[0031] In the related art, for a battery with a relatively light mass, the ventilation hole cannot completely avoid the generation of negative pressure. When the blister tray is disassembled, the battery will still be displaced. When the battery is displaced, the battery is easily damaged due to the chaotic position. In view of the above problems, the embodiments of the present application provide a battery packaging tray and assembly, which can reduce the contact area between the battery in the upper tray body and the lower tray body, and thus can effectively avoid the displacement of the battery in the placement groove due to negative pressure factors.

[0032] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0033] Please refer to Figures 1 - 4 , the present application provides a battery packaging tray, which includes a tray body 100. The tray body 100 is provided with a plurality of placement grooves 101 for placing batteries. The openings of the placement grooves 101 face upward of the tray body 100; a boss 112 extending in a direction away from the opening of the placement groove 101 is provided at the bottom of the placement groove 101; the boss 112 is used to correspond to the placement groove 101 of another superimposed battery packaging tray and contact the battery 200 in the placement groove 101.

[0034] The battery packaging tray of this embodiment can be a blister tray. A blister tray is a plastic product formed by heating a plastic sheet until it becomes soft through the blister process, then vacuum - adsorbing it onto the surface of a mold and cooling it. When storing blister trays, multiple blister trays are usually stacked, and adjacent blister trays are in contact with each other. A number of placement grooves 101 and / or bosses 112 of the tray body 100 are formed by the blister process to cause the tray body 100 to be recessed in the thickness direction of the tray body 100. The battery 200 can be a button battery, and the battery 200 is accommodated in the placement groove 101, and the placement groove 101 plays a role in protecting the battery 200.

[0035] See Figure 1 and Figure 4 , in the solution provided by this application, the boss 112 at the bottom of the tray body 100a corresponds to the placement groove 101 of another stacked tray body 100b below. The placement groove 101 includes a bottom wall 111 located away from the opening of the placement groove 101 and an opening located in the upper part of the tray body 100. The boss 112 can be provided on the side of the bottom wall 111 of each placement groove 101 facing away from the opening.

[0036] The lower end of the boss 112 contacts the upper surface of the battery in the placement groove 101 of the lower - layer tray body 100. Compared with the related art, it can reduce the contact area between the batteries in the upper - layer tray body 100a and the lower - layer tray body 100b, and at the same time increase the ventilation space of the placement groove 101 of the lower - layer tray body 100b. Furthermore, it can effectively avoid generating negative pressure in the tray when disassembling the tray, prevent the batteries in the tray from shifting due to negative pressure, and then ensure the stability of the battery position, avoiding damage due to chaotic battery positions.

[0037] See Figure 1 , in this embodiment, a number of placement grooves 101 are arranged in an array on the tray body 100. The tray body 100 is rectangular, and a number of placement grooves 101 can be arranged in a rectangular array on the tray body 100. A boss 112 is provided in the direction away from the opening of each placement groove 101. When two tray bodies 100 overlap, a number of bosses 112 of one tray body 100 correspond one - to - one with a number of placement grooves 101 of the other tray body 100, so that multiple bosses 112 of the upper - layer tray body 100 can respectively contact each battery in the lower - layer tray body 100, avoiding the displacement of the batteries in the lower - layer tray body 100, and then ensuring the reliability of battery packaging.

[0038] Continue to see Figure 3 and Figure 4, in some embodiments, the boss 112 has a preset extension height, and the cross-sectional area of the boss 112 can be smaller than that of the placement groove 101. When the two tray bodies 100 overlap, the boss 112 of one tray body 100a extends into the opening of the placement groove 101 of the other tray body 100b. The extension height of the boss 112 can be set according to the thickness of the battery. When the thickness of the battery is small, the extension height of the boss 112 can be increased. When the thickness of the battery is large, the extension height of the boss 112 can be decreased, so that the boss 112 can contact the upper surface of the battery. The boss 112 can be arranged corresponding to the center of the bottom of the placement groove 101. In this way, the boss 112 of the upper-layer battery packaging tray contacts the center of the upper surface of the battery of the lower-layer battery packaging tray, making the battery more stable in the placement groove 101.

[0039] In this embodiment, the boss 112 is set as a column shape. The diameter of the boss 112 can be 2 - 4 mm, and the extension height of the boss 112 can be 2 - 4 mm. It should be noted that the above dimensions are only exemplary. In other embodiments, the parameters of the boss 112 can also be freely set according to the actual situation.

[0040] In some embodiments, the end of the boss 112 is provided with a contact surface that contacts the battery. The contact surface can be a plane. The boss 112 and the battery are in surface contact, which can avoid stress concentration and pressing damage to the battery. The edge of the contact surface is provided with a rounded corner or a chamfer. The rounded corner or the chamfer can avoid scratching the surface of the battery.

[0041] See Figure 2 , in some embodiments, a limiting structure 113 is provided on one side of the placement groove 101. The limiting structure 113 can be a limiting block provided around the placement groove 101. When the battery is placed in the groove body, the periphery of the battery is limited by the limiting blocks. Specifically, 4 limiting blocks can be provided, which are respectively located around the placement groove, so that the battery is limited by 4 limiting blocks in the horizontal direction, and at the same time, the battery is limited by the boss 112 of the upper-layer stacked battery packaging tray in the vertical direction. In this way, the battery in the placement groove 101 is fixed in both the horizontal direction and the vertical direction, which can further improve the stability of the battery position. In some embodiments, a groove is also provided on one side of the placement groove 101, and the pins of the battery are received in the groove. The groove can protect the pins and avoid damage to the pins, and can also improve the consistency of the battery placement direction.

[0042] See Figure 1 In some embodiments, the tray body 100 is provided with ventilation holes 103. The ventilation holes 103 are arranged in the area outside the placement groove 101. For example, they can be arranged in the middle of several placement grooves 101. When the trays are disassembled, the ventilation holes 103 communicate the inside and outside of the trays, avoiding the occurrence of negative pressure inside the trays.

[0043] In some embodiments, the tray body 100 is provided with a support portion 102, and the support portion 102 is used to support another stacked battery packaging tray, so that the pressure generated on the battery when the boss 112 contacts the battery can be reduced, and the battery can be prevented from being damaged. In some embodiments, the support platform is arranged at the middle part and / or the edge position of the tray body 100.

[0044] In some embodiments, the tray body 100 is provided with an edge portion and a middle portion. The middle portion is connected to two opposite sides of the tray. The edge portion and the middle portion are not provided with the placement groove 101. The support portion 102 can be arranged on the edge portion and the middle portion. Specifically, the support portion 102 can be a concave platform formed by recessing a certain distance downward at the edge portion and the middle portion. A plurality of placement grooves 101 are arranged on both sides of the middle portion. The thickness (distance from the bottom to the top) of the edge portion and the middle portion is greater than the area where the placement groove 101 is provided. After such an arrangement, when a plurality of tray bodies 100 are stacked, the adjacent tray bodies 100 are limited in the stacking direction by the support portion 102, which can not only improve the bonding stability after the plurality of tray bodies 100 are stacked, but also, when a downward external force is applied to the tray, the external force is absorbed by the support portion 102 of the tray and will not be transmitted to the battery by the boss 112, thereby protecting the battery from being damaged.

[0045] The present application provides a battery packaging tray assembly, including a plurality of battery packaging trays according to any one of the above embodiments, and the plurality of battery packaging trays are overlapped; the boss of one battery packaging tray is used to contact the battery in an adjacent another battery packaging tray.

[0046] In the solution provided by the present application, since the boss 112 in the direction away from the opening of the placement groove 101 corresponds to the placement groove 101 of another stacked battery packaging tray below, the end of the boss 112 contacts the upper surface of the battery in the placement groove 101. Compared with the related art, the contact area between the upper tray and the battery in the lower tray can be reduced, the negative pressure in the tray can be reduced, and further the stability of the battery position can be ensured, and the battery can be prevented from being damaged due to the disorder of the battery position.

[0047] The above has described the embodiments of the present application. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
