[0019] Implementation Method 1 like Figures 1-2 As shown, this application discloses a test fixture for a gesture detection sensor, including a base 10, a three-axis platform 20, and a mounting end 30 for mounting a sensor under test 40. The base 10 includes a panel 11, and the mounting end 30 is disposed on the panel 11 of the base 10 and electrically connected to the base 10. The three-axis platform 20 includes a stand 22, a plate 23, and a rotating rod 21 rotatably connected to the plate 23. The plate 23 is slidably connected to the stand 22 vertically, and the stand 22 is fixed on the base 10. When the rotating rod 21 moves, the sensor under test 40 scans the movement state of the rotating rod 21, and the base 10 detects the scanned movement state of the sensor under test 40.

[0020] In the above embodiments, the test fixture disclosed in this application includes a three-axis platform 20, which includes a stand 22, a plate 23, and a rotating rod 21 rotatably connected to the plate 23. The plate 23 is slidably connected to the stand 22 perpendicularly. Because the rotating rod 21 is rotatably connected to the plate 23, the rotating rod 21 can rotate in a plane. Furthermore, because the plate 23 is slidably connected to the stand 22 perpendicularly, the plate 23 can slide vertically. This allows the plate 23 to drive the rotating rod 21 to move in multiple directions in the horizontal and vertical planes, accurately simulating the movement of hand gestures, and thus comprehensively evaluating the multi-directional performance of the sensor 40 under test.

[0021] The base 10 includes a controller 16, which is equipped with software that can analyze the motion state scanned by the sensor 40 under test; the plate 23 is a smooth plate, the rotating rod 21 rotates along the plate 23 in the horizontal plane, and the plate 23 slides along the stand 22 in the vertical plane, thereby moving the rotating rod 21 in three-dimensional space.

[0022] Implementation Method 2 In a preferred embodiment, such as Figures 1-2 As shown, the three-axis platform 20 also includes a motor 24, the rotating rod 21 is disposed on the upper end surface of the plate 23, the motor 24 is disposed on the lower end surface of the plate 23, and the rotating rod 21 is fixed on the rotating shaft of the motor 24. Figure 5 As shown, the support frame 22 is provided with a sliding groove 223 and a frame 221, and the flat plate 23 is vertically slidably connected to the support frame 22 via the sliding groove 223. A scale 222 is provided on the frame 221. Preferably, the length of the rotating rod 21 is greater than the distance from the flat plate 23 to the mounting end 30, the flat plate 23 is arranged parallel to the mounting end 30, and the rotating rod 21 is a hand-shaped rod.

[0023] In the above embodiment, the motor 24 can drive the rotating rod 21 to rotate on the upper surface of the plate 23. The plate 23 can be manually or by a cylinder to slide vertically on the stand 22, thereby driving the rotating rod 21 to move up and down. The scale 222 is useful for measuring the vertical sliding amount of the plate 23. The length of the rotating rod 21 is greater than the distance from the plate 23 to the mounting end 30. The plate 23 is set parallel to the mounting end 30, and one end of the rotating rod 21 can be rotated to be directly above the mounting end 30, which facilitates the sensor under test 40 to better scan the movement state of the rotating rod 21. In order to better simulate gestures, the rotating rod 21 is a hand-shaped rod. In order to facilitate the rotation of the rotating rod 21, the lower end of the hand-shaped rod is flat. It is understood that, in order to make the movement of the rotating rod 21 more versatile, the stand 22 can also be slidably connected to the base 10.

[0024] Implementation Method 3 In a preferred embodiment, such as Figure 3 As shown, the mounting end 30 includes an end body 31 and an end cap 32 rotatably connected to the end body 31. The end body 31 is provided with a mounting hole 311 for mounting the sensor under test 40. The end cap 32 includes a through hole 321 and a glass cover 322 disposed on the through hole 321, the through hole 321 communicating with the mounting hole 311. Preferably, the end of the end body 31 is provided with a slot, and the end cap 32 is provided with a buckle 323 corresponding to the slot, the buckle 323 engaging with the slot.

[0025] In the above embodiments, the end cap 32 allows the sensor under test 40 to be installed more stably and also protects the sensor under test 40, such as... Figure 6 As shown, the sensor under test 40 is plugged into the mounting hole 311 via pin 41. The glass cover 322 facilitates observation of the sensor under test 40 and also facilitates the sensor under test scanning the rotating rod 21. The buckle 323 facilitates the engagement of the end cap 32 with the end body 31.

[0026] Implementation Method 4 In a preferred embodiment, such as Figure 4 As shown, the base 10 also includes a controller 16, a power supply 14, and a circuit board 15 electrically connected to each other. The base 10 also has a cavity 13, and the panel 11 is fixed to the upper end of the cavity 13. The controller 16, the power supply 14, and the circuit board 15 are all disposed within the cavity 13. Figure 1 As shown, the panel 11 includes a button 111 and a display screen 12. The motor 24, the mounting end 30, the button 111 and the display screen 12 are all electrically connected to the controller 16.

[0027] In the above embodiment, the controller 16 is equipped with software that analyzes and compares the motion state of the rotating rod 21 and the motion data scanned by the sensor under test 40. The performance of the sensor under test 40 is determined through this analysis and comparison software. Multiple controllers 16 and mounting terminals 30 can be configured, with one controller 16 capable of detecting one sensor under test 40 on one mounting terminal 30. The power supply 14 provides various currents, and the circuit board 15 performs conversions of various currents and signals. The button 111 controls the operation of the test fixture, and the display screen 12 displays various test data.

[0028] This test fixture tests the sensor under test in the following manner: Step 1: Install the test fixture. First, install the three-axis platform 20 on the base 10, ensuring that the three-axis platform 20 can operate stably. Next, install the sensor under test 40 on the mounting end 30 of the test fixture to detect or scan the movement trajectory direction of the rotating rod 21 on the three-axis platform. Finally, install the controller inside the base 10 of the test fixture to control the operation of the test fixture. Step Two: Set Test Parameters. First, set the movement range of the rotating rod 21 using the controller 16. For example, the movement range of the rotating rod 21 on the X-axis is -50mm to 50mm, on the Y-axis it is -50mm to 50mm, and on the Z-axis it is 0mm to 100mm. Then, set the test mode using the controller 16, such as single-axis test, dual-axis test, or multi-axis test mode.

[0029] Step 3: Start the test fixture. First, the controller 16 starts the motor 24, driving the rotating rod 21 on the three-axis platform to move accordingly (up, down, left, and right). Simultaneously, the sensor under test 40 begins detecting the movement trajectory of the rotating rod 21 and feeds the detection result back to the controller. Then, the controller determines the functionality of the sensor under test 40 based on the feedback result.

[0030] Step 4: Record Test Results. First, the controller records the movement trajectory status and test results (data) detected or scanned by the sensor under test 40. Then, the recorded data is analyzed using appropriate data analysis software to generate a test report. This test report includes the test parameters, test results, and test conclusions.

[0031] In summary, this test fixture simulates hand gestures using a rotating rod 21 on a three-axis platform, enabling multi-directional movement. This allows the sensor under test to detect or scan and obtain motion parameters. Finally, the controller compares and analyzes the parameters to obtain test results, thus comprehensively evaluating the multi-directional performance of the sensor under test.
