Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology. Background Technology

[0002] In the production process of lead-acid batteries, the assembly of large-sized batteries typically involves using a U-shaped liner to enclose the electrode group before placing them into the battery cell. Existing U-shaped liners (such as the lead-acid battery liner disclosed in Chinese Patent CN222546414U) are generally formed by bending the liner body, which includes a left frame, a right frame, and a connecting strip for connecting the left and right frames. The left and right frames of the liner body are bent along the ends of the connecting strip to form a receiving groove (i.e., the U-shaped liner). In use, the U-shaped liner is used in the battery assembly workshop to enclose the electrode group and install it into the battery cell. However, due to the limited width of the receiving groove bottom, it is difficult to accommodate electrode groups of different thicknesses. During assembly, the electrode group needs to be precisely placed inside the liner and ensure a tight fit with the battery cell, making the installation process complex. Furthermore, the U-shaped liner structure is relatively soft, resulting in significant variability during automated cell placement. It is prone to situations where the liner is not delivered properly, and it is also easy for the liner to fall off during the suction and movement process, affecting the efficiency and quality of automated production. Therefore, it is difficult to reliably apply it to automated assembly lines for large-sized lead-acid batteries. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and to provide a lead-acid battery electrode group liner.

[0004] The technical solution adopted by this utility model is: a lead-acid battery electrode group liner, the liner including a baffle and an electrode group guide plate connected to the upper edge of the baffle to facilitate the insertion of the electrode group into the battery slot.

[0005] The back of the baffle is provided with multiple vertical support plates; the multiple vertical support plates are two side support plates located at the left and right ends of the baffle and multiple intermediate support plates located between the two side support plates; at least two intermediate support plates are connected to an extension plate at the bottom to form a gap between the lower edge of the baffle and the bottom surface of the battery compartment to facilitate the flow of acid.

[0006] The outer side of the side support plate is provided with a limiting strip for cooperating with the limiting ribs in the battery slot to fix the liner plate in the battery slot.

[0007] Multiple parallel reinforcing ribs are connected between adjacent support plates on the back of the baffle.

[0008] The lower part of the limiting strip is provided with a guide strip to facilitate the insertion of the liner into the battery slot.

[0009] The connection between the pole group guide ramp and the upper edge of the baffle is rounded to facilitate the smooth entry of the pole group into the groove.

[0010] The upper part of the side support plate is provided with a beveled edge that is adapted to the pole group guide plate.

[0011] The side support plate and the upper edge of the pole group guide ramp are rounded, and the connection between the side support plate and the baffle and the pole group guide ramp is rounded to prevent the pole group from being bumped.

[0012] The extension plate is at least 10mm high.

[0013] In another aspect, this utility model provides a battery compartment, in which two lead-acid battery electrode group liners are assembled in each cell; and in each cell of the battery compartment, limiting ribs are provided for fixing the liners.

[0014] The inner wall of each battery compartment is provided with a small protrusion for supporting the side support plate and a large protrusion for supporting the middle support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the liner structure is reasonably and practically designed, and the baffle and support plate reliably fix the battery pack, preventing the battery pack from shifting under vibration and other working conditions, thus improving the stability of the battery pack; the whole piece is molded, which facilitates production and subsequent assembly, and can adapt to electrode groups of different thicknesses. It can be applied to the automated assembly production of large-scale lead-acid batteries. The liner provided by this utility model can be pre-stuck in the battery slot (completed in the plastic workshop).

Moreover, the liner structure is relatively hard, with small variables during automated slotting, and it is not easy for the liner to shift, thus improving the stability and quality of automated production.

[0024] Example 1: Liner

[0025] Figure 1 , Figure 2 As shown, the liner 1 includes a baffle 101 and a guide plate 102 connected to the upper edge of the baffle 101 to facilitate the placement of the electrode group into the battery slot. Multiple vertical support plates are provided on the back of the baffle 101. These multiple vertical support plates consist of two side support plates 103 located at the left and right ends of the baffle, and multiple intermediate support plates 104 located between the two side support plates 103. The baffle, combined with the support plates, provides support and fixation for the battery pack. Both the baffle and the support plates are made of high-strength plastic materials (such as polypropylene), possessing good rigidity and strength, effectively supporting and fixing the battery pack, and preventing displacement of the battery pack under vibration or other operating conditions.

[0026] At least two intermediate support plates 104 are connected at their lower parts to an extension plate 105 that creates a gap between the lower edge of the baffle 101 and the bottom surface of the battery compartment 2 to facilitate acid flow. The extension plate 105 has a height of 10±2mm.

[0027] The connection between the pole group guide ramp 102 and the upper edge of the baffle 101 is rounded with a chamfer 108 to facilitate the smooth entry of the pole group into the groove. The upper part of the side support plate 103 is provided with a bevel 1031 that is adapted to the pole group guide ramp 102. The upper edges of the side support plate 103 and the pole group guide ramp 102 are rounded, as are the connections between the side support plate 103 and the baffle 101 and the pole group guide ramp 102, to prevent the pole group from being bumped.

[0028] The outer side of the side support plate 103 is provided with a limiting strip 106 for cooperating with the limiting ribs inside the battery compartment 2 to fix the liner 1 inside the battery compartment 2. The lower part of the limiting strip 106 is provided with a liner guide 1061 to facilitate the insertion of the liner 1 into the battery compartment 2.

[0029] Multiple parallel reinforcing ribs 107 are connected between adjacent support plates on the back of the baffle 101 to enhance the rigidity and strength of the structure. The reinforcing ribs are made of high-strength plastic material and are integrally molded with the baffle and support plates, which improves the overall rigidity and strength of the structure and ensures the integrity of the structure under various working conditions.

[0030] The liner provided by this utility model can be pre-inserted into the battery slot (completed in the plastic workshop). When assembling the battery, the electrode group can be directly put into the slot without first wrapping the liner before putting it into the slot. It can be applied to the automated assembly production of large-scale lead-acid batteries.
