[0012] Furthermore, the various features described below can be combined in the embodiments of the present application as long as they do not conflict with each other.
[0013] As in the Fig. 1 and Fig. Figure 2 shows an embodiment of a battery device according to the present application comprising a base plate 10 and a frame 20. The base plate 10 has a basin-shaped structure and a receiving chamber 30 for receiving the battery is formed in the base plate 10. The base plate 10 comprises side plates 11, which are arranged at an angle to the base plate 10, and optionally the angle between the side plates 11 and the base plate 10 is in the range of 5° to 175°. As shown in Figure 2, the base plate 10 has a base plate 10 that can be mounted on a base plate 10. The base plate 10 has a base plate 10 that can be mounted on ... Fig. As can be seen in Figure 2, the upper part of the side plates 11 is further provided with a flange 12, and the flange 12 folds towards the receiving space 30. In this embodiment, the side plates 11 and the flange 12 are arranged vertically, but they can also be arranged at other angles.
[0014] As in Fig. 1 and Fig. As shown in Figure 2, at least one frame 20 is provided, the frame 20 is arranged along the edge of the base plate 10 and at least one frame 20 is arranged on the inside of the side plate 11. ... Fig. As can be seen in Figure 2, the frame 20 has an outer surface 21 and a top surface 22, the side plate 11 covers the outer surface 21 of the frame 20, and the flange 12 covers at least part of the top surface 22 of the frame 20.
[0015] Furthermore, the frame 20 is bent from a profile to form a cavity 40. As shown from Fig. As can be seen in Figure 2, the frame 20 has a side section facing the receiving space 30 and a side section facing away from the receiving space 30, and the space between the two side sections of the frame 20 forms the cavity 40. A through-hole 50 is provided on a side of the frame 20 facing the receiving space 30, and the outer surface 21 of the frame 20 is welded to the side plate 11 and / or the top surface 22 is welded to the flange (12).
[0016] With the technical solution of this embodiment, the base plate 10 of the battery device is designed in a basin shape, creating an integrated structure between the base plate and the side plates 11 that provides excellent sealing. A frame 20 is located on the inside of the side plates 11, and a through-hole 50 is provided in the frame 20. The through-hole 50 reduces the overall weight of the battery pack, increases the ventilation space in the event of a battery failure, and provides electrolyte inlet and outlet for electrophoresis of the frame 20. Furthermore, the through-holes offer clearance for welding equipment when welding the frame 20 and side plates 11. The technical solution of this embodiment thus overcomes the problem of poor sealing performance in prior art battery pack housings.
[0017] First, it should be noted that in this embodiment, “inside” and “inner side” refer to the side facing the recording space 30, and “outside” and “outer side” refer to the side facing away from the recording space 30.
[0018] As in Fig. 1 and Fig. As shown in Figure 2, the base plate 10 of this embodiment has a basin-shaped structure, i.e., the base plate has a bottom edge and side plates 11. Optionally, the base plate 10 is integrally formed by stamping, i.e., this eliminates weld seams between the bottom edge and the side plates 11, thus ensuring the sealing performance of the box body. The upper part of the side plate 11 is also provided with an inwardly extending flange 12, and the cross-section at the edges of the base plate 10 forms a "⊏"-shaped structure. Furthermore, the flange 12 can completely or partially cover the top surface 22 of the frame 20.
[0019] Optionally, in this embodiment, the frame 20 is formed by rollers. As in Fig. 1 and Fig. As shown in Figure 2, the frame 20 has a long strip structure. The frame 20 is bent from a profile to form a cavity 40, and the cross-section of the cavity 40 is essentially square. By arranging the frame 20, the structural strength of the base plate 10 can be increased, and the sealing performance of the base plate 10 can be further improved. As shown in Figure 2, the frame 20 has a long strip structure. Fig. As can be seen in Figure 2, the surface of the frame 20 facing the recording space 30 is the inner surface 24, the surface of the frame 20 facing away from the recording space 30 is the outer surface 21, the surface of the frame 20 facing away from the base plate 10 is the top surface 22 and the surface of the frame 20 facing the base plate 10 is the bottom surface.
[0020] In the technical solution of this embodiment, the underside surface of the frame 20 is arranged in contact with the base plate 10, and the outer surface 21 of the frame 20 is welded to the side plate 11. During the welding process, the through-hole 50 can provide a clearance for the welding tool; that is, the welding tool can extend into the cavity 40, thereby improving the weld quality.
[0021] As from Fig. As can be seen in Figure 2, the top surface 22 of the frame 20 is connected to the flange 12 by a fastening element.
[0022] In some embodiments not shown, the top surface 22 of the frame 20 can also be connected to the flange 12 by welding. In this embodiment, the outer surface 21 of the frame 20 can also be connected to the side plate 11 by a fastening element.
[0023] In some embodiments not shown, the outer surface 21 of the frame 20 is welded to the side plate 11 and the top surface 22 of the frame 20 is welded to the flange 12.
[0024] In this embodiment, several frames 20 are provided, and these frames 20 are located on the inside of the side plate 11. In some embodiments not shown, some of the frames 20 may also be arranged on the outside of the side plate 11. This means that at least one frame 20 is provided on the inside of the side plate 11.
[0025] Furthermore, in this embodiment, the through-hole 50 is able to reduce the overall weight of the battery pack, increase the ventilation space in the event of a battery failure, and reserve electrolyte inlets and outlets for the electrophoresis of the frame 20.
[0026] In the technical solution of this embodiment, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 is in the range of 30 mm to 500 mm.
[0027] It should be noted that the area of the through-hole 50 refers to the area of the circle enclosed by the through-hole 50, and the wall thickness of the frame 20 refers to the thickness of the frame profile. Specifically, the thicker the wall thickness of the frame 20, the larger the area of the through-hole 50, and conversely: the thinner the wall thickness of the frame 20, the smaller the area of the through-hole 50.
[0028] Optionally, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 can be selected as 30 mm, 50 mm, 100 mm, 200 mm, 300 mm, 400 mm or 500 mm, etc.
[0029] Furthermore, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 ranges from 30 mm to 500 mm when only the outer surface 21 of the frame 20 is welded to the side plate 11. Specifically, when only the outer surface 21 of the frame 20 is welded to the side plate 11, the welding tool can be inserted into the through-hole 50 and then moved linearly to weld the outer surface 21 and the side plate 11. In this case, the requirements for the range of motion of the welding tool are relatively small, so the area of the through-hole 50 can be reduced accordingly.
[0030] For example, if only the outer surface 21 of the frame 20 is welded to the side plate 11, the ratio of the area of the through hole 50 to the wall thickness of the frame 20 can be chosen as 30 mm, 50 mm, 100 mm, 200 mm, 300 mm, 400 mm or 500 mm, etc.
[0031] Furthermore, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 ranges from 31 mm to 500 mm when only the top surface 22 of the frame 20 is welded to the flange 12. Specifically, when only the top surface 22 of the frame 20 is welded to the flange 12, the welding tool, after being inserted into the through-hole 50, must first be moved upwards around a corner to weld the top surface 22 to the flange 11. In this case, the welding tool requires a relatively large range of motion, so it is necessary to increase the area of the through-hole 50 accordingly to increase the range of motion of the welding tool. That is, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 must also be increased accordingly.For example, if only the top surface 22 of the frame 20 is welded to the flange 12, the ratio of the area of the through hole 50 to the wall thickness of the frame 20 can be chosen as 31 mm, 50 mm, 100 mm, 200 mm, 300 mm, 400 mm or 500 mm, etc.
[0032] Furthermore, the ratio of the area of the through hole 50 to the wall thickness of the frame 20 is in the range of 31 mm to 500 mm when the outer surface 21 of the frame 20 is welded to the side plate 11 and the top surface 22 of the frame 20 is welded to the flange 12.
[0033] As described above, when welding the outer surface 21 of the frame 20 to the side plate 11 and the top surface 22 of the frame 20 to the flange 12, it must be taken into account that the welding tool, after being inserted into the through-hole 50, must be moved upwards by one corner before the top surface 22 and the flange 11 can be welded. Therefore, the area of the through-hole 50 must be enlarged accordingly to increase the range of motion of the welding tool. That is, the ratio of the area of the through-hole 50 to the wall thickness of the frame 20 must be increased accordingly.
[0034] For example, if the outer surface 21 of the frame 20 is welded to the side plate 11 and the top surface 22 of the frame 20 is welded to the flange 12, the ratio of the area of the through hole 50 to the wall thickness of the frame 20 can be chosen to be 31 mm, 50 mm, 100 mm, 200 mm, 300 mm, 400 mm, 500 mm, etc.
[0035] In the technical solution of this embodiment, the base plate 10 has a longitudinal and a lateral direction, and the frame 20 is a long strip structure, i.e., the frame 20 also has a longitudinal direction. As shown from Fig. As can be seen in Figure 1, the minimum distance between the edge of the through hole 50 and the end of the frame 20 along the longitudinal direction is at least 3 mm.
[0036] As from Fig. As can be seen in Figure 2, the minimum distance between the edge of the through-hole 50 and the end of the frame 20 should not be too small. If this distance is too small, the area between the edge of the through-hole 50 and the end of the frame 20 becomes thinner, which reduces the strength of the edge of the frame 20. Optionally, the minimum distance between the edge of the through-hole 50 and the end of the frame 20 can be chosen as a larger value along the longitudinal direction, such as 3 mm, 4 mm, 5 mm, etc.
[0037] As from Fig. As can be seen in Figure 1, the technical solution of this embodiment provides for several through holes 50 and the several through holes 50 are arranged at intervals along the longitudinal direction of the frame 20.
[0038] It should be noted that the expression "multiple through holes 50" means that at least two through holes 50 are present.
[0039] In particular, multiple through-holes provide more clearance for welding tools, thus facilitating welding processes and improving weld quality. Furthermore, the multiple through-holes increase the ventilation space and further reduce the overall weight of the battery.
[0040] In some embodiments not shown, several through holes 50 are provided, and the multiple through holes 50 can also be arranged at intervals in a direction perpendicular to the base plate 10. That is, the multiple through holes 50 can also be arranged along the up-down direction of Fig. 1 be arranged.
[0041] In the technical solution of this embodiment, the ratio of the minimum distance between adjacent through holes 50 to the depth of the cavity 40 is in the range of 0.5 to 10.
[0042] It should be noted that the aforementioned distance between adjacent through holes 50 refers to the distance between the axes of adjacent through holes 50. This distance can also refer to the minimum distance between adjacent through holes 50 when the multiple through holes 50 are arranged along the longitudinal direction of the frame 20. This distance can also refer to the minimum distance between adjacent through holes 50 when the multiple through holes 50 are arranged in a direction perpendicular to the base plate 10.
[0043] It should be noted that the aforementioned depth of the cavity 40 refers to the distance between the inner wall of the outer surface 21 of the frame 20 and the inner wall of the inner surface 24 of the frame 20, i.e., to the horizontal dimension of the cavity 40 in Fig. 2.
[0044] Furthermore, the ratio of the minimum distance between adjacent through holes 50 to the depth of the cavity 40 must not be too small. If this ratio is too small, the effectiveness of the through holes 50 cannot be guaranteed. If this ratio is too large, the strength of the frame 20 is reduced.
[0045] Optionally, the ratio of the minimum distance between adjacent through holes 50 to the depth of the cavity 40 can be 0.5, 1, 2, 5, 10, etc.
[0046] In the technical solution of this embodiment, the ratio of the minimum distance between adjacent through holes 50 to the length of the frame 20 is less than or equal to 0.6.
[0047] It should be noted that this minimum distance between adjacent through holes 50 refers to the minimum distance between adjacent through holes 50 when the multiple through holes 50 are spaced apart along the longitudinal direction of the frame 20. In particular, the longer the frame 20, the smaller the minimum distance between adjacent through holes 50 should be. Conversely, the shorter the frame 20, the larger the minimum distance between adjacent through holes 50 should be.
[0048] Optionally, the ratio of the minimum distance between adjacent through holes 50 to the length of the frame 20 can be 0.6, 0.5, 0.1 or a smaller value.
[0049] In the technical solution of this embodiment, the ratio of the wall thickness of the base plate 10 to the wall thickness of the frame 20 is in the range of 0.2 to 3.5.
[0050] It should be noted that the wall thickness of the base plate 10 refers to the thickness of the profile of the base plate 10, while the wall thickness of the frame 20 refers to the thickness of the profile of the frame 20.
[0051] To ensure the strength of the frame 20 and the airtightness of the base plate 10, the frame 20 is preferably thicker than the base plate 10. For example, the ratio of the thickness of the base plate 10 to the thickness of the frame 20 can be 0.2, 0.5, 1, 2, 3, 3.5, etc.
[0052] In the technical solution of this embodiment, the tensile strength of the base plate 10 is in the range of 120 MPa to 780 MPa and the tensile strength of the frame 20 is in the range of 590 MPa to 1500 MPa.
[0053] The strength of the base plate 10 and frame 20 should balance the weight and overall strength of the battery.
[0054] Optionally, the strength of the base plate 10 can be, among other things, 120 MPA, 200 MPA, 500 MPA, 700 MPA or 780 MPA.
[0055] Optionally, the strength of the frame 20 can be, among other things, 590 MPA, 600 MPA, 700 MPA, 1000 MPA, 1300 MPA or 1500 MPA.
[0056] As in Fig. As shown in Figure 2, in this embodiment, a recess 23 is provided on the outer surface 21 of the frame 20. The recess 23 has a long strip structure extending from the outer surface of the frame 20 to the inner surface 24.
[0057] In this embodiment, the recess 23 can not only reinforce the frame 20, but also reduce the weight of the battery device. As shown in Fig. As shown in Figure 2, the inner surface 24 of the frame 20, which faces the receiving space 30, is a flat plane in the technical solution of this embodiment. The inner surface 24 is designed to be flat in order to increase the strength of the frame.
[0058] In this embodiment, the thickness of the base plate 10 is in the range of 0.6 mm to 3 mm.
[0059] In particular, the thickness of the base plate 10 should be set to a value that ensures sealing without adding extra weight to the battery device.
[0060] Optionally, the wall thickness of the base plate 10 can be selected as 0.6 mm, 1 mm, 2 mm or 3 mm, among other options.
[0061] As in Fig. As shown in Figure 2, in the technical solution of this embodiment, the side plate 11 comprises a side wall 111 and a top wall 112, wherein the side wall 111 abuts the outer surface of the frame 20 and the top wall 112 is congruent with the top surface 22 of the frame 20. As would be apparent to a person skilled in the art from Fig. As can be seen in Figure 2, the ceiling wall 112 forms the aforementioned flange 12.
[0062] In particular, the side panel 11 has an L-shaped structure, with the side wall 111 being arranged perpendicular to the base panel 10 and the side wall 111 abutting the outer surface 21 of the frame 20. The top wall 112 runs parallel to the base panel 10 and abuts the upper surface 22 of the frame 20.
[0063] In this embodiment, the overlap area between the base plate 10 and the frame 20 can be increased by arranging the side wall 111 and the ceiling wall 112, thereby ensuring the sealing performance of the battery.
[0064] Optionally, the welds between the frame 20 and the side plate 11 are intermittent welds, which saves welding costs and improves welding efficiency.
[0065] Obviously, the above embodiments are merely examples for the purpose of clear description and do not constitute limitations on the embodiments. For general technical personnel, other different forms of changes or modifications may be made based on the above description. A complete list of all embodiments is neither necessary nor possible. The obvious changes or modifications derived therefrom still fall within the scope of protection of the present application.
