Description

Technical Field

[0001] This utility model relates to the technical field of electrode plates for metal-air batteries, specifically to a quick-plug structure for metal-air battery electrode plates. Background Technology

[0002] In the stacking and assembly process of metal-air batteries, the positioning and fixing of the electrode plates (including anode and cathode) are crucial for achieving structural stability, minimizing contact resistance, and ensuring reliable sealing of the battery stack. Currently, the industry commonly uses bolts or a series of fasteners to fix the electrode plates one by one in series.

[0003] However, the existing bolt-fastening installation method has obvious technical limitations. Since the assembly process relies on the sequential tightening and loosening of multiple bolts, the operation is cumbersome and time-consuming, resulting in low efficiency in the assembly and maintenance of battery stacks. At the same time, when the bolt connection is pre-tightened, uneven contact pressure is easily generated at the mating surface of the electrode plate and the seal, which can easily form local gaps, affect the reliability of the sealing effect, and disrupt the uniformity of current conduction. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug structure for metal-air battery electrode plates, including a sealing frame and a top plate; The inner bottom of the sealing frame is provided with a placement groove for placing the electrode plate. The sealing frame has symmetrically provided limiting grooves on its inner side. A clamping plate is embedded inside the limiting groove, and an extension fixing plate is provided above and extends from the clamping plate. The top plate has two symmetrical slots on both sides, and a groove is formed inside the top plate. A locking block is fixedly connected to the side of the extension fixing plate. The outside of the locking block is inserted into the inside of the slot, and can slide vertically along the slot to fasten the top plate and the clamping plate. A sealing gasket is embedded inside the groove.

[0006] Preferably, the upper end of the extension fixing plate extends vertically to the outside of the top plate.

[0007] Preferably, both the top cross-section of the limiting groove and the groove are constructed into an H-shaped structure.

[0008] Preferably, the upper surface of the sealing gasket is configured as a concave structure, and the groove edge of the concave structure abuts against the lower surfaces of the extension fixing plate and the top plate respectively, forming a closed sealing strip area.

[0009] Preferably, the side of the sealing gasket abuts against the inner wall of the card block.

[0010] Preferably, the clamping plate and the extension fixing plate are made of silicone rubber.

[0011] Compared with existing technologies, this utility model achieves rapid insertion and secure fastening of electrode plates through a sliding locking structure between the sealing frame and the top plate, in conjunction with an extension fixing plate, a locking block, and an H-shaped limiting groove. The overall structure eliminates the bolt-by-point tightening process, and the assembly process can be completed by vertical sliding, significantly shortening the assembly and disassembly cycle of the electrode stack. The concave structure of the sealing gasket and the side pressure of the locking block form a multi-faceted contact sealing interface, ensuring uniform contact pressure distribution. This fundamentally improves the local gap problem caused by uneven bolt preload in traditional structures. The elastic structure of the clamping plate and the extension fixing plate can automatically compensate for pressure difference during assembly, maintaining the integrity of the fit and conductivity balance between the electrode plates.

[0014] 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.

[0015] Please see Figure 1 An embodiment of this utility model provides a quick-plug structure for metal-air battery electrode plates, including a sealing frame 10 and a top plate 15. like Figure 2 and Figure 3As shown, the inner bottom of the sealing frame 10 is provided with a placement groove 11 for placing the electrode plate. The inner side of the sealing frame 10 is symmetrically provided with a limiting groove 12. A clamping plate 13 is embedded in the limiting groove 12. An extension fixing plate 14 is provided above the clamping plate 13 and extends therefrom. Two slots 17 are symmetrically provided on both sides of the top plate 15. A groove 16 is provided inside the top plate 15. A locking block 19 is fixedly connected to the side of the extension fixing plate 14. The outside of the locking block 19 is inserted into the inside of the slot 17 and can slide vertically along the slot 17 to fasten the top plate 15 and the clamping plate 13. A sealing gasket 18 is embedded inside the groove 16.

[0016] According to the above technical solution, by setting a placement groove 11 at the bottom of the sealing frame 10 to support the electrode plate body, the electrode plate has a fixed placement position during installation. The limiting grooves 12 on both sides of the frame and the clamping plates 13 embedded therein form a symmetrical lateral limiting structure. The extension fixing plate 14 extending from the clamping plate 13 extends vertically to the top plate 15 to constrain the top of the electrode plate. The slot 17 on the top plate 15 cooperates with the locking block 19 on the side of the extension fixing plate 14. The locking block 19 can slide up and down along the slot 17, so that the top plate 15 and the clamping plate 13 are engaged when pressed down. The sealing gasket 18 in the groove 16 is pressed to form a closed sealing area after the top plate 15 is engaged, thereby realizing the rapid locking and sealing of the electrode plate.

[0017] In one embodiment, the upper end of the extension fixing plate 14 extends vertically to the outside of the top plate 15.

[0018] According to the above technical solution, the operator can directly apply hand force or mechanical pushing force through the external extension section to drive the locking block 19 to slide along the locking groove 17, thereby realizing the locking or unlocking of the top plate 15, which facilitates assembly and disassembly operations. The entire assembly process can be completed without tools, avoiding the multi-point tightening process of traditional bolt installation.

[0019] In one embodiment, the top cross-section of the limiting groove 12 and the groove 16 are both constructed as H-shaped structures.

[0020] According to the above technical solution, the upper and lower flanges of the H-shaped groove correspond to the edges of the clamping plate 13 and the top plate 15, respectively. During the assembly process, this double flange structure can form limiting constraints in both the vertical and horizontal directions. When the top plate 15 is pressed down, the clamping plate 13 moves along the inner wall of the H-shaped groove in a restricted manner, ensuring accurate sliding path and avoiding skew, thereby maintaining the flatness of the electrode plate pressure surface. This structure achieves stable guidance through geometric fit, without the need for additional guide pillars or limiting pins.

[0021] In one embodiment, the upper surface of the sealing gasket 18 is configured as a concave structure, and the edge of the groove 16 of the concave structure abuts against the lower surfaces of the extension fixing plate 14 and the top plate 15, respectively, to form a closed sealing strip area.

[0022] According to the above technical solution, when the top plate 15 is pressed down, the middle part of the concave area deforms after being pressed, and the concave edge and the contact surfaces on both sides generate uniform contact pressure, thereby achieving uniform distribution of the sealing medium. It can automatically compensate for the compression difference between assemblies with different thicknesses or small tolerances, so that the entire sealing area maintains a constant contact state. Compared with flat gaskets, the concave structure can simultaneously achieve bidirectional sealing in both radial and axial directions, improving the stability of the sealing interface.

[0023] In one embodiment, the side of the sealing gasket 18 abuts against the inner sidewall of the locking block 19.

[0024] According to the above technical solution, when the locking block 19 slides in the locking groove 17, its inner sidewall exerts a squeezing force on the sealing gasket 18, so that the sealing gasket 18 can be initially positioned before vertical pressing, preventing the sealing gasket 18 from shifting or curling during assembly. At the same time, this lateral abutment action can generate additional lateral pressure after the top plate 15 is locked, so that the edge area of ​​the sealing gasket 18 fits more closely with the inner wall of the limiting groove 12. This lateral locking structure further improves the overall closure of the sealing area, ensuring that gas or liquid media will not leak along the sidewall.

[0025] In one embodiment, the clamping plate 13 and the extension fixing plate 14 are specifically made of silicone rubber.

[0026] According to the above technical solution, the silicone rubber material can provide stable support while maintaining flexibility, so that the extension fixing plate 14 can adapt to the deformation under pressure when the top plate 15 is fastened, and realize the adaptive fit between the electrode plate and the sealing gasket 18. In addition, the high temperature corrosion resistance of silicone rubber can ensure that the structure maintains structural integrity and electrical insulation performance for a long time under electrolytic environment or high temperature operating conditions.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
