Detailed Description
As shown in fig. 1, the two-wheeled power-assisted hand truck of the present invention includes:
a battery for providing electrical power;
the hub motor is used for providing power;
the electromagnetic brake is used for controlling the operation of the hub motor and is connected with the hub motor;
the wheel is connected with the hub motor;
the speed regulation brake handle is used for controlling the forward movement, the backward movement and the braking of the vehicle and regulating the speed of the vehicle;
and the controller is connected with the electromagnetic brake, the hub motor, the battery and the speed regulation brake handle respectively, and is used for receiving a signal of the speed regulation brake handle and controlling the operation of the hub motor according to the signal.
The invention relates to a two-wheel power-assisted trolley, wherein a reduction gearbox is arranged in a shell of an in-wheel motor, and the in-wheel motor is connected with wheels through the reduction gearbox.
The invention provides a two-wheeled power-assisted trolley, wherein a quick-release tire is mounted on each wheel.
The invention relates to a two-wheeled power-assisted trolley, wherein an electromagnetic brake is integrated in a shell of a hub motor, and the electromagnetic brake is connected with a speed regulation control handle by adopting a pull wire.
The two-wheeled power-assisted trolley has a simpler transmission structure, reduces the failure rate of a driving system, can obtain better space utilization rate, improves the transmission efficiency, and further increases the maneuvering performance of vehicles.
The hub motor driving system with fast detaching and neutral gear running includes speed regulating brake handle, controller, large capacity battery, hub motor, electromagnetic brake, fast detaching tyre and other parts.
The speed regulation brake handle is connected with the controller, transmits signals to the controller, carries out high-low gear and reverse gear operation according to corresponding commands through the controller, and is connected with the controller through a cable;
the high-capacity battery is an energy source of the whole two-wheel power-assisted trolley driving system which is driven by the wheel hub motor, is connected with the controller through a cable and supplies power to the controller, and meanwhile, supplies power to the motor after being processed by the controller.
The controller is a core control unit and is used for receiving and processing signals from the speed-regulating brake handle so as to drive the motor to work and drive the tire to move forwards, and the controller is connected with the hub motor through a cable and is connected to the tire position from the battery box part;
the hub motor is a power source of the whole driving system, the reduction gearbox is integrated in the hub motor, the power provided by the motor is firstly transmitted to the reduction gearbox, the torque is amplified by the reduction gearbox and converted into a rotating speed value matched with the driving speed requirement of the cart, so that the cart can meet the driving speed requirement;
the electromagnetic brake is integrated at the hub motor part and is connected with the speed regulation control handle by adopting a stay wire type. When the electromagnetic brake works, the speed regulation brake handle acts and gives a corresponding signal to the electromagnetic brake to enable the electromagnetic brake to work.
When the power is off, the clutch of the hub motor is disconnected, the motor and the speed reducer do not provide resistance, the empty vehicle runs in a neutral gear, and when the power is on, the clutch is closed, and the power of the motor can be transmitted to the tire through the speed reducer.
The quick-dismantling hub motor is connected with the axle through the fixed locking device, and when the wheel hub motor needs to be dismantled and stored, the wheel hub motor can be directly dismantled and stored.
By adopting the structure and the technical scheme, the power-assisted trolley can be conveniently disassembled and assembled and can run without resistance when power is off. When the power-assisted hand cart is stored, the two tires can be quickly disassembled, the whole cart frame is used as one part, the two hub motors are used as two parts, and the three parts are stored and placed.
The speed regulation brake handle is connected with the controller through a cable and a connector, the battery is connected with the controller through a cable and a connector, the controller is connected with the hub motor through a cable and a connector, the stator of the hub motor is fixed through a stator bracket, the rotor of the hub motor is connected with a brake disc, the electromagnetic brake is connected with the rotor bracket, the rotor bracket is connected with a wheel supporting part, the wheel supporting part is connected with an external tire, and the hub motor is connected with the axle through a fixed locking device.
When the cart advances, the controller receives a signal of a speed-regulating brake handle, drives the motor to rotate forwards, and transmits power to the quick-release tire through the hub motor reducer to enable the axle to advance;
when the cart retreats, the controller receives a signal of a speed-regulating brake handle, drives the motor to rotate reversely, and transmits power to the quick-release tire through the hub motor reducer to enable the axle to retreat;
when the cart brakes, the controller receives a signal of the speed-regulating brake handle and controls the electromagnetic clutch brake to brake. When the brake is stopped, the controller releases the electromagnetic clutch brake to stop the brake of the axle, so that the cart can normally run;
when the electric quantity of the storage battery is insufficient, the controller stops supplying power to the electromagnetic clutch after detecting that the electric quantity is insufficient, the electromagnetic clutch is disconnected, and therefore resistance is not brought by linkage of other mechanisms when the non-driven tire rotates.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
