The present application provides an energy storage power supply 100 comprising: battery assembly 20, upper cover 30, lower cover 40, housing 10, and panel 50. The battery assembly 20 of the energy storage power supply 100 is used for storing electric energy, the upper cover 30 is located above the battery assembly 20, and the lower cover 40 is located below the battery assembly 20. The upper end of casing 10 is connected with upper cover 30, and the lower extreme of casing 10 is connected with lower cover 40 to make casing 10 and upper cover 30 and lower cover 40 between form hollow cavity 11, battery pack 20 sets up in this cavity 11, avoids battery pack 20 and external object to bump, leads to battery pack 20 to be damaged. The wall surface of the casing 10 is provided with a mounting hole 13, the panel 50 is mounted at the mounting hole 13, and the panel 50 is clamped with the upper cover 40 and the lower cover 40.

Thus, the energy storage power supply 100 can be installed from the bottom up. For example, the battery module 20 may be first mounted on the lower cover 40, the panel 50 may be mounted on the mounting hole 13 of the housing 10, the housing 10 may be mounted on the lower cover 40, the lower end wall surface of the panel 50 may be engaged with the lower cover 40, and the upper cover 30 may be mounted on the housing 10, and the upper cover 30 may be engaged with the upper end wall surface of the panel 50. Thus, compared with the prior art, the present application does not need to use screws for connection during the connection process, and during the process of installing the upper cover 30 and the housing 10, the panel 50 is clamped with the upper cover 30 and the lower cover 40, so that the degree of freedom of the panel 50 in space is limited, and the clamping process occurs during the process of installing the upper cover 40 and the lower cover 40, so that compared with the prior art, the installation process is reduced, the production efficiency is improved, and the production cost is reduced.

Fig. 5 shows a schematic structural diagram of a panel 50 provided in an embodiment of the present application. To further improve the connection strength of the panel 50 and the housing 10, in some embodiments, as shown in fig. 5, the panel 50 includes: the boss 52 and the abutment surface 53; the protruding portion 52 is fitted with the circumferential wall surface of the mounting hole 13, the protruding portion 52 is in clearance fit with the mounting hole 13, and the protruding portion 52 extends outward of the cavity 11 along the axial direction of the mounting hole 13. The abutting surface 53 is located in the cavity 11 and abuts against the inner wall surface of the housing 10.

In this way, the protruding portion 52 is engaged with the circumferential wall surface of the mounting hole 13, and the engaging surface 53 is engaged with the inner wall surface of the housing 10, so that the engagement between the engaging surface 53 and the inner wall surface of the housing 10 and the engagement between the protruding portion 52 and the mounting hole 13 both have a certain limiting effect on the movement of the panel 50, that is, the engaging surface 53 can limit the movement of the panel 50 along the axial direction of the mounting hole 13 and to the outside of the cavity 11. The boss 52 may limit the panel 50 to two degrees of freedom in space other than axial movement along the mounting hole 13. Thereby further improving the coupling strength of the panel 50 and the case 10.

It will be appreciated that the projection 52 extends axially of the mounting hole 13 toward the outside of the cavity 11 and may extend flush with the outer wall surface of the housing 10 in which the mounting hole 13 is located, as shown in fig. 1. That is, in some embodiments, the boss 52 includes: a connection surface 521 and a panel surface 522. The connection surface 521 is attached to a circumferential wall surface in the mounting hole 13, that is, the connection surface 521 is located in the mounting hole 13. The panel surface 522 is located outside the cavity 11, and the panel surface 522 and an outer wall surface (for convenience, hereinafter referred to as a second wall surface 14) of the housing 10 where the mounting hole 13 is located are located on the same plane. The panel surface 522 is also the first wall surface 51 of the panel 50 described above.

Thus, the second wall surface 14 is flush with the panel surface 522, and the joint of the second wall surface 14 and the panel surface 522 does not form a protrusion or groove structure, so that the operation of a user is facilitated, and the structure is overall attractive and elegant, and the visual experience of the user is improved.

In other embodiments, the protrusion 52 extends out of the cavity 11 along the axial direction of the mounting hole 13, and the panel surface 522 is located in the mounting hole 13, i.e. the junction of the second wall surface 14 and the panel surface 522 forms a groove structure. Thus, when the energy storage power supply 100 encounters rainwater, since the connection interface 515 on the connection surface 521 is located in the groove structure, rainwater can be prevented from directly dropping to the connection interface 515, and the panel surface 522 of the structure has a certain waterproof function.

To improve the space utilization of the panel 50, in some embodiments, as shown in fig. 3, the mounting holes 13 are oriented axially perpendicular to the panel face 522. That is, the axial direction of the mounting hole 13 is perpendicular to the second wall surface 14. Thus, the shape of the mounting hole 13 is relatively regular, and for example, the mounting hole 13 has a cylindrical shape or a rectangular parallelepiped shape as shown in fig. 3. In this way, the protruding portion 52 of the panel 50 fitted into the mounting hole 13 may be provided in a cylindrical shape, a rectangular parallelepiped shape as shown in fig. 4, or the like. Since the plurality of connection interfaces 515 are distributed on the panel surface 522 at intervals, the regular mounting holes 13 can accommodate more connection structures, thereby improving the space utilization of the panel 50.

In this way, the panel 50 and the lower cover 40 are clamped through the clamping groove 41 and the extension plate 54, so that the installation is convenient for workers and the installation efficiency of the workers is improved.

Wherein, optionally, one extension plate 54 can be provided as shown in fig. 5, and one locking groove 41 can be provided on the lower cover 40 as shown in fig. 6.

The specific number of the extension plates 54 and the card slots 41 is not limited in the present application, and may be set according to circumstances.

In addition, it will be appreciated that the lower cover 40 is provided with a locking slot 41 for cooperating with the extension plate 54. Therefore, in order to increase the portability of the energy storage power supply 100 and ensure that the lower cover 40 can bear a certain weight, the lower cover 40 has a certain thickness, and therefore, in one possible implementation, a grid-shaped rib 421 is provided on a wall surface (i.e., the third wall surface 42 in fig. 6) of the lower cover 40 close to the panel 50. Thus, the lower cover 40 can bear a certain weight, the weight of the energy storage power supply 100 is reduced, and the portability of the energy storage power supply 100 is improved.

In other embodiments, the wall of the faceplate 50 adjacent to the lower cover 40 is provided with a slot 41, and a third wall of the lower cover 40 is provided with an extension plate 54, wherein the extension plate 54 extends into the slot 41 and cooperates with the slot 41 to clamp the faceplate 50 to the lower cover 40. Therefore, when the panel 50 is installed, only the slot 41 of the panel 50 needs to be aligned with the extension plate 54 of the lower cover 40, so that the extension plate 54 extends into the slot 41, thereby facilitating the installation of workers.
