[0032] The utility model provides a mobile power source.

[0033] See also Figure 1 , 35. In one embodiment of the utility model, the mobile power supply includes a housing 100, a battery 200, a charging base 300, a charging head 400 and a lanyard mounting structure 500. The housing 100 is provided with a housing cavity 110; the battery 200 is located in the housing cavity 110, and the battery 200 is used to store and output electrical energy. It can be understood that the charging base 300 can be an independent structure and is connected to the housing 100; the charging base 300 can also be integrated with the housing 100, and is formed by the housing 100 being recessed inward. Preferably, the charging base 300 is an independent structure for easy processing and manufacturing. The charging base 300 is provided with at least one storage slot 310, and the number of storage slots 310 can be designed according to the number of charging heads 400 required. Preferably, there can be two storage slots 310 to accommodate two different charging heads 400 (the charging interface of most electronic devices at present is a Type-c interface or a Lightning interface, so that the charging needs of most electronic devices can be met). The side wall of the storage slot 310 is provided with a rotation slot 311, and the side wall of the charging head 400 is provided with a rotation protrusion 410, and the rotation protrusion 410 is taken into the rotation slot 311, so that the charging head 400 can rotate around the rotation slot 311. As a preference, the rotation protrusion 410 can be set to a columnar shape. The charging head 400 is arranged in the storage slot 310, and the charging head 400 is rotatably connected with the rotation slot 311. The first end of the charging head 400 is electrically connected to the battery 200, and the second end of the charging head 400 is used to connect the electronic device; the charging head 400 rotates around the rotation slot 311 so that the charging head 400 is in a charging state or a storage state. That is, the charging head 400 can be rotated into or out of the storage slot 310 by rotating around the rotation slot 311. When the charging head 400 is rotated into the storage slot 310, the charging head 400 is in a storage state; when the charging head 400 is rotated out of the storage slot 310, the charging head 400 is in a charging state. It can be understood that the charging state includes the charging state in which the charging head 400 is connected to the electronic device and the ready-to-charge state in which the electronic device is not yet connected. The setting of the storage slot 310 and the rotation setting of the charging head 400 can realize the storage of the charging head 400 to reduce the risk of damage to the charging head 400 and improve the portability of the mobile power supply. At the same time, considering that the first end of the charging head 400 needs to be connected to the battery 200 located in the accommodating cavity 110, and when the charging head 400 rotates around the axis in the storage slot 310, the first end of the charging head 400 will be hindered by the inner wall of the storage slot 310; based on this, an avoidance channel 312 is set in the storage slot 310, and when the charging head 400 rotates around the rotation slot 311, the first end of the charging head 400 passes through the avoidance channel 312, so that the first end of the charging head 400 can be smoothly connected to the battery 200, and the first end of the charging head 400 can be smoothly rotated.Through the above arrangement, the mobile power supply can directly charge the electronic device through the charging head 400, reducing the need for data cables and improving the convenience of charging; and because the length of the charging head 400 is greatly shortened compared to the data, it is easier to splice with the electronic device to form a whole when charging the electronic device, so that it is more convenient to move with the electronic device. In addition, the lanyard mounting structure 500 of the mobile power supply can be used to install a lanyard to further improve the portability of the mobile power supply when moving. The lanyard mounting structure 500 includes a first penetration hole 510, a second penetration hole 520 and a guide 530, the first penetration hole 510 and the second penetration hole 520 are arranged at intervals in the housing 100, and the first penetration hole 510 and the second penetration hole 520 are connected to the accommodating chamber 110; the guide 530 is located in the accommodating chamber 110, and is used to guide one end of the lanyard to pass through the first penetration hole 510 and pass through the second penetration hole 520. The portion of the housing 100 between the first penetration hole 510 and the second penetration hole 520 can be used to abut against the portion of the hanging rope inserted into the accommodating cavity 110, so as to serve as a fulcrum for the hanging rope when in use.

[0034] In some embodiments, see Figure 4 , 5 When the charging head 400 is in the storage state, the side wall of the charging head 400 abuts against the bottom wall of the storage groove 310; when the charging head 400 is in the charging state, the side wall of the charging head 400 abuts against the side wall of the storage groove 310 near the first end of the charging head 400; the rotation angle of the charging head 400 around the rotation groove 311 is between 0 and 90 degrees. It can be understood that when the charging head 400 is in the storage state, the highest point of the peripheral side wall of the charging head 400 can be less than or equal to the depth of the storage groove 310, so as to facilitate storage and carrying and prevent the charging head 400 from being damaged. When the charging head 400 is in the charging state, the distance between the second end of the charging head 400 and the bottom wall of the storage groove 310 should be greater than the depth of the storage groove 310, so that the second end of the charging head 400 can be better connected to the electronic device. Preferably, the storage slot 310 may be arranged in a square or rectangular shape so that the bottom wall of the storage slot 310 is perpendicular to the side wall of the storage slot 310. At this time, when the rotation angle of the charging head 400 is 0°, the charging head 400 is in a storage state; when the rotation angle of the charging head 400 is 90°, the charging head 400 is in a charging state.

[0035] Further, in some embodiments, see Figure 5 , 6, a first notch 3121 is provided on the side wall of the storage groove 310 near the first end, a second notch 3122 is provided on the bottom wall of the storage groove 310, and the first notch 3121 and the second notch 3122 are connected to form an avoidance channel 312. It can be understood that in order to make the matching arrangement of the charging head 400 and the storage groove 310 more compact, the side wall of the charging head 400 abuts against the bottom wall of the storage groove 310, and the depth of the storage groove 310 is slightly greater than the highest point of the peripheral side wall of the charging head 400. Therefore, when the charging head 400 rotates around the axis in the storage slot 310, the first end of the charging head 400 will be hindered by the inner wall of the storage slot 310 (the side wall and bottom wall of the storage slot 310 close to the first end); in addition, considering that the first end of the charging head 400 needs to be connected to the battery 200 located in the accommodating cavity 110; therefore, the first notch 3121 and the second notch 3122 are set at the corresponding positions of the storage slot 310 to form an avoidance channel 312. Such a setting is conducive to improving the smoothness of the charging head 400 when rotating; and provides a channel for the first end of the charging head 400 to connect with the battery 200.

[0036] Further, in some embodiments, the side wall of the second notch 3122 is provided with a first limiting protrusion 313, and the first limiting protrusion 313 is arranged in a first arc shape; the first end of the charging head 400 is provided with a limiting groove 420, and the limiting groove 420 is arranged in a second arc shape, and the first arc shape and the second arc shape can be slidably matched. It can be understood that when the charging head 400 is in the charging state, the first limiting protrusion 313 is clamped in the limiting groove 420 to reduce the shaking of the charging head 400 during charging. The first arc shape and the second arc shape can be slidably matched, and when it is necessary to switch to the storage state, a little force can be applied to slide the first limiting protrusion 313 out of the limiting groove 420, so that the charging head 400 can be rotated to recover the storage groove 310.

[0037] Accordingly, in some embodiments, the side wall of the first notch 3121 is provided with a second limiting protrusion 314, the second limiting protrusion 314 is arranged in a third arc shape, the first end of the charging head 400 is provided with a limiting groove 420, the limiting groove 420 is arranged in a second arc shape, and the third arc shape and the second arc shape can be slidably matched. It can be understood that when the charging head 400 is in the storage state, the second limiting protrusion 314 is clamped in the limiting groove 420 to reduce the possibility of the charging head 400 sliding out of the storage groove 310 during the movement or flipping of the mobile power supply. The third arc shape and the second arc shape can be slidably matched, so that when it is necessary to switch to the charging state, a little force can be applied to slide the second limiting protrusion 314 out of the limiting groove 420 so that the charging head 400 can be rotated.

[0038] Further, in some embodiments, see Figure 4When the charging head 400 is in the storage state, a rotating driving member 430 is provided on the side in contact with the outside world, and the rotating driving member 430 is used to drive the charging head 400 to rotate around the rotating groove 311. The rotating driving member 430 can be a protrusion or a pull ring to facilitate the charging head 400 to be rotated out of the storage groove 310.

[0039] In some embodiments, see Figure 1 , 3 The guide member 530 is located at the corresponding position of the first through hole 510 and the second through hole 520; the guide member 530 is connected to the inner wall of the housing 100; the guide member 530 is concavely arranged on one side close to the first through hole 510 and the second through hole 520. It can be understood that the concave arrangement of the guide member 530 is conducive to expanding the space for the hanging rope to pass through and guiding the direction of one end of the hanging rope.

[0040] In some embodiments, see Figure 2 , 7 The mobile power supply also includes a bracket 600; the bracket 600 is rotatably connected to the housing 100 and is spaced apart from the charging stand 300. The bracket 600 can be adjusted to a suitable placement angle so that the mobile power supply can be tilted accordingly, so as to achieve the effect of charging and using electronic devices while being placed on a desktop or other placement surface. Specifically, the housing 100 is provided with a receiving groove 120 and a rotating shaft 130, and one end of the bracket 600 is rotatably connected to the rotating shaft 130; the bracket 600 leaves or enters the receiving groove 120 around the rotating shaft 130. With such a configuration, the receiving groove 120 can accommodate the bracket 600 to reduce the interference of the bracket 600 with the normal use of the mobile power supply.

[0041] In some embodiments, see Figure 1 , 3 The mobile power supply further includes a circuit board 700, which is electrically connected to the battery 200; a clamping member 140 is provided on the inner side wall of the housing 100; the circuit board 700 is clamped to the clamping member 140 to be connected to the housing 100; and the charging stand 300 is connected to the housing 100 by being mounted on the circuit board 700. It can be understood that the general function of the circuit board 700 is to manage the charging of the mobile power supply, including the switching of charging and discharging of the battery 200, the status monitoring of the battery 200, etc. Since the circuit board 700 adopts the relevant technology in the prior art and has the beneficial effects brought by the relevant technology, it will not be described one by one here.

[0042] In some embodiments, see Figure 1 , 3, the mobile power supply also includes a wireless charging device 710, which is located on the surface of the housing 100; and / or, the mobile power supply also includes a display screen 720, which is located on the surface of the housing 100 and is used to display the power; and / or, the mobile power supply also includes a switch key 730, which is located on the surface of the housing 100 and is used to turn on or off charging; and / or, the mobile power supply also includes an input interface 740, which passes through the opening of the housing 100 and is connected to the circuit board 700, and the circuit board 700 is used to connect the input power supply. It can be understood that the mobile power supply also integrates related functions such as wireless charging and screen display, which is conducive to enriching the use scenarios of the mobile power supply.
