Embodiment two:
The present embodiment and embodiment one are based on identical inventive concept, specifically disclose the power-assisted purchase in a kind of embodiment one
The weight bearing of object vehicle is climbed method, which includes the following steps.
Step 1, it is pushed away by way of pressing remote controler to electronic in upper bus with hand steered the handle 2 of shopping cart
The controller of bar issues control signal, and the present invention enables 1 He of shopping basket by way of controlling electric pushrod expansion link and stretching out upwards
Front vehicle wheel 8 is synchronous to be risen, so that vehicle bottom be made to separate with shopping basket, and then the wheel bottom height of front vehicle wheel 8 is made to be greater than bus
Pedestrian's step height (or getting-on platform for bus), to guarantee that shopping basket height rises to and bus podium level
Unanimously.
Step 2, shopping cart is pushed forward, and the elderly makes front vehicle wheel it is only necessary to touch the handle 2 of shopping cart at this time
Above 8 pedestrian's pedals in bus, even the front vehicle wheel connecting with shopping basket is introduced into shopping cart, it is slow to reach shopping basket 1
The slow purpose into bus.
Step 3, it when shopping basket 1 is stablized and fallen on pedestrian's pedal of bus, is received by control electric pushrod expansion link
The mode returned enables front vehicle wheel 8 fall on pedestrian's pedal of bus, for example, by pressing the control button side on shopping cart handle
Formula is realized.
Step 4, rear wheel 9 rises during electric pushrod expansion link is withdrawn, and support device 11 can fall automatically, with
It enables support device 11 fall on pedestrian's pedal of bus, at this point, front vehicle wheel 8 and support device 11 support shopping basket 1 jointly, makes
Shopping basket 1 has preferable stability.Since shopping basket 1 and front vehicle wheel 8 have been fixed at this time, electric pushrod expansion link withdraws dynamic
Make reversely electric pushrod itself and rear wheel to be driven to move upwards, until electric pushrod returns to original state.
Step 5, after the completion of electric pushrod expansion link is withdrawn, continuation pushes forward shopping cart, to enable rear wheel 9 fall in public affairs
On the pedestrian's pedal for handing over vehicle, process of climbing is completed.
The present invention can make the power-assisted shopping cart for being mounted with weight easily climb up bus, have laborsaving time saving, operation
The advantages that facilitating, to thoroughly solve the worry of the upper bus difficulty of the users such as the old man of carrying shopping cart.
In addition, driving its rear wheel to land by electric pushrod under the shopping cart for making to take weight when bus, to pusher
Dynamic shopping cart and the mode for making front vehicle wheel land are completed, realize process almost with upper bus process on the contrary, the present embodiment not
It repeats again.
Embodiment three:
The present embodiment and embodiment one are based on identical inventive concept, specifically disclose the power-assisted purchase in a kind of embodiment one
The weight bearing of object vehicle is climbed method, which includes the following steps.
Step a tilts backwards the top of guide part 3 using the axis of rear wheel as shaft, to enable the invention to climb
More Gao Taijie.
Step b enables front vehicle wheel 8 and shopping basket 1 slowly rise by way of controlling electric pushrod expansion link and stretching out upwards,
So that the wheel bottom height of front vehicle wheel 8 is greater than step height.
Step c, pushing forward while shopping cart makes the top of guide part 3 turn forward, and enables front vehicle wheel 8 and support device
11 all fall on the top surface of step, and rear wheel 9 is enabled to stick on the side of step.
Step d, control electric pushrod expansion link are withdrawn, and rise to step to enable rear wheel 9 roll along the side of step
Top surface on.Since shopping basket 1 and front vehicle wheel 8 have been fixed at this time, electric pushrod expansion link withdrawal movement can reversely drive electricity
Dynamic push rod itself and rear wheel move upwards, until electric pushrod returns to original state.
Step e completes process of climbing after the completion of electric pushrod expansion link is withdrawn.
It should be appreciated that the embodiment of the present invention two, embodiment three can be combined with each other, for example first make to be oriented in upper bus
The top of part tilts backwards, and for another example, front vehicle wheel and shopping basket is directly risen to proper height etc. when across step.
