Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a local glue-filled waterproof battery and a glue-filling method thereof. Background Art

[0002] In the application of underwater or water equipment, such as water robots, surfboards, electric boats, underwater thrusters, etc., these devices usually rely on batteries to provide power. In order to ensure the reliability of batteries in humid or even submerged environments, the existing technology is to waterproof them through a full glue filling process. In this process, the entire battery pack, including battery cells, connectors and other electronic components, will be filled with sealant to form an overall waterproof barrier. Although the full glue filling process can protect each electronic component from interference, it also brings a series of problems: The full glue filling process will lead to a significant increase in battery weight. Due to the high density of the glue itself and the need to completely cover all parts of the battery, the full glue filling process will significantly increase the weight of the final battery. The increase in weight not only affects the portability and operational flexibility of the device, but also requires the device to consume more energy to overcome the resistance caused by its own weight, which directly affects the device's endurance.

[0003] The full glue pouring process also significantly increases the manufacturing cost. On the one hand, the material cost rises due to the increase in the amount of glue used; on the other hand, full glue pouring requires a more complicated process and takes longer to complete, which increases the production cost. The higher manufacturing cost will eventually be reflected in the selling price of the end product, affecting the economic efficiency and market competitiveness of the product.

[0004] With the development of market demand, users have put forward higher requirements for the protection level of equipment and also pay more attention to the lightweight of products. The traditional full-glue waterproof technology can no longer meet the needs of modern water or underwater equipment batteries, which has become a bottleneck restricting the development of such equipment.

DETAILED DESCRIPTION

[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods. Example

[0025] Please refer to Figure 1 and Figure 2 , an embodiment of the present invention provides a partially glue-filled waterproof battery, the partially glue-filled waterproof battery comprising: a battery module 1 and a glue-filled blister module 2, the glue-filled blister module 2 comprising a first blister unit 21 and a second blister unit 22 with built-in sealant; The first blister unit 21 and the second blister unit 22 are tray-shaped structures and are respectively sleeved on the electrical end 110 and the back end 111 of the battery module 1 .

[0026] Specifically, the existing battery glue filling is to fix the battery in a certain position, and then inject sealant into the surface of the battery from the outside, so that the sealant can completely cover the surface of the battery, and each part is completely sealed in the sealant, completely isolating the battery from the external environment.

[0027] The two ends of the battery module 1 are the electrical end 110 and the back end 111 of the battery module 1, respectively. The electrical end 110 and the back end 111 are the input end and the output end of the current in the battery module 1. The electrical end 110 and the back end 111 are generally connected in series and in parallel with the current conductor through welding. Therefore, the electrical end 110 and the back end 111 in the battery module 1 need to be sealed with sealant to prevent moisture from contacting the circuit and causing damage to the circuit components.

[0028] Preferably, the first blister unit 21 and the second blister unit 22 are tray-shaped structures with surrounding edges, and the first blister unit 21 and the second blister unit 22 are both provided with a blister groove, the blister groove of the first blister unit 21 is used for inserting the electrical end 110 of the battery module 1, and the blister groove of the second blister unit 22 is used for inserting the back end 111 of the battery module 1.

[0029] The first blister unit 21 is pre-filled with sealant, and then the electrical terminal 110 of the battery module 1 is inserted into the blister groove of the first blister unit 21, so that the sealant in the blister groove immerses the electrical terminal 110 of the battery module 1. When the sealant is cured, the electrical terminal 110 and the first blister unit 21 form a closed environment through the sealant, and the sealing of the electrical terminal 110 is completed. Similarly, after the sealing of the electrical terminal 110 is completed, the battery module 1 is turned over, so that the back end 111 is inserted downward into the blister groove of the second blister unit 22, so that the sealant in the blister groove immerses the back end 111 of the battery module 1. After the sealant is cured, the back end 111 forms a closed environment, and the sealing of the electrical terminal 110 is completed.

[0030] Preferably, in another embodiment, the electrical end 110 of the battery module 1 is first inserted vertically downward into the first blister unit 21, and then sealant is poured into the first blister unit 21 until the sealant in the first blister unit 21 immerses the electrical end 110 to a preset height. Similarly, after completing the sealing of the electrical end 110, the battery module 1 is turned over, the back end 111 is inserted into the second blister unit 22, and then sealant is poured into the second blister unit 22 until the sealant in the second blister unit 22 immerses the back end 111 to a preset height.

[0031] The partially glue-filled waterproof battery provided in this embodiment is configured such that the first and second blister units 21 and 22 with built-in sealants are sleeved at both ends of the battery module 1, so that the structure of the battery module 1 sleeved in the first and second blister units 21 and 22 can be sealed by the sealant, thereby preventing moisture in the external environment from contacting the structure, thereby achieving partial sealing of the battery module 1.

[0032] By partially sealing the two ends of the battery module 1, the amount of sealant used is reduced without reducing the waterproof function of the battery, thereby reducing the weight of the sealant in the battery, improving the portability of the battery and the flexibility of the device, and also reducing the energy consumed by the battery itself due to its weight, thereby improving the endurance of the device.

[0033] Reducing the amount of sealant used in the battery and reducing the cost of the sealant 524 itself also reduces the sealant filling time and the time waiting for the sealant to cure, thereby reducing the final manufacturing cost of the battery and improving the economy and market competitiveness of the battery itself.

[0034] At the same time, due to the reduction in the amount of battery sealant, the overall weight of the battery is reduced, realizing the lightweight design of the battery, which better meets the user's modern requirements underwater and on the water.

[0035] In one embodiment, if Figure 3 and Figure 4As shown, the battery module 1 includes: a plurality of battery cell units 12, a first battery cell bracket 13 and a second battery cell bracket 14, wherein the first battery cell bracket 13 and the second battery cell bracket 14 are respectively placed on the electrical end 110 and the back end 111; The plurality of battery cells 12 are arranged regularly, and the first battery cell holder 13 and the second battery cell holder 14 are respectively provided with plugging holes 15 corresponding to the plurality of battery cells 12 for inserting the battery cells 12, and baffles 16 are provided at the bottom of the plugging holes 15 for preventing the battery cells 12 from passing through the plugging holes 15; The first battery cell support 13 and the second battery cell support 14 are immersed in the sealant in the blister groove.

[0036] Specifically, the battery cell unit 12 is used to store and release electric energy.

The positive and negative electrodes of the battery cell unit 12 are respectively inserted into the plug-in hole 15 between the first battery cell bracket 13 and the second battery cell bracket 14. The baffle 16 blocks the battery cell unit 12 from passing through the bottom of the plug-in hole 15, so that several battery cell units 12 can be neatly and regularly arranged and fixed between the first battery cell bracket 13 and the second battery cell bracket 14.

[0037] The back end 111 is an end that only performs electrical connection between the battery cells 12 , and the electrical end 110 performs electrical connection between the battery cells 12 and also performs electrical connection between the battery cells 12 and the outside world.

[0038] In this embodiment, the fixing function of the first battery cell holder 13 and the second battery cell holder 14 ensures the stability of the battery cell unit 12 in the battery module 1, prevents the battery cell unit 12 from shifting or loosening during use, ensures the reliable connection of the battery cell unit 12 in the battery module 1, and improves the overall performance and service life of the battery module 1; the regularly arranged plug holes 15 allow the battery cell units 12 to be neatly arranged in a predetermined manner, improves the overall layout aesthetics and structural rationality of the battery module 1, and the baffle 16 at the bottom of the plug hole 15 can prevent the battery cell unit 12 from passing through the plug hole 15 during the insertion process, avoids the risk of excessive extension or displacement of the battery cell unit 12, and improves the safety of the battery module 1.

[0040] Specifically, the battery cell sampling unit 17 is used to collect information such as the voltage and temperature of the battery cell unit 12. The battery cell sampling unit 17 is arranged on one side of the battery cell unit 12 and is placed parallel to the length direction of the battery cell unit 12. The welding unit 18 is a welding nickel sheet with multiple regular openings. The welding unit 18 is placed at the electrical end 110 and the back end 111. The opening is used to pass through the baffle 16 arranged at the bottom of the plug-in hole 15 so that the welding unit 18 can contact the battery cell unit 12, so that it can be firmly welded and fixed to the battery cell unit 12 during later welding to ensure the transmission of electric energy.

[0041] Preferably, Figure 6 As shown, the battery module 1 includes a plurality of welding units 18, and the welding unit 18 includes a first welding portion 181 and a second welding portion 182 and a plurality of connecting portions 183 for connecting the first welding portion 181 and the second welding portion 182; the first welding portion 181 and the second welding portion 182 are arranged side by side and placed on the positive and negative electrodes of two adjacent rows of battery cell units 12 in the row direction, that is, the first welding portion 181 and the second welding portion 182 are placed between the baffles 16 set at the bottom of the plug-in hole 15, close to or in contact with the positive and negative electrodes of the battery cell units 12 in the plug-in hole 15, and the connecting portion 183 is placed between the baffles 16 set at the bottom of the plug-in hole 15 in the column direction, and the electric energy of two adjacent battery cell units 12 in the column direction is connected after welding. In this embodiment, the plurality of welding units 18, the first welding portion 181 and the second welding portion 182 on each welding unit 18, and the connecting portion 183 connecting the first welding portion 181 and the second welding portion 182 are realized to realize the series connection and parallel connection of a plurality of battery cells 12 in the battery module 1. When the battery module 1 is welded, after the electrical end 110 and the back end 111 are respectively inserted into the first blister unit 21 and the second blister unit 22, the sealant in the first blister unit 21 and the second blister unit 22 can complete the welding of the positive electrode, the negative electrode and the welding unit 18 of the immersed battery cell unit 12, and realize the complete sealing of the circuit for power transmission in the battery module 1.

[0042] like Figure 7As shown, the first welding portion 181 extends in the row direction close to the battery cell sampling unit 17 and is connected to the welding plate 171 on the battery cell sampling unit 17. The welding plate 171 is arranged on both sides close to the electrical end 110 and the back end 111, so that it can contact with the extended part of the first welding portion 181 to complete the welding and fixed connection between the first welding portion 181 and the welding plate 171. When the battery module 1 is inserted into the glue-filling blister module 2, the welding plate 171 and the first welding portion 181 can be completely immersed in the sealant to isolate the external environment.

[0043] In this embodiment, the battery module 1 can monitor the status of the battery cell unit 12 in real time through the battery cell sampling unit 17, which helps to promptly discover and deal with possible problems of the battery cell unit 12, thereby improving the safety of the system.

[0045] Through the cooperation of the screw hole 191 and the first screw column 172, the system management unit 19 can be fixed on the side of the battery module 1, and its plane is parallel to the battery cell sampling unit 17, so that the volume of each component in the battery module 1 is compact, reducing the space occupied by the battery module 1.

[0046] The cell sampling unit 17 is provided with a signal output terminal, and the system management unit 19 is provided with a signal receiving terminal. The signal output terminal and the signal receiving terminal are connected via a sampling line 192 to realize output of the signal from the cell sampling unit 17 to the system management unit 19 .

Example

[0069] Based on the local glue-filled waterproof battery provided in the above embodiment, this embodiment provides a glue-filling method for a local glue-filled waterproof battery, the method comprising: S1: according to the battery sealing requirements, a predetermined amount of sealant is placed into the first blister unit 21, and then one end of the battery module 1 is vertically inserted downward into the first blister unit 21; S2: Put a predetermined amount of sealant into the second blister unit 22 according to the battery sealing requirement, and turn over the battery module 1 after the sealant in the first blister unit 21 is cured; S3: insert the other end of the battery module 1 vertically downward into the second blister unit 22, wait for the sealant in the second blister unit 22 to solidify, and complete the glue filling of the local glue filling waterproof battery.

[0070] The method for locally glue-filled waterproof batteries provided in this embodiment is as follows: the sealant is pre-filled inside the first blister unit 21, and then the electrical terminal 110 of the battery module 1 is inserted into the first blister unit 21, so that the sealant in the first blister unit 21 immerses the electrical terminal 110 of the battery module 1. When the sealant is cured, the electrical terminal 110 and the first blister unit 21 form a closed environment through the sealant. Similarly, after the sealing of the electrical terminal 110 is completed, the battery module 1 is turned over so that the back end 111 is downwardly inserted into the second blister unit 22, so that the sealant in the second blister unit 22 immerses the back end 111 of the battery module 1. After the sealant is cured, the back end 111 forms a closed environment, thereby realizing local sealing of the battery module 1.

[0071] In one embodiment, before S1, the step further includes: Install a plurality of battery cells 12 on the first battery cell support 13 and the second battery cell support 14, and place the welding unit 18 on the electrical end 110 and the back end 111 of the battery module 1 for welding to connect the battery cells in series and in parallel; The battery cell sampling unit 17 is partially sealed and installed on the side of the battery cell unit 12, and the welding unit 18 and the welding plate 171 on the battery cell sampling unit 17 are welded and fixed; After partially sealing the system management unit 19, it is fixedly connected to the battery cell sampling unit 17, and connected to the total negative nickel sheet 102 through a wire, and connected to the battery cell sampling unit 17 through a wire; Connect the connector 4 to the total positive nickel sheet 101 and the system management unit 19 respectively.

[0072] In one embodiment, after S3, the method further includes: Place the battery module 1 and the connector 4 in the main body 32, fix the bottom end 42 and the main body 32 with screws, and inject sealant into the connector 4 located in the inner channel 3231; After the LED module 5 is installed, sealant is poured between the lens 521 of the LED module 5 and the upper cover 31 to complete the local glue filling and waterproofing of the battery.

[0073] This embodiment partially seals the battery module, connector, and LED module to reduce the amount of sealant used without reducing the waterproof function of the battery, thereby reducing the weight of the sealant in the battery, improving the portability of the battery and the flexibility of the device, while also reducing the energy consumed by the battery itself due to its weight and improving the battery life of the device.

[0074] Reducing the amount of sealant used in the battery and the cost of the sealant itself not only reduces the sealant filling time and the time waiting for the sealant to cure, but also reduces the final manufacturing cost of the battery and improves the economy and market competitiveness of the battery itself.

[0075] At the same time, due to the reduction in the amount of battery sealant, the overall weight of the battery is reduced, realizing the lightweight design of the battery, which better meets the user's modern requirements underwater and on the water.
