Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a protective antenna. Background Art

[0002] With the rapid development of wireless communication technology, antennas are key components for signal reception and transmission, and their performance and stability are crucial for all kinds of electronic devices. However, in practical applications, antennas often face challenges from harsh environments such as water vapor and dust, especially in outdoor equipment, underwater equipment, and high humidity environments, where waterproof performance is indispensable.

[0003] Currently, traditional antenna waterproofing designs mainly adopt two strategies.

[0004] The first strategy is to add a waterproof pad between the outer shell and the lower cover and fix it by locking screws. Although this design improves the waterproof performance of the antenna to a certain extent, it has many shortcomings. First, it requires a large amount of materials such as waterproof pads and screws and labor for assembly, which increases production costs. Secondly, due to the presence of waterproof pads and screws, the overall structure of the antenna becomes complicated, which is easy to cause assembly errors and lead to unstable waterproof performance. In addition, this design often fails to meet the high-level waterproof standard of IP68.

[0005] The second strategy is to achieve waterproofing by filling the inside of the antenna with glue. Although this design simplifies the assembly process to a certain extent, its impact on antenna performance cannot be ignored. The glue will change the dielectric constant of the antenna, causing the antenna frequency to shift, thereby reducing the performance indicators of the antenna. In addition, after the glue is cured, it is easy to generate stress, causing damage to the antenna PCB board, further affecting the service life of the antenna.

[0006] Therefore, the present application proposes a protection antenna. Utility Model Content

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0037] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0038] IP68 is the highest level of waterproof rating for connectors. IP (Ingress Protection) is a protection rating system drafted by IEC (International Electrotechnical Commission) to classify electrical appliances according to their dust and moisture resistance characteristics. The "6" and "8" in IP68 represent two different protection levels:

[0039] "6" means completely preventing the intrusion of foreign objects and dust, that is, completely dustproof.

[0040] "8" means that the appliance can be submerged indefinitely at the specified water pressure to ensure that there is no damage due to immersion, that is, continuous immersion.

[0041] Antennas that meet IP68 protection are not only completely dustproof, but can also withstand continuous immersion in water for a long time under a certain water pressure without being damaged. They are suitable for wireless communication equipment working under extreme environmental conditions, such as deep-sea exploration equipment and communication equipment in outdoor extreme climate areas.

[0042] It should be noted that although IP68 is the highest level of protection, it does not mean that the device can be completely waterproof in all circumstances. For example, for some devices, if their interfaces or gaps are not properly sealed, they may be damaged due to water infiltration even if they reach the IP68 level. Therefore, when designing and using devices that meet the IP68 protection level, it is still necessary to handle them with caution and ensure that all interfaces and gaps are properly sealed. Therefore, this utility model details a protective antenna with an IP68 protection level.

[0043] The protective antenna of the utility model comprises an upper cover 1, an antenna assembly 2, a lower cover 3, a first glue layer 51 and a cable 4. Figure 1 Furthermore, the protective antenna may further include a second glue layer (not shown in the figure). In some preferred embodiments, the protective antenna may further include a third glue layer (not shown in the figure).

[0044] The upper cover 1 of the utility model includes a top plate and a side plate, one side of the side plate is connected to the top plate to form a hollow structure with one end open, which provides an installation environment for the antenna assembly 2. Figure 4 , the upper cover 1 is similar to a barrel-shaped structure. When in use, a mounting ear 11 is provided on the outer wall of the upper cover 1, and a connecting piece 111 is provided on the mounting ear 11. The connecting piece 111 is used to install the protective antenna on the external structure. In actual application, two mounting ears 11 are symmetrically provided on the outer wall of the side plate of the upper cover 1, and each mounting ear 11 is provided with a hole to facilitate the passage of bolts or other connecting pieces 111, so that the upper cover 1 can be stably and reliably installed in the desired position. Such a design not only facilitates the installation and disassembly of the upper cover 1, but also ensures the reliability and safety of the connection. In some preferred embodiments, the shape, size and number of the mounting ears 11 can be adjusted according to the installation environment. For example, if the upper cover 1 needs to withstand greater external force or vibration, the mounting ears 11 can be set to be thicker to increase the stability of the connection.

[0045] The inner wall of the upper cover 1 of the present invention is provided with a second rib 12, referring to Figure 4 . Furthermore, a third rib position 13 may be provided on the inner wall of the upper cover 1. When applied, a plurality of second rib positions 12 may be provided, each of which is a cylindrical structure, and a fastener 121 is provided at one end of the second rib position 12. The second rib position 12 is installed on the inner wall of the upper cover 1 through a support member, and the connection range of the second rib position 12 can be expanded during the assembly process. In actual application, a plurality of third rib positions 13 may be provided, and the third rib position 13 is a sheet structure, and a limiting fixing structure 131 is provided on the third rib position 13. The limiting fixing structure 131 is formed by removing one side of one end of the third rib position 13 to form a limiting fixing structure 131 having a limiting step and a fixing plate. In some preferred embodiments, the second rib position 12 and the third rib position 13 intersect on the top plate of the upper cover 1.

[0046] The beneficial effect of the above scheme is that the second rib position 12 and the third rib position 13 arranged at the intersection of the top plate of the upper cover 1 can effectively disperse and resist the pressure and impact from the outside, thereby preventing the upper cover 1 from being deformed or damaged, thereby significantly enhancing the structural stability and overall rigidity of the upper cover 1. Especially in harsh environments, the upper cover 1 of the present application can ensure the stability and reliability of the protective antenna and ensure the normal transmission of signals.

[0047] Furthermore, a fastener 121 is provided on the second rib position 12, and a position-limiting fixing structure 131 is provided on the third rib position 13, which can play a guiding and positioning role during the production and assembly process. Specifically, during the assembly process, the second rib position 12 and the third rib position 13 can help quickly and accurately locate the components of the protective antenna, reduce the difficulty and error rate of assembly, and not only improve production efficiency, but also reduce quality problems caused by improper assembly.

[0048] The antenna assembly 2 of the present invention includes an antenna radiation unit 22 and an antenna grounding unit 21. Figure 1 Furthermore, the antenna assembly 2 may also include a GPS unit 23 .

[0049] The antenna grounding unit 21 of the utility model has a first side and a second side that are relatively arranged. The antenna grounding unit 21 can be a PCB board, on which a grounding layer of the antenna is formed. The first side of the antenna grounding unit 21 is connected to the antenna radiation unit 22 and the GPS unit 23, so as to realize effective transmission and grounding of the signal. The periphery of the antenna grounding unit 21 is connected to the inner wall of the opening of the upper cover 1. When used, the periphery of the antenna grounding unit 21 is provided with a third glue layer for fixing the periphery of the antenna grounding unit 21 to the inner wall of the upper cover 1. In actual application, refer to Figure 1 The antenna grounding unit 21 is provided with a first notch 201, which may be a through hole, and the first notch 201 is used to penetrate the second rib 12. Specifically, refer to Figure 3 , after the second rib position 12 is inserted from one side of the first notch 201, the fastener 121 is installed on the second rib position 12 from the other side of the first notch 201, so that the antenna grounding unit 21 is fixedly connected to the second rib position 12. Furthermore, a second notch 202 may be provided on the antenna grounding unit 21. The second notch 202 is used to accommodate the fixing plate of the third rib position 13. Specifically, the fixing plate of the limiting fixing structure 131 of the third rib position 13 is inserted into the second notch 202, and the limiting step of the limiting fixing structure 131 is abutted against the first side of the antenna grounding unit 21. The second notch 202 cooperates with the third rib position 13, and the antenna grounding unit 21 can be pre-fixed during assembly. In some preferred embodiments, a mounting hole is opened on the antenna grounding unit 21, and a wire plug 211 is provided on the mounting hole. The wire plug 211 is used for sealing and passing the cable 4. When glue is poured on the second side of the antenna grounding unit 21, the wire plug 211 can prevent the glue from flowing through the mounting hole to the first side of the antenna grounding unit 21, thereby avoiding affecting the performance of the antenna radiation unit 22 and the GPS unit 23.

[0050] The beneficial effect of the above scheme is that the third glue layer is provided on the periphery of the antenna grounding unit 21, which not only enhances the stability of the antenna grounding unit 21, prevents the antenna grounding unit 21 from loosening or shifting during use, and reduces maintenance costs; it can also improve the waterproof and dustproof performance of the protective antenna through the sealing effect of the third glue layer. In addition, by connecting the antenna grounding unit 21 with the antenna radiation unit 22 and the GPS unit 23, and fixing the antenna grounding unit 21 to the inner wall of the upper cover 1 through the third glue layer, an effective electromagnetic shielding structure is formed, which helps to reduce the impact of external electromagnetic interference on the performance of the protective antenna and improves the stability and accuracy of the signal transmission of the protective antenna.

[0051] Furthermore, the fixing plate of the third rib 13 can be easily inserted into the second slot 202, and the first side of the antenna grounding unit 21 can be abutted against by the limiting step, so that the installation position of the antenna assembly 2 can be unified, which not only improves the accuracy of the installation, but also ensures the relative position relationship between the antenna assembly 2 and other components, which is beneficial to improving the overall performance; by inserting the second rib 12 into the first slot 201 and fixing it with the fastener 121, a close connection between the antenna grounding unit 21 and the upper cover 1 is achieved, which not only enhances the stability of the connection, effectively reduces the risk of performance degradation or damage due to looseness or vibration, but also simplifies the installation process and improves assembly efficiency.

[0052] The lower cover 3 of the utility model is installed on the second side of the antenna grounding unit 21, and the outer periphery of the lower cover 3 is provided with a first glue layer 51, which is used to fix the outer periphery of the lower cover 3 with the inner side wall of the upper cover 1, so as to close the opening of the upper cover 1. Figure 2 , when used, a second glue layer is provided between the second side of the antenna grounding unit 21 and the lower cover 3, for fixing the second side of the antenna grounding unit 21 to the lower cover 3. In actual application, a grid-shaped first rib 31 is provided on the side of the lower cover 3 facing the antenna grounding unit 21, which can not only enhance the mechanical strength of the lower cover 3, but also increase the bonding area between the lower cover 3 and the second glue layer, thereby improving the bonding strength between the lower cover 3 and the second glue layer, and ensuring the sealing and waterproof properties of the protective antenna. In some preferred embodiments, a through hole 32 is provided on the lower cover 3, and a second wire plug is provided on the through hole 32 for sealing the supply cable 4 through.

[0053] The beneficial effects of the above scheme are as follows: the outer periphery of the lower cover 3 is fixedly connected to the inner wall of the upper cover 1 through the first glue layer 51, which effectively closes the opening of the upper cover 1, enhances the sealing and waterproof performance of the overall structure, and can prevent foreign matter such as moisture and dust from entering the interior of the protective antenna, protecting the internal electronic components from damage, thereby improving the reliability and service life of the protective antenna.

[0054] Furthermore, a second glue layer is arranged between the second side of the antenna grounding unit 21 and the lower cover 3, which not only enhances the connection firmness between the antenna grounding unit 21 and the lower cover 3 and ensures the stability of the position of the antenna grounding unit 21, but also reduces the use of fasteners through the sealing effect of the second glue layer, reduces the electromagnetic interference and signal loss of the protective antenna, and improves the performance of the protective antenna.

[0055] Furthermore, a grid-shaped first rib 31 is provided on the side of the lower cover 3 facing the antenna grounding unit 21, which can not only enhance the mechanical strength of the lower cover 3 and increase the bonding area between the lower cover 3 and the second glue layer, but also optimize the transmission path of the electromagnetic wave, reduce the reflection and scattering of the electromagnetic wave, and further improve the performance of the protective antenna.

[0056] One end of the cable 4 of the present invention passes through the second wire plug of the through hole 32 and the wire plug 211 of the mounting hole in sequence, and is connected to the antenna grounding unit 21, the GPS unit 23 and the antenna radiation unit 22, and the other end of the cable 4 is connected to an external device. When used, the other end of the cable 4 can be connected to multiple terminals to achieve connection with different wireless signal transmitters.

[0057] During the assembly process of the protective antenna of the utility model: first pass the cable 4 through the lower cover 3 and the wire plug 211, and weld it with the antenna assembly 2 to ensure stable signal transmission; then align the first notch 201 and the second notch 202 on the antenna grounding unit 21 with the second rib position 12 and the third rib position 13 of the upper cover 1 respectively, and fix the antenna grounding unit 21 to the rib position of the upper cover 1 by screws or other fasteners 121, which not only improves the stability of the protective antenna, but also simplifies the assembly process of the protective antenna and reduces the error rate of the installation process. At this time, a layer of water can be applied to the periphery of the antenna grounding unit 21 in advance to form a third glue layer. Then apply a layer of glue on the second side of the antenna grounding unit 21 to form a second glue layer, and stick the lower cover 3 with glue on the periphery to the second side of the antenna grounding unit 21 coated with glue.

[0058] It can be seen that the protective antenna of the present application adopts a mis-installation method to install the antenna assembly 2 through the slots and ribs to prevent mis-installation, so as to be embedded in the upper cover 1. Figure 3 , which not only simplifies the assembly process, but also avoids the problem of unstable waterproof performance caused by assembly errors. At the same time, glue is poured on the second side of the antenna grounding unit 21, and the lower cover 3 and the upper cover 1 are installed in a notch-aligned manner, which not only ensures the waterproof and dustproof performance of the protective antenna, but also avoids the influence of glue on the performance of the protective antenna.

[0059] In summary, the upper cover 1 of the utility model is a hollow structure with one end open, which can provide an installation environment for the antenna assembly 2; the connection between the outer periphery of the antenna grounding unit 21 and the inner wall of the opening of the upper cover 1 can enhance the structural stability of the protective antenna; by arranging the first glue layer 51 on the outer periphery of the lower cover 3, the upper cover 1 and the lower cover 3 form a closed protective space, which can effectively prevent foreign matter such as moisture and dust from entering the interior of the protective antenna, and can avoid the protective space from being filled with glue, thereby ensuring that the antenna assembly 2 can operate normally and stably for a long time; based on the characteristics of the glue, even without using a waterproof pad, a sealing effect can be achieved, and based on the viscosity of the glue, the use of screws can be greatly reduced, thereby reducing the assembly error rate.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model.
