Description

Technical Field

[0001] The invention relates to the technical field of traffic safety facilities, and in particular to a liftable warning device for pedestrians crossing zebra crossings. Background Art

[0002] In dim environments or at intersections without traffic lights, zebra crossings cannot guarantee the absolute safety of pedestrians crossing the street. Especially on the main traffic arteries in the city, the traffic volume is high, and in the case of curves, the side vision of some running vehicles is easily blocked by the green belts on both sides of the road. When a vehicle is driving on a road section with a higher design speed, if the driver does not slow down in advance, and brakes suddenly to give way to pedestrians within a range close to the zebra crossing, or encounters pedestrians who do not follow the pedestrian crossing signal and suddenly rush out from the zebra crossing, etc., it will also cause the driver to have no time to react and brake suddenly, resulting in traffic accidents such as a chain collision of subsequent vehicles. The above phenomenon is not uncommon. Although most cities in China have proposed traffic management measures for road drivers to slow down and give way to pedestrians at zebra crossings, in implementation, due to differences between individual drivers and pedestrians, the above phenomenon cannot be fundamentally eliminated. Summary of the invention

[0003] In response to the technical problems raised above, a liftable warning device for pedestrians crossing zebra crossings is provided. The warning device of the present invention is installed on both sides of the zebra crossing. In a dim light environment, the device is powered by a photoresistor. When a pedestrian wants to cross the zebra crossing, the infrared sensor detects the pedestrian and starts the steering gear, so that the solar warning device rises from the ground and lights up the LED lamp, which serves to warn vehicles on both sides of the zebra crossing to slow down.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation.
