[0046] The following combines Figures 1 to 19 to describe the modular antenna provided by the present invention.

[0047] It should be noted that in the embodiments of the present invention, the X direction, Y direction and Z direction specifically refer to Figure 1 the directions indicated by the arrows in the coordinate system shown in

[0048] Referring to Figures 1 to 4 as shown, the modular antenna provided by the embodiments of the present invention includes: a truss 100 and a plurality of antenna modules 200.

[0049] The truss 100 includes a truss body 110 and a plurality of antenna mounting units 120. The antenna mounting unit 120 includes a positioning mechanism 121 and a locking mechanism 122. The positioning mechanism 121 includes a positioning base 1211, and a positioning channel is formed in the positioning base 1211. The locking mechanism 122 includes a locking base 1221 and a locking assembly 1222. A locking channel is formed in the locking base 1221, and the locking assembly 1222 is arranged in the locking base 1221.

[0050] The antenna modules 200 correspond to the antenna mounting units 120 one by one. The antenna module 200 includes an antenna body 210, a positioning male head 220 and a locking male head 230. The positioning male head 220 and the locking male head 230 are both arranged on the antenna body 210.

[0051] In the working state, multiple antenna modules 200 are arranged on the truss body 110 through corresponding antenna mounting units 120. The positioning male head 220 is inserted and matched with the corresponding positioning channel, and the locking male head 230 is located in the corresponding locking channel and is locked and matched with the locking assembly 1222.

[0052] It should be noted that the "working state" in the embodiments of the present invention specifically refers to the state when the antenna module 200 is assembled on the truss 100.

[0053] See Figure 4 As shown, for the modular antenna provided by the present invention, during on-orbit assembly, first align the positioning male head 220 on the antenna module 200 with the positioning mechanism 121 on the corresponding antenna mounting unit 120, so that the positioning male head 220 on the antenna module 200 is inserted and matched with the positioning channel on the positioning base 1211. At the same time, align the locking male head 230 on the antenna module 200 with the locking mechanism 122 on the corresponding antenna mounting unit 120, insert the locking male head 230 on the antenna module 200 into the locking channel on the locking base 1221, and make the locking male head 230 be locked and matched with the locking assembly 1222. Its structure is simple and the assembly is convenient, which can realize the rapid positioning and locking of the antenna module 200, and solves the defects of the complex structure and cumbersome assembly process of the existing on-orbit assembled antennas.

[0054] Specifically, the modular antenna includes a truss 100 and an antenna module 200. Among them, the truss 100 is used to fix multiple antenna modules 200 in a set arrangement. There are multiple antenna mounting units 120 on the truss 100, and each antenna module 200 is connected to the corresponding antenna mounting unit 120 through a positioning and locking mechanism to achieve the stable assembly of each module. The antenna module 200 is a functional module of the modular antenna, which is used to realize the reception and transmission of wireless signals. Each antenna module 200 includes an antenna body 210, a positioning male head 220, and a locking male head 230, and can be quickly and stably installed on the truss 100 by cooperating with the positioning and locking mechanisms 122 of the antenna mounting unit 120 on the truss 100.

[0055] On the truss body 110, the number and arrangement of the antenna mounting units 120 can be set according to actual needs. For example, the antenna mounting units 120 can be arranged horizontally, obliquely, or in an array, etc., so that the assembled modular antenna can adapt to different coverage ranges and signal requirements. The number of antenna units can be adjusted according to the size of the communication range, the frequency of the antenna, the gain requirement, and the requirements of the working environment. The present invention does not limit this.

[0056] In each antenna mounting unit 120, the number of the positioning mechanism 121 and the locking mechanism 122 is at least one, which can be set according to actual requirements. For example, in application scenarios that require high precision (such as satellite communication, radar systems, etc.), a combination of multiple positioning mechanisms 121 and multiple locking mechanisms 122 can be adopted, which are respectively responsible for fine adjustment and strong fixation to ensure the stability and precise docking of the antenna module 200. In some occasions with simple structures or lower load-bearing requirements, a single positioning mechanism 121 and locking mechanism are sufficient to meet the requirements and ensure the basic functions and stability of the antenna.

[0057] When the male positioning head 220 cooperates with the corresponding positioning mechanism 121, the male positioning head 220 can be directly inserted into the positioning channel formed in the positioning base 1211. This insertion method ensures that the antenna module 200 can be quickly and accurately positioned during the assembly process through the precise cooperation between the male positioning head 220 and the positioning base 1211, and limits and fixes the antenna module 200 in the X and Y directions. When the male locking head 230 cooperates with the corresponding locking mechanism 122, the male locking head 230 is inserted into the locking channel formed in the locking base 1221, so that the male locking head 230 is locked and cooperated with the locking component 1222 in the locking channel, which can limit and fix the antenna module 200 in the Z direction. That is, under the combined action of the positioning mechanism 121 and the locking mechanism 122, the antenna module 200 can be quickly and simply assembled on the truss 100, and after the assembly is completed, it can realize the limiting and fixing functions in the X, Y, and Z directions, with strong stability.

[0058] See Figures 5 to 7 As shown, the positioning mechanism 121 includes a positioning base 1211. A positioning channel is provided in the positioning base 1211, and a male positioning head 220 that cooperates with the positioning channel is provided on the antenna body 210. The positioning base 1211 can adopt various forms in the prior art. For example, the positioning base 1211 is directly machined on the truss body 110, and the positioning channel is machined on the positioning base 1211, so that the positioning base 1211 is integrally provided with the truss body 110; alternatively, the positioning base 1211 can be used as an independent component and fixed to the truss body 110 through threaded fixing parts (such as screws). The male positioning head 220 can also adopt various forms known in the prior art, such as a cylindrical pin, a polygonal pin, etc.

[0059] As an example, in this embodiment, the male positioning head 220 is a cylindrical pin, and a tapered guiding portion is provided at its end. The positioning base 1211 is an independent component and is fixed to the truss body 110 through threaded fixing parts. The positioning channel is arranged along the axial direction of the positioning base 1211. Similarly, a tapered surface is provided at the inlet end of the positioning channel to reduce the docking difficulty between the male positioning head 220 and the positioning channel.

[0060] To prevent the positioning male head 220 from exceeding the limit position during assembly, a limiting plate is provided at the tail end of the positioning male head 220 for abutting against the end face of the positioning base 1211 to achieve limiting.

[0061] See Figures 8 to 15 As shown, the locking mechanism 122 includes a locking base 1221 and a locking component 1222. A locking channel is formed in the locking base 1221. The locking component 1222 is disposed in the locking base 1221. A locking male head 230 that matches the locking channel and can be locked and cooperated with the locking component 1222 is provided on the antenna body 210. Similarly, the locking base 1221 can adopt various forms in the prior art. For example, the locking base 1221 is directly machined on the truss body 110, and the locking channel is machined on the locking base 1221, so that the locking base 1221 is integrally provided with the truss body 110; the locking base 1221 can also be used as an independent component and fixed to the truss body 110 through threaded fixing members (such as screws). The locking component 1222 and the locking male head 230 can also adopt various forms in the prior art, such as a spring locking component, a snap-type locking component, etc. Among them, the spring locking component realizes automatic locking by compressing the spring. When the locking male head 230 is inserted, the locking member 12221 drives the spring to be compressed. When the male head is completely inserted, the spring returns to its original state and presses the locking member 12221 to lock the locking male head 230. The snap-type locking component utilizes the snap or card slot structure between the locking male head 230 and the locking channel to automatically lock when inserted, forming a firm connection.

[0062] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a plurality of antenna mounting units 120 are adjacent to each other along the X direction on the truss body 110. In the working state, a plurality of antenna modules 200 are adjacent to each other along the X direction on the truss body 110, and the adjacent side walls of the adjacent antenna bodies 210 are attached to each other.

[0063] By arranging a plurality of antenna modules 200 adjacent to each other on the truss body 110 and making the adjacent side walls of the adjacent antenna bodies 210 attached to each other, the space utilization rate can be optimized and the overall volume of the device can be reduced, and each antenna module 200 can be mutually limited, improving the stability of the modular antenna.

[0064] See Figures 1 to 4 As shown, according to some embodiments of the present invention, the antenna mounting unit 120 includes two positioning mechanisms 121 and two locking mechanisms 122. One positioning mechanism 121 and one locking mechanism 122 are spaced apart and disposed on the first side of the truss body 110, and the other positioning mechanism 121 and the other locking mechanism 122 are spaced apart and disposed on the second side of the truss body 110 opposite thereto.

[0065] By separately arranging two positioning mechanisms 121 and two locking mechanisms 122 of the antenna mounting unit 120 at the first side and the second side of the truss body 110 respectively, the stability of the fixed antenna module 200 can be effectively improved.

[0066] Specifically, the two positioning mechanisms 121 and the two locking mechanisms 122 are arranged in a rectangular array, and both the two positioning mechanisms 121 and the two locking mechanisms 122 are located on the diagonal line, enabling the antenna module 200 to achieve a more uniform force distribution.

[0067] Specifically, after the antenna module 200 is fixed to the truss body 110, the two positioning mechanisms 121 arranged along the diagonal line can respectively limit and fix the two sides of the antenna module 200 in the X direction and the Y direction. At the same time, the two locking mechanisms 122 arranged along the diagonal line can respectively limit and fix the two sides of the antenna module 200 in the Z direction. The two positioning mechanisms 121 and the two locking mechanisms 122 avoid the problem of local force concentration through the diagonal layout, and significantly improve the stability of the fixed antenna module 200.

[0068] See Figure 8 As shown, according to some embodiments of the present invention, the antenna mounting unit 120 further includes an adjusting mechanism 123. The adjusting mechanism 123 includes a threaded adjusting member 1231. The threaded adjusting member 1231 is in threaded cooperation with the truss body 110 along the Z direction. In the working state, the ends of the threaded adjusting member 1231 abut against the bottom of the antenna body 210.

[0069] By providing the adjusting mechanism 123, the position of each antenna module 200 in the Z direction after assembly can be finely adjusted, enabling each antenna module 200 to maintain a set flatness, achieving precise control of the positions of the respective antenna modules 200, and avoiding signal unevenness or system performance degradation caused by height differences between modules. Solve the problem of poor flatness of each antenna module 200 due to precision reasons when the locking male head 230 is engaged with the locking mechanism 122.

[0070] Specifically, during adjustment, by rotating the threaded adjusting member 1231 to change the position of the end of the threaded adjusting member 1231, the height of the corresponding antenna module 200 in the Z direction can be finely adjusted.

[0071] See Figure 8 As shown, according to some embodiments of the present invention, the adjusting mechanism 123 further includes an elastic support member 1232. The elastic support member 1232 is arranged along the Z direction on the truss body 110. In the working state, the ends of the elastic support member 1232 abut against the bottom of the antenna body 210.

[0072] By setting the elastic support member 1232, additional elastic support can be provided to apply a pressing force to the antenna module 200, further enhancing the stability of the antenna module 200 when assembled to the truss body 110.

[0073] Preferably, the elastic support member 1232 is a spring. Of course, in some embodiments, elastic support members 1232 such as elastic pads can also be used, and no limitation is made thereto.

[0074] See Figures 8 to 15 As shown, according to some embodiments of the present invention, the locking mechanism 122 includes a plurality of locking components 1222, and the plurality of locking components 1222 are circumferentially spaced and arranged in the locking base 1221.

[0075] By circumferentially spacing the plurality of locking components 1222 in the locking base 1221, the locking mechanism 122 can evenly distribute the fixing force applied to the antenna module 200. After the antenna module 200 is installed, the locking male head 230 can cooperate with the plurality of locking components 1222 to achieve firm locking, preventing uneven fixing or deformation of the antenna module 200 caused by excessive force on any side.

[0076] Specifically, by working together, the plurality of locking components 1222 can provide a more uniform and stable locking effect, making the connection between the antenna module 200 and the truss body 110 more stable, effectively reducing the problem of uneven local force during the locking process, and avoiding the risk of loosening or displacement that may be brought by a single locking point.

[0077] As an example, the locking mechanism 122 in this embodiment includes three locking components 1222, and the three locking components 1222 are evenly and circumferentially spaced and arranged in the locking base 1221. After the locking male head 230 is inserted into the locking channel, it can be locked and cooperate with the three locking components 1222 at the same time to achieve firm locking of the antenna module 200.

[0078] See Figures 8 to 15 As shown, according to some embodiments of the present invention, the locking component 1222 includes a locking member 12221 and an elastic reset member 12222. The locking member 12221 is slidably matched with the locking base 1221 in the radial direction. The elastic reset member 12222 is arranged in the locking base 1221 in the radial direction. One end of the elastic reset member 12222 is connected to the locking base 1221, and the other end of the elastic reset member 12222 is connected to the locking member 12221; the locking member 12221 includes a locking portion, and a locking groove 231 is circumferentially provided on the outer wall of the locking male head 230. In the working state, the locking portion is located in the locking groove 231 to axially limit the locking male head 230.

[0079] By setting the locking component 1222 to include a locking member 12221 and an elastic reset member 12222, automatic locking can be achieved when the male locking head 230 is inserted into the locking channel, with a simple mechanism and easy assembly.

[0080] Preferably, in this embodiment, the elastic reset member 12222 is a reset spring. Of course, in some embodiments, the elastic reset member 12222 can also be an elastic reset pad or the like, and there is no limitation in this regard.

[0081] Similarly, to prevent the male locking head 230 from exceeding the limit position during assembly, a limiting plate is provided at the tail end of the male locking head 230 for abutting against the end face of the locking base 1221 to achieve limiting.

[0082] See Figures 16 to 18 As shown, specifically, when the male locking head 230 is inserted into the locking channel, its end applies a radial force to the locking portion of the locking member 12221, causing it to move in the radially outward direction and applying a pressing force to the elastic reset member 12222. When the male locking head 230 continues to move downward and the locking groove 231 reaches the position of the locking portion, under the action of the elastic reset member 12222, the locking portion of the locking member 12221 enters the locking groove 231 to achieve the cooperation between the male locking head 230 and the locking component 1222.

[0083] See Figure 10 and Figure 15 As shown, according to some embodiments of the present invention, a first locking guiding inclined surface is formed on the inner side of the locking portion, and a second locking guiding inclined surface is formed circumferentially at the end of the male locking head 230 to drive the locking member 12221 to move in the radially outward direction when the second locking guiding inclined surface abuts against the first locking guiding inclined surface.

[0084] By providing a first locking guiding inclined surface on the inner side of the locking portion and a second locking guiding inclined surface circumferentially at the end of the male locking head 230, when the male locking head 230 is inserted, the first locking guiding inclined surface at its end can cooperate with the second locking guiding inclined surface to apply a radially outward force to the locking member 12221, pushing the locking member 12221 to move radially outward, so that the locking groove 231 on the male locking head 230 can smoothly cooperate with the locking portion.

[0085] See Figure 9 As shown, according to some embodiments of the present invention, the locking member 12221 further includes an unlocking portion, the unlocking portion is connected to the locking portion, a first unlocking guiding inclined surface is provided on the inner side of the unlocking portion, and an unlocking channel is further formed in the locking base 1221; the locking mechanism 122 further includes an unlocking member, and a second unlocking guiding inclined surface is provided circumferentially at the end of the unlocking member to drive the locking member 12221 to move in the radially outward direction when the second unlocking guiding inclined surface abuts against the first unlocking guiding inclined surface.

[0086] By providing an unlocking part and an unlocking member, and configuring corresponding first and second unlocking guiding inclined surfaces, the locking mechanism 122 can achieve a simple unlocking operation when needed. When the antenna module 200 fails and needs to be replaced or repaired, the locking male head 230 and the locking member 12221 can be unlocked by the unlocking member, so as to remove the antenna module 200 from the truss body 110.

[0087] Specifically, referring to Figure 19 As shown, when unlocking, the unlocking member extends into the locking base 1221 through the unlocking channel. After reaching a certain position, the second unlocking guiding inclined surface at the end of the unlocking member cooperates with the first unlocking guiding inclined surface inside the unlocking part, applying a radially outward acting force to the unlocking member, so that the locking part disengages from the locking groove 231 and the locking is released.

[0088] Referring to Figures 8 to 15 As shown, according to some embodiments of the present invention, the locking base 1221 includes a detachably connected locking base body 12211, a locking base cover 12212, an adjusting gasket 12213, an adapter 12214 and an end cap 12215. The locking base body 12211, the locking base cover 12212, the adjusting gasket 12213 and the adapter 12214 are arranged coaxially in sequence, the end cap 12215 is connected to both the locking base body 12211 and the locking base cover 12212, and one end of the elastic reset member 12222 is connected to the end cap 12215.

[0089] By configuring the locking base 1221 to include a detachably connected locking base body 12211, a locking base cover 12212, an adjusting gasket 12213, an adapter 12214 and an end cap 12215, the adjustability, modular design and easy maintenance functions of the locking mechanism 122 can be achieved.

[0090] Specifically, the locking base body 12211, the locking base cover 12212, the adjusting gasket 12213 and the adapter 12214 are arranged coaxially in sequence, providing a precisely docking structure to ensure that all parts can be closely fitted during installation, avoiding loosening or failure. The adjusting gasket 12213 can adjust the distance between the adapter 12214 and the locking base cover 12212, eliminating the problem that the locking male head 230 and the locking member 12221 cannot be effectively locked and fitted due to machining errors. For example, when the locking male head 230 and the locking member 12221 are fitted, there is still a gap at the fitting position, resulting in unstable locking of the antenna module 200 and easy shaking. At this time, a thicker adjusting gasket 12213 can be used.

[0091] The assembly and disassembly processes of the modular antenna provided by the present invention will be described below. Referring to Figures 1 to 4and Figures 16 to 19 as shown

[0092] During the assembly process of the antenna module 200, an on-orbit robot is used to operate the antenna module 200 close to the truss 100, so that the positioning male head 220 and the locking male head 230 at the bottom of the antenna module 200 are respectively aligned with the positioning mechanism 121 and the locking mechanism 122 on the corresponding antenna mounting unit 120.

[0093] Drive the antenna module 200 to move along the Z direction towards the truss 100. After reaching the set position, the second locking guiding slope at the end of the locking male head 230 cooperates with the first locking guiding slope inside the locking part, applying a radially outward force to the locking piece 12221, pushing the locking piece 12221 to move radially outward and compress the return spring, so that the locking groove 231 on the locking male head 230 cooperates with the locking part. Thus, the preliminary fixation of the antenna module 200 is completed.

[0094] After installing each antenna module 200 in sequence, check the flatness of each antenna module 200. When the flatness of the antenna module 200 does not meet the set requirements, it can be adjusted through the threaded adjusting part 1231 until the set requirements are met.

[0095] When the antenna module 200 fails and needs to be repaired or replaced, the corresponding antenna module 200 needs to be separated from the truss 100. The separation process is as follows: The on-orbit robot operates the unlocking piece to enter the locking base 1221 through the unlocking channel. After reaching a certain position, the second unlocking guiding slope at the end of the unlocking piece cooperates with the first unlocking guiding slope inside the unlocking part, applying a radially outward force to the unlocking piece, so that the locking part is disengaged from the locking groove 231, releasing the lock. At this time, the faulty antenna module 200 can move away from the truss 100 under the operation of the on-orbit robot until the two are separated.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
