Problems solved by technology

[0002] At present, the car has become a relatively popular means of transportation. During driving, the speed limit is directly related to public safety; while the driver will ignore the situation in front of the car when checking the speedometer when driving, which is likely to cause danger; On the other hand, more roads do not have speed limit signs. Even if the speed limit signs usually only appear at intersections, they are easily ignored. Therefore, in many cases, drivers do not know the speed limit situation of the current road at all, which makes The driver has trouble controlling the speed of the car

Abstract

The invention discloses a highway safety pre-warning device. The highway safety pre-warning device comprises a pavement groove and a side cavity which are formed in the ground; the pavement groove andthe side cavity are correspondingly formed in the two sides of a road guardrail; the pavement groove and the side cavity are mutually and rotationally connected with a rolling shaft; the parts, positioned in the pavement groove and the side cavity, of the rolling shaft are fixedly connected with a rolling wheel and a driving gear; a driven gear is engaged with the driving gear; a centrifugal plate is fixed on the lower end surface of the driven gear; and the centrifugal plate is rotationally connected to the lower wall of the side cavity. The highway safety pre-warning device has the advantages that the rolling wheel drives the centrifugal plate to rotate at a low speed when the speed of a vehicle running on a road is lower; at the moment, the centrifugal force borne on an annular sealingpiece cannot drive the annular sealing piece to move to the edge of the centrifugal plate, and therefore, a vertical rod is positioned in a low position without being in contact with a red light; andat the moment, as only a green light is in a turn-on state in a display cavity, a sign that the vehicle speed is normal and the vehicle can continue to run is given for a vehicle driver.

Description

technical field [0001] The invention relates to the technical field of highway speed limit, in particular to a highway safety early warning device. Background technique [0002] At present, the car has become a relatively popular means of transportation. During driving, the speed limit is directly related to public safety; while the driver is driving, he will ignore the situation in front of the car when checking the speedometer, which is likely to cause danger; On the other hand, more roads do not have speed limit signs. Even if the speed limit signs usually only appear at intersections, they are easily ignored. Therefore, in many cases, drivers do not know the speed limit of the current road at all, which makes It is difficult for the driver to control the speed of the vehicle. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a road safety early warning device. [0004] In order to achieve th...
