[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, a high-voltage energy storage cell protection device comprises a protective shell 1, a mounting plate 2 is arranged on the front surface of the protective shell 1, a fixing convex plate 3 is symmetrically arranged on the side surface of one end of the protective shell 1, a handle 5 is symmetrically arranged at the surface edge of the mounting plate 2, a mounting hole 4 is symmetrically opened on the surface of the fixing convex plate 3, a functional component is arranged inside the protective shell 1, and the functional component comprises an inner frame 6 arranged inside the protective shell 1, heat dissipation fins 8 are fixed at equal distances on the outer surface of the inner frame 6, a heat dissipation mesh plate 7 is installed at equal distances inside the inner frame 6, and a limiting plate 9 is symmetrically and equidistantly arranged on the inner wall of the inner frame 6, the limiting plate 9 is inclined toward the end of the mounting plate 2, the surface length of the limiting plate 9 is equal to the inner wall depth of the inner frame 6, and an elastic sheet 10 is fixed at equal distances between the inner surface of the limiting plate 9 and the inner wall of the inner frame 6, so as to improve the heat dissipation effect when the energy storage cell is placed inside the protective shell 1, so that the heat generated by the energy storage cell can be dissipated in time, so as to extend the service life of the energy storage cell, and the practical effect is good.

[0022] like Figure 4 and Figure 5As shown, a limit assembly is provided at the top of one side of the protective shell 1, and the limit assembly includes a connecting card plate 11 symmetrically arranged at the top of one side of the protective shell 1, and a telescopic spring 12 is installed between the inner surface of one end of the connecting card plate 11 and the outer surface of the protective shell 1, and a connecting card groove 13 for the other end of the connecting card plate 11 to engage is symmetrically opened at the top of the inner surface of the mounting plate 2, and the longitudinal section of the connecting card plate 11 is an inverted "J" shape, and the width of the opening of the connecting card groove 13 is greater than the width of the other end surface of the connecting card plate 11. A limiting protrusion 14 is fixed on the inner surface of the other end of the card plate 11, and a limiting groove 15 is provided on the inner wall of one side of the connecting card slot 13. The limiting protrusion 14 is engaged with the limiting groove 15. The cross-section of the limiting protrusion 14 is an isosceles trapezoid. The surface of the limiting protrusion 14 fits tightly with the temporal surface of the limiting groove 15, which is convenient for achieving a limiting connection when installing the mounting plate 2 and the protective shell 1, so that the mounting plate 2 will not loosen or fall off during the process of installing the bolts, which is convenient for improving the installation efficiency of the workers and has good practicality.

[0023] The utility model provides a high-voltage energy storage battery protection device, and the specific working principle is as follows: when the high-voltage energy storage battery is placed inside the protective shell 1 in the early stage of the utility model, the high-voltage energy storage battery is first pushed to move to the inside of the protective shell 1. At this time, the energy storage battery will be engaged with the inside of the built-in frame 6 inside the protective shell 1. At the same time, the side of the energy storage battery will squeeze the surface of the limiting plate 9, so that the elastic sheet 10 between the limiting plate 9 and the inner wall of the built-in frame 6 generates a moving rebound force until the energy storage battery is completely engaged with the inside of the built-in frame 6. At this time, the rebound force generated by the elastic sheet 10 will act on the limiting plate 9, so that the two limiting plates 9 on the inner wall of the built-in frame 6 can achieve limited clamping of the energy storage battery, and then the above steps can be repeated to install other energy storage batteries. At the same time, the heat dissipation mesh plate 7 inside the built-in frame 6 can separate the energy storage batteries so that there can be gaps between the energy storage batteries. In the later use process, the energy storage batteries can achieve good heat dissipation effect through the heat dissipation fins 8 on the surface outside the built-in frame 6, which is convenient for extending the service life of the energy storage batteries, and the practical effect When the mounting plate 2 is installed and connected with the protective shell 1, the connecting clamps 11 on both sides of one end of the protective shell 1 are first pressed, so that one end of the connecting clamps 11 squeezes the telescopic spring 12 until the other end of the connecting clamps 11 moves to a suitable position, and then the mounting plate 2 is pushed toward the surface of the protective shell 1. At this time, the other end of the connecting clamps 11 will be engaged with the inside of the connecting clamp groove 13 on the top surface of the mounting plate 2 until the other end of the connecting clamps 11 is completely engaged with the inside of the connecting clamp groove 13. The pressure on one end of the connecting card plate 11 can be released. At this time, the rebound force generated by the telescopic spring 12 will act on the connecting card plate 11, so that the limiting protrusion 14 on the inner side of the other end of the connecting card plate 11 will be limited and engaged to the inside of the limiting groove 15 on the inner wall of one side of the connecting slot 13, so that the mounting plate 2 can be limitedly connected with the protective shell 1, and then the workers can fix the mounting plate 2 with bolts. During the installation process, the mounting plate 2 will not easily loosen and fall off, which is convenient for improving the installation efficiency of the workers and has good practicality.
