Description

Technical Field

[0001] This invention relates to the field of speed bump technology, and more specifically to an intelligent speed bump. Background Technology

[0002] In modern transportation systems, speed bumps are a common traffic facility widely used in various road scenarios. They aim to improve traffic safety in specific areas by forcing vehicles to slow down. They are usually installed in areas with dense pedestrian and vehicle traffic, such as schools, hospitals, residential areas, and intersections, where there are strict speed limits. By causing vehicles to bump, they force drivers to reduce their speed, thereby avoiding safety accidents caused by excessive speed and ensuring the safe passage of pedestrians and vehicles.

[0003] Existing speed bumps, in terms of shape and structure, are mostly strip-shaped protrusions, generally made of materials such as rubber, plastic, or metal. Their cross-sections are mostly trapezoidal or triangular. They achieve the purpose of slowing down vehicles by increasing the friction between the vehicle's tires and the ground and compressing the tires, causing the vehicle to bump. However, the existing speed bumps have revealed obvious limitations in actual use. They are all fixed to the ground, which means that regardless of whether the passing vehicle meets the deceleration requirements, all vehicles will experience the strong bumps from the speed bumps. This situation can cause great discomfort to the driver, especially when there are vulnerable people such as the elderly or infants in the car, or when fragile items are stored. The bumps caused by the speed bumps are very likely to cause physical discomfort to the occupants, and in severe cases, may even cause items inside the car to break. In the long run, this not only affects the driving experience but also increases the additional psychological burden and potential risks for people traveling.

[0004] Therefore, it is of great importance to design an intelligent speed bump to solve the above-mentioned defects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention designs an intelligent speed bump. This speed bump aims to solve the technical problem that existing speed bumps fixed to the ground cause vehicles to experience severe bumps regardless of whether the vehicle meets the deceleration requirements, leading to discomfort and damage risks to passengers and property.

[0010] As a preferred embodiment of the present invention, the elastic speed bump is made of rubber material, the non-Newtonian fluid is made of starch and water, and reinforcing ribs are fixedly connected to both the left and right sides of the elastic speed bump.

[0011] As a preferred embodiment of the present invention, the telescopic component is any one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. A rubber protective sleeve is fixedly connected to the connection between the top of the retractable box and the elastic deceleration belt, and the elastic deceleration belt is slidably connected to the rubber protective sleeve. The front and rear sides of the lifting seat are slidably connected to the retractable box through limiting edges.

[0012] As a preferred embodiment of the present invention, box plates are fixedly installed on both the left and right sides of the shrink box, and the four corners of the box plates are fixedly connected to the shrink box by fixing bolts.

[0013] As a preferred embodiment of the present invention, the bottom of both the vehicle speed monitor and the infrared detector are fixedly connected to one end of the road surface via a support frame.

[0014] As a preferred embodiment of the present invention, each of the two sets of installation edges is fixedly connected to an installation edge at the opposite end of the shrink plate. The interior of each of the two sets of installation edges is fixedly connected to the road surface by multiple sets of assembly bolts. A hidden groove is provided at the connection between the interior of each of the two sets of installation edges and the multiple sets of assembly bolts. A metal protective sleeve is embedded inside the interior of each of the multiple sets of hidden grooves.

[0015] As a preferred embodiment of the present invention, rubber elastic seals are snapped at the connection between the two sets of shrink plates and the outer protective plate, and the two sets of rubber elastic seals are snapped with the shrink plates through T-shaped slots. Multiple sets of anti-slip ribs are fixedly connected to the top of the two sets of shrink plates.

[0016] As a preferred embodiment of the present invention, the outer protective plate is composed of a top plate, two sets of linkage plates and two sets of connecting plates. The top plate is located on top of the elastic speed bump. The two sets of linkage plates are rotatably connected to the front and rear ends of the top plate, respectively. The two sets of connecting plates are rotatably connected to the ends of the two sets of linkage plates that are far apart from each other. Both sets of connecting plates are slidably connected to the shrinkage groove. Shrinkage rods are fixedly installed inside the shrinkage groove and between the connecting plates, and at the left and right ends of the connecting plates.

[0017] As a preferred embodiment of the present invention, a metal reinforcing frame is fixedly connected inside the top plate, and first shock-absorbing holes are provided at both the front and rear ends of the top plate. Multiple sets of second shock-absorbing holes are provided inside the top plate and on the inner side of the metal reinforcing frame. Multiple sets of reflective strips are embedded on the surface of both sets of linkage plates. Both ends of the two sets of linkage plates are rotatably connected to the top plate and the connecting plate through a connecting shaft.

[0018] As a preferred embodiment of the present invention, the retractable rod includes a sleeve fixedly installed inside the retractable plate, a connecting rod slidably connected inside the sleeve, and the end of the connecting rod away from the sleeve is fixedly connected to the connecting plate. A second buffer spring is installed inside the sleeve, and a piston is fixedly connected at the connection between the connecting rod and the second buffer spring.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, through the coordinated design of the elastic speed bump, vehicle speed monitor, infrared detector, and shrink box, when the vehicle speed monitor detects an overspeeding vehicle, the telescopic component drives the lifting seat to the highest position, causing the non-Newtonian fluid inside the elastic speed bump to complete a liquid-solid phase change under high-speed impact, forming a rigid structure for forced deceleration. When a compliant vehicle passes, the telescopic component appropriately lowers its height, and the non-Newtonian fluid maintains its liquid properties to reduce bumps. The lifting seat is connected to the sliding sleeve through a linkage rod. When the sliding sleeve slides along the guide rod, the first buffer spring absorbs the impact energy. The deformation cavity provides deformation space for the non-Newtonian fluid, further reducing the height of the elastic speed bump to ensure smooth passage. When the telescopic component is working, it works in conjunction with the sliding seal of the rubber protective sleeve and the guiding effect of the limiting edge to achieve smooth reset. The box plate forms a protective shell through fixing bolts. The modular design facilitates maintenance. The vehicle speed monitor and infrared detector are fixed by a support frame and work together to judge the vehicle status, achieving an intelligent hierarchical control effect of forced deceleration of overspeeding vehicles and smooth passage of compliant vehicles.

[0021] 2. In this invention, through the cooperative design of the shrink plate and the outer protective plate, the top plate forms a foldable structure through the linkage plate and the connecting plate. The connecting plate slides along the shrink groove to unfold or retract. When the elastic speed bump is working, the outer protective plate provides external protection to prevent damage and breakage, and can change its state accordingly. The metal reinforcement frame enhances the pressure resistance of the top plate, and the first and second shock-absorbing holes disperse the impact stress. The connecting plate can move towards the inside of the shrink groove, and the connecting rod pushes the piston to slide in the sleeve, uniformly compressing the second buffer spring to absorb the impact energy when the outer protective plate unfolds or retracts, ensuring smooth operation of the mechanism and thus improving the service life of the speed bump. The reflective strip provides nighttime warning, and the connecting shaft and the mounting nut enable quick disassembly and assembly of the outer protective plate, facilitating assembly and maintenance.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0032] Example: Please refer to Figures 1-8 The present invention provides a technical solution:

[0033] A smart speed bump includes an elastic speed bump 2 embedded in the road surface 1. A vehicle speed monitor 3 and an infrared detector 4 are fixedly installed on one side of the road surface 1 and on the front and rear sides of the elastic speed bump 2, respectively. A shrink box 5 is fixedly installed inside the road surface 1 and at the bottom of the elastic speed bump 2. Shrink plates 6 are fixedly installed on the top of the road surface 1 and on both the front and rear sides of the elastic speed bump 2. An outer protective plate 7 is movably installed between the two sets of shrink plates 6 and on the outside of the elastic speed bump 2. Shrink grooves 8 are provided at the connection between the two sets of shrink plates 6 and the outer protective plate 7.

[0034] First, the elastic speed bump 2 is filled with a non-Newtonian fluid 201. The elastic speed bump 2 is made of rubber material, and the non-Newtonian fluid 201 is a mixture of starch and water. Reinforcing ribs 209 are fixedly connected to both sides of the elastic speed bump 2. A lifting seat 202 is fixedly connected to the bottom of the elastic speed bump 2. Telescopic components 203 are fixedly installed between the left and right ends of the bottom of the lifting seat 202 and the shrinkage box 5. Deformation cavities 204 are opened on both the front and rear sides inside the shrinkage box 5. Guide rods 205 are fixedly connected to the four corners at the bottom of the shrinkage box 5. The outer sides of the multiple sets of guide rods 205 are... A first buffer spring 206 and a sliding sleeve 207 are provided. A linkage rod 208 is installed between the sliding sleeve 207 and the lifting seat 202, and the two ends of the linkage rod 208 are rotatably connected to the sliding sleeve 207 and the lifting seat 202 respectively. The vehicle speed monitor 3 and the infrared detector 4 are installed on one side of the road surface 1 according to the actual road conditions, without affecting the normal passage of pedestrians and vehicles. The vehicle speed monitor 3 collects vehicle speed data in real time. When an overspeeding vehicle runs over it at high speed, a liquid-solid phase change is instantly completed to form a rigid deceleration structure. The bottom of the elastic deceleration band 2 is connected to the telescopic component 203 through the lifting seat 202. When the vehicle speed monitor 202 is in operation, the vehicle speed band 202 is activated. 3. When overspeed is detected, the telescopic component 203 drives the lifting seat 202 to raise the elastic deceleration band 2 to its highest position for forced deceleration; while when compliant vehicles pass, the height is appropriately lowered to maintain the liquid properties of the non-Newtonian fluid 201 and reduce bumps. The lifting seat 202 is connected to the sliding sleeve 207 through the linkage rod 208. When the sliding sleeve 207 slides along the guide rod 205, the first buffer spring 206 absorbs the impact energy, making the force distribution at the bottom of the lifting seat 202 uniform. After the lifting seat 202 is lowered, the deformation cavity 204 provides deformation space for the non-Newtonian fluid 201, allowing the liquid non-Newtonian fluid 201 to maintain its liquid state. The elastic speed bump 2 can be lowered by shrinking the inner part of the deformation cavity 204, allowing compliant vehicles to pass smoothly. The reinforcing ribs 209 strengthen the left and right structures of the elastic speed bump 2, improving its overall strength and lifespan. Finally, after the infrared detector 4 detects that a vehicle has passed, the elastic speed bump 2 is controlled to rise to its highest position to prepare for the next vehicle to pass. The elastic speed bump 2 containing non-Newtonian fluid 201, together with the buffer structure inside the shrink box 5, ensures the smoothness of the lifting and lowering movement, ultimately achieving the intelligent graded control effect of forced deceleration of speeding vehicles and smooth passage of compliant vehicles.

[0035] Then, the telescopic component 203 can be any one of a cylinder, hydraulic cylinder, or electric telescopic rod. A rubber protective sleeve 210 is fixedly connected to the connection between the top of the shrink box 5 and the elastic deceleration band 2, and the elastic deceleration band 2 and the rubber protective sleeve 210 are slidably connected. The front and rear sides of the lifting seat 202 are slidably connected to the shrink box 5 through the limiting edge 211. The height of the lifting seat 202 is controlled by the telescopic component 203. With the sliding seal of the rubber protective sleeve 210 and the guiding effect of the limiting edge 211, a smooth reset is achieved, while preventing mud and water from entering the shrink box 5 and ensuring operational reliability.

[0036] Furthermore, box panels 212 are fixedly installed on both the left and right sides of the shrink box 5. The four corners of the box panels 212 are fixedly connected to the shrink box 5 by fixing bolts 213. The box panels 212 are tightly fixed to the shrink box 5 by the fixing bolts 213 at the four corners, forming a stable protective shell. The modular design facilitates quick disassembly and assembly during later maintenance.

[0037] The bottom of both the vehicle speed monitor 3 and the infrared detector 4 are fixedly connected to one end of the road surface 1 via a support frame 301. The support frame 301 fixes the monitoring equipment to one end of the road surface 1, ensuring that the detection probe maintains the optimal working distance from the road surface 1. The vehicle speed monitor 3 collects the speed signal when the wheel passes through in real time, while the infrared detector 4 monitors the vehicle position. The data from both are used to determine the vehicle status.

[0038] Furthermore, each of the two sets of mounting edges 601 is fixedly connected to the opposite end of the shrink plate 6. The interior of each set of mounting edges 601 is fixedly connected to the road surface 1 by multiple sets of assembly bolts 602. Hidden grooves 603 are provided at the connection points between the interior of each set of mounting edges 601 and the multiple sets of assembly bolts 602. Metal protective sleeves 604 are embedded inside the multiple sets of hidden grooves 603. The mounting edges 601 are fixed to the road surface 1 by multiple sets of assembly bolts 602. The metal protective sleeves 604 in the hidden grooves 603 protect the connection points of the assembly bolts 602 and prevent mud and sand from eroding the assembly bolts 602, thereby improving the overall service life of the speed bump.

[0039] Furthermore, rubber elastic seals 605 are snapped into the connection points between the two sets of retractable plates 6 and the outer protective plate 7. Both sets of rubber elastic seals 605 are snapped into the retractable plates 6 through T-shaped slots 606. Multiple sets of anti-slip ribs 607 are fixedly connected to the top of the two sets of retractable plates 6. The rubber elastic seals 605 are snapped into the retractable plates 6 through T-shaped slots 606 to achieve quick disassembly and assembly, which is convenient for disassembly and maintenance. At the same time, the elastic seal at the outer protective plate 7 is maintained during the lifting and lowering process. The anti-slip ribs 607 form raised textures on the surface of the retractable plates 6, which increases the contact friction between the tire and the speed bump, significantly improving the grip of the vehicle when passing through and preventing slippage.

[0040] Furthermore, the outer protective plate 7 consists of a top plate 701, two sets of linkage plates 702, and two sets of connecting plates 703. The top plate 701 is located on top of the elastic speed bump 2. The two sets of linkage plates 702 are rotatably connected to the front and rear ends of the top plate 701, respectively. The two sets of connecting plates 703 are rotatably connected to the ends of the two sets of linkage plates 702 that are far apart from each other. Both sets of connecting plates 703 are slidably connected to the shrinkage groove 8. Shrinkage rods 704 are fixedly installed inside the shrinkage groove 8 between the connecting plates 703 and at the left and right ends of the connecting plates 703. The top plate 701 forms a foldable structure with the connecting plates 702 and the connecting plates 703. The connecting plates 703 slide along the shrinkage groove 8 to unfold or retract. When the elastic speed bump 2 is working, the outer protective plate 7 provides external protection to prevent damage and breakage, and can change its state accordingly.

[0041] Secondly, a metal reinforcing frame 705 is fixedly connected inside the top plate 701. First shock-absorbing holes 706 are opened at both the front and rear ends of the top plate 701. Multiple sets of second shock-absorbing holes 707 are opened inside the top plate 701 and on the inner side of the metal reinforcing frame 705. Multiple sets of reflective strips 708 are embedded on the surface of the two sets of linkage plates 702. Both ends of the two sets of linkage plates 702 are rotatably connected to the top plate 701 and the connecting plate 703 through the connecting shaft 709. The left and right ends of the connecting shaft 709 are threaded with mounting nuts 710. The metal reinforcing frame 705 improves the compressive strength of the top plate 701. The first shock-absorbing holes 706 and the second shock-absorbing holes 707 disperse the impact stress, thereby improving the service life of the speed bump. The reflective strips 708 can provide nighttime warning. The connecting shaft 709 and the mounting nuts 710 enable quick disassembly and assembly of the outer protective plate 7, which is convenient for assembly and maintenance.

[0042] Finally, the retraction rod 704 includes a sleeve 711 fixedly installed inside the retraction plate 6. A connecting rod 712 is slidably connected inside the sleeve 711, and the end of the connecting rod 712 away from the sleeve 711 is fixedly connected to the connecting plate 703. A second buffer spring 713 is installed inside the sleeve 711. A piston 714 is fixedly connected at the connection between the connecting rod 712 and the second buffer spring 713. The connecting plate 703 can move inward to the retraction groove 8. The connecting rod 712 pushes the piston 714 to slide inside the sleeve 711, uniformly compressing the second buffer spring 713, absorbing the impact energy when the outer protective plate 7 unfolds or retracts, and ensuring smooth operation of the mechanism.

[0043] In this embodiment, the specific implementation scenario is as follows: When the vehicle speed monitor 3 detects an overspeeding vehicle, the telescopic component 203 drives the lifting seat 202 to its highest position, causing the non-Newtonian fluid 201 inside the elastic speed bump 2 to undergo a liquid-solid phase change under high-speed impact, forming a rigid structure for forced deceleration. When a compliant vehicle passes, the telescopic component 203 appropriately lowers its height, and the non-Newtonian fluid 201 maintains its liquid properties to reduce bumps. The lifting seat 202 is connected to the sliding sleeve 207 via the linkage rod 208. When the sliding sleeve 207 slides along the guide rod 205, the first buffer spring 206 absorbs the impact energy. The deformation cavity 204 provides deformation space for the non-Newtonian fluid 201, further reducing the height of the elastic speed bump 2 to ensure a smooth passage. When the telescopic component 203 is working, it works in conjunction with the sliding seal of the rubber protective sleeve 210 and the guiding effect of the limiting edge 211 to achieve a smooth reset. The box plate 212 forms a protective shell through fixing bolts 213. The modular design facilitates maintenance. The vehicle speed monitor 3 and the infrared detector 4 are connected by a support... The support frame 301 is fixed and coordinates the judgment of vehicle status. The mounting edge 601 of the retractable plate 6 is fixed by the assembly bolt 602. The metal protective sleeve 604 in the hidden groove 603 prevents bolt corrosion. The rubber elastic seal 605 is quickly installed and removed through the T-shaped slot 606. The anti-slip rib 607 increases tire friction. The outer protective plate 7 is a foldable structure composed of the top plate 701, the linkage plate 702 and the connecting plate 703. When the elastic speed bump 2 is working, the outer protective plate 7 provides external protection to prevent damage and breakage. At the same time, it can change its state accordingly. The retractable rod 704 absorbs impact energy through the second buffer spring 713 in the sleeve 711. The metal reinforcing frame 705, together with the first shock absorption hole 706 and the second shock absorption hole 707, improves the pressure resistance, thereby improving the service life of the speed bump. The reflective strip 708 can provide nighttime warning. The whole operation process is simple and convenient. This invention achieves the intelligent graded control effect of forced deceleration of speeding vehicles and smooth passage of compliant vehicles through design.

[0044] Furthermore, the control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since the present invention is intended to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
