Abstract
The invention provides a road speed limiting device which comprises a speed limiting device, a piezoelectric module and a road warning device, wherein the speed limiting device is arranged on road sections, such as schools or home communities, which need drivers to slow down; the piezoelectric module is arranged in the speed limiting device; and the road warning device is electrically connected with the piezoelectric module. According to the road speed limiting device, the drivers can be forced to lower the vehicle speed, and the road speed limiting device can automatically supply power to the road warning device to achieve the function of reminding the drivers so as to perform the multiple protection action on pedestrians.
Description
[technical field]
The present invention relates to a kind of road speed limit device, particularly relate to a kind of road speed limit device of strengthening warning.
[background technology]
As shown in Figure 1; Can install road speed limit device 4 mostly in highway sections such as school or home communities, cause to drive and to reduce the speed of a motor vehicle when passing through said road speed limit device 4 in order to avoid cause the automobile suspension system or chassis system damages and then reaches the probability that the reduction accident produces because road speed limit device protrudes from the road surface.
Be the pedestrian who strengthens the above-mentioned highway section of protection, the driver who reminds the above-mentioned highway section of passing through, also can add by the road mostly and remind guideboard 5 devices.Yet existing function of reminding device such as guideboard often when night or weather are not good, can't reach the prompting driver.
Therefore be the pedestrian who protects above-mentioned highway section, the driver who reminds the above-mentioned highway section of passing through, relevant apparatus has the space of further improvement really.
[summary of the invention]
Main purpose of the present invention is to provide a kind of road speed limit device, and said road speed limit device comprises:
The speed-limiting device body;
Several piezo electric module are arranged on the said speed-limiting device body; And
Several road indicating devices are positioned over the road both sides and electrically connect with piezo electric module.
For letting the foregoing of the present invention can be more obviously understandable, hereinafter is special lifts preferred embodiment, and cooperates appended graphicly, elaborates as follows:
[description of drawings]
Fig. 1 shows the sketch map of existing road speed-limiting device;
Fig. 2 shows the sketch map according to the road speed limit device of one embodiment of the invention.
[specific embodiment]
Below the explanation of each embodiment be with reference to additional graphic, can be in order to illustration the present invention in order to the specific embodiment of implementing.The direction term that the present invention mentioned, for example " on ", D score, " preceding ", " back ", " left side ", " right side ", " interior ", " outward ", " side " etc., only be direction with reference to annexed drawings.Therefore, the direction term of use is in order to explanation and understands the present invention, but not in order to restriction the present invention.
In the drawings, the unit of structural similarity is to represent with same numeral.
Please with reference to Fig. 2, Fig. 2 shows the sketch map according to the road speed limit device of one embodiment of the invention.The road speed limit device of present embodiment comprises road speed limit device 1, a plurality of piezo electric module 2, a plurality of road indicating device 3.
As shown in Figure 2, the road speed limit device 1 of present embodiment is to be assembled by a plurality of speed-limiting device bodies 11.Road speed limit device 1 by speed-limiting device body 11 protrusion road surfaces to reach the purpose that forces the driver to reduce the speed of a motor vehicle.
As shown in Figure 2, the piezo electric module 2 of present embodiment is arranged on the said speed-limiting device body 11, when the vehicle of passing by passes through piezo electric module 2, produces electric power because of piezo electric module 2 pressurizeds force its.
As shown in Figure 2; The road indicating device 3 of present embodiment is positioned over the both sides in desire caution highway section and electrically connects with piezo electric module 2; For the road indicating device 3 that improves the alarm function present embodiment is all processed by the LED lamp,, the vehicle of passing by causes in the road indicating device 3 when passing through piezo electric module 2 because of piezo electric module 2 pressurizeds force its generation electric power and then power supply.
In the present embodiment, when the vehicle of passing by passes through the 11 last times of speed-limiting device body that are equiped with piezo electric module 2,, and then can supply power to road indicating device 3 because piezo electric module 2 pressurizeds force its to produce electric power.
From the above, the road speed limit device that can generate electricity voluntarily of the present invention can force the driver to reduce the purpose of the speed of a motor vehicle by speed-limiting device body 11, can improve alarm function by road indicating device 3 again.
In sum; Though the present invention discloses as above with preferred embodiment; But above-mentioned preferred embodiment is not that those of ordinary skill in the art is not breaking away from the spirit and scope of the present invention in order to restriction the present invention; All can do various changes and retouching, so protection scope of the present invention is as the criterion with the scope that claim defines.
