[0003] The purpose of the present disclosure is to provide a vehicle to solve the problem in the related art that when an electric vehicle is hit from the side, the door sill is deformed by the force and squeezes the battery pack mounted on the frame, causing damage to the battery pack.

[0004] A first object of the present disclosure is to provide a vehicle, the vehicle comprising an energy absorbing structure, a door sill and a battery pack, the energy absorbing structure being arranged in a gap between the battery pack and the door sill and being connected to the door sill and the battery pack respectively, the energy absorbing structure comprising:

[0005] A first buffer portion, located on a side of the energy absorbing structure facing the door sill, extending along a first direction, and having a first cavity extending along the first direction formed therein, the first buffer portion being used to absorb stress from the door sill in a second direction;

[0006] a second buffer portion, located on a side of the energy absorbing structure facing the battery pack, disposed on a side of the first buffer portion and extending along the first direction, for absorbing stress from the first buffer portion to increase the bending resistance of the first buffer portion in the first direction, a second cavity extending along the first direction is provided inside the second buffer portion, a first reinforcing rib extending along the first direction is provided in the second cavity, and the stress in the second direction is at least partially absorbed by the first reinforcing rib and dispersed in the first direction along the first reinforcing rib;

[0007] The first direction is parallel to the length direction of the threshold, and the second direction is parallel to the width direction of the threshold.

[0008] Optionally, the energy absorbing structure further includes a reinforcing portion, which is arranged on a side of the second buffer portion away from the first buffer portion and extends along the first direction, and is used for absorbing stress from the second buffer portion to increase the bending resistance of the second buffer portion in the first direction.

[0009] Optionally, a third cavity is opened inside the reinforcement part, and the third cavity extends to both ends of the reinforcement part in the first direction. Second reinforcement ribs are arranged in the third cavity, and the second reinforcement ribs extend to both ends of the third cavity in the first direction.

[0010] Optionally, a third reinforcing rib is disposed in the first cavity, and the third reinforcing rib is inclined relative to a plane formed by the first direction and the second direction.

[0011] Optionally, the second buffer portion is configured in a plate shape, and a connecting side surface of the second buffer portion is orthogonal to the second direction.

[0012] Optionally, the reinforcement portion is plate-shaped and is vertically disposed on a connecting side surface of the second buffer portion that is away from the first buffer portion.

[0013] Optionally, the vehicle further includes a door sill and a battery pack, and the energy absorbing structure is disposed between the battery pack and the door sill and is connected to the door sill and the battery pack respectively.

[0014] Optionally, the vehicle further includes a frame and a mounting longitudinal beam, the door sill is connected to the frame, and the battery pack is connected to the frame via the mounting longitudinal beam, wherein the door sill and the battery pack respectively extend along the first direction and are arranged at intervals in the second direction, wherein a mounting portion extending along the first direction is provided on the battery pack, and the second buffer portion is at least partially clamped between the mounting longitudinal beam and the mounting portion.

[0015] Optionally, the vehicle further includes a frame and a mounting longitudinal beam, the door sill is connected to the frame, and the battery pack is connected to the frame via the mounting longitudinal beam, wherein the door sill and the battery pack respectively extend along the first direction and are arranged at intervals in the second direction, wherein a mounting portion extending along the first direction is provided on the battery pack, and the reinforcing portion is at least partially clamped between the mounting longitudinal beam and the mounting portion.

[0016] Optionally, the energy absorbing structure is connected to the mounting longitudinal beam and the battery pack by fasteners that pass through the mounting longitudinal beam, the energy absorbing structure and the mounting portion in sequence.

[0017] Optionally, the vehicle further comprises a plurality of connecting members constructed in a plate shape, two ends of the connecting members are respectively connected to the door sill and the first buffer portion, and in the first direction, the plurality of connecting members are arranged at intervals.

[0018] Through the above technical solution, when the energy absorbing structure is impacted in the second direction, the area in the first buffer portion where the first cavity is provided will collapse and deform when subjected to stress in the second direction to absorb the stress from the second direction. During the deformation of the first buffer portion, the outer peripheral surface of the first buffer portion will be subjected to stress, and the inner side surface of the first buffer portion, i.e., the cavity wall surface of the first cavity, will also be subjected to stress, so that the stress in the second direction will be dispersed to the two surfaces at the same time, and the first buffer portion can be fully deformed to deform as much as possible to absorb the stress, and at the same time, the stress can be dispersed and the stress distribution can be made more uniform. The stress absorbed by the second buffer portion from the first buffer portion will be dispersed in the first direction along the extension track of the first reinforcing rib, and the stress from the second direction received by the energy absorbing structure will be further dispersed to the first direction, avoiding excessive concentration of stress on the energy absorbing structure, making the stress more stable, and reducing the bending of the energy absorbing structure in the second direction. When the vehicle is impacted from the side of the vehicle and the energy absorbing structure is applied to the side of the vehicle, the length direction of the door sill is the length direction of the vehicle, and the width direction of the door sill is the width direction of the vehicle. The energy-absorbing structure is arranged in the gap between the battery pack and the door sill. When the door sill is deformed, the door sill will not directly squeeze the battery pack. The energy-absorbing structure can absorb stress in the first place to ensure the energy-absorbing efficiency of the energy-absorbing structure. At the same time, the energy-absorbing structure can support the door sill when the door sill is deformed to prevent the door sill from deforming. When the deformed door sill squeezes the energy-absorbing structure, the first buffer part in the energy-absorbing structure will be fully deformed to absorb the stress in the second direction. The second buffer part can stabilize the first buffer part as much as possible and disperse the stress in the second direction. In this way, the energy-absorbing structure will be fully deformed to absorb the stress but will not bend too much. The energy-absorbing structure will not squeeze the battery pack due to bending, and the battery pack will not endanger the vehicle and personal safety due to large deformation.

DETAILED DESCRIPTION

[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, the directional words used generally refer to the relevant parts under normal use. "Inside and outside" can refer to the inside and outside of the outline of the corresponding part or its location inside or outside the environment, depending on the specific context. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order or importance.

[0029] In an electric vehicle, the battery pack 6 is usually mounted on the frame of the electric vehicle and is located under the seat and between the front and rear wheels. When the electric vehicle is hit from the side of the vehicle, the door sill 4 on the side of the vehicle will be subjected to the impact force in the width direction of the vehicle and deform. The deformed door sill 4 will squeeze the battery pack 6 mounted on the frame, and the battery pack 6 will be deformed by force. When the deformation degree of the door sill 4 is large, the battery pack 6 will also be greatly deformed due to the squeezing of the door sill 4, thereby endangering the safety of the vehicle and people.

[0030] like Figure 1 and Figure 2As shown, the present disclosure provides a vehicle, the vehicle includes an energy absorbing structure, a door sill 4 and a battery pack 6, the energy absorbing structure is arranged in the interval between the battery pack 6 and the door sill 4 and connected to the door sill 4 and the battery pack 6 respectively, the energy absorbing structure includes a first buffer portion 1 and a second buffer portion 2, wherein the first buffer portion 1 is located on the side of the energy absorbing structure facing the door sill 4, extends along the first direction, and has a first cavity 11 extending along the first direction opened inside, the first buffer portion 1 is used to absorb stress from the door sill 4 in the second direction; the second buffer portion 2 is located on the side of the energy absorbing structure facing the battery pack 6, is arranged on the side of the first buffer portion 1 and extends along the first direction, and is used to absorb stress from the first buffer portion 1 to increase the bending resistance of the first buffer portion 1 in the first direction, the second buffer portion 2 has a second cavity 21 extending along the first direction opened inside, a first reinforcing rib 22 extending along the first direction is arranged in the second cavity 21, and the stress in the second direction is at least partially absorbed by the first reinforcing rib 22 and dispersed in the first direction along the first reinforcing rib 22. The first direction is parallel to the length direction of the door sill 4, and the second direction is parallel to the width direction of the door sill 4.

[0031] Through the above technical solution, when the energy absorbing structure is impacted in the second direction, the area of ​​the first buffer portion 1 in which the first cavity 11 is provided will collapse and deform when subjected to stress in the second direction to absorb the stress from the second direction. During the deformation of the first buffer portion 1, the outer peripheral surface of the first buffer portion 1 will be subjected to stress, and the inner side surface of the first buffer portion 1, i.e., the cavity wall surface of the first cavity 11, will also be subjected to stress, so that the stress in the second direction will be dispersed to the two surfaces at the same time, and the first buffer portion 1 can be fully deformed to deform as much as possible to absorb stress, and at the same time, the stress can be dispersed and the stress distribution can be made more uniform. The stress absorbed by the second buffer portion 2 from the first buffer portion 1 will be dispersed in the first direction along the extension track of the first reinforcing rib 22, and the stress from the second direction received by the energy absorbing structure will be further dispersed to the first direction, avoiding excessive concentration of stress on the energy absorbing structure, making the stress more stable, and reducing the bending of the energy absorbing structure in the second direction. When the vehicle is impacted from the side of the vehicle and the energy absorbing structure is applied to the side of the vehicle, the length direction of the door sill 4 is the length direction of the vehicle, and the width direction of the door sill 4 is the width direction of the vehicle. The energy absorbing structure is arranged in the interval between the battery pack 6 and the door sill 4. When the door sill 4 is deformed, the door sill 4 will not directly squeeze the battery pack 6. The energy absorbing structure can absorb stress in the first time to ensure the energy absorbing efficiency of the energy absorbing structure. At the same time, the energy absorbing structure can support the door sill 4 when the door sill 4 is deformed to prevent the door sill 4 from deforming. When the deformed door sill 4 squeezes the energy absorbing structure, the first buffer part 1 in the energy absorbing structure will be fully deformed to absorb the stress in the second direction. The second buffer part can stabilize the first buffer part as much as possible and disperse the stress in the second direction. In this way, the energy absorbing structure will be fully deformed to absorb the stress but will not bend too much. The energy absorbing structure will not squeeze the battery pack 6 due to bending, and the battery pack 6 will not endanger the vehicle and personal safety due to large deformation.

[0032] The energy-absorbing structure may also include a reinforcement portion, which is arranged on a side of the second buffer portion 2 away from the first buffer portion 1 and extends along the first direction, and is used to absorb stress from the second buffer portion 2 to increase the bending resistance of the second buffer portion 2 in the first direction. The cross section of the reinforcement portion 3 in the second direction will be connected to the cross section of the second buffer portion 2 in the second direction as a whole. The reinforcement portion 3 increases the cross-sectional area of ​​the second buffer portion 2 in the second direction in disguised form, thereby improving the ability of the second buffer portion 2 to resist bending moments, and further improves the ability of the first buffer portion 1 to resist bending moments in disguised form. The reinforcement portion 3 can assist the second buffer portion 2 to further reduce the bending of the energy-absorbing structure in the second direction. That is, the reinforcement portion 3 improves the overall deformation stability of the energy-absorbing structure, and can effectively prevent the energy-absorbing structure from deflecting itself when in use, so that the deformation stability of the energy-absorbing structure is better.

[0033] In some embodiments, the reinforcement part 3 can also disperse the stress in the first direction. In this case, a third cavity 31 can be opened inside the reinforcement part 3. The third cavity 31 extends to both ends of the reinforcement part 3 in the first direction. A second reinforcing rib 32 is arranged in the third cavity 31. The second reinforcing rib 32 extends to both ends of the third cavity 31 in the first direction. When the reinforcement part 3 is subjected to the stress transmitted from the second direction, the third cavity 31 can also disperse the stress more evenly like the first cavity 11. The extension of the third cavity 31 to both ends of the reinforcement part 3 in the first direction increases the extension length of the third cavity 31, ensuring that the third cavity 31 has a more even stress distribution effect. At the same time, the third cavity 31 with a sufficient extension length can also be provided with a sufficiently long second reinforcing rib 32, so that the stress is dispersed farther in the first direction.

[0034] When the energy-absorbing structure absorbs the stress in the second direction, it will deform, which will cause part of the stress in the second direction to be dispersed toward other directions, that is, part of the stress will be dispersed to the third direction that is orthogonal to the first direction and the second direction respectively. When the vehicle is hit from the side of the vehicle and the energy-absorbing structure is applied to the side of the vehicle, the third direction here is the height direction of the vehicle. For the energy-absorbing structure, the stress in the third direction is the stress that can cause the energy-absorbing structure to deflect. When the stress in the third direction is too large, the position of the energy-absorbing structure will change or directly detach, affecting the effect of the energy-absorbing structure in resisting the impact. Therefore, in some embodiments, a third reinforcing rib 12 is provided in the first cavity 11, and the third reinforcing rib 12 is inclined relative to the plane formed by the first direction and the second direction. In this way, the extension direction of the third reinforcing rib 12 can be inclined to the first direction, the second direction and the third direction at the same time, so that the stress in the third direction is at least partially absorbed by the third reinforcing rib 12 and dispersed along the third reinforcing rib 12. That is, the stress in the third direction will also be further dispersed to the direction that is inclined to the first direction, the second direction and the third direction at the same time, preventing the energy-absorbing structure from deflecting. The first cavity 11 may also extend to both ends of the second buffer portion 2 in the first direction, like the third cavity 31 , and the third reinforcing rib 12 may also extend to both ends of the first cavity 11 in the first direction.

[0035] The second buffer portion 2 may be plate-shaped, and the connecting side surface of the second buffer portion 2 is orthogonal to the second direction. The connecting side surface of the second buffer portion 2 may be the surface with the largest area in the second buffer portion 2, so that the stress absorbed by the second buffer portion 2 can be dispersed to a larger range, avoiding the risk of bending and cracking of the second buffer portion 2 due to excessive local stress.

[0036] Further, the reinforcing portion 3 may also be configured in a plate shape, and the reinforcing portion 3 is vertically arranged on the connecting side of the second buffer portion 2 away from the first buffer portion 1. The reinforcing portion 3 is vertically arranged on the connecting side of the second buffer portion 2, which may mean that the surface with the largest area in the reinforcing portion 3 extends along the first direction and can be vertically arranged on the connecting side of the second buffer portion 2 away from the first buffer portion 1, thereby increasing the cross-sectional area of ​​the second buffer portion 2 in the second direction as much as possible, and maximizing the ability of the first buffer portion 1 to resist bending moment.

[0037] In some embodiments, the vehicle may further include a frame and a mounting longitudinal beam 5, a door sill 4 is connected to the frame, and a battery pack 6 is connected to the frame through the mounting longitudinal beam 5, wherein the door sill 4 and the battery pack 6 respectively extend in a first direction and are spaced apart in a second direction, a mounting portion 61 extending in the first direction is provided on the battery pack 6, and the second buffer portion 2 is at least partially clamped between the mounting longitudinal beam 5 and the mounting portion 61. When the energy absorbing structure is provided with the reinforcement portion 3 described above, the reinforcement portion 3 may also be at least partially clamped between the mounting longitudinal beam 5 and the mounting portion 61. The second buffer portion 2 or the reinforcement portion 3 in the energy absorbing structure is clamped between the mounting longitudinal beam 5 and the mounting portion 61, so that the energy absorbing structure can be connected to the mounting longitudinal beam 5 and the battery pack 6 by sequentially passing through the fasteners 8 of the mounting longitudinal beam 5, the second buffer portion 2 or the reinforcement portion 3 and the mounting portion 61. Figure 3 For example, at this time, the fastener 8 is sequentially passed through the mounting longitudinal beam 5, the reinforcement portion 3 and the mounting portion 61. In this way, the energy absorbing structure is at least partially clamped between the mounting longitudinal beam 5 and the mounting portion 61. The mounting longitudinal beam 5 and the mounting portion 61 can fix the energy absorbing structure by fixing the second buffer portion 2 or the reinforcement portion 3. At the same time, the space occupied by the energy absorbing structure in the width direction of the vehicle is reduced. The mounting longitudinal beam 5 and the mounting portion 61 extend in the first direction respectively, and the energy absorbing structure is indirectly connected to the frame through the mounting longitudinal beam 5. In this way, the energy absorbing structure will be more stable and less likely to deflect in the third direction, that is, the energy absorbing structure is not likely to flip upward and deform after being impacted by a side collision, thereby avoiding the battery being squeezed by the battery pack frame. A plurality of fasteners 8 can be arranged at intervals in the first direction to ensure the connection strength between the mounting portion 61 and the mounting longitudinal beam 5, and also ensure the connection strength between the energy absorbing structure and the mounting portion 61 and the mounting longitudinal beam 5.

[0038] In the first direction, the length of the first buffer portion 1 may be greater than or equal to the length of the mounting longitudinal beam 5. In this way, the first buffer portion 1 may cover the connection between the battery pack 6 and the frame as much as possible in the first direction, thereby preventing the battery pack 6 from falling due to excessive squeezing of the connection between the battery pack 6 and the frame, thereby causing secondary damage to the battery pack 6. At the same time, in the first direction, the length of the second buffer portion 2 may be greater than or equal to the length of the mounting longitudinal beam 5. In this way, the length of the second buffer portion 2 can cover the first buffer portion 1 as much as possible, thereby ensuring the effect of the second buffer portion 2 in increasing the resistance of the first buffer portion 1 to bending moment.

[0039] The vehicle may further include a plurality of plate-shaped connecting members 7, the two ends of which are respectively connected to the door sill 4 and the first buffer portion 1, and the plurality of connecting members 7 are arranged at intervals in the first direction. Figure 4 The threshold 4 can fix the first buffer part 1 through the connecting member 7, the threshold 4 and the energy absorbing structure can be connected to each other, and the threshold 4 can further fix the energy absorbing structure, so that the energy absorbing structure will be more stable. At the same time, the connecting member 7 constructed in a plate shape can save more space while ensuring the connection effect, reducing the space occupied by the connecting member 7. In some embodiments, the connecting member 7 can be connected to the first buffer part 1 through rivets, and the connecting member 7 is connected to the threshold 4 through bolts.

[0040] When the electric vehicle is hit from the side, during the collision, the door sill 4 will be subjected to the impact force in the width direction of the vehicle and deform. When the door sill begins to deform, the energy absorption structure, including the first buffer portion 1 and the second buffer portion 2, can support the door sill 4 to prevent the door sill 4 from flipping when it has not yet completely deformed and absorbed energy. During the deformation of the door sill 4, the first buffer portion 1 and the second buffer portion 2 can participate in the deformation to absorb the stress on the door sill 4 and disperse the stress. The reinforcement portion 3 in the energy absorption structure can be clamped between the mounting longitudinal beam 5 and the mounting portion 61 of the battery pack 6. After being fixed, the reinforcement portion 3 can prevent the energy absorption structure from flipping itself and squeezing the battery pack 6. The energy absorption structure is connected to the door sill 4 through the connecting member 7. At this time, the fixed reinforcement portion 3 can also prevent the door sill 4 from flipping and squeezing the battery pack 6. At the same time, under the action of absorbing the stress on the door sill 4 and dispersing the stress of the energy absorption structure, the flipping of the mounting longitudinal beam 5 and the flipping of the frame of the battery pack 6 are reduced, thereby preventing the battery pack 6 from being squeezed by the mounting longitudinal beam 5 and the frame of the battery pack 6.
