Description

Technical Field

[0001] The present application belongs to the field of battery pack technology, and specifically, relates to a protective structure beam, a battery pack frame, a battery pack and electrical equipment. Background Art

[0002] At present, the side column collision of the whole vehicle mainly relies on the strength of the vehicle body to cope with it; and as the requirements for the range of electric vehicles continue to increase, the battery power is constantly increasing, and the battery pack is getting bigger and bigger, making the battery pack box closer and closer to the side of the vehicle body; therefore, when a side column collision occurs, the collision will cause the battery pack box to deform and directly press the battery cells inside the module, which may cause fire and explosion. At present, in order to improve the strength of the battery pack box, an energy absorption device is generally added to the battery pack box to buffer the collision, but the setting of the energy absorption device needs to occupy the internal space of the battery pack box, which reduces the volume utilization of the battery pack.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] like Figure 1-4 As shown, a protective structural beam is provided in this embodiment, including a structural beam body 1 and a plurality of mounting parts 2, wherein the plurality of mounting parts 2 are arranged on the side surface of the structural beam body 1 along the length direction of the structural beam body 1; one side of the mounting part 2 is connected to the structural beam body 1, and the other side of the mounting part 2 is extended toward the outside.

[0043] In some embodiments, the mounting portion 2 and the structural beam body 1 are formed as an integral structure, so as to improve the overall stress-bearing performance of the protective structural beam.

[0044] In some embodiments, a plurality of mounting connection holes 21 are provided on the mounting portion 2, and the mounting connection holes 21 can be used for the installation of a connecting sleeve, so that the protective structure beam can be installed and fixed on the external equipment by installing the connecting sleeve.

[0045] Among them, a plurality of collapse holes are also arranged between the structural beam body 1 and the mounting connection hole 21 .

[0046] By arranging the collapse hole between the structural beam body 1 and the mounting connection hole 21, when a side collision occurs, the collision force will be transmitted from the outer side of the mounting portion 2 to the area where the collapse hole is located, so that the collision force is buffered and absorbed by the deformation of the collapse hole, reducing the impact of the collision force on the inner side of the structural beam body 1, thereby improving application safety.

[0047] As one application example, the mounting portion 2 includes a top side surface 22 and a bottom side surface 23, and the top side surface 22 and the bottom side surface 23 are spaced apart to form a buffer inner cavity 3. The buffer inner cavity 3 can provide more deformation space to reduce the impact caused by a side collision.

[0048] In some embodiments, a middle connecting rib 24 is disposed between the top side surface 22 and the bottom side surface 23; wherein the top side surface 22 and the bottom side surface 23 are disposed parallel to each other, and the middle connecting rib 24 is vertically connected between the top side surface 22 and the bottom side surface 23. Figure 1 , 3 shown.

[0049] At this time, the middle connecting rib 24 divides the buffer inner cavity 3 into an outer buffer cavity 31 and an inner buffer cavity 32 , the mounting connecting hole 21 is arranged on the outer buffer cavity 31 , and the collapse hole is arranged on the inner buffer cavity 32 .

[0050] By providing the middle connecting rib 24, the structural strength of the mounting portion 2 can be improved, thereby realizing the mounting installation application of the mounting portion 2 and the protective structure beam.

[0051] As an application example, the collapse hole includes a first collapse hole 41 , and the first collapse hole 41 penetrates from the top side surface 22 to the bottom side surface 23 .

[0052] By setting the first collapse hole 41 and setting the first collapse hole 41 in a through-setting form, a main collapse deformation area can be formed based on the setting of the first collapse hole 41 to cope with the side collision force.

[0053] As one application example, reinforcing ribs 25 respectively connecting the top side 22 and the bottom side 23 are further provided in the inner buffer cavity 32; by setting the reinforcing ribs 25, it is convenient to improve the force strength of the mounting part 2 and the structural beam body 1 to meet the application of the protective structural beam under higher weight requirements.

[0054] In some embodiments, the collapse hole further includes a plurality of notches 42 formed on the reinforcing rib 24. The notches 42 may be pre-designed when the mounting portion 2 is formed; or, may be formed by shearing after forming.

[0055] By forming the notch 42, it is possible to balance the overall stress strength and the shrinkage effect of the protective structure beam. On the basis of achieving the preset shrinkage effect, the size of the first shrinkage hole 41 can be set smaller, thereby avoiding the setting of the shrinkage area from affecting the overall strength of the protective structure beam.

[0056] As one application example, the mounting portion 2 is further provided with a middle barrier surface 26, and the middle barrier surface 26 is arranged between the top side surface 22 and the bottom side surface 23 at intervals. At this time, the top side surface 22, the middle barrier surface 26 and the bottom side surface 23 are arranged parallel to each other. Figure 3 shown.

[0057] In some embodiments, the middle connecting rib 24 and the reinforcing rib 25 are disposed between the top side surface 22 and the middle barrier surface 26 and between the bottom side surface 23 and the middle barrier surface 26 ; the notches 42 are symmetrically disposed on the reinforcing rib 25 on both sides of the middle barrier surface 26 .

[0058] By setting the middle barrier surface 26, the overall force-bearing strength of the protective structure beam can be further improved; and by symmetrically setting the notches 42 on both sides of the middle barrier surface 26, it is possible to facilitate the realization of collapse deformation when the collision force acts on the area where the collapse hole is located in the event of a lateral collision, thereby achieving a buffering and energy-absorbing effect.

[0059] As an application example, the collapse hole further includes a second collapse hole 43 , and the second collapse hole 43 is disposed through the top side surface 22 and / or the bottom side surface 23 .

[0060] In some embodiments, the second collapse hole 43 is disposed through the top side surface 22 and communicates with the notch 42 located above the middle barrier surface 26 .

[0061] In some embodiments, the second collapse hole 43 is disposed through the bottom side surface 23 and communicates with the notch 42 located below the middle barrier surface 26 .

[0062] By setting the second collapse hole 43, it is possible to better balance the overall stress strength and the collapse effect of the protective structure beam, and the size of the first collapse hole 41 can be made smaller, thereby further improving the application effect.

[0063] As an application example, the first shrinkage hole 41 and / or the second shrinkage hole 43 is overlapped with the reinforcing rib 25 .

[0064] In some embodiments, when the first collapse hole 41 overlaps with the reinforcing rib 25 , the first collapse hole 41 cuts off the reinforcing rib 25 .

[0065] In some embodiments, when the second collapse hole 43 overlaps with the reinforcing rib 25 , the second collapse hole 43 is communicated with the corresponding notch 42 ; at this time, the reinforcing rib 25 is still retained on both sides of the middle barrier surface 26 .

[0066] By designing the arrangement positions between the first collapse hole 41 and the reinforcing rib 25 and between the second collapse hole 43 and the reinforcing rib 25 , it is possible to further balance the overall stress strength and collapse effect of the protective structure beam.

[0067] In addition, if Figure 4 As shown, the present embodiment also provides a battery pack frame, on which the protective structural beam as described above is provided; for example, the side beams on the left and right sides of the battery pack frame are both set as the protective structural beams.

[0068] By applying the protective structure beam provided in this embodiment to the battery pack frame, when a lateral collision occurs, the collision force can be buffered and absorbed in the area where the collapse hole is located, thereby reducing the impact of the lateral collision on the interior of the battery pack frame and improving application safety.

[0069] On the other hand, this embodiment also provides a battery pack, in which the battery pack frame as described above is disposed.

[0070] By applying the battery pack frame provided in the present embodiment in the battery pack, it is possible to buffer and absorb the force of a lateral collision on the battery pack frame, thereby reducing or even avoiding the need to provide an energy-absorbing device inside the battery pack, thereby facilitating improving the volume utilization of the battery pack and achieving a larger battery capacity layout.

[0071] On the other hand, the present embodiment also provides an electrical device, in which the battery pack frame or battery pack as described above is disposed.

[0072] In some embodiments, the electrical device may be configured as a transportation vehicle such as a car.

[0073] By applying the battery pack frame or battery pack provided in this embodiment to the electrical equipment, it is possible to reduce the impact caused by a side collision and improve the application safety of the electrical equipment; it is also possible to improve the volume utilization rate within the electrical equipment and achieve a higher battery power layout to meet higher endurance requirements.
