The push rods 31 at the ends of the pair of clamping arms 3 are oppositely positioned at the top (or upper end) of the charging module, the ends of the push rods are in contact or have a gap, the swing arm 6 is rotated by the motor to swing towards or towards the right, and the push arm 60 at the end of the swing arm simultaneously interacts with the ends of the pair of clamping arms to push the pair of clamping arms 3 to rotate and unlock the corresponding mobile power supply. In this embodiment, the fixing seat 21 for mounting and limiting the power component 200 is a mounting hole structure opened on the housing 1.

In this embodiment, the elastic component 4 is a torsion spring, and is mounted on the rotating shaft 33 of the clamping arm, and the torque of the torsion spring enables the clamping arm 3 to fasten the mobile power supply, and meanwhile, the clamping arm is driven to reset after unlocking.

The working principle of the charging unit 1000 of the present embodiment is: as shown in fig. 5, the portable power source 9 is placed in the charging module 100 before the user rents the portable power source. At this time, the swing arm 6 is attached to the motor rotation shaft 221, and the motor 220 keeps the swing arm 6 in the neutral position. Two the module of charging all contains about two tight arms 3 of clamp, and the tight arm 3 of clamp is in the fastening state under the effort of torsional spring. At this time, the clip 30 at the tip of the clamp arm is inserted into the clip hole 90 of the portable power source, and the portable power source 9 is in a fastened state. As shown in fig. 6, when the user needs to rent the portable power source, the charging device sends a lease instruction to the charging module 100, and when the portable power source on the left needs to be unlocked, the control PCB controls the motor 220 to rotate, and the rotating shaft 221 of the motor drives the swing arm 6 to rotate to the left. One end of the swing arm 6 touches and pushes the end position of the clamp arm 3 and rotates the clamp arm 3 around the rotation shaft 3 by a certain angle. The rotational movement of the clamp arm 3 will cause the clamp arm catch 30 to disengage from the portable power source catch aperture 90 and place the torsion spring in a compressed state. At this time, the mobile power supply 9 is in an unlocked state, and the user is waited to take the mobile power supply away. After the user removes the mobile power source, the motor 220 will rotate in the reverse direction, so that the swing arm is in the neutral position again. The clamp arm 3 also restores the state of fig. 5 under the force of the torsion spring. When the mobile power supply on the right side needs to be rented, the motor 220 rotates reversely, so that the swing arm 6 swings to the right side, and the working principle is the same as that of the charging module on the left side.

It is to be understood that the swing arm 6 may be a detachable member independent of the motor 220, or the rotation shaft 221 of the motor may be formed as a swing arm, so that the swing arm is integrated with the motor. The end of the swing arm is provided with a suitable push arm 60.

In other alternative embodiments, the snap-in charging unit 1000 may also set the number of the movable components 200 to two and collectively arrange the movable components outside the two charging modules 100, that is, the movable components 200 are externally arranged on the charging modules 100 and collectively arranged in the accommodating cavity 2, so as to simplify the structure of the charging unit 1000, facilitate replacement or maintenance of electronic components, and facilitate replacement or maintenance of damaged magnets or motors. In addition, an external electronic component (such as a magnet or a motor) can be sealed, so that the electronic component can be protected.

The two charging modules in the snap-in charging unit 1000 may also be arranged in a head-to-head manner or other manners according to the structure of the charging device, and are not limited to the left-right arrangement in the above embodiment.

In other embodiments, a plurality of charging modules 100 may be disposed in the snap-in charging unit 1000, and the power member 200 is shared to unlock the charging modules, or the power members 200 are collectively disposed outside the housing of each charging module. For example, in the first embodiment, four charging modules 100 are disposed on the housing 1, a receiving cavity 2 is formed in the middle of the four charging modules, and two electromagnetic valves are disposed, so that the four charging modules can be unlocked by applying force to the clamping arms 3 of the four charging modules through the electromagnets 210 and the iron cores 20. For example, the second embodiment is modified, the plurality of charging modules 100 may be arranged according to the rotation track of the swing arm 6 of the power component 200, so that the swing arm 6 rotates by a certain angle under the driving of the motor to respectively push the clamping arm 3 of each charging module to unlock each charging module 100. The push rod 61 at the end of the swing arm 6 may be provided in plurality.

The utility model also provides a charging equipment, including a plurality of charging module 100, a plurality of charging module form between two liang the utility model discloses the buckle formula charging unit 1000 of above-mentioned embodiment, perhaps charging equipment includes the charging unit 1000 of the above-mentioned embodiment of a plurality of. The charging device includes a body, a control center is disposed in the body, and the control center is connected to the control PCBs of the respective buckle-type charging units 1000, and transmits and receives commands to control the operations of the respective control PCBs 500. The control PCB 500 in each charging unit 1000 receives an instruction sent by the control center of the charging device, and controls the operations of the components of the charging module 100 according to the instruction, so that the charging module 100 can complete one or more functions of returning, charging and communicating of the portable power source. The charging device further comprises a communication module, a user instruction input module and the like.
