Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to a lead-acid battery tank with an increased bottom height. 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, and 2 to 6 cells are often connected in series to form lead-acid batteries with rated voltages of 4.0V, 6.0V, 8.0V, 10.0V, and 12.0V.

[0003] Currently, the energy density of lead-acid batteries is continuously improving. However, with the same rated capacity, the new batteries are smaller in size, making them incompatible with the battery boxes of older electric bicycles.

[0004] 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.

[0005] Current technologies offer limited optimization for battery bottom design, but research on adjusting battery height for the same rated capacity remains significant. Utility Model Content

[0006] To address the aforementioned technical problems in the existing technology, this utility model provides a lead-acid battery case with an increased bottom height.

[0007] This utility model provides a lead-acid battery tank with an increased bottom, including a tank body. The lead-acid battery tank also includes a frame disposed at the bottom of the tank body for increasing the height of the tank body. The frame includes an outer frame with the same side perimeter as the side perimeter of the tank body. The frame and the tank body are integrally formed, or the frame and the tank body are separately injection molded and then assembled into one body.

[0008] Furthermore, the frame and the trough are integrally formed. The frame includes an outer frame formed by the four side walls of the trough extending downwards. A reinforcing rib is provided between the inner side wall of the outer frame and the bottom surface of the trough. The reinforcing rib can prevent the frame from deforming during production and use.

[0009] Furthermore, the frame and the groove are injection molded separately and then assembled into one piece; the bottom outer periphery of the groove has a reduced-size shaft opening, and the frame has a ring of holes on the inner side of the upper opening of the outer frame that are inserted into the shaft opening, and the shaft opening and the hole are connected by an interference fit.

[0010] Furthermore, the frame has a reinforcing rib on the inner side of the outer frame, below the opening, and after assembly, the top surface of the reinforcing rib abuts against the bottom surface of the groove.

[0011] Furthermore, the frame and the groove are injection molded separately and then assembled into one piece; the bottom outer periphery of the groove has a reduced-size shaft opening, and the frame has a ring of holes on the inner side of the upper opening of the outer frame that are inserted into the shaft opening, and the shaft opening and the hole are connected by a snap-fit.

[0012] Furthermore, the outer wall of the shaft opening is provided with a number of buckles at intervals, and correspondingly, the inner wall of the hole is provided with buckle holes at intervals that correspond one-to-one with the buckles.

[0013] Furthermore, the frame has a reinforcing rib on the inner side of the outer frame, below the opening, and after assembly, the top surface of the reinforcing rib abuts against the bottom surface of the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a lead-acid battery compartment with an increased bottom height, which solves the problem of different battery heights under the same rated capacity. It is compatible with battery boxes of new and old electric bicycles that meet national standards and is easy to install. Attached Figure Description
