Description
Technical field
The present invention relates to one kind control circuit, specifically a kind of petal of baby carriage switch safety control circuit.
Background technology
Existing perambulator, in the moment that floor push disconnects, floor push is anti-electronic due to motor by motor short circuit
Gesture, disconnection moment still has electric current to flow through floor push, and current strength is about 40A, because the rated current of floor push is
30A, therefore in the moment for lifting floor push, its rated current is exceeded by the electric current of floor push, occasionally there is floor push quilt
The situation of fusing occurs.
The content of the invention
It is an object of the invention to provide a kind of petal of baby carriage switch safety control circuit, with solving above-mentioned background technology
The problem of proposition.
To achieve the above object, the present invention provides following technical scheme：
A kind of petal of baby carriage switch safety controls circuit, and the break-make of circuit, 5 pin relays are realized by a 5 pin relays
A normally closed switch and a normal open switch, normal open switch connection circuit anode and negative pole, normally closed switch connection electricity are included in device
The both positive and negative polarity of machine, when closing of circuit is controlled, normally closed switch is opened, normal open switch closure, and circuit is connected, when control circuit breaks
When opening, normal open switch is opened, and circuit disconnects, normally closed switch closure, and motor circuit is connected；By a 4 pin relays by electricity
Connected between machine both positive and negative polarity, 4 pin relays include a normally closed switch, short between motor both positive and negative polarity when controlling switch disconnects
Connect.The electric current of operating circuit is controlled by controller.
As further scheme of the invention：The 5 pin relay and 4 pin relays are by floor push control.
Compared with prior art, the beneficial effects of the invention are as follows：Excessive cause present invention, avoiding the electric current by switching
Fusing, high current is controlled with low current by relay, switch is placed in different circuits from operating circuit, therefore pass through
The electric current of switch is smaller, it is to avoid the fusing for being exceeded its rated current and being caused by the electric current for switching in operating circuit；Letter
Perambulator circuit is changed.Because this improved circuit need not use controller, therefore unnecessary line is eliminated, circuit is connected
Line becomes simple, no longer cumbersome.In industrial production, also for perambulator inside saves space；Avoid what frequent starting caused
Fuse frequently fuses.Transient current control when controller is by circuit start is relatively low, it is to avoid frequently step on pin in the short time
The fuse for causing is stepped on frequently to fuse.
Brief description of the drawings
Fig. 1 is the circuit theory diagrams that petal of baby carriage switch safety controls circuit.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.
Fig. 1 is referred to, in the embodiment of the present invention, a kind of petal of baby carriage switch safety controls circuit, by a 5 pin relays
Device is realized including a normally closed switch and a normal open switch in the break-make of circuit, 5 pin relays, and normal open switch connection circuit is just
Pole and negative pole, normally closed switch connect the both positive and negative polarity of motor, and when closing of circuit is controlled, normally closed switch is opened, normal open switch closure,
Circuit is connected, when controlling circuit to disconnect, normal open switch is opened, and circuit disconnects, normally closed switch closure connects motor circuit
It is logical；To be connected between motor both positive and negative polarity by a 4 pin relays, 4 pin relays include a normally closed switch, work as controlling switch
During disconnection, short circuit between motor both positive and negative polarity.The 5 pin relay and 4 pin relays are by floor push control.By controller
Control the electric current of operating circuit.
Operation principle of the invention is：Refer to Fig. 1,24V power supplys are powered for whole control circuit, by 5 pin after
Electrical equipment is realized including a normally closed switch and a normal open switch in the break-make of circuit, 5 pin relays, normal open switch connection circuit
Positive pole and negative pole, normally closed switch connect the both positive and negative polarity of motor, and when closing of circuit is controlled, normally closed switch is opened, and normal open switch is closed
Close, circuit is connected, when controlling circuit to disconnect, normal open switch is opened, and circuit disconnects, normally closed switch closure, by motor circuit
Connect；To be connected between motor both positive and negative polarity by a 4 pin relays, 4 pin relays include a normally closed switch, when control is opened
When shut-off is opened, short circuit between motor both positive and negative polarity, the 5 pin relay and 4 pin relays are by floor push control.Circuit also leads to
Cross the electric current that controller controls operating circuit.
Present invention, avoiding the excessive fusing for causing of electric current by switching, electricity high is controlled with low current by relay
Stream, switch is placed in different circuits from operating circuit, therefore smaller by the electric current of switch, it is to avoid in operating circuit
The fusing for exceeding its rated current and causing by the electric current for switching；Simplify perambulator circuit.Because this improved circuit is not required to
Controller is used, therefore eliminates unnecessary line, circuit connection is become simple, it is no longer cumbersome.In industrial production,
Also it is to save space inside perambulator；The fuse that frequent starting causes is avoided frequently to fuse.When controller is by circuit start
Transient current control relatively low, it is to avoid the foot-operated fuse for causing frequently is stepped in the short time and is frequently fused.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
