Description

[0002] Currently, batteries for heavy-duty trucks are mainly designed according to the requirements of GB / T 5008.1-2013. The vibration performance requirements of these batteries must meet the 5G 8h vibration standard for Class B batteries in GB / T 5008.1-2013. However, actual usage shows that the actual needs of existing batteries far exceed this standard, especially during long-distance transportation where poor road conditions generate significant vibrations, causing internal battery components to shake and even leading to battery failure. Therefore, improving the vibration resistance of batteries is crucial for extending their lifespan and also affects their cycle life and overall performance. To address these issues, the industry has been continuously seeking new technical solutions. For example, some improvements attempt to enhance battery performance through optimized plate design and improved electrolyte formulation. However, these methods often only alleviate the problems to a certain extent and cannot fundamentally solve the core issues of poor vibration resistance and easy shaking of electrode groups in lead-acid batteries.

The terminal group includes a group of terminals and a busbar. The terminal group is located near the inner wall of each cell in the battery case. Each cell in the battery case is provided with a clamping member 3 for pressing the busbar from above and the terminal group from the side. The battery case 1 has 6 cells, and the terminal group 2 is located near the inner wall of each cell. The clamping member 3 is placed next to the terminal group within each cell of the battery case.

[0035] The clamping part 3 is made of PP material and is an irregular wedge shape. One side of the wedge is in close contact with the electrode group, and the flat side is in close contact with the outer partition of the battery compartment. It fixes the electrode group and prevents the electrode group from shaking from side to side during battery use, which could cause the electrode group plate ears to break or the lead paste on the plate to fall off.

[0036] The clamping component 3 includes a base plate 301, two flat panels 302 arranged parallel to the base plate 301, and a segmented clamping panel located between the two flat panels 302. Each end of the base plate has a flat panel, and the segmented clamping panel is located in the middle of the base plate, protruding 12mm from the flat panels. The segmented clamping panel is connected between the two flat panels 302 via two side walls 310 perpendicular to the flat panels 302. The base plate is 150mm high * 140mm wide, the flat panels are 150mm high * 25mm wide, and the segmented clamping panel is 150mm high * 90mm wide.

[0037] The segmented clamping panel includes a wedge-shaped panel 303 at the top for clamping the electrode group from the side, and a transition panel 304 at the bottom for easy insertion into the gap between the electrode group and the inner wall of the battery compartment. The transition panel 304 will not damage the electrode group when inserted next to it during installation. The wedge-shaped panel 303 has an angle α of 88° with the horizontal plane; the transition panel 304 has an angle b of 64° with the horizontal plane.

[0038] Busbar clips 305 are connected to the two flat panels 302; the lower part of the busbar clips 305 is provided with two clip corners 3051 for locking the busbar; the distance between the two clip corners 3051 is adapted to the length of the busbar.

The bottom of the triangular support rib group 307 is flush with the lower edge of the wedge-shaped panel 303; the height H1 of the triangular support rib group 307 is 60% of the height H0 of the wedge-shaped panel 303. The upper edge of the vertical connecting rib 306 is flush with the upper end of the triangular support rib group 307, and the lower edge is flush with the lower edge of the transition panel 304.

[0040] The base plate is connected to the flat panel and the segmented pressing panel by vertical connecting ribs 306 and reinforced by diagonal triangular support ribs 307. The vertical and diagonal reinforcing ribs do not protrude from the flat panel and the segmented pressing panel in the thickness direction.

[0041] The clamping component 3 has a support leg 308 at its lower part, located at the lower end of the vertical connecting ribs 3061 on both sides. The support leg 308 has a downward inclined surface 3081, which facilitates the insertion of the clamping component 3 into the pole group during installation without damaging the pole group. The angle c between the downward inclined surface 3081 and the horizontal plane is 61°. A reinforcing rib 3082 is provided between the support leg and the base plate to enhance the structural strength of the support leg.

[0042] The clamping component 3 has a apex 309 on its upper part for engaging with the cover to fix the clamping component. The purpose of the apex design is that after the clamping component 3 is installed and heat-sealed by the cover, the apex will press against the cover, fixing the clamping component 3 within its single compartment and preventing it from moving up or down. A reinforcing rib 3091 is provided between the apex 309 and the base plate 301 to enhance the structural strength of the apex.

[0043] Each flat panel of the clamping component 3 is provided with a busbar buckle 305. The busbar buckle 305 has buckle corners at both ends. The distance between the two buckle corners is equal to the length of the busbar. The busbar is fixed by the busbar buckle 305 to strengthen the stability of the busbar.

[0044] The wedge-shaped structure of the segmented pressing panel fits snugly against the electrode group to achieve a stable fixation of the electrode group; the busbar is fixed by the busbar clip to enhance the stability of the busbar.
