[0015] Optionally, the third limiting device includes a fourth limiting member, a fifth limiting member, and a driving mechanism.

[0051] As an indispensable part of the battery production process, the electrolyte filling and co-assembly process affects the quality, performance and production efficiency of the battery.

[0052] To improve the production efficiency and quality of battery electrolyte filling, this application provides a battery tray for positioning and clamping batteries during the battery electrolyte filling process, facilitating the completion of the electrolyte filling operation.

[0053] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a battery tray 100 provided in an embodiment of this application. The battery tray 100 includes a support base 2, an injection connector 3, and a limiting device 1. Both the injection connector 3 and the limiting device 1 are connected to the support base 2. The injection connector 3 is used to connect an injection device to inject liquid into the battery 200. The limiting device 1 is used to limit the position of the battery 200 on the support base 2. The size of the limiting space of the limiting device 1 for the battery 200 is adjustable to accommodate batteries 200 of different sizes and to match the position of the battery 200 at the injection connector 3.

[0054] The support base 2 serves as the basic load-bearing component of the battery tray 100, providing a fixed connection point for the liquid injection connector 3 and the limiting device 1. Since the limiting device 1 can adjust the size of the limiting space of the battery 200, various batteries 200 of different sizes can be used in the liquid injection process and subsequent processing using the battery tray 100. The limiting device 1 can improve the versatility of the battery tray 100.

[0055] An injection connector 3 is provided on the support base 2. Through the injection connector 3, the injection device and the battery 200 can be connected to avoid leakage caused by poor connection between the injection device and the battery 200.

[0056] Thus, the battery tray 100 provided in this application embodiment, through the adjustable setting of the liquid injection device and the limiting device 1, can achieve good positioning and docking of batteries 200 of different sizes without replacing the tray when performing liquid injection operations, thereby reducing production costs and improving production efficiency.

[0057] Please refer to Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the structure of a liquid injection connector 3 provided in an embodiment of this application. In some embodiments of this application, the liquid injection connector 3 is configured as a normally closed liquid injection connector 3.

[0058] By setting the injection connector 3 as a normally closed type, when the injection device is connected to the injection connector 3, the injection device can open the injection connector 3 to perform the injection operation on the battery 200. When the injection device completes the injection of the battery 200 and leaves the injection connector 3, the injection connector 3 returns to the normally closed state, thereby sealing the battery 200. In this way, the injection connector 3 can both complete the injection operation on the battery 200 and maintain the pressure of the battery 200, preventing leakage of the battery 200 after the injection is completed.

[0059] Specifically, in some embodiments, the electrolyte injection connector 3 may include an injection element 31 and a pressure-holding plug 32. The injection element 31 is fixedly connected to the support base 2 and can position the battery 200 between itself and the injection device. The pressure-holding plug 32 is connected to the injection element 31 and is equipped with a valve. When the battery 200 is injected with electrolyte, the valve opens, allowing the electrolyte to smoothly pass through the injection element 31 into the battery 200 cavity. When the battery 200 is injected with electrolyte and the injection device leaves the electrolyte injection connector 3, the valve closes. This seals the battery 200 and prevents the electrolyte from flowing out.

[0060] In some embodiments, the liquid injection connector 3 may further include a seal 33 connected between the liquid injection component 31 and the battery 200. The seal 33 is used to ensure a seal between the liquid injection component 31 and the battery 200, preventing the battery 200 from leaking air or liquid through the connection gap between the liquid injection component 31 and the battery 200.

[0061] In some embodiments, the seal 33 may be made of rubber, plastic or sealant, etc., to achieve a good seal between the liquid injection component 31 and the battery 200.

[0062] Please continue to refer to Figure 1 In some embodiments, the limiting device 1 may include a first limiting device 11, a second limiting device 12 and a third limiting device 13, wherein the first limiting device 11 is used to limit the battery 200 along the thickness direction F1 of the battery 200, and the thickness of the limiting space of the first limiting device 11 for the battery 200 is adjustable to adapt to batteries 200 of different thicknesses.

[0063] With an adjustable thickness limiting space, it can be compatible with batteries 200 of different thicknesses, eliminating the need to design a dedicated limiting structure for each type of battery 200, reducing the customization cost of the battery tray 100. Furthermore, the first limiting device 11 with adjustable thickness direction F1 space can prevent the battery 200 from moving or shifting along the thickness direction F1, facilitating good docking between the battery 200 and the liquid injection connector 3, and achieving precise liquid injection.

[0064] The second limiting device 12 is used to limit the battery 200 along the width direction F2 of the battery 200, and can adjust the position of the battery 200 in the width direction F2 of the battery 200 so that the position of the battery 200 matches that of the liquid injection connection structure.

[0065] The second limiting device 12 can realize the position calibration of the battery 200 in the width direction F2. According to the size of the battery 200 in the width direction F2, the second limiting device 12 can adjust the position of the battery 200 in the width direction F2 so that the liquid injection port of the battery 200 can be precisely aligned with the liquid injection connector 3, thereby achieving precise liquid injection.

[0066] The third limiting device 13 is used to limit the battery 200 along the length direction F3 of the battery 200, and the length of the limiting space of the third limiting device 13 on the battery 200 is adjustable to adapt to batteries 200 of different lengths.

[0067] The adjustable length limiting space allows for compatibility with batteries 200 of different lengths, eliminating the need to design dedicated limiting structures for each battery 200 length and reducing the customization cost of the battery tray 100. The third limiting device 13, with its adjustable length-direction F3 limiting space, prevents the battery 200 from shifting or moving along the length direction F3, further enhancing the stability of the liquid injection process.

[0068] Through the coordinated operation of the first limiting device 11, the second limiting device 12 and the third limiting device 13, the battery tray 100 can limit the battery 200 along the thickness direction F1, the width direction F2 and the length direction F3, reduce the displacement of the battery 200 caused by vibration or pressure changes during the liquid injection process, and ensure the stability of the liquid injection of the battery 200.

[0069] Please refer to Figure 1 and Figure 3 , Figure 3 This is a schematic diagram of the structure of a first limiting device 11 provided in an embodiment of this application. In some embodiments, the first limiting device 11 includes a first limiting member 111 and a second limiting member 112. The first limiting member 111 and the second limiting member 112 are arranged along the length direction F3 of the limiting space, and at least one of the first limiting member 111 and the second limiting member 112 is movable along the thickness direction F1 of the limiting space.

[0070] The first limiting member 111 includes at least one first positioning post 1111, and the second limiting member 112 includes at least one second positioning post 1121. At least one first positioning post 1111 and at least one second positioning post 1121 correspond to each other. The battery 200 can be accommodated between the second positioning post 1121 and the corresponding first positioning post 1111, and the battery 200 is positioned along the thickness direction F1 of the battery 200.

[0071] When at least one of the first limiting member 111 and the second limiting member 112 moves along the thickness direction F1 of the limiting space, the space between the second positioning post 1121 and the corresponding first positioning post 1111 can change. Therefore, when batteries 200 of different thicknesses are installed on the battery tray 100, the size of the space between the first positioning post 1111 and the second positioning post 1121 can be changed by adjusting the positions of the first limiting member 111 and the second limiting member 112 along the thickness direction F1 of the limiting space, thereby adapting to batteries 200 of different thicknesses. In this way, the versatility of the battery tray 100 can be improved.

[0072] Since a limiting space in the thickness direction F1 of the battery 200 can be formed between a first positioning post 1111 and a second positioning post 1121, the battery 200 can be positioned in the thickness direction F1. If it is desired to perform positioning processing on multiple batteries 200 simultaneously, multiple first positioning posts 1111 and multiple second positioning posts 1121 can be respectively provided on the first limiting member 111 and the second limiting member 112.

[0073] In some embodiments, the number of first positioning posts 1111 and second positioning posts 1121 can both be set to multiple. Multiple first positioning posts 1111 are arranged at intervals along the thickness direction F1 of the limiting space, and multiple second positioning posts 1121 are also arranged at intervals along the thickness direction F1 of the limiting space. Multiple second positioning posts 1121 correspond to multiple first positioning posts 1111, and a limiting space is formed between each second positioning post 1121 and the corresponding first positioning post 1111.

[0074] By moving one of the first limiting member 111 and the second limiting member 112 along the thickness direction F1 of the limiting space, the space between each second positioning post 1121 and the corresponding first positioning post 1111 can be adjusted synchronously. In this way, multiple batteries 200 can be limited in the thickness direction F1 at the same time, which facilitates the synchronous liquid injection processing of multiple batteries 200.

[0075] In addition, when two sets of batteries 200 of different sizes are replaced, the size of multiple thickness direction F1 limiting spaces can be adjusted by adjusting the first limiting member 111 and / or the second limiting member 112, without having to make repeated adjustments, thereby reducing the error of the thickness direction F1 of the limiting space and reducing the adjustment steps, which facilitates the improvement of production efficiency.

[0076] In some embodiments, the first limiting device 11 further includes a first guide rail structure, which includes a first slide rail extending along the thickness direction F1 of the battery 200 and a first slider cooperating with the first slide rail. The first slide rail is fixedly connected to the support base 2, and the first slider is fixedly connected to the first limiting member 111 and / or the second limiting member 112. Since the first slider cooperates with the first slide rail and the first slider can slide along the thickness direction F1 of the battery 200, the first limiting member 111 or the second limiting member 112 can slide along the thickness direction F1 of the battery 200.

[0077] In this way, the first guide rail mechanism 113 can ensure the movement direction of the first limiting member 111 and the second limiting member 112, thereby realizing the adjustment of the limiting space along the thickness direction F1 by the first limiting device 11, and avoiding the limiting deviation caused by the movement direction deviation.

[0078] In some embodiments, the first guide rail mechanism 113 can be configured as two sets, one set of the first guide rail mechanism 113 is connected to the first limiting member 111 and the support base 2, and the other set of the first guide rail mechanism 113 is connected to the second limiting member 112 and the support base 2. In this way, when both the first limiting member 111 and the second limiting member 112 need to move relative to the support base 2 along the thickness direction F1 of the limiting space, the two sets of the first guide rail mechanism 113 provide guidance for the first limiting member 111 and the second limiting member 112 respectively, so that the movement of the first limiting member 111 and the second limiting member 112 will not be deviated, thereby making the limiting space between the first positioning post 1111 and the second positioning post 1121 more accurate, which is convenient for precise positioning of the battery 200.

[0079] In some embodiments, each group of first guide rail mechanisms 113 may also be configured as multiple, and the multiple first guide rail mechanisms 113 can be arranged along the thickness direction F1 of the limiting space. In this way, the multiple first guide rail mechanisms 113 can guide the first limiting member 111 or the second limiting member 112 in the thickness direction F1, thereby further improving the accuracy of the first limiting device 11 in guiding the battery 200 in the thickness direction F1.

[0080] In some embodiments, the first limiting device 11 may further include a gear and rack mechanism 114, which includes a first linear rack and a first gear. The first gear is connected to one of the first limiting member 111 and the second limiting member 112, and the first linear rack is connected to the other of the first limiting member 111 and the second limiting member 112. Because the first gear and the first linear rack mesh, when the first limiting member 111 moves, the gear and rack mechanism 114 can drive the second limiting member 112 to move in the opposite direction. This ensures the alignment of the first limiting member 111 and the second limiting member 112, thereby reducing the range of motion of the first limiting device 11 and minimizing the space occupied by the first limiting device 11 and the second limiting device 12.

[0081] In some embodiments of this application, the first limiting device 11 includes a first elastic member 115, which is connected between the first limiting member 111 and the second limiting member 112. When at least one of the first limiting member 111 and the second limiting member 112 moves along the thickness direction F1 of the limiting space, the first elastic member 115 is used to apply an elastic force to the first limiting member 111 and the second limiting member 112, so that the second positioning post 1121 and the corresponding first positioning post 1111 clamp the battery 200 along the thickness direction of the battery 200.

[0082] When the first limiting member 111 and the second limiting member 112 move in opposite directions along the thickness direction F1, the first elastic member 115 can store elastic potential energy by stretching or compressing. When the battery 200 is placed between the second positioning post 1121 and the corresponding first positioning post 1111, the first elastic member 115 can apply a force opposite to the direction of movement to the first limiting member 111 and the first limiting member 111, thereby applying a clamping force to the battery 200.

[0083] In this way, the battery tray 100 can fix the battery 200 in the thickness direction F1, reduce the displacement of the battery 200 caused by factors such as vibration, and thus ensure the accuracy and stability of the liquid injection of the battery 200.

[0084] In some embodiments of this application, the first elastic member 115 includes a mounting block 1151, a first spring 1152, and a second spring. The mounting block 1151 is connected to one end of the first limiting member 111 and the second limiting member 112 along the thickness direction F1 of the battery 200. The first spring 1152 is connected between the first limiting member 111 and the mounting block 1151, and the second spring is connected between the second limiting member 112 and the mounting block 1151. Thus, when the first limiting member 111 and the second limiting member 112 move towards both ends along the thickness direction F1 of the battery 200, one of the first spring 1152 and the second spring is compressed, and the other of the first spring 1152 and the second spring is stretched, thereby storing potential energy.

[0085] The axes of the first spring 1152 and the second spring are both in the same direction as the thickness F1 of the battery 200.

[0086] In some embodiments, the mounting block 1151 can be fixedly connected to the support base 2 to achieve the connection and fixation between the first limiting device 11 and the support base 2.

[0087] In some embodiments, the first elastic member 115 may also be connected to the other end of the first limiting member 111 and the second limiting member 112 along the thickness direction F1 of the battery 200. The first elastic member 115 is capable of storing elastic potential energy and clamping the battery 200 after it is placed.

[0088] Please refer to Figure 1 and Figure 4 , Figure 4 This is a schematic diagram of the structure of a second limiting device 12 provided in an embodiment of this application. In some embodiments, the second limiting device 12 includes a third limiting member 121. The limiting space has an opening on one side along the width direction F2 of the battery 200. The opening can be used to install and remove the battery 200, thereby improving the ease of operation of the battery tray 100.

[0089] It should be noted that the width direction F2 of the battery 200 is the same as the height direction of the battery tray 100 during use.

[0090] The third limiting member 121 is located on the other side of the limiting space along the width direction F2 of the battery 200. The third limiting member 121 can be used to support the battery 200 so that the battery 200 can be at a suitable height, which facilitates the docking of the battery 200 with the liquid injection connector 3, thereby enabling precise liquid injection into the battery 200.

[0091] The second limiting device 12 also includes a lifting drive mechanism 122, which is connected to the third limiting member 121 and is used to drive the third limiting member 121 to move along the width direction F2 of the battery 200 to adjust the position of the battery 200 in the width direction F2 of the battery 200.

[0092] The lifting drive mechanism 122 enables the third limiting member 121 to move along the width direction F2 of the battery 200. In this way, when the battery tray 100 is performing liquid injection on batteries 200 of different widths, the position of the battery 200 in the width direction F2 can be adjusted by adjusting the third limiting member 121, so that the liquid injection port on the battery 200 is connected with the liquid injection connector 3, thereby improving the accuracy and stability of liquid injection.

[0093] Please refer to Figure 1 , Figure 4 and Figure 5 , Figure 5 for Figure 4 The enlarged view of the second limiting device 12 shown shows that in some embodiments, the lifting drive mechanism 122 may include a rotary drive member, a lead screw 1221 and a nut. The rotary drive member is used to drive the lead screw 1221 to rotate. The lead screw 1221 extends along the width direction F2 of the battery 200. The nut is sleeved on the lead screw 1221 and moves along the extension direction of the lead screw 1221 when the lead screw 1221 rotates. The third limiting member 121 is connected to the nut.

[0094] The rotary drive unit drives the lead screw 1221 to rotate, and the rotation of the lead screw 1221 drives the nut to move linearly along the width direction F2 of the battery 200. This allows the third limiting member 121 to move along the width direction F2 of the battery 200. The lead screw 1221 and nut working together can achieve precise displacement of the nut along the extension direction of the lead screw 1221 by controlling the rotation angle of the lead screw 1221. Since the third limiting member 121 is connected to the nut, it can move synchronously with the nut, thereby achieving precise displacement of the third limiting member 121 along the width direction F2 of the battery 200.

[0095] This allows for precise adjustment of the position of the battery 200 along the width direction F2, enabling the battery tray 100 to adapt to batteries 200 of different sizes, ensuring precise alignment between the battery 200's liquid filling port and the liquid filling connector 3, improving liquid filling accuracy, and effectively avoiding problems such as leakage or uneven liquid filling caused by alignment deviation.

[0096] Meanwhile, by adjusting the position of the third limiting member 121 along the width direction F2 of the battery 200, the battery tray 100 does not need to be replaced when processing batteries 200 of different sizes, thereby improving the production efficiency of the battery 200 and reducing production costs.

[0097] In some embodiments, the rotary drive can be an external drive or a manually driven drive.

[0098] In some embodiments, the second limiting device 12 further includes a first mounting bracket 123 and a second mounting bracket 124, which are fixedly connected to the support base 2. The first mounting bracket 123 and the second mounting bracket 124 are respectively disposed at both ends of the third limiting member 121 along the thickness direction F1 of the battery 200, and the third limiting member 121 is movable relative to the first mounting bracket 123 and the second mounting bracket 124 along the thickness direction F1 of the battery 200. A lifting drive mechanism 122 is disposed on the first mounting bracket 123 and / or the second mounting bracket 124.

[0099] In some embodiments, the lifting drive mechanism 122 further includes a bearing 125, which is sleeved on the lead screw 1221 and disposed on the first mounting bracket 123 and / or the second mounting bracket 124. The first mounting bracket 123 and / or the second mounting bracket 124 can support and fix the lifting drive mechanism 122. The bearing 125 can make the relative movement between the lead screw 1221 and the first mounting bracket 123 and / or the second mounting bracket 124 smoother, reduce wear caused by friction between them, and thus extend the service life of the battery tray 100.

[0100] In some embodiments, the lifting drive mechanism 122 may further include a retaining ring 126, which is disposed at one end of the bearing 125 and is used to limit the bearing 125 and reduce the axial movement of the bearing 125.

[0101] In some embodiments, the lifting drive mechanism 122 may further include a second gear 127, a third gear 128, and a moving member 129. The second gear 127 is coaxially arranged with and fixedly connected to the lead screw 1221. The third gear 128 is fixedly connected to the moving member 129. The moving member 129 can drive the third gear 128 to move, thereby causing the third gear 128 to mesh or disengage from the second gear 127.

[0102] When the moving part 129 drives the third gear 128 to mesh with the second gear 127, the third gear 128 can restrict the rotation of the second gear 127, thereby restricting the rotation of the lead screw 1221 and fixing the third limiting member 121 in the target position. When the moving part 129 drives the third gear 128 to disengage from the second gear 127, the second gear 127 can rotate, thereby causing the lead screw 1221 to rotate, allowing the third limiting member 121 to adjust the size of the limiting space along the width direction F2 of the battery 200 so that the battery 200 is aligned with the liquid injection connector 3.

[0103] For example, the third gear 128 can be configured as a cylindrical gear, or the third gear 128 can be configured as a linear rack.

[0104] For example, the movable element 129 may be configured as a paddle or pin, etc., with one end of the movable element 129 extending out of the first mounting bracket 123 and / or the second mounting bracket 124, so that the movable element 129 can be moved to allow the third gear 128 to be displaced.

[0105] Please refer to Figure 1 and Figure 6 , Figure 6 This is a schematic diagram of the structure of a fifth limiting member 132 provided in an embodiment of this application. In some embodiments, the third limiting device 13 may include a fourth limiting member 131 and a fifth limiting member 132, which are disposed on opposite sides of a limiting space along the length direction F3 of the battery 200. The fourth limiting member 131 and the fifth limiting member 132 can form a limiting space along the length direction F3 of the battery 200, thereby limiting the battery 200 along the length direction F3.

[0106] The fourth limiting member 131 and / or the fifth limiting member 132 can move along the length direction F3 of the battery 200 to change the distance between the fourth limiting member 131 and the fifth limiting member 132 along the length direction F3 of the battery 200, so that the length of the limiting space of the battery 200 is adjustable.

[0107] By changing the distance between the fourth limiting member 131 and the fifth limiting member 132, the battery tray 100 can be adapted to batteries 200 of different lengths, thereby positioning the batteries 200. In this way, when performing electrolyte injection processing on batteries 200 of different lengths, it is not necessary to change to battery trays 100 of different specifications, thus saving production costs and improving production efficiency.

[0108] In some embodiments, the fourth limiting member 131 and / or the fifth limiting member 132 are adjustable along the length direction F3 of the battery 200 and can be adjusted manually.

[0109] In some embodiments, the third limiting device 13 may further include a driving mechanism for driving the fourth limiting member 131 and / or the fifth limiting member 132 to move along the length direction F3. This driving mechanism makes the length adjustment of the limiting space more convenient and faster, and it allows control over the distance the fourth limiting member 131 and / or the fifth limiting member 132 move, thereby making the positioning of the battery 200 more accurate along the length direction F3 and the marking of the limiting space more precise.

[0110] The third limiting device 13 may also include a driving mechanism for driving the fourth limiting member 131 and / or the fifth limiting member 132 to move along the length direction F3 of the battery 200, so as to change the distance between the fourth limiting member 131 and the fifth limiting member 132 along the length direction F3 of the battery 200, so that the length of the limiting space of the battery 200 is adjustable.

[0111] In other embodiments, the drive mechanism can be independent of the battery tray 100. When the battery 200 needs to be installed or removed, the drive mechanism is connected to the fourth limiting member 131 and / or the fifth limiting member 132 to drive the fourth limiting member 131 and / or the fifth limiting member 132 to move along the length direction F3. After the battery 200 is placed, the fourth limiting member 131 and / or the fifth limiting member 132 reach the target position, and after adjusting the limiting space, the drive mechanism is removed.

[0112] In some embodiments, the fourth limiting member 131 is fixed relative to the support base 2, and the fifth limiting member 132 is movable along the length direction F3 of the battery 200 so that the length of the limiting space of the battery 200 is adjustable.

[0113] The fourth limiting member 131 is fixed relative to the support base 2. When the battery 200 is placed on the battery tray 100, the fourth limiting member 131 can provide a stable positioning reference in the length direction F3, reducing positioning deviation. The fifth limiting member 132 moves along the length direction F3 of the battery 200, which can adjust the length of the limiting space of the battery 200. When facing batteries 200 of different lengths, it changes its own position and cooperates with the fixed fourth limiting member 131 to form a limiting space adapted to the length of the battery 200. After the battery 200 is installed in place, the fifth limiting member 132 clamps one end of the battery 200 in the length direction F3, thereby preventing the battery 200 from shifting.

[0114] This improves the adaptability of the battery tray 100, eliminating the need to change trays when producing different batteries 200, thus increasing the production efficiency of battery 200.

[0115] In some embodiments, the fourth limiting member 131 may be integrated with the support base 2.

[0116] In some embodiments, the liquid injection connector 3 can be connected to the fourth limiting member 131 to connect one end of the battery 200 along the length direction F3, thereby injecting liquid into the battery 200.

[0117] In some embodiments, the fifth limiting member 132 is connected to the driving mechanism, which can drive the fifth limiting member 132 to move along the length direction F3 of the battery 200 so that the length of the limiting space of the battery 200 is adjustable.

[0118] The drive mechanism can output stable power according to the different length requirements of the battery 200, driving the fifth limiting member 132 to move smoothly along the length direction F3 of the battery 200. By adjusting the fifth limiting member 132 through the drive mechanism, manual intervention can be reduced, production errors can be decreased, and production efficiency can be improved.

[0119] In some embodiments, the fifth limiting member 132 includes a fifth limiting member body 1321, a second elastic member 1322, and a positioning member 1323. The fifth limiting member body 1321 is connected to the driving mechanism, the positioning member 1323 is disposed on the side of the fifth limiting member body 1321 facing the fourth limiting member 131, and the second elastic member 1322 is connected between the fifth limiting member body 1321 and the positioning member 1323.

[0120] The fifth limiting member body 1321 provides rigid support to bear the power output by the drive mechanism and transmit the power to the positioning member 1323. The positioning member 1323 is in direct contact with the battery 200 and provides a clamping force along the length direction F3 to limit the battery 200.

[0121] The second elastic element 1322 is connected between the fifth limiting element body 1321 and the positioning element 1323. It can absorb the impact force through its own deformation. When the driving mechanism pushes the fifth limiting element body 1321 closer to the battery 200, the positioning element 1323 contacts the battery 200 first. The second elastic element 1322 is then compressed and generates a reverse elastic force. This ensures that the clamping force of the positioning element 1323 on the battery 200 is stable and also prevents the rigid thrust of the driving mechanism from acting directly on the battery 200 shell, thus preventing the battery 200 from being indented or deformed due to excessive instantaneous force.

[0122] In addition, by using the positioning member 1323 as the part that directly contacts the battery 200, it is possible to avoid unstable positioning of the battery 200 caused by the elastic deformation of the second elastic member 1322, which could lead to misalignment or leakage between the battery 200 and the main connector.

[0123] In some embodiments, the support base 2 includes a second guide rail 21 that extends along the length direction F3 of the battery 200, and at least a portion of the fifth limiting member 132 is disposed on the second guide rail 21 to allow the fifth limiting member 132 to slide along a first direction.

[0124] By setting the second guide rail 21, the movement of the fifth limiting member 132 can be guided. In this way, the movement direction of the fifth limiting member 132 is more accurate, avoiding positioning errors of the battery 200 caused by the movement deviation of the fifth limiting member 132, thereby further improving the accuracy and stability of the battery 200.

[0125] In some embodiments, the second guide rail 21 can be configured as a guide groove, and the fifth limiting member body 1321 is provided with a slider that cooperates with the guide groove. The slider can slide in the guide groove along the extension direction of the second guide rail 21, thereby causing the fifth limiting member 132 to be displaced along the length direction F3 of the battery 200, so as to realize the length adjustment of the limiting space of the battery 200.

[0126] Since the fifth limiting member 132 can move along the length direction F3 of the battery 200, thereby adjusting the length of the limiting space of the battery 200, after the battery 200 is installed on the battery tray 100, the fifth mounting member needs to be locked to prevent the fifth mounting member from continuing to move. Only in this way can the battery 200 be clamped and limited, preventing the battery 200 from shifting or moving during the production process.

[0127] Please refer to Figure 1 , Figure 6 and Figure 7 , Figure 7 This is a schematic diagram of a locking mechanism 133 provided in an embodiment of this application. Therefore, in some embodiments, the third limiting device 13 further includes a locking mechanism 133. The locking mechanism 133 is connected to the fifth limiting member 132. When the fifth limiting member 132 moves to the target position along the length direction F3 of the battery 200, the locking mechanism 133 can cooperate with the support base 2 to lock the position of the fifth limiting member 132 along the length direction F3 of the battery 200.

[0128] The locking mechanism 133 is connected to the fifth limiting member 132. When the fifth limiting member 132 moves to the target position along the length direction F3 of the battery 200, the locking mechanism 133 can lock the position of the fifth limiting member 132 along the length direction F3 of the battery 200. In this way, when the locking mechanism 133 locks the fifth limiting member 132, the fifth limiting member 132 can cooperate with the fourth limiting member 131 to limit the length direction F3 of the battery 200. When the locking mechanism 133 unlocks the fifth limiting member 132, the fifth limiting member 132 can move along the length direction F3 of the battery 200, thereby realizing the adjustable limiting space of the length direction F3 of the battery 200.

[0129] In some embodiments, the locking mechanism 133 includes a locking mechanism body 1331 and a locking member 1332. The locking mechanism body 1331 is connected to the fifth limiting member 132, and the locking member 1332 fixes the locking mechanism body 1331 to the target position of the support 2.

[0130] By cooperating with the locking element 1332, the locking mechanism body 1331 can be locked and unlocked. Since the locking mechanism body 1331 is connected to the fifth limiting element 132, the locking and unlocking of the fifth limiting element 132 can be achieved by locking and unlocking the locking mechanism body 1331, thereby enabling the battery 200 to be fixedly limited and disassembled.

[0131] In some embodiments, the locking member 1332 can be configured as a plug-in member, and the support base 2 can be provided with positioning holes arranged at intervals along the length direction F3 of the battery 200. When the plug-in member is inserted into the positioning hole, the locking mechanism body 1331 is locked. When the plug-in member is pulled out of the positioning hole, the locking mechanism body 1331 can move along the length direction F3 of the battery 200.

[0132] The support base 2 has positioning holes spaced along the length direction F3 of the battery 200, which allows for the fixed-position adjustment of the locking mechanism body 1331, thereby achieving compatibility in the length direction F3 of the battery 200. Thus, when the length of the battery 200 changes within a small range, there is no need to repeatedly adjust the position of the locking mechanism 133; the elastic action of the second elastic element 1322 can meet the adjustment requirements in the length direction F3 of the battery 200.

[0133] In some embodiments, the connector may penetrate the locking mechanism body 1331, and a portion of the locking mechanism body 1331 is disposed at the end of the connector away from the support base 2 along the direction of movement of the connector. The locking mechanism 133 also includes a baffle 1334, which is fixedly connected to the connector, and a portion of the baffle 1334 is spaced apart from a portion of the locking mechanism body 1331 along the direction of movement of the connector. The locking mechanism 133 also includes a third elastic member 1333, which is sleeved on the connector and located between the portion of the baffle 1334 and the portion of the locking mechanism body 1331. The third elastic member 1333 is used to support the portion of the baffle 1334 away from the locking mechanism body 1331, so that the connector is held in the positioning hole.

[0134] Therefore, when the fifth limiting member 132 needs to be unlocked, the third elastic member 1333 is compressed by moving the baffle 1334, so that the part of the plug-in located in the positioning hole is disengaged from the positioning hole, thereby enabling the fifth limiting member 132 to move.

[0135] When the fifth limiting member 132 needs to be locked, the baffle 1334 is released, and the third elastic member 1333 supports the portion of the baffle 1334 away from the locking mechanism body 1331, thereby keeping at least a portion of the plug-in member in the positioning hole and locking the fifth limiting member 132.

[0136] In some embodiments, the locking mechanism body 1331 is detachably connected to the fifth mounting member. This allows for easy installation when the battery 200 model remains unchanged and only the battery 200 is being replaced for batch processing; simply moving the fifth mounting member is sufficient to loosen the battery 200 and allow for its installation. When installing a new batch of batteries 200 of the same specification, only the fifth mounting member and the locking mechanism body 1331 need to be installed, eliminating the need for repeated positioning in the length direction F3. This saves production time and improves production efficiency.

[0137] In some embodiments, the locking mechanism body 1331 is engaged with the fifth limiting member 132. This engagement allows for the detachment of the locking mechanism body 1331 and the fifth limiting member 132, simplifying disassembly and installation and improving production efficiency.

[0138] In some embodiments, the locking mechanism body 1331 may be provided with a limiting slot 1335 facing the fifth limiting member 132. The fifth limiting member 132 may include a limiting block 1324, which can cooperate with the limiting slot 1335 to realize the connection between the fifth limiting member 132 and the locking mechanism body 1331.

[0139] Specifically, the fifth limiting member 132 may further include a rotating shaft 1325, which passes through the limiting block 1324 and the fifth limiting member body 1321, allowing the limiting block 1324 to rotate relative to the fifth limiting member body 1321 around the axis of the rotating shaft 1325. The fifth limiting member 132 may also include a fourth elastic member 1326, which connects the limiting block 1324 and the fifth limiting member body 1321 along the rotation direction of the limiting block 1324. When the fourth elastic member 1326 is compressed, the limiting block 1324 can disengage from the limiting slot 1335; when the fourth limiting member 131 resets, the limiting block 1324 resets and can connect with the limiting slot 1335.

[0140] In some embodiments, the support base 2 further includes a third guide rail 22, which extends along the length direction F3 of the battery 200; the locking mechanism body 1331 is disposed on the third guide rail 22 so that the locking mechanism body 1331 slides relative to the support base 2 along the length direction F3 of the battery 200; the locking member 1332 can lock the locking mechanism body 1331.

[0141] In this way, the locking mechanism 133 can also move relative to the support base 2 along the length direction F3 of the battery 200. The movement of the locking mechanism 133 can drive the fifth limiting member 132 to move along the length direction F3 of the battery 200, thereby realizing the length adjustment of the limiting space of the battery 200.

[0142] The locking mechanism body 1331 and the fifth limiting member 132 are configured as separate structures, and both the locking mechanism body 1331 and the fifth limiting member 132 can slide along the length direction F3 of the battery 200. Thus, when only the batch of batteries 200 is replaced without changing the battery model, only the fifth limiting member 132 is moved, while the locking mechanism body 1331 remains in its original position. Therefore, when reinstalling the battery 200 onto the battery tray 100, the fifth limiting member 132 is simply moved to connect with the locking mechanism body 1331 to achieve battery positioning. When changing the size and model of the battery 200, the locking mechanism body 1331 is moved again to accommodate the new battery size and model.

[0143] Please refer to Figure 1 and Figure 8 , Figure 8 This is a schematic diagram of the structure of a fixing device 4 provided in an embodiment of this application. In some embodiments of this application, in order to facilitate the stable connection of the battery 200 to the battery tray 100 so that the liquid injection connector 3 can be well connected with the battery 200, the battery tray 100 may also include a fixing device 4. The fixing device 4 is connected to the support base 2 and is used to clamp the battery 200 so that the battery 200 is fixed on the battery tray 100.

[0144] In some embodiments, the fixing device 4 can be connected to the fourth limiting member 131, so that the fixing device 4 can fix one end of the battery 200 in the length direction F3, preventing the battery 200 from shifting or shaking in the thickness direction F1 or the width direction F2, causing poor connection between the battery 200 and the liquid injection connector 3, thereby causing leakage and other faults.

[0145] In some embodiments, the fixing device 4 may include a first locking plate 41 and a second locking plate 42 spaced apart along the thickness direction F1 of the battery 200, and the first locking plate 41 and the second locking plate 42 are movable along the thickness direction F1 of the battery 200. The gap between the first locking plate 41 and the second locking plate 42 can be used to accommodate the battery 200. When the gap between the first locking plate 41 and the second locking plate 42 decreases, the first locking plate 41 and the second locking plate 42 can clamp the battery 200. When the gap between the first locking plate 41 and the second locking plate 42 increases, the battery 200 can be released, thereby allowing the battery 200 to be installed or removed.

[0146] This allows the battery 200 to be fixed in place, preventing relative displacement between the battery 200 and the battery tray 100 due to vibration or pressure changes, thereby ensuring the stability of the electrolyte filling of the battery 200 and the accuracy of the battery tray 100 in positioning the battery 200.

[0147] In some embodiments, a pressure plate 43 is provided at the middle of the first locking plate 41 and the second locking plate 42. The pressure plate 43 is used to connect the first locking plate 41 and the second locking plate 42 to the support base 2, and to restrict the displacement of the first locking plate 41 and the second locking plate 42 along the length direction F3 of the battery 200, and to enable the first locking plate 41 and the second locking plate 42 to move relative to the support base 2 along the thickness direction F1 of the battery 200.

[0148] In this way, by displacing the first locking piece 41 and the second locking piece 42 along the thickness direction F1 of the battery 200, the fixing device 4 can clamp or loosen the battery 200, thereby achieving the fixing and disassembly of the battery 200.

[0149] In some embodiments, the fixing device 4 may further include a pull rod 44 along the length F3 of the battery 200. The ends of the first locking plate 41 and the second locking plate 42 facing away from the battery 200 are connected to the pull rod 44, and the ends of the first locking plate 41 and the second locking plate 42 near the battery 200 are used to clamp the battery 200. When the pull rod 44 approaches the first locking plate 41 and the second locking plate 42, due to the pushing force of the pull rod 44, the first locking plate 41 and the second locking plate 42 are pushed apart, and the first locking plate 41 and the second locking plate 42 move away from each other, increasing the gap between the first locking plate 41 and the second locking plate 42. In this way, the first locking plate 41 and the second locking plate 42 can be released from the battery 200, making it easier to disassemble, install, and replace the battery 200.

[0150] When the pull rod 44 moves away from the first locking plate 41 and the second locking plate 42, the first locking plate 41 and the second locking plate 42 are pulled closer to each other by the pulling force of the pull rod 44, and the gap between the first locking plate 41 and the second locking plate 42 is reduced. In this way, the first locking plate 41 and the second locking plate 42 can apply a clamping force to the battery 200 located in the gap between them, thereby clamping the battery 200 and fixing the battery 200.

[0151] In some embodiments, the fixing device 4 may further include a limiting block 45 and a fifth elastic element 46. The limiting block 45 is fixedly connected to the support base 2, the pull rod 44 passes through the limiting block 45, and the fifth elastic element 46 is sleeved on the pull rod 44. When an external force is applied to the pull rod 44, causing the pull rod 44 to approach the first locking piece 41 and the second locking piece 42, the fifth elastic element 46 is compressed inside the limiting block 45, which can store elastic potential energy. At this time, the first locking piece 41 and the second locking piece 42 are pushed apart, and the first locking piece 41 and the second locking piece 42 move away from each other, increasing the gap between the first locking piece 41 and the second locking piece 42, which can release the battery 200, making it easier to disassemble and replace the battery 200.

[0152] When the external force applied to the lever 44 is removed, the fifth elastic element 46 releases its elastic potential energy, which allows the lever 44 to move away from the first locking plate 41 and the second locking plate 42. The first locking plate 41 and the second locking plate 42 are pulled closer to each other by the pulling force of the lever 44, and the gap between the first locking plate 41 and the second locking plate 42 is reduced, thereby clamping the battery 200.

[0153] Specifically, the connection between the interior of the limiting block 45 and the fifth elastic element 46 and the pull rod 44 can be referred to the layout of the locking mechanism body 1331, the third elastic element 1333 and the plug in the third limiting device 13, which will not be described in detail here.

[0154] In some embodiments of this application, since the battery tray 100 can simultaneously install multiple batteries 200, the fixing device 4 may include multiple first locking plates 41 and multiple second locking plates 42. The multiple first locking plates 41 and multiple second locking plates 42 are respectively arranged at intervals along the thickness direction F1 of the battery 200, and each first locking plate 41 and each second locking plate 42 are arranged at intervals in a one-to-one correspondence.

[0155] In this way, multiple batteries 200 can be clamped and fixed at the same time, so that multiple batteries 200 can be injected and processed at the same time within the battery tray 100.

[0156] Accordingly, embodiments of this application may also include multiple pull rods 44, each pull rod 44 being connected to a first locking plate 41 and a second locking plate 42 respectively.

[0157] In some embodiments, in order to apply external force to multiple levers 44 simultaneously, the fixing device 4 may further include a connecting block 47 and a handle 48. The ends of the multiple levers 44 away from the first locking piece 41 and the second locking piece 42 are all connected to the connecting block 47, and the handle 48 is disposed on the connecting block 47. In this way, when a force is applied to the handle 48, the force can be transmitted to the connecting block 47, and then to the multiple levers 44, thereby driving the multiple first locking pieces 41 and the second locking pieces 42 to move along the thickness direction F1 of the battery 200, thereby achieving clamping and loosening of the battery 200.

[0158] Please refer to Figure 1 and Figure 9 , Figure 9 This is a schematic diagram of a support base 2 provided in an embodiment of this application. In some embodiments of this application, the support base 2 may include a support base body 23, which is used to support the limiting device 1, the liquid injection connector 3, the fixing device 4, and the battery 200. In one possible structural design, the support base body 23 may be a plate-like structure to support components such as the limiting device 1 and the fixing device 4. In another possible structural design, the support base body 23 may also be configured as a grid structure, connected by supporting crossbeams and supporting longitudinal beams to support the limiting device 1 and the fixing device 4.

[0159] In some embodiments, the battery tray 100 may further include a shock absorber 5, which is connected to the edge of the support body 23 along the length direction F3 and the thickness direction F1 of the battery 200. This provides protection for the battery tray 100, preventing damage caused by impacts.

[0160] In some embodiments, the battery tray 100 may further include a code carrier 6, which can identify the model of the battery 200 to adjust and control the process parameters of the battery 200, and can record liquid injection process data to achieve process monitoring. This facilitates traceability and recording of the battery 200 production process and helps to improve the standardization of battery 200 production.

[0161] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0162] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
