Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

As shown in Figures 1 to 4, a battery grid proposed in one embodiment of the present application includes:

The frame 1 is a quadrilateral frame 1, and its end is connected with a pole 2, and the pole 2 is an existing structure;

The skeleton 3 is a lead-calcium alloy skeleton with excellent electrical conductivity. The thickness of the skeleton 3 is smaller than the thickness of the frame 1. There are multiple through holes 4 evenly distributed on it. The radial cross-section of the through holes 4 is hexagonal. The holes 4 are combined with each other and arranged in a honeycomb shape on the end surface of the skeleton 3, and the peripheral sides of the skeleton 3 are connected to the inner wall of the frame 1. The hexagon has the largest area and the smallest perimeter. With this design, the skeleton 3 is in a honeycomb shape, which can provide a contact area between the skeleton 3 and the lead paste, so as to improve the stability of the combination between the skeleton 3 and the lead paste, so that the lead paste does not easily fall off from it and affect the normal operation of the lead-acid battery. Moreover, such a design consumes less material and helps to reduce production costs;

The fixing mechanism is arranged in the through hole 4 and is used to fix the lead paste on the frame 3. The fixing mechanism is used to improve the connection stability between the lead paste and the frame 3. The solidified lead paste can be further fixed through the fixing mechanism. , so that it is firmly connected to the skeleton 3 and is not easy to detach;

By adopting the design of the skeleton 3 in this application, compared with the existing square mesh ribs, the contact area between the skeleton 3 and the lead paste is larger, thereby improving the stability of the combination between the skeleton 3 and the lead paste. The lead paste is not easy to fall off and affect the normal operation of the lead-acid battery. Subsequently, the design of the fixing mechanism is used to further fix the solidified lead paste so that it is firmly connected to the skeleton 3 and is not easy to detach.

As shown in Figure 1 , in some embodiments, the frame 1 and the frame 3 are constructed as one piece. On the one hand, such a design facilitates casting, and on the other hand, it can effectively increase the connection strength between the frame 1 and the frame 3 and improve its deformation resistance. .

As shown in Figure 1, in some embodiments, connecting bars 5 are evenly distributed on the opposite ends of the skeleton 3, and the plurality of connecting bars 5 are respectively connected to the connecting ends of the through holes 4 and the tops of the through holes 4. Here, The top of the through hole 4 refers to the opposite end of the hexagonal through hole 4, and one end of the connecting strip 5 is connected to the inner wall of the frame 1 close to the tab 2.
