Description

Technical Field

[0001] This utility model belongs to the field of bench technology, and in particular relates to an energy-saving outdoor bench. Background Technology

[0002] Outdoor benches are widely installed in urban public spaces such as parks, bus stops, and train stations. As important public facilities, they provide pedestrians with temporary rest and waiting facilities, and are an indispensable part of the urban public service system.

[0003] However, these outdoor benches are exposed to the natural environment for extended periods, enduring various climatic conditions such as rain, snow, and low temperatures. Currently, the vast majority of outdoor benches lack any heating devices, which can cause discomfort and even health risks for users in low temperatures. When users sit on cold benches, body heat is rapidly lost, leading to a drop in body temperature. For the average person, this may only be temporary discomfort, but for hemorrhoid sufferers, cold stimulation can worsen local blood circulation problems, easily triggering or exacerbating their condition and hindering recovery. Elderly individuals, due to declining bodily functions and weaker thermoregulation, may experience joint pain and other health problems from prolonged sitting on cold benches. Furthermore, the low body temperature can lower their immune system, increasing their risk of developing other illnesses.

[0004] As people's demands for comfort and health in public facilities continue to increase, the shortcomings of traditional outdoor benches in cold environments are becoming increasingly apparent. There is an urgent need for an outdoor bench that can provide users with a suitable temperature while ensuring energy conservation. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0038] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0039] Example 1:

[0040] like Figures 1-5 As shown, this embodiment provides an energy-saving outdoor bench including a seat 1, a backrest 2, and legs 3:

[0041] Uprights 4 are located on both sides of the top of the backrest 2;

[0042] Solar panel 5 is installed on one side of column 4. Solar panel 5 is used to receive sunlight and convert it into electricity.

[0043] The outer casing 51 is located at the bottom of the solar panel 5;

[0044] Battery 52 is disposed inside housing 51;

[0045] The controller 6 is housed in the integrally formed housing 51 at the bottom of the solar panel 5 and is electrically connected to the battery 52.

[0046] Heating element 7 is installed inside seat 1 and connected to battery 52 via power supply 71;

[0047] Waterproof sheet 8 is covered on seat 1 and backrest 2;

[0048] Temperature sensor 9 is used to detect the outdoor temperature and send the detected data to controller 6.

[0049] This technical solution addresses the problem of traditional outdoor benches causing users' body temperature to drop and health deterioration for specific groups (such as hemorrhoid sufferers and the elderly) in cold environments due to the lack of heating devices. It provides an energy-saving outdoor bench by using solar panels 5 to collect and store electrical energy, combined with intelligent temperature sensor 9 to ensure that heating element 7 operates at low temperatures, maintaining a comfortable body temperature for users. This improves the comfort and health protection of the outdoor bench, while also utilizing solar energy for energy conservation, making it suitable for outdoor settings such as parks and bus stops.

[0050] Working principle: Solar panel 5 receives sunlight, converts light energy into electrical energy, and transmits it to battery 52 inside casing 51 for storage, powering subsequent heating elements 7, etc., thus achieving energy-saving power supply by utilizing solar energy and reducing reliance on external power sources. Temperature sensor 9 continuously monitors the outdoor temperature and sends the temperature data to controller 6 in real time as a basis for determining whether to start heating. Controller 6 receives data from temperature sensor 9. When it determines that the outdoor temperature is below a set threshold (which can be adjusted as needed to ensure reasonable start-up under different climates), it controls power supply 71 to connect battery 52 to heating element 7. Heating element 7 works to generate heat, which is transferred through seat 1 to warm the user. If the temperature is above the threshold, controller 6 cuts off the power supply, and heating element 7 stops, avoiding energy waste. Waterproof cloth 8 covers seat 1 and backrest 2 to protect internal heating elements 7, battery 52, etc., from rain and snow corrosion, extending the equipment's lifespan and allowing the bench to stably adapt to complex outdoor environments. Column 4 supports components such as solar panel 5 and casing 51, ensuring the overall structural stability.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, an over-discharge protection module 10 is installed between the battery 52, the power supply 71, and the heating element 7; a pressure sensor 11 is provided on the seat 1, and the pressure sensor 11 is electrically connected to the controller 6.

[0052] In this technical solution, based on the original energy-saving outdoor bench that uses solar power and low-temperature trigger heating, an over-discharge protection module 10 is added to prevent the battery 52 from being damaged due to excessive discharge, extend its service life, and ensure the stability of the bench's power supply. A pressure sensor 11 is added to enable heating to be activated only when "someone is sitting and the temperature is low", providing precise heating on demand, further saving energy, while improving the targeted heating service for users and optimizing the user experience.

[0053] Working principle: Solar panel 5 converts solar energy into electrical energy and stores it in battery 52 to power heating element 7, etc. Over-discharge protection module 10 monitors the battery 52's power output in real time. When it detects that the discharge is close to the over-discharge threshold (e.g., 20%-30% of battery 52's capacity, set according to battery 52 characteristics), it automatically cuts off the circuit between battery 52, power supply 71, and heating element 7 to prevent over-discharge. Power supply is restored after solar replenishment or manual intervention (if necessary), ensuring the battery 52's lifespan and system stability. Pressure sensor 11 is located on seat 1. When someone sits down, the pressure change triggers the sensor, transmitting an electrical signal to controller 6. Controller 6 combines the data from temperature sensor 9. If the outdoor temperature is lower than the set value and pressure sensor 11 detects someone, it controls power supply 71 to connect battery 52 and heating element 7 to start heating. When no one is sitting down, even at low temperatures, heating element 7 does not work, ensuring precise energy saving and making the heating service more suitable for actual use scenarios. Temperature sensor 9 continuously monitors the ambient temperature, and pressure sensor 11 monitors the sitting status. The data from both are aggregated in real time by controller 6. The controller 6 judges according to the preset logic (low temperature + someone sitting). If the condition is met, it instructs the power supply 71 to turn on and the heating element 7 to heat up. If any condition is not met (such as the temperature reaches the standard or no one is sitting), the power supply is cut off, so that all components work together to ensure the user's heating needs, while also achieving energy saving and equipment protection.

[0054] Example 2:

[0055] This embodiment provides an energy-saving outdoor bench, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] like Figures 1-3 As shown, in this embodiment, the optimized column 4 connected to the solar panel 5 includes a guide cylinder 41 and a telescopic rod 42 that slides with the guide cylinder 41. The telescopic rod 42 is connected to the outer shell 51 integrally formed with the solar panel 5, and an adjustment mechanism 12 is used to adjust the relative position of the telescopic rod 42 and the guide cylinder 41.

[0057] In this technical solution, the column 4 connecting the solar panel 5 is designed as a sliding fit structure between the guide cylinder 41 and the telescopic rod 42, and equipped with an adjustment mechanism 12, which allows for flexible adjustment of the height of the solar panel 5. The aim is to enable the solar panel 5 to better adapt to the angle of sunlight at different times and seasons, improve solar energy collection efficiency, increase the power reserve of the battery 52, ensure a stable power supply for the heating element 7, optimize the energy utilization effect of the energy-saving outdoor bench, and ensure its reliable operation in various environments.

[0058] Working principle: The support column 4 consists of a guide cylinder 41 and a telescopic rod 42, which slide together to provide linear movement space for adjusting the position of the solar panel 5. The telescopic rod 42 is connected to the integrally formed outer shell 51 of the solar panel 5, allowing the solar panel 5 to slide up and down relative to the guide cylinder 41 with the telescopic rod 42. When the adjustment mechanism 12 (which can be in the form of an electric push rod, a manual knob screw, etc., if electric, it is powered by a battery 52 or an external small power supply and controlled by the controller 6; if manual, it is convenient for maintenance personnel to operate on-site) is working, it pushes or pulls the telescopic rod 42 to slide within the guide cylinder 41, changing the length of the telescopic rod 42 extending out of the guide cylinder 41, thereby adjusting the height of the solar panel 5. At the same time, because the telescopic rod 42 is connected to the outer shell 51 of the solar panel 5, with the help of structural design (such as the top of the telescopic rod 42 being rotatable for angle adjustment), it can also help change the tilt angle of the solar panel 5, allowing the solar panel 5 to face a direction more conducive to receiving sunlight.

[0059] When the position of the solar panel 5 needs to be adjusted, the adjustment mechanism 12 operates to change its height and angle, increasing the area exposed to sunlight and the duration of sunlight reception. The solar panel 5 receives more light energy, converts it into more electrical energy, and increases the amount of energy stored in the battery 52. ​​This provides a more stable and sufficient power source for subsequent heating elements 7, improving the overall energy efficiency and operational performance of the bench. It also ensures that the heating element 7 can operate reliably in low-temperature environments, meeting the heating needs of users.

[0060] like Figure 1 and Figure 3 As shown, in this embodiment, the optimized adjustment mechanism 12 includes:

[0061] The frame 121 is mounted on the guide cylinder 41;

[0062] Cylinder 122 is mounted on frame 121;

[0063] A connecting plate 123 is mounted on the telescopic rod 42, and the piston rod of the cylinder 122 is connected to the connecting plate 123.

[0064] In this technical solution, based on the adjustable structure of the solar panel 5 and the column 4, an adjustment mechanism 12 driven by a cylinder 122 is used to adjust the height of the solar panel 5 more conveniently, stably, and efficiently. Utilizing the linear drive characteristics of the cylinder 122, the relative position of the telescopic rod 42 and the guide cylinder 41 is precisely controlled, allowing the solar panel 5 to quickly adapt to changes in the angle of sunlight, improving solar energy collection efficiency, ensuring the energy supply of the bench, and optimizing the synergy between energy saving and heating functions.

[0065] Working principle: The frame 121 is fixed on the guide cylinder 41, providing mounting support for the cylinder 122. The cylinder 122 is mounted on the frame 121, and its piston rod extension is connected to the connecting plate 123 of the telescopic rod 42, forming a drive transmission path. When the height of the solar panel 5 needs to be adjusted, the piston rod of the cylinder 122 extends or retracts. When the piston rod extends, it pushes the connecting plate 123, causing the telescopic rod 42 to slide upward along the guide cylinder 41, and the solar panel 5 moves upward accordingly. When the piston rod retracts, it pulls the connecting plate 123, causing the telescopic rod 42 to slide downward along the guide cylinder 41, and the solar panel 5 moves downward. By controlling the extension and retraction of the piston rod of the cylinder 122, the relative position of the telescopic rod 42 and the guide cylinder 41 can be precisely adjusted to achieve the height adjustment of the solar panel 5. Driven by cylinder 122, the adjustment process is stable and responsive. It can adjust the height of solar panel 5 in a timely manner according to changes in light (such as through linkage with light sensor or timer program) to make it more aligned with sunlight, increase the amount of light captured, improve the efficiency of solar energy conversion into electrical energy, allow battery 52 to store more power, provide sufficient power for heating element 7 to work at low temperatures, ensure the reliable operation of the heating function of energy-saving outdoor bench, and enhance the overall practicality and energy saving.

[0066] Example 3:

[0067] This embodiment provides an energy-saving outdoor bench, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] like Figure 1 and Figure 2 As shown, in this embodiment, an optimized canopy 13 is provided between the two columns 4, and the canopy 13 is inclined from front to back.

[0069] In this technical solution, a canopy 13 sloping from front to back is added between the two uprights 4 of the energy-saving outdoor bench, mainly to improve the comfort and practicality of the bench. On the one hand, the canopy 13 provides rain and sun protection for users, preventing them from getting wet in the rain and blocking direct sunlight on sunny days, reducing discomfort caused by rain or sun exposure. On the other hand, the canopy 13 prevents rainwater from directly wetting the seat 1, keeping it dry, which is convenient for users to sit on and also reduces the corrosion of internal components such as the heating element 7 by rainwater, extending the service life of the equipment. At the same time, in conjunction with the previous heating and other functions, it further optimizes the user experience of the outdoor bench.

[0070] Working Principle: The canopy 13 is installed between the two uprights 4, and its front-to-back sloping structural design is the core. When it rains, rainwater falls on the canopy 13. Due to the angle of the canopy 13, the rainwater flows backward along the surface of the canopy 13 and eventually flows behind the backrest 2, instead of dripping or flowing forward, thus preventing the user's legs from getting wet. On sunny days, the canopy 13 can block sunlight from directly hitting the user and the seat 1, providing shade and reducing the high temperature generated on the surface of the seat 1 due to sun exposure, making the user more comfortable. At the same time, because of the canopy 13, rainwater cannot directly hit the seat 1, reducing the chance of the seat 1 getting wet. This ensures that the user can always sit on a dry seat 1 and also protects the internal heating elements 7 and other structures of the seat 1 from rainwater immersion, maintaining their normal working condition. Together with other functions of the bench, this improves the overall practicality and reliability.

[0071] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the optimized backrest 2 is provided with lighting lamps 14 on both the upper left and right sides, and the lighting lamps 14 are connected to the power supply 71; the column 4 is provided with a support rod 15, and the support rod 15 is rotatably provided with a rotating sleeve 16, and the rotating sleeve 16 is connected to the lighting lamp 14.

[0072] In this technical solution, lighting lamps 14 are installed on the upper left and right sides of the backrest 2 of the energy-saving outdoor bench. This is mainly to improve the usability and safety of the bench in low-light or nighttime environments. On the one hand, the lighting lamps 14 provide illumination for users resting or waiting for transportation, making it easier for them to view items, read, and perform other activities, avoiding inconvenience caused by dim lighting. On the other hand, the light makes the bench area more visible, reducing the occurrence of accidents such as pedestrian collisions at night. The rotating connection design between the swivel sleeve 16 and the support rod 15 allows users to adjust the illumination angle of the lighting lamps 14 according to their actual needs, so that the light is better focused on the required area, further improving the practicality of the lighting.

[0073] Working Principle: The lighting lamp 14 is connected to the power supply 71, which is powered by the energy converted from solar panels 5 and stored in the battery 52. ​​This ensures that the lighting lamp 14 can work normally in outdoor environments without an external power source, conforming to the concept of energy conservation. In low-light or nighttime environments, the lighting lamp 14 can be turned on (automatically triggered by a light sensor or manually controlled) to provide illumination around the bench and the user's activity area. The support rod 15 is fixed to the column 4, and the rotating sleeve 16 is fitted onto the support rod 15 and connected to the lighting lamp 14. Since the rotating sleeve 16 can rotate relative to the support rod 15, the user can rotate the rotating sleeve 16 to change the direction of illumination of the lighting lamp 14. For example, when the user needs to illuminate the surface of the seat 1, the angle of the lighting lamp 14 can be adjusted downwards; when the user needs to illuminate the road ahead, the angle can be adjusted forwards. This adjustable structure makes the lighting more flexible and adaptable to different lighting needs in various scenarios. While providing convenience, it also makes full use of the energy converted from solar energy, which aligns with the energy-saving characteristics of the bench.

[0074] like Figure 1 and Figure 2 As shown, in this embodiment, the optimized design includes a mosquito-repellent lamp 17 at the top of the backrest 2, located below the ceiling 13.

[0075] In this technical solution, a mosquito-repellent lamp 17 is installed at the top of the backrest 2 of the energy-saving outdoor bench, located below the canopy 13. This is primarily to improve the comfort and experience of users when using the bench outdoors. In outdoor environments, there are many mosquitoes, especially in the evening and at night. Mosquito bites can be bothersome and may even spread diseases. The mosquito-repellent lamp 17 effectively repels or kills surrounding mosquitoes, reducing their disturbance and allowing users to rest or wait on the bench with greater peace of mind. Simultaneously, because the mosquito-repellent lamp 17 is located below the canopy 13, the canopy 13 protects it from rain, snow, and other natural elements, extending its lifespan and ensuring its stable mosquito-repellent effect.

[0076] Working Principle: The mosquito repellent lamp 17 typically uses light of a specific wavelength (such as ultraviolet light) to attract mosquitoes. When mosquitoes approach, they are killed or driven away through electric shock, sticky traps, or the release of mosquito repellent agents. Its power source is the same as other electrical components of the bench: solar panel 5 converts electrical energy and stores it in battery 52, which then powers the mosquito repellent lamp 17 via power supply 71, thus meeting energy-saving requirements. When in operation, the mosquito repellent lamp 17 is activated by the battery 52, emitting specific light to attract surrounding mosquitoes, thereby creating a relatively mosquito-free area and protecting the user from mosquito interference. The canopy 13, located above the mosquito repellent lamp 17, is angled to provide rain and sun protection and a relatively stable working environment for the lamp. It prevents rainwater from directly hitting the lamp, preventing damage from water ingress and ensuring continuous and effective operation. Combined with other functions of the bench, this further enhances the practicality and comfort of the outdoor bench.

[0077] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
