[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] The buzzer 12 used in this application is a product that can be directly purchased on the market. Its principle and connection method are both well-known prior arts to those skilled in the art, so it will not be elaborated here.

[0024] A multifunctional combined power bank includes a housing, the housing includes a power bank body 1, a socket 11 is provided on the surface of the power bank body 1, a buzzer 12 is fixedly installed on the surface of the power bank body 1, a control circuit is provided inside the power bank body 1, and the buzzer 12 is electrically connected to the control circuit. When the control circuit detects a change in current, it can identify whether the power bank is in a charging or discharging state, and then trigger the buzzer 12 to emit a corresponding prompt sound, so as to remind the user of the current state of the power bank, increasing the functionality of the power bank, making the use of the power bank more convenient, and also facilitating the use of the blind;

[0025] A carrying mechanism is provided on the surface of the power bank body 1. The carrying mechanism includes a fixed block 2, which is fixedly connected to the surface of the power bank body 1. A rotating rod 21 is movably connected to the inner side of the fixed block 2. A turntable 22 is fixedly connected to the surface of the rotating rod 21. A connecting rope 23 is fixedly connected to the surface of the rotating rod 21. A gear 24 is fixedly connected to the surface of the rotating rod 21. A limiting rod 25 is movably connected to the inner side of the fixed block 2. A pulling block 26 is fixedly connected to the surface of the limiting rod 25. A first spring 27 is fixedly connected to the surface of the pulling block 26. By rotating the turntable 22, the turntable 22 can drive the rotating rod 21 to rotate. Furthermore, the rotation of the rotating rod 21 can wind and unwind the connecting rope 23, facilitating the storage of the connecting rope 23. At the same time, the connecting rope 23 can also be unwound to the required length to realize the wearing of the connecting rope 23, thus making the use of the power bank body 1 more convenient.

[0026] Furthermore, one end of the connecting rope 23 is fixedly connected to the rotating rod 21, and the other end of the connecting rope 23 is fixedly connected to the power bank body 1. The connecting rope 23 is wound around the surface of the rotating rod 21. Through the setting of the connecting rope 23, the connecting rope 23 can be hung on the wrist or around the neck. Furthermore, when using the power bank body 1, it is more convenient to carry the power bank body 1 without having to hold the power bank body 1 by hand.

[0027] Furthermore, the connecting rope 23 is movably connected to the inner side of the fixed block 2, and the gear 24 is movably connected to the inner side of the fixed block 2. Through the setting of the gear 24, when the limiting rod 25 limits and cancels the limit of the gear 24, the rotating rod 21 can be rotated, and thus the connecting rope 23 can be wound and unwound through the rotating rod 21.

[0028] Furthermore, one end of the first spring 27 is fixedly connected to the fixed block 2, and the other end of the first spring 27 is fixedly connected to the pulling block 26. Through the setting of the first spring 27, the pulling block 26 can be reset. Furthermore, the pulling block 26 can drive the limiting rod 25 to reset accordingly, and the limiting of the gear 24 by the limiting rod 25 can be realized.

[0029] Furthermore, an anti - detachment mechanism is provided on the surface of the power bank body 1. The anti - detachment mechanism includes a connecting block 3, which is fixedly connected to the surface of the power bank body 1. An activity groove 31 is opened in the inner side of the connecting block 3. A second spring 32 is fixedly connected to the inner wall of the activity groove 31. A rubber block 33 is fixedly connected to the surface of the second spring 32. When the plug of the data cable is inserted into the socket 11, through the setting of the second spring 32, a certain force can be applied to the rubber block 33. Furthermore, the rubber block 33 can be made to fit against the surface of the plug, making it difficult for the plug to fall out of the socket 11, and thus the charging process is more stable.

[0030] Further, one end of the second spring 32 is fixedly connected to the movable groove 31, and the other end of the second spring 32 is fixedly connected to the rubber block 33. The rubber block 33 is movable inside the movable groove 31. Through the arrangement of the rubber block 33, the surface of the plug of the data cable inserted into the socket 11 can be abutted, so that the insertion of the plug and the socket 11 can be more stable.

[0031] Working principle: During use, by pulling the pull block 26, the limiting rod 25 will move inside the fixed block 2 under the action of the pull block 26, and the limiting of the gear 24 by the limiting rod 25 can be cancelled. At this time, the first spring 27 is in a stretched state. Then, rotate the turntable 22, and the rotating rod 21 and the gear 24 will rotate accordingly under the action of the turntable 22, so that the winding and unwinding of the connecting rope 23 can be realized. Then, by releasing the pull block 26, the pull block 26 will drive the limiting rod 25 to reset under the rebounding action of the first spring 27, so that the limiting rod 25 is inserted into the tooth groove of the gear 24 to realize the limiting of the gear 24, and the connecting rope 23 can be adjusted to the required length. Then, put the connecting rope 23 on the wrist or neck to realize the carrying of the power bank body 1.

[0032] During the process of inserting the plug of the data cable into the socket 11, when the plug contacts the rubber block 33, the rubber block 33 will be squeezed, and then the rubber block 33 will move towards the inside of the movable groove 31. At this time, the second spring 32 is in a contracted state, and at the same time, the second spring 32 will exert a certain force on the rubber block 33, so that the rubber block 33 can abut against the surface of the plug. After the plug and the socket 11 are inserted, the rubber block 33 can strengthen the connection between the plug and the socket 11, making the plug not easy to fall off.

[0033] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention; any ordinary technical personnel in the industry can smoothly implement the present invention according to the instructions in the drawings and the above; however, any minor changes, modifications and evolutions made by those skilled in the art within the scope of the technical solution of the present invention using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
