Equally, just reached impulsive force during load top board to reduce vehicle, the both sides edge of load top board width can be formed with
Inclined-plane or cambered surface, thus smoothly transit with ground.When vehicle crosses, load top board is subject to compression spring after vehicle weight effect, bullet
Spring produces deformation, and triggering briquetting declines with load top board, and when such as vehicular load is without departing from assumed load, triggering briquetting will not contact
Piezoelectric transducer, warning system will not be reported to the police, and represents the load that this vehicle is without departing from highway, bridge；As vehicular load surpasses
When going out assumed load, triggering briquetting can contact the induction rod of piezoelectric transducer after declining, and piezoelectric transducer produces signal output, report
Alarm system sends alarm, represents that this vehicle exceeds highway, the load of bridge.
Finally it should be noted that listed above be only the present invention specific embodiment.It is clear that the invention is not restricted to
Above example, can also have many variations.For example, the guide frame in the present invention can also in the form of guide rail slide block,
Or the form of optical axis slide block, etc.；Described piezoelectric transducer can also be substituted for the sensor element of other forms, such as position
Displacement sensor, range sensor, fiber-optic grating sensor, etc.；The top surface of load top board can arrange protective layer, etc..This
All deformation that the those of ordinary skill in field can directly derive from present disclosure or associate, are all considered as
Protection scope of the present invention.
