[0001] This invention belongs to the technical field of speed bumps and traffic lights, specifically, it relates to a self-healing speed bump and traffic light device based on vehicle pressure power generation. Background Technology

[0002] In the field of road traffic safety, speed bumps are raised devices installed on road lanes to force vehicles to slow down. It is well known that speeding is a major cause of road traffic accidents, and speed bumps can reduce or prevent such accidents to a certain extent, playing a crucial role in road traffic safety. With the continuous increase in urban traffic and the number of cars, traffic congestion has become one of the most significant problems facing society today. Traditional traffic light systems are usually powered by the power grid, which leads to energy waste and environmental pollution. Furthermore, the fixed time intervals of traffic lights can cause unnecessary waiting times or traffic congestion in certain situations. Therefore, there is a need for a resource-saving, traffic-friendly, and easy-to-maintain and manage self-healing speed bump and traffic light device based on vehicle pressure power generation. Summary of the Invention

[0003] The purpose of this invention is to provide a self-healing speed bump and traffic light device based on vehicle pressure power generation that saves resources, facilitates traffic, and is easy to maintain and manage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The self-healing speed bump based on vehicle pressure power generation includes a left round head unit and a right round head unit arranged opposite each other, and several interconnected intermediate units arranged between the left round head unit and the right round head unit.

[0006] The intermediate unit includes a base plate, a front stop block, a rear stop block, an upper cover, a hydraulic power generation mechanism, and a gear power generation mechanism. The front stop block and the rear stop block are respectively arranged opposite to each other at the front and rear ends of the base plate. The hydraulic power generation mechanism and the gear power generation mechanism are both arranged on the base plate and located between the front stop block and the rear stop block.

[0007] The upper cover includes a cover plate and a cylindrical part. The upper surface of the cover plate is an arc surface, and the lower surface of the cover plate is a flat surface. The upper end of the cylindrical part is connected to the lower surface of the cover plate. The outer contour surface of the cylindrical part is provided with symmetrical racks. Several pressure-generating plates are provided on the lower surface of the cylindrical part. An installation hole is opened at the center of the lower surface of the cylindrical part. When a vehicle runs over the upper cover, pressure is applied to the pressure-generating plates, causing them to generate electricity.

[0008] The base plate is provided with mounting posts corresponding to the mounting holes, and a first return spring is provided on the mounting posts. The base plate and the upper cover are assembled and installed by the cooperation of the mounting posts and the mounting holes. There are two gear power generation mechanisms, which are respectively set on the left and right sides of the mounting posts. The gear power generation mechanism includes a first-stage gear shaft, a second-stage gear shaft, a first-stage large gear, a second-stage large gear, a first-stage small gear, a second-stage small gear, a generator gear, a gear generator, a front vertical plate, and a rear vertical plate. The front vertical plate and the rear vertical plate are arranged opposite each other, and the front vertical plate and the rear vertical plate are provided with corresponding first upper holes, second upper holes, first lower holes, and second lower holes. The first-stage gear shaft is installed through the first upper holes and second upper holes. The upper part between the front and rear vertical plates, the secondary gear shaft is installed on the lower part of the front and rear vertical plates through the first and second lower holes. The primary large gear is installed at the front end of the primary gear shaft, and the primary small gear is installed at the rear end of the primary gear shaft. The primary small gear meshes with the rack. The secondary large gear is installed at the rear end of the secondary gear shaft, and the secondary small gear is installed at the front end of the secondary gear shaft. The secondary small gear meshes with the primary large gear. The secondary large gear meshes with the generator gear. The generator gear is connected to the output shaft of the gear generator by a key. When the vehicle passes over the speed bump, it crushes the upper cover, causing the upper cover to move downwards, which in turn causes the rack to drive the gear generator to generate electricity through gear transmission.

[0009] The hydraulic power generation mechanism includes a reservoir bag, hydraulic oil, a hydraulic generator, and a reservoir tank. The reservoir bag is a circular bag filled with hydraulic oil. A flow port is provided on the side of the reservoir bag, and the hydraulic generator is connected to the hydraulic generator through a first flow pipe. The hydraulic generator is connected to the reservoir tank through a second flow pipe. Several second return springs are installed inside the reservoir bag. When a vehicle passes over a speed bump, the reservoir bag is squeezed, and the hydraulic oil enters the hydraulic generator through the first flow pipe, converting the hydraulic oil pressure into electrical energy. The hydraulic oil then enters the reservoir tank through the second flow pipe for temporary storage. When no vehicle passes, the reservoir bag returns to its original position under the action of the second return springs, allowing the hydraulic oil to flow from the reservoir tank back into the reservoir bag through the second and first flow pipes for secondary power generation.

[0010] The lower surface of the upper cover is provided with a first left pull ring and a first right pull ring on the left and right sides respectively. The base plate is provided with a second left pull ring corresponding to the first left pull ring and a second right pull ring corresponding to the first right pull ring. A first tension spring is installed between the first left pull ring and the second left pull ring, and a second tension spring is installed between the first right pull ring and the second right pull ring.

[0011] The lower surfaces of the left round-head unit, the middle unit, and the right round-head unit are provided with several grooves arranged in a front-to-back pattern. Several heating wires are arranged inside the bottom of the left round-head unit, the middle unit, and the right round-head unit. When the heating wires are energized, they heat the asphalt pavement, causing the uneven parts of the pavement to melt into the grooves and eliminate the gaps.

[0012] A first drainage ditch arranged on the left and right is provided at the connection between the base plate and the front stop block, and a second drainage ditch arranged on the left and right is provided at the connection between the base plate and the rear stop block. A first drainage groove connected to the first drainage ditch is provided on both the left and right sides of the front stop block, and a second drainage groove connected to the second drainage ditch is provided on both the left and right sides of the rear stop block.

[0013] The mounting post has a long strip block, and the mounting hole is a long strip hole set at the front and rear. The cylindrical part has a rotating hole, which allows the long strip block to enter the long strip hole, rotate and be supported. The first return spring is supported by the lower surface of the cylindrical part. When the vehicle passes over the speed bump, the upper cover compresses the first return spring downward, and the long strip block moves upward in the rotating hole.

[0014] The left round head unit and the right round head unit have the same structure, both including a connecting part and a round head, with the connecting part located between the round head and the middle unit.

[0015] The traffic light device includes a traffic light assembly set in the center of the intersection and speed bumps set at each intersection. The speed bumps are the self-healing speed bumps based on vehicle pressure power generation mentioned above. The electrical output terminals of the speed bumps are connected to the traffic light assembly and the energy storage box via wires. The energy storage box is connected to the traffic light assembly.

[0016] The traffic light assembly includes a traffic light base, traffic light bulbs, and casters. The casters are located at the bottom of the traffic light base, and a traffic light holder is mounted on the traffic light base. The traffic light bulbs are mounted on the traffic light holder.

[0017] This invention relates to a self-healing speed bump based on vehicle pressure power generation, incorporating a gear-driven power generation mechanism. When a vehicle passes over the speed bump, it crushes the upper cover, causing it to move downwards. This movement triggers a gear generator via gear transmission, and a hydraulic power generation mechanism is also included. When a vehicle passes over the speed bump, the reservoir bag is compressed, and hydraulic oil flows through a first circulation pipe into the hydraulic generator, converting the hydraulic oil pressure into electrical energy. The hydraulic oil then flows through a second circulation pipe into a reservoir for temporary storage. When no vehicle passes, the reservoir bag returns to its original position under the action of a second return spring, allowing the hydraulic oil to flow from the reservoir back into the reservoir bag through the second and first circulation pipes for secondary power generation. This design reduces vehicle speed while simultaneously achieving energy reuse and conservation, reducing reliance on traditional energy sources and lowering urban energy costs.

[0018] On the other hand, the traffic light device of this application includes a traffic light assembly set in the center of the intersection and speed bumps set at each intersection. The speed bumps are the self-healing speed bumps based on vehicle pressure power generation mentioned above. The electrical output terminals of the speed bumps are connected to the traffic light assembly and the energy storage box through wires. The energy storage box is connected to the traffic light assembly. This ensures that the power required by the traffic light comes entirely from the power generated by vehicles passing over the speed bumps, greatly saving the use of electricity.

[0019] Furthermore, the self-healing speed bump based on vehicle pressure power generation in this application has a self-healing function. Specifically, the lower surfaces of the left, middle, and right round-head units of this application are provided with several grooves arranged front and rear. Several heating wires are arranged inside the bottom of the left, middle, and right round-head units. When the heating wires are energized, they heat the asphalt pavement, causing uneven parts of the pavement to melt into the grooves and eliminate gaps. This greatly improves the durability and ease of maintenance of the speed bump, thereby reducing long-term maintenance costs. By reducing the frequency of replacement or repair, it not only saves resources but also reduces traffic disruption.

[0020] In summary, this invention can greatly save electricity resources, reduce vehicle speed, and achieve energy reuse. By setting heating wires, it greatly improves the durability and ease of maintenance of speed bumps, thereby reducing long-term maintenance costs and effectively solving the technical problem of the single function of existing speed bumps and traffic light devices.

[0029] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1-8As shown, the self-healing speed bump 40 based on vehicle pressure power generation includes a left round head unit 1 and a right round head unit 2 arranged opposite to each other, and several interconnected intermediate units 3 arranged between the left round head unit 1 and the right round head unit 2.

[0032] The intermediate unit 3 includes a base plate 4, a front stop block 5, a rear stop block 6, an upper cover 7, a hydraulic generator 26, and a gear generator 22. The front stop block 5 and the rear stop block 6 are respectively arranged opposite to each other at the front and rear ends of the base plate 4. The hydraulic generator 26 and the gear generator 22 are both arranged on the base plate 4 and located between the front stop block 5 and the rear stop block 6.

[0033] The upper cover 7 includes a cover plate portion 8 and a cylindrical portion 9. The upper surface of the cover plate portion 8 is set as an arc surface, and the lower surface of the cover plate portion 8 is set as a plane. The upper end of the cylindrical portion 9 is connected to the lower surface of the cover plate portion 8. A toothed portion 10 with left and right symmetry is provided on the outer contour surface of the cylindrical portion 9. A plurality of pressure generating plates 11 are provided on the lower surface of the cylindrical portion 9. A plurality of grooves are provided on the lower surface of the cylindrical portion 9. The pressure generating plates 11 are set in the grooves, totaling 40 plates. Each pressure generating plate 11 corresponds to a groove. When subjected to pressure from the upper cover 7, these pressure generating plates 11 will deform and thus stimulate the piezoelectric effect inside them, converting mechanical energy into electrical energy. The electrical energy is transmitted to the external circuit through its electrical output terminal. Part of it is used for power supply and part of it is stored, realizing the recovery and reuse of energy. A mounting hole 12 is provided at the center of the lower surface of the cylindrical part 9; when a vehicle runs over the upper cover 7, pressure is applied to the pressure generator 11, causing the pressure generator 11 to generate electricity; the number of pressure generators 11 can be adjusted as needed to adapt to different pressure and power requirements. The pressure generator 11 is installed inside the speed bump 40 and is protected, able to adapt to various environmental conditions, ensuring the stable operation of the system; the base plate 4 is provided with a mounting post 13 corresponding to the mounting hole 12, and the mounting post 13 is provided with a first reset spring. Spring 14, through the cooperation of mounting post 13 and mounting hole 12, assembles and installs base plate 4 and upper cover 7; there are two gear generators 22, respectively set on the left and right sides of mounting post 13. The gear generator 22 includes a first-stage gear shaft 15, a second-stage gear shaft 16, a first-stage large gear 17, a second-stage large gear 18, a first-stage small gear 19, a second-stage small gear 20, a generator gear 21, a gear generator 22, a front vertical plate 23, and a rear vertical plate 24; the front vertical plate 23 and the rear vertical plate 24 are arranged opposite each other, the front vertical plate 23 and The rear vertical plate 24 is provided with corresponding first upper hole, second upper hole, first lower hole, and second lower hole. The first-stage gear shaft 15 is installed on the upper part between the front vertical plate 23 and the rear vertical plate 24 through the first upper hole and the second upper hole. The second-stage gear shaft 16 is installed on the lower part between the front vertical plate 23 and the rear vertical plate 24 through the first lower hole and the second lower hole. The first-stage large gear 17 is installed at the front end of the first-stage gear shaft 15, and the first-stage small gear 19 is installed at the rear end of the first-stage gear shaft 15. The first-stage small gear 19 meshes with the rack part 10. The secondary large gear 18 is installed at the rear end of the secondary gear shaft 16, and the secondary small gear 20 is installed at the front end of the secondary gear shaft 16. The secondary small gear 20 meshes with the primary large gear 17 to realize power transmission and amplify the transmission ratio. The secondary large gear 18 meshes with the generator gear 21, which is keyed to the output shaft of the gear generator 22. When the vehicle passes over the speed bump 40, it crushes the upper cover 7, causing the upper cover 7 to move downwards. This causes the rack section 10 to drive the gear generator 22 to generate electricity via gear transmission. As the rotor rotates, the magnetic field inside the gear generator 22 changes, cutting magnetic field lines and thus generating current in the generator coil.The gear configuration on the primary gear shaft 15 and the secondary gear shaft 16 amplifies the transmission ratio and increases the rotational speed to meet the input requirements of the generator. This mechanism of the gear generator 22 converts the mechanical energy of the vehicle passing over the speed bump 40 into electrical energy. Its electrical output terminals are connected to an external circuit to transmit the generated electrical energy to where it is needed, such as traffic lights or energy storage systems.

[0034] The hydraulic generator 26 comprises a reservoir 25, hydraulic oil, a hydraulic generator 26, and a reservoir 27. The reservoir 25 is an annular structure filled with hydraulic oil. A flow port is located on the side of the reservoir 25, and it is connected to the hydraulic generator 26 via a first flow pipe. The hydraulic generator 26 is connected to the reservoir 27 via a second flow pipe. Several second return springs are installed inside the reservoir 25. When a vehicle passes over a speed bump 40, the reservoir 25 is compressed, and the hydraulic oil flows through the first flow pipe into the hydraulic generator 26, converting the hydraulic oil pressure into electrical energy. The hydraulic oil then flows through the second flow pipe into the reservoir 27 for temporary storage. When no vehicle passes, the reservoir 25 returns to its original position under the action of the second return springs, allowing the hydraulic oil to flow from the reservoir 27 back into the reservoir 25 via the second and first flow pipes for secondary power generation. After a vehicle passes, the springs inside the reservoir 25 help it quickly return to its original position, ready to respond to the next pressure change. The design of the reservoir 25 ensures a rapid response to pressure changes as a vehicle passes over the speed bump 40 and a quick reset after the pressure dissipates. The reservoir 27 allows for temporary storage of hydraulic oil after it flows through the hydraulic generator 26, and enables secondary power generation upon its return to the reservoir 25, increasing energy recovery efficiency. The closed-loop design of the hydraulic system not only improves energy utilization but also facilitates system maintenance and monitoring. The electrical energy generated by the hydraulic generator 26 can be transmitted to an external circuit via electrical output terminals to power traffic lights, streetlights, or energy storage systems. The entire hydraulic generator 26 is mounted inside the base of the speed bump 40 block, reducing the impact of external environmental factors and protecting the system's stability and durability.

[0035] The lower surface of the upper cover 7 is provided with a first left pull ring 28 and a first right pull ring 29 on the left and right sides respectively. The base plate 4 is provided with a second left pull ring 30 corresponding to the first left pull ring 28 and a second right pull ring corresponding to the first right pull ring 29. A first tension spring 31 is installed between the first left pull ring 28 and the second left pull ring 30, and a second tension spring is installed between the first right pull ring 29 and the second right pull ring.

[0036] Several grooves 32 arranged in a front-to-back pattern are provided on the lower surfaces of the left round head unit 1, the middle unit 3, and the right round head unit 2. Several heating wires are arranged inside the bottom of the left round head unit 1, the middle unit 3, and the right round head unit 2. When the heating wires are energized, they heat the asphalt pavement, causing the uneven parts of the pavement to melt into the grooves 32 and eliminate the gaps.

[0037] A first drainage ditch 33 is provided at the connection between the base plate 4 and the front stop 5, and a second drainage ditch 34 is provided at the connection between the base plate 4 and the rear stop 6. First drainage channels 35 connecting the first drainage ditch 33 are provided on both sides of the front stop 5, and second drainage channels 36 connecting the second drainage ditch 34 are provided on both sides of the rear stop 6. This design aims to effectively manage and guide the water flow entering from the gaps in the upper cover 7 of the speed bump 40, ensuring smooth drainage and preventing water accumulation from damaging the speed bump 40 or affecting its performance. It also efficiently collects and guides the water flow. The first drainage ditch 33, first drainage channel 35, second drainage ditch 34, and second drainage channel 36 allow water to flow smoothly in and further guide the water flow through the interior of the base, forming a continuous drainage path. This effectively ensures that the water flow smoothly from the gaps in the upper cover 7 of the speed bump 40 into the first drainage ditch 33 and second drainage ditch 34, and then discharges through the first drainage channel 35 and second drainage channel 36, thus achieving effective drainage.

[0038] The mounting post 13 is provided with a long strip block 37. The mounting hole 12 is provided with long strip holes at the front and rear. The cylindrical part 9 is provided with a rotating hole, so that the long strip block 37 enters the long strip hole, rotates and is supported. The first return spring 14 is supported by the lower surface of the cylindrical part 9. When the vehicle passes over the speed bump 40, the upper cover 7 compresses the first return spring 14 downward, and the long strip block 37 moves upward in the rotating hole.

[0039] The left round head unit 1 and the right round head unit 2 have the same structure, both including a connecting part 38 and a round head 39, with the connecting part 38 disposed between the round head 39 and the middle unit 3.

[0040] The speed bump of this application can be directly installed on asphalt pavement. It utilizes the potential energy generated when vehicles pass over it, converting it into electrical energy through its built-in power generation mechanism and storing it. This process not only provides energy for the speed bump 40 itself to achieve self-repair but also provides power to the road traffic light system, reducing dependence on external power sources. After enduring repeated pressure and friction from passing vehicles, gaps inevitably appear between the speed bump 40 and the road surface. These gaps accelerate damage to the speed bump 40 and increase the bumpy feeling when vehicles pass over it. This invention automatically repairs these gaps through a self-heating mechanism, reducing maintenance needs and improving driving smoothness. Furthermore, the installation-free design of the device allows for rapid deployment on roads without complex construction, making it suitable for various road surface environments.

[0041] The self-healing speed bump 40 based on vehicle pressure power generation of this invention is equipped with a gear generator 22. When a vehicle passes over the speed bump 40, it crushes the upper cover 7, causing the upper cover 7 to move downwards. This causes the rack part 10 to drive the gear generator 22 to generate electricity via gear transmission. A hydraulic generator 26 is also included. When a vehicle passes over the speed bump 40, the reservoir 25 is compressed, and hydraulic oil enters the hydraulic generator 26 through the first flow pipe. The hydraulic oil pressure is converted into electrical energy. The hydraulic oil then enters the reservoir 27 through the second flow pipe for temporary storage. When no vehicle passes, the reservoir 25 returns to its original position under the action of the second return spring, allowing the hydraulic oil to flow from the reservoir 27 back into the reservoir 25 through the second and first flow pipes for secondary power generation. This design reduces vehicle speed while also achieving energy reuse and conservation, reducing dependence on traditional energy sources and lowering urban energy costs.

[0042] Furthermore, the self-healing speed bump 40 based on vehicle pressure power generation in this application has a self-healing function. Specifically, several grooves 32 arranged front-to-back are formed on the lower surfaces of the left round head unit 1, the middle unit 3, and the right round head unit 2. Several heating wires are arranged inside the bottom of the left round head unit 1, the middle unit 3, and the right round head unit 2. When the heating wires are energized, they heat the asphalt pavement, causing uneven parts of the pavement to melt into the grooves 32, eliminating gaps. This application has good weather resistance and can resist the effects of sun and rain, temperature changes, and severe weather. It can greatly improve the durability and ease of maintenance of the speed bump 40, thereby reducing long-term maintenance costs. By reducing the frequency of replacement or repair, it not only saves resources but also reduces traffic disruption.

The speed bumps 40 are the self-healing speed bumps 40 based on vehicle pressure power generation mentioned above. The electrical output terminals of the speed bumps 40 are connected to the traffic light assembly 41 and the energy storage box through wires. The energy storage box is connected to the traffic light assembly 41.

[0045] Traffic light assembly 41 includes a traffic light base, traffic light bulbs, and moving wheels. The moving wheels are located at the bottom of the traffic light base, and a traffic light bracket is installed on the traffic light base. The traffic light bulbs are installed on the traffic light bracket.

[0046] The traffic light device of this application includes a traffic light assembly 41 installed at the center of an intersection and speed bumps 40 installed at each intersection. The speed bumps 40 are the self-healing speed bumps based on vehicle pressure power generation mentioned above. The electrical output terminals of the speed bumps 40 are connected to the traffic light assembly 41 and a power storage box via wires. The power storage box is connected to the traffic light assembly 41. This ensures that the power required by the traffic light comes entirely from the power generated by vehicles passing over the speed bumps 40, greatly saving the use of electrical resources.

[0047] This invention can greatly save electricity resources, reduce vehicle speed, and achieve energy reuse. By setting heating wires, it greatly improves the durability and ease of maintenance of the speed bump 40, thereby reducing long-term maintenance costs and effectively solving the technical problem of the single function of existing speed bumps 40 and traffic light devices.
