As shown in fig. 1, as a preferred embodiment of the present application, the electromagnetic assembly 130 may include a first magnetic member (not shown) and a second magnetic member (not shown), the first magnetic member is located inside the supporting plate 120, the second magnetic member is disposed at least on one side of the supporting plate 120, and the first magnetic member and the second magnetic member are capable of moving relative to each other to generate an electromagnetic force for the deceleration strip.

Further, the second magnetic member may be connected to an inner sidewall of the box 200 or the supporting frame 210, so that when the supporting plate 120 drives the first magnetic member to move up and down, the second magnetic member is in a fixed state, so as to enable the first magnetic member and the second magnetic member to move relatively.

It should be noted that the first magnetic member and the second magnetic member may also be disposed at positions where the second magnetic member is located inside the supporting plate 120, and the first magnetic member is disposed at least on one side of the supporting plate 120.

Wherein, one of the first magnetic piece and the second magnetic piece is an electromagnetic coil, and the other of the first magnetic piece and the second magnetic piece is a permanent magnet. Further, the electromagnetic assembly 130 further includes a housing having a receiving cavity and a power source disposed in the receiving cavity, the second magnetic member is disposed in the receiving cavity, and a water guide hole for guiding water inflow is disposed on a surface of the housing.

It can be understood that, during the process of a vehicle passing through a speed bump, the support plate 120 is lowered due to the pressure of the wheel, the electromagnetic coil cuts the magnetic induction lines of the permanent magnet and generates induced current, and the induced current is transmitted to the power supply, which is connected with the permanent magnet, so as to strengthen the magnetic field generated by the permanent magnet; in addition, in the process of descending the support plate 120, the magnetic field gives electromagnetic force in the opposite moving direction to the support plate 120 to hinder the descending trend of the support plate 120, so that the switching of the base body 100 from the inclined state to the horizontal state can be delayed, and further, the vehicle can more smoothly pass through the deceleration strip, and a driver and passengers feel comfortable. Further, when a vehicle runs through the deceleration strip, the supporting plate 120 tends to move upwards due to the lifting damper 110 and the elastic member 140, and the electric energy stored in the permanent magnet during the descending process of the supporting plate 120 counteracts the magnetic force generated by the magnetic field and generates an upward force to the supporting plate 120 in the same direction as the moving direction, so that the speed of the deceleration strip returning to the horizontal state can be further increased.

As shown in fig. 1 and 6, as a preferred embodiment of the present invention, the lifting damping member 110 may include a sleeve 111 and a lifting rod 112 slidably engaged with the sleeve 111, a top end of the lifting rod 112 is connected to a bottom end of the supporting plate 120, and the elastic member 140 is sleeved on the lifting rod 112, wherein the elastic member 140 may be a compression spring and respectively abuts against a top end of the sleeve 111 and a bottom end of the supporting plate 120.

Specifically, when a vehicle passes through the speed bump, the base body 100 is in an inclined state, and a gap is formed between the swash plate 160 and the top plate 150. When a vehicle contacts the swash plate 160 first, the swash plate 160 receives pressure applied by the vehicle and rotates downward to drive the top plate 150 to move downward, in this process, the swash plate 160 not only rotates relative to the support frame 210, but also the protrusion 1611 of the swash plate 160 moves along the guide hole 1511, and the gap is gradually reduced in the process that the top plate 150 continuously descends. Meanwhile, the top plate 150 drives the support plate 120 to move downward, so that the base 100 is changed from an inclined state to a horizontal state, and the lifting damping member 110, the elastic member 140 and the electromagnetic assembly 130 simultaneously generate damping force, elastic force and electromagnetic force, so as to delay the tendency of the inclined state to the horizontal state, thereby achieving a deceleration effect, reducing the vibration of the vehicle, and after the vehicle passes through the deceleration strip, the support plate 120 moves upward under the reaction of the elastic force and the damping force, so as to drive the base 100 to return to the inclined state.

As an optional embodiment of the present application, the surface of the substrate 100 is coated with an elastic buffer layer (not shown in the figure), and the elastic buffer layer may be made of flexible materials such as rubber, resin, and the like, so that the cost is low, the comfort level of the vehicle when the vehicle runs over the speed bump can be improved, the substrate 100 is protected to the greatest extent, and the service life of the speed bump is prolonged.

Wherein, the surface of elastic buffer layer can match colors for yellow and black, can play the warning effect to the driver in the vision, makes the driver manual deceleration when not having reached the deceleration strip yet, can promote the speed reduction effect to prevent to the at utmost that the driver from taking place the condition of traffic accident because of the speed is too fast.

As a specific embodiment of the application, a sponge layer and a nylon layer can be arranged inside the elastic buffer layer, and the sponge layer can play a role in absorbing noise, so that noise generated by the deceleration strip is further reduced; the nylon layer can be used for blocking moisture on the surface of the speed reducing belt, so that the moisture is prevented from entering the box body 200 through the gap on the base body 100 to the greatest extent, and the electromagnetic assembly 130 and the lifting damping piece 110 are protected.

Optionally, when the deceleration strip is used, a plurality of deceleration strips such as a group of five or a group of eight may be sequentially arranged for use, and the specific number of deceleration strips is related to the width of a road, so that the deceleration effect can be improved while replacement and installation are facilitated.

Further, the speed change of the vehicle wheel passing through a speed bump is shown in fig. 7 through simulation of the application of the speed bump on the road. The driver is supposed to see that the warning coating of the elastic buffer layer part is not taken to reduce the vehicle speed or the speed reduction effect is not obvious at a distance, the vehicle speed is set to be 10m/s in the simulation by passing through a speed reducing belt at 40Km/h, the vehicle speed is set to be about 9.7m/s after the vehicle wheel passes through the speed reducing belt at 10m/s in the simulation, the speed is reduced to be about 0.3m/s, the speed reduction effect is 3%, the mass and inertia of the vehicle in the actual situation are larger, the pressing down on the base body 100 and the supporting plate 120 are stronger, and the acting forces of the electromagnetic assembly 130, the lifting damping member 110 and the elastic member 140 are also enhanced, so that the speed reduction effect in the actual situation is stronger than that seen from a simulation experiment, a certain proportional relation exists, the speed reduction effect in the actual situation is about 30%, and the vehicle speed can be reduced to a safer range. The rise in wheel set speed at 0.04s in the upper graph is caused by the error in the simulation, and the wheel set speed thereafter still tends to fall, so the error is negligible.

It can be seen that the deceleration strip that this application provided can obtain considerable speed reduction effect when in actual use to, because this application inner structure can be right the switching of base member 100 state delays, can make the vehicle can not produce the condition of velocity dip in the driving process to the at utmost, can promote driver's comfort level that traveles, protect the safety of traveling of vehicle.
