[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] like Figures 1 to 8 As shown, the portable energy storage power station of the present invention mainly includes a battery 6, an inverter 401, a controller 5, a housing 1, an output panel 8 and a charging input panel 9, etc. The inverter 401 can convert the direct current of the battery 6 into alternating current and output it from the output panel 8. Of course, DC output interfaces of various voltages can also be configured on the output panel 8. The controller 5 controls all AC / DC outputs and has output protection functions such as overload, overcurrent, undervoltage and short circuit. A charging input panel 9 is also provided on the housing 1, and the battery 6 can be charged from the mains, solar energy or generator through the charging input panel 9. The controller 5 can control the entire charging process and has charging protection functions such as overcharge, overvoltage and overcurrent. A high-current contactor is also provided in the power station. When an abnormality such as overload or short circuit occurs at the charging or output port, the controller 5 will disconnect the contactor, thereby cutting off the battery input and output to protect the power station or electrical appliances.

[0029] like Figure 8 As shown, the housing 1 of this embodiment is mainly composed of a left housing 101, a right housing 102, a front panel 103, a rear panel 104, a handle cover 105 and a base 106. The housing 1 and its components are usually made of metal or plastic, and a handle device 3 is provided on the top of the housing. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the basic outline of the portable energy storage power station is designed to occupy a rectangular space. The outer contour of its housing 1 is an approximate rectangular shape with a length L1, a width W1 and a height H1, and its length L1 ≥ width W1. When the energy storage power station is placed vertically, that is, when the surface where the handle device 3 is located is the top surface and the surface where the base 106 is located is the bottom surface, the vertical height of the power station at this time is the height H1. An output panel 8 is arranged on the surface formed by the width W1 and the height H1 at one end of the power station, specifically arranged above the front panel 103 at the front of the housing 1, and multiple AC and DC output interfaces are arranged on the output panel 8. A housing air inlet 1031 is arranged below the output panel 8, specifically located below the housing front panel 103. A controller 5 is arranged in the housing 1, and the controller 5 is arranged close to the housing air inlet 1031 to ensure that the controller 5 is well cooled. The housing 1 of this embodiment is an approximately closed shell with only two openings: the housing air inlet 1031 and the housing air outlet 1042. A casing air outlet 1042 is provided on a surface formed by a width W1 and a height H1 at the other end of the power station. The casing air outlet 1042 is formed on a casing air outlet cover 1041. The casing air outlet cover 1041 is connected to the rear panel 104. After cooling the power station, the heated air is discharged from the casing 1 through the casing air outlet 1042.

[0030] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the inverter 401 is accommodated in the inverter housing 402, and the inverter housing 402 is an approximately closed shell with only two openings: the inverter air inlet 403 and the inverter air outlet 404. The inverter housing 402 is made of metal aluminum or non-metal plastic and other materials, and the battery 6 and the inverter housing 402 are accommodated in the housing 1. The inverter housing 402 is an approximately rectangular parallelepiped shape with a length L, a width W and a height H, and the size relationship is: length L≥width W≥height H. An inverter air outlet 404 is provided on the surface formed by the width W and the height H at one end of the inverter cover 402. In order to obtain the best compactness and heat dissipation performance of the power station, the present invention arranges the length L of the inverter cover 402 longitudinally along the length L1 direction of the power station, that is, the length L direction of the inverter cover 402 is consistent with the length L1 direction of the power station. At the same time, the present invention arranges the inverter air outlet 404 on the side close to the casing air outlet 1042 to ensure the heat dissipation performance of the power station. An inverter air inlet 403 is provided on the surface formed by the width W and the height H at the other end of the inverter cover 402. In order to allow more cold air to enter the inverter cover 402, the present invention arranges the casing air inlet 1031 on one side of the inverter air inlet 403, that is: the inverter air inlet 403 is arranged on the side close to the casing air inlet 1031. As Figure 3 and Figure 4As shown, the height H of the inverter cover 402 of this embodiment is also consistent with the height H1 of the power station, and the width W of the inverter cover 402 is also consistent with the width W1 of the power station.

[0031] like Figure 4 , Figure 5 and Figure 6 As shown, considering the stability of the power station and the convenience of maintenance, the present invention arranges the battery 6 below the inverter cover 402. When the casing 1 is made of non-metallic materials such as plastic, the casing strength is poor. In order to increase the structural strength of the power station, a metal bracket 2 is arranged in the casing 1 of this embodiment, and the bracket 2 is mainly composed of an upper bracket 201, a lower bracket 202, connecting screws 203 and a liner 204. In this embodiment, the battery 6 is connected to the lower bracket 202, and is specifically arranged in a frame structure formed by the lower bracket 202. The inverter cover 402 is arranged between the upper bracket 201 and the lower bracket 202, and is connected to the top of the lower bracket 202. The upper bracket 201 and the lower bracket 202 are connected by connecting screws 203 and a liner 204.

[0032] like Figure 5 As shown, an inverter fan 405 is provided at the inverter air outlet 404 of this embodiment. The inverter fan 405 is driven by electricity, and the electricity comes from the battery 6. Under the drive of the inverter fan 405, the airflow enters the housing 1 from the housing air inlet 1031, first cools the controller 5, cools the battery 6 when flowing through it, and then enters the inverter cover 402 from the inverter air inlet 403 to cool the inverter 401. The flow direction of the cooling airflow in the inverter cover 402 is consistent with the length L direction of the inverter cover 402 and the length L1 direction of the housing 1, so that the inverter can obtain the best cooling effect. After cooling, the hot air is discharged from the inverter cover 402 from the inverter air outlet 404. Since the present invention sets the inverter air outlet 404 on the side close to the housing air outlet 1042, the hot air discharged from the inverter air outlet 404 can be easily discharged from the housing air outlet 1042 to the power station. In order to increase the exhaust speed of hot air, the present embodiment is provided with a fan 107 at the air outlet 1042 of the housing, and the fan 107 is driven by electricity, and the electricity comes from the battery 6, which helps to accelerate the exhaust of hot air from the housing 1. Of course, as needed, a fan driven by electricity can also be provided at the inverter air inlet 403 to accelerate the air flow into the inverter housing 402, further improving the cooling effect.

[0033] like Figure 5As shown, in order to prevent the hot air discharged from the inverter air outlet 404 from leaking into the inside of the housing 1, in this embodiment, an air outlet cover 108 is provided between the inverter air outlet 404 and the housing air outlet 1042, and a sealing ring 109 is provided on the side close to the housing air outlet 1042. The sealing ring 109 can be made of soft materials such as rubber to seal the hot air. The air outlet cover 108 is a ventilation duct, and its air inlet port is connected to the inverter air outlet 404, and the air outlet port is connected to the housing air outlet 1042 through the sealing ring 109.

[0034] like Figure 4 , Figure 6 and Figure 7 As shown, the battery 6 built into the power station has + / - pole terminals, and the battery 6 is placed in a frame structure formed by the lower bracket 202. A battery pressing plate 7 is provided on the outer side of the battery 6 close to the left casing 101. After removing the battery pressing plate 7, the battery 6 can be taken out of the frame structure of the lower bracket 202, and the battery 6 can be taken out of the casing 1 by opening the maintenance cover 1011, which is very convenient for maintenance.

[0035] like Figure 1 and Figure 8 As shown, in this example, a pull rod device 11 is also provided on the handle cover 105, and a roller device 10 is provided on the base 106. The power station can be conveniently moved by opening the pull rod and using the rollers, which greatly improves the portability of the energy storage power station.

[0036] In summary, the present invention sets the length direction of the inverter to be consistent with the length direction of the casing, and sets the inverter air outlet on the side close to the casing air outlet. Under the condition of ensuring the heat dissipation performance of the power station, the structural design of the power station is more compact and reasonable, which has obvious technical advantages.

[0037] Principle of the Invention

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, the inverter 401 of the present invention is accommodated in the inverter housing 402, and the inverter housing 402 is a rectangular parallelepiped structure with a length of L, a width of W, and a height of H. The inverter housing 402 is accommodated in the housing 1 of the energy storage power station, and the housing 1 is a rectangular parallelepiped structure with a length of L1, a width of W1, and a height of H1. In order to achieve the best structural compactness and heat dissipation performance, the length L of the inverter housing 402 is arranged along the length L1 direction of the housing in the present invention; Figure 5As shown, in order to improve the heat dissipation effect, the present invention arranges the inverter air inlet 403 on the side of the casing air inlet 1031, and arranges the inverter air outlet 404 on the side of the casing air outlet 1042, so that the hot air after cooling the inverter 401 can be more easily discharged to the outside of the casing 1, ensuring that the controller 5, the battery 6 and the inverter 401 can all be well cooled, thereby greatly improving the heat dissipation effect of the portable energy storage power station while ensuring the compactness of the structure.
