The normally opened contact series connection access right side lifting motor electrical schematic diagram of SQ2 ~ SQ3, travel switch SQ6 and travel switch SQ8
In secondary circuit, therefore when bed board in upper bed board, lower bed board, transverse direction and lower bed board junction, left plate and vertical middle bed board are appointed
It anticipates after rising at one, right side lifting motor cannot achieve control, avoids and damages to bed board.
Specific work process and working principle are as follows:
When the bed board of this nursing bed is when in a horizontal state, setting is in triggering state in all travel switches, at once
The closed state that journey opens Central Shanxi Plain contact changes, at this time by Fig. 3 ~ Fig. 7 it is found that the normally opened contact of travel switch SQ1 ~ SQ8
It is closed, therefore the motor in Fig. 3 ~ Fig. 7 can act.
When patient needs to alter one's posture, by pressing corresponding key on remote controler, it is remotely controlled relay later by key pressing
The actuating of relay on device plate, connects the coil of corresponding contactor after the actuating of relay, contactor coil is corresponding after connecting
Motor rotate and corresponding bed board driven to act, the normally opened contact of corresponding travel switch disconnects after bed board movement,
The secondary circuit of the motor of the trip of having connected switch disconnects, and corresponding motor can not act, i.e., this nursing bed is laterally arranged
After bed board movement, the driving motor of vertically arranged bed board can not work, horizontal similarly after the vertically arranged bed board movement of this nursing bed
It can not equally work to the driving motor of setting bed board and the vertically arranged bed board in the other side, therefore avoid the bed in some direction
Bed board normal thereto is because accidentally touching the damage made to bed body frame 23 after plate movement, while ensure that the personal safety of patient.
Embodiment 2:
As shown in figure 8, the present embodiment the difference from embodiment 1 is that: in the present embodiment omit banked relay module,
And realized by commercially available common microprocessor, microprocessor is provided with infrared remote receiver, for receiving the infrared of remote controler sending
Signal.Microprocessor realizes the actuating of relay by conventional driving circuit, while micro- place is accessed in the contact of all travel switches
The signal input part for managing device realizes the interlocking between each lifting motor by the programming to microprocessor.
The long-range control of this nursing bed can also be further realized by conventional technical means: such as setting and microprocessor phase
Communication module even, microprocessor access network pass through the company of communication module (such as wifi module) realization and external server later
It connects, and the jacking condition of every piece of bed board is uploaded in server by microprocessor, operator passes through mobile phone (or personal electricity
Brain) software log in the server and can check the working condition of this nursing bed, and can be long-range to nursing bed by server
Control signal is issued, realizes the long-range control to this nursing bed.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
Matter any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the guarantor of technical solutions of the utility model
Protect range.
