Description

Technical Field

[0001] This application relates to the field of power storage and mobile power technology, and in particular to an outdoor mobile power supply. Background Technology

[0002] Outdoor portable power banks are mobile, portable, and high-capacity energy storage devices. They are generally equipped with high-capacity lithium-ion batteries that can store a large amount of electrical energy. They have a variety of output interfaces, such as common AC power interfaces and USB interfaces, and can be used with various electronic devices such as mobile phones, tablets, cameras, and drones. Early portable power banks mostly used lead-acid batteries. Although they were low in cost, their low energy density resulted in large size and heavy weight. For example, a 200Wh capacity product was about the size of a small suitcase and weighed about 15kg. Moreover, charging took 8-10 hours, resulting in poor portability and emergency charging capabilities. Although nickel-metal hydride batteries have improved in terms of environmental friendliness, they have a high self-discharge rate. After being idle for a month, the power loss exceeds 50%, and the cycle life is only 500-800 cycles. Frequent replacements increase costs.

[0003] On the production line of outdoor portable power banks with detachable batteries, the casing installation process is becoming a major challenge restricting production efficiency and product quality. Existing casing designs mostly adopt a three-layer cavity structure, requiring extremely high precision in the fit of each component. Workers must accurately align multiple points in a confined space; even slight deviations can prevent successful assembly. This is not only time-consuming and labor-intensive but also easily causes problems such as internal circuit compression, resulting in stagnant installation efficiency, severely slowing down the overall production pace, hindering capacity expansion, and placing dual pressures on companies regarding cost control and delivery cycles. Summary of the Invention

[0004] In order to overcome the shortcomings of the complex installation of the shell of the outdoor portable power bank with detachable battery in the prior art, this application provides an outdoor portable power bank that can achieve the advantages of convenient shell installation and simple manufacturing.

[0005] To achieve the above objectives, this application adopts the following technical solution: an outdoor portable power bank, comprising a housing, the housing including a body and a cover and a bottom detachably connected to the body, the body including a body body and a back panel, the body body having an opening on the rear side, the back panel being installed on the rear side of the body body and closing the opening, the cover being connected to the body body by fasteners, the bottom being connected to the body body by fasteners, the housing having a vertically spaced front partition and a rear partition, the front partition and the rear partition dividing the space inside the housing into a first electrical installation cavity, a battery installation cavity and a second electrical installation cavity arranged sequentially from front to back, the front partition being connected to at least one of the body, the cover and the bottom by fasteners, and the rear partition being connected to at least one of the body, the cover and the bottom by fasteners.

[0006] After adopting the above technical solution, this application has the following advantages: Since the rear side of the housing body has an opening, the internal electrical components can be completely enclosed by expanding the housing body outwards. Therefore, the outdoor portable power bank can first assemble the three-layer cavity structure before the exterior, and then fit the housing body over the internal components. When encountering areas with small gaps, the housing body can be expanded outwards to increase the internal width, facilitating the smooth enclosure of all internal components. Specifically, the internal components can be divided into three layers by the front and rear partitions. Then, the corresponding electrical components are installed in the first and second electrical mounting cavities, and the corresponding components are connected accordingly. This structure allows for faster assembly of internal components, significantly increasing the overall assembly speed. Because this type of structure is simpler to install, it reduces the occurrence of scratches on the outer shell and compression of internal wiring caused by improper installation (such as deviations leading to assembly failure), thereby reducing the defect rate, improving product quality, and lowering the manufacturing requirements and costs of structural components such as the housing body.

[0007] Furthermore, the top of the rear partition is bent to form an upper connecting part, and the chassis cover is fixed to the upper connecting part by fasteners; and / or, the bottom of the rear partition is bent to form a lower connecting part, and the chassis bottom is fixed to the lower connecting part by fasteners.

[0008] Using the aforementioned technical solution, the rear partition is fixed to the chassis cover via the upper connecting part at the top and to the chassis bottom via the lower connecting part at the bottom. This connection method makes the connection between the rear partition and the chassis cover and chassis bottom tighter and more stable. The upper and lower connecting parts formed by bending provide a clear positioning structure for the installation of the chassis cover and chassis bottom. During installation, workers can more easily and accurately place the chassis cover and chassis bottom in the corresponding positions and then fix them with fasteners, reducing the adjustment and alignment time during installation and improving installation efficiency. This design makes the connection between the rear partition and the chassis cover and chassis bottom more standardized and modular, facilitating manufacturing and assembly, thus further reducing production costs and improving production efficiency and product quality.

[0009] Furthermore, the top of the front partition is bent forward to form an upper connecting part, which covers the top of the first electrical appliance mounting cavity and is fixed to the chassis body by fasteners, and / or the bottom of the front partition is bent to form a lower connecting part, which is fixed to the chassis bottom by fasteners.

[0010] Using the aforementioned technical solution, the upper connecting part at the top of the front partition is fixed to the main body of the enclosure, and the lower connecting part at the bottom is fixed to the bottom of the enclosure, thus forming a stable connection between the upper and lower parts of the front partition and the enclosure. This effectively reduces the relative displacement between the front partition and other parts of the enclosure, thereby reducing the risk of damage to internal components due to shaking or collision, and extending the service life of the power bank. The upper connecting part shields the top of the first electrical mounting cavity, providing additional protection for the electrical components inside. This prevents dust, debris, etc., from falling into the mounting cavity from above, reducing electrical malfunctions caused by foreign objects entering and improving product reliability.

[0011] Furthermore, the left end of the front partition is abutted against the left side wall of the box body, and the right end of the front partition is abutted against the right side wall of the box body; and / or, the left end of the rear partition is abutted against the left side wall of the box body, and the right end of the rear partition is abutted against the right side wall of the box body.

[0012] Using the aforementioned technical solution, the front and rear partitions are firmly abutted against the left and right side walls of the main body, creating a tight fit between the partitions and the main body. This tight connection effectively enhances the overall structural strength of the outdoor power bank, reducing component loosening or displacement caused by vibration, collisions, or other external forces during transportation or use, thereby improving product reliability and durability. This abutting design provides a clear positioning reference for the installation process. During assembly, workers can more easily and accurately install the front and rear partitions into their appropriate positions within the main body, reducing adjustment and calibration time and improving installation efficiency.

[0013] Furthermore, the box body is integrally bent from a single sheet metal piece.

[0014] Using the aforementioned technical solution, the one-piece bent body has no seams, resulting in better overall strength and rigidity compared to structures assembled from multiple panels. When subjected to external impacts, compression, or vibration, the one-piece bent body can more effectively distribute stress, reducing the risk of damage caused by stress concentration at seams. This improves the overall structural stability of the outdoor power bank and ensures the safety of internal electrical components and batteries. Furthermore, the one-piece bent design allows for better recovery and deformation when the body expands outwards, making installation easier and enhancing the overall integrity of the enclosure.

[0015] Furthermore, a power socket and a display are installed on the front side of the enclosure, and the power socket and display components are located in the first electrical installation cavity.

[0016] By adopting the aforementioned technical solution, the power socket and part of the display structure are located within the first electrical installation cavity. This fully utilizes the internal space of the enclosure, allowing for a rational distribution of the power socket, display, and other electrical components, avoiding spatial conflicts between parts. This enables the integration of more functional components within a limited enclosure space, enhancing the functionality and practicality of the outdoor power bank while ensuring a compact and orderly internal structure.

[0017] Furthermore, an inverter is installed inside the second electrical installation cavity, and the inverter is mounted to the rear partition by fasteners.

[0018] By adopting the aforementioned technical solution, the inverter is installed in the second electrical mounting cavity, making full use of the internal space layout of the enclosure. This allows the inverter to be rationally distributed with other components (such as batteries and components in the first electrical mounting cavity) without interference. Within the limited space of the outdoor portable power bank enclosure, functional components are effectively integrated, improving space utilization and ensuring the compactness of the overall structure. Fixing the inverter to the rear partition creates a stable connection between the inverter and the enclosure structure. As one of the important supporting structures inside the enclosure, the rear partition effectively bears the weight of the inverter and external forces such as vibrations generated during operation, reducing the inverter's shaking and displacement during use. This enhances the overall stability of the outdoor portable power bank structure, ensures the normal operation of internal components, and extends the product's lifespan.

[0019] Furthermore, the bottom of the battery mounting cavity is fixed with a front-to-back extending wire groove baffle by fasteners. The wire groove baffle is provided with a wire passage groove, and the front and rear ends of the wire passage groove are respectively connected to the first electrical appliance mounting cavity and the second electrical appliance mounting cavity.

[0020] By adopting the aforementioned technical solution, the cable tray baffle and cable tray configuration provide a clear routing channel for the internal wiring of the power supply. This allows the wiring from the first electrical mounting cavity to the second electrical mounting cavity to be neatly arranged within the cable tray, avoiding messy tangling and effectively managing the internal wiring layout of the power supply, making the entire wiring system more organized and orderly. This cable tray baffle and cable tray design provides a standardized wiring layout scheme for power supply production. During mass production, the wiring layout is identical for each power supply product, facilitating production management and quality control, and ensuring the consistency and stability of product quality.

[0027] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] like Figures 1 to 2As shown, this application provides an outdoor portable power bank, including a housing 1. The housing 1 includes a body 11 and a cover 12 and a bottom 13 detachably connected to the body 11. The body 11 includes a main body 111 and a back panel 112. The main body 111 has an opening on its rear side. The back panel 112 is installed on the rear side of the main body 111 and closes the opening on the rear side of the main body 111. The cover 12 is connected to the main body 111 by fasteners, and the bottom 13 is connected by fasteners. The fastener is connected to the housing body 111. The housing body 1 is provided with a front partition 2 and a rear partition 3 arranged vertically at intervals. The front partition 2 and the rear partition 3 divide the space inside the housing body 1 into a first electrical installation cavity 14, a battery installation cavity 15 and a second electrical installation cavity 16 arranged in sequence. The front partition 2 is connected to at least one of the housing body 11, the chassis cover 12 and the chassis bottom 13 by fasteners. The rear partition 3 is connected to at least one of the housing body 11, the chassis cover 12 and the chassis bottom 13 by fasteners.

[0029] After adopting the above technical solution, this application has the following advantages: Since the rear side of the housing body 111 is provided with an opening, the internal electrical components can be fully wrapped by expanding the housing body 11 outward. Therefore, the outdoor mobile power supply can first assemble the three-layer cavity structure before the outside, and then put the housing body 111 on top of the internal components. When encountering a small gap, the housing body 111 can be expanded outward to increase the width inside the housing body 11, so as to smoothly wrap all the internal components inside the housing body 11. Specifically, the internal components can be divided into three layers by the front partition 2 and the rear partition 3. Then, the corresponding electrical components are installed in the first electrical mounting cavity 14 and the second electrical mounting cavity 16, and the corresponding components are connected accordingly. This structure can make the assembly speed of the internal components faster, and the assembly speed of the whole machine can be increased rapidly. Because this type of structure is easier to install, it reduces the occurrence of problems such as scratches on the outer shell and compression of internal circuits caused by improper installation (such as deviations that prevent smooth assembly), thereby reducing the defect rate, improving product quality, and also reducing the manufacturing requirements of structural components such as the enclosure 11, thus reducing the manufacturing cost of these parts.

[0030] Preferably, the chassis cover 12 is fixedly connected to the chassis body 111 by fasteners, the chassis bottom 13 is fixedly connected to the chassis body 111 by fasteners, the front partition 2 is fixedly connected to the chassis body 11, the chassis cover 12 and the chassis bottom 13 by fasteners respectively, and the rear partition 3 is fixedly connected to the chassis body 11, the chassis cover 12 and the chassis bottom 13 by fasteners respectively; the fasteners are bolts and other parts.

[0031] Furthermore, the top of the rear partition 3 is bent to form an upper connecting part 4, and the chassis cover 12 is fixed to the upper connecting part 4 by fasteners; and / or, the bottom of the rear partition 3 is bent to form a lower connecting part 5, and the chassis bottom 13 is fixed to the lower connecting part 5 by fasteners.

[0032] Using the aforementioned technical solution, the rear partition 3 is fixed to the chassis cover 12 via the upper connecting part 4 at the top, and fixed to the chassis bottom 13 via the lower connecting part 5 at the bottom. This connection method makes the connection between the rear partition 3 and the chassis cover 12 and chassis bottom 13 tighter and more stable. The upper connecting part 4 and lower connecting part 5, formed by bending, provide a clear positioning structure for the installation of the chassis cover 12 and chassis bottom 13. During installation, workers can more easily and accurately place the chassis cover 12 and chassis bottom 13 in the corresponding positions, and then fix them with fasteners, reducing the adjustment and alignment time during installation and improving installation efficiency. This design makes the connection between the rear partition 3 and the chassis cover 12 and chassis bottom 13 more standardized and modular, facilitating manufacturing and assembly, thus further reducing production costs and improving production efficiency and product quality.

[0033] Furthermore, the top of the front partition 2 is bent forward to form an upper connecting part 4, which covers the top of the first electrical appliance mounting cavity 14 and is fixed to the housing body 111 by fasteners, and / or the bottom of the front partition 2 is bent to form a lower connecting part 5, which is fixed to the bottom of the housing by fasteners.

[0034] Using the aforementioned technical solution, the upper connecting part 4 at the top of the front partition 2 is fixed to the main body 111, and the lower connecting part 5 at the bottom is fixed to the bottom of the chassis 13, thus forming a stable connection between the upper and lower parts of the front partition 2 and the chassis 1. This effectively reduces the relative displacement between the front partition 2 and other parts of the chassis 1, thereby reducing the risk of damage to internal parts due to shaking or collision and extending the service life of the power bank. The upper connecting part 4 shields the top of the first electrical mounting cavity 14, providing additional protection for the electrical components inside the cavity. This prevents dust, debris, etc., from falling into the mounting cavity from above, reducing electrical malfunctions caused by foreign objects entering and improving product reliability.

[0035] Furthermore, the left end of the front partition 2 abuts against the left side wall of the box body 111, and the right end of the front partition 2 abuts against the right side wall of the box body 111; and / or, the left end of the rear partition 3 abuts against the left side wall of the box body 111, and the right end of the rear partition 3 abuts against the right side wall of the box body 111.

[0036] Using the aforementioned technical solution, the front partition 2 and the rear partition 3 are respectively abutted against the left and right side walls of the housing body 111, forming a tight fit between the partitions and the housing body 111. This tight connection effectively enhances the overall structural strength of the outdoor power bank, reducing component loosening or displacement caused by external forces such as vibration and collision during transportation or use, thereby improving product reliability and durability. This abutting design provides a clear positioning reference for the installation process. During assembly, workers can more easily and accurately install the front partition 2 and the rear partition 3 into the appropriate positions within the housing body 11, reducing adjustment and calibration time during installation and improving installation efficiency.

[0037] Furthermore, the box body 111 is integrally bent from a plate.

[0038] Using the aforementioned technical solution, the one-piece bent housing 111 has no seams, resulting in better overall strength and rigidity compared to structures composed of multiple panels. When subjected to external impacts, compression, or vibrations, the one-piece bent housing 111 can more effectively disperse stress, reducing the risk of damage caused by stress concentration at seams. This improves the overall structural stability of the outdoor power bank and ensures the safety of internal electrical components and batteries. Furthermore, the one-piece bent design allows the housing 1 to have better recovery performance and deformation when expanding outwards, making overall installation of the housing 1 more convenient and enhancing its overall integrity.

[0039] Furthermore, a power socket 17 and a display 18 are installed on the front side of the housing 11, and the power socket 17 and the display 18 are partially located in the first electrical installation cavity 14.

[0040] By adopting the aforementioned technical solution, the power socket 17 and part of the display 18 are housed within the first electrical installation cavity 14. This fully utilizes the internal space of the housing 1, allowing for a rational distribution of the power socket 17, display 18, and other electrical components, thus avoiding spatial conflicts between parts. This enables the integration of more functional components within the limited space of the housing 1, enhancing the functionality and practicality of the outdoor power bank while ensuring a compact and orderly internal structure.

[0041] Furthermore, an inverter 19 is installed in the second electrical installation cavity 16, and the inverter 19 is installed on the rear partition 3 by fasteners.

[0042] By adopting the aforementioned technical solution, the inverter 19 is installed inside the second electrical mounting cavity 16, making full use of the internal space layout of the enclosure 1. This allows the inverter 19 to be rationally distributed with other components (such as the battery and components in the first electrical mounting cavity 14) without interference. Within the limited space of the outdoor power bank enclosure 1, functional components are effectively integrated, improving space utilization and ensuring the compactness of the overall structure. The inverter 19 is fixed to the rear partition 3, forming a stable connection between the inverter 19 and the enclosure 1 structure. As one of the important supporting structures inside the enclosure 1, the rear partition 3 effectively bears the weight of the inverter 19 and external forces such as vibrations generated during operation, reducing the shaking and displacement of the inverter 19 during use. This enhances the overall stability of the outdoor power bank structure, ensures the normal operation of internal components, and extends the product's service life.

[0043] Furthermore, the bottom of the battery mounting cavity 15 is fixed with a front-to-back extending wire groove baffle 6 by fasteners. The wire groove baffle 6 is provided with a wire passage groove 61, and the front and rear ends of the wire passage groove 61 are respectively connected to the first electrical appliance mounting cavity 14 and the second electrical appliance mounting cavity 16.

[0044] By adopting the aforementioned technical solution, the cable tray baffle 6 and the cable tray 61 provide a clear routing channel for the internal wiring of the power supply. This allows the wiring from the first electrical mounting cavity 14 to the second electrical mounting cavity 16 to be neatly arranged within the cable tray 61, avoiding messy tangling and effectively managing the internal wiring layout of the power supply, making the entire wiring system more orderly and organized. This design of the cable tray baffle 6 and the cable tray 61 provides a standardized wiring layout scheme for power supply production. During mass production, the wiring layout is identical for each power supply product, facilitating production management and quality control, and ensuring the consistency and stability of product quality.
