Description

Technical Field

[0001] This invention relates to the field of road speed bump technology, and more particularly to a rising speed bump suitable for urban roads. Background Technology

[0002] Speed ​​bumps achieve deceleration by influencing the driver's psychology. When a vehicle travels over a speed bump at a high speed, the intense vibration is transmitted from the tires through the body and seat to the driver. The vertical curve generates a vertical acceleration, producing strong physiological (including vibrational and visual) and psychological stimulation. With existing speed bumps, discomfort is experienced regardless of whether the vehicle is traveling at high or low speeds, creating an unfair situation. Furthermore, repeated exposure to speed bumps causes wear on the tires and damage to vehicle parts. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a speed bump that is suitable for urban roads. This speed bump can provide a better sense of security and ride comfort, prompting drivers to reduce their speed and reducing damage to vehicles.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that those skilled in the art can better understand the advantages and features of the present invention, thereby making a clearer definition of the scope of protection of the present invention. The embodiments described in this invention are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1-10 A speed bump for urban roads includes a triggering device, a force transmission device, a feedback device and a recovery device embedded in the road. The road includes a roadbed 14, a base course 13 above the roadbed 14 and an asphalt surface course 12 above the base course 13.

[0034] The triggering device and the feedback device are arranged at intervals, and a force transmission device and a recovery device are respectively provided between the triggering device and the feedback device, with the recovery device located above the force transmission device.

[0035] The triggering device includes a trigger block 7, trigger rods 23 located at both ends of the trigger block 7, and a compression spring damper 5 located below the trigger block 7.

[0036] In this embodiment, a single driving lane is used as a unit, and passenger cars are the main designed vehicles. The duration of the kinetic energy action is reflected in the speed of the triggering device. The height of the speed bump is adjusted by the force transmission device, and after the action is completed, the recovery device will restore it to its original state without affecting the normal driving of other vehicles.

[0037] Specifically, refer to Figure 2 The feedback device includes a liftable deceleration block 3 and fixed deceleration belts 1 on the left and right sides of the liftable deceleration block 3. The fixed deceleration belts 1 are fixedly connected to the asphalt surface layer 12 by fixing pins 2. A tension spring damper 6 is provided below the liftable deceleration block 3.

[0038] In this embodiment, under the action of the tension spring damper 6, the liftable deceleration block 3 can be driven to move up and down.

[0039] Specifically, refer to Figure 2 The force transmission device includes a matching lever 11, which is connected to the precast concrete trench 1503 via a support 27. One end of the matching lever 11 extends to the bottom of the trigger rod, and the other end of the matching lever 11 extends to the bottom of the liftable deceleration block 3.

[0040] In this embodiment, the lever principle is utilized, and a matching lever 11 is used. When the driver passes over the speed bump at a speed exceeding the limit, the front wheel activates the trigger device, causing the trigger block 7 and the trigger rod 23 below to move downward under the action of the compression spring damper 5, which drives the matching lever 11 to tilt downward, thereby causing the other end of the matching lever 11 to tilt upward, which in turn drives the liftable deceleration block 3 to move upward.

[0041] Specifically, refer to Figure 3The restoration device includes a first rotating rod 10 and a second rotating rod 16. Both the first rotating rod 10 and the second rotating rod 16 are connected to the precast concrete cover plate 1502 via bearings 17. One end of the first rotating rod 10 is provided with a first conical tooth 18, and a first gear 19 is provided on one side of the first conical tooth 18. The first gear 19 is connected to the precast concrete cover plate 1502 and meshes with the first conical tooth 18. The other end of the first rotating rod 10 is provided with a second conical tooth 20. One end of the second rotating rod 16 is provided with a third conical tooth 21, which meshes with the second conical tooth 20. The other end of the second rotating rod 16 is provided with a fourth conical tooth 22, and a second gear 9 is provided on one side of the fourth conical tooth 22. The second gear 9 is connected to the precast concrete undercut groove 1501 and meshes with the fourth conical tooth 22.

[0042] Specifically, refer to Figure 2 The trigger rod 23 is provided with a first rack 701 on the side near the first rotating rod 10, and the first rack 701 meshes with the first gear 19; the liftable deceleration block 3 is provided with a second rack 301 on the side near the second rotating rod 16, and the second rack 301 meshes with the second gear 9.

[0043] In this embodiment, through the combined action of rack, gear, and transmission rod, after the entire overspeed behavior is completed, the liftable deceleration block 3 moves downward under the action of the tension spring damper. At the same time, the second rack 301 drives the second gear 9 to rotate clockwise, and the fourth conical tooth 22 drives the second rotating rod 16 to rotate counterclockwise. The second rotating rod 16 drives the first rotating rod 10 to rotate clockwise through the engagement of the third conical tooth 21 and the second conical tooth 20. Finally, the first rotating rod 10 drives the trigger rod 23 to move upward to return to its original position through the engagement of the first conical tooth 18 and the first gear 19, achieving the effect of rapid reset.

[0044] Specifically, the trigger rod 23 on the side away from the first rotating rod 10 and the liftable deceleration block 3 on the side away from the second rotating rod 16 are provided with a number of roller assemblies 8, which are evenly distributed from top to bottom.

[0045] Specifically, refer to Figure 9 Each roller assembly 8 includes a handle 801 and a cover plate 802 connected to the handle 801. A roller 803 is mounted on the cover plate 802. A main roller 805 is sleeved on the roller 803. Side rollers 804 are provided on both sides of the main roller 805.

[0046] In this embodiment, several roller assemblies 8 are used to facilitate the up-and-down movement of the trigger rod 23 and the liftable deceleration block 3, making them stable and reliable.

[0047] Specifically, refer to Figure 2 The liftable deceleration block 3 is also provided with a limiting block 4 on the side away from the second rotating rod 16, and the base layer 13 is provided with a slot 1301 that engages with the limiting block 4.

[0048] In this embodiment, the limiting block 4 is engaged with the slot 1301, so that the recovery device can precisely hold the liftable deceleration block 3 by the cooperation of the limiting block 4 and the slot 1301, so that it can maintain the raised height and achieve the purpose of punishing speeding vehicles.

[0049] Among them, multiple pre-embedded pipes are provided between the triggering device and the feedback device, and the multiple pre-embedded pipes 15 are arranged at intervals.

[0050] In this embodiment, multiple pre-embedded pipes 15 are used to provide a platform for installing the force transmission device and the recovery device. After being spliced ​​together, they also serve to withstand external soil pressure and protect the force transmission device and the recovery device.

[0051] In addition, during the installation of this lifting speed bump, the concrete trench 1503 is dug out and installed, the lever is installed, then the concrete cover plate 1502 is laid at intervals, the force transmission device is installed, then the concrete inverted groove 1501 is installed, and finally the asphalt surface layer is laid on its surface; the installation is simple and orderly, and it is also easy to replace.

[0052] Working principle of the invention: Refer to Figure 10 When a driver exceeds the speed limit and passes over a speed bump, the front wheels activate the triggering device. This causes the trigger block 7 and the trigger rod 23 below it to move downwards under the action of the compression spring damper 5. This causes the matching lever 11 to tilt downwards, which in turn causes the other end of the matching lever 11 to tilt upwards. This, in turn, causes the liftable speed bump 3 to move upwards under the action of the tension spring damper 6. At this time, the restoring device, through the cooperation of the limit block 4 and the slot 1301, precisely locks the liftable speed bump 3, maintaining its raised height, thus penalizing the speeding vehicle. After the rear wheels pass over the speed bump, the compression spring damper 5, the tension spring damper 6, and the restoring device work simultaneously, causing the trigger block 7, the trigger rod 23 below it, and the liftable speed bump 3 to return to their original state. Conversely, when the speed limit is not exceeded, none of the devices react, and the vehicle passes over the speed bump smoothly.

[0053] In summary, this invention utilizes the lever principle and the cooperation of gears and rotating rods to achieve different driving experiences through speed control, reduce vehicle wear, and enhance the driver's awareness of slowing down.

[0054] The descriptions and practices disclosed in this invention are readily apparent and understandable to those skilled in the art, and various modifications and refinements can be made without departing from the principles of this invention. Therefore, any modifications or improvements made without departing from the spirit of this invention should also be considered within the scope of protection of this invention.
