Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, and particularly relates to a mobile power supply with a rotating interface. Background Art

[0002] A mobile power supply is a portable charger that integrates power supply and charging functions. Since a mobile power supply can charge mobile phones, tablet computers and other terminals anytime and anywhere, the use of mobile power supplies is becoming more and more widespread.

[0003] At present, most of the mobile power supplies sold on the market are wired charging type mobile power supplies. During the charging process of the mobile power supply to the terminal, in order to minimize the power loss on the charging cable and improve the charging efficiency, the length of the charging cable matched with the mobile power supply is usually short. At the same time, for easy carrying, the charging interface is usually hidden, that is, the charging interface is exposed when charging is needed. For example, CN214543688U discloses a mobile power supply with a rotary interface, including a lower cover, an upper cover and a rotary interface. A plurality of first clamping platforms are arranged on the lower cover. The lower cover is also provided with a shaft hole and a storage groove. The rotary interface is rotationally connected to the lower cover through the cooperation of a shaft and the shaft hole. A discharge interface is arranged on the rotary interface. When in use, the rotary interface is rotated, and then the mobile phone is inserted for use. After use, the rotary interface is reset to hide the discharge interface into the storage groove.

[0004] However, after the above mobile power supply is used, although the discharge interface is hidden in the storage groove, the bent section of the rotary interface still protrudes from the upper cover and the lower cover, affecting the appearance, and is easily scratched during the carrying process. Seriously, the bent section of the rotary interface may even be damaged, resulting in electric leakage. Summary of the Utility Model

In addition, the terms such as "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0031] This embodiment relates to a mobile power supply with a rotary interface. Referring to Figure 1 and Figure 2 , it includes a housing 10, a storage groove 20, a rotary interface 30 and a locking mechanism 40. Among them, the inside of the housing 10 has a receiving cavity. The storage groove 20 is opened on one side of the housing 10, and one end of the storage groove 20 communicates with the receiving cavity. The rotary interface 30 is rotatably arranged in the storage groove 20 and can be rotated relative to the storage groove 20 to be exposed outside the housing 10 or accommodated in the storage groove 20.

[0032] The rotary interface 30 includes a housing 31 rotatably arranged in the storage groove 20 and a discharge terminal 32 arranged on the housing 31. The housing 31 is made of plastic material. The discharge terminal 32 cooperates with a charging interface 50 on a mobile communication device such as a mobile phone or a tablet to charge the mobile communication device such as a mobile phone or a tablet. Both sides of the housing 31 are provided with rotating shafts 311. The two rotating shafts 311 are located at the communication part of the storage groove 20 and the receiving cavity, and both rotating shafts 311 extend into the receiving cavity.

[0033] The locking mechanism 40 is arranged in the receiving cavity and is used to lock the rotating shaft 311 so that the rotary interface 30 can be stably accommodated in the storage groove 20 or exposed outside the housing 10.

[0034] During use, by driving the rotary interface 30 to rotate relative to the storage groove 20, the discharge terminal 32 of the rotary interface 30 is exposed outside the housing 10. At this time, the mobile communication device such as a mobile phone or a tablet can be charged through the discharge terminal 32. The rotating shaft 311 is locked by the locking mechanism 40, that is, the rotation angle of the rotary interface 30 is locked, so that the discharge terminal 32 can stably charge the mobile communication device such as a mobile phone or a tablet. When not in use, by resetting the rotary interface 30, and under the action of the locking mechanism 40, the rotary interface 30 is stably received in the storage groove 20.

[0035] Furthermore, referring to Figure 3 , Figure 4 and Figure 5The locking mechanism 40 includes a tooth groove 41 arranged on the rotating shaft 311, a convex gear 42 used to cooperate with the tooth groove 41, and an elastic member used to provide elastic force to the convex gear 42 so that the convex gear 42 and the tooth groove 41 are tightly matched, wherein the tooth groove 41 is located at one end of the rotating shaft 311 away from the housing 31, the tooth groove 41 is located in the accommodating cavity, and the convex gear 42 is meshed with the tooth groove 41.

[0036] The elastic member continuously provides elastic force to the convex gear 42, so that the convex gear 42 can tightly cooperate with the tooth groove 41 on the rotating shaft 311, thereby locking the rotating shaft 311, that is, locking the rotation angle of the rotating interface 30, and then the rotating interface 30 can be stably accommodated in the storage groove 20 or exposed from the shell 10.

[0037] Furthermore, the elastic member includes a spring 43, which is arranged on the side of the convex gear 42 away from the rotating shaft 311. The convex gear 42 is provided with a convex column 421 for cooperating with the spring 43, and one end of the spring 43 is pressed against the accommodating cavity, and the other end of the spring 43 is pressed against the convex gear 42.

[0038] The spring 43 continuously provides elastic force to the convex gear 42 , so that the convex gear 42 can be closely matched with the tooth groove 41 . The spring 43 is easy to obtain and has low cost, which can reduce the production cost.

[0039] Furthermore, the locking mechanism 40 also includes a clamping member for clamping the convex gear 42 against the inner wall of the shell 10, and the clamping member includes a clamping cover 44 and a clamping screw 45 for easily fixing the clamping cover 44 to the shell 10. The clamping cover 44 has a clearance groove 441 for the outer shell 31 to rotate and a limiting groove 442 for limiting the rotating shaft 311, the convex gear 42 and the spring 43.

[0040] By disposing the abutting cover 44 , the rotation shaft 311 , the convex gear 42 and the spring 43 are limited and fixed, so that the rotation interface 30 can stably rotate relative to the receiving slot 20 , thereby improving the stability of the rotation interface 30 .

[0041] Furthermore, the number of tooth grooves 41 on the rotating shaft 311 is four, and the four tooth grooves 41 are evenly arranged along the circumferential direction of the rotating shaft 311, and the convex gear 42 is a four-speed convex gear 42. By setting the number of tooth grooves 41 to four, and the convex gear 42 to a four-speed convex gear 42, the rotation angle of the rotating shaft 311 can be locked from four gears, that is, the four angles of the rotating interface 30 can be locked, and then mobile communication devices such as mobile phones and tablets can be charged from multiple angles for convenient use. In other embodiments, the tooth grooves 41 can also be set to other numbers, and it is only necessary to adjust the convex gear 42 at the same time, and no further limitation is made here.

[0042] Further, a battery and a circuit board (not shown in the figure) are disposed in the accommodating cavity. The battery and the circuit board are electrically connected, and the rotary interface 30 is electrically connected to the circuit board. Through the above arrangement, the rotary interface 30 can stably charge mobile communication devices such as mobile phones and tablets.

[0043] Further, in combination with Figure 1 , a charging interface 50 electrically connected to the circuit board is disposed on the housing 10 to charge the battery through the charging interface 50.

[0044] Further, the housing 10 includes an upper shell 11 and a lower shell 12. The top of the lower shell 12 is provided with an arc transition, and both the storage groove 20 and the rotary interface 30 are located on the upper shell 11. Through the above arrangement, when the housing 10 is placed normally, the charging interface 50 is located on the bottom side of the housing 10, so that the rotary interface 30 can be better hidden. At the same time, the top of the upper shell 11 is provided with an arc transition and has no sharp edges, which is not easy to cause damage to the human body or the outside.

[0045] The above is only used to illustrate the technical solution of the present invention and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
