[0015] The following is a detailed description of the embodiments of the present invention. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0016] As one aspect of the present invention, a portable mobile power supply for wearable products is provided, including: a TYPE-C interface P2 used as a charging input and output port, a controller U2 (for example, XL9989), a DC / DC module U1 (for example, ETA9742), a wearable product power supply interface DC1, a first switching element Q2 and a battery (not shown), the 14th and 15th pins of the controller U2 are electrically connected to the DC / DC module U1, the positive pole of the TYPE-C interface P2 and the positive pole of the wearable product power supply interface DC1 are both connected to the output pin OUT of the DC / DC module U1, the battery pin BAT of the DC / DC module U1 is connected to the positive pole of the battery, the negative pole of the wearable product power supply interface DC1 is grounded through the first switching element Q2, the first pin of the controller U2 is connected to the control end HEAT of the first switching element Q2, and the battery is connected to the interface P1.

[0017] Preferably, the cathode of the TYPE-C interface P2 is grounded via a second switch element Q1, and the second pin of the controller U2 is connected to the control terminal TC-ON of the second switch element Q1. Thus, when power is supplied to a wearable product via the wearable product power supply interface DC1, the cathode of the TYPE-C interface P2 can be disconnected via the second switch element Q1, powering only the wearable product.

[0018] Preferably, the negative electrode of the battery is electrically connected to a lithium battery protection chip U3. For example, the model of the lithium battery protection chip U3 may be XB5632. If overcharge or over-discharge is detected, the negative electrode of the battery is disconnected to protect the battery.

[0019] Preferably, the portable power bank for wearable products further includes an LED indicator circuit for indicating the power level and output gear, and the LED indicator circuit is electrically connected to the controller U2. The LED indicator circuit includes LEDs D1-D4, which can be used to indicate the power level and output gear of the external power, thereby controlling the heating power of the wearable product.

[0020] Refer to Figures 1 through 5. To charge, plug the external charging cable into Type-C port P2. Power from Type-C port P2 flows into pin 7 of the DC / DC module U1, then out through pin 6 to port P2, charging the battery. When discharging, power from the battery flows into pin 6 of the DC / DC module U1, then through pin 7 to the Type-C port P2 or the wearable device power port DC1. Controller U2 is connected to pins 3 and 4 of the DC / DC module U1 to monitor and control the charging and discharging process.

[0021] When in use, the wearable product power supply interface DC1 is connected to the power input interface of the wearable product, which can be heating gloves, heating socks, heating clothing (heating vests, etc.). The controller U2 can control the heating power by controlling the on and off of the first switching element Q2.

[0022] Due to the adoption of the above technical solution, the utility model can be used to supply power to wearable products and adjust the heating power of wearable products. Its TPYE-C interface can be used for charging and supplying power to other devices. It has the characteristics of small size, easy to carry and long battery life.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
