Description

Technical Field

[0001] The utility model relates to the field of battery packs, in particular to a battery pack with a USB. Background Art

[0002] A Chinese patent with publication number CN210984867U discloses a battery pack, comprising two outer shells that can be interlocked to form a cylinder, one or more batteries installed in the outer shell, and an output port for the battery pack to charge other electronic devices and an input port for charging the battery pack are also provided on the outer shell.

[0003] When the two shells in the above structure are buckled together, one shell needs to be pressed hard to deform the surface of the shell so that its part can be inserted into the other shell. Afterwards, the shells are released to restore to their original state, thereby achieving the buckling between the two to form a cylinder for installing batteries. When the two shells need to be opened, a large force is also required to press one shell to deform it. Since a battery is installed inside the shell, the space for the shell to deform when pressed will also be reduced, thereby further increasing the difficulty of opening the two shells. Utility Model Content

[0004] The utility model aims to solve the problem that the battery pack in the prior art is formed by buckling two shells which can be buckled together, which makes it difficult to splice or separate the two shells. The utility model provides a battery pack with a USB which is easy to open and close.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A battery pack with USB includes two semicircular shells with hollow interiors. The two shells are spliced ​​together to form a cylinder for installing batteries. The side walls of the two shells are hinged to each other through a hinge structure, and a fixing component is provided at one end of the two shells away from the hinge structure to fix the two shells when the ends of the two shells away from the hinge structure are flipped to abut against each other. The fixing component includes telescopic components telescopically arranged at both ends of one shell away from the hinge component and a plug-in component is provided at one end of the other shell away from the hinge component for partial insertion of the telescopic component when the two shells are flipped and spliced ​​into a cylinder. An unlocking component for releasing the fixation between the two shells is also provided on the shell provided with the plug-in component.

[0007] By adopting the above scheme, one end of the two shells are hinged to each other through a hinge structure, and the other ends are fixed to each other through a plug-in component, so that the splicing of the two shells is more convenient. When the two shells need to be spliced ​​together, it is only necessary to flip the shell with the telescopic component so that the telescopic component is partially inserted into the plug-in component on the other shell. At this time, the two shells can be fixed away from one end of the hinge structure; and when the inside of the cylinder needs to be opened, the unlocking component can be used to release the fixation between the telescopic component and the plug-in component. At this time, the ends of the two shells away from the hinge structure can be moved away from each other, making the opening of the cylinder more convenient and labor-saving.

[0008] Preferably, the telescopic component includes a plug-in column, and a receiving hole for completely accommodating the plug-in column when the plug-in column is retracted and a spring for driving the plug-in column to partially extend out of the receiving hole after retracting are respectively provided at both ends of the shell. An introduction component is provided on the plug-in column for driving the plug-in column to retract when the plug-in column abuts against the plug-in component.

[0009] By adopting the above scheme, when the ends of the two shells away from the hinged structure need to be fixed to each other, the shell provided with the plug-in column can be rotated so that the plug-in column gradually abuts against the plug-in component. When the plug-in column abuts against the plug-in component, the introduction component will drive the plug-in column to automatically retract into the accommodating hole. At this time, the shell provided with the plug-in column can continue to flip over. When the ends of the two shells away from the hinged structure abut against each other, the spring will push the plug-in column to be partially inserted into the plug-in component, thereby realizing the fixation of the two shells away from the end of the hinged structure.

[0010] Preferably, the introduction component is an introduction slope arranged at an end of the plug-in column away from the spring.

[0011] By adopting the above scheme, the introduction slope is set so that when the end of the two shells away from the hinge structure is fixed, they abut against the surface of the plug-in component, so that the introduction slope is pressed to push the plug-in column back into the accommodating hole, so that the end of the two shells away from the hinge structure can be smoothly fixed to each other.

[0012] Preferably, the plug-in component comprises two plug-in sockets respectively arranged at the two end portions of a side of the shell away from the hinge structure where no telescopic component is arranged, and plug-in holes for partial insertion of the plug-in column are arranged in the two plug-in sockets.

[0013] By adopting the above solution, the plugging hole arranged on the plugging seat can be partially inserted into the plugging column telescopically arranged on the shell, so as to achieve the fixation of the two shells at one end away from the hinge structure.

[0014] Preferably, the unlocking component includes mounting holes coaxially arranged with the plug-in hole and having a smaller diameter than the plug-in hole, respectively arranged in the two plug-in sockets, and a pushing column with one end extending out of the mounting hole and the other end inserted into the plug-in hole from the mounting hole and pushed into the plug-in hole when the plug-in column moves.

[0015] By adopting the above scheme, the push column can be moved from the installation hole to the inside of the plug-in hole when the inside of the cylinder needs to be opened. At this time, the push column will gradually abut against the surface of the plug-in column and push the plug-in column to move after abutting against the surface of the plug-in column, so that the plug-in column gradually retracts into the accommodating hole. At this time, one end of the two shells can be rotated open.

[0016] Preferably, a limiting component for limiting the insertion of the push column from the mounting hole into the plugging hole is respectively provided between the opposite ends of the two plugging seats and the two push columns.

[0017] Preferably, the limiting component comprises a limiting block provided at an end of the push column away from the plug hole, and a clamp which can be elastically clamped between the limiting block and the surface of the plug socket.

[0018] By adopting the above scheme, the clamp is inserted between the limit block and the surface of the socket. At this time, the push column cannot move into the socket hole, and the socket column inserted into the socket hole will not fall out of the socket hole, thereby enhancing the stability of the fixation between the two shells.

[0019] Preferably, one end of the clamp is hinged to the surface of the socket.

[0020] By adopting the above solution, one end of the clamp is hinged to the surface of the socket, thereby reducing the probability of the clamp being lost when it is not clamped between the limit block and the surface of the socket.

[0021] Preferably, the hinge structure includes hinge seats respectively arranged at two ends of one of the shells and a hinge shaft with one end penetrating through the two hinge seats and the side wall of the other shell.

[0022] By adopting the above solution, the hinge connection between the two shells is realized by inserting the hinge shaft into the shell and the two hinge seats.

[0023] Preferably, a charging port for charging the battery inside the shell and an output port for the battery pack to charge other electronic devices are respectively provided on the side walls of the two shells.

[0024] By adopting the above scheme, people can charge the battery in the barrel through the provided charging port, and when other electronic devices need to be charged, the power in the battery pack can be charged into the electronic devices through the data cable through the output port.

[0025] The utility model has a significant technical effect due to the adoption of the above technical scheme: one end of the two shells are hinged to each other through a hinge structure, and the other ends are fixed to each other through a plug-in component, so that the splicing of the two shells is more convenient. When the two shells need to be spliced ​​together, it is only necessary to flip the shell with the telescopic component so that the telescopic component is partially inserted into the plug-in component on the other shell. At this time, the two shells can be fixed away from one end of the hinge structure; and when the inside of the cylinder needs to be opened, the unlocking component can be used to release the fixation between the telescopic component and the plug-in component. At this time, the ends of the two shells away from the hinge structure can be moved away from each other, thereby making the opening of the cylinder more convenient.

At this time, the push column 11 will gradually abut against the plug-in column 4 and push the plug-in column 4 to move after abutting against it. At this time, the plug-in column 4 will be retracted into the accommodating hole 6. At this time, the shell 1 equipped with the plug-in column 4 can be turned over to open the inside of the cylinder.
