Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and in particular to a vehicle body and a vehicle having the same. Background Art

[0002] In the existing technology, the rear shock absorber support and rear wheel cover assembly of the load-bearing body are the hard points connecting the chassis and the body. During the vehicle's driving, the road excitation is transmitted to the rear wheel cover area structure through the shock absorber. When the vehicle passes through a bumpy road section, the shock absorber support is more likely to produce abnormal noise, affecting the quality of the entire vehicle. Therefore, the structure at the rear wheel cover is required to have higher rigidity.

[0003] In the current traditional vehicle body design structure, the rear shock absorber support, rear wheel cover, and rear wheel cover reinforcement plate are welded. When they are combined with the floor longitudinal beam, the connection strength between the rear shock absorber support and the rear floor longitudinal beam is weak, the cross-section is discontinuous, and the contribution to rigidity is very small. The force transmission is not smooth, and cracking and abnormal noise problems are more likely to occur. In addition, the support parts occupy the volume of the trunk. Since the trunk trim panel has a relatively regular shape, in order to avoid the oblique support parts, the entire trunk cover needs to be raised to avoid them, which greatly sacrifices the trunk space.

DETAILED DESCRIPTION

[0043] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0044] The following will refer to the attached Figure 1-15 The present invention is described in detail with reference to the embodiments.

[0045] The present invention is described with the X direction as the longitudinal direction of the vehicle (i.e., the front-rear direction of the vehicle), the Y direction as the lateral direction of the vehicle (i.e., the left-right direction of the vehicle), and the Z direction as the vertical direction of the vehicle (i.e., the up-down direction of the vehicle).

[0046] like Figure 1 and Figure 2 As shown, the vehicle body 100 according to an embodiment of the present invention includes an upper vehicle body 1 and a lower vehicle body 2 , which are combined and spliced ​​together, wherein the upper vehicle body 1 includes a D-pillar assembly 11 , a wheel cover assembly 12 , and a side window assembly 13 .

[0047] The D-pillar assembly 11 is located at the direct connection between the roof and the vehicle compartment at the rear of the vehicle body 100, and includes: an upper D-pillar inner panel section 111, a lower D-pillar inner panel section 112, and a D-pillar reinforcement plate 113; the D-pillar assembly 11 plays an important role in the overall shape and layout of the vehicle, and is the main part supporting the structural strength of the vehicle. The higher its strength, the stronger the impact resistance of the vehicle body 100.

[0048] The wheel cover assembly 12 includes a wheel cover inner panel 121. The wheel cover is connected to the shock absorber 200 support to form a cavity structure and is connected to the upper structure. The upper part of the wheel cover reinforcement plate is connected to the D-pillar. Under the torsional working condition of the vehicle body 100, part of the load received by the shock absorber 200 support is transmitted to the D-ring. By dispersing the load through multiple paths, the torsional stiffness of the vehicle body 100 can be improved.

[0049] The side window assembly 13 includes a side window inner panel 131 and a side window reinforcement panel 132. The side window assembly 13 is connected to the D-pillar assembly 11 and the wheelhouse assembly 12, respectively, and together with the D-pillar assembly 11 and the wheelhouse assembly 12, forms a first cavity 10 extending longitudinally. This integrated connection design ensures that the vehicle upper body 1 has excellent structural stability, smooth force transmission, and is less prone to cracking and abnormal noise, thereby enhancing the vehicle's stability and sustainability.

[0050] In some examples, the side window assembly 13 , the D-pillar assembly 11 , and the wheel arch assembly 12 may be connected by three-layer spot welding, thereby further enhancing the structural stability of the side window assembly 13 .

[0051] The lower vehicle body 2 includes a rear longitudinal beam assembly 21 and a shock absorber support assembly, wherein the rear longitudinal beam assembly 21 includes a rear longitudinal beam 211, a rear longitudinal beam reinforcement plate 212 and a rear longitudinal beam support bracket 213. The longitudinal beam support bracket is arranged above the rear longitudinal beam reinforcement plate 212. The rear longitudinal beam assembly 21 is connected to the wheel house assembly 12, thereby realizing the integrity and smoothness of the connection of the vehicle body 100, and also improving the overall torsional stiffness of the vehicle body 100.

[0052] The shock absorber support assembly includes a support body 221 and a support reinforcement plate 222. The shock absorber support is connected to the rear longitudinal beam assembly 21. The shock absorber support is welded to the outer side of the rear longitudinal beam 211, and the shock absorber support assembly and the rear longitudinal beam assembly 21 form a second cavity 20. The second cavity 20 is connected to the first cavity 10, thus forming a complete rear wheel cover of the vehicle body 100 and the rear structure of the vehicle, improving the strength and rigidity of the connection, solving the problem of insufficient connection rigidity of the vehicle body 100 and the problem of the rear luggage compartment volume being occupied by the reinforced structure, increasing the usable space of the vehicle trunk, and also making the vehicle body 100 more solid.

[0053] According to the vehicle body 100 of the present invention, the torsional stiffness of the entire vehicle body 100 is improved by providing an upper vehicle body 1 and a lower vehicle body 2, and the first cavity 10 formed in the upper vehicle body 1 and the second cavity 20 formed in the lower vehicle body 2 allow the lower structure and the upper structure to penetrate. Under the torsional working condition of the vehicle body 100, part of the load borne by the shock absorber 200 support is transmitted to the D-ring, and the torsional stiffness of the vehicle body 100 is improved by dispersing the load through multiple paths.

[0054] In some embodiments, as Figure 6 and Figure 7 As shown, the rear longitudinal beam assembly 21 includes: a rear longitudinal beam 211 and a rear longitudinal beam reinforcement plate 212. The rear longitudinal beam 211 is provided with a third cavity. The rear longitudinal beam reinforcement plate 212 is provided in the third cavity and has the same shape as the cavity of the rear longitudinal beam 211. It is fitted with the inner wall of the rear longitudinal beam 211, thereby improving the connection effect of the overall rear longitudinal beam assembly 21 and strengthening the structural strength of the rear longitudinal beam assembly 21.

[0055] In some embodiments, as Figure 6 As shown, the rear longitudinal beam 211 includes a rear longitudinal beam body 25 and a rear longitudinal beam cover plate 26. The rear longitudinal beam body 25 is formed with an upwardly open groove, and the rear longitudinal beam reinforcement plate 212 is provided in the groove. Figure XAs shown, the upwardly open groove formed by the rear longitudinal beam body 25 has a U-shaped cross-section, so that the rear longitudinal beam reinforcement plate 212 can fit tightly against the inner wall of the groove. That is, the bottom wall and two opposing side walls of the rear longitudinal beam reinforcement plate 212 are welded to the bottom and side surfaces of the rear longitudinal beam 211, ensuring the stability of the rear longitudinal beam assembly 21 and enhancing the strength of the rear longitudinal beam assembly 21. The rear longitudinal beam cover plate 26 is provided at the open end of the rear longitudinal beam body 25, that is, the rear longitudinal beam cover plate 26 is provided at the upper end of the rear longitudinal beam body 25 and is connected to the rear longitudinal beam body 25. The rear longitudinal beam cover plate 26 and the rear longitudinal beam body 25 form a third cavity, and the rear longitudinal beam cover plate 26 is provided with a connecting flap extending upward and corresponding to the support reinforcement plate 222. In some examples, on the inside of the vehicle, the rear longitudinal beam cover plate 26 is welded to the rear longitudinal beam 211 flange. On the outside of the vehicle, the flange of the rear longitudinal beam cover plate 26 is welded to the side wall of the left rear longitudinal beam 211 and the area corresponding to the shock absorber 200 support to form a three-layer weld, thereby directly connecting the shock absorber 200 support and the floor longitudinal beam as a whole, while also improving the torsional rigidity of the entire vehicle body 100. The rear longitudinal beam cover plate 26 also has raised reinforcing ribs arranged transversely to the vehicle in the shock absorber 200 support area, which are used to connect to the lateral opening of the longitudinal beam. This can significantly increase the lateral rigidity of the shock absorber 200 support, giving the rear longitudinal beam cover plate 26 greater strength to maintain the stability of the entire structure.

[0056] In some examples, such as Figure 6 As shown, the rear longitudinal beam cover plate 26 is provided with a plurality of reinforcing ribs, all of which extend in the transverse direction and are arranged at intervals in the longitudinal direction. In some specific examples, three reinforcing ribs are provided. Of course, the number of reinforcing ribs is not limited thereto and can be arranged accordingly according to the specific settings.

[0057] In some embodiments, as Figure 5 and Figure 12 As shown, the rear longitudinal beam assembly 21 also includes a rear longitudinal beam support bracket 213. The rear longitudinal beam support bracket 213 is arranged in a groove formed by the rear longitudinal beam reinforcement plate 212 and the rear longitudinal beam main body 25, and is arranged above the rear longitudinal beam reinforcement plate 212. The rear longitudinal beam support bracket 213 is laterally connected between the two opposite inner side walls of the rear longitudinal beam main body 25. Therefore, by providing the rear longitudinal beam support bracket 213, the structural strength of the rear longitudinal beam assembly 21 can be further improved, and the rear longitudinal beam assembly 21 can be prevented from being deformed in the lateral direction.

[0058] In some examples, such as Figure 12As shown, the rear longitudinal beam support bracket 213 is welded to the two sidewalls of the rear longitudinal beam 211 above the rear longitudinal beam reinforcement plate 212. That is, the welded surface of the rear longitudinal beam support bracket 213, which is closest to the vehicle's exterior, is connected to the rear longitudinal beam 211 and the rear shock absorber 200 support by three layers of welding. Simultaneously, the lower rear longitudinal beam 211, the rear longitudinal beam reinforcement plate 212, and the rear shock absorber 200 support are also connected by three layers of welding. This allows the longitudinal beam support bracket, located at a position corresponding to the shock absorber 200 support within the inner cavity of the rear longitudinal beam 211, to transmit lateral loads to the shock absorber 200 support, thereby improving lateral stiffness.

[0059] In some embodiments, as Figure 5 、 6 As shown in Figures 8 and 15, the shock absorber support assembly includes a support body 221 and a support reinforcement plate 222. The support body 221 is welded to the outside of the rear longitudinal beam 211, forming two cavity structures therewith, and is connected to the side walls of the rear longitudinal beam 211. The support reinforcement plate 222 is provided on the inside of the support body 221 and is connected to the support body 221 and the rear longitudinal beam 211, respectively.

[0060] Thus, the two hollow structures formed by the support body 221 and the support reinforcement plate 222 form at least a portion of the second cavity 20. The provision of the two hollow cavities ensures that a hollow structure is formed there and that the structural strength of the region is ensured. Specifically, the bent structure between the two hollow structures enhances strength. Furthermore, the provision of the support reinforcement plate 222 enhances the strength of the support of the shock absorber 200.

[0061] In some examples, the support body 221 , the support reinforcement plate 222 , and the rear longitudinal beam 211 may be connected by three-layer welding, thereby improving the overall strength of the shock absorber 200 support and ensuring the connection strength among the three.

[0062] In some embodiments, as Figure 8 、 Figure 9 As shown, the support body 221 is provided with a first protrusion 223, which protrudes outward and extends longitudinally to form a first sub-cavity 23 open to the inside; in some examples, such as Figure X As shown, the height of the first raised portion gradually increases from bottom to top. The support reinforcement plate 222 is provided with a second raised portion 224, which rises inward and forms a second sub-cavity 24 that is open to the outside and arranged opposite the first sub-cavity 23. The support body 221, the support reinforcement plate 222, and the outer sidewall of the rear longitudinal beam 211 cooperate to form the second cavity 20.

[0063] As a result, the first sub-cavity 23 is open inward and the second sub-cavity 24 is open outward. In some examples, the first sub-cavity 23 and the second sub-cavity 24 are connected, and since the outer side wall of the support body 221, the support reinforcement plate 222 and the rear longitudinal beam 211 cooperate to form the second cavity 20, the first sub-cavity 23 and the second sub-cavity 24 are connected, and the first sub-cavity 23 and the second sub-cavity 24 are connected with the second cavity 20, forming a cavity structure at the support of the shock absorber 200.

[0064] In some embodiments, as Figure 8 As shown, there are two first raised portions 223, and the two first raised portions 223 are arranged at intervals in the X direction (the front and rear direction of the vehicle); there are two second raised portions 224, and the upper ends of the two second raised portions 224 are connected, and the upper parts of the two second sub-cavities 24 are connected.

[0065] In some examples, the two first protrusions 223 are respectively arranged opposite to the two second protrusions 224, that is, one of the first protrusions 223 is open to one of the second protrusions 224, and the other first protrusion 223 is open to the other second protrusion 224, thereby making the two first cavities 10 and the two second cavities 20 respectively arranged correspondingly.

[0066] Therefore, at the support of the shock absorber 200, the two first sub-cavities 23 and the two sub-cavities are respectively arranged to form two cavity structures, and the two cavity structures are connected to the second cavity body 20. In some examples, the support reinforcement plate 222 is connected to the upper half of the support body 221. Therefore, the first sub-cavity 23 and the second sub-cavity 24 are arranged at the upper part of the shock absorber 200 support.

[0067] As a result, the two cavities in the upper part of the shock absorber support reinforcement plate 222 gradually transition into a large cavity. This structural design allows the shock absorber to absorb the energy of vibration transmitted from the wheels due to uneven road surface, thereby increasing ride comfort and better ensuring vehicle smoothness, handling stability and other driving performance.

[0068] In some embodiments, as Figure 3 As shown, the wheelhouse assembly 12 includes a wheelhouse inner panel 121, which is provided with a mounting groove and a sunken platform 122 that protrudes outward. The sunken platform 122 is correspondingly arranged and connected to a portion of the support body 221. The sunken platform 122 is used to connect the support body 221 to the wheelhouse inner panel 121. The shape of the sunken platform 122 matches the edge profile of the shock absorber 200 support reinforcement plate 222, so that the support body 221 can better fit and connect with the sunken platform 122.

[0069] In some examples, the support body 221, the support reinforcement plate 222 and the sink 122 are welded in three layers to enhance the connection strength therein.

[0070] In some examples, such as Figure 8 As shown, the upper edge of the support reinforcement plate 222 is higher than the upper edge of the support body 221 , so that the upper edge of the support reinforcement plate 222 is convenient for overlapping and connecting with the side window reinforcement plate 132 .

[0071] In some embodiments, as Figure 3 、 Figure 4 As shown, the side window assembly 13 includes a side window inner panel 131 and a side window reinforcement panel 132. The side window reinforcement panel 132 is disposed inside the side window inner panel 131 and is bulged inward. The upper end of the side window reinforcement panel 132 is connected to the D-pillar assembly 11, and the lower end of the side window reinforcement panel 132 is connected to the wheelhouse inner panel 121, forming a first cavity 10. Thus, the side window reinforcement panel 132 not only serves to enhance the structural strength of the upper body 1 at the side window, but also, together with the side window inner panel 131, forms the first cavity 10, connecting the upper and lower parts of the vehicle body 100. Vibration from the wheels is transmitted to the vehicle window through the interconnected cavity structure, further transferring a portion of the load borne by the shock absorber 200 support to the D-ring. This multi-path load distribution improves the torsional rigidity of the vehicle body 100.

[0072] In some embodiments, as Figure 3 、 Figure 4 As shown, the lower portion of the side window reinforcement plate 132 extends downward in a gradually expanding shape and is formed with an overlapping flange 133. The overlapping flange 133 is connected to the support reinforcement plate 222, thereby realizing the connection between the upper body 1 and the lower body 2. In addition, the gradually expanding shape of the side window reinforcement plate 132 can increase the connection area between the side window reinforcement plate 132 and the support reinforcement plate 222. In some examples, the overlapping flange 133 is welded to the support reinforcement plate 222 after overlapping.

[0073] In some embodiments, in the X direction (i.e., the longitudinal direction of the vehicle), the connection length between the support body 221 and the rear longitudinal beam 211 is L1, where the length of the rear longitudinal beam 211 is L, and the relationship L1 > 1 / 2L is satisfied. Thus, the shock absorber 200 support and the longitudinal beam are welded together to form a single unit. This connection area ensures that the shock absorber 200 mounting point has very high rigidity in all three directions: X, Y, and Z. This prevents abnormal noise and cracking caused by poor stiffness of the shock absorber 200 support under harsh operating conditions.

[0074] In some embodiments, as Figure 3 、 Figure 4As shown, the D-pillar assembly 11 includes: a D-pillar inner panel upper section 111, a D-pillar inner panel lower section 112 and a D-pillar reinforcement plate 113, wherein the D-pillar inner panel upper section 111 is connected to the side window assembly 13, the upper end of the D-pillar inner panel lower section 112 is connected to the D-pillar inner panel upper section, and extends from top to bottom and rearward to the side away from the side window assembly 13, and the D-pillar reinforcement plate 113 is arranged on the outer sides of the D-pillar inner panel upper section 111 and the D-pillar inner panel lower section 112, and is respectively connected to the D-pillar inner panel upper section 111 and the D-pillar inner panel lower section 112. The D-pillar assembly 11 formed by the D-pillar inner panel upper section 111, the D-pillar inner panel lower section 112 and the D-pillar reinforcement has good structural strength and the vibration from the shock absorber support assembly 22 can be transmitted to the D-pillar inner panel lower section 112, the D-pillar reinforcement plate 113 and the D-pillar inner panel upper section 111 through the wheel cover assembly 12 and the side window assembly 13 in sequence. Part of the load received by the shock absorber 200 support is transmitted to various parts of the D ring, and the load is dispersed through multiple paths, thereby improving the torsional stiffness of the vehicle body 100.

[0075] In some embodiments, as Figure 3 As shown, the vehicle body 100 also includes a partition panel 3, which is arranged along the X-direction. The front end of the partition panel 3 is connected to the side window assembly 13, and the rear end of the partition panel 3 is connected to the lower section of the D-pillar inner panel 112. As a result, the partition panel 3, the side window assembly 13, and the lower section of the D-pillar inner panel 112 form a triangular frame support structure, further enhancing the overall strength of the structure.

[0076] According to the present invention, a vehicle is further provided, comprising the vehicle body 100 according to any one of the embodiments of the present invention.
