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. SUMMARY

[0004] Therefore, the utility model discloses the purpose of providing a portable power bank, which can make the charging line of the power bank bend 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 shell of the charging unit, a first magnetic member is arranged in the card seat, a second magnetic member is arranged in the charging head, the second magnetic member is adsorbed with the first magnetic member, so that the charging head is fixed on the card seat, and the charging line bends to form a ring-shaped portable structure when the charging head is fixed on the card seat.

[0006] Compared with the prior art, the portable power bank disclosed by the utility model fixes the charging head on the card seat through magnetic adsorption, so that the charging line bends to form a ring-shaped portable structure, so that the consumer user can hook the ring-shaped portable structure with fingers when carrying the power bank, which is convenient for carrying, and at the same time, the charging line and the charging head do not need to occupy the volume of the charging unit, so that the volume of the charging unit is reduced.

[0007] Further, the surface of the card seat is concave and has a receiving groove for accommodating the charging head. The charging head is further clamped on the card seat through the receiving groove to prevent the charging head from sliding out.

[0008] Further, the side wall of the receiving groove is provided with a clamping block, and the charging head is provided with a clamping groove corresponding to the position of the clamping block. When the charging head moves in the receiving groove in a first direction, the clamping groove is clamped to the clamping block to limit the movement of the charging head away from the bottom wall of the receiving groove. When the charging head moves in the receiving groove in a second direction, the clamping groove is disengaged from the clamping block. The first direction and the second direction are opposite. Through the clamping structure of the clamping groove on the charging head and the clamping block on the side wall of the receiving groove, the charging head on the card seat is further clamped to prevent the charging head from sliding out.

The charging line can be clamped into the clamping groove, so that the charging head can be more deeply embedded in the receiving groove. At the same time, it can also increase the contact area between the charging head and the side wall of the receiving groove, improve the stability of the power bank when it is held by hand, and avoid the charging head from easily coming off the receiving groove.

[0012] Further, the second magnetic member is arranged on one side of the charging head center deviated from the first magnetic member to reduce the distance between the first magnetic member and the second magnetic member, thereby improving the magnetic attraction force and making the charging head more firmly fixed to the card seat.

[0013] Further, the number of receiving grooves is two, and the charging line and the charging head are correspondingly provided with two. Two charging heads are respectively fixed in two receiving grooves to form a ring-shaped hand-held structure. When the user uses one of the charging heads for charging, the other charging head can also be fixed in the card seat to form a ring-shaped hand-held structure, which is convenient for the user to hold the power bank by hand during charging.

[0014] Preferably, the side walls of the two accommodating grooves are respectively provided with clamping blocks, each of the charging heads is provided with a clamping groove corresponding to the position of the clamping block, when the charging head moves in the accommodating groove along a first direction, the clamping groove is clamped to the clamping block to limit the movement of the charging head away from the bottom wall of the accommodating groove, when the charging head moves in the accommodating groove along a second direction, the clamping groove is separated from the clamping block, the first direction and the second direction are opposite, and the first direction and the second direction of the two charging heads are respectively the same. It is convenient for users to remember the taking-out direction of the two charging heads, avoids the different taking-out directions from being confused by users, and improves the use experience of users.

[0015] Further, the card seat is connected to the shell of the charging unit through a connecting line, one end of the connecting line is connected to the card seat, and the other end is connected to the shell of the charging unit. The card seat is designed outside the charging unit, thereby reducing the volume of the charging unit.

[0016] Further, the connecting parts of the two charging lines and the charging unit are located on the same side of the connecting line, one of the charging lines is arranged adjacent to the connecting line relative to the other charging line, the length of the charging line adjacent to the connecting line is shorter than the length of the other charging line away from the connecting line, and the charging line adjacent to the connecting line is wrapped in the hand-held structure formed by the other charging line away from the connecting line. One of the charging lines forms a handle which can be wrapped in the hand-held structure formed by the other charging line, and the whole forms a handle.

[0017] Preferably, the card seat can also be arranged on the charging line or the shell of the charging unit. The card seat no longer needs to be connected to the charging unit through an additional connecting line.
