Description
Technical field
The present invention relates to phased array antenna technical fields.More particularly, to a kind of phased array antenna front frame.
Background technique
Front frame is the main load-carrying member of massive phased array antenna, and the quality of rigidity directly determines that antenna is electrical
The accurate realization of index.Existing frequently-used antenna array frame form has aluminium sheet by way of bolt splices, aluminium sheet welding side
Formula and the mode for directly drawing profile.Aluminium sheet by way of bolt splices, want by the rigidity that can not meet massive phased array antenna
It asks.The deformation of aluminium sheet welding mode welded stress is unfavorable to massive phased array antenna electrical specifications.In addition to the above aluminium sheet passes through spiral shell
It, can also be by way of directly drawing profile outside the form of bolt splicing, this mode can satisfy antenna rigidity requirement, but existing
There is profile sectional dimension small, section type is more, it is difficult to meet that massive phased array day Line stiffness is big, deform small, light-weight requirement.
Summary of the invention
It is an object of the present invention to provide a kind of phased array antenna front frame, provide that a kind of structure is simple, weight
Gently, the front frame that rigidity is big and deformation is small.
In order to achieve the above objectives, the present invention adopts the following technical solutions:
The invention discloses a kind of phased array antenna front frame, the front frame include outer framework open at one end with
And the space that the outer framework surrounds is separated to form enclosure space and crossbeam with the open space of the open communication.
Preferably, the frame is formed by aluminum alloy materials.
Preferably, the frame is to be formed by drawing.
Preferably, the outer framework is rectangular frame open at one end.
Preferably, two corners of the rectangular frame far from the opening are respectively equipped with reinforcing rib.
Preferably, the enclosure space is for being routed.
Preferably, two ends that the outer framework corresponds to the opening are used to be welded to connect with external structure.
Beneficial effects of the present invention are as follows:
Outer framework open at one end is divided into enclosure space and open space, the outline border of enclosure space by crossbeam by the present invention
Frame may be used primarily for load, can be also used for being routed in enclosure space, and the opening of open space can be used for connecting with external structure
It connects, the present invention provides the multiple uses such as load and connection by the composite construction of enclosure space and open space, and has knot
Structure is simple, light-weight, rigidity is big, the small advantage low with processing cost of deformation.
Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 shows a kind of sectional view of one specific embodiment of phased array antenna front frame of the invention.
Specific embodiment
In order to illustrate more clearly of the present invention, the present invention is done further below with reference to preferred embodiments and drawings
It is bright.Similar component is indicated in attached drawing with identical appended drawing reference.It will be appreciated by those skilled in the art that institute is specific below
The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
According to an aspect of the present invention, present embodiment discloses a kind of phased array antenna front frames.As shown in Figure 1,
In the present embodiment, phased array antenna front frame includes open at one end 13 outer framework 1 and the sky that surrounds the outer framework 1
Between the crossbeam 2 of open space 4 that is separated to form enclosure space 3 and is connected to the opening 13.
The phased array antenna front frame of the present embodiment is divided open at one end 13 outer framework 1 for envelope by setting crossbeam 2
Space 3 and open space 4 are closed, the outer framework 1 of enclosure space 3 may be used primarily for load, can be also used for cloth in enclosure space 3
Line, and the opening 13 of open space 4 can be used for connecting with external structure, the present invention are answered by enclosure space 3 and open space 4
It closes structure and provides the multiple uses such as load and connection, and simple, light-weight, rigidity is greatly with structure, deformation is small and is processed into
This low advantage.
In a preferred embodiment, the rectangular frame that the outer framework 1 is open at one end 13.It is furthermore preferred that the square
Shape frame is respectively equipped with reinforcing rib 14 far from two corners of the opening 13.Then the section of phased array antenna front frame due to
The setting of crossbeam 2 and reinforcing rib 14 is formed similarly to the compound cross-section of D type section and C-shaped cross section.Wherein, D type section can be made
For main load section, while can be used for being routed.C-shaped cross section can be used for the connection with other structures part, such as C-shaped cross section
The end of opening 13 can be used for being welded to connect with external connection.In addition, being used for after also C-shaped cross section being processed removal when in use
More small-sized phased array antenna front frame.
The section of the front frame of the present embodiment is main load-carrying surface by setting D type section, and hollow space can be routed,
C-shaped cross section and other structures are welded, so that welded connecting face and main load-carrying surface are separately effectively reduced welding deformation to day
The influence of line, while D and C-shaped cross section is compound can take into account the use compared with miniature antenna profile, reduce profile type.
In a preferred embodiment, the frame can be formed by aluminum alloy materials, to obtain good strength characteristics.
In a preferred embodiment, the frame can be formed by drawing.Specifically, large-scale puller system and spy can be passed through
Aluminum alloy materials are drawn into the front frame with compound cross-section by fixed mold.
In the present embodiment, the sectional dimension of phased array antenna front frame is as shown in Figure 1.Phased array antenna front frame
Line density is 118.6kg/m, and the length of every front frame can be 8m or 4m.Wherein, the width of outer framework 1 is 466mm, height
For 276mm, side 12 is with a thickness of 36mm, and top 11 is with a thickness of 31mm；The height of the enclosure space 3 is 157mm, and crossbeam 2 is thick
Degree is 28mm.The side 12 of the crossbeam 2 and the outer framework 1 is formed with the fillet of R10mm, in the present embodiment, in frame
Length direction is equipped with 14 fillets.The section of reinforcing rib 14 is triangle, length of the reinforcing rib 14 in 1 width direction of outer framework
It is 20.4mm in the length of 1 short transverse of outer framework for 40.7mm.The lower end and 1 side 12 of outer framework of the reinforcing rib 14 are also
Reinforcing steel 15 can be formed, can further improve the strength and stability of front frame.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention may be used also on the basis of the above description for those of ordinary skill in the art
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is all to belong to this hair
The obvious changes or variations that bright technical solution is extended out are still in the scope of protection of the present invention.
