Is electrically connected with the electric equipment through the power interface 111. The user can start and shut down the portable power source 10 through the operation panel 110, and observe the remaining power of the battery 20 through the operation panel 110.

Referring to fig. 2 and 4, the power module 400 includes a power adapter 410 and two metal sliding rails 420, the power adapter 410 is inserted into the operation box 100, the metal sliding rails 420 are located in the inner cavity 210, the two metal sliding rails 420 are electrically connected with the power adapter 410, the two metal sliding rails 420 are not contacted with each other, the axes of the two metal sliding rails 420 are coincident, i.e. the installation positions of the two metal sliding rails 420 are located on the same straight line, and the two metal sliding rails 420 are not contacted with each other;

referring to fig. 4 and 7, two metal sliding rails 420 are respectively attached to a positive electrode 21 and a negative electrode 21 on the battery, when the electrodes 21 are in contact with the metal sliding rails 420, the battery 20 is electrically connected with the power adapter 410, each metal sliding rail 420 is provided with a sliding groove 421, a sliding block 430 is arranged in each sliding groove 421, a threaded hole 431 is formed in each sliding block 430, after the electrodes 21 are attached to the metal sliding rails 420, a screw is inserted into the electrodes 21, the screw 30 is in threaded connection with the threaded holes 431, and the two cooperate to fix the electrodes 21 on the metal sliding rails 420 (as shown in fig. 8).

The metal sliding rail 420 and the electrode 21 are attached to each other, so that the battery 20 and the power adapter 410 are electrically connected, the metal sliding rail 420 extends along the long side direction of the battery 20, the length of the metal sliding rail 420 is longer than that of the electrode 21, and the contact area is prolonged through the metal sliding rail 420, so that the upper electrode 21 of the battery can still be electrically connected with the power adapter 410 after the battery 20 is replaced by different batteries. Specifically, the length is 1/3 of the length of the power adapter 410, so that 2/3 of the area of the power adapter 410 along the long side can be used to attach to the electrode 21, and the adapting capability of the portable power supply 10 to the storage battery 20 is improved.

The principle of replacing the battery 20 with the portable power source 10 will be described below:

loosening the screw 30 on the sliding cover 300, taking off the sliding cover 300, unlocking the old storage battery 20, and taking out the aged storage battery 20 from the operation port;

the side of the new storage battery 20 with the electrode 21 faces the inner cavity 210 (shown in fig. 3), the storage battery 20 is pushed to enter the inner cavity 210 until the electrode 21 is attached to the metal sliding rail 420 (shown in fig. 4), at this time, the matching state of the electrode 21 and the sliding block 430 in the sliding groove 421 is shown in fig. 5, and the threaded hole 431 in the sliding block 430 is staggered with the mounting hole 22 in the electrode 21;

the screwdriver is inserted into the sliding groove 421, the sliding block 430 is shifted, the sliding block 430 is pushed to the electrode 21 until the threaded hole 431 coincides with the mounting hole 22 (as shown in fig. 6), and the electrode 21 is locked on the metal sliding rail 420 through the screw 30.

And finally, the sliding cover 300 is covered, and the storage battery 20 is replaced.

Wherein a fluorescent coating is provided on the outer wall of the slider 430. The fluorescent coating on slider 430 causes slider 430 to glow in a dark environment allowing the user to view the position of slider 430 to facilitate adjusting slider 430 to electrode 21.

Preferably, when the length of the slider 430 is smaller than that of the electrode 21, the driver is not enough to toggle the slider 430 by the screwdriver to make the threaded hole 431 coincide with the mounting hole 22, in order to solve the above problem, the slider 430 is a magnetic slider 430, so after pushing the slider 430 into the back of the electrode 21, the driver can be abutted against the electrode 21, the slider 430 is attracted by the driver under the action of magnetic force, the driver is moved, the slider 430 slides along with the driver under the action of magnetic force until the threaded hole 431 coincides with the mounting hole 22, and the step of locking the electrode 21 is simplified by withdrawing the driver.

Referring to fig. 8, an opening 422 is disposed on a side of the chute 421 near the operation opening. The width of the opening 422 is smaller than the width of the slider 430, so that the slider 430 can be prevented from being separated, and the width of the opening 422 is larger than the aperture of the threaded hole 431, so that the screw 30 can pass through conveniently.

Referring to fig. 5, a blocking protrusion 423 is disposed in the sliding slot 421, and the blocking protrusion 423 is located at the end of the sliding slot 421. The blocking protrusion 423 is located at the end of the sliding groove 421, and the sliding block 430 is blocked by the blocking protrusion 423 when sliding to the end of the sliding groove 421, so as to prevent the sliding block 430 from being separated from the sliding groove 421.

In one embodiment, referring to fig. 1, a handle 120 is disposed on an outer wall of the operation box 100. The handle 120 is rotatably provided on the operation box 100 so as to be portable by a user.

In one embodiment, referring to fig. 2 and 4, a guiding strip 211 is disposed in the inner cavity 210, and the guiding strip 211 is used for adhering to the outer wall of the battery 20. The guide bars 211 provide support and positioning for the battery 20, and the position of the battery 20 in the cavity 210 is limited by the guide bars 211.

Referring to fig. 1 and 2, an anti-slip stripe 310 is disposed on an edge of the sliding cover 300, and roughness of the edge of the sliding cover 300 is increased by the anti-slip stripe 310, so as to facilitate the disassembly and assembly of the sliding cover 300.

In summary, the two metal sliding rails 420 increase the contact area between the electrode 21 of the battery 20 on the power adapter 410, so that after the batteries 20 with different specifications are placed in the inner cavity 210, the electrode 21 of the battery can be contacted with the metal sliding rails 420, the sliding grooves 421 are internally provided with the sliding blocks 430, and the sliding blocks 430 are matched with the screws 30 to lock the electrode of the battery 20 on the metal sliding rails 420, so that the portable power supply 10 can be adapted to the batteries 20 with different specifications.
