Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.
In an embodiment of the present invention, a power-assisted cart is provided, referring to fig. 1 to 4, the power-assisted cart includes a frame 1 and at least three wheels 2 disposed at a lower portion of the frame 1, the illustrated cart has four wheels 2 including two front wheels and two rear wheels, and the power-assisted cart further includes an electric power-assisted assembly, the electric power-assisted assembly includes a controller, a power-assisted wheel 31, a power-assisted driving mechanism for driving the power-assisted wheel 31 to rotate, and a lifting mechanism for driving the power-assisted wheel 31 to move up and down; the power-assisted driving mechanism and the lifting mechanism are both connected with the output end of the controller, and the controller is used for sending driving instructions to the power-assisted driving mechanism and the lifting mechanism; under the drive of the lifting mechanism, the power-assisted wheel 31 is switched between a folding position and a using position, when the power-assisted wheel 31 is in the using position, the bottom of the power-assisted wheel 31 is in the same plane with the bottom of the wheel 2, and when the power-assisted wheel 31 is in the folding position, the bottom of the power-assisted wheel 31 is higher than the plane of the bottom of the wheel 2, and at the moment, the power-assisted wheel 31 is suspended when the cart is pushed; the assist wheel 31 is capable of rotating in a direction in which the cart advances or in a direction in which the cart retreats, driven by the assist drive mechanism. Clearly, the electric power assisting assembly further comprises a power supply, the power supply is used for supplying power to the controller and supplying power to the power assisting driving mechanism and the lifting mechanism through the controller, and the power supply is preferably a rechargeable storage battery assembly. Because the power assisting wheel 31 does not participate in the ordinary manpower propelling mode, the power assisting wheel 31 can be detached from the cart for maintenance under the condition that the power assisting wheel 31 needs to be maintained, namely, the normal manpower propelling use of the cart is not influenced.
Specifically, under the drive command of controller, elevating system drives helping hand wheel 31 descends to ground, is promptly with other four wheels 2 with be in a plane (should look at specific shallow frame, wheel height and the installation position relation etc. of electronic helping hand subassembly and frame confirm the decline stroke of helping hand wheel 31), helping hand actuating system can be in when helping hand wheel 31 contacts ground, or in advance a period of time (can with elevating system simultaneous action even before the elevating system moves earlier), or lags behind a period of time and opens, the utility model discloses do not limit helping hand actuating system's opening moment. On the contrary, under the instruction of stopping driving of the controller, the power-assisted driving mechanism stops acting, the lifting mechanism drives the power-assisted wheel 31 to ascend (preferably to reset to the initial height position), and similarly, the lifting mechanism can start the lifting action while the power-assisted driving mechanism stops acting, or in advance for a period of time, or in delay for a period of time, the utility model discloses it is not limited to the moment of opening of the lifting mechanism.

Of course, in the mechanical field, the structure for driving the linear lifting is not limited to the form of the above-mentioned chain wheel, and other modes such as a screw rod can be adopted, and a liftable wheel structure on an airplane can be referred to, which is not described herein again.
Regarding the trigger mode that the controller sent this action of drive command, the embodiment of the utility model provides a two kinds of trigger modes:
the first type is automatic triggering, and specifically, the power-assisted cart further comprises a sensing device electrically connected with an input end of the controller, wherein the sensing device comprises, but is not limited to, an angle sensor for detecting an inclination angle of the cart frame 1, a pressure sensor for detecting pressure applied to a pushing handle of the cart, an image sensor for detecting road conditions, and a speed sensor (one or more of the sensors can be selected) for detecting the rotating speed of the wheels 2; and the controller generates the driving instruction according to the detection signal of the sensing device, namely sends the driving instruction to the power-assisted driving mechanism and the lifting mechanism. Such as: the controller analyzes the angle signal detected by the angle sensor, and if the angle signal is judged to be the upward inclination angle (the uphill state) of the front part of the cart, the controller starts the power assistance to enable the power assistance driving mechanism to drive the power assistance wheel 31 to rotate forwards; if the front part of the cart is judged to be inclined downwards (in a downhill state), the controller starts the boosting to enable the boosting driving mechanism to drive the boosting wheels 31 to rotate backwards (to realize downhill deceleration). For another example: the controller analyzes the pressure signal detected by the pressure sensor, and if the pressure signal is judged to be that the thrust is greater than the pull force and the thrust exceeds a preset thrust threshold, the controller starts the power assistance to enable the power assistance driving mechanism to drive the power assistance wheel 31 to rotate forwards; if the pressure signal is judged to be that the pushing force is smaller than the pulling force and the pulling force exceeds a preset pulling force threshold value, the controller starts the assisting force to enable the assisting force driving mechanism to drive the assisting wheel 31 to rotate backwards. For another example: the controller analyzes the image signals detected by the image sensor, and if the cart is judged to be in a state requiring assistance (such as relatively bumpy road, such as an uphill road or a downhill road), the controller starts assistance to enable the assistance driving mechanism to drive the assistance wheels 31 to rotate forwards or backwards correspondingly. For another example: the controller analyzes the speed signal detected by the speed sensor, and if the current speed is judged to exceed a preset safe speed limit value, the controller starts the power assistance to enable the power assistance driving mechanism to drive the power assistance wheels 31 to rotate in the direction opposite to the advancing direction of the current cart; if the cart is judged to perform deceleration movement at a smaller acceleration (smaller than a preset acceleration threshold) and the deceleration time exceeds a preset time threshold, it is indicated that the cart does not artificially stop moving due to deceleration, and the controller starts the power assistance to drive the power-assisted wheels 31 to rotate in the current cart traveling direction by the power-assisted driving mechanism.
