Equal distance, equal angle or equal area means that the tolerance range is -1% to 1%.

[0054] like Figures 1 to 11As shown, a tray of a preferred embodiment of the present invention has a first direction X, a second direction Z and a third direction Y which are perpendicular to each other, the tray is used to restrain a battery 1, the battery 1 includes a shell 11 and a cover 12 connected to one end of the shell 11; the tray includes a tray body 2 and a restraining body 10, the number of the restraining bodies 10 is multiple, the multiple restraining bodies 10 are connected to the tray body 2 along the first direction X, and two adjacent restraining bodies 10 are detachably connected; wherein, in the first direction X, a accommodating cavity 100 is formed between two adjacent restraining bodies 10, the accommodating cavity 100 is used to accommodate the battery 1, the accommodating cavity 100 has a first cavity wall 101 and a second cavity wall 102, the first cavity wall 101 and the second cavity wall 102 are arranged along the second direction Z, along the second direction Z, the second cavity wall 102 is connected to the first cavity wall 101 close to the cover 12 side, the first cavity wall 101 is used to abut the shell 11; along the first direction X, there is a first gap 100A between the second cavity wall 102 and the shell 11.

[0055] Specifically, when the tray constrains the battery 1, the battery 1 is placed in the accommodating cavity 100, and the first cavity wall 101 abuts against the shell 11 to limit the expansion of the battery 1, and a first gap 100A is provided between the second cavity wall 102 and the shell 11. Since the second cavity wall 102 is connected to the side of the first cavity wall 101 close to the cover 12, when the first cavity wall 101 abuts against the shell 11, based on the existence of the first gap 100A, the second cavity wall 102 will not abut against the connection between the shell 11 and the cover 12, and the connection between the shell 11 and the cover 12 is not easy to crack, thereby preventing the battery 1 from being damaged.

[0056] In actual application, before the tray restrains the battery 1, there is a distance between two adjacent restraining bodies 10 in the first direction X, and the two adjacent restraining bodies 10 are in a separated state so that the battery 1 to be restrained can be placed between the two restraining bodies 10; and after the battery 1 is restrained, the two adjacent restraining bodies 10 are converted from a connected state to a separated state so that the battery 1 can be taken out of the accommodating cavity 100. This is the prior art and the present application will not elaborate on it.

[0057] Further, such as Figure 3 As shown, the accommodating cavity 100 also has a third cavity wall 103, and the third cavity wall 103 is connected between the first cavity wall 101 and the second cavity wall 102. The first cavity wall 101 and the second cavity wall 102 are smoothly transitioned through the third cavity wall 103. Therefore, when the first cavity wall 101 abuts against the shell 11, it is possible to avoid causing indentations to the shell 11, thereby ensuring the production quality of the battery 1.

[0058] In this embodiment, if Figure 4As shown, the battery 1 is a cylindrical battery 1. In this case, the cavity surface of the accommodating cavity 100 is cylindrical; wherein the shell 11 includes a peripheral side wall 111 and a bottom wall 112, one end of the peripheral side wall 111 is connected to the cover body 12, and the other end is connected to the bottom wall 112, and the connection between the peripheral side wall 111 and the bottom wall 112 is a corner. Therefore, when the tray constrains the battery 1, the connection between the peripheral side wall 111 and the bottom wall 112 is also prone to cracking. Based on this, as a preferred embodiment of this embodiment, Figure 3 and Fig.10 As shown, the accommodating cavity 100 further comprises a fourth cavity wall 104 and a fifth cavity wall 105, wherein the fourth cavity wall 104, the first cavity wall 101 and the second cavity wall 102 are arranged along the second direction Z, wherein the fourth cavity wall 104 is connected to a side of the first cavity wall 101 away from the second cavity wall 102 along the second direction Z, and the fourth cavity wall 104 and the fifth cavity wall 105 intersect, and along the first direction X, a second gap 100B is provided between the fourth cavity wall 104 and the peripheral side wall 111; in practical applications, when the tray restrains the battery 1, the bottom wall 112 of the battery 1 is connected to the bottom wall 112 of the battery 1. Connected to the fifth cavity wall 105, the first cavity wall 101 abuts against the peripheral side surface of the battery 1, and there is a second gap 100B between the fourth cavity wall 104 and the peripheral side wall 111. Since the fourth cavity wall 104 is connected to the side of the first cavity wall 101 away from the second cavity wall 102, when the first cavity wall 101 abuts against the peripheral side surface, based on the existence of the first gap 100A, the fourth cavity wall 104 will not abut against the connection between the peripheral side wall 111 and the bottom wall 112, and the connection between the peripheral side wall 111 and the bottom wall 112 is not easy to crack, which can prevent the battery 1 from being damaged.

[0059] It should be noted that before the tray restrains the battery 1 , the battery 1 is placed on the wall surfaces of the two adjacent restraining bodies 10 constituting the fifth cavity wall surface 105 to ensure that the restraint process of the battery 1 proceeds normally.

[0060] Further, such as Figure 3 As shown, the accommodating cavity 100 also has a sixth cavity wall 106, and the sixth cavity wall 106 is connected between the first cavity wall 101 and the fourth cavity wall 104. The first cavity wall 101 and the fourth cavity wall 104 are smoothly transitioned through the sixth cavity wall 106. Therefore, when the first cavity wall 101 abuts against the shell 11, it is possible to avoid causing indentations to the shell 11, thereby ensuring the production quality of the battery 1.

[0061] In this embodiment, if Figures 5 to 7As shown, one of the two adjacent restraining bodies 10 is a first restraining member 3, and the other restraining body 10 is a second restraining member 4; wherein, the tray also includes a first guide claw 5; the first guide claw 5 is connected to a side of the first restraining member 3 facing the second restraining member 4, and the first guide claw 5 is provided on both sides of the accommodating cavity 100 in the third direction Y; and the second restraining member 4 has a first accommodating groove 401, the first accommodating groove 401 is located on the side of the second restraining member 4 facing the first restraining member 3, and the first accommodating groove 401 is provided on both sides of the accommodating cavity 100 in the third direction Y, and the first guide claw 5 is inserted into the first accommodating groove 401. Based on this, in actual application, the first guide claw 5 cooperates with the first accommodating groove 401 to play a guiding role. In the process of the first restraining member 3 and the second restraining member 4 being converted from a separated state to a connected state to restrain the battery 1, the first guide claw 5 is gradually inserted into the first accommodating groove 401. The first guide claw 5 can provide stable guidance to ensure that the first restraining member 3 and the second restraining member 4 are smoothly connected.

[0062] In practical applications, the plane where the axis of the accommodating cavity 100 is located is referred to as the first plane, and the first plane is perpendicular to the third direction Y. Fig.12 As shown, when the battery 1 is placed between the first restraint member 3 and the second restraint member 4, the axis of the battery 1 must coincide with the first plane to enable the restraint process to proceed smoothly. However, due to the existence of operational errors, the axis of the battery 1 will inevitably deviate from the first plane. Therefore, as a preferred embodiment of this embodiment, Figure 6 As shown, the first guide claw 5 has a first guide arc surface 51, the first guide arc surface 51 faces the accommodating cavity 100, and along the arc extension direction of the first guide arc surface 51, the first guide arc surface 51 has a first end 511 and a second end 512 that are oppositely arranged, the first end 511 is directly connected to the first cavity wall 101, and in the third direction Y, the second end 512 is located on the side of the first end 511 away from the accommodating cavity 100. Based on this, the battery 1 is restrained by the two restraining bodies 10 as shown in FIG. Figure 12 to Figure 14 As shown, when the battery 1 is placed between the first restraint 3 and the second restraint 4, if the axis of the battery 1 deviates from the first plane, then when the first restraint 3 and the second restraint 4 approach each other in the first direction X, based on the setting of the first guide arc surface 51, the first guide claw 5 will move the battery 1 toward the side where the first plane is located after contacting the battery 1, so that the axis of the battery 1 coincides with the first plane, which is beneficial to the normal restraint work of the battery 1, and because the first cavity wall 101 is directly connected to the first end 511 of the first guide arc surface 51, the first restraint 3 and the second restraint 4 will not cause direct indentations on the shell 11 when they approach each other, thereby ensuring the production quality of the battery 1.

[0063] As a preferred embodiment of this embodiment, Figures 5 to 7As shown, the tray also includes a second guide claw 6; the second guide claw 6 is connected to a side of the second restraining member 4 facing the first restraining member 3, and the second guide claw 6 is provided on both sides of the accommodating cavity 100 in the third direction Y; wherein the first restraining member 3 has a second accommodating groove 301, the second accommodating groove 301 is located on a side of the first restraining member 3 facing the second restraining member 4, and the accommodating cavity 100 is provided with a second accommodating groove 301 on both sides in the third direction Y, and the second guide claw 6 is inserted in the second accommodating groove 301; in the second direction Z, the first guide claw 5 and the second accommodating groove 301 are arranged at intervals, and the second The guide claw 6 and the first receiving groove 401 are arranged at intervals. In actual application, the second guide claw 6 cooperates with the second receiving groove 301 to play a guiding role. In the process of the first restraint 3 and the second restraint 4 being converted from a separated state to a connected state to restrain the battery 1, the first guide claw 5 is gradually inserted into the first receiving groove 401, and the second guide claw 6 is gradually inserted into the second receiving groove 301. The first guide claw 5 and the second guide claw 6 can provide stable guidance, so that the first restraint 3 and the second restraint 4 can be connected more smoothly. The operation is simple and convenient, the structure is relatively simple, and the manufacturability is strong.

[0064] Further, such as Figure 7 As shown, the second guide claw 6 has a second guide arc surface 61, the second guide arc surface 61 faces the accommodating cavity 100, and along the arc extension direction of the second guide arc surface 61, the second guide arc surface 61 has a third end 611 and a fourth end 612 that are relatively arranged, and the third end 611 is directly connected to the first cavity wall 101. In the third direction Y, the fourth end 612 is located on the side of the third end 611 away from the accommodating cavity 100. Similarly, the process of the battery 1 being restrained by the two restraining bodies 10 is as shown in FIG. Figure 12 to Figure 14 As shown, when the battery 1 is placed between the first restraint member 3 and the second restraint member 4, if the axis of the battery 1 deviates from the first plane, then when the first restraint member 3 and the second restraint member 4 approach each other in the first direction X, based on the setting of the first guide arc surface 51 and the second guide arc surface 61, the first guide claw 5 and the second guide claw 6 will move the battery 1 toward the side where the first plane is located after contacting the battery 1, so that the axis of the battery 1 coincides with the first plane, which is beneficial to the normal restraint work of the battery 1, and because the first cavity wall 101 is directly connected to the third end 611 of the second guide arc surface 61, the first restraint member 3 and the second restraint member 4 will not cause direct indentations on the shell 11 when they approach each other, further ensuring the production quality of the battery 1.

[0065] In this application, if Figure 8As shown, in the second direction Z, the edge of the second cavity wall 102 at one end away from the first cavity wall 101 forms a first opening 200, and the first opening 200 is connected to the accommodating cavity 100. The arrangement of the first opening 200 facilitates the placement of the battery 1 between two adjacent restraining bodies 10, and is also beneficial for the battery 1 with the positive and negative electrodes arranged at the same end (the positive and negative electrodes are located at the same end of the battery 1 along its length direction) to perform formation and capacity separation processes after being restrained.

[0066] like Figure 8 As shown, the accommodating cavity 100 has a second opening 300, and the second opening 300 is located on the fifth cavity wall 105. At this time, the tray can restrain the battery 1 with different positive and negative ends (the positive and negative electrodes are respectively located at the two ends of the battery 1 along its length direction) to enable the battery 1 to undergo processes such as formation and capacity separation.

[0067] In this embodiment, if Figure 1 , Figure 5 and Fig.11 As shown, the restraint body 10 includes a main body 10A and a clamping part 10B. In the first direction X, a accommodating cavity 100 is formed between two adjacent main body parts 10A. In the third direction Y, both ends of the main body 10A are connected with the clamping parts 10B; the tray body 2 includes a connecting seat 21 and a clamping block 22. The connecting seat 21 has a restraint groove 2101. There are multiple clamping blocks 22. Multiple clamping blocks 22 and multiple restraint bodies 10 are all arranged in the restraint groove 2101. Each restraint body 10 is provided with clamping blocks 22 on both sides in the third direction Y. In the first direction X, two adjacent clamping blocks 22 abut against each other; wherein, the clamping block 22 is provided with a clamping groove 2201 on a side facing the main body 10A, the clamping part 10B is inserted in the clamping groove 2201, and the clamping part 10B is away from the third direction Y. The end face of the main body 10A abuts against the groove wall of the snap-in groove 2201; specifically, a plurality of snap-in blocks 22 and a plurality of restraining bodies 10 form a restraining assembly, and the tray also includes a pressure-applying assembly, the function of the pressure-applying assembly is to apply force to the restraining assembly to achieve the restraint of the battery 1, wherein the pressure-applying assembly can be an assembly with a power source such as a cylinder, a hydraulic cylinder, or an assembly with a bolt as a force-applying member, which is the prior art and the present application does not impose any restrictions on this; in actual application, the pressure-applying assembly mainly applies force to the snap-in block 22 to make the two adjacent restraining bodies 10 approach each other and abut against each other to restrain the battery 1, at this time, the snap-in portion 10B is the main force-bearing position of the restraining body 10, and the force on the main body 10A is relatively small, thereby, when the battery 1 is restrained by two adjacent main bodies 10A, it can avoid being damaged by excessive force on the battery 1.

[0068] In practical applications, due to the existence of processing errors, the lengths of the multiple batteries 1 in the first direction X may be different to a certain extent. In order to avoid the battery 1 from being crushed and exploded by the restraining body 10, further, as Fig.11As shown, in the first direction X, both ends of the clamping block 22 are connected to a limit block 221, and in two adjacent clamping blocks 22, two adjacent limit blocks 221 abut against each other. Based on this, the limit blocks 221 ensure the minimum size of the battery 1 after being compressed in the first direction X, which can avoid the battery 1 from being crushed.

[0069] In this embodiment, if Figure 1 As shown, the connecting seat 21 includes a supporting plate 211, a limiting plate 212 and a limiting column 213. In the first direction X, both ends of the supporting plate 211 are connected to the limiting plates 212. The limiting plates 212 at both ends of the supporting plate 211 are connected through the limiting columns 213. The length direction of the limiting columns 213 is the same as the first direction X, that is, the limiting columns 213 extend along the first direction X, and both ends of the limiting plates 212 in the third direction Y are connected to the limiting columns 213. A restraint groove 2101 is formed between the supporting plate 211, the limiting plate 212 and the limiting column 213. The connecting seat 21 of this structure is simple in structure and easy to assemble.

[0070] Further, such as Fig.11 As shown, a limiting groove 2202 is provided on a side of the clamping block 22 facing away from the main body 10A. The limiting groove 2202 penetrates the clamping block 22 along the first direction X. Figure 1 As shown, the limiting column 213 is provided with a limiting groove 2202, thereby enabling the clamping block 22 to be stably set in the restraining groove 2101, and the limiting column 213 can play a role in guiding the clamping block 22 to move smoothly along the first direction X; in addition, the limiting groove 2202 of this structure has an open side on the side away from the restraining body 10 in the third direction Y. When the clamping block 22 is assembled to the connecting seat 21, the clamping block 22 is placed in the restraining groove 2101, and then the limiting column 213 is inserted into the limiting groove 2202 from the open side of the limiting groove 2202. The installation is convenient, and the clamping block 22 is easy to disassemble when the pallet needs maintenance after long-term use.

[0071] In this embodiment, if Figure 1 and Figure 2 As shown, both the main body 10A and the clamping portion 10B have heat dissipation holes 400 that are arranged through the second direction Z. The heat dissipation holes 400 are arranged at intervals from the accommodating cavity 100. The function of the heat dissipation holes 400 is to provide air circulation. When the battery 1 is restrained by the tray and undergoes formation and capacity separation processes during the charging and discharging process, the temperature difference between the two ends of the tray in the second direction Z can be reduced.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
