Embodiment Construction
[0037] Such as Figure 1-2 As shown, a horizontal lead-acid battery includes a tank body 1, a middle cover 2 and a protective cover 3, and the three parts form a battery box with a rectangular parallelepiped structure. Such as Figure 5 As shown, there is a compartment inside the tank body 1, which divides its inner cavity into a plurality of cells 12, and there is a step 13 matched with the middle cover near the mouth of the tank body 1, so that the surface of the battery box after assembly is smooth. Due to the large depth of the tank body, the two sides of the tank body 1 along the width direction have an inclination of 0.3-0.5 degrees. In order to compensate for the inclination, the two sides have a plurality of oblique ribs 11 . Setting the oblique ribs 11 helps to improve the strength of the tank body. In addition, when the battery box is close to the plane, ventilation channels are formed between the oblique ribs, which is helpful for heat dissipation.

The invention discloses a lead-acid storage battery, which comprises a tank body and a middle cover, wherein six pole groups arranged in a line along the length direction are arranged in the tank body; two pole groups on the edge are provided with pole posts passing through the middle cover; two connection terminals are fixed on the middle cover; each connection terminal comprises a first connection part connected with the corresponding pole post and a second connection part for being connected with an external wire; the two connection terminals are arranged at one side of the middle cover along the width direction and the second connection parts are led out from the side surface of the middle cover; and one connection terminal is directly connected with one pole post and the other connection terminal is connected with the other pole post through a patch cord. According to the lead-acid storage battery, one connection terminal is transferred to the same side as the other connection terminal by the patch cord, and furthermore, the connection part, connected with the external wire, of each connection terminal is led out from the side surface and the connection terminal is located on the top surface of the storage battery for connection when the storage battery is lay down for use.
Description
technical field [0001] The invention relates to a lead-acid storage battery, in particular to a horizontal lead-acid storage battery and a battery pack which are convenient for wiring. Background technique [0002] Lead-acid batteries are currently the most important power source for electric bicycles. Compared with lithium-ion batteries, they have the advantages of low price and good safety. Since the voltage and capacity of a single battery cannot meet the requirements of electric bicycles, it is generally necessary to assemble multiple batteries in series to form a battery pack and place them together in the battery box. Under normal conditions, the battery is placed upright (the plate is vertical), but long-term use will cause the acid layer to stratify and cause the battery to fail. Some studies have shown that placing the battery horizontally (plate level) can effectively solve this problem and improve battery life. [0003] For example, CN102222803A discloses a 12V ...
