Description

TECHNICAL FIELD

[0001] The application belongs to the field of antenna seat structure, and particularly relates to an antenna seat structure capable of adjusting assembly gap. BACKGROUND

[0002] In a radio frequency front-end system of an antenna seat, in order to reduce the signal transmission loss between a feed device and an antenna unit, the antenna unit is often directly connected with a front-end microwave assembly. The front-end microwave assembly often generates a large amount of heat, and its thermal design needs to be considered. If a natural heat dissipation design is adopted, in a traditional structure scheme, a rigid connection body composed of the antenna unit and the front-end microwave assembly is fixed from the bottom. The upper surface of the front-end microwave assembly is in contact with a heat dissipation cover plate of the antenna seat, and heat is transmitted to the external space through the heat dissipation cover plate. In order to reduce the thermal resistance, the front-end microwave assembly needs to be tightly attached to the heat dissipation cover plate. However, according to the assembly sequence, the heat dissipation cover plate which is installed last has an over-positioning constraint, that is, the heat dissipation cover plate needs to be pressed against its own installation surface and the front-end microwave assembly. Affected by the cumulative errors of machining and assembly, it is difficult to control the gap size between the heat dissipation cover plate and the front-end microwave assembly. If the gap is too large, the thermal resistance will be significantly increased, which affects the heat dissipation effect of the front-end microwave assembly; if the gap is negative (that is, the heat dissipation cover plate interferes with the front-end microwave assembly), the sealing effect of the heat dissipation cover plate and the antenna seat shell is affected, and the water tightness of the antenna seat is damaged. At present, there is a lack of an antenna seat structure which can realize good heat conduction and meet the installation sealing effect. SUMMARY

[0003] The application provides an antenna seat structure capable of adjusting assembly gap.

[0004] The technical scheme for achieving the purpose of the application is as follows: an antenna seat structure capable of adjusting assembly gap, comprising:

[0005] a column lens antenna, a plurality of front-end microwave assemblies, a heat dissipation cover plate, a wedge-shaped heat conduction block, a fixing frame and an antenna seat shell, the column lens antenna is fixed on the antenna seat shell, the heat dissipation cover plate is fixed on the antenna seat shell, and the input waveguide port end surface of the front-end microwave assembly is connected and fixed with the output waveguide port end surface of the column lens antenna through a long screw rod; the wedge-shaped heat conduction block is arranged above the front-end microwave assembly, the fixing frame is located below the front-end microwave assembly, the heat dissipation cover plate is located above the wedge-shaped heat conduction block, and the fixing frame and the heat dissipation cover plate are fixed so as to fix the whole formed by the front-end microwave assembly and the wedge-shaped heat conduction block between the fixing frame and the heat dissipation cover plate, and the gap between the wedge-shaped heat conduction block and the heat dissipation cover plate is adjusted by adjusting the wedge-shaped heat conduction block.

[0006] Preferably, the first wedge-shaped surface of the heat dissipation cover plate is attached to the second wedge-shaped surface of the wedge-shaped heat conduction block.

[0007] Preferably, the heat-conducting surface of the front-end microwave component is provided with a waist-shaped mounting hole, which corresponds to the threaded hole on the lower surface of the wedge-shaped heat-conducting block. The relative installation position of the front-end microwave component and the wedge-shaped heat-conducting block is moved by using the waist-shaped mounting hole on the heat-conducting surface of the front-end microwave component, thereby adjusting the gap between the first wedge-shaped surface of the heat dissipation cover and the second wedge-shaped surface of the wedge-shaped heat-conducting block.

[0008] Preferably, the wedge-shaped heat-conducting block has a first through hole, and a long screw passes through the first through hole and is connected and fixed to the end face of the output waveguide of the cylindrical lens antenna.

[0009] Preferably, the mounting bracket has a second through hole, through which a long screw passes and is connected and fixed to the end face of the output waveguide port of the cylindrical lens antenna.

[0010] Preferably, the side of the heat dissipation cover away from the wedge-shaped heat-conducting block is provided with heat dissipation teeth.

[0011] Preferably, after the thermally conductive surface of the front-end microwave component is coated with thermally conductive silicone grease, it is attached to the lower surface of the wedge-shaped thermally conductive block, and the front-end microwave component and the wedge-shaped thermally conductive block are fixedly connected by fasteners.

[0012] Preferably, a thin elastic rubber pad is filled between the contact surfaces of the mounting bracket and the front-end microwave assembly to press the front-end microwave assembly tightly.

[0013] This invention also proposes an assembly method for an antenna mount structure with adjustable assembly gap, comprising:

[0014] Mount the cylindrical lens antenna on the antenna mount housing; apply thermal grease to the thermally conductive surface of the front-end microwave component and attach it to the lower surface of the wedge-shaped heat-conducting block; use fasteners to connect the front-end microwave component and the wedge-shaped heat-conducting block vertically; attach the input waveguide port end face of the front-end microwave component to the output waveguide port end face of the cylindrical lens antenna, and use a long screw to connect the front-end microwave component and the cylindrical lens antenna; use fasteners to fix the heat dissipation cover plate to the outer surface of the antenna mount housing. Thermal grease is applied to the first wedge-shaped surface of the heat sink cover. When there is a gap or interference between the first wedge-shaped surface of the heat sink cover and the second wedge-shaped surface of the wedge-shaped heat conductor, the fasteners of the front-end microwave component and the wedge-shaped heat conductor are loosened, and the position of the wedge-shaped heat conductor is adjusted back and forth to make the first wedge-shaped surface of the heat sink cover fit tightly with the second wedge-shaped surface. The fasteners of the front-end microwave component and the wedge-shaped heat conductor are then tightened. The long screw passes through the second through hole of the fixing bracket and is connected and fixed to the end face of the output waveguide of the cylindrical lens antenna. The fixing bracket fits the front-end microwave component and the wedge-shaped heat conductor from bottom to top and fits against the mounting boss of the heat sink cover. The fixing bracket and the heat sink cover are connected and fixed with fasteners.

[0015] Compared with the prior art, the significant advantages of this invention are:

[0016] (1) The present invention uses wedge blocks to adjust the assembly gap, ensuring good contact between the front microwave component and the heat dissipation cover, improving the heat dissipation effect, and satisfying the installation sealing effect between the heat dissipation cover and the antenna housing.

[0017] (2) When repairing the microwave component at the front end of the vulnerable part, the present invention does not require disassembling the heat dissipation cover plate located above the antenna base. It can be operated through the space behind the antenna base, further reducing the risk of water leakage from the antenna base.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0024] like Figure 1 , 2 As shown, the present invention provides an antenna mount structure with adjustable assembly gap, including a cylindrical lens antenna 1, multiple front-end microwave components 2, and connecting structural components (heat dissipation cover 3, wedge-shaped heat conduction block 4, fixing frame 5, long screw 6, and antenna mount housing 7).

[0025] like Figures 2-5 As shown, the overall structure of an antenna mount with adjustable assembly gap is as follows: a cylindrical lens antenna 1 and a front-end microwave component 2 are mounted front and rear, with the output waveguide end face 11 of the cylindrical lens antenna 1 fitting against the input waveguide end face 21 of the front-end microwave component 2. A heat dissipation cover 3 and a wedge-shaped heat-conducting block 4 are stacked vertically with the front-end microwave component 2. The assembly gap is adjusted by changing the relative installation positions of the wedge-shaped heat-conducting block 4 and the front-end microwave component 2, ensuring that the first wedge-shaped surface 31 of the heat dissipation cover 3 fits against the second wedge-shaped surface 41 of the wedge-shaped heat-conducting block 4, and the heat-conducting surface 22 of the front-end microwave component 2 fits against the lower surface 42 of the wedge-shaped heat-conducting block 4. The heat dissipation cover 3 is mounted on the outer surface of the antenna mount housing 7, and the outer side of the heat dissipation cover 3 has heat dissipation teeth 32.

[0026] To facilitate understanding of the structural form of this invention, the following description follows the assembly sequence. For example...Figure 2 , 3 As shown in Figure 4, the heat-conducting surface 22 of the front-end microwave component 2 has a waist-shaped mounting hole 23, which corresponds to the threaded hole on the lower surface 42 of the wedge-shaped heat-conducting block 4. Fasteners are used to connect the front-end microwave component 2 and the wedge-shaped heat-conducting block 4 vertically. At this time, the heat-conducting surface 22 of the front-end microwave component 2 is in contact with the lower surface 42 of the wedge-shaped heat-conducting block 4.

[0027] The mounting hole on the input waveguide end face 21 of the front-end microwave component 2 corresponds to the threaded hole on the output waveguide end face 11 of the cylindrical lens antenna 1. A long screw 6 is used to connect the front-end microwave component 2 and the cylindrical lens antenna 1 from left to right. At this time, the input waveguide end face 21 of the front-end microwave component 2 and the output waveguide end face 11 of the cylindrical lens antenna 1 are in contact. The long screw 6 above the front-end microwave component 2 passes through the first through hole 43 of the wedge-shaped heat-conducting block 4.

[0028] The cylindrical lens antenna 1, the front-end microwave component 2, and the wedge-shaped heat-conducting block 4 are connected together to form a whole, which is then vertically connected to the heat dissipation cover 3 located above by a mounting bracket 5. The mounting holes on the mounting bracket 5 correspond to the threaded holes on the heat dissipation cover 3. Fasteners are used to connect the mounting bracket 5 and the heat dissipation cover 3 vertically, while the mounting bracket also covers the whole formed by the cylindrical lens antenna 1, the front-end microwave component 2, and the wedge-shaped heat-conducting block 4. The mounting bracket 5 has a second through hole 51, which can avoid the long screw 6 below the front-end microwave component 2.

[0029] Since the first wedge-shaped surface 31 of the heat dissipation cover 3 and the second wedge-shaped surface 41 of the wedge-shaped heat-conducting block 4 have the same slope, the two wedge-shaped surfaces are parallel. Due to the cumulative errors in processing and assembly, there may be gaps or interference between the two wedge-shaped surfaces. At this time, by using the waist-shaped mounting hole 23 on the heat-conducting surface 22 of the front-end microwave component 2, the front-end microwave component 2 and the wedge-shaped heat-conducting block 4 can be moved to adjust the relative installation positions of the front-end microwave component 2 and the wedge-shaped heat-conducting block 4, thereby adjusting the gap between the first wedge-shaped surface 31 of the heat dissipation cover 3 and the second wedge-shaped surface 41 of the wedge-shaped heat-conducting block 4, so that they fit tightly together.

[0030] Example

[0031] To verify the effectiveness of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] See Figure 1 , 2 The antenna mount structure with adjustable assembly gap in this embodiment mainly consists of a cylindrical lens antenna 1, multiple front-end microwave components 2, a heat dissipation cover plate 3, a wedge-shaped heat-conducting block 4, a fixing frame 5, and a long screw 6.

[0033] The assembly sequence is as follows:

[0034] The cylindrical lens antenna 1 is mounted on the antenna housing 7, with its output waveguide port end face 11 facing rearward.

[0035] like Figure 2 , 3 As shown in Figure 4, after applying thermal grease to the thermally conductive surface 22 of the front-end microwave component 2, it is attached to the lower surface 42 of the wedge-shaped thermally conductive block 4, and fasteners are used to connect the front-end microwave component 2 and the wedge-shaped thermally conductive block 4 vertically.

[0036] After attaching the input waveguide end face 21 of the front-end microwave component 2 to the output waveguide end face 11 of the cylindrical lens antenna 1, the front-end microwave component 2 and the cylindrical lens antenna 1 are connected left and right using a long screw 6. The long screw 6 above the front-end microwave component 2 needs to pass through the first through hole 43 of the wedge-shaped heat-conducting block 4.

[0037] The heat sink cover 3 is fixed to the outer surface of the antenna mount housing 7 using fasteners. The first wedge-shaped surface 31 of the heat sink cover 3 faces downward, and thermal grease is applied to the first wedge-shaped surface 31.

[0038] If there is a gap or interference between the first wedge-shaped surface 31 of the heat dissipation cover 3 and the second wedge-shaped surface 41 of the wedge-shaped heat-conducting block 4, loosen the fasteners of the front microwave assembly 2 and the wedge-shaped heat-conducting block 4, adjust the position of the wedge-shaped heat-conducting block 4 back and forth so that the first wedge-shaped surface 31 and the second wedge-shaped surface 41 fit tightly together, and tighten the fasteners of the front microwave assembly 2 and the wedge-shaped heat-conducting block 4.

[0039] The mounting bracket 5 is passed through the long screw 6 from back to front, and then fitted onto the front microwave component 2 from bottom to top, fitting snugly against the mounting boss of the heat sink cover 3. Fasteners are used to connect the mounting bracket 5 and the heat sink cover 3 vertically. A thin elastic rubber pad is filled between the contact surfaces of the mounting bracket 5 and the front microwave component 2 to press the front microwave component 2 firmly.

[0040] In summary, the structure of this invention allows for adjustment of the assembly gap via wedge blocks, ensuring good contact between the front-end microwave component and the heat dissipation cover, thereby improving heat dissipation and achieving a good sealing effect between the heat dissipation cover and the antenna mount housing. Furthermore, when repairing the vulnerable front-end microwave component, it is not necessary to disassemble the heat dissipation cover located above the antenna mount; operation can be performed simply through the space behind the antenna mount, further reducing the risk of water leakage from the antenna mount.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
