All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic diagram of a road surface pressure-sensitive component according to an embodiment of the present invention is shown. The embodiment provides a road surface pressure sensitive component, including: the pressure-sensitive sensing unit 10, the pavement elastic cover plate 20 positioned on the pressure-sensitive sensing unit 10, and the strain detection unit 30 electrically connected with the pressure-sensitive sensing unit 10; the pressure-sensitive sensing unit 10 is used for acquiring deformation information of the elastic road cover plate 20 and generating a strain signal according to the deformation information, and the strain detection unit 30 is used for performing road treading response control when it is determined that treading is performed according to the strain signal.
In this embodiment, the pavement pressure-sensitive assembly includes a pressure-sensitive sensing unit 10 and a pavement elastic cover 20 on the pressure-sensitive sensing unit 10. The above of the pressure-sensitive sensing unit 10 specifically refers to a side of the pressure-sensitive sensing unit 10 close to the road surface, and the pavement elastic cover 20 is located on the pressure-sensitive sensing unit 10 specifically refers to the pavement elastic cover 20 is disposed right above the pressure-sensitive sensing unit 10. It can be understood that the pavement elastic cover plate 20 completely covers or at least partially covers the pressure-sensitive sensing unit 10, so that the pressure-sensitive sensing unit 10 can collect the deformation information of the pavement elastic cover plate 20. The elastic cover plate 20 is used as a part of the road surface, can be flush with the road surface, and can also be set to have a smaller difference with the road surface, so that pedestrians can accurately distinguish the elastic cover plate of the road surface and then tread on the elastic cover plate. When the pedestrian steps on the road surface elastic cover plate 20, the road surface elastic cover plate 20 is pressed downward.
It can be understood that the pavement elastic cover plate 20 has elasticity and sinks under pressure to allow the pressure sensitive sensing unit 10 to sense a deformation signal. The material of the elastic road cover plate 20 can be selected from any elastic material which can be used for pedestrians to tread on the road surface, and the elastic road cover plate has the advantages of being wear-resistant, strong in pressure bearing and the like. The pavement pressure-sensitive component can be arranged in the pavement, response control is carried out according to treading of pedestrians, the landscape pavement can be enriched, the pressure-sensitive sounding or luminous artistic pavement is formed, and the pavement pressure-sensitive component is particularly suitable for landscape pedestrian footpaths.
In this embodiment, the pressure-sensitive sensing unit 10 is disposed under the elastic road cover 20 and will deform under stress. The optional pressure sensitive sensing unit 10 comprises a strain gauge, and when a pedestrian steps on the road surface elastic cover plate 20, the road surface elastic cover plate 20 is pressed downwards, so that the length of the strain gauge in the pressure sensitive sensing unit 10 is changed. It should be noted that, when the elastic road cover 20 is not stepped on, the length of the strain gauge in the pressure-sensitive sensing unit 10 is not changed, but the pressure-sensitive sensing unit 10 still generates a strain signal according to the length of the strain gauge, and the strain gauge length information carried in the strain information indicates that the strain gauge is not deformed. When the road surface elastic cover plate 20 is trampled, the length of the strain gauge in the pressure-sensitive sensing unit 10 changes, the pressure-sensitive sensing unit 10 generates a strain signal according to the length of the strain gauge, and the strain gauge length information carried in the strain information represents the deformation and deformation of the strain gauge.
Specifically, when the pedestrian steps on the elastic road surface cover plate 20, the pedestrian steps on the pressure to cause the elastic road surface cover plate 20 to extrude downwards, and when the elastic road surface cover plate 20 sinks under the pressure bearing, a strain concentration is caused below the elastic road surface cover plate 20, so that the shape of the pressure-sensitive sensing unit 10 arranged below the elastic road surface cover plate 20 is changed, that is, the deformation of the pressure-sensitive sensing unit 10 is caused. The pressure-sensitive sensing unit 10 can collect the deformation information of the elastic cover plate 20 and generate a strain signal according to the deformation information. It can be understood that, when the pedestrian steps on the elastic road cover plate 20, the elastic road cover plate 20 bears pressure and sinks, the deformation information specifically refers to the stress related information of the elastic road cover plate 20, and the strain information specifically refers to the deformation generated by the pressure-sensitive sensing unit 10 according to the stress and other related information of the elastic road cover plate 20. Obviously, the greater the pressure of the pedestrian stepping on the road surface elastic cover plate 10, the greater the deformation of the pressure-sensitive sensing unit 10.
In the present embodiment, the strain detection unit 30 is electrically connected to the pressure sensitive sensing unit 10. It is understood that the strain detection unit 30 may be disposed adjacent to the pressure sensitive sensing unit 10 and particularly below the road surface elastic cover plate 20 to avoid damage to the strain detection unit 30 due to the pedestrian's pedaling pressure. The strain detection unit 30 can also be electrically connected with the pressure-sensitive sensing unit 10 and far away from the underside of the pavement elastic cover plate 20. The strain detection means 30 is for performing road surface treading response control when it is determined that treading is present, based on the strain signal. The strain detection unit 30 may be configured to determine whether the pressure sensitive sensing unit 10 is deformed according to the strain signal, determine that the road surface elastic cover plate 20 is trodden if the pressure sensitive sensing unit 10 is determined to be deformed, and determine that the road surface elastic cover plate 20 is not trodden if the pressure sensitive sensing unit 10 is determined to be not deformed.
Specifically, the pressure-sensitive sensing unit 10 includes a strain gauge, and the strain gauge has an original length value when being undeformed. The strain detection unit 30 may be configured to determine length information of a strain gauge in the pressure-sensitive sensing unit 10 according to the strain signal, and compare the length information with an original length value of the strain gauge, obviously, if the strain detection unit 30 detects that the length information of the strain gauge is different from the original length value, it is determined that the pressure-sensitive sensing unit 10 is deformed, and if the strain detection unit 30 detects that the length information of the strain gauge is the same as the original length value, it is determined that the pressure-sensitive sensing unit 10 is not deformed.
In the present embodiment, the strain detection unit 30 is configured to perform road surface stepping response control when it is determined that stepping is performed based on the strain signal. The road surface stepping response control may be selected as a sound control or a display control. If the strain detection unit 30 determines that there is a step on, it transmits a step signal to the control module to make the control module perform corresponding road surface step response control, for example, the control module may trigger the display module to display according to the step signal, and/or the control module may trigger the sound generation module to perform sound response according to the step signal. The specific pedaling response control process and pedaling response mode are not described in detail herein.
In this embodiment, the pavement pressure-sensitive assembly includes a pressure-sensitive sensing unit, a pavement elastic cover plate on the pressure-sensitive sensing unit, and a strain detection unit electrically connected to the pressure-sensitive sensing unit; the pressure-sensitive sensing unit is used for acquiring deformation information of the pavement elastic cover plate and generating a strain signal according to the deformation information, and the strain detection unit is used for carrying out pavement treading response control when treading is judged according to the strain signal.

In this embodiment, the elastic road cover plate 20 includes a first cover plate 21 and a strain concentration plate 22 attached to the first cover plate 21, and it can be understood that the first cover plate 21 and the strain concentration plate 22 are both elastic plates and can deform under pressure. When the cover plate area corresponding to the strain concentration plate 22 is stepped, a strain concentration is caused, and the length of the strain gauge in the pressure sensitive sensing unit 10 can be effectively changed, so that the pressure sensitive sensing unit 10 obtains deformation information. The strain concentration plate 22 protruding below the first cover plate 21 has an advantage that when the cover plate area corresponding to the strain concentration plate 22 is stepped, a strain concentration is caused, so that the pressure sensitive sensing unit 10 can sense a larger sinking signal, and the strain gauge changes the length, thereby improving the sensing sensitivity and accuracy of the pressure sensitive sensing unit 10. Preferably, the orthographic projection of the strain concentrating plate 22 on the plane of the first cover plate 21 covers the pressure sensitive sensing unit 10.
In addition, when the pedestrian steps on the first cover plate 21, only when the pedestrian steps on the area of the first cover plate 21 covered by the strain concentrating plate 22, the pressure-sensitive sensing unit 10 can be deformed, so that the area of the first cover plate 21 covered by the strain concentrating plate 22 of the elastic road cover plate 20 can be made into a surface design different from the surface design of the other areas of the first cover plate 21, and the interest of stepping can be increased.

The first elastic layer 41 can transmit a pressure-sensitive sensing unit 10 with a deformation signal of the pavement elastic cover plate 20 bearing pressure sinking, and can also protect the pressure-sensitive sensing unit 10, so that the pressure-sensitive sensing unit 10 is prevented from being damaged due to the direct influence of the pavement elastic cover plate 20 bearing pressure sinking, and the service life of the pressure-sensitive sensing unit 10 is prolonged on the basis of not influencing pressure-sensitive sensing.
