[0003] Phased array radar technology, with its advantages of rapid beam agility and strong multi-target tracking capabilities, has become an ideal choice for UAV reconnaissance. Currently, the chassis used for testing phased array antennas are mounted on the UAV. Due to the limited internal space of the UAV, positioning the chassis is inconvenient, and the chassis assembly and disassembly process is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-release chassis for testing phased array antennas, which can quickly position and fix the chassis, making the disassembly and assembly of the chassis more convenient, quick, time-saving and labor-saving, thereby improving work efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A quick-release chassis for testing a phased array antenna includes a chassis body, a bracket, a positioning block, and a locking component. The chassis body is mounted on the bracket, and the positioning block and locking component are respectively located on both sides of the bracket. The bottom of the two opposite side walls of the chassis body are respectively provided with positioning grooves and slots.

[0008] Furthermore, the locking assembly includes a latch, a locking block, and a fixing block. The fixing block is located at the bottom of the support plate, the latch slides through the fixing block, and the locking block is located between the latch and the fixing block. When the latch slides toward the fixing block, it can push the locking block to abut against the fixing block and engage the locking block with the slot. When the latch slides away from the fixing block, it can disengage the locking block from the slot.

[0009] Furthermore, a countersunk hole is provided on the side of the fixed block opposite to the locking block, and a through hole communicating with the countersunk hole is provided on the side of the fixed block opposite to the locking block. The latch includes a lock head, a lock rod, a spring, and a locking pin. One end of the lock rod is connected to the lock head, and the other end of the lock rod is inserted into the countersunk hole through the through hole and locked with the locking pin. The spring is sleeved on the lock rod, and both ends of the spring abut against the locking pin and the bottom of the countersunk hole, respectively. The locking block is sleeved on the lock rod between the lock head and the fixed block.

[0010] Furthermore, the top of the locking block on the side opposite to the fixing block is provided with a locking block that engages with the locking slot.

[0011] Furthermore, the bottom surface of the fixing block is provided with a sliding groove, and the bottom side of the locking block opposite to the fixing block is provided with a slider that slides in cooperation with the sliding groove.

[0012] Furthermore, the card slot and the positioning slot have the same shape, and the groove surface that contacts the bottom of the card block is a rectangular sloping surface.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model uses a bracket, positioning block, and locking component to fix the bracket onto the drone. When installing the chassis, the chassis body is first placed on the bracket, and the positioning block engages with the positioning slot to position the chassis body. Then, by operating the locking component, the locking component engages with the slot, clamping the bottom of the chassis between the positioning block and the locking component, thereby locking the chassis. By operating the locking component to disengage from the slot, the chassis body can be unlocked, ultimately achieving quick assembly and disassembly of the chassis body. The overall structure is stable, the operation is convenient and quick, saving time and effort, and improving work efficiency. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] like Figures 1-4 As shown, a quick-release chassis for testing a phased array antenna includes a chassis body 1, a bracket 2, a positioning block 3, and a locking component 4. The positioning block 3 and the locking component 4 are respectively located on both sides of the bracket 2. The bottom of the two opposite side walls 11 of the chassis body 1 are respectively provided with positioning grooves and slots 5. The bracket 2 is fixed on the UAV. When installing the chassis, the chassis body 1 is first placed on the bracket 2, so that the positioning block 3 engages with the positioning groove to position the chassis body 1. Then, by operating the locking component 4, the locking component 4 engages with the slot 5, so that the bottom of the chassis is clamped between the positioning block 3 and the locking component 4, thereby locking the chassis. By operating the locking component 4 to disengage from the slot 5, the chassis body 1 can be unlocked.

[0026] like Figure 2 As shown, the bracket 2 includes a base plate 21, a support plate 22, and a support column 23. The base plate 21 is fixed to the UAV, and the support plate 22 is fixedly supported on the base plate 21 by the support column 23. The support plate 22 is used to place the chassis body 1. The positioning block 3 and the locking component 4 are fixed on both sides of the support plate 22 respectively.

[0027] like Figure 3 , Figure 5 As shown, the locking assembly 4 includes a latch 41, a locking block 42, and a fixing block 43. The fixing block 43 is fixed to the bottom of the support plate 22. The latch 41 slides through the fixing block 43, and the locking block 42 is located between the latch 41 and the fixing block 43. More specifically, as shown... Figures 5-7 As shown, the fixed block 43 has a countersunk hole 6 on the side opposite to the locking block 42, and a through hole 7 communicating with the countersunk hole 6 on the side opposite to the locking block 42. The latch 41 includes a lock head 411, a lock rod 412, a spring 413, and a locking pin 414. One end of the lock rod 412 is fixedly connected to the lock head 411, and the other end of the lock rod 412 is inserted into the countersunk hole 6 through the through hole 7 and locked with the locking pin 414. The spring 413 is sleeved on the lock rod 412, and both ends of the spring 413 abut against the locking pin 414 and the bottom of the countersunk hole 6, respectively. The locking block 42 is sleeved on the lock rod 412 between the lock head 411 and the fixed block 43.

[0028] When installing the chassis, the locking head 411 drives the locking rod 412 away from the fixing block 43, causing the spring 413 to compress. At the same time, the locking block 42 moves away from the fixing block 43, placing the chassis body 1 on the support plate 22 and positioning it through the cooperation of the positioning block 3 and the positioning groove. Then, the locking head 411 is released. Under the restoring force of the spring 413, the locking rod 412 drives the locking head 411 to slide towards the fixing block 43. The locking head 411 then pushes the locking block 42 towards the fixing block 43, so that the locking block 42 abuts against the fixing block 43 and engages with the slot 5, thereby locking the chassis body 1. The chassis body 1 can be unlocked by the locking head 411 driving the locking rod 412 away from the fixing block 43 again, causing the locking block 42 to disengage from the slot 5.

[0029] like Figure 5 , Figure 8 As shown, a locking block 8 is provided on the top of the side of the locking block 42 opposite to the fixing block 43. When locking the chassis body 1, the locking block 42 engages with the slot 5 through the locking block 8. A sliding groove 9 is provided on the bottom surface of the fixing block 43. A slider 10 is fixed on the bottom of the side of the locking block 42 opposite to the fixing block 43 and slides with the sliding groove 9. The sliding engagement between the slider 10 and the sliding groove 9 allows the locking block 42 to move smoothly, preventing the locking block 42 from rotating and causing the locking block 8 and the slot 5 to become misaligned, thus preventing the chassis body 1 from being locked.

[0030] Card slot 5 has the same shape as the positioning slot, such as Figure 2 As shown, the groove surface where the card slot 5 contacts the bottom of the card block 8 is a rectangular sloping surface, which allows the locking component 4 and the positioning block 3 to provide the chassis body 1 with a large load-bearing capacity when the aircraft is making a side landing, thereby maintaining the overall stability of the chassis.

[0031] Through the arrangement of the bracket 2, positioning block 3, and locking component 4 and their related working principles, this utility model can quickly position and fix the chassis, making chassis assembly and disassembly more convenient, quick, time-saving, and labor-saving, thereby improving work efficiency.

[0032] Finally, although embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
