[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-9 As shown, the present invention is a viewing angle detection system for an LED display screen, comprising a base 1, a fixing platform 2, a first detector 3 and a second detector 4. The base 1 is provided with a mounting cavity 9, the fixing platform 2 is fixedly connected to the base 1, and clamping and fixing mechanisms are provided on both sides of the fixing platform 2. The base 1 is provided with a guide groove 10, a guide groove 2 5 and an avoidance groove 8, and the avoidance groove 8 is located in the middle position of the guide groove 2 5. The setting of the avoidance groove 8 allows the second detector 4 to drop into the avoidance groove 8 when passing in front of the first detector 3 during the process of moving from one side of the display screen to the other side along the guide groove 2 5, so as to avoid affecting the detection of the first detector 3.

[0022] A mounting seat 55 is slidably connected to the guide groove 10, and the first detector 3 is installed on the mounting seat 55, and a sliding mechanism 1 is provided inside the mounting cavity 9 below the guide groove 10. The sliding mechanism 1 can drive the first detector 3 to move along the guide groove 10, and can have a good viewing angle detection effect for display screens of different sizes. A mounting seat 2 17 is slidably connected to the guide groove 2 5, and the second detector 4 is installed on the mounting seat 2 17, and a sliding mechanism 2 is provided inside the mounting cavity 9 below the guide groove 2 5. The second detector 4 can be driven to move along the guide groove 2 5 by the sliding mechanism 2. Since the guide groove 2 5 extends from the left side of the display screen to the right side of the display screen, it can completely cover the entire display screen. In this way, the viewing angle of the display screen can be detected at different angles on the left and right sides of the display screen by using only one second detector 4, thereby reducing the viewing angle detection cost and improving the viewing angle detection efficiency.

[0023] The base 1 is also provided with a wire groove 15 and a wire groove 23. The first detector 3 is connected to a wire 7, which extends to the inside of the wire groove 15. A wiring mechanism 1 is provided inside the installation cavity 9 below the wire groove 15. The wiring mechanism 1 can make the wiring of the wire 7 more regular, ensuring that the exposed length of the connecting wire 7 can be shortened to the greatest extent when the first detector 3 slides, so as to avoid interfering with the normal operation of the device.

[0024] The second detector 4 is connected to a wire 6, which extends to the inside of a wire trough 23. A wiring mechanism 2 is provided below the wire trough 23 and located inside the installation cavity 9. The wiring mechanism 2 can make the wiring of the wire 6 more regular on the one hand, and on the other hand, prevent the wire 6 from blocking the front of the first detector 3 when the second detector 4 moves to the right side of the first detector 3, thereby interfering with the movement of the first detector 3.

[0025] The clamping and fixing mechanism includes a support 12, a support 14, a clamping plate 35, a threaded rod 37 and a guide rod 36. The threaded rod 37 is rotatably connected between the support 12 and the support 14.

Two clamping plates 35 are provided and are arranged on both sides of the fixed platform 2. The clamping plate 35 is threadedly connected to the threaded rod 37 and is slidably connected to the guide rod 36. The diameter of the through hole on the fixed platform 2 that matches the threaded rod 37 is larger than the diameter of the threaded rod 37, and the threaded rod 37 does not contact the through hole. The support 12 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to the threaded rod 37. The threaded rod 37 is driven to rotate by the motor 11, and the clamping plate 35 is driven to approach the display screen when the threaded rod 37 rotates.

[0026] A placement groove 13 is provided on the fixing platform 2. The depth of the placement groove 13 is adapted to the width of the plastic frame at the bottom edge of the display screen, which can not only limit and fix the bottom of the display screen, but also avoid blocking the display screen. A clamping groove 38 is provided on the clamping plate 35. A clamping block 39 is movably installed inside the clamping groove 38. The clamping block 39 is provided with an opening and a chamfer is provided at the opening. When the clamping plate 35 moves toward the display screen, it can drive the clamping block 39 to clamp and fix the two sides of the display screen. The clamping block 39 is made of rubber material, which can protect the display screen and prevent the left and right edges of the display screen from being damaged by the clamping block 39. The chamfer setting can facilitate the clamping and fixing of the edge of the display screen.

[0027] The sliding mechanism 1 includes a motor 21, a support plate 2 53 and a threaded rod 2 56. Two support plates 2 53 are provided and fixedly connected inside the mounting cavity 9. A threaded rod 2 56 is rotatably installed between the two support plates 2 53. The motor 21 is fixedly connected inside the mounting cavity 9. The output end of the motor 21 is fixedly connected to the threaded rod 2 56. A guide rod 3 54 is fixedly connected to the guide groove 10. The mounting seat 1 55 is threadedly connected to the threaded rod 2 56 and is slidably connected to the guide rod 3 54. The motor 21 can drive the threaded rod 2 56 to rotate, and the threaded rod 2 56 drives the mounting seat 1 55 to slide in the guide groove 10, so that the first detector 3 can move forward and backward.

[0028] The sliding mechanism 2 includes an upper rod 27, a lower rod 30 and a collar 19. The upper rod 27 is fixedly connected to the lower part of the mounting seat 217. The other end of the upper rod 27 passes through the guide groove 25 and extends to the inside of the mounting cavity 9 and is fixedly connected to a support platform 1 28. A roller 26 is rotatably installed on the outer wall of the upper rod 27. The roller 26 rotates with the guide groove 25. The setting of the roller 26 can make the upper rod 27 move more smoothly in the guide groove 25. The lower end of the support platform 1 28 is fixedly connected to the lower rod 30. The bottom end of the lower rod 30 is fixedly connected to a limiting disk 32. The outer wall of the lower rod 30 is sleeved with the collar 19 and the lower rod 30 is slidably connected to the collar 19. The upper end of the collar 19 is fixedly connected to a support platform 2 31. A spring 29 is fixedly connected between the support platform 2 31 and the support platform 1 28.

[0029] The setting of spring 1 29 can pull the mounting seat 2 17 closer to the upper surface of the base 1, so that the ball 24 is always in close contact with the upper surface of the base 1, ensuring the stability of the second detector 4 when moving. At the same time, when the second detector 4 moves into the avoidance groove 8, under the action of spring 1 29, the lower rod 30 is pulled downward along the ring 19, so that the mounting seat 2 17 drives the second detector 4 to descend into the avoidance groove 8.

[0030] The edges of the mounting seat 17 are provided with rounded corners, and the lower end of the mounting seat 17 is fixedly connected to two support rods 25, and the bottoms of the support rods 25 are rotatably installed with balls 24. The setting of the rounded corners on the mounting seat 17 and the setting of the balls 24 on the support rods 25 can make the mounting seat 17 move out of and into the avoidance groove 8 more smoothly.

[0031] A motor three 34 is also fixedly connected to the interior of the mounting cavity 9, and a connecting rod one 20 is fixedly connected to the output shaft of the motor three 34. The other end of the connecting rod one 20 is rotatably connected to the connecting rod two 33, and the end of the connecting rod two 33 away from the connecting rod one 20 is fixedly connected to the ring 19. When the motor three 34 rotates, it drives the connecting rod one 20 to swing, the connecting rod one 20 drives the connecting rod two 33 to swing, the connecting rod two 33 drives the ring 19 to swing, the ring 19 drives the lower rod 30 and the upper rod 27 to move along the guide groove two 5, so that the upper rod 27 drives the mounting seat two 17 to move, and the mounting seat two 17 drives the second detector 4 to move to different angles of the display screen for viewing angle detection, thereby improving the comprehensiveness and accuracy of the detection results.

[0032] The wiring mechanism 1 includes a support plate 16, a conductor rod 22, a slider 50 and a stop block 49. The support plate 16 is provided with two and fixedly connected to the inside of the installation cavity 9. The conductor rod 22 is rotatably connected between the two support plates 16, and a slide groove 51 is provided on each support plate 16. A guide rod 2 52 is provided inside the slide groove 51. The slider 50 is slidably sleeved on the guide rod 2 52. The end of the slider 50 away from the support plate 16 is fixedly connected to a sleeve 47. The inside of the sleeve 47 is slidably connected to a slide rod 48. The slide rod 4 A spring 2 is fixedly connected between 8 and the sleeve 47, and a stop block 49 is embedded in the end of the slide rod 48 away from the sleeve 47, and the stop block 49 abuts against the wire 7. When the first detector 3 drives the wire 7 to move, the two stops 49 clamp one end of the wire 7 and fix it. Under the action of gravity of the sleeve 47, the slide rod 48, the stop block 49 and other parts, one end of the wire 7 is always pulled, so that the wire 7 is straightened and the exposed length of the wire 7 is shortened, the wiring is more regular, and the normal operation of the device is not affected.

[0033] The second wiring mechanism includes a conductor rod 40, a spring box 46, a spring shaft 45 and a guide roller 44. The conductor rod 40 is rotatably connected in the wire groove 23, and a ring groove 41 is provided on the conductor rod 40. The ring groove 41 can limit the wire 6 to ensure that the second detector 4 can always maintain a certain distance from the guide groove 10 when moving in front of the first detector 3, thereby avoiding the influence of the wire 6 on the movement of the first detector 3.

[0034] A connecting frame 18 is fixedly connected to the side wall of the installation cavity 9, and a rotating shaft 42 is rotatably connected to the inner wall of the connecting frame 18. A guide roller 1 43 is fixedly connected to the middle position of the rotating shaft 42. A spring box 46 is also fixedly connected to the inner wall of the connecting frame 18 on one side of the rotating shaft 42. A spring is installed in the spring box 46. One end of the spring shaft 45 is rotatably matched with the spring box 46 and penetrates the spring box 46 to be connected to the spring. A guide roller 2 44 is fixedly connected to the spring shaft 45. The routing mechanism 2 does not use gravity to tighten the wire 2 6, because the distance moved by the second detector 4 is long, the length of the wire 2 6 is also long (the length shown in the figure is not the actual length of the wire 2 6), and the height of the installation cavity 9 is limited, and it cannot meet the requirement of using gravity to tighten the wire 2 6 over a long distance. When the second detector 4 moves to the right to drive the wire 2 6 to move, when the wire 2 6 passes through the guide roller 1 43 and the guide roller 2 44, the wire 2 6 overcomes the resistance of the spring, drives the guide roller 2 44 to rotate, and tightens the spring at the same time, so that the wire 2 6 can be tightened to ensure its regular routing. When the second detector 4 moves to the left, it drives the wire 2 6 to move. At this time, the spring drives the spring shaft 45 to reverse, and drives the wire 2 6 into the installation cavity 9 through the rotation of the guide roller 2 44.

[0035] Working principle: place the display screen on the fixing table 2, the plastic frame at the bottom of the display screen is stuck in the placement groove 13, start the motor 11, the rotation of the motor 11 drives the threaded rod 37 to rotate, the threaded rod 37 rotates and drives the clamping plate 35 to approach the display screen, the clamping plate 35 drives the clamping block 39 to fix the edge of the display, the motor 21 can drive the threaded rod 2 56 to rotate, the threaded rod 2 56 drives the mounting seat 155 to slide in the guide groove 10, so as to adjust the position of the first detector 3, and at the same time, the two blocks 49 clamp one end of the fixed wire 7, and the wire 7 is always tightened under the gravity of the blocks 49, the sleeve 47 and other parts, so as to fix the wire 7. The first detector 3 is arranged in a regular manner to avoid entanglement and knotting when following the movement of the first detector 3. At the same time, the exposed length of the connecting wire can be shortened to the greatest extent to avoid interfering with the normal operation of the device. When the motor 34 rotates, it drives the connecting rod 20 to swing, the connecting rod 20 drives the connecting rod 2 33 to swing, the connecting rod 2 33 drives the ring 19 to swing, the ring 19 drives the lower rod 30 and the upper rod 27 to move along the guide groove 2 5, so that the upper rod 27 drives the mounting seat 2 17 to move, and the mounting seat 2 17 drives the second detector 4 to move to different angles of the display screen for viewing angle detection. At the same time, under the action of the spring, the wire 2 6 is tightened by the guide roller 1 43 and the guide roller 2 44.
