Description

TECHNICAL FIELD

[0001] The utility model relates to a charging device, in particular to a portable power bank. BACKGROUND

[0002] With the rapid development of mobile communication, various mobile intelligent devices are gradually becoming indispensable tools in people's daily life, and in order to meet the needs of people when going out for mobile phone charging, the power bank has become one of the mainstream means for charging intelligent devices outdoors.

[0003] Please refer to Figure 1 It is a common power bank with a charging line at present, which comprises a power bank body 1, a charging head 2 and a charging line 3, the charging line 3 is connected between the power bank body 1 and the charging head 2, a recess 4 is arranged on the shell of the power bank body 1, the charging head 2 and the charging line 3 can be embedded in the recess 4 to form a whole box structure with the power bank body 1, when charging is needed, the charging head 2 is taken out from the recess 4 and connected to the intelligent device. Such design makes the charging line 3 and the charging head 2 occupy part of the volume space of the power bank body 1, resulting in that the power bank body 1 is relatively large in volume, and at the same time, the power bank body 1 cannot place a larger battery to improve the capacity of the power bank. UTILITY MODEL CONTENTS

[0004] Therefore, the utility model aims at providing a portable power bank, which can make the charging line of the power bank be bent to form a ring-shaped portable structure, so as to facilitate the user to carry the power bank.

[0005] A portable power bank comprises a charging unit, a charging line, a charging head and a card seat, the charging head is electrically connected with the charging unit through the charging line, the charging line extends out of the charging unit, the card seat is directly or indirectly connected to the charging unit, the card seat comprises a partition plate, a first protrusion and a second protrusion, the first protrusion and the second protrusion are protruded from the surface of the partition plate and are arranged at intervals, the first protrusion, the second protrusion and the partition plate form a containing groove for containing the charging head, a first magnetic part is arranged on the partition plate, a second magnetic part is arranged in the charging head, when the charging head is installed in the containing groove, the charging head can be fixed on the card seat through the adsorption of the first magnetic part and the second magnetic part, when the charging head is fixed on the card seat, the charging line is bent to form a ring-shaped portable structure.

[0006] Compared to existing technologies, the portable power bank of this invention uses a first and second protrusion to form a receiving groove, and magnetically attaches the charging head to the receiving groove. This allows the charging cable to bend into a loop-shaped carrying structure, enabling users to hook their fingers onto the loop-shaped carrying structure for easy carrying. Furthermore, it eliminates the need to occupy space within the charging unit to house the charging cable and charging head, thus reducing the overall size of the charging unit. Additionally, the charging head can only be assembled or detached from the receiving groove through openings on the top or sides, resulting in a better user experience when assembling the charging head.

[0007] Furthermore, the charging cable is connected to the rear end of the charging head in the insertion direction. When the charging head is placed in the receiving slot, the first protrusion is located on the side where the charging head connects to the charging cable, and the second protrusion is located on the front end side in the insertion direction of the charging head. When the ring-shaped carrying handle is lifted by hand, the charging head abuts against the first protrusion, which can assist in positioning the charging head.

[0008] Furthermore, the surface of the first protrusion facing the receiving groove forms a first angle with the partition plate, the first angle being greater than 0° and less than 90°, and the surface of the charging head facing the first protrusion is parallel to the surface of the first protrusion facing the receiving groove. The angle formed between the first protrusion and the partition plate better confines the charging head within the receiving groove, preventing it from detaching from the opening above the receiving groove.

[0009] Furthermore, the surface of the second protrusion facing the receiving groove is parallel to the surface of the first protrusion facing the receiving groove, and the surface of the charging head facing the second protrusion is parallel to the surface of the second protrusion facing the receiving groove. The surface of the second protrusion facing the receiving groove forms an obtuse angle with the partition plate, which facilitates the charging head to be pried upward from the front end of the receiving groove in the insertion direction.

[0010] Furthermore, the charging head includes a body and a plug-in end located at the front end of the body. When the charging head is placed in the receiving slot, the upper surface of the second protrusion is located below the plug-in end. Because the connection position between the plug-in end of the charging head and the body of the charging head is stepped, when the charging head is inserted into the receiving slot, the second protrusion extends into the stepped position, preventing the receiving slot from being too long and causing the card holder to be too large.

[0011] Furthermore, when the charging head is placed in the receiving groove, the upper surface of the first protrusion abuts against the charging cable, and / or the upper surface of the second protrusion abuts against the plug-in end. This ensures that there is no gap between the end of the charging head connected to the charging cable and the first protrusion, preventing the charging head from tilting out of the receiving groove under force.

[0012] Furthermore, there are two charging heads and two charging cables, which can be housed side by side in the receiving slot. When one charging head is charging, the other charging head can be embedded in the slot to form a handle, making it convenient for the user to carry the power bank while charging.

[0013] Preferably, there are two of the first and second protrusions, and each of the two first and two second protrusions forms a receiving groove on opposite surfaces of the partition plate. There are also two charging heads and two charging cables, each of which can be accommodated in one of the receiving grooves. When one charging head is charging, the other charging head can be embedded in the slot to form a handle, making it convenient for the user to carry the power bank while charging.

[0014] Furthermore, the card holder is connected to the charging unit via a connecting cable, with one end of the cable connected to the card holder and the other end connected to the charging unit. This ensures that the card holder does not occupy space within the charging unit.

[0015] Furthermore, the connection portions of the two charging cables and the charging unit are located on the same side of the connecting line, wherein one charging cable is positioned adjacent to the connecting line relative to the other charging cable, and the length of the charging cable adjacent to the connecting line is shorter than the length of the other charging cable. When the charging cable adjacent to the connecting line is bent to form a loop handle structure, it is wrapped inside the handle structure formed by the other charging cable. This allows the handle formed by one charging cable to be wrapped inside the handle formed by the other charging cable, forming a single handle.

[0016] Preferably, the card holder can also be disposed on the charging cable or on the housing of the charging unit. This eliminates the need for an additional connecting cable to connect the card holder to the charging unit.

[0017] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0023] This invention redesigns the structure of a portable power bank by incorporating a locking mechanism between the charging head and the card slot, allowing the charging cable to be bent into a loop-shaped handle for easy carrying.

[0024] The following is a detailed description of the charging stand designed according to the present invention, with reference to the accompanying drawings.

[0025] Please see Figure 2 and Figure 3 This embodiment of the portable power bank includes a charging unit 10, a card holder 20, a first charging head 30, a first charging cable 40, a second charging head 50, and a second charging cable 60. The card holder is connected to the outer shell of the charging unit 10 via a connecting cable 50. One end of the connecting cable 50 is connected to the card holder 20, and the other end is connected to the outer shell of the charging unit 10. One end of the first charging cable 40 and the second charging cable 60 are connected to the outer shell of the charging unit 10, and the other end is respectively connected to the first charging head 30 and the second charging head 50. The first charging head 30 and the second charging head 50 can be fixedly connected to the card holder 20, thereby bending the first charging cable 40 and the second charging cable 60 to form a ring-shaped carrying structure. At the same time, when one charging head is charging, the other charging head can also be embedded in the card holder to form a handle, making it convenient for the user to carry the power bank.

[0026] Specifically, in this embodiment, please refer to Figure 4 The card holder 20 includes a partition plate 21, a first protrusion 22, and a second protrusion 23. The first protrusion 22 and the second protrusion 23 protrude from the surface of the partition plate 21 and are spaced apart. There are two of the first protrusion 22 and the second protrusion 23. The two first protrusions 22 and the two second protrusions 23 respectively form a first receiving groove 24 and a second receiving groove 25 with the opposite two surfaces of the partition plate 21. The first receiving groove 24 is located on the partition plate near the connection portion of the first charging cable 40 and the second charging cable 60 connected to the charging unit 10. The first charging head 30 and the second charging head 50 can be placed in the first receiving groove 24 and the second receiving groove 25, respectively.

[0027] The first charging head 30 includes a first charging head body 31 and a first charging head connector 32 located at the front end of the first charging head body 31, and the rear end of the first charging head body 31 is connected to the first charging cable 40. The second charging head 50 includes a second charging head body 51 and a second charging head connector 52 located at the front end of the second charging head body 51, and the rear end of the second charging head body 51 is connected to the second charging cable 60.

[0028] The first protrusion 22 is disposed on the partition plate 21 and located at the end where the first charging head 30 and the second charging head 50 are connected to their charging cables; the second protrusion 23 is disposed on the partition plate 21 and located at the end where the first charging head 30 and the second charging head 50 are connected to their plug-in ends. The upper surfaces of the two second protrusions 23 are respectively located below the plug-in ends 32 and 52 of the first charging head and the second charging head. Since the connection position between the plug-in ends of the first charging head 30 and the second charging head 50 and the charging head body is stepped, when the first charging head 30 and the second charging head 50 are inserted into the first receiving slot 24 and the second receiving slot 25, the two second protrusions 23 extend into the stepped position, avoiding excessive length of the first receiving slot 24 and the second receiving slot 25, which would result in an excessively large volume of the card holder 20. The upper surfaces of the two first protrusions 22 abut against the first charging cable 40 and the second charging cable 60, respectively, while the upper surfaces of the two second protrusions 23 abut against the insertion ends of the first charging head 30 and the second charging head 50. This ensures that there is no gap between the end of the charging head connected to the charging cable and the first protrusion 22, preventing the charging head from tilting out of the receiving groove under force.

[0029] The partition plate 21 is also embedded with a first magnetic element 26; the first charging head 30 and the second charging head 50 are respectively provided with a second magnetic element 34 and a third magnetic element 54 near their contact with the partition plate 21. When the first charging head 30 and the second charging head 50 are placed in the first receiving groove 24 and the second receiving groove 25 respectively, the first magnetic element 26 can attract the second magnetic element 34 and the third magnetic element 54, thereby fixing the first charging head 30 and the second charging head 50 in the first receiving groove 24 and the second receiving groove 25 of the card holder 20. At this time, the first charging head 30 and the second charging head 50 respectively abut against the two first protrusions 22 to provide auxiliary positioning for the charging head and prevent the charging head from falling out. Thus, the first charging cable 40 and the second charging cable 60 form a ring-shaped handle structure, which allows consumers to hook their fingers on the ring-shaped handle structure when carrying the power bank, making it easy to carry. At the same time, it does not require occupying the volume of the charging unit 10 to store the charging cable and charging head, thus reducing the volume of the charging unit 10. Meanwhile, the charging head can only be assembled or detached from the openings on the top or sides of the receiving slot, thus providing a better user experience when assembling the charging head.

[0030] Furthermore, the surfaces of the two first protrusions 22 facing the receiving groove form a first angle 221 with the partition plate 21. The first angle 221 is greater than 0° and less than 90°. The surfaces of the first charging head 30 and the second charging head 50 facing the first protrusion 22 are parallel to the surfaces of the first protrusion 22 facing the receiving groove. The first angle 221 formed by the first protrusion 22 and the partition plate 21 better confines the charging head within the receiving groove, preventing it from detaching from the opening direction above the receiving groove. The surface of the second protrusion 23 facing the receiving groove is parallel to the surface of the first protrusion 22 facing the receiving groove. The surfaces of the first charging head 30 and the second charging head 50 facing the second protrusion 23 are respectively parallel to the surfaces of the two second protrusions 23 facing the receiving groove. The surface of the second protrusion 23 facing the receiving groove forms an obtuse angle with the partition plate 21, facilitating the charging head to be pried upwards from the front end in the insertion direction from the receiving groove.

[0031] Preferably, the connection portions of the first charging cable 40 and the second charging cable 60 with the charging unit 10 are located on the same side of the connecting line 70, wherein the first charging cable 40 is disposed adjacent to the connecting line 70 relative to the second charging cable 60, wherein the length of the first charging cable 40 is shorter than the length of the second charging cable 60, and when the first charging cable 40 is bent to form a loop handle structure, it is wrapped inside the handle structure formed by the second charging cable 60. When the first charging head 30 and the second charging head 50 are both placed in the receiving groove, the first charging cable 40 and the second charging cable 60 together form a handle.

[0032] In another embodiment, the number of the first protrusion 22 and the second protrusion 23 is one, and the first protrusion 22 and the second protrusion 23 form a receiving groove with one of the surfaces of the partition plate 21, and the first charging head 30 and the second charging head 50 can be placed side by side in the receiving groove.

[0033] In another embodiment, the card holder 20 is disposed on the first charging cable 40 and the second charging cable 60. One end of the first charging cable 40 and the second charging cable 60 are connected to the charging unit 10, and the other end passes through the interior of the card holder 20 and is respectively connected to the first charging head 30 and the second charging head 50. Compared with this embodiment, the connecting line 70 is eliminated, and a part of the charging cable 40 (60) replaces the function of the connecting line 70 in this embodiment, reducing the structural complexity.

[0034] Alternatively, in another embodiment, the card holder 20 is directly mounted on the outer shell of the charging unit 10, eliminating the connecting wire 70 compared to this embodiment and reducing the structural complexity of the entire portable power bank.

[0035] Compared to existing technologies, this portable power bank fixes the charging head to the socket connected to the charging unit and bends the charging cable to form a loop-shaped handle structure, allowing users to hold the power bank through this loop-shaped handle structure, improving the user's grip experience. At the same time, when using one of the charging heads of the power bank for charging, the other charging cable can also form a loop-shaped handle structure, making it easy for users to hold the power bank while charging and reducing the difficulty of holding it.
