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

[0002] With the continuous development of mobile communication technology and smart electronic devices, users' demand for portable power banks is growing. As a portable energy storage device, power banks have become an indispensable electronic product in modern life due to their advantages such as portability and ease of use, and are widely used in emergency charging scenarios for electronic products such as mobile phones and tablets.

[0003] Existing power banks typically include a casing, a battery assembly, and a data cable structure. The data cable can be fixed or retractable and is used to provide power to electronic devices. To improve the portability of power banks, some products (such as the power bank disclosed in utility model patent CN221669597U) have slots and retaining buckles on the surface of the casing. The data cable end is fixed in the slot, and the retaining buckle forms a lifting section, allowing users to hold the power bank conveniently.

[0004] However, in actual use, when the user lifts the power bank using the pull tab, there will be a hard contact between the data cable output end and the card slot. Especially when the power bank is swaying, the outer sheath of the connection between the data cable output end and the data cable body is prone to cracking due to stress concentration. This will affect the conductivity and overall lifespan of the data cable, reducing the reliability of the product and the user experience. Utility Model Content

[0039] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0040] like Figures 1-4 As shown, a power bank according to this utility model includes a shell 1 and a rubber ring 3.

[0041] The outer casing 1 has a slot 101 on its top for securing the data cable output end 21, and a through hole 102 on its right side for securing the data cable body 22. The slot 101 has an open right side, and a rubber ring 3 is provided inside the open side. A variable diameter part 23 is provided at the connection between the data cable output end 21 and the data cable body 22. The outer diameter of the variable diameter part 23 is smaller than the outer diameter of the data cable output end 21 but larger than the outer diameter of the data cable body 22. The rubber ring 3 is elastically fitted onto the variable diameter part 23 or the data cable body 22.

[0042] In this structure, the elasticity of rubber allows the rubber ring 3 to be elastically fitted onto the variable diameter section 23 or the data cable body 22. This structure enables the data cable output end 21 to be elastically fixed in the slot 101 via the rubber ring 3. When the user pulls up the lifting section formed by the data cable, especially when the power bank is swaying, the rubber ring 3 effectively disperses the force on the data cable, preventing the outer sheath from cracking due to hard contact between the data cable output end 21 and the slot 101. This significantly improves the product's durability and safety.

[0043] Furthermore, such as Figure 4As shown, elastic protrusions 1012 are fixed on the front and rear sides of the slot 101, wherein the elastic protrusions 1012 elastically abut against the outer surface of the data cable output end 21. These elastic protrusions 1012 not only provide appropriate frictional resistance when the data cable output end 21 is inserted into the slot 101, preventing accidental slippage of the data cable and improving product safety and user experience, but also, in conjunction with the rubber ring 3, provide elastic cushioning for the data cable output end 21, making the data cable less prone to damage.

[0044] In the above structure, the inner diameter of the rubber ring 3 is equal to the outer diameter of the data cable body 22, ensuring that the rubber ring 3 can fit tightly against the data cable body 22 or the data cable output end 21 to provide better buffer protection, further preventing the data cable from being damaged by repeated lifting, and enhancing the overall reliability and service life of the power bank.

[0045] In the above structure, the left side wall of the card slot 101 is set in an inclined shape, which makes it easier for the data cable output end 21 to be inserted into and removed from the card slot 101. This not only improves the convenience of use, but also reduces the wear and tear on the data cable during insertion and removal, and extends the service life of the data cable.

[0046] In the above structure, a mounting hole 1011 is provided on the groove wall of the open part on the right side of the slot 101, and a connecting post 31 is provided on the side of the rubber ring 3. Specifically, as shown in the figure... Figure 3 As shown, one mounting hole 1011 is provided on each of the front and rear side walls of the slot 101, and correspondingly, one connecting post 31 is provided on each of the front and rear sides of the rubber ring 3. The connecting post 31 is fixed in the mounting hole 1011. This structure ensures that the rubber ring 3 will not easily shift or fall off, thereby ensuring its effective buffer protection for the data cable output end 21 and enhancing the stability and durability of the product.

[0047] In the above structure, the left end of the data cable body 22 passes through the through hole 102, and an inner flange 221 and an outer flange 222 are provided on its left end. The inner flange 221 is located on the right side inside the outer casing 1; the outer flange 222 is located on the right side outside the outer casing 1; the shell on the right side of the outer casing 1 is sandwiched between the inner flange 221 and the outer flange 222.

[0048] This structure ensures a secure connection between the data cable and the outer casing 1, preventing the data cable from loosening or falling off during use, thus improving the reliability and safety of the product.

[0049] Furthermore, the right end of the through hole 102 is provided with a countersunk hole 1021 for accommodating the outer flange 222, such as... Figure 1As shown, by embedding the outer flange 222 into the countersunk hole 1021, and aligning the right end of the outer flange 222 with the right end of the outer shell 1 after embedding, the power bank not only appears cleaner and more aesthetically pleasing, but also further enhances the fixing effect between the data cable and the outer shell 1, reduces the shaking of the data cable during use, and improves the stability and durability of the product.

[0050] In the above structure, a U-shaped elastic plate 11 is fixed to the left end of the through hole 102, such as... Figure 2 As shown, the U-shaped elastic plate 11 is sleeved on the left end of the data cable body 22; the U-shaped elastic plate 11 is clamped between the inner flange 221 and the shell on the right side of the outer shell 1.

[0051] Among them, the U-shaped elastic plate 11 is a silicone plate or a rubber plate. Through this elastic structure, not only is the buffer protection of the data cable connection part enhanced, but it can also effectively absorb the stress brought by external tension, prevent the data cable from breaking or poor contact due to repeated bending or uneven force, and extend the service life of the data cable.

[0052] In the above structure, the cross-sections of both the data cable output end 21 and the data cable body 22 are oblong. This structure not only facilitates the force distribution during lifting but also improves the convenience and comfort of handheld operation.

[0053] The method of using the power bank according to this utility model is as follows:

[0054] When using the power bank, pry the data cable output end 21 out of the slot 101 and pull out the data cable body 22 until the rubber ring 3 is in the appropriate position. During the pulling process, hold the rubber ring 3 to prevent excessive deformation. After use, adjust the relative position of the rubber ring 3 and the data cable body 22 so that the rubber ring 3 is elastically fixed on the variable diameter part 23 or the data cable body 22. Then, re-insert the data cable output end 21 into the slot 101. After insertion, the data cable output end 21 is elastically fixed in the slot 101 by the elastic protrusion 1012. The middle part of the data cable body 22 forms a ring-shaped lifting part for the user to hold.

[0055] In actual use, the elastic fixing effect of the rubber ring 3, together with the slot 101, elastic protrusion 1012, U-shaped elastic plate 11 and other structures, effectively protects the data cable and improves the overall reliability of the product.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
