the right tray liner 11 comprises a right tray base 111, and a plurality of right tray side supporting blocks 112 are arranged on the outer side of the top surface of the right tray base 111 from front to back at intervals;
a right tab slot 9 is arranged at the upper part of the gap between any two right tray side supporting blocks 112;
the left lug groove 8 and the right lug groove 9 are arranged in bilateral symmetry. Therefore, the lithium ion power pouch battery 100 can be guaranteed to move in a direction perpendicular to the tray liner.
The left end and the right end of the lithium ion power soft package battery 100 to be transported are respectively vertically and transversely placed in the gap between the left tray lining 10 and the right tray lining 11.
The utility model discloses in, on the concrete realization, left tray inside lining 10 and right tray inside lining 11 are parallel to each other when the installation.
The utility model discloses in, on specifically realizing, utmost point ear groove 8 in the left side and utmost point ear groove 9 are narrow structure under wide. Therefore, in the falling and rising processes of the lithium ion power soft package battery 100, the lining does not scratch the sealing area 3, the left tab area 1 and the right tab area 4 of the lithium ion power soft package battery 100, and can play a shaping role for the left tab area 1 and the right tab area 4 of the lithium ion power soft package battery 100.
The utility model discloses in, on specifically realizing, left utmost point ear groove 8 and right utmost point ear groove 9 are preferred to be V style of calligraphy structure.
In the present invention, in the specific implementation, the lower part of the gap between any two left tray side support blocks 102 has a left clearance 71 (which is a gap);
the left clearance 71 is arranged corresponding to the fin part 2 on the left end of the lithium ion power soft package battery 100, and the shape and the size are correspondingly matched;
the left clearance 71 is positioned below the left tab slot 8 and communicated with the left tab slot 8;
a right clearance 72 (which is a gap) is formed at the lower part of the gap between any two right tray side supporting blocks 112;
the right clearance 72 is arranged corresponding to the edge folding area 5 on the right end of the lithium ion power soft package battery 100, and the shape and the size are correspondingly matched;
the right clearance 72 is located below the right tab slot 9 and is communicated with the right tab slot 9.
It should be noted that, to the utility model discloses, the tray inside lining is provided with many places and keeps away the sky (keep away empty 71, the right side including a left side and keep away empty 7), both can avoid laminate polymer battery's hem region 5, can avoid laminate polymer battery's fin part 2 again.
The utility model discloses in, specifically realize, the utility model discloses a tray inside lining does not have stress concentration point, simultaneously, contained angle R1 between the left side edge of left tray base 101 top surface and left tray side braced block 102 to and contained angle R2 between the right side edge of right tray base 111 top surface and right tray side braced block 112, can not be too big, prevent that inside lining and laminate polymer battery from interfering.
The utility model discloses in, on specifically realizing, the utility model discloses a tray inside lining can be dismantled, the installation fast, is fit for different money batteries.
It should be noted that, to the utility model discloses, when the design, the utmost point ear groove of tray inside lining is wide narrow structure down, and the battery is at the in-process that falls down, and utmost point ear groove can play the guide positioning effect to utmost point ear. Meanwhile, the thickness of the tray lining is utilized to fix the degree of freedom of the other direction of the tab. The tab of the lithium ion power soft package battery 100 is positioned and shaped by three degrees of freedom in directions of X, Y, Z constrained by the V-shaped structure of the tab groove, the bottom of the tray and the thickness of the lining of the tray.
The lithium ion power soft package battery is characterized in that the outer package of the lithium ion power soft package battery is an aluminum plastic film, the thickness of the lithium ion power soft package battery is very thin, and the lithium ion power soft package battery is very easy to scratch and pierce, so that the width of the lug groove is very strictly controlled. In the process of ascending and descending the battery, the tray lining can neither scratch the sealing area of the soft package battery nor scratch the lug area, and can also play the roles of positioning and shaping the lug of the soft package battery.
In order to prevent to destroy lithium ion power laminate polymer battery's appearance, the utility model discloses a tray inside lining is in many places design and is kept away the sky, include the corresponding position of the hem region with laminate polymer battery and laminate polymer battery's fin part. In order to avoid the gap flanging area, the lug grooves cannot be completely designed into a V-shaped symmetrical structure. In order to avoid the fish fin part, the joint of the bottom of the tray lining and the lug groove is hollowed.
For the present invention, the tray liner is an injection molded part, and the design of the R corners (e.g., R1 and R2 corners) is too small, which can cause stress concentrations that can cause early failure. The R angle is too big in design, and tray inside lining R angle department can interfere with laminate polymer battery appearance. Therefore, the R-angle control of the tray liner is very tight, causing neither stress concentration nor interference with the pouch cell.
It should be noted that, to the utility model discloses, lithium ion power laminate polymer battery 100's utmost point ear is pressed from both sides tightly in the tray inside lining to can prevent that battery circulation in-process utmost point ear from taking place crooked, reduce the OCV test and change into the secondary damage of station to battery utmost point ear.
In the utility model, the left tray lining and the right tray lining are required to be parallel, and the left lug groove and the right lug groove are symmetrically arranged, so as to ensure that the battery moves in the direction vertical to the tray lining; simultaneously, the left utmost point ear groove and the right utmost point ear groove all are wide structure down, can not fish tail the seal region of battery, can play the effect of plastic to the battery utmost point ear again.
To sum up, compare with prior art, the utility model provides a pair of lithium ion power laminate polymer battery's tray inside lining, its structural design science can guarantee that the battery is at the circulation in-process, and the utmost point ear of battery can not take place the bending to improve the production quality of final battery, have the significance of great production practice.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
