[0003] Currently, deviations caused by battery module assembly into the battery box are difficult to repair. As battery modules composed of multiple cells are becoming increasingly larger, the difficulty of positioning and assembling them into the battery box also increases due to interference from the position of conductive foam and other accessories inside the battery box. Utility Model Content

[0004] The purpose of this utility model is to provide a guiding fixture that can guide the battery module to be positioned and installed into the battery box.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A guide fixture is provided, including a fixture assembly, the fixture assembly including a fixture body, the fixture body including a guide portion, the guide portion having a limiting surface and a guide surface connected to the top edge of the limiting surface;

[0007] The tooling assembly can be installed on the side plate of the battery box, and the limiting surface is located inside the side plate and can abut against the periphery of the battery module, and the guide surface protrudes from the top of the side plate.

[0008] Preferably, the tooling body further includes:

[0009] The middle part is connected to the guide part;

[0010] A connecting portion is connected to the middle portion, and a clearance groove is formed between the guide portion, the middle portion and the connecting portion, and the side plate can extend into the clearance groove.

[0011] Preferably, the connecting part is provided with a connecting hole, and the tooling assembly further includes a screw connector, which passes through the connecting hole and can clamp the side plate with the guide part, and the screw connector is threadedly connected to the connecting hole.

[0012] Preferably, the screw connector includes a threaded portion and a boss at a first end of the threaded portion. The end of the boss facing away from the threaded portion has a clamping surface that can clamp the side plate with the guide portion, and the area of ​​the clamping surface is larger than the cross-sectional area of ​​the threaded portion.

[0013] Preferably, the connecting part is provided with a sleeve on the side opposite to the guide part, the sleeve is coaxially arranged with the connecting hole, and the screwed member passes through the sleeve and is threadedly connected to the connecting hole.

[0037] Reference Figures 1 to 5 As shown, this embodiment provides a guiding fixture for the assembly of battery packs.

[0038] Specifically, the battery pack includes a battery box 100 and a battery module 200.

[0039] Specifically, the guide fixture includes a fixture assembly, the fixture assembly includes a fixture body 300, the fixture body 300 includes a guide portion 310, the guide portion 310 has a limiting surface 311 and a guide surface 312 connected to the top edge of the limiting surface 311.

[0040] In this embodiment, the tooling assembly can be installed on the side plate 110 of the battery box 100, and the limiting surface 311 is located inside the side plate 110 and can abut against the periphery of the battery module 200, while the guide surface 312 protrudes from the top of the side plate 110. The top of the limiting surface 311 refers to the end of the tooling assembly that is away from the bottom of the battery box 100 when it is installed on the side plate 110. The tops of other structures of the tooling assembly are defined in the same way as the top of the limiting surface 311, and will not be described further in this application. The top of the side plate 110 refers to the end of the side plate 110 that is away from the bottom of the battery box 100.

[0041] For example, when assembling the battery pack, after the tooling components are installed on the side plate 110 of the battery box 100, the battery module 200 is inserted into the battery box 100. Because the guide surface 312 protrudes from the top of the side plate 110, the battery module 200 first contacts the guide surface 312. Under the guidance of the guide surface 312, the battery module 200 will not collide with the side plate 110, effectively preventing damage to the battery module 200 and the battery box 100 due to collision. Furthermore, after the battery module 200 is inserted into the battery box 100, the periphery of the battery module 200 abuts against the limiting surface 311. Under the limiting of the limiting surface 311, the battery module 200 and the battery box 100 have good positioning accuracy, effectively avoiding rework due to positioning deviation between the battery module 200 and the battery box 100. The number of tooling components can be determined according to the actual size of the battery module 200.

[0042] Furthermore, the guide fixture is suitable for guiding battery modules 200 of different sizes into battery boxes 100 of corresponding sizes, exhibiting good compatibility. It is understood that the battery boxes 100 corresponding to different sizes of battery modules 200 will also have different dimensions, but the gap between the side plate 110 of the battery box 100, which can accommodate the fixture components, and the battery module 200 will be the same.

[0043] For example, the guide fixture may include multiple fixture components. That is, when assembling the battery pack, multiple fixture components can be installed at intervals on the side plate 110 of the battery box 100. The positioning accuracy between the battery module 200 and the battery box 100 is higher, and the rework situation caused by the positioning deviation between the battery module 200 and the battery box 100 is more effectively avoided.

[0044] For example, after the battery module 200 is installed into the battery box 100, the tooling assembly can be removed from the side plate 110 to enable the reuse of the tooling assembly.

[0045] For example, the guide surface 312 includes, but is not limited to, rounded or chamfered surfaces, to ensure that the battery module 200 can be smoothly installed into the battery box 100 via the guide surface 312 and to prevent the battery module 200 from bumping into the side panel 110.

[0046] In this embodiment, reference is made to Figures 1 to 3 As shown, the tooling body 300 also includes a middle part 320 and a connecting part 330. The middle part 320 is connected to the guide part 310, and the connecting part 330 is connected to the middle part 320. A clearance groove 301 is formed between the guide part 310, the middle part 320 and the connecting part 330. The side plate 110 can extend into the clearance groove 301. While ensuring that the battery module 200 will not collide with the side plate 110, the guide surface 312 protrudes from the top of the side plate 110 at a moderate height, resulting in a compact structure.

[0047] In some embodiments, the guide portion 310 and the connecting portion 330 can clamp the side plate 110 to fix the tooling body 300 onto the side plate 110.

[0048] In other embodiments, the connecting portion 330 is provided with a connecting hole, and the tooling assembly further includes a screw connector 400. The screw connector 400 passes through the connecting hole and can clamp the side plate 110 with the guide portion 310, and the screw connector 400 is threadedly connected to the connecting hole. In this embodiment, the tooling body 300 can be first fitted onto the side plate 110, and then the screw connector 400 can be screwed on to clamp the side plate 110 with the guide portion 310, which is stable, reliable, and easy to assemble.

[0049] For example, the connecting part 330 is provided with at least one connecting hole, such as two, to ensure that the tooling assembly is stably fixed to the side plate 110. The connecting holes are provided one-to-one with the screws 400.

[0050] Of course, the tooling components can also be installed on the side plate 110 by snap-fit ​​or other connection methods, which is not limited in this embodiment.

[0051] In some embodiments, the tooling body 300 may be a U-shaped structure composed of a guide portion 310, a middle portion 320, and a connecting portion 330; or the top of the guide portion 310 may protrude from the middle portion 320. In other embodiments, the tooling body 300 may not include the connecting portion 330, that is, the tooling body 300 may have an L-shaped or T-shaped structure, and the middle portion 320 of the tooling body 300 may be externally connected to a drive module, and the tooling body 300 may be driven by the drive module to overlap the side plate 110 of the battery box 100. Of course, the tooling body 300 may also be a structural component of other shapes, which is not limited in this embodiment.

[0052] In one feasible embodiment, the screw connector 400 includes a threaded portion 410 and a boss 420 provided at a first end of the threaded portion 410. The end of the boss 420 facing away from the threaded portion 410 has a clamping surface 421 capable of clamping the side plate 110 with the guide portion 310, and the area of ​​the clamping surface 421 is larger than the cross-sectional area of ​​the threaded portion 410. In this embodiment, the boss 420 increases the contact area between the screw connector 400 and the side plate 110, preventing the tooling assembly from sliding relative to the side plate 110 and ensuring a stable and reliable connection between the tooling assembly and the side plate 110.

[0053] For example, the boss 420 can be frustum-shaped for easy machining.

[0054] For example, the second end of the threaded portion 410 can be configured as an internal hexagonal structure.

[0055] In one feasible embodiment, a sleeve 331 is provided on the side of the connecting portion 330 opposite to the guide portion 310. The sleeve 331 is coaxially arranged with the connecting hole, and the screw connector 400 passes through the sleeve 331 and is threadedly connected to the connecting hole. In this embodiment, the sleeve 331 can limit the screw connector 400 to prevent the screw connector 400 from deflecting when connected to the connecting hole, ensuring that the clamping surface 421 and the side plate 110 are stably fitted, thereby enabling the screw connector 400 and the guide portion 310 to stably clamp the side plate 110, effectively preventing the tooling assembly from sliding relative to the side plate 110.

[0056] In this embodiment, reference continues to be made to... Figures 1 to 3As shown, the tooling assembly also includes an elastic pad 500, which is disposed on the side of the guide portion 310 opposite to the limiting surface 311. When the tooling assembly is installed on the side plate 110 of the battery box 100, the elastic pad 500 can be sandwiched between the guide portion 310 and the side plate 110. When the battery module 200 is inserted into the battery box 100, the elastic pad 500 can buffer the impact of the battery module 200 on the battery box 100 caused by the insertion deviation through the tooling body 300, effectively preventing damage to the battery module 200 and the battery box 100. In this embodiment, the thickness of the elastic pad 500 can be set according to the allowable positional tolerance of the battery module 200 inserted into the battery box 100.

[0057] For example, the guide portion 310 clamps the side plate 110 with the connecting portion 330 or the screw connector 400 via the elastic pad 500.

[0058] For example, the elastic pad 500 can be adhered to the guide portion 310.

[0059] For example, the elastic pad 500 can be made of foam, which has good elasticity and can adapt to different pressure changes, making it convenient for tooling components to be assembled on the side plate 110, and can provide good cushioning for the impact on the battery box 100 when the battery module 200 is installed.

[0060] Specifically, the guide portion 310 also has a fixing surface 313 disposed opposite to the limiting surface 311. The fixing surface 313 is in contact with the elastic pad 500 so that the elastic pad 500 can be stably fixed on the guide portion 310.

[0061] For example, the fixing surface 313 and the limiting surface 311 are parallel to each other.

[0062] In this embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 As shown, the battery module 200 includes multiple rows of battery cells 210, with each row including at least one battery cell 210. The battery cells 210 can be arranged in a matrix.

[0063] In this embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the side plate 110 includes two long side plates 111 spaced apart along the width direction of the battery box 100. During battery pack assembly, multiple tooling components can be spaced apart along the length of each long side plate 111 to guide the installation of the battery module 200. After the battery module 200 is installed into the battery box 100, the periphery of the battery module 200 abuts against the limiting surface 311 of the corresponding tooling body 300, forming a clamping limit to achieve stable and reliable positioning of the battery module 200 and the battery box 100 along the width direction of the battery box 100. Wherein, as... Figure 1 The direction shown is a, which is the width direction of the battery box 100, and b, which is the length direction of the battery box 100. The width direction of the battery box 100 is the same as the length direction of the battery cell 210, and the length direction of the battery box 100 is the same as the width direction of the battery cell 210.

[0064] For example, the distance L1 between the limiting surface 311 of the tooling body 300 on one of the two long side plates 111 and the limiting surface 311 of the tooling body 300 on the other is equal to the length L2 of the single row of battery cells 210, so as to ensure the positioning accuracy of the battery module 200 when it is installed in the battery box 100. The dimensional tolerance of L1 is equal to the allowable positional tolerance of the battery module 200 when it is installed in the battery box 100.

[0065] For example, the width B1 of the limiting surface 311 and the width B2 of the guiding surface 312 are both smaller than the width B3 of the cell 210 of the battery module 200, so that a single tooling body 300 contacts only a single row of cells 210. In this embodiment, compared to a single tooling body 300 contacting at least two rows of cells 210, a single tooling body 300 contacting only a single row of cells 210 allows for a more uniform force between the tooling body 300 and the battery module 200, effectively preventing misalignment between rows of cells 210.

[0066] For example, the number of tooling components on the same long side plate 111 is less than the number of columns of the battery module 200 including the cells 210, which can reduce friction and facilitate the installation of the battery module 200 into the battery box 100.

[0067] In one feasible implementation, such as Figure 6 As shown, the guide fixture also includes a fixing member 600, which has multiple fixture components spaced apart along its length. For example, the fixing member 600 can correspond one-to-one with the long side plate 111, meaning all fixture components mounted on the same long side plate 111 are fixed to the same fixing member 600. The fixing member 600 facilitates maintaining the spacing between the fixture components, making it easy to position and install the fixture components on the long side plate 111, ensuring a stable spacing between the fixture components, and improving the overall stability of the guide fixture.

[0068] For example, the fastener 600 can be rod-shaped to facilitate molding and manufacturing.

[0069] For example, the fastener 600 may be provided with a positioning groove or positioning protrusion to accommodate the tooling body 300, so as to realize the positioning assembly between the fastener 600 and the tooling assembly.

[0070] For example, the middle part 320 of the tooling body 300 is connected to the fastener 600.

[0071] For example, the tooling body 300 can be fixed to the fastener 600 by means of threaded connection, snap-fit ​​or welding.

[0072] In this embodiment, the battery box 100 has crossbeams (not shown) on both sides along its own length direction. The two crossbeams can form a limiting fit with the battery module 200 along the length direction of the battery box 100 to realize the positioning of the battery module 200 and the battery box 100 along the length direction of the battery box 100, which is stable and reliable.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
