Abstract
An elderly wheelchair capable of avoiding collision comprises a sitting plate of the elderly wheelchair. A pair of cotton pads is bundled on the surface of the front portion of the sitting plate of the elderly wheelchair and the surface of the rear portion of the sitting plate of the elderly wheelchair respectively, a strip-shaped rod penetrates through each cotton pad, and in addition, one end of each cotton pad is connected with the external surface of the corresponding strip-shaped rod. A fluid container filled with compressible fluid is connected with one end of a pipeline, the pipeline is provided with a hydraulic valve, and the other end of the pipeline is connected with a fluid through hole of a hydraulic cylinder. A proximity switch is arranged in front of the sitting plate of the elderly wheelchair, a pushing rod of the hydraulic cylinder is connected with a pair of strip-shaped rods through a pair of riveting pieces respectively, and the proximity switch and the hydraulic valve are both connected with a power supply unit of the hydraulic valve. By the adoption of the structure, the elderly wheelchair capable of avoiding collision can overcome the defect that if two or more elderly wheelchairs appear at the corner at present, the danger that the collision probability of the elderly wheelchairs is increased can exist.
Description
Technical field
The invention belongs to geriatric wheelchair device technique field, be specifically related to a kind of geriatric wheelchair avoiding colliding.
Background technology
To block up place geriatric wheelchair inside in people at present more; usually the deflecting roller being all through bottom rolls to implement the adjustment of various direction with this; the old people on seat just can be allowed to run by means of such framework; nonetheless because people blocks up in place more; often there will be corner; and old people takes action reaction inconvenience, if there is the geriatric wheelchair of more than two appear at corner, the danger of the probability increase that geriatric wheelchair collides will be there is.
Summary of the invention
Object of the present invention provides a kind of geriatric wheelchair avoiding colliding, comprise the seat of geriatric wheelchair, a pair of Cotton Gossypii pad is banded in the surface at the rear of the surface in the front of the seat of geriatric wheelchair and the seat of geriatric wheelchair respectively, this Cotton Gossypii pad is passed by strip rod respectively, an end of Cotton Gossypii pad is connected with this strip rod outer surface in addition, an end of the flow container and pipeline that contain compressible fluid is connected, pipeline is arranged hydraulic valve, another end of pipeline and the fluid through-hole of hydraulic cylinder are connected, in the front of the seat of geriatric wheelchair, proximity switch is set, the promotion rod of hydraulic cylinder is connected with a pair of strip rod respectively by a pair of riveting parts, proximity switch and hydraulic valve are all connected with the power supply unit of hydraulic valve.If such structure avoid existing there is the geriatric wheelchair of more than two appear at corner, the defect of the danger of the probability increase that geriatric wheelchair collides will be there is.
In order to overcome deficiency of the prior art, the invention provides a kind of solution avoiding the geriatric wheelchair of colliding, specific as follows:
A kind of geriatric wheelchair avoiding colliding, comprise the seat 1 of geriatric wheelchair, a pair of Cotton Gossypii pad 2 is banded in the surface at the rear of the surface in the front of the seat 1 of geriatric wheelchair and the seat 1 of geriatric wheelchair respectively, this Cotton Gossypii pad 2 is passed by strip rod 3 respectively, an end of Cotton Gossypii pad 2 is connected with this strip rod 3 outer surface in addition, an end of the flow container 4 and pipeline 5 that contain compressible fluid is connected, pipeline 5 is arranged hydraulic valve 6, another end of pipeline 5 and the fluid through-hole of hydraulic cylinder 7 are connected, in the front of the seat 1 of geriatric wheelchair, proximity switch 8 is set, the promotion rod 9 of hydraulic cylinder 7 is connected with a pair of strip rod 3 respectively by a pair of riveting parts 10, proximity switch 8 and hydraulic valve 6 are all connected with the power supply unit 9 of hydraulic valve.
The sweep limits of described proximity switch 8 is 150CM-300CM.
Described hydraulic cylinder 7 is bidirectional hydraulic cylinder.
Apply such scheme of the present invention, if proximity switch 8 gets barrier in sweep limits, then with by power supply unit 9 conducting of hydraulic valve 6 with hydraulic valve, therefore just the fluid of the high-power firing rate being filled with the flow container 4 of compressible fluid can be led feed liquor air cylinder 7, make to promote rod 9 to link with riveting parts 10, avoid colliding.
Accompanying drawing explanation
Figure l is the structural representation of left part of the present invention.
Fig. 2 is the structural representation of front portion of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, summary of the invention is described further:
Shown in seeing figures.1.and.2, avoid the geriatric wheelchair of colliding, comprise the seat 1 of geriatric wheelchair, a pair of Cotton Gossypii pad 2 is banded in the surface at the rear of the surface in the front of the seat 1 of geriatric wheelchair and the seat 1 of geriatric wheelchair respectively, this Cotton Gossypii pad 2 is passed by strip rod 3 respectively, an end of Cotton Gossypii pad 2 is connected with this strip rod 3 outer surface in addition, an end of the flow container 4 and pipeline 5 that contain compressible fluid is connected, pipeline 5 is arranged hydraulic valve 6, another end of pipeline 5 and the fluid through-hole of hydraulic cylinder 7 are connected, in the front of the seat 1 of geriatric wheelchair, proximity switch 8 is set, the promotion rod 9 of hydraulic cylinder 7 is connected with a pair of strip rod 3 respectively by a pair of riveting parts 10, proximity switch 8 and hydraulic valve 6 are all connected with the power supply unit 9 of hydraulic valve.The sweep limits of described proximity switch 8 is 150CM-300CM, and this scanning area can realize prevention ahead of time.Described hydraulic cylinder 7 is bidirectional hydraulic cylinder, and such shuttling movement, buffering effect is better.
Apply such scheme of the present invention, if its operation principle gets barrier for proximity switch 8 in sweep limits, then with by power supply unit 9 conducting of hydraulic valve 6 with hydraulic valve, therefore just the fluid of the high-power firing rate being filled with the flow container 4 of compressible fluid can be led feed liquor air cylinder 7, make to promote rod 9 to link with riveting parts 10, avoid colliding.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to technical spirit of the present invention, within the spirit and principles in the present invention, to any simple amendment that above embodiment is done, equivalent replacement and improvement etc., within the protection domain all still belonging to technical solution of the present invention.
