Description

Technical Field

[0001] This invention relates to the field of bus shelter technology, specifically a self-cleaning bus shelter that can be used for both heating and cooling. Background Technology

[0002] Bus shelters are public transportation facilities located at urban bus stops, providing passengers with basic services such as shade, rain shelter, and rest. They typically consist of a roof, pillars, benches, and advertising light boxes, and have an open or semi-open structure. As an important part of the urban road landscape, bus shelters not only serve the practical function of guiding passenger flow and improving the travel experience, but also act as a window showcasing the city's civilized image and public service level. With the continuous improvement of urban public transportation systems and the increasing travel demands of citizens, the function of bus shelters is expanding from simple protection to humanization and intelligence. Their environmental comfort, cleanliness, and all-season applicability have become important indicators for measuring the quality of modern urban transportation services.

[0003] Chinese patent CN214462983U discloses a comfortable bus shelter. It features a rotating platform that rotates 180 degrees by pressing one side, preventing passengers from getting their clothes dirty when they sit down. To clean dust from the soft padding on the rotating platform, a dust removal block can be pulled to one side, causing a slider to move along a groove and clean the dust from the padding. However, in this patent, only the rotating platform rotates; the seats themselves do not. Dust still adheres to the seat surface, soiling passengers' clothes. Furthermore, the rotating platform's structure is not stable enough, prone to shaking, deformation, or even breakage after prolonged use. Cleaning relies on manually pulling the dust removal block, failing to automatically clean dust from the seats and advertising boards. Additionally, the shelter lacks temperature control, failing to meet passengers' needs for high-quality, comfortable waiting in different seasons, and requires further development and improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning bus shelter that can be used for both heating and cooling, in order to solve the problems that existing bus shelter benches are prone to dust accumulation and soiling of passengers' clothes, rely on manual cleaning methods and cannot achieve automatic cleaning, and lack temperature regulation functions.

[0010] Furthermore, the U-shaped movable support mounting bracket is provided with straight bushings at the positions corresponding to the first guide plug rod and the second guide plug rod, and the rotating support mounting plate is provided with straight bushings at the positions corresponding to the positioning support plug rod.

[0011] Furthermore, the linear transmission mechanism is a structure in which a drive motor is equipped with a transmission gear that meshes with a transmission rack.

[0012] Furthermore, distance sensors are provided on the bottom horizontal end of the lifting support mounting plate and the inner surface of the horizontal end of the U-shaped support mounting plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention completely solves the technical pain points of existing flip seats, such as being thin, easily shaking and deforming, by constructing a three-in-one structural system of "power rotation - mechanical limit - bottom support". The first rotating motor, in conjunction with rotation, drives the seat to achieve a smooth 180-degree spatial posture switch. The arc-shaped structures at both ends of the seat's longitudinal direction not only prevent interference with the support connection plate during rotation but also meet the natural leg extension and comfort needs of passengers when seated. When the seat is horizontal, a positioning insertion hole is provided at one of its horizontal ends. The first telescopic device drives the positioning support insertion rod to accurately insert into this hole, thus forming a double rigid limit on the seat in both the axial and circumferential directions, completely eliminating the risk of shaking when passengers sit down. Simultaneously, the rotating support plate driven by the second rotating motor on the L-shaped support connection plate can rotate synchronously to its bottom surface when the seat is horizontal, forming a surface contact support. This ensures that the force on the seat is evenly transmitted to the support base plate, effectively avoiding the risk of deformation or breakage caused by single-point stress on the rotating shaft after long-term use, thus meeting the needs of high-frequency, heavy-load public use scenarios in bus shelters.

[0014] 2. This design achieves a comfortable waiting experience with both heating and cooling through the differentiated functional chambers on both sides of the seat. One side of the seat features a heating chamber specifically designed for winter warmth, using carbon fiber heating wires as the core heating element. This, combined with a heat-conducting and temperature-dissipating plate, ensures uniform heating across the entire seat surface. A temperature sensor enables precise temperature control. Furthermore, a nano-aerogel felt insulation layer, insulating mica paper, and an insulating and thermally conductive silicone layer form multiple layers of insulation and heat protection, improving heat utilization, reducing outdoor heat loss, and ensuring electrical safety for outdoor use. The other side of the seat features an air supply chamber that, when rotated 180 degrees... Designed for summer use, the system utilizes a centrifugal duct fan in conjunction with a semiconductor cooling chip to deliver cool air evenly through the outlet. This provides a continuous supply of cool air during the hot summer months, effectively reducing the temperature of the contact surface and alleviating stuffiness. A metal filter screen is also installed to prevent dust or other foreign objects from clogging the air duct. The two sides are completely independent and do not interfere with each other. After rotation and switching, both sides can lock their working posture through a positioning and plug-in structure. This allows for dual micro-environmental regulation capabilities, including heating in winter and air supply in summer, without increasing the floor space. This significantly expands the environmental adaptability and humanized service level of the bus shelter facilities.

[0015] 3. This solution automates the cleaning of benches and billboard surfaces, eliminating the limitations of manual cleaning in existing bus shelters, significantly reducing the labor costs of public facility maintenance, and greatly improving cleaning efficiency. A linear transmission mechanism drives the U-shaped moving support frame to move smoothly laterally, enabling the cleaning components to cover the entire cleaning area of ​​the benches and billboards. For bench cleaning, a lifting device drives the first cleaning brush to rise and fall vertically to fit the bench surface, while a third rotary motor drives the first cleaning brush to rotate and sweep away dust. For billboard cleaning, a second telescopic device drives the second cleaning brush to feed laterally to fit the surface, while a fourth rotary motor drives the second cleaning brush to rotate, achieving comprehensive cleaning of the billboard. During the cleaning process, a vacuum cleaner simultaneously uses the first and second dust collection boxes to draw and collect the swept dust under negative pressure, effectively preventing secondary pollution caused by dust. A distance sensor ensures precise positioning of the cleaning location, guaranteeing optimal contact between the cleaning brush and the surface to be cleaned, ensuring stable cleaning results, and perfectly adapting to the long-term use requirements of high-dust outdoor environments.

The surface of the insulating and heat-insulating mica paper 517 has a serpentine groove, and carbon fiber heating wires 518 are coiled and embedded in the serpentine groove. An insulating and thermally conductive silicone layer 519 is covered on top of the carbon fiber heating wires 518 by a casting coating process. A thermally conductive heat-dissipating plate 520 made of aluminum alloy is attached to the top of the insulating and thermally conductive silicone layer 519 by thermally conductive silicone grease. A temperature sensor is embedded in the thermally conductive heat-dissipating plate 520. A flame-retardant cushioning pad layer 521 made of flame-retardant polyurethane foam is laid on the upper surface of the thermally conductive heat-dissipating plate 520 by a flame-retardant and environmentally friendly adhesive. A polyvinyl chloride synthetic leather fabric layer 522 is fixed on the top of the flame-retardant cushioning pad layer 521 by a hot-pressing composite process.

[0026] Working principle: This device uses solar photovoltaic modules installed on the top of the protective roof to capture natural sunlight and convert it into electrical energy stored in the battery. The control device monitors the power status in real time and prioritizes the use of clean energy when there is sufficient sunlight. If continuous cloudy or rainy weather causes the battery voltage to be insufficient, the system will automatically switch to the mains power grid to ensure that the temperature control and cleaning functions can operate stably in any climate.

[0027] To meet the actual needs of seasonal climate changes, the seat's working status can be automatically or remotely adjusted to achieve precise switching between "heating" and "air supply" modes. The specific working principle is as follows: First, unlocking: After the switching command is issued, the first telescopic device retracts the positioning support plug rod, releasing the axial limit. At the same time, the second rotary motor drives the bottom rotary support plate to rotate to the avoidance position. Then, performing the flipping operation: The first rotary motor drives the seat to flip 180 degrees in spatial posture through the rotating shaft. The seat edge adopts an arc structure design to ensure smooth and interference-free rotation. Finally, heavy load locking: After flipping into place, the first telescopic device drives the support plug rod to accurately insert into the positioning plug hole on the side of the seat. At the same time, the bottom support plate resets, forming a support structure with the bottom of the seat, ensuring the stability and firmness of the seat structure when carrying multiple passengers, solving the pain points of traditional flipping structures being prone to shaking and deformation.

[0028] Winter heating mode: When the heating chamber is flipped to the top, the internal carbon fiber heating wires are energized, and the heat is evenly distributed through the heat-conducting heat equalization plate. Combined with the flame-retardant cushioning layer, it provides a comfortable touch. The built-in temperature sensor can achieve constant temperature control, while the bottom nano aerogel insulation layer effectively locks in the heat and avoids energy waste. Summer cooling mode: When the air supply chamber is flipped to the top, the centrifugal duct fan starts and works with the semiconductor cooling chip to generate a cool airflow; the cool airflow is evenly delivered through the air box outlet, blowing cool air to the legs and support strips of waiting passengers, significantly improving waiting comfort. The metal filter screen can effectively block external dust and debris, keeping the inside of the air duct clean.

[0029] During preset off-peak hours, the automatic protective door of the storage box opens, and the cleaning component performs automated cleaning operations. The linear transmission mechanism drives the U-shaped moving support mounting frame to move laterally, allowing the cleaning component to cover the entire area of ​​the benches and billboards. When cleaning the benches, the lifting device drives the first cleaning brush to rise and fall vertically to fit the bench surface, while the third rotary motor drives the first cleaning brush to rotate and sweep away dust. When cleaning the billboards, the second telescopic device drives the second cleaning brush to feed laterally to fit the board surface, while the fourth rotary motor drives the second cleaning brush to rotate, achieving comprehensive cleaning of the billboards. During the cleaning process, the vacuum cleaner uses the first and second dust collection boxes to simultaneously draw and collect the swept dust under negative pressure, effectively avoiding secondary pollution caused by dust. With the help of a distance sensor, the cleaning position is accurately positioned to ensure the best fit between the cleaning brush and the surface to be cleaned, ensuring both cleaning depth and avoiding mechanical damage, thus achieving a consistently clean waiting environment.
