The lateral movement structure 1 is installed on the clamping rotary base 4 by bolts. The fixed end of the rotary structure 2 is installed on the top of the lateral movement structure 1. The sound insulation and sealing cover 5 covers the entire lateral movement structure 1 and the fixed end of the rotary structure 2. The telescopic end of the rotary structure 2 passes through the sound insulation and sealing cover 5 and is connected to the flexible clamping structure 3.

[0024] The lateral movement structure 1 is used to enable the flexible clamping structure 3 to move laterally, so as to realize the lateral pushing of the upper cover by the flexible clamping structure 3. The rotary structure 2 is used to enable the flexible clamping structure 3 to rotate along the axis of the flexible clamping structure 3, so as to realize the flipping of the upper cover by the flexible clamping structure 3. The flexible clamping structure 3 is used to clamp or push the upper cover to realize the rotation noise and lateral pushing noise of the test earphone charging box. The clamping rotary base 4 is used to fixedly install the lateral movement structure 1, realize the longitudinal position adjustment of the lateral movement structure 1, and play a load-bearing role. The sound insulation and sealing cover 5 is used to reduce the noise generated when the lateral movement structure 1 and the rotary structure 2 are operating, and avoid interfering with the noise abnormal sound test of the earphone charging box.

[0025] As Figure 3 shown, the lateral movement structure 1 includes a lateral movement motor 11, a belt 12, a driven wheel 13, a clamping member 14, a track base 15, two first guide rails 16, and a lateral slider 19. The two first guide rails 16 are installed on the clamping rotary base 4 through the track base 15. The lateral movement motor 11 is installed on the left side of the track base 15 by bolts. The driven wheel 13 is installed on the rear side of the track base 15. The lateral slider 19 is installed on the two first guide rails 16 so as to be movable laterally. The driving wheel of the lateral movement motor 11 is connected to the driven wheel 13 through the belt 12. The clamping member 14 is installed on the belt 12. The clamping member 14 is connected to the rear end of the lateral slider 19 by bolts. A first displacement induction piece 18 is installed at the front end of the lateral slider 19. Three first position sensors 17 are evenly installed on the track base 15. During the lateral sliding process of the lateral slider 19, it passes through the three first position sensors 17 in sequence.

[0026] The lateral movement motor 11 indirectly provides power for the lateral movement of the lateral slider 19. The belt 12 plays a transmission role. The driven pulley 13 is used to adjust the tightness of the belt 12. The clamping member 14 is used to connect the lateral slider 19 and the belt 12 to achieve transmission. The track base 15 is used to fixedly install two first guide rails 16 so that the levels of the two first guide rails 16 are the same. The cooperation between the first guide rail 16 and the lateral slider 19 plays a role in guiding and reducing friction. The first position sensor 17 is used to detect the position of the lateral slider 19.

[0027] As Figure 4 shown, the rotating structure 2 includes a rotation angle motor 21, a first motor fixing base 22, a coupling 23, a rotating shaft fixing base 24, a rotating rod 27 and a rotating substrate 28.

The rotating shaft fixing base 24 is installed on the right side of the rotating substrate 28. The rotation angle motor 21 is installed on the first motor fixing base 22. The rotating rod 27 is rotatably installed on the rotating shaft fixing base 24 along the axial direction of the rotating rod 27. The rotation angle motor 21 is connected to the left end of the rotating rod 27 through the coupling 23. A rotation induction piece 26 is provided on the rotating rod 27, and four angle sensors 25 are installed on the rotating shaft fixing base 24. When the rotating rod 27 rotates, the rotation induction piece 26 will sequentially pass through the four angle sensors 25. The right end of the rotating rod 27 passes through the sound insulation and sealing cover 5 and is connected to the flexible clamping structure 3.

[0028] The rotation angle motor 21 provides power for the rotation of the rotating rod 27, thereby realizing the flipping of the upper cover. The first motor fixing base 22 is used to fixedly install the rotation angle motor 21. The coupling 23 is used to connect the rotation angle motor 21 and the rotating rod 27. The rotating shaft fixing base 24 is used to fix the rotating rod 27 and plays a supporting role. The rotating rod 27 plays a transmission role, and the power of the rotation angle motor 21 is transmitted to the flexible clamping structure 3. The rotating substrate 28 keeps the rotating shaft fixing base 24 and the first motor fixing base 22 on the same horizontal plane and plays a load-bearing role. The cooperation between the rotation induction piece 26 and the four angle sensors 25 realizes the monitoring of the rotation angle of the rotating rod 27 and realizes the flipping of the upper cover.

[0029] As Figures 5-7As shown, the flexible clamping structure 3 includes a flexible clamping assembly and a first flexible pushing assembly. The flexible clamping assembly includes a connection base 31, a motor protection cover 32, a gripper motor 33, a motor mounting base 34, a connecting rod assembly 35, and two flexible grippers 37. Each flexible gripper 37 includes a clamping rod 372 and a flexible block 371. The first flexible pushing assembly includes a push rod fixing seat 36, a first flexible contact part 39, and a first pressure sensor 38. The connecting rod assembly 35 includes a threaded block 351, two connecting rods 352, and two L-shaped connecting rods 353. The rotating rod 27 of the rotating structure 2 is clamped in the connection base 31. One side of the connection base 31 away from the rotating rod 27 is connected to the left end of the motor protection cover 32. The right end of the motor protection cover 32 is connected to the motor mounting base 34. The motor mounting base 34 is of a U-shaped structure. The gripper motor 33 is located between the motor protection cover 32 and the motor mounting base 34 and is mounted on the motor mounting base 34. One side of the motor mounting base 34 away from the gripper motor 33 is connected to the push rod fixing seat 36. The rotating shaft of the gripper motor 33 passes through the through hole of the motor mounting base 34 and is connected to the threaded block 351 by a thread. The two ends of the threaded block 351 are respectively hinged to one end of the two connecting rods 352. The other ends of the two connecting rods 352 are hinged to the middle parts of the two L-shaped connecting rods 353. The longitudinal ends of the two L-shaped connecting rods 353 are hinged to the two ends of the motor mounting base 34. The transverse ends of the two L-shaped connecting rods 353 are respectively connected to one end of the two clamping rods 372. The other ends of the two clamping rods 372 are connected to the two flexible blocks 371. The flexible block 371 is made of silicone. The first flexible contact part 39 is mounted on one side of the push rod fixing seat 36 away from the motor mounting base 34 through the first pressure sensor 38. The first flexible contact part 39 is made of silicone. The first flexible contact part 39 is located between the two flexible grippers 37. The lengths of the two flexible grippers 37 are greater than that of the first flexible contact part 39. A second position sensor 3354 is mounted on the side of the motor protection cover 32. A second displacement induction piece 3361 is mounted on the threaded block 351. When the two flexible grippers 37 open or approach, the second displacement induction piece 3361 moves horizontally and passes through the second position sensor 3354.

[0030] The connecting base 31 connects the rotating rod 27 and the motor protection cover 32, and cooperates with the rotating rod 27 to adjust the angle of the flexible clamping structure 3 to adapt to different types of earphone charging cases. The motor protection cover 32 protects the claw motor 33 and is used to install the second position sensor 3354. The claw motor 33 provides power for the opening or closing of the two flexible claws 37. The motor mounting seat 34 is used to mount the claw motor 33. The connecting rod assembly 35 converts the rotation of the claw motor 33 into the opening and closing power of the two flexible claws 37, playing a transmission role. The push rod fixing seat 36 is used to fix the first flexible contact part 39. The two flexible claws 37 are used to clamp or release the upper cover of the earphone charging case and avoid damaging the upper cover of the earphone charging case, so as to realize the flipping of the upper cover. The first flexible contact part 39 is used to push the left end of the upper cover to test whether abnormal noise is generated when the rotating shaft is stressed on the left side. The first pressure sensor 38 is used to detect the pressure of the first flexible contact part 39 on the upper cover to avoid damaging the earphone charging case due to excessive thrust. The mutual cooperation of the second displacement sensing piece 3361 and the second position sensor 3354 realizes the monitoring of the relative displacement of the threaded block 351.

[0031] As Figure 8 shown, the sound insulation seal cover 5 includes a sound insulation layer 51, a protection cover 52 and a sealing ring 53. The protection cover 52 includes an upper frame and a lower frame, and the upper frame communicates with the lower frame. The inner walls of the upper frame and the lower frame are both covered with the sound insulation layer 51. The sound insulation layer 51 forms a sound insulation cavity. At the bottom of the lower frame, it is respectively installed on the clamping and rotating base 4 of the flexible rotating clamping mechanism, the flexible pushing base 611 of the first flexible pushing mechanism 6, and the flexible pushing base 611 of the second flexible pushing mechanism 8 through the sealing ring 53.

[0032] The sound insulation layer 51 is used to improve the sound insulation effect of the protection cover 52. The protection cover 52 protects the power part of the flexible rotating clamping mechanism and avoids harming the operator. The sealing ring 53 improves the sealing performance of the protection cover 52 with the flexible rotating clamping mechanism, the first flexible pushing mechanism 6 and the second flexible pushing mechanism 8, and further reduces the noise during the operation of the equipment.

[0033] Description of the noise and abnormal noise test process of the earphone charging case using this test mechanism:

[0034] The earphone charging case includes a cabin body, a rotating shaft and an upper cover. The cabin body is connected to the upper cover by rotation, and the upper cover can rotate relative to the cabin body. First, the cabin body is fixed by a fixing fixture, and the upper cover is located above the cabin body.

[0035] (1)Description of the process of the upper cover flipping test: The flexible gripper 37 is in the open state. Under the action of the lateral movement structure 1, the flexible gripper 37 moves to the front and rear of the upper cover. Under the action of the gripper motor 33 of the flexible clamping structure 3, the flexible gripper 37 clamps the front and rear sides of the upper cover. Under the action of the rotation structure 2, the flexible gripper 37 holds the upper cover and reciprocally flips it relative to the cabin body. The operator judges whether there is abnormal noise in the earphone charging box by listening.

[0036] (2)After the upper cover flipping test is completed, the flexible gripper 37 is in the open state. Under the action of the lateral movement structure 1, the first flexible contact part 39 presses from the side of the upper cover. Since the cabin body is in a fixed state, the upper cover drives the cabin body to be stressed through the rotating shaft. The operator judges whether the earphone charging box makes noise by listening.

[0037] The above specific implementation manners are the preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods made without departing from the technical solution of the present invention are included in the protection scope of the present invention.
