[0002] At present, flexible thin film antennas have been widely applied in various fields and have the advantages of light weight, flexibility and conformability. However, for antennas with a large area and a large number of units, there is a demand for new deployable types.

[0003] During the assembly of the whole machine, the antenna needs to be in a folded state and can be conveniently loaded on the surface of the whole machine. After reaching the working space, the antenna is deployed. The antenna is required to be deployable and retractable. Since the thin film antenna material is a copper-clad film material without carrier support, it does not have a certain supporting strength. Therefore, the existing thin film antenna is fixed and tensioned by a frame around the thin film antenna. Although the antenna has a flexible state in the working area, the supporting frame cannot be flexibly conformable, and the flexible state is still limited. SUMMARY

[0038] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0039] In conjunction with Figures 1 to 9 As shown, according to the first aspect of the embodiments of the present application, a flexible deployable thin film antenna support structure is provided, which comprises a first support part and a second support part, the first support part comprises a first elastic support assembly 11, the second support part comprises a second elastic support assembly 21, the first elastic support assembly 11 and the second elastic support assembly 21 are respectively connected with the thin film antenna 3, the first elastic support assembly 11 and the second elastic support assembly 21 are arranged at an angle, used to support and lock the thin film antenna 3.

[0040] By arranging the first support part and the second support part, the thin film antenna 3 can be supported. By arranging the first elastic support assembly 11 and the second elastic support assembly 21, and arranging the first elastic support assembly 11 and the second elastic support assembly 21 at an angle, cooperation is formed to effectively support and lock the thin film antenna 3, and more uniform support force is provided, which ensures that the thin film antenna 3 has good stability. Since the first elastic support assembly 11 and the second elastic support assembly 21 have elasticity, they can better cooperate with the flexible characteristics of the thin film antenna 3 through their own elasticity, reduce the limitation on the flexible state, make the antenna can more fully play its flexible advantage, improve the adaptability and reliability of the thin film antenna 3.

[0041] Among them, the flexible deployable thin film antenna support structure in the embodiment is applied to a large array antenna.

[0042] The first elastic support assembly 11 and the second elastic support assembly 21 are both elastic and can be elastically deformed and exert elastic force.

[0043] Specifically, based on the characteristics that the first elastic support assembly 11 and the second elastic support assembly 21 can be elastically deformed and exert elastic force, the elastic force can be used to support the film antenna 3, and the elastic deformation can be used to better cooperate with the flexibility of the film antenna 3, conform to the film antenna 3, and thus provide good support for the film antenna 3.

[0044] The first elastic support assembly 11 and the second elastic support assembly 21 are arranged at an angle, that is, cross arrangement, so that the first elastic support assembly 11 and the second elastic support assembly 21 can cooperate with each other, and thus provide good and stable support in a large range. By arranging the first elastic support assembly 11 and the second elastic support assembly 21 at an angle, opposite forces can be applied between them, so as to lock the relative positions of the first elastic support assembly 11 and the second elastic support assembly 21, keep the overall shape unchanged, and thus keep the shape of the film antenna 3 unchanged, that is, lock the film antenna 3.

[0045] One end of the first elastic support assembly 11 is connected to the first side of the film antenna 3, and the other end is connected to the second side of the film antenna 3. One end of the second elastic support assembly 21 is connected to the first side of the film antenna 3, and the other end is connected to the second side of the film antenna 3. When the film antenna 3 is locked, the first elastic support assembly 11 and the second elastic support assembly 21 are arranged at an angle.

[0046] By arranging the first elastic support assembly 11 and the second elastic support assembly 21 at an angle, support force can be provided to the film antenna 3 from different directions, so that the support is more stable and reliable, and the shape and structural stability of the film antenna 3 can be maintained. The support assembly arranged at both ends of the film antenna 3 can more evenly distribute stress, reduce local stress concentration, and prolong the service life of the film antenna 3.

[0047] The first side and the second side of the film antenna 3 are opposite sides. For example, the film antenna 3 is rectangular, the first side can be the left side of the film antenna 3, and the second side can be the right side of the film antenna 3. Of course, it can also be the upper side and the lower side. In this embodiment, the film antenna 3 is taken as a rectangle, the first side is one end of the length direction of the rectangle, and the second side is the other end of the length direction of the rectangle.

[0048] When the film antenna 3 is locked, the first elastic support assembly 11 and the second elastic support assembly 21 are arranged in a straight line.

[0049] Wherein, when locking the film antenna 3, the intersection point of the first elastic support assembly 11 and the second elastic support assembly 21 is located at the midpoint of the first elastic support assembly 11 and also at the midpoint of the second elastic support assembly 21.

[0050] Specifically, when locking the film antenna 3, the first elastic support assembly 11 and the second elastic support assembly 21 are mirror image arranged, the symmetry axis passes through the intersection point and is parallel to the short side of the rectangular film antenna 3.

[0051] Wherein, both ends of the first elastic support assembly 11 and both ends of the second elastic support assembly 21 are fixedly connected with the film antenna 3.

[0052] As shown in Figure 1 , the first elastic support assembly 11 includes a first elastic crank 111 and a first elastic connecting rod 112, and the first support part further includes a first rocker 12, the first elastic crank 111, the first elastic connecting rod 112 and the first rocker 12 are sequentially hinged, the first rocker 12 is connected with the film antenna 3, and the end of the first elastic crank 111 away from the first elastic connecting rod 112 is connected with the film antenna 3. When locking the film antenna 3, the first elastic crank 111 and the first elastic connecting rod 112 are in the same straight line.

[0053] Wherein, the first elastic crank 111, the first elastic connecting rod 112 and the first rocker 12 are sequentially hinged, that is, the first elastic crank 111 is hinged with the first elastic connecting rod 112, and the first elastic connecting rod 112 is hinged with the first rocker 12, forming a crank rocker mechanism. When locking the film antenna 3, the first elastic crank 111 and the first elastic connecting rod 112 are in the same straight line, at this time the crank rocker mechanism reaches the dead point position. At the dead point position, the transmission angle of the mechanism is zero, which can realize the locking of the crank rocker mechanism, and then the locking of the film antenna 3 can be realized, so as to keep it in a stable state. The locking mechanism at the dead point position can effectively resist the interference of external force to a certain extent, prevent the film antenna 3 from deforming or shifting due to external force, and improve the reliability and durability of the antenna. The stable locking state helps to improve the signal receiving and transmitting effect of the film antenna 3, reduce signal fluctuation and interference, and improve the working efficiency of the antenna.

[0054] Wherein, the first elastic crank 111, the first elastic connecting rod 112 and the first rocker 12 all extend along a straight line to form a strip structure.

[0055] The first elastic crank 111 is fixedly connected to the carrier at one end away from the first elastic connecting rod 112, forming an absolutely fixed hole position. The other end of the first elastic crank 111 is hingedly connected to the first end of the first elastic connecting rod 112. The first rocker 12 is fixedly connected to the carrier at one end away from the first elastic connecting rod 112, forming an absolutely fixed hole position. The other end of the first rocker 12 is hingedly connected to the second end of the first elastic connecting rod 112. That is, the hinged point of the first elastic crank 111 and the first elastic connecting rod 112 is a moving point, and the hinged point of the first rocker 12 and the first elastic connecting rod 112 is a moving point, which can be arbitrarily accommodated or fixed with the skin of the film antenna 3, and deformed with the skin.

[0056] In order to increase the stability during locking, the hinged point of the first elastic crank 111 and the first elastic connecting rod 112 can be reinforced by a flexible connecting member 5 such as a strap, to ensure that the first elastic crank 111 and the first elastic connecting rod 112 are in a locked state, avoiding unlocking.

[0057] As shown in Figure 1 The second elastic support assembly 21 includes a second elastic crank 211 and a second elastic connecting rod 212. The second support portion further includes a second rocker 22, which is hingedly connected in sequence to the second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22. The second rocker 22 is connected to the film antenna 3, and the second elastic crank 211 is connected to the film antenna 3 at one end away from the second elastic connecting rod 212. When the film antenna 3 is locked, the second elastic crank 211 and the second elastic connecting rod 212 are in the same straight line.

[0058] The second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22 are hingedly connected in sequence, i.e., the second elastic crank 211 is hingedly connected to the second elastic connecting rod 212, and the second elastic connecting rod 212 is hingedly connected to the second rocker 22, forming a crank rocker mechanism. When the film antenna 3 is locked, the second elastic crank 211 and the second elastic connecting rod 212 are in the same straight line, at which time the crank rocker mechanism reaches a dead point position. At the dead point position, the transmission angle of the mechanism is zero, which can achieve locking of the crank rocker mechanism, and further can achieve locking of the film antenna 3, keeping it in a stable state. The locking mechanism at the dead point position can effectively resist external interference to a certain extent, preventing the film antenna 3 from deforming or shifting due to external force, and improving the reliability and durability of the antenna. The stable locking state helps to improve the signal reception and transmission effect of the film antenna 3, reduces signal fluctuation and interference, and improves the working efficiency of the antenna.

[0059] The second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22 all extend in a straight line to form a strip-shaped structure.

[0060] The second elastic crank 211 is fixedly connected to the carrier at one end away from the second elastic connecting rod 212, forming an absolutely fixed hole position. The other end of the second elastic crank 211 is hingedly connected to the first end of the second elastic connecting rod 212. The second rocker 22 is fixedly connected to the carrier at one end away from the second elastic connecting rod 212, forming an absolutely fixed hole position. The other end of the second rocker 22 is hingedly connected to the second end of the second elastic connecting rod 212. That is, the hinged point of the second elastic crank 211 and the second elastic connecting rod 212 is a moving point, and the hinged point of the second rocker 22 and the second elastic connecting rod 212 is a moving point, which can be arbitrarily accommodated or fixed with the skin of the thin film antenna 3, and deformed with the skin.

[0061] In order to increase the stability during locking, the hinged point of the second elastic crank 211 and the second elastic connecting rod 212 can be reinforced by a flexible connecting piece 5 such as a strap, to ensure that the second elastic crank 211 and the second elastic connecting rod 212 are in a locked state, avoiding unlocking.

[0062] By mirroring the first support part and the second support part, the thin film antenna 3 is supported and locked by the elastic force of the first elastic support assembly 11 and the second elastic support assembly 21 in the axial direction. The support force of the first elastic support assembly 11 and the second elastic support assembly 21 on the thin film antenna 3 is more evenly distributed, thereby improving the stability of the entire support structure and better supporting and locking the thin film antenna 3. Moreover, the locking effect is improved. Specifically, the first elastic support assembly 11 and the second elastic support assembly 21 can provide more reliable locking force when locking the thin film antenna 3, ensuring that the thin film antenna 3 maintains a stable shape during operation.

[0063] The thin film antenna 3 has a rectangular structure, and mirroring can better adapt to the shape of the thin film antenna 3, providing support force from multiple directions, so that the thin film antenna 3 can be more closely attached to the support structure, improving the performance of the antenna.

[0064] The mirroring of the first support part and the second support part makes the support structure have better symmetry and superior mechanical properties, effectively dispersing external forces and reducing structural deformation.

[0065] As shown in Figures 2 to 5 The first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22 are spirally extended into a strip shape, capable of producing elastic deformation in the axial and radial directions.

[0066] The first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 are helically extended into a strip shape, and then a spring type structure is formed, so that the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 can be elastically deformed in each direction, have full flexibility in each direction, can greatly match the flexible characteristics of the thin film antenna 3, reduce the limitation on the flexible state, make the antenna more fully play its flexible advantage, and improve the adaptability and reliability of the thin film antenna 3.

[0067] In the embodiment, the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 are helically extended into a strip shape, and a cavity is formed in the middle, which also reduces the overall weight and meets the light weight requirement.

[0068] Specifically, since the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 are long in length, they need to have the characteristic of light weight, and in the embodiment, a special engineering plastic is selected as the manufacturing material, such as PEEK and PPS.

[0069] In the running process, the spring type structure formed is gradually compressed, and the compressible amount at the dead point position is 0 mm, which has been compressed to the extreme. The opposite elastic forces of the first elastic connecting rod 112 and the second elastic connecting rod 212 are F1 and F2 respectively. Since the first elastic connecting rod 112 and the second elastic connecting rod 212 need to keep F1=F2, referring to the elastic force F=kx (k: spring elastic coefficient, x: compressed length mm), according to the crank rocker mechanism design principle, the crank length < connecting rod. Therefore, the full compression length of the crank < the full compression length of the connecting rod. Under the guarantee of the crank rocker dead point mechanism design principle, referring to the following elastic coefficient k calculation formula, the shear elastic modulus is related to the material, and considering the force balance principle, the materials of the first elastic connecting rod 112 and the second elastic connecting rod 212 are unchanged. In order to match the opposite position state on both sides, the wire diameter and the center diameter cannot adopt different parameters, so the increase of the k value can only be realized by changing the effective number of turns n. According to the analysis of formula 1, the smaller the effective number of turns n, the larger the k value.

[0070]

[0071] In the formula, G: shear elastic modulus [MPa]. d: wire diameter [mm, in]. n: effective number of turns [total number of turns-2]. D: center diameter [mm, in]. k: spring coefficient [N / mm, lb / in].

[0072] Through the above formula, the compression amount at the dead point position is 0, and the opposite direction of the crank and the rocker in the formed crank and rocker mechanism generates an elastic force F equal to the state, so as to ensure the supportability of the overall structure.

[0073] As shown in Figures 2 to 5 The first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22 are wrapped with a glass fiber film 4, which can play a good reinforcing effect and ensure good strength of the whole.

[0074] As shown in Figures 2 to 5 The glass fiber film 4 is in multiple sections, and the multiple glass fiber films 4 are arranged along the axial direction of the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212, and the second rocker 22. The glass fiber films 4 adjacent in the axial direction are spaced apart by at least twice the pitch, and the length of each glass fiber film 4 in the axial direction is at least twice the pitch.

[0075] By arranging the glass fiber film 4, the strength of the spring structure in the relaxed state is low, and the large opposite force generated when entering the dead point position is buffered.

[0076] The wrapping position of the glass fiber film 4 is affected by the pitch length, and a specially designed glass fiber film 4 is wrapped around the outer diameter of the formed spring structure. The required support strength can be achieved by adjusting the wrapping thickness, and the thickness T is greater than or equal to 0.05 mm.

[0077] As a feasible example, when there is a reflection requirement, the glass fiber film 4 includes a base layer 41, a reinforcing layer 42, and a reflection layer 43 stacked in sequence.

[0078] The base layer 41 can select a corresponding material according to actual use requirements, for example, a polyimide film material can be selected. The reinforcing layer 42 uses glass fiber mesh material, and adjusts the size and distribution density of the glass fiber mesh according to the strength requirement. The base layer 41 uses a thin layer of glue solution, covers the reflection layer 43, and completes material compounding by vacuum hot pressing process. The reflection layer 43 generally uses a conductor or a semiconductor material. The conductor material uses a magnetron sputtering method to grow a thin layer of substrate on the base layer 41, and then uses chemical plating to increase the thickness of the plating layer to meet the reflection thickness requirement.

[0079] As another feasible example, when there is no reflection requirement, the glass fiber film 4 includes a base layer 41, a reinforcing layer 42, and a base layer 41 stacked in sequence.

[0080] The base layer 41 can be made of polyimide film material according to actual use requirements. The reinforcing layer 42 is made of glass fiber mesh material. According to the strength requirement, the size and distribution density of the glass fiber mesh are adjusted. The base layer 41 and the reinforcing layer 42 are combined by brushing a thin layer of glue, and then the vacuum hot pressing process is used to complete the material compounding after covering the reflecting layer 43.

[0081] The hot pressing load of the glass fiber film 4 on the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 can make the glass fiber film 4 tightly combined with these components, increase the adhesion between them, and thus improve the stability of the entire support structure.

[0082] As shown in Figure 6 , the outer peripheral wall of the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 is planar in the axial direction of itself, and the inner peripheral wall of the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 is arc-shaped in the axial direction of itself. The outer peripheral wall is planar, which can facilitate the glass fiber film 4 to be wrapped on the outer peripheral wall.

[0083] Wherein, in the respective axial direction, the outer peripheral wall of the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 extends along a straight line. Overall, the outer peripheral wall is approximately straight cylindrical.

[0084] Wherein, in the respective axial direction, the inner peripheral wall of the first elastic crank 111, the first elastic connecting rod 112, the first rocker 12, the second elastic crank 211, the second elastic connecting rod 212 and the second rocker 22 is arc-shaped, and the middle part of the arc is convex radially inward.

[0085] As shown in Figure 6 , the end of the first elastic crank 111 is radially inwardly retracted to form a first step structure 1111, the end of the first elastic connecting rod 112 is radially inwardly retracted to form a second step structure 1121, the first step structure 1111 and the second step structure 1121 are abutted and spliced, and the connecting piece 5 passes through and connects the first step structure 1111 and the second step structure 1121 in sequence.

[0086] The end of the second elastic crank 211 is radially inwardly retracted to form a third step structure, the end of the second elastic connecting rod 212 is radially inwardly retracted to form a fourth step structure, the third step structure and the fourth step structure are abutted and spliced, and the connecting piece 5 passes through and connects the third step structure and the fourth step structure in sequence.

[0087] The end of the first rocker arm 12 is radially recessed to form a fifth step structure. The first step structure 1111 and the fifth step structure abut and fit together. The connector 5 passes through and connects the first step structure 1111 and the fifth step structure in sequence.

[0088] The end of the second rocker arm 22 is radially recessed to form a sixth step structure. The second step structure 1121 and the sixth step structure abut and fit together. The connector 5 passes through and connects the second step structure 1121 and the sixth step structure in sequence.

[0089] By setting the first step structure 1111, the second step structure 1121, the third step structure, the fourth step structure, the fifth step structure, and the sixth step structure, rotational motion can be ensured at the connection point, while restricting the other five degrees of freedom.

[0090] Among them, the first step structure 1111, the second step structure 1121, the third step structure, the fourth step structure, the fifth step structure and the sixth step structure are all roughly semi-cylindrical structures.

[0092] Among them, the connector 5 is a hollow rivet. The hollow rivet method is used for fixing, which ensures that the connection has a certain amount of rotational movement and also ensures a certain degree of mobility in other directions, thus having a certain degree of flexible structure and meeting the requirements of lightweight.

[0093] The hollow riveting structure consists of two parts: a male head and a female head. During assembly, the female head is placed on top of the male head, ensuring full contact with the edge of the fixing node. After full contact, it needs to be pressed against the inner wall of the male head, applying a certain impact force. Because the male head annular wall is relatively thin, for example, 0.5mm, after applying a fixed amount of impact force, the area of ​​the male head annular ring above the female head deforms under the force, compressing and fixing it along the inner hole of the female head.
