Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery production technology, specifically relating to a bottom elevation frame for a lead-acid battery pack and a lead-acid battery pack. Background Technology

[0002] A lead-acid battery is a type of storage battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. During discharge, the lead dioxide at the positive electrode and the spongy lead at the negative electrode are converted into lead sulfate; during charging, the lead sulfate at the positive and negative electrodes are converted back into lead dioxide and spongy lead, respectively. A single lead-acid battery cell has a rated voltage of 2.0V. Two to six single lead-acid batteries are connected in series to form lead-acid batteries with rated voltages of 4.0V, 6.0V, 8.0V, 10.0V, and 12.0V. Multiple lead-acid batteries connected in series form a lead-acid battery bank.

[0003] Utility model CN207490049U discloses a bottom-mounted design to prevent electrode deformation in a pure lead battery. The battery includes an outer casing disposed on the outside of the bottom-mounted design to prevent electrode deformation and forming an internal accommodating space. The outer casing includes a lower end face, a side end face, and a upper end face; a pressure pad disposed on the upper surface of the lower end face of the outer casing; and a reaction element disposed within the accommodating space of the outer casing, placed on top of the pressure pad. This utility model addresses the problems of electrode bending deformation and short circuits by creating a bottom-mounted design, thereby increasing the battery height.

[0004] As the energy density of lead-acid batteries continues to increase, newer batteries, with the same rated capacity, are smaller and shorter, making them incompatible with the battery boxes of older electric bicycles. Current technology offers limited optimization for the battery's bottom design; therefore, research into adjusting the battery height for the same rated capacity remains valuable. Utility Model Content

[0005] To address the aforementioned technical problems in the existing technology, this utility model provides a bottom elevation bracket for a lead-acid battery pack and a lead-acid battery pack.

[0006] This utility model provides a bottom raising bracket for lead-acid battery packs, including a fixed frame. The fixed frame is divided into several raising units by a partition. Each raising unit is enclosed by the fixed frame and the partition to form a receiving cavity. Each receiving cavity is provided with a support frame. The top surface of the support frame is lower than the fixed frame and the partition. In use, each lead-acid battery is placed in a corresponding raising unit, and the bottom of the lead-acid battery is inserted into the receiving cavity and supported on the support frame.

[0007] Furthermore, the height of the compartment spacer is consistent with that of the fixing frame, so that the top of the compartment spacer is flush with the top of the frame, forming a unified supporting plane, which not only enhances the overall structural strength and avoids local compression deformation, but also facilitates the stable installation and placement of the battery pack, and prevents shaking or damage caused by uneven supporting surface.

[0008] Furthermore, the number of the height-increasing units is 2-6, which are configured according to batteries with different quantities and sizes.

[0009] Furthermore, the height-increasing units are arranged in one row or two rows.

[0010] Furthermore, each supporting frame comprises a plurality of supporting sheets, and the supporting sheets in each supporting frame are arranged in an X shape, a cross shape, a丰 shape, an irregular cross structure, a parallel structure or a non-parallel non-cross structure.

[0011] Furthermore, the thickness of the compartment spacer allows adjacent assembled lead-acid batteries to fit closely or have a gap therebetween.

[0012] Furthermore, heat dissipation holes are further provided on the compartment spacer and the fixing frame to facilitate heat dissipation of the batteries.

[0013] The present utility model further provides a lead-acid battery pack, comprising the above bottom height-increasing rack for a lead-acid battery pack, wherein one lead-acid battery is assembled in each height-increasing unit of the bottom height-increasing rack for the lead-acid battery pack, and the lead-acid battery and the accommodating cavity of the height-increasing unit are fixed through interference fit or snap-fit connection.

[0014] Furthermore, there is a gap between adjacent assembled lead-acid batteries, and a buffer pad is placed in the gap. The buffer pad can prevent the batteries from moving and rubbing against each other, and is used to protect the battery tanks of the batteries.

[0025] Example 1 As shown in Figure 1 and Figure 2 , this embodiment provides a height-increasing frame for the bottom of a lead-acid battery pack, which consists of a fixed frame 1, a support frame 2 and a frame partition 3.

[0026] The interior of the fixed frame 1 is divided into a plurality of height-increasing units by the frame partitions 3. The number of the height-increasing units is 2 to 6, which is configured according to batteries of different numbers and sizes. In this embodiment, the number of the height-increasing units is 4. Each height-increasing unit is arranged in one row or two rows, and in this embodiment, each height-increasing unit is arranged in one row.

[0027] The height of the frame partition 3 is consistent with the height of the fixed frame 1, so that the frame partition 3 is flush with the top of the frame to form a unified support plane, which not only enhances the overall structural strength and avoids local compression deformation, but also facilitates the stable installation and placement of the battery pack, and prevents shaking or damage caused by uneven support surfaces.

[0028] An accommodation cavity is enclosed by the fixed frame 1 and the frame partition 3 in each height-increasing unit, and the support frame 2 is arranged in each accommodation cavity. The top surface of the support frame 2 is lower than that of the fixed frame 1 and the frame partition 3. In use, each lead-acid battery is correspondingly placed into one height-increasing unit, the bottom of the lead-acid battery is clamped into the accommodation cavity, and the bottom surface of the lead-acid battery is supported on the support frame 2.

In this embodiment, each support sheet is arranged in an "X" shape.

[0030] The thickness of the frame separator 3 allows adjacent assembled lead-acid batteries to be either tightly fitted together or have gaps. In this embodiment, the thickness of the frame separator 3 allows adjacent assembled lead-acid batteries to be tightly fitted together, such as... Figure 2 As shown.

[0033] Example 2 like Figure 3 and Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the frame 3 is thicker, which creates a gap between adjacent assembled lead-acid batteries, which is beneficial for battery heat dissipation.

[0034] Example 3 like Figure 4 As shown, the difference between this embodiment and embodiment 2 is that the frame 3 is provided with heat dissipation holes 4, which is more conducive to battery heat dissipation.
