Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

The embodiment of the utility model provides a:

as shown in fig. 1-6, the portable energy storage device includes a housing 1, a battery compartment 4 is disposed on the housing 1, a battery 2 is inserted into the battery compartment 4, and an automatic locking structure 3 is further disposed in the housing 1. In this embodiment, there are two battery compartments 4, two batteries 2, and two automatic locking structures 3 are correspondingly disposed. The two battery compartments, the battery and the automatic locking structure have the same structure and are arranged in parallel, so that one of the battery compartments, the battery and the automatic locking structure are taken as an example and described as follows.

The outer end of the battery 2 is provided with a hand-buckling groove 21 for facilitating the push-pull operation, the upper side of the battery 2 close to the inner end is provided with a locking groove 22, and the locking groove 22 is formed by sinking downwards.

The automatic locking structure 3 comprises a hinged support 32, a lock tongue 31, a link mechanism and a linear driving piece, wherein the linear driving piece adopts an electromagnet 36. The locking arm 311 of the locking tongue 31 is hinged on the hinge base 32, the locking tongue 31 can rotate, and the end 312 of the locking tongue 31 is used for being in limit fit with the locking groove 22. The hinged support 32 is disposed outside the battery compartment 4 and above the battery compartment 4, and the compartment wall 41 of the battery compartment 4 is provided with an opening for the end 312 of the locking tongue 31 to extend into.

The link mechanism comprises a horizontal connecting rod 35, a swinging connecting rod 34 and a hinged connecting rod 33, wherein the horizontal connecting rod 35 is driven by an electromagnet 36 to realize linear movement.

The horizontal connecting rod 35 is hinged with one end of the swinging connecting rod 34, the other end of the swinging connecting rod 34 is hinged with one end of the hinged connecting rod 33, and the other end of the hinged connecting rod 33 is hinged with the hinged support 32. The other end of the hinge link 33 is provided with a pulling portion 331, the pulling portion 331 is located below the lock arm 311 of the latch tongue 31, and the pulling portion 331 is used for driving the lock arm 311 to swing upward around its hinge axis to release the engagement with the lock groove 22. The pulling portion 331 is formed by extending an end of the hinge link 33 near the hinge base 32, and the pulling portion 331 pushes up the lock arm 311 when the pulling portion 331 rotates upward with the hinge link 33.

The end 312 of the latch tongue 31 is inclined with respect to the lock arm 311 to facilitate contact with the battery 2 during the mounting process.

The horizontal link 35 is inserted into the guide seat 38 to guide the linear movement. The horizontal connecting rod 35 is sleeved with a return spring 37, and the return spring 37 is used for providing the force for returning the horizontal connecting rod 35 after the electromagnet 36 is powered off. In other embodiments, the horizontal connecting rod can be directly driven to act by the air cylinder, and the return spring can be omitted without adopting an electromagnet. The operation of the cylinders is also controlled by the battery management system.

The ejection means that the battery 2 protrudes a distance out of the housing 1, rather than falling directly off the housing 1.

The utility model discloses a portable energy memory's application method:

when the battery 2 is installed, the inner end of the battery is aligned to the bin opening of the battery bin 4 and pushed inwards, and when the battery 2 is installed in place, the charging and discharging port at the inner end of the battery 2 is just inserted into the socket at the rear part of the battery bin 4, so that the conductive connection is completed. The upper side of the battery 2 touches the end 312 of the bolt 31, so that the bolt 31 rotates along with the end to give way to the battery 2. After the battery 2 is in place, the end 312 of the bolt 31 is inserted into the locking groove 22 of the battery 2 to realize the limit, and the battery 2 cannot be separated. When the battery 2 needs to be popped up, the electromagnet 36 can be powered to act by using an operation key on the energy storage device and a signal is given to the electromagnet 36 by using a management system of the battery 2, and the horizontal connecting rod 35 and the return spring 37 are pressed to store energy. The horizontal link 35 finally drives the hinge link 33 to rotate, the lifting portion 331 of the end 312 of the connecting link rotates to jack up the lock arm 311 of the latch 31, the end 312 of the latch 31 is separated from the lock groove 22 of the battery 2, the limit of the battery 2 is released, and the battery 2 is ejected by the ejection spring. And the return spring 37 provides the force for returning the horizontal connecting rod 35 after the electromagnet 36 is powered off, and finally the bolt 31 is returned.
