[0027] like Figure 1 As shown, the embodiment of the present application provides a horizontal storage battery with an integral baffle, including a housing 100 and a battery body 20;

[0028] The shell 10 is a cavity structure composed of a shell 11 and a cover 12. The battery body 20 is arranged inside the shell 11. The cover 12 is formed with a positive electrode column hole 12a, a negative electrode column hole 12b and an acid addition hole 12c. The positive electrode column hole 12a and the negative electrode column hole 12b are symmetrically arranged on the plate surface of the cover 12. The acid addition hole 12c is located in the middle of the cover. Preferably, the acid addition hole 12c is located between the positive electrode column hole 12a and the negative electrode column hole 12b. A baffle 13 is provided near the opening of the shell 11. The baffle 13 is a porous fiber cotton board and completely covers the opening of the shell 11. The baffle 13 is provided with an elongated acid liquid through hole 13c corresponding to the acid addition hole 12c. An extension tube 125 is formed on the side of the cover 12 away from the battery body 20, and a safety valve 30 is sealed inside the extension tube 125.

[0029] The horizontal storage battery provided in the present application has a baffle 13 of a glass fiber structure, which has a large number of gas channels inside, but the glue cannot enter, so that the storage battery can be placed horizontally. When placed horizontally, the solid matter in the glue is blocked by the glass fiber, and the solid matter will not flow out from the inside of the battery to block the safety valve. During the use of the battery, there will be no problem with the gas discharge function of the safety valve.

[0030] The battery body 20 includes a positive electrode plate 21, a negative electrode plate 22, a separator 23, a positive bus bar 24, a negative bus bar 25, a positive electrode column 26 and a negative electrode column 27;

[0031] The positive plates 21 and the negative plates 22 are arranged in a cycle in sequence, and a partition 23 is arranged between each positive plate 21 and the adjacent negative plate 22. The positive plate 21 is electrically connected to the positive bus 24, and the negative plate 22 is electrically connected to the negative bus 25. The baffle 13 is formed with a first through hole 13a corresponding to the positive electrode column 26, and the baffle 13 is formed with a second through hole 13b corresponding to the negative electrode column 27. The positive electrode column 26 passes through the first through hole 13a and is arranged in the positive electrode column hole 12a, and the negative electrode column 27 passes through the second through hole 13b and is arranged in the negative electrode column hole 12b. The positive bus 24 and the negative bus 25 are arranged on the side of the baffle 13 away from the cover body 12, the positive electrode column 26 is electrically connected to the positive bus 24, and the negative electrode column 27 is electrically connected to the negative bus 25.

[0032] When the acid material is added into the housing 10 , most of the areas of the positive electrode plate 21 , the negative electrode plate 22 , and the separator 23 away from the cover 12 are covered by the acid material, forming an internal circuit of the battery.

[0033] The battery body also includes a pole fixing ring 28 and a sealing ring 29. The positive pole hole 12a and the negative pole hole 12b both extend inwardly with a receiving groove 121. The bottom of the receiving groove 121 is formed with an annular limiting edge 122. The side wall of the receiving groove 121 is formed with an internal thread. The sealing ring 29 is sleeved on the outer side of the corresponding pole and arranged in the receiving groove 121. The pole fixing ring 28 is sleeved on the corresponding pole and is threadedly connected with the internal thread, so that the sealing ring 29 contacts the annular limiting edge 122, which ensures that the pole is installed stably and forms a seal on the outer part of the pole.

[0034] In this application, the sealing connection of the safety valve 30 is in the following form:

[0035] Circumferentially extending fixed ridges 1251 are formed on opposite sides of the extension tube 125. The safety valve 30 includes a valve body 31, an elastic ring 32 and a locking portion 33. The lower portion of the valve body 31 is a cylindrical component 311. The locking portion 33 includes two oppositely arranged L-shaped limit strips 331 formed on the outer side of the cylindrical component 311. The elastic ring 32 is mounted on the upper end of the cylindrical component 311 for elastic contact with the upper end surface of the extension tube 125.

[0036] Specifically, the end face of the transverse portion of the L-shaped limit strip 331 close to the elastic ring 32 is a slope, and the end of the slope close to the vertical portion of the L-shaped limit strip 331 is closer to the elastic ring 32. With the above structure, when the L-shaped limit strip 331 is connected to the fixed edge 1251, as the safety valve 30 rotates, the slope on the L-shaped limit strip 331 contacts and gradually tightens with the fixed edge 1251, and the elastic ring 32 is appropriately compressed to ensure the sealing of the safety valve 30.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
