Description

Technical Field

[0001] This utility model relates to the field of lead-carbon battery technology, and in particular to a lead-carbon battery that is easy to assemble. Background Technology

[0002] The positive electrode of a lead-carbon battery is lead dioxide, the negative electrode is a lead-carbon composite electrode, and the electrolyte is a sulfuric acid solution. It incorporates carbon materials with capacitive properties (such as graphite, carbon black, activated carbon, carbon nanotubes, and graphene) into the negative electrode of a lead-acid battery. This is achieved through internal paralleling or internal mixing with the lead-acid battery, forming a dual-function energy storage battery that possesses both capacitive and battery characteristics. This type of battery leverages the advantages of supercapacitors' instantaneous high-capacity charging while also utilizing the specific energy advantage of lead-acid batteries.

[0003] However, existing technologies have some problems: when assembling the electrode assembly of existing lead-carbon batteries, workers usually need to repeatedly stack the positive electrode plate, separator and negative electrode plate, which takes a lot of time. At the same time, when installing the battery cover, glue is directly applied for fixation, which requires careful calibration to ensure that the cover is not misaligned. Therefore, we propose a lead-carbon battery that is easy to assemble. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lead-carbon battery that is easy to assemble. By modularizing the lead-carbon battery and setting electrode components and locking components, the lead-carbon battery can be quickly assembled.

[0005] This utility model is implemented as follows: a lead-carbon battery that is easy to assemble includes a shell, an inner cavity, multiple sets of baffles fixedly connected to the inner wall of the cavity, an electrode assembly disposed between every two sets of baffles, a sliding groove on the shell, a top cover slidably connected in the sliding groove, a locking assembly on the shell for fixing the top cover, an injection hole on the top cover, a cap threaded into the injection hole of the top cover, a sealing ring disposed between the cap and the top cover, an electrode plate fixedly connected to the inner wall of the top cover, and a terminal post fixedly connected to the top cover, the terminal post penetrating the top cover and fixedly connected to the electrode plate.

[0006] Optionally, the electrode assembly includes three sets of connecting plates, on which multiple sets of positive electrode plates, negative electrode plates and separators are fixedly connected at equal intervals, and the positive electrode plates, separators and negative electrode plates are arranged alternately in sequence.

[0007] Optionally, a column head is fixedly connected to the upper end of the connecting plate between the positive electrode plate and the negative electrode plate, and a connecting component is provided on the column head. The connecting component is used to connect the column heads on both sides of the baffle.

[0008] Optionally, the connecting assembly includes a connecting piece with a hole, a column head disposed in the hole, and a nut threaded onto the column head for fixing the connecting piece.

[0009] Optionally, the locking assembly includes a locking cylinder, a groove is provided on the outer shell, the locking cylinder is rotatably connected in the groove, a locking block is fixedly connected to the locking cylinder, a hole is provided inside the locking cylinder, and a square rod is slidably connected to the inner wall of the hole.

[0010] Optionally, a fixing block is fixedly connected to one end of the square rod, a locking groove is formed on the inner wall of the outer shell groove, the fixing block is disposed in the locking groove, a rotating groove is formed on the inner wall of the locking groove, and a spring is fixedly connected to the inner wall of the locking cylinder hole, and the spring is fixedly connected to the fixing block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model modularizes the positive electrode plate, negative electrode plate, and separator. During assembly, the entire positive electrode plate, separator, and negative electrode plate can be directly combined in sequence to form an electrode assembly. There is no need for workers to stack individual plates one by one, which speeds up the assembly process and avoids the risk of short circuits caused by workers forgetting to place the separator between the positive and negative electrode plates. At the same time, the connection between the two electrode assemblies is completed by fitting the connecting piece onto the post on both sides of the baffle and then locking it with a nut. There is no need for welding operations to connect them, which further speeds up the assembly of lead-carbon batteries.

[0013] 2. This utility model has a sliding groove and a locking assembly on the outer shell. The top cover is installed along the sliding groove of the outer shell. Then, pressing the square rod causes the fixing block on the square rod to pull the spring and move, thereby causing the fixing block to disengage from the locking groove and move into the rotating groove, so that the fixing block and the square rod can rotate. At this time, rotating the locking block causes the locking block to move to the top cover. Then, releasing the square rod will cause the fixing block to move into the locking groove and lock due to the spring's rebound force, preventing the fixing block from rotating. This also prevents the locking block from rotating, thus quickly fixing the top cover and preventing misalignment of the top cover, making it easier to assemble the top cover.

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown in the figure, the present invention provides a lead-carbon battery that is easy to assemble, including a shell 1. The shell 1 is rectangular and made of corrosion-resistant material. Its main function is to hold the electrolyte and electrode assembly 3, and to provide structural support for the battery.

[0026] Furthermore, a cavity is provided inside the outer shell 1, and multiple sets of baffles 2 are fixedly connected to the inner wall of the cavity. An electrode assembly 3 is provided between every two sets of baffles 2. The electrode assembly 3 includes three sets of connecting plates 31. Multiple sets of positive electrode plates 32, negative electrode plates 33 and separators 34 are fixedly connected at equal intervals on the three sets of connecting plates 31. The positive electrode plates 32, separators 34 and negative electrode plates 33 are arranged alternately in sequence.

[0027] Furthermore, a column head 35 is fixedly connected to the upper end of the connecting plate 31 on the positive electrode plate 32 and the negative electrode plate 33. A connecting component 6 is provided on the column head 35, which is used to connect the column heads 35 on both sides of the baffle 2.

[0028] Specifically, this utility model modularizes the positive electrode plate 32, the negative electrode plate 33, and the separator 34. During assembly, the entire positive electrode plate 32, separator 34, and negative electrode plate 33 can be directly merged in sequence to form an electrode assembly. There is no need for workers to stack individual plates in sequence, which speeds up the assembly process and avoids the risk of short circuits caused by workers forgetting to place the separator 34 between the positive electrode plate 32 and the negative electrode plate 33.

[0029] Furthermore, the connecting component 6 includes a connecting piece 61, which has a hole, and a post 35 is disposed in the hole. A nut 62 is threaded onto the post 35, and the nut 62 is used to fix the connecting piece 61.

[0030] Specifically, the connection of the two electrode groups can be completed by fitting the connecting piece 61 onto the post head 35 on both sides of the baffle 2 and then locking it with the nut 62. No welding operation is required for the connection, which further speeds up the assembly of the lead-carbon battery.

[0031] Furthermore, a sliding groove is provided on the outer shell 1, and the upper cover 4 is slidably connected in the sliding groove. A locking component 5 is provided on the outer shell 1 to fix the upper cover 4.

[0032] Specifically, the locking assembly 5 includes a locking cylinder 51, a groove is provided on the outer shell 1, the locking cylinder 51 is rotatably connected in the groove, a locking block 52 is fixedly connected to the locking cylinder 51, a hole is provided inside the locking cylinder 51, and a square rod 53 is slidably connected to the inner wall of the hole.

[0033] Furthermore, a fixing block 54 is fixedly connected to one end of the square rod 53, a locking groove is formed on the inner wall of the groove of the outer shell 1, the fixing block 54 is set in the locking groove, a rotating groove is formed on the inner wall of the locking groove, and a spring 55 is fixedly connected to the inner wall of the hole of the locking cylinder 51. The spring 55 is fixedly connected to the fixing block 54.

[0034] Specifically, the top cover 4 is installed along the sliding groove of the outer shell 1. Then, the square rod 53 is pressed, causing the fixing block 54 on the square rod 53 to pull the spring 55 to move, thereby causing the fixing block 54 to disengage from the locking groove and move into the rotating groove, so that the fixing block 54 and the square rod 53 can rotate. At this time, the locking block 52 is rotated, causing the locking block 52 to move to the top cover 4. Then, the square rod 53 is released, and the fixing block 54 will move into the locking groove and lock due to the rebound force of the spring 55, preventing the fixing block 54 from rotating. This also prevents the locking block 52 from rotating, thereby quickly fixing the top cover 4 and preventing the top cover 4 from being misaligned during the application of adhesive for sealing, which would cause poor sealing performance.

[0035] Furthermore, an injection hole is provided on the upper cover 4, and a cap 9 is threadedly connected to the injection hole of the upper cover 4. A sealing ring 10 is provided between the cap 9 and the upper cover 4. The sealing ring 10 is used to improve the sealing performance. The cap 9 can be removed by rotating it, and then electrolyte can be injected into the outer shell 1 through the injection hole. After completion, the cap 9 can be rotated back into the injection hole.

[0036] Furthermore, an electrode plate 7 is fixedly connected to the inner wall of the upper cover 4, and an electrode post 8 is fixedly connected to the upper cover 4. The electrode post 8 passes through the upper cover 4 and is fixedly connected to the electrode plate 7. The electrode plate 7 and the electrode post 8 are made of lead or lead alloy. Their main function is to connect the positive and negative terminals of the battery so that the battery can be connected to an external circuit.

[0037] The working principle of this utility model is as follows:

[0038] This utility model modularizes the positive electrode plate 32, negative electrode plate 33, and separator 34. During assembly, the entire positive electrode plate 32, separator 34, and negative electrode plate 33 can be directly combined to form an electrode assembly. There is no need for workers to stack individual plates one by one, which speeds up the assembly process and avoids the risk of short circuits caused by workers forgetting to place the separator 34 between the positive electrode plate 32 and the negative electrode plate 33. At the same time, the connection of the electrode assemblies on both sides is completed by fitting the connecting piece 61 onto the post head 35 on both sides of the baffle 2 and then locking it with the nut 62. There is no need for welding operations to connect them, which further speeds up the assembly of lead-carbon batteries.

[0039] This utility model has a sliding groove and a locking component 5 on the outer shell 1. The upper cover 4 is installed along the sliding groove of the outer shell 1. Then, the square rod 53 is pressed, which causes the fixing block 54 on the square rod 53 to pull the spring 55 to move, thereby causing the fixing block 54 to disengage from the locking groove and move into the rotating groove, so that the fixing block 54 and the square rod 53 can rotate. At this time, the locking block 52 is rotated, which moves the locking block 52 to the upper cover 4. At this time, the square rod 53 is released, and the fixing block 54 will move into the locking groove and lock due to the rebound force of the spring 55, preventing the fixing block 54 from rotating. This also prevents the locking block 52 from rotating, thereby quickly fixing the upper cover 4 and facilitating the assembly of the upper cover 4.

[0040] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
