Description

Technical Field

[0002] At present, the outdoor energy storage power supplies on the market have won the favor of many consumers for their small size and beauty, which makes it more difficult for outdoor power supply manufacturers to design product size.

[0003] Because the product's internal structure contains numerous electronic modules and has minimal internal space, these modules can easily interfere with each other, impacting product performance. The inverter module in an outdoor energy storage power supply converts current, generating electromagnetic interference. When the energy storage power supply is equipped with a wireless charging module, the inverter module can interfere with the wireless charging module during operation.

[0004] An existing outdoor energy storage power supply has ventilation slots on both sides of the main body, which communicate with both the first and second cavities. A heat sink with several heat dissipation holes is fixedly mounted on the ventilation slots. By separating the inverter module and battery in the first and second cavities, heat generated by the battery during operation is prevented from penetrating into the inverter module and damaging its components. Ventilation slots on both sides of the main body promptly dissipate heat generated by the battery and inverter module, improving the heat dissipation performance of the energy storage power supply. However, when this outdoor energy storage power supply is equipped with a wireless charging module, the inverter module may interfere with the wireless charging module during operation.

The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0032] like Figures 1 to 3 As shown, it is a wirelessly rechargeable outdoor energy storage power supply 10 according to an embodiment of the present disclosure, including a shell assembly 100, a bracket assembly 200, an inverter module 300, a wireless charging module 400 and a shielding cover assembly 500. The inverter module 300 is used to convert the input and output currents of the battery cells. Specifically, the inverter module 300 converts the current output by the battery cells from DC to AC. The shell assembly 100 is provided with a receiving groove 101, and the bracket assembly 200 is installed in the receiving groove 101. The bracket assembly 200 is used to install battery cells and other electronic modules.

[0033] Furthermore, the inverter module 300 is installed on the bracket assembly 200, and the shielding cover assembly 500 includes an outer insulating layer 510, a metal shielding heat dissipation layer 520 and an inner insulating layer 530. The metal shielding heat dissipation layer 520 shields the electromagnetic field through the conductivity of the metal material and the absorption of electromagnetic waves. The inner insulating layer 530 covers the inverter module 300, and the metal shielding heat dissipation layer 520 covers the outside of the inner insulating layer 530 and is connected to the bracket assembly 200. The metal shielding heat dissipation layer 520 corresponds to the air duct of the shell assembly 100. The outer insulating layer cover 510 is provided on the outside of the metal shielding heat dissipation layer 520. The wireless charging module 400 is provided on the side of the outer insulating layer 510 away from the metal shielding heat dissipation layer, and the wireless charging module 400 is electrically connected to the inverter module 300.

[0034] In this embodiment, when the inverter module 300 is electrically connected to the battery cell, it converts AC and DC currents during charging and discharging, thereby generating electromagnetic interference. The wireless charging module 400 is charged based on electromagnetic induction. The metal shielding heat dissipation layer 520 is arranged between the wireless charging module 400 and the inverter module 300, so that the metal shielding heat dissipation layer 520 shields the electromagnetic interference between the inverter module 300 and the wireless charging module 400. The outer insulating layer 510 and the inner insulating layer 530 are arranged on the upper and lower sides of the metal shielding heat dissipation layer 520 to prevent the metal shielding heat dissipation layer 520 from contacting the wireless charging module 400 and the inverter circuit, thereby providing insulation protection for the metal shielding heat dissipation layer 520. The metal shielding heat dissipation layer 520 has good thermal conductivity, thereby accelerating the heat dissipation effect of the inverter module 300 and other heat-generating components that generate heat.

[0035] The wirelessly rechargeable outdoor energy storage power supply 10 is configured such that the outer insulating layer 510, the metal shielding heat dissipation layer 520, and the inner insulating layer 530 are sequentially arranged to cover the inverter module 300. This allows the metal shielding heat dissipation layer 520 to shield the electromagnetic field between the inverter module 300 and the wireless charging module 400, thereby resolving the mutual interference problem between the inverter module 300 and the wireless charging module 400. The outer insulating layer 510 and the inner insulating layer 530 are respectively disposed on the surfaces of the metal shielding heat dissipation layer 520 on both sides, thereby insulating the metal shielding heat dissipation layer 520 from the inverter module 300 and the wireless charging module 400, thereby improving the safety performance of the wirelessly rechargeable outdoor energy storage power supply 10. The metal shielding heat dissipation layer 520 is connected to the bracket assembly 200 and corresponds to the air duct of the housing assembly 100. The metal shielding heat dissipation layer 520 and the inverter module 300 have good thermal conductivity, thereby improving the ventilation and heat dissipation effect of the wirelessly rechargeable outdoor energy storage power supply 10, thereby improving the safety performance of the wirelessly rechargeable outdoor energy storage power supply 10.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, the outer insulating layer 510, the metal shielding and heat dissipation layer 520, and the inner insulating layer 530 are sequentially bonded; the sides of each of the outer insulating layer 510, the metal shielding and heat dissipation layer 520, and the inner insulating layer 530 are bent downward; a heat dissipation groove 5301 is formed below the inner insulating layer 530, and the inverter module 300 is disposed within the heat dissipation groove 5301. In this embodiment, a good heat dissipation channel is formed within the heat dissipation groove 5301. After the outer insulating layer 510, the metal shielding and heat dissipation layer 520, and the inner insulating layer 530 are bent, they are more closely bonded to the inverter module 300 and other modules mounted on the bracket assembly 200, thereby making the structure of the wirelessly rechargeable outdoor energy storage power supply 10 more compact and smaller in size.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, a metal connecting piece 521 is provided at the connection between the metal shielding heat dissipation layer 520 and the bracket assembly 200. The metal connecting piece 521 is attached to the bracket assembly 200 and is respectively connected to the bracket assembly 200 and the metal shielding heat dissipation layer 520. In this embodiment, a threaded connection hole is further provided at the connection between the bracket assembly 200 and the metal shielding heat dissipation layer 520. The metal connecting piece 521 has a through hole, through which the metal connecting piece 521 can be fixed to the bracket assembly 200 by screws. The metal shielding heat dissipation layer 520 is connected to the bracket assembly 200 via the metal connecting piece 521. The bracket assembly 200 is made of a metal thermally conductive material. The metal shielding heat dissipation layer 520 can transfer heat to the bracket assembly 200 via the metal connecting piece 521, thereby accelerating the heat dissipation of the inverter module 300 within the heat dissipation slot 5301.

[0038] like Figure 4 and Figure 5 As shown, in one embodiment, there are multiple metal connecting pieces 521. Several of the metal connecting pieces 521 on one side of the bracket assembly 200 are bent and connected horizontally to the top of the bracket assembly 200, while several of the metal connecting pieces 521 on the other side of the bracket assembly 200 are connected vertically to the side of the bracket assembly 200. In this embodiment, the metal connecting pieces 521 on the top of the bracket assembly 200 secure the metal shielding and heat dissipation layer 520 vertically, while the metal connecting pieces 521 on the side of the bracket assembly 200 secure the metal shielding and heat dissipation layer 520 horizontally, thereby improving the connection strength between the metal shielding and heat dissipation layer 520 and the bracket assembly 200 and preventing the metal shielding and heat dissipation layer 520 from shaking.

[0039] like Figure 2 As shown, in one embodiment, the wirelessly rechargeable outdoor energy storage power supply 10 further includes a cooling fan 600, which is disposed at the inlet and outlet of the heat dissipation slot 5301. In this embodiment, the cooling fan 600 blows air into the heat dissipation slot 5301, thereby forming a good heat dissipation channel in the heat dissipation slot 5301, thereby improving the heat dissipation effect of the inverter module 300 and other modules in the heat dissipation slot 5301.

[0040] like Figure 2 As shown, in one embodiment, the number of the cooling fans 600 is multiple, and each two cooling fans 600 are respectively disposed at the inlet and outlet at both ends of the heat dissipation slot 5301. In this embodiment, each two cooling fans 600 are disposed correspondingly at the inlet and outlet at both ends of the heat dissipation slot 5301, and the air outlet directions of the two cooling fans 600 are consistent, thereby forming a good heat dissipation air duct, making the air circulation speed of the heat dissipation air duct faster and the heat dissipation effect in the heat dissipation slot 5301 better.

[0041] like Figure 2 As shown, in one embodiment, the inverter module 300 and the wireless charging module 400 are spaced apart in the vertical direction. In this embodiment, the inverter module 300 and the wireless charging module 400 are spaced apart, which increases the distance between the inverter module 300 and the wireless charging module 400 and reduces interference between the inverter module 300 and the wireless charging module 400.

[0042] like Figure 2 As shown, in one embodiment, the housing assembly 100 includes an outer shell 110 and a bottom shell 120. The outer shell 110 is formed with the receiving groove 101. The outer shell 110 is covered on the bottom shell 120, and the bracket assembly 200 is connected to the bottom shell 120. In this embodiment, the bracket assembly 200 is connected to the bottom shell 120, and the outer shell 110 is covered on the bottom shell 120. The outer shell 110 and the bottom shell 120 are easy to assemble and disassemble, so that the structure of the wirelessly rechargeable outdoor energy storage power supply 10 is simple to assemble and produce.

[0043] like Figure 2 As shown, in one embodiment, the bottom of the bracket assembly 200 is provided with a battery cell mounting groove 201 for mounting a battery cell. The inverter module 300 is mounted above the bracket assembly 200 and is electrically connected to the battery cell. In this embodiment, the bracket assembly 200 sequentially layers the wireless charging module 400, the inverter module 300, and the battery cell, making the structure of the wirelessly rechargeable outdoor energy storage power supply 10 more compact, thereby reducing the volume of the wirelessly rechargeable outdoor energy storage power supply 10.

[0044] like Figure 2 As shown, in one embodiment, a vent 1101 is provided on the upper portion of the housing 110, and the vent 1101 corresponds to the position of the inner insulating layer 530. In this embodiment, the vent 1101 corresponds to the inlet and outlet of the heat dissipation slot 5301, and the vent 1101 corresponds to the air duct formed by the metal shielding heat dissipation layer 520 and the housing 110, thereby accelerating the circulation of hot air flowing out of the heat dissipation fan 600 and the vent 1101, thereby accelerating the heat dissipation speed of the wirelessly rechargeable outdoor energy storage power supply 10.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] 1. The wirelessly rechargeable outdoor energy storage power supply 10 is covered on the inverter module 300 by sequentially providing an outer insulating layer 510, a metal shielding heat dissipation layer 520, and an inner insulating layer 530. The metal shielding heat dissipation layer 520 shields the electromagnetic field between the inverter module 300 and the wireless charging module 400, thereby solving the problem of mutual interference between the inverter module 300 and the wireless charging module 400.

[0047] 2. The outer insulating layer 510 and the inner insulating layer 530 are respectively provided on the surfaces of both sides of the metal shielding heat dissipation layer 520, so that the metal shielding heat dissipation layer 520 is insulated from the inverter module 300 and the wireless charging module 400, thereby improving the safety performance of the wirelessly rechargeable outdoor energy storage power supply 10;

[0048] 3. The metal shielding heat dissipation layer 520 is connected to the bracket assembly 200 and corresponds to the air duct of the shell assembly 100. The metal shielding heat dissipation layer 520 and the inverter module 300 have good thermal conductivity, which improves the ventilation and heat dissipation effect of the wirelessly rechargeable outdoor energy storage power supply 10, thereby improving the safety performance of the wirelessly rechargeable outdoor energy storage power supply 10.
