[0024] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0025] The specific implementation of this embodiment is described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1 , Figure 1 A possible structural schematic diagram of the radome provided in this embodiment is illustrated. In this embodiment, the radome may include an upper cover 100 and a lower cover 200.

[0027] A closed chamber may be formed between the upper cover 100 and the lower cover 200 , the upper cover 100 may include a first connecting portion 110 at an edge position, the lower cover 200 may include a second connecting portion 210 at an edge position, and the upper cover 100 and the lower cover 200 are connected via the first connecting portion 110 and the second connecting portion 210 .

[0028] In this embodiment, the shape and size of the upper cover 100 may be the same as the shape and size of the lower cover 200. When the shape of the upper cover 100 is a rectangle, the first connection portion 110 may be located at the four side positions of the rectangle, and the shape of the first connection portion 110 may be a closed rectangle. When the lower cover 200 is also a rectangle, the second connection portion 210 may be located at the four side positions of the rectangle, and the shape of the second connection portion 210 may be a closed rectangle. When the upper cover 100 and the lower cover 200 are connected through the first connection portion 110 and the second connection portion 210, the closed chamber may be formed between the upper cover 100 and the lower cover 200.

[0029] Please refer to Figure 2 The first connection portion 110 may include a groove 111 in which a sealing strip 300 is disposed, and the second connection portion 210 may include a boss 211 corresponding to the groove 111 .

[0030] In this embodiment, the groove 111 extends along the edge of the upper cover 100, and the shape of the groove 111 may be a closed rectangle. The boss 211 extends along the edge of the lower cover 200, and the shape of the boss 211 may be a closed rectangle. The cross-sectional shape of the boss 211 is the same as the cross-sectional shape of the groove 111. For example, when the cross-sectional shape of the groove 111 is a rectangle, the cross-sectional shape of the boss 211 is also a rectangle. The boss 211 and the groove 111 may cooperate with each other to achieve the connection between the upper cover 100 and the lower cover 200. When the upper cover 100 is connected to the lower cover 200, the boss 211 may compress the sealing strip 300 located in the groove 111 to prevent rainwater from penetrating into the closed chamber from the connection position between the upper cover 100 and the lower cover 200, thereby achieving a waterproof sealing effect.

[0031] In addition, the first connection portion 110 includes a side wall 120 at an edge thereof, and the side wall 120 contacts an edge of the second connection portion 210 . The side wall 120 contacts the second connection portion 210 in a step-like manner.

[0032] At the edge of the first connection part 110 and the second connection part 210, the first connection part 110 and the second connection part 210 are in step-like contact, so that water from different directions can be blocked from entering the sealed chamber. In addition, the sealed chamber also includes a waterproof chamber outside, which is located between the edge of the first connection part 110 and the second connection part 210 and the groove 111. There is a certain gap in the waterproof chamber. If water passes through the edge of the first connection part 110 and the second connection part 210 and enters the waterproof chamber, the water in the waterproof chamber can flow out from the gap, reducing the water pressure in the waterproof chamber, thereby reducing the waterproof pressure of the sealing strip 300.

[0033] In the above structure, by setting the groove 111 on the first connecting part 110, setting the boss 211 on the second connecting part 210, and installing the sealing strip 300 in the groove 111, when the boss 211 and the groove 111 cooperate with each other to achieve the connection between the upper cover 100 and the lower cover 200, the boss 211 can compress the sealing strip 300 located in the groove 111 to achieve a waterproof and dustproof sealing effect, thereby protecting the electrical components located in the sealing cavity and improving their service life.

[0034] In one possible implementation, see Figure 3 The sealing strip 300 may include a first arc-shaped convex surface 310 and a second arc-shaped convex surface 320 that are arranged opposite to each other. The first arc-shaped convex surface 310 and the second arc-shaped convex surface 320 may include two first arc-shaped protrusions 311 respectively.

[0035] The sealing strip 300 may further include a first side surface 330 and a second side surface 340 that are arranged opposite to each other. The first side surface 330 and the second side surface 340 are respectively connected between the first arc-shaped convex surface 310 and the second arc-shaped convex surface 320. The first side surface 330 and the second side surface 340 may respectively include two second arc-shaped protrusions 331.

[0036] The cross-sectional shapes of the first arc-shaped protrusion 311 and the second arc-shaped protrusion 331 may be semicircular, and the radius of the second arc-shaped protrusion 331 is smaller than the radius of the first arc-shaped protrusion 311 .

[0037] In this embodiment, the sealing strip 300 extends along the edge of the upper cover 100, the first arc-shaped protrusion 311 and the second arc-shaped protrusion 331 extend along the edge of the upper cover 100 respectively, the two first arc-shaped protrusions 311 of the first arc-shaped protrusion surface 310 correspond to the two second arc-shaped protrusions 331 of the second arc-shaped protrusion surface 320, and the two second arc-shaped protrusions 331 of the first side surface 330 correspond to the two second arc-shaped protrusions 331 of the second side surface 340.

[0038] In the above structure, by providing the first arc-shaped protrusion 311 and the second arc-shaped protrusion 331 on the sealing strip 300, the compression amount can be further increased when the sealing strip 300 is compressed, and line sealing is added on the basis of surface sealing, thereby improving the sealing effect.

[0039] In a possible implementation, the radius of the first arc-shaped protrusion 311 may include 0.65 mm, and the radius of the second arc-shaped protrusion 331 may include 0.1 mm.

[0040] In this embodiment, the height of the sealing strip 300 may be 9.5 mm, the width of the sealing strip 300 may be 2.8 mm, the first arc-shaped protrusion 311 may be a semicircle with a radius of 0.65 mm, and the second arc-shaped protrusion 331 may be a semicircle with a radius of 0.1 mm.

[0041] In a possible implementation, the height of the sealing strip 300 may be equal to the height of the groove 111 , and the material of the sealing strip 300 may include EPDM.

[0042] In this embodiment, the material of the sealing strip 300 can be EPDM, which is not only waterproof but also has a certain amount of compression. When the boss 211 is connected with the groove 111, the boss 211 can compress the sealing strip 300 so that the sealing strip 300 fills the groove 111, thereby achieving a sealing effect. EPDM is a type of rubber. EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated dienes. It is a type of ethylene-propylene rubber, represented by EPDM (Ethylene Propylene Diene Monomer). Because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, it has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance. It can be widely used in automotive parts, building waterproof materials, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals and other fields.

[0043] The height of the boss 211 may be 15%-25% of the height of the sealing strip 300 , and the compression amount of the sealing strip 300 may be 15%-25%.

[0044] In one possible implementation, see Figure 4 The lower cover 200 may include a first surface close to the sealed chamber and a second surface away from the sealed chamber, and the first interface 221 and the second interface 222 are respectively disposed on opposite sides of the second surface.

[0045] In this embodiment, a second groove 111 can be respectively provided on the two opposite sides of the second surface, and the first interface 221 and the second interface 222 can be respectively located in the second grooves 111 corresponding to the two side edges, and the first interface 221 and the second interface 222 can be used to realize the connection of multiple antenna bodies, and the first interface 221 and the second interface 222 can also be used for power supply and voltage control.

[0046] Specifically, an antenna body may be disposed in the sealed chamber, and the antenna body may be connected to the first interface 221 and the second interface 222 respectively.

[0047] In one possible implementation, please refer again to Figure 4 A working light 230 is provided on one side of the second surface close to the first interface 221 , and the working light 230 can be used to determine whether it is operating normally.

[0048] In this embodiment, the working light 230 may be located in the second groove 111 where the first interface 221 is located, and the number of the working light 230 may be one.

[0049] It should be noted that the work light 230 can also be located on the side of the second surface close to the second interface 222. The work light 230 is used to determine whether the system is operating normally. When the work light 230 is lit, it indicates that the system is operating normally. When the work light 230 is not lit, it indicates that the system has stopped working.

[0050] In one possible implementation, see Figure 5 and Figure 6 The first connection part 110 is also provided with a plurality of evenly distributed first connection holes 112, and the second connection part 210 is also provided with a plurality of evenly distributed second connection holes 212, the first connection holes 112 correspond to the second connection holes 212 one by one, and the first connection holes 112 and the second connection holes 212 can be connected by a connecting piece.

[0051] In this embodiment, the first connection hole 112 can be located on the side of the groove 111 away from the closed chamber, the first connection hole 112 protrudes from the surface of the first connection part 110, the second connection hole 212 can be located on the side of the boss 211 away from the closed chamber, the second connection hole 212 can be a through hole passing through the second connection part 210, the number of the first connection holes 112 is equal to the number of the second connection holes 212, the first connection hole 112 and the second connection hole 212 can be connected by the connecting piece, thereby further realizing the connection between the upper cover 100 and the lower cover 200, and improving the reliability of the connection between the upper cover 100 and the lower cover 200.

[0052] It should be noted that the connecting parts may include but are not limited to bolts, screws, etc., which are not specifically limited here.

[0053] In one possible implementation, please refer again to Figure 5 and Figure 6 First reinforcing ribs 113 are respectively arranged on both sides of the first connection hole 112, and second reinforcing ribs 213 are respectively arranged on both sides of the second connection hole 212.

[0054] In this embodiment, the first reinforcing rib 113 can be disposed on both sides of the first connecting hole 112, and the second reinforcing rib 213 can be disposed on both sides of the second connecting hole 212. The first reinforcing rib 113 and the second reinforcing rib 213 can be used to reduce deformation and improve overall rigidity.

Specifically, the antenna body located in the sealed chamber may be connected to the control system, and the control system may be connected to the first interface 221 and the second interface 222 provided on the lower cover 200, respectively.

[0060] To summarize, the present embodiment provides an antenna cover and an antenna, by setting a groove at the first connecting part, setting a boss at the second connecting part, and installing a sealing strip in the groove. When the boss and the groove cooperate with each other to realize the connection between the upper cover and the lower cover, the boss can compress the sealing strip located in the groove to achieve a waterproof and dustproof sealing effect, thereby protecting the electrical components located in the sealed cavity and improving their service life.
