Description

Technical Field

[0001] This utility model relates to the field of emergency power supply technology, and more specifically, to a multi-purpose solar emergency power supply with an external battery. Background Technology

[0002] In outdoor operations, emergency rescue, and camping, emergency power supplies are crucial for ensuring power supply to equipment and basic lighting.

[0003] However, existing emergency power supplies have the following problems when in use:

[0004] Currently available emergency power supplies rely on external power sources for charging, making it difficult to replenish power in areas without grid coverage. Even those equipped with solar charging often suffer from low solar energy utilization due to their fixed support structure, which prevents flexible angle adjustments to adapt to different sunlight directions. Furthermore, most emergency power supplies are limited by their built-in battery capacity, rendering them unusable once depleted. They also lack easily removable external batteries for supplementation, resulting in limited functionality that only meets basic power needs, failing to address both lighting and simultaneous charging of multiple devices. Consequently, their practicality and adaptability in emergency scenarios are insufficient, failing to fully meet the diverse needs of users.

[0005] This utility model can efficiently acquire solar energy, flexibly adjust the support angle, and conveniently install and remove mobile batteries to supplement power supply. It can also be used for lighting and charging multiple devices, ensuring a stable energy supply in emergency scenarios and meeting diverse power needs. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a multi-purpose solar emergency power supply with an external battery.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-purpose solar emergency power supply with an external battery, comprising: an emergency power supply housing, a support strip rotatably connected to the surface of the emergency power supply housing, a movable battery embedded in the right side of the surface of the emergency power supply housing, a photovoltaic panel fixedly installed at the rear end of the emergency power supply housing, a limiting groove formed on the right side of the front of the emergency power supply housing, the movable battery being embedded inside the limiting groove and slidably connected to the limiting groove, a swivel groove formed at the bottom inside the limiting groove, and a connecting hole formed at the bottom inside the limiting groove.

[0008] A further preferred embodiment: A light is fixedly installed on the left side of the front of the emergency power supply housing. A functional area is provided below the light and the limiting groove. The functional area is provided with a power button, a brightness adjustment button, a USB charging port, and a TYPE-C port.

[0009] A further preferred embodiment: a fixing plate is fixedly installed at the middle of both the left and right ends of the emergency power supply housing, and a connecting rod is provided in the middle of the fixing plate.

[0010] A further preferred embodiment: the connecting rod is rotatably connected to the support bar, the inner side of the connecting rod is fixedly connected to the emergency power supply housing, and a plurality of limiting teeth are fixedly installed around the middle of the surface of the connecting rod, and the limiting teeth are fixedly connected to the fixing plate.

[0011] A further preferred embodiment: the support bar is U-shaped and its left and right ends are rotatably connected to the left and right ends of the emergency power supply housing. Rotation holes are provided at both ends of the support bar. Several limiting teeth are fixedly installed around the inner side of the rotation holes. The limiting teeth are matched with the limiting teeth.

[0012] A further preferred embodiment: the bottom center of the mobile battery has an alignment groove, which is matched with the connection hole. A terminal is fixedly installed inside the alignment groove, and the terminal is electrically connected to the connection hole.

[0013] A further preferred embodiment: a power switch is fixedly installed on the left side of the alignment slot, a charging port is provided on the front side of the alignment slot, and a power indicator light is fixedly installed on the right side of the alignment slot.

[0014] Beneficial effects:

[0015] 1. Equipped with photovoltaic panels and a portable battery, the photovoltaic panels convert solar energy into electrical energy to charge the internal battery of the emergency power supply. It does not rely on an external power source and can continuously obtain energy in outdoor or power outage scenarios where power supply is lacking, ensuring the basic power supply capability of the emergency power supply. When paired with the portable battery, the two can work flexibly: when the emergency power supply is out of power, the portable battery can charge it; and the portable battery can be removed and used as an independent power bank. It also has multiple interfaces, power display, and switch functions, further improving the flexibility and practicality of power supply and meeting the diverse power needs in different scenarios.

[0016] 2. By incorporating limiting slots, guide slots, alignment slots, and terminals, the limiting slots provide precise positioning and guidance for the portable battery, ensuring smooth insertion and stable installation, preventing displacement during use. The guide slots facilitate manual operation, allowing for easy removal and installation of the portable battery, enhancing usability. The matching alignment slots and terminals enable the portable battery to quickly and accurately align with the connection holes within the limiting slots, ensuring the stability of the electrical connection and guaranteeing that the portable battery can reliably replenish or power emergency power supplies. These structures work together to improve the stability of the portable battery and emergency power supply, simplify the operation process, and allow users to efficiently utilize the power function in emergency scenarios.

[0017] 3. By setting up a limiting tooth one, a support bar, and a limiting tooth two, the support bar is U-shaped and rotatably connected to the housing. With the limiting tooth one on the connecting rod and the limiting tooth two in the rotation hole of the support bar, when the angle of the support bar is manually adjusted, the two limiting teeth can precisely engage. When the adjustment stops, the support bar can stay stably in the current position, which not only prevents the housing from shaking, but also allows for flexible adjustment to the optimal angle for the photovoltaic panel to receive sunlight, improving solar charging efficiency. At the same time, the stable support also makes it convenient for users to operate the function area buttons and check the status of the mobile battery, further optimizing the user experience.

[0018] 4. In summary, this multi-purpose solar emergency power supply with an external battery achieves efficient synergy between function and practicality through its structure, which includes a photovoltaic panel, a limiting groove, a locating groove, a first limiting tooth, a support bar, a second limiting tooth, a movable battery, an alignment groove, and terminals. The photovoltaic panel provides a clean solar charging path for the device. Combined with the support bar, the first limiting tooth, and the second limiting tooth, the angle of the housing can be flexibly adjusted and securely fixed, ensuring that the photovoltaic panel is always in the optimal position to receive sunlight, thus improving charging efficiency. The limiting groove, locating groove, alignment groove, and terminals provide a convenient and stable installation and electrical connection structure for the movable battery. This facilitates quick assembly and disassembly of the movable battery from the housing while ensuring reliable power transmission for both. The movable battery can serve as an emergency power supplement, further expanding the device's power supply scenarios and endurance. The overall structural design balances energy acquisition, ease of operation, and power supply reliability, fully meeting the diverse usage needs in emergency scenarios. Attached Figure Description
