Description

Technical Field

[0001] The utility model relates to the field of battery backpacks, in particular to a battery backpack. Background Art

[0002] In portable lighting devices such as headlamps, it is troublesome to install a power source inside, so a battery backpack and a charging cable connected to the battery backpack and the headlamp on both sides are often used to provide power.

[0003] A Chinese patent with announcement number CN205609633U discloses a battery backpack, including a rectangular outer shell with an opening at the rear side of the outer shell. A battery inner slot is pressed into the outer shell through the rear opening, and a positive electrode sheet and a negative electrode sheet are tightly inserted into the inner ends of the battery inner slot respectively. A conductive platform protruding inward is die-cast on the positive electrode, and a conductive spring is connected to the inner side of the negative electrode sheet. A charging hole electrically connected to the battery inner slot is installed on the outer shell.

[0004] In the above structure, when the charging hole on the outer shell is connected to a portable lighting device such as a headlamp through a charging cable, since there is no component for fixing the charging cable between the charging hole and the charging cable, the charging cable is easy to fall off from the charging hole during the use of the portable lighting device such as the headlamp, thereby causing the portable lighting device such as the headlamp to lose power and become blind. Utility Model Content

[0005] The utility model provides a battery backpack to solve the problem that the prior art has no fixing components between the charging port and the charging cable, which causes the charging cable to easily fall off from the charging port during the use of headlamps, etc., thereby causing power failure and blindness in portable lighting devices such as headlamps.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A battery backpack comprises a shell and a charging hole provided on the shell for partially inserting a charging cable, an anti-slip component for reducing the probability of the charging cable falling off the charging hole is provided between the shell and the charging cable, the anti-slip component comprises a moving block with a slot movably provided in the shell, an elastic member for driving the slot and the charging hole to be misaligned to clamp the charging cable after the charging cable passes through the slot and is inserted into the charging hole, and a driving member provided on the shell for squeezing the moving block until the slot and the charging hole are aligned to realize the charging cable detaching from the charging hole.

[0008] By adopting the above scheme, the charging cable can be partially inserted into the slot provided on the moving block. After the charging cable is inserted into the slot, the moving block can be driven by the elastic member provided so that the slot on the moving block and the charging hole are misaligned, thereby reducing the probability of the charging cable detaching from the charging hole; and when the charging cable needs to be removed from the charging hole, the slot on the moving block can be driven by the driving member provided to face the charging hole on the shell, and the charging cable can be removed from the charging hole.

[0009] Preferably, the driving member comprises a through hole provided on the housing at an end of the moving block away from the elastic member and a button provided on the end of the moving block away from the elastic member, passing through the through hole and extending outside the housing.

[0010] With the above solution, the slot on the moving block can be driven to face the charging hole by a button, and the charging cable can be inserted into the slot or removed from the charging hole.

[0011] Preferably, the elastic member is a spring, and a housing sleeve for accommodating a compressed spring is protruded from the end of the moving block away from the button, and two ends of the spring are elastically in contact with the bottom of the housing sleeve and the inner wall of the shell respectively.

[0012] By adopting the above scheme, the springs on both sides elastically abutting against the bottom surface of the accommodating sleeve and the inner wall of the shell respectively can drive the moving block to move, so that the slot on the moving block and the charging hole are misaligned. At this time, the moving block can fix the charging cable inserted into the charging hole and the slot on the moving block, thereby reducing the probability of the charging cable detaching from the charging hole.

[0013] Preferably, an anti-deflection component is provided in the housing to prevent the moving block from deflecting when the moving block moves in the housing.

[0014] Preferably, the anti-deflection component includes a limiting groove arranged in the shell, and the width of the limiting groove is equal to the width of the moving block.

[0015] By adopting the above solution, the limit groove is provided for the moving block to slide therein, and the width of the limit groove is set to be the same as the width of the moving block, so that the probability of deflection of the moving block when moving in the limit groove is reduced.

[0016] Preferably, a bite component is provided between the moving block and the charging cable to increase the anti-detachment performance of the charging cable.

[0017] Preferably, the engaging component comprises a card block protruding from a side wall of the slot close to the elastic member, and a card slot for partially inserting the card block is provided on the charging cable.

[0018] By adopting the above solution, the card block can be inserted into the card slot when the card slot on the charging cable is directly opposite to it, thereby further reducing the probability of the charging cable being detached from the charging hole.

[0019] Preferably, the card block is provided with an introduction component which drives the card block to drive the slot on the moving block to face the charging hole when the charging cable is inserted into the slot.

[0020] Preferably, the introduction component comprises an introduction slope provided at one end of the card block away from the elastic member, and the introduction slope is inclined outwardly from the top of the card block to the bottom of the card block.

[0021] By adopting the above scheme, when the charging cable is inserted into the slot on the moving block, the end face of the charging cable will first contact the lead-in slope on the card block. At this time, the charging cable will exert pressure on the lead-in slope, thereby causing the moving block to move downward. At this time, the charging cable can be inserted into the slot on the moving block. When the charging cable moves to the point where the card slot on it is aligned with the card block on the moving block, the elastic member provided at this time will drive the lifting block to rebound and reset. At this time, the card block on the moving block will be partially inserted into the card slot on the charging cable, thereby fixing the charging cable inserted into the charging hole and reducing the probability of the charging cable falling out of the charging hole.

[0022] The utility model adopts the above technical scheme, and has significant technical effects: the charging cable can be partially inserted into the slot provided on the moving block, and after the charging cable is inserted into the slot, the moving block can be driven by the provided elastic member to misalign the slot on the moving block with the charging hole, thereby reducing the probability of the charging cable detaching from the charging hole; and when the charging cable needs to be removed from the charging hole, the slot on the moving block can be driven by the provided driving member to face the charging hole on the shell, and the charging cable can be removed from the charging hole.
