Description

Technical Field

[0001] This application relates to the field of battery device technology, and in particular to a support device and a battery production line. Background Technology

[0002] With the rapid development of the battery industry, battery packs, as battery encapsulation structures that combine multiple battery cells through mechanical structures and electrical connections, are becoming increasingly complex in design and demanding in manufacturing. However, in the process of shaping and pressurizing the terminal posts and curing the structural adhesive after the battery cells are placed in the pack, the layout of the reinforcing ribs and the locking points at the bottom of the lower casing differs for different product models, requiring the separate fabrication of a support mechanism for each product, resulting in high production costs. Utility Model Content

[0003] In view of the above problems, this application provides a support device and a battery production line, which aims to reduce the production cost of battery devices.

[0004] In a first aspect, this application provides a support device for supporting a battery device. The support device includes a support base and a plurality of support members. The support base has a reference surface. The plurality of support members are disposed on the support base corresponding to different areas of the reference surface. The support members have a support surface for supporting the battery device. The height of the support surface of at least some of the support members relative to the reference surface is adjustable, and / or, at least some of the support members are movable in a direction substantially parallel to the reference surface to change the support position.

[0005] In the technical solution of this application embodiment, by setting multiple support members on the bearing base and making the height of the support surface of at least some of the support members adjustable and / or the position movable, the support position and / or support height of at least some of the support members can be flexibly adjusted according to the differences in the layout of the reinforcing ribs and locking points at the bottom of the lower box of different battery devices. In this way, the support device can be adapted to multiple models of products without the need to manufacture a separate support mechanism for each product, thereby helping to reduce production costs.

[0006] In some embodiments, the plurality of support members include a first support member and a second support member; the first support member is fixedly installed on the bearing substrate; the height of the support surface of the second support member relative to the reference plane is adjustable, and / or, at least a portion of the second support member can be adjusted in its installation position on the bearing substrate along a direction substantially parallel to the reference plane. This ensures both the stability of the support and improves the versatility of the support device.

[0007] In some embodiments, there are multiple first support members, which are arranged sequentially at intervals along a first direction, and each of the multiple first support members extends along a second direction; the first and second directions are substantially perpendicular; at least one second support member is provided between two adjacent first support members. This further improves the versatility of the support device.

[0008] In some embodiments, the support device further includes a heating element disposed on the side of the first support member facing away from the substrate. This helps to shorten the curing time.

[0009] In some embodiments, there are multiple first support members and multiple heating members; the first support members and heating members are arranged in a one-to-one correspondence.

[0010] In some embodiments, the heating element includes a heating plate, a heating mounting plate, and a heating support plate; the heating mounting plate is disposed on the first support member, and the heating support plate is disposed on the side of the heating mounting plate facing away from the first support member; the heating plate is disposed between the heating mounting plate and the heating support plate. This improves the heating uniformity of the supported battery device, reduces heat loss, and minimizes the thermal impact on the supporting substrate.

[0011] In some embodiments, the heating element further includes a thermally conductive adhesive component disposed on the side of the heating support plate facing away from the heating mounting plate. This helps to improve heat transfer efficiency and reduce damage caused by rigid contact between the bottom of the battery device and the heating support plate.

[0012] In some embodiments, the supporting base includes a first support plate and a second support plate disposed opposite to each other; the surface of the first support plate defines a reference plane, the second support plate is disposed above the first support plate, and the distance between the first and second support plates is adjustable; a first support member and a second support member are both disposed on the second support plate; a portion of the plurality of support members constitutes a third support member, which is disposed on the first support plate. This facilitates further improvement in the versatility of the support device.

[0013] In some embodiments, the support device further includes a frame and a drive mechanism, with the first support plate and the second support plate respectively disposed on the frame; the drive mechanism is used to drive the first support plate to move along a first direction to change the support position of the third support member relative to the other support members. This helps to improve the overall stability of the support device.

[0014] In some embodiments, the reference plane has a main region and two edge regions, the two edge regions being located on opposite sides of the main region; the orthographic projection of the second support plate onto the first support plate at least partially covers the main region; and a third support member is disposed on the first support plate corresponding to the edge region. Thus, by providing a third support member in the edge region, additional support can be provided for the edge portion of the battery device, improving the stability and uniformity of the support.

[0015] In some embodiments, the main body region and two edge regions are arranged side by side along a second direction; each edge region is provided with a plurality of third supports, which are arranged at intervals along a first direction. This facilitates further increasing the supported area of ​​the battery device.

[0016] In some embodiments, the third support member includes a first stepped portion and a second stepped portion, the first stepped portion being located on the side of the second stepped portion closer to the main body area; the height difference between the first stepped portion and the reference surface is smaller than the height difference between the second stepped portion and the reference surface. This facilitates further increasing the supported area of ​​the battery device.

[0017] In some embodiments, the support member whose supporting surface can be adjusted in height relative to the reference plane is an adjustable support member; the adjustable support member includes a plurality of support blocks, which are stacked sequentially along the direction perpendicular to the reference plane; the adjustable support member is configured to adjust the height of its supporting surface relative to the reference plane by increasing or decreasing the number of support blocks. Thus, a height adjustment method that is simple in structure, low in cost, and structurally stable is provided.

[0018] In some embodiments, the supporting surfaces of at least two support members have different areas, and / or the supporting surfaces of at least two support members have different profiles. This is advantageous for further increasing the supporting area of ​​the battery device, thereby helping to reduce deformation or stress concentration caused by improper support.

[0019] Secondly, this application also proposes a battery production line, which includes the support device of any of the foregoing embodiments.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0032] With the rapid development of the battery industry, battery packs, as battery encapsulation structures that combine multiple battery cells through mechanical structures and electrical connections, are becoming increasingly complex in design and demanding in manufacturing. However, in the process of shaping and pressurizing the terminal posts and curing the structural adhesive after the battery cells are placed in the pack, the layout of the reinforcing ribs and the locking points at the bottom of the lower box differs for different product models. This necessitates the manufacture of a separate support mechanism for each product, which is not only costly but also time-consuming for model changes.

[0033] In addition, the excessive curing time of structural adhesives severely restricts production cycle and easily leads to quality risks such as insufficient bonding strength and poor bonding.

[0034] Based on the above considerations, in order to solve the problem that the support mechanism needs to be made separately for each product due to the difference in the bottom structure of the lower box of different product models, a support device is designed. The support device includes a bearing base and multiple support members. The bearing base has a reference surface. The multiple support members are respectively disposed on the bearing base corresponding to different areas of the reference surface. The support members have a support surface for supporting the battery device. The height of the support surface of at least some support members relative to the reference surface is adjustable, and / or, at least some support members can move in a direction that is approximately parallel to the reference surface to change the support position.

[0035] In the technical solution of this application, by setting multiple support members on the bearing base and making the height of the support surface of at least some of the support members adjustable and / or the position movable, the support position and / or support height of at least some of the support members can be flexibly adjusted according to the differences in the layout of the reinforcing ribs and locking points at the bottom of the lower box of different battery devices. In this way, the support device can be adapted to multiple models of products without the need to manufacture a separate support mechanism for each product, thereby helping to reduce production costs.

[0036] Furthermore, by integrating heating elements into the load-bearing device to heat the battery assembly, the curing of the structural adhesive can be accelerated, the curing time shortened, and curing can be carried out using the transfer time, thereby increasing the production cycle and mitigating quality risks such as insufficient adhesive strength and poor bonding.

[0037] According to some embodiments of this application, please refer to Figures 1 to 7The support device 10 includes a support base 100 and a plurality of support members 200. The support base 100 has a reference surface 101, and the plurality of support members 200 are respectively disposed on the support base 100 corresponding to different areas of the reference surface 101. Each support member 200 has a support surface 201 for supporting the battery device. The height of the support surface 201 of at least some of the support members 200 relative to the reference surface 101 is adjustable, and / or, at least some of the support members 200 are movable in a direction substantially parallel to the reference surface 101 to change their support position.

[0038] The supporting base 100 is the main structure of the supporting device, and can be a plate structure, frame structure, etc., without limitation. The supporting base 100 can be a pallet or a logistics cart with a pallet. The specific type can be determined according to the actual situation, and this specification does not limit this embodiment. The reference surface 101 is usually the upper surface of the supporting base 100, and the reference surface 101 can be a plane.

[0039] The number of support components 200 can be two, three, four or more. Multiple support components 200 can be set in different areas of the reference surface 101 according to the layout of the reinforcing ribs and the position of the locking points at the bottom of the battery pack. The support components 200 can be set on the bearing base 100 by means of sliding connection, detachable connection or other methods.

[0040] The support surface 201 is the surface on the support member 200 that is in contact with the battery device. The support surface 201 can be a plane, or a curved surface or stepped surface that is adapted to the bottom structure of the battery device.

[0041] In use, based on the layout of the reinforcing ribs and the position of the locking points at the bottom of the lower casing of the battery device to be processed, adjust the position of at least some of the support members 200 on the bearing base 100 and / or the height of the support surface 201 so that the total support surface formed by the support surfaces 201 of each support member 200 can adapt to the bottom shape of the battery device. This helps to increase the supported area at the bottom of the battery device, thereby helping to reduce the risk of deformation or local stress concentration of the battery device during pressure or curing.

[0042] When it is necessary to replace the battery device with a different model, the position and / or height of each support component 200 can be readjusted according to the bottom structure of the lower casing of the new battery device. In this way, it is not necessary to remake the entire support mechanism, thereby reducing production costs.

[0043] At least a portion of the support member 200 is capable of moving in a direction substantially parallel to the reference plane 101. "Substantially parallel" means that a slight angular deviation due to machining or assembly tolerances is permissible between the direction of movement of the support member 200 and the reference plane 101, provided that the support member 200 can smoothly adjust its position along the plate direction of the supporting substrate 100, typically not exceeding 5°. This movement adjustment aims to change the support position of the support member 200 to accommodate the layout of the bottom reinforcing ribs of different battery devices.

[0044] In the technical solution of this application embodiment, by setting multiple support members 200 on the support base 100, and making the height of the support surface 201 of at least some of the support members 200 adjustable and / or the position movable, the support position and / or support height of at least some of the support members 200 can be flexibly adjusted according to the differences in the layout of the reinforcing ribs and locking points at the bottom of the lower casing of different battery devices. In this way, the support device 10 can be adapted to multiple models of products without the need to manufacture a separate support mechanism for each product, thereby helping to reduce production costs.

[0045] Furthermore, in this application, when the term "approximately" is used to modify directional or positional relationships, it means that minor deviations caused by machining, assembly, or measurement tolerances are permissible, and such deviations do not affect the implementation effect of the technical solution of this application. Unless otherwise stated, the deviation range is generally no more than 5°.

[0046] According to some embodiments of this application, please refer to Figure 2 and Figure 3 The plurality of support members 200 include a first support member 210 and a second support member 220. The first support member 210 is fixedly mounted to the support base 100. The height of the support surface 201 of the second support member 220 relative to the reference surface 101 is adjustable, and / or, at least a portion of the second support member 220 is adjustable in its mounting position on the support base 100 in a direction substantially parallel to the reference surface 101.

[0047] The first support member 210 serves as a fixed basic support structure, while the second support member 220 serves as an adjustable auxiliary support structure. Generally, the first support member 210 can be fixed to the bearing base 100 by bolts, welding, or snap-fitting. The second support member 220 can be slidably connected to the bearing base 100 via a sliding seat, guide rail, or other structure to adjust its installation position. The second support member 220 may include multiple support blocks 261, and is configured to adjust the height of the support surface 201 relative to the reference surface 101 by increasing or decreasing the number of support blocks 261. Furthermore, the second support member 220 can also adjust the height of the support surface 201 relative to the reference surface 101 via a lifting rod, threaded adjusting rod, or other structure.

[0048] In this way, the fixed first support 210 can provide a stable foundation support for the battery device, while the adjustable second support 220 can be flexibly adjusted according to the differences in the layout of the reinforcing ribs at the bottom of the lower casing of different battery devices, which not only ensures the stability of the support, but also improves the versatility of the support device 10.

[0049] According to some embodiments of this application, please refer to Figure 2 and Figure 3 There are multiple first support members 210, which are arranged at intervals along a first direction x, and extend along a second direction y. The first direction x and the second direction y are approximately perpendicular. At least one second support member 220 is provided between two adjacent first support members 210.

[0050] Generally, the first direction x can be the length direction of the bearing substrate 100, and the second direction y can be the width direction of the bearing substrate 100; alternatively, the second direction y can be the length direction of the bearing substrate 100, and the first direction x can be the width direction of the bearing substrate 100.

[0051] Multiple first support members 210 are arranged at intervals along a first direction x, defining multiple strip-shaped support structures extending along a second direction y. A second support member 220 is provided between two adjacent first support members 210, that is, between two first support members of fixed height, a second support member with adjustable height or position is added, which can further improve the versatility of the support device 10.

[0052] It is understood that the first support member 210 can be a long strip support bar extending along the second direction y, and the second support member 220 can be a long strip support bar, a block or a short strip support block 261.

[0053] According to some embodiments of this application, please refer to Figure 2 and Figure 3 The height of the support surface 201 of the second support member 220, which is located between the two first support members 210, relative to the reference surface 101 is adjustable.

[0054] Generally, the second support member 220, located between the two first support members 210, is mainly used to support the area between adjacent reinforcing ribs at the bottom of the lower housing of the battery device. Since the structure of different models of battery devices may differ in this area, by making the height of the support surface 201 of the second support member 220 adjustable, the second support member 220 can better fit the bottom of the battery device, providing uniform support force and reducing deformation or damage to the battery device caused by local suspension or overpressure.

[0055] According to some embodiments of this application, please refer to Figure 3 and Figure 7 The support device 10 also includes a heating element 300, which is located on the side of the first support 210 facing away from the support base 100.

[0056] The heating element 300 can be a heating plate 320, a heating tube, a heating film, a heating wire, or other structures; the number of heating elements 300 can be one or more. The heating element 300 is disposed on the side of the first support member 210 facing away from the supporting base 100; exemplarily, the supporting base 100 is located below the first support member 210, and the first support member 210 has a lower surface facing the supporting base 100 and an upper surface facing away from the supporting base 100. The heating element 300 is disposed on the upper surface side of the first support member 210, that is, on the side of the first support member 210 away from the supporting base 100.

[0057] In the structural adhesive curing process after the battery cells are placed in the casing, the battery assembly typically needs to be heated to accelerate the curing of the structural adhesive. In this embodiment, by providing a heating element 300 on the side of the first support 210 facing away from the supporting substrate 100, the battery assembly can be heated simultaneously with its support, achieving an integration of support and heating functions. The heating element 300 directly heats the bottom of the battery assembly, and the heat is conducted through the lower casing of the battery assembly to the location of the structural adhesive, thereby accelerating the curing reaction of the structural adhesive, shortening the curing time, and increasing production cycle time.

[0058] According to some embodiments of this application, please refer to Figure 2 and Figure 3 There are multiple first support members 210 and multiple heating elements 300, and the first support members 210 and heating elements 300 are set in a one-to-one correspondence.

[0059] Generally, each first support member 210 is provided with a corresponding heating element 300. Each heating element 300 can be controlled independently or together. When each heating element 300 can be controlled independently, the heating power and heating time of each heating element 300 can be controlled according to the heating requirements of different areas of the battery device to achieve zoned heating and reduce energy waste while ensuring the uniformity of structural adhesive curing.

[0060] According to some embodiments of this application, please refer to Figure 7 The heating element 300 includes a heating plate 320, a heating mounting plate 310, and a heating support plate 330; the heating mounting plate 310 is disposed on the first support member 210, and the heating support plate 330 is disposed on the side of the heating mounting plate 310 facing away from the first support member 210; the heating plate 320 is disposed between the heating mounting plate 310 and the heating support plate 330.

[0061] The heating mounting plate 310 is fixed to the side of the first support member 210 facing away from the support base 100. The heating mounting plate 310 can be fixed to the first support member 210 by means of bolt connection, welding or snap-fit. In some embodiments, the heating mounting plate 310 is made of a low thermal conductivity material to block heat transfer downward, reduce heat loss and protect the tray base and other components from overheating; wherein, the low thermal conductivity material is typically a material with a thermal conductivity of less than 0.2 W / (m·K), such as wood or plastic block.

[0062] The heating plate 320 serves as the main heat source, and its interior contains a resistance heating wire or heating film that generates heat when energized. The heating plate 320 can be of various types, including resistance heating plate 320 and ceramic heating plate 320.

[0063] The heating support plate 330 is made of a rigid material with good thermal conductivity, such as an aluminum plate or copper plate. The lower surface of the heating support plate 330 can be in contact with the upper surface of the heating plate 320. The upper surface of the heating support plate 330 is used to contact the bottom of the battery device or the thermally conductive adhesive part 340. The heating support plate 330 serves as both a structural base plate supporting the battery device, providing a flat support surface for the heating area, and a means to conduct the localized heat generated by the heating plate 320 into a uniform surface heat source, resulting in more even heating of the bottom of the battery device.

[0064] Optionally, the thickness of the heating mounting plate 310 and the heating support plate 330 can be selected according to the required heat conduction rate and structural strength, which is not limited in this embodiment of the specification.

[0065] Thus, by installing the heating plate 320 between the heating mounting plate and the heating support plate 330, the heat generated by the heating plate 320 is directly transferred upward to the heating support plate 330, and then transferred to the bottom of the battery device through the heating support plate 330. This helps to improve the heating uniformity of the battery device being supported, as well as reduce heat loss and reduce the thermal impact on the supporting substrate 100.

[0066] Please refer to some embodiments of this application. Figure 7 The heating element 300 also includes a thermally conductive adhesive element 340, which is disposed on the side of the heating support plate 330 facing away from the first support element 210.

[0067] The thermally conductive adhesive component 340 is disposed on the upper surface of the heating support plate 330, that is, on the side of the heating support plate 330 that contacts the battery device. The thermally conductive adhesive component 340 has good thermal conductivity and a certain degree of flexibility. It can be a thermally conductive silicone pad, a thermally conductive phase change material, etc., regardless of the application.

[0068] In this way, the thermally conductive adhesive 340 can fill the gap between the heating support plate 330 and the bottom of the battery device, improving heat conduction efficiency and allowing heat to be transferred more evenly to the bottom of the battery device. At the same time, the thermally conductive adhesive 340 can also act as a buffer, reducing the risk of damage caused by rigid contact between the bottom of the battery device and the heating support plate 330.

[0069] According to some embodiments of this application, please refer to Figure 2 The supporting base 100 includes a first support plate 110 and a second support plate 120 disposed opposite to each other. The surface of the first support plate 110 defines a reference plane 101, and the second support plate 120 is disposed above the first support plate 110. The distance between the first support plate 110 and the second support plate 120 is adjustable. A first support member 210 and a second support member 220 are both disposed on the second support plate 120. A portion of the plurality of support members 200 constitutes a third support member 230, which is disposed on the first support plate 110.

[0070] The support base 100 includes a first support plate 110 and a second support plate 120. The surface of the first support plate 110 defines a reference surface 101 for height positioning.

[0071] The first support plate 110 and the second support plate 120 are arranged opposite to each other, with the second support plate 120 positioned above the first support plate 110. The vertical projections of the first support plate 110 and the second support plate 120 overlap.

[0072] The second support plate 120 is disposed above the first support plate 110. The second support plate 120 can be directly installed on the first support plate 110 or installed on the frame 400 described below, both of which can realize the height adjustment function relative to the first support plate 110.

[0073] The distance between the first support plate 110 and the second support plate 120 is adjustable. That is, there is an adjustable distance between them in the vertical direction. This adjustable distance allows the support members respectively set on the different support plates to be adapted to battery devices of different sizes or specifications.

[0074] Furthermore, the first support member 210 and the second support member 220 are both disposed on one of the surfaces (e.g., the upper surface) of the second support plate 120, and move synchronously with the rise and fall of the second support plate 120. The third support member 230 is disposed on the first support plate 110, and the height of its support surface 201 does not change with the rise and fall of the second support plate 120. The surface of the first support plate 110 (i.e., the reference surface 101) is arranged approximately parallel to the surface of the second support plate 120.

[0075] A spacing adjustment mechanism can be provided between the first support plate 110 and the second support plate 120. This spacing adjustment mechanism can be any one of a telescopic sleeve, a hydraulic lifting rod, or an electric push rod, but is not limited to these. Through this spacing adjustment mechanism, the relative height between the second support plate 120 and the first support plate 110 can be flexibly adjusted, thereby enabling the support surface 201, which is jointly formed by the first support member 210, the second support member 220, and the third support member 230, to quickly adapt to the support height requirements of various battery device models, thus further improving the versatility of the support device 10.

[0076] According to some embodiments of this application, please refer to Figure 6 The support device 10 also includes a frame 400 and a drive mechanism 500. The first support plate 110 and the second support plate 120 are respectively disposed on the frame 400. The drive mechanism 500 is used to drive the first support plate 110 to move along the first direction x, so as to change the support position of the third support member 230 relative to the other support members 200.

[0077] The frame 400 serves as the supporting skeleton of the support device 10, providing an installation base for the first support plate 110 and the second support plate 120. The frame 400 can adopt a frame structure, a plate structure, or other forms, which are not limited in this embodiment.

[0078] The second support plate 120 is fixedly installed on the frame 400, maintaining its position. A guide structure, such as a guide rail and slider cooperation structure, is provided between the first support plate 110 and the frame 400, so that the first support plate 110 can slide smoothly relative to the frame 400 along the first direction x.

[0079] The drive mechanism 500 is connected between the first support plate 110 and the frame 400, and is used to provide driving force for the movement of the first support plate 110. The drive mechanism 500 can be implemented in various forms. For example, as... Figure 6 As shown, the drive mechanism 500 includes a lead screw and nut assembly and a drive motor. The lead screw is rotatably mounted on the frame 400 and extends along the first direction x. The nut is fixed to the first support plate 110 and threadedly engages with the lead screw. The drive motor drives the lead screw to rotate, thereby causing the first support plate 110 to move along the first direction x. Alternatively, the drive mechanism 500 can also be directly driven by a linear motor, cylinder, or hydraulic cylinder, etc., to move the first support plate 110 by extending or retracting a telescopic rod. This embodiment of the specification does not limit this approach.

[0080] Thus, the first support plate 110 is moved along the first direction x by the drive mechanism 500, and the third support member 230, as the support member 200 disposed on the first support plate 110, also changes its support position along the first direction x, while the positions of the first support member 210 and the second support member 220 disposed on the second support plate 120 remain unchanged. In this way, the relative position of the third support member 230 with respect to the first support member 210 and the second support member 220 changes, thereby changing the distribution position of the support points in the edge area; in addition, the first support member 210 and the second support member 220 correspond to the main support area of ​​the support device 10, and keeping the positions of the first support member 210 and the second support member 220 relative to the frame 400 unchanged is beneficial to improving the overall stability of the support device 10.

[0081] Optionally, the drive mechanism 500 also includes a locking element for locking the first support plate 110 to the frame 400 after the first support plate 110 has been moved to the target position.

[0082] Optionally, multiple sets of rollers 600 can be installed under the frame 400, so that the support device 10 can carry the battery device between different workstations.

[0083] According to some embodiments of this application, please refer to Figures 4 to 6 The reference plane 101 has a main area and two edge areas, which are located on opposite sides of the main area. The orthographic projection of the second support plate 120 onto the first support plate 110 at least partially covers the main area. A portion of the plurality of supports 200 is a third support 230, and the edge area of ​​the third support 230 is located on the first support plate 110.

[0084] The reference plane 101 is divided into a main region and two edge regions. The main region is located in the middle, and the two edge regions are located on opposite sides of the main region.

[0085] The orthographic projection of the second support plate 120 onto the first support plate 110 at least partially covers the main body area. That is, the second support plate 120 is disposed opposite to the first support plate 110. The third support member 230 is disposed on the edge area of ​​the first support plate 110, that is, the third support member 230 is disposed on the first support plate 110 and is located in the edge area.

[0086] Since different models of battery devices may have different support requirements at the bottom edge of the lower housing, by setting a third support 230 in the edge area, additional support can be provided for the edge part of the battery device, improving the stability and uniformity of the support.

[0087] According to some embodiments of this application, please refer to Figures 3 to 5The main body area and two edge areas are arranged side by side along the second direction y. Each edge area is provided with multiple third support members 230, which are arranged at intervals along the first direction x.

[0088] The main body region and two edge regions are arranged side-by-side along the second direction y, with the main body region located in the middle and the two edge regions located on either side of the main body region along the second direction y. In each edge region, multiple third support members 230 are arranged at intervals along the first direction x, forming multiple support points arranged along the first direction x. In some examples, the third support members 230 can be used as locking points to support the housing.

[0089] Thus, the third support member 230 can provide multiple support points distributed along the first direction x at the edge position of the bottom of the battery device, which together with the first support member 210 and the second support member 220 in the main body area form a complete support system, which is conducive to further increasing the supported area of ​​the battery device, so that the battery device can be stably and uniformly supported on the support device 10.

[0090] According to some embodiments of this application, please refer to Figures 3 to 5 The third support member 230 includes a first step portion 231 and a second step portion 232, with the first step portion 231 located on the side of the second step portion 232 closer to the main body area. The height difference between the first step portion 231 and the reference surface 101 is smaller than the height difference between the second step portion 232 and the reference surface 101.

[0091] The third support member 230 adopts a stepped structure, including a first stepped portion 231 and a second stepped portion 232 with different heights. The first stepped portion 231 is closer to the main body area and has a lower height, while the second stepped portion 232 is farther away from the main body area and has a higher height.

[0092] Thus, this stepped structure can be adapted to the stepped structure at the bottom edge of the battery pack, allowing the third support 230 to fit better against the bottom of the battery pack, further increasing the supported area of ​​the battery pack, thereby helping to reduce stress concentration.

[0093] According to some embodiments of this application, please refer to Figure 6 and Figure 7 The support 200, which can be adjusted in height relative to the reference plane 101, is an adjustable support 260. The adjustable support 260 includes a plurality of support blocks 261, which are stacked sequentially along the direction perpendicular to the reference plane 101. The adjustable support 260 is configured to adjust the height of its support surface 201 relative to the reference plane 101 by increasing or decreasing the number of support blocks 261.

[0094] The adjustable support 260 includes a plurality of support blocks 261, for example, two, three, four or more, each support block 261 having a predetermined thickness. When it is necessary to increase the height of the support surface 201, the number of support blocks 261 is increased; when it is necessary to decrease the height of the support surface 201, the number of support blocks 261 is decreased.

[0095] The support block 261 can be made of metal, plastic, or other materials. The support blocks 261 can be detachably connected via positioning pins, snap-fit ​​fasteners, or other fastening components to reduce shifting during use. When the support block 261 is made of metal, it can also be connected magnetically.

[0096] This embodiment provides a height adjustment method that is simple in structure, low in cost, and structurally stable.

[0097] According to some embodiments of this application, please refer to Figure 5 The areas of the support surfaces of at least two support members 200 are different, and / or the profiles of the support surfaces of at least two support members 200 are different.

[0098] At least two support members 200 may have support surfaces 201 with different areas and / or different profiles; the support areas or profiles of some support surfaces 201 of the support members 200 may be different, or the support areas or profiles of all support surfaces 201 of the support members 200 may be different.

[0099] For example, a support member 200 with a larger area can be provided for a support position that needs to withstand a large load; a support member 200 with a specific contour shape can be provided for a support position that needs to avoid a specific structure at the bottom of the battery device.

[0100] At least two support members 200 have different profile shapes for their support surfaces, which can be rectangular, rhomboid, circular, elongated, or other shapes.

[0101] Thus, by making the support surfaces 201 of each support member 200 have different areas and / or shapes, the support surfaces 201 of the support device 10 are more adapted to the bottom structure of the battery device, which helps to increase the support area of ​​the battery device, thereby helping to reduce deformation or stress concentration caused by improper support.

[0102] This application also provides a battery production line, which includes the support device 10 provided in any of the foregoing embodiments. The specific structure of the support device 10 is as described in the above embodiments. Since this battery production line adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.
