Description

Technical Field

[0001] This application relates to the field of public seating technology, specifically a step-powered public seat. Background Technology

[0002] Public seating is an indispensable facility in urban public spaces, providing people with places to rest. However, traditional public seating has a single function, only meeting the basic need of "sitting". With the development of smart cities and Internet of Things technologies, people have put forward higher requirements for the functionality of public facilities, such as charging mobile phones and providing lighting.

[0003] Existing new public seats attempt to integrate charging ports or LED light strips, but their power source usually relies on mains power or solar energy. Relying on mains power wiring has problems such as complex construction, high cost, and fixed and inflexible location. Solar energy is greatly affected by weather, day and night and geographical location. It cannot effectively supply power in rainy weather or at night, and in urban areas with high-rise buildings, the lighting conditions are often poor, making it inconvenient to use.

[0004] Therefore, this application provides a self-powered public seat that can be stepped on to solve the above problems. Utility Model Content

[0005] This application provides a self-powered public seat that can be stepped on, aiming to solve the problem that existing new public seats mentioned in the background art attempt to integrate charging interfaces or LED light strips, but their power sources usually rely on mains power or solar energy. Relying on mains power wiring has problems such as complex construction, high cost, and fixed and inflexible location, while solar energy is greatly affected by weather, day and night and geographical location, and cannot effectively supply power in rainy weather or at night. Moreover, in urban areas with high-rise buildings, the lighting conditions are often poor, making it inconvenient to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a step-powered public seat, comprising a seat body, wherein a power generation mechanism is provided inside the ground on the front side of the seat body; To address the issue that existing new public seating attempts to integrate charging ports or LED light strips, but whose power sources typically rely on mains power or solar energy, the mains power approach suffers from complex construction, high costs, and inflexible fixed locations. Solar energy, on the other hand, is greatly affected by weather, day / night cycles, and geographical location, failing to provide effective power during cloudy or rainy weather or at night, and often suffers from poor lighting conditions in urban areas with high-rise buildings, making it inconvenient to use. This invention proposes a power generation mechanism comprising a protective shell flush with the ground. A foot pedal is located on the top of the protective shell, and a rack is positioned at the center of the bottom of the foot pedal. Drive gears rotatably mesh on both sides of the rack, and a rotating shaft is fixedly connected inside the drive gears. This rotating shaft is rotatably connected to the protective shell, and a transmission gear set is located on one side of the rotating shaft. The output shaft of the transmission gear set is equipped with a one-way bearing. A miniature straight... The miniature DC generator has its output terminal fixedly connected to a one-way bearing, and a battery is installed inside the protective shell. Multiple sets of return springs are fixedly connected between the bottom of the pedal and the inside of the protective shell. When a pedestrian sits on the main body of the seat and steps on the pedal, the force exerted by the pedal pushes the rack at the bottom to mesh with the drive gear, causing the shaft to rotate and driving the transmission gear set to rotate. The transmission gear set drives the one-way bearing to rotate, thus causing the miniature DC generator to rotate and generate electricity. The electricity is stored in the battery. During the descent of the pedal, the return spring at the bottom is compressed, and the rebound force of the return spring causes the pedal to return to its original shape, making it convenient for reuse. This device efficiently converts the kinetic energy of pedestrians' footsteps into electrical energy, is simple and quick to operate, provides stable power support, and is convenient for pedestrians to rest and meet their needs.

[0007] Preferably, in order to solve the problem of pedal movement stability, a movable rod is fixedly connected to the bottom of the pedal, and a fixed rod is fixedly connected inside the protective shell. The movable rod is located inside the fixed rod and is slidably connected to the fixed rod. The pedal pushes the movable rod at the bottom to slide inside the fixed rod, which can improve the stability of the pedal movement and make it convenient to use.

[0008] Preferably, in order to solve the problem of pedal movement distance, limit blocks are fixedly connected to both sides of the pedal, and limit grooves are opened on both sides of the protective shell. The limit blocks are set inside the limit grooves and are slidably connected to the limit grooves. The pedal drives the limit blocks to slide inside the limit grooves. Through the set limit grooves, the movement distance of the pedal can be limited, which is convenient to use.

[0009] Preferably, to address the issue of user convenience, the armrests on both sides of the seat body are equipped with power indicator lights, and charging ports are located below the top of the armrests on both sides of the seat body. Wireless charging pads are also provided on both sides of the seat body. The power indicator lights can display the power level, the charging ports can charge mobile phones, and the wireless charging pads can conveniently charge mobile phones wirelessly, making it easy to use.

[0010] Preferably, to address the power support issue, the micro DC generator is electrically connected to a storage battery, and the storage battery is electrically connected to a power indicator light, a charging interface, and a wireless charging pad. The electrical connection between the micro DC generator and the storage battery allows the power generated by the micro DC generator to be stored, and the storage battery can provide power support to the power indicator light, the charging interface, and the wireless charging pad.

[0011] Preferably, to address the issue of convenient lighting, an LED light strip is provided on the top of the protective shell, and the battery is electrically connected to the LED light strip. The LED light strip can provide illumination, preventing the foot pedal, which is slightly higher than the ground, from tripping over the user, and making it convenient to use.

[0012] The seat's main body allows pedestrians to sit on it and press the pedals. The pressure from the pedals pushes a rack at the bottom, which in turn engages with a drive gear. This causes the shaft to rotate, driving a transmission gear set, which in turn rotates a one-way bearing. This, in turn, causes a miniature DC generator to rotate and generate electricity, which is stored in a battery. As the pedals descend, they compress a return spring at the bottom, allowing the pedals to return to their original position for reuse. This design efficiently converts the kinetic energy of pedestrian footsteps into electrical energy, is simple and quick to operate, provides stable power support, and is convenient for pedestrians to rest and use.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example 1 This embodiment provides a step-powered public seat, such as... Figure 1-4 As shown, the self-powered public seat includes a seat body 1, and a power generation mechanism 2 is installed inside the ground on the front side of the seat body 1. The set-up power generation mechanism 2 can easily and efficiently convert the kinetic energy of pedestrians' footsteps into electrical energy. It is simple and quick to operate, can provide stable power support, and is convenient for pedestrians to rest and meet their needs.

[0017] Specifically, the power generation mechanism 2 includes a protective shell 21 that is flush with the ground and located inside the ground. A foot pedal 22 is provided on the top of the protective shell 21. A rack 23 is provided at the center of the bottom of the foot pedal 22. Drive gears 24 are rotatably meshed on both sides of the rack 23. A rotating shaft 25 is fixedly connected inside the drive gear 24. The rotating shaft 25 is rotatably connected to the protective shell 21. A transmission gear set 26 is provided on one side of the rotating shaft 25. A one-way bearing 27 is provided on the output shaft of the transmission gear set 26. A micro DC generator 28 is provided inside the protective shell 21. The output end of the micro DC generator 28 is fixedly connected to the one-way bearing 27. A battery 29 is provided inside the protective shell 21. Multiple sets of return springs 30 are fixedly connected between the bottom of the foot pedal 22 and the inside of the protective shell 21. In use, the pedestrian sits on the seat body 1 and steps on the pedal 22 with both feet. This causes the pedal 22 to push the rack 23 at its bottom, which in turn engages with the drive gear 24. This causes the shaft 25 to rotate, driving the transmission gear set 26 to rotate. The transmission gear set 26 then drives the one-way bearing 27 to rotate, which in turn causes the micro DC generator 28 to rotate and generate electricity. The electricity is stored in the battery 29. As the pedal 22 descends, it compresses the return spring 30 at its bottom. The rebound force of the return spring 30 returns the pedal 22 to its original position, making it easy to reuse. This allows for convenient use of the pedal 22 and facilitates the movement of pedestrians. The kinetic energy of pedaling is efficiently converted into electrical energy, and the operation is simple and quick. It can provide stable power support, facilitate pedestrian rest, and meet pedestrian usage needs. It is easy to use. The protective shell 21 is level with the ground, and the pedal 22 is slightly higher than the ground by 2-3 cm. The transmission gear set 26 adopts multi-stage gear transmission with a transmission ratio range of 10:1 to 20:1, which can convert the low-speed reciprocating motion of the pedal into high-speed rotational motion suitable for the operation of the micro DC generator 28. The gear module is preferably 0.5 to 1.5, and the material is nylon or metal alloy to balance wear resistance and transmission efficiency. The stiffness coefficient of the return spring 30 is 10. The pressure ranges from N / mm to 30 N / mm, with a preload of 5 mm to 15 mm and a maximum compression of no more than 50 mm, to accommodate the range of human foot pressure (approximately 200 N to 600 N) and ensure that the pedal can quickly return to its original position after being stepped on. The protective shell 21 and the pedal 22 are made of stainless steel or engineering plastic. The protective shell has a sealing rating of no less than IP64 to prevent rainwater and dust from entering. The surface of the pedal 22 is provided with anti-slip texture and has a load-bearing capacity of no less than 150 kg. The power generation mechanism 2 is fixed to the ground concrete structure through a pre-embedded flange. The top of the protective shell 21 is provided with an openable maintenance cover for easy maintenance or replacement of internal components.

[0018] Furthermore, a movable rod 31 is fixedly connected to the bottom of the pedal 22, and a fixed rod 32 is fixedly connected inside the protective shell 21. The movable rod 31 is located inside the fixed rod 32, and the movable rod 31 is slidably connected to the fixed rod 32. The pedal 22 pushes the movable rod 31 at the bottom to slide inside the fixed rod 32, which can improve the stability of the pedal 22 and make it convenient to use.

[0019] Furthermore, limit blocks 33 are fixedly connected to both sides of the pedal 22, and limit grooves 34 are opened on both sides of the protective shell 21. The limit blocks 33 are set inside the limit grooves 34 and are slidably connected to the limit grooves 34. The pedal 22 drives the limit blocks 33 to slide inside the limit grooves 34. Through the limit grooves 34, the movement distance of the pedal 22 can be limited, making it convenient to use.

[0020] The seat body 1 has power indicator lights 35 on both sides of the armrests, and charging ports 36 are located below the top of the armrests on both sides of the seat body 1. Wireless charging pads 37 are located on both sides of the seat body 1. The power indicator lights 35 can display the power level, the charging ports 36 can charge mobile phones, and the wireless charging pads 37 can conveniently charge mobile phones wirelessly. The battery 29 is a lithium-ion or lithium iron phosphate battery with a rated voltage of 12 V and a capacity of 10 Ah to 30 Ah. The charging port 36 has an output voltage of 5 V / 2 A, and the wireless charging pad 37 has an output voltage of 5 W to 15 W.

[0021] Specifically, the micro DC generator 28 is electrically connected to the battery 29, and the battery 29 is electrically connected to the power indicator light 35, the charging interface 36, and the wireless charging board 37. The micro DC generator 28 and the battery 29 can store the power generated by the micro DC generator 28 and provide power support to the power indicator light 35, the charging interface 36, and the wireless charging board 37 through the battery 29.

[0022] Furthermore, the top of the protective shell 21 is equipped with an LED light strip 38, and the battery 29 is electrically connected to the LED light strip 38. The LED light strip 38 can provide illumination, preventing the step pedal 22, which is slightly higher than the ground, from tripping the human body and making it convenient to use.

[0023] It should be noted that the micro DC generator 28, battery 29, power indicator light 35, and wireless charging board 37 are existing devices, and their working principle, size, and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model 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. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0024] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
