In the housing groove 11, the positioning member 20 is moved in a direction away from the cartridge body 10 by an external force, so that the protruding portion is pulled out from the recessed portion, and the positioning member 20 is separated from the cartridge body 10, thereby releasing the positioning member 20 from being fixed in the housing groove 11, that is, releasing the soft-package battery 200 from being fixed.

In another alternative embodiment, the first connecting portion 12 is a snap (not shown), and the second connecting portion 21 is a first locking groove (not shown) matching with the snap, and the snap is connected with the first locking groove, so that the positioning member 20 can be stably installed in the receiving groove 11, thereby limiting the movement of the pouch battery 200, i.e. the pouch battery 200 is fixed in the receiving groove 11; or, first connecting portion 12 is the draw-in groove (not shown), and second connecting portion 21 is the first buckle (not shown) that matches with the draw-in groove, and the draw-in groove is connected with first buckle to make setting element 20 can firmly install in holding tank 11, thereby restrict laminate polymer battery 200's removal, laminate polymer battery 200 fixes in holding tank 11 promptly.

It should be noted that, with the above technical solution, not only can the positioning element 20 be stably fixed in the accommodating groove 11 to fix the pouch battery 200, but also the subsequent storage or taking of the pouch battery 200 is facilitated. That is, the keeper 20 can be removed from the receiving groove 11 by directly releasing the connection between the first connecting portion 12 and the second connecting portion 21.

In this embodiment, the first connecting portion 12 is a hole disposed on the bottom surface of the accommodating cavity 11, and the second connecting portion 21 is a protrusion disposed on a surface of the positioning element 20 close to the accommodating cavity 11. Wherein, the shape of hole and protruding grain is circular, the shape looks adaptation of hole and protruding grain, and setting element 20 is fixed in holding tank 11 through the mutual grafting cooperation dismantlement formula installation of hole and protruding grain to restriction laminate polymer battery 200's removal, fixed laminate polymer battery 200 promptly.

In addition, in the present embodiment, the diameter of the hole is 1mm to 10mm. Avoid leading to the air in the holding tank 11 not to circulate because of the hole undersize, when box 100 stacks is stored to a plurality of batteries, negative pressure appears in the holding tank 11, causes the adhesion of battery storage box 100. Or, the structure of the case body 10 is loose and the overall strength is low due to the excessive holes, which may cause damage and breakage of the device when the battery storage case 100 is collided.

Of course, in other embodiments, the positioning element 20 can also be detachably mounted in the accommodating groove 11 in other suitable manners, and the shapes of the holes and the protruding particles can also be other shapes such as rectangles, ellipses, triangles, etc., which the present invention does not limit, and those skilled in the art can adaptively adjust.

Further, as a specific embodiment of the battery storage box 100 provided by the present invention, as shown in fig. 2 to fig. 4, in order to improve the stability of the positioning member 20 installed in the accommodating groove 11, the concave portions and the convex portions are arranged in a matrix. On one hand, the convex parts arranged in a matrix manner on the positioning pieces 20 are all embedded into the concave parts, so that the stability of fixing the positioning pieces 20 in the accommodating grooves 11 is improved, and the problem that the quality of the soft package battery 200 is affected due to collision damage of the soft package battery 200 caused by the positioning pieces 20 loosening or falling when the battery storage box 100 collides or bumps is avoided; in another aspect. Through the recessed portions arranged in a matrix form and the protruding portions arranged in a matrix form, the positioning member 20 can be fixed at any position of the bottom surface of the accommodating groove 11, so that the positioning member 20 can adjust the position of installation in the accommodating groove 11 according to the size of the pouch battery 200.

Further, as a specific embodiment of the battery storage box 100 provided by the present invention, as shown in fig. 1 and fig. 4, in order to improve the stability of the positioning member 20 to fix the pouch battery 200, the positioning member 20 is "L" shaped. Specifically in this embodiment, when fixing laminate polymer battery 200 through setting element 20, laminate polymer battery 200 week side arbitrary adjacent two faces and the cell wall looks butt of holding tank 11, two remaining adjacent sides support with the both sides of "L" font setting element 20 mutually to can restrict laminate polymer battery 200's removal, accomplish laminate polymer battery 200's fixing promptly, in order to improve setting element 20 to laminate polymer battery 200 fixed stability.

It should be noted that, in other embodiments, at least two positioning members 20 may be used to respectively abut against four sides of the peripheral side of the pouch battery 200 to limit the movement of the pouch battery 200, that is, to complete the fixing of the pouch battery 200.

In addition, at the corner of the positioning member 20, the positioning member 20 is provided with a clearance groove 22, and the clearance groove 22 is used for protecting the pouch battery 200. It can be understood that when the pouch battery 200 is taken and placed, the empty avoiding groove 22 can prevent the edge of the pouch battery 200 from contacting or colliding with the positioning member 20 to damage the pouch battery 200, thereby improving the quality of the battery.

Further, as the utility model provides a specific implementation of battery storage box 100, as shown in fig. 1 to fig. 3, at least two holding tanks 11 have been seted up on the box body 10, and holding tank 11 is array distribution to improve battery storage box 100's utilization ratio, thereby can improve the production efficiency of product. Specifically in this embodiment, the quantity of holding tank 11 is six, and is the distribution of rectangle array, and when transporting laminate polymer battery 200, this battery storage box 100 can hold six laminate polymer battery 200 simultaneously, improves production efficiency. Of course, in other embodiments, the number of the accommodating grooves 11 may be other, and the present invention does not limit this, and those skilled in the art can adaptively adjust this.

In the present embodiment, the depth of the receiving groove 11 is greater than the thickness of the pouch battery 200, so that the pouch battery 200 can be completely received in the receiving groove 11. It should be noted that the pouch battery 200 is entirely accommodated in the accommodating groove 11, so that the pouch battery 200 can be prevented from being damaged due to unstable stacking and collapse when a plurality of battery storage cases 100 are stacked; secondly, prevent to leak and bump with other external mechanism because of laminate polymer battery 200 in the transportation, cause laminate polymer battery 200 to damage, influence laminate polymer battery 200's quality.
