Abstract
The present invention relates to a kind of intelligent wheel chair traveling obstacle crossing devices, including obstacle detouring sensing device and obstacle lifting apparatus；The obstacle detouring sensing device includes the bumper connecting with wheelchair driving front-wheel, the reed that connector, the connector being connected with bumper are connected and the strain transducer being arranged on reed；The obstacle lifting apparatus includes support wheel, the connecting rod connecting with support wheel and connect electronic tie rod with connecting rod；The strain transducer is obstructed, and simultaneously transport processor handles starting obstacle lifting apparatus work after analysis to signal.The present invention can easily cross the barrier (including pitfall) of drop about 10cm or so, and wheelchair travel condition is steady；It is not only low in cost, securely and reliably, and also it is durable.
Description
Technical field
The present invention relates to a kind of intelligent wheel chair traveling obstacle crossing devices.
Background technique
Currently, China just carries out various technological innovations in terms of wheelchair intellectualized technology, function is gradually perfect.According to me
State's technology standard requirements, the wheelchair maximum obstacle that can pass through 10cm drop, this general index during traveling will cause
The increase (as reached 30cm) of preceding wheel diameter, this will cause wheelchair substantially to jolt to actual conditions, or even have the danger of overturning.
Summary of the invention
The technical problem to be solved by the present invention is proposing a kind of intelligent wheel chair traveling obstacle crossing device, set by structure optimization
Meter and automatic control, preferably realize steady obstacle detouring, promote China's wheelchair intelligent level.
The technical scheme adopted by the invention is as follows: a kind of intelligent wheel chair traveling obstacle crossing device, including obstacle detouring sensing device and
Obstacle lifting apparatus；The obstacle detouring sensing device includes the anti-vibration bar connecting with wheelchair driving front-wheel, is connected with anti-vibration bar
Connector, the reed that connector is connected and the strain transducer being arranged on reed；The obstacle lifting apparatus packet
Include support wheel, the connecting rod connecting with support wheel and the electronic tie rod connecting with connecting rod；The strain transducer is obstructed
Starting obstacle lifting apparatus work after signal and transport processor processing analysis.
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.
It further says, when front-wheel of the present invention meets barrier, moves ahead and be obstructed, anti-vibration bar is bent reed by connector, answers
Become sensor therewith to send out signal, be analyzed for processor processing.
Further, one end of connecting rod of the present invention connects support wheel, and the other end connects one end of electronic tie rod, turns
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 present invention are: the present invention can easily cross the barrier (including pitfall) of drop about 10cm or so,
Wheelchair travel condition is steady；It is not only low in cost, securely and reliably, and also it is durable.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the dirtier sensing device of the present invention；
Fig. 2 is the structural schematic diagram of obstacle lifting apparatus of the present invention；
In figure: 1, universal front-wheel；2, anti-vibration bar；3, connector；4, reed；5, strain transducer；6, support wheel；7, even
Bar；8, electronic tie rod.
Specific embodiment
Presently in connection with attached drawing and preferred embodiment, the present invention is described in further detail.These attached drawings are simplified
Schematic diagram, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
A kind of intelligent wheel chair traveling obstacle crossing device, including obstacle detouring sensing device and obstacle lifting apparatus.
Obstacle detouring sensing device as shown in Figure 1, strain transducer is fixed on reed, be fixed on wheelchair by reed one end,
The other end is connected by connector with front-wheel anti-vibration bar；When front-wheel meets barrier, moves ahead and be obstructed, anti-vibration bar keeps reed curved by connector
Song, strain transducer therewith send out signal, analyze for processor processing.
For obstacle lifting apparatus as shown in Fig. 2, connecting rod one end connects support wheel, the other end connects 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 processing analysis
Know that obstacle lifting apparatus starts, wheelchair is lifted by support wheel, makes front-wheel by electronic tie rod movement, exactly this branch link rotatable
It surmounts obstacles, after strain transducer blackout, processor will notify electronic tie rod to pack up support wheel.
It is a specific embodiment of the invention described in above instructions, various illustrations are not to reality of the invention
The limitation of matter Composition of contents, person of an ordinary skill in the technical field can be to described in the past specific after having read specification
Embodiment is made an amendment or is deformed, without departing from the spirit and scope of the invention.
