Description

Technical Field

[0001] The present invention relates to the technical field of intelligent desks and chairs, and in particular to an intelligent desk and chair with a sitting posture correction function. Background Art

[0002] Elementary school students are in a critical stage of physical development, and their bones, muscles, and nervous systems are not yet fully mature. Long-term use of traditional desks and chairs or maintaining poor sitting posture may cause a series of health problems. Desks and chairs are the core equipment in students' learning scenes, and their design directly affects learning efficiency, physical health, and long-term development. Poor desk and chair design may cause the following health problems: 1. Scoliosis: When the chair back is unsupported or the table height does not match, children will twist their spine to maintain balance, which will lead to scoliosis in the long run. Scoliosis is directly related to the poor adaptability of desks and chairs. 2. Aggravated myopia: The height of the desktop is too low, resulting in the eyes being too close. 3. Muscle strain: Insufficient seat depth causes the thighs to hang in the air, and pressure is concentrated on the ischial tuberosity; excessive seat depth compresses the popliteal blood vessels.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0032] like Figures 1-9 The intelligent desk and chair with a posture correction function shown in the figure includes a seat cushion 1 and a desk 2. The seat cushion 1 is mounted with a movable rod 6 via a telescopic mechanism, and the movable rod 6 is mounted with a gear 8 via a gear shift mechanism. The seat cushion 1 is mounted with a transverse seat 18 via a transverse mechanism, and the transverse seat 18 is mounted with a backrest 24 via a vertical mechanism. A fixed pillow 25 is fixedly mounted on the upper surface of the backrest 24. The fixed pillow 25 is mounted with a wide fixing belt 28 via a head binding mechanism, and the fixed pillow 25 is mounted with a hook 33 via a pull belt mechanism.

[0033] The head binding mechanism includes a hook-surface Velcro 29 fixedly installed on the outside of the short side of the wide fixing belt 28, and a fleece-surface Velcro 30 fixedly installed on the inside of the long side of the wide fixing belt 28 to fix the head.

[0034] The telescopic mechanism includes two moving rods 6 fixedly mounted on the lower surface of the seat cushion 1. A fixed rod 5 is movably sleeved on the outer surface of each moving rod 6, so that the moving rod 6 can drive the seat cushion 1 to move up and down. A support member 14 is fixedly mounted on the lower surface of each fixed rod 5 to provide upper support force. A connecting beam 4 is fixedly mounted between the two support members 14 to increase the firmness of the two support members 14.

[0035] The gear shift mechanism includes a rack 7 fixedly mounted on the front side of the inner surface of each mobile rod 6, and a gear 8 is movably mounted on the inner surface of each mobile rod 6, and the gear 8 is meshed with the rack 7. A movable groove 37 is respectively opened on both sides of each mobile rod 6, and the movable groove 37 is opened on both sides of the rack 7. A synchronous rotating rod 12 is fixedly mounted on the opposite surface of the two gears 8, and the synchronous rotating rod 12 is movable through the fixed rod 5 and the movable groove 37. A hollow rotating rod 9 is fixedly mounted on the other side of one of the gears 8, and the hollow rotating rod 9 is movable through the fixed rod 5 and the movable groove 37. The inner surface of the hollow rotating rod 9 is movably mounted with a meshing hexagonal column 10, and a first rotating handle 11 is fixedly mounted on the outside of the hexagonal column 10. When the first rotating handle 11 is rotated, the hexagonal column 10 drives the hollow rotating rod 9 and the gear 8 to rotate, and the connected synchronous rotating rod 12 drives the other gear 8 to rotate synchronously. Since a movable groove 37 is provided inside the movable rod 6, the synchronous rotating rod 12 will not hinder the movable rod 6 from moving up and down. Since the gear 8 is meshed with the rack 7, when the gear 8 rotates, the two movable rods 6 will move up and down synchronously, thereby adjusting the up and down movement of the seat cushion 1.

[0036] A fixing screw 13 is movably passed through the rear surface of the fixing rod 5, and the fixing screw 13 is threadedly matched with the fixing rod 5, and the fixing screw 13 is movably installed on the rear side of the moving rod 6. By rotating the fixing screw 13 in the two fixing rods 5 counterclockwise, the moving rod 6 is fixed to prevent the seat cushion 1 from moving downward due to gravity.

[0037] The transverse movement mechanism includes a bottom connecting member 15 fixedly mounted on the lower surface of the seat cushion 1, a first screw rod 16 is movably mounted on the inner surface of the bottom connecting member 15, and the first screw rod 16 is rotatably connected to the bottom connecting member 15, a first guide rod 17 is movably mounted on the inner surface of the bottom connecting member 15, and the first guide rod 17 movably passes through the front surface of the bottom connecting member 15, and a transverse movement seat 18 is movably mounted on the outer surface of the first screw rod 16, and the transverse movement seat 18 is threadedly matched with the first screw rod 16, and the first guide rod 17 is fixedly mounted on the front surface of the transverse movement seat 18, and the first screw rod 16 is screwed to the bottom connecting member 15. The first guide rod 17 is installed on one side of the transverse seat 18, and a second rotating handle 19 is fixedly installed at the rear end of the first screw rod 16. Rotating the second rotating handle 19 drives the first screw rod 16 to rotate, and since the position of the bottom connecting member 15 is relatively fixed, the transverse seat 18 threadedly engaged with the first screw rod 16 will move back and forth, and since the first guide rod 17 fixedly installed on the front surface of the transverse seat 18 movably passes through the bottom connecting member 15, the transverse seat 18 will not flip over during the forward and backward movement, so that the position of the backrest 24 can fit the back better.

[0038] The vertical movement mechanism includes a second screw rod 20 movably mounted on the inner surface of the transverse movement seat 18, and the second screw rod 20 is threadedly matched with the transverse movement seat 18, a second guide rod 21 is fixedly mounted on the upper surface of the transverse movement seat 18, and a third rotating handle 22 is fixedly mounted on the lower surface of the second screw rod 20, a vertical movement seat 23 is sleeved on the outer surface of the upper end of the second screw rod 20, and the vertical movement seat 23 is rotatably connected to the second screw rod 20, and the second guide rod 21 movably passes through the upper surface of the vertical movement seat 23, and the second screw rod 20 and the second guide rod 21 are mounted on the other side of the transverse movement seat 18, and the backrest 24 It is fixedly installed on the front surface of the vertical shift seat 23, and rotating the third rotating handle 22 drives the second screw rod 20 to rotate. Since the vertical position of the transverse shift seat 18 is relatively fixed, the vertical shift seat 23 rotatably connected to the second screw rod 20 will move up and down, and since the second guide rod 21 fixedly installed on the upper surface of the transverse shift seat 18 movably penetrates the vertical shift seat 23, the vertical shift seat 23 will not flip over during the up and down movement. After vertical adjustment, the backrest 24 can be in the center position of the back, and the backrest 24 will fit the back more closely, thereby achieving the purpose of correcting the sitting posture.

[0039] The head binding mechanism also includes two fixing holes 26 opened in the fixed pillow 25, and a fixing column 27 is fixedly installed on the inner surface of each fixing hole 26, and a wide fixing belt 28 is fixedly installed on the outer surface of the fixing column 27 on one side. The short side of the wide fixing belt 28 fixed on the outside of the fixing column 27 faces forward and the long side faces backward, passing through the other fixing hole 26 to the front, so that the user's head is raised and the neck is close to the fixed pillow 25. First, the short side with the hook-surface Velcro 29 is placed in front of the forehead, and then the long side with the fleece-surface Velcro 30 is tightened so that the long side overlaps the short side, and the hook-surface Velcro 29 is fit with the fleece-surface Velcro 30. The widening of the fixing belt can increase the force-bearing surface, which can not only fix the head and correct the sitting posture, but also adapt to different head circumferences.

[0040] The drawstring mechanism includes a positioning member 31 fixedly mounted on one side of the inner surface of the fixed pillow 25, a C-shaped member 32 movably mounted on the inner surface of the positioning member 31, a hook 33 fixedly mounted on the upper end of the C-shaped member 32, and an L-shaped plate 34 fixedly mounted on the lower end of the C-shaped member 32, a fixing member 35 movably mounted on the inner surface of the L-shaped plate 34, and the fixing member 35 movably passes through the rear surface of the fixed pillow 25, and a placement hole 36 is provided on the upper surface of the L-shaped plate 34. When the user ties a hairstyle such as a ponytail at the back of the head, the L-shaped plate 34 is pressed downward so that the hook 33 pulls down the wide fixing strap 28 at the back to avoid damaging the hairstyle. The L-shaped plate 34 and the hook 33 are fixed by the fixing member 35. When not in use, the fixing member 35 is placed in the placement hole 36 to prevent loss.

[0041] An infrared sensor 3 is fixedly installed in the desk 2, and the infrared sensor 3 is used to intelligently detect whether the user is studying in front of the desk 2.

[0042] During use, in order to adapt to the growing user, the seat cushion 1 and the backrest 24 need to be adjusted. First, adjust the seat cushion 1 and rotate the first rotating handle 11 clockwise to make the hexagonal column 10 drive the hollow rotating rod 9 and the gear 8 to rotate clockwise. The connected synchronous rotating rod 12 drives the other gear 8 to rotate synchronously. Since the movable groove 37 is provided inside the movable rod 6, the synchronous rotating rod 12 will not hinder the movable rod 6 from moving up and down. Since the gear 8 is engaged with the rack 7, when the gear 8 rotates clockwise, the two movable rods 6 will move up synchronously, thereby adjusting the seat cushion 1 to move upward. The user sits down gently. When the knee joint is parallel to the ground, it is the best position. By rotating the fixing screws 13 in the two fixing rods 5 counterclockwise, the movable rod 6 is fixed to prevent the seat cushion 1 from moving downward due to gravity. Then adjust the backrest 24 and rotate the second rotating handle 19 clockwise. The first screw rod 16 is driven to rotate clockwise, and since the position of the bottom connecting piece 15 is relatively fixed, the transverse seat 18 threadedly matched with the first screw rod 16 will move backward, and since the first guide rod 17 fixedly installed on the front surface of the transverse seat 18 movably penetrates the bottom connecting piece 15, the transverse seat 18 will not flip over during the forward and backward movement. The third rotating handle 22 is rotated counterclockwise to drive the second screw rod 20 to rotate counterclockwise, and since the vertical position of the transverse seat 18 is relatively fixed, the vertical seat 23 rotatably connected with the second screw rod 20 will move upward, and since the second guide rod 21 fixedly installed on the upper surface of the transverse seat 18 movably penetrates the vertical seat 23, the vertical seat 23 will not flip over during the up and down movement. The backrest 24 after horizontal and vertical adjustment can not only be in the center position of the back, but also the backrest 24 will fit the back more closely, achieving the purpose of correcting the sitting posture.

[0043] When in daily use, the user is sitting on the correction chair and moves the wide fixing strap 28 fixed on the outside of the fixing column 27 with the short side facing forward and the long side facing backward through another fixing hole 26 to the front, so that the user raises his head and neck close to the fixing pillow 25, first places the short side with the hook-surface Velcro 29 in front of the forehead, and then tightens the long side with the fur-surface Velcro 30 to overlap with the short side, so that the hook-surface Velcro 29 fits with the fur-surface Velcro 30. The widening of the fixing strap can increase the force-bearing surface, which can not only fix the head to correct the sitting posture, but also adapt to different head circumferences. When the user has a ponytail or other hairstyle at the back, press the L-shaped plate 34 downward so that the hook 33 pulls down the wide fixing strap 28 at the back to avoid conflict with the hairstyle. The L-shaped plate 34 and the hook 33 are fixed by the fixing piece 35. When not in use, the fixing piece 35 is placed in the placement hole 36 to prevent it from being lost.
