[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 A restraint assembly 100 according to an embodiment of the first aspect of the present invention is described.

[0028] like Figures 1-3 As shown, the restraint assembly 100 according to a first aspect embodiment of the present invention includes a base 1 and an anti-tilt mechanism 2.

[0029] Specifically, the anti-tilt mechanism 2 is mounted on the base 1. The anti-tilt mechanism 2 includes a first restraint plate 21 and a second restraint plate 22. The first restraint plate 21 and the second restraint plate 22 are arranged along a first direction, and the first restraint plate and the second restraint plate 22 are arranged relative to the base 1 along a second direction (e.g., ...). Figure 1 The first restraint plate 21 is movable in the left and right directions, and the second restraint plate 22 is movable relative to the first restraint plate 21. The first and second directions intersect.

[0030] For example, in Figure 1In the example, the anti-tilt mechanism 2 is located on one side of the base 1 in the thickness direction. The shapes of the first restraint plate 21 and the second restraint plate 22 can be the same or different. The first direction can be understood as... Figure 1 The vertical or front-back direction is shown. That is, when the first restraint plate 21 and the second restraint plate 22 are arranged vertically, the first restraint plate 21 and the second restraint plate 22 can act together on the battery module 400 in the vertical direction to provide a dual force to the battery module 400, effectively preventing the battery module 400 from tilting significantly during restraint. When the first restraint plate 21 and the second restraint plate 22 are arranged front-back, the first restraint plate 21 and the second restraint plate 22 can act together on the battery module 400 in the vertical direction (e.g., Figure 4 The diagram shows a battery module 400 subjected to dual forces. Specifically, one side of the battery module 400, which runs parallel to the length of the base 1, is subjected to forces from two different locations to prevent the battery module 400 from tilting in the front-to-back direction. It should be noted that in the following description of this application, the first direction is referred to as... Figure 1 The vertical direction in the diagram is used as an example for illustration. Of course, the first and second directions are not limited to the perpendicular relationship shown in the diagram; other intersecting positional relationships are also within the scope of this application.

[0031] Reference Figure 1 and Figure 8 When the restraint assembly 100 acts on the battery module 400, the battery module 400 is located on the side where the first restraint plate 21 of the restraint assembly 100 is located. The first restraint plate 21 and the second restraint plate 22 are in contact with the battery module 400. Simultaneously, the first restraint plate 21 and the second restraint plate 22 can move left and right respectively to clamp the battery module 400 or separate from it. Therefore, the movement of the first restraint plate 21 and the second restraint plate 22 can be adjusted according to the actual production process to adjust the restraint force between the first restraint plate 21 and the second restraint plate 22 and the battery module 400. This facilitates more convenient and accurate restraint of the battery module 400, while also facilitating the control of the restraint assembly 100 and improving operational precision. Furthermore... The first restraint plate 21 and the second restraint plate 22 work together on the battery module 400, increasing the number of force-bearing points on the battery module 400 and making the force on the battery module 400 more balanced, which is more conducive to the smooth assembly and processing of the battery module 400.

[0032] For example, in Figures 1-3 In the example, the first restraint plate 21 and the second restraint plate 22 can be synchronously positioned relative to the base 1 along a second direction (e.g., Figure 1 The second restraint plate 22 is movable in the left and right directions. At the same time, the second restraint plate 22 and the first restraint plate 21 are relatively independent, and the second restraint plate 22 is movable in the second direction relative to the first restraint plate 21.

[0033] During the use of the restraint assembly 100, after the battery module 400 is placed, the first restraint plate 21 and the second restraint plate 22 can be driven to move simultaneously along the second direction toward the side where the battery module 400 is located, so as to cooperate with the other restraint assembly 100 to clamp the battery module 400. After the first restraint plate 21 stops moving, the battery module 400 can be further fine-tuned by adjusting the second restraint plate 22 individually, so that the battery module 400 is neatly arranged and does not tilt, and the anti-tilt mechanism 2 has a better anti-tilt effect. In addition, the moving directions of the first restraint plate 21 and the second restraint plate 22 can be the same as described above, or they can be different. For example, there can be a certain angle between the moving directions of the first restraint plate 21 and the moving directions of the second restraint plate 22, which can also achieve restraint of the battery module 400 and prevent tilting.

[0034] According to the first aspect of the present invention, the restraint assembly 100, by arranging a first restraint plate 21 and a second restraint plate 22 along a first direction, allows the first restraint plate 21 and the second restraint plate 22 to act together on the battery module 400 along the first direction, providing a dual (two force-bearing positions) force to the battery module 400, effectively preventing the battery module 400 from tilting significantly during restraint. Furthermore, after the first restraint plate 21 stops moving, the battery module 400 can be further fine-tuned by adjusting the second restraint plate 22 individually, ensuring that the battery module 400 is neatly arranged and does not tilt, effectively improving the anti-tilt effect of the anti-tilt mechanism 2.

[0035] According to some optional embodiments of the present invention, the first restraint plate 21 and the second restraint plate 22 can move independently of each other relative to the base 1 along a second direction. That is, the first restraint plate 21 and the second restraint plate 22 can be driven to move by different driving components. This reduces interference between the first restraint plate 21 and the second restraint plate 22, and also allows for independent adjustment of the first restraint plate 21 and the second restraint plate 22, resulting in more precise control and improved performance of the restraint assembly 100.

[0036] According to some embodiments of the present invention, with reference to Figures 1-3 The anti-tilt mechanism 2 includes a first moving mechanism 24 and a mounting plate 23. The first moving mechanism 24 is mounted on the base 1. The mounting plate 23 cooperates with the first moving mechanism 24 so as to be driven by the first moving mechanism 24 to move relative to the base 1 in a second direction. The first restraint plate 21 is mounted on the mounting plate 23 and can move with the mounting plate 23. The second restraint plate 22 is movably mounted on the mounting plate 23 in the second direction.

[0037] Specifically, refer to Figures 1-3The anti-tilt mechanism 2 further includes a mounting plate 23, which is movably disposed on the base 1 along the second direction. A first restraint plate 21 is disposed on the mounting plate 23 and is movable with the mounting plate 23. A second restraint plate 22 is movably disposed on the mounting plate 23 along the second direction.

[0038] For example, in Figures 1-3 In the example, the mounting plate 23 is movably positioned above the base 1, which can be configured as a rectangular plate structure. The mounting plate 23 is movable along the width direction of the base 1. The first restraint plate 21 and the second restraint plate 22 can move synchronously with the mounting plate 23. Simultaneously, the second restraint plate 22 is movable relative to the mounting plate 23 and the first restraint plate 21 along a second direction toward the side closer to and away from the battery module 400. Therefore, the overall structure and movement of the anti-tilt mechanism 2 are simpler. That is, the battery module 400 can be initially adjusted by synchronously adjusting the first restraint plate 21 and the second restraint plate 22. After the mounting plate 23 stops moving the first restraint plate 21, the second restraint plate 22 can move independently relative to the mounting plate 23 to further adjust the force exerted by the second restraint plate 22 on the battery module 400. In addition, the mounting plate 23 can be used to support and install the first restraint plate 21 and the second restraint plate 22, so as to make the movement of the first restraint plate 21 and the second restraint plate 22 more stable and improve the long-term stability of the first restraint plate 21 and the second restraint plate 22.

[0039] According to some embodiments of the present invention, with reference to Figures 1-3 The anti-tilt mechanism 2 further includes: a first moving mechanism 24, which is disposed on the base 1 and cooperates with the mounting plate 23 to drive the mounting plate 23 to move relative to the base 1 in a second direction.

[0040] For example, in Figures 1-3 In the example, the first moving mechanism 24 is located on the side of the mounting plate 23 away from the battery module 400, or in other words, the mounting plate 23 is located on one side of the base 1 in the width direction. The first moving mechanism 24 and the mounting plate 23 are arranged along the second direction, with the first moving mechanism 24 extending towards the other side of the base 1. This arrangement, through the cooperation of the first moving mechanism 24 and the mounting plate 23, converts power transmission into directional movement, avoiding deviations in the direction of movement and ensuring the accuracy of the mounting plate 23's movement. Furthermore, this connection method (such as the rigid cooperation between the mounting plate 23 and the first moving mechanism 24) can improve the overall structural load-bearing capacity, ensuring stable movement of the mounting plate 23 when connected to the first restraint plate 21 and the second restraint plate 22.

[0041] Optionally, the first moving mechanism 24 is a screw jack, which makes the first moving mechanism 24 more convenient to use and more conducive to the movement of the first restraint plate 21 and the second restraint plate 22. Of course, a cylinder, electric cylinder, motor screw assembly, or other driving power form can also be used.

[0042] According to some embodiments of the present invention, with reference to Figures 1-3 The first moving mechanism 24 includes a first driving device 241 and a restraining connecting rod 242. The first driving device 241 is mounted on the base 1. One end of the restraining connecting rod 242 is connected to the first driving device 241, and the other end of the restraining connecting rod 242 is engaged with the mounting plate 23. When the first driving device 241 is working, the first driving device 241 drives the restraining connecting rod 242 to move the mounting plate 23 relative to the base 1 in the second direction.

[0043] For example, in Figures 1-3 In the example, the mounting plate 23 is provided with a restraining connecting flange 231. The restraining connecting flange 231 can be located on the side of the mounting plate 23 away from the battery module 400 in the thickness direction. The first driving device 241 and the restraining connecting rod 242 are arranged along the second direction. That is, the arrangement along the second direction is as follows: first restraining plate 21, mounting plate 23, restraining connecting flange 231, restraining connecting rod 242 and first driving device 241. When the first driving device 241 is working, the first driving device 241 drives the restraining connecting rod 242 to move toward the side where the battery module 400 is located, so as to act on the mounting plate 23 through the restraining connecting flange 231, thereby driving the mounting plate 23 to move relative to the base 1 in the second direction. At the same time, the mounting plate 23 drives the first restraining plate 21 and the second restraining plate 22 to move. Of course, this application uses the example of the restraint connecting rod 242 being connected to the mounting plate 23 via the restraint flange 231 for illustration. The other end of the restraint connecting rod 242 can be directly connected and mated with the mounting plate 23.

[0044] With this configuration, the first drive device 241 is fixed to ensure stable power, the restraint connecting rod 242 controls the direction of movement, and the restraint connecting flange 231 optimizes the connection rigidity and adaptability. Ultimately, this achieves a comprehensive effect of precise power transmission, controllable direction of movement, strong structural load-bearing capacity, and convenient maintenance, thereby improving the movement accuracy, stability, and reliability of the restraint assembly 100 and further enhancing the performance of the restraint assembly 100.

[0045] According to some embodiments of the present invention, with reference to Figure 2 The restraint assembly 100 further includes a pressure sensor 3, which is disposed between the restraint connecting rod 242 and the mounting plate 23.

[0046] When the restraint assembly 100 is engaged with the battery module 400, the restraint pressure sensor 3 can accurately read the restraint force at both ends of the single module. The information read by the pressure sensor 3 can be transmitted to the control board (not shown in the figure). The control board can adjust the driving force of the first driving device 241, so as to control the force exerted on the battery module 400 by the first restraint plate 21 and the second restraint plate 22 by adjusting the moving distance of the mounting plate 23, thereby effectively controlling the restraint force of the battery module 400 and achieving precise process restraint monitoring. This is more conducive to the control of the restraint assembly 100 and the assembly process of the battery module 400.

[0047] According to some embodiments of the present invention, with reference to Figures 1-3 The restraint assembly 100 further includes a mounting base 4, which is disposed on the base 1, and a first moving mechanism 24 is disposed on the mounting base 4.

[0048] For example, in Figures 1-3 In the example, the mounting base 4 is disposed on the base 1 and extends along a first direction. The mounting base 4 can be positioned at the center of the base 1. The first driving device 241 and the restraint connecting rod 242 are respectively connected to both sides of the mounting base 4 along a second direction. The first driving device 241 is connected to the restraint connecting flange 231 through the restraint connecting rod 242. Thus, the mounting base 4 can be used to support, install, and fix the first moving mechanism 24, thereby making the connection between the first moving mechanism 24 and the mounting base 4 and the mounting plate 23 more stable. This is beneficial for the long-term stable use of the first moving mechanism 24 and extends the service life of the restraint assembly 100.

[0049] According to some embodiments of the present invention, with reference to Figure 1 The mounting base 4 is equipped with a distance measuring sensor 41.

[0050] For example, in Figure 1 In the example, a distance sensor 41 is provided on the side of the mounting base 4 facing the battery module 400 along the second direction. The distance sensor 41 can be used to accurately measure the dimension of the battery module 400 along the second direction that cooperates with the constraint assembly. For example, a single distance sensor 41 can measure the length of a single module along the second direction. Specifically, the distance sensor 41 can measure the distance value to the battery module 400 (e.g., a blade battery), and through conversion, the length (along the second direction) of the battery module 400 can be accurately calculated. It can also measure the dimensional values ​​of the battery module 400 before and after constraint, and by comparing with the standard values ​​required by the process, it can identify battery modules 400 with poor constraint, thereby achieving quality control of the processing.

[0051] Specifically, refer to Figure 1 The mounting base 4 is provided with a distance measuring plate 42, which is positioned along a third direction (e.g., Figure 1 Extending in the front-back direction, the ranging plate 42 is provided with at least one ranging sensor 41, and the first direction, the second direction, and the third direction are orthogonal. There can be multiple ranging sensors 41, which are arranged at intervals along the third direction. In the description of this invention, "multiple" means two or more.

[0052] For example, in Figure 1 In the example, the base 1 extends along a third direction, the distance measuring plate 42 is connected to the end of the mounting base 4 away from the base 1, the distance measuring plate 42 is located between the mounting base 4 and the mounting plate 23, the mounting plate 23 and the first restraint plate 21 are respectively formed with perforations 211, the distance measuring sensor 41 is opposite to the perforations 211 to improve the measurement accuracy of the distance measuring sensor 41. Figure 1 The example shows two ranging sensors 41, which can measure the length of the two sides of the battery module 400 in the width direction, thereby improving the measurement accuracy of the length dimension of the battery module 400. This is more conducive to the identification of poorly constrained battery modules 400 and to the quality control of the processing process.

[0053] According to some embodiments of the present invention, with reference to Figures 1-3 The ranging plate 42 is provided with two ranging mounting plates 43 symmetrically arranged along the third direction, and multiple ranging sensors 41 are respectively mounted on the two ranging mounting plates 43.

[0054] For example, in Figures 1-3 In the example, there are two ranging mounting plates 43 and two ranging sensors 41, with each pair corresponding to a different ranging sensor 41. That is, two ranging mounting plates 43 are connected to the ranging plate 42, and each ranging mounting plate 43 is connected to a ranging sensor 41. Therefore, the ranging mounting plates 43 can be used to install and fix the ranging sensors 41, increasing the installation area between the ranging sensors 41 and the ranging plate 42, making the installation and fixation of the ranging sensors 41 more secure, which is beneficial for the long-term stable use of the ranging sensors 41.

[0055] like Figures 1-3 As shown, the ranging mounting plate 43 is movable relative to the ranging plate 42 in a third direction. That is, the ranging mounting plate 43 can be adjusted on the ranging plate 42 according to the size of the battery module 400, so as to make the measurement of multiple ranging sensors 41 more accurate.

[0056] According to some embodiments of the present invention, with reference to Figures 1-3 The first restraint plate 21 is provided on one side of the mounting plate 23 along the second direction.

[0057] For example, in Figures 1-3In the example, the first restraint plate 21 is connected to one side of the mounting plate 23 along its thickness direction, and the first restraint plate 21 is located on the side of the mounting plate 23 facing the battery module 400. This arrangement provides two advantages: firstly, a larger contact area between the first restraint plate 21 and the mounting plate 23, improving the stability of the first restraint plate 21 during installation; secondly, the reasonable layout of the components of the restraint assembly 100 facilitates contact between the first restraint plate 21 and the battery module 400 without interfering with the use of other components such as the first moving mechanism 24. This results in a less compact arrangement of the components of the restraint assembly 100, making it convenient to use and resulting in a more sophisticated overall structure.

[0058] According to some embodiments of the present invention, with reference to Figure 3 The anti-tilt mechanism 2 further includes a second moving mechanism 25, which is disposed on the mounting plate 23 and cooperates with the second restraint plate 22 to drive the second restraint plate 22 to move in a second direction. And / or, at least one guide rail seat 5, which is disposed on the base 1, and the mounting plate 23 is movable relative to the guide rail seat 5 in a second direction.

[0059] For example, in Figure 3 In the example, both the second moving mechanism 25 and the second restraint plate 22 are mounted on the mounting plate 23, allowing the first moving mechanism 24 to simultaneously drive multiple components, including the second moving mechanism 25, the mounting plate 23, and the second restraint plate 22, thereby achieving synchronous control of the first restraint plate 21 and the second restraint plate 22. This reduces the difficulty of controlling the first restraint plate 21 and the second restraint plate 22 and improves the accuracy of their synchronous movement. Furthermore, by having the second moving mechanism 25 independently drive the second restraint plate 22, individual adjustment of the second restraint plate 22 is achieved, thus improving the restraint accuracy of the restraint assembly 100, and ensuring that the first moving mechanism 24 and the second moving mechanism 25 do not interfere with each other. For example, the second moving mechanism 25 could be a cylinder; alternatively, an electric cylinder, a motor screw assembly, or other driving power source could be used.

[0060] According to other embodiments of the present invention, refer to Figures 1-3 The restraint assembly 100 further includes at least one guide rail seat 5, which is disposed on the base 1, and the mounting plate 23 is movable relative to the guide rail seat 5 in a second direction.

[0061] For example, in Figures 1-3 In the example, the guide rail 5 and the mounting base 4 are arranged along a third direction, and the mounting plate 23 is located at one end of the guide rail 5 along a second direction. Thus, the guide rail 5 guides the mounting plate 23, making the movement of the mounting plate 23 in the second direction more accurate and reducing movement deviation, thereby further ensuring the accuracy of the restraint of the second restraint plate 22 and the first restraint plate 21 of the restraint assembly 100.

[0062] Optionally, combined Figures 1-3 Two guide rail seats 5 are provided, located on opposite sides of the mounting base 4 along a third direction. The two mounting bases 4 can be close to or far apart from each other. Each guide rail seat 5 has a linear guide rail 53. A push rod 232 is connected to the side of the mounting plate 23 away from the first restraint plate 21. The linear guide rail 53 extends along a second direction, and the push rod 232 is movably fitted onto the linear guide rail 53. Thus, through the cooperation of the linear guide rail 53 and the push rod 232, the guide rail seat 5 guides the movement of the mounting plate 23, and the movement of the push rod 232 is also stable. In addition, one end of the length direction of the two push rods 232 is connected to both ends of the mounting plate 23 along a third direction, that is, the middle of the mounting plate 23 is connected to the restraint connecting flange 231, and the two sides along the length direction are connected to the aforementioned ends of the two push rods 232, making the connection of the mounting plate 23 more stable and improving the stability of use and movement. Alternatively, the linear guide 53 and the push rod 232 can be replaced with sliding components consisting of a guide shaft 221 and a linear bearing.

[0063] According to some embodiments of the present invention, with reference to Figure 3 The anti-tilt mechanism 2 further includes a guide device 26, which is disposed on the mounting plate 23. The second moving mechanism 25 is disposed on the guide device 26. A guide hole 261 is formed on one of the guide device 26 and the second restraint plate 22. A guide shaft 221 is provided on the other of the guide device 26 and the second restraint plate 22. The guide shaft 221 is movable relative to the guide hole 261 along a second direction.

[0064] For example, in Figure 3 In the example, the second restraint plate 22 is provided with two guide shafts 221, and the guide device 26 is formed with two guide holes 261, with the two guide shafts 221 respectively engaging within the two guide holes 261. With this configuration, when the second moving mechanism 25 drives the second restraint plate 22 to move relative to the mounting plate 23, the engagement of the guide shafts 221 and the guide holes 261 ensures the accuracy of the movement of the second restraint plate 22, allowing it to move smoothly in the second direction. Furthermore, the engagement of the two guide shafts 221 and the two guide holes 261 also makes the guidance of the guide device 26 more accurate. In addition, the guide device 26 also stably connects the second restraint plate 22 and the second moving mechanism 25 to the mounting plate 23.

[0065] According to some optional embodiments of the present invention, refer to Figure 3A guide connecting plate 222 is provided between the second restraint plate 22 and the guide device 26. The second restraint plate 22 is connected to one side of the guide connecting plate 222, and the guide shaft 221 can be provided on the guide connecting plate 222. Thus, the guide connecting plate 222 can serve as a transitional connecting component between the second restraint plate 22 and the guide device 26, ensuring stable connection of the second restraint plate 22 and stable movement of the second restraint plate 22.

[0066] According to some embodiments of the present invention, with reference to Figure 3 The guide device 26 is located on one side of the mounting plate 23 adjacent to the base 1. The second restraint plate 22 is located on one side of the guide device 26 along the second direction. The second moving mechanism 25 is located on the other side of the guide device 26 along the second direction. A guide hole 261 is formed on one of the guide device 26 and the second restraint plate 22, and a guide shaft 221 is provided on the other of the guide device 26 and the second restraint plate 22. The guide shaft 221 is movable relative to the guide hole 261 along the second direction. For example, in Figure 3 In the example, the guide device 26 is connected to the bottom of the mounting plate 23, and the second restraint plate 22 and the second moving device are respectively located on both sides of the guide device 26 along the second direction. This arrangement results in a reasonable layout between the guide device 26, the mounting plate 23, the second restraint plate 22, and the second moving mechanism 25, which facilitates the use of each component and also makes the restraint assembly 100 more concise overall.

[0067] According to some embodiments of the present invention, with reference to Figures 1-3 The base 1 has at least one set of base adjustment holes 11, which includes multiple base adjustment holes 111. These multiple base adjustment holes 111 are spaced apart along a third direction. The guide rail seat 5 engages with any one of the multiple base adjustment holes 111 to adjust the position of the guide rail seat 5 relative to the base 1 in a third direction. The first direction, the second direction, and the third direction are orthogonal. And / or, the guide rail seat 5 has at least one second guide rail seat adjustment hole 52, which extends along a second direction.

[0068] For example, in Figures 1-3In the example, the guide rail 5 extends along the second direction, and multiple base adjustment holes 111 extend along the third direction. Therefore, by providing multiple base adjustment holes 111, the guide rail 5 can be fixed at any position along the third direction of the base 1 by engaging any one of the multiple base adjustment holes 111. This facilitates adjusting the position of the guide rail 5 according to the size of the battery module 400, improving the applicability of the restraint assembly 100. Furthermore, the simple adjustment method simplifies the structure of the base 1, thereby simplifying the structure of the restraint assembly 100 and reducing manufacturing difficulty. It should be noted that the number and shape of the base adjustment holes 111 can be adjusted according to actual usage to better meet practical applications.

[0069] According to some embodiments of the present invention, with reference to Figure 2 At least one second guide rail adjustment hole 52 is formed on the guide rail seat 5, and the second guide rail adjustment hole 52 extends along the second direction.

[0070] For example, in Figure 2 In the example, the guide rail seat 5 has an L-shaped structure. A plurality of second guide rail seat adjustment holes 52 are provided on the portion of the guide rail seat 5 away from the base 1. These second guide rail seat adjustment holes 52 are spaced apart along a second direction. A plurality of first guide rail seat adjustment holes 51 are formed on the portion of the guide rail seat 5 that contacts the base 1. When the restraint assembly 100 is used for the battery module 400, the battery module 400 is secured to the support assembly 200. The support rod 201 of the support assembly 200 can be connected to the support rod 201 through the second guide rail seat adjustment holes 52, so that the support assembly 200 and the restraint assembly 100 are assembled as a whole. Furthermore, the second guide rail seat adjustment holes 52 extend along the second direction, and multiple fasteners can be fitted into the same second guide rail seat adjustment hole 52 to make the connection between the support rod 201 and the guide rail seat 5 more stable.

[0071] According to some embodiments of the present invention, with reference to Figures 1-3 At least one first guide rail adjustment hole 51 is formed on the guide rail base 5. The first guide rail adjustment hole 51 extends in a third direction and is matched with any one of the plurality of base adjustment holes 111. For example, in Figures 1-3 In the example, the first guide rail adjustment hole 51 extends through the bottom surface of the guide rail seat 5 along the first direction. Thus, the connecting member 7, such as a bolt, can be inserted through the first guide rail adjustment hole 51 and the corresponding base adjustment hole 111 to fix the guide rail seat 5 on the base 1. The installation and fixing are simple, and the disassembly is convenient, making it easy to adjust the position of the guide rail seat 5 on the base 1.

[0072] Furthermore, when the support assembly 200 cooperates with the restraint assembly 100, the two support rods 201 of the support assembly 200 can be connected to the two guide rail seats 5 respectively. During the adjustment of the position of the guide rail seat 5, which is equivalent to the base 1, the two support rods 201 can move closer or further apart. Thus, by adjusting the spacing of the support rods 201 of the support assembly 200 with both smaller and larger adjustments, it is theoretically possible to achieve arbitrary spacing adjustment. During the adjustment process, the first guide rail seat adjustment hole 51 and the base adjustment hole 111 are tightly engaged to ensure adjustment accuracy and achieve compatibility with battery modules 400 of different widths.

[0073] Optionally, the first guide rail adjustment hole 51 can be configured as an oblong hole to facilitate the fitting of the connector 7 within the first guide rail adjustment hole 51. The first guide rail adjustment hole 51 extends along a third direction, thereby facilitating fine-tuning of the fixed position of the guide rail 5, resulting in higher movement accuracy of the guide rail 5. It can be fixed at different positions on the base 1 to accommodate battery modules 400 of various sizes and specifications.

[0074] According to some embodiments of the present invention, with reference to Figures 1-3 The base adjustment hole group 11 consists of multiple groups, which are arranged at intervals along the second direction. The first guide rail seat adjustment hole 51 consists of multiple groups, which are arranged at intervals along the second direction, and are respectively opposite to the multiple groups of base adjustment hole groups 11.

[0075] For example, in Figures 1-3 In the example, Figure 2 The diagram shows four first guide rail seat adjustment holes 51, which are arranged at intervals along the second direction. The base adjustment hole group 11 has four sets, and the four sets of base adjustment hole groups 11 can respectively cooperate with the four first guide rail seat adjustment holes 51 to increase the fixing point between the guide rail seat 5 and the base 1, improve the installation stability of the guide rail seat 5, and thus ensure the stability of the restraint assembly 100 in use.

[0076] According to some embodiments of the present invention, referring to the figures, the bottom of the guide rail base 5 is provided with a guide member 54, which extends along the length direction of the base 1. A guide groove 13 is formed on the base 1, and the guide member 54 is fitted into the guide groove 13. Thus, the cooperation between the guide groove 13 and the guide member 54 makes it easier for the guide rail base 5 to move on the base 1, and ensures the accuracy of the movement direction.

[0077] According to some embodiments of the present invention, with reference to Figure 1 The restraint assembly 100 further includes at least one slider 12 disposed at the bottom of the base 1 and extending along a second direction. And / or, at least one power source 6 disposed on the base 1.

[0078] For example, in Figure 1 In the example, slider 12 is connected to the bottom surface of base 1, and a groove 121 is formed on slider 12, extending along a second direction. When restraint assembly 100 is used in restraint device, restraint assembly 100 can cooperate with other components through the groove 121 on slider 12, so that restraint assembly 100 can be movable relative to other components of restraint device, which is beneficial for transferring battery module 400 to the next process, and is more conducive to the assembly and processing of battery module 400.

[0079] According to some embodiments of the present invention, with reference to Figure 1 Slider 12 extends along the second direction. For example, in Figure 1 In the example, the slide 121 extends through both end faces of the second slide 121 along the second direction. This configuration facilitates the movement of the restraint assembly 100 along the second direction, ensuring accurate movement. Furthermore, the simple structure of the slide 12 makes manufacturing easier, further reducing the processing difficulty of the restraint assembly 100 and facilitating its integration with other components.

[0080] According to some embodiments of the present invention, with reference to Figure 1 The restraint assembly 100 further includes at least one power source 6, which is disposed on the base 1. Thus, the power source 6 can serve as a power source to drive the restraint assembly 100 to move in the second direction, thereby facilitating the overall movement of the restraint assembly 100.

[0081] According to some embodiments of the present invention, with reference to Figure 1 There are multiple power sources 6, each located at one end of the base 1 along a third direction, with the first, second, and third directions orthogonal to each other. For example, in... Figure 1 In the example, there are two power sources 6, located at opposite ends of the base 1 along a third direction. This arrangement allows the two power sources 6 to jointly drive the movement of the restraint assembly 100, enabling faster and more stable movement. Furthermore, the placement of the two power sources 6 away from the mounting base 4 and the anti-tilt mechanism 2 reduces interference between components, ensuring normal operation of all parts and minimizing space occupancy in the central area of ​​the restraint assembly 100. For example, the power source 6 may consist of a servo motor, a reducer, gears, etc., but is not limited to these components.

[0082] According to some embodiments of the present invention, the base 1 may be provided with a sliding groove (not shown in the figure), and a portion of the support rod 201 may be fitted into the sliding groove to realize the movement of the support rod 201 relative to the base 1 in a second direction. The support rod 201 can be fixed at any position on the base 1, thereby realizing stepless adjustment of the spacing of the support rod 201.

[0083] According to a second aspect of the present invention, a support assembly 200 for a battery module 400 is adapted to cooperate with a restraint assembly 100 according to the first aspect of the present invention.

[0084] According to a second aspect embodiment of the present invention, a support assembly 200 for a battery module 400, such as Figure 6 As shown, the support component 200 can be used to support the battery module 400. When the restraint component 100 is used with the battery module 400, the support component 200 and the restraint component 100 are connected to form a restraint device 300. The battery module 400 can be placed on the support component 200, and the restraint component 100 is used to restrain the battery module 400 so that the battery module 400 meets the requirements after assembly and during processing. In addition, by using the support component 200 in conjunction with the restraint component 100, the battery module 400 is less likely to tilt over a large area during restraint. At the same time, the support component 200 and the restraint component 100 are set separately, and more battery modules 400 of different sizes can be placed on the support component 200, improving the performance of the support component 200.

[0085] According to some embodiments of the present invention, with reference to Figure 1 and Figure 8 There are multiple restraint components 100, which are respectively disposed at both ends of the support component 200 along the second direction. The multiple restraint components 100 can move closer to or further away from each other relative to the support component 200 in the second direction. For example, in... Figure 1 and Figure 8 In the example, two restraint components 100 are provided, and the two restraint components 100 are respectively connected to both ends of the support component 200 along its length. Therefore, the support component 200 and the restraint components 100 have higher compatibility. The two restraint components 100 can move symmetrically along the second direction to meet the restraint requirements of battery modules 400 with different lengths, thereby further improving the applicability of the restraint components 100 and the support component 200 and enhancing their performance.

[0086] According to some embodiments of the present invention, with reference to Figure 1 and Figure 8 At least one of the multiple restraint components 100 is provided with a power source 6, which is adapted to drive the restraint component 100 and the support component 200 to move together in a second direction on the operating device. For example, in Figure 1 and Figure 8In the example, two restraint components 100 are provided, and one of the two restraint components 100 is equipped with a power source 6. Thus, the power source 6 can drive the two restraint components 100 and the support component 200 to move as a whole, thereby facilitating the assembly line operation of the battery module 400 and improving work efficiency. Furthermore, the restraint components 100 and the support component 200 have wider applications, and the presence of the power source 6 allows the present invention to be used as an independent component of the restraint device.

[0087] According to some embodiments of the present invention, with reference to Figure 5 The support assembly 200 includes at least one support rod 201 extending in a second direction, and the restraint assembly 100 is adapted to cooperate with the support rod 201.

[0088] For example, in Figure 5 In the example, when there are two restraint components 100, each restraint component 100 can be connected to one or both ends of the support rod 201 along the second direction. This arrangement has several advantages. First, the support rod 201 has a simple structure, making installation and disassembly of the support rod 201 and the restraint components 100 convenient. It also simplifies the structure of the support component 200, making its processing and use more convenient. Second, it facilitates the processing of the restrained battery module 400. The area between the two restraint components 100, except for the support component 200, is a clear area, which is beneficial for processing the upper and lower surfaces of the restrained battery module 400 (such as plasma cleaning, adhesive application, PP sheet bonding, UV curing, etc.). Furthermore, the arrangement of the support rod 201 ensures support for the battery module 400 while minimizing the contact area with the battery module 400, further facilitating its processing.

[0089] According to some embodiments of the present invention, with reference to Figure 5 At least one set of support rod adjustment holes 2011 is formed on the support rod 201. The support rod adjustment hole set 2011 includes a plurality of support rod adjustment holes 2012. The plurality of support rod adjustment holes 2012 are arranged at intervals along the second direction. The restraint assembly 100 is adapted to cooperate with any one of the plurality of support rod adjustment holes 2012 to adjust the position of the restraint assembly 100 relative to the support rod 201 in the second direction.

[0090] For example, in Figure 5In the example, multiple support rod adjustment holes 2012 are arranged at intervals along the length of the support rod 201. When the support rod 201 is connected to the restraint assembly 100, at least one of the multiple support rod adjustment holes 2012 is opposite to at least one second guide rail seat adjustment hole 52 on the guide rail seat 5, so that the support rod 201 and the guide rail seat 5 are connected by fasteners. Thus, the arrangement of multiple support rod adjustment holes 2012 is beneficial for the second guide rail seat adjustment hole 52 to cooperate with the support rod adjustment holes 2012 at different positions on the support rod 201, so that the restraint assembly 100 is fixed at different positions on the support rod 201, thereby adjusting the distance between the two restraint assemblies 100 to achieve the stable support requirements of battery modules 400 with different lengths. In addition, the support rod 201 has a simple structure, and the installation and disassembly of the support rod 201 and the restraint assembly 100 are also relatively simple, which is conducive to the cooperative use of the support rod 201 and the restraint assembly 100.

[0091] According to some embodiments of the present invention, with reference to Figure 5 There are multiple sets of support rod adjustment hole groups 2011, which are arranged at intervals along the second direction. There are multiple restraint components 100, which are respectively matched with the multiple sets of support rod adjustment hole groups 2011.

[0092] For example, in Figure 5 In the example, there are two sets of support rod adjustment hole groups 2011 and two sets of restraint components 100, with the two sets of support rod adjustment hole groups 2011 located near both ends of the support rod 201 along its length. Therefore, by setting multiple sets of support rod adjustment hole groups 2011, multiple restraint components 100 can be movably mounted on the support rod 201, and the position adjustment of the multiple restraint components 100 on the support rod 201 is simpler and more conducive to the cooperative use of the support rod 201 and the restraint components 100.

[0093] According to some embodiments of the present invention, with reference to Figure 5 The support rod 201 is provided with at least one adjusting plate 2013, which is adapted to cooperate with the guide rail seat 5 of the restraint assembly 100. And / or, the support rod 201 is provided with a positioning pin 2014, and the support assembly 200 further includes a partition beam 2015, which is detachably mounted on the positioning pin 2014.

[0094] For example, in Figure 5In the example, when the support rod 201 is connected to the guide rail seat 5, multiple support rod adjustment holes 2012 are respectively opposite to multiple second guide rail seat adjustment holes 52. Fasteners are inserted through the support rod adjustment holes 2012 and the second guide rail seat adjustment holes 52. The adjustment plate 2013 is connected to the end face of the guide rail seat 5 away from the support component 200. During the assembly process of the support rod 201 and the guide rail seat 5, the restraint component 100 can be pre-positioned by cooperating with the support rod adjustment holes 2012 and the second guide rail seat adjustment holes 52. Then, the position of the restraint component 100 can be more precisely fine-tuned by connecting the adjustment plate 2013 to the guide rail seat 5, thereby adjusting the distance between the two restraint components 100 by a small margin. That is, by adjusting the plate 2013 and the guide rail seat 5, the distance between the two restraint components 100 can be adjusted to a smaller extent. By adjusting the support rod adjustment holes 2012 at different positions, the distance between the two restraint components 100 can be adjusted to a larger extent. Through the dual adjustment of the distance between the two restraint components 100, both the smaller and larger ones, it is theoretically possible to be compatible with battery modules 400 of different lengths and sizes.

[0095] According to some embodiments of the present invention, with reference to Figure 5 The support rod 201 is equipped with a locating pin 2014. For example, in Figure 5 In the example, the positioning pin 2014 is provided on the upper surface of the support rod 201, and the positioning pin extends along the first direction toward the side away from the support rod 201. Only one positioning pin can be provided on the support rod 201 so that two sets of battery modules 400 can be placed on the support assembly 200, with the two sets of battery modules 400 located on both sides of the positioning pin, so that the restraint assembly 100 can act on both sets of battery modules 400 at the same time, thereby improving the restraint efficiency of the restraint assembly 100.

[0096] According to some embodiments of the present invention, with reference to Figure 9 The support assembly 200 further includes a partition beam 2015, which is adapted to be mounted on a positioning pin 2014. For example, a mating groove can be formed at the bottom of the partition beam 2015. The partition beam 2015 is detachably mounted on the support rod 201 through the mutual engagement of the positioning pin 2014 and the mating groove, thereby dividing the area above the support rod 201 into multiple areas. Multiple battery modules 400 can be placed in these multiple areas, facilitating quick assembly of the battery modules 400 with the support assembly 200. It should be noted that the partition beam 2015 can also be directly mounted on the battery modules 400, i.e., a partition beam 2015 is provided between two battery modules 400. When the battery modules 400 are mounted on the support rod 201, the partition beam 2015 engages with the positioning pin 2014. It should be noted that the thickness of the partition beam 2015 is designed according to the spacing requirements of the two battery modules 400.

[0097] According to some embodiments of the present invention, with reference to Figure 5 The positioning pin 2014 is detachably mounted on the support rod 201. And / or, the partition beam 2015 is detachably mounted on the positioning pin 2014.

[0098] Therefore, the detachable connection between the positioning pin 2014 and the support rod 201 facilitates the installation and replacement of the positioning pin 2014. It also allows the support rod 201 to select whether to install the positioning pin 2014 based on the number of battery modules 400 used in actual application, thereby improving the ease of use and applicability of the support assembly 200. For example, the bottom of the partition beam 2015 can have a mating groove. The positioning pin 2014 and the mating groove work together to mount the partition beam 2015 on the support rod 201, achieving compatibility with battery modules 400 of different structures. This facilitates the installation and disassembly of the partition beam 2015, further improving the performance of the support assembly 200.

[0099] According to some embodiments of the present invention, with reference to Figure 5 The top of the support rod 201 is provided with a pad 2016, which is a non-metallic material. For example, in Figure 5 In the example, the pad 2016 is connected to the upper surface of the support rod 201, and the pad 2016 extends along the second direction, with a length less than that of the support rod 201. With this configuration, when the battery module 400 is placed on the support rod 201, the bottom of the support module contacts at least a portion of the pad 2016, increasing the friction between the battery module 400 and the support rod 201. This makes it less likely for the battery module 400 to fall off the support rod 201, thereby improving the stability of the fit between the battery module 400 and the support assembly 200. Furthermore, the use of non-metallic materials facilitates contact between the battery module 400 and the pad 2016, preventing it from falling off and improving the installation stability of the battery module 400.

[0100] According to some embodiments of the present invention, with reference to Figure 5 There are multiple support rods 201, which are arranged at intervals along a third direction, with the second direction perpendicular to the third direction. For example, in... Figure 5In the example, the support scheme adopts a bridge-type double-beam structure design, with two support rods 201 arranged at intervals along a third direction. This configuration allows the two support rods 201 to jointly support the battery module 400, improving the stability of the connection between the battery module 400 and the support rods 201, and facilitating the stable use of the support assembly 200. The multiple support rods 201 have largely identical structures, and the same end of each support rod 201 can be connected to multiple guide rail seats 5 of the restraint assembly 100. By adjusting the relative distance between two guide rail seats 5, the distance between the two support rods 201 can be adjusted, allowing the support assembly 200 and the restraint assembly 100 to be adapted to battery modules 400 of different widths, thus achieving stable support for battery modules 400 of varying widths.

[0101] According to a third aspect embodiment of the present invention, the restraint device 300, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, it includes a restraint component 100 according to the first aspect embodiment described above, and / or a support component 200 for the battery module 400 according to the second aspect embodiment described above.

[0102] According to a third aspect embodiment of the present invention, the restraint device 300 includes the restraint component 100 or the support component 200 described above, or includes both the restraint component 100 and the support component 200. When the restraint device 300 includes both restraint components 100 and one support component 200, the battery module 400 can be fitted in the area between the two restraint components 100. At least one battery module 400 can be placed, or multiple battery modules 400 can be placed, and the multiple battery modules 400 are arranged along the second direction.

[0103] This configuration enhances the compatibility of the restraint device 300. The two restraint components 100 can move symmetrically along the second direction to accommodate battery modules 400 of varying lengths. Similarly, the two support rods 201 of the support component 200 can move symmetrically along the third direction to provide stable support for battery modules 400 of varying widths. Furthermore, it facilitates the processing of the restrained battery module 400. The area between the two restraint components 100, except for the support component 200, is a cleared area, allowing for surface processing of the restrained battery module 400 (such as plasma cleaning, adhesive application, PP sheet bonding, UV curing, etc.). Additionally, this invention employs dual-power restraint, meaning both ends are independently driven. This results in more even force distribution on both ends of the battery module 400 during restraint, and also increases restraint efficiency. With a partition beam 2015 in the middle of the support component 200, both battery modules 400 can be restrained simultaneously, doubling the restraint efficiency. Moreover, the present invention is designed with a pressure sensor 3 and a distance sensor 41. First, it can effectively control the restraint force of the battery module 400 and realize accurate process restraint monitoring. Second, it can measure the dimensional values ​​of the module before and after restraint, and by comparing them with the standard values ​​required by the process, it can identify battery modules 400 with poor restraint and realize quality control of the processing process.

[0104] According to the restraint device 300 of the present invention, during restraint, the pressure sensor 3 reads the restraint force at both ends of the single module, and after restraint, the distance sensor 41 measures the length dimension of the battery module 400 after restraint. After the restraint is qualified, the conveying mechanism moves the single module away, realizing a complete single module restraint action process. Figure 9 The present invention demonstrates a dual-module restraint embodiment. One battery module 400 is placed on the support assembly 200 with its side against the partition beam 2015, and the other battery module 400 is placed on the support assembly 200 with its other side against the partition beam 2015. The two restraint assemblies 100 simultaneously apply restraint forces along the second direction. During restraint, the pressure sensor 3 reads the restraint forces at both ends of the single module. After restraint, the distance sensor 41 measures the length of the battery module 400 after restraint. After the restraint is qualified, the transport mechanism moves both modules together, realizing a complete dual-module restraint operation process.

[0105] Furthermore, for the structure with a partition beam 2015 between the two battery modules 400, the partition beam 2015 is a component of the dual modules. The dual module restraint embodiment of the present invention should be as follows: the partition beam 2015 is placed in the middle of the support component 200, one battery module 400 is placed on the support component 200 with one side of the partition beam 2015 close to it, and the other battery module 400 is placed on the support component 200 with the other side of the partition beam 2015 close to it. The two restraint components 100 simultaneously apply restraint forces along the second direction. During restraint, the pressure sensor 3 reads the restraint forces at both ends of the single module. After the restraint is released, the distance sensor 41 measures the length of the battery module 400 after restraint. After the restraint is qualified, the conveying mechanism moves the dual modules (one battery module 400 + partition beam 2015 + the other battery module 400) together to realize a complete dual module restraint action process.
