Description

Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to an outdoor energy storage power supply and energy storage device. Background Technology

[0002] Outdoor portable power banks are becoming increasingly popular and have a wide range of applications. They can provide temporary power for emergency situations and are very useful in scenarios such as outdoor camping, road trips, outdoor fishing, vehicle emergency use, medical equipment, and rescue and construction. They can power all kinds of electronic devices and tools.

[0003] Specifically, outdoor portable power banks are large-capacity, portable energy storage devices. Their structure typically consists of an outer protective casing housing an energy storage system. This system usually includes functional components such as battery cells, circuit boards, inverters, and a BMS (Battery Management System). The energy storage system stores electrical energy, converts current, and manages charging and discharging. It also has an input module for establishing a connection to charge the system; for example, an AC power outlet can be used to connect to AC power for charging.

[0004] Currently, most portable power banks on the market have similar input module designs. Specifically, manufacturers often use their own specific charging port designs. This means users need to use a charger or power adapter with a compatible charging port to charge the power bank, increasing its charging limitations and resulting in poor compatibility and flexibility, especially in situations where a compatible power adapter is unavailable and emergency charging is required. Examples include existing patents CN221614662U and CN111313498A. Utility Model Content

[0034] This disclosure provides an outdoor energy storage power supply, including a main housing, an end cap assembly, and an input assembly. The main housing has an energy storage cavity for fixing an energy storage system. The end cap assembly includes a front end cap and a rear end cap. The front end cap covers one end of the main housing, and the rear end cap covers the other end of the main housing. The input assembly includes a positive input terminal and a negative input terminal. The positive input terminal and the negative input terminal are respectively protruding from the end face of the rear end cap. One end of the positive input terminal and one end of the negative input terminal are electrically connected to the energy storage system, and the other ends of the positive input terminal and the negative input terminal are respectively used to connect to the mains power to charge the energy storage system.

[0035] Please see Figures 1 to 4 To better understand the outdoor energy storage power supply 10 of this application, the following further explanation is provided:

[0036] An outdoor energy storage power supply 10 according to one embodiment includes a main housing 100, an end cap assembly 200, and an input assembly 300. The main housing 100 has an energy storage cavity (not shown) for fixing and installing an energy storage system (not shown). The end cap assembly 200 includes a front cover 210 and a rear cover 220. The front cover 210 covers one end of the main housing 100, and the rear cover 220 is located at the other end of the main housing 100. The input assembly 300 includes a positive input terminal 310 and a negative input terminal 320. The positive input terminal 310 and the negative input terminal 320 are respectively protruding from the end face of the rear cover 220. One end of the positive input terminal 310 and one end of the negative input terminal 320 are respectively electrically connected to the energy storage system, and the other ends of the positive input terminal 310 and the negative input terminal 320 are respectively used to connect to the mains power to charge the energy storage system.

[0037] In this embodiment, by protruding the positive input terminal 310 and the negative input terminal 320 onto the end face of the rear cover 220, the user can charge the energy storage system either by using the plug terminals of a power adapter that is compatible with the positive input terminal 310 and the negative input terminal 320, or by using a power adapter without plug terminals for electrical connection. That is, the charging cable of the power adapter without plug terminals is directly connected to the other end of the positive input terminal 310 and the other end of the negative input terminal 320 for emergency charging, thereby improving the charging compatibility and flexibility of the outdoor energy storage power supply 10.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the positive input terminal 310 includes a positive support 3110 and a positive terminal 3120; the positive support 3110 covers a portion of the positive terminal 3120, the positive support 3110 protrudes from the end face of the rear cover 220, one end of the positive terminal 3120 is electrically connected to the energy storage system, and the other end of the positive terminal 3120 is connected to the mains power; the negative input terminal 320 includes a negative support 3210 and a negative terminal 3220; the negative support 3210 covers a portion of the negative terminal 3220, the negative support 3210 protrudes from the end face of the rear cover 220, one end of the negative terminal 3220 is electrically connected to the energy storage system, and the other end of the negative terminal 3220 is connected to the mains power.

[0039] It is understandable that by covering part of the positive terminal 3120 with the positive terminal support 3110, the stability of the electrical connection between one end of the positive terminal 3120 and the energy storage system is enhanced, and the structural wobbling of the positive terminal 3120 is prevented, thereby ensuring the stability of the connection between the other end of the positive terminal 3120 and the mains power. Similarly, by covering part of the negative terminal 3220 with the negative terminal support 3210, the stability of the electrical connection between one end of the negative terminal 3220 and the energy storage system is enhanced, and the structural wobbling of the negative terminal 3220 is prevented, thereby ensuring the stability of the connection between the other end of the negative terminal 3220 and the mains power.

[0040] like Figure 2 As shown, in one embodiment, both the outer peripheral walls of the positive terminal 3120 and the negative terminal 3220 are formed with external threads. Thus, when a user needs to charge the outdoor energy storage power supply 10 in an emergency, i.e., when there is no matching power adapter plug-in terminal nearby, the user can directly wrap and fix the power adapter's charging cable to the base of the positive terminal 3120 and the negative terminal 3220, and then use a washer nut to press and tighten the copper wire of the charging cable wrapped around the base of the positive terminal 3120 and the negative terminal 3220. Specifically, a washer nut is threaded onto the external threads of the positive terminal 3120 and the negative terminal 3220 respectively, thereby effectively ensuring the stability of the electrical connection during the charging process, and thus improving the charging compatibility and flexibility of the outdoor energy storage power supply 10. This ensures that the outdoor energy storage power supply 10 is not limited to the charging method of a specific or matching power adapter.

[0041] Furthermore, in other embodiments, the outdoor energy storage power supply 10 also includes an end cap, which is fitted onto the positive terminal 3120 or the negative terminal 3220, and serves as a dustproof and insulating protection. This significantly improves the safety performance of the outdoor energy storage power supply 10.

[0042] It should be noted that the washer nut is existing technology and will not be described in detail here.

[0043] like Figure 1 As shown, in one embodiment, the positive input terminal 310 and the negative input terminal 320 are arranged opposite to each other.

[0044] like Figures 2 to 4As shown, in one embodiment, the outdoor energy storage power supply 10 further includes a cooling fan 400, which is embedded in the rear end cover 220 and electrically connected to the energy storage system. In one embodiment, the front end cover 210 has multiple ventilation openings 2101, each of which is connected to the energy storage cavity. The cooling fan 400 forms a heat dissipation duct (not shown) with the energy storage cavity through the multiple ventilation openings 2101. The heat dissipation duct is used to guide the hot air generated after the cooling fan 400 cools the energy storage system.

[0045] It is understood that in this embodiment, the energy storage cavity of the outdoor energy storage power supply 10 is relatively compact. Therefore, by setting up the cooling fan 400 and the cooling air duct, the energy storage system can be maximized in the limited space of the energy storage cavity, thereby ensuring the normal charging and discharging and safe use performance of the outdoor energy storage power supply 10.

[0046] like Figure 4 As shown, in one embodiment, the front cover 210 is sequentially provided with a power switch button 2110, a display screen 2120, and a USB port 2102. In another embodiment, the front cover 210 is also provided with a socket 2130, which is used to connect an external plug and output current. This improves the practicality of the outdoor energy storage power supply 10 product, while also enhancing the user experience and ease of use.

[0047] like Figure 1 As shown, in one embodiment, the outdoor energy storage power supply 10 further includes a handle 500, which is located on the main housing 100 and fixedly connected to it. This facilitates the user's carrying or transportation of the outdoor energy storage power supply 10.

[0048] like Figure 3 As shown, in one embodiment, the main housing 100, the front cover 210, and the rear cover 220 are all integrally formed structures. This ensures the structural strength of the main housing 100, the front cover 210, and the rear cover 220, providing reliable protection for the energy storage system within the energy storage cavity.

[0049] This application also provides an energy storage device, including the outdoor energy storage power supply described in any of the above embodiments.

[0050] In this embodiment, by protruding the positive and negative input terminals onto the end face of the rear cover, users can charge the energy storage system either by using the plug terminals of a power adapter compatible with the positive and negative input terminals, or by using a power adapter without plug terminals for electrical connection. In other words, the charging cable of the power adapter without plug terminals is directly connected to the other end of the positive and negative input terminals for emergency charging, thereby improving the charging compatibility and flexibility of the energy storage device.

[0051] Compared with the prior art, the present invention has at least the following advantages:

[0052] By protruding the positive and negative input terminals onto the end face of the rear cover, users can charge the energy storage system either by using the plug terminals of a power adapter compatible with the positive and negative input terminals, or by using a power adapter without plug terminals for electrical connection. In other words, the charging cable of the power adapter without plug terminals can be directly connected to the other end of the positive and negative input terminals for emergency charging, thereby improving the charging compatibility and flexibility of the outdoor energy storage power supply.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
