Embodiment 1, as shown in fig. 1 to 4, the present embodiment aims to solve the technical problems of the existing lifting device for a learning chair, and the control system of the present embodiment controls the lifting structure of the lockable pneumatic rod, and implements the lifting or lowering control of the seat by controlling the electromagnetic valve.
Therefore, the air spring lifting mechanism provided by the embodiment comprises the upright post 3 and the inner tube 2 sleeved in the upright post 3, and the inner tube 2 and the upright post 3 are in telescopic connection, so that the structural design of the conventional common telescopic rod is formed between the inner tube 2 and the upright post 3, in order to realize automatic telescopic operation between the inner tube 2 and the upright post 3, the lockable air spring 6 is sleeved in the inner tube 2, wherein the fixed end of the lockable air spring 6 is fixedly connected with the inner tube 2, the power end of the lockable air spring 6 is fixedly connected with one end, far away from the inner tube 2, of the upright post 3, and a thin tube of the lockable air spring 6 penetrates through the upright post 3 and stretches out of the upright post 3.
In this embodiment, the mechanism motion principle is as follows:
the center of a piston rod (a power end) of the lockable gas spring 6 is provided with a thin rod, the thin rod penetrates through the top of the upright post 3, the top of the upright post 3 is provided with a handle cap 1, the handle cap 1 is sleeved and fixed on the top of the upright post 3, in the embodiment, the handle cap 1 is fixed by a bolt, a through hole is formed in the handle cap 1 and used for the thin rod to penetrate through, a groove is formed in the outer side of the through hole, a switch flexible plate 11 is arranged in the groove, the switch flexible plate 11 comprises a connecting part connected with the thin rod and a control part arranged on one side of the connecting part, a rotating shaft 18 is arranged at the connecting part of the connecting part and the control part, the section of the connecting part is in a toppling U shape, the thin rod is connected with a round hole at the bottom A1 of the connecting part, the control part B1 is connected with a telescopic end of an electromagnetic push rod 14, when the telescopic end of the electromagnetic push rod 14 pushes up the B2, the piston rod of the lockable gas spring 6 is opened by pressure at the other end of the switch flexible plate 11, a controllable valve on the thin rod drives the piston rod to open and close, the piston drives the upright post 3 to rise, and the upright post 3 drives a mechanical seat to rise; conversely, the electromagnetic push rod 14 is retracted and reset, the switch flexible plate A1 is pulled up, the thin rod of the piston rod of the lockable gas spring 6 is closed, and the upright post 3 is at the raised height; when the child sits on the chair, if the piston rod thin rod of the lockable gas spring 6 is opened, under the action of the weight, the controllable valve of the lockable gas spring 6 is opened, and the piston rod is retracted, so that the upright post 3 is driven to move downwards, and the upright post 3 is driven to be mechanically connected with the chair seat to descend. In this embodiment, the end of the thin rod of the piston rod is sleeved with a button 19 and a compression spring 20 for resetting the button 19, taking into account possible instability of the operation of the electromagnetic push rod.
In this embodiment, the control system works as follows:
the relay at the output end of the wireless relay electronic board 12 is conducted, the electromagnetic push rod 14 is electrified to work, and the telescopic rod extends out; the relay at the output end of the wireless relay electronic board 12 is disconnected, and the electromagnetic push rod 14 is retracted without electricity to stop working; similarly, when the child is seated on the chair, a downlink distance sensor 5 is arranged between the upright post 3 and the inner tube 2, the upright post 3 moves downwards, the in-tube touch component enters the downlink distance sensor 5 to set a stroke value, a feedback level signal of the downlink distance sensor 5 is transmitted to a signal input end of the wireless relay electronic board 12, a relay at an output end of the wireless relay electronic board 12 is conducted, the electromagnetic push rod 14 stops working without electricity, a telescopic rod of the electromagnetic push rod 14 is retracted, and a thin rod of a piston rod of the gas spring 6 can be locked to be closed; when the touching part in the upright post 3 pipe enters the ascending distance sensor 4 to set a stroke value, a feedback level signal of the distance sensor is transmitted to the signal input end of the wireless relay electronic board 12, the relay at the output end of the wireless relay electronic board 12 is conducted, the electromagnetic push rod 14 stops working without electricity, the telescopic rod of the electromagnetic push rod 14 is retracted, and the thin rod of the piston rod of the gas spring 6 can be locked to be closed. Of course, a corresponding power supply 15 should be provided on the learning desk to provide power.
In this embodiment, when the control system cannot work, the seat lifting operation principle is implemented as follows:
when the battery is in a power failure state or one element of the control system fails, the button 19 can be manually pressed down, the thin rod of the piston rod for opening the lockable gas spring 6 is opened, and if the seat height is in a low position, the seat is driven by the upright post 3 to rise under the action of the lockable gas spring force; if the seat height is in the high position, the upright 3 can be moved down to the appropriate seat height by hand or leg pressure.
In the implementation method 2, the B2 can be pulled upwards through the handshake of the switch flexible plate 11, so that when the switch flexible plate 11 is opened, the piston rod thin rod of the lockable gas spring 6 is positioned at a low position, and the chair seat is driven to rise under the thrust of the lockable gas spring 6 under the drive of the upright post 3; if the seat height is in the high position, the upright 3 can be moved down to the appropriate seat height by hand or leg pressure.
In this embodiment, the control system safety protection operating principle is as follows:
when no manual operation exists and the lockable gas spring 6 has an abnormal condition, the pressure detection head 17 of the wireless pressure sensor 16 module is attached to one end of the switch flexible board 11 to detect that the pressure is too high or too low, and the output end of the pressure sensor 16 module outputs a high-level signal to trigger the buzzer 13 module to sound; when corresponding APP is installed, the output signal of the wireless pressure sensor 16 module can be connected with the signal input end of the wireless relay electronic board 12 at the same time, and the signal with too high or too low pressure is detected and transmitted to the APP through the gateway, so that the child parent chair is reminded of dangerous too high pressure or the lockable gas spring 6 with too low pressure is damaged, and the child seat is in a sliding condition on the chair.
When the lockable gas spring 6 has too high pressure, besides the sounding work of the buzzer 13 module, the wireless pressure sensor 16 module outputs a signal to the signal end of the wireless relay electronic board 12, the wireless relay electronic board 12 starts a preset program, the electromagnetic push rod 14 is electrified to work, so that the lockable gas spring 6 opens a valve, the thrust rises the upright post 3, and meanwhile, the excessive pressure is discharged.
In this embodiment, the wireless relay electronic board 12 is a four-way wireless relay electronic board 12, a pressure sensor 16 and a distance sensor which are manufactured by Zhongmao technologies and manufactured by Co., ltd and have the model of CT-LCZB5023-FB, and can be matched with each other at will.
