Abstract

The utility model belongs to a special walking vehicle for old people and patients with handicapped legs. The utility model is characterized in that the utility model is electrically driven, and walks on caterpillar bands. A rubber block is inlaid at the side of the caterpillar band to cause a vehicle body to run smoothly, and the side of the caterpillar band is contacted with the ground. Noise is reduced, and road surfaces are protected. The utility model uses a direct current power supply as power, has no pollution, and is easy to manipulate. The vehicle body is provided with a hydraulic booster and an electromagnetic clamping hook, and the climbing power is increased. The hydraulic booster can further enhance the capacity for going upstairs and downstairs and climbing slopes. The special walking vehicle can be directlly operated by old people and patients with handicapped legs to go upstairs and downstairs and do outdoor activities.

Description

The car of riding instead of walk

Technical field

This utility model relates to a kind of personal car of riding instead of walk, and particularly the people with disability and the old people of shank forfeiture locomotor activity use car.

Background technology

The existing in the market car of riding instead of walk all is to be ground-engaging element with the wheel, and it lacks the function of crossing over ditch and climbing the building, and existing stairs-mover security performance is relatively poor, takes the people and can not independently use.Along with the development of China's urban construction, most of people building of having lived has brought a lot of inconvenience meanwhile also for old people and shank people with disability's trip.

Summary of the invention

The purpose of this utility model provides a kind of electric bicycle, and it can stride across little ditch, and can go up downstairs voluntarily by taking the people.

The purpose of this utility model is to realize like this, chargeable bottle and motor are arranged in car body, on the handrail of seat, switch is installed, can control starting, turn to and skidding of the car of riding instead of walk, the running gear crawler type, there is driving wheel at the rear portion of car, and there is bogie wheel at the middle part, and forward bogie wheel is raised in order to climbing.Its structure and tank class seemingly, the crawler belt outside can install block rubber additional.

This car of riding instead of walk is in order to increase the ability of climbing and stair activity, oil pump is arranged in car body, the rear section of seat has three pump switch handles, control two of car body one side respectively forward and the hydraulic pressure chest expander that stretches out backward for two, its end is equipped with the electromagnetism grab, during stair activity, Ka Gou and banister are blocked, drive the car stair activity of riding instead of walk when the hydraulic pressure chest expander is flexible and move, help motor-driven caterpillar tracks to rotate, replenish the deficiency of car body direct current generator driving force.Simultaneously, front and back chest expander alternately used runs without interruption to guarantee car body, and when car body overload or the gradient are big, can also move simultaneously with increase thrust by former and later two chest expanders; If still move the power deficiency, can enable the hydraulic booster of the tailstock again, the start and stop of the 3rd pump switch handle control hydraulic booster, work when hydraulic booster moves forward by car body is when one group of hydraulic press is vertical with ground (stair), just can annotate pressure automatically raises car body, dwindle the tilting of car body degree, promote that vehicle body moves forward, along with the car body reach, hydraulic press recedes gradually and reclaims stroke lever, meanwhile, the gear mechanism motion by being associated makes to be organized hydraulic press separately and moves to vehicle body lower support car body, when vertical once more with ground (stair), just begin again to annotate and press, vehicle body is raise, and car body continues forward, goes round and begins again with this, just can reach the up purpose of power-assisted, in the time of downstairs, allow the motor slow rotation, the control brake, while hydraulic pressure chest expander remains unchanged and railing blocks, and slowly annotates to press to make vehicle body steadily descending.

This utility model by driven by power, stud with the crawler travel of block rubber; so noise is little, pollution-free, easy to operate; operate steadily; the protection road surface; stronger climbing capacity is arranged, add hydraulic pressure chest expander and the electromagnetism grab above it, can go up downstairs by taking people oneself; and hydraulic booster has more been strengthened upstairs and gradeability, thereby makes old people and shank crippled can handle downstairs and arrive outdoor activity voluntarily.

Description of drawings

Accompanying drawing is an embodiment schematic side view of the present utility model.

The specific embodiment

On the front end handrail of seat (3), the electric motor starting shutdown switch is installed and car body turns to, brake switch (2), be equipped with forward and backward two hydraulic pressure chest expanders (4) at the sidepiece of car body, their front end has electromagnetism grab (1), the storage battery (5) at car body middle part adopts chargeable storage battery, the outlet of oil pump (6) divides three the tunnel to lead to hydraulic pressure chest expander (4) and hydraulic booster (9) preceding and backward, it is by three pump switch handles (7) control, and two hydraulic booster wheels are arranged at the bottom of hydraulic booster (9).Two direct current generators (not drawing among the figure) are equipped with in car body inside, drive two driving wheels (8) about rear vehicle respectively, about the walking of each three bogie wheel (11) on crawler belt (10), there is seat (3) pedal (12) in the Herba Plantaginis portion of riding instead of walk.

Claims

1. car of riding instead of walk, it has seat (3), running gear (10), it is characterized in that there is handrail (2) seat (3) front portion, storage battery (5) is arranged in the car body, and running gear (10) is a crawler type, and it is driven by driving wheel (8), mainly by bogie wheel (11) supported cart body weight, the start and stop that can control the car of riding instead of walk are housed on the handrail (2), turn to and arresting switch.

2. the car of riding instead of walk according to claim 1, it is characterized in that having in the car body oil pump (6), there are three pump switch handles (7) in the rear flank portion of seat (3), wherein before two side direction of controlling car body respectively and the hydraulic pressure chest expander (4) that stretches out backward, all there is electromagnetism grab (1) end of this chest expander, can block banister.

3. according to claim 1, the 2 described cars of riding instead of walk, it is characterized in that rear vehicle is equipped with hydraulic booster (9), it is made of the roller of be mutually related two hydraulic component and its underpart, two groups of hydraulic press start and stop of the 3rd pump switch handle (7) control and alternate run.
