Description
Technical field
The present invention relates to wheel-chair service brake performance testing device, belong to brake performance technical field of measurement and test.
Background technology
The existing the elderly of China more than 200,000,000, wherein about 6,500,000 people are old dementia patients.In addition, China has more than 4,000 ten thousand
Diabetic, wherein nearly 4,000,000 people of concurrent lower limbs necrosis disease person.In addition, it is annual newly-increased because traffic accident, industrial injury, other surprisingly etc.
Cause the people of lower limb the disabled about 500,000.In 50 years from now on, the population ratio of more than 60 years old is estimated to double, simultaneously because various
The physical disabilities that disaster and disease are caused also are increasing year by year, and they have different degrees of Disability, such as walking, eyesight,
Start and language etc..This is a huge and special colony, is the weak person of society, it is necessary to the love of the whole society.And wheel-chair
It is not only the walking-replacing tool of the elderly and walking function obstacle person (paraplegia or patients with cerebral palsy) superior performance, it is often more important that they
Physical exercise can be carried out by means of wheel-chair and social activities is participated in, so that improve freedom of action degree and be socially reintegrated again, because
This wheel-chair belongs to important rehabilitation instrument.
The service brake of wheel-chair has a major impact to its security performance, especially rehabilitation wheelchair car, and its occupant is past
It is not quick enough toward reaction, when running into emergency situations, the stopping if wheel-chair can not brake in time, it will caused to passenger
Injury.Therefore, in order to ensure the safety of wheel-chair user, it is to pass that the service brake of wheel-chair, which is tested and evaluated,
Important.
The content of the invention
It is reasonable in design, make it is an object of the invention to the defect for prior art and not enough there is provided one kind is simple in construction
With convenient wheel-chair service brake performance testing device.
To achieve the above object, the technical solution adopted by the present invention is：It includes test platform housing, and outside test platform
The test platform that frame bottom is connected by rotating shaft, is fixed on the digital display angle measuring instrument of the outer frame bottom of test platform, is located at survey
The ultrasonic baffle plate of platform bottom is tried, gas spring and its triangular support bracket that test platform front portion is connected with platform housing are to be measured
Wheel-chair, and the ultrasonic distance measuring apparatus that can be fixed on wheel-chair.
During test, the top of test platform is risen to after required height by gas spring, locking gas spring, so that test
Platform can be determined with the horizontal certain angle, the angle value by digital display angle measuring instrument.Ultrasonic distance measuring apparatus is fixed on
On wheel-chair to be measured, and wheel-chair is placed on test platform top, wheel-chair will start to glide.When it reaches certain speed
When, the brake for opening wheel-chair opens ultrasonic distance measuring apparatus simultaneously, and in the presence of brake, wheel-chair will taper off fortune
It is dynamic.Ultrasonic distance measuring apparatus can record wheel-chair self-retention automatically and start to it to stop travelled distance, the distance value and survey completely
The angle value tried between platform and horizontal plane will be used as the major parameter foundation for evaluating wheel-chair service brake performance.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this

Description of reference numerals：
Test platform housing 1；Test platform 2；Digital display angle measuring instrument 3；Ultrasonic baffle plate 4；Gas spring 5；
And its triangular support bracket 6；Wheel-chair 7 to be measured；Ultrasonic distance measuring apparatus 8.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Referring to such as Fig. 1 -- shown in Fig. 4, including test platform housing 1, it is connected with the bottom of test platform housing 1 by rotating shaft
The test platform 2 connect, is fixed on the digital display angle measuring instrument 3 of the bottom of test platform housing 1, is located at the super of the bottom of test platform 2
Sound baffle plate 4, the anterior gas spring 5 and its triangular support bracket 6 being connected with platform housing 1 of test platform 2, wheel-chair 7 to be measured, with
And the grade part of ultrasonic distance measuring apparatus 8 on wheel-chair can be fixed on.
Specific test process is as follows：
(a) when testing, the top of test platform is risen to after required height by gas spring, locking gas spring, so that
Test platform is with the horizontal certain angle.
(b) determined with angel measuring instrument and record test platform and horizontal plane angulation.
(c) ultrasonic distance measuring apparatus is fixed on wheel-chair to be measured.
(d) wheel-chair is placed on test platform top, wheel-chair will start to glide.
(e) when wheel-chair reaches certain speed, the brake for opening wheel-chair opens ultrasonic distance measuring apparatus simultaneously.
(f) in the presence of brake, wheel-chair will taper off motion.Ultrasonic distance measuring apparatus can record wheel-chair automatically certainly
Braking starts to it to stop travelled distance completely.
(g) distance value measured by the angle value and ultrasonic distance measuring apparatus measured by angel measuring instrument is inserted into corresponding report
In, and the performance of wheel-chair service brake is evaluated according to concerned countries standard.
In order to which the service brake performance to wheel-chair is detected, China has formulated the standard of correlation.According to " GB/T
