[0027] Example 1

[0028] like Figures 1 to 6As shown, the embodiment of the present invention provides a horizontal lead-acid battery, including a battery housing 1 for enclosing electrical components, the battery housing 1 including positive and negative poles for outputting current, and the battery housing 1 is also provided with a liquid filling port for adding electrolyte, a mounting frame is fixedly connected to the inside of the battery housing 1, the mounting frame is tightly attached to the inner wall of the battery housing 1 and is fixedly connected to the inner wall of the battery housing 1, a plurality of groups of horizontally stacked bipolar plates 2 are provided inside the mounting frame, the bipolar plates 2 are fixedly connected to the inside of the mounting frame by a connector 3, and the mounting frame includes two groups of vertically arranged mounting plates 4 A partition is horizontally provided between the two groups of mounting plates 4. The partition and the mounting plate 4 are arranged perpendicular to each other and fixedly connected thereto. Multiple groups of bipolar plates 2 are evenly distributed on both sides of the partition. The battery housing 1 includes horizontally distributed positive plates and negative plates. A sealing partition 5 is provided between the positive plates and the negative plates. The side walls of the sealing partition 5 are fixedly connected to the inner walls of the battery housing 1 and divide the interior of the battery housing 1 into several groups of accommodating cavities. The positive plates and the negative plates are respectively arranged in different accommodating cavities. The battery housing 1 also includes a connecting rod 16 that passes through the positive plate and the negative plate. The connecting rod 16 passes through the sealing partition 5 and is connected to the connector 3.

[0029] like Figure 2 and Figure 3 As shown, the inner wall of the mounting plate 4 is evenly provided with several groups of fixed slots 6, and the fixed slots 6 are fixedly connected with limited blocking pieces 7. The limited blocking pieces 7 are located at the top of the fixed slots 6. The cross-section of the limited blocking pieces 7 is a right-angled triangle structure, and the inclined surface faces outward, which is convenient for guiding the connector 3 to be embedded in the fixed slots 6. At the same time, it can resist the connector 3 embedded in the fixed slots 6 to prevent it from detaching from the fixed slots 6. The inner wall of the mounting plate 4 is fixedly connected with a limited resisting strip 8, and the limited resisting strip 8 is located at the bottom of the fixed slots 6. The bottom of the connector 3 at the bottom layer will contact the limited resisting strip 8. When the upper connector 3 is pressed and moved downward, the limited resisting strip 8 provides support for the connector 3 to prevent all the connectors 3 from escaping from the mounting plate 4. The plate 4 is detached, resulting in the bipolar plate 2 being not firmly fixed. The cross-section of the connector 3 is a U-shaped structure, and the two ends are closed structures. The bottom of the connector 3 is provided with an arched portion 9, which is used to position and limit the connecting rod 16. The bottom of the connector 3 is also provided with multiple groups of lightweight grooves 12, which are used to reduce the dead weight of the connector 3, save materials, help reduce production costs, and also improve the heat dissipation effect of the connector 3. A plurality of groups of reinforcing ribs 11 are arranged horizontally on the top of the connector 3, and the reinforcing ribs 11 are arc-shaped groove structures. By providing the reinforcing ribs 11, the structural strength of the connector 3 can be increased, and the risk of bending in the middle of the connector 3 can be reduced. At the same time, it is convenient for the connector 3 to undergo axial compression deformation, which is convenient for the installation of the bipolar plate 2.

[0030] like Figures 4 to 6As shown, the inner side wall of the arched portion 9 is fixedly connected with a positioning protrusion 13, and the positioning protrusion 13 is provided with multiple groups and corresponds to the position of the connecting rod 16 one by one. The positioning protrusion 13 is a hemispherical structure, and there are arched protrusions at both ends of the connecting rod 16, and its structure is adapted to the arched portion 9. The inner ring side wall of the arched protrusion of the connecting rod 16 is provided with a positioning groove 17, and the positioning groove 17 is adapted to the positioning protrusion 13, and the positioning groove 17 corresponds to the position of the positioning protrusion 13 one by one. The cross section of the connecting rod 16 is an arc structure. When the connecting rod 16 is connected to the connecting member 3, the operator pushes the connecting rod 16 so that its end enters the interior of the connecting member 3. During the entry process, the arched protrusion of the connecting rod 16 will be deformed, so that the connecting rod 16 can smoothly enter the interior of the connecting member 3 and begin to recover the deformation when crossing the arched portion 9. Finally, the arched protrusion of the connecting rod 16 is stuck on the arched portion 9 to prevent the connecting rod 16 from moving back and forth and detaching from the connecting member 3. At the same time, during the installation of the connecting rod 16, the connecting rod 1 The arc groove of 6 corresponds to the positioning strip 10 in the connecting piece 3, and the positioning strip 10 enters the arc groove and engages with the connecting rod 16, thereby preventing the connecting rod 16 from moving left and right and detaching from the connecting piece 3. Because the inner ring wall of the arched protrusion of the connecting rod 16 is in close contact with the arched wall of the arched part 9, and the connecting rod 16 is positioned by the positioning strip 10, so that the positioning groove 17 thereon cooperates and connects with the corresponding positioning protrusion 13, further increasing the fixing effect of the connecting rod 16. The outer wall of the connecting piece 3 is fixedly connected to the fixing clip 14, and the top of the fixing clip 14 is provided with a limited locking groove 15. When the connecting piece 3 is installed on the mounting plate 4, the fixing clip 14 can be embedded in the fixing slot 6. The connecting pieces 3 at both ends of the bipolar plate 2 are respectively embedded in the two groups of mounting plates 4 on the mounting frame to achieve the purpose of fixing the bipolar plate 2. At the same time, the limiting block 7 inside the fixing slot 6 is embedded in the limiting locking groove 15, further increasing the stability of the connecting piece 3 and improving the firmness of the bipolar plate 2.

[0031] The working principle provided by the present invention is that when installing the battery, first, the two sets of connectors 3 are symmetrically installed at the two ends of the bipolar plate 2. When the connector 3 and the bipolar plate 2 are installed, the operator pushes the connecting rod 16 so that its end enters the interior of the connector 3. During the entry process, the arched protrusion of the connecting rod 16 will be deformed, so that the connecting rod 16 can smoothly enter the interior of the connector 3 and begin to recover the deformation when passing over the arched portion 9. Finally, the arched protrusion of the connecting rod 16 is stuck on the arched portion 9 to prevent the connecting rod 16 from moving back and forth and detaching from the connector 3. At the same time, during the installation of the connecting rod 16, the arc of the connecting rod 16 The groove corresponds to the positioning strip 10 in the connector 3. The positioning strip 10 enters the arc groove and engages with the connecting rod 16, thereby preventing the connecting rod 16 from moving left and right and detaching from the connector 3. Since the inner ring wall of the arched protrusion of the connecting rod 16 is in close contact with the arched wall of the arched portion 9, and the connecting rod 16 is positioned by the positioning strip 10, the positioning groove 17 thereon is matched with the corresponding positioning protrusion 13 to further increase the fixing effect of the connecting rod 16. After the connector 3 is installed at both ends of several groups of bipolar plates 2, the bipolar plates 2 are placed horizontally inside the mounting frame, and the two ends of the connector 3 are engaged with the mounting plate 4.

[0032] Push the connector 3 so that the fixing strip 14 on it is installed in the corresponding fixing slot 6, and in the process of the fixing strip 14 entering the fixing slot 6, push the limit block 7 to cause a small deformation, and finally make the limit block 7 embedded in the limit lock groove 15, so as to realize the locking connection between the connector 3 and the mounting plate 4. During the initial installation, the upper and lower adjacent two groups of bipolar plates 2 can be installed in two non-adjacent groups of fixing slots 6, thereby increasing the distance between the two groups of bipolar plates 2, providing sufficient space for installation, and thus improving the installation efficiency. When all the bipolar plates 2 are installed, the top bipolar plate 2 can be mechanically pressed to press the bipolar plates 2 in the same column together, reducing the distance between the two adjacent groups of bipolar plates 2 The spacing between them is large, and if the spacing between two adjacent groups of bipolar plates 2 is too large, after being subjected to sufficient pressure, the bipolar plate 2 on the upper layer moves downward, and the fixing card strip 14 disengages from the then fixing card slot 6 and moves downward along the side wall of the mounting plate 4 until it enters the next group of fixing card slots 6. The bipolar plate 2 moves downward until it contacts the top of the bipolar plate 2 of the next layer, and the lower bipolar plate 2 generates a supporting force for the upper bipolar plate 2. The bipolar plates 2 are mechanically pressed to make them stacked tightly, making the structure more compact. Finally, the top cover of the battery housing 1 is covered on the top of the battery housing 1 and sealed, and then sufficient electrolyte is added to the inside of the battery housing 1 through the liquid filling port on the battery housing 1.

[0033] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
