[0031] Among them, the base 15 is connected to the wall, the support feet 34 are fixed to the floor, a wooden board 12 is embedded in the upper part of the plastic seat board 11, and the wooden board 12 provides contact support for the human body. One side of the plastic seat board 11 is movably connected to the base 15 through a hinge 13 and a hinge connecting member 14. The movable plastic seat board 11 is convenient for rotation. Inside the plastic seat board 11, a driving gear 25 is driven by a motor 22, and then a lead screw 24 is driven. The lead screw 24 drives a moving member 26 connected by threads through the forward and reverse rotation of the motor 22. The moving member 26 drives a connecting rod 33 to move horizontally in the middle of the plastic seat board 11, and then drives a plastic support plate 32 to move horizontally at the bottom of the plastic seat board 11. The control assembly 4 conducts overall control. During the horizontal movement of the plastic seat board 11, the support rod 31 is driven to move, so that the plastic seat board 11 is folded or laid flat.

At the same time, the plastic support plate 32 abuts against the arc-shaped abutting groove on the bottom side of the plastic seat board 11 to provide stable support for the plastic seat board 11. A stable triangular support is formed by the plastic seat board 11, the support rod 31 and the wall. When folding is required, the motor 22 is reversely rotated through the control assembly 4, so that the moving member 26 moves horizontally in the reverse direction, driving the plastic support plate 32 to move, and then the plastic seat board 11 is folded vertically upwards. After folding is completed, the lead screw 24 limits the moving member 26. The plastic seat board 11 is folded and unfolded through the power assembly 2 and the support assembly 3.

[0032] Please refer to Figures 1-7 The power assembly 2 further includes a set of infrared pair tube detection switches 29 and an infrared detection pair tube baffle 210. A set of infrared pair tube detection switches 29 are fixedly connected to one side of the lead screw 24, and an infrared detection pair tube baffle 210 is fixedly connected to the moving member 26. The infrared pair tube detection switches 29 and the infrared detection pair tube baffle 210 are arranged on the same vertical plane. The motor 22 is installed and connected with a motor housing 211, and the battery 27 is connected with a battery pressing plate 28.

[0033] Among them, the infrared pair tube detection switches 29 cooperate with the infrared detection pair tube baffle 210 to form limits for the movement at both ends. A set of infrared pair tube detection switches 29 are respectively arranged at the limit positions of the moving stroke at both ends of the moving member 26. The infrared detection pair tube baffle 210 connected to the moving member 26 triggers the infrared pair tube detection switches 29. When the moving member 26 moves to the limit positions at both ends, the infrared rays of the infrared pair tube detection switches 29 are blocked by the infrared detection pair tube baffle 210, thereby controlling the motor 22 to stop rotating, avoiding excessive movement of the lead screw 24 driving the moving member 26, and placing the plastic seat board 11 at the required position. At the same time, the motor housing 211 protects the motor 22, and the battery pressing plate 28 protects the battery 27.

[0034] Please refer to Figures 1-7 Figures 1-7 , the control component 4 includes a bottom case 41 and a PCB main board 45. The bottom case 41 is embedded and installed in the plastic seat board 11. A group of springs 42 are connected inside the bottom case 41. One end of the spring 42 is connected to a key board 43. A gravity sensing module 44 is connected at the middle position of the bottom case 41. The gravity sensing module 44 is electrically connected to the PCB main board 45. The PCB main board 45 is electrically connected to the motor 22. The PCB main board 45 is electrically connected to a power switch 46 and a charging port 47. The PCB main board 45 is electrically connected to a battery 27. The set height of the key board 43 is less than the set height of the top surface of the wooden board 12. The key board 43 is strip-shaped. The control component 4 further includes an infrared sensing module 48. The infrared sensing module 48 is arranged at the bottom of the plastic seat board 11. A lens is arranged on the outer surface of the infrared sensing module 48.

[0035] Among them, the gravity sensing module 44 inside is installed through the bottom case 41. The key board 43 is elastically connected by the spring 42 of the bottom case 41. The key board 43 triggers the gravity sensing module 44, and the corresponding signal is transmitted to the motor 22 through the PCB main board 45 to start and control the motor 22, so as to control the unfolding or folding of the plastic seat board 11. The lower key board 43 avoids accidental touch when a person sits. The infrared sensing module 48 on one side of the plastic seat board 11 conducts infrared sensing. When it senses that a person on one side is standing directly in front for more than the set time, it automatically controls the motor 22 to unfold horizontally. The lens on one side of the infrared sensing module 48 provides protection to achieve intelligent control. The power switch 46 turns on and off the whole device. The charging port 47 on one side charges the device.

[0036] The overall working principle is as follows: The base 15 is connected to the wall, and the support feet 34 are fixed on the floor. A wooden board 12 is embedded in the upper part of the plastic seat board 11, and the wooden board 12 provides contact support for the human body. One side of the plastic seat board 11 is movably connected to the base 15 through a hinge 13 and a hinge connecting piece 14. The movable plastic seat board 11 is convenient for rotation. Inside the plastic seat board 11, a driving gear 25 is driven by a motor 22, which in turn drives a lead screw 24. The lead screw 24 drives a moving part 26 connected by threads through the forward and reverse rotation of the motor 22. The moving part 26 drives a connecting rod 33 to move horizontally in the middle of the plastic seat board 11, and then drives a plastic support plate 32 to move horizontally at the bottom of the plastic seat board 11. The control component 4 conducts overall control. During the horizontal movement of the plastic seat board 11, the support rod 31 is driven to move, so that the plastic seat board 11 can be folded or laid flat. When the plastic seat board 11 is laid flat, the moving part 26 reaches the limit position, and the plastic support plate 32 is limited by the connecting rod 33. At the same time, the plastic support plate 32 abuts against the arc-shaped abutting groove on the bottom side of the plastic seat board 11 to provide stable support for the plastic seat board 11. A stable triangular support is formed by the plastic seat board 11, the support rod 31 and the wall. When folding is required, the motor 22 is reversely rotated by the control component 4, so that the moving part 26 moves horizontally in the reverse direction, driving the plastic support plate 32 to move, and then the plastic seat board 11 is folded vertically upwards. After folding is completed, the lead screw 24 limits the moving part 26. The plastic seat board 11 is folded and unfolded through the power component 2 and the support component 3. When in use, the plastic seat board 11 is placed horizontally to provide a flat sitting position, and when not in use, it can be folded vertically to save space and effectively improve space utilization. Limitation is formed by the infrared pair tube detection switch 29 and the infrared detection pair tube baffle 210 through the movement at both ends. A group of infrared pair tube detection switches 29 are respectively arranged at the limit positions of the moving stroke at both ends of the moving part 26. The infrared detection pair tube baffle 210 connected to the moving part 26 triggers the infrared pair tube detection switch 29. When the moving part 26 moves to the limit positions at both ends, the infrared rays of the infrared pair tube detection switch 29 are blocked by the infrared detection pair tube baffle 210, thereby controlling the motor 22 to stop rotating, avoiding excessive movement of the lead screw 24 driving the moving part 26, and placing the plastic seat board 11 at the required position. At the same time, the motor housing 211 protects the motor 22, and the battery pressing plate 28 protects the battery 27. The bottom shell 41 installs the internal gravity sensing module 44. The bottom shell 41 elastically connects the key board 43 through a spring 42. The key board 43 triggers the gravity sensing module 44, and the corresponding signal is transmitted to the motor 22 through the PCB main board 45 to control the start of the motor 22 and control the unfolding or folding of the plastic seat board 11. The lower key board 43 avoids accidental touch when a person is sitting. The infrared sensing module 48 on one side of the plastic seat board 11 conducts infrared sensing. When it senses that a person is standing directly in front of one side for more than the set time, it automatically controls the motor 22 to expand horizontally. The lens on one side of the infrared sensing module 48 is protected to achieve intelligent control.The power switch 46 turns the device on and off as a whole, and the charging port 47 on one side charges the device.
