Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0036] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0037] Example 1

[0038] like Figures 1 to 4 , Figures 8 to 10As shown, this embodiment provides a battery pack with intersecting first direction X and second direction Y. The battery pack includes a first side beam 10, a second side beam 20, a first adapter 30, a first snap-fit ​​portion 40, and a first plug-in portion 50. The first side beam 10 extends along the first direction X; the second side beam 20 extends along the second direction Y; the first adapter 30 is disposed at the intersection of the extension trajectory of the first side beam 10 and the extension trajectory of the second side beam 20, and is connected to the first side beam 10 and the second side beam 20 respectively; the first plug-in portion 50 includes a first protrusion 51 and a second protrusion 52 extending toward the side where the first snap-fit ​​portion 40 is located, the first protrusion 51 and the second protrusion 52 being spaced apart from each other; the first protrusion 51 has a first end face 511 facing the first snap-fit ​​portion 40, and the second protrusion 52 has a first end face 511 facing the first snap-fit ​​portion 40. The second end face 521 of the latching part 40 has different shapes from the first end face 511 and the second end face 521; the first protrusion 51 and the second protrusion 52 are both used to insert into the first latching part 40; the first latching part 40 is disposed at one end of the second side beam 20 along the second direction Y toward the first adapter 30; the first insertion part 50 is disposed at one end of the first adapter 30 along the second direction Y toward the second side beam 20; the battery pack also has a third direction Z, and the first direction X, the second direction Y and the third direction Z intersect each other; the first protrusion 51 and the second protrusion 52 are arranged along the third direction Z.

[0039] In the battery pack of this embodiment, the first end face 511 and the second end face 521 on the first plug-in portion 50 have different shapes. During the assembly stage, it is ensured that the first plug-in portion 50 is inserted into the first snap-fit ​​portion 40 at the correct angle to prevent the first plug-in portion 50 and the first snap-fit ​​portion 40 from being reversed or incorrectly installed.

[0040] It should be noted that in this embodiment, the first end face 511 and the second end face 521 have different shapes. When the first insertion part 50 is inserted into the first latching part 40 in the correct direction and angle, the first insertion part 50 can be smoothly embedded in the first latching part 40. When the first insertion part 50 is inserted into the first latching part 40 in the wrong direction or at the wrong angle, the first insertion part 50 and the first latching part 40 cannot be aligned, and the first insertion part 50 cannot be embedded in the first latching part 40.

[0041] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the first snap-fit ​​part 40 is integrally formed with the second side beam 20, the first plug-in part 50 is integrally formed with the first adapter 30, and one end of the first adapter 30 along the first direction X is integrally formed with the first side beam 10.

[0042] like Figure 2As shown, specifically, the first snap-fit ​​portion 40 includes a first cavity 41 and a second cavity 42 that are spaced apart from each other; the first cavity 41 and the second cavity 42 are respectively opposite to the first protrusion 51 and the second protrusion 52 along the second direction Y, and the first protrusion 51 and the second protrusion 52 are respectively inserted into the first cavity 41 and the second cavity 42.

[0043] like Figures 2 to 4 As shown, the first insertion portion 50 also includes a third protrusion 53, which extends along the second direction Y toward the side where the first snap-fit ​​portion 40 is located, and the third protrusion 53 is located between the first protrusion 51 and the second protrusion 52; the third protrusion 53 is used to insert into the first snap-fit ​​portion 40.

[0044] like Figure 2 As shown, the first snap-fit ​​portion 40 also includes a third cavity 43, which is opposite to the third protrusion 53 along the second direction Y. The third protrusion 53 is inserted into the third cavity 43, and the third cavity 43 is located between the first cavity 41 and the second cavity 42.

[0045] Specifically, there are two of each of the third protrusion 53 and the third cavity 43.

[0046] It should be noted that those skilled in the art can adjust the specific number of the third protrusion 53 and the third cavity 43 according to actual needs.

[0047] like Figure 2 As shown, specifically, the first snap-fit ​​part 40 is integrally formed with the second side beam 20. The second side beam 20 has a cavity, and three first ribs 21 are provided in the cavity. The three first ribs 21 divide the cavity to form a first cavity 41, a second cavity 42 and two third cavities 43.

[0048] Specifically, the angle formed between each of the first reinforcing bars 21 and the inner wall of the cavity of the second side beam 20 is not a right angle (that is, the angle is not equal to 90°).

[0049] It should be noted that those skilled in the art can adjust the specific angle formed by the cavity between the first rib 21 and the inner wall of the second side beam 20 according to actual needs.

[0050] It is worth noting that by setting the first rib 21, the structural strength of the second side beam 20 is enhanced, and at the same time, it is convenient to quickly assemble the first protrusion 51, the second protrusion 52, and the third protrusion 53 with the first cavity 41, the second cavity 42, and the third cavity 43 respectively; by setting the third protrusion 53, the docking accuracy between the first insertion part 50 and the first snap-fit ​​part 40 is further improved.

[0051] like Figure 4 As shown, a first groove 512 is provided at the end of the first protrusion 51 facing away from the second protrusion 52 along the third direction Z, and the first groove 512 extends along the second direction Y; as Figure 2 As shown, a first protrusion 22 is provided in the first cavity 41, and the first protrusion 22 is inserted into the first groove 512.

[0052] It is worth noting that when the first adapter 30 is rotated 180°, the first boss 22 in the first cavity 41 does not match the position of the first groove 512 on the first protrusion 51, and cannot be installed, thus ensuring that the first adapter 30 is installed at the correct angle.

[0053] It should be noted that, referring to Figure 4 Alternatively, the first groove 512 can be positioned at the end of the second protrusion 52 that is away from the first protrusion 51 along the third direction Z, and the first boss 22 can be positioned inside the second cavity 42.

[0054] like Figure 10 As shown, the first protrusion 51, the second protrusion 52, the first cavity 41, and the second cavity 42 all have a cross-section perpendicular to the second direction Y; the cross-sectional area of ​​the first protrusion 51 is smaller than the cross-sectional area of ​​the first cavity 41, and the cross-sectional area of ​​the second protrusion 52 is smaller than the cross-sectional area of ​​the second cavity 42; the first protrusion 51 has a first abutting surface 513 on the side away from the second protrusion 52 along the third direction Z, and the first abutting surface 513 abuts against the first cavity 41; the second protrusion 52 has a second abutting surface 522 on the side away from the first protrusion 51 along the third direction Z, and the second abutting surface 522 abuts against the second cavity 42.

[0055] like Figure 10 As shown, the first protrusion 51 has a third abutting surface 514, which abuts against the first cavity 41; the second protrusion 52 has a fourth abutting surface 523, which abuts against the second cavity 42; the third abutting surface 514 and the fourth abutting surface 523 intersect.

[0056] It is worth noting that the cross-sectional area of ​​the first protrusion 51 is smaller than that of the first cavity 41, and the cross-sectional area of ​​the second protrusion 52 is smaller than that of the second cavity 42, so as to facilitate the quick installation of the first snap-fit ​​part 40 and the first insertion part 50; the first abutting surface 513 abuts against the first cavity 41, and the second abutting surface 522 abuts against the second cavity 42, so as to restrict the longitudinal movement of the first insertion part 50 within the first snap-fit ​​part 40, making the connection between the first side beam 10 and the second side beam 20 more stable; the third abutting surface 514 abuts against the first cavity 41, and the fourth abutting surface 523 abuts against the second cavity 42, and the third abutting surface 514 and the fourth abutting surface 523 intersect, so as to restrict the lateral movement of the first insertion part 50 within the first snap-fit ​​part 40, making the connection between the first side beam 10 and the second side beam 20 more stable.

[0057] Specifically, the third protrusion 53 has a third end face 531 facing the first snap-fit ​​portion 40, and the shape of the third end face 531 is different from that of the first end face 511 and the second end face 521.

[0058] like Figure 4 As shown, the first protrusion 51, the second protrusion 52 and the third protrusion 53 each have a cross section perpendicular to their respective extension direction. The cross section of the first protrusion 51 is polygonal, the cross section of the second protrusion 52 is polygonal, and the cross section of the third protrusion 53 is triangular.

[0059] It should be noted that those skilled in the art can adjust the cross-sectional shape of the first protrusion 51, the second protrusion 52, and the third protrusion 53 according to actual needs.

[0060] It should be noted that the cross-sectional shapes of the first protrusion 51, the second protrusion 52, and the third protrusion 53 can be the same. For example, the cross-sectional shapes of the first protrusion 51, the second protrusion 52, and the third protrusion 53 are all triangular, but the size of each protrusion or the orientation of its included angle may differ.

[0061] like Figure 1 and Figure 3 As shown, in this embodiment, the battery pack also includes a third side beam 80 and a fourth side beam 90. The third side beam 80 extends along the first direction X, and the fourth side beam 90 extends along the second direction Y. The two ends of the third side beam 80 are respectively connected to the second side beam 20 and the fourth side beam 90, and the two ends of the fourth side beam 90 are respectively connected to the third side beam 80 and the first side beam 10.

[0062] like Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, the battery pack also includes a top cover 101, a battery module 102, a cooling plate 103, and a bottom plate 104. The top cover 101 and the bottom plate 104 are respectively connected to the side beam structure to enclose and form an installation cavity 105. The battery module 102 and the cooling plate 103 are disposed in the installation cavity 105.

[0063] Example 2

[0064] The difference between Example 2 and Example 1 is as follows: Figures 5 to 7As shown, the battery pack also includes a second insertion portion 60 and a second snap-fit ​​portion 70. The second snap-fit ​​portion 70 is disposed at one end of the first side beam 10 facing the first adapter 30 along the first direction X. The second insertion portion 60 is disposed at one end of the first adapter 30 facing the first side beam 10 along the first direction X. The second insertion portion 60 has a fourth protrusion 61, which extends toward the side where the second snap-fit ​​portion 70 is located and is used to insert into the second snap-fit ​​portion 70. The fourth protrusion 61 has a fourth end face 611 facing the second snap-fit ​​portion 70. The shape of the fourth end face 611 is different from that of the first end face 511 and the second end face 521.

[0065] It is worth noting that the shape of the fourth end face 611 is different from that of the first end face 511 and the second end face 521. That is, the second insertion part 60 is different from the first insertion part 50. This is to quickly confirm the corresponding positions of the first insertion part 50 and the second insertion part 60 with the first snap-fit ​​part 40 and the second snap-fit ​​part 70 respectively during the assembly stage, so as to facilitate rapid assembly and ensure the correct installation of the first adapter 30.

[0066] like Figure 7 As shown, specifically, the second snap-fit ​​part 70 is integrally formed with the first side beam 10, the second plug-in part 60 is integrally formed with the first adapter 30, and the first adapter 30, which is provided with the first plug-in part 50 and the second plug-in part 60, is detachably connected to the first side beam 10 and the second side beam 20 respectively.

[0067] like Figure 6 and Figure 7 As shown, specifically, the second insertion part 60 also has a fifth protrusion 62 and a sixth protrusion 63. Correspondingly, the second snap-fit ​​part 70 includes a fourth cavity 71, a fifth cavity 72 and a sixth cavity 73. The fourth protrusion 61, the fifth protrusion 62 and the sixth protrusion 63 are respectively inserted into the fourth cavity 71, the fifth cavity 72 and the sixth cavity 73.

[0068] Specifically, the first side beam 10 has a cavity, and three second ribs 11 are provided in the cavity. The three second ribs 11 divide the cavity to form a fourth cavity 71, a fifth cavity 72 and a sixth cavity 73.

[0069] Specifically, the fourth protrusion 61, the fifth protrusion 62 and the sixth protrusion 63 each have a cross section perpendicular to their respective extension direction. The cross section of the fourth protrusion 61 is polygonal, the cross section of the fifth protrusion 62 is square, and the cross section of the sixth protrusion 63 is polygonal.

[0070] like Figure 7 As shown, the fourth protrusion 61 has a second groove 612 at one end opposite to the sixth protrusion 63 along the third direction Z, and the second groove 612 extends along the first direction X; as Figure 6 As shown, the fourth cavity 71 is provided with a second protrusion 12, which is engaged in the second groove 612.

[0071] Apart from the above, the other structures and configurations of Example 2 are the same as those of Example 1, so they will not be described again.

[0072] Example 3

[0073] The difference between Embodiment 3 and Embodiment 1 is that: the first snap-fit ​​part 40 is disposed at one end of the first side beam 10 along the first direction X toward the first adapter 30; the first plug-in part 50 is disposed at one end of the first adapter 30 along the first direction X toward the first side beam 10; the first snap-fit ​​part 40 is integrally formed with the first side beam 10, the first plug-in part 50 is integrally formed with the first adapter 30, and one end of the first adapter 30 along the second direction Y is integrally formed with the second side beam 20.

[0074] Specifically, the third protrusion 53 extends along the first direction X toward the side where the first snap-fit ​​portion 40 is located, and the third cavity 43 is disposed opposite to the third protrusion 53 along the first direction X; the first rib 21 is disposed in the cavity of the first side beam 10; and the first groove 512 extends along the first direction X.

[0075] Apart from the above, the other structures and configurations of Example 3 are the same as those of Example 1, so they will not be described again.

[0076] Example 4

[0077] The difference between Embodiment 4 and Embodiment 1 is that: the first snap-fit ​​part 40 is disposed at one end of the first adapter 30 along the second direction Y toward the second side beam 20; the first insertion part 50 is disposed at one end of the second side beam 20 along the second direction Y toward the first adapter 30; the first snap-fit ​​part 40 and the first adapter 30 are integrally formed, the first insertion part 50 and the second side beam 20 are integrally formed, and one end of the first adapter 30 along the first direction X is integrally formed with the first side beam 10; the first rib 21 is disposed in the cavity of the first adapter 30.

[0081] Apart from the above, the other structures and configurations of Example 5 are the same as those of Example 1, and therefore will not be described again.

[0082] Example 6
