With the continuous expansion of the battery application field, the market demand thereof is also continuously expanding.

The battery comprises battery monomers, and in order to save the transportation cost, a plurality of battery monomers are packaged and fixed by using a packaging and transporting device, and then a plurality of packaging and transporting devices are stacked, so that the larger transportation load capacity is achieved, and the transportation cost is saved. However, the conventional packing and transporting device can fix only the battery cells having a specific lateral size, and has poor versatility.

In order to alleviate the problem of poor universality of the packaging and transporting device, the applicant has conducted intensive studies and has designed a novel packaging and transporting device.

Referring to fig. 1, fig. 2 and fig. 3 together, fig. 1 is a schematic structural diagram of a packaging and transporting device according to some embodiments of the present application, fig. 2 is an exploded view of the packaging and transporting device according to some embodiments of the present application, and fig. 3 is a cross-sectional view of the packaging and transporting device according to some embodiments of the present application. The packaging and transporting device 100 disclosed in the embodiments of the present application may be used for packaging and fixing battery cells, but not limited to, parts in the battery cells, non-battery cells in various fields, and the like. The battery unit, the parts in the battery unit, and the non-battery unit in each field are all in the form of a to-be-packaged piece 500 that can be packaged and fixed by the packaging and transporting device 100, and for convenience of description, the following embodiments take the to-be-packaged piece 500 as the battery unit for illustration.

In a first aspect, the present application provides a package shipping apparatus 100 comprising a first package 10 and a second package 20. The second package 20 is detachably coupled to the first package 10, and a plurality of fixing portions 21 for inserting the package 500 are formed on the second package 20. Wherein the second packages 20 are at least two, and the cross-sectional areas of the fixing portions 21 on the second packages 20 of different kinds are different.

Specifically, the first package 10 functions to support the second package 20, and the second package 20 functions to package and fix the package 500 to be packaged. In order to facilitate recycling of the packaging and transporting device 100 and to satisfy the requirement of the transfer strength, the first package member 10 and the second package member 20 may be formed of plastic having excellent impact resistance, such as ABS resin (terpolymer of acrylonitrile, butadiene and styrene), PP (polypropylene), and the like. Of course, in other embodiments, the materials of the first package 10 and the second package 20 are not limited to plastics, but may be cardboard, metal, etc., so long as the first package 10 and the second package 20 can be reused.

In order to facilitate stacking of the package transporting device 100, the first package member 10 and the second package member 20 are formed in a shape that enables stable stacking, such as a square shape, a cylindrical shape, and the like.

The second package 20 may be detachably fixed to the first package 10 by a snap-fit, screw-fit, or the like. The fixing portion 21 on the second package 20 may be provided as a through hole, a blind hole, a groove, or other structures that can be used to insert and hold the package 500.

The cross section of the fixing portion 21 refers to a cross section of a space for inserting the package 500 on the fixing portion 21. The cross-sectional area of the fixing portion 21 refers to an area of a cross-section of a space for inserting the package 500 on the fixing portion 21. For example, taking the fixing portion 21 as a circular through hole as an example, the cross section of the fixing portion 21 is circular, and the cross sectional area of the fixing portion 21 is the area of the circular cross section. For another example, taking the fixing portion 21 as a square groove, the cross section of the fixing portion 21 is square, and the cross section area of the fixing portion 21 is the area of the square cross section.

Specifically, the cross-sectional shape of the fixing portion 21 is set according to the cross-section of the package 500 to be packaged, which is commonly used for package transportation. For example, taking a battery cell in which the to-be-packaged member 500 is cylindrical as an example, the cross section of the fixing portion 21 is set to be circular, and taking a battery cell in which the to-be-packaged member 500 is triangular as an example, the cross section of the fixing portion 21 is set to be triangular. The following embodiments will be described by taking a case in which the cross section of the fixing portion 21 is circular and the fixing portion 21 is used to insert a cylindrical battery cell as an example. And it should be ensured that when the to-be-packaged member 500 is inserted into the fixing portion 21, the to-be-packaged member 500 can be clamped with the fixing portion 21, so that the second package member 20 can fix the to-be-packaged member 500.

In actual assembly, for the package 500 having a certain length, the package 500 is inserted into the fixing portion 21 along its longitudinal direction and is caught with the fixing portion 21. For example, taking a cylindrical battery cell as an example of the to-be-packaged member 500, the battery cell is inserted into the fixing portion 21 along the longitudinal direction thereof and is clamped with the fixing portion 21. The longitudinal insertion is such that more packages 500 to be packaged can be provided per unit area of the second package 20, and the packing volume ratio of the packing and transporting device 100 is also higher, the loading amount of a single transportation is also larger.

The fixing portions 21 on the second package 20 of the same kind have the same cross-sectional area, and the fixing portions 21 on the second package 20 of the same kind serve to fix the packages 500 to be packaged of the same lateral size. The lateral dimension of the package 500 refers to the largest dimension of the package 500 in the lateral direction perpendicular to the longitudinal direction thereof. Taking the cylindrical battery cell as the example of the package 500, the lateral dimension of the cylindrical battery cell refers to the diameter of the cylindrical battery cell. Taking the square battery cell as the example of the package 500, the lateral dimension of the square battery cell refers to the width of the battery cell in the direction (the length of the square battery cell is greater than the width, and the width of the square battery cell is greater than the thickness). The cross-sectional areas of the fixing portions 21 on the different kinds of second packages 20 are different, and the different kinds of second packages 20 can be used to fix the packages 500 to be packaged of different lateral sizes.

Depending on the lateral dimensions of the package 500, a second package 20 having a fixing portion 21 that can be matched with the lateral dimensions of the package 500 is selected to be coupled to the first package 10 to fix the package 500. In this way, the packaging and transporting device 100 can fix the to-be-packaged pieces 500 having different lateral dimensions, and has better versatility, and the higher the utilization rate of the packaging and transporting device 100.

The overlapping edge 23 may overlap the surface of the first package 10 where the opening is formed, or the overlapping edge 23 may be spaced from the first package 10, and may be specifically set as required.

It will be appreciated that the flap 23 is always located outside the first package 10 when the second package 20 is retained within the first package 10, so that it is convenient to hold the flap 23 and to lift the second package 20 to remove the second package 20 from the first package 10.

In some embodiments of the present application, the package carrier 100 further includes a stopper 30, where the stopper 30 is disposed within the first package 10 and on a side of the second package 20 facing away from the opening thereof; the limiting piece 30 is provided with a plurality of limiting concave parts 31 for limiting the to-be-packaged piece 500, the limiting concave parts 31 are in one-to-one correspondence with all the fixing parts 21, and each fixing part 21 is of a through hole structure.

Specifically, the limiting member 30 may be retained in the first package 10 and spaced from both the bottom wall of the first package 10 and the bottom wall of the second package 20. Or the limiting piece 30 may be fixedly connected with the bottom wall of the first package 10 or the bottom wall of the second package 20, and may be specifically set according to needs.

Wherein, the limit concave part 31 can be a through hole, a blind hole, a groove and the like. The structure of the limit concave portion 31 is the same as or similar to that of the fixing portion 21.

In actual assembly, the to-be-packaged member 500 inserted into the fixing portion 21 is operated to penetrate the bottom wall of the second package member 20, and further the to-be-packaged member 500 is operated to continue to slide in a damped manner in a direction toward the stopper 30 until the to-be-packaged member 500 is inserted into the stopper recess 31 corresponding to the fixing portion 21.

By providing the stopper 30, the to-be-packaged member 500 inserted in the corresponding fixing portion 21 and the stopper recess 31 is not easy to shake and topple over relative to the packaging and transporting device 100. In this way, the risk of collision of the packages 500 to be inserted in the adjacent fixing portions 21 due to shaking is reduced, so that the risk of breakage of the packages 500 to be packaged during transportation is reduced. In addition, taking the to-be-packaged piece 500 as a battery monomer as an example, the to-be-packaged piece 500 inserted in the corresponding fixing portion 21 and the limiting concave portion 31 is not easy to shake relative to the packaging and transporting device 100, and the risk that the to-be-packaged piece 500 inserted in the adjacent fixing portion 21 causes friction damage between the poles of the adjacent battery monomer due to shake can be reduced, so that the reliability of transportation is improved.

Taking the to-be-packaged member 500 as an example of the battery unit, the buffer member 50 not only separates the to-be-packaged member 500 of the packaging and transporting device 100 and the upper packaging and transporting device 100, but also reduces the possibility that the pole of the to-be-packaged member 500 of the packaging and transporting device 100 contacts with the upper packaging and transporting device 100 and is damaged by friction, thereby having better transportation reliability.

In some embodiments of the present application, the bumper 50 is provided with notches 51 on opposite sides along its length or width.

Wherein the cushioning member 50 is adapted to the shape and size of the opening of the second package member 20. And the two notches 51 on the buffer member 50 may be disposed on two sides of the buffer member 50 along the length direction thereof, or on two sides of the buffer member 50 along the width direction thereof.

The notch 51 is convenient for a user to hold the buffer member 50 at the notch 51, so that the to-be-packaged member 500 can be quickly assembled and disassembled.

The following describes in detail the specific assembly process of the package transporting device 100:

the second package 20 is first smoothly placed on a floor or a table top or the like, then the stopper 30 is bonded to the support 40 to form a composite, and then the composite is bonded to the bottom wall of the first package 10. Then, the second package 20 is clamped in the first package 10, and the plurality of sets of corresponding fixing portions 21 and limiting recesses 31 are sequentially inserted with the packages 500. Taking the battery cell as an example, the same polarity of the poles of all the battery cells in the fixing portion 21 face the same direction, and finally the buffer member 50 is covered in the second package member 20 and covers all the to-be-packaged members 500.

Referring to fig. 4, fig. 5, and fig. 6, fig. 4 is a schematic structural diagram of a stack of two stacking units according to some embodiments of the present application, fig. 5 is a schematic structural diagram of a stacking unit according to some embodiments of the present application, and fig. 6 is a schematic structural diagram of a base of a stacking unit according to some embodiments of the present application.

In a second aspect, the present application further provides a stacking unit 1000, which includes a shoe 200 and a plurality of package transporting devices 100 according to any one of the embodiments, where all package transporting devices 100 are stacked in multiple layers on the shoe 200.

Wherein the shoe 200 mainly functions to carry the package transporting device 100. The shape of the shoe 200 is substantially the same as the shape of the package carrier 100 so that more package carriers 100 can be stacked in a orderly fashion on the shoe 200. For example, taking the package transporting device 100 as a whole with a substantially rectangular shape as an example, the bottom support 200 is also configured with the package transporting device 100 at the bottom layer arranged in a matrix on the bottom support 200.

The stacking unit 1000 includes the multi-layered package transporting devices 100, and the number of the package transporting devices 100 per layer is the same, so that the package transporting devices 100 can be stably stacked. The number of package carriers 100 per layer in the stacking unit 1000 is set according to the size of the shoe 200. For example, taking the case that the bottom bracket 200 and the package transporting device 100 are square, and the side length of the bottom bracket 200 is twice the side length of the package transporting device 100, four package transporting devices 100 may be disposed on each layer of the bottom bracket 200.

In order to improve the space utilization, the number of stacked layers of the package transporting apparatus 100 may be set to 4 or more, or a plurality of stacked units 1000 may be stacked.

By stacking the package transporting device 100 on the bottom support 200, more package transporting devices 100 and the to-be-packaged pieces 500 can be accommodated in a limited space, so that the storage area is greatly reduced, and the space utilization rate is improved.

In some embodiments of the present application, the stacking unit 1000 further includes a clamping member 300, where the clamping member 300 is disposed on the base 200, and a plurality of clamping portions for clamping the bottommost packaging and transporting devices 100 of the stacking unit 1000 are formed on the clamping member 300.

The clamping piece 300 can be fixed by bonding, screwing, clamping and the like with the collet 200, and can be specifically selected according to requirements.

The number of the clamping parts is the same as and corresponds to the number of the packaging and transporting devices 100 at each layer, and each packaging and transporting device 100 at the bottom layer is correspondingly clamped at the corresponding clamping part one by one.

Specifically, the detent 300 has a plate structure, and the detent portion may be a through hole, a blind hole, or a groove. Preferably, the clamping portion is a through hole structure, each packaging and transporting device 100 at the bottom layer is carried on the bottom support 200, and each packaging and transporting device 100 at the bottom layer is penetrated through the corresponding clamping portion and is clamped with the clamping portion.

The positioning portion is arranged, so that the bottommost package transportation device 100 can be stably fixed on the bottom bracket 200, and the risk that the bottommost package transportation device 100 moves on the bottom bracket 200 in the transportation process is reduced. Thus, the package transporting devices 100 of each layer stacked above the lowermost layer can be stably stacked.

In some embodiments of the present application, the stacking unit 1000 further includes an upper cover 400, where the upper cover 400 is disposed on a top side of the topmost package transporter 100 facing away from the bottom bracket 200.

That is, all the package transporting devices 100 are disposed between the bottom bracket 200 and the upper cover 400 between the same stacking units 1000.

In actual stacking, the bottom support 200 is placed on the mounting surface, then the clamping members 300 are fixed on the bottom support 200, and then the lowest packaging and transporting devices 100 are clamped on the corresponding clamping portions one by one. Then, a multilayer package transporting device 100 is stacked on each of the lowermost package transporting devices 100. Thereafter, the upper cover 400 is covered, and the stacking unit 1000 is "well" packed using packing tape. Finally, the entire stacking unit 1000 is wound with a film to reduce interference of external moisture with the package 500.

The upper cover 400 is arranged, the upper cover 400 and the bottom bracket 200 are matched together to semi-seal the package transportation device 100, and the package transportation device 100 positioned between the upper cover 400 and the bottom bracket 200 is less in risk of moving relative to the bottom bracket 200 under the abutting pressure of the upper cover 400. In addition, when a plurality of the stacking units 1000 are stacked, the upper cover 400 may also serve to stably carry the stacking units 1000 thereabove.

In some embodiments of the present application, the upper cover 400 includes a cover 410 and a wrap angle 420, the cover 410 is disposed on a top side of the topmost package transportation device 100 facing away from the bottom support 200, and the wrap angle 420 protrudes from the cover 410 along a direction facing away from the bottom support 200.

The number of wrap angles 420 is the same as and corresponds to the number of corners of the cover 410, and each wrap angle 420 is disposed at a corresponding corner.

The lid 410 cooperates with the shoe 200 to semi-close the package carrier 100, and the package carrier 100 between the lid 410 and the shoe 200 is less likely to move relative to the shoe 200 when the lid 410 is pressed against. In addition, when a plurality of the stacking units 1000 are stacked, the cover 410 may also serve to stably carry the stacking unit 1000 thereabove.

All wrap angles 420 cooperate to enclose and form spacing space, and when a plurality of stacking units 1000 range upon range of setting, stacking unit 1000 that range upon range of on lid 410 can be spacing in spacing space, and wrap angles 420 can reduce the risk of stacking unit 1000 range upon range of on lid 410 relative lid 410 landing.
