Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0037] The utility model proposes an energy storage device with an integrated handle design. The integrated handle uses an inlay as support and filling to form the integrated handle and at least part of a shell component of the energy storage device as one piece, and further enables the integrated handle to be integrally connected to at least part of the shell component. Compared with the design of a separate handle used in most energy storage devices on the market, the human-machine experience is better, the mechanical strength of the handle is stronger, and the simple appearance design makes the product more integrated.

[0038] like Figure 1 As shown, the preferred embodiment of the utility model discloses an energy storage device, including a housing assembly 10 and a handle assembly 20, Figure 4 and Figure 5 The handle assembly 20 includes an integrated handle 21 and an inlay 22. The inlay 22 is embedded in the integrated handle 21, and both ends of the integrated handle 21 are integrally connected to at least part of the shell assembly 10. The side wall of the integrated handle 21 is spaced apart from the outer wall of the shell assembly 10.

[0039] The housing assembly 10 includes a front plate 11, a lower cover 12 and an upper cover 13. The lower cover 12 and the upper cover 13 are detachably connected, and the front plate 11 is connected between the lower cover 12 and the upper cover 13. Figure 2 , both ends of the integrated handle 21 are integrally connected to the upper cover 13, and the side wall of the integrated handle 21 is spaced apart from the outer wall of the upper cover 13. Specifically, the integrated handle 21 is integrally connected to the rear side edge of the top surface of the upper cover 13. In this embodiment, the integrated handle 21 is located at the middle position of the rear side edge of the top surface of the upper cover 13, that is, the integrated handle 21 is located within the projection range of the housing assembly 10, and is not protruding, so that the overall appearance is more beautiful. In other embodiments, the integrated handle 21 can also be protrudingly connected to the rear side edge of the top surface of the upper cover 13.

[0040] Furthermore, combined with Figure 3 An arc-shaped groove 311 is provided on the peripheral wall of the first hole 31 formed by the integrated handle 21 and the top surface of the upper cover 13, and an arc-shaped groove 321 is provided on the peripheral wall of the second hole 32 formed by the integrated handle 21 and the rear wall of the upper cover 13, wherein the arc-shaped groove 311 and the arc-shaped groove 321 are respectively cylindrical grooves, and the hand can be inserted into the groove to hold the integrated handle 21, and the side wall of the integrated handle 21 is chamfered along the length direction to prevent burrs and sharp edges, and avoid the feeling of foreign matter or cutting the human hand when the human body grasps it. In some other embodiments, the first hole 31 and the second hole 32 can also be provided with a chamfered or chamfered structure respectively to replace the arc-shaped groove structure. By providing these chamfered, chamfered or groove structures, the user can have a better gripping feel when grasping the integrated handle, thereby improving the user experience.

[0041] like Figure 2 As shown, in this embodiment, an anti-slip portion 211 is provided on the outer side wall of the integrated handle 21 opposite to the upper cover 13. Specifically, the anti-slip portion 211 is a plurality of parallel grooves provided on the outer side wall of the integrated handle 21 opposite to the upper cover 13. These grooves can be provided in parallel along a direction perpendicular to the length of the integrated handle 21, for example. By providing a groove texture structure as the anti-slip portion 211 of the integrated handle 21, the gripping feeling of the human body is increased and an anti-slip effect is provided when grasping. The sharp edges on the groove texture can also be rounded. In other embodiments, the anti-slip portion 211 can be provided on the entire outer side wall of the integrated handle 21.

[0042] In the energy storage device of this embodiment, the integrated handle 21 is integrally injection molded with the upper cover 13, that is, the integrated handle 21 and the upper cover 13 are made of the same material. The design method of filling the integrated handle 21 with an inlay 22 is adopted. The inlay 22 is added to the mold of the upper cover 13 as a support and filling structure during the injection molding of the plastic part. The inlay 22 is a separate part. In a specific embodiment, the inlay 22 is also separately injection molded using plastic material in advance. Before the injection molding of the upper cover 13, it is placed in the plastic upper cover mold as a filling part. After the injection molding of the upper cover 13, the inlay 22 and the upper cover 13 are combined into a whole and ejected from the mold together. Among them, the inlay 22 is not a real grip and does not come into direct contact with the user. It only plays a supporting and filling role during the injection molding of the structure of the integrated handle 21 integrally molded with the upper cover 13. Therefore, the inlay 22 is only a separate part embedded in the integrated handle 21 after the upper cover 13 and the integrated handle 21 are molded.

[0043] According to the characteristics of plastic part molding, the wall thickness of the plastic part must be uniform. However, in order to make the wall thickness of the plastic upper cover uniform, a cavity will exist inside the structure of the integrated handle 21. After the upper cover 13 and the integrated handle 21 are integrally injection molded, the interior of the integrated handle 21 is closed on all four sides and has limited space. During injection molding, the cavity cannot pass through the normal running position and inclined top mold parting. Therefore, in this embodiment, an inlay 22 is provided in the integrated handle 21, and the inlay 22 is used as a filler in the internal cavity of the integrated handle 21, so that the injection molding process of the upper cover 13 is uniform.

[0044] Combination Figures 6 to 9 , positioning posts 221 are provided at both ends of the inlay 22, and the two ends of the inlay 22 extend to fit the inner wall of the upper cover 13; the positioning posts 221 provided at both ends of the inlay 22 can play a guiding role when the inlay 22 is fixed on the mold of the upper cover 13; the inlay 22 can be made of a material with a melting point close to or higher than that of the upper cover 13, so that during the process of glue injection of the upper cover 13, only the surface of the inlay 22 is melted and connected with the material of the upper cover 13, rather than being completely melted and mixed with the material of the upper cover 13, resulting in failure to achieve the purpose of filling. The side wall of the inlay 22 is provided with a plurality of reinforcing ribs 222 arranged in parallel along the length direction, which can enhance the bending strength of the inlay 22. During injection molding, the plastic material in a molten state can be diverted to cover the periphery of the inlay 22 to obtain the shell of the integrated handle 21. The use of the inlay 22 makes the product molding more uniform and beautiful.

[0045] An inlay 22 is embedded inside the integrated handle 21 as a supporting filling structure of the integrated handle 21. On the one hand, it can ensure smooth injection when the integrated handle 21 and the upper cover 13 are integrally injection-molded, and will not cause thermal deformation, shrinkage, bubbles, shrinkage holes, etc. due to uneven wall thickness after plastic molding. On the other hand, it can also ensure that the transition part between the integrated handle 21 and the upper cover 13 is smooth when the integrated handle 21 and the upper cover 13 are integrally injection-molded.

[0046] In this embodiment, the integrated handle 21 , the upper cover 13 , and the inlay 22 are all made of plastic material. The front plate 11 and the lower cover 12 may also be made of plastic material.

[0047] The utility model provides an integrated handle 21 on the shell of the energy storage device, so that the product has higher integrity, stronger structural strength, more beautiful appearance and better user experience; and the integrated handle 21 is injection molded together with the upper cover 13, without disassembly, eliminating the steps of separate design and installation of the handle, saving cost and assembly time; in addition, the use of the inlay 22 reduces the difficulty of plastic molding in the manufacturing process of the integrated handle 21, and the inlay 22 structure plays a supporting and filling role, uniformizing the wall thickness of the plastic shell, and solving the problems of shrinkage and difficulty in molding of the plastic shell due to uneven wall thickness.

[0048] In other embodiments, the housing assembly of the energy storage device may also include a front housing and a rear housing, in which case the integrated handle may be integrally injection molded with the rear housing, for example, the integrated handle may be disposed at the rear side edge of the top surface of the rear housing, specifically, the integrated handle may be located in the middle of the rear side edge of the top surface of the rear housing. Alternatively, the housing assembly may also be composed of any other structure, as long as the integrated handle is integrally injection molded with any one of the structures at a corresponding appropriate position through an inlay as a support.
