Description
Technical field
The present invention relates to a kind of old man power-assisted load-bearing towing dollies, specifically use tension sensor, can be according to load
Lotus determines whether a kind of old man's towing dolly of application power-assisted, belongs to household appliance field.
Background technique
The first half leaf in 21st century is Aged in China population scale unprecedented soaring period.It is 2015,60 years old Chinese or more
About 2.2 hundred million people of elderly population scale, world community first place is occupied, when by 2026, it is contemplated that Aged in China population scale reaches
To about 3.1 hundred million people.
Due to the family planning policy that China carries out, most of families have multidigit the elderly to need to support.The transformation of idea
Cause most of the elderly to live apart with sons and daughters, and young people has the work of oneself, be difficult thorough treatment the elderly,
Many things need the elderly to do it yourself, this just inevitably encounters the demand for carrying the weights such as rice and drinking water.Mesh
Preceding Hand pulling vehicle is for when carrying the lighter things such as dish, use to be more convenient, but when carrying heavy goods, always
Year, people was other than Hand pulling vehicle to be overcome and the resistance on ground, still suffered from the part gravity of weight, so that the elderly can't bear the heavy load,
Hence it is imperative that a kind of new power-assisted load-bearing Hand pulling vehicle, can slow down weight and trolley be applied to pulling force with the elderly and
Pressure mitigates the burden of the elderly.
Summary of the invention
In view of the above-mentioned deficiencies, the present invention provides a kind of old man power-assisted load-bearing towing dollies.
The present invention is achieved by the following technical solutions: a kind of old man's power-assisted load-bearing towing dolly, including towing dolly, drawing
Force snesor, telescopic rod, support rod, support frame, battery, electric drive integrated wheel, controller, buckle, the telescopic rod upper end hinge
It connects on the cross bar on towing dolly, support rod both ends are respectively hinged on the cross bar and telescopic rod of towing dolly.Tension sensor peace
On towing dolly vertical bar, support frame is fixed on centre on telescopic rod and is fixed on support frame by lower portion, battery, electric drive one
Body wheel is fixed on the lower end of telescopic rod.Controller is fixed on support frame, and 2 buckles are fixed among towing dolly on vertical bar, is in
It is arranged above and below.
The telescopic rod includes telescopic rod upper boom, telescopic rod connection sleeve, telescopic rod lower beam, telescopic rod upper boom lower bands
There is left hand thread, telescopic rod lower beam top has right-handed thread, and telescopic rod connects sleeve side and has to be cooperated with telescopic rod upper boom
Left hand thread, the other end has the right-handed thread that cooperates with telescopic rod lower beam.
The support rod includes support rod upper boom, support rod connecting sleeve cylinder, support rod lower beam, support rod upper boom lower bands
There is left hand thread, support rod lower beam top has right-handed thread, and support rod connecting sleeve cylinder side has to be cooperated with support rod upper boom
Left hand thread, the other end has the right-handed thread that cooperates with support rod lower beam.
The usefulness of the invention is the pulling force born when alleviating the elderly's carrying heavy goods and pressure, especially when upper
When slope or heavier carrying heavy goods, by applying power-assisted, the burden that the elderly drags Hand pulling vehicle can be mitigated, improve the life of old man
Bioplasm amount；By adjusting the length of support rod, it is applicable to the elderly of different heights；It is arranged by controller to pull sensing
Threshold value, the speed of service of towing dolly of device reaction, to adapt to different old man's constitutions；It, can be by support rod when not needing carrying heavy goods
Disassembly, load-bearing towing dolly become common towing dolly, realize the simple conversion of common towing dolly Yu load-bearing towing dolly.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the present invention.
In attached drawing, 1, towing dolly, 2, tension sensor, 3, telescopic rod, 301, telescopic rod upper boom, 302, telescopic rod connector sleeve

Specific embodiment
A kind of old man's power-assisted load-bearing towing dolly, including towing dolly 1, tension sensor 2, telescopic rod 3, support rod 8, support
Frame 6, battery 4, electric drive integrated wheel 7, controller 5, buckle 9,3 upper end of telescopic rod is hinged on the cross bar on towing dolly 1, support
8 both ends of bar are respectively hinged on the cross bar and telescopic rod 3 of towing dolly 1.Tension sensor 2 is mounted on 1 vertical bar of towing dolly, support
Frame 6 leans on lower portion among being fixed on telescopic rod 3, and battery 4 is fixed on support frame 6, and electric drive integrated wheel 7 is fixed on telescopic rod
3 lower end.Controller 5 is fixed on support frame 6, and 2 buckles 9 are fixed on the intermediate vertical bar of towing dolly 1, in being arranged above and below.
The telescopic rod 3 includes telescopic rod upper boom 301, telescopic rod connection sleeve 302, telescopic rod lower beam 303, telescopic rod
301 lower part of upper boom has left hand thread, and 303 top of telescopic rod lower beam has right-handed thread, and telescopic rod connects 302 side band of sleeve
There is the left hand thread cooperated with telescopic rod upper boom 301, the other end has the right-handed thread cooperated with telescopic rod lower beam 302.
The support rod 8 includes support rod upper boom 801, support rod connecting sleeve cylinder 802, support rod lower beam 803, support rod
