Description

Technical Field

[0001] This utility model belongs to the technical field of test fixtures for FPCs of unmanned aerial vehicles (UAVs), and in particular relates to a test fixture for FPCs of UAVs. Background Technology

[0002] As intelligent devices integrating aviation, electronic, and computer technologies, unmanned aerial vehicles (UAVs) are widely used in aerial surveying, environmental monitoring, and material delivery due to their flexible maneuverability and efficient operation capabilities. Their internal flexible printed circuit boards (FPCs) play a crucial role in signal transmission and power supply. Accurate testing of the FPC is essential for ensuring the stable performance of UAVs. FPC testing fixtures, as core auxiliary equipment in the testing process, directly affect testing efficiency and accuracy. However, most FPC testing fixtures on the market currently use fixed clamping mechanisms, where the clamping components are fixed in relative position to the base. When horizontal rotation testing of the UAV is required, the operator must first loosen the clamping components, rotate the UAV to the target angle, and then re-clamp it. This requires the testing personnel to spend extra time and effort adjusting the UAV during the testing process, resulting in low testing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a test fixture for FPCs used in unmanned aerial vehicles (UAVs). By incorporating a rotating part, specifically, when the angle of the UAV body needs to be adjusted during testing, a motor is started to drive a rotating shaft, which in turn drives a clamping seat to rotate. During rotation, the clamping seat is limited by a limiting groove and a limiting rod, ensuring stability and reducing positional deviation. Simultaneously, the rotation of the clamping seat also drives the UAV body to rotate, thus allowing for flexible adjustment of the UAV's testing angle. This meets multi-angle testing requirements, improves the comprehensiveness of the test, and solves the problem of current commercially available FPC testing fixtures using fixed clamping mechanisms. In these fixtures, the clamping components are fixed in position relative to the base, requiring the operator to first loosen the clamping components, rotate the UAV to the target angle, and then re-clamp it when horizontal angle rotation testing of the UAV is needed.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a test fixture for FPC (Flexible Printed Circuit) of unmanned aerial vehicle (UAV) aircraft, including a base plate and the UAV body, and further comprising:

[0006] A rotating part, mounted on top of the base plate, is used to adjust the angle of the UAV body during testing; and

[0007] A clamping part is installed on the top of the rotating part and is used to clamp the UAV body;

[0008] The base plate serves as the supporting foundation for the rotating and clamping parts, providing stable support for them.

[0009] Furthermore, the rotating part includes a drive assembly mounted on top of the base plate, the drive assembly being used to provide power for adjusting the angle of the drone body; and

[0010] A limiting component is installed on top of the drive component and is used to limit the movement of the UAV body during angle adjustment.

[0011] Among them, the coordinated operation of the drive component and the limit component can provide a stable and reliable angle adjustment function for the testing of the UAV body.

[0012] Furthermore, the clamping part includes an electric push rod, which provides power to the clamping part to clamp the drone body; and

[0013] Support assembly, which provides a support base for the entire clamping part;

[0014] A transmission assembly, mounted on top of a support assembly, is used to convert the power provided by the electric actuator into a force for clamping the drone body.

[0015] A clamping assembly is mounted on top of a transmission assembly and is used to clamp the drone body.

[0016] The transmission component, driven by the electric push rod, converts the driving force of the electric push rod into the clamping force of the clamping component, thereby driving the clamping component to clamp the drone body.

[0017] Furthermore, the drive assembly includes a base fixedly connected to the top of the base plate, a motor installed on the inner wall of the base, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, and a clamping seat installed on the top of the rotating shaft;

[0018] The motor is connected to the inner wall of the base by bolts.

[0019] Furthermore, the limiting component includes a limiting groove formed on the top of the base, and a plurality of limiting rods are fixedly connected to the bottom of the clamping seat, the bottom ends of the plurality of limiting rods extending into the interior of the limiting groove and slidingly connected to the limiting groove.

[0020] There are four limiting rods, which are evenly distributed inside the limiting groove.

[0021] Furthermore, the support assembly includes two support rods fixedly connected to the inner wall of the clamping seat, a support plate fixedly connected to the outer wall of the two support rods, and a fixing rod installed on the top of the support plate;

[0022] The fixing rod is connected to the support plate by welding.

[0023] Furthermore, the transmission assembly includes a slider one slidably connected to the outer walls of the two support rods, a slider two slidably connected to the outer walls of the two support rods, a rhombus block rotatably connected to the top of the fixed rod, and connecting plates hinged between slider one and slider two and the rhombus block respectively.

[0024] The rhomboid block is rotatably connected to the fixed rod via a bearing connection.

[0025] Furthermore, the clamping assembly includes two clamping plates, which are fixedly connected to the top of slider one and slider two respectively. The top of the clamping seat is provided with several sliding grooves. The tops of the two clamping plates extend to the top of the clamping seat and are slidably connected to the corresponding sliding grooves. A pressing block is fixedly connected to the side of the two clamping plates that are close to each other.

[0026] The pressing blocks on the side of the two clamping plates that are close to each other are set to be in an inclined state, forming a certain angle with the corresponding clamping plates.

[0027] This utility model has the following beneficial effects:

[0028] 1. By setting up a rotating part, specifically when the angle of the UAV body needs to be adjusted during the testing process, the motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the clamping seat to rotate. When the clamping seat rotates, it is limited by the limit groove and the limit rod, so that the clamping seat remains stable during rotation and reduces positional deviation. At the same time, the rotation of the clamping seat also drives the UAV body to rotate, thereby flexibly adjusting the test angle of the UAV body, meeting the needs of multi-angle testing, and improving the comprehensiveness of the test.

[0029] 2. By setting up a clamping part, specifically when clamping and fixing the UAV body, the electric push rod is activated to drive slider one to move. When slider one moves, it drives slider two to move through the connecting plate and the diamond block, so that slider one and slider two move closer or further apart, and drive the clamping plate to move. This causes the extrusion block to press and fix the support leg on the UAV body at a specific angle, thereby realizing the rapid clamping and releasing of the UAV body, providing reliable fixation for testing, preventing the UAV body from shifting during the test, and ensuring the smooth progress of the test.

[0030] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The output shaft of the motor 212 is fixedly connected to a rotating shaft 213 via a coupling. A clamping seat 214 is installed on the top of the rotating shaft 213.

[0054] The electric push rod 31 is fixed to the inner bottom wall of the clamping seat 214 by bolt connection.

[0055] The limiting component 22 includes a limiting groove 221 formed on the top of the base 211, and a plurality of limiting rods 222 are fixedly connected to the bottom of the clamping seat 214. The bottom ends of the plurality of limiting rods 222 extend into the interior of the limiting groove 221 and are slidably connected to the limiting groove 221.

[0057] The support assembly 32 includes two support rods 321 fixedly connected to the inner wall of the clamping seat 214, a support plate 322 fixedly connected to the outer wall of the two support rods 321, and a fixing rod 323 installed on the top of the support plate 322.

[0059] The transmission assembly 33 includes a slider 331 that is slidably connected to the outer wall of two support rods 321, a slider 332 that is slidably connected to the outer wall of the two support rods 321, a rhombus block 333 that is rotatably connected to the top of the fixed rod 323, and a connecting plate 334 that is hinged between the slider 331 and the slider 332 and the rhombus block 333 respectively.

[0060] Among them, the rhombus block 333 is connected to the outer wall of the bearing, and the fixing rod 323 is connected to the inner wall of the bearing.

[0061] The clamping assembly 35 includes two clamping plates 351, which are fixedly connected to the top of slider 1 331 and slider 2 332 respectively. The top of the clamping base 214 is provided with a plurality of sliding grooves 352. The top of the two clamping plates 351 extends to the top of the clamping base 214 and is slidably connected to the corresponding sliding grooves 352. The two clamping plates 351 are fixedly connected to the side of each other that is close to each other.

[0062] Among them, the pressing blocks 353 on the side of the two clamping plates 351 that are close to each other are both set to an inclined state, forming a certain angle with the corresponding clamping plate 351.

[0063] A specific application of this embodiment is as follows: When using this device, the base plate 1 is first fixed to the testing table by bolt connection. Then, the drone body 11 to be tested is placed on the top of the clamping seat 214. The clamping part 3 clamps the drone body 11. During the testing process, if it is necessary to adjust the test angle of the drone body 11, the motor 212 is started. The motor 212 drives the rotating shaft 213 to rotate. When the rotating shaft 213 rotates, it drives the clamping seat 214 to rotate. Thus, the clamping seat 214 drives the drone body 11 to rotate, thereby adjusting the angle of the drone body 11. At the same time, when the clamping seat 214 rotates, it will drive the limiting rod 222 to slide in the limiting groove 221. The limiting groove 221 and the limiting rod 222 limit the clamping seat 214, thereby ensuring that the rotation process of the clamping seat 214 remains stable.

[0064] When the drone body 11 is placed on top of the clamping base 214 to clamp the drone body 11, the electric push rod 31 on the bottom wall inside the clamping base 214 is first activated. The electric push rod 31 will drive the slider 1 331 to slide on the support rod 321. During the sliding of the slider 1 331 on the support rod 321, the rhombus block 333 will rotate around the fixed rod 323 as the axis through the connecting plate 334 connected to the slider 1 331. At the same time as the rhombus block 333 rotates, it will also drive the slider 2 332 to slide on the support rod 321 through the connecting plate 334 connected to the slider 2 332. Therefore, the extension and retraction of the output shaft of the electric push rod 31 can drive the slider 1 331 and the slider 2 332 to move closer or further apart. When the slider 1 331 and the slider 2 332 move, they will also... The clamping plate 351 is moved, and the clamping plate 351 is limited by the slide groove 352 during the movement, making the movement of the slide groove 352 more stable. When the slider 1 331 and slider 2 332 approach each other, the pressing blocks 353 on the two clamping plates 351 also approach each other and contact the support legs of the drone body 11 at a specific angle. Thus, the oblique force is used to press and fix the support on the left and right sides of the drone body 11, thereby achieving the effect of firmly clamping the drone body. At the same time, the inclined pressing block 353 can adapt to the support legs of the drone body 11 with different diameters within a certain range. When the slider 1 331 and slider 2 332 move away from each other, the two clamping plates 351 move away from each other, thereby releasing the clamping and fixing of the drone body 11.
