[0038] For further information, please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a planar structure of one side of a battery pack 100 provided in an embodiment of the present application; Figure 2 It is a schematic structural diagram of a crossbeam 20 and an insulating sheath 50 provided in an embodiment of the present application.

[0039] like Figure 1 and Figure 2 As shown, the battery pack 100 of the present application includes an upper cover (not shown in the figure), a battery tray 10 and an electrical component 30. The upper cover is fixedly connected to the battery tray 10 to form a receiving cavity, and the electrical component 30 is received in the receiving cavity and carried by the battery tray 10. Further, the battery tray 10 includes a tray body 11 and a crossbeam 20. The tray body 11 has a receiving groove 111, and the electrical component 30, the crossbeam 20 and other functional components are all received in the receiving groove 111. The tray body 11 includes a bottom plate 12, and the electrical component 30 and the crossbeam 20 are both fixed on the plane of the bottom plate 12. There are two electrical components 30, and the two electrical components 30 are arranged side by side and spaced apart along a first direction 001, and the crossbeam 20 is arranged between the two electrical components 30, and the crossbeam 20 extends along a second direction 002 to separate the two electrical components 30. Or it can be understood that the crossbeam 20 is disposed in the receiving groove 111 of the tray body 11 and extends along the second direction 002 to divide the receiving groove 111 into two sub-receiving grooves, and an electrical component 30 is disposed in each sub-receiving groove. Among them, the first direction 001 is the arrangement direction of the two electrical components 30, the second direction 002 is the length direction of the crossbeam 20 itself, and the first direction 001 and the second direction 002 are perpendicular to each other.

[0040] It should be noted that the crossbeam 20 is usually made of metal material, and the crossbeam 20 can not only separate the two electrical components 30 and block the heat transfer between the two electrical components 30, but also serve as a supporting beam of the tray body 11, thereby improving the strength of the tray body 11 and preventing the electrical components 30 from being damaged when the battery pack 100 is collided or squeezed.

[0041] Further, the crossbeam 20 has two side walls 21, each of which faces one of the electrical components 30. The crossbeam 20 is also provided with an opening 22, which is located on the side of the crossbeam 20 away from the bottom plate 12, and the opening 22 penetrates the two side walls 21 along the first direction 001. Or it can be understood that the side of the crossbeam 20 away from the bottom plate 12 is provided with a groove 23, and the groove 23 connects the two sub-receiving grooves.

[0042] Please cooperate Figure 3 As shown, Figure 3 It is a schematic diagram of an exploded view of a beam 20 and an insulating sheath 50 provided in one embodiment of the present application from one side perspective.

[0043] like Figures 1 to 3As shown, the battery tray 10 of the present application also includes a connecting component 40. The connecting component 40 spans the beam 20 through the opening 22 and connects two electrical components 30 located on opposite sides of the beam 20. The connecting component 40 enables the two electrical components 30 to achieve conductive connection. Specifically, the connecting component 40 includes a connecting row 41 and an insulating layer (not shown in the figure), and the insulating layer is partially wrapped around the periphery of the connecting row 41 to prevent the connecting row 41 from being exposed to conduct with other irrelevant components or causing the danger of high-voltage electric shock to operators. There are two connecting rows 41, and the two connecting rows 41 extend relatively to each other and extend into the opening 22 of the beam 20 respectively, that is, extend into the groove 23 of the beam 20. The groove 23 avoids the connecting row 41 while also supporting the connecting row 41. The two connecting rows 41 are fixedly connected at the opening 22 to conduct the two electrical components 30.

[0044] It should be noted that. The two connection rows 41 are exposed to the insulating layer at the opening 22 to ensure that the two connection rows 41 can achieve conductive connection. Therefore, a protective device needs to be provided at the opening 22 to perform insulation protection after the two connection rows 41 are connected to prevent the exposed connection rows 41 from being connected to the crossbeam 20 or other components. Specifically, each connection row 41 includes a connected lead-out section 411 and a fixed section 412. The lead-out section 411 is closer to the electrical component 30 than the fixed section 412 and is connected to the electrical component 30. The two connection rows 41 extend relative to each other so that the fixed section 412 is completely extended into the groove 23. The outer periphery of the lead-out section 411 is coated with an insulating layer, and the fixed section 412 is exposed to the insulating layer so that the fixed sections 412 of the two connection rows 41 are fixedly connected in the groove 23, and the two electrical components 30 can be connected. At the same time, the present application provides an insulating sheath 50 as a protective device at the opening 22. The insulating sheath 50 is sleeved around the periphery of the connecting assembly 40 , specifically around the periphery of the fixed sections 412 of the two connecting bars 41 , so as to isolate the crossbeam 20 and the connecting bars 41 , thereby providing comprehensive insulation protection for the connecting bars 41 .

[0045] It can be understood that the battery tray 10 of the present application sets an opening 22 on the crossbeam 20. While not affecting the function of the crossbeam 20 itself, it can also utilize the structure of the crossbeam 20 itself to accommodate the connecting assembly 40 and the insulating sheath 50, so as to reduce the occupied space and improve the space utilization of the battery pack 100, thereby improving the energy density of the battery pack 100 and making the layout inside the battery pack 100 more beautiful.

[0046] Furthermore, along the second direction 002, the insulating sheath 50 has a clamping portion 511 on opposite sides thereof. When the insulating sheath 50 is assembled to the opening 22 of the beam 20, the clamping portion 511 abuts against the top wall 24 of the beam 20, thereby realizing the relative position between the insulating sheath 50 and the beam 20.

[0047] It can be understood that the present application provides a snap-fit ​​portion 511 at the opposite ends of the insulating sheath 50 along the second direction 002, and makes the snap-fit ​​portion 511 abut against the top wall 24 of the beam 20, so as to ensure that the insulating sheath 50 and the beam 20 are reliably fixed, while also simplifying the structure of the insulating sheath 50. The present application provides a snap-fit ​​fixation between the insulating sheath 50 and the beam 20, which is convenient for disassembly and assembly, can reduce the difficulty of assembly, improve assembly efficiency and reduce costs. At the same time, by providing the snap-fit ​​portion 511 at the opposite sides of the insulating sheath 50 along the second direction 002, the space occupied by the insulating sheath 50 can be further reduced, thereby improving the space utilization of the battery tray 10 and further improving the energy density of the battery pack 100.

[0048] It should be noted that in the above embodiment, the two electrical components 30 can be configured as two battery components, and the opposite ends of the connecting component 40 are respectively connected to a battery component to achieve the series or parallel connection of the two battery components. In another embodiment, the two electrical components 30 can also be configured as a battery component and a power distribution component, wherein the power distribution component is used to charge the battery component. The connecting component 40 serves as a transmission channel to transmit the electrical energy of the power distribution component to the battery component. That is, the present application does not specifically limit the specific structure of the electrical component.

[0049] For further information, please refer to Figures 4 to 6 ,in Figure 4 This is a schematic structural diagram of an insulating sheath 50 provided in one embodiment of the present application from one side perspective; Figure 5 This is a schematic diagram of the structure of a base 51 provided in an embodiment of the present application; Figure 6 It is a schematic structural diagram of a protective cover 52 provided in an embodiment of the present application.

[0050] like Figures 1 to 6 As shown, in one embodiment, the insulating sheath 50 includes a base 51 and a protective cover 52. Along the third direction 003, that is, along the direction perpendicular to the plane of the bottom plate 12, the base 51 and the protective cover 52 are located on opposite sides of the connecting row 41. That is, along the third direction 003, the connecting row 41 is located between the base 51 and the protective cover 52. At the same time, the base 51 is fixed to the opening 22, that is, fixed to the bottom of the groove 23. The base 51 includes a groove 53, and the two connecting rows 41 pass through the groove 53 along the first direction 001 after being connected. The groove 53 includes a first side wall 531, and the number of the first side walls 531 is two. The two first side walls 531 are arranged at intervals along the second direction 002, and each engaging portion 511 is arranged on a first side wall 531, and abuts against the top wall 24 of the beam 20 to limit the relative position between the base 51 and the beam 20 in the third direction 003. The protection cover 52 is located at the notch of the groove 53 and is movably connected to the base 51 to cover the groove 53 .

[0051] It can be understood that in this embodiment, the insulating sheath 50 is set as a movably connected base 51 and a protective cover 52 so as to expose the connection areas of the two connection components 40 to achieve a fixed connection between the two connection rows 41, and the protective cover 52 can be covered after the fixed connection is completed to ensure the insulation protection effect of the connection row 41.

[0052] In one embodiment, after the base 51 and the beam 20 are assembled, each engaging portion 511 extends obliquely from the first side wall 531 toward a direction away from the groove 53 and close to the top wall 24 of the beam 20. That is, the engaging portion 511 is configured as a V-shaped elastic buckle.

[0053] It can be understood that in the present embodiment, the locking portion 511 is configured as a V-shaped elastic buckle. When installing the base 51 and the beam 20, the base 51 only needs to be placed above the opening 22 and slide toward the tray body 11 along the third direction 003. The V-shaped elastic buckle of the base 51 is deformed under the support of the top wall 24 of the beam 20 until the V-shaped elastic buckle moves to the bottom of the top wall 24. The V-shaped elastic buckle restores its deformation and contacts and resists the surface of the top wall 24 facing the tray body 11, thereby limiting the relative position between the base 51 and the beam 20 in the third direction 003.

[0054] It can be understood that in this embodiment, the base 51 can be fixed at the opening 22 of the beam 20 in the third direction 003 by using the V-shaped elastic buckle to abut against the top wall 24 of the beam 20. At the same time, the engagement portion 511 cooperates with the beam 20, which is also conducive to the installation and removal of the base 51, making the installation and removal more convenient and quick, and improving the efficiency of assembly and removal.

[0055] In one embodiment, each first side wall 531 is provided with flanges 532 along the width direction of the beam 20, that is, on opposite sides along the first direction 001. The flanges 532 extend along the length direction of the beam 20, that is, along the second direction 002, and the flanges 532 also extend toward the side wall 21 of the beam 20 in a direction away from the groove 53, so as to limit the relative position between the base 51 and the beam 20 in the first direction 001.

[0056] In one embodiment, the surfaces opposite to the two flanges 532 are in contact with the side walls 21 of the beam 20. That is, the two flanges 532 on each first side wall 531 cooperate with each other to clamp the two side walls 21 of the beam 20 along its length direction, that is, the base 51 clamps the beam 20 with two pairs of flanges 532 to limit the relative position between the base 51 and the beam in the first direction 001.

[0057] It can be understood that in this embodiment, by providing the flange 532 on the base 51 to clamp the two side walls 21 of the beam 20 along its width direction, this design makes the base 51 simple in structure, easy to manufacture, and convenient to install, which can reduce costs. During installation and removal, the base 51 can be slid along the third direction 003 at the opening 22 to achieve the fixing and separation of the insulating sheath 50 and the beam 20.

[0058] In one embodiment, along the length direction of the beam 20, that is, along the second direction 002, the surface of the first side wall 531 away from the groove 53 contacts the side wall 21 of the beam 20. That is, the surface of the first side wall 531 away from the groove 53 contacts the surface of the side wall 21 facing the groove 53 along the second direction 002. Or it can be understood that the distance between the outer surfaces of the two first side walls 531 is equal to the length of the opening 22 along the second direction 002. That is, along the second direction 002, the base 51 is just stuck in the opening 22.

[0059] It can be understood that by setting the distance between the outer surfaces of the two first side walls 531 along the second direction 002 to be equal to the length of the opening 22, that is, by matching the design dimensions of the base 51 and the opening 22, the relative position between the base 51 and the beam 20 along the second direction 002 is limited.

[0060] In the above embodiment, the position of the insulating sheath 50 and the beam 20 is limited along the third direction 003 by the contact and abutment between the locking portion 511 and the top wall 24 of the beam 20; the position of the insulating sheath 50 and the beam 20 is limited along the first direction 001 by the two pairs of flanges 532 on the first side wall 531; the position of the insulating sheath 50 and the beam 20 is limited along the second direction 002 by the distance between the two first side walls 531 being equal to the length of the opening 22, so that the insulating sheath 50 can be reliably fixed at the opening 22 of the beam 20. This design is not only simple in structure and low in cost, but also easy to disassemble and assemble while ensuring the reliability of the connection between the insulating sheath 50 and the beam 20.

[0061] In one embodiment, the protective cover 52 is clamped on the base 51. Specifically, along the second direction 002, the protective cover 52 is provided with clamping portions 521 on opposite sides thereof, and each first side wall 531 is provided with a bending wall 533 at one end away from the tray body 11, and the bending wall 533 extends along the first direction 001. The bending wall 533 is also provided with a clamping groove 534. Each clamping portion 521 of the protective cover 52 extends into a clamping groove 534 and abuts against the bending wall 533, so that the protective cover 52 is clamped on the base 51.

[0062] It can be understood that in the above embodiment, by providing the protection cover 52 to be snap-connected to the base 51 , it is convenient to assemble and disassemble the protection cover 52 and the base 51 , so as to facilitate the connection and fixation of the two connection rows 41 at the groove 53 .

[0063] In another embodiment, the bent wall 533 is formed by deforming the flange 532. That is, the two flanges 532 on each first side wall 531 are bent relative to each other along the first direction 001 at the end away from the tray body 11 to form the bent wall 533. And the bent walls 533 of the two flanges 532 extend relative to each other to form a clamping groove 534. Along the second direction 002, the opposite sides of the protective cover 52 are provided with clamping parts 521, which extend into the clamping groove 534 and abut the two bent walls 533, which is also convenient for the disassembly and assembly between the protective cover 52 and the base 51.

[0064] It should be noted that in the above embodiment, the connection method between the protective cover 52 and the base 51 is only used as an exemplary introduction, that is, in other embodiments, the connection method between the protective cover 52 and the base 51 of the present application can be adaptively adjusted according to the actual application scenario. For example, in another embodiment, along the second direction 002, one side of the protective cover 52 is rotatably connected to the base 51, and the other side can be snap-connected with the base 51, which is also conducive to the opening and closing of the protective cover 52 relative to the base 51, so as to facilitate the connection and fixing of the two connection rows 41 at the groove 53.

[0065] In one embodiment, the clamping portion 521 is a U-shaped clamp 522. Along the first direction 001, a resisting portion 523 is respectively provided on two opposite sides of each U-shaped clamp 522. The U-shaped clamp 522 extends into the clamping slot 534, and the two resisting portions 523 are respectively resisted against a bending wall 533, so that the protective cover 52 is reliably fixed to the base 51.
