[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Reference below Figure 1-Figure 10 A battery pack installation structure 100 according to an embodiment of the utility model is described. The battery pack installation structure 100 includes a floor 1, a battery pack 2 and a support beam 15. The battery pack 2 is assembled on the floor 1. The floor 1 includes a first cross beam 11, a second cross beam 12 and two threshold beams 14. The first cross beam 11 and the second cross beam 12 are arranged opposite to and spaced apart along the length direction of the floor 1. The first cross beam 11 and the second cross beam 12 are both connected between the two threshold beams 14. The battery pack 2 has at least one longitudinal beam frame 21. The longitudinal beam frame 21 is connected between the first cross beam 11 and the second cross beam 12. In the width direction of the floor 1, the support beam 15 is arranged between the corresponding threshold beam 14 and the battery pack 2.

[0041] The longitudinal beam skeleton 21 of the battery pack 2 is configured as the longitudinal beam of the floor, and the support beam 15 is supported on the corresponding door sill beam 14 and the battery pack 2, so as to improve the structural strength of the battery pack installation structure 100, so that the vehicle with the battery pack installation structure 100 can achieve lightweight design and reduce costs.

[0042] In some embodiments, the battery pack 2 can be used to provide electrical energy for the vehicle. For example, the battery pack 2 provides electrical energy for a motor that drives the vehicle, so that the vehicle can be constructed as a pure electric vehicle or a hybrid vehicle (for example, a hybrid electric vehicle). In addition, the battery pack 2 can also provide electrical energy for the vehicle's electrical equipment (such as air conditioning, etc.).

[0043] like Figure 2 and Figure 4 As shown, in some embodiments, along the length direction of the battery pack mounting structure 100 (i.e., the X direction shown in the figure), the first cross beam 11 can be a cabin rear cross beam of the battery pack mounting structure 100, and the second cross beam 12 can be a rear floor front cross beam of the battery pack mounting structure 100. In the length direction of the battery pack mounting structure 100, the first cross beam 11 is located in front of the second cross beam 12, and the first cross beam 11 and the second cross beam 12 are opposite to each other and spaced apart.

[0044] The battery pack 2 has a longitudinal beam frame 21, and when the battery pack 2 is assembled on the floor 1, one end of the longitudinal beam frame 21 is suitable for being fixedly connected to the first cross beam 11, and the other end of the longitudinal beam frame 21 is suitable for being fixedly connected to the second cross beam 12, so that in the length direction of the battery pack mounting structure 100, the longitudinal beam frame 21 is fixedly connected between the first cross beam 11 and the second cross beam 12. The longitudinal beam frame 21 can transfer the force between the first cross beam 11 and the second cross beam 12 to avoid the risk of stress concentration in one of the first cross beam 11 and the second cross beam 12. For example, during the collision of the battery pack mounting structure 100, the force generated by the collision can be effectively transferred to reduce the risk of excessive deformation of the floor 1. At the same time, such an arrangement also enables the longitudinal beam frame 21 to be configured as a longitudinal beam of the floor 1, which can not only ensure the structural strength of the floor 1, but also reduce the overall mass of the floor 1, thereby realizing a lightweight design of the battery pack mounting structure 100.

[0045] Combination Figure 5 and Figure 6 As shown, in some embodiments, the floor 1 also includes a bottom plate member 13, which is connected between the first cross beam 11 and the second cross beam 12, and can limit the relative position of the first cross beam 11 and the second cross beam 12 to improve the structural strength of the floor 1. In addition, since the first cross beam 11 and the second cross beam 12 are connected with the bottom plate member 13, when the battery pack 2 is detached from the floor 1, the floor 1 can still have a certain structural strength.

[0046] Combination Figure 4 and Figure 8 As shown, in some embodiments of the present invention, the battery pack 2 is provided with two longitudinal beam frames 21 as an example for explanation, and the two longitudinal beam frames 21 are respectively located on both sides of the battery pack 2. When the battery pack 2 is assembled on the floor 1, the two longitudinal beam frames 21 are connected between the first cross beam 11 and the second cross beam 12, so that they are respectively configured as two longitudinal beams of the floor 1, thereby improving the overall structural strength of the floor 1. It should be supplemented that, in some embodiments of the present invention, the battery pack 2 is provided with two longitudinal beam frames 21 as an example, but the present invention is not limited thereto, and the number of longitudinal beam frames 21 provided by the battery pack 2 can be set according to specific conditions, for example, the number of longitudinal beam frames 21 provided by the battery pack 2 can be one, three, four, five, etc.

[0047] In addition, since the longitudinal beam skeleton 21 of the battery pack 2 is configured as the longitudinal beam of the floor 1, compared with the prior art, there is no need to design a separate longitudinal beam in the floor 1. Such a configuration facilitates the structural design of the floor 1 and helps to increase the available space of the floor 1, for example, it helps to increase the space for arranging the battery pack 2, so that the battery pack installation structure 100 can be equipped with a larger battery pack 2, which helps to improve the endurance of the battery pack installation structure 100.

[0048] In summary, according to the battery pack mounting structure 100 of the embodiment of the utility model, the longitudinal beam frame 21 of the battery pack 2 is configured as the longitudinal beam of the floor 1, so as to achieve the lightweight design and cost reduction effect of the battery pack mounting structure 100, and it is also beneficial to improve the endurance of the battery pack mounting structure 100.

[0049] In some embodiments of the present invention, Figure 1-Figure 6 As shown, the first cross beam 11 and the second cross beam 12 are both connected between the two threshold beams 14, there are two longitudinal beam frames 21, and the two longitudinal beam frames 21 are opposite and spaced apart in the width direction of the battery pack mounting structure 100. When the battery pack 2 is assembled on the floor 1, the longitudinal beam frames 21 and the threshold beam 14 on the same side of the battery pack mounting structure 100 are adjacent and spaced apart, and a support beam 15 is provided between the corresponding longitudinal beam frames 21 and the threshold beam 14, so that the support beam 15 can be supported between the corresponding longitudinal beam frames 21 and the threshold beam 14 in the width direction of the battery pack mounting structure 100. The force is transmitted between the frame 21 and the threshold beam 14. For example, during a lateral collision of the battery pack mounting structure 100, the force acting on the threshold beam 14 can be transmitted to the longitudinal beam frame 21 through the support beam 15. The force can be further transmitted to the first cross beam 11 and the second cross beam 12 through the longitudinal beam frame 21 and dispersed to the entire floor 1 to avoid stress concentration. In addition, since the support beam 15 is supported between the corresponding longitudinal beam frame 21 and the threshold beam 14, the risk of deformation of the threshold beam 14 can also be greatly reduced, thereby reducing the lateral intrusion of the battery pack mounting structure 100 and protecting the vehicle's drivers and passengers.

[0050] like Figure 1-Figure 6 As shown, in some embodiments, in the width direction of the battery pack mounting structure 100 (i.e., the Y direction shown in the figure), one of the two sill beams 14 is constructed as a left sill beam of the vehicle, and the other of the two sill beams 14 is constructed as a right sill beam of the vehicle, and in the width direction of the battery pack mounting structure 100, the first cross beam 11 and the second cross beam 12 are both connected between the left sill beam and the right sill beam to ensure the structural strength of the floor 1, so that when the battery pack 2 is detached from the floor 1, the floor 1 can still have a certain structural strength. In addition, the bottom plate member 13 is also fixedly connected to the sill beam 14 to further ensure the structural strength of the floor 1.

[0051] like Figure 2 , Figure 4 and Figure 6As shown, a plurality of support beams 15 are connected between the corresponding longitudinal beam frame 21 and the threshold beam 14. The plurality of support beams 15 are arranged in sequence along the length direction of the battery pack mounting structure 100, and two adjacent support beams 15 are spaced apart. By providing a plurality of support beams 15 between the corresponding longitudinal beam frame 21 and the threshold beam 14, the force between the corresponding longitudinal beam frame 21 and the threshold beam 14 can be effectively transmitted.

[0052] like Figure 1-Figure 8 As shown, in some embodiments, the battery pack 2 has a longitudinal beam frame 21 on both sides. When the battery pack 2 is assembled on the floor 1, the longitudinal beam frame 21 located on the left side of the battery pack mounting structure 100 corresponds to the left sill beam, and the longitudinal beam frame 21 located on the right side of the battery pack mounting structure 100 corresponds to the right sill beam, and the corresponding longitudinal beam frames 21 and the sill beam 14 are spaced apart in the width direction of the battery pack mounting structure 100. The corresponding longitudinal beam frames 21 and the sill beam 14 are provided with support beams 15, so that the support beams 15 are supported between the corresponding longitudinal beam frames 21 and the sill beam 14 in the width direction of the battery pack mounting structure 100. It should be supplemented that the width direction of the battery pack mounting structure 100 is the Y direction shown in the figure.

[0053] like Figure 4 and Figure 6 As shown, in some embodiments, a support beam 15 is provided between the corresponding longitudinal beam frame 21 and the threshold beam 14, and the support beam 15 is extended along the width direction of the battery pack mounting structure 100, and one end of the support beam 15 is fixedly connected to the corresponding threshold beam 14 to fix the position of the support beam 15 on the floor 1. When the battery pack 2 is assembled on the floor 1, the corresponding support beam 15 fixedly connected to the corresponding threshold beam 14 is located between the corresponding longitudinal beam frame 21 and the threshold beam 14.

[0054] Combination Figure 5 and Figure 6 As shown, in the height direction of the battery pack mounting structure 100, the support beam 15 is located below the bottom plate member 13, wherein in some embodiments, along the extension direction of the support beam 15, one end of the support beam 15 is fixedly connected to the corresponding door sill beam 14, and the side of the support beam 15 facing the bottom plate member 13 is suitable for being fixedly connected to the bottom plate member 13, so that the support beam 15 is fixedly connected to both the door sill beam 14 and the bottom plate member 13, thereby improving the stability of the support beam 15 and reducing the risk of the support beam 15 being detached, and because the support beam 15 is connected to both the door sill beam 14 and the bottom plate member 13, the force acting on the support beam 15 can also be dispersed and transmitted through the door sill beam 14 and the bottom plate member 13, respectively, thereby reducing the risk of stress concentration.

[0055] In other embodiments, in the height direction of the battery pack mounting structure 100, the support beam 15 is fixed below the bottom plate member 13 so that the support beam 15 is located between the corresponding longitudinal beam frame 21 and the threshold beam 14, and in the width direction of the battery pack mounting structure 100, the support beam 15 is spaced apart from the corresponding longitudinal beam frame 21, and the support beam 15 is also spaced apart from the corresponding threshold beam 14, so that in the extension direction of the support beam 15, the two ends of the support beam 15 are respectively spaced apart from the corresponding longitudinal beam frame 21 and the threshold beam 14 to form a collapse space, which is beneficial to inducing the deformation of the bottom plate member 13 and absorbing part of the force acting on the floor 1, so that in the process of lateral collision of the battery pack mounting structure 100, the floor 1 can form a multi-stage deformation effect, which is beneficial to protecting the battery pack mounting structure 100 including the driver and passengers of the battery pack mounting structure 100.

[0056] In some embodiments of the present invention, Fig.10 As shown, the battery pack 2 also has at least one cross beam frame 22, and the cross beam frame 22 is connected between the two longitudinal beam frames 21, which can not only ensure the structural strength of the battery pack 2, but also help to improve the structural strength of the battery pack installation structure 100.

[0057] Combination Fig.10 and Figure 4 As shown, in some embodiments, when the battery pack 2 is assembled on the floor 1, the crossbeam frame 22 is extended along the width direction of the battery pack mounting structure 100, and the two ends of the crossbeam frame 22 are respectively fixedly connected to the two oppositely arranged longitudinal beam frames 21. Since the support beam 15 is arranged between the corresponding longitudinal beam frame 21 and the door sill beam 14, and the crossbeam frame 22 is connected between the opposite longitudinal beam frames 21, when the battery pack mounting structure 100 has a side collision, the force acting on the door sill beam 14 on one side of the battery pack mounting structure 100 can be transmitted along the support beam 15 to the longitudinal beam frame 21 on the corresponding side in sequence, and then transmitted to the longitudinal beam frame 21 on the other side through the crossbeam frame 22, and then can also be transmitted to the support beam 15 on the other side through the longitudinal beam frame 21 on the other side, and then the force can be transmitted to the door sill beam 14 on the other side. Therefore, by providing the crossbeam frame 22, it is beneficial to disperse the force acting on the floor 1, reduce the risk of stress concentration in the floor 1, and improve the safety of the battery pack mounting structure 100.

[0058] In addition, since the two ends of the longitudinal beam frame 21 are respectively connected to the first cross beam 11 and the second cross beam 12, and the cross beam frame 22 is connected between the opposite longitudinal beam frames 21, when the battery pack 2 is assembled on the floor 1, such a design is beneficial to improve the structural strength of the battery pack installation structure 100 through the structural relationship between the battery pack 2 and the floor 1, for example, the torsional stiffness of the battery pack installation structure 100 can be improved.

[0059] Therefore, the battery pack 2 has a cross beam frame 22 connected between two relatively arranged longitudinal beam frames 21, which can not only ensure the structural strength of the battery pack 2, but also help to improve the safety performance of the battery pack installation structure 100 when the battery pack 2 is assembled on the floor 1.

[0060] In some embodiments of the present invention, Fig.10 As shown, the battery pack 2 also has two end beams 23, which are connected between the two longitudinal beam frames 21. In the length direction of the battery pack mounting structure 100, the two end beams 23 are opposite and spaced apart, and the beam frame 22 is located between the two end beams 23.

[0061] like Fig.10 As shown, in some embodiments, the two end cross beams 23 are connected between the two longitudinal beam frames 21 to jointly define a accommodating space 24, and the battery pack 2 may also have an upper cover plate 25 and a lower cover plate 26. Along the thickness direction of the battery pack 2, the upper cover plate 25 and the lower cover plate 26 are relatively arranged and are respectively located on both sides of the end cross beam 23 and the longitudinal beam frame 21. The upper cover plate 25 and the lower cover plate 26 respectively cover the two side openings of the accommodating space 24 to define an accommodating cavity, and the accommodating cavity is used to arrange battery cells, and the battery cells are used to store and release electrical energy. By arranging the battery cells in the accommodating cavity, the end cross beams 23, the longitudinal beam frame 21, the upper cover plate 25 and the lower cover plate 26 can all protect the battery cells located in the accommodating cavity, reduce the risk of battery cell failure, such as the battery cells being hit and burning, exploding, etc., thereby improving the safety of the battery pack 2.

[0062] like Fig.10 As shown, in some embodiments, the crossbeam frame 22 is located in the receiving cavity to divide the receiving cavity into a plurality of sub-receiving cavities, and two adjacent sub-receiving cavities can be in an independent state, and at least one battery cell is arranged in each sub-receiving cavity. The crossbeam frame 22 is connected between the two longitudinal beam frames 21 and is located between the two end crossbeams 23, so that the crossbeam frame 22 is located in the receiving cavity, which can not only improve the structural strength of the battery pack 2, but also improve the structural strength of the battery pack installation structure 100 when the battery pack 2 is assembled on the floor 1, and improve the safety of the battery pack installation structure 100. In addition, the crossbeam frame 22 is located in the receiving cavity to divide the receiving cavity into a plurality of independent sub-receiving cavities, so that when a battery cell in any of the plurality of sub-receiving cavities has a fault such as combustion or explosion, it can avoid affecting the battery cells in other sub-receiving cavities, reduce the overall danger of the battery pack 2, and help protect the driver and passengers of the battery pack installation structure 100.

[0063] In some embodiments of the present invention, Fig.10As shown, the battery pack 2 also has a middle longitudinal beam 27, which extends along the length direction of the battery pack mounting structure 100. The middle longitudinal beam 27 and the cross beam frame 22 are cross-arranged, and the middle longitudinal beam 27 is connected between the two end cross beams 23. The provision of the middle longitudinal beam 27 is beneficial to improving the structural strength of the battery pack 2.

[0064] like Fig.10 As shown, in some embodiments, the middle longitudinal beam 27 is arranged in parallel with the longitudinal beam frame 21, the middle longitudinal beam 27 is arranged crosswise with the two cross beam frames 22, and the middle longitudinal beam 27 is located between the two end cross beams 23, and the two ends of the middle longitudinal beam 27 are respectively fixedly connected to the two end cross beams 23, so that the longitudinal beam frame 21, the cross beam frame 22, the middle longitudinal beam 27 and the end cross beams 23 have a fixed connection relationship. It can also be understood that a direct fixed connection and an indirect fixed connection relationship are formed between the above-mentioned four structural members, thereby further improving the structural strength of the battery pack 2, and when the battery pack 2 is assembled on the floor 1, the structural strength of the battery pack mounting structure 100 can be further improved.

[0065] In some embodiments of the present invention, Fig.10 and Figure 4 As shown, when the battery pack 2 is assembled on the floor 1, the crossbeam frame 22 and the support beam 15 are arranged correspondingly in the width direction of the battery pack mounting structure 100. It can also be understood that in the width direction of the battery pack mounting structure 100, the crossbeam frame 22 and the support beam 15 are located on the same axis, so that when the battery pack mounting structure 100 has a lateral collision, since the crossbeam frame 22 and the support beam 15 are located on the same axis in the width direction of the battery pack mounting structure 100, it is beneficial to the conduction of the force. In addition, in this arrangement, in the width direction of the battery pack mounting structure 100, the support beam 15 is indirectly made between the sill beam 14 and the crossbeam frame 22, which can reduce the risk of excessive deformation of the sill beam 14, thereby reducing the lateral intrusion of the battery pack mounting structure 100 and protecting the driver and passengers of the vehicle.

[0066] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the floor 1 may also have a seat cross beam 16, which is fixedly connected between the two door sill beams 14. The seat cross beam 16 is fixedly connected between the two door sill beams 14, thereby further limiting the relative positions of the two door sill beams 14, so as to further improve the structural strength of the floor 1, and in the height direction of the battery pack mounting structure 100, the seat cross beam 16 is located on the upper side of the support beam 15, so that the seat cross beam 16 is located in the passenger compartment of the battery pack mounting structure 100, so that the seat cross beam 16 is used to install the seat of the battery pack mounting structure 100.

[0067] In some embodiments of the present invention, Figure 1-10 As shown, in the height direction of the battery pack mounting structure 100 , the orthographic projection of the seat cross beam 16 at least partially overlaps with the orthographic projection of the cross beam frame 22 , so as to further enhance the structural strength of the battery pack mounting structure 100 .

[0068] Combination Figure 1-10 As shown, in some embodiments, when the battery pack 2 is assembled on the floor 1, the seat cross beam 16 and the corresponding cross beam frame 22 are arranged relative to each other in the height direction of the battery pack mounting structure 100, that is, the seat cross beam 16 is located above the corresponding cross beam frame 22, and in some embodiments, in the width direction of the battery pack mounting structure 100, the cross beam frame 22 and the support beam 15 are located on the same axis, thereby, the corresponding seat cross beam 16, the support beam 15 and the cross beam frame 22 are combined on the battery pack mounting structure 100 to form a cross beam structure, thereby improving the structural strength of the battery pack mounting structure 100.

[0069] In some embodiments of the present invention, Fig.10 As shown, the crossbeam frame 22 has a first through hole 220, and the seat crossbeam 16 has a second through hole 160. In the height direction of the battery pack mounting structure 100, the first through hole 220 corresponds to the second through hole 160, so that the fixing piece used to fix the battery pack 2 to the seat crossbeam 16 is suitable for passing through the first through hole 220 and the second through hole 160, and the fixing piece is fixedly connected to the crossbeam frame 22 and the seat crossbeam 16, so that the battery pack 2 is fixedly assembled on the floor 1, and at the same time, the fixed connection effect of the crossbeam frame 22 and the seat crossbeam 16 is achieved, thereby improving the structural strength of the vehicle.
