[0047] In this embodiment, the first sealing gasket and the second sealing gasket 5 can both be set to a ring shape and match the contour shape of the frame body 1. The first sealing gasket is attached to the bottom surface of the frame body 1, and the first sealing gasket will not block the opening of the frame body 1. The bottom plate 2 is attached to the lower surface of the first sealing gasket, so that the first sealing gasket is clamped between the bottom plate 2 and the frame body 1, and the bottom plate 2 and the frame body 1 can be fixed by fasteners such as bolts or screws passing through the first sealing gasket; the second sealing gasket 5 is attached to the top surface of the frame body 1, and the second sealing gasket 5 will not block the opening of the frame body 1.

[0049] Further, in one embodiment, see Figure 1As shown, the frame body 1 may include a frame longitudinal beam 12 and a frame cross beam 13, wherein the frame longitudinal beam 12 and the frame cross beam 13 are connected via an adapter 14, wherein the adapter 14 is disposed at the corner of the frame longitudinal beam 12 and the frame cross beam 13; a third sealing gasket 15 is disposed at the connection between the adapter 14 and the frame longitudinal beam 12 and the frame cross beam 13. In this embodiment, the frame body 1 includes two frame longitudinal beams 12 and two frame cross beams 13, wherein the frame longitudinal beams 12 and the frame cross beams 13 are perpendicular to each other, and the two frame longitudinal beams 12 and the two frame cross beams 13 are parallel to each other, so that the two frame longitudinal beams 12 and the two frame cross beams 13 can be assembled into a square frame body 1. Among them, an adapter 14 is arranged at the connection between each frame longitudinal beam 12 and the frame cross beam 13, that is, four adapters 14 can be arranged at the four corners. At the same time, in this embodiment, when the adapter 14 connects the frame longitudinal beam 12 and the frame cross beam 13, by setting a third sealing gasket 15 at the connection between the adapter 14 and the frame longitudinal beam 12, and setting a third sealing gasket 15 at the connection between the adapter 14 and the frame cross beam 13, a sealed connection between the adapter 14 and the frame longitudinal beam 12 and the frame cross beam 13 can be achieved, thereby ensuring the sealing of the connection of the frame body 1.

[0050] Further, see Figures 5 and 6As shown, in one embodiment, the adapter 14 may include an adapter body 141, one side of the adapter body 141 extends to form a first connecting plate 142, and the other side extends to form a second connecting plate 143, the second connecting plate 143 and the first connecting plate 142 extend in directions away from each other; the first connecting plate 142 is fit-connected to the frame cross beam 13, the second connecting plate 143 is fit-connected to the frame longitudinal beam 12, and the third sealing gasket 15 is sandwiched between one side of the adapter body 141 and the frame cross beam 13, and the third sealing gasket 15 is also sandwiched between the other side of the adapter body 141 and the frame longitudinal beam 12. In this embodiment, the adapter 14 can be a casting, and the first connecting plate 142 and the second connecting plate 143 can be cast integrally with the adapter body 141, the first connecting plate 142 and the second connecting plate 143 are perpendicular to each other, the first connecting plate 142 extends in the direction of the frame cross beam 13, the second connecting plate 143 extends in the direction of the frame longitudinal beam 12, and the first connecting plate 142 is parallel to the frame cross beam 13, the second connecting plate 143 is parallel to the frame longitudinal beam 12, and the first connecting plate 142 can be It is fitted on the inner side of the frame cross beam 13, and the second connecting plate 143 is fitted on the inner side of the frame longitudinal beam 12, wherein one third sealing gasket 15 is clamped between the end face of the frame cross beam 13 and one side of the adapter body 141, and the other third sealing gasket 15 is clamped between the end face of the frame longitudinal beam 12 and the other side of the adapter body 141, the third sealing gasket 15 located at the frame cross beam 13 can be perpendicular to the first connecting plate 142, and the third sealing gasket 15 located at the frame longitudinal beam 12 can be perpendicular to the second connecting plate 143.

[0051] In this embodiment, the first connecting plate 142 and the second connecting plate 143 are added, which are respectively fitted to the frame cross beam 13 and the frame longitudinal beam 12 and then connected by fasteners, so that the connection strength between the adapter 14 and the frame cross beam 13 and the frame longitudinal beam 12 can be enhanced. At the same time, the third sealing gasket 15 is arranged separately from the first connecting plate 142 and the second connecting plate 143, and the fasteners connecting the frame cross beam 13 and the frame longitudinal beam 12 do not need to pass through the third sealing gasket 15. A whole piece of the third sealing gasket 15 is clamped between the frame cross beam 13 and the adapter body 141, and a whole piece of the third sealing gasket 15 is clamped between the frame longitudinal beam 12 and the adapter body 141, so that the sealing performance between the frame cross beam 13, the frame longitudinal beam 12 and the adapter body 141 is improved.

[0052] Further, in one embodiment, see Figure 3 As shown, the frame body 1 is provided with a mounting hole 16, a mounting sleeve 17 is welded in the mounting hole 16, a wire screw sleeve is installed in the mounting sleeve 17, and one end of the mounting sleeve 17 is closed ( Figure 8 and Fig. 9As shown), the frame body 1 is connected to the fastener passing through the bottom plate 2 through the wire screw sleeve in the mounting sleeve 17. In this embodiment, a plurality of mounting holes 16 may be provided on the top and bottom surfaces of the frame body 1, and a mounting sleeve 17 may be welded in each mounting hole 16, wherein one end of the mounting sleeve 17 is closed, and the closed end is located inside the frame body 1, and the unclosed end faces the outside of the frame body 1, and is used to connect with components outside the frame body 1, such as the bottom plate 2 or the top plate 3. At the same time, a thread is provided in the mounting sleeve 17, which can be threadedly connected with the wire screw sleeve, so that the wire screw sleeve is installed in the mounting sleeve 17, and the fastener can be threadedly connected to the wire screw sleeve through the bottom plate 2 to achieve the connection between the bottom plate 2 and the frame body 1, and the fastener can also be threadedly connected to the wire screw sleeve on the top of the frame body 1 through the top plate 3 to achieve the connection between the top plate 3 and the frame body 1. The fasteners may be components such as bolts or screws.

[0053] In this embodiment, a blind hole type mounting sleeve 17 is used for connection at the position where the frame body 1 needs to be connected with fasteners, which can ensure the sealing of the connection between the frame body 1 and the external top plate 3 or bottom plate 2, and further improve the sealing performance of the entire power battery compartment. After the above series of sealing guarantees, the power battery compartment in this embodiment can achieve IP68 level of waterproofing.

[0054] The mounting holes 16 in the present embodiment can be arranged on the frame cross beam 13 and the frame longitudinal beam 12 of the frame body 1. Since the frame cross beam 13 and the frame longitudinal beam 12 can be formed by extrusion of aluminum alloy, if threaded holes are directly arranged on the frame cross beam 13 and the frame longitudinal beam 12 made of aluminum alloy to connect with fasteners, the connection strength of the threaded holes made of aluminum alloy is insufficient and the threaded holes are easily worn. In the present embodiment, a blind hole type mounting sleeve 17 is welded in the mounting hole 16 to ensure a sealed connection between the mounting sleeve 17 and the mounting hole 16. At the same time, a wire screw sleeve is arranged in the mounting sleeve 17 to achieve connection with the fastener. The wire screw sleeve and the mounting sleeve 17 are not easy to wear and will not damage the frame cross beam 13 and the frame longitudinal beam 12 made of aluminum alloy.

[0055] Further, see Figure 7 As shown, in some optional embodiments, the interior of the bottom plate 2 is hollow, and a reinforcing rib 21 is provided inside the bottom plate 2. In this embodiment, in order to ensure the strength of the bottom plate 2 of the power battery compartment and meet the requirements of lightweight, the interior of the bottom plate 2 is hollowed out and a reinforcing rib 21 is provided inside.

[0056] See also Figure 1 and Figure 2As shown, in one embodiment, a top connector 8 is installed on the outer side of the top plate 3, and a foam is sandwiched at the connection between the top connector 8 and the top plate 3. In this embodiment, the foam is sandwiched between the top plate 3 and the top connector 8, and the shape of the foam can match the bottom shape of the top connector 8. The top connector 8 and the top plate 3 can be connected by fasteners such as bolts or screws. By sandwiching the foam at the connection between the top connector 8 and the top plate 3, a sealing effect can be achieved between the top connector 8 and the top plate 3, wherein the top connector 8 is used to connect the sub-beam of the carriage.

[0057] Further, in one embodiment, see Figure 1 and Figure 2 As shown, the frame body 1 is provided with an explosion-proof valve 9 for balancing the pressure difference inside and outside the power battery compartment. Preferably, four explosion-proof valves 9 are provided on each frame longitudinal beam 12, that is, a total of eight explosion-proof valves 9 are provided. When the temperature in the power battery compartment changes, the air expands or compresses in the power battery compartment, and the eight explosion-proof valves 9 provided on the frame body 1 can balance the pressure difference inside and outside the power battery compartment.

[0058] Preferably, since the bottom plate 2 in this embodiment is relatively large, the entire bottom plate 2 can be formed by splicing a plurality of small plates, and friction welding can be used between the small plates.

[0059] Further, see Figure 1 As shown, in one embodiment, the battery receiving cavity 11 may be provided with mutually connected supporting longitudinal beams 6 and supporting cross beams 7, wherein the supporting longitudinal beams 6 connect the frame body 1, the bottom plate 2 and the top plate 3, and the supporting cross beams 7 connect the frame body 1 and the top plate 3.

[0060] Among them, see Figures 10 to 12 As shown, both ends of the supporting longitudinal beam 6 are provided with end mounting interfaces 61, and the end mounting interfaces 61 are used to connect the frame body 1 of the power battery compartment along the longitudinal direction of the supporting longitudinal beam 6; the bottom of the supporting longitudinal beam 6 is provided with a bottom mounting interface 62, and the top is provided with a top mounting interface 63, the bottom mounting interface 62 is used to be installed on the bottom plate 2 of the power battery compartment, and the top mounting interface 63 is used to be installed on the top plate 3 of the power battery compartment; the supporting crossbeam 7 is vertically connected to the supporting longitudinal beam 6, and the top of the supporting crossbeam 7 protrudes to form an abutment platform 71, and the abutment platform 71 is used to connect the top plate 3 of the power battery compartment.

[0061] In this embodiment, when in use, the support crossbeam 7 and the support longitudinal beam 6 are installed in the battery receiving cavity 11 in the frame body 1, the support crossbeam 7 and the support longitudinal beam 6 are perpendicular to each other, and the support crossbeam 7 is preferably connected to the middle position of the support longitudinal beam 6, wherein one support longitudinal beam 6 can be provided in the battery receiving cavity 11, or multiple support longitudinal beams 6 can be provided, and when multiple support longitudinal beams 6 are provided, the multiple support longitudinal beams 6 are parallel to each other and extend longitudinally, and at the same time, two adjacent support longitudinal beams 6 can be connected by the support crossbeam 7. Multiple support crossbeams 7 can also be provided, and the multiple support crossbeams 7 can be provided at intervals in the transverse direction or in the longitudinal direction.

[0062] In this embodiment, vertically connected supporting longitudinal beams 6 and supporting cross beams 7 are provided. The supporting longitudinal beams 6 can be connected to the frame body 1 through the end mounting interfaces 61 at both ends, and connected to the bottom plate 2 of the power battery compartment through the bottom mounting interface 62, and connected to the top plate 3 of the power battery compartment through the top mounting interface 63. At the same time, the supporting cross beam 7 can be abutted and connected to the top plate 3 of the power battery compartment through the abutment platform 71. The frame body 1, the bottom plate 2 and the top plate 3 of the power battery compartment are connected by the vertically crossed supporting longitudinal beams 6 and supporting cross beams 7. The supporting longitudinal beams 6 and the supporting cross beams 7 support each other, and a "cross" plus structure ( Figure 4 As shown), the torsional stiffness of the power battery compartment is effectively improved, and the technical problem that the frame of the parallel truss alone is difficult to meet the high torsional stiffness requirements of the power battery frame in the related art is solved. When two support beams 7 are provided, one of the support beams 7 is provided on the left side of the support longitudinal beam 6, and the other support beam 7 is provided on the right side of the support longitudinal beam 6, and the two support beams 7 are collinear, and the two support beams 7 are connected with the support longitudinal beam 6 to form a cross structure, which can partition the battery receiving cavity 11 in the frame body 1 on the one hand, and improve the torsional stiffness of the frame on the other hand.

[0063] In one embodiment, see Fig.11 As shown, the supporting crossbeams 7 are disposed on opposite sides of the supporting longitudinal beam 6 in the transverse direction, and the supporting crossbeams 7 on both sides of the supporting longitudinal beam 6 are disposed symmetrically. That is, in this embodiment, a supporting crossbeam 7 can be disposed on the left side of the supporting longitudinal beam 6, and a supporting crossbeam 7 can also be disposed on the right side of the supporting longitudinal beam 6. After the supporting crossbeam 7 on the left side is rotated 180° around the center of the supporting longitudinal beam 6, the structure and position of the supporting crossbeam 7 on the right side are overlapped; multiple supporting crossbeams 7 are arranged to have the same structure, so as to realize modular design and improve the commonality rate of parts.

[0064] Further, in one embodiment, see Fig.11As shown, the abutment platform 71 is formed by partially protruding upward from the top of the supporting beam 7, so that the supporting beam 7 forms a recessed area 72 on at least one side of the abutment platform 71. That is, in this embodiment, not the entire top surface of the supporting beam 7 protrudes upward to form the abutment platform 71, but a local position of the top surface of the supporting beam 7 protrudes upward to form the abutment platform 71, and the position of the top surface of the supporting beam 7 with the abutment platform 71 is convex, and the position without the abutment platform 71 is concave, that is, the recessed area 72, wherein the recessed area 72 can be formed on one side (for example, the left side or the right side) of each abutment platform 71, and the recessed area 72 can also be formed on the opposite sides (that is, the left and right sides) of each abutment platform 71, as shown in FIG. Fig.11 As shown, in this embodiment, a recessed area 72 is preferably provided on both the left and right sides of each abutting platform 71. In this embodiment, the abutting platform 71 is formed by a local protrusion, and the recessed area 72 is formed on one side of the abutting platform 71.

[0065] In this embodiment, the raised abutment platform 71 will abut against the top plate 3 of the power battery compartment, and can be connected to the top plate 3 and the sub-beam of the compartment through fasteners, thereby connecting the support beam 7 to the sub-beam, so that the support beam 7 can support the sub-beam and reduce the deformation of the sub-beam. Preferably, the connection between the abutment platform 71 and the recessed area 72 in this embodiment can be connected by an inclined surface, which can avoid stress concentration and enable the support beam 7 to withstand greater pressure.

[0066] Further, see Fig.11As shown, in some embodiments, the supporting crossbeam 7 includes a first crossbeam 73 and a second crossbeam 74 extending in the transverse direction, the first crossbeam 73 and the second crossbeam 74 are connected by a reinforcing rib 75, and the reinforcing rib 75 is connected with the first crossbeam 73 and the second crossbeam 74 to form a triangular structure; the first crossbeam 73 and the second crossbeam 74 are connected to the supporting longitudinal beam 6, and the first crossbeam 73 protrudes in a direction away from the second crossbeam 74 to form the abutment platform 71. Among them, the reinforcing ribs 75 between the first crossbeam 73 and the second crossbeam 74 can be arranged obliquely relative to the first crossbeam 73, and a plurality of reinforcing ribs 75 are arranged between the first crossbeam 73 and the second crossbeam 74, and the inclination directions of two adjacent reinforcing ribs 75 are different, so that the two adjacent reinforcing ribs 75 can form a triangle with the first crossbeam 73, and the two adjacent reinforcing ribs 75 can also form a triangle with the second crossbeam 74. One end of the first crossbeam 73 and the second crossbeam 74 can be connected by an end plate, and are connected to the supporting longitudinal beam 6 together through the end plate. The entire supporting crossbeam 7 can be an aluminum alloy casting, and the supporting longitudinal beam 6 can be an aluminum alloy extruded profile. The supporting crossbeam 7 and the supporting longitudinal beam 6 can be connected together by glue-bolt connection or glue-rivet composite connection, that is, adhesive is set between the joint surfaces of the aluminum alloy extruded profile and the aluminum alloy casting, and then the aluminum alloy extruded profile and the aluminum alloy casting are connected by bolts or rivets. This connection method can minimize the micro-wear and stress concentration at the connection, avoid the loosening problem caused by micro-wear, and further improve the torsional reliability of the power battery compartment.

[0067] In this embodiment, by connecting the first cross beam 73 and the second cross beam 74 with reinforcing ribs 75, hollows 76 can be formed between the reinforcing ribs 75. The arrangement of the hollows 76 can make the supporting cross beam 7 lighter, and the arrangement of the reinforcing ribs 75 can ensure the strength of the entire supporting cross beam 7. The other ends of the first cross beam 73 and the second cross beam 74 can also be connected by an end plate, and connected together to the frame body 1 through the end plate.

[0068] Further, in one embodiment, see Fig.11 As shown, a support column 77 is provided between the first crossbeam 73 and the second crossbeam 74 at a position corresponding to the abutment platform 71, and the support column 77 vertically connects the abutment platform 71 and the second crossbeam 74.

[0072] Furthermore, a colloid is provided between the support crossbeam 7 and the support longitudinal beam 6, and the support crossbeam 7 and the support longitudinal beam 6 are connected by a fastener passing through the colloid.

The support crossbeam 7 and the support longitudinal beam 6 are connected together by a glue-bolt connection or a glue-rivet composite connection, which can avoid the loosening problem caused by micro-motion wear to the greatest extent.

[0073] See also Fig.10 and Fig.11 As shown, the supporting longitudinal beam 6 provided in the embodiment of the present application may include: a longitudinal beam body 64, both ends of which are provided with end mounting interfaces 61, and the end mounting interfaces 61 are used to connect the frame body 1 of the power battery compartment along the longitudinal direction of the longitudinal beam body 64; a bottom mounting interface 62 is provided at the bottom of the longitudinal beam body 64, and the bottom mounting interface 62 is used to be installed on the bottom plate 2 of the power battery compartment; a hollow reinforcing tube 65, and the hollow reinforcing tube 65 is arranged on one side of the longitudinal beam body 64 along the transverse direction of the longitudinal beam body 64.

[0074] Among them, the supporting longitudinal beam 6 in this embodiment is installed in the frame body 1 of the power battery compartment when in use. The frame body 1 encloses a battery receiving cavity 11, and the supporting longitudinal beam 6 is placed in the battery receiving cavity 11. After the supporting longitudinal beam 6 is placed in the battery receiving cavity 11, the battery receiving cavity 11 can be divided into multiple spaces.

When the bottom plate 2 is pulled and deformed in the up and down directions, the longitudinal beam body 64 can generate a pulling force on the bottom plate 2 to resist the deformation of the bottom plate 2; wherein the longitudinal beam body 64 can be provided with a row of bottom mounting interfaces 62 along its longitudinal direction to achieve connection with the bottom plate 2 at various locations in the longitudinal direction; the hollow reinforcing tube 65 is provided on the left or right side of the longitudinal beam body 64, or the hollow reinforcing tube 65 is provided on both sides of the longitudinal beam body 64, and the hollow reinforcing tube 65 can extend along the longitudinal direction of the longitudinal beam body 64.

At the same time, by adding a hollow reinforcing tube 65, the strength of the supporting longitudinal beam 6 can be increased, and the deformation of the supporting longitudinal beam 6 and the bottom plate 2 can be further resisted, thereby solving the technical problem in the related art that the power battery is supported only by the bottom plate 2 of the battery frame, the bottom plate 2 is large, easy to deform, and the supporting strength is weak.

[0076] Preferably, both the end mounting interface 61 and the bottom mounting interface 62 can be bolt mounting holes 16, so that the supporting longitudinal beam 6 and the bottom plate 2 can be connected by bolts, and the supporting longitudinal beam 6 and the frame body 1 can also be connected by bolts.

[0077] Furthermore, in one embodiment, the hollow reinforcement tube 65 is integrally extruded with the longitudinal beam body 64. In this embodiment, the entire supporting longitudinal beam 6 can be integrally extruded with an aluminum alloy. During the extrusion, two hollow reinforcement tubes 65 can be extruded on the left and right sides of the longitudinal beam body 64 to improve the strength of the longitudinal beam body 64. The use of aluminum alloy material can reduce the weight of the supporting longitudinal beam 6. At the same time, by integrally extruding, there is no interface gap between the hollow reinforcement tube 65 and the longitudinal beam body 64, which improves the connection strength between the hollow reinforcement tube 65 and the longitudinal beam body 64, thereby improving the strength of the entire supporting longitudinal beam 6.

[0079] Further, see Fig.10 As shown, in one embodiment, the longitudinal beam body 64 may include a vertical plate 641 and a first longitudinal plate 642 perpendicular to the vertical plate 641, and the first longitudinal plate 642 and the vertical plate 641 both extend longitudinally; the hollow reinforcing tube 65 is arranged at the connection between the vertical plate 641 and the first longitudinal plate 642, and one side of the hollow reinforcing tube 65 is connected to the vertical plate 641, and the other side is connected to the first longitudinal plate 642. In this embodiment, the first longitudinal plate 642 is in a horizontal state, and the vertical plate 641 is in a vertical state. The first longitudinal plate 642 is perpendicular to the vertical plate 641, and the vertical plate 641 is preferably arranged on the center line of the first longitudinal plate 642. The hollow reinforcing tube 65 on the left is arranged at the connection between the left side of the vertical plate 641 and the first longitudinal plate 642, and the hollow reinforcing tube 65 on the right is arranged at the connection between the right side of the vertical plate 641 and the first longitudinal plate 642. Each hollow reinforcing tube 65 is not only connected to the vertical plate 641, but also connected to the first longitudinal plate 642, which can improve the connection strength among the vertical plate 641, the first longitudinal plate 642 and the hollow reinforcing tube 65.

[0080] In this embodiment, the hollow reinforcement tube 65 is preferably surrounded by a first plate 651 and a second plate 652, wherein the first plate 651 is vertically connected to the second plate 652, and the first plate 651 and the second plate 652 both extend longitudinally along the longitudinal beam body 64, and the side of the first plate 651 away from the second plate 652 is integrally connected to the vertical plate 641, and the side of the second plate 652 away from the first plate 651 is integrally connected to the first longitudinal plate 642, so that the first plate 651, the second plate 652, the vertical plate 641 and the first longitudinal plate 642 together form a cavity.

[0081] See also Fig.10 As shown, preferably, the longitudinal beam body 64 also includes a second longitudinal plate 643, the second longitudinal plate 643 and the first longitudinal plate 642 are arranged parallel to the opposite sides of the vertical plate 641, and the second longitudinal plate 643 is provided with a top mounting interface 63, and the top mounting interface 63 is used to be installed on the top plate 3 of the power battery compartment. In this embodiment, the second longitudinal plate 643 is arranged at the top of the vertical plate 641, the first longitudinal plate 642 is arranged at the bottom of the vertical plate 641, and the second longitudinal plate 643 is also perpendicular to the vertical plate 641, so that the longitudinal beam body 64 formed by the first longitudinal plate 642, the second longitudinal plate 643 and the vertical plate 641 is an I-shaped structure, which can improve the bending stiffness of the longitudinal beam body 64. Further, the top mounting interface 63 provided on the second longitudinal plate 643 can also be connected to the top plate 3 of the power battery compartment, so that the force on the top plate 3 can be transmitted through the supporting longitudinal beam 6. The top mounting interface 63 in this embodiment is also preferably a bolt mounting hole 16 provided on the second longitudinal plate 643.

[0082] Further, see Fig.10 and Fig.12 As shown, in some optional embodiments, a cutout 66 is provided at the bottom of the supporting longitudinal beam 6, and the cutout 66 penetrates the longitudinal beam body 64 in the transverse direction of the supporting longitudinal beam 6. The cutout 66 is connected to the gap 78 at the bottom of the supporting cross beam 7, and the cutout 66 is preferably provided at the middle position of the supporting longitudinal beam 6, and the supporting cross beam 7 is also preferably connected to the middle position of the supporting longitudinal beam 6, so that the cutout 66 is just opposite to and connected to the gap 78 in the transverse direction.

[0083] Specifically, in this embodiment, the cutout 66 is provided at the bottom of the longitudinal beam body 64, and the cutout 66 penetrates the longitudinal beam body 64 in the transverse direction of the longitudinal beam body 64. In this embodiment, the cutout 66 can be cut and formed after the longitudinal beam body 64 and the hollow reinforcement tube 65 are manufactured and formed. The cutout 66 is preferably provided at the center of the longitudinal beam body 64, and is arranged symmetrically about the center of the longitudinal beam body 64. The cutout 66 provided at the bottom of the longitudinal beam body 64 can be used for threading, that is, the cutout 66 can be used as a channel for threading the power battery harness and pipeline, and the power battery harness and pipeline are threaded in the cutout 66. The inner wall of the cutout 66 can provide sufficient protection and installation guide boundaries for the harness and pipeline. After optimizing the layout of the power battery, the electrical and pipeline interfaces of the power battery and the related pipeline harness, bracket, etc. can be arranged in the cutout 66, and can be arranged in the transverse direction, effectively avoiding the safety risks that may be caused by the weak parts of the power battery during collision.

[0084] In the related art, the local torsional deformation of the power battery is large, which may cause fatigue failure of some electrical connections, pipeline connections and other interfaces, causing serious safety hazards. In this embodiment, by providing the cutout 66, not only can the power battery harness and pipeline be passed through, but also the power battery harness and pipeline can be protected.

[0085] Further, see Fig.13 As shown, in one embodiment, the top wall of the cutout 66 is flush with the top wall of the hollow reinforcing tube 65, and the top wall of the hollow reinforcing tube 65 is connected to the longitudinal beam body 64. In this embodiment, a hollow reinforcing tube 65 is provided on the left side of the longitudinal beam body 64, and a hollow reinforcing tube 65 is also provided on the right side. When the longitudinal beam body 64 is cut to form the cutout 66, the hollow reinforcing tube 65 is also cut to form a complete cutout 66. The highest point of the cutout 66 is also the inner wall at the top of the hollow reinforcing tube 65. Therefore, after the hollow reinforcing tube 65 is cut, the top wall of the hollow reinforcing tube 65 is also the top wall of the cutout 66, and the top wall of the hollow reinforcing tube 65 is the inner wall of the first plate 651, that is, the hollow reinforcing tube 65 on the left side of the vertical plate 641 is connected to the vertical plate 641 through the first plate 651 at the cutout 66, and the hollow reinforcing tube 65 on the right side of the vertical plate 641 is also connected to the vertical plate 641 through the first plate 651 at the cutout 66. In this embodiment, after the cutout 66 is opened at the bottom of the longitudinal beam body 64, the bottom of the longitudinal beam body 64 will be cut to a certain extent, reducing the strength of the longitudinal beam body 64. In order to solve this problem, the top wall of the cutout 66 and the top wall of the hollow reinforcement tube 65 are set to be flush, and the upper part of the cutout 66 can form a complete wall surface (that is, the surface formed by the connection of the two first plates 651 and the vertical plate 641) to ensure the bending strength of the longitudinal beam body 64.

[0086] Further, see Fig.12As shown, in some optional embodiments, along the longitudinal direction of the longitudinal beam body 64, the angle α between the two ends of the cutout 66 has a value range of 90° to 135°. In this embodiment, the middle part of the inner wall of the cutout 66 is set to a horizontal state, and the inner walls at both ends can be set to an inclined state. The inner wall surfaces 661 at both ends can be either inclined surfaces or arc surfaces. When the inner wall surfaces 661 at both ends are inclined surfaces, the angle α between the two inclined surfaces is preferably controlled to be 90° to 135°. Such a setting can reduce the degree of stress concentration at the sudden change part as much as possible; when the inner wall surfaces 661 at both ends are arc surfaces, the angle α between the tangents of the two arc surfaces is preferably controlled to be 90° to 135°.

[0087] Based on the above technical solution, see Fig.12 As shown, in one embodiment, the two ends of the cutout 66 are set to be arc-shaped, and the radius is 100-150 mm. This embodiment is also the case where the inner wall surface 661 at the two ends of the cutout 66 is set to be an arc surface, and the arc surface at each end is processed into an arc with a radius of 100-150 mm for uniform transition, which can effectively avoid the stress concentration caused by the cutout 66 being under a vertical (i.e., up and down) load.

[0088] Further, see Fig.11 As shown, the end of the supporting longitudinal beam 6 is installed with an end connector 4, wherein one side of the end connector 4 is installed to the end mounting interface 61, and the other side of the end connector 4 is installed to the frame body 1 of the power battery compartment, and each end of the supporting longitudinal beam 6 can be installed with two end connectors 4, one on the left and one on the right, and the end connector 4 can also be an aluminum alloy casting, and the end connector 4 and the supporting longitudinal beam 6 can be connected together by glue-bolt connection or glue-rivet composite connection. The supporting longitudinal beam 6 in this embodiment is connected to the frame body 1 by the end connector 4, thereby improving the connection strength between the supporting longitudinal beam 6 and the frame body 1.

[0089] Furthermore, the power battery compartment in this embodiment can adopt a modular design, that is, the structures of the frame longitudinal beams 12, frame cross beams 13, adapters 14, support longitudinal beams 6, support cross beams 7, mounting sleeves 17, fasteners and other components used in various parts of the power battery compartment are the same, which can maximize the modular design, effectively reduce special parts, and greatly improve the commonality of parts.

[0090] In this embodiment, the frame crossbeam 13 and frame longitudinal beam 12 of the frame body 1 can be made of aluminum alloy extruded profiles, the adapter 14 of the frame body 1 can be made of aluminum alloy castings, the supporting longitudinal beam 6 can be made of aluminum alloy extruded profiles, and the supporting crossbeam 7 can be made of aluminum alloy castings. When connecting the aluminum alloy extruded profiles and the aluminum alloy castings, it is preferred to use glue-bolt connection or glue-rivet composite connection to install and connect the components together, that is, set adhesive between the joint surface of the aluminum alloy extruded profile and the aluminum alloy casting, and then connect the aluminum alloy extruded profile and the aluminum alloy casting by bolts or rivets. This connection method can avoid the loosening problem caused by micro-motion wear to the greatest extent. The various parts of the power battery compartment mostly adopt aluminum alloy extrusion and casting technology, which is mature and controllable, with a high yield rate, and there are no difficult operating points in the machining area of ​​all parts, and the machining accuracy is easy to ensure; based on the large-scale use of extruded profiles, the dimensional accuracy of the power battery compartment is easy to be guaranteed, and the machining surface accuracy of the casting parts is high, which can also better ensure the dimensional accuracy of the frame layout. By optimizing the material formula of aluminum alloy extrusion profiles and castings for power battery compartments, the strength of the parts and material elongation can be effectively improved, the density of the parts structure can be enhanced, and thus the mechanical properties of the parts can be improved.

[0091] The power battery compartment of the present application can be designed with all-aluminum alloy, and the layout of the power battery and the compartment body are integrated, adopting the CTC (Cell to Chassis) / MTC (Module to Chassis) layout, which effectively improves the comprehensive energy density of the battery and increases the cruising range of the whole vehicle.

The power battery compartment can be adaptively changed according to the wheelbase of the whole vehicle, the power battery power demand, etc. It has a compact structure, reasonable layout, balanced load distribution, strong layout tolerance of the power battery, and novel shape.
