Abstract
The invention relates to an intelligent wheelchair traveling obstacle crossing device which comprises an obstacle crossing sensing device and an obstacle lifting device; the obstacle crossing sensing device comprises a shock-absorbing rod connected with a driving front wheel of the wheelchair, a connector connected with the shock-absorbing rod, a reed connected with the connector and a strain sensor arranged on the reed; the obstacle lifting device comprises a supporting wheel, a connecting rod connected with the supporting wheel and an electric pull rod connected with the connecting rod; and the strain sensor receives the obstruction signal and transmits the obstruction signal to a processor for processing and analyzing, and then the obstacle lifting device is started to work. The wheelchair can easily cross obstacles (including pits) with the fall of about 10cm, and the wheelchair is stable in running state; not only has low cost, safety and reliability, but also is durable.
Description
Technical field
The present invention relates to a kind of intelligent wheel chair traveling obstacle crossing device.
Background technology
At present, China just carries out various technological innovations in terms of wheelchair intellectualized technology, and function is gradually perfect.According to me
The requirement of state technical standard, wheelchair is maximum during traveling will be caused by the obstacles of 10cm drops, this general index
The increase (as reached 30cm) of preceding wheel diameter, this will cause wheelchair significantly to jolt to actual conditions, or even have the danger of overturning.
The content of the invention
The technical problem to be solved in the present invention is：A kind of intelligent wheel chair traveling obstacle crossing device is proposed, is set by structure optimization
Count and automatically control, preferably realize steady obstacle detouring, lifting China wheelchair intelligent level.
The technical solution adopted in the present invention is：A kind of intelligent wheel chair traveling obstacle crossing device, including obstacle detouring sensing device and
Obstacle lifting apparatus；Described obstacle detouring sensing device includes driving bumper that front-wheel is connected with wheelchair, is connected with bumper
Connector, the reed that connector is connected and the strain transducer being arranged on reed；Described obstacle lifting apparatus bag
Include support wheel, the connecting rod being connected with support wheel and be connected electronic tie rod with connecting rod；Described strain transducer is obstructed letter
Number and transport processor Treatment Analysis after start the work of obstacle lifting apparatus
Further, strain transducer of the present invention is fixed on reed；Wheel is fixed in one end of the reed
On chair, the other end is connected by connector with anti-vibration bar.
Further say, when front-wheel of the present invention meets barrier, move ahead and be obstructed, anti-vibration bar bends reed by connector, should
Become sensor therewith to send out signal, for processor Treatment Analysis.
Further, one end connection support wheel of connecting rod of the present invention, the other end connects one end of electronic tie rod, turned
Activity supporting point is fixed on wheelchair；The other end of the electronic tie rod is connected on wheelchair.
Further, electronic tie rod of the present invention is rotatably arranged on wheelchair.
The beneficial effects of the invention are as follows：The present invention can easily cross drop about 10cm or so barrier (including pitfall),
Wheelchair travel condition is steady；It is not only with low cost, safe and reliable and durable in use.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the dirtier sensing device of the present invention；
Fig. 2 is the structural representation of obstacle lifting apparatus of the present invention；
In figure：1st, universal front-wheel；2nd, bumper；3rd, connector；4th, reed；5th, strain transducer；6th, support wheel；7th, even
Bar；8th, electronic tie rod.
Embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further detailed explanation.These accompanying drawings are simplified
Schematic diagram, only illustrates the basic structure of the present invention in a schematic way, therefore it only shows the composition relevant with the present invention.
A kind of intelligent wheel chair traveling obstacle crossing device, including obstacle detouring sensing device and obstacle lifting apparatus.
Obstacle detouring sensing device is as shown in figure 1, strain transducer is fixed on reed, and reed one end is fixed on wheelchair,
The other end is connected by connector with front-wheel anti-vibration bar；When front-wheel meets barrier, move ahead and be obstructed, anti-vibration bar makes reed curved by connector
Song, strain transducer therewith sends out signal, for processor Treatment Analysis.
Obstacle lifting apparatus is as shown in Fig. 2 connecting rod one end connects support wheel, other end connection electronic tie rod, fixed pivot
In on wheelchair；The electronic tie rod other end is connected on wheelchair and (is rotatably connected).Strain transducer signal leads to after Treatment Analysis
Know that obstacle lifting apparatus starts, electronic tie rod action, exactly this branch link rotatable, by support wheel by wheelchair lifting, make front-wheel
Surmount obstacles, after strain transducer blackout, processor will notify electronic tie rod to pack up support wheel.
The embodiment of the simply present invention described in description above, the reality of various illustrations not to the present invention
Matter Composition of contents is limited, and person of an ordinary skill in the technical field can be to described in the past specific after specification has been read
Embodiment is made an amendment or deformed, without departing from the spirit and scope of the invention.
