placement of the radiating plate 4.

[0068] Specifically, the fifth clamping assembly 16 is composed of at least three fifth clamping parts 161 of equal height (in this embodiment, the fifth clamping assembly 16 is composed of four fifth clamping parts 161). This number and layout effectively ensure the stability and balance of the clamping of the feed plate 6.

[0069] like Figure 9As shown, one end of each fifth clamping member 161 is provided with an elastic fifth bending portion 1611. The fifth bending portion 1611 has a guiding slope from bottom to top, which guides the clamping operation of the feed plate 6, thereby making the clamping process smoother and more stable, greatly reducing the risk of damage to the feed plate 6.

[0070] The upper end surface of the fifth bend 1611 is a fifth step 1612 for placing the feed plate 6. It provides a precise and stable placement position for the feed plate 6. When the feed plate 6 is placed on the fifth step 1612, it can achieve precise positioning, ensuring that the feed plate 6 is in the correct working position, thereby providing strong support for the stable power supply of the antenna. In addition, the fifth bend 1611 and the fifth step 1612 cooperate with each other to tightly fix the feed plate 6 during the clamping process, effectively preventing it from being displaced or loosened during operation, greatly improving the stability and reliability of the antenna structure, and providing a solid guarantee for the efficient and stable operation of the antenna.

[0071] Combine Figure 10 、 Figure 11 As shown, a radiation unit includes a support member 1 with the above-mentioned structure. In this structure, the radiation surface 2 is clamped onto the first clamping member 12 of the support member 1. The radiation surface 2 is specially provided with a slot 21 for the second clamping component 13 and the fourth clamping component 15 to extend out. This design provides space for the installation and movement of related components. On the radiation surface 2 outside the slot 21, a first clamping groove 22 is also provided, which is precisely clamped to the first clamping member 12. Through this clamping method, the radiation surface 2 can be firmly combined with the support member 1, providing a basis for the radiation and reception of signals.

[0072] The second snap-fit assembly 13 of the support member 1 snaps onto the bandwidth loading piece 3. To ensure a secure snap-fit, the bandwidth loading piece 3 is provided with a second snap-fit groove 31 that mates closely with the second snap-fit element 131. This design of the snap-fit groove and snap-fit element ensures the stable position of the bandwidth loading piece 3 during operation, effectively optimizing the bandwidth performance of the antenna.

[0073] The fourth engaging assembly 15 of the support member 1 is provided with a guide plate 5. Similarly, the guide plate 5 is provided with a third engaging slot 51 that precisely engages with the fourth engaging member 151. This precise engagement structure enables the guide plate 5 to accurately perform its signal guiding function, further improving antenna performance and signal transmission efficiency.

[0074] The third clamping assembly 14 of the support member 1 is connected to the upper end of the radiating plate 4 using an interference fit. This tight interference fit greatly improves the stability and reliability of the placement of the radiating plate 4, effectively reduces the possibility of loosening or displacement during operation, and ensures that the radiating plate 4 can stably perform its function, thereby ensuring the signal radiation effect of the antenna.

[0075] In addition, the fifth clamping assembly 16 of the support member 1 is clamped with the protrusion 61 of the feed plate 6. This clamping method enables the feed plate 6 to be firmly mounted on the support member 1, providing a stable and continuous power supply for the antenna, ensuring the normal operation of the antenna system.

[0076] In summary, through the precise and stable snap-fit connection between each component and the support member 1 , the radiation unit achieves efficient and stable performance, providing strong support for the smooth operation of the communication system.
