Description

Technical Field

[0001] This utility model relates to the field of power bank technology, and in particular to a power bank shell structure. Background Technology

[0002] As a portable energy storage device, the casing of a power bank needs to balance the protection of internal components, ease of assembly, and safety of use. Traditional power bank casings mostly adopt a one-piece design, usually consisting of an upper shell and a battery bracket directly spliced ​​together with screws or clips.

[0003] Specifically, in the existing assembly process, key components such as the top cover and brackets generally need to be individually positioned and installed inside the housing. Operators need to adjust the position of each component one by one to ensure precise fit. This not only increases the complexity of the assembly steps, but also easily leads to poor assembly due to positioning deviations, affecting product consistency. Moreover, in the process of mass production, the multi-step positioning operation significantly prolongs the assembly cycle of a single product and reduces the overall production efficiency.

[0004] Based on this, in order to further improve the ease of assembly and efficiency of existing power bank structures, we propose a power bank shell structure. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a power bank casing structure.

The upper bracket stops below the upper cover, the circuit board frame is connected to the lower bracket, and the lower cover and the circuit board frame are detachably connected. The housing has an internal connection structure that connects the top cover and the circuit board frame.

[0007] Furthermore, the connection structure includes a plurality of connection protrusions formed inside the housing, wherein connection holes are formed in the connection protrusions extending to both ends therethrough, and the top cover is connected with fasteners that sequentially pass through the connection holes and the circuit board frame.

[0008] Furthermore, the outer side of the top cover has an outwardly flared edge, which stops on the upper side of the housing, and the bottom of the top cover stops above the plurality of connecting protrusions.

[0009] Furthermore, the upper end of the circuit board frame abuts against the lower part of the plurality of connecting protrusions, and a plurality of connecting positions are provided on the outer side of the circuit board frame, and the fastener is connected to the connecting positions.

[0010] Furthermore, multiple connecting arms are formed below the lower support, and plug-in arms are formed at the bottom of the connecting arms. The end face of the circuit board frame is provided with a locking hole for insertion of the plug-in arm, and the bottom end of the plug-in arm stops above the circuit board frame.

[0011] Furthermore, the bottom outer periphery of the circuit board frame is also formed with several slots, the upper part of the lower cover is formed with multiple clip arms, the outer side of the clip arms is formed with clip protrusions, the multiple clip arms are inserted into the lower inner side of the circuit board frame, and the clip protrusions and the slots are engaged.

The battery is installed between the upper bracket 41 and the lower bracket 42. In this embodiment, the battery can be set as an 18650 battery. Mounting slots are provided on the opposite surfaces of the upper bracket 41 and the lower bracket 42, and the battery is accommodated in the two opposite mounting slots. The upper bracket 41 stops below the upper cover 2, the circuit board frame 43 is connected to the lower bracket 42, and the lower cover 3 and the circuit board frame 43 are detachably connected. The housing 1 has a connection structure 11 inside that connects the top cover 2 and the circuit board frame 43.

[0019] In some embodiments, the connection structure 11 of the present invention includes a plurality of connection protrusions 111 formed inside the housing 1, and connection holes 112 extending through both ends of the connection protrusions 111 are formed in the connection protrusions 111. The upper cover 2 is connected with fasteners that pass through the connection holes 112 and the circuit board frame 43 in sequence.

[0020] Specifically, in this embodiment, the fastener is a bolt. The bolt is inserted from the top of the upper cover 2 and passes through the connecting protrusion 111 in sequence. Finally, it is threaded to the circuit board frame 43. At this time, the upper bracket 41 and the lower bracket 42 inside are supported by the battery, thus completing the overall assembly.

[0021] Based on the above embodiments, the outer side of the upper cover 2 in this utility model has an outwardly expanding edge 21, the outwardly expanding edge 21 stops on the upper side of the housing 1, and the bottom of the upper cover 2 stops above the plurality of connecting protrusions 111.

[0022] Furthermore, in this embodiment, the upper end of the circuit board frame 43 abuts against the lower part of the plurality of connecting protrusions 111, and a plurality of connecting positions 431 are provided on the outer side of the circuit board frame 43, and the fastener is connected to the connecting positions 431.

[0023] Specifically, in this embodiment, three connecting protrusions 111 are distributed along the inner circumference of the housing 1. Similarly, three connecting positions 431 are also provided. In this embodiment, the connecting positions 431 are provided as slots. The slots abut against the lower part of the connecting protrusions 111 and are provided with threaded holes. The threaded holes are threadedly connected to the fasteners to achieve overall assembly and fixation.

[0024] In other words, during assembly, the circuit board frame 43 is first placed against the lower end of the multiple connecting protrusions 111 pre-set on the inner wall of the housing 1 to complete the initial positioning of the circuit board frame 43. Subsequently, the battery is installed between the upper bracket 41 and the lower bracket 42, then placed inside the housing 1 and supported by the circuit board bracket 43. Then, the upper cover 2 is inserted from the upper opening of the housing 1 and positioned above the upper bracket 41. During assembly, bolts are used as fasteners. The bolts pass through the top cover 2 and the connecting protrusion 111 in sequence and are threaded to the circuit board frame 43. The tension of the bolts acts between the top cover 2 and the circuit board frame 43, and the axial limiting effect of the outwardly expanding edge on the upper end of the housing 1 is used to achieve a stable locking and fixing between the components.

[0025] In some embodiments, a plurality of connecting arms 421 are formed below the lower support 42 of the present invention, and a plug-in arm 422 is formed at the bottom of the connecting arm 421. The end face of the circuit board frame 43 is provided with a locking hole 432 for insertion into the plug arm 422, and the bottom end of the plug arm 422 is stopped above the circuit board frame 43.

[0026] In this embodiment, by using multiple plug-in arms 422 and locking holes 432 for plug-in connection, circumferential locking and positioning between the circuit board frame 43 and the plug-in arms 422 can be achieved. At the same time, with the help of the connecting arm 421 for support, the lower bracket 42 can be supported and the lower bracket 42 and the circuit board frame 43 can be spaced apart to facilitate the subsequent installation and routing of the circuit board.

[0027] Optionally, in this embodiment, the bottom outer periphery of the circuit board frame 43 is also formed with a plurality of slots 433, the upper part of the lower cover 3 is formed with a plurality of locking arms 31, the outer side of the locking arms 31 is formed with locking protrusions 32, the plurality of locking arms 31 are inserted into the lower inner side of the circuit board frame 43, and the locking protrusions 32 and the slots 433 are engaged.

[0028] In other words, the lower cover 3 described in this embodiment is connected and fixed to the circuit board frame 43 by a snap-fit ​​method, so as to fix the lower cover 3 inside the entire housing 1. In specific installation, the lower cover 3 can be directly inserted into the housing 1, and the snap-fit ​​arm 31, snap-fit ​​protrusion 32 and snap-fit ​​groove 433 on the lower cover 3 are engaged, so as to complete the installation and positioning of the lower cover 3.

[0029] Preferably, in this embodiment, both the upper bracket 41 and the lower bracket 42 are triangular in structure, and both the upper bracket 41 and the lower bracket 42 have positioning openings 44 formed on their sides to accommodate the connecting protrusion 111. Through the design of the positioning openings 44, the upper bracket 41 and the lower bracket 42 can be circumferentially positioned and locked. Thus, when fasteners are connected, the upper cover 2, the upper bracket 41, the lower bracket 42 and the circuit board frame 43 can be positioned once, which greatly improves the convenience and reliability of installation.

[0030] It should be noted that the shell 1 in this embodiment has a circular structure, and a heat dissipation part 12 is formed on the outer periphery of the shell 1. A protective sleeve 5 is also fitted on the outer side of the shell 1. Specifically, the heat dissipation part 12 in this embodiment is set as a heat dissipation fin structure. The shell 1 in this embodiment is preferably set as a cylindrical structure and made of aluminum, which can improve the internal heat dissipation effect. In addition, by adopting the design of the protective sleeve 5, effective anti-collision protection and anti-slip can be achieved for the entire shell 1, so as to improve the safety of this power bank.

[0031] In summary, by adopting a modular assembly structure for the upper cover 2, lower cover 3, upper bracket 41, lower bracket 42, and circuit board frame 43, the present invention allows each component to be installed independently and then integrated into the housing 1. This design avoids the complexity of the traditional integral housing requiring simultaneous positioning of multiple components, making the assembly process clearer, the operation simpler, significantly shortening the assembly time, and improving production efficiency.
