Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, the present application provides a blister box 100 for accommodating a plurality of batteries 5. The plastic suction box 100 can be made of plastic, so as to play a certain role in shock absorption and buffer the impact of the outside on the battery 5 during transportation.

The blister pack 100 comprises a first surface 100a (shown in fig. 6), on which first surface 100a projections 10 are provided. The projection 10 includes a second surface 10a remote from the first surface 100 a. The projection 10 includes a first flange 11, a second flange 12, a third flange 13, and a fourth flange 14 connected in this order. The first flange 11 and the third flange 13 are oppositely disposed, and the second flange 12 and the fourth flange 14 are oppositely disposed. The first flange 11, the second flange 12, the third flange 13 and the fourth flange 14 enclose a receiving space (not shown). In some embodiments, the first flange 11 is parallel to the third flange 13. The second flange 12 is parallel to the fourth flange 14 and perpendicular to the first flange 11 and the third flange 13.

The projection 10 further includes a first beam 15 disposed between the first flange 11 and the third flange 13, and the first beam 15 may be plural. The first beam 15 is used to divide the accommodating space into a plurality of accommodating grooves 20, and the accommodating grooves 20 are used to accommodate the batteries 5. Wherein a projection of the first beam 15 in a direction perpendicular to the first surface 100a may be substantially rectangular or square. First beam 15 includes a first side 151 facing first flange 11 and a second side 152 facing pocket 20, and first flange 11 includes a first side wall 111 facing first side 151, and first side 151 is spaced apart from first side wall 111. At least one of the first side 151 or the first sidewall 111 forms a first support button 30. The first support buckle 30 is located outside the receiving groove 20. As shown, the first sidewall 111 is provided with a first support buckle 30.

The first support button 30 is a groove structure formed by recessing the first side 151 or the first sidewall 111. When a plurality of blister packs 100 are stacked, the first support button 30 of one blister pack 100 is used to support an adjacent blister pack 100.

It can be understood that, since the head of the battery usually includes two tabs protruding from the receiving slot, the receiving slot includes a space for separately placing the tabs, so as to prevent the two tabs from contacting the inner wall of the receiving slot and forming an electronic path, and therefore, even if the first supporting buckle is placed in the receiving slot and corresponds to the head of the battery, the first supporting buckle will not damage the head of the battery. However, if the first supporting buckle is disposed in the accommodating groove and corresponds to the tail of the battery, because the first supporting buckle correspondingly forms two edges on the inner wall of the accommodating groove, the edges may impact the battery when the first supporting buckle shakes in the accommodating groove during transportation, which results in the deformation of the tail of the battery due to the sinking of the tail of the battery, and the appearance of the battery is poor.

The first beam 15 is disposed apart from the first flange 11, and the first supporting buckle 30 is disposed on at least one of the first side surface 151 or the first side wall 111, such that the first supporting buckle 30 is located outside the receiving groove 20. Therefore, the flatness of the inner wall of the accommodating groove 20 corresponding to the tail of the battery 5 is improved, and the risk of damage to the tail of the battery 5 can be reduced even if the battery 5 shakes in the accommodating groove 20.

As shown in fig. 1, in some embodiments, the projection 10 further includes a second beam 16 disposed between the second flange 12 and the fourth flange 14. The second beam 16 is shown as only one in fig. 1, however, in other embodiments, the second beam 16 may be multiple and arranged in parallel. The first beam 15 is arranged between the first flange 11 and the second beam 16 and between the second beam 16 and the third flange 13. As shown, the first beam 15 and the second beam 16 may be perpendicular to each other, and the first flange 11, the second flange 12, the third flange 13, the fourth flange 14, the first beam 15 and the second beam 16 together form a lattice structure. Therefore, the first beam 15 and the second beam 16 together divide the housing space into a plurality of housing grooves 20.

Referring to fig. 2, in the case where the battery 5 is a pouch battery, the packaging bag 50 of the battery 5 includes a main body portion 51 for accommodating an electrode assembly (not shown) and a side sealing edge 52 connected to the main body portion 51. The side seal 52 generally includes a ledge 520 protruding from the bottom of the cell 5. The first sidewall 111 is recessed to form a clearance area 1110, and the clearance area 1110 is used for accommodating the lug 520 of the side sealing edge 52. The clearance area 1110 includes a first bottom surface 1111 and a first connection surface 1112 connected between the first bottom surface 1111 and the first sidewall 111, and the first support buckle 30 is located at the first bottom surface 1111.

As shown in fig. 3, further, the first connection face 1112 is perpendicular to the first sidewall 111. That is, the angle θ between the first connection surface 1112 and the first sidewall 111 is equal to 90 degrees. As shown in fig. 4, in other embodiments, the included angle θ between the first connection surface 1112 and the first sidewall 111 may be greater than 90 degrees and less than 180 degrees.

As shown in fig. 1, in some embodiments, at least one of second side 152, the sidewall of second flange 12 facing receptacle 20, or the sidewall of fourth flange 14 facing receptacle 20 forms second support buckle 40. As shown in fig. 1, the second side 152, the sidewall of the second flange 12 facing the receiving slot 20, and the sidewall of the fourth flange 14 facing the receiving slot 20 are provided with the second supporting buckle 40. The second support buckle 40 is a concave structure formed by the second side surface 152, the sidewall of the second flange 12 facing the receiving slot 20, or the sidewall of the fourth flange 14 facing the receiving slot 20. When a plurality of blister packs 100 are stacked, the second support button 40 of one blister pack 100 is used to support an adjacent blister pack 100. The further additional second support buckles 40 improve the support strength of the blister pack 100, and the plurality of first support buckles 30 and the plurality of second support buckles 40 are arranged in a dispersed manner, so that when the plurality of blister packs 100 are stacked, the stress distribution of each layer of blister pack 100 is more uniform, and the risk that the blister pack 100 partially collapses and crushes the batteries 5 placed in the lower layer of blister pack 100 is further reduced.

Referring also to fig. 6, in some embodiments, the first support buckle 30 is substantially a half-circular platform structure. The first supporting buckle 30 includes a second bottom surface 31 and a second connecting surface 32 connected between the second bottom surface 31 and the second surface 10a, the second connecting surface 32 extends from the second surface 10a to the second bottom surface 31 in a direction away from the receiving slot 20, and the second connecting surface 32 is a side surface of the semi-circular truncated cone structure. The second support buckle 40 has a similar structure to the first support buckle 30, and thus, the description thereof is omitted.

As shown in FIG. 2, it can be understood that when second support fastener 40 is disposed on each of two second side surfaces 152 of first beam 15 facing housing channel 20, a minimum width W of top surface 155 of first beam 15 connected between two second side surfaces 152 is defined₁. The total width (i.e. the distance between the two second side surfaces 152) of the first beam 15 is defined as W, and the arc radius of the second support buckle 40 is defined as R₂Then W is not less than W₁+2R₂. The minimum width W of the top surface 155 may be set₁Greater than 4mm, thereby reducing the risk of the first beam 15 collapsing when a plurality of blister packs 100 are stacked.

Further, the total width (i.e. the distance between the two first connection surfaces 1112) of the clearance area 1110 is W₂The radius of the arc of the first support button 30 is defined as R₁The distance between the first connection surface 1112 and the edge of the first supporting buckle 30 is L, then W₂≥2L+R₁。

In other embodiments, as shown in FIG. 5, two second beams of the first beam 15R when only one of the side surfaces 152 is provided with the second support buckle 40₂+W₁＝W。

Referring to fig. 7, another embodiment of the present application further provides a blister box 200. The difference with the blister pack 100 described above is that the first beam 15 further comprises a third side 153 facing the second beam 16. The second beam 16 includes a second side wall 161 facing the third side 153, and the third side 153 is spaced apart from the second side wall 161. At least one of the third side 153 or the second side wall 161 is also recessed to form the first support button 30. As shown, the first support buckle 30 is disposed on each of the third side 153 and the second side 161.

The first supporting buckle 30 is also located outside the receiving groove 20 by disposing the first beam 15 at a distance from the second beam 16 and further disposing the first supporting buckle 30 on at least one of the third side 153 or the second side wall 161. Moreover, the further increased first supporting buckles 30 improve the supporting strength of the plastic uptake box 100, and are beneficial to the dispersed arrangement of the first supporting buckles 30, so that when a plurality of plastic uptake boxes 100 are stacked, the stress distribution of each layer of plastic uptake box 100 is more uniform, and the risk that the plastic uptake box 100 partially collapses and crushes the batteries 5 placed in the lower layer of plastic uptake box 100 is reduced.

In some embodiments, the first beam 15 further comprises a fourth side 154 facing the third flange 13, the third flange 13 comprises a third side wall 131 facing the fourth side 154, and the fourth side 154 is spaced apart from the third side wall 131. At least one of the fourth side 154 or the third side wall 131 is also recessed to form the first support button 30. As shown, the first support buckle 30 is disposed on each of the fourth side 154 and the third side 131.

The first supporting buckle 30 is also located outside the receiving groove 20 by disposing the first beam 15 away from the third flange 13 and disposing the first supporting buckle 30 further on at least one of the fourth side 154 or the third side wall 131. Further, the further addition of the first support button 30 improves the support strength of the blister pack 100. The plurality of first support buttons 30 form a grid structure on the blister pack 100, so that when the plurality of blister packs 100 are stacked, the stress distribution of each layer of blister pack 100 is more uniform, and the risk that the blister pack 100 partially collapses and crushes the batteries 5 placed in the lower layer of blister pack 100 is further reduced.

Referring to fig. 8, an embodiment of the present application further provides a blister pack assembly 300, which includes a plurality of blister packs 100 (or blister packs 200) stacked one on another. The first support button 30 of one blister pack 100 is supported on the second surface 10a of an adjacent blister pack 100. More specifically, the second bottom surface 31 of the first support button 30 of one suction box 100 is supported on the second surface 10a of the adjacent suction box 100. Stacking a plurality of blister packs 100 not only serves to protect the battery, but also can save transportation costs and storage space.

In addition, it is obvious to those skilled in the art that other various corresponding changes and modifications can be made according to the technical idea of the present application, and all such changes and modifications should fall within the protective scope of the claims of the present application.
