Embodiment only the preferred embodiments of the present invention are stated, and it is not all.Based on the embodiment in embodiment, those skilled in the art
Other embodiment is obtained on the premise of creative work is not made, protection scope of the present invention is belonged to.
In the following description, occur the indicating position such as term " interior ", " outer ", " on ", " under ", "left", "right" or
Position relationship is that, based on orientation shown in the drawings or position relationship, description embodiment merely for convenience is described with simplified, and
It is not instruction or implies that signified device or element there must be specific orientation, with specific azimuth configuration and operation, because
This is not considered as limiting the invention.
Embodiment 1：
As shown in Figures 1 to 4, the present embodiment for it is a kind of control drive device hand controller, be mainly used in control maintenance bed,
Medical bed etc., naturally it is also possible to be used in field of furniture, hand controller includes shell 1 and the control board 2 being located in shell 1,
Multiple buttons 21 are also provided with control board 2, shell 1 is provided with the perforation 101 passed through for these buttons 21, button press
21 can accordingly control each key switch in shown control board 2.
In the present embodiment for traditional hand controller, key is on shell 1 to set slot 102, and sets
The magnetic stripe that magnet in magnet, the present embodiment is strip is provided with the key 3 of one pluggable slot 102, key 3, outside
The inside of shell 1 sets magnetic induction switch 22 in magnetic induction switch 22, the present embodiment to be preferably mounted in control board 2, magnetic induction
Switch 22 is that power on/off is realized using the effect in magnetic field, and the structure of itself of magnetic induction switch 22 has been more conventional skill
Art, does not make magnetic induction switch 22 in excessive elaboration, the present embodiment and is preferably tongue tube, the structure of tongue tube mainly relies on two
Shell fragment attracts each other to realize path under magnetic fields, and the structure of tongue tube has also been to know technology in field of switches, no
Make excessive illustrate.Certain magnetic induction switch 22 can also be Hall switch etc., as long as control circuit to lead to using magnetic fields
It is disconnected it is equal can be with.
In the present embodiment, exactly using this characteristic of tongue tube, using the key 3 of the plug type of a magnet carrier,
To carry out control system of switching on or off electricity to magnetic induction switch 22, when key 3 inserts 102 inside of slot, the magnet in key 3 is close to dry spring
Pipe, thus allow tongue tube connect control board 2 circuit, user just can with opponent control device be operated；And when key 3 from insert
When the inside of groove 102 is extracted, the magnet in key 3 is away from tongue tube, and tongue tube accordingly disconnects, so that control board 2
Circuit also disconnects, and user cannot operate to hand controller.
It should be noted that key 3 signified in the present invention inserts or pull out the slot 102, it is not limited to completely
Insertion is extracted completely, is only inserted a part or is only extracted a part, as long as magnet is closer or far from magnetic induction switch 22,
As for distance of the magnet closer or far from magnetic induction switch 22, this is the bullet in magnetism intensity or magnetic induction switch 22 with magnet
The bending strength of piece is relevant, that is, so-called distance of reaction, and magnetic induction switch 22 on the market has many distance of reaction, it is impossible to
Exhaustion, in the present embodiment, the distance of reaction of magnet and tongue tube can be between 0.5mm~10mm, it is contemplated that assembly difficulty, magnetic
Feel intensity combination property, preferably 4mm, 5mm be can be with.
In order to allow key 3 to insert after slot 102, the channel status of stable holding control board 2, the hand controller is also wrapped
