Description

Technical Field

[0001] This utility model relates to the technical field of portable power banks, and in particular to a detachable portable power bank. Background Technology

[0002] A power bank, also known as a portable charger, is a portable charging device that integrates power supply and charging functions. It generally includes a casing, battery cells, circuit board, and input / output interfaces. Power banks can charge mobile devices such as mobile phones, tablets, headphones, and smartwatches anytime and anywhere, solving the problem of charging in places without fixed power outlets.

[0003] In the prior art, the outer shell of a power bank is often assembled from two half-shells. The half-shells are connected by interlocking snaps. The snap structure is located inside the half-shell and is integrally formed. After the outer shell is assembled, the snap structure cannot be contacted on the outer surface of the outer shell.

[0004] Therefore, the snap-fit ​​connection method used in conventional power banks makes it difficult to disassemble the casing after assembly, which limits users from replacing and maintaining the internal components of the power bank themselves. If the gap between the half-shells is pried open to forcibly disassemble the casing, the snap-fit ​​structure that is integrally formed with the other structures of the half-shells is easily broken, making it impossible to reassemble the casing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a detachable portable power bank to solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a detachable power bank, which includes a main shell, a cover plate, a battery cell, and a circuit board.

[0008] The outer shell body includes an integrally formed front shell plate, rear shell plate, bottom shell plate, and two side shell plates. The front shell plate, rear shell plate, bottom shell plate, and two side shell plates together form a receiving cavity. The top opening of the outer shell body corresponds to the receiving cavity. A first screw post is provided on the top of the rear shell plate, and a second screw post is provided on the top of each of the two side shell plates next to the front shell plate. The outer shell cover plate covers the top opening of the outer shell body, closing its receiving cavity. The outer shell cover plate has screw holes corresponding to the first and second screw posts for locking the outer shell cover plate to the outer shell body with screws. The battery cell is placed in the receiving cavity. The bottom surface of the outer shell cover plate is arc-shaped. The outer shell cover plate and the bottom shell plate are respectively raised to form arc edges. The battery cell abuts against the arc edges of the outer shell cover plate and the arc edges of the bottom shell plate, respectively. The circuit board is placed in the receiving cavity. A slot is provided on the bottom surface of the outer shell cover plate, and the top of the circuit board is embedded in the slot.

[0009] Preferably, a downwardly recessed mating groove is formed on the top edge of the side shell plate, the mating groove being located on the inner side of the side shell plate facing the receiving cavity, and a protruding edge extending downward from the edge of the outer shell cover plate that mates with the side shell plate, the protruding edge being embedded in the mating groove to define the position between the outer shell cover plate and the side shell plate.

[0010] Preferably, a limiting notch is provided on the top of the rear shell plate, the first screw post is disposed in the limiting notch, and the outer shell cover plate protrudes on one side corresponding to the rear shell plate to form a limiting block. The limiting block is embedded in the limiting notch to limit the position between the outer shell cover plate and the rear shell plate.

[0011] Preferably, the plane of the circuit board is parallel to the front shell, the length direction of the battery cell extends from the rear shell towards the front shell, and the length direction of the battery cell is perpendicular to the plane of the circuit board.

[0012] Preferably, a limiting strip is formed protruding on the side shell plate and extends in the vertical direction. The limiting strip of the side shell plate is adjacent to the front shell plate and is used to abut against the left and right edges of the circuit board.

[0013] Preferably, a cable holder is provided on the top of the outer casing, and a plug slot is provided in the cable holder. A charging cable is electrically connected to the circuit board.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0028] To avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not of great importance are omitted.

[0029] like Figure 1 and Figure 2As shown, this utility model embodiment provides a detachable power bank, which includes a housing body 1, a housing cover 2, a battery cell 3, and a circuit board 4.

[0030] Combination Figure 3 As shown, the outer shell body 1 includes an integrally formed front shell plate 11, rear shell plate 12, bottom shell plate 13, and two side shell plates 14. The front shell plate 11, rear shell plate 12, bottom shell plate 13, and two side shell plates 14 together form a receiving cavity 100. The outer shell body 1 has a top opening corresponding to the receiving cavity 100. A first screw post 121 is provided on the top of the rear shell plate 12, and a second screw post 141 is provided on the top of each of the two side shell plates 14 next to the front shell plate 11.

[0031] Combination Figure 4 As shown, the outer cover plate 2 is placed over the top opening of the outer shell body 1, sealing its receiving cavity 100. The outer cover plate 2 has three screw holes 210 corresponding to one first screw post 121 and two second screw posts 141, respectively, for screws to be screwed into the corresponding first screw post 121 and second screw post 141 through the screw holes 210, so as to lock the outer cover plate 2 onto the outer shell body 1.

[0032] In this embodiment, the outer shell body 1 is a plastic part, and the front shell plate 11, rear shell plate 12, bottom shell plate 13 and two side shell plates 14 are integrally formed structures. The front shell plate 11, rear shell plate 12, bottom shell plate 13 and two side shell plates 14 are connected according to the front-back, left-right and top-bottom orientation to form a receiving cavity 100. The screw post is a common protruding structure in plastic parts and is often used to fix it with screws.

[0033] The battery cell 3 is placed in the receiving cavity 100. The bottom surface of the outer cover plate 2, which is the side opposite to the receiving cavity 100, is arc-shaped. Arc edges 31 are raised on the bottom surface of the outer cover plate 2 and the bottom shell plate 13, respectively. The battery cell 3 abuts against the arc edges 31 of the outer cover plate 2 and the bottom shell plate 13, respectively. The upper and lower sides of the battery cell 3 are arc-shaped. Therefore, the arc edges 31 on the bottom surface of the outer cover plate 2 and the bottom shell plate 13 can fit the outer side surface of the battery cell 3 and fix it between the two.

[0034] The circuit board 4 is placed in the receiving cavity 100, and a slot 220 is provided on the bottom surface of the outer shell cover plate 2. The top of the circuit board 4 is embedded in the slot 220.

[0035] When the aforementioned detachable power bank needs to be disassembled for maintenance of its internal components, simply loosen the screws in the three screw holes 210 on the outer cover plate 2. The screws will then be pulled out from the first screw post 121 and the second screw post 141, thus releasing the lock between the outer cover plate 2 and the outer body 1. The battery cell 3 and circuit board 4 inside the housing cavity 100 can be easily maintained or removed and replaced through the top opening of the outer body 1. After the work is completed, the outer cover plate 2 is placed back on the top opening of the outer body 1, and the battery cell 3 is re-secured by the arc edge 31 on the outer cover plate 2 against it. At the same time, the top of the circuit board 4 is inserted back into the slot 220 and clamped and fixed by the slot 220, ensuring the stability of the battery cell 3 and circuit board 4 inside the housing cavity 100 after reinstallation and preventing loosening from affecting long-term normal use.

[0036] Specifically, a downwardly recessed mating groove 140 is formed on the top edge of the side shell plate 14. The mating groove 140 is located on the inner side of the side shell plate 14 facing the receiving cavity 100. The edge of the outer shell cover plate 2 that mates with the side shell plate 14 extends downward to form a protruding edge 21. The protruding edge 21 is embedded in the mating groove 140 to limit the position between the outer shell cover plate 2 and the side shell plate 14. The mating grooves 140 on the left and right side shell plates 14 are respectively embedded in the protruding edges 21 on the left and right sides of the outer shell cover plate 2, which restricts the movement of the outer shell cover plate 2 on the horizontal plane after it is placed on the outer shell body 1, thereby improving the stability of the installation of the outer shell cover plate 2.

[0037] Furthermore, a limiting notch 120 is formed on the top of the rear shell plate 12, and the first screw post 121 is disposed within the limiting notch 120. A limiting block 22 protrudes from one side of the outer shell cover plate 2 corresponding to the rear shell plate 12. The limiting block 22 is embedded in the limiting notch 120 to limit the position between the outer shell cover plate 2 and the rear shell plate 12. The cooperation between the limiting block 22 and the limiting notch 120 also restricts the movement of the outer shell cover plate 2 on the horizontal plane after it is placed on the outer shell body 1. Moreover, the limiting block 22 is sufficiently conspicuous to facilitate quick positioning of the outer shell cover plate 2 during user installation.

[0038] In addition to using the outer cover plate 2 to limit and fix the circuit board 4, the plane where the circuit board 4 is located is parallel to the front cover plate 11, the length direction of the battery cell 3 extends from the rear cover plate 12 toward the front cover plate 11, and the length direction of the battery cell 3 is perpendicular to the plane where the circuit board 4 is located.

[0039] Furthermore, a limiting strip 142 extending vertically protrudes from the side shell plate 14. The limiting strip 142 of the side shell plate 14 is located on the side adjacent to the front shell plate 11 and is used to abut against the left and right edges of the circuit board 4. The limiting strip 142 of the side shell plate 14 determines the installation position of the circuit board 4 by abutting against the circuit board 4. A limiting strip 142 extending vertically may also protrude from the bottom shell plate 13 to limit the bottom of the circuit board 4.

[0040] like Figure 1 As shown, a cable holder 23 is provided on the top of the outer casing 2, and a plug slot 230 is provided in the cable holder 23. A charging cable 41 is electrically connected to the circuit board 4. The charging cable 41 passes through the front casing 11 and extends to the outside of the receiving cavity 100. The plug 411 of the charging cable 41 is inserted into the plug slot 230 so that the charging cable 41 is wound into a loop. Before removing the outer casing 2, the plug 411 is first removed from the plug slot 230. A cable tie 412 is provided on the charging cable 41. The cable tie 412 is located between the plug slot 230 and the front casing 11. After the user removes the plug 411 of the charging cable 41 from the plug slot 230, the charging cable 41 can be used to power other devices without having to carry an extra cable. Moreover, the charging cable 41 wound into a loop can be used as a lifting rope, making this detachable power bank more portable.

[0041] Meanwhile, a clip 231 is also provided on the top of the outer cover plate 2. The clip 231 extends upward and then bends laterally back to cover the outer cover plate 2. The clip 231 can clamp the object inside by deformation. The clip 231 can be integrally set with the cable holder 23, which is also an integral molded structure of the outer cover plate 2. This makes it convenient for the detachable power bank to be clipped to backpack straps and clothing for easy carrying.
