Technical Field

[0001] The present invention relates to the technical field of antennas, and more particularly, to a waterproof radome and a waterproof antenna. Background Art

[0002] In the field of antennas, especially external antennas such as those on drones, certain waterproof treatments are usually required to prevent external rainwater from entering the inside of the radome, which may cause the failure of the antenna function. Since the antenna components need to be disassembled and assembled inside the radome and subsequent maintenance is also required, it is difficult to completely adopt an integral configuration or completely seal it with sealant. Therefore, in the prior art, the bottom plate is usually directly fixed to the radome with screws to form a closed space. However, due to a certain gap between the bottom plate and the radome, its waterproof performance is limited, resulting in a decline in the waterproof performance of the radome after long-term use or after maintenance disassembly and assembly, and the waterproof sealing effect is poor. Summary of the Invention

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work fall within the scope of protection of the present invention.

[0027] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0029] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0030] As disclosed in the background art, for the radome in the prior art, due to the direct assembly of the direct bottom plate and the fixing method by screws, its waterproof effect is poor. Moreover, there are other problems with the existing antennas using screw connections. Specifically, the screws can be arranged outside the radome or on the bottom plate. Since the radome is processed from non-metallic materials, if fixed from the outside of the radome to the bottom plate inward, various countersunk holes will be processed on the radome, which is neither beautiful nor will it affect the aerodynamic layout of the entire radome; if fixed from the bottom plate to the radome outward, then a wire insert must be embedded inside the radome. However, in actual use, embedding a wire insert inside a non-metallic material is very unreliable. After being disassembled several times, the wire insert is very easy to fall out and has a low service life.

[0031] In addition, special tooling is required to ensure the machining accuracy for processing countersunk holes on the circumference of the radome, and there are also high requirements for the uniform spacing of the screws. Otherwise, after the screws are tightened, the screws will warp due to the pressure between them, resulting in the final sealing failure. Once the sealing fails, the circuit board inside the antenna is likely to short-circuit and burn out, and the antenna surface will also be corroded, ultimately causing the entire antenna to malfunction, which belongs to a serious quality accident.

[0032] To solve the above problems, the embodiment of the present invention provides a waterproof radome with good waterproof effect, convenient installation and high service life.

[0033] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] First Embodiment

[0035] Please refer to Figures 1 to 5 , this embodiment provides a waterproof radome 100 with good waterproof effect, convenient installation and high service life.

[0036] The waterproof radome 100 provided in this embodiment includes a cover body 110, a sealing insert 130, and a bottom plate 150. The bottom of the cover body 110 has an opening 110a. The sealing insert 130 is disposed around the opening 110a and is hermetically connected to the bottom of the cover body 110. The bottom plate 150 covers the opening 110a and is detachably connected to the sealing insert 130. A sealing ring 170 is provided between the sealing insert 130 and the bottom plate 150 to enable the bottom plate 150 and the sealing insert 130 to be hermetically connected.

[0037] In this embodiment, the cover body 110 is hemispherical. The bottom plate 150 and the cover body 110 enclose a closed space. An opening 110a for loading the antenna assembly is formed at the bottom of the cover body 110. The antenna assembly is disposed on the surface of the bottom plate 150. When the bottom plate 150 covers the opening 110a, the antenna assembly is accommodated in the closed space, playing a sealing role.

[0038] In this embodiment, the sealing insert 130 is a metal insert and is fixed to the bottom of the cover body 110 by an ultrasonic welding process. To avoid electromagnetic shielding, the cover body 110 is made of a non-metallic material with low wave transmission loss and low dielectric constant. Preferably, it is made of rubber. Through the ultrasonic welding process, the sealing insert 130 can be fixed to the bottom of the cover body 110 and is hermetically connected to the cover body 110. Of course, the sealing insert 130 can also be made of other materials here, such as alloy or hard plastic, etc., which are not specifically limited herein.

[0039] In other preferred embodiments of the present invention, the sealing insert 130 can also be bonded to the bottom of the cover body 110 with a sealant, which can also achieve a sealed connection.

[0040] In this embodiment, a plurality of first card slots 110b are formed at the bottom of the cover body 110. A plurality of first bosses 131 are provided on the sealing insert 130. The plurality of first bosses 131 are respectively embedded in the plurality of first card slots 110b. Specifically, 12 first card slots 110b are evenly distributed at the bottom of the cover body 110, and 12 first bosses 131 are evenly provided on the upper surface of the sealing insert 130. The shape of the first boss 131 matches the shape of the first card slot 110b. After the first boss 131 is assembled in the first card slot 110b, the first boss 131 and the first card slot 110b are fixed and sealed as a whole by an ultrasonic welding process. Of course, the number of the first bosses 131 and the first card slots 110b here is only an example and does not play a limiting role.

[0041] In this embodiment, a plurality of first screw holes 133 are formed in the sealing insert 130, and a plurality of second screw holes 151 are correspondingly formed in the bottom plate 150. A connecting screw extending into the corresponding first screw hole 133 is assembled in each second screw hole 151. Specifically, a plurality of first screw holes 133 are formed in the bottom surface of the sealing insert 130, and the plurality of first screw holes 133 correspond to the plurality of first bosses 131 one by one. Each first screw hole 133 extends upward from the bottom side of the sealing insert 130 into the first boss 131, so that the axial distance of the first screw hole 133 reaches the maximum.

[0042] It should be noted that in this embodiment, the sealing insert 130 is in the shape of an annular plate, and the first screw holes 133 are formed at the first bosses 131 on the sealing insert 130 to ensure that the axial distance of the first screw holes 133 is large enough.

[0043] During actual assembly, the sealing insert 130 is fixed to the bottom of the cover 110 by ultrasonic welding technology and is arranged around the opening 110a in a ring shape. The bottom plate 150 is covered on the opening 110a, and then connecting screws are assembled on each second screw hole 151. The connecting screws are assembled upward and extend into the first screw holes 133, so that the bottom plate 150 and the sealing insert 130 are fixed as a whole.

[0044] In this embodiment, a relief ring groove 110c is formed in the bottom of the cover 110. The sealing insert 130 is arranged in the relief ring groove 110c. An assembly ring platform 153 matching the relief ring groove 110c is arranged on the bottom plate 150. The sealing ring 170 is pressed between the sealing insert 130 and the assembly ring platform 153. Specifically, the first clamping groove 110b is arranged in the relief ring groove 110c. The sealing insert 130 is assembled in the relief ring groove 110c, and the first boss 131 on the sealing insert 130 is correspondingly assembled in the first clamping groove 110b in the relief ring groove 110c. The depth of the relief ring groove 110c is greater than the thickness of the sealing insert 130, so that after the sealing insert 130 is inserted into the relief ring groove 110c, the assembly ring platform 153 can also be inserted into the relief ring groove 110c.

[0045] In this embodiment, the relief ring groove 110c is an open ring groove, which is communicated with the opening 110a. The outer surface of the sealing insert 130 along the radial direction abuts against the side wall of the relief ring groove 110c, and the inner surface of the sealing insert 130 along the radial direction is flush with the inner surface of the bottom of the cover 110 in the same direction, that is, the shape and size of the sealing insert 130 match the shape and size of the relief ring groove 110c.

[0046] It should be noted that in this embodiment, the assembly ring platform 153 is inserted into the relief ring groove 110c, and the surface of the bottom plate 150 around the assembly ring platform 153 abuts against the bottom surface of the cover body 110 around the relief ring groove 110c. A stepped structure is formed by assembling the relief ring groove 110c and the assembly ring platform 153, further ensuring the sealing effect at the joint.

[0047] In this embodiment, a stop and guide convex ring 155 is further provided on the inner edge of the assembly ring platform 153. The stop and guide convex ring 155 is used to abut against the inner surface of the sealing insert 130. Specifically, the outer diameter of the stop and guide convex ring 155 is in radial fit with the inner diameter of the sealing insert 130, so that when the stop and guide convex ring 155 extends into the opening 110a, it can abut against the inner surface of the sealing insert 130. Preferably, the height of the stop and guide convex ring 155 in the axial direction is greater than the thickness of the sealing insert 130, so that the stop and guide convex ring 155 can extend into the opening 110a and abut against the inner surface of the bottom of the cover body 110.

[0048] During the actual assembly of the bottom plate 150, the stop and guide convex ring 155 on the bottom plate 150 also plays a guiding role, enabling the stop and guide convex ring 155 to be assembled in the opening 110a and achieving rapid assembly. At the same time, the stop and guide convex ring 155 and the assembly ring platform 153 also form a stepped structure, ensuring the reliability of the assembly.

[0049] In this embodiment, a sealing ring groove 157 is further provided on the assembly ring platform 153. The sealing ring 170 is partially accommodated in the sealing ring groove 157. Specifically, the sealing ring 170 is a rubber ring, and the shape of the rubber ring matches the shape of the sealing ring groove 157. The sealing ring 170 is partially accommodated in the sealing ring groove 157, and the rest protrudes from the sealing ring groove 157 and deforms under the pressing action of the bottom surface of the sealing insert 130, so that the top surface of the sealing insert 130 and the surface of the assembly ring platform 153 are sealed and connected through the sealing ring 170.

[0050] It should be noted that in this embodiment, by embedding the sealing insert 130 made of metal at the bottom of the non-metal cover body 110 made of non-metal material, the reliability and accuracy of machining the first screw hole 133 are ensured. Combined with the setting of the sealing ring 170, the problem of unreliable sealing is effectively solved.

[0051] The cover body 110 includes a top cover 111, a support cover 113, and a base 115. The top cover 111 is disposed on the top side of the support cover 113, the support cover 113 is arranged on the base 115. The top cover 111 and the support cover 113 are hermetically joined together as a whole, and the support cover 113 and the base 115 are hermetically joined together as a whole. An opening 110a is provided on the bottom side of the base 115. Specifically, the cover body 110 has a hemispherical structure. The top cover 111, the support cover 113, and the base 115 are of a split structure, divided into upper, middle, and lower parts, and each part is hermetically joined together to ensure a good waterproof effect.

[0052] It should be noted that in this embodiment, the top cover 111, the support cover 113, and the base 115 are all made of non-metallic materials. In this embodiment, the cover body 110 is designed in a split manner during processing, which avoids the difficulty in purchasing raw materials during overall processing, ensures the processing accuracy, reduces the manufacturing difficulty, and effectively reduces the manufacturing cost.

[0053] In this embodiment, a plurality of clamping tabs 113a are provided on the top side of the support cover 113, and a plurality of clamping relief grooves 111a are formed on the edge of the top cover 111. The plurality of clamping tabs 113a are respectively assembled in the plurality of clamping relief grooves 111a. Specifically, 4 clamping tabs 113a are provided on the top side edge of the support cover 113, and 4 clamping relief grooves 111a are formed on the edge of the top cover 111. During assembly, the 4 clamping tabs 113a are correspondingly assembled in the 4 clamping relief grooves 111a. The clamping tabs 113a and the clamping relief grooves 111a play a role in limiting and connecting. Of course, the quantity here is only for illustration and does not serve as a limitation.

[0054] In other preferred embodiments of the present invention, it may also be that a clamping relief groove 111a is provided on the top side of the support cover 113, and a plurality of clamping tabs 113a are provided on the edge of the top cover 111, which can also play a role in limiting and connecting.

[0055] It should be noted that in this embodiment, the protruding height of the clamping tab 113a is matched with the relief depth of the clamping relief groove 111a, so that the edge of the top cover 111 abuts against the top side edge of the support cover 113 to complete the splicing action.

[0056] In this embodiment, the support cover 113 and the top cover 111 are bonded together as a whole by sealant to ensure the sealing effect at the joint. Of course, here the support cover 113 and the top cover 111 can also be fixed together as a whole by ultrasonic welding process, which can also ensure the sealing effect at the joint.

[0057] In this embodiment, the clamping tab 113a has a stepped structure with transverse and vertical protrusions. The shape of the clamping relief groove 111a is matched with that of the clamping tab 113a. Through the clamping tab 113a with a boss structure, the contact area between it and the clamping relief groove 111a is greatly increased, so that the bonding force between the support cover 113 and the top cover 111 is greatly enhanced, ensuring the integrity of the cover body 110. Specifically, during assembly, a strong adhesive is applied to the transverse and vertical protrusions on the clamping boss, so that the top cover 111 and the support cover 113 are bonded together, and then sealant is applied to the joint to ensure the sealing effect.

[0058] In other preferred embodiments of the present invention, the clamping tab 113a and the clamping relief groove 111a can also be other shapes, such as serrated or rectangular, etc., which are not specifically limited herein.

[0059] In this embodiment, a plurality of second bosses 115a are provided on the base 115, and a plurality of second clamping grooves 113b are provided at the bottom of the support cover 113. The plurality of second bosses 115a are matched with the plurality of second clamping grooves 113b. Specifically, 6 second bosses 115a are provided on the base 115, and 6 second clamping grooves 113b are provided at the bottom of the support cover 113. The 6 second bosses 115a and the 6 second clamping grooves 113b are assembled in one-to-one correspondence, so as to play a role in limiting and connecting. Of course, the quantity here is only for illustration and does not serve as a limitation.

[0060] In this embodiment, the support cover 113 and the base 115 are bonded together by sealant to ensure the sealing effect at the joint. Of course, the support cover 113 and the base 115 can also be fixed together by ultrasonic welding process here, which can also ensure the sealing effect at the joint.

[0061] During actual assembly, first, the top cover 111, the support cover 113 and the base 115 are spliced together, and after applying a little sealant, a hemispherical cover body 110 is formed. Then, the sealing insert 130 is fixed to the bottom of the cover body 110 by ultrasonic welding process and is arranged around the opening 110a in a ring shape. Then, the bottom plate 150 with the antenna assembly is covered on the opening 110a, and the stop guiding convex ring 155 is used for guiding assembly. After the screw holes are aligned, the bottom plate 150 and the sealing insert 130 are fixed together by connecting screws. Finally, sealant is applied at the screw connection to make the whole in a waterproof and sealed state and ensure that the waterproof level reaches IP65.

[0062] In summary, a waterproof radome 100 provided by this embodiment has a sealing insert 130 disposed at the bottom of the radome body 110 and is hermetically connected to the sealing insert 130. Meanwhile, the bottom plate 150 is covered on the bottom of the radome body 110, and a sealing ring 170 is disposed between the bottom plate 150 and the sealing insert 130, so that a sealed connection is also achieved between the bottom plate 150 and the sealing insert 130. At the same time, the bottom plate 150 and the sealing insert 130 are detachably connected. When disassembling and assembling, the bottom plate 150 can be removed, which is very convenient. After the bottom plate 150 is assembled, sealing is achieved through the sealing ring 170, the sealing effect is good, and the sealing structure is stable and reliable. Meanwhile, the sealing insert 130 made of metal is adopted, so that the connection between the bottom plate 150 and the sealing insert 130 is more reliable and stable, the situation of screw thread failure during the disassembly process is avoided, and the service life of the screw connection is improved. Moreover, the radome body 110 adopts a split design, which avoids the difficulty in purchasing raw materials during integral processing, ensures the processing accuracy, reduces the manufacturing difficulty, and effectively reduces the manufacturing cost.
