Receive and transmit signal by bluetooth approach between device 11.Certainly, described signal projector 10 and signal receiver 11 can also be logical
The wireless transmission method crossing other carries out signal transmission, such as remote sensing signal transmission etc..
In implementation power-assisted children trolley moves ahead, when described upper push-rod 9 is applied thrust, described upper push-rod 9 is to close
Sliding in the direction of lower push-rod 8, the resistance value of described slide rheostat reduces, and described controller 3 controls the output of described motor 1 and turns round
Power or rotating speed increase；When described upper push-rod 9 is applied pulling force, described upper push-rod 9 slides to the direction away from lower push-rod 8, institute
The resistance stating slide rheostat increases, and described controller 3 controls outputting torsion or the rotating speed reduction of described motor 1.
Described slide rheostat has resistance higher limit and lower resistance limit value.When the resistance of described slide rheostat drops to
During lower resistance limit value, described controller 3 controls motor 1 and keeps the first rotating speed uniform rotation；Resistance when described slide rheostat
When rising to resistance higher limit, described controller 3 controls motor 1 and keeps the second rotating speed uniform rotation, described first rotating speed to be more than
Second rotating speed.
When user implementation power-assisted children trolley is walked on level land, upper push-rod 9 applying thrust, upper push-rod 9 is downward
Sliding, the resistance value of described slide rheostat reduces, and the outputting torsion of described motor 1 increases, and described power-assisted children trolley obtains
The power-assisted of motor 1, user carries out the laborsaving convenience of power-assisted children trolley；Upper push-rod 9 is applied pulling force, upper push-rod 9 upward sliding,
The resistance value of described slide rheostat increases, and the outputting torsion of described motor 1 reduces, the motor that described power-assisted children trolley obtains
1 power-assisted reduces, and described power-assisted children trolley slows down.User is the biggest to the thrust of upper push-rod 9, the outputting torsion of motor 1 or turn
Speed is the biggest, and the power-assisted that described power-assisted children trolley obtains is the biggest, and described user carries out that power-assisted children trolley is the most laborsaving or power-assisted
Children trolley pace is the fastest.User is the biggest to the pulling force of upper push-rod 9, and outputting torsion or the rotating speed of motor 1 are the least, described
The power-assisted that power-assisted children trolley obtains is the least, and the speed that described power-assisted children trolley advances is the slowest.
When power-assisted children trolley goes up a slope walking, user needs bigger thrust to promote power-assisted children trolley up.Make
User applies thrust to upper push-rod 9, and the resistance value of slide rheostat declines, and described motor 1 starts to rotate to power-assisted children trolley
Thering is provided power-assisted, such user can be carried out power-assisted children trolley the most effortlessly and advance.When under the resistance value of slide rheostat
When being down to lower resistance limit value, motor 1 keeps the first rotating speed uniform rotation, and the power-assisted that power-assisted children trolley obtains is not further added by, and helps
Power children trolley can at the uniform velocity advance, it is possible to effectively prevents power-assisted excessive, and assist motor rotating speed is too fast, pushes away passerby and cannot follow and help
The situation of the speed of power children trolley occurs, and also can effectively protect assist motor, prevent assist motor overload operation.
When power-assisted children trolley descending is walked, in order to prevent descending too fast the rushing out of power-assisted children trolley from safe thing occurring
Therefore, user needs bigger pulling force to hold the speed that power-assisted children trolley control power-assisted children trolley is descending.User is to upper
Push rod 9 applies pulling force, and the resistance value of slide rheostat rises, and the power-assisted that described motor 1 provides reduces.Pulling force is the biggest, and motor 1 carries
The power-assisted of confession is the least, and when the resistance value of slide rheostat rises to resistance higher limit, motor 1 keeps the second rotating speed at the uniform velocity to turn
Dynamic, power-assisted children trolley remains a constant speed advance, it is possible to effectively prevent power-assisted children trolley downstream rate too fast, and user cannot be with
Occur that with the speed of power-assisted children trolley the situation of security incident occurs.I.e. user can control power-assisted child the most effortlessly
The speed that go-cart is descending.
As it has been described above, we are illustrated fully according to objective of the present utility model, but this utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit at technological thought of the present utility model
Inside carry out different changes and enforcement.
