[0033] In existing technologies, in cold regions, low temperatures significantly reduce the charging and discharging performance of batteries, leading to a substantial decrease in power supply efficiency and affecting the lifespan of the power supply. Currently, there are methods to heat batteries by setting up heating components to improve the stability of battery charging and discharging. However, continuous heating increases energy consumption, and excessive heat can also affect battery functionality. Furthermore, during power supply, excessively low battery temperatures can also affect the power supply function.

[0034] This utility model provides an outdoor power supply device for use in cold regions, such as... Figure 1 and Figure 2 As shown, in this embodiment, the outdoor power supply device includes a housing 4 and a first power component 1, a second power component 2, a third power component 3, an adapter plate 5, and a heating component disposed inside the housing 4. The first power component 1 serves as the main power supply, the second power component serves as the backup power supply, and the third power component 3 serves as the power supply for the heating component. By using the third power component 3 to supply power to the heating component independently, the stability of the power supply to the heating component can be guaranteed, and it is not affected by the first power component 1 and the second power component 2. When the first power component 1 runs out of power or malfunctions, the second power component 2 provides power and is used as a temporary functional unit.

[0035] The first power supply component 1 and the second power supply component 2 are connected to the adapter plate 5, and the third power supply component 3 is connected to the first power supply component 1 and the heating component. The adapter plate 5 is connected to the terminal block for external devices to connect and supply power. The third power supply component 3 is connected to the heating component to supply power to the heating component. The third power supply component 3 is charged by the first power supply component 1 to supply power to the heating component. It should be noted that the third power supply component 3 is charged when the first power supply component 1 is not powered, and the third power supply component 3 does not charge when the first power supply component 1 is powered, so as to avoid affecting the power supply efficiency of the first power supply component 1.

[0036] To ensure power supply stability, both the first power assembly 1 and the second power assembly 2 are equipped with temperature sensors. The heating components include a first heating element 6 and a second heating element 7. The first heating element 6 is attached to the first power assembly 1 to heat it, and the second heating element 7 is attached to the second power assembly 2 to heat it. The heating elements are made of nickel-chromium alloy to ensure the battery maintains a suitable operating temperature range in low-temperature environments. The heating element power is 50-100 watts. The first heating element 6 and the second heating element 7 are individually controlled, allowing them to heat the first power assembly 1 and the second power assembly 2 independently. A control switch is also included to control the on / off state of the first heating element 6 and the second heating element 7. The temperature sensors detect the temperature of the first power assembly 1 and the second power assembly 2. When the temperature of a power assembly is low, the corresponding heating element is activated to ensure its normal function. This invention can operate normally at -40 degrees Celsius. When the detected temperature of a power assembly is below -20 degrees Celsius, the heating element is automatically activated. Heating stops when the temperature reaches 0 degrees Celsius to avoid energy waste and disruption to the normal power supply.

[0037] To improve the strength and thermal insulation of the casing 4, such as Figure 3 As shown, the housing 4 includes a metal outer shell 41 and a heat-insulating inner shell 42, with the heat-insulating inner shell 42 located inside the metal outer shell 41. The metal outer shell 41 is composed of high-strength metal, possessing strong impact resistance and cold resistance. The heat-insulating inner shell 42 is made of a high-strength composite material with low thermal conductivity; in this embodiment, polyimide foam material is used. The heat-insulating inner layer effectively reduces the rate of heat loss from the interior to the exterior, creating a relatively stable thermal environment for internal components such as batteries. This greatly reduces the impact of external cold environments on the internal temperature of the power supply device, ensuring that the battery and other key components can maintain a good operating temperature range under extremely cold conditions, thereby ensuring the overall performance stability of the power supply device. The metal outer shell 41, made of aluminum alloy, gives the power supply device excellent mechanical strength and weather resistance, enabling it to withstand various impacts, vibrations, and possible physical damage in harsh outdoor environments. This provides a reliable protective barrier for internal precision components, extends the service life of the power supply device, and reduces the risk of failure due to external physical factors.

[0038] To further improve the structural strength of the shell 4, a reinforcing column 43 is provided between the metal outer shell 41 and the heat-insulating inner shell 42. The two ends of the reinforcing column 43 abut against the metal outer shell 41 and the heat-insulating inner shell 42 respectively. The reinforcing column 43 is set as a frustum structure for stable support. In this embodiment, a metal layer is provided on the side of the heat-insulating inner shell 42 facing the reinforcing column 43. The metal layer is connected to the reinforcing column 43 to prevent the reinforcing column 43 from damaging the heat-insulating inner shell 42 and affecting the heat insulation effect when the outer shell is impacted.

[0039] To ensure uniform temperature distribution within the power supply assembly and improve functional stability, the first power supply assembly 1 includes multiple electrically connected battery modules. These modules are connected by thermally conductive silicone pads with a thickness of 0.5-1 mm and a thermal conductivity of 2-5 W / (m·K). These pads uniformly transfer heat during battery operation, preventing localized overheating or underheating. In this embodiment, a temperature sensor is provided on one side of each battery module to detect the temperature of each module and determine if there is any instability in power supply. In other embodiments, a heating element can be provided on each battery module for individual heating. The batteries are capacitor batteries, which exhibit good discharge performance at low temperatures, high charging efficiency, and good stability.

[0040] To ensure the stability of the first power supply assembly 1 and the second power supply assembly 2 within the housing 4; such as Figure 3 and Figure 4 As shown, a fixing plate 8 is also provided inside the housing 4. The fixing plate 8 is located at the upper end of the first power supply assembly 1 and the second power supply assembly 2. The two ends of the fixing plate 8 are against the inner walls of the housing 4, the top of the fixing plate 8 is against the inner top wall of the housing 4, and the bottom of the housing 4 is against the first power supply assembly 1 and the second power supply assembly 2. The first power supply assembly 1 and the second power supply assembly 2 are fixed inside the housing 4, which improves the stability of the movement of the first power supply assembly 1 and the second power supply assembly 2 and prevents the power supply equipment from shaking when moving.

[0041] To ensure uniform and rapid heating of the power components, both the first heating element 6 and the second heating element 7 include a main heating element and an auxiliary heating element. The main heating element is located on the inner wall of the housing 4, specifically on the inner bottom wall and inner side wall of the housing 4. The auxiliary heating element is located at the bottom of the fixing plate 8 and contacts the first power component 1 and the second power component 2. During heating, the main heating element and the auxiliary heating element are activated simultaneously to heat the power components synchronously from multiple directions, thereby improving the uniformity and speed of heating.

[0042] To improve the stability of the adapter plate 5 during installation, the adapter plate 5 is vertically installed inside the housing 4 between the first power supply assembly 1 and the second power supply assembly 2. A limiting groove 81 is provided at the bottom of the fixing plate 8. The bottom of the adapter plate 5 abuts against the inner bottom wall of the housing 4, and the top end is inserted into the limiting groove 81 of the fixing plate 8 to limit and fix the adapter plate 5.

[0043] To improve practicality and convenience, the second power assembly 2 is designed to be removable and usable. Like the first power assembly 1, the second power assembly 2 has a charging connection area, which includes at least one Type-A and one Type-C interface; specifically, as shown... Figure 3 and Figure 5As shown, the second power supply assembly 2 is detachably installed inside the housing 4. One end of the housing 4 has a mounting slot for inserting the second power supply assembly 2. The slot opening is provided with an openable and closable door 9. When closed, the door 9 can prevent the second power supply assembly 2 from detaching from the housing 4. The door 9 can be a telescopic folding door, a hinged sliding door, or a sliding door that can slide on the housing 4. The closed door 9 prevents the second power supply assembly from detaching from the housing 4. The second power supply assembly 2 is provided with a first connecting part 10, and the adapter plate 5 faces the second power supply assembly 2. A second connecting part 11 is provided on one side of the second power assembly 2. When the second power assembly 2 is inserted into the mounting slot, the first connecting part 10 and the second connecting part 11 are electrically connected. The abutting electrical connection of the first connecting part 10 and the second connecting part 11 is the prior art, such as the first connecting part 10 being a pogopin connector and the second connecting part 11 being a corresponding contact. The first connecting part 10 is located on the side of the second power assembly 2 near the adapter plate 5. In order to facilitate the insertion and removal of the second power assembly 2, a handle is provided at the end of the second power assembly 2 away from the first connecting part 10 for easy pulling and removal.

[0044] To remind users, a first indicator light 12 and a second indicator light 13 are provided on the outside of the housing 4. The first indicator light 12 lights up when the first power component 1 is powered, and the second indicator light 13 lights up when the second power component 2 is powered, which can remind users of the usage status of the power equipment and charge the power components in time. A lifting part 14 is provided at the upper end of the housing 4 to facilitate carrying the portable power equipment.

[0045] This invention uses a temperature sensor to measure the temperature of the power supply component, enabling precise control of the heating process and preventing the power supply from being affected by excessively low temperatures. It also allows for timely shutdown of heating when the temperature is high, improving the stability of the outdoor power supply in cold regions. The independently configured third power supply component 3 controls the heating element, ensuring heating stability. Furthermore, the second power supply component 2 is used as a backup power source and is designed with a detachable structure, enhancing the functionality and power supply stability of the outdoor power supply.
