Technical Field

[0001] The invention relates to the technical field of antenna module disassembly and assembly, and in particular to a hand-pull fixer for quickly disassembling and assembling an antenna module and a disassembly and assembly method thereof. Background Art

[0002] As the accuracy and power requirements in the field of radio communications and detection become increasingly higher, phased array antenna technology has been developed, which has greatly improved the detection accuracy and power carrying capacity of microwave communications, and also put forward higher requirements for the structural layout of phased array antennas.

[0003] Due to the space limitation of the antenna installation platform, higher requirements are placed on the overall structural compactness and integration of the phased array antenna. The high degree of integration of the phased array antenna as a whole will further compress the space available for the installation and removal of the antenna module;

[0004] On the other hand, the high-power usage of phased array antennas leads to a significant reduction in the mean trouble-free service time of components; therefore, during the life cycle of phased array antennas, the core components of phased array antennas are required to be able to be quickly replaced, installed and maintained to maintain the continuity of the working state of the phased array antenna.

[0005] Therefore, in view of the above problems, it is necessary to provide a new disassembly and assembly tool to achieve rapid disassembly, replacement, installation and maintenance of the antenna module in a limited space. Summary of the invention

[0013] Furthermore, three balls are circumferentially arranged on the fixing column. When the auxiliary extraction rod is matched with the auxiliary extraction hole, the annular groove is aligned with the balls.

[0014] Furthermore, the transmission assembly is a lever mechanism.

[0015] Furthermore, when the locking button pushes one end of the lever mechanism to move, the other end of the lever mechanism can push the cone sleeve to move downward.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] Example 1

[0037] In a specific embodiment of the present invention, a hand-pull fixture for quickly disassembling and assembling an antenna module is provided; Figure 1 , Figure 2 , Figure 3 As shown, the hand-pull fixture includes: a locking handle 4 and an auxiliary pull rod 24; wherein the auxiliary pull rod 24 is fixedly arranged on the upper surface of the disassembled component (antenna module 2); the locking handle 4 can be locked and connected with the auxiliary pull rod 24 or unlocked and separated.

[0038] The locking handle 4 includes: a locking assembly, a transmission assembly and a locking button 413 .

[0039] Specifically, pressing or releasing the locking button 413 can drive the locking assembly to lock or unlock the auxiliary extraction rod 24; the transmission assembly is arranged between the locking assembly and the locking button 413, and is used to transmit the power provided by the locking button 413 to the locking assembly.

[0040] Specifically, the auxiliary extraction rod 24 is integrally formed with the antenna module 2; or, a threaded section is provided at the lower end of the auxiliary extraction rod 24, and the auxiliary extraction rod 24 is screwed to the antenna module 2. The present invention provides an auxiliary extraction rod 24 and is fixedly connected to the antenna module 2. The locking assembly locks the auxiliary extraction rod 24, so that the locking handle 4 can lock the antenna module 2, and then the antenna module 2 can be disassembled.

[0041] Specifically, Figure 3 , Figure 6 As shown, an auxiliary extraction rod 24 is provided on the upper surface of the antenna module 2 , and the locking assembly of the locking handle 4 is connected to or disconnected from the auxiliary extraction rod 24 , and then the antenna module 2 is disassembled and installed through the locking handle 4 .

[0042] I) Locking components:

[0043] like Figure 3 , Figure 4As shown, the locking assembly includes: a tapered sleeve 403, a ball 402 and a fixed column 404; the lower end of the fixed column 404 is provided with an auxiliary pulling hole that can cooperate with the auxiliary pulling rod 24, and the auxiliary pulling rod 24 can be inserted into the auxiliary pulling hole; the ball 402 is floatingly installed in the fixed column 404, and one side of the ball 402 protrudes from the outer surface of the fixed column 404, and the other side protrudes from the inner wall surface of the auxiliary pulling hole; the upper end of the auxiliary pulling rod 24 is provided with an annular groove 242, and the annular groove 242 is aligned with the ball 402 when the auxiliary pulling rod 24 is inserted into the auxiliary pulling hole; the tapered sleeve 403 is slidably sleeved on the outside of the fixed column 404, and the lower end of the tapered sleeve 403 is provided with a tapered hole, and when the tapered sleeve 403 moves downward, the ball 402 can be pressed into the annular groove 242 of the auxiliary pulling rod 24 through the tapered hole.

[0044] Furthermore, if Figure 3 , Figure 4 As shown, the aperture of the tapered hole gradually decreases from bottom to top. When the tapered sleeve 403 moves downward, the small end of the tapered hole gradually approaches the ball 402. The inner wall surface of the tapered hole squeezes the ball 402, and the ball 402 moves toward the axial direction of the fixed column 404, and can then be inserted into the annular groove 242 of the auxiliary ejection rod 24; when the ball 402 is inserted into the annular groove 242, the locking assembly is connected to the auxiliary ejection rod 24.

[0045] Then, the antenna module 2 can be removed from the antenna frame 1 by pulling the locking handle 4 upward.

[0046] Furthermore, if Figure 3 , Figure 4 As shown, the locking assembly further includes a pressing sleeve 406 .

[0047] The pressing sleeve 406 is slidably sleeved on the outside of the fixed column 404, and can slide along the fixed column 404 under the drive of the transmission assembly. Specifically, the pressing sleeve 406 is arranged above the cone sleeve 403, and is fixedly connected to the upper end of the cone sleeve 403.

[0048] Specifically, the lower end of the pressing sleeve 406 is provided with an external thread, the upper end of the tapered sleeve 403 is provided with a threaded hole, and the pressing sleeve 406 and the tapered sleeve 403 are screwed together through threads.

[0049] Furthermore, if Figure 2 , Figure 3 , Figure 4 As shown, a spring positioning convex ring 441 is arranged on the outside of the fixed column 404, and a spring 405 is arranged between the spring positioning convex ring 441 and the pressing sleeve 406; the spring 405 is sleeved on the outside of the fixed column 404 and is located in the threaded hole at the upper end of the tapered sleeve 403; the upper end of the spring 405 abuts against the lower end surface of the pressing sleeve 406, and the lower end of the spring 405 abuts against the upper end surface of the spring positioning convex ring 441.

[0050] When the pressing sleeve 406 and the cone sleeve 403 move downward, the spring 405 is compressed; when the locking button 413 is released, the pressing sleeve 406 and the cone sleeve 403 can be reset under the elastic force of the spring 405, thereby relieving the pressure on the ball 402, and the ball 402 can be moved out of the annular groove 242, thereby unlocking the auxiliary extraction rod 24.

[0051] Furthermore, the locking assembly also includes: a connecting pin 407 .

[0052] like Figure 2 , Figure 4 As shown, the upper part of the fixing column 404 is provided with a U-shaped hole 442 extending along its own axial direction, and the connecting pin 407 is perpendicular to the axial direction of the fixing column 404 and is slidably installed in the U-shaped hole 442 on the upper part of the fixing column 404; further, the connecting pin 407 passes through the U-shaped hole 442 and is fixedly connected with the pressing sleeve 406; specifically, a pin hole is provided on the pressing sleeve 406, and the connecting pin 407 is fixedly installed in the pin hole of the pressing sleeve 406 by bonding, welding or interference fit.

[0053] When the locking button 413 is pressed, the locking button 413 can drive the connecting pin 407 to slide downward along the U-shaped hole 442 through the transmission assembly, and then the connecting pin 407 can drive the cone sleeve 403 to move downward through the pressing sleeve 406; when the locking button 413 is released, the elastic force of the spring 405 pushes the pressing sleeve 406 to move upward, and then drives the connecting pin 407 to slide upward along the U-shaped hole 442, and the cone sleeve 403 also moves upward.

[0054] Specifically, when the conical sleeve 403 moves downward, the ball 402 can be pressed into the annular groove 242 of the auxiliary extraction rod 24 for engagement, and the locking assembly is connected to the auxiliary extraction rod 24 as a whole, so that the locking handle 4 and the antenna module 2 can move synchronously; when the conical sleeve 403 moves upward, the limiting effect on the ball 402 can be released, and the ball 402 can be moved out of the annular groove 242 of the auxiliary extraction rod 24, so that the locking handle 4 can be separated from the antenna module 2.

[0055] Furthermore, the fixing column 404 is fixed to the housing as a whole. Specifically, the fixing column 404 is fixedly connected to the upper cover 414 by fastening screws 415 .

[0056] Specifically, the extraction-assisting hole at the lower end of the fixing column 404 is a cylindrical hole, such as Figure 5 shown.

[0057] Furthermore, three balls 402 are circumferentially arranged on the fixing column 404. Figure 5 Specifically, three ball mounting holes are circumferentially arranged on the side of the fixing column 404, and the balls 402 are arranged in the ball mounting holes, and the balls 402 can float left and right in the ball mounting holes.

[0058] Specifically, the ball mounting hole is a conical hole, and the diameter of one end of the conical hole connected to the extraction-assisting hole is smaller than the diameter of the ball 402. The ball 402 is limited on one side by the conical sleeve 403, and on the other side by the small end of the conical hole. Figure 5 shown.

[0059] In a specific embodiment of the present invention, in order to ensure the locking effect of the ball 402 on the auxiliary ejection rod 24, a limiting protrusion ring 241 is provided at the lower part of the auxiliary ejection rod 24. When the bottom end of the outer shell 408 of the locking handle 4 contacts the limiting protrusion ring 241 of the auxiliary ejection rod 24, the annular groove 242 can be exactly aligned with the ball 402.

[0060] Furthermore, a retaining ring 401 is fixedly arranged inside the housing 408, and the retaining ring 401 is located below the cone sleeve 403. When the cone sleeve 403 moves downward due to an external force, it can contact the retaining ring 401. In the present invention, the depth of the auxiliary extraction rod 24 extending into the auxiliary extraction hole is controlled by the limiting convex ring 241, and the displacement of the cone sleeve 403 is limited by the retaining ring 401.

[0061] In a specific embodiment of the present invention, the locking handle 4 further includes: a housing 408 and an upper cover 414; the locking assembly and the transmission assembly are both arranged in a cavity surrounded by the housing 408 and the upper cover 414. Specifically, the upper cover 414 and the housing 408 are fixed as a whole by bonding, welding or bolting.

[0062] II) Transmission components:

[0063] like Figure 2 As shown, the transmission assembly is a lever mechanism; one end of the lever mechanism is pushed to move by the locking button 413, and then the pressing sleeve 406 can be pushed downward by the other end of the lever mechanism.

[0064] Specifically, Figure 2 , Figure 3 , Figure 4 As shown, the transmission assembly includes: a transmission lever 410 and a button pressing block 412; specifically, the transmission lever 410 is rotatably installed inside the housing 408 through a rotating shaft 411; the button pressing block 412 is fixedly set at one end of the transmission lever 410, and a convex portion is set at the lower end of the button pressing block 412, and rolling contact is made with the upper surface of the locking button 413 through the convex portion.

[0065] When the locking button 413 is pressed upward, the convex part rolls relative to the upper end surface of the locking button 413, and the transmission lever 410 rotates around the rotating shaft 411, and the other end of the transmission lever 410 presses down the connecting pin 407 and the pressing sleeve 406. When the locking button 413 is released, the pressing sleeve 406 moves upward under the elastic force of the spring 405, and then drives the transmission lever 410 to rotate in the opposite direction through the connecting pin 407, and the transmission lever 410 presses down the locking button 413 through the button pressing block 412, so that the locking button 413 is reset, and the locking button 413 is reset and protrudes out of the housing 408.

[0066] Specifically, a button locking button 413 is provided on the shell 408 and passes through the shell 408 and can slide relative to the shell 408; a limiting portion is provided at the upper end of the locking button 413 to prevent the locking button 413 from detaching from the shell 408; the locking button 413 is provided at the lower end of the middle part of the shell 408 and protrudes from the shell 408.

[0067] Specifically, both ends of the rotating shaft 411 are rotatably connected to the housing 408 via bearings. Alternatively, the rotating shaft 411 is fixedly connected to the housing 408, and the transmission lever 410 is sleeved and installed outside the rotating shaft 411 and can rotate relatively.

[0068] Furthermore, the transmission assembly further includes: a pressing block 409; a button pressing block 412 is fixedly installed at one end of the transmission lever 410, and a pressing block 409 is fixedly installed at the other end, and the pressing block 409 is in sliding contact with the connecting pin 407. When the locking button 413 is pressed to rotate the transmission lever 410, the pressing block 409 can be driven to move downward, and then the connecting pin 407 is pressed downward to move downward along the U-shaped hole 442 of the fixing column 404. When the pressing block 409 presses the connecting pin 407, the two slide relative to each other.

[0069] Furthermore, in the present invention, the locking handle 4 is an inverted U-shaped structure; two sets of locking components and transmission components are symmetrically arranged in the housing 408. Both sets of locking components and transmission components are driven by the locking button 413, thereby locking the two auxiliary extraction rods 24 on the upper surface of the antenna module 2.

[0070] In the present invention, the locking handle 4 can match any antenna module 2, and after being locked by connecting with the auxiliary pull-out rod 24, the antenna module 2 can be lifted and removed from the antenna frame 1. Figure 2 , Figure 6 shown.

[0071] Specifically, the locking button 413 is pressed and the pressing sleeve 406 is pushed downward by the lever mechanism. When the pressing sleeve 406 moves downward, the conical sleeve 403 can be driven downward, and then the conical sleeve 403 can press the ball 402 into the annular groove 242 of the compression auxiliary extraction rod 24, thereby locking the locking handle 4 and the antenna module 2. When the entire locking handle 4 is lifted, the entire antenna module 2 can be lifted; when the locking button 413 is released, the conical sleeve 403 will slide upward under the action of the spring 405, so that the ball 402 will fall out of the annular groove 242 on the auxiliary extraction rod 24, and the antenna module 2 will be unlocked.

[0072] When implementing: a phased array antenna system that uses a hand-pull fixture for disassembly and assembly, such as Figure 6 As shown, it includes: an antenna frame 1, an antenna module 2 and an electro-hydraulic integrated clustering plate 3. Specifically, the antenna module 2 serves as a signal transceiver unit of a phased array antenna; a plurality of the antenna modules 2 are arranged in an array in the antenna frame 1; an electro-hydraulic integrated clustering plate 3 is provided at the bottom of the antenna frame 1, and the antenna module 2 is plugged and installed on the electro-hydraulic integrated clustering plate 3, and when the two are plugged in, the antenna module 2 and the electro-hydraulic integrated clustering plate 3 are electrically connected and connected to the internal liquid cooling pipeline. Since the antenna modules 2 of the present invention are arranged in an array in the antenna frame 1, and in order to ensure the high integration of the antenna array surface, a plurality of antenna modules 2 are adjacent to each other; therefore, the space for installing and disassembling the antenna modules 2 is limited. In a specific embodiment of the present invention, Figure 1 , Figure 6 As shown, the locking assembly is locked with the auxiliary ejection rod 24, so that the locking handle 4 can lock the antenna module 2, thereby enabling the antenna module to be installed and removed.

[0073] It is worth noting that the hand-pull fixture of the present invention can also be applied to communication modules, electronic control modules and other structural components that require high integration in addition to the antenna module 2, and its application objects do not limit the protection scope of the hand-pull fixture of the present invention.

[0074] Example 2

[0075] A specific embodiment of the present invention provides a method for quickly disassembling and assembling an antenna module, and uses the hand-pull fixture described in Example 1 to install and disassemble the antenna module 2 of the phased array antenna.

[0076] Specifically, the disassembly and assembly method comprises the following steps:

[0077] Step S1: plug and match the auxiliary extraction hole at the bottom of the locking handle 4 with the auxiliary extraction rod 24 fixed above the antenna module 2;

[0078] Step S2: Press the locking button 413 to lock the auxiliary extraction rod 24 through the locking assembly;

[0079] Step S3: After the locking assembly locks the auxiliary extraction rod 24 , the locking handle 4 is assembled into one with the antenna module 2 ; and then the antenna module 2 can be disassembled and assembled by pulling the locking handle 4 .

[0080] In step S1, the ejection-assisting rod 24 is inserted into the ejection-assisting hole at the lower end of the fixed column 404 until the upper end surface of the limiting protrusion 241 of the ejection-assisting rod 24 abuts against the lower surface of the outer shell 408 of the locking handle 4. At this time, the annular groove 242 of the ejection-assisting rod 24 is aligned with the ball 402 nested on the fixed column 404.

[0081] In step S2, the locking process of the locking assembly on the auxiliary extraction rod 24 is as follows:

[0082] Step S21: The locking button 413 presses down the connecting pin 407 through the lever mechanism;

[0083] Specifically, the locking button 413 pushes upward the button pressing block 412 at one end of the transmission lever 410 , and the transmission lever 410 rotates around the rotating shaft 411 , and the other end of the transmission lever 410 presses down the connecting pin 407 of the locking assembly through the pressing block 409 .

[0084] Step S22: the connecting pin 407 drives the pressing sleeve 406 and the cone sleeve 403 to move downward;

[0085] Specifically, the connecting pin 407 slides downward along the U-shaped hole 442 of the fixing column 404 , thereby driving the pressing sleeve 406 to move downward. The pressing sleeve 406 is fixed as a whole with the cone sleeve 403 , and the cone sleeve 403 moves downward along the axial direction of the fixing column 404 synchronously with the pressing sleeve 406 .

[0086] Step S23: The tapered hole at the lower end of the tapered sleeve 403 squeezes the ball 402, and the ball 402 protrudes from the inner surface of the auxiliary hole on the fixed column 404, and then presses the ball 402 into the annular groove 242 of the auxiliary rod 24 to lock the auxiliary rod 24.

[0087] Furthermore, in step S3, after the antenna module 2 is transferred to the specified position, the locking button 413 is released, and the pressing sleeve 406 slides upward under the elastic force of the spring 405, driving the conical sleeve 403 to move upward, thereby releasing the clamping force on the ball 402, and the ball 402 can be moved out of the annular groove 242; the locking handle 4 is pulled upward to separate the locking assembly from the auxiliary extraction rod 24.

[0088] In step S3, after the locking button 413 is released, when the pressing sleeve 406 drives the cone sleeve 403 to move upward, the connecting pin 407 moves upward synchronously and drives the transmission lever 410 to rotate, and the button pressing block 412 fixedly installed at the end of the transmission lever 410 presses down the locking button 413 to reset the locking button 413.

[0089] Furthermore, when the phased array antenna of Example 2 needs to be repaired, the antenna module 2 is disassembled as follows:

[0090] Step C1: Remove the captive screws on the antenna module 2 from the antenna frame 1;

[0091] Step C2: Lock and connect the locking handle 4 and the auxiliary extraction rod 24; the locking method of the locking handle 4 and the antenna module 2 is the same as the locking method in step S22.

[0092] Step C3: lift the locking handle 4 and pull the antenna module 2 out of the antenna frame 1; and move the antenna module 2 to a maintenance point for maintenance.

[0093] In this embodiment, after the locking handle 4 is locked with the antenna module 2, when the entire locking handle 4 is manually lifted, the entire antenna module 2 can be lifted to complete the disassembly action. The inspection and maintenance of the phased array antenna system mainly involves the inspection and maintenance of the antenna module. The antenna module 2 is removed from the electro-hydraulic integrated clustering plate 3 to achieve modular replacement and maintenance of the entire phased array antenna. When the locking button 413 is released, the locking handle 4 is separated from the antenna module 2.

[0094] Compared with the prior art, the technical solution provided by this embodiment has at least one of the following beneficial effects:

[0095] 1. The design of the hand-pull holder of the present invention greatly reduces the replacement and maintenance costs of the phased array antenna; and, compared with the fixed handle, the design of the detachable locking handle 4 does not physically block the transmission direction of the antenna, thereby avoiding the influence on the beam phase, transmission power, etc. of the phased array antenna during operation, which is beneficial to improving the performance of the phased array antenna.

[0096] 2. The hand-pull fixture of the present invention facilitates the insertion and removal of the antenna module 2 through the combination of the locking assembly and the auxiliary extraction rod 24, thereby facilitating the installation of multiple antenna modules 2 in a rectangular array. It has a compact structure and high integration, and effectively reduces the overall space occupied by the phased array antenna.

[0097] 3. The hand-pull fixture of the present invention can lock or unlock the auxiliary pull rod 24 by pressing or releasing the locking button 413, which is simple and convenient to operate. When disassembling and assembling the antenna module 2, the operation difficulty and maintenance time are greatly reduced.

[0098] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
