In order to drive high-power electrical appliances, outdoor power supply is usually equipped with an inverter. In the traditional technology, the inverter and the battery assembly of the outdoor power supply are usually installed on the same circuit board, and a protective shell is arranged on the outer cover. Considering the heat dissipation and ventilation and the mutual influence between the circuit assemblies during work, the volume of the outdoor power supply is usually large, which is inconvenient to carry. Moreover, the outdoor power supply is often damaged by impact during outdoor use. SUMMARY

The panel frame is installed on the lower shell and flush with the outer peripheral wall of the lower shell. The cover, the panel frame and the lower shell form a containing space for accommodating the inverter module, the power management module and the battery assembly.

[0005] The battery assembly is installed on the bottom wall of the lower shell. The power management module is installed on the side of the battery assembly away from the bottom wall and is used to control the power supply state of the battery assembly. The power management module is electrically connected to the battery assembly. The inverter module is installed on the housing of the battery assembly and is stacked with the battery assembly. The inverter module is communicatively connected to the power management module. The panel frame is electrically connected to the inverter module. The panel frame is communicatively connected to the power management module.

[0092] In traditional technology, outdoor power supplies typically mount the inverter and battery pack on the same circuit board and are covered by a protective shell. Considering heat dissipation, ventilation, and the mutual influence between circuit components during operation, outdoor power supplies are usually large in size and inconvenient to carry. Moreover, outdoor power supplies are often damaged by impacts during outdoor use.

[0093] Therefore, it is necessary to provide an outdoor energy storage device 100.

[0094] Please see Figure 1 , Figure 2 and Figure 26 , Figure 1 This is a schematic diagram of the structure of an outdoor energy storage device 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the assembly structure of the cover 10 and the lower shell 20. Figure 26 This is a schematic diagram of the power supply module in one embodiment of the present invention.

[0095] An outdoor energy storage device 100 is characterized in that it includes a cover 10, a lower shell 20, a panel frame 30, an inverter module 61, a power management module 62, and a battery assembly 70. The cover 10 covers the lower shell 20, and the panel frame 30 is installed on the lower shell 20 and flush with the outer peripheral wall of the lower shell 20. The cover 10, the panel frame 30, and the lower shell 20 form an accommodating space 103, which is used to accommodate the inverter module 61, the power management module 62, and the battery assembly 70.

[0096] The battery pack 70 is mounted on the bottom wall 214 of the lower housing 20. The power management module 62 is mounted on the side of the battery pack 70 that is relatively far from the bottom wall 214 and is used to adjust the power supply of the battery pack 70. The power management module 62 is electrically connected to the battery pack 70. The inverter module 61 is mounted on the housing 101 of the battery pack 70 and is stacked with the battery pack 70. The inverter module 61 is communicatively connected to the power management module 62. The panel frame 30 is electrically connected to the inverter module 61 and is communicatively connected to the power management module 62.

[0097] In this way, the battery assembly 70 is mounted on the side wall of the lower shell 20, the inverter module 61 is mounted on the battery assembly 70, the cover 10 covers the lower shell 20, and the battery assembly 70 and the inverter module 61 are fixedly connected with the cover 10 and the lower shell 20. In actual use, the relative position between the inverter module 61 and the battery assembly 70 is fixed and not easy to shake, thereby ensuring stable power supply. In addition, the battery assembly 70 is also electrically connected with the power management module 62, and the power management module 62 is used for controlling the power supply state of the battery assembly 70, thereby further ensuring the safety of power supply and avoiding over-discharge of the battery assembly 70, and prolonging the service life of the battery assembly 70. The panel frame 30, the cover 10 and the lower shell 20 form the accommodation space 103, so that the panel frame 30, the cover 10 and the lower shell 20 jointly form the shell 101 of the outdoor energy storage device, and the panel frame 30 is also in communication connection with the power management module 62, thereby reducing the occupation of the panel frame 30 to the internal space of the outdoor energy storage device 100, so that the volume of the outdoor energy storage device 100 is smaller and the portability is higher.

[0098] In order to facilitate carrying, a handle is usually arranged on the shell of the outdoor energy storage device. In the traditional technology, the handle is usually connected with the shell as a separate structure. The connection between the handle and the shell needs to bear the load of the entire outdoor energy storage device, and damage often occurs in actual use. Based on this, it is necessary to design a shell of an outdoor energy storage device.

[0101] This design, through the gripping space 102 formed by the first handle 12, the second handle 22, and the support 11, facilitates direct gripping and handling by the user, resulting in greater portability and reduced effort during transport, thus improving transport efficiency. The one-to-one correspondence between the first handle 12 and the second handle 22, and the corresponding correspondence between the housing 21 and the support 11, minimizes the deformation difference between the first handle 12 and the second handle 22 under stress, helping to prevent cracking of the surface of the outdoor energy storage device 100 due to deformation and misalignment of the first handle 12 and the second handle 22.

[0173] Outdoor energy storage devices are suitable for high-power electrical appliances. In actual use, inverter modules and battery packs easily generate a large amount of heat. Due to the obstruction of the casing, heat accumulation easily occurs inside the outdoor energy storage device, affecting the lifespan of the battery packs. Traditional technology uses fans to dissipate heat from the outdoor energy storage device. The fan is placed at the heat source, guiding cool air directly to the heat source and carrying away the heat. This cooling method only considers the cooling of the main heat source. However, outdoor energy storage devices also contain other circuit components, which are prone to heat accumulation over long-term use. In addition, cool air can easily diffuse to other circuit components after passing through the heat source, transferring heat from the heat source to other circuit components, exacerbating heat accumulation and hindering the overall heat dissipation of the outdoor energy storage device. Therefore, it is necessary to provide a heat dissipation component that works in conjunction with outdoor energy storage devices.

The cold air flow can pass through the inverter module 61 along the first air duct 1041, avoiding the cold air flow from being dissipated when passing through the inverter module 61, which is conducive to reducing the dissipation of the cold air flow in the heat dissipation path and improving the heat dissipation efficiency. The first heat dissipation port 241 and the second heat dissipation port 242 are arranged at two ends of the first air duct 1041 and the gap 104, facilitating the cold air flow to directly enter the first air duct 1041 and the gap 104, which is conducive to reducing the air circulation loss and improving the heat dissipation efficiency.

[0185] In this way, the first mounting column 631 can not only reduce heat transfer between the power management module 62 and the battery assembly 70, but also has less resistance to the cold air flow when the cold air flow passes through the second air duct 1042, thereby increasing the flow rate of the cold air flow and improving the heat dissipation effect of the outdoor energy storage device 100.
