Description
Technical field
The invention belongs to perambulator field more particularly to a kind of perambulator control systems and its control mainboard.
Background technique
The perambulator of the prior art, control line arrangement is extremely complex, and is attached using power line, power line
10 times of the usually normal control line of outer diameter or more, to deepen the cumbersome of wiring technique, while considerably increasing perambulator
Production cost and the production efficiency for reducing perambulator.For this purpose, applicant gos deep into prior art perambulator system architecture
Research, the schematic wiring diagram shown in Figure 1 for prior art perambulator, switch panel use mechanical switch and directly with power supply and
Motor is connected, and there are three double-point double-throw switch and a throttle button to show out referring to fig. 2 for setting on general perambulator
The logic control chart that connection is switched in panel is closed, by the logic switch that these are switched, to realize the control of the various modes of perambulator
System.Wherein, three double-point double-throw switch are respectively control of retreating, speed control, mode (manually or remote control) selection, control of retreating
It is to be realized by switching the power supply direction of rear-wheel motor；In the prior art, two rear-wheels of perambulator respectively connect an electricity
Machine, the two motor speeds are different, and do not work at the same time, by switching different motor work to realize second gear speed control
System.When S/CO is fast state, fast state is realized in the fast motor work of revolving speed；When S/CO is
At a slow speed when state, state at a slow speed is realized in the slow motor work of revolving speed.Therefore, in prior art perambulator control system, above-mentioned three
A double-point double-throw switch is the core that entire perambulator manually controls, and all cablings in perambulator require to come around these three switches
It carries out.Due to realizing various controls using direct Switching power, high current can be flowed through this requires control line must use
Power line (as shown in Figure 1, Figure 2, wherein wiring is all high current power line), in this mode, due to using direct Switching power control
Motor processed, perambulator since transient acceleration mutation will cause child's seat shakiness and go out when starting or forward-reverse switch
Existing unsafe condition；Simultaneously because switch is in the front of perambulator, and power supply and rear-wheel motor and connecting plate be at the rear portion of perambulator, then

The cabling back and forth between the connecting plate, motor, power supply at perambulator rear portion, becomes very complicated so as to cause wiring.In practical application,
Conducting wire used by entire perambulator is entirely 10 amperes of high current conducting wire, uses 19 altogether, this is to cause to be produced into
This excessively high principal element.
Meanwhile in terms of being remotely controlled realization, the prior art is using individual infrared or bluetooth module (wireless receiving mould
Block), each perambulator has individual remote controler.Wireless receiving module is located on connecting plate, and connecting plate is the tail in perambulator
Portion, it with the mode selection switch of perambulator front in addition to that will connect, it is also necessary to it is connect with the front-wheel steer motor of front, thus plus
Deep wiring it is cumbersome；In terms of remote controler, each perambulator also needs to individually produce a remote controler, this also affects production
Efficiency and make cost excessively high.
