Abstract
The invention discloses an omni-directional steering mechanism for an electric control wheelchair. A drive shaft (4) is vertically installed on a support frame through a shaft sleeve (10); a driving wheel (9) is installed at the bottom part of the drive shaft (4); a worm gear (5) is installed at the top part of the drive shaft (4); the worm gear (5) is meshed with a transverse worm (6); one end of the worm (6) is connected with a first gear shaft (11); a first chain gear (12) is installed on the first gear shaft (11); a second gear shaft (2) is installed on the support frame through forming a certain distance with the first gear shaft (11); a second chain gear (7) is installed on the second gear shaft (2); a chain (3) is wound on the first chain gear (12) and the second chain gear (7); and a handle (1) is connected with the second gear shaft (2). The omni-directional steering mechanism takes the chain, the worm gear and the worm as a combined steering mechanism, is a great improvement for people who have the weak ability to walk and can freely enter and go out of narrow spaces under the situation of not needing others to look after.
Description
Technical field
The present invention relates to steering mechanism, be specifically related to a kind of comprehensive steering mechanism of automatically controlled wheelchair.
Background technology
Increase along with the size of population, the intensification of aged tendency of population, person's a very big obstacle is exactly that walking ability weakens for advanced age, also may reach at last and can not walk, person at following advanced age is not only disability in this condition, but also the people who needs work capacity looks after them.The expert generally believes; this most populous country in whole world of China is faced with the population crisis that never met countries in the world; be the foreseeable future our country have the people's of work capacity quantity to reduce significantly, and need to look after advanced age the person number will increase.In order to save the labour force, allow the artificial country do contribution of work capacity create the wealth of society, just should make needs the person at advanced age, the physical disabilities person that look after to support oneself as far as possible at aspects such as clothing, food, lodging and transportion--basic necessities of life.Therefore based on such consideration, will develop the certain influence of generation to our the national future economy for the basic research and the product facility exploitation of this respect.
Summary of the invention
The objective of the invention is to: a kind of comprehensive steering mechanism of automatically controlled wheelchair is provided, and automatically controlled wheelchair is installed this omnirange steering mechanism, makes things convenient for person at advanced age, physical disabilities person to control wheelchair.
Technical solution of the present invention is: this comprehensive steering mechanism comprises handle, chain, driving shaft, worm gear, worm screw, wheel fork, driving wheel, gear shaft and sprocket, warp beam sleeve is vertically installed driving shaft on support, driving wheel is installed through wheel fork in the bottom of driving shaft, worm gear is installed at the top of driving shaft, the worm gear engagement is rack-mount worm screw laterally, the end of worm screw connects first gear shaft, first sprocket is installed on first gear shaft, first gear shaft is installed second gear shaft at interval on support, second sprocket is installed on second gear shaft, chain is wrapped on first sprocket and second sprocket, and handle is connected on second gear shaft.
When turning to, under the rotation of handle, drive the worm and gear transmission, rotate by worm gear drives driving wheel omnirange again, realize that the comprehensive of wheelchair turns to by chain.
The invention has the beneficial effects as follows: this combination steering mechanism based on chain, worm and gear realizes that omnibearing movable provides possibility, for the people a little less than the locomotor activity is great progress, the narrow space of can freely coming in and going out under the situation that need not others' treatment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 handle, 2 second gear shafts, 3 chains, 4 driving shafts, 5 worm gears, 6 worm screws, 7 second sprocket, 8 wheel forks, 9 driving wheels, 10 axle sleeves, 11 first gear shafts, 12 first sprocket.
The specific embodiment
As shown in Figure 1, this comprehensive steering mechanism comprises handle 1, chain 3, driving shaft 4, worm gear 5, worm screw 6, wheel fork 8, driving wheel 9, gear shaft and sprocket, the warp beam sleeve 10 vertical driving shafts 4 of installing on support, driving wheel 9 is installed through wheel fork 8 in the bottom of driving shaft 4, worm gear 5 is installed at the top of driving shaft 4, worm gear 5 engagements are rack-mount worm screw 6 laterally, the end of worm screw 6 connects first gear shaft 11, first sprocket 12 is installed on first gear shaft 11, first gear shaft 11 is installed second gear shaft 2 at interval on support, second sprocket 7 is installed on second gear shaft 2, chain 3 is wrapped on first sprocket 12 and second sprocket 7, and handle 1 is connected on second gear shaft 2.
When turning to, turning handle 1 drives 7 rotations of second sprocket, drives first sprocket 12 by chain 3 and rotates, and first sprocket 12 drives worm screw 6 by first gear shaft 11 and rotates, worm screw 6 and worm gear 5 engagements drive worm gear 5 rotations, and worm gear 5 rotations drive driving wheel 9 and rotate.
