[0032] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0033] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0034] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0035] Please refer to Figures 1-4 The embodiment is a small-volume gallium nitride fast-charging charger, which comprises:

[0036] The gallium nitride charging part comprises a charging head 11.

[0037] The charging head 11 is connected with a suitable power adapter to transmit electric energy to the equipment via the wire 13.

[0038] The gallium nitride charging part further comprises a joint one 12, a wire 13, a joint two 14, a pin 15 and an interface 16.

[0039] The interface 16 is arranged in the middle of one end of the charging head 11, one end of the joint one 12 is inserted into the interface 16, one end of the wire 13 is electrically connected with the other end of the joint one 12, one end of the joint two 14 is electrically connected with the other end of the wire 13, and one group of the pins 15 symmetrically penetrates the end of the other end of the charging head 11.

[0040] Interface 16 receives connector 12 and electrically connects the two. Connector 12 serves as one of the power transmission structures. Wire 13 is used for power transmission. Connector 14 receives the transmitted power again and transmits it into the device. Pin 15 connects the charging head 11 to the external power adapter for power transmission.

[0041] The cable storage section includes a positioning groove 21, a positioning block 22, a limiting block 23, and a limiting groove 24.

[0042] Two sets of positioning grooves 21 are symmetrically opened on both sides of the outer surface of the charging head 11, and one end of the positioning block 22 is engaged in the positioning groove 21, the limiting block 23 is sleeved on the other end of the positioning block 22, and the limiting groove 24 is opened through the middle of one end of the limiting block 23.

[0043] The positioning groove 21 supports and installs the positioning block 22, and the positioning block 22 supports and installs the limiting block 23. The limiting block 23 limits the wire 13 that is wrapped around the middle of the outer surface of the charging head 11. The limiting groove 24 then performs a secondary clamping and limiting of the wire 13.

[0044] The limiting groove 24 is arc-shaped, and a rubber pad is adhered to the inner side wall of the limiting groove 24;

[0045] The arc-shaped design meets the requirements for clamping the wire 13, while the rubber pad increases friction to ensure the stability of the clamped wire 13 structure.

[0046] A sleeve 26 is fixed at the middle of the other end of the positioning block 22, and a protruding post fixed at the middle of the other end of the limiting block 23 is sleeved inside the sleeve 26.

[0047] The sleeve 26 and the protruding post are connected to fix the positioning block 22 and the limiting block 23. The sleeve connection method facilitates the assembly and disassembly of the structure.

[0048] A storage sleeve 25 is fixed at the center of the outer side of the limiting block 23;

[0049] The storage sleeve 25 provides external protection for the wrapped and stored connector 14;

[0050] Working principle:

[0051] After making an electrical connection to connector 12 in interface 16 and an electrical connection to connector 14 in the device input terminal, the pin 15 is electrically connected to the external power adapter, and electrical energy is transferred to the device through wire 13 to charge the device.

[0052] When the charging is completed and the charging head needs to be stored, the wire 13 is wrapped around the middle of the outer surface of the charging head 11, and the positioning blocks 22 are pre-locked and fixed in the positioning groove 21. The positioning blocks 22 are fixed by the sleeve between the protrusion and the sleeve 26. The inner side of the limiting block 23 restricts the structure of the stored wire 13, and one end of the wire 13 is locked in the limiting groove 24 for secondary structural restriction. The connector 14 is stored by the storage sleeve 25.

[0053] This step facilitates use and improves the applicability of the structure.

[0054] Please see Figures 1-4 As shown, this embodiment is based on the above embodiment 1, and further includes a water-cooled protection unit;

[0055] The water-cooled protective part includes a protective sleeve 31, a hook and loop fastener 32, and a loop and loop fastener 33;

[0056] The protective sleeve 31 is wrapped around the middle of the outer surface of the charging head 11, and the hook and loop sides 32 and the loop sides 33 are respectively provided at the ends of the protective sleeve 31.

[0057] The protective sleeve 31 provides impact protection for the outer surface of the charging head 11, and after cold water is injected, it can provide water cooling and explosion protection for the charging head 11. The adhesion between the hook side 32 and the hook side 33 of the Velcro provides first-to-first adhesion limitation for the protective sleeve 31, so as to secure it to the outer surface of the charging head 11.

[0058] The protective sleeve 31 has a cavity in the middle, and a plug head 34 is threaded through the lower part of one side of the outer surface of the protective sleeve 31;

[0059] The cavity is used to collect the injected cold water, while the sealing head 34 seals the injection port of the protective sleeve 31 to prevent the injected cold water from leaking out.

[0060] Working principle:

[0061] When using the charging head 11, the protective cover 31 can be wrapped and attached to the surface of the charging head 11 in advance, and the protective cover 31 can be fixed to the outer surface of the charging head 11 by the adhesion between the hook side 32 and the hook side 33 of the Velcro.

[0062] When using the charging head 11 in hot weather, cold water can be injected into the central cavity inside the protective sleeve 31 through the injection port and sealed by the sealing head 34.

[0063] This step provides collision and explosion protection for the charging head 11, saving costs and making it easier to use.

[0064] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
