Detailed description of the invention
Being known by Fig. 1, Fig. 2, a kind of single support is played except device, including base 1, is installed with list in the middle of described base 1
Supporting 2, fork 3 is movably connected on base 1 and is positioned at single support 2 fronts, and the front of fork 3 is provided with inductance approach switch II
4, and at base 1, single rear supporting 2 is installed and is also equipped with inductance approach switch I 5；Fork 3 turns clockwise certain angle
Rear conflict inductance approach switch II 4, conflict inductance approach switch I 5 after singly support 2 rotates to an angle counterclockwise.Described
Fork 3 one end connect have motor 6, motor 6 to be DC speed-reducing, and be externally provided with capsul at motor 6, can by capsul
So that motor 6 to carry out waterproofing protection very well, inductance approach switch I 5, inductance approach switch II 4, motor 6 are all electric with control
Road plate 7 connects, and controls each several part by control circuit plate 7 and is operated, and control circuit plate 7 may be installed below vehicle body medicated cushion.
The control circuit plate 7 being arranged on vehicle body carries out rate signal detection, utilizes inductance approach switch II 4 and inductance type close to opening
Close I 5 detection forks 3 and the position of list support 2, utilize DC speed-reducing 6 to rotate to control fork 3, finally realize single support 2
Automatically lift.
Being known by Fig. 3, be circuit controling drawing of the present utility model, described control circuit is by being connected on DC supply input line
On be connected in parallel inductance approach switch I control circuit, inductance approach switch II control circuit, the second relay K2Control
Circuit, motor M are constituted with voltage comparator, and the 3rd foot of voltage comparator connects rate signal line；Described inductance type
Proximity switch I control circuit is by inductance approach switch I, audion Q1, diode D1First relay K1Form with resistance, electricity
First foot of pressure comparator is by resistance R1With audion Q1Connect；Second relay K2Control circuit is by the second relay K2, three
Pole pipe Q2With diode D2Composition, audion Q2By resistance R10It is connected with the 7th foot of voltage comparator；Inductance approach switch
II control circuit is by inductance approach switch II, diode D4With the 3rd relay K3Composition, voltage comparator the 5th foot is by electricity
Resistance R12It is connected with motor M；The first described relay K1By normally closed interlock K1-1、K1-2And normally open contact K1-1、K1-2Two groups of contacts
Composition；The second described relay K2By normally closed interlock K2-1And normally open contact K2-1Composition；The 3rd described relay K3By normally closed
Contact K3-1And normally open contact K3-1Composition；The first described relay K1Normally closed interlock K1-1And between DC supply input line
It is provided with the 3rd relay K3Normally open contact K3-1。
The operation principle of control circuit: connect 12V DC source, in the case of not having rate signal, voltage comparator
First foot output low level, audion Q1Block, the first relay K1Normally closed interlock K1-1、K1-2Power to direct current generator M, by
In normally open contact K3-1Existence, motor M will not obtain electric rotation, and whole device is standby.
If electric motor car starts to walk, rate signal voltage makes voltage comparator the first foot export high level, audion Q1Conducting,
If single heel brace 2 does not lift, inductance approach switch I 5 is normally closed, the first relay K1Obtain electric adhesive, normally open contact K1-1、K1-2
