[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] The housing of this invention is used in electronic devices, for example... Figure 1 The portable energy storage power supply shown is illustrated. It is understood that the housing of this invention is not limited to this, and can be applied to other types of electronic devices according to actual needs. The following description uses the housing as an example. Figure 1 The illustration uses the bottom shell of the portable energy storage power supply as an example. It can be understood that the shell of this utility model is not limited to this and can be set in other positions according to actual needs.

[0025] refer to Figures 2 to 6 In one embodiment, the housing 120 includes an outer shell 10 and an inner shell 20 fixed to the outer shell 10. A first surface 11 of the outer shell 10 and a second surface 21 of the inner shell 20 are opposite to each other and largely overlap. One of the first surface 11 and the second surface 21 is provided with a recess 31, and the other of the first surface 11 and the second surface 21 is provided with a protrusion 32 extending into the recess 31.

[0026] In one embodiment, the outer shell 10 and the inner shell 20 can be connected together by integral molding (e.g., injection molding). Multiple protrusions 32 can be provided as needed, extending into multiple recesses 31 respectively. Through the above structure, the connection strength between the outer shell 10 and the inner shell 20 can be guaranteed, so that the shell 120 will not be easily torn, causing the outer shell 10 and the inner shell 20 to detach from each other.

[0027] In one embodiment, the hardness of the outer shell 10 is less than that of the inner shell 20. For example, the outer shell 10 is a flexible plastic, and the inner shell 20 is a hard plastic. For example, the outer shell 10 is flexible silicone, and the inner shell 20 is a hard plastic or plastic. Thus, because the outer shell 10 is a flexible plastic capable of elastic deformation, it provides shock absorption while also offering a good feel. In the shell 120 as... Figure 1When the bottom shell of the portable energy storage power supply is shown, the outer shell 10 can absorb some or all of the vibrations when the portable energy storage power supply is placed on or dropped onto the supporting surface (such as the ground or other hard surfaces) when it is in direct contact with the supporting surface.

[0028] In one embodiment, the outer shell 10 is completely attached to the inner shell 20, that is, the first surface 11 of the outer shell 10 is attached to the second surface 21 of the inner shell 20.

[0029] In one embodiment, both the outer shell 10 and the inner shell 20 include a base plate and sidewalls connected to both ends of the base plate. Thus, the shell 120 is generally rectangular with one open side, a configuration that allows the open end of the shell 10 to align with the side shell (side plate) 200 of the portable energy storage power supply. It is understood that the construction of the shell 120 is not limited to the foregoing description, and other structures may be employed as needed. For example, it may be optional to not use the shell 120 to support the side shell (side plate) 200; in this case, the shell 120 may be designed to be generally flat.

[0030] In one embodiment, the sidewalls of the outer shell 10 and the sidewalls of the inner shell 20 have increased thickness at their respective ends. (See reference...) Figure 4 and Figure 5 The sidewall of the outer shell 10 includes an arc-shaped transition portion 12 and a thickened portion 13. The two ends of the transition portion 12 are connected to the bottom plate 14 of the outer shell 10 and the thickened portion 13, respectively. Figure 4 and Figure 5 As can be clearly seen, the transition portion 12 has a generally uniform thickness, while the thickened portion 13 gradually thickens from the bottom end connected to the transition portion 12 towards the top end. Similarly, the sidewall of the inner shell 20 includes an arc-shaped transition portion 22 and a thickened portion 23, with the two ends of the transition portion 22 connected to the bottom plate 24 of the inner shell 20 and the thickened portion 23, respectively. Figure 4 and Figure 5 As can be clearly seen, the transition portion 22 has a generally uniform thickness, while the thickened portion 23 gradually thickens from the bottom end connected to the transition portion 22 to the top end. The top ends of the thickened portion 13 and the thickened portion 23 are basically flush, providing a plane with sufficient width for supporting the side shell (side plate) 200.

[0031] In one embodiment, a positioning portion is provided at the end of the outer shell 10 or the inner shell 20. For example... Figure 6As shown, a positioning block 25 protrudes from the top of the inner shell 20, which is used to position the side shell (side plate) 200. Specifically, the bottom end of the side shell (side plate) 200 includes a contact side surface 210, which contacts the side surface of the positioning block 25, thereby positioning the side shell (side plate) 200 relative to the housing 120. This facilitates the installation of the side shell (side plate) 200, improves the stability of the side shell (side plate) 200 after installation, and ensures that the outer surface of the side shell (side plate) 200 is flush or smoothly transitioned with the outer surface of the outer shell 10 at the joint.

[0032] Understandably, in other embodiments, the positioning portion may protrude from the top of the outer shell 10. Of course, the positioning portion may also have other structures, such as a groove provided at the end of the outer shell 10 or the inner shell 20.

[0033] In one embodiment, to ensure the rigidity of the entire shell, a reinforcing rib 27 is formed on the third surface 26 of the inner shell 20 opposite to the second surface 21. By providing the reinforcing rib, a better rigidity is achieved, and the smoothness of the injection-molded appearance is also ensured, reducing the likelihood of defects. In one embodiment, the reinforcing rib 27 is a honeycomb structure composed of multiple interconnected polygonal structures, such as a honeycomb structure composed of regular hexagonal structures. It is understood that the structure of the reinforcing rib 27 is not limited to this, and other suitable structures can be adopted as needed.

[0034] In one embodiment, the outer surface of the base plate 14 is integrally formed with a plurality of anti-slip portions 141, for example, each anti-slip portion 141 is a raised structure arranged at intervals.

[0035] Based on the above description, those skilled in the art will realize that by making the outer shell from a soft material and the inner shell from a hard material, and by forming the outer and inner shells as a single piece through injection molding, the energy storage power supply can have comprehensive shock protection, which can greatly improve the safety and service life of the energy storage power supply.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
