Description

Technical Field

[0001] This utility model relates to the field of battery safety technology, and in particular to a battery protection structure for an oxygen generator. Background Technology

[0002] An oxygen concentrator is a device that separates and purifies oxygen from the air to meet medical, healthcare, or industrial needs. It uses molecular sieve adsorption, membrane separation, or low-temperature distillation technology to separate nitrogen and oxygen from the air, outputting high-concentration oxygen. In the medical field, oxygen concentrators are used to assist in the treatment of respiratory and cardiovascular diseases. In daily health care, they can alleviate fatigue and dizziness caused by oxygen deficiency. In industrial production, oxygen concentrators provide high-purity oxygen for smelting and chemical processes, improving production efficiency. Their ease of operation and stable oxygen production have made them important equipment for safeguarding health and promoting industrial development.

[0003] Oxygen concentrator batteries are energy storage devices that provide power to oxygen concentrators, requiring a balance between safety and stable battery life. They use lithium or lead-acid batteries to meet different power supply needs in medical, home, or industrial settings. Existing oxygen concentrator batteries are protected by shells made of ABS engineering plastic or aluminum alloy. These shells can be filled with EVA foam or silicone cushioning layers to absorb vibrations during movement. However, the thick shells cause the screw holes to strip during disassembly due to increased thickness. Furthermore, the cushioning layer is bonded to the shell, requiring damage to the shell to remove the battery during maintenance. Current technology embeds copper or stainless steel pre-embedded parts in the screw holes of the aluminum alloy or ABS shells, fixing the battery through hot-melt or injection molding processes. The high strength of the metal pre-embedded parts helps prevent stripping. However, the high temperature required for hot-melt fixing of copper pre-embedded parts can cause localized overheating and carbonization of the plastic around the screw holes, creating stress concentration points that make the battery more prone to breakage at the carbonized areas during disassembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a battery protection structure for oxygen concentrators, aiming to improve the existing technology that uses copper or stainless steel embedded parts to fix the battery in the screw holes of aluminum alloy or ABS shells through hot melting or injection molding processes. The high strength of the metal embedded parts is used to avoid stripping. However, the copper embedded parts need to be heated to high temperatures when hot melting, which can cause local overheating and carbonization of the plastic around the screw holes, forming stress concentration points. During disassembly, the plastic is more likely to break at the carbonized points.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery protection structure for an oxygen concentrator, comprising a battery cell, a protection mechanism installed on the outside of the battery cell for protecting the battery cell, and a discharge mechanism installed on the outer wall of the battery cell for safe discharge; the protection mechanism comprises a sleeve installed on the outside of the battery cell, an arc plate fixedly connected to the top front end of the outer wall of the sleeve, multiple slots opened on the right side of the outer wall of the sleeve, a protruding plate fixedly connected to the bottom front end of the outer wall of the sleeve, and a limit hook fixedly connected to the right front end of the outer wall of the sleeve.

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a battery protection structure for an oxygen concentrator, including a battery cell 1. A protection mechanism 2 is installed on the outside of the battery cell 1 to protect it. A discharge mechanism 3 is installed on the outer wall of the battery cell 1 for safe discharge. The protection mechanism 2 includes a sleeve 201 installed on the outside of the battery cell 1. An arc plate 202 is fixedly connected to the top front end of the outer wall of the sleeve 201. Multiple slots 203 are provided on the right side of the outer wall of the sleeve 201. A protruding plate 204 is fixedly connected to the bottom front end of the outer wall. A limit hook 205 is fixedly connected to the right front end of the outer wall of the sleeve 201. A limit ring 206 is fixedly connected to the bottom of the outer wall of the sleeve 201. The limit ring 206 is installed on the outer rear end of the protruding plate 204. A fixing bracket 207 is fixedly connected to the bottom of the outer wall of the sleeve 201. The fixing bracket 207 is installed on the outer rear end of the limit ring 206. A bolt 208 is threadedly connected to the bottom end of the fixing bracket 207. A nut 209 is threadedly connected to the left side of the outer wall of the bolt 208.

[0032] Specifically, the sleeve 201 tightly wraps around the outside of the battery cell 1, forming a fully enclosed protective structure, providing reliable physical protection for the battery cell 1 to resist external impacts. The arc plate 202 is installed at the top front end of the outer wall of the sleeve 201. Its unique arc design provides a leverage point for the user when replacing the battery, making it easy to remove the battery cell 1. The slot 203 is opened on the right side of the outer wall of the sleeve 201, and the limiting ring 206 is fixed at the bottom of the outer wall of the sleeve 201. Through the precise cooperation of the internal space and the external structure, the two securely fix the sleeve 201 in the designated position of the device. The protruding plate 204 is located at the bottom front end of the outer wall of the sleeve 201, which can effectively prevent the sleeve 201 from being fixed in place. If the device gets stuck due to positional deviation during use, the fixing bracket 207 is fixed to the bottom of the outer wall of the sleeve 201 to ensure smooth removal. The bolt 208 and nut 209 inside the bottom of the bracket cooperate with each other and connect with the fixing plate in the device, thereby precisely limiting the position of the sleeve 201 and ensuring that the battery cell 1 remains stable during operation and use. This solves the problem that when copper or stainless steel embedded parts are embedded in the screw holes of aluminum alloy or ABS shells and the battery is fixed by hot melting or injection molding, the hot melting of the copper embedded parts requires high temperature heating, which will cause local overheating and carbonization of the plastic around the screw holes, forming stress concentration points, and making it easy to break at the carbonized point during disassembly.

[0033] Reference Figure 2 , Figure 3 and Figure 5 The discharge mechanism 3 includes a housing 301, which is installed on the outer wall of the battery cell 1. A conductive plate 302 is installed inside the housing 301. The outer wall of the conductive plate 302 is fixedly connected to the outer wall of the battery cell 1. A discharge block 305 is fixedly connected to the front left side of the outer wall of the conductive plate 302. A base plate 303 is installed on the right side of the outer side of the conductive plate 302. Multiple fixing buckles 304 are fixedly connected at equal intervals on the left side of the outer wall of the base plate 303. A discharge groove 307 is opened on the left side of the front end of the outer wall of the housing 301. The interior of the discharge groove 307 is slidably connected to the outer wall of the discharge block 305. Multiple limiting grooves 306 are opened at equal intervals on the right side of the housing 301. The interior of the limiting grooves 306 is slidably connected to the outer wall of the fixing buckles 304.

[0034] Specifically, in the operation of the discharge mechanism 3, the battery cell 1 is first fixedly connected to the conductive plate 302 to establish the basic structure for power conduction. Then, the entire assembly is installed inside the housing 301. The discharge block 305 at the front end of the conductive plate 302 forms a sliding fit with the discharge groove 307 on the left side of the front end of the housing 301. This design allows the power generated by the battery cell 1 to be conducted through the conductive plate 302 to the discharge block 305 and stably released through the discharge groove 307. While achieving stable power output, the housing 301 provides physical protection for the battery cell 1, effectively preventing damage during equipment operation. Damaged by impact, the final step in the installation process is to precisely insert the fixing buckle 304 on the outside of the base plate 303 into the limiting groove 306 on the right end of the outer shell 301. This method securely installs the conductive plate 302 and the battery cell 1, providing a reliable guarantee for the stability of the discharge process. This addresses the issue that when the battery discharges, the voltage gradually decreases as the power is consumed. The motor and control circuit components in the oxygen concentrator require a stable voltage to function properly. Voltage fluctuations can lead to unstable power output of the oxygen concentrator, resulting in insufficient oxygen production, frequent restarts or shutdowns, and other issues that seriously affect oxygen production efficiency and the reliability of equipment operation.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A heat dissipation groove 308 is provided at the top center of the outer casing 301, and the heat dissipation groove 308 is provided on the outer top of the battery cell 1.

[0036] Specifically, the heat dissipation groove 308 at the top center of the outer casing 301 is opened around the top of the battery cell 1, which can dissipate the heat generated during the discharge process of the battery cell 1 in a timely manner, and avoid the performance and safety of the battery cell 1 due to excessive temperature.

[0037] Working principle: The sleeve 201 tightly wraps around the outside of the battery cell 1, forming a protective structure that provides physical protection for the battery cell 1. The arc plate 202 is installed at the top front end of the outer wall of the sleeve 201. When replacing the battery, its unique arc design makes it easy for the user to remove the battery cell 1. The slot 203 is opened on the right side of the outer wall of the sleeve 201, and the limiting ring 206 is fixed at the bottom of the outer wall of the sleeve 201. The two use the internal space and the external structure to fix the sleeve 201 firmly in the required position. The protruding plate 204 is located at the bottom front end of the outer wall of the sleeve 201, which can effectively prevent the sleeve 201 from being stuck and unable to be removed during the use of the equipment. Fixing bracket 207 is fixed to the bottom of the outer wall of the sleeve 201. The bolt 208 and nut 209 inside the bottom end of the sleeve cooperate with the fixing plate in the equipment, thereby precisely limiting the position of the sleeve 201 and ensuring that the battery cell 1 is always in a stable and safe state during operation and use. This solves the problem of fixing the battery by embedding copper or stainless steel pre-embedded parts in the screw holes of aluminum alloy or ABS shells and fixing the battery by hot melting or injection molding. The high strength of the metal pre-embedded parts can be used to avoid stripping. However, the copper pre-embedded parts need to be heated at high temperature when hot melting, which will cause local overheating and carbonization of the plastic around the screw holes, forming stress concentration points. During disassembly, it is easy to break from the carbonized area.

[0038] When the discharge mechanism 3 is working, the battery cell 1 is first fixedly connected to the conductive plate 302, and then the whole assembly is installed inside the housing 301. The discharge block 305 at the front end of the conductive plate 302 slides and engages with the discharge groove 307 on the left side of the front end of the housing 301, so that the electrical energy generated by the battery cell 1 is conducted through the conductive plate 302 to the discharge block 305 and released through the discharge groove 307. While ensuring the stability of the power, it can also protect the battery cell 1 and prevent it from being damaged by external impacts during the operation of the equipment. Then, the fixing buckle 304 on the outside of the base plate 303 is embedded into the limiting groove 306 on the right end of the housing 301 to complete the stable installation of the conductive plate 302 and the battery cell 1, ensuring the stability of the discharge process. This solves the problem that the voltage of the battery gradually decreases as the power is consumed during discharge, while the motor and control circuit components in the oxygen concentrator need a stable voltage to work properly. Voltage fluctuations will cause unstable power output of the oxygen concentrator, resulting in insufficient oxygen production, frequent restarts or shutdowns of the equipment, and affecting oxygen production efficiency and reliability.
