Description

Technical Field

[0001] The invention relates to the technical field of gravity sensing seats, in particular to a gravity sensing seat with adjustable sensing position. Background Art

[0002] With the improvement of living standards, people are paying more and more attention to improving the quality of life. Chairs are one of the indispensable items in people's daily lives. Moreover, with the improvement of technology, various types of chairs are emerging. Office workers and students are often called sedentary people, but sitting for a long time will cause the waist to be under stress all the time, resulting in waist compression and prone to waist diseases, which will affect physical health.

[0003] Existing gravity-sensing chairs only provide support for users and do not have the function of monitoring and adjusting the user's sitting posture. Incorrect sitting posture of the user will cause the chair to lack support for the waist, and sitting for a long time will affect the user's health. In order to improve comfort, the existing gravity-sensing chairs have relatively large backrest designs. When the chair is not used for a long time and needs to be stored, the backrest does not have the function of telescopic adjustment, so the storage of the chair will take up a large space.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A gravity sensing chair with adjustable sensing position, comprising a base and a lower plate:

[0008] The adjusting assembly comprises two slide rails symmetrically mounted on the upper surface of the lower plate, the slide rails are slidably connected to a slide seat, and one end of the two slide seats away from the slide rails is commonly fixedly connected to the upper plate, and two connecting plates are symmetrically mounted on the upper surface of the upper plate, the connecting plate is provided with a movable groove, and an L-shaped plate is slidably connected in the movable groove, and a chair back is fixedly connected between the two L-shaped plates, and one end of the connecting plate away from the upper plate is fixedly connected to the vertical plate, and one end of the vertical plate close to the connecting plate is fixedly connected to the support plate, and the end of the support plate away from the chair back is rotatably connected to the rotating plate, and the vertical plate is provided with a lifting groove, and a dial plate is slidably connected in the lifting groove, and the two ends of the rotating plate are slidably connected to the dial plate and the L-shaped plate respectively;

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] refer to Figure 1-Figure 7 , a gravity-sensing chair with adjustable sensing position shown in the figure includes a base 2 and a lower plate 7, an adjustment component including two slide rails 13 symmetrically mounted on the upper surface of the lower plate 7, a slide seat 12 is slidably connected in the slide rail 13, and the two slide seats 12 are fixedly connected to the upper plate 6 at one end away from the slide rail 13, and two connecting plates 1 are symmetrically mounted on the upper surface of the upper plate 6, a movable groove 14 is opened on the connecting plate 1, an L-shaped plate 15 is slidably connected in the movable groove 14, a chair back 4 is fixedly connected between the two L-shaped plates 15, an end of the connecting plate 1 away from the upper plate 6 is fixedly connected to a vertical plate 16, an end of the vertical plate 16 close to the connecting plate 1 is fixedly connected to a support plate 21, and the support plate 21 is away from the chair back 4 One end is rotatably connected to a rotating plate 20, a lifting groove 18 is provided on the vertical plate 16, and a paddle plate 19 is slidably connected in the lifting groove 18. Both ends of the rotating plate 20 are slidably connected to the paddle plate 19 and the L-shaped plate 15 respectively. A mounting groove 41 is provided on the base 2, and a roller ring 39 is fixedly connected in the mounting groove 41. The inner wall of the roller ring 39 is fixedly connected to the lifting rod 3, and the outer wall of the lifting rod 3 is fixedly connected to the spur gear 37. The end of the base 2 close to the lower plate 7 is fixedly connected to a protective cover 40, and the end of the protective cover 40 away from the base 2 is fixedly connected to a rotating motor 10, and the end of the connecting plate 1 away from the upper plate 6 is fixedly connected to an armrest 8, and the end of the armrest 8 close to the connecting plate 1 is fixedly connected to a controller 9.

[0032] In order to reduce the space occupied by the seat storage, the present invention is provided with an adjustment component, which lifts the seat 5 through the spring under the seat 5, and the rotating plate 20 moves up synchronously with the seat 5. The L-shaped plate 15 connected to the other end of the rotating plate 20 moves downward along the movable groove 14 to lower the height of the chair back 4. The controller 9 adjusts the height of the lifting rod 3, and the seat height is lowered by the extension and retraction of the chair back 4 and the lifting rod 3. The space occupied by the seat is reduced, making it easier to store.

[0033] Specifically, first, when the gravity-sensing chair needs to be stored, the user stands up from the seat 5, and the seat 5 is lifted up by the rebound force of the springs symmetrically installed on the upper surface of the upper plate 6, and the seat 5 moves upward along the lifting groove 18 on the vertical plate 16. Since the dial plate 19 is fixedly connected to the seat 5, the dial plate 19 moves up synchronously to cause the rotating plate 20 to rotate on the support plate 21. It is worth noting that the distance between the support plate 21 and the dial plate 19 is much smaller than the distance between the support plate 21 and the L-shaped plate 15. At this time, the L-shaped plate 15 moves along the moving groove 14 under the activation of the rotating plate 20. At this time, the height of the chair back 4 gradually decreases. When the dial plate 19 moves to the highest point of the lifting groove 18, the chair back 4 is lowered to the lowest point. At the same time, the controller 9 on the armrest 8 automatically lowers the height of the lifting rod 3, so that the overall height of the seat is reduced, the space occupancy is reduced, and it is more convenient to store.

[0034] Secondly, when the seat needs to be used, the user sits on the seat 5, and the seat 5 is forced to move down along the lifting slot 18, and the dial plate 19 moves down synchronously with the seat 5. The downward movement of the dial plate 19 causes the rotating plate 20 to rotate, and the L-shaped plate 15 and the seat back 4 move in opposite directions along the moving slot 14. At the same time, the spring under the seat 5 is also in a gradually compressed state. When the seat 5 moves down to the lowest point, the seat back 4 moves to the highest point, and the height of the lifting rod 3 is automatically raised by the controller 9 to complete the height adjustment of the seat. When the seat needs to be rotated to adjust the seat angle, the angle adjustment of the seat can be achieved by controlling the rotation of the rotating motor 10, and the lifting system and rotation system of the seat are designed separately, and the height adjustment will not interfere with the angle adjustment, making the adjustment of the seat more flexible and convenient, and the roller 11 arranged under the base 2 is more convenient for storage and movement.

[0035] refer to Figure 1-Figure 7, auxiliary components, including a telescopic slot 22 opened on the connecting plate 1, a telescopic rod 24 is slidably connected in the telescopic slot 22, and the two telescopic rods 24 are fixedly connected to the back plate 23 at one end away from the telescopic slot 22, and the seat 5 is fixedly connected between the two dial plates 19. A connecting slot 27 is opened on the upper plate 6, and a slider 26 is slidably connected in the connecting slot 27. Both ends of the slider 26 are fixedly connected to the telescopic rod 24, and the seat 5 is rotatably connected to the end near the lower plate 7 with a hinged plate 25. The seat 5 and the slider 26 are rotatably connected through the hinged plate 25. The lower plate 7 is fixedly connected to the air cylinder 17, and the compression plate 34 is slidably connected in the air cylinder 17. The compression plate The end of 34 close to the seat 5 is fixedly connected to the push rod 33, the end of the air cylinder 17 away from the push rod 33 is fixedly connected to the fixing frame 35, the fixing frame 35 is slidably connected to the push rod 36, the end of the push rod 36 away from the compression plate 34 is fixedly connected to the blocking block 38, the back plate 23 is fixedly connected to the shell 28, the shell 28 is slidably connected to the spline rod 29, the end of the spline rod 29 close to the back plate 23 is fixedly connected to the arc plate 30, the end of the arc plate 30 away from the shell 28 is fixedly connected to the airbag 31, the end of the upper plate 6 close to the lower plate 7 is fixedly connected to the toothed plate 32, and the end of the base 2 away from the protective cover 40 is rotatably connected to a plurality of rollers 11.

[0036] In order to monitor the user's sitting posture, the present invention is provided with an auxiliary component, which drives the upper plate 6 to move along the slide rail 13 through the tooth plate 32, and then adjusts the position of the upper plate 6 relative to the gravity sensor, and automatically records the gravity parameters of the user under the correct sitting posture. When the information obtained by the gravity sensor deviates greatly from the preset value, it automatically reminds the user that the sitting posture is incorrect, and the seat 5 is forced to move downward, pushing the airbag 31 on the backrest 23 to fit the user's waist and automatically inflate to support the waist, thereby avoiding damage to the waist due to long-term stress.

[0037] Specifically, first, when the chair is in use, the seat 5 is pressed down, the backrest 4 moves up along the moving groove 14, and the slider 26 moves along the connecting groove 27 under the push of the hinge plate 25. Since the two ends of the slider 26 are fixedly connected to the telescopic rod 24, the telescopic rod 24 moves in the same direction as the slider 26 along the telescopic groove 22. At the same time, the push rod 33 moves downward to push the compression plate 34 to move on the inner wall of the air cylinder 17. At this time, the air cylinder 17 is in the exhaust state. It is worth noting that the air cylinder 17 is not fixedly connected to the upper plate 6. At the same time, the tooth plate 3 The upper plate 6 moves along the slide rail 13, adjusting the position of the gravity sensor on the lower plate 7. Simultaneously, the gravity sensor automatically records the user's gravity parameter information. When the backrest 4 rises to its highest point, the backrest 23 and backrest 4 also move below the backrest 4. When the seat 5 descends to its lowest point, the seat 5 stops moving, and the gas in the cylinder 17 is fed into the airbag 31 through the air tube, supporting the user's waist. The gravity sensor information is also synchronously transmitted to the central processing unit (CPU). The CPU 13 is an AMD FX-8000 processor, a very large-scale integrated circuit (VLSI) that serves as the computing and control core of a computer. The gravity sensor is a high-precision miniature pressure sensor, the JLBU-1. It uses an elastic sensitive element to create a cantilevered displacement device. It uses an energy storage spring, also made of an elastic sensitive element, to drive electrical contacts, completing the conversion from gravity changes to electrical signals. The alarm device is a vibration, sound, or light alarm. When the information obtained by the gravity sensor deviates significantly from the preset value, the user is alerted to an incorrect sitting posture.

[0038] Secondly, when the seat is not in use, the seat 5 moves upward under the support of the rebound force of the spring on the upper plate 6. At this time, the hinged plate 25 pulls the slider 26 to move in the opposite direction along the connecting groove 27, and pushes the back plate 23 in the opposite direction along the telescopic groove 22 to avoid affecting the downward movement and storage of the backrest 4. It is worth noting that the seat 5 and the backrest 4 are both provided with memory sponge at the contact end with the user to improve the comfort of the seat. As the seat 5 moves upward, the air cylinder 17 is in the intake state, and the gas in the airbag 31 flows back into the air cylinder 17 through the trachea. At the same time, the push rod 36 moves upward along the fixing frame 35 so that the block 38 opens the air inlet on the air cylinder 17 to intake air. When the dial plate 19 rises to the highest point of the lifting slot 18, the back plate 23 and the backrest 4 return to their original positions.

[0039] Working principle of the present invention: When the gravity-sensing chair needs to be stored, the user stands up from the seat 5, and the seat 5 is lifted up under the rebound force of the springs symmetrically installed on the upper surface of the upper plate 6. At this time, the hinged plate 25 pulls the slider 26 to move in the opposite direction along the connecting groove 27, and pushes the back plate 23 in the opposite direction along the telescopic groove 22 to avoid affecting the downward movement and storage of the seat back 4. It is worth noting that the seat 5 and the seat back 4 are both provided with memory foam at the contact end with the user to improve the comfort of the seat. As the seat 5 moves upward, the air cylinder 17 is in the intake state, and the gas in the air bag 31 flows back into the air cylinder 17 through the trachea. At the same time, the push rod 36 moves upward along the fixing frame 35 to make the block 38 press the air cylinder 17 The air inlet opened on the upper part is opened to intake air. When the dial plate 19 rises to the highest point of the lifting slot 18, the backrest 23 and the chair back 4 return to their original positions, and the seat 5 moves upward along the lifting slot 18 on the vertical plate 16. Since the dial plate 19 is fixedly connected to the seat 5, the dial plate 19 moves upward synchronously to make the rotating plate 20 rotate on the support plate 21. At this time, the L-shaped plate 15 moves along the moving slot 14 under the toggle of the rotating plate 20. At this time, the height of the chair back 4 gradually decreases. When the dial plate 19 moves to the highest point of the lifting slot 18, the chair back 4 is lowered to the lowest point. At the same time, the controller 9 on the armrest 8 automatically lowers the height of the lifting rod 3, so that the overall height of the seat is reduced. When the seat needs to be used When the user sits on the seat 5, the seat 5 is forced to move down along the lifting groove 18, and the dial plate 19 moves down synchronously with the seat 5. The downward movement of the dial plate 19 causes the rotating plate 20 to rotate, and the L-shaped plate 15 and the chair back 4 move in opposite directions along the moving groove 14. The slider 26 moves along the connecting groove 27 under the push of the hinge plate 25. Since the two ends of the slider 26 are fixedly connected to the telescopic rod 24, the telescopic rod 24 moves in the same direction as the slider 26 along the telescopic groove 22. At the same time, the push rod 33 moves downward to push the compression plate 34 to move on the inner wall of the air cylinder 17. At this time, the air cylinder 17 is in the exhaust state. At the same time, the tooth plate 32 causes the upper plate 6 to move along the slide rail 13, adjusting the gravity sensor on the lower plate 7. The position of the device is determined, and the gravity sensor automatically records the user's gravity parameter information. When the chair back 4 rises to the highest point, the backrest 23 and the chair back 4 also move to the bottom of the chair back 4. When the seat 5 moves down to the lowest point, the seat 5 stops moving, and the gas in the air cylinder 17 is input into the airbag 31 through the trachea to support the user's waist. At the same time, the spring under the seat 5 is also in a gradually compressed state. When the seat 5 moves down to the lowest point, the chair back 4 moves to the highest point, and the height of the lifting rod 3 is automatically raised by the controller 9 to complete the height adjustment of the seat. When the seat needs to be rotated to adjust the seat angle, the angle adjustment of the seat can be achieved by controlling the rotation of the rotating motor 10.
