Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a lithium battery for underwater working robots with water ingress detection function. Background Technology

[0002] Lithium batteries are batteries that contain lithium (including lithium metal, lithium alloy, lithium ion, and lithium polymer) in an electrochemical system. Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium ion batteries. Underwater robots need to use lithium batteries when working. However, existing lithium batteries are prone to damage and failure due to water ingress. In order to meet market needs, there is a need for a lithium battery for underwater robots with water ingress detection function.

[0003] Existing lithium batteries do not offer sufficient overall waterproofing, making them susceptible to water ingress and damage. Furthermore, they typically lack water ingress detection, preventing timely detection and automatic power cut-off, which can lead to hazards, increased maintenance costs, and downtime for underwater robots. In addition, existing lithium batteries are inconvenient to disassemble and reassemble, making it difficult for users to easily connect and disconnect the wires from the negative and positive terminals, thus hindering their operation. Utility Model Content

[0004] The purpose of this invention is to provide a lithium battery for underwater working robots with water ingress detection function, in order to solve the problems mentioned in the background art that lithium batteries usually do not have water ingress detection function and are inconvenient to operate when disassembling and using.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery for an underwater working robot with water ingress detection function, comprising a lithium battery body, the lithium battery body being composed of an upper shell, a potting hole, a wiring board, a lower shell, a battery pack, a mounting base, a negative terminal connector, and a positive terminal connector. The battery pack is placed on the surface of the mounting base. A wiring board is mounted on the surface of the top of the upper shell. A negative terminal connector and a positive terminal connector are mounted on the surface of the wiring board. The bottom ends of the negative terminal connector and the positive terminal connector respectively penetrate the wiring board and extend into the interior of the upper shell. A wire is sleeved on the surface of the negative terminal connector and the positive terminal connector. Water ingress detection mechanisms are provided at the corners of the surface of the battery pack and the inner wall of the lower shell. Quick disassembly and assembly mechanisms are provided on the surfaces of the negative terminal connector, the positive terminal connector, and the wire.

[0006] Preferably, the inner wall of the upper housing and the surface of the lower housing are interlocked, a mounting base is installed inside the lower housing, the surfaces of the upper housing and the mounting base are interlocked, the bottom end of the battery pack extends into the interior of the mounting base, and each surface of the upper housing has a potting hole, which is connected to the interior of the upper housing.

[0007] Preferably, the water ingress detection mechanism consists of a water ingress detection pad, a waterproof circuit board, a positioning post, and a positioning groove. The surface of the battery pack and the inner wall of the lower housing are both welded with water ingress detection pads, which are located at the corners of the inner wall of the lower housing and on the surface of the battery pack, respectively.

[0008] Preferably, a waterproof circuit board is welded to the surface of the water ingress detection pad, and positioning posts for positioning the waterproof circuit board are installed on the surface of the water ingress detection pad. Positioning grooves are opened on both sides of the waterproof circuit board, and the positioning grooves and the surfaces of the positioning posts are engaged with each other.

[0009] Preferably, the quick disassembly mechanism consists of a groove, a rubber sealing gasket, and a rubber clip. The inner wall of the wire is provided with a groove, and rubber clips are installed on the surfaces of both the negative terminal and the positive terminal. The rubber clips are made of rubber, and the rubber clips engage with the surfaces of the grooves.

[0010] Preferably, the surfaces of the negative terminal and the positive terminal are covered with rubber sealing gaskets for sealing the negative terminal and the wire body, as well as the positive terminal and the wire body, and the surface of the rubber sealing gasket is in contact with the inner wall of the wire body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the lithium battery for underwater working robots with water ingress detection function not only enables the lithium battery to detect water ingress in a timely manner and automatically cut off the power supply to prevent danger and reduce the maintenance cost of lithium batteries and the downtime of underwater working robots, but also makes it convenient for users to quickly disassemble and assemble the wires on the surface of the negative terminal and the positive terminal, making the lithium battery more convenient to operate during use. 1. By incorporating a water ingress detection mechanism, users can place the waterproof circuit board on the inner wall of the lower housing and the surface of the water ingress detection pads on the battery pack. The positioning pins and grooves work together to accurately and quickly position the waterproof circuit board during welding. When water enters the lithium battery through the gap between the upper and lower housings, water droplets adhere to the waterproof circuit board on the water ingress detection pads. This causes a short circuit between the two misaligned gold-plated pads on the detection pads. The short circuit then sends information to the feedback circuit, triggering a fuse on the waterproof circuit board. Once the fuse blows, the power supply to the lithium battery stops, improving its protection performance and enabling water ingress detection. This allows the system to detect water ingress promptly and automatically cut off the power, preventing accidents and reducing maintenance costs and downtime for underwater robots. 2. Equipped with a quick-release mechanism, the user pulls the cable, causing the rubber clips on the negative and positive terminals to move away from the grooves. At this point, the rubber sealing gasket moves away from the inner wall of the cable, allowing the cable to be quickly removed from the negative and positive terminals. When inserting the cable, the grooves and rubber sealing gaskets further enhance stability during insertion. The rubber sealing gaskets also ensure waterproofing between the negative and positive terminals and the cable, achieving quick disassembly of the lithium battery. This makes it convenient for users to quickly assemble and disassemble the cable on the negative and positive terminals, making the lithium battery easier to operate. Attached Figure Description

[0015] The present invention provides a lithium battery for an underwater working robot with water ingress detection function, the structure of which is as follows: Figures 1 to 4 As shown, the lithium battery body 1 comprises an upper housing 11, an encapsulation hole 101, a terminal block 102, a lower housing 103, a battery pack 104, a mounting base 105, a negative terminal port 106, and a positive terminal port 107. The inner wall of the upper housing 11 and the surface of the lower housing 103 are interlocked. The mounting base 105 is installed inside the lower housing 103. The surfaces of the upper housing 11 and the mounting base 105 are interlocked. The battery pack 104 is placed on the surface of the mounting base 105, and the bottom end of the battery pack 104 extends to the mounting base 104. Inside the 05, the surface of the upper housing 11 is provided with a potting hole 101, which is connected to the interior of the upper housing 11. A terminal block 102 is installed on the surface of the top position of the upper housing 11. A negative terminal 106 and a positive terminal 107 are installed on the surface of the terminal block 102. The bottom ends of the negative terminal 106 and the positive terminal 107 pass through the terminal block 102 and extend into the interior of the upper housing 11. A wire 108 is sleeved on the surface of the negative terminal 106 and the positive terminal 107.

[0016] Furthermore, such as Figure 3 and Figure 6 As shown, a water ingress detection mechanism 2 is provided at the corner of the surface of the battery pack 104 and the inner wall of the lower housing 103. The water ingress detection mechanism 2 consists of a water ingress detection pad 21, a waterproof circuit board 22, a positioning post 23, and a positioning groove 24. The water ingress detection pad 21 is welded to both the surface of the battery pack 104 and the inner wall of the lower housing 103. The water ingress detection pad 21 is located at the corner of the inner wall of the lower housing 103 and the surface of the battery pack 104, respectively. The surface of the water ingress detection pad 21 is welded to the waterproof circuit board 22. The surface of the water ingress detection pad 21 is equipped with a positioning post 23 for positioning the waterproof circuit board 22. Positioning grooves 24 are opened on both sides of the surface of the waterproof circuit board 22. The positioning grooves 24 and the surfaces of the positioning posts 23 are engaged with each other.

[0017] In practice, the user places the waterproof circuit board 22 on the inner wall of the lower housing 103 and on the surface of the water ingress detection pad 21 on the surface of the battery pack 104. With the combined action of the positioning post 23 and the positioning groove 24, the welding position of the waterproof circuit board 22 can be positioned, making the welding of the waterproof circuit board 22 more accurate and faster during the welding process. When water enters the interior of the lithium battery body 1 through the gap between the upper housing 11 and the lower housing 103, water droplets will adhere to the waterproof circuit board 22 on the surface of the water ingress detection pad 21. According to the prior art, the two misaligned immersion gold pads on the water ingress detection pad 21 will short-circuit. After the short circuit, the water ingress detection pad 21 will push the information to the feedback circuit and trigger the fuse on the waterproof circuit board 22 to blow. After the fuse blows, the power supply inside the lithium battery body 1 will stop, improving the protection performance of the lithium battery body 1. When water enters the interior of the lithium battery body 1, it can provide secondary protection for the lithium battery body 1 to realize the function of lithium battery water ingress detection.

[0018] Furthermore, such as Figure 5 and Figure 7 As shown, the surfaces of the negative terminal 106, the positive terminal 107, and the cable 108 are provided with quick-release mechanisms 3. The quick-release mechanism 3 consists of a groove 31, a rubber sealing gasket 32, and a rubber clip 33. The inner wall of the cable 108 has a groove 31. The surfaces of the negative terminal 106 and the positive terminal 107 are both equipped with rubber clips 33. The rubber clips 33 are made of rubber and are engaged with the surfaces of the grooves 31. The surfaces of the negative terminal 106 and the positive terminal 107 are covered with rubber sealing gaskets 32 for sealing between the negative terminal 106 and the cable 108, as well as between the positive terminal 107 and the cable 108. The surface of the rubber sealing gasket 32 ​​is in contact with the inner wall of the cable 108.

[0019] During implementation, the user pulls the cable 108, causing the rubber clips 33 on the surfaces of the negative terminal 106 and the positive terminal 107 to move away from the surface of the groove 31. At this time, the rubber sealing gasket 32 ​​moves away from the inner wall of the cable 108, allowing the cable 108 to be quickly removed from the surfaces of the negative terminal 106 and the positive terminal 107. When the cable 108 is inserted, the groove 31 and the rubber sealing gasket 32 ​​further improve the stability during insertion. Under the action of the rubber sealing gasket 32, the waterproof effect between the negative terminal 106 and the cable 108, as well as between the positive terminal 107 and the cable 108, is guaranteed, thus realizing the function of quick disassembly of the lithium battery.

[0020] Working principle: When in use, first install the lithium battery body 1 at the designated position on the underwater working robot. After installing the battery pack 104 on the surface of the mounting base 105, install the upper shell 11 on the surface of the lower shell 103. Fill the interior of the lower shell 103 and the upper shell 11 with glue through the glue filling hole 101, so that the upper shell 11 and the lower shell 103 can be sealed and waterproofed, making it difficult for external water to enter the interior of the lithium battery.

[0021] During use, due to factors such as sinking depth, lifespan limitations, or other reasons, water vapor may seep into the lithium battery. Water can easily enter the battery body 1 through the gap between the upper housing 11 and the lower housing 103, damaging the battery pack 104 and mounting base 105, causing the underwater robot to malfunction. Before applying adhesive to the interior of the upper housing 11 and lower housing 103, the user places the waterproof circuit board 22 on the inner wall of the lower housing 103 and on the surface of the water ingress detection pad 21 on the surface of the battery pack 104. The positioning post 23 and positioning groove 24 work together to position the waterproof circuit board 22, making the soldering process more precise and faster. When water seeps through the gap between the upper housing 11 and the lower housing 103... After entering the interior of the lithium battery body 1, water droplets adhere to the waterproof circuit board 22 on the surface of the water ingress detection pad 21. According to existing technology, the two misaligned immersion gold pads on the water ingress detection pad 21 will short-circuit. After the short circuit, the water ingress detection pad 21 pushes the information to the feedback circuit, causing the fuse on the waterproof circuit board 22 to blow. After the fuse blows, the power supply inside the lithium battery body 1 stops, improving the protection performance of the lithium battery body 1. When water enters the interior of the lithium battery body 1, it can provide secondary protection for the lithium battery body 1, so as to realize the function of lithium battery water ingress detection. This allows the lithium battery to detect water ingress in time and automatically cut off the power supply during use, preventing danger and reducing the maintenance cost of the lithium battery and the downtime of the underwater robot.

[0022] Subsequently, the cable 108 is inserted into the surfaces of the negative terminal 106 and the positive terminal 107 to connect to the lithium battery body 1. If the lithium battery body 1 needs to be used externally, the cable 108 needs to be quickly detached from the surfaces of the negative terminal 106 and the positive terminal 107. The user pulls the cable 108 so that the rubber clips 33 on the surfaces of the negative terminal 106 and the positive terminal 107 move away from the surfaces of the grooves 31. At this time, the rubber sealing gasket 32 ​​moves away from the inner wall of the cable 108, and the cable 108 can be quickly detached from the surfaces of the negative terminal 106 and the positive terminal 107. When the surface of 7 is removed, the groove 31 and the rubber sealing gasket 32 ​​can further improve the stability during insertion when the wire 108 is inserted. Under the action of the rubber sealing gasket 32, the waterproof effect between the negative terminal 106 and the wire 108, as well as between the positive terminal 107 and the wire 108, can be guaranteed, so as to realize the function of quick disassembly of the lithium battery. This makes it convenient for users to quickly disassemble and assemble the wire 108 on the surface of the negative terminal 106 and the positive terminal 107 when using the lithium battery, making the lithium battery more convenient to operate and finally completing the use of the lithium battery.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
