Specific embodiment：
Embodiment one：It is the structure diagram of the present invention referring to attached drawing 1.
For the sensing device of measuring vehicle speed, including pressure dynamic plate 1, it is characterized in that：
Pressure dynamic plate shaft 11 is set to 3 lower section of road surface, and pressure dynamic plate 1 can be rotated around pressure dynamic plate shaft 11,
Pressure dynamic plate 1 upwardly extends, and road surface 3 is stretched out in 1 upper end of pressure dynamic plate,
1 lower end of pressure dynamic plate is fixedly connected with press gear 12, and the center of circle of press gear 12 and the center of circle of pressure dynamic plate shaft 11
It overlaps,
Pressure dynamic plate 1 is additionally provided with the first withdrawing device 13 that pressure dynamic plate 1 is allowed to playback, one end setting of the first withdrawing device 13
In pressure dynamic plate 1, the other end is set to underground fixture,
It is additionally provided with the first ratchet 2 driven by press gear 12.
First withdrawing device 13 is elastic string or spring.
Various equivalent modifications should know：Pressure dynamic plate shaft 11 is parallel to road surface or is basically parallel to road surface, because
It is frequently not a stringent plane for road surface, so, " basic " said herein is the technology that various equivalent modifications know
It is required that.
Obviously：Various equivalent modifications should also be as knowing：Road surface is equipped with the opening for pressure dynamic plate rotation.
Definition：First ratchet 2：First ratchet 2 is the ratchet as common bicycle rear gear：When advancing to pedal,
The ratchet straps motor-car wheel drive cycling of bicycle rear；If negative direction rotates bicycle pedal, bicycle chain
The ring gear against rotation of trailing wheel ratchet surface is driven, bicycle rear does not obtain power.First ratchet 2 is the prior art, so, this
Invention does not have to introduce the detailed construction of the first ratchet 2.It can again for example：When first ratchet 2 rotates counterclockwise, ratchet
It is whole all to rotate, that is to say, that the ratchet can export power；When first ratchet 2 rotates clockwise, only ratchet table
The gear ring in face is rotating, and ratchet does not export power under this state.
The operation principle of embodiment one is such：Wheel rolling presses through pressure dynamic plate 1, and pressure dynamic plate 1 is around pressure dynamic plate shaft 11
Rotation, so as to which press gear 12 be made also to rotate, the rotation of press gear 12 can drive the rotation of the first ratchet 2.Because speed is not
Together, so, the angular speed that pressure dynamic plate 1 rotates is different, that is to say, that the wheel of friction speed presses through, and leads to turning for the first ratchet 2
It is fast different.In order to allow press through after pressure dynamic plate 1 can be made to playback, waiting presses next time, it is necessary to the first withdrawing device 13, can be with
Use elastic string, rubber rope, spring.Pressure dynamic plate 1 during original position is withdrawn by the first withdrawing device 13, the first ratchet 2
It is not export power, this is like the state for being bicycle chain reversing.
After this specification has been read, various equivalent modifications should know the position suitable for the installation of the first withdrawing device 13
It puts.
Various equivalent modifications have seen the application data, should know：The axis of pressure dynamic plate shaft 11 should be on road surface
Lower section and in horizontal direction.Pressure dynamic plate 1 can change width according to actual demands such as widths of roadway.
Embodiment two：It is the structure diagram of the present invention referring to attached drawing 2.
In order to advanced optimize embodiment one, the technical solution of use can be：Pressure dynamic plate 1 is in the part for stretching out road surface 3

Piece 611, anti-rotation sheet 611 are fixedly connected with upper pushing cylinder 61, the fixed no motion of locating piece 612 of the insertion of anti-rotation sheet 611.The words is
It explains in this way：Rotary cylinder 48 is rotation during rising, and rotary cylinder 48 can cause pushing cylinder 61 also to rotate, upper pushing cylinder
61 rotation can lead to pushing cylinder 61 and third ratchet 62 coordinate it is bad, so, on anti-rotation sheet 611 and the constraint of locating piece 612
The movement of pushing cylinder 61 makes pushing cylinder 61 that can only move up and down and cannot rotate.Related-art technology has seen the application data, should
Know that locating piece 612 should be set to fixture, for example be installed on the concrete block of 3 lower section of road surface.Pertinent art also should
When knowing, third ratchet 62, which needs manually to unlock, just can decline pushing cylinder 61.
In order to preferably coordinate upper pushing cylinder 61 and third ratchet 62, can be provided with to increase in upper 61 side of pushing cylinder
Drive the frictional layer 64 of 62 friction of third ratchet.Frictional layer 64 can be pasted on felt upper 61 side of pushing cylinder and be made
Into.In Fig. 6, there is gap between third ratchet 62 and frictional layer 64, that is in order to which reader is made to distinguish one from the other frictional layer 64 and third
Ratchet 62, in fact, various equivalent modifications should know third ratchet 62 and frictional layer 64 should be contact and have suitable
When pressure.
Various equivalent modifications have seen the application data, it is to be understood that rotary cylinder 48 turns in order to support upper pushing cylinder 61
The top of dynamic cylinder 48 should be provided with the design of the upper pushing cylinder 61 of support, such as：The top of rotary cylinder 48 is closed, with rotary cylinder 48
The upper pushing cylinder 61 of top surface support.
The extreme higher position risen to by upper pushing cylinder 61, it is possible to know the maximum speed of the automobile passed through in this period.

Be used to refer in example IV speed rotary cylinder 48 can after pressure wheel crosses pressure dynamic plate 1 falling head quickly, cause driver not
Easily see the problem of rotary cylinder 48 rises maximum height.
In embodiment six, this deficiency can be solved：Rotary cylinder 48 rises, and pushing cylinder 61 rises in promotion, still, on
The process that pushing cylinder 61 declines by the resistance that friction damping device 91 applies, declines slowly, then, driver is easy for seeing
The maximum position that upper pushing cylinder 61 rises.
Need to illustrate also has：1, upper pushing cylinder 61 can or can not slowly riseAnswer is：The speed that upper pushing cylinder 61 rises only by
48 rate of climb of rotary cylinder determines.Because upper pushing cylinder 61 is by thrust (rotary cylinder 48 applies), also by resistance (frictional damping
Device 91 applies), thrust specific resistance is much larger, so, the speed that upper pushing cylinder 61 rises only is determined by 48 rate of climb of rotary cylinder.

The sharp end of bull stick 71 under road surface 3 during stationary state pulling force suffered by cord 73 be F2, -1.5 times of F1=1.2 times --- ---
F2, certain F1 can also be equal to 1.3 times of F2, and F1 can also be equal to 1.4 times of F2, and F1 can also be equal to 1.35 times of F2, and F1 can also
Equal to 1.36 times F2.
Cord 73 can not ether it is solid, too it is solid do not allow it is easily broken, also can not ether it is fragile, otherwise easy spontaneous disruption.
The technical solution of optimization：The rotation axis 7 is ratchet.Various equivalent modifications it is to be understood that in the present embodiment,
Rotation axis 7 preferably plays the role of two：1, V-arrangement bull stick 71 can be rotated, 2, it, can after 71 long bar portion of V-arrangement bull stick is allowed to rise
To prevent 71 backwards rotation of V-arrangement bull stick.So it is best-of-breed technology scheme that rotation axis 7, which is ratchet,.This ratchet can allow V-arrangement to turn
Bar 71 rotates after cord 73 is broken, and may insure that V-arrangement bull stick 71 will not be gone back to again and come.
Rotation axis 7 is that ratchet is necessary technology schemeIt answers and is：It is not necessary technology scheme.As long as because selection
Suitable angle of inclination can allow V-arrangement bull stick 71 no longer to rotate, so as to puncture tire.This angle, related-art technology people
Member can determine relevant parameter by the experiment of conventional Mechanics Calculation or limited number of time.
Embodiment 11：
