Technical Field
The invention relates to a traffic zebra crossing, in particular to a pneumatic zebra crossing for blind people.
Background
In China, millions of blind people are the largest blind people in the world, and tens of millions of vision-disabled patients are also included. Although China already has the longest blind roads and the widest distribution in the world, none of the blind roads is absolutely cut off before people pass through a road, namely zebra crossings. The zebra crossing is used as a sign for pedestrians to cross streets and is a must for blind people and visual patients in some special places. But the existing zebra stripes do not play any prompting role for the blind.
In order to solve the problems, research and development focuses of domestic and foreign scientific research institutions and scientific and technological companies tend to be intelligent wearable equipment, but the equipment has no defects of high cost, poor precision, suitability for laboratory environments and the like, and is not on the market at home and late. Such as patent numbers: 201610288613.9, the perception guide shoes are provided with a plurality of blind-guiding shoes,
the scheme adopted on the road in China at present specifically comprises the steps that a voice prompt device is placed on a zebra crossing traffic light to prompt the blind when the traffic light changes, but specific prompt cannot be provided for the blind on the zebra crossing. Such as patent numbers: 201520496580.8 integrated intelligent zebra crossing pedestrian signal light.
Another solution is to lay a blind road directly on the zebra crossing, which is commonly used in japan. In China, a precedent is given, the first blind zebra crossing in China is laid on a special road section before the blind deaf-mute school in 25 Risu city in 4.4.2010, and although the blind zebra crossing is good for the tide at first, the blind zebra crossing not only influences the normal running of an automobile, but also is easy to make noise. Eventually only half a month or so is there and the problem has not been solved until now.

The specific implementation mode is as follows:
in order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:
firstly, fig. 1-4 are schematic parts of the pneumatic lifting zebra crossing for the blind, and a movable part 1 is in an inverted T shape and can be made of 45-grade steel or stainless steel. Be equipped with the buffering part on the movable part, the buffering part is including buffering speed reduction pad 2, and buffering cushion 2 includes upside buffering cushion 2a and downside buffering cushion 2b, upside buffering cushion 2a and downside buffering cushion 2b set up respectively on the upper and lower both sides of movable part bottom for at the buffering of lift in-process, avoid noise and wearing and tearing, specific available rubber shock pad. The downside buffering shock pad 2b below is opened there is the shrinkage pool, and the shrinkage pool can be circular hole for place shrink spring 3, and the recess bottom of shrink spring 3 downside and casing is fixed, is used for the normal decline of supplementary movable part. The shape of the groove is matched with that of the movable part, the inverted T-shaped groove in the shell is slightly larger than the movable part, namely, the movable part can be completely placed in the groove of the shell and can move up and down without being influenced. And an air bag 5 for starting the transmission part is arranged between the lower end of the movable part and the shell.
Fig. 4 shows only one section 4 of the housing, in which the inverted T-shaped groove is formed, and in practice, the housing is made of a relatively solid material, such as 45 steel, and a plurality of grooves are formed therein.
Fig. 5 is a diagram of a pneumatic transmission component of the pneumatic lifting zebra crossing for the blind, which comprises an air bag 5, an air hose 6, an air valve 7, an air pump 8, a lead 9 and a main control module 10. The air bag 5 is arranged in the groove of the shell and below the movable part, and the air bag 5 is connected with an air valve 7 through an air hose 6. The main control module 10 is directly connected with the air valve 7 and the air pump 8 through a lead 9 to control the air supply and exhaust of the air bag 5. The general master control module can be realized by a single chip microcomputer or STM32, and the time of inflation and deflation is controlled by a timer in the master control module. When the airbag is needed to be inflated, the main control module opens the air valve and controls the air pump to inflate, the air pump is stopped and the air valve is closed to avoid air leakage of the airbag when the preset inflation time is reached. When the air bag needs to be deflated, the main control module controls the air pump to be started and controls the air pump to evacuate, the air pump is stopped and the air valve is closed when the preset time for evacuating is reached. The air pump is a bidirectional air pump, and can realize air exhaust and air supply integration. The air bag can also be additionally provided with an exhaust valve, the exhaust valve is controlled by the main control module, when the air bag needs to be inflated, the main control module opens the air valve 7 and controls the air pump 8 to inflate, and when the preset inflation time is reached, the air pump 8 is stopped and the air valve 7 is closed to avoid air leakage of the air bag 5; when the air bag 5 needs to be deflated, the main control module 1 controls the exhaust valve to exhaust air, and when the preset air pressure is reached, the exhaust valve is closed. The traffic signal lamp is in communication connection with the traffic signal controller through the main control module to acquire information and timely control the pneumatic lifting of the zebra crossing of the blind person so as to keep consistent with the change of the signal lamp.
The above is the core content of the present invention. Fill gassing and spring tensile cooperation through the gasbag under, the movable part can rise when the green light of people is current in the casing recess, and the movable part is higher than housing face 5mm height this moment, and the blind person moves ahead with the same height guide of normal blind road, descends in the red light, and movable part upper surface and housing face flush this moment, and the vehicle is normally current not hindered, and can not send the noise. The problem that the blind person crosses the road is solved, and the potential social contradiction is avoided.
The reason why the air bag is adopted as the transmission device is that the phenomenon that the vehicle runs in violation of traffic or occupies the zebra crossing when the pedestrian passes is common at home and abroad, and the common lifting mode is easy to damage when the vehicle is used in the rising state in the zebra crossing of the blind person, so that the service life of the vehicle is greatly shortened. The invention utilizes the air bag well to utilize the good compressibility of air, when the automobile runs in violation of traffic or is occupied in a lifting state, the wheel can be pressed up because the height of the movable part is only 5mm higher than the ground, the air in the air bag can be easily compressed to enable the movable part to descend until the movable part completely descends, the upper surface is level with the surface of the shell, and then most pressure of the pressure can be transferred to the shell, thereby greatly reducing the probability of damage of the movable part. Therefore, the pneumatic lifting zebra crossing for the blind has excellent self-protection capability in practical application.
The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner. Those skilled in the art can make numerous possible variations and modifications to the present teachings, or modify equivalent embodiments to equivalent variations, without departing from the scope of the present teachings, using the methods and techniques disclosed above. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
