In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] The following is based on the attached Figure 1 To Attachment Fig. 9 The present invention introduces a portable charging device.

[0038] Specifically, Figure 1 , Figure 3 As shown, this embodiment provides a portable charging device, which mainly includes a body 1 and a charging cable 2. An energy storage device, such as a lithium-ion battery, is provided inside the body 1 for storing electrical energy. The charging cable 2 has a fixed end 201 and a free end 202. The fixed end 201 is connected to the plug interface 11 of the body 1 and is electrically connected to the energy storage device, and the free end 202 is provided with a charging connector 21, such as a USB interface plug, for connecting and charging the device.

[0039] The main body 1 is provided with a fixed structure for detachably connecting with the charging cable 2. In the connected state, the charging cable 2 is connected to the main body 1 through the fixed structure, and the portion between the fixed structure and the fixed end 201 is bent to form a carrying portion 203. The user can fix the portable charging device on the wrist, backpack or clothing through the carrying portion 203 for easy carrying. In the detached state, the charging cable 2 is detached from the fixed structure, and the free end 202 can move freely to connect the device to be charged. In addition, in the detached state, the free end 202 is first passed through an auxiliary fixing structure such as a buckle, and then the charging cable 2 is connected to the main body 1 through the fixed structure, so that the carrying portion 203 and the buckle can be buckled and connected, so that the charging cable 2 plays the role of a binding rope and a hanging rope, thereby facilitating carrying. Exemplarily, the auxiliary fixing structure includes a luggage handle, a computer bag handle, a trouser loop, and the like.

[0040] The portable charging device arranges a fixed structure on the main body 1 to fix the fixed end 201 of the charging cable 2 to the main body 1, and the charging cable 2 is detachably connected to the main body 1 through the fixed structure, so that the charging cable 2 can be freely bent to meet the charging needs, and can also form a carrying part 203 to replace the effect of a binding rope or a hanging rope. On the basis of meeting the needs of outdoor or mobile charging, the convenience of carrying is greatly improved.

[0041] Preferably, in this embodiment, the charging cable 2 is connected to the fixed structure by a snap connection. The snap connection operation is convenient and quick, which can not only realize the mutual fixation between the charging cable 2 and the fixed structure in the connected state, but also facilitate the detachment to change from the connected state to the detached state, and has a better user experience. Of course, in some other embodiments, other methods such as threaded connection and magnetic connection can also be used to achieve a detachable connection, which also falls within the scope of protection of the utility model.

[0042] Preferably, in this embodiment, the charging connector 21 on the charging cable 2 is snap-connected to the fixed structure. It should be noted that the charging connector 21 is harder than the wire body 22 of the charging cable 2 and does not need to be bent, so it is easy to set a protruding or recessed structure on the outside of the charging connector 21 to meet the connection needs of the snap connection and at the same time meet the needs of accommodating the internal chip. Optionally, threaded holes, threaded connectors, magnetic suction parts, and clamping fixtures can also be set to meet the needs of other connection methods such as threaded connection and magnetic connection.

[0043] Of course, in some other embodiments, the above-mentioned protruding or recessed structures, threaded holes, threaded connectors, magnetic suction components, clamping fixtures, etc. may also be provided on the wire body 22 of the charging cable 2 to meet the needs of other connection methods such as snap connection, threaded connection or magnetic connection, which also fall within the scope of protection of the present utility model.

[0044] Specifically, Figures 4 to 7 As shown, the fixing structure includes a clamping slot 12 and a protrusion 13, and the protrusion 13 is arranged on the inner wall surface of the clamping slot 12. In the disengaged state, the charging connector 21 can enter the clamping slot 12 through the notch of the clamping slot 12 and change to the connected state. In the connected state, the protrusion 13 can abut against the charging connector 21 to limit the charging connector 21 in the clamping slot 12.

[0045] It should be noted that the charging connector 21 can be inserted into the fixed structure along the width direction, thickness direction or length direction of the charging connector 21, and the present invention does not specifically limit this, as long as a connection state can be formed. In this embodiment, the charging connector 21 enters the card slot 12 along its thickness direction, and in some other embodiments, it can also enter the card slot 12 along the width direction or thickness direction, which all belong to the scope of protection of the present invention.

[0046] like Figure 4 , Figure 6 and Figure 7 As shown, the protrusion 13 includes a first protrusion 131, which is disposed on the side wall 121 of the card slot 12 and is disposed at a preset distance from the bottom wall 122 of the card slot 12. Part of the charging connector 21 can enter and be limited between the first protrusion 131 and the bottom wall 122 of the card slot 12. When in use, the charging connector 21 is first inserted into the card slot 12 through the notch of the card slot 12, and then the charging connector 21 is pushed or pulled toward the first protrusion 131 along the length direction of the charging connector 21, so that the charging connector 21 is inserted between the first protrusion 131 and the bottom wall 122 of the card slot 12, and the charging connector 21 can be limited and fixed in the card slot 12 along its thickness direction (i.e., the direction perpendicular to the bottom wall 122 of the card slot 12), and the charging connector 21 is fixed along the force direction of the charging connector 21 (the force direction here specifically refers to the direction of tension when the charging cable 2 is used as a hanging rope, as shown in FIG. 2 ). Figure 2 , Figure 3 The charging connector 21 is fixed in the card slot 12 by fixing it with the line segment Z in the figure.

[0047] Optionally, the width of the clamping slot 12 is gradually reduced from the end away from the fixed end 201 to the end close to the fixed end 201, so that when the charging connector 21 moves along its length direction to between the first protrusion 131 and the bottom wall 122 of the clamping slot 12, it can be clamped and fixed by the two side walls 121 of the clamping slot 12, thereby achieving simultaneous fixation along the force direction and thickness direction of the charging connector 21. Of course, it is also possible that the distance between the first protrusion 131 and the bottom wall 122 of the clamping slot 12 is gradually reduced as it approaches the fixed end 201, so that when the charging connector 21 moves along its length direction to between the first protrusion 131 and the bottom wall 122 of the clamping slot 12, it can be clamped and fixed by the first protrusion 131 and the bottom wall 122 of the clamping slot 12, thereby achieving simultaneous fixation along the force direction and thickness direction of the charging connector 21, which also falls within the scope of protection of the utility model.

[0048] Continue to refer to Figures 6 to 9 As shown, an opening 123 is provided at one end of the clamping slot 12 close to the fixed end 201, and in the connected state, a portion of the wire body 22 of the charging cable 2 is located in the opening 123. Through the opening 123, the bending state of the wire body 22 can be optimized, and the portion of the wire body 22 close to the charging connector 21 can be prevented from bending in the connected state, thereby preventing the portion of the wire body 22 from cracking or breaking, thereby ensuring the service life and safety of the charging cable 2.

[0049] Preferably, the protrusion 13 also includes a second protrusion 132, which is disposed on the side wall 121 and the bottom wall 122 of the clamping groove 12, and defines the above-mentioned opening 123. In the connected state, the second protrusion 132 can be limitedly abutted against the charging connector 21 along the direction in which the wire body 22 passes through the opening 123, thereby cooperating with the above-mentioned first protrusion 131 to simultaneously fix the charging connector 21 along the force direction and thickness direction of the charging connector 21. Of course, in some other embodiments, the second protrusion 132 can also be only disposed on the side wall 121 or the bottom wall 122 of the clamping groove 12, and this is not specifically limited in the present utility model.

[0050] When in use, the charging connector 21 completes the transition from the disconnected state to the connected state in an L-shaped motion trajectory, that is, it first enters the clamping slot 12 along its thickness direction, and then moves along its length direction toward the direction close to the fixed end 201, so that the charging connector 21 is limited and fixed in the clamping slot 12 by the protrusion 13. Similarly, when it is necessary to change from the connected state to the disconnected state, the charging connector 21 is first moved along its length direction toward the direction away from the fixed end 201, so that the charging connector 21 is separated from the protrusion 13, and then the charging connector 21 can be taken out of the clamping slot 12 along its thickness direction, so as to facilitate charging.

[0051] Preferably, if Figure 5 , Fig. 9 As shown, the two side walls 121 of the engaging slot 12 are further provided with limiting portions 14. In the connected state, the protrusion 13 can be limitedly abutted against one end of the charging connector 21, and the limiting portion 14 can be limitedly abutted against the other end of the charging connector 21 in a relatively clamping manner, thereby further enhancing the stability of the charging connector 21 in the engaging slot 12 and preventing uncontrolled detachment in the connected state.

[0052] Alternatively, if Figure 5 As shown, a guiding slope 125 is provided at one end of the card slot 12 away from the fixed end 201 , and the guiding slope 125 can guide the user to insert the charging connector 21 into the card slot 12 in a blind operation, thereby completing the transition from the disengaged state to the connected state.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
