Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of speed bump, and particularly relates to a speed bump with automatic height adjustment. BACKGROUND

[0002] The speed bump is a kind of highway infrastructure which can make drivers brake voluntarily by affecting the psychology of the drivers. The speed bump is essentially a warning device which reminds drivers that there may be other road users in front of the speed bump. When the drivers observe the speed bump in front, they will instinctively step on the brake to force the vehicle to slow down to pass the speed bump smoothly, otherwise, the impact of the speed bump and the wheels of the vehicle will feed back to the driver and passengers a large vertical impact force, which will cause psychological stimulation to the driver and passengers.

[0003] In the prior art, the general highway speed bump has a poor deterrent effect on the drivers of heavy load vehicles, mainly because the heavy load vehicles have large mass and large wheel diameters, and the impact feedback when rolling over the speed bump is easy to adapt to the drivers. In addition, due to the repeated rolling of the passing vehicles, the service life of the highway speed bump is short, which will also weaken the warning effect of the highway speed bump to a certain extent. SUMMARY

[0004] The application provides a speed bump with automatic height adjustment, which can improve the speed reduction effect and warning effect of the speed bump, and prolong the service life of the speed bump.

[0005] The technical scheme adopted by the application is as follows:

[0006] The speed bump with automatic height adjustment comprises a road surface and a roadbed below the road surface, the roadbed is provided with a first groove and a second groove arranged in sequence along the forward direction of the road, and the first groove and the second groove are connected in communication through a passage; the first groove and the second groove are both extended upward to the road surface and form a first slot and a second slot along the lateral direction of the road on the road surface respectively, and the width of the first slot in the longitudinal direction of the road is greater than that of the second slot.

[0007] The first slot is provided with a first speed bump matched with the width of the first slot, a first horizontal plate below the first speed bump can seal the first groove, the first horizontal plate can move upward under the action of liquid force, and a first vertical plate is arranged between the first horizontal plate and the first speed bump; the second slot is provided with a second speed bump matched with the width of the second slot, a second horizontal plate below the second speed bump can seal the second groove, the second horizontal plate can move upward under the action of liquid force, and a second vertical plate is arranged between the second horizontal plate and the second speed bump.

[0008] The first horizontal plate, the second horizontal plate and the channel form a first sealed cavity capable of containing liquid, the first sealed cavity is filled with liquid, the first horizontal plate can press into the liquid in the second groove when the first deceleration belt is pressed, so that the second deceleration belt moves upward under the driving of the second horizontal plate, and the second horizontal plate can press into the liquid in the first groove when the second deceleration belt is pressed, so that the first deceleration belt moves upward under the driving of the first horizontal plate.

[0009] Further, the first deceleration belt has a first position protruding from the road surface under the action of gravity, and a second position flush with the road surface under the action of pressure; when the first deceleration belt is in the first position, the second deceleration belt has a third position higher than the first position; when the first deceleration belt is in the second position, the second deceleration belt has a fourth position higher than the third position.

[0010] Further, a third horizontal plate is arranged between the second deceleration belt and the second horizontal plate, and a second sealed cavity separated from the first sealed cavity is formed between the third horizontal plate and the second horizontal plate, and the second sealed cavity is filled with liquid.

[0011] Further, the third horizontal plate is fixed at both ends of the second groove, and the middle of the third horizontal plate is slidably connected to the second vertical plate.

[0012] Further, the roadbed on one side of the second sealed cavity is provided with an upwardly inclined liquid storage chamber, when the second horizontal plate moves upward, the liquid in the second sealed cavity flows into the liquid storage chamber; when the second horizontal plate moves downward, the liquid in the liquid storage chamber flows into the second sealed cavity.

[0013] Further, when the first deceleration belt is in the second position, the position of the second horizontal plate is lower than the lower end of the liquid storage chamber.

[0014] Further, an inclined section for increasing the diameter of the channel is arranged at the connection between the first groove and the channel.

[0015] Further, the first vertical plate is provided with a reinforcing vertical plate on both sides of the first deceleration belt.

[0016] The beneficial effects of the present application are:

[0017] 1. The application can achieve different deceleration effects according to the vehicle weight. The down pressure generated by large heavy trucks when rolling on the first deceleration strip will be transmitted to the first horizontal plate more quickly, and the first horizontal plate moves downward to press the liquid in the first sealed cavity relatively quickly, so that the second horizontal plate is quickly lifted to realize the quick lifting of the second deceleration strip. When small vehicles face a slightly higher ground obstacle, they will also avoid bottoming out by braking, and the lifting height of the first deceleration strip can be changed to change the braking speed of small vehicles. In order to match the lifting / descending speed between the first deceleration strip and the second deceleration strip, the application increases the contact area between the first deceleration strip to be rolled first and the tire by setting different deceleration strip mounting openings (first and second slots), which helps the front wheels to pass smoothly and plays a preliminary warning role. On the other hand, the larger contact area can improve the rolling efficiency, that is, the first horizontal plate moves a short distance downward to move the second horizontal plate a long distance upward. The greater the load of the vehicle, the higher the speed and height of the second deceleration strip are lifted, and the more obvious the warning effect on the driver is.

[0018] 2. The application can achieve different warning effects according to the vehicle speed. In the application, the first deceleration strip rolled first and the second deceleration strip rolled subsequently have a linkage effect, and the second deceleration strip is lifted when the first deceleration strip is rolled, and the first deceleration strip is lifted again when the vehicle passes through the second deceleration strip. When the vehicle reaches the first deceleration strip without braking to the appropriate speed, the front wheels of the vehicle are lifted to a small height or have a lifting trend, and the impact feedback on the driver is relatively weak, but when the front wheels are then impacted by the second deceleration strip for the second time, the impact feedback generated is greater than that when passing through the second deceleration strip at the same speed, which can form a more obvious psychological stimulation on the driver, so that the driver will actively brake to make the rear wheels pass through the deceleration strip smoothly, otherwise the large vibration of the rear wheels may cause a large noise or affect the stability of the goods.

[0019] 3. Compared with the traditional deceleration strip with constant height, the application can reduce the working frequency and prolong the service life of the deceleration strip by adjusting the height of the deceleration strip according to the vehicle speed and weight.

[0020] 4. As a preferred embodiment of the application, the lifting time of the second deceleration strip can be optimized by setting the structure of the liquid storage chamber to adapt to the scenario of continuous vehicle passing. The essence of constructing the liquid storage chamber is to change the lifting process of the second horizontal plate. When the deceleration strip is not rolled, the first deceleration strip and the second deceleration strip are stable at the set position, and the pressure of the liquid in the first slot on the liquid in the second sealed cavity includes the gravity of the liquid in the second sealed cavity. When the second horizontal plate is lifted, the liquid in the second sealed cavity flows into the liquid storage chamber, and the higher the second horizontal plate is lifted, the more liquid flows into the liquid storage chamber, and the second deceleration strip can be lifted more quickly.

DETAILED DESCRIPTION

[0029] An automatic height-adjustable speed bump, comprising a road surface A and a roadbed B below the road surface A, the roadbed B is provided with a first groove 1-1 and a second groove 2-1 arranged in sequence along the forward direction of the road, and the first groove 1-1 and the second groove 2-1 are connected in communication through a passage 3; the first groove 1-1 and the second groove 2-1 both extend upward to the road surface A and form a first slot 1-2 and a second slot 2-2 along the lateral direction of the road on the road surface A respectively, the width of the first slot 1-2 in the longitudinal section of the road is greater than that of the second slot 2-2.

[0030] The first slot 1-2 is provided with a first deceleration band 1 that matches its width. Below the first deceleration band 1 is a first horizontal plate 1-3 that can seal the first slot 1-1. The first horizontal plate 1-3 can move upward under hydraulic force. A first vertical plate 1-4 is provided between the first horizontal plate 1-3 and the first deceleration band 1. The second slot 2-2 is provided with a second deceleration band 2 that matches its width. Below the second deceleration band 2 is a second horizontal plate 2-3 that can seal the second slot 2-1. The second horizontal plate 2-3 can move upward under hydraulic force. A second vertical plate 2-4 is provided between the second horizontal plate 2-3 and the second deceleration band 2.

[0031] The first horizontal plate 1-3, the second horizontal plate 2-3, and the channel 3 form a first sealed cavity 4 that can contain liquid. The first horizontal plate 1-3 can press liquid into the second tank 2-1 when the first speed bump 1 is pressed, so that the second speed bump 2 moves upward under the action of the second horizontal plate 2-3. The second horizontal plate 2-3 can also press liquid into the first tank 1-1 when the second speed bump 2 is pressed, so that the first speed bump 1 moves upward under the action of the first horizontal plate 1-3.

[0032] The warning effect of speed bumps decreases over time due to repeated vehicle traffic. On one hand, the pressure and deformation of speed bumps over extended periods reduces their height, potentially causing vehicles to drive across them without slowing down, prioritizing smooth driving. On the other hand, traditional speed bumps have a less deterrent effect on heavy vehicles than on smaller vehicles, while large vehicles have larger blind spots and longer braking distances, making their failure to slow down when crossing speed bumps a greater safety hazard. (See attached document.) Figure 1 and attached Figure 2 As shown, Figure 1 The first speed bump 1 protrudes from road surface A and is located at the first position. The way it protrudes from road surface A and its relatively large width have different effects on different vehicle types: small vehicles will actively brake to prevent bottoming out when passing over it, while for large vehicles it serves as a warning, reminding them to slow down in advance to avoid a large impact feedback from the second speed bump 2. When a vehicle has not driven over it, the second speed bump 2 is located at the third position, and the height of the third position is higher than the first position.

[0033] As attached Figure 2 As shown, when a heavy truck runs over it, the maximum drop position of the first speed bump 1 is flush with the road surface A; this position is the second position. The height of the second position can be achieved by designing according to the dimensions of the first tank 1-1 and the liquid inside. When the first speed bump 1 is in the first position, the second speed bump 2 reaches its highest value (fourth position), which has the strongest deterrent effect on vehicles.

[0034] As a preferred embodiment of the present application, the movement of the first cross plate 1-3 and the second cross plate 2-3 in the first groove body 1-1 and the second groove body 2-1 respectively is achieved by the related art of existing hydraulic equipment. The gap between the first deceleration strip 1 and the second deceleration strip 2 and the first slot 1-2 and the second slot 2-2 is small, and a related protection structure such as a baffle can be arranged inside the first slot 1-2 and the second slot 2-2 to avoid small gravel from falling in, or the slot edge and the deceleration strip edge can be connected in sliding connection.

[0035] As a preferred embodiment of the present application, as shown in the accompanying drawings Figure 3 and the accompanying drawings Figure 4 , the third cross plate 2-5 is arranged between the second deceleration strip 2 and the second cross plate 2-3, and the second cross plate 2-3 and the third cross plate 2-5 form the second sealed cavity 5 which is separated from the first sealed cavity 4, and the second sealed cavity 5 is filled with liquid. The two ends of the third cross plate 2-5 are fixed to the two ends of the second groove body 2-1, and the middle of the third cross plate 2-5 is in sliding connection with the second vertical plate 2-4. The roadbed B on one side of the second sealed cavity 5 is provided with a liquid storage chamber 6 which is inclined upward, and when the second cross plate 2-3 moves upward, the liquid in the second sealed cavity 5 flows into the liquid storage chamber 6; when the second cross plate 2-3 moves downward, the liquid in the liquid storage chamber 6 flows into the second sealed cavity 5.

[0036] In a specific embodiment of the above-mentioned embodiment, the cross-sectional shape of the liquid storage chamber 6 is a zigzag shape, and the inclination near the outlet is greater, which is more conducive to the flow of liquid. The volume of the liquid storage chamber 6 should be determined according to the specific moving height of the second deceleration strip 2. Because by controlling the volume of the liquid storage chamber 6, the distance of the upward movement of the second cross plate 2-3 can be controlled, and in turn the second deceleration strip 2 can be limited. The present embodiment provides a layered hydraulic idea, and by arranging the structure of the liquid storage chamber 6, the lifting time of the second deceleration strip 2 can be optimized to adapt to the scene of continuous vehicles passing through. The essence of constructing the liquid storage chamber 6 is to accelerate the lifting process of the second cross plate 2-3. When the deceleration strip is not subjected to rolling, the first deceleration strip 1 and the second deceleration strip 2 are stable at the set position, and the pressure of the liquid in the first groove body 1-1 exerted by the second deceleration strip 2 includes the gravity of the liquid in the second sealed cavity 5. When the second cross plate 2-3 is lifted, the liquid in the second sealed cavity 5 is pushed to flow into the liquid storage chamber 6, and the higher the second cross plate 2-3 is lifted, the more liquid flows into the liquid storage chamber 6, and in turn the gravity of the liquid that the second cross plate 2-3 overcomes is smaller. Considering the length of the liquid storage chamber 6, the reduced gravity cannot be ignored, so the second deceleration strip 2 can be lifted more quickly. In specific implementation, the total amount of liquid in the first sealed cavity 4 and the second sealed cavity 5 can be controlled to be unchanged, the size of the second vertical plate 2-4 is increased, and the weight of the liquid in the second sealed cavity 5 is greater than the weight increase caused by the increase in size, so as to achieve the effect of rapid lifting.

[0037] In one preferred embodiment of the above-mentioned embodiments, when the first deceleration strip 1 is in the second position, the second horizontal plate 2-3 is positioned lower than the lower end of the liquid storage chamber 6. This design aims to avoid the liquid in the liquid storage chamber 6 flowing into the first sealing chamber 4, and to ensure the working effect of the second deceleration strip 2.

[0038] As a preferred embodiment of the present application, as shown in the accompanying drawings, an inclined section 7 is arranged at the communication between the first groove body 1-1 and the passage 3, so as to enhance the flow efficiency of the liquid in the first groove body 1-1 into the second groove body 2-1, or to weaken the flow efficiency of the liquid in the second groove body 2-1 into the first groove body 1-1. This design can accelerate the lifting speed of the second deceleration strip 2, and is suitable for the scenario of continuous passing of vehicles. Figure 5

[0039] As a preferred embodiment of the present application, as shown in the accompanying drawings, an inclined section 7 is arranged at the communication between the first groove body 1-1 and the passage 3, so as to enhance the flow efficiency of the liquid in the first groove body 1-1 into the second groove body 2-1, or to weaken the flow efficiency of the liquid in the second groove body 2-1 into the first groove body 1-1. This design can accelerate the lifting speed of the second deceleration strip 2, and is suitable for the scenario of continuous passing of vehicles. Figure 6

[0040] The present application can achieve different deceleration effects according to the vehicle weight. This helps the front wheels to pass smoothly, and plays a role of preliminary warning. The larger contact area can improve the rolling efficiency, i.e., the first horizontal plate 1-3 moves downward by a short distance, and the second horizontal plate 2-3 moves upward by a long distance. The greater the load of the vehicle, the higher the lifting speed and height of the second deceleration strip 2, and the more obvious the warning effect on the driver. In the present application, the first deceleration strip 1 that is first rolled and the second deceleration strip 2 that is subsequently rolled have a linkage effect. When the vehicle reaches the first deceleration strip 1 without being braked to a proper speed, the front wheels of the vehicle first lift by a small height or have a lifting tendency, and the impact feedback on the driver is relatively weak. However, when the front wheels are subsequently impacted by the second deceleration strip 2, the impact feedback is greater than that when the vehicle passes through the second deceleration strip 2 at the same speed, and this can form a more obvious psychological stimulation on the driver. Therefore, the driver will actively brake to make the rear wheels pass smoothly through the deceleration strip, otherwise, the large vibration of the rear wheels can cause a large noise or affect the stability of the goods. Based on the above two effects, compared with the conventional deceleration strip with a constant height, the working frequency of the deceleration strip can be reduced, and the working life of the deceleration strip can be prolonged.

[0041] The above-mentioned embodiments are merely some embodiments of the present application, and are not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.​​
