Description

Technical Field

[0001] This utility model relates to the field of module testing technology, specifically to a quick module assembly and disassembly testing fixture. Background Technology

[0002] With the widespread adoption of drone technology, the security risks it poses are becoming increasingly prominent, making drone countermeasure systems a core component of security for critical infrastructure and important locations. Drone countermeasure equipment typically works by emitting radio frequency (RF) suppression signals in specific frequency bands to drive away or force drones to land. Its core function is achieved through multiple replaceable RF modules designed for different frequency bands (such as GNSS, 2.4GHz, and 5.8GHz). The performance of these modules directly determines the effectiveness of the countermeasure equipment; therefore, rigorous performance testing is essential during manufacturing, maintenance, and repair.

[0003] Currently, the industry's testing methods for these RF modules are generally in a primitive and non-standard rudimentary stage. The typical procedure involves simply binding the module under test (DUT) to a physical support frame using temporary fasteners such as cable ties and tape to simulate its installation in a device. Then, testers manually connect multiple RF cables to the module's RF ports and corresponding test antennas, and finally connect the power for functional verification. However, existing technology is completely inadequate for meeting the demands of efficient testing. Utility Model Content

[0025] like Figures 1 to 6 As shown, this embodiment provides a quick assembly and disassembly testing fixture for modules, including a base 1, a support mechanism 2, a support column 3, a transverse support beam 4, and multiple adapters 5. The support mechanism 2 includes a support arm 21 and multiple support trays 22 for placing modules. The support trays 22 are adaptable to modules 7 of various sizes. The lower end of the support arm 21 is connected to the base 1, and the upper end of the support arm 21 is inclined away from the normal direction of the base 1. The multiple support trays 22 are all connected to the support arm 21, and the multiple support trays 22 are arranged in a stepped layout. The support column 3 is set on the base 1, and the transverse support beam 4 is set on the support column 3. The multiple adapters 5 are detachably arranged on the transverse support beam 4 to realize the radio frequency signal connection and conversion between the antenna 8 and the module 7.

[0026] This technical solution arranges multiple support trays 22 in a stepped manner on the supporting inclined arm 21, facilitating the easy placement of modules 7 into the support trays 22. Each support tray 22 can support at least one module 7, and the support trays 22 are adaptable to modules 7 of various sizes and specifications. This achieves broad support for modules 7 with different physical specifications (including but not limited to external dimensions and interface layouts) using a single support tray 22, significantly improving the overall adaptability and application flexibility of the testing fixture. During module 7 testing, the operator simply places the module 7 to be tested into the designated position on the support tray to complete the installation, completely eliminating the traditional, cumbersome, and non-standard binding operations. This "placing and using" design concept significantly simplifies the operation process, greatly shortens the preparation time for a single test, and lays a core foundation for rapid module replacement and batch testing, thus fully meeting the needs of high-efficiency testing.

[0027] When testing the module using this test fixture, simply install an antenna on the upper end of the adapter 5, and electrically connect the lower end of the adapter 5 to the corresponding interface of the module 7 via an RF cable; then power on the module 7 using an external power supply device to test the module 7.

[0028] In one embodiment, since modules 7 come in various sizes, the carrier tray 22 can be selected to accommodate the largest module 7. The signal transmission interface of module 7 is typically located on its short or long side. Therefore, the carrier tray 22 has a wiring window 223 on its long or short side wall. RF cables can pass through this wiring window 223 to achieve electrical connection between the adapter 5 and the corresponding interface on module 7. Of course, since the signal transmission interface on the side of module 7 is not necessarily located on its long or short side, the carrier tray 22 can have wiring windows on both its long and short sides to meet the wiring requirements of various RF cables.

[0029] Furthermore, the supporting inclined arm 21 is provided with multiple L-shaped holes 211, each L-shaped hole 211 having a limiting side 212 and a communicating side 213; one side of the carrying tray 22 is provided with two lugs 221, the sides of the two lugs 221 away from the carrying tray are connected by a supporting shaft 222; multiple supporting platforms 214 are provided on the side of the supporting inclined arm 21 near the normal direction of the base, and the multiple supporting platforms 214 correspond one-to-one with the multiple L-shaped holes 211. Each carrying tray 22 is embedded in the limiting side of the corresponding L-shaped hole 211 through its supporting shaft 222, and each carrying tray 22 is supported on the corresponding supporting platform 214, making each carrying tray 22 horizontal. Through the cooperation of the limiting side of the L-shaped hole 211 and the supporting platform 214, the carrying tray 22 is kept horizontal, preventing the module 7 placed in the carrying tray 22 from sliding and ensuring that the module 7 is in a horizontal and stable state on the carrying tray 22.

[0030] Meanwhile, a U-shaped arm 11 is provided on the base 1 at the connection point with the supporting mechanism 2, and a limiting shaft 12 is provided inside the U-shaped arm 11; a strip-shaped groove 215 is provided along the length direction of the supporting inclined arm 21, and the communicating side 213 of each L-shaped hole 211 is connected to the strip-shaped groove 215, and the strip-shaped groove 215 is slidably engaged with the limiting shaft 12. A hook 13 is provided on one side of the U-shaped arm 11, and a pin 216 is provided at the lower end of the supporting inclined arm 21, and the pin 216 is engaged in the hanging groove 14 of the hook 13. The pin 216 of the supporting inclined arm 21 is engaged in the hanging groove 14 of the hook 13, and the strip-shaped groove 215 of the supporting inclined arm 21 is slidably engaged with the limiting shaft 12; the limiting shaft 12, the pin 216 and the hanging groove 14 of the hook 13 together realize the tilting guidance and support of the supporting inclined arm 21, ensuring that the supporting inclined arm 21 can be kept in a stable tilted state.

[0031] In addition, such as Figure 6 As shown, when multiple pallets 22 need to be stored, the support arm 21 is pulled up so that its pin 216 disengages from the hanging slot 14 of the hook 13; then, the support shaft 222 of each pallet 22 is slid through the connecting side of the L-shaped hole 211 into the strip groove 215, so that multiple pallets 22 can be stacked on the base 1 for storage. Conversely, multiple pallets 22 can be arranged in a stepped layout and supported horizontally. It is worth noting that the two lugs 221 and the support shaft 222 of the pallet 22 form a borrow space. When the support shaft 222 of the pallet 22 slides through the connecting side of the L-shaped hole 211 into the strip groove 215, the support platform 214 is located within the borrow space of the pallet 22, which effectively avoids interference between the pallet 22 and the support platform 214 when storing, so as to smoothly complete the storage of the pallet 22.

[0032] In some embodiments, hooks 13 are provided on both sides of the U-shaped arm 11, and pins coaxial with the center line are provided on both sides of the lower end of the supporting inclined arm 21. The two pins of the supporting inclined arm 21 are respectively embedded in the hanging grooves of the two hooks 13 of the U-shaped arm 11 to further improve the stability of the engagement between the pins and hooks 13 of the supporting inclined arm 21.

[0033] In one embodiment, the hanging groove 14 of the hook 13 is arranged at an angle, with the open end of the hanging groove 14 facing upwards. The support tray 22 can rely on gravity to allow its pin to slide naturally into the hanging groove 14 of the hook 13 and lock in place, while it is not easy to accidentally come out when subjected to vibration or external force.

[0034] In one embodiment, each L-shaped hole 211 has a limiting protrusion 217 on its limiting side 212 to prevent the support shaft 222 from detaching freely. When the support shaft 222 of the carrying tray 22 is moved close to the limiting side 212 of the L-shaped hole 211, it is necessary to press it firmly to make the support shaft 222 of the carrying tray 22 pass over the limiting protrusion 217 and embed into the limiting side 212 of the L-shaped hole 211, which can effectively prevent the support shaft 222 of the carrying tray 22 from detaching freely from the limiting side 212 of the L-shaped hole 211.

[0035] In one embodiment, the top of the support column 3 has a transverse through-hole mounting groove 31, and a screw 32 is installed in the mounting groove 31. The transverse support beam 4 has a through hole in the middle, and the transverse support beam 4 is sleeved on the screw 32 through the through hole in the middle, and the transverse support beam 4 is locked in the mounting groove 31 by the locking nut 33 that cooperates on the screw 32. The design of the transverse support beam 4 and the mounting groove 31 of the support column 3 can prevent the transverse support beam 4 from rotating during the installation process; it also prevents the transverse support beam 4 from rotating freely due to the loosening of the locking nut 33.

[0036] In one embodiment, the support column 3 has an abutment plane 34 on the side near the support tray; the base 1 has a strip-shaped protrusion 15, and the support tray 22, the strip-shaped protrusion 15, and the abutment plane 34 are arranged parallel to each other along their length; a receiving space for placing the support tray 22 is formed between the strip-shaped protrusion 15 and the abutment plane 34. When storing the support tray 22, multiple support trays 22 can be stacked in an orderly manner within the receiving space formed between the strip-shaped protrusion 15 and the abutment plane 34; and due to the limiting effect of the strip-shaped protrusion 15 and the abutment plane 34, the stacked multiple support trays 22 will not easily move.

[0037] In one embodiment, in order to improve the heat dissipation effect on the module 7 inside the support tray 22, a plurality of heat dissipation holes are provided on the chassis of the support tray 22. The heat dissipation holes can be circular or strip-shaped.

[0038] In one embodiment, there are two support mechanisms 2, which are symmetrically arranged on the base 1.

[0039] In one embodiment, the module quick assembly and disassembly testing fixture also includes a tripod 6 with a mounting base; the base 1 is mounted on the mounting base of the tripod 6. The tripod 6 also has three legs connected to the mounting base, and the legs are telescopic and adjustable. The structure of the tripod 6 is prior art and will not be described in detail here.

[0040] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
