In this way, it is not necessary to arrange a longitudinal beam in the frame body 110, and the longitudinal beam is replaced by the support 130, so as to increase the working space in the frame body 110 and reduce the weight of the frame structure 100.

[0061] It can be understood that the number of supports 130 is at least two. For example, the number of supports 130 is two, and the two supports 130 are arranged on the two sides of the cross beam 120 respectively. The number of supports 130 can also be three, wherein two supports 130 are arranged on the same side of the cross beam 120, and the other support 130 is arranged on the other side of the cross beam 120. The number of supports 130 can also be more than three, as long as there is at least one support 130 on one side of the cross beam 120. The number of supports 130 is not limited in the embodiments of the present application.

[0062] For the convenience of understanding the direction, Figure 1 and Figure 2 An X-Y plane coordinate system is established in the frame body 110, wherein the direction in which the X axis is located is the first direction, and the direction in which the Y axis is located is the second direction.

[0063] In some embodiments, referring to Figure 1 As shown, the cross beam 120 can be arranged in the frame body 110 along the first direction, and the two supports 130 can be arranged along the second direction, and the first direction intersects with the second direction, so as to facilitate the fixation of the straight bus bar 300.

[0064] Preferably, the first direction is perpendicular to the second direction, so that the overall structure is more compact.

[0065] In other embodiments, referring to Figure 2 As shown, the cross beam 120 can be arranged in the frame body 110 along the first direction, and the two supports 130 can be arranged in the second direction, and the first direction intersects with the second direction, so as to facilitate the fixation of the straight bus bar 300.

[0066] It can be understood that the material of the bus bar 300 can be copper, nickel, silver, gold-plated material, and other alloy materials, as long as it can be connected in series and parallel to each battery cell group 200. The embodiments of the present application do not make too many limitations.

[0067] In some embodiments, referring to Figure 1 ,Figure 4 and Figure 5 As shown in FIG. 1, the mounting assembly 140 includes a first mounting member 141 and a second mounting member 142.

[0068] The first mounting member 141 is arranged on the cross beam 120 and the support member 130, and the second mounting member 142 is arranged opposite to the first mounting member 141. The first mounting member 141 and the second mounting member 142 enclose a mounting position for mounting the busbar 300.

[0069] The second mounting member 142 is configured to move towards the first mounting member 141 and clamp the busbar 300 with the first mounting member 141.

[0070] In the above embodiment, the first mounting member 141 of each mounting assembly 140 is arranged on the cross beam 120 and the support member 130, respectively, and encloses a mounting position with the second mounting member 142. By placing the busbar 300 in the mounting position and moving the second mounting member 142 towards the first mounting member 141, the busbar 300 can be clamped and fixed on the cross beam 120 and the support member 130. In this way, the busbar 300 can be conveniently installed, thereby improving the installation efficiency.

[0071] In some specific embodiments, referring to FIG. 2, the mounting assembly 140 further includes a bundling belt 143. Figure 5

[0072] The first mounting member 141 is provided with a first through hole 1411, and the second mounting member 142 is provided with a second through hole 1421. One end of the bundling belt 143 passes through the first through hole 1411 and the second through hole 1421 in sequence and is connected with the other end. The bundling belt 143, the first mounting member 141 and the second mounting member 142 enclose a mounting position for mounting the busbar 300.

[0073] The second mounting member 142 is configured to tighten the bundling belt 143 to move towards the first mounting member 141.

[0074] In the above embodiment, the bundling belt 143 passes through the first through hole 1411 on the first mounting member 141 and the second through hole 1421 on the second mounting member 142 in sequence, thereby connecting the first mounting member 141 and the second mounting member 142. The bundling belt 143, the first mounting member 141 and the second mounting member 142 collectively enclose a mounting position. After the busbar 300 is placed in the mounting position, the bundling belt 143 is tightened to move the second mounting member 142 towards the first mounting member 141 to clamp the busbar 300.

[0075] It can be understood that the bundling belt 143 can be an insulating cable tie, a bandage, or other similar structures, and the embodiments of the present application do not make too many limitations thereon. ​

[0076] In some specific embodiments, the first mounting member 141 can be a U-shaped structure, and the second mounting member 142 is arranged between two side walls of the U-shaped structure to move towards the first mounting member 141 to clamp the busbar 300.

[0077] Of course, the mounting assembly 140 can also be other structures similar to the above, as long as the second mounting member 142 can move towards the first mounting member 141 to clamp the busbar 300, and the present application does not make too many limitations on this.

[0078] Specifically, referring to FIGS. 1 and 2, the first mounting member 141 is arranged on the support member 130. Figure 4 Figure 5 As shown in FIGS. 1 and 2, the side of the first mounting member 141 facing the second mounting member 142 is provided with a pad 1413.

[0079] Referring to FIGS. 1 and 2, the direction of the Z-axis is the third direction. In the actual installation process, the height of the cross beam 120 in the third direction and the height of the support member 130 in the third direction will have a height difference, and the pad 1413 is arranged to eliminate the height difference of the cross beam 120 and the support member 130 in the third direction, so as to ensure that each mounting assembly 140 is located on the same horizontal plane, thereby facilitating the installation of the busbar 300. Figures 3 to 5 For example, referring to FIGS. 1 and 2, the height of the cross beam 120 in the third direction is higher than the height of the support member 130 in the third direction, and the first mounting member 141 arranged on the support member 130 is provided with a pad 1413 to eliminate the height difference.

[0080] Figures 3 to 5 Among them, the third direction can be a vertical direction.

[0081] In some embodiments, referring to FIGS. 1 and 2, the first mounting member 141 is provided with a connecting portion 1412, and the cross beam 120 and the support member 130 are both provided with connecting holes, and the connecting portion 1412 is arranged in the connecting holes.

[0082] In the above embodiments, the first mounting member 141 can be arranged on the cross beam 120 and the support member 130 through the connecting portion 1412, respectively. Figure 3 Figure 5 For example, referring to FIGS. 1 and 2, the height of the cross beam 120 in the third direction is higher than the height of the support member 130 in the third direction, and the first mounting member 141 arranged on the support member 130 is provided with a pad 1413 to eliminate the height difference.

[0083] In the above embodiments, the first mounting member 141 can be arranged on the cross beam 120 and the support member 130 through the connecting portion 1412, respectively.

[0084] For example, referring to FIGS. 1 and 2, the height of the cross beam 120 in the third direction is higher than the height of the support member 130 in the third direction, and the first mounting member 141 arranged on the support member 130 is provided with a pad 1413 to eliminate the height difference. Figure 1 ​​​As shown, the connecting portion 1412 can be a snap element, which is snapped with the connecting hole to arrange each first mounting element 141 on the cross beam 120 and the support element 130. Of course, the connecting portion 1412 can also be a hollow rivet, which extends into the connecting hole to arrange each first mounting element 141 on the cross beam 120 and the support element 130. The connecting portion 1412 can also be other structures similar to the above, and the embodiments of the present application do not make too many limitations in this regard.

[0085] In some embodiments, with reference to Figure 1 and Figure 3 As shown, the support element 130 includes a first support portion 131 and a second support portion 132.

[0086] The first support portion 131 is arranged in the frame body 110, and the second support portion 132 is sleeved on the first support portion 131. The first support portion 131 is provided with a first perforation 1311, and the second support portion 132 is provided with a second perforation 1321. The first perforation 1311 corresponds to the second perforation 1321 to form a connecting hole.

[0087] In the above embodiments, the first support portion 131 can be fixed to the bottom of the frame body 110, and the second support portion 132 is sleeved on the first support portion 131 to correspond the first perforation 1311 to the second perforation 1321 to form a connecting hole. After the connecting portion 1412 extends into the connecting hole, the relative movement between the first support portion 131 and the second support portion 132 is limited. This structure can facilitate installation and improve installation efficiency.

[0088] For example, the shape of the first support portion 131 can be a cuboid, a cube, a cylinder, or other shapes, and the embodiments of the present application do not make too many limitations in this regard. The shape of the second support portion 132 can be a sleeve that matches the shape of the first support portion 131, and the embodiments of the present application do not make too many limitations in this regard.

[0089] In some specific embodiments, with reference to Figure 3 As shown, the first support portion 131 is provided with a weight-reducing hole 1312.

[0090] In the above embodiments, the first support portion 131 is provided with a weight-reducing hole 1312, which is mainly used to reduce the weight of the first support portion 131, thereby reducing the weight of the frame structure 100.

[0091] For example, with reference to Figure 3As shown, the first support part 131 can be a cuboid structure, and a weight-reducing hole 1312 is arranged on the first support part 131 for reducing weight, and a reinforcing section 1313 is arranged in the weight-reducing hole 1312 for reinforcing the connection strength of the first support part 131, and the second support part 132 can be a sleeve of a cuboid, and the second support part 132 is sleeved on the first support part 131, so that the support piece 130 can further reduce the weight of the support piece 130 while ensuring the connection strength.

[0092] In some embodiments, with reference to Figure 3 As shown, the first support part 131 is connected to the bottom of the frame body 110 by at least one fastener 133.

[0093] It can be understood that the number of fasteners 133 is at least one, for example, the fastener 133 can be one, and the fastener 133 can also be two or more, as long as it can ensure that the first support part 131 can be connected to the bottom of the frame body 110 by the fastener 133, and the number of support pieces 130 is not limited too much in the embodiments of the application.

[0094] Of course, when the number of fasteners 133 is two or more, the relative rotation of the first support part 131 relative to the frame body 110 can be prevented.

[0095] For example, the fastener 133 can be a pull rivet nut, a core-pulling rivet, and other similar structures, and the number of support pieces 130 is not limited too much in the embodiments of the application.

[0096] The first support part 131 can also be glued to the bottom of the frame body 110 by connecting glue.

[0097] By using connecting glue to bond the first support part 131 and the bottom of the frame body 110, a sealing effect can be achieved. The connecting glue can be a heat-conducting structural glue.

[0098] In a preferred embodiment, the first support part 131 is connected to the bottom of the frame body 110 by at least one fastener 133, and the connecting glue is filled between the first support part 131 and the frame body 110, the fastener 133 and the first support part 131, and the fastener 133 and the frame body 110, which further improves the sealing performance while improving the connection strength.

[0099] In some embodiments, an insulating piece is arranged outside the support piece 130.

[0100] In the above embodiments, the insulating piece is arranged to prevent the support piece 130 from conducting electricity during use, thereby ensuring insulation safety.

[0101] For example, the insulation member can be a fireproof belt, which is wound on the outer side of the insulation member to ensure insulation safety.

[0102] Referring to Figure 1 and Figure 6 , the battery pack provided by the present application comprises a plurality of cell groups 200, busbars 300 and the frame structure 100 as above.

[0103] The cell groups 200 are arranged in the frame body 110 of the frame structure 100, the busbars 300 are arranged on the mounting assembly 140 of the frame structure 100, and the plurality of cell groups 200 are connected through the busbars 300.

[0104] In the embodiments of the present application, since the battery pack adopts the frame structure 100 in the above embodiments, it also has the advantages and benefits brought by the frame structure 100, that is, it can reduce the volume and weight of the battery pack.

[0105] For example, referring to Figure 1 and Figure 2 , the frame body 110 is provided with three parallel beams 120, and the two beams 120 on both sides form an electrical cavity 112 with the inner side wall of the frame body 110, which is used to place electrical elements. Each support 130 is arranged between two adjacent beams 120 to form four placement positions 111, each of which is used to place a cell group 200. Each beam 120 and each support 130 is provided with a mounting assembly 140.

[0106] Among them, after placing four cell groups 200 on each placement position 111 respectively, the busbars 300 are fixed through the mounting assemblies 140, and the two ends of the busbars 300 are respectively located in the two electrical cavities 112 to be connected with the electrical elements in the electrical cavities 112. In this way, the structure in the frame body 110 can be more compact and avoid interference with each other.

[0107] Specifically, referring to Figure 1 and Figure 2 , the distance between the two adjacent mounting assemblies 140 can be equal, and the distance between the two adjacent mounting assemblies 140 can be 210 mm.

[0108] The vehicle provided by the present application comprises a vehicle body and the battery pack as above, and the battery pack is arranged in the vehicle body.

[0109] In the above structure, since the vehicle adopts the battery pack in the above embodiments, it also has the advantages and benefits brought by the battery pack, which will not be described here.
