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 prior art, 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 driving of the vehicle, 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 body design structure, the rear shock absorber support, rear wheel cover, and rear wheel cover reinforcement plate are welded. When they are assembled with the floor longitudinal beam, the connection strength between the rear shock absorber support and the rear floor longitudinal beam is weak and the cross-section is discontinuous, which contributes little to the rigidity, resulting in poor force transmission and more prone to cracking and abnormal noise problems. In addition, the support parts occupy the volume of the trunk. Since the trunk trim panel has a relatively regular shape, the entire trunk cover needs to be raised to avoid the oblique support parts, resulting in a large sacrifice of 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 embodiments.

[0045] The present invention describes the embodiments of the present invention 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 the embodiment of the present invention includes an upper vehicle body 1 and a lower vehicle body 2 , and the upper vehicle body 1 and the lower vehicle body 2 are combined and spliced, 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 compartment at the rear of the vehicle body 100, and includes: an upper section of the D-pillar inner panel 111, a lower section of the D-pillar inner panel 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 arch assembly 12 includes a wheel arch inner plate 121. The wheel arch 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 arch reinforcement plate is connected to the D-pillar. Under the torsional 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 plate 131 and a side window reinforcement plate 132. The side window assembly 13 is connected to the D-pillar assembly 11 and the wheel cover assembly 12 respectively, and together with the D-pillar assembly 11 and the wheel cover assembly 12, forms a first cavity 10 extending in the longitudinal direction. Through this integral connection design, the vehicle body 1 can have good structural stability, smooth force transmission, and is not prone to cracking and abnormal noise problems, thereby increasing the stability and sustainability of the vehicle.

[0050] In some examples, the side window assembly 13 , the D-pillar assembly 11 , and the wheel cover assembly 12 are connected and 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, and the rear longitudinal beam assembly 21 is connected to the wheel cover 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, thereby 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 that the volume of the rear luggage compartment of the vehicle is occupied by the reinforced structure, increasing the usable space of the vehicle trunk, and also making the vehicle body 100 more sturdy.

[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 to be connected with the upper structure. Under the torsional condition of the vehicle body 100, a part of the load received 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, 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 arranged 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, 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 a groove open upward, and the rear longitudinal beam reinforcement plate 212 is arranged in the groove. Figure XAs shown, the groove section formed by the rear longitudinal beam body 25 and open upward is U-shaped, so that the rear longitudinal beam reinforcement plate 212 can fit closely with the inner wall of the groove, that is, the bottom wall and two opposite side walls of the rear longitudinal beam reinforcement plate 212 are welded to the bottom and side of the rear longitudinal beam 211, which ensures the stability of the rear longitudinal beam assembly 21 and enhances the strength of the rear longitudinal beam assembly 21. The rear longitudinal beam cover plate 26 is arranged at the open end of the rear longitudinal beam body 25, that is, the rear longitudinal beam cover plate 26 is arranged at the upper end of the rear longitudinal beam body 25 and 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 connection 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, and on the outside of the vehicle, the flange of the rear longitudinal beam cover plate 26 forms a three-layer welding with the side wall of the left rear longitudinal beam 211 and the corresponding area of ​​the shock absorber 200 support, so that the shock absorber 200 support and the floor longitudinal beam are directly connected as a whole, and the torsional rigidity of the entire vehicle body 100 is also improved. In addition, the rear longitudinal beam cover plate 26 is provided with a raised reinforcing rib arranged transversely in the vehicle in the shock absorber 200 support area, which is used to connect the lateral opening of the longitudinal beam, which can greatly improve the lateral rigidity of the shock absorber 200 support, so that the rear longitudinal beam cover plate 26 has better 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, Figure 5 and Fig.12 As shown, the rear longitudinal beam assembly 21 also includes a rear longitudinal beam support bracket 213, which is arranged in a groove formed by the rear longitudinal beam reinforcement plate 212 and the rear longitudinal beam body 25, and is arranged above the rear longitudinal beam reinforcement plate 212. The rear longitudinal beam support bracket 213 is laterally connected between two opposite inner side walls of the rear longitudinal beam body 25. Therefore, by arranging 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 Fig.12As shown, the rear longitudinal beam support bracket 213 is welded to the two side walls of the rear longitudinal beam 211 at the upper part of the rear longitudinal beam reinforcement plate 212, that is, the welding surface of the rear longitudinal beam support bracket 213 close to the outer side of the vehicle is connected to the rear longitudinal beam 211 and the rear shock absorber 200 support by three layers of welding, and at the same time, 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. In this way, the longitudinal beam support bracket at the position corresponding to the shock absorber 200 support in the inner cavity of the rear longitudinal beam 211 can transmit the lateral load on the shock absorber 200 support, thereby improving the lateral stiffness.

[0059] In some embodiments, Figure 5 , 6 As shown in FIGS. 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 and forms two cavity structures therewith, and is connected to the side wall of the rear longitudinal beam 211. The support reinforcement plate 222 is arranged on the inner side of the support body 221 and is connected to the support body 221 and the rear longitudinal beam 211, respectively.

[0060] Thus, the two cavity structures formed by the support body 221 and the support reinforcement plate 222 form at least part of the second cavity 20, and the two cavities can ensure that a cavity structure is formed there, and the structural strength of the place can be ensured, that is, the bending structure between the two cavity structures can achieve the effect of enhancing strength. And the setting of the support reinforcement plate 222 can enhance the strength of the shock absorber 200 support.

[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, so as to improve the overall strength of the shock absorber 200 support and ensure the connection strength among the three.

[0062] In some embodiments, Figure 8 , Fig. 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 is raised inwardly and forms a second sub-cavity 24 which is open to the outside and arranged opposite to the first sub-cavity 23; the support body 221, the support reinforcement plate 222 and the outer side wall of the rear longitudinal beam 211 cooperate to form the second cavity 20.

[0063] Thus, the first sub-cavity 23 opens inwardly, and the second sub-cavity 24 opens outwardly. 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, 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, the two first cavities 10 and the two second cavities 20 are 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 correspondingly 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, and thus, 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 conditions, thereby increasing riding comfort and better ensuring vehicle smoothness, handling stability and other driving performance.

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

[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 can be easily overlapped and connected with the side window reinforcement plate 132 .

[0071] In some embodiments, Figure 3 , Figure 4 As shown, the side window assembly 13 includes: a side window inner plate 131; a side window reinforcement plate 132, which is arranged on the inner side of the side window inner plate 131 and is raised inwardly, the upper end of the side window reinforcement plate 132 is connected to the D-pillar assembly 11, and the lower end of the side window reinforcement plate 132 is connected to the wheel housing inner plate 121, and forms a first cavity 10. Therefore, the side window reinforcement plate 132 is not only used to enhance the structural strength of the upper body 1 at the side window, but also forms the first cavity 10 together with the side window inner plate 131, so that the upper part of the body 100 is connected with the lower part of the body 100, so that the vibration from the wheel is transmitted to the window through the connected cavity structure, and further part of the load received by the shock absorber 200 support is transmitted to the D ring, and the torsional rigidity of the body 100 is improved by dispersing the load through multiple paths.

[0072] In some embodiments, 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, and 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, and 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 overlapped with the support reinforcement plate 222 and then welded to each other.

[0073] In some embodiments, in the X direction (i.e., the longitudinal direction of the vehicle), the connection length dimension of the support body 221 and the rear longitudinal beam 211 is L1, the length dimension of the rear longitudinal beam 211 is L, and the relationship is satisfied: L1>1 / 2L. Thus, the support of the shock absorber 200 and the longitudinal beam are welded to form an integral structure, and the connection area under this size can make the installation hard point of the shock absorber 200 have very high rigidity in the three directions of X, Y, and Z, avoiding the abnormal noise and cracking problems caused by the poor rigidity of the shock absorber 200 support under harsh working conditions.

[0074] In some embodiments, 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 a 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. A part of the load received by the shock absorber support 200 is transmitted to various parts of the D ring. The load is dispersed through multiple paths, thereby improving the torsional stiffness of the vehicle body 100.

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

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

[0077] The vehicle according to the present invention has higher safety and improves the stability and sustainability of the vehicle by providing a corresponding vehicle body 100 .
