The embodiments described below by reference to the accompanying drawings are exemplary and are intended only for the purpose of explaining the present application, and should not be construed as limiting the present application.

[0038] A vehicle body framework assembly 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0039] Referring to Figure 1 and Figure 2 , the vehicle body framework assembly 100 according to the first embodiment of the present application includes a framework main body 10 and a wheel house framework assembly 50, the framework main body 10 including two vehicle body longitudinal beams 101 extending in the front-rear direction and spaced apart in the left-right direction, the vehicle body longitudinal beams 101 having a plurality of sub-frame mounting points for connecting a sub-frame of a vehicle.

[0040] It should be explained that in the description of the present application, "a plurality of" means two or more.

[0041] The wheel cover framework assembly 50 is two, and the two wheel cover framework assemblies 50 are connected to the left and right ends of the framework main body 10 respectively, each wheel cover framework assembly 50 comprises a wheel cover upper edge beam 51 and a plurality of wheel cover support beams, the wheel cover upper edge beam 51 is located above the vehicle body longitudinal beam 101, and the wheel cover upper edge beam 51 is spaced apart from the vehicle body longitudinal beam 101 in the left-right direction;

[0042] The wheel cover support beam connects between the wheel cover upper edge beam 51 and the vehicle body longitudinal beam 101, and the plurality of wheel cover support beams are arranged in the front-rear direction; the connecting point of the wheel cover support beam and the corresponding vehicle body longitudinal beam 101 is a wheel cover connecting point, and at least one of the plurality of sub-frame mounting points is opposite to one wheel cover connecting point in the up-down direction.

[0043] At least one of the sub-frame mounting points is arranged to be opposite to one wheel cover connecting point in the up-down direction, and the structural strength of the vehicle body longitudinal beam 101 at this sub-frame mounting point is higher, so that when the sub-frame exerts force on the vehicle body longitudinal beam 101, the degree of deformation of the vehicle body longitudinal beam 101 under stress can be reduced, the relative displacement between the plurality of sub-frame mounting points can be reduced, the sub-frame can be reliably connected to the vehicle body framework, the sub-frame can reliably work, the sub-frame can reliably support the vehicle body framework assembly 100, and the overall performance of the vehicle is improved.

[0044] By arranging the connecting point of the wheel cover support beam and the corresponding vehicle body longitudinal beam 101 to be opposite to the sub-frame mounting point, the structural strength of the vehicle body longitudinal beam 101 at the sub-frame mounting point is improved, so that additional reinforcing components do not need to be added to improve the structural strength of the vehicle body longitudinal beam 101, the components of the vehicle body framework assembly 100 can be arranged less, the overall structure of the vehicle body framework is simple, the production cost of the vehicle body framework assembly 100 can be reduced, and the overall performance of the vehicle is improved.

[0045] According to the vehicle body framework assembly 100 of the present application, by arranging at least one of the plurality of sub-frame mounting points to be opposite to the wheel cover connecting point in the up-down direction, the structural strength at the sub-frame mounting point can be improved, the relative displacement between the plurality of sub-frame mounting points can be effectively reduced, the sub-frame can be reliably connected to the vehicle body framework assembly 100, the sub-frame can reliably work, the sub-frame can reliably support the vehicle body framework assembly 100, and the overall performance of the vehicle is improved.

[0046] Reference Figure 1 and Figure 2According to some embodiments of the present application, the vehicle body longitudinal beam 101 is provided with a reinforcing structure, and each sub-frame mounting point except the sub-frame mounting point opposite to the wheel cover connecting point in the up-down direction corresponds to a reinforcing structure. By arranging the reinforcing structure corresponding to the sub-frame mounting point, the structural strength of the vehicle body longitudinal beam 101 at the sub-frame mounting point can be improved, so that the structural strength of the vehicle body longitudinal beam 101 at each sub-frame mounting point is higher, thereby more effectively allowing the relative displacement between the multiple sub-frame mounting points, so that the sub-frame can be reliably connected to the vehicle body framework assembly 100, so that the sub-frame can reliably work, and the overall performance of the vehicle is improved.

[0047] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, the framework body 10 includes a shelf support beam 31, a shelf cross beam 32, and a roof longitudinal beam 41, the roof longitudinal beam 41 is two, and the two roof longitudinal beams 41 are arranged in the left-right direction, the roof longitudinal beam 41 is above the wheel cover upper beam 51, and the roof longitudinal beam 41 extends in the front-rear direction, the roof longitudinal beam 41 is used to support the roof of the vehicle, and each roof longitudinal beam 41 is connected with a shelf support beam 31 corresponding to the wheel cover upper beam 51, and the shelf cross beam 32 is connected between the two shelf support beams 31.

[0048] When the vehicle body longitudinal beam 101 is subjected to a force, the force can be transmitted from the sub-frame mounting point to the wheel cover support beam, and then transmitted from the wheel cover support beam to the shelf support beam 31, the shelf support beam 31 can transmit a part of the force to the roof longitudinal beam 41, and the shelf support beam 31 can transmit a part of the force to the shelf support beam 31 on the other side through the shelf cross beam 32, and the force transmitted by the shelf support beam 31 on the other side is transmitted to the roof longitudinal beam 41 on the other side and the wheel cover upper beam 51 on the other side.

[0049] In this way, the force received by the vehicle body longitudinal beam 101 can be reliably and smoothly transmitted to various parts of the vehicle body framework assembly 100, effectively preventing the force from being too concentrated at a certain point of the vehicle body framework assembly 100 to cause the vehicle body framework assembly 100 to deform greatly, effectively dissipating the force transmitted to the vehicle body framework assembly 100, improving the torsional stiffness of the vehicle, and improving the overall performance of the vehicle.

[0050] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, the vehicle body longitudinal beam 101 is provided with a reinforcing beam 56, one end of the reinforcing beam 56 is connected with the shelf cross beam 32, the other end of the reinforcing beam 56 is connected with the vehicle body longitudinal beam 101, the connecting point of the other end of the reinforcing beam 56 with the vehicle body longitudinal beam 101 is a reinforcing connecting point, and the reinforcing connecting point is opposite to one of the sub-frame mounting points in the up-down direction.

[0051] When the vehicle body longitudinal beam 101 is subjected to force, the force can be transmitted from the reinforcing connecting point to the reinforcing beam 56, then transmitted from the reinforcing beam 56 to the parcel shelf transverse beam 32, then transmitted from the parcel shelf transverse beam 32 to the parcel shelf support beam 31, then transmitted from the parcel shelf transverse beam 32 to the wheelhouse upper side beam 51, and then transmitted from the wheelhouse support beam back to the vehicle body longitudinal beam 101, so that the vehicle body longitudinal beam 101, the reinforcing beam 56, the parcel shelf transverse beam 32, the parcel shelf support beam 31, the wheelhouse upper side beam 51 and the wheelhouse support beam form a force transmission cycle, effectively dissipating the force transmitted to the vehicle body frame assembly 100, improving the torsional stiffness of the vehicle, and improving the overall performance of the vehicle.

[0052] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, the rear end of the roof longitudinal beam 41 is connected to the wheelhouse upper side beam 51, the parcel shelf support beam 31 extends in the up-down direction, and the parcel shelf support beam 31 is connected between the wheelhouse upper side beam 51 and the roof longitudinal beam 41, and the frame body 10 further comprises a connecting beam 43 extending in the front-rear direction, and the two ends of the connecting beam 43 in the front-rear direction are respectively connected to the parcel shelf support beam 31 and the roof longitudinal beam 41.

[0053] The parcel shelf support beam 31, the roof longitudinal beam 41 and the wheelhouse upper side beam 51 can define a generally triangular annular structure, which can make the overall structure of the vehicle body frame assembly 100 more reliable and stable, and make the vehicle body frame assembly 100 more stable; when the vehicle body longitudinal beam 101 is subjected to force, the generally triangular annular structure can effectively dissipate and absorb the force received by the vehicle body longitudinal beam 101, and improve the overall performance of the vehicle.

[0054] By connecting the parcel shelf support beam 31 and the roof longitudinal beam 41 through the connecting beam 43, the roof longitudinal beam can be more reliably fixed relative to the wheelhouse frame assembly, and the overall structure of the vehicle body frame assembly can be more stable; at the same time, this can make the connecting beam 43, the parcel shelf support beam 31, the roof longitudinal beam 41 and the wheelhouse upper side beam 51 define multiple force transmission cycles, which can more effectively dissipate and absorb the force received by the vehicle body longitudinal beam 101, and improve the overall performance of the vehicle

[0055] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, the wheelhouse frame assembly 50 further comprises a shock absorber mounting bracket 61 and a force transmission beam 62, the shock absorber mounting bracket 61 is connected between the wheelhouse upper side beam 51 and the vehicle body longitudinal beam 101, and the force transmission beam 62 is connected between the shock absorber mounting bracket 61 and the parcel shelf transverse beam 32.

[0056] When the damper exerts force on the damper mounting bracket 61, the force can be transmitted from the damper mounting bracket 61 to the force transmission beam 62, then transmitted by the force transmission beam 62 to the shelf cross beam 32, transmitted by the shelf cross beam 32 to the shelf support beam 31, then transmitted by the shelf cross beam 32 to the wheel cover upper edge beam 51, and transmitted back to the damper mounting bracket 61 by the wheel cover support beam.

[0057] In this way, the damper mounting bracket 61, the force transmission beam 62, the shelf cross beam 32, the shelf support beam 31, and the wheel cover upper edge beam 51 form a force transmission cycle, so that the force transmitted by the damper to the damper mounting bracket 61 can be effectively dissipated, and the damper can reliably work, thereby improving the overall performance of the vehicle.

[0058] Referring to Figure 1 and Figure 2 In some embodiments of the present application, the wheel cover support beam includes a front support beam 52, one end of the front support beam 52 is connected to the front portion of the wheel cover upper edge beam 51, the other end of the front support beam 52 is connected to the vehicle body longitudinal beam 101, and the other end of the front support beam 52 is opposite to the subframe mounting point in the up-down direction.

[0059] The structure strength of the intersection of the front support beam 52 and the vehicle body longitudinal beam 101 is high, and the intersection of the front support beam 52 and the vehicle body longitudinal beam 101 is arranged to be opposite to the subframe mounting point in the up-down direction, which can improve the reliability of the overall structure of the vehicle body framework assembly 100, so that the subframe can be reliably connected to the vehicle body framework assembly 100 and reliably support the vehicle body framework assembly 100.

[0060] Referring to Figure 1 and Figure 2 In some embodiments of the present application, the vehicle body longitudinal beam 101 includes a rear floor longitudinal beam 21, a rocker beam 11, and a connecting piece 12, the rocker beam 11 is connected to the front portion of the connecting piece 12, the rear floor longitudinal beam 21 is connected to the rear portion of the connecting piece 12, and the other end of the front support beam 52 is connected to the rocker beam 11, i.e., the subframe mounting point opposite to the other end of the front support beam 52 is located below the connecting piece 12. For example, the connecting piece 12 can be a cast piece.

[0061] For example, the framework main body 10 can include a front floor framework assembly 1 and a rear floor framework assembly 2, the front floor framework assembly 1 includes a rocker beam 11, a front floor cross beam, and a connecting piece 12, the rocker beam 11 extends in the front-rear direction, the rocker beam 11 is two and arranged in the left-right direction, the front floor cross beam is connected between the two rocker beams 11, the front floor cross beam is multiple, and the multiple front floor cross beams are arranged in the front-rear direction, and one connecting piece 12 is connected to the rear end of each rocker beam 11.

[0062] The rear floor framework assembly 2 comprises rear floor longitudinal beams 21 and rear floor cross beams 22. The rear floor longitudinal beams 21 extend in the front-rear direction, and there are two rear floor longitudinal beams 21 arranged in the left-right direction. The front ends of the rear floor longitudinal beams 21 are connected to the connecting member 12. The rear floor cross beams 22 are connected between the two rocker beams 11, and there are multiple rear floor cross beams 22 arranged in the front-rear direction.

[0063] By arranging the connecting member 12 for connecting the rear floor longitudinal beam 21 and the rocker beam 11, the structural strength at the connecting member 12 is high. The subframe mounting point is arranged below the connecting member 12, and the structural strength at the subframe mounting point is high. The subframe can be reliably connected to the connecting member 12, and the subframe can reliably support the body framework assembly 100.

[0064] The front support beam 52 is connected to the rocker beam 11. The subframe can transmit part of the force to the rocker beam 11 through the connecting member 12. The rocker beam 11 can transmit part of the transmitted force to the wheelhouse upper cross beam through the front support beam 52. The wheelhouse framework assembly 50 and the rear floor framework assembly 2 dissipate part of the force transmitted by the subframe. The rocker beam 11 can transmit part of the transmitted force to the front floor framework assembly 1. The front floor framework assembly 1 dissipates part of the force transmitted by the subframe. The force transmitted by the subframe is evenly distributed to the entire body framework assembly 100, and the overall performance of the body framework assembly 100 is improved.

The front side vertical sub-plate 1211 and the front side horizontal sub-plate 1212 together with the middle plate portion 122 define a first connecting space. This provides mounting space for the rocker beam 11, ensuring that the rocker beam 11 can be fixedly connected to the connecting member 12.

[0067] The top end of the front vertical sub-plate 1211 is configured as an arc structure in the front-rear direction, a plurality of first reinforcing ribs 1213 are arranged and spaced apart in the front-rear direction on the upper side of the first connecting space and connected with the front vertical sub-plate 1211 and the front horizontal sub-plate 1212, so as to improve the structural strength of the front plate part 121, make the connection between the connecting part 12 and the rocker beam 11 more firm, and improve the structural strength of the vehicle body framework assembly 100.

[0068] The first reinforcing rib 1213 is configured as a nearly right-angled trapezoidal structure, two right-angled sides are connected with the front horizontal sub-plate 1212 and the front vertical sub-plate 1211 respectively, and the inclined surface extends from the end of the front horizontal sub-plate 1212 in the left-right direction to the top end of the front vertical sub-plate 1211, so as to ensure that the connection strength between the first reinforcing rib 1213 and the front plate part 121 is greater, thereby ensuring the installation effect of the first reinforcing rib 1213, and at the same time, the inclined side can provide a guiding effect on the impact force, thereby facilitating the transmission of the impact force.

[0069] The first vertical reinforcing rib 1214 and the first arc-shaped reinforcing rib 1215 are both arranged in a plurality of and connected to the side of the front vertical sub-plate 1211 away from the front horizontal sub-plate 1212, the first vertical reinforcing rib 1214 extends from the top end to the bottom end of the front vertical sub-plate 1211, the first arc-shaped reinforcing rib 1215 extends obliquely downward from one end of the front vertical sub-plate 1211 close to the middle plate part 122 to the other end of the front vertical sub-plate 1211, and the first vertical reinforcing rib 1214 and the first arc-shaped reinforcing rib 1215 are arranged in cross and define a concave cavity structure, so as to further improve the structural strength and stress effect between the front plate part 121 and the middle plate part 122, and improve the impact resistance and force guiding capability of the connecting part 12.

[0070] The rear plate part 123 includes a rear vertical sub-plate 1231, a rear horizontal sub-plate 1232, a second reinforcing rib 1233, a second vertical reinforcing rib 1234 and a second arc-shaped reinforcing rib 1235, the rear vertical sub-plate 1231 and the rear horizontal sub-plate 1232 together define a second connecting space with the middle plate part 122, so as to provide a mounting space for the rear floor longitudinal beam 21 and ensure that the rear floor longitudinal beam 21 can be smoothly and fixedly connected with the connecting part 12.

[0072] The second reinforcing rib 1233 is configured as a right-angled triangle structure, two right-angled sides are connected with the rear horizontal sub-plate 1232 and the rear vertical sub-plate 1231 respectively, and the hypotenuse extends from the Z-direction bottom end of the rear vertical sub-plate 1231 to the end face of the rear horizontal sub-plate 1232. Through the above setting, the connection strength of the rear plate part 123 can be ensured to be higher, and the hypotenuse can guide the force, thereby facilitating the transmission of the impact force.
