Description

Technical Field

[0001] This invention belongs to the field of radar antenna technology, and relates to a double-layer film connection device for electrostatically formed thin-film reflective antennas, and also to a method for connecting double-layer films for electrostatically formed thin-film reflective antennas. Background Technology

[0002] Electrostatically formed thin-film reflector antennas are a type of high-precision reflector antenna. Their main structure consists of three parts: a base electrode structure, an electrode film, and a reflective film. Currently, the base structure is mostly a traditional cable-net antenna. The electrode film is divided into several electrode sheets and laid on the base cable-net surface to form the base electrode structure. The reflective film is made into the desired parabolic shape using a one-piece molding technique and suspended a distance above the base electrode structure. Applying a voltage between the electrode film and the reflective film generates electrostatic force, causing the reflective film surface to deform. By controlling the voltage, a high-precision reflective surface is formed.

[0003] The traditional method for fabricating the basic electrode film involves cutting electrode films of a designed size from a triangular electrode template, attaching the electrode films to the basic cable net, connecting electrode films in the same electrode area with conductive cloth, and separating different electrode areas with insulating tape strips and release paper, thus completing the laying of the basic electrode film on the front mesh of the antenna net.

[0004] Current bonding methods have several drawbacks. Since the electrode films are bonded after the antenna base cable net is erected, and the bonding is done in a suspended state, it's difficult to ensure uniform bonding between adjacent sides of two adjacent triangular electrode films. This results in an uneven surface and stress concentration. Firstly, the bonding process takes place within a cable net structure, which is highly inconvenient for manual operation. Secondly, the finished base electrode film is composed of multiple triangular planes, introducing fundamental errors in electrostatic forming thin film control theory. The spacing between the electrode film and the upper reflective film is inconsistent, and the local structure is not suitable for equivalent parallel-plate capacitors, leading to significant errors in subsequent electrostatic forming control. Furthermore, the lack of limiting measures for the electrode spacing means that if the reflective film loosens or is improperly controlled, it can easily come into contact with the electrode film. Summary of the Invention

[0005] The purpose of this invention is to provide a double-layer film connection device for electrostatically formed thin-film reflective antennas, which solves the problem in the prior art that the surface cannot be guaranteed to be flat after the adjacent edges of the two electrode films are pasted together.

[0006] Another object of the present invention is to provide a method for connecting two layers of an electrostatically formed thin-film reflector antenna.

[0007] One aspect of the present invention is a double-layer film connection device for an electrostatically formed thin-film reflective antenna, comprising multiple elongated main ribs evenly distributed around the center of the antenna, a columnar rib adjustment device mounted on the top of each main rib, an elongated rib plate mounted on the top of the rib adjustment device, a rope-like first cable segment connecting two adjacent rib adjustment devices, a rope-like second cable segment connecting two adjacent main ribs, a vertical cable connecting the first cable segment and the second cable segment, a columnar cable-film connection device passing through the connection point of the first cable segment and the vertical cable, and a suspension support frame provided at the top edge of the main rib.

[0008] The invention is further characterized in that: the rib adjustment device includes a screw, an adjusting bolt, a limiting post and a stop nut arranged in sequence; the top surface of the adjusting bolt has a threaded hole that matches the screw thread, the limiting post and the stop nut fix the adjusting bolt to the main rib, the limiting post is a hexagonal hollow stud, and the top side is provided with an upper cable through hole to connect the first cable segment;

[0009] The cable-membrane connection device includes a flexible connector, a buckle cover, a connecting block, and a metal tube connected in sequence; the flexible connector includes a patch, a limiting cable, and a stop ball arranged in sequence; the buckle cover has a buckle cover cable through hole at the top, the limiting cable passes through the buckle cover cable through hole, the diameter of the buckle cover cable through hole is 1.5 to 2 times the diameter of the limiting cable, and a notch is provided at the bottom of the buckle cover.

[0010] The connecting block includes a first cylindrical section, a second cylindrical section connected to a metal tube, and a boss end that engages with the notch in the slot. A central through hole is provided at the top of the connecting block.

[0011] The diameter of the stop ball is larger than the diameter of the buckle cable hole, but smaller than the center diameter of the boss end.

[0012] The first cylindrical section has a lateral cable-passing hole and a connecting block platform on its surface. The second cylindrical section has a through hole with an internally threaded section for connecting metal pipes. The diameter of the lateral cable-passing hole is 1.5 to 2 times the diameter of the first cable section and there is a certain gap between it and the connecting block platform.

[0013] The diameter of the first cylindrical section is 2 to 2.5 times the diameter of the cap.

[0014] The internal thread section passes through the center of the second cylindrical section along the axial direction, and the thread diameter is the same as the outer diameter of the metal tube. An external thread section is provided on the outside of the metal tube.

[0015] Another aspect of the present invention is a method for connecting two layers of an electrostatically formed thin-film reflective antenna, which is specifically implemented according to the following steps:

[0016] Step 1: The first cable segment passes horizontally into the lateral cable hole of the connecting block, and the vertical cable passes through the center hole at the bottom of the connecting block (202) and connects with the first cable segment. The connection point is located at the center of the connecting block, so that the first cable segment and the vertical cable form a "T" shape.

[0017] Step 2: Insert a metal tube below the connecting block, and insert the lower end of the vertical cable into the metal tube. The metal tube is threaded to the connecting block. Relying on the tension of the vertical cable, the connecting block and the metal tube are kept vertical as a whole, preventing the connecting block from deflecting around the first cable segment.

[0018] Step 3: Connect the second cable segment directly to the vertical cable, and connect it to the first cable segment to form a whole, thus forming a cable net;

[0019] Step 4: A vertical elongated hole is drilled on the main rib, through which the adjusting bolt passes. The adjusting bolt above the main rib is fixed with a limiting post, and the adjusting bolt below the main rib is fixed with a stop nut. The height of the top of the bolt is adjusted using the limiting post and the stop nut.

[0020] Step 5: Holes are made on the rib strip, and the hole positions correspond to the rib adjustment device positions. Screws (104) are connected to the top of the adjusting bolts through the holes on the rib strip. Multiple rib adjustment devices are placed on the main rib, and the position of the rib strip is adjusted by the height of the multiple adjusting bolts.

[0021] Step 6: Connect the first cable segment to the cable hole at the upper end of the limiting post, and connect the second cable segment to the cable hole at the lower end of the main rib. Then hang the cable net on.

[0022] Step 7: Install the electrode film on the upper surface of the rib strip and the connecting block platform. A circular hole is opened in the electrode film area. The diameter of the circular hole is larger than the diameter of the cover and smaller than the diameter of the first cylindrical section, so as to facilitate the electrode film to be pasted on the connecting block platform.

[0023] Step 8: The limiting cable passes through the buckle cover, and the stop ball is fixed to the lower end of the limiting cable to form a soft connector;

[0024] Step 9: The cover is snapped down through the protruding end of the connecting block and snapped into place. Multiple cable membrane connecting devices are placed on the first cable segment. The electrode membrane is pasted and connected to the multiple cable membrane connecting devices to realize the connection between the cable net and the electrode membrane.

[0025] Step 10: The outer edge of the reflective film is suspended on the support frame at the outer end of the main rib, keeping the reflective film at a certain distance above the electrode film. The patch of the cable-film connecting device is pasted on the back of the reflective film, so that the reflective film and the electrode film are aligned and installed.

[0026] The invention is further characterized in that: the rib adjustment device and the cable membrane connection device are installed when the antenna is fully deployed; when the first cable segment is in the shape of a cross, two through holes are opened radially in the lateral cable through hole of the connecting block; when it is in the shape of an asterisk, three through holes are opened, and the opening direction of the through holes is the same as the distribution of the first cable segment.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention can eliminate the need for cutting and splicing of electrode films, and use an integrally formed film to ensure the integrity and continuity of the film surface. The cable-film connection device of this invention can connect the cable net, the entire electrode film and the entire reflective film, eliminating the tedious and rough manual pasting operation and reducing the principle error of electrostatic forming film reflective antenna design.

[0029] 2. The present invention can achieve controllable membrane electrode spacing. The buckle height of the cable-membrane connection device limits the minimum membrane electrode spacing, and the length of the limiting cable limits the maximum membrane electrode spacing.

[0030] 3. The design of this invention can avoid the risk of membrane contact during electrostatic control. At the same time, the design of the limiting cable can ensure that the reflective film will unfold along with the electrode film during the antenna deployment process and will not detach from the electrode film.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0042] This invention provides a double-layer film connection device for an electrostatically formed thin-film reflector antenna, such as... Figure 1 As shown, it includes a rib adjustment device 1 and a cable-membrane connection device 2; the rib adjustment device 1 is installed on the main rib 3, the top of the rib adjustment device 1 is installed with a rib strip 4, the first cable segment 501 is hung on the top of the limiting post 102 of the rib adjustment device 1, and the second cable segment 503 is hung on the lower side of the main rib 3; the cable net 5 is installed at the same time as the cable-membrane connection device 2; the electrode film is laid on the rib strip 4 and the cable-membrane connection device 2; the outermost ring of the reflective film is suspended on the support frame at the end of the antenna main rib 3, and is connected to the cable-membrane connection device 2 using a flexible connector 24 at the position directly opposite to it, so that the cable net 5, the electrode film, and the reflective film are connected.

[0043] like Figure 2 , Figure 3 As shown, the rib adjustment device 1 includes a screw 104, an adjusting bolt 101, a limiting post 102, and a stop nut 103 arranged sequentially from top to bottom. The top surface of the adjusting bolt 101 has a threaded hole that matches the thread of the screw 104. The screw 104 fixes the rib 4. The limiting post 102 and the stop nut 103 fix the adjusting bolt 101 on the main rib 3. The limiting post 102 is a hexagonal hollow stud with an upper cable through hole on the side of the top end, which connects to the first cable segment 501.

[0044] like Figure 4 As shown, the cable membrane connection device 2 includes a cover 201, a connecting block 202, a metal tube 203, and a flexible connector 204; the flexible connector 204 is connected to the cover 201, and the cover 201 and the metal tube 203 are respectively installed at both ends of the connecting block 202;

[0045] The flexible connector 204 includes a stop ball 204-3, a limiting cable 204-2, and a patch 204-1. After the limiting cable 204-2 passes through the central through hole of the cover 201, the stop ball 204-3 and the patch 204-1 are respectively installed at both ends of the limiting cable 204-2. Preferably, the stop ball 204-3 can be a lightweight plastic ball or a hollow stainless steel ball shell, and the patch 204-1 can be a soft film patch.

[0046] The diameter of the stop ball 204-3 should be greater than the diameter of the central through hole of the cover 201 and smaller than the diameter of the central hole of the boss end 202-3 of the connecting block 202, so as to prevent the limiting cable 204-2 from detaching upward from the cover 201 and thus limit the maximum distance between the electrode film 6 and the reflective film 7.

[0047] like Figure 5 As shown, the cover 201 has a cover cable through hole 201-1 along the axial direction. The diameter of the hole is twice the diameter of the limiting cable 204-2 of the flexible connector 204. The lower half of the cover 201 has an inner notch 201-2. When the cover 201 is snapped down, the notch 201-2 corresponds to the boss end 202-3 of the connecting block 202. Usually, the width of the notch is greater than the outer diameter of the boss end 202-3, so that the cover 201 can lock the boss end 202-3. The cover 201 can be made of 6061 aluminum alloy.

[0048] like Figure 6 As shown, the connecting block 202 includes a first cylindrical section 202-1 fixed to the cover 201 and a second cylindrical section 202-2 connected to the metal tube 203; the connecting block 202 has a central through hole 202-4 in the axial direction, the first cylindrical section 202-1 has a lateral cable-passing hole 202-5, a connecting block platform 202-7 is formed on the upper surface of the first cylindrical section, the boss end 202-3 is locked and connected to the cover 201, the second cylindrical section 202-2 has an internal thread section 202-6 in the through hole, which is threaded to the metal tube 203, and the connecting block 202 can be made of 6061 aluminum alloy;

[0049] The lateral cable-passing hole 202-5 of the connecting block 202 has a diameter twice that of the first cable segment. The distance from the cable-passing hole 202-5 to the connecting block platform 202-7 is not less than 3.5 mm to avoid interference between the curved surface of the electrode film 6 and the first cable segment 501. Depending on the connection form of the cable net 5, the number of lateral cable-passing holes 202-5 can be increased, and the opening direction should be consistent with the orientation of the first cable segment 501.

[0050] The diameter of the first cylindrical section 202-1 of the connecting block 202 should be 2 to 2.5 times the diameter of the cover 201, so that the electrode film 6 has a good adhesion area on the connecting block platform 202-7;

[0051] The internal threaded hole 202-6 of the connecting block 202 passes through the center of the cylinder along the axial direction, and its threaded hole diameter is the same as the threaded outer diameter of the metal tube 203.

[0052] like Figure 7 As shown, the outer side of the upper end of the metal tube 203 is provided with an external thread section 203-1. The outer diameter of the thread is the same as the outer diameter of the inner thread hole of the second cylindrical section 202-2 of the connecting block 202, which facilitates the connection between the metal tube 203 and the connecting block 202.

[0053] This invention provides a connection method for a double-layer film connection device for an electrostatically formed thin-film reflective antenna, specifically implemented according to the following steps:

[0054] Step 1: The first cable segment 501 passes through the lateral cable hole 202-5 of the connecting block 202. Using a hook tool, hook out the middle part of the cable segment from the top groove of the connecting block 202, while both ends of the cable segment are still in the side hole. The vertical cable 502 passes through the center hole at the bottom of the connecting block 202 and exits from the top groove, and is fixed to the first cable segment 501. Pull back the vertical cable 502 segment so that the fixed point retracts to the center position of the connecting block 202. At this time, the first cable segment 501 and the vertical cable 502 form a "T" shape.

[0055] Step 2: Insert a metal tube 203 of a certain length below the connecting block 202. The lower end of the vertical cable 502 passes through the metal tube 203. The metal tube 203 is threadedly connected to the connecting block 202 to prevent the connecting block 202 from deflecting around the first cable segment 501. Relying on the tension of the vertical cable 502, the connecting block 202 and the metal tube 203 remain vertical as a whole.

[0056] Step 3: The second cable segment 503 is directly connected to the vertical cable 502 and connected to the first cable segment 501 to form a whole, forming a cable net structure 5.

[0057] Step 4: A vertical elongated hole is drilled in the main rib 3, through which the adjusting bolt 101 passes. The adjusting bolt 101 above the main rib 3 is fixed with a limiting post 102, and the adjusting bolt 101 below the main rib 3 is fixed with a stop nut 103. The limiting post 102 and the stop nut 103 can adjust the height of the bolt top. When tightening the limiting post 102, the top side hole of the limiting post 102 is oriented towards the first cable segment 501, and the stop nut 103 achieves a tightening effect.

[0058] Step 5: Holes are made on the rib strip 4, and the positions of the holes correspond to the positions of the rib adjustment devices 1 on the main rib 3. The rib strip 4 is fixed to the top of the adjusting bolt 101 by screws 104 to form the rib adjustment device 1. Multiple rib adjustment devices 1 are generally placed on the main rib 3 to assist in adjusting the rib strip 4 to approach the parabolic shape. Four rib adjustment devices 1 are evenly installed on the main rib 3. Four holes corresponding to the positions of the rib adjustment devices 1 are made on the rib strip 4 for screws 104 to fasten the rib strip 4. By adjusting the height of multiple adjusting bolts 101, the rib strip 4 can be adjusted to get as close as possible to the designed bending shape. Preferably, the rib strip 4 can be made of 65 manganese steel spring sheet and designed to be parabolic.

[0059] Step 6: The outer end of the first cable segment 501 is connected to the upper cable hole 102-1 of the limiting post 102, and the outer end of the second cable segment 503 is connected to the lower cable hole 301 of the main rib 3.

[0060] Step 7: The electrode film is installed on the upper surface of the rib strip 4 and the connecting block platform 202-7. A circular hole is opened at the electrode film in the area directly above the connecting block 202. The size of the circular hole is slightly larger than the diameter of the cover 201 and smaller than the diameter of the first cylindrical section 202-1 of the connecting block 202, so as to facilitate the electrode film to be pasted on the connecting block platform 202-7. The installation method can be adhesive.

[0061] Step 8: The limiting cable 204-2 passes through the buckle cover 201, the stop ball 204-3 is fixed at the lower end of the limiting cable 204-2, and the other end is connected to the patch 204-1 to form a flexible connector 204. The movement of the two ends of the flexible connector 204 is restricted respectively. Under normal working conditions, the limiting cable 204-2 is in a relaxed state.

[0062] Step 9: The cover 201 is snapped down into place by the slot and the protrusion 202-3 of the connecting block 202, forming the cable-membrane connection device 2, thus connecting the cable net 5 and the electrode membrane. Multiple cable-membrane connection devices 2 are generally placed on the first cable segment 501. Depending on the position of the first cable segment 501 connected to the main rib 3, the length of the cable segment is different, and the number of devices is also generally different. The radial distribution rings of the antenna are 4 rings. The number of cable-membrane connection devices placed on the cable segments from the outside to the inside are 3, 2, 1 and 0 respectively.

[0063] Step 10: The outer edge of the reflective film is connected to the support frame 302 at the outer end of the main rib 3. When suspended, the reflective film is kept at a certain distance above the electrode film. The top of the cable-film connecting device 2 is connected to the reflective film with a soft connection. The patch 204-1 is pasted on the reflective film area directly above the cable-film connecting device 2, so that the patch 204-1 is aligned with the electrode film. The double film is limited by the buckle 201 of the cable-film connecting device 2, so as to realize the connection between the cable net 5, the electrode film and the reflective film.

[0064] The installation of the rib adjustment device 1 and the cable membrane connection device 2 is carried out when the antenna main rib structure is fully deployed; the first cable segment 501 is a single cable, and the lateral cable-passing hole 202-5 of the connecting block 202 only needs to have one through hole opened radially, such as Figure 8 , Figure 9 As shown, if the first cable segment is in the shape of a cross or an asterisk, two and three through holes need to be opened radially in the lateral cable through hole 202-5 of the connecting block 202, respectively, and the direction of the through holes is the same as the distribution of the first cable segment.

[0065] The present invention provides a double-layer film connection device and method for electrostatically formed thin-film reflective antennas. The advantages are: it can eliminate the need for cutting and splicing of electrode films, use an integrally formed film to ensure the integrity and continuity of the film surface, and use the cable-film connection device of the present invention to connect the cable net, the entire electrode film and the entire reflective film, eliminating the tedious and rough manual pasting operation and reducing the principle error in the design of electrostatically formed thin-film reflective antennas.

The metal tube (203) is threadedly connected to the connecting block (202). Relying on the tension of the vertical cable (502), the connecting block (202) and the metal tube (203) are kept vertical as a whole, preventing the connecting block (202) from deflecting around the first cable segment (501). Step 3: Connect the second cable segment (503) directly to the vertical cable (502), and connect it with the first cable segment (501) to form a whole, forming a cable net (5); Step 4: A vertical long hole is drilled on the main rib (3), through which the adjusting bolt (101) passes. The adjusting bolt (101) above the main rib (3) is fixed with a limiting post (102), and the adjusting bolt (101) below the main rib (3) is fixed with a stop nut (103). The height of the top of the bolt is adjusted by the limiting post (102) and the stop nut (103). Step 5: Holes are made on the rib strip (4), and the positions of the holes correspond to the positions of the rib adjustment devices (1). Screws (104) are connected to the top of the adjusting bolts (101) through the holes on the rib strip (4). Multiple rib adjustment devices (1) are placed on the main rib (3). The position of the rib strip (4) is adjusted by the height of the multiple adjusting bolts (101). Step 6: The first cable segment (501) is connected to the upper cable hole (102-1) of the limiting post (102), and the second cable segment (503) is connected to the lower cable hole (301) of the main rib (3). The cable net (5) is then attached. Step 7: Install the electrode film on the upper surface of the rib strip (4) and the connecting block platform (202-7). A circular hole is opened in the electrode film area. The diameter of the circular hole is larger than the diameter of the cover (201) and smaller than the diameter of the first cylindrical section (202-1), so as to facilitate the electrode film to be pasted on the connecting block platform (202-7). Step 8: The limiting cable (204-2) passes through the buckle cover (201), and the stop ball (204-3) is fixed at the lower end of the limiting cable (204-2) to form a soft connector (204). Step 9: The cover (201) is fastened downwards by the boss end (202-3) of the connecting block (202) and fastened into place with the connecting block (202). Multiple cable membrane connecting devices are placed on the first cable segment (501). The electrode membrane is pasted and connected to the multiple cable membrane connecting devices to realize the connection between the cable net (5) and the electrode membrane. Step 10: The outer edge of the reflective film is suspended on the support frame (302) at the outer end of the main rib (3), keeping the reflective film at a certain distance above the electrode film. The patch (204-1) of the cable-film connection device (2) is pasted on the back of the reflective film, so that the reflective film and the electrode film are aligned and installed.

9. The method for connecting the double-layer film of an electrostatically formed thin-film reflector antenna according to claim 8, characterized in that, When installing the rib adjustment device (1) and the cable membrane connection device (2), the antenna is fully deployed; when the first cable segment is "+" shaped, two through holes are radially opened in the lateral cable through hole (202-5) of the connecting block (202), for " When the cable is shaped like the character "", three through holes are opened, and the direction of the through holes is the same as the distribution of the first cable segment.
