Description

Technical Field

[0001] This invention relates to the field of outdoor energy storage equipment and application technology, and in particular to an outdoor energy storage counter for sales and its usage method. Background Technology

[0002] With the booming development of new retail models, diversified outdoor sales scenarios such as mobile outdoor vending, rural markets, outdoor exhibitions, and temporary sales in the countryside are increasing, placing higher demands on the mobility, functionality, and environmental adaptability of outdoor sales counters. However, the design and function of existing sales counters still fall short of meeting the actual needs of outdoor sales and have many technical shortcomings, which are analyzed in detail below: Traditional fixed sales counters are mostly built with wood, metal or mixed materials. The structural design is relatively simple, and the core consists of a countertop, cabinet and supporting legs.

[0003] The countertop is mainly used for product display and transactions, the cabinet provides basic storage space, and the support legs provide fixed support. These counters are usually installed in fixed sales locations such as shopping malls and store entrances. They lack mobility and are completely unsuitable for the needs of mobile outdoor sales, making it difficult to meet the requirements of today's diverse outdoor sales scenarios.

[0004] While existing outdoor sales counters have made some improvements in mobility, they still face the core challenge of power supply. Most still rely on traditional power grids, and outdoor sales locations are often situated in remote rural areas, suburban regions, and temporary exhibition venues—places with insufficient grid coverage or unstable power supply. The instability of grid power directly leads to the malfunction of critical sales equipment such as lighting, electronic displays, and small refrigeration units, severely impacting the smooth operation of outdoor sales activities. Furthermore, prolonged reliance on grid power incurs high electricity costs, which become a significant economic burden for operators in large-scale, long-term outdoor sales activities. In addition, the energy consumption patterns of traditional grid power supply contradict the concepts of green, low-carbon, and sustainable development, placing considerable pressure on the environment.

[0005] In terms of human-centered design, existing outdoor sales counters also suffer from serious deficiencies. Outdoor sales staff need to stand or walk for extended periods, easily leading to fatigue. However, most existing outdoor sales counters lack dedicated rest areas for sales staff. Even those counters that provide simple seating often only offer basic comfort and lack temperature regulation features such as cooling or heating. In hot summer conditions, the seat surfaces become too hot, making it difficult for sales staff to sit for long periods; in cold winter conditions, the seats are too cold and offer no warmth, failing to provide comfortable resting conditions. This results in persistent fatigue for sales staff, directly impacting subsequent work efficiency and the quality of sales service.

[0006] Meanwhile, existing improvements to bank counters are mostly focused on specific indoor scenarios. For example, the bank counter disclosed in CN116427818A is designed to improve the efficiency of bank staff in sorting and counting banknotes, and is only suitable for fixed indoor work scenarios in banks. Its structure and function cannot solve core issues such as power supply, outdoor rest areas, and environmental adaptability for outdoor sales counters, and therefore cannot be directly applied or referenced in the design of outdoor sales counters.

[0007] Specifically, existing technologies have the following problems and shortcomings: 1. Electricity Dependence: Existing outdoor sales counters are highly dependent on traditional power grids, making them unusable in remote or unstable power supply areas. This dependence not only limits the geographical scope of sales activities but also increases the risk of sales losses due to power outages.

[0008] 2. High operating costs: Using traditional grid power requires paying high electricity bills, especially for long-term, large-scale outdoor sales activities, where energy costs become a significant burden for operators. This not only reduces sales profits but also limits the sustainability and scalability of sales activities.

[0009] 3. Environmental pressure: The use of traditional energy sources does not align with the concept of sustainable development and places certain pressures on the environment. With increasing global awareness of environmental protection, finding green and renewable energy solutions has become an urgent need.

[0010] 4. Poor sales staff experience: Most existing outdoor sales counters do not consider the rest needs of sales staff. Standing or walking for long periods can easily lead to sales staff fatigue, affecting work efficiency and sales quality. Even if simple seats are provided near some counters, these seats often lack cooling or heating functions, failing to provide comfortable rest conditions for sales staff in high or low temperature environments.

[0011] Among the published patents, for example, CN116427818A proposes a design scheme for a bank counter. This scheme improves the work efficiency of staff through a specific structure, but it does not address the issues of energy self-sufficiency for outdoor sales counters or the improvement of the rest environment for sales staff. Therefore, this patent differs significantly from the present invention in terms of technical field and application scenario.

[0012] In summary, existing outdoor sales counters have significant shortcomings in terms of power supply, operating costs, environmental impact, and sales staff experience. This invention addresses these issues by proposing an innovative energy storage counter for outdoor sales and its usage method. It aims to achieve energy self-sufficiency by integrating high-efficiency flexible solar panels and an energy storage system, while simultaneously improving the rest environment for sales staff and enhancing the overall efficiency and sustainability of sales activities. Summary of the Invention

[0013] The technical problem to be solved by this invention is to provide an energy storage counter for outdoor sales and its usage method, which solves the problem that most existing outdoor sales counters rely on traditional power grids for power supply. In remote or unstable power supply areas, the stability of power supply cannot be guaranteed, resulting in the inability of sales equipment to operate normally and high energy costs, which is not in line with the concept of sustainable development. In addition, existing outdoor sales counters lack dedicated comfortable rest areas designed for sales staff. Even if simple seats are set up, they do not have cooling or heating functions, and cannot provide comfortable rest conditions in extreme temperatures, which affects the work efficiency and sales quality of sales staff.

[0014] To achieve the above technical objectives, the present invention adopts the following technical solution: This invention provides an outdoor energy storage counter for sales, which includes a counter body, an energy storage component, and a condensation device.

The output end of the first telescopic pump is driven to one side of the bottom end of the umbrella rib, and the output end of the second telescopic pump is driven to the other side of the bottom end of the umbrella rib. An adjustment key is installed on the inner wall of one of the cabinet doors. The adjustment key can control the operation of the first and second telescopic pumps. By adjusting the extension and retraction state of the two telescopic pumps, and coordinating the rotation of the ball bearing and the ball groove, the angle and shape of the umbrella rib can be flexibly adjusted, thereby changing the light-receiving angle of the flexible solar panel.

[0016] The condensing unit provides a comfortable rest area for sales staff. It includes a backrest, a condenser, and an on / off switch. A swivel seat is rotatably connected to the bottom of the backrest. The condenser is installed inside the counter body. Condensation pipes are installed inside both the backrest and the swivel seat. The two ends of the condenser pipes pass through one side of the backrest and the counter body, respectively, and are connected to the water outlet and water inlet of the condenser to form a closed refrigeration cycle system. The on / off switch is installed on the inner wall of one of the cabinet doors and is adjacent to the adjustment switch. The on / off switch can control the start and stop of the condenser and realize the temperature adjustment of the backrest and the swivel seat.

[0017] The outdoor energy storage counter of the present invention has a reasonable structural design, is easy to operate, and is suitable for the needs of various outdoor sales scenarios. Its specific usage method is as follows: Step 1, Moving and Fixing: Using the self-locking casters at the bottom of the counter body, push the energy storage counter to the target outdoor sales location, and then lock the self-locking casters to prevent the counter from moving during use and ensure the stability of the counter; Step 2, Energy Storage Component Debugging: Operate the adjustment key on the inner wall of the cabinet door to control the first and second telescopic pumps to extend and retract, causing the umbrella ribs to rotate around the ball in the groove. At the same time, the slide plate slides laterally along the top of the partition plate. Adjust the angle and shape of the umbrella ribs to adjust the flexible solar panel to the optimal light-receiving angle and ensure maximum solar energy absorption efficiency. Step 3, Solar Energy Storage and Power Supply: Flexible solar panels absorb solar energy in outdoor sunlight and efficiently convert it into electrical energy. The electrical energy is stored in the energy storage battery inside the counter body through the charging controller. The energy storage battery provides stable power support for various electrical equipment in the counter, ensuring the normal operation of sales equipment such as lighting, electronic display screens, and refrigeration equipment. Step 4, Rest Area Use: When sales staff need to rest during work, they can rotate the swivel chair from the bottom of the backrest to a suitable angle, operate the on / off button to start the condenser, and the condenser will compress the refrigerant and send it into the condenser pipe inside the backrest and swivel chair. The refrigerant will absorb heat as it flows in the condenser pipe, lowering the temperature of the backrest and swivel chair, allowing the sales staff to sit and rest. After resting, operate the on / off button again to turn off the condenser, rotate the swivel chair back to its original position around the bottom of the backrest, and store it to save outdoor space. Step 5, Item Storage and Retrieval: Before sales, items can be categorized and stored in storage boxes inside the counter and storage compartments on the inner walls of the cabinet doors according to their type, quantity, and frequency of use. The transparent storage compartments make it easy to quickly view loose tools and small items. During the sales process, items can be retrieved directly by pulling out the storage boxes and opening the storage compartments, which is convenient and improves sales efficiency. Step 6, Equipment Reset and Movement: After the outdoor sales event ends, operate the adjustment key to reset the first and second telescopic pumps, which will restore the umbrella frame and flexible solar panels to their initial state. Turn off all electrical equipment, organize and store the remaining merchandise, unlock the self-locking casters, and push the energy storage counter to the designated storage location.

[0067] In the preferred embodiment, during step 2, when the first telescopic pump 68 and the second telescopic pump 69 are running, they drive the umbrella rib 61 to rotate around the bead 65 within the ball groove 64. Simultaneously, the sliding plate 67 slides laterally along the top of the partition plate 2, thereby adjusting the angle and shape of the umbrella rib 61. This configuration, through the coordinated operation of the first and second telescopic pumps, allows for flexible changes in the angle and shape of the umbrella rib. The design of rotating around the bead and sliding laterally makes the adjustment process smoother and more stable, allowing for precise control of the umbrella rib position and meeting the needs for sun shading and power generation in different scenarios. This adjustment method is simple to operate, can quickly adapt to environmental changes, and improves the flexibility and practicality of the equipment.

[0068] In the preferred embodiment, in step 4, the rotatable seat 92 can be rotated to a comfortable angle according to usage needs. After resting, the on / off button 95 is operated to turn off the condenser 9, and the rotatable seat 92 is rotated around the bottom of the backrest 91 for storage. With these settings, users can freely adjust the angle of the rotatable seat according to their own needs to obtain a comfortable resting posture. Operating the on / off button to turn off the condenser saves energy and avoids unnecessary energy consumption. Rotating the rotatable seat for storage saves space, making the equipment neater and more organized when not in use, facilitating subsequent use and movement, and improving the overall user experience and space utilization.

[0069] In summary, this invention proposes an energy storage counter for outdoor sales and its usage method. This solution effectively addresses several challenges in the outdoor sales field, including unstable power supply, high operating costs, and insufficient rest conditions for sales personnel. Addressing the issue that traditional outdoor sales counters rely on the traditional power grid for power, making normal operation difficult in remote or power-unstable areas, and the high electricity costs further increase operating costs, this invention, for the first time, integrates a flexible solar panel 62 using high-efficiency monocrystalline silicon solar cells into the outdoor sales counter 1. This achieves energy self-sufficiency, significantly reducing dependence on the traditional power grid, and is particularly suitable for remote areas and regions with unstable power supply.

[0070] In terms of technical implementation, the counter body 1 of the present invention is made of high-strength, corrosion-resistant metal material. A partition plate 2 is fixedly connected to the top inside, providing an installation base for components such as the energy storage component 6. Multiple storage boxes 3 are slidably connected inside the counter body 1, and multiple storage compartments 4 are snapped together on the inner wall of the cabinet door 11, providing a large storage space for items. Self-locking casters 5 are connected to the four corners at the bottom of the counter body 1 for easy movement and fixation.

[0071] Furthermore, this invention introduces an innovative energy storage component 6 design. This design, through the ingenious cooperation of the umbrella ribs 61, the rotating bead 65, and the first telescopic pump 68 and the second telescopic pump 69, allows the flexible solar panel 62 to flexibly adjust its angle and shape according to the sun's position, thereby maximizing solar energy absorption efficiency. This design breaks through the limitations of traditional outdoor sales counters in energy utilization. Simultaneously, this invention also integrates a condensing device 9 into the counter design. By installing condensing pipes 94 inside the backrest 91 and the rotating seat 92, and utilizing a condenser 93 for cooling, a cool and comfortable resting environment is provided for sales staff. This improvement is extremely rare in traditional outdoor sales counters, greatly enhancing the sales staff's working experience.

[0072] Furthermore, this invention combines the flexible solar panel 62 with the energy storage battery 8 (the energy storage battery 8 is installed inside the counter body 1, and the flexible solar panel 62 absorbs solar energy and converts it into electrical energy, which is stored inside the energy storage battery 8), thus constructing a complete outdoor self-sufficient energy system. This not only solves the power supply problem in outdoor sales but also effectively reduces sales costs, aligning with the concept of sustainable development.

[0073] Furthermore, by designing an intelligent adjustment mechanism, the first telescopic pump 68 and the second telescopic pump 69 are controlled by the adjustment key 10, which enables precise adjustment of the angle and shape of the flexible solar panel 62, improves energy utilization efficiency, and demonstrates the application potential of the technology in outdoor sales equipment.

[0074] Finally, the condensation technology was applied to the rest area of ​​the outdoor sales counter. Through the 94-cycle cooling of the condenser tube, the fatigue of sales staff in high-temperature environments was effectively alleviated, and work efficiency and sales quality were improved, demonstrating meticulous care for the work experience of sales staff.
