Abstract
The invention provides an intelligent trolley comprising handlebars and a plurality of wheel units. The intelligent trolley further comprises a processing unit, a flexible touch sensor electrically connected with the processing unit, an acceleration sensor and a plurality of automatic brake units; the flexible touch sensor is disposed on one handlebar; the processing unit judges whether or not the trolley is held by a user according to a sensing signal of the flexible touch sensor, judges whether or not the trolley is in motion according to a signal generated by the acceleration sensor and controls the automatic brake unit to lock the wheel units in a safe braking manner when the trolley is in motion. When monitored by nobody and moving, the intelligent trolley is automatically braked in the safe braking manner, and safety of a baby or articles on the trolley is protected.
Description
Technical field
The present invention relates to a kind of handbarrow, particularly to a kind of smart cart.
Background technology
In the modern life, baby stroller has become as the thing of the indispensability that each has baby family.When outgoing, great Ren You

And when forgetting baby stroller brakes, baby stroller be possible to because by other people neglectful collision and slide, this
Situation will cause danger to baby.
Content of the invention
In view of this, the present invention provides a kind of smart cart, to solve above-mentioned technical problem.
A kind of smart cart, described handbarrow includes handrail and multiple wheel unit, and described handbarrow also includes processing
Unit and the flexible touch sensor electrically connecting with described processing unit, acceleration transducer and multiple self-actuating brake unit, institute
State flexible touch sensor to be arranged on described handrail, the signal that described processing unit senses according to described flexible touch sensor
Judge described handbarrow nobody when helping, judge whether described handbarrow is according to the signal that described acceleration transducer produces
Kinestate, and when described handbarrow is kept in motion, control described self-actuating brake unit in a safety shut-down mode
Pin described wheel unit.
In the present invention, in handbarrow no worker monitor and when moving, brake is automatically carried out in safety shut-down mode,
Safety with the baby on protection handbarrow or article.
Brief description
Fig. 1 is the three-dimensional view of smart cart in one embodiment of the present invention.
Fig. 2 is the functional block diagram of smart cart in one embodiment of the present invention.
Fig. 3 is the schematic diagram of the self-actuating brake unit in Fig. 1 in one embodiment of the present invention, illustrates self-actuating brake list
Wheel pins in unit.
Fig. 4 is another schematic diagram of the self-actuating brake unit in Fig. 1 in one embodiment of the present invention, illustrates automatic brake
Car unit does not pin wheel.
Main element symbol description
Following specific embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Specific embodiment
Refer to Fig. 1 and Fig. 2, the smart cart 100 in present embodiment can be baby stroller, goods handbarrow
Deng.Handbarrow 100 is included car body 10, handrail 11, multiple wheel unit 12, processing unit 13 and is electrically connected with processing unit 13
Flexible touch sensor 14, acceleration transducer 15, self-actuating brake unit 16 and alarm unit 17.Certainly, handbarrow 100 also wraps
Include and power for processing unit 13, flexible touch sensor 14, acceleration transducer 15, self-actuating brake unit 16 and alarm unit 17
Power supply unit 18.Power supply unit 18 can be solar panel etc..In the present embodiment, flexible touch sensor 14 is arranged
On handrail 11, for sensing whether handrail 11 is touched by people.Self-actuating brake unit 16 is arranged in wheel unit 12.Process single
The position of unit 13, acceleration transducer 15 and alarm unit 17 can be configured according to practical situation.For example, by processing unit 13
It is arranged on the bottom of car body 10.Acceleration transducer 15 is arranged in wheel unit 12, and alarm unit 17 is arranged on car body 10
Sidepiece.
In the present embodiment, when processing unit 13 according to the signal that flexible touch sensor 14 senses judge currently without
When people helps handrail 11, alarm unit 17 is controlled to be reported to the police, dangerous with this handbarrow 100 of people of reminding surrounding.Report to the police
Unit 17 can be voice output (as loudspeaker) and/or light-emitting device (led) etc..
Processing unit 13, also when nobody helps handrail 11, judges handbarrow according to the signal of acceleration transducer 15 sensing
Whether 100 be currently kept in motion.When handbarrow 100 is kept in motion, processing unit 13 controls self-actuating brake unit
16 pinning wheel unit 12, to stop handbarrow 100 from continuing motion.In order to ensure the safety of the baby in handbarrow 100 or keep away
Exempt from dropping of article in handbarrow 100, self-actuating brake unit 16 is stopped using point in brake or gradually strengthened the sides such as brake power
Formula, makes the movement velocity of handbarrow 100 slowly reduce.Processing unit 13 judges always according to the signal that acceleration transducer 15 senses
After handbarrow 100 stop motion one preset time period, control self-actuating brake unit 16 release wheel unit 12, so that handbarrow
100 can promote.I.e. after handbarrow 100 stop motion preset time period, handbarrow 100 may be in a safe condition, example
As someone's control, now, releasable wheel unit 12, to ensure that handbarrow 100 can be promoted.
Self-actuating brake unit 16 can be existing any brake gear that can apply on handbarrow 100.As Fig. 3-4 institute
Show, in the present embodiment, each wheel unit 12 includes two wheels 121, and handbarrow 100 includes multiple self-actuating brake units
16, each self-actuating brake unit 16 is disposed therein in a wheel unit 12.Each self-actuating brake unit 16 includes being arranged at two
Two holding blocks 161 between individual wheel 121.Two holding blocks 161 can do opposite and opposite motion.When two holding blocks 161
It is (Fig. 4) when move toward one another makes two holding blocks 161 not support with two wheels 121, handbarrow 100 can be promoted.When two
Individual holding block 161 is done and moves to when being supported with two wheels 121 (Fig. 3) opposite to each other, and due to rubbing action, handbarrow 100 can be slow
Slow down up to stop motion.
Certainly, handbarrow 100 may also include hand-operated brake unit (not illustrated).In case of emergency, user can pass through handss
Dynamic brake units are braked.
In the present embodiment, when handbarrow 100 is in no worker monitor, can be carried out by modes such as sound and/or light
Report to the police, dangerous with this handbarrow 100 of people of reminding surrounding.Further, this handbarrow 100 also in no worker monitor and moves
When, brake is automatically carried out in safety shut-down mode, to protect the safety of baby on handbarrow 100 or article.
