Description

Technical Field

[0001] This utility model relates to the field of power bank technology, specifically a power bank with a retractable cable structure. Background Technology

[0002] A 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. A power bank is mainly composed of a shell, a circuit board and battery cells. Some power banks also have some personalized functional system settings.

[0003] However, traditional power banks mostly have fixed charging cables that cannot be extended or retracted. To overcome this defect, existing technology (Chinese patent application number 202220836318.3, application date 2022-04-12) provides a power bank with a retractable cable. It uses a storage component to store the charging cable, a storage tray to store the charging cable, and a limiting component to limit the rotation of the storage tray. This provides a power bank with a retractable cable that is convenient for storing the charging cable and allows the charging cable to extend or retract. However, the retractable cable structure of the above power bank is relatively simple, using only a single metal spring to achieve the extension and retraction of the charging cable. Not only is the single metal spring prone to deformation after long-term use, affecting the extension and retraction effect, but the function is also relatively simple, resulting in a poor user experience.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing equipment. Therefore, we have proposed a power bank with a retractable cable structure that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a power bank with a retractable cable structure, so as to solve the problem that the retractable cable structure of the power bank mentioned in the background art is relatively simple, and the charging cable is retracted and stored by only a single metal spring. Not only is the single metal spring prone to deformation after long-term use, which affects the retraction effect, but the function is also relatively simple and the user experience is not good.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power bank with a telescopic cable structure, comprising a shell, a top cover covering the top of the shell, and a charging head and a charging cable on one side of the shell; a storage tray is fixedly installed inside the shell, and the end of the charging cable is movably connected to the inside of the storage tray via a telescopic component; the telescopic component includes a central tube fixedly connected to the inside of the storage tray, a lifting rod slidably connected to the inner side of the central tube, and the top of the lifting rod extending to the outer side of the top cover; four movable rods are slidably connected around the inside of the storage tray, and the charging cable is wound around the outer side of the four movable rods; a spring is fixedly connected between the movable rod and the outer wall of the central tube; a connecting line is fixedly connected between the bottom of the movable rod and the lifting rod; and a fixing clip and a handle rope are sequentially fixedly connected to the top of the central tube.

[0007] Preferably, the sidewall of the outer shell is formed with a groove, and the charging head is stored inside it to achieve daily storage and protection of the charging head.

[0008] Preferably, a power display panel is fixedly installed on the inner wall of the top of the outer casing, and the position of the top cover corresponding to the power display panel is transparent, so as to facilitate the user to check the power of the power bank and charge the power bank in time.

[0009] Preferably, the top inner wall of the top cover is formed with a positioning frame that matches the outer contour of the storage tray, and the storage tray is snapped into the inner side of the positioning frame to ensure that the storage tray remains stable and still when the charging head and charging cable are pulled out from the storage tray for use.

[0010] Preferably, the inner walls of the top and bottom of the storage tray are provided with sliding grooves for the sliding rod to slide. The outer wall of the central tube is fixedly connected with four evenly distributed guide rods, and the sliding rod is slidably connected to the outside of the guide rods. The guide rods are respectively located inside the corresponding springs.

[0011] Preferably, the fixing clip is fixed in position by a snap-fit ​​assembly. The snap-fit ​​assembly includes a protruding ring formed on the top of the top cover. Two rotating rods are rotatably connected to one top end of the protruding ring, and a torsion spring is fixedly connected between the rotating rod and the protruding ring. A snap-fit ​​piece is fixedly connected to the outer wall of the rotating rod. Slots are provided on both sides of the fixing clip, and two snap-fit ​​pieces are symmetrically snapped into the inner side of the slots.

[0012] Preferably, an unlocking block is fixedly connected to the top of the rotating rod, and the outer wall of the unlocking block is formed with a toggle part, and the two toggle parts are in a figure-eight shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This power bank with a telescopic cable structure, by setting a telescopic component, uses four springs instead of a single metal spring in the prior art to realize the elastic extension and retraction of the charging cable, which can effectively extend the service life of the charging cable extension and retraction and ensure the extension and retraction effect. In addition, by setting a handle rope, it is convenient for users to carry the power bank by hand for hooking or carrying. Just pull the handle rope upward to drive the four moving rods to retract inward, and the charging cable can be pulled out for charging. This enriches the use function of the power bank and improves the user experience. The specific contents are as follows: (1) By setting a telescopic component, four springs push the moving rods outward to make the four moving rods expand outward and retract the charging cable inside the storage tray. When charging, just pull the handle rope upward to make the four moving rods retract inward, and the charging cable and charging head can be pulled out for charging. The above structure is reasonable and ingenious. By using four springs instead of a single metal spring in the prior art, the elastic extension and retraction of the charging cable can be realized, which can effectively extend the service life of the charging cable extension and retraction and ensure the extension and retraction effect.

[0014] (2) By opening a sliding groove, the four moving rods are limited to slide inside the storage tray, and four guide rods are provided on the inner side of the spring to ensure that the moving rods can move in a straight line when pulled, thereby ensuring that the spring is always compressed in a straight line, thus avoiding the problem of reduced elasticity caused by skewed deformation.

[0015] (3) The addition of a handle strap makes it easier for users to hook or carry the power bank, thus enriching the power bank's functionality and enhancing the user experience.

[0016] (4) The position of the fixing piece is fixed by the snap-fit ​​component. By using the snap-fit ​​of the snap-fit ​​piece and the torque of the torsion spring, the fixing piece can be snapped and limited to the inside of the convex ring, thereby locking the telescopic component and improving the stability of the user carrying the power bank by hand with the handle rope.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a power bank with a retractable cable structure includes a shell 1, a top cover 2 covering the top of the shell 1, and a charging head 3 and a charging cable 4 provided on one side of the shell 1. The side wall of the shell 1 is formed with a groove, and the charging head 3 is stored inside it to achieve daily storage and protection of the charging head 3. A power display board 6 is fixedly installed on the inner wall of the top of the shell 1, and the position corresponding to the top cover 2 and the power display board 6 is transparent, so as to facilitate the user to check the power of the power bank and charge the power bank in time.

[0026] A storage tray 5 is fixedly installed inside the outer casing 1, and the end of the charging cable 4 is movably connected to the inside of the storage tray 5 through a telescopic component. The telescopic component includes a central tube 8 fixedly connected inside the storage tray 5. A lifting rod 9 is slidably connected to the inner side of the central tube 8, and the top end of the lifting rod 9 extends to the outer side of the top cover 2. Four moving rods 10 are slidably connected around the inside of the storage tray 5, and the charging cable 4 is wrapped around the outer side of the four moving rods 10. A spring 12 is fixedly connected between the moving rod 10 and the outer wall of the central tube 8. A connecting line 13 is fixedly connected between the moving rod 10 and the bottom of the lifting rod 9. A fixing clip 14 and a handle rope 15 are fixedly connected to the top end of the central tube 8 in sequence.

[0027] By setting up a telescopic component, four springs 12 push the moving rod 10 outward, causing the four moving rods 10 to expand outward and retract the charging cable 4 inside the storage tray 5. When charging, simply pull the fixing clip 14 and the lifting rod 9 upward with the handle rope 15. The connecting line 13 is pulled simultaneously, and the four moving rods 10 are pulled inward, causing the moving rods 10 to retract. The springs 12 are compressed, and the charging cable 4 and charging head 3 can then be pulled out for charging. The above structure is reasonable and ingenious. By using four springs 12 instead of a single metal spring in the prior art, the elastic extension and retraction of the charging cable 4 can be achieved, which can effectively extend the service life of the extension and retraction of the charging cable 4 and ensure the extension and retraction effect. In addition, the handle rope 15 makes it easy for users to hook or carry the power bank, thereby enriching the use function of the power bank and improving the user experience.

[0028] Meanwhile, the inner walls of the top and bottom of the storage tray 5 are provided with sliding grooves for the sliding rod 10 to slide. Four evenly distributed guide rods 11 are fixedly connected to the outer wall of the central tube 8, and the sliding rod 10 is slidably connected to the outside of the guide rods 11. The guide rods 11 are respectively located inside the corresponding springs 12. The above structure ensures that the sliding rod 10 can move stably in a straight line when it is pulled, thereby ensuring that the spring 12 is always compressed in a straight line, thus avoiding the problem of reduced elasticity caused by skewed deformation.

[0029] In addition, the top inner wall of the top cover 2 is formed with a positioning frame 7 that matches the outer contour of the storage tray 5, and the storage tray 5 is snapped into the inside of the positioning frame 7 to ensure that the storage tray 5 can always remain stable when the charging head 3 and the charging cable 4 are pulled out from the storage tray 5 for use.

[0030] Example 2: Based on Example 1, the fixing clip 14 is fixed in position by a snap-fit ​​assembly. The snap-fit ​​assembly includes a protruding ring 16 formed on the top of the top cover 2. Two rotating rods 17 are rotatably connected to one end of the top of the protruding ring 16, and a torsion spring 19 is fixedly connected between the rotating rods 17 and the protruding ring 16. A snap-fit ​​piece 18 is fixedly connected to the outer wall of the rotating rod 17. The fixing clip 14 has slots on both sides, and the two snap-fit ​​pieces 18 are symmetrically snapped into the inner side of the slots. By snapping the snap-fit ​​pieces 18 and fixing the torsion of the torsion spring 19, the fixing clip 14 can be snapped and limited to the inner side of the protruding ring 16, thereby locking the telescopic component and improving the stability of the user carrying the power bank by hand with the handle rope 15.

[0031] Furthermore, an unlocking block 20 is fixedly connected to the top of the rotating rod 17, and the outer wall of the unlocking block 20 is formed with a toggle part. The two toggle parts are in a figure-eight shape. By simply pinching the toggle parts of the two unlocking blocks 20 with two fingers to bring them close together, the rotating rod 17 can drive the two snap-fit ​​pieces 18 to open and disengage from the slot of the fixing piece 14, so that the fixing piece 14 and the handle rope 15 can move flexibly to realize the extension and retraction of the charging cable 4, thereby facilitating use.
