Description

[0001] The present invention relates to the technical field of displays, and particularly to an anti-fatigue computer display. Background Art

[0002] With the rapid development of information technology, computers have become an indispensable tool in people's work, study, and life. During the long-term use of a computer, as a key interface for human-computer interaction, the performance and user experience of the display directly affect the physical health and work efficiency of the user. When watching the display screen for a long time, the eyes need to continuously focus and adjust, which is extremely easy to cause fatigue. Moreover, when the user maintains the same posture for a long time, it is easy to cause neck muscle strain.

[0003] Currently, in order to prevent the user from maintaining the same posture for a long time and causing eye and neck fatigue, it is necessary to adjust the height of the display regularly to change the viewing distance of the user and enable the user to improve neck fatigue by tilting the head up and down. However, when adjusting the height of the display in the prior art, the display cannot always face the user directly, which will affect the viewing effect of the user. In addition, the screen of the display is easily contaminated after long-term use, and the cleaning of the display in the prior art is rather troublesome, which will affect the work efficiency of the user.

Detailed Embodiments

[0021] The following will explain each embodiment of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0022] A computer anti-fatigue monitor, as shown in the appendix Figure 1-10 As shown, it includes a monitor main body 1 and a base 2. A support 3 is fixedly connected to the upper surface of the base 2. A lifting seat 4 is slidably connected inside the support 3. A first rotating shaft 5 is rotatably installed inside the lifting seat 4. A connecting plate 6 is fixedly connected to the outer surface of the first rotating shaft 5. One end of the connecting plate 6 away from the first rotating shaft 5 is fixedly connected to the back of the monitor main body 1. Both the base 2 and the support 3 are hollow shells with open fronts, and a front cover for closing the openings is installed on the fronts of the base 2 and the support 3.

[0023] A driving mechanism for driving the lifting seat 4 to move up and down reciprocally is arranged inside the support 3. The driving mechanism includes a driving shaft 15 and a second rotating shaft 16 rotatably installed inside the support 3. Bevel gears 17 are fixedly connected to the outer surfaces of the driving shaft 15 and the second rotating shaft 16. The two bevel gears 17 are meshed with each other. A motor 14 is installed on one side surface of the support 3. The output end of the motor 14 is fixedly connected to one end of the driving shaft 15. A first one-way bearing 18 is installed on the outer surface of the second rotating shaft 16. A first synchronous pulley 19 is installed on the outer surface of the first one-way bearing 18. A third one-way bearing is fixedly embedded inside the support 3. A third rotating shaft 20 is installed on the third one-way bearing. A second synchronous pulley 21 and a turntable 22 are fixedly connected to the outer surface of the third rotating shaft 20. The second synchronous pulley 21 and the first synchronous pulley 19 are connected by a first synchronous belt. The other end of the connecting rod 23 is rotatably installed on the back of the lifting seat 4. By setting the third one-way bearing, it can be ensured that the turntable 22 can only rotate upward, so that when the monitor main body 1 is not moved, the turntable 22 can be in a locked state. A machine cover for covering the motor 14 is installed on the left side surface of the support 3. When controlling the motor 14 to rotate forward, the driving shaft 15 can drive the bevel gear 17 and the second rotating shaft 16 to rotate. The rotation of the second rotating shaft 16 can drive the first one-way bearing 18 and the first synchronous pulley 19 to rotate as a whole. The rotation of the first synchronous pulley 19 can drive the second synchronous pulley 21 and the turntable 22 to rotate. Under the action of the connecting rod 23, the rotation of the turntable 22 can drive the lifting seat 4 to move up and down reciprocally. The movement of the lifting seat 4 can drive the monitor main body 1 to move correspondingly. When controlling the motor 14 to rotate in the reverse direction, the driving shaft 15 can drive the bevel gear 17 and the second rotating shaft 16 to rotate. At this time, the rotation of the second rotating shaft 16 will only drive the first one-way bearing 18 to rotate idly, so that the lifting seat 4 and the monitor main body 1 will still remain stationary.

[0024] An angle adjustment mechanism is provided on one side of the lifting seat 4. The angle adjustment mechanism includes an outer cover 24 fixedly connected to one side surface of the lifting seat 4. Two fourth rotating shafts 25 are rotatably installed inside the outer cover 24. First gears 26 are fixedly connected to the outer surfaces of the two fourth rotating shafts 25, and the two first gears 26 are meshed with each other. Third synchronous pulleys 27 are fixedly connected to the outer surfaces of one of the fourth rotating shafts 25 and the outer surface of the first rotating shaft 5. The two third synchronous pulleys 27 are connected by a second synchronous belt. A fifth rotating shaft 28 is rotatably installed inside the lifting seat 4. Fourth synchronous pulleys 29 are fixedly connected to the outer surfaces of the fifth rotating shaft 28 and the outer surface of the other first rotating shaft 5. The two fourth synchronous pulleys 29 are connected by a third synchronous belt. A second gear 30 is fixedly connected to the outer surface of the fifth rotating shaft 28. A toothed plate 31 is fixedly connected inside the support 3. The toothed plate 31 is meshed with the second gear 30. When the lifting seat 4 moves upward, the second gear 30 will rotate upward along the toothed plate 31. The upward rotation of the second gear 30 drives the fifth rotating shaft 28 and the fourth synchronous pulley 29 to rotate upward. Under the action of the two first gears 26, the third synchronous pulley 27 and the first rotating shaft 5 can be driven to rotate downward. The downward rotation of the first rotating shaft 5 can drive the display body 1 to rotate downward. Similarly, when the lifting seat 4 moves downward, the first rotating shaft 5 and the display body 1 can be driven to rotate upward. Thus, while the display body 1 moves up and down, the base 2 can always face the user directly, which can not only improve the fatigue of the user, but also ensure the viewing effect of the user.

[0025] A support plate 36 is fixedly connected inside the base 2. A reciprocating lead screw 43 is rotatably installed between the support plate 36 and the right side wall of the base 2. A threaded plate 7 is threadedly connected to the outer surface of the reciprocating lead screw 43, and the threaded plate 7 is slidably connected inside the base 2. The reciprocating lead screw 43 is connected to the drive mechanism through a linkage mechanism. The linkage mechanism includes a second one-way bearing 33 installed on the outer surface of the driving shaft 15. A fifth synchronous pulley 34 is installed on the second one-way bearing 33. A sixth rotating shaft 32 is rotatably installed inside the base 2. A sixth synchronous pulley 35 is fixedly connected to the outer surface of the sixth rotating shaft 32. The sixth synchronous pulley 35 and the fifth synchronous pulley 34 are connected by a fourth synchronous belt. When the motor 14 drives the driving shaft 15 to rotate forward, the driving shaft 15 only drives the second one-way bearing 33 to rotate idly. When the motor 14 drives the driving shaft 15 to rotate reversely, the driving shaft 15 drives the second one-way bearing 33 and the fifth synchronous pulley 34 to rotate as a whole. The rotation of the fifth synchronous pulley 34 drives the sixth synchronous pulley 35 and the sixth rotating shaft 32 to rotate.

[0026] A seventh rotating shaft 37 is rotatably installed between the left side wall of the support plate 36 and the base 2. One end of the seventh rotating shaft 37 is fixedly connected to one end of the reciprocating lead screw 43. Both the outer surface of the seventh rotating shaft 37 and the outer surface of the sixth rotating shaft 32 are fixedly connected with seventh synchronous pulleys 38. The two seventh synchronous pulleys 38 are connected by a fifth synchronous belt. Under the action of the seventh synchronous pulley 38, the rotation of the sixth rotating shaft 32 can drive the seventh rotating shaft 37 and the reciprocating lead screw 43 to rotate, and the rotation of the reciprocating lead screw 43 can drive the threaded plate 7 to reciprocate along the reciprocating lead screw 43.

[0027] A cleaning mechanism is arranged on the threaded plate 7. The cleaning mechanism includes a sliding plate 8 slidably connected inside the base 2. One side of the sliding plate 8 close to the threaded plate 7 is fixedly connected with a first spring 9. One end of the first spring 9 far away from the sliding plate 8 is fixedly connected with a first rectangular plate 10. One side of the first rectangular plate 10 far away from the first spring 9 is fixedly connected with a second rectangular plate 11. One side of the second rectangular plate 11 far away from the first rectangular plate 10 is fixedly connected with a moving rod 12. A cleaning cotton 13 is installed on the moving rod 12. The bottom of the sliding plate 8 is fixedly connected with a T-shaped slider. A T-shaped sliding groove adapted to the T-shaped slider is opened inside the base 2. When the display main body 1 is not cleaned, that is, in the initial state, the first spring 9 is in a stretched state.

[0028] One side of the threaded plate 7 close to the slide plate 8 is fixedly connected with a first wedge block 39 and a third rectangular plate 40. One side of the second rectangular plate 11 close to the threaded plate 7 is fixedly connected with a second wedge block 44 adapted to the first wedge block 39. One side of the third rectangular plate 40 away from the threaded plate 7 is fixedly connected with a right-angle rod 41. The upper surface of the right-angle rod 41 is fixedly connected with a pulling block 42, and the pulling block 42 is located on the left side of the first rectangular plate 10. The cleaning mechanism further includes a rectangular cylinder 47 fixedly connected inside the base 2. One side of the rectangular cylinder 47 close to the second rectangular plate 11 is fixedly connected with a second spring 48. One end of the second spring 48 away from the rectangular cylinder 47 is fixedly connected with a fourth wedge block 46. One side of the second rectangular plate 11 close to the rectangular cylinder 47 is fixedly connected with a third wedge block 45 adapted to the fourth wedge block 46. One side of the fourth wedge block 46 away from the second rectangular plate 11 is fixedly connected with a guide post 49, and the other end of the guide post 49 is inserted into the inside of the rectangular cylinder 47. In the initial state, the first wedge block 39 is located behind the second wedge block 44 and blocks the second wedge block 44. The fourth wedge block 46 is located behind the third wedge block 45 and blocks the third wedge block 45. When cleaning the display body 1, the threaded plate 7 will first drive the first wedge block 39 and the pulling block 42 to move to the right. When the pulling block 42 moves to contact with the first rectangular plate 10, the first wedge block 39 will no longer block the second wedge block 44, and the fourth wedge block 46 still blocks the third wedge block 45. Then the threaded plate 7 continues to move and can drive the first wedge block 39, the first rectangular plate 10, the second rectangular plate 11, the cleaning cotton 13 and the third wedge block 45 to move to the right. When the cleaning cotton 13 moves to the front of the display body 1, the fourth wedge block 46 no longer blocks the third wedge block 45. At this time, under the action of the first spring 9, the second rectangular plate 11, the second wedge block 44, the third wedge block 45 and the cleaning cotton 13 will move towards the display body 1, so that the cleaning cotton 13 will be close to the display body 1. At this time, continue to control the threaded plate 7 to move to make the cleaning cotton 13 move along the display body 1 to clean the display body 1. After the slide plate 8 and the second rectangular plate 11 move to the left to the maximum extent after cleaning, the threaded plate 7 continues to move to the left, and the first wedge block 39 can squeeze the second wedge block 44 to move forward. The forward movement of the second wedge block 44 can drive the second rectangular plate 11, the support 3 and the third wedge block 45 to move forward and stretch the first spring 9. The forward movement of the third wedge block 45 can squeeze the fourth wedge block 46 to move to the left and compress the second spring 48. When the threaded plate 7 moves to the left to the maximum extent, the third wedge block 45 will move in front of the fourth wedge block 46. Thus, under the action of the second spring 48, the fourth wedge block 46 will move to the right to reset, and then it will return to the initial state.

[0029] Working principle: When the user watches the display main body 1 for a long time, the motor 14 is started, and the motor 14 drives the driving shaft 15 to rotate forward. The forward rotation of the driving shaft 15 can drive the bevel gear 17 and the second rotating shaft 16 to rotate. The rotation of the second rotating shaft 16 can drive the first one-way bearing 18 and the first synchronous wheel 19 to rotate as a whole. The rotation of the first synchronous wheel 19 can drive the second synchronous wheel 21 and the turntable 22 to rotate. Under the action of the connecting rod 23, the rotation of the turntable 22 can drive the lifting seat 4 and the display main body 1 to move up and down reciprocally. When the lifting seat 4 moves upward, the second gear 30 will rotate upward along the toothed plate 31. The upward rotation of the second gear 30 drives the fifth rotating shaft 28 and the fourth synchronous wheel 29 to rotate upward. Under the action of the two first gears 26, the third synchronous wheel 27 and the first rotating shaft 5 can be driven to rotate downward. The downward rotation of the first rotating shaft 5 can drive the display main body 1 to rotate downward. Similarly, when the lifting seat 4 moves downward, the first rotating shaft 5 and the display main body 1 can be driven to rotate upward. Thus, while the display main body 1 moves up and down, the base 2 can always face the user directly, which can not only improve the fatigue of the user, but also ensure the viewing effect of the user.

[0030] In the initial state, the first wedge block 39 is located behind the second wedge block 44 and blocks the second wedge block 44. The fourth wedge block 46 is located behind the third wedge block 45 and blocks the third wedge block 45. When it is necessary to clean the display body 1, the motor 14 is started, and the motor 14 drives the driving shaft 15 to rotate in the reverse direction. The reverse rotation of the driving shaft 15 can drive the second one-way bearing 33 and the fifth synchronous pulley 34 to rotate as a whole. The rotation of the fifth synchronous pulley 34 can drive the sixth synchronous pulley 35 and the sixth rotating shaft 32 to rotate. The rotation of the sixth rotating shaft 32 can drive the seventh rotating shaft 37 and the reciprocating lead screw 43 to rotate. The rotation of the reciprocating lead screw 43 can drive the threaded plate 7 to move reciprocally along the reciprocating lead screw 43. The threaded plate 7 will first drive the first wedge block 39 and the pulling block 42 to move to the right. When the pulling block 42 moves to contact the first rectangular plate 10, the first wedge block 39 will no longer block the second wedge block 44, and the fourth wedge block 46 still blocks the third wedge block 45. Then the threaded plate 7 continues to move and can drive the first wedge block 39, the first rectangular plate 10, the second rectangular plate 11, the cleaning cotton 13 and the third wedge block 45 to move to the right. When the cleaning cotton 13 moves to the front of the display body 1, the fourth wedge block 46 no longer blocks the third wedge block 45. At this time, under the action of the first spring 9, the second rectangular plate 11, the second wedge block 44, the third wedge block 45 and the cleaning cotton 13 will move towards the display body 1, so that the cleaning cotton 13 will be close to the display body 1. At this time, continue to control the threaded plate 7 to move to make the cleaning cotton 13 move along the display body 1 to clean the display body 1. During the cleaning of the display screen body 1, the first spring 9 is in a slightly stretched state. Thus, when the threaded plate 7 moves to the left, the first wedge block 39 will push the second wedge block 44, the second rectangular plate 11 and the cleaning cotton 13 to move to the left. After the cleaning is completed and the slide plate 8 and the second rectangular plate 11 move to the left to the maximum extent, as shown in the attachment Figure 10 As shown, when the threaded plate 7 continues to move to the left, the first wedge block 39 can squeeze the second wedge block 44 to move forward. The forward movement of the second wedge block 44 can drive the second rectangular plate 11, the support 3 and the third wedge block 45 to move forward and stretch the first spring 9. The forward movement of the third wedge block 45 can squeeze the fourth wedge block 46 to move to the left and compress the second spring 48. When the threaded plate 7 moves to the left to the maximum extent, the third wedge block 45 will move in front of the fourth wedge block 46. Thus, under the action of the second spring 48, the fourth wedge block 46 will move to the right to reset, and at this time, it will return to the initial state.
