Problems solved by technology

[0002] At present, many children's learning chairs use pneumatic rods and gas springs to achieve lifting functions, but they still use mechanical force to adjust the height of the pneumatic rods and gas springs; although this structure can realize the height adjustment of the pneumatic rods and gas springs, But there are still the following problems: 1. The lifting of the air pressure rod structure is used to adjust the height correction chair for children of younger ages, and parents need to help to adjust it. When parents are not around, children of younger ages can't realize it if they want to operate; Because the chair uses air pressure rods and air springs due to quality reasons, explosions have occurred. For the safety of children, it is also necessary to design pre-detection or overpressure protection devices.

Embodiment 1

[0020] Example 1, such as Figure 1 ~ Figure 4 As shown, this embodiment aims to solve the technical problems existing in the existing learning chair lifting device. The control object of the control system in this embodiment is the lifting structure of the lockable air rod, and the seat height can be controlled by controlling the solenoid valve. example.

[0021] For this reason, the gas spring lifting mechanism provided in this embodiment includes a column 3 and an inner tube 2 sleeved in the column 3, and the telescopic connection between the inner tube 2 and the column 3, so that the inner tube 2 and the column 3 The structure design of the existing common telescopic rod is formed. In order to realize the automatic expansion and contraction between the inner tube 2 and the column 3, a lockable gas spring 6 is set inside the inner tube 2, wherein the fixed end of the lockable gas spring 6 is connected to the The inner tubes 2 are fixedly connected, the power end of the loc...

Embodiment approach 1

[0027] Implementation method 1: When the battery is short of power or a certain component of the control system fails, you can manually press the button 19 to open the thin rod of the piston rod that opens the lockable gas spring 6. Under the force of the locking gas spring, the seat rises under the drive of the column 3; if the seat height is at a high level, the column 3 can be pressed down and moved to a suitable seat height by hand or leg pressure.

[0028] Implementation method 2: B2 can be pulled up through the handshake of the switch flexible plate 11, so that when the switch flexible plate 11 opens the piston rod thin rod of the lockable gas spring 6, if the seat height is at a low position, under the thrust of the lockable gas spring 6 The chair seat rises under the drive of the column 3; if the seat height is at a high position, the column 3 can be pressed down by hand or leg pressure to move to a suitable seat height.

[0029] In this embodiment, the working princip...

Abstract

The invention belongs to the field of intelligent child learning chairs, and particularly relates to an Internet of Things lifting posture correcting chair control system. The system comprises a standcolumn and an inner pipe sleeved with the stand column. The inner pipe and the stand column are connected in a telescopic mode. A lockable gas spring is sleeved in the inner pipe; wherein a fixed endof the lockable gas spring is fixedly connected with the inner pipe; the power end of the lockable air spring is fixedly connected with the end, away from the inner pipe, of the stand column. A thinrod of the lockable gas spring penetrates through the stand column; a handle cap is arranged at the end, away from the inner pipe, of the stand column, the thin rod penetrates through the handle cap,a switch flexible plate used for controlling the thin rod is arranged on the handle cap, the switch flexible plate and the handle cap are arranged in a coupling mode, remote and short-range detectionand control over the safety performance of the air spring are achieved, and the safety of teenagers using products is protected all the time.
