Description
What this utility model related to is a kind of Wheel-chair of taking turns.
Tricycle in the prior art, carriage and wheelchair go-cart are the vehicles of widespread, tricycle, carriage mainly are to utilize steering wheel or handle to turn to, the place ahead that vehicle frame is all placed in steering wheel, handle installation site, convenient, flexible in driving process, but this tricycle, carriage are because steering is installed in the place ahead of vehicle frame, taken the activity that segment space is unfavorable for the driver, especially the people of lower limb disability not only needs the walking instrument but also can make things convenient for use by seat in life; Though and existing wheelchair go-cart made things convenient for the people with disability up and down and operation, the steering of wheelchair go-cart is to adopt universal wheel to turn to, it can't be fit to install operating rapidly turning to behind the driving device, driving that can only be by manpower and turning to; In addition, the steering structure complexity of above-mentioned tricycle, carriage, defective such as consumptive material is many, volume is big repair inconvenience, and active spatial dimension is less, and the cost height.
The purpose of this utility model is to be to provide the wheel Wheel-chair that a kind of steering behaviour is good, easy for going up and down, enforcement is stable.
The purpose of this utility model realizes by following technical scheme, this is taken turns Wheel-chair and comprises vehicle frame, steering mechanism, steering mechanism is provided with driving link and driven member, the connecting rod that is provided with on steering mechanism's driving link passes vehicle frame and connects with an end of armed lever, it is exactly can operate easily on vehicle frame with hands for the driver that armed lever is set, armed lever laterally rotates around the interface that armed lever connects with connecting rod, armed lever can vertically rotate with interface, can utilize the rocking bar transmission on steering mechanism's driven member, pitman arm links to each other with connecting rod on the driving link, the handrail arm that connecting rod can pass on the vehicle frame links to each other with an end of armed lever, carry out transmission by steering linkage between pitman arm and the knuckle arm, pitman arm links to each other with connecting rod, can be set to two connecting rods on the driving link passes the handrail arm respectively and links to each other with armed lever, connecting rod is provided with rocking bar, is connected with pull bar between rocking bar and the rocking bar.Can utilize gear drive on steering mechanism's driven member, the connecting rod other end on the driving link is connected with the gears engaged of an end on gear and the main shaft, the engagement that cogs of the gear of the other end of main shaft and knuckle arm.On vehicle frame protective cover can be installed, protective cover can be foldable canopy.
This utility model is compared with prior art has following several advantage, the first, this steering of taking turns Wheel-chair is different with the steering installation site of existing wheel Wheel-chair, this utility model steering mechanism can be installed in holding up on the arm of vehicle frame, reduce and take the vehicle frame front space, be convenient to get on or off the bus, and the interface that connects with connecting rod around armed lever by armed lever of this steering laterally rotates and spurs the connecting rod drive and turn to, and steering behaviour is good, and is very convenient.The second, can motor-drivenly drive the characteristics of sailing for the ease of this car of operational drive in conjunction with existing tricycle, carriage and wheelchair go-cart space is big, convenience operation, produce to have and motor-drivenly to drive the wheel Wheel-chair of sailing, operate steadily, take up room little, it is particularly suitable that this device is directed to the people of loin, legs and feet inconvenience, and the chair that can be used as in the life is used.Three, took turns turning to of Wheel-chair is to adopt steering wheel or handle in the past, and this utility model adopts armed lever laterally to rotate the pulling connecting rod and turns to, and is convenient, flexible, laborsaving.The wheel Wheel-chair that this apparatus structure is simple, volume is little, the running space scope is wide.
The utility model is described in further detail with accompanying drawing in conjunction with the embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a rocker gear sketch map of the present utility model.
Fig. 3 is this utility model gear drive structural representation.
From Fig. 1, Fig. 2 as can be seen, this is taken turns Wheel-chair and comprises vehicle frame 1, steering mechanism, steering mechanism is provided with driving link and driven member, connecting rod 2 on steering mechanism's driving link passes on the vehicle frame 1 and connects with an end of armed lever 3, the other end of armed lever 3 is connected with perpendicular handle 15, the interface that armed lever 3 connects with connecting rod 2 around armed lever 3 laterally rotates the drivening rod rotation, armed lever 3 can vertically rotate with interface armed lever 3 is close proximity on the seat 10, on steering mechanism's driven member rocker gear can be set, mainly by pitman arm 4, knuckle arm 5, steering linkage 6 is formed, pitman arm 4 links to each other with connecting rod 2 on the driving link, the handrail arm that connecting rod 2 can pass on the vehicle frame 1 links to each other with an end of armed lever 3, and the other end of armed lever 3 is connected with perpendicular handle 15; Carry out transmission by steering linkage 6 between pitman arm 4 and the knuckle arm 5, to make armed lever 3 be that the center of circle laterally rotates with the interface of connecting rod 2 and armed lever 3 by pulling perpendicular handle 15, force connecting rod 2 to rotate, pitman arm 4 deflections pulling steering linkage 6 on the drivening rod, the knuckle arm 5 that connects with steering linkage also changes to carry out and turns to, two connecting rods 2 can be set on the driving link to be passed the handrail arm respectively and links to each other with armed lever 3, connecting rod is provided with rocking bar 7,8, be connected with pull bar 9 between rocking bar 7 and the rocking bar 8, be to turn to synchronously in order to keep like this, both hands can be controlled steering mechanism simultaneously.
On Fig. 3, can utilize gear drive on steering mechanism's driven member, the connecting rod other end on the driving link is connected with bevel gear 12 engagements of an end on bevel gear 11 and the main shaft, and bevel gear 14 engagements turn on the bevel gear 13 of the other end of main shaft and the knuckle arm.In addition, for safe driving better, on vehicle frame protective cover can be installed, protective cover is made foldable canopy also can make other shape.
