Abstract

The utility model relates to an electric tricycle for disabled and aged persons. The driving system of the electric tricycle adopts single-wheel drive, that is, a motor is connected with a drive worm-gear case through a transmission shaft; the drive worm-gear case is mounted on the shaft of a rear wheel; the carriage of the tricycle adopts a movable bottom board and a movable rear carriage board; the front end of the movable bottom board is hinged with the body of the tricycle, and the back end thereof is hinged with the front end of the movable rear carriage board; and a bottom plate lift control device enables the movable bottom board to rotate around a hinged support trunnion at the front end of the movable bottom board so as to lift and enables the rear carriage board to overturn around a hinged support trunnion between the rear carriage board and the movable bottom board horizontally. The utility model has the advantages of less labor, low speed, large restraint coefficient, safety, stability, and simple and convenient operation, and is an ideal travel tool for the people inconvenient in action such as the disabled and the aged to go on a journey.

Description

Residual old electro-tricycle

Technical field

The utility model belongs to technical field of transportation means, is specifically related to the electro-tricycle that a kind of disabled person of being suitable for and the elderly use.

Background technology

At present, the vehicle for deformed persons that uses for the disabled person roughly is divided into shaking wheelchair and electro-tricycle two big classes.Hand wheelchair speed is low, safety, but not laborsaving; Though existing electro-tricycle is laborsaving, only being suitable for degree of disability is not very big disabled person, because electro-tricycle requires the operator to get on or off the bus freely.

Summary of the invention

The purpose of this utility model provide a kind of laborsaving, speed is low, safety, and is suitable for the electro-tricycle that the bigger disabled person of degree of disability uses.

The utility model is to realize above-mentioned purpose by the following technical solutions: this residual old electro-tricycle, comprise headstock, front vehicle wheel, vehicle body, railway carriage and two rear wheels, its drive system adopts single wheel drive, be that electrical motor is connected with the driving worm case by transmission shaft, the driving worm case is installed on the axle of a rear wheel; Railway carriage adopts removable bottom and movable rearing-box plate, and the front end and the vehicle body of removable bottom is hinged, the front end of rear end and movable rearing-box plate is hinged; Make removable bottom keep flat upset around the hinging supporting shaft between itself and removable bottom by the base plate apparatus for controlling of lifting around its front end hinging supporting shaft rotation and lifting and movable rearing-box plate.

Can be more particularly, the base plate apparatus for controlling of lifting comprises a shaking wire rope pulley group, promptly be installed on the rocking bar on vehicle body one side successively, be installed on steel rope rolling worm case and steel rope rolling wheel hub under the rocking bar, be installed on the wire rope pulley of fixation side boxboard both upper ends thereof, be installed on the wire rope pulley at two ends, the removable bottom back lower place and be fixed on the steel rope gim peg on another piece fixation side boxboard top; The rearing-box plate that a projection respectively is installed in bottom, two fixation side boxboard rear ends is dug fulcrum, and the corresponding position at the anterior two ends of movable rearing-box plate is provided with rearing-box plate digs the matching used projection of fulcrum.

Because the utility model has adopted the single wheel drive of electrical motor and worm gear, can suppress speed effectively, strengthen hill climbing ability, and can increase brake factor when in the process of going up a slope, stopping, prevent that car from drawing back safety and stability.Again owing to adopted the structure of removable bottom and movable rearing-box plate, be used in combination hand base plate apparatus for controlling of lifting, base plate and rearing-box plate can be placed the level land, therefore lean on wheelchair-bound disabled person under the situation that does not need others to help, also can get on the bus, and then removable bottom and movable rearing-box plate shaken, the trip of can driving is gone sightseeing or shopping, has increased disabled person's the joy of life and the courage and the confidence of life greatly.The utility model safety and stability, easy and simple to handle, be handicapped disabled person and the elderly desirable walking-replacing tool when going on a journey.

Fig. 3 is the back view of the utility model embodiment;

Fig. 4 is the connection diagram of removable bottom and the movable rearing-box plate of the utility model embodiment.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the left side scheme drawing of the utility model embodiment, as seen from the figure, the drive system of this electro-tricycle adopts single wheel drive, the electrical motor 1 that promptly is installed on the railway carriage left side is connected with driving worm case 3 by transmission shaft 2, driving worm case 3 is double end worm gears, be installed on the axle of left back wheel, in order to drive wheel, because the characteristic of worm gear decision wheel can not slide under the electrical motor halted state forwards, backwards (in fact being exactly braking mode), so this car good braking effect, hill climbing ability is strong and be not easy to slide forwards, backwards.Railway carriage is made of the fixation side boxboard 6 of removable bottom 4, movable rearing-box plate 5 and the left and right sides, and the front end and the vehicle body of removable bottom is hinged, the front end of rear end and movable rearing-box plate is hinged, and shown in Figure 1 is the situation of removable bottom 4 when all putting down with movable rearing-box plate 5.

In conjunction with Fig. 2, the base plate apparatus for controlling of lifting comprises a shaking wire rope pulley group, promptly be installed on the rocking bar 7 on the vehicle body right side successively, be installed on steel rope rolling worm case 8 and steel rope rolling wheel hub 9 under the rocking bar, be installed on the wire rope pulley 10 of fixation side boxboard both upper ends thereof, be installed on the wire rope pulley 11 at two ends, the removable bottom back lower place and be fixed on the steel rope gim peg 12 on another piece fixation side boxboard top, realize the folding and unfolding of steel wire rope 13 by shaking rocking bar 7, thereby drive removable bottom 4 and rotate lifting around its front end hinging supporting shaft, wherein, steel rope rolling worm case 8 adopts the single head worm gears, makes steel rope can be parked in any firmly putting in the folding and unfolding process and non-slip.From Fig. 1 and Fig. 2 as seen, the rearing-box plate that a projection respectively is installed in bottom, two fixation side boxboard rear ends is dug fulcrum 14, in conjunction with Fig. 4, rearing-box plate is dug the projection 15 supporting uses of fulcrum 14 and corresponding position, the anterior two ends of movable rearing-box plate, when steel rope drive removable bottom rises to certain degree, movable rearing-box plate also and then rises, when the rearing-box plate of fixation side boxboard rear end bottom was dug fulcrum 14 and touched projection 15 on the movable rearing-box plate, movable rearing-box plate was just propped up the upset and the setting that turns forward slightly.Shown in Figure 2 is the just situation in switching process of movable rearing-box plate, and shown in Figure 3 then is overturn fully situation when erectting of movable rearing-box plate.

As can be seen from Fig. 2, between rocking bar and steel rope rolling worm case, be provided with rocking bar fulcrum 17, in order to fixing rocking bar 7.Be provided with self folding seat 16 at vehicle body middle part,, can remove self folding seat 16 when the driver is a push boat chair during to railway carriage.Electro-tricycle of the present utility model is provided with reversing gear, i.e. electrical motor counter-rotating drives wheel and rotates backward.
