[0043] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are well known to those skilled in the art. The following description of the embodiments is merely provided to give a better understanding of the present application by showing examples of the present application.

[0044] It should be noted that, in this document, the terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0045] The frame structure, as the main structure of the vehicle, carries the weight of the body, engine, chassis and all other components, and also provides a position for the installation and fixation of the engine, suspension system, steering system, etc. During the driving, turning, braking and other processes of the vehicle, the frame structure maintains the stability and rigidity of the vehicle body and ensures the handling performance of the vehicle.

[0046] Many structures in the vehicle are directly installed on the frame structure, but for smaller structures, the distance between the two ends cannot be adapted to the distance between the longitudinal beams in the frame structure, which is not convenient for installation.

[0047] In view of this, in a first aspect, please refer to Figure 1 and Figure 2The embodiment of the present application provides a vehicle frame structure 100, which comprises a first longitudinal beam 10, a second longitudinal beam 20, a first cross beam 30, a second cross beam 40 and a mounting longitudinal beam 50, the first longitudinal beam 10 and the second longitudinal beam 20 extend along a first direction X and are spaced apart along a second direction Y, the first cross beam 30 and the second cross beam 40 both extend along the second direction Y and are spaced apart along the first direction X. The two ends of the first cross beam 30 and the second cross beam 40 are connected to the first longitudinal beam 10 and the second longitudinal beam 20 to enclose a receiving cavity Q1 which is arranged through in a third direction Z, the first direction X, the second direction Y and the third direction Z intersect with each other. The two ends of the mounting longitudinal beam 50 in the first direction X are connected to the first cross beam 30 and the second cross beam 40 respectively, and the receiving cavity Q1 comprises a first space K1 and a second space K2 which are located on both sides of the mounting longitudinal beam 50 along the second direction Y. The bottom of the mounting longitudinal beam 50 along the third direction Z has a first surface, the top of the first longitudinal beam 10 along the third direction Z has a second surface, and at least part of the first surface is located above the second surface along the third direction Z to form a receiving channel D1 which communicates the first space K1 and the second space K2.

[0048] The vehicle frame structure 100 in the embodiment of the present application can be used as the main frame of the vehicle, provides a basic support frame for the vehicle, bears the weight of the vehicle body, engine and all other components, and provides a mounting and fixing position for the engine, suspension system and steering system. The vehicle frame structure 100 in the embodiment of the present application can be applied to a fuel automobile, a pure electric automobile or a range extended automobile.

[0049] Specifically, the vehicle frame structure 100 provided by the embodiment of the present application adopts a side beam structure, which comprises the first longitudinal beam 10 and the second longitudinal beam 20 which extend along the first direction X and are spaced apart along the second direction Y, wherein the first direction X is the length direction of the vehicle, and the second direction Y is the width direction of the vehicle. The first longitudinal beam 10 and the second longitudinal beam 20 are respectively located on both sides of the vehicle in the width direction, and both extend along the length direction of the vehicle. In actual application, the first longitudinal beam 10 and the second longitudinal beam 20 do not strictly extend along the length direction of the vehicle, and both comprise a certain degree of bending, and the overall structure extends along the length direction of the vehicle. For example, when located at the front part of the vehicle, the spacing between the first longitudinal beam 10 and the second longitudinal beam 20 is relatively small, when located at the middle part of the vehicle, the spacing between the first longitudinal beam 10 and the second longitudinal beam 20 is relatively large, and when located at the rear part of the vehicle, the spacing between the first longitudinal beam 10 and the second longitudinal beam 20 is relatively small.

[0050] The frame structure 100 further comprises a first cross beam 30 and a second cross beam 40, the first cross beam 30 and the second cross beam 40 extend along the second direction Y and are spaced apart along the first direction X, two ends of the first cross beam 30 along the second direction Y are connected with the first longitudinal beam 10 and the second longitudinal beam 20 respectively, and two ends of the second cross beam 40 along the second direction Y are connected with the first longitudinal beam 10 and the second longitudinal beam 20 respectively. The first longitudinal beam 10, the first cross beam 30, the second longitudinal beam 20 and the second cross beam 40 are connected with each other to ensure that the frame structure 100 has a certain overall rigidity so as to provide support to the remaining structure and installation position.

[0051] The first longitudinal beam 10, the first cross beam 30, the second longitudinal beam 20 and the second cross beam 40 enclose a receiving cavity Q1 which is provided through along the third direction Z, and the receiving cavity Q1 is configured to accommodate the to-be-installed structure. Exemplarily, the to-be-installed structure can be a battery pack in a pure electric vehicle, or an engine in a fuel vehicle, or a range extender 200 in a range extended vehicle. When the to-be-installed structure is located inside the receiving cavity Q1, it is necessary to adapt the spacing between the to-be-installed structure and the first longitudinal beam 10, the first cross beam 30, the second longitudinal beam 20 and the second cross beam 40 in order to stably and reliably connect the to-be-installed structure.

[0052] Only by accommodating the to-be-installed structure in the receiving cavity Q1, directly installing the to-be-installed structure on the first longitudinal beam 10 or the second longitudinal beam 20, for some to-be-installed structures, the size of the to-be-installed structure does not match the spacing between the first longitudinal beam 10 and the second longitudinal beam 20, which will cause certain inconvenience. Exemplarily, during the extension of the first longitudinal beam 10 and the second longitudinal beam 20 along the length direction of the vehicle, the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the front of the vehicle is small, the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the middle of the vehicle is large, the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the rear of the vehicle is small, and the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the rear of the vehicle is larger than the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the front of the vehicle. In a range extended vehicle, the range extender 200 is generally installed at the front of the vehicle, and the size of the range extender 200 matches the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the front of the vehicle, and when the range extender 200 is installed at the rear of the vehicle, the size of the range extender 200 does not match the spacing between the portions of the first longitudinal beam 10 and the second longitudinal beam 20 located at the rear of the vehicle, which is not convenient for the installation of the range extender 200.

[0053] In order to facilitate the connection of the required installation structure to the vehicle, the frame structure 100 of the present application further comprises an installation longitudinal beam 50 extending along the first direction X and spaced apart from the first longitudinal beam 10 and the second longitudinal beam 20 along the second direction Y, the installation longitudinal beam 50 is connected to the first cross beam 30 and the second cross beam 40 at both ends along the first direction X, and the installation longitudinal beam 50 divides the accommodation cavity Q1 along the second direction Y into a first space K1 and a second space K2. The first space K1 and the second space K2 can be used for installing the to-be-installed structure, and the installation longitudinal beam 50 is arranged between the first longitudinal beam 10 and the second longitudinal beam 20, which can provide a new installation position for the to-be-installed structure installed in the accommodation cavity Q1. When the size of the to-be-installed structure is smaller than the distance between the first longitudinal beam 10 and the second longitudinal beam 20, the to-be-installed structure can be installed in the first space K1 between the first longitudinal beam 10 and the installation longitudinal beam 50 or in the second space K2 between the second longitudinal beam 20 and the installation longitudinal beam 50 by arranging the installation longitudinal beam 50, thereby improving the installation position of the to-be-installed structure with a size smaller than the distance between the first longitudinal beam 10 and the second longitudinal beam 20.

[0054] Further, in actual installation, the distance between the first cross beam 30 and the second cross beam 40 relates to the vehicle width, which is usually a fixed value and cannot be changed. In order to reduce the influence of the installation longitudinal beam 50 on the size of the accommodation cavity Q1 between the first cross beam 30 and the second cross beam 40, part of the structure of the installation longitudinal beam 50 is arranged protruding relative to the first longitudinal beam 10. The bottom of the installation longitudinal beam 50 along the third direction Z has a first surface, and the top of the first longitudinal beam 10 along the third direction Z has a second surface, the third direction Z being the height direction of the vehicle, at least part of the first surface is above the second surface along the third direction Z to form an accommodation passage D1 connecting the first space K1 and the second space K2. That is, the installation longitudinal beam 50 protrudes from the first longitudinal beam 10 in the height direction of the vehicle, and at least part of the bottom surface of the installation longitudinal beam 50 is above the first longitudinal beam 10, and the first space K1 and the second space K2 are connected to each other in the height dimension of the first longitudinal beam 10.

[0055] When the to-be-installed structure is inside the first space K1, one end of the to-be-installed structure towards the mounting longitudinal beam 50 can be located at the bottom of the mounting longitudinal beam 50, and the mounting longitudinal beam 50 is located above part of the structure in the to-be-installed structure, and the mounting longitudinal beam 50 forms a certain degree of avoidance to the to-be-installed structure. By protruding the mounting longitudinal beam 50 in the height direction of the vehicle, the mounting longitudinal beam 50 and the to-be-installed structure can have an overlapping part in the second direction Y, so that the to-be-installed structure can reasonably use the space size occupied by the mounting longitudinal beam 50 along the second direction Y, and reduce the influence of the added mounting longitudinal beam 50 on the distance between the first longitudinal beam 10 and the second longitudinal beam 20. For the protruding height size of the mounting longitudinal beam 50 protruding from the first longitudinal beam 10, the actual to-be-installed structure shape is set.

[0056] In the embodiment of the present application, the frame structure 100 comprises a first longitudinal beam 10 and a second longitudinal beam 20 extending along a first direction X and spaced apart in a second direction Y, wherein the first direction X is the length direction of the vehicle, and the second direction Y is the width direction of the vehicle. The first longitudinal beam 10 and the second longitudinal beam 20 are respectively located on both sides of the vehicle in the width direction, and both the first longitudinal beam 10 and the second longitudinal beam 20 extend along the length direction of the vehicle. The first cross beam 30 and the second cross beam 40 extend along the second direction Y and are spaced apart in the first direction X, and the two ends of the first cross beam 30 along the second direction Y are respectively connected to the first longitudinal beam 10 and the second longitudinal beam 20, and the two ends of the second cross beam 40 along the second direction Y are respectively connected to the first longitudinal beam 10 and the second longitudinal beam 20. In order to facilitate the connection and installation of the to-be-installed structure, the frame structure 100 further comprises an installation longitudinal beam 50, which divides the accommodation cavity Q1 into a first space K1 and a second space K2 along the second direction Y. The first space K1 and the second space K2 can be used for installing the to-be-installed structure, and the installation longitudinal beam 50 is arranged between the first longitudinal beam 10 and the second longitudinal beam 20, which can provide a new installation position for the to-be-installed structure installed in the accommodation cavity Q1. When the size of the to-be-installed structure is smaller than the distance between the first longitudinal beam 10 and the second longitudinal beam 20, the to-be-installed structure can be installed in the first space K1 between the first longitudinal beam 10 and the installation longitudinal beam 50 or in the second space K2 between the second longitudinal beam 20 and the installation longitudinal beam 50 by arranging the installation longitudinal beam 50, thereby improving the appropriate installation position for the to-be-installed structure with a size smaller than the distance between the first longitudinal beam 10 and the second longitudinal beam 20. At the same time, the installation longitudinal beam 50 protrudes from the first longitudinal beam 10, which can make the first space K1 and the second space K2 communicate with each other in the height dimension of the first longitudinal beam 10. When the to-be-installed structure is inside the first space K1, the end of the to-be-installed structure facing the installation longitudinal beam 50 can be located at the bottom of the installation longitudinal beam 50, so that the installation longitudinal beam 50 and the to-be-installed structure overlap in the second direction Y, so that the to-be-installed structure can reasonably use the space dimension along the second direction Y occupied by the installation longitudinal beam 50, thereby reducing the influence of the added installation longitudinal beam 50 on the distance between the first longitudinal beam 10 and the second longitudinal beam 20.

[0057] In some embodiments, referring to Figure 1 and Figure 2 , the installation longitudinal beam 50 comprises a first connecting section 51, an installation section 52 and a second connecting section 53 connected in sequence along the first direction X, and the bottom surface of the installation section 52 in the third direction Z is located above the second surface in the third direction Z. The end of the first connecting section 51 away from the installation section 52 is connected to the outer side wall of the first cross beam 30, and the end of the second connecting section 53 away from the installation section 52 is connected to the outer side wall of the second cross beam 40. The frame structure 100 further comprises a suspension structure 60 connected to the installation section 52.

[0058] The mounting longitudinal beam 50 comprises a first connecting section 51, a mounting section 52 and a second connecting section 53 arranged in sequence along the first direction X, the mounting section 52 is located at the middle position of the mounting longitudinal beam 50 along the first direction X, and the bottom surface of the mounting section 52 along the third direction Z is located above the second surface along the third direction Z. The to-be-mounted structure is mounted on the mounting section 52 to form a spacing with both ends of the mounting longitudinal beam 50, and the to-be-mounted structure is connected to the middle position of the mounting longitudinal beam 50, so that a relatively stable acting force can be generated on the mounting longitudinal beam 50, and the mounting longitudinal beam 50 can also generate a relatively stable supporting force on the to-be-mounted structure, thereby ensuring the connection stability between the to-be-mounted structure and the mounting longitudinal beam 50.

[0059] Further, the frame structure 100 further comprises a suspension structure 60 connected to the mounting section 52, and the to-be-mounted structure is connected to the mounting longitudinal beam 50 through the suspension structure 60, so that the connection softness between the to-be-mounted structure and the mounting longitudinal beam 50 can be improved, the to-be-mounted structure is allowed to shake relative to the mounting longitudinal beam 50 to a certain extent through the suspension, and the relative impact between the to-be-mounted structure and the mounting longitudinal beam 50 is reduced, thereby protecting the to-be-mounted structure and the mounting longitudinal beam 50 to a certain extent.

[0060] In some embodiments, at least part of the bottom surface of the first connecting section 51 along the third direction Z is located above the second surface along the third direction Z, the accommodation channel D1 comprises a first channel located on one side of the mounting section 52 and a second channel located on one side of the first connecting section 51, and the first channel and the second channel are arranged in communication.

[0061] The first connecting section 51 is directly extended upward from the connecting end of the first cross beam 30 to form a protruding structure of the mounting longitudinal beam 50, and the first channel located below the first connecting section 51 and the second channel located below the mounting section 52 are connected to each other to form an accommodation channel D1 with a large space size, thereby facilitating the arrangement of the to-be-mounted structure.

[0062] Optionally, at least part of the bottom surface of the second connecting section 53 along the third direction Z is located above the second surface along the third direction Z, and the accommodation channel D1 further comprises a third channel located on one side of the second connecting section 53, and the third channel and the second channel are arranged in communication to further expand the space size of the accommodation channel D1, thereby facilitating the arrangement of the to-be-mounted structure.

[0063] In some embodiments, the size of the first connecting section 51 along the second direction Y is greater than the size of the mounting section 52 along the second direction Y, and the distance between the suspension structure 60 and the first cross beam 30 is less than the distance between the suspension structure 60 and the second cross beam 40. And / or, the size of the second connecting section 53 along the second direction Y is greater than the size of the mounting section 52 along the second direction Y.

[0064] In order to improve the connection strength between the mounting longitudinal beam 50 and the first cross beam 30, the first connecting section 51 is widened, which facilitates the connection between the mounting longitudinal beam 50 and the first cross beam 30, and the size of the first connecting section 51 is enlarged to improve the strength of the first connecting section 51 and ensure the stable installation of the structure to be installed. Similarly, in order to facilitate the connection between the mounting longitudinal beam 50 and the second cross beam 40, the second connecting section 53 can be widened.

[0065] The mounting position of the suspension structure 60 on the mounting section 52, that is, the connection position between the structure to be installed and the mounting longitudinal beam 50, can be close to the first cross beam 30, so as to keep a certain safety distance between the structure to be installed and the second cross beam 40 and reduce the probability of collision between the structure to be installed and the second cross beam 40. Alternatively, the suspension structure 60 can be close to the second cross beam 40, so as to keep a certain safety distance between the structure to be installed and the first cross beam 30 and reduce the probability of collision between the structure to be installed and the second cross beam 40.

[0066] In actual setting, the first cross beam 30 and the second cross beam 40 can be located at the rear position of the vehicle, and the first cross beam 30 is located in front of the second cross beam 40. The suspension structure 60 close to the first cross beam 30 can make the structure to be installed closer to the gravity center of the vehicle, and improve the stability of the vehicle in driving.

[0067] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the mounting longitudinal beam 50 includes a first wall 541 and a second wall 551 which are arranged at a relative interval in the second direction Y, and a cavity structure is formed between the first wall 541 and the second wall 551. The first wall 541 is provided with a mounting hole K3 which communicates with the cavity structure. The suspension structure 60 is arranged in the mounting hole K3, one end of the suspension structure 60 is located in the cavity structure and connected with the second wall 551, and the other end of the suspension structure 60 is located outside the cavity structure and connected with the first wall 541.

[0068] The suspension structure 60 connects the structure to be installed to the mounting longitudinal beam 50, and the connection strength between the suspension structure 60 and the mounting longitudinal beam 50 needs to be ensured. Therefore, the cavity structure is formed in the mounting longitudinal beam 50, and the suspension structure 60 is connected to the inside of the cavity structure, so as to improve the connection strength between the suspension structure 60 and the mounting longitudinal beam 50.

[0069] The mounting longitudinal beam 50 comprises a first wall 541 and a second wall 551 oppositely arranged in the second direction Y, a cavity structure is formed between the first wall 541 and the second wall 551, and a mounting hole K3 in communication with the cavity structure is arranged on the first wall 541. The suspension structure 60 penetrates the mounting hole K3, so that part of the suspension structure 60 is inside the cavity structure, so as to increase the overlapping size between the suspension structure 60 and the mounting longitudinal beam 50, thereby improving the connection strength between the suspension structure 60 and the mounting longitudinal beam 50.

[0070] Further, one end of the suspension structure 60 inside the cavity structure is connected with the second wall 551, and the other end of the suspension structure 60 outside the cavity structure is connected with the first wall 541. Through the above arrangement, on the one hand, a plurality of connection points can be formed between the suspension structure 60 and the mounting longitudinal beam 50, thereby improving the connection strength between the suspension structure 60 and the mounting longitudinal beam 50; on the other hand, the first wall 541 and the second wall 551 of the mounting longitudinal beam 50 can be connected by the suspension structure 60, thereby improving the structural strength of the mounting longitudinal beam 50 itself.

[0071] In some embodiments, referring to Figures 1 to 5 , the second wall 551 comprises a first region 5511 oppositely arranged with the mounting hole K3 in the second direction Y and a second region 5512 located around the first region 5511, and at least part of the surface of the first region 5511 facing the first wall 541 is located on the side of the second region 5512 away from the first wall 541.

[0072] When the suspension structure 60 is connected inside the mounting hole K3, based on the structural characteristics of the suspension structure 60, the suspension structure 60 needs a certain swing space to relieve the relative impact between the to-be-mounted structure and the mounting longitudinal beam 50. Therefore, the first region 5511 oppositely arranged with the mounting hole K3 is arranged to be bent relative to the second region 5512 around it, at least part of the surface of the first region 5511 facing the first wall 541 is located on the side of the second region 5512 away from the first wall 541, so as to expand the distance between the first region 5511 and the first wall 541, thereby expanding the space around the suspension structure 60 and avoiding the swing of the suspension structure 60 to a certain extent.

[0073] In some embodiments, referring to Figures 1 to 6 , the suspension structure 60 comprises a suspension body 61 outside the cavity structure and a connecting piece 62 connecting the suspension body 61 and the mounting longitudinal beam 50, the connecting piece 62 comprises a first connecting part 621 connected to the suspension body 61 and penetrating the mounting hole K3, a second connecting part 622 arranged in the first direction X and connected to the mounting longitudinal beam 50, and a flexible connecting part 623 connected between the first connecting part 621 and the second connecting part 622.

[0074] The suspension body 61 is connected with the structure to be installed, the first connecting part 621 is connected with the suspension body 61, the second connecting part 622 is connected with the longitudinal beam 50, and the flexible connecting part 623 is connected between the first connecting part 621 and the second connecting part 622 to allow the suspension structure 60 to shake by itself, thereby allowing the structure to be installed to shake with the longitudinal beam 50. The projection of the first area 5511 in the second direction Y covers the projections of the suspension body 61 and the first connecting part 621 in the second direction Y, and partially overlaps with the projection of the flexible connecting part 623 in the second direction Y.

[0075] In some embodiments, the second connecting part 622 includes a first bending part 6221, a second bending part 6222 and a third bending part 6223 connected by bending, the first bending part 6221 and the third bending part 6223 are connected to the two ends of the second bending part 6222 along the second direction Y, and the first bending part 6221 and the third bending part 6223 are bent to the same side of the second bending part 6222. The first bending part 6221 is connected to the side of the second wall 551 facing the first wall 541, and the third bending part 6223 is connected to the side of the first wall 541 away from the second wall 551.

[0076] In order to improve the connection strength of the second connecting part 622 and the suspension structure 60, a certain bending structure is formed on the second connecting part 622, so that the second connecting part 622 can form a relatively fitted part with the first wall 541 and the second wall 551, so as to connect the second connecting part 622 with the suspension structure 60.

[0077] The first bending part 6221 is located inside the cavity structure, the first bending part 6221 is connected to the side of the second wall 551 facing the first wall 541, and the first bending part 6221 and the second wall 551 have overlapping positions in the second direction Y, so as to connect the first bending part 6221 and the second wall 551. The third bending part 6223 is located outside the cavity structure, the third bending part 6223 is connected to the side of the first wall 541 away from the second wall 551, and the third bending part 6223 and the first wall 541 have overlapping positions in the second direction Y, so as to connect the third bending part 6223 and the first wall 541.

[0078] The second bending part 6222 is connected between the first bending part 6221 and the third bending part 6223 and passes through the mounting hole K3, and the second bending part 6222 is indirectly connected between the first wall 541 and the second wall 551, so as to form a connecting piece 62 between the first wall 541 and the second wall 551 inside the cavity structure, thereby improving the structural strength of the longitudinal beam 50.

[0079] In some embodiments, the mounting longitudinal beam 50 comprises a first portion 54 and a second portion 55 arranged separately along the second direction Y, the first portion 54 comprises a first wall 541 and a first side 542 and a second side 543 connected to the first wall 541 on both sides in the third direction Z, and the second portion 55 comprises a second wall 551 and a third side 552 and a fourth side 553 connected to the second wall 551 on both sides in the third direction Z.

The surface of the first side 542 facing the second side 543 is connected to the third side 552, and the surface of the second side 543 facing the first side 542 is connected to the fourth side 553.

[0080] In order to facilitate the production of the mounting longitudinal beam 50, the mounting longitudinal beam 50 is arranged in a split structure, so as to facilitate the separate production of each split structure of the mounting longitudinal beam 50 and the assembly of the mounting longitudinal beam 50.

[0081] The mounting longitudinal beam 50 comprises a first portion 54 and a second portion 55 arranged separately along the second direction Y, and the first portion 54 and the second portion 55 can be connected or separated along the second direction Y. The two ends of the first portion 54 are connected to the first cross beam 30 and the second cross beam 40 respectively, and the first portion 54 ensures the integrity of the structure between the first cross beam 30 and the second cross beam 40, so that the first portion 54 can form a good support structure. Similarly, the two ends of the second portion 55 are connected to the first cross beam 30 and the second cross beam 40 respectively, and the second portion 55 can also ensure the integrity of the structure between the first cross beam 30 and the second cross beam 40, so as to facilitate the second portion 55 to form a good support structure.

The first side 542 and the third side 552 are partially in contact and connected to form a complete side wall, and the second side 543 and the fourth side 553 are partially in contact and connected to form a complete side wall. The first wall 541 and the second wall 551 are arranged opposite to each other in the second direction Y, and a cavity structure is formed between the first wall 541 and the second wall 551.

[0083] In some embodiments, the mounting longitudinal beam 50 further comprises a reinforcing member 56, and the reinforcing member 56 comprises a first reinforcing portion 561 located inside the cavity structure and connected to the first wall 541, and the first reinforcing portion 561 is arranged around the mounting hole K3.

[0084] When the mounting hole K3 is arranged on the first wall 541, the suspension structure 60 is arranged through the mounting hole K3, and the mounting hole K3 is adjacent to the first wall 541, which affects the overall strength of the first wall 541. In order to improve the overall strength of the first wall 541, the first reinforcing portion 561 is arranged on the side of the mounting hole K3, and the first reinforcing portion 561 is arranged to overlap the first wall 541 on the side of the mounting hole K3, thereby increasing the thickness of the structure on the side of the mounting hole K3, and improving the strength of the first wall 541 to a certain extent, and improving the structural stability of the first wall 541 on the side of the mounting hole K3.

[0085] In some embodiments, the reinforcing member 56 includes a second reinforcing portion 562 and a third reinforcing portion 563 connected to the first reinforcing portion 561 at both ends in the first direction X, the second reinforcing portion 562 is located on the side of the first reinforcing portion 561 facing the second wall 551, and the end of the second reinforcing portion 562 away from the first reinforcing portion 561 is connected to the second wall 551, and the third reinforcing portion 563 is located on the side of the first connecting portion 621 facing the second wall 551, and the end of the third reinforcing portion 563 away from the first reinforcing portion 561 is connected to the second wall 551. The suspension structure 60 is located between the second reinforcing portion 562 and the third reinforcing portion 563 in the first direction X.

[0086] Considering that the first wall 541 and the second wall 551 are arranged at intervals, and a cavity structure is formed between the first wall 541 and the second wall 551, in order to improve the connection strength between the first wall 541 and the second wall 551, thereby improving the connection strength of the suspension structure 60 relative to the mounting stringer 50, the reinforcing member 56 includes a second reinforcing portion 562 and a third reinforcing portion 563 connected to the first reinforcing portion 561 at both ends in the first direction X, the second reinforcing portion 562 is located on the side of the first reinforcing portion 561 facing the second wall 551, and the third reinforcing portion 563 is located on the side of the first reinforcing portion 561 facing the second wall 551, and the end of the second reinforcing portion 562 away from the first reinforcing portion 561 is connected to the second wall 551, and the end of the third reinforcing portion 563 away from the first reinforcing portion 561 is connected to the second wall 551.

[0087] The first reinforcing portion 561 is connected to the first wall 541, the second reinforcing portion 562 is connected between the first reinforcing portion 561 and the second wall 551, and the third reinforcing portion 563 is connected between the first reinforcing portion 561 and the second wall 551, and the reinforcing member 56 forms a support frame structure between the first wall 541 and the second wall 551, and can connect the first wall 541 and the second wall 551 to each other. At the same time, based on the arrangement of the second reinforcing portion 562 and the third reinforcing portion 563, the probability of the first wall 541 shaking alone can be reduced, and the overall stability of the mounting stringer 50 can be improved.

[0088] Further, the suspension structure 60 is located between the second reinforcing portion 562 and the third reinforcing portion 563, and a projection of the suspension structure 60 in the second direction Y is located inside a projection of the reinforcing member 56 in the second direction Y. The suspension structure 60 can be connected to the mounting longitudinal beam 50 stably by the reinforcing effect of the reinforcing member 56 on the first wall 541 and the second wall 551.

[0089] In some embodiments, in order to facilitate the connection between the second reinforcing portion 562 and the second wall 551, an end of the second reinforcing portion 562 away from the first reinforcing portion 561 is provided with a first flange 5621, and the first flange 5621 is attached to the second wall 551 in the second direction Y to facilitate the connection between the second reinforcing portion 562 and the second wall 551. Similarly, an end of the third reinforcing portion 563 away from the first reinforcing portion 561 is provided with a second flange 5631, and the second flange 5631 is attached to the second wall 551 in the second direction Y to facilitate the connection between the third reinforcing portion 563 and the second wall 551.

[0090] Alternatively, the second reinforcing portion 562 and the second wall 551 are connected by welding, and the second wall 551 is provided with a welding hole 5513 penetrating through, and a projection of the welding hole 5513 in the second direction Y is located inside a projection of the first flange 5621 in the second direction Y. A technician can weld the second reinforcing portion 562 and the second wall 551 through the welding hole 5513 from a side of the second wall 551 away from the first wall 541. The third reinforcing portion 563 and the second wall 551 can also be connected by welding, and the principle and mode of connection are similar to those between the second reinforcing portion 562 and the second wall 551, which will not be described here.

[0091] The mounting longitudinal beam 50 provided by the embodiments of the present application adopts a split structure and is provided with the reinforcing member 56, which can be assembled and welded in the following manner. First, the reinforcing member 56 is welded and connected to the first part 54, and the first reinforcing portion 561 in the reinforcing member 56 is arranged on the periphery of the mounting hole K3 in the first wall 541. Second, the second part 55 and the first part 54 are welded and connected from the outside, so that the second reinforcing portion 562 and the third reinforcing portion 563 in the reinforcing member 56 are in contact with the second wall 551, and the second reinforcing portion 562 and the third reinforcing portion 563 are welded to the second part 55 through the welding hole 5513, thereby realizing the connection between the reinforcing member 56, the first part 54, and the second part 55.

[0092] The suspension structure 60 can be connected to the mounting longitudinal beam 50 by means of bolts and nuts. First, nuts to be connected are pre-welded to one side of the first reinforcing portion 561 facing the second wall 551 and one side of the first bent portion 6221 facing the third bent portion 6223, then the suspension structure 60 is inserted into the mounting hole K3, so that the first bent portion 6221 is in contact with the second wall 551, and the third bent portion 6223 is in contact with the first wall 541. Corresponding connecting holes are arranged on the second wall 551 and the first bent portion 6221, and the bolts are inserted into the connecting holes and connected with the nuts pre-welded to the first bent portion 6221 to connect the second wall 551 and the first bent portion 6221. At the same time, corresponding connecting holes are arranged on the reinforcing member 56, the first wall 541 and the third bent portion 6223, and the bolts are inserted into the connecting holes and connected with the nuts pre-welded to the reinforcing member 56 to connect the first wall 541 and the third bent portion 6223.

[0093] Optionally, considering that the formation of the mounting hole K3 on the first portion 54 reduces the structural strength of the first portion 54, in order to ensure the connection strength of the suspension structure 60 and the first portion 54, the number of connecting holes and bolts and nuts arranged on one side of the first portion 54 of the mounting longitudinal beam 50 can be more than the number of connecting holes and bolts and nuts arranged on one side of the second portion 55 of the mounting longitudinal beam 50. For example, four groups of connecting holes, bolts and nuts can be arranged on one side of the first portion 54 of the mounting longitudinal beam 50, and two groups of connecting holes, bolts and nuts can be arranged on one side of the second portion 55 of the mounting longitudinal beam 50.

[0095] Further, the vehicle further includes an oil tank, and the oil tank is located in the second space K2. Since part of the range extender 200 is located below the mounting longitudinal beam 50, the distance between the oil tank and the range extender 200 can be smaller than the size of the mounting longitudinal beam 50 along the second direction Y, so as to fully utilize the distance between the first longitudinal beam 10 and the second longitudinal beam 20, and reasonably arrange the oil tank and the range extender 200.

[0096] Although the utility model has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the utility model and equivalent replacements can be made to the components therein. In particular, the technical features mentioned in each embodiment can be combined in any manner as long as there is no structural conflict.
