Description

Technical Field

[0002] A mobile power source is a portable power device that is mainly used to provide power to various electronic devices. In particular, it can charge mobile phones, tablets and other devices when there is no external power supply. Mobile power sources are usually called mobile power sources, mobile chargers, power banks, etc.

[0003] The mobile power banks currently in use still have the following problems: 1. They generally do not have an automatic reeling function, which makes it difficult to store long data cables, affecting the carrying effect; 2. Although some mobile power banks have multi-port charging functions, multi-port charging cables are not conducive to subsequent sorting and will also affect the carrying effect; 3. The heat dissipation state cannot be automatically adjusted according to the charging situation. When multi-port charging is performed, the mobile power bank itself will dissipate heat, which is not conducive to heat dissipation. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the user presses the control switch on the left side through the plastic control frame, the drive motor is driven forward to realize the automatic extension of the data line. When the user presses the control switch on the left side again, the drive motor stops working.

When the user presses the control switch on the right side again, the drive motor stops working.

[0019] In addition, when the drive motor drives the winding disc to rotate, the extrusion drive block can automatically drive the data cable to move accurately, ensuring that the data cable can be extended and stored normally;

[0020] In addition, when the drive motor is working, the winding disc can rotate along with the output shaft of the drive motor under the action of two arc-shaped limit grooves and two circular limit rods; when the data cable is in a fully extended or fully retracted state and the drive motor continues to work, the output shaft of the drive motor pushes the two circular limit rods to move outward automatically, so that the two circular limit rods are automatically separated from the two arc-shaped limit grooves. At this time, the winding disc does not rotate along with the output shaft of the drive motor, thereby avoiding damage to the data cable and loosening of the connection between the data cable and the lithium battery.

[0021] 2. When the multi-way connector needs to be taken out, the user pulls the movable sealing cover downward, and the movable sealing cover can be separated from the two arc-shaped openings after moving downward, so that the multi-way connector can fall through one of the arc-shaped openings. The setting of the multi-way connector increases the number of charging interfaces; when the multi-way connector is taken out, the movable sealing cover can automatically move under the action of two reset springs B;

[0022] In addition, when the multi-way connector is in the removed state, there is a certain gap between the two conical sealing blocks and the two heat dissipation circular hole brackets, which is conducive to the dissipation of heat from the lithium battery, and has a better heat dissipation effect when charging multiple interfaces; when the multi-way connector is in the stored state, the two conical sealing blocks automatically seal the two heat dissipation circular holes to prevent impurities from entering the storage ring when carrying; when charging with one interface, the lithium battery basically does not generate heat, and at this time, there is no need to improve the heat dissipation effect.

[0051] The winding unit 400 includes: a winding disc 401, a V-shaped mounting frame 402 and a circular limiting rod 403; the winding disc 401 is rotatably mounted on the output shaft of the driving motor 304, and the winding disc 401 is located between the two limiting rings 305, and the winding disc 401 is also meshed and connected with the connecting gear 308; there are two V-shaped mounting frames 402, and the two V-shaped mounting frames 402 are fixedly mounted on the winding disc 401; there are two circular limiting rods 403, and the two circular limiting rods 403 are slidably mounted on the winding disc 401 and the two V-shaped mounting frames 402; the inner ends of the two circular limiting rods 403 are provided with The inner ends of the two circular limiting rods 403 are inserted into the two arc-shaped limiting grooves 3041; the winding unit 400 also includes: a reset collar 404 and a reset spring A405; there are two reset collars 404, which are fixedly mounted on the outside of the two circular limiting rods 403, and the inner sides of the two reset collars 404 are in contact with the winding disc 401; there are two reset springs A405, which are sleeved on the outside of the two circular limiting rods 403, and the two reset springs A405 are located between the two V-shaped mounting frames 402 and the two reset collars 404;

[0052] The specific function is as follows: since the drive motor 304 is fixedly mounted on the mounting base 301, and the drive motor 304 is also electrically connected to the lithium battery 200 and the two control switches 303, when the user presses the control switch 303 on the left side through the plastic control frame 103, the drive motor 304 is in forward rotation, realizing the automatic extension of the data line 500; when the user presses the control switch 303 on the left side again, the drive motor 304 stops working; when the user presses the control switch 303 on the right side through the plastic control frame 103, the drive motor 304 is in reverse rotation, realizing the automatic extension of the data line 500.

The setting of the multi-way connector 600 increases the number of charging interfaces; when the multi-way connector 600 is taken out, the movable sealing cover 703 can automatically move under the action of the two reset springs B704; when the multi-way connector 600 is in the taken-out state, the two conical sealing blocks 705 and the two heat dissipation There is a certain gap in the bracket of the circular hole 7031, which is conducive to the heat dissipation of the lithium battery 200, and has a better heat dissipation effect when multiple interfaces are charged; when the multi-way connector 600 is in the storage state, the two conical sealing blocks 705 automatically seal the two heat dissipation circular holes 7031 to prevent impurities from entering the storage ring 701 when carrying; when charging with one interface, the lithium battery 200 basically does not generate heat, and at this time, there is no need to improve the heat dissipation effect; then the user presses the control switch 303 on the left side through the plastic control frame 103, at this time, the driving motor 304 is in the forward direction, and the data line 500 is realized.
