Description

Technical Field

[0001] This utility model relates to the field of portable charger technology, and in particular to a portable charger. Background Technology

[0002] A multi-layer stacked battery is a battery system composed of multiple individual cells connected in series. It is commonly used in hydrogen power generation and energy storage applications. Each individual cell consists of a combination of bipolar plates and membrane electrode assemblies. Multiple individual cells are stacked together through electrical connections so that electrical energy can be transferred between battery cells. Multi-layer stacking can effectively increase the power output of the battery.

[0003] Batteries with multi-layer stacked structures require strict sealing to prevent hydrogen leakage. Insufficient alignment between the battery casing and the cover shell, as well as insecure installation, may result in incomplete mating of the sealing rings and gaps between the casing and the cover shell, leading to reduced battery performance and unstable power output. Chargers using multi-layer stacked battery structures as their core have high power, strong stability, and higher output. This paper proposes a portable charger based on a multi-layer stacked structure as its core. Utility Model Content

[0004] The purpose of this invention is to provide a portable charger to solve the problem mentioned in the background art that gaps may occur in the contact between the multi-layer stacked battery casing and the cover shell, which leads to reduced battery performance and unstable power output.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a first reinforcing plate, a reinforcing plate, a limiting hole, a second reinforcing plate, a limiting strip, and a limiting nut. The battery stack is composed of multiple bipolar plates and membrane electrode assemblies. The multi-layer stacked structure facilitates the transfer of electrical energy between battery cells and allows for adjustment of the battery's output power as needed. After one side of the cover shell is tightly fitted to one side of the outer shell, the two limiting strips are threadedly connected to the corresponding limiting holes. Subsequently, the two limiting nuts are threaded onto one end of the limiting strips to limit and fix the first and second reinforcing plates, further enhancing the robustness of the installation between the outer shell and the cover shell.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a portable charger:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a portable charger includes a housing 1 and a cover 2. The cover 2 is disposed on one side of the housing 1. The housing 1 has a multi-layer electrode stack inside, which includes multiple bipolar plates 4 and multiple membrane electrode assemblies 5. A first reinforcing plate 6 is disposed on the top of the housing 1. Two reinforcing plates 7 are disposed on one side of the first reinforcing plate 6. Side plates 9 are fixedly installed on both sides of the first reinforcing plate 6. A stabilizing plate 10 is fixedly installed on one side of each of the two side plates 9. A protruding plate 15 is fixedly installed on both sides of the cover 2. Two limiting strips 13 are threadedly connected to corresponding limiting holes 8. Then, two limiting nuts 14 are threadedly sleeved onto one end of the limiting strips 13, which limits and fixes the first reinforcing plate 6 and the second reinforcing plate 12, further enhancing the firmness of the installation of the housing 1 and the cover 2.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4 As shown, a second reinforcing plate 12 is fixedly installed on the top of the cover shell 2. Two limiting holes 8 are opened on the other side of the first reinforcing plate 6. Two limiting strips 13 are provided on one side of the second reinforcing plate 12. One end of the two limiting strips 13 is threadedly connected to the two limiting holes 8 respectively. When the cover shell 2 gradually approaches the outer shell 1, the two protruding plates 15 gradually approach the two stabilizing plates 10. Due to the magnetic connection between the second magnetic strip 16 and the first magnetic strip 11, the cover shell 2 can be quickly fixed in the designated position.

[0026] Working Principle: A multi-layer stacked hydrogen fuel cell is a battery system composed of multiple individual cells connected in series. It is commonly used in hydrogen power generation and energy storage applications. Using this as a charger structure is more portable and efficient. Each individual cell consists of a bipolar plate 4 and a membrane electrode assembly 5. Multiple individual cells are stacked together via electrical connections to facilitate energy transfer between the battery units. Multi-layer stacking effectively increases the battery's power output, adapting to applications with high power requirements. In automotive applications, hydrogen fuel cell stacking can achieve longer driving range and faster energy replenishment. Fuel cells require strict sealing to prevent hydrogen leakage. Insufficient alignment of the battery casing 1 and the cover shell 2, or insecure installation, may result in incomplete sealing ring contact and gaps between the casing 1 and the cover shell 2, leading to reduced battery performance and unstable power output. Therefore, a portable charger is designed for this purpose. The battery is composed of multiple bipolar plates 4 and membrane electrode assembly 5. The multi-layer stacked structure facilitates the transfer of electrical energy between battery cells and allows for adjustment of the battery output power as needed. After one side of the cover shell 2 is tightly attached to one side of the outer shell 1, two limiting strips 13 are threaded to the corresponding limiting holes 8. Then, two limiting nuts 14 are threaded onto one end of the limiting strips 13 to limit and fix the first reinforcing plate 6 and the second reinforcing plate 12, further enhancing the firmness of the installation of the outer shell 1 and the cover shell 2. As the cover shell 2 gradually approaches the outer shell 1, the two protruding plates 15 gradually approach the two stabilizing plates 10. Due to the magnetic connection between the second magnetic strip 16 and the first magnetic strip 11, the cover shell 2 can be quickly fixed in the designated position. The magnetic connection provides a stable fixing force. The sealing rings installed on the outer shell 1 and the cover shell 2 are completely aligned, making the outer shell 1 and the cover shell 2 fit more firmly.
