[0050] The following describes embodiments of the present invention in detail. 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0051] Reference below Figures 1-9 A body component 100 of a vehicle according to an embodiment of the present invention is described. The body component 100 can be applied to a vehicle, but the present application is not limited thereto. The body component 100 can be applied to other equipment that requires the body component 100. The present application takes the application of the body component 100 to a vehicle, where the body component 100 is the rear section of the vehicle as an example for explanation.

[0052] like Figure 1 As shown, the vehicle body assembly 100 according to an embodiment of the present invention includes: an upper structural member 1, a lower structural member 2, a left structural member 3 and a right structural member 4, the left structural member 3 and the right structural member 4 are opposite and spaced apart, the left structural member 3 and the right structural member 4 are connected between the upper structural member 1 and the lower structural member 2, and at least one of the upper structural member 1, the lower structural member 2, the left structural member 3 and the right structural member 4 has a cavity structure 10, and the cross-sectional area of ​​the cavity structure 10 is the same in the length direction of the cavity structure 10.

[0053] Specifically, if Figure 1 As shown, along the height direction of the vehicle (i.e. Figure 1The upper structure 1 and the lower structure 2 are arranged opposite to each other along the width direction of the vehicle (ie the Z direction shown in FIG). Figure 1 ), the left structural member 3 and the right structural member 4 are arranged opposite each other and spaced apart. The upper structural member 1, the lower structural member 2, the left structural member 3, and the right structural member 4 are connected together to form a closed ring structure. At least one of the upper structural member 1, the lower structural member 2, the left structural member 3, and the right structural member 4 has a cavity structure 10 therein. This improves the force transmission effect among the upper structural member 1, the lower structural member 2, the left structural member 3, and the right structural member 4, thereby enhancing the force transmission performance of the body assembly 100 and preventing the risk of stress concentration in the body assembly 100. Furthermore, the cross-sectional area of ​​the cavity structure 10 of the upper structural member 1 is the same along the length direction of the cavity structure 10, and the cross-sectional area of ​​the cavity structure 10 of the lower structural member 2 is the same along the length direction of the cavity structure 10 of the lower structural member 2.

[0054] Since the cross-sectional areas of the cavity structure 10 of the upper structural member 1 are the same along the length direction of the cavity structure 10 of the upper structural member 1, and the cross-sectional areas of the cavity structure 10 of the lower structural member 2 are the same along the length direction of the cavity structure 10 of the lower structural member 2, this is beneficial to improving the structural strength and rigidity of the upper structural member 1 and the lower structural member 2, and improving the handling stability of the vehicle. In addition, in the process of the upper structural member 1 and the lower structural member 2 transmitting the force (for example, the road load exerted on the vehicle during driving), it is beneficial for the force to be uniformly transmitted along the length direction of the upper structural member 1 and the length direction of the lower structural member 2, so that the force is evenly dispersed and transmitted to the vehicle body, reducing the risk of stress concentration in the upper structural member 1 and the lower structural member 2, thereby helping to weaken the road load excitation, improve the vehicle NVH (Noise, Vibration, Harshness) performance, and thus enhance the comfort perception experience of the driver and passengers.

[0055] Furthermore, along the length direction of the cavity structure 10 of the left structural member 3, at least a partial area of ​​the cavity formed by the left structural member 3 is constructed as the cavity structure 10, and along the length direction of the cavity structure 10 of the right structural member 4, at least a partial area of ​​the cavity formed by the right structural member 4 is constructed as the cavity structure 10, which is beneficial to improving the structural strength of the left structural member 3 and the right structural member 4, improving the handling stability of the vehicle, and is beneficial to uniformly transmitting the force along the length direction of the left structural member 3 and the length direction of the right structural member 4, so that the force is uniformly dispersed and transmitted to the vehicle body, reducing the risk of stress concentration in the left structural member 3 and the right structural member 4, thereby helping to further weaken the road load excitation, further improve the vehicle NVH performance, and further enhance the comfort perception experience of the driver and passengers.

[0056] Therefore, according to the body assembly 100 of the embodiment of the present invention, the structural strength and rigidity of the body assembly 100 are improved, which is beneficial to improving the handling stability of the vehicle. In addition, the body assembly 100 has good force transmission performance, which prevents the risk of stress concentration in the body assembly 100, is beneficial to reducing road load excitation, improving the NVH performance of the vehicle, and thus enhancing the comfort perception experience of the driver and passengers.

[0057] Furthermore, please combine Figure 1 、 Figure 2 and Figure 3 For reference, the upper structure 1, the lower structure 2, the left structure 3 and the right structure 4 together define a storage channel 20, which is arranged along the length direction of the vehicle (ie Figure 3 , the storage passage 20 connects the passenger compartment 200 of the vehicle with the trunk 300 of the vehicle, thereby achieving a communication effect between the passenger compartment 200 and the trunk 300. This allows users to place items from the passenger compartment 200 to the trunk 300, improving the user experience. Furthermore, the communication between the passenger compartment 200 and the trunk 300 increases the storage space of the vehicle, allowing the vehicle to carry larger items.

[0058] Specifically, when the passenger compartment 200 is connected with the trunk 300, part of the space in the passenger compartment 200 and the trunk 300 can both store items, thereby increasing the storage space of the vehicle and making it easier for users to load larger items. Moreover, when the passenger compartment 200 is connected with the trunk 300, the storage space has a larger length dimension along the length direction of the vehicle, so that when users load items, it is easier for users to load items with larger length dimensions, thereby improving the user experience.

[0059] In some embodiments of the present invention, Figure 4 As shown, the cross-sectional shape of the cavity structure 10 in the upper structural member 1 is a diamond. Furthermore, by setting the cross-sectional shape of the cavity structure 10 in the upper structural member 1 to a diamond, it is ensured that the cross-sectional shape of the cavity structure 10 in the upper structural member 1 meets certain size requirements, thereby facilitating the improvement of the structural strength and rigidity of the upper structural member 1, and reducing the space occupied by the upper structural member 1 in the luggage compartment 300, thereby facilitating the increase of the space in the luggage compartment 300 and improving the loading capacity of the luggage compartment 300. It should be noted that when the cross-sectional shape of the cavity structure 10 in the upper structural member 1 needs to meet certain size requirements, compared with other cross-sectional shapes (such as square, rectangular, etc.), the cross-sectional shape of the cavity structure 10 in the upper structural member 1 is a diamond, which is beneficial to reducing the space occupied by the upper structural member 1 in the luggage compartment 300, thereby increasing the space in the luggage compartment 300 and improving the loading capacity of the luggage compartment 300.

[0060] In some embodiments of the present invention, please combine Figures 1-4For reference, the upper structure 1 may include: an upper structure inner plate 11 and an upper structure outer plate 12, the upper structure inner plate 11 may have a first connecting flange 110, the upper structure outer plate 12 may have a second connecting flange 120, the first connecting flange 110 and the second connecting flange 120 are correspondingly connected to fix the upper structure inner plate 11 and the upper structure outer plate 12, and the upper structure inner plate 11 and the upper structure outer plate 12 jointly define the cavity structure 10.

[0061] Furthermore, if Figure 4 As shown, when the upper structure 1 is placed in the direction shown in the figure, along the height direction of the vehicle (i.e. Figure 4 ), the upper structure outer plate 12 is fixedly arranged above the upper structure inner plate 11, so that the upper structure outer plate 12 and the upper structure inner plate 11 jointly define the cavity structure 10, which is beneficial to improving the force transmission performance of the upper structure 1.

[0062] Furthermore, if Figure 4 As shown, along the height direction of the vehicle (i.e. Figure 4 The first connecting flange 110 is extended from the side of the upper structural member inner plate 11 toward the side of the storage channel 20, and the second connecting flange 120 is extended from the side of the upper structural member outer plate 12 toward the side of the storage channel 20, so that the first connecting flange 110 and the second connecting flange 120 are both arranged along the edge of the storage channel 20, thereby avoiding the first connecting flange 110 and the second connecting flange 120 from occupying the space of the passenger compartment 200 and the luggage box 300, thereby improving the utilization space of the passenger compartment 200 and the luggage box 300, and the first connecting flange 110 and the second connecting flange 120 are both arranged along the edge of the storage channel 20. The connecting flange 120 can be fixedly connected by welding or other assembly methods, so that the upper structure inner plate 11 and the upper structure outer plate 12 cooperate to form the upper structure 1. At the same time, the first connecting flange 110 and the second connecting flange 120 are fixedly connected, thereby increasing the contact area between the upper structure inner plate 11 and the upper structure outer plate 12, further improving the connection strength between the upper structure inner plate 11 and the upper structure outer plate 12, and improving the force transmission performance between the upper structure inner plate 11 and the upper structure outer plate 12, thereby achieving the effect of improving the overall stiffness and torsional stiffness of the upper structure 1.

[0063] Furthermore, if Figure 9 As shown, the upper structure inner panel 11 can have a plurality of first connecting flanges 110, and the plurality of first connecting flanges 110 are all fixedly connected to the upper structure outer panel 12, thereby further increasing the contact area between the upper structure inner panel 11 and the upper structure outer panel 12, and further improving the connection strength between the upper structure inner panel 11 and the upper structure outer panel 12, thereby achieving the effect of improving the overall stiffness and torsional stiffness of the upper structure 1, and further improving the force transmission performance between the upper structure inner panel 11 and the upper structure outer panel 12.

[0064] In some embodiments of the present invention, Figure 9 As shown, the upper structural member inner panel 11 and / or the upper structural member outer panel 12 have a first weight-reducing structure 30. This can also be understood as the upper structural member inner panel 11 having the first weight-reducing structure 30, the upper structural member outer panel 12 having the first weight-reducing structure 30, or both the upper structural member inner panel 11 and the upper structural member outer panel 12 having the first weight-reducing structure 30. Furthermore, the first weight-reducing structure 30 can be configured as a weight-reducing hole. By providing the first weight-reducing structure 30 in the upper structural member inner panel 11 and the upper structural member outer panel 12, it is beneficial to achieve a lightweight design of the upper structural member 1, reduce the mass of the body assembly 100, and thereby achieve a lightweight vehicle effect.

[0065] Furthermore, both the upper structural member inner panel 11 and the upper structural member outer panel 12 can have a plurality of first weight-reducing structures 30. By providing a plurality of first weight-reducing structures 30, the upper structural member 1 can be further designed to be lightweight, the mass of the vehicle body assembly 100 can be further reduced, and the lightweight effect of the vehicle can be further achieved.

[0066] In some embodiments of the present invention, Figure 9 As shown, the upper structure inner panel 11 and / or the upper structure outer panel 12 have reinforcements. This can also be understood as the upper structure inner panel 11 having reinforcements, the upper structure outer panel 12 having reinforcements, or both the upper structure inner panel 11 and the upper structure outer panel 12 having reinforcements. Furthermore, the reinforcements can be configured as ribs. By providing reinforcements on the upper structure inner panel 11 and the upper structure outer panel 12, the structural strength and rigidity of the upper structure inner panel 11 and the upper structure outer panel 12 are improved, thereby improving the structural strength and rigidity of the upper structure inner panel 11 and the upper structure outer panel 12, and thus improving the structural strength and rigidity of the upper structure 1.

[0067] In some embodiments of the present invention, please combine Figure 8 and Figure 9 For reference, the upper structural member outer plate 12 has a retractor mounting hole 121, which is staggered with the cavity structure 10 in the upper structural member 1. Furthermore, the vehicle's retractor is used to retract the vehicle's seat belt to achieve the effect of storing the seat belt.

[0068] like Figure 8 As shown, the upper structure inner panel 11 has a mounting avoidance hole 111 corresponding to the retractor mounting hole 121, and the body assembly 100 further includes a retractor mounting bracket 50 for mounting and fixing the retractor. The retractor mounting bracket 50 is corresponding to the mounting avoidance hole 111 of the upper structure inner panel 11. It can also be understood that Figure 6 As shown, the vehicle body assembly 100 is Figure 6 When placed in the middle direction, along the length direction of the vehicle (i.e. Figure 4), the avoidance hole 111 and the retractor mounting bracket 50 are installed in sequence, and, as shown in the X direction Figure 8 As shown, the retractor mounting hole 121 is staggered with the cavity structure 10 in the upper structural member 1, and the retractor mounting hole 121 is connected to the mounting cavity 501 defined by the retractor mounting bracket 50, so that in the process of installing and fixing the retractor, the retractor is installed and fixed in the mounting cavity 501 of the retractor mounting bracket 50 through the retractor mounting hole 121, thereby achieving the effect of installing and fixing the retractor to the retractor mounting bracket 50.

[0069] Therefore, by setting the retractor mounting hole 121 on the upper structural member outer panel 12, when removing and installing the retractor, the operator can remove and install the retractor on the retractor mounting bracket 50 from the side of the passenger compartment 200, thereby facilitating the operator to remove and install the retractor.

[0070] Furthermore, Figure 6 As shown, the retractor mounting bracket 50 is staggered with the cavity structure 10 in the upper structure 1, thereby ensuring that the cross-sectional area of ​​the cavity structure 10 in the upper structure 1 remains unchanged, thereby ensuring the structural strength and rigidity of the upper structure 1, achieving the effect of improving the overall rigidity and torsional rigidity of the upper structure 1, and further improving the force transmission performance between the upper structure inner plate 11 and the upper structure outer plate 12.

[0071] In some embodiments of the present invention, please combine Figure 1 and Figure 2 For reference, the left structural member 3 and the right structural member 4 are symmetrically arranged about the center line 13 of the upper structural member 1, and the left structural member 3 and the right structural member 4 have the same structure, so that the components constituting the left structural member 3 and the right structural member 4 can be shared, realizing the standardization of components, and is conducive to reducing the cost of designing and manufacturing molds, reducing the production cost of the body assembly 100, and thus reducing the production cost of the vehicle.

[0072] Furthermore, the left structural member 3 may include a left structural member outer panel 31 and a left structural member inner panel 32, and the right structural member 4 may include a right structural member outer panel 41 and a right structural member inner panel 42. The left structural member outer panel 31 and the right structural member outer panel 41 have the same structure, and the left structural member inner panel 32 and the right structural member inner panel 42 have the same structure. The left structural member outer panel 31 and the left structural member inner panel 32 are fixedly connected to form the left structural member 3. The left structural member outer panel 31 and the left structural member inner panel 32 jointly define the cavity structure 10 of the left structural member 3. The right structural member outer panel 41 and the right structural member inner panel 42 are fixedly connected to form the right structural member 4. The right structural member outer panel 41 and the right structural member inner panel 42 jointly define the cavity structure 10 of the right structural member 4. This helps to improve the force transmission performance of the left structural member 3 and the right structural member 4, thereby improving the force transmission performance of the vehicle body assembly 100, and also improving the structural strength and rigidity of the left structural member 3 and the right structural member 4.

[0073] In some embodiments of the present invention, Figure 1 and Figure 2 For reference, both the left structural member outer panel 31 and the right structural member outer panel 41 may have a third connecting flange 341, and both the left structural member inner panel 32 and the right structural member inner panel 42 may have a fourth connecting flange 342. The third connecting flange 341 of the left structural member outer panel 31 and the fourth connecting flange 342 of the left structural member inner panel 32 are connected to each other to secure the left structural member outer panel 31 and the left structural member inner panel 32, thereby achieving the effect of fixedly connecting the left structural member outer panel 31 and the left structural member inner panel 32 to form the left structural member 3. The third connecting flange 341 of the right structural member outer panel 41 and the fourth connecting flange 342 of the right structural member inner panel 42 are connected to each other to secure the right structural member outer panel 41 and the right structural member inner panel 42 to form the right structural member 4.

[0074] Furthermore, if Figure 1 As shown, along the width direction of the vehicle (ie Figure 1 ), the third connecting flange 341 of the left structural member outer plate 31 extends toward the storage channel 20, and the third connecting flange 341 of the right structural member outer plate 41 extends toward the storage channel 20, and, as shown Figure 2 As shown, along the width direction of the vehicle (ie Figure 2 ), the fourth connecting flange 342 of the left structural member inner panel 32 extends toward the storage channel 20, and the fourth connecting flange 342 of the right structural member inner panel 42 extends toward the storage channel 20, so that the third connecting flange 341 and the fourth connecting flange 342 both extend toward the storage channel 20, thereby avoiding the third connecting flange 341 and the fourth connecting flange 342 occupying the space of the passenger compartment 200 and the luggage compartment 300, thereby improving the utilization space of the passenger compartment 200 and the luggage compartment 300.

[0075] Furthermore, the third connecting flange 341 and the fourth connecting flange 342 of the left structural member 3 can be fixedly connected by welding or other assembly methods, so that the left structural member inner panel 32 and the left structural member outer panel 31 cooperate to form the left structural member 3. This increases the contact area between the left structural member inner panel 32 and the left structural member outer panel 31, further improving the connection strength between the left structural member inner panel 32 and the left structural member outer panel 31, thereby improving the overall stiffness and torsional stiffness of the left structural member 3. At the same time, the third connecting flange 341 and the fourth connecting flange 342 of the right structural member 4 are fixedly connected, increasing the contact area between the right structural member outer panel 41 and the right structural member inner panel 42, further improving the connection strength between the right structural member outer panel 41 and the right structural member inner panel 42, thereby improving the overall stiffness and torsional stiffness of the right structural member 4.

[0076] In some embodiments of the present invention, please combine Figure 1 and Figure 2 For reference, the vehicle body assembly 100 may further include: an upper joint 5 and a lower joint 6, wherein the left structural member 3 and the right structural member 4 are both connected to the upper structural member 1 via the upper joint 5, and the left structural member 3 and the right structural member 4 are both connected to the lower structural member 2 via the lower joint 6. Furthermore, the upper joint 5 and the lower joint 6 may be multiple, such as Figure 1 As shown, the present application is described by taking the vehicle body component 100 having two upper joints 5 and two lower joints 6 as an example.

[0077] like Figure 1 As shown, along the length direction of the vehicle (i.e. Figure 1 ), the two upper joints 5 are respectively fixedly connected to the two ends of the upper structural member 1, and the two upper joints 5 are also respectively fixedly connected to the left structural member 3 and the right structural member 4, thereby achieving the effect of fixed connection between the upper structural member 1 and the left structural member 3 and the right structural member 4. The two lower joints 6 are respectively fixedly connected to the two ends of the lower structural member 2, and the two lower joints 6 are fixedly connected to the left structural member 3 and the right structural member 4, thereby achieving the effect of fixed connection between the lower structural member 2 and the left structural member 3 and the right structural member 4, thereby achieving the effect of fixed connection between the upper structural member 1, the lower structural member 2, the left structural member 3 and the right structural member 4, thereby achieving the effect of connecting the upper structural member 1, the lower structural member 2, the left structural member 3 and the right structural member 4 together to form a closed ring structure, thereby improving the structural strength and rigidity of the body assembly 100, which is conducive to improving the handling stability of the vehicle. The body assembly 100 has good force transmission performance, preventing the risk of stress concentration in the body assembly 100, which is conducive to reducing road load excitation, improving the vehicle's NVH performance, and thus enhancing the comfort perception experience of the driver and passengers.

[0078] Furthermore, at least one of the plurality of upper joints 5 and the plurality of lower joints 6 has a cavity therein, and at least a portion of the cavity has a cavity structure 10 of equal cross-sectional area. Furthermore, preferably, the plurality of upper joints 5 and the plurality of lower joints 6 all have cavities, so that when the upper joint 5 connects the upper structural member 1 and the left structural member 3, or the upper structural member 1 and the right structural member 4, and when the lower joint 6 connects the lower structural member 2 and the left structural member 3, or the lower structural member 2 and the right structural member 4, the upper structural member 1, the lower structural member 2, the left structural member 3, the right structural member 4, the upper joint 5 and the lower joint 6 jointly define a continuous cavity, so that the force transmission effect between the upper structural member 1, the lower structural member 2, the left structural member 3, the right structural member 4, the upper joint 5 and the lower joint 6 is better, thereby improving the force transmission performance of the body assembly 100 and preventing the risk of stress concentration in the body assembly 100.

[0079] Furthermore, a "trumpet-shaped" connection structure can be adopted at the connection between the upper joint 5 and the upper structural member 1. It can also be understood that when the upper joint 5 is fixedly connected to the upper structural member 1, the connection between the upper joint 5 and the upper structural member 1 is constructed as a "trumpet-shaped" structure. Along the direction from the upper joint 5 to the upper structural member 1, the cross-sectional area of ​​the cavity of the upper joint 5 gradually increases or decreases, so as to prevent the cross-sectional area of ​​the cavity at the connection between the upper joint 5 and the upper structural member 1 from changing suddenly when the upper joint 5 is fixedly connected to the upper structural member 1, thereby improving the force transmission performance of the connection between the upper joint 5 and the upper structural member 1, thereby improving the NVH performance of the vehicle and enhancing the comfort perception experience of the driver and passengers.

[0080] Furthermore, the connection between the upper joint 5 and the left structural member 3, and the connection between the upper joint 5 and the right structural member 4 both adopt a "trumpet-shaped" connection structure, thereby preventing the cross-sectional area of ​​the cavity at the connection between the upper joint 5 and the left structural member 3 from suddenly changing, preventing the cross-sectional area of ​​the cavity at the connection between the upper joint 5 and the right structural member 4 from suddenly changing, improving the force transmission performance of the connection between the upper joint 5 and the left structural member 3, improving the force transmission performance of the connection between the upper joint 5 and the right structural member 4, further improving the vehicle's NVH performance, and enhancing the comfort perception experience of the driver and passengers.

[0081] Furthermore, please combine Figure 1 and Figure 2 For reference, the lower joint 6 is overlapped between the left structural member 3 and the lower structural member 2, and the lower joint 6 can be installed and fixed to the left structural member 3 and the lower structural member 2 by welding, thereby achieving the effect of connecting the left structural member 3 and the lower structural member 2. The lower joint 6 is overlapped between the right structural member 4 and the lower structural member 2, and the lower joint 6 can be installed and fixed to the right structural member 4 and the lower structural member 2 by welding, thereby achieving the effect of connecting the right structural member 4 and the lower structural member 2.

[0082] In some embodiments of the present invention, the upper joint 5 may include an upper joint outer plate 51 and an upper joint inner plate 52. Figure 1 and Figure 2 For reference, the upper joint outer plate 51 and the upper joint inner plate 52 are fixedly connected to form the upper joint 5. The upper joint outer plate 51 and the upper joint inner plate 52 jointly define the cavity of the upper joint 5, which is beneficial to improving the force transmission performance of the upper joint 5 and further improving the force transmission performance of the body assembly 100.

[0083] In some embodiments of the present invention, Figure 4As shown, the upper joint 5 and / or the lower joint 6 may have a second weight-reducing structure 40. This can also be understood as the upper joint 5 having the second weight-reducing structure 40, the lower joint 6 having the second weight-reducing structure 40, or both the upper joint 5 and the lower joint 6 having the second weight-reducing structure 40. Furthermore, the second weight-reducing structure 40 may be configured as a weight-reducing hole. By providing the first weight-reducing structure 30 on the upper joint 5 and the lower joint 6, it is advantageous to achieve a lightweight design of the upper joint 5 and the lower joint 6, reduce the mass of the body assembly 100, and thereby achieve a lightweight vehicle effect.

[0084] Furthermore, both the upper joint 5 and the lower joint 6 can have multiple second weight-reducing structures 40. By setting up multiple second weight-reducing structures 40, the upper joint 5 and the lower joint 6 can be further designed to be lightweight, the mass of the body assembly 100 can be further reduced, and the lightweight effect of the vehicle can be further achieved.

[0085] In some embodiments of the present invention, Figure 1 As shown, both the left structural member 3 and the right structural member 4 may have a latch mounting position 60. The latch is used to lock and unlock the rear seats.

[0087] Furthermore, both the left structural member 3 and the right structural member 4 can have a first welding edge 71, so as to increase the welding area between the left structural member 3 and the left wheel cover 7, and increase the welding area between the right structural member 4 and the right wheel cover 8 when the left structural member 3 and the right structural member 4 are respectively installed and fixed to the left wheel cover 7 and the right wheel cover 8, thereby reducing the risk of separation between the left structural member 3 and the left wheel cover 7, and reducing the risk of separation between the right structural member 4 and the right wheel cover 8, thereby helping to improve the overall stiffness and torsional stiffness between the left structural member 3, the right structural member 4 and the wheel cover, and improve the force transmission performance between the left structural member 3, the right structural member 4 and the wheel cover, further improving the vehicle NVH performance, and further enhancing the comfort perception experience of the driver and passengers.

[0088] In some embodiments of the present invention, Figure 6As shown, the vehicle body assembly 100 may further include a shock absorber mount 9, which is fixed to the wheel housing and adapted to be connected to the vehicle's longitudinal beam 400. The shock absorber mount 9 has a shock absorber mounting hole 90. In the width direction of the vehicle, the shock absorber mounting hole 90 corresponds to the cavity structure 10 within the corresponding left structural member 3 or right structural member 4. It should be noted that both the left wheel housing 7 and the right wheel housing 8 may be provided with a shock absorber mount 9.

[0089] Furthermore, there can be multiple shock absorber seats 9.

[0090] Moreover, when the shock absorber seat 9 is installed and fixed to the wheel arch, the shock absorber seat 9 is also fixedly connected to the longitudinal beam 400. The force applied by the shock absorber to the shock absorber seat 9 (for example, the road load applied to the shock absorber during driving of the vehicle) can be transmitted to the wheel arch and the longitudinal beam 400, thereby achieving the effect of dispersing the force and preventing stress from concentrating on the shock absorber seat 9, which is beneficial to reducing road load excitation, improving the NVH performance of the vehicle, and thereby enhancing the comfort perception experience of the driver and passengers.

[0091] like Figure 6 As shown, the edge of the shock absorber seat 9 has a second welding edge 72, so as to increase the welding area between the shock absorber seat 9 and the corresponding wheel cover and longitudinal beam 400 when the shock absorber seat 9 is fixedly connected to the corresponding wheel cover and longitudinal beam 400, reduce the risk of separation between the shock absorber seat 9 and the corresponding wheel cover and longitudinal beam 400, and thus help to improve the overall stiffness and torsional stiffness between the shock absorber seat 9 and the corresponding wheel cover and longitudinal beam 400, and improve the force transmission performance between the shock absorber seat 9 and the corresponding wheel cover and longitudinal beam 400, further improve the NVH performance of the vehicle, and further enhance the comfort perception experience of the driver and passengers.

[0092] Furthermore, please combine Figure 6 and Figure 7 For reference, the shock absorber seat 9 has a plurality of shock absorber mounting holes 90 , and the plurality of shock absorber mounting holes 90 are used to fix and assemble the shock absorber, thereby achieving the effect of the shock absorber being installed and fixed to the shock absorber seat 9 .

[0093] Furthermore, please combine Figure 6 and Figure 7 For reference, the example of the shock absorber seat 9 being fixed to the right wheel housing 8 is used for explanation. Figure 6), at least one of the multiple shock absorber mounting holes 90 corresponds to the cavity structure 10 in the right structural member 4, so that in the width direction of the vehicle, the shock absorber mounting hole 90 corresponds to the cavity structure 10 in the right structural member 4, so that the force applied by the shock absorber to the shock absorber seat 9 can be transmitted along the right structural member 4 to other components of the body assembly 100 (for example, the upper structural member 1, the lower structural member 2, the left structural member 3, the upper joint 5 and the lower joint 6, etc.), thereby achieving the effect of dispersing the force applied by the shock absorber to the shock absorber seat 9, preventing stress from concentrating on the shock absorber seat 9, solving the support stiffness problem of the shock absorber seat 9, and improving the static stiffness and dynamic stiffness of the shock absorber mounting hole 90 of the shock absorber seat 9 in all directions, which is conducive to reducing road load excitation, improving vehicle NVH performance, and thus enhancing the comfort perception experience of the driver and passengers, and is conducive to improving the handling stability of the vehicle. It should be noted that, according to the above description, when the shock absorber seat 9 is installed and fixed to the left wheel cover 7, the above effects can also be achieved, so they will not be described in detail.

[0094] In some embodiments of the present invention, Figure 6 As shown, the shock absorber seat 9 has a seat body 91 and a plurality of shock absorber seat reinforcement plates 92. The seat body 91 is used to install the shock absorber, and the plurality of shock absorber seat reinforcement plates 92 are connected between the seat body 91 and the longitudinal beam 400. Furthermore, the seat body 91 and the shock absorber seat reinforcement plates 92 can be integrally formed, thereby improving the structural strength of the shock absorber seat 9 and reducing the risk of separation between the seat body 91 and the shock absorber seat reinforcement plates 92. Figure 6 As shown, the seat body 91 is provided with a shock absorber mounting hole 90 , thereby achieving the effect of fixing the shock absorber to the shock absorber seat 9 .

[0095] Furthermore, if Figure 6As shown, the present application is explained by taking the shock absorber seat 9 having two shock absorber seat reinforcement plates 92 as an example, but the present application is not limited thereto. The shock absorber seat 9 may have three, four, or five shock absorber seat reinforcement plates 92. By arranging the shock absorber seat 9 to have two shock absorber seat reinforcement plates 92, and the two shock absorber seat reinforcement plates 92 are both connected between the seat body 91 and the longitudinal beam 400, when the shock absorber is fixedly assembled to the shock absorber seat 9 and the longitudinal beam 400, the seat body 91, the two shock absorber seat reinforcement plates 92 and the longitudinal beam 400 form a "triangle" structural layout, which is beneficial to improving the structural strength of the seat body 91, the two shock absorber seat reinforcement plates 92 and the longitudinal beam 400, and the force exerted by the shock absorber on the seat body 91 can be transmitted along the two shock absorber seat reinforcement plates 92. The force is transmitted to the longitudinal beam 400, which is conducive to uniformly and quickly dispersing the force to the longitudinal beam 400, further preventing stress concentration on the shock absorber seat 9, solving the support stiffness problem of the shock absorber seat 9, and further improving the static stiffness and dynamic stiffness of the shock absorber mounting hole 90 of the shock absorber seat 9 in all directions, thereby further helping to reduce road load excitation and noise transmitted to the vehicle body through the local vibration of the wheel cover, further improving the vehicle's NVH performance, enhancing the comfort perception experience of the driver and passengers, and helping to improve the vehicle's handling stability.

The floor cross member 21 and the vehicle body floor 22 jointly define a cavity structure 10, which is beneficial to improving the force transmission performance of the lower structure 2, preventing the risk of stress concentration in the lower structure 2, and is beneficial to reducing road load excitation, improving the vehicle's NVH performance, and thereby enhancing the comfort perception experience of the driver and passengers.

[0097] Furthermore, the floor cross member 21 may have a third welding edge 73, so that when the floor cross member 21 is fixedly connected to the vehicle body floor 22, the welding area between the floor cross member 21 and the vehicle body floor 22 is increased, thereby reducing the risk of separation between the floor cross member 21 and the vehicle body floor 22. This is beneficial for improving the overall stiffness and torsional stiffness between the floor cross member 21 and the vehicle body floor 22, as well as improving the force transmission performance between the floor cross member 21 and the vehicle body floor 22, further improving the vehicle's NVH performance, and further enhancing the comfort perception experience of the driver and passengers.
