[0002] A power bank, also known as a portable charger or mobile power bank, is a portable charger that can be carried by an individual and can store electrical energy. It is mainly used to charge consumer electronic products such as handheld mobile devices. Its main components include: a battery used for energy storage, a circuit for stabilizing the output voltage, and most power banks come with a charger for charging the built-in battery.
[0003] Power banks are mainly used in outdoor environments without power supply, which means they are likely to be affected by unexpected situations during use. In existing technologies, the outer shell of a power bank is usually a wraparound shell that fits the shape of the internal battery, such as the shell disclosed in CN113675928A. Although this type of shell can provide protection against impacts, it is easy to deform and damage the internal components when the power bank shell is subjected to external torque, thus failing to provide protection and posing certain safety hazards.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content
[0005] To address the issue that existing power bank casings typically use a wraparound design that conforms to the shape of the battery, which provides some protection against impacts, but is prone to deformation and damage to internal components when subjected to external torque, thus failing to provide adequate protection and posing certain safety hazards, this invention proposes a torque-resistant power bank casing and a mobile power supply.

[0009] The cover panel is fitted onto the two bottom surfaces and engaged with the anti-torsion protrusion. The anti-torsion member is fastened to the corresponding edge of the cover panel.
[0010] A closure component is fitted and engaged with one end of the housing.
[0011] The anti-torsion power bank shell, wherein the anti-torsion component is fixedly mounted on the shell;

[0014] The anti-torsion component includes a first buckle plate and a second buckle plate arranged opposite each other at a predetermined distance, and a connecting plate fixedly connected to one end of the first buckle plate and the second buckle plate. The sides of the first buckle plate and the second buckle plate are bent toward the covering panel to form a second mounting groove. The edge of the covering panel and the housing are fastened in the second mounting groove.
[0015] The anti-torsion power bank casing, wherein the other end of the casing is closed;
[0016] The housing has several mounting holes at one end corresponding to the end where the closure is fitted.
[0017] The closure is provided with an elastic latch adapted to the mounting hole; and / or, the closure is provided with a screw adapted to the mounting hole.
[0018] The anti-torsion power bank shell has a plurality of positioning holes through the cover panel, the positioning holes corresponding to the positions of the plurality of anti-torsion protrusions, and the anti-torsion protrusions penetrating and fitting into the positioning holes.

[0024] The beneficial effects of this utility model are as follows: By setting a number of anti-torsion protrusions that engage with the cover panel and setting an anti-torsion component on the shell that engages with the cover panel, when the power bank shell is subjected to torque, the cover panel pulls on the number of anti-torsion protrusions during the shell deformation process to limit the deformation range of the shell. At the same time, the anti-torsion component limits the position of the cover panel to further reduce the deformation, which can avoid damage to internal components caused by excessive deformation of the shell and reduce safety hazards caused by accidents during the use of the power bank.

[0035] Power banks are mainly used in outdoor environments without power supply, which means they are likely to be affected by unexpected situations during use. In existing technologies, the outer shell of a power bank is usually a wraparound shell that fits the shape of the internal battery, such as the shell disclosed in CN113675928A. Although this type of shell can provide protection against impacts, it is easy to deform and damage the internal components when the power bank shell is subjected to external torque, thus failing to provide protection and posing certain safety hazards.
[0036] In view of the above-mentioned problems in the prior art, the present invention provides a torsion-resistant power bank shell, such as... Figure 1 and Figure 2 As shown, the anti-torsion power bank casing includes: a shell 100, with a plurality of anti-torsion protrusions 110 respectively provided on the opposite bottom surfaces of the shell 100, and anti-torsion members 200 respectively provided on the opposite sides of the corresponding bottom sides of the shell 100; a cover panel 300, with two cover panels 300 respectively fitted onto the two bottom surfaces and engaged with the anti-torsion protrusions 110, and the anti-torsion members 200 fastened to the corresponding edges of the cover panels 300; and a closure member 400, which is sleeved and engaged with one end of the shell 100.
[0037] This utility model provides several anti-torsion protrusions 110 that engage with the cover panel 300, and an anti-torsion component 200 that engages with the cover panel 300 on the housing 100. When the power bank housing is subjected to torque, the cover panel 300 pulls on the several anti-torsion protrusions 110 during the deformation of the housing 100, thereby limiting the deformation range of the housing 100. At the same time, the anti-torsion component 200 restricts the position of the cover panel 300 to further reduce the deformation. This can prevent damage to internal components caused by excessive deformation of the housing 100 and reduce safety hazards caused by accidents during the use of the power bank.
[0038] In the above embodiments, such as Figure 1 and Figure 2 As shown, the main body of the anti-torsion power bank shell of this utility model consists of a shell 100, a cover panel 300, and a sealing member 400. The shell 100 is made of plastic or lightweight metal material and is approximately rectangular or cubic in shape. For ease of description, in this embodiment, the two sides with the largest area of the shell 100 are referred to as the bottom surface. The two bottom surfaces have the same structure and are provided with several anti-torsion protrusions 110 that protrude outward from the shell 100. In addition, anti-torsion members 200 are respectively provided on the two opposite sides of the two bottom surfaces of the shell 100. The anti-torsion members 200 are used to fix the cover panel 300.
[0039] The length and width of the cover panel 300 are adapted to the aforementioned bottom surface. During actual installation, it is fitted onto the two bottom surfaces and engaged with the aforementioned anti-torsion protrusions 110. On the one hand, the anti-torsion protrusions 110 position the cover panel 300 during installation. On the other hand, when the housing 100 is subjected to torque, the engagement with the anti-torsion protrusions 110 limits further deformation of the housing 100, thereby reducing the deformation of the power bank housing under torque and lowering the probability of damage to the internal functional components of the housing 100. In this embodiment, the side of the cover panel 300 is fastened by anti-torsion members 200 provided on the housing 100. On the one hand, the anti-torsion members 200 improve the structural strength of the housing 100, and on the other hand, the anti-torsion members 200 lock the position of the cover panel 300, thereby providing a reverse pulling effect when the housing 100 deforms.
[0040] The closure 400 is used to close the opening of the housing 100. In a specific embodiment, the housing 100 of the power bank is usually closed at one end to improve the integrity of the housing 100. Therefore, after the functional components are installed inside the housing 100, the closure 400 is used to close the opening of the housing 100. This can ensure the structural stability of the assembled power bank and also allow the necessary circuit structure to be set up through the closure 400, making it convenient for users to use or maintain.
[0041] Based on the above embodiments, the anti-torsion component 200 of the anti-torsion power bank shell of this utility model has multiple configuration methods to meet the different structural requirements of different models of power banks.
[0042] Specifically, in the first embodiment of this utility model, as Figure 3 As shown, the anti-torsion member 200 is fixedly mounted on the housing 100. The anti-torsion member 200 is actually an extension structure protruding from the side of the housing 100 toward the bottom surface. The side of the anti-torsion member 200 is bent toward the cover panel 300. This bent structure forms a first mounting groove 210 with the bottom surface of the housing 100. The width of the first mounting groove 210 should be adapted to the thickness of the cover panel 300. During actual installation, the edge of the cover panel 300 is fastened in the first mounting groove 210, thereby locking the horizontal displacement of the cover panel 300 through several anti-torsion protrusions 110, and locking the vertical displacement of the cover panel 300 through the anti-torsion members 200 located on both sides of the housing 100, thereby achieving the effect of stable assembly of the cover panel 300.
[0043] In this embodiment, the advantage of this design is that it can minimize the weight of the casing 100, thereby making the produced power bank more portable.
[0044] In the second embodiment of this utility model, as Figure 4 As shown, the anti-torsion component 200 is detachably mounted on the housing 100. The anti-torsion component 200 and the housing 100 are independent components. Specifically, the anti-torsion component 200 includes a first buckle plate 231 and a second buckle plate 232 arranged at a predetermined distance from each other, and a connecting plate 233 fixedly connected to one end of the first buckle plate 231 and the second buckle plate 232. The shape of the connecting plate 233 is adapted to the end shape of the housing 100, and the first buckle plate 231 and the second buckle plate 232 are respectively adapted to the side shapes of the housing 100. During assembly, it can be inserted and removed from the outside of the housing 100. The sides of the first buckle plate 231 and the second buckle plate 232 are bent toward the cover panel 300. This bending structure forms the second mounting groove 220. When the cover panel 300 is assembled on the bottom surface of the housing 100, the second mounting groove 220 can be fastened to the edge of the cover panel 300 after the anti-torsion member 200 is installed. In actual installation, the horizontal displacement of the cover panel 300 is locked by a number of anti-torsion protrusions 110, and the vertical displacement of the cover panel 300 is locked by the anti-torsion members 200 located on both sides of the housing 100, so as to achieve the effect of stable assembly of the cover panel 300.
[0045] In this embodiment, the advantage of this arrangement is that it is easier to assemble than the first embodiment, thereby improving production efficiency.
[0046] In the above embodiments, the cover panel 300 is preferably made of carbon fiber material. A carbon fiber panel is a panel composed of carbon fiber and resin, which has excellent low deformation characteristics under tension and compression. The carbon fiber panel has high strength in all four directions of the plane and will maintain its original shape as much as possible, which makes it widely used in many fields. In this embodiment, by setting the cover panel 300 as a carbon fiber cover panel 300, when the shell 100 is deformed by torsion, a number of anti-torsion protrusions 110 apply tension to the cover panel 300. Due to the excellent low deformation characteristics of the cover panel 300 under tension, it can effectively resist the tensile force and thus maintain a relatively stable shape. This enables the overall structure of the power bank to withstand greater torsion. On the other hand, the carbon fiber material has a lighter weight while ensuring strength, which can effectively reduce the overall weight and thickness of the power bank and is conducive to the lightweight design of the power bank.
[0047] In one specific embodiment of this utility model, such as Figure 2 As shown, the aforementioned cover panel 300 is provided with a plurality of positioning holes 310. Correspondingly, the height of the plurality of anti-torsion protrusions 110 provided on the housing 100 is adapted to the thickness of the cover panel 300. When installed, the positions of the plurality of positioning holes 310 and the plurality of anti-torsion protrusions 110 correspond, and the plurality of anti-torsion protrusions 110 are provided through and fitted in the positioning holes 310. The advantage of this arrangement is that it can improve the degree of combination between the cover panel 300 and the anti-torsion protrusions 110, thereby achieving a more stable traction effect.
[0048] In another possible embodiment of this utility model, such as Figure 3 As shown, the center of the bottom surface of the housing 100 is hollowed out to further reduce the overall weight of the housing 100. During assembly, this hollowed-out area allows assemblers to easily observe whether the functional structures inside the housing 100 are accurately installed in their intended positions. Furthermore, the hollowed-out area also provides mounting positions for shock-absorbing and protective pads. In this embodiment, the aforementioned anti-torsional protrusions 110 are arranged along the edge of the bottom surface. In one specific embodiment, as shown... Figure 3 As shown, six anti-torsion protrusions 110 are symmetrically arranged on the two bottom surfaces of the housing 100 along the longitudinal axis of the housing 100, and there are a total of 12 anti-torsion protrusions 110 on the top and bottom of the housing 100. During the specific installation, adhesive can also be applied to the side of the cover panel 300 facing the housing 100 to further prevent the cover panel 300 from falling off when subjected to force.
[0049] In another possible embodiment of this utility model, such as Figure 3As shown, in a specific configuration, one end of the housing 100 is fitted and engaged with the closure member 400, while the other end is closed, making the structure of the housing 100 more stable. When the closure member 400 is fitted and engaged with the housing 100, the closure member 400 can provide support to the inner side of the end of the housing 100, thereby preventing the housing 100 from deforming due to force. In one specific embodiment, a plurality of mounting holes 120 are also provided on the end of the housing 100 corresponding to the fitting of the closure member 400. The mounting holes 120 are hollowed out, and the closure member 400 is provided with elastic tenons 410 that are adapted to the mounting holes 120. The elastic tenons 410 can be engaged and fixed with the mounting holes 120, which not only achieves a fixed combination but also facilitates subsequent maintenance. In another specific embodiment, screws 420 adapted to the mounting holes 120 can be provided on the closure member 400. After the closure member 400 and the housing 100 are fitted together, the mounting screws 420 can be used to securely install the closure member 400 and the housing 100. In other specific embodiments, the mounting holes 120 can be configured with different types, and can be further fixed by mounting screws 420 while being combined with the housing 100 by the elastic tenon 410, thereby further improving the deformation resistance of the housing 100.
[0050] In another possible embodiment of this utility model, such as Figure 3 As shown, a number of connecting ribs 130 are also provided inside the shell 100. The connecting ribs 130 are specifically plate-shaped members. The two ends of the connecting ribs 130 are fixedly connected to the two bottom surfaces respectively, thereby limiting the distance between the two bottom surfaces of the shell 100 and strengthening the structure in the thickness direction of the shell 100, which can further improve the structural stability of the shell 100.
[0051] In addition, such as Figure 3 As shown, a number of guide ribs 140 are also provided inside the housing 100. Since one end of the housing 100 is closed, it is difficult for installers to observe the positioning of the functional components when installing them from the open end of the housing 100. Therefore, by providing guide ribs 140 inside the housing 100, the functional components can be guided to the predetermined area. One end of the guide rib 140 is inclined, with the inclined surface facing the opening of the housing 100. Thus, the inclined surface of the guide rib 140 can guide the functional components.
[0052] Based on the above embodiments, the actual installation process of the anti-torsion power bank shell of this utility model is as follows:
[0053] like Figure 3 As shown, the closure 400 is installed at one end of the opening of the housing 100 and fixed by the elastic latch 410 or screw 420.
[0054] like Figure 1As shown, the cover panel 300 is installed on the two bottom surfaces of the housing 100, and the positioning hole 310 on the cover panel 300 is combined with the anti-torsion protrusion 110 at the corresponding position. The two sides of the cover panel 300 are then fastened to the anti-torsion members 200 on both sides of the housing 100, thus completing the assembly.
[0055] In actual use, power banks may experience the following when subjected to external torque: Figure 5 and Figure 6 In both cases, the deformation tendency of the housing 100 will cause several anti-torsion protrusions 110 to shift. Due to the carbon fiber cover panel 300, the positioning holes 310 on the cover panel 300 can realize the function of resetting and pulling several anti-torsion protrusions 110. Thus, the low deformation characteristics of the cover panel 300 itself resist the torsional force on the housing 100, thereby reducing the degree of deformation of the housing 100 and increasing the torsional resistance of the housing 100. This solves the problem in the prior art that the power bank shell is prone to deformation when subjected to external torsion, which can easily cause damage to the internal components of the power bank, and improves the torsional resistance of the power bank shell.
[0056] Based on the above embodiments, this utility model also provides a portable power bank, which includes the anti-torsion power bank shell described in the above embodiments. The anti-torsion power bank shell includes: a shell, on which a plurality of anti-torsion protrusions are respectively provided on opposite bottom surfaces, and anti-torsion members are respectively provided on opposite sides of the corresponding bottom sides of the shell; a cover panel, two cover panels are respectively fitted onto the two bottom surfaces and engaged with the anti-torsion protrusions, and the anti-torsion members are fastened to the corresponding edges of the cover panels; and a closure member, which is sleeved and engaged with one end of the shell. This utility model, by providing a plurality of anti-torsion protrusions that engage with the cover panels and providing anti-torsion members on the shell that engage with the cover panels, when the power bank shell is subjected to torsion, the cover panels pull on the plurality of anti-torsion protrusions during the deformation of the shell to limit the deformation range of the shell. At the same time, the anti-torsion members limit the position of the cover panels to further reduce the deformation, which can avoid damage to internal components caused by excessive deformation of the shell and reduce safety hazards caused by accidents during the use of the power bank.
[0057] In summary, this utility model provides a torsion-resistant power bank shell and a power bank. The torsion-resistant power bank shell includes: a shell with several torsion-resistant protrusions on its opposite bottom surfaces and torsion-resistant components on opposite sides of the corresponding bottom surfaces; a cover panel, with two cover panels fitted onto the two bottom surfaces and engaging with the torsion-resistant protrusions, and torsion-resistant components fastening to the corresponding edges of the cover panels; and a closure, which is fitted and engaged with one end of the shell. This utility model, by providing several torsion-resistant protrusions engaging with the cover panels and torsion-resistant components on the shell engaging with the cover panels, ensures that when the power bank shell is subjected to torsion, the cover panels pull on the torsion-resistant protrusions during shell deformation, limiting the deformation range. Simultaneously, the torsion-resistant components limit the position of the cover panels to further reduce deformation, thus preventing damage to internal components due to excessive shell deformation and reducing safety hazards caused by unexpected situations during power bank use.
[0058] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
