[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] One preferred embodiment of this application, such as Figures 1 to 4As shown, a high-strength radar radome includes a radome body 1, a base 2, and a shielding assembly 3. The base 2 and the radome body 1 are detachably mounted, and the radome body 1 has heat dissipation holes on its side. The radome body 1 also has a rainproof structure on its side to shield the heat dissipation holes. The shielding assembly 3 is mounted on the base 2 and cooperates with the heat dissipation holes. The shielding assembly 3 can deform according to temperature changes inside the radome body 1, thereby opening or closing the heat dissipation holes.

[0028] It should be understood that the primary function of a radome is to protect the antenna system from the influence of the external environment. Typically, the antenna system is installed within the mounting cavity of the radome housing 1, and high temperatures are generated within housing 1 during prolonged use. Existing radomes either lack heat dissipation capabilities or attempt to achieve this through perforated or modular structures on housing 1. However, these perforated or modular structures reduce the overall structural strength of the radome. Furthermore, radomes are typically used outdoors, where perforated or modular structures are insufficient to support prolonged use in natural environments.

[0029] Therefore, in this embodiment, a heat dissipation hole is provided on the side of the radome 1, and a shielding component 3 is provided on the base 2; the shielding component 3 can cooperate with the heat dissipation hole, and the shielding component 3 can open or close the heat dissipation hole, thereby dissipating heat from the radome.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, a first heat dissipation hole 100 is provided on the side of the cover 1; the shielding assembly 3 includes a driving member 33 and a shielding member 30; the shielding member 30 can cooperate with the driving member 33, and at the same time, the shielding member 30 also cooperates with the first heat dissipation hole 100. The driving member 33 can deform according to the temperature change inside the cover 1, thereby driving the shielding member 30 to move relative to the first heat dissipation hole 100, thereby opening or closing the first heat dissipation hole 100.

[0031] It is understandable that in order to better dissipate the temperature inside the cover 1, multiple sets of first heat dissipation holes 100 are provided. The multiple sets of first heat dissipation holes 100 are distributed at equal intervals along the circumference of the cover 1, while multiple first heat dissipation holes 100 in a single set are arranged along the axial direction of the cover 1.

[0032] It should be understood that the driving member 33 and the shielding member 30 can be arranged along the axial direction of the cover 1 and correspond to the positions of the multiple sets of first heat dissipation holes 100. When the temperature inside the cover 1 causes deformation, the driving member 33 deforms due to the temperature change, thereby driving the shielding member 30 to move relative to the multiple sets of first heat dissipation holes 100 along the axial direction of the cover 1, thereby opening or closing the multiple sets of first heat dissipation holes 100; however, the arrangement of the driving member 33 and the shielding member 30 along the axial direction of the cover 1 is not particularly convenient and not very stable.

[0033] Therefore, in this embodiment, the cover 1 has a recessed portion 10 on its side; the shielding member 30 is rotatably mounted on the recessed portion 10, and the shielding member 30 has multiple sets of second heat dissipation holes 300 on its side corresponding to the number and position of the first heat dissipation holes 100; the driving member 33 and the shielding member 30 are engaged by a rotating structure 32. The base 2 has a heat-gathering cavity 20, and the rotating structure 32 and the driving member 33 are mounted in the heat-gathering cavity 20. The driving member 33 can deform axially, thereby driving the shielding member 30 to rotate through the rotating structure 32, thereby opening or closing the first heat dissipation hole 100.

[0034] Understandably, the bottom end of the driving component 33 is connected to the bottom end of the heat-gathering cavity 20, while the end of the driving component 33 furthest from the heat-gathering cavity 20 contacts and engages with the bottom end of the rotating structure 32. After prolonged use of the antenna system, the internal temperature of the enclosure 1 will rise, causing the driving component 33 to undergo axial deformation due to the temperature change, which in turn causes the shielding component 30 to rotate via the rotating structure 32. When the multiple sets of second heat dissipation holes 300 on the side of the shielding component 30 correspond to the multiple sets of first heat dissipation holes 100 on the side of the enclosure 1, the interior of the enclosure 1 is in a heat dissipation state. When the internal temperature of the enclosure 1 returns to normal, the driving component 33 will also drive the rotating structure 32 to reset according to the temperature change, thereby causing the shielding component 30 to reset, and subsequently resetting the first heat dissipation holes 100.

[0035] In this embodiment, the rotation structure 32 is particularly important. The drive member 33 and the shielding member 30 cooperate through the rotation structure 32 to open or close the first heat dissipation hole 100. There are various ways to set the specific structure of the rotation structure 32. Two specific examples are given below, but the specific ways to set the rotation structure 32 are not limited to these two examples.

[0036] Example 1: such as Figure 3 As shown, the rotating structure 32 includes an upper rod section 320, a lower rod section 321, and a torsion spring 322; cams are provided on the opposite end faces of the upper rod section 320 and the lower rod section 321.

[0037] Specifically, the lower rod segment 321 can move axially upwards, thereby causing the upper rod segment 320 to rotate axially via the cam. The upper rod segment 320 is fixedly connected to the blocking member 30 at the end away from the cam, and the lower rod segment 321 is in contact with the driving member 33 at the end away from the cam. The torsion spring 322 is installed on the upper rod segment 320 and connected to the base 2. The driving member 33 can deform axially upwards due to temperature changes within the housing 1, thereby driving the lower rod segment 321 to move axially upwards, which in turn causes the upper rod segment 320 to rotate the blocking member 30. The blocking member 30 can be reset under the force of the torsion spring 322.

[0038] Example 2: such as Figure 4 As shown, the rotating structure 32 includes an upper rod section 320 and a lower rod section 321; the upper rod section 320 has a protrusion 3200 on its side wall, and the lower rod section 321 has a rotating groove 3211 on its side wall.

[0039] Specifically, the upper rod segment 320 is fixedly connected to the shielding member 30 at the end away from the protrusion 3200, and the lower rod segment 321 is connected to the driving member 33 at the end away from the rotating groove 3211. The driving member 33 is fixedly connected to the bottom of the heat-gathering cavity 20 at the end away from the lower rod segment 321. The driving member 33 can deform axially upwards due to temperature changes within the housing 1, thereby driving the lower rod segment 321 to move axially upwards, which in turn causes the upper rod segment 320 to rotate the shielding member 30. Simultaneously, when the temperature within the housing 1 returns to normal, the driving member 33 also deforms axially downwards due to temperature changes, thereby driving the lower rod segment 321 to move axially downwards, which in turn causes the upper rod segment 320 to rotate, thus resetting the shielding member 30.

[0040] It is understood that both of the above examples can meet the requirements of this application, and those skilled in the art can choose according to their actual needs.

[0041] It is also understandable that the driving component 33 deforms due to heat to drive the lower rod segment 321 to move. However, in actual use, the deformation of the driving component 33 may cause the lower rod segment 321 to rotate itself.

[0042] Therefore, in this embodiment, a connector 3210 is provided on the side of the lower rod segment 321, and a limiting cavity 200 is provided in the heat-gathering cavity 20; the lower rod segment 321 can be slidably connected to the limiting cavity 200 through the connector 3210, so that the lower rod segment 321 can only slide axially along the limiting cavity 200.

[0043] In this embodiment, as Figure 2 As shown, the rainproof structure is a conical baffle 11; the conical baffle 11 is connected to the outer side of the cover 1, and the middle part of the conical baffle 11 and the outer side of the cover 1 is hollow. However, multiple sets of first heat dissipation holes 100 are opened on the side wall of the cover 1, which may lead to the structural fragility of the cover 1 to some extent.

[0044] Therefore, in this embodiment, the conical baffle 11 and the outer side of the cover 1 are connected by a reinforcing rib 12 to strengthen the structure of the cover 1; at the same time, the reinforcing rib 12 is disposed between two adjacent sets of first heat dissipation holes 100.

[0045] In this embodiment, the material of the driving component 33 can be selected from various sources, such as shape memory metal, plastic, and other materials that can expand and contract with temperature changes. All of the above materials can meet the requirements of this application, and those skilled in the art can choose according to actual needs. In this embodiment, the shape memory metal material is preferred.

[0046] In this embodiment, the connection between the cover 1 and the base 2 can be achieved in various ways, such as a snap-fit ​​connection or a threaded connection using bolts 4, which are detachable connection methods. All of the above connection methods can meet the requirements of this application, and those skilled in the art can choose according to actual needs. In this embodiment, the threaded connection using bolts 4 is preferred.

[0047] In this embodiment, as Figure 3 As shown, in order to ensure the airtightness of the inside of the cover 1, a rubber pad 5 is also provided between the shield 30 and the inner recess 10. The rubber pad 5 is also provided with a number of holes and multiple sets of first heat dissipation holes 100 corresponding to each other.

[0048] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
