[0045] The embodiments of the present application are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application are described in detail below.

[0046] The embodiments of the present application are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application are described in detail below. Figures 1-5 The front wheel cover longitudinal beam assembly 100 according to an embodiment of the present application is described below, and the present application also proposes a vehicle body structure.

[0047] Referring to Figures 1-5 The front wheel cover longitudinal beam assembly 100 according to an embodiment of the present application is described below, and the present application also proposes a vehicle body structure.

[0048] The longitudinal beam body 10 is a bulging pipe structure. Pipe bulging is a forming process that relies on material stretching to expand the pipe blank in the radial direction under the action of pressure. According to the requirements of the workpiece, the pipe blank can be expanded locally or the entire pipe blank can be expanded.

[0049] And, since the expanded tube structure has high strength, small overall size, and few connection nodes when connected with other structures, the driver / passenger space is optimized.

[0050] Thus, by using the integrally formed longitudinal beam body 10, the number of parts and connection points can be reduced, thereby optimizing the driver / passenger space, and the precision of the front wheelhouse longitudinal beam assembly 100 can be improved due to the small number of connection points.

[0051] The longitudinal beam body 10 includes a first section 11 and a second section, the first section 11 and the second section are connected to each other, the first section 11 is adapted to be connected to the front longitudinal beam assembly 200, and the second section is adapted to be connected to the wheelhouse body 300. In this way, the strength and stability of force transmission during the collision process are ensured while meeting the requirements of styling and chassis layout space.

[0052] The first section 11 and the second section are integrally formed, i.e., the longitudinal beam body 10 is an expanded tube structure. Tube expansion is a forming process that relies on material stretching to expand the diameter of a small-diameter tube blank outward in the radial direction under pressure. According to the requirements of the workpiece, the tube blank can be partially expanded or the entire tube blank can be expanded.

[0053] Further, the second section includes a first sub-section 12 and a second sub-section 13, the first sub-section 12 and the second sub-section 13 are connected to each other and are integrally formed, the first sub-section 12 is adapted to be connected to one end of the wheelhouse body 300, and the second sub-section 13 is adapted to be connected to the other end of the wheelhouse body 300. That is, the second section is composed of the first sub-section 12 and the second sub-section 13 connected to each other, and the first sub-section 12 is connected to one end of the wheelhouse body 300, and the second sub-section 13 is connected to the other end of the wheelhouse body 300.

[0054] The other end of the wheelhouse body 300 is the junction between the wheelhouse body 300 and the front section of the A-pillar 400.

[0055] Referring to Figure 1 and Figure 2 The front wheelhouse longitudinal beam assembly 100 further includes a sleeve assembly that is arranged through the longitudinal beam body 10 to be adapted to connect the longitudinal beam body 10 and the front longitudinal beam assembly 200, and to be adapted to connect the longitudinal beam body 10 and the wheelhouse body 300. The sleeve assembly can absorb the connection tolerance between the longitudinal beam body 10 and the front longitudinal beam assembly 200, and the sleeve assembly can absorb the connection tolerance between the longitudinal beam body 10 and the wheelhouse body 300.

[0056] As Figure 3As shown, the sleeve assembly comprises: a first sleeve 31, the first sleeve 31 is provided in the first section 11. Wherein, the front section of the longitudinal beam body 10 is vertical, one-way connection, the connection surface process precision is controllable, the collision energy is larger, by setting the first sleeve 31 to connect the first section 11 and the front longitudinal beam assembly 200, it can not only guarantee the connection precision and reliability, but also reserve the situation that the connection strength is insufficient in the collision process, facilitate to add structural glue connection, improve the connection strength and the collision stability.

[0057] Wherein, the first section 11 is provided with a first through hole, the first sleeve 31 is matched in the first through hole, and the first sleeve 31 and a part of the longitudinal beam body 10 are fixedly connected. That is to say, the first through hole is opened on the first section 11, and the inner diameter of the first through hole is larger than the outer diameter of the first sleeve 31, so that the first sleeve 31 can be matched in the first through hole.

[0058] Further, the first sleeve 31 and a part of the longitudinal beam body 10 are fixedly connected by welding. That is, the first section 11 and the first sleeve 31 are fixed by using burn welding connection in the front station process, forming an integral.

[0059] In addition, the front wheel cover longitudinal beam assembly 100 further comprises: a first fastener, the first fastener is provided in the first sleeve 31 and is suitable for fixedly connecting with the front longitudinal beam assembly 200. That is to say, the first through hole is provided in the first sleeve 31, wherein the first fastener can pass through the first sleeve 31 and be fixedly connected with the front longitudinal beam assembly 200, that is, the fixed connection between the first section 11 and the front longitudinal beam assembly 200 is realized by the first fastener and the first sleeve 31.

[0060] Wherein, one end of the first fastener abuts against the first sleeve 31, and the other end of the first fastener is fixedly connected with the front longitudinal beam assembly 200, so that the connection tolerance between the first fastener and the front longitudinal beam assembly 200 can be absorbed by the first sleeve 31.

[0061] Specifically, the first fastener is a bolt, the bolt is fixedly connected with a nut after passing through the first sleeve 31 and the front longitudinal beam assembly 200, so as to realize the fixed effect of the first fastener.

[0062] The first sleeve 31 and the first fastener are both multiple, and the multiple first sleeves 31 are arranged at intervals in the part of the longitudinal beam body 10 in the extension direction. In this way, the first section 11 and the front longitudinal beam assembly 200 are fixedly connected by the multiple first fasteners, so as to improve the connection strength between the first section 11 and the front longitudinal beam assembly 200. In addition, the outer side of each first fastener is sleeved with the first sleeve 31, so as to further absorb the connection tolerance between the first section 11 and the front longitudinal beam assembly 200.

[0063] The first section 11 extends in the vertical direction, that is, the plurality of first sleeves 31 are arranged at intervals in the vertical direction of the first section 11.

[0064] Further, one end of the first sleeve 31 penetrates a part of the longitudinal beam body 10 away from one side of the front longitudinal beam assembly 200, and the other end of the first sleeve 31 abuts against a part of the longitudinal beam body 10 close to one side of the front longitudinal beam assembly 200. That is, the first sleeve 31 is a half-through type, that is, one end of the first sleeve 31 penetrates the first section 11, and the other end of the first sleeve 31 abuts directly against the first section 11. This is because the first section 11 is a vertical structure, so that the overall precision of the first section 11 is relatively high, so that the first sleeve 31 does not need to completely penetrate the first section 11, which can achieve the effect of reducing cost.

[0065] In this way, through the cooperation of the first sleeve 31 and the first section 11, the connection precision and reliability of the first section 11 and the front longitudinal beam assembly 200 can be ensured, and in the case that the connection strength is insufficient during the collision process, the structure glue connection can be easily added to improve the connection strength and the collision stability.

[0066] Referring to Figure 3 The sleeve assembly includes a second sleeve 32, and the second section includes a first sub-section 12 and a second sub-section 13, the first sub-section 12 is arranged between the first section 11 and the second sub-section 13, and the second sleeve 32 penetrates the first sub-section 12. The middle section of the longitudinal beam body 10 is an arch-shaped three-dimensional multi-surface structure. In order to connect the vertical section at the front end of the longitudinal beam body 10 and the horizontal section at the rear end, and to ensure the overall stiffness and strength of the wheel cover body 300, another part of the longitudinal beam body 10 needs to be connected with the wheel cover body 300. However, the precision deviation of the expanded tube after forming is not easy to control in the arch-shaped three-dimensional multi-surface structure, and if the longitudinal beam body 10 is directly connected with the wheel cover body 300, there is a risk of poor connection and poor precision, which also leads to the risk of instability of the collision force transmission. Therefore, the middle section of the longitudinal beam body 10 is connected with the second sleeve 32 through a hole, and the position precision of the second sleeve 32 is adjusted to ensure the overall connection point precision and the overall precision and the stability of the collision force transmission. The above-mentioned connection structure is optimized to three Y-direction two sections at this position, which can meet the performance requirements of the crashworthiness.

[0067] The first sub-section 12 is provided with a second through hole, and the second sleeve 32 is fitted in the second through hole. That is, the second through hole is formed in the first sub-section 12, and the inner diameter of the second through hole is greater than the outer diameter of the second sleeve 32, so that the second sleeve 32 can be fitted in the second through hole.

[0068] Further, the second sleeve 32 and the other part of the longitudinal beam body 10 are fixedly connected by welding. That is, the first sub-section 12 and the second sleeve 32 are fixedly connected by welding at the front work station, forming an integral whole.

[0069] The front wheel cover longitudinal beam assembly 100 further comprises a second fastener, which is arranged through the second sleeve 32 and is adapted to be fixedly connected with the middle section of the wheel cover body 300. That is, a through hole is arranged in the second sleeve 32, and the second fastener can be fixedly connected with the wheel cover body 300 after being arranged through the second sleeve 32, that is, the first sub-section 12 and the middle section of the wheel cover body 300 are fixedly connected by the second fastener and the second sleeve 32.

[0070] Specifically, the second fastener is a bolt, which is directly fixedly connected with the wheel cover body 300 after being arranged through the second sleeve 32.

[0071] The second sleeve 32 and the second fastener are both provided in plurality, and the plurality of second sleeves 32 are arranged at intervals in the extension direction of the other part of the longitudinal beam body 10. In this way, the first sub-section 12 and the wheel cover body 300 are fixedly connected by the plurality of second fasteners, so that the connection strength between the first sub-section 12 and the wheel cover body 300 can be improved. In addition, the outer side of each second fastener is sleeved with the second sleeve 32, so that the connection tolerance between the first sub-section 12 and the wheel cover body 300 can be further absorbed.

[0072] Here, the first sub-section 12 extends in the vertical direction, that is, the plurality of second sleeves 32 are arranged at intervals in the vertical direction of the first sub-section 12.

[0073] In addition, the second sleeve 32 abuts against the wheel cover body 300 after penetrating the other part of the longitudinal beam body 10. This is because the first sub-section 12 has an arc-shaped structure, so that the precision of the first sub-section 12 is relatively poor. The tolerance generated during the processing of the first sub-section 12 is absorbed by the penetrating second sleeve 32, so that the precision of the front wheel cover longitudinal beam assembly 100 can be improved.

[0074] In this way, the first sub-section 12 is fixedly connected with the second sleeve 32 by digging a hole, and the overall connection point precision is ensured by adjusting the position precision of the second sleeve 32, so that the overall precision and the stability of the collision force transmission can be ensured. Here, the above-mentioned connection structure is optimized to three Y-direction two sections at this position connection point, which can meet the requirements of the crash performance.

[0075] Referring to Figure 1 and Figure 2As shown, the front wheel house longitudinal beam assembly 100 further comprises: an upper cover plate 20, the upper cover plate 20 is arranged on the second section and is fixedly connected with the wheel house body 300. In the collision process, since the second section is an excessive section connecting the front end of the front longitudinal beam and the front end of the A column 400, an arch-shaped excessive section is necessarily required to connect the front and rear sections. In the collision process, this arch-shaped area is prone to instability or fracture risk, resulting in force transmission failure. In order to reduce this risk, the upper cover plate 20 is arranged on the second section, which improves the overall rigidity of the wheel house body 300. This is not only beneficial to the force transmission path in the front-rear direction during the collision process, but also beneficial to the vehicle posture side slip during the small offset collision, thereby realizing the energy conversion of the collision generated energy into the vehicle body side slip, reducing the passenger compartment intrusion and injury value, and improving the crashworthiness.

[0076] Further, the upper cover plate 20 is arranged on the first sub-section 12.

[0077] As shown in the drawings, Figure 4 The upper cover plate 20 comprises: a main body 21 and two flanges 22 arranged on both sides of the main body 21, and a containing space of the second section is defined between the main body 21 and the wheel house body 300, and the two flanges 22 are adapted to be fixedly connected with the wheel house body 300. That is, the upper cover plate 20 is composed of the main body 21 and the flanges 22 arranged on both sides of the main body 21. In this way, the main body 21 can be arranged on the outside of the first sub-section 12, and the flanges 22 can be fixedly connected with the wheel house body 300, so as to realize the fixation of the upper cover plate 20 on the outside of the first sub-section 12. In this way, the overall rigidity at the wheel house body 300 can be improved, which is beneficial to the force transmission path in the front-rear direction during the collision process, and reduces the passenger compartment intrusion and injury value during the small offset collision, thereby improving the crashworthiness.

[0078] In addition, as shown in the drawings, Figure 4 The flange 22 is provided with at least one first mounting hole 24, and the first mounting hole 24 is adapted to be fixedly connected with the wheel house body 300.

[0079] As shown in the drawings, Figure 4 The upper cover plate 20 is provided with a avoiding groove 23 avoiding the second sleeve 32. That is, by arranging the avoiding groove 23 on the upper cover plate 20, the second sleeve 32 can be avoided, so that the upper cover plate 20 does not affect the arrangement of the second sleeve 32.

[0080] Of course, the upper cover plate 20 is provided with avoiding grooves 23 on both sides, so that both ends of the second sleeve 32 can be avoided.

[0081] Further, the upper cover plate 20 is provided with a plurality of avoiding grooves 23 in the extension direction of the first sub-section 12, that is, the plurality of avoiding grooves 23 can correspond to the plurality of second sleeves 32.

[0082] Further, the front wheelhouse longitudinal beam assembly 100 further comprises: a third fastener, the second section comprises: a first sub-section 12 and a second sub-section 13, the first sub-section 12 is arranged between the first section 11 and the second sub-section 13, the second sub-section 13 is provided with a second mounting hole, and the third fastener is fixedly connected with the rear section of the wheelhouse body 300 and the front end of the A-pillar after penetrating through the second mounting hole. That is, since the second sub-section 13 tends to be a horizontal direction cavity structure, the connection surface process precision is controllable, the collision energy tends to be weakened, and further deformation is required to absorb the energy in the collision process, so the third fastener is used to realize the direct connection structure design of the second sub-section 13 and the wheelhouse body 300. At the same time, in order to ensure better connection stability, structural glue is added to the connection surface to improve the connection strength and the collision stability.

[0083] Specifically, the second sub-section 13 is provided with a second mounting hole, and the wheelhouse body 300 is provided with a third mounting hole, so that the third fastener is fixedly connected with the third mounting hole after penetrating through the second mounting hole, thereby realizing the fixed connection between the second sub-section 13 and the wheelhouse body 300.

[0084] Further, the third fastener is a plurality of third fasteners, and the plurality of third fasteners are arranged on at least one side surface of the second sub-section 13, and / or the plurality of third fasteners are arranged at intervals in the extension direction of the second sub-section 13. In this way, the second sub-section 13 and the wheelhouse body 300 are fixedly connected by the plurality of third fasteners, so as to improve the connection strength between the second sub-section 13 and the wheelhouse body 300.

[0085] The plurality of third fasteners can be arranged at intervals in the extension direction of the second sub-section 13, and of course, the plurality of third fasteners can also be arranged on the plurality of side surfaces of the second sub-section 13.

[0086] In addition, referring to Figure 1 and Figure 2 , the front wheelhouse longitudinal beam assembly 100 further comprises: a connecting plate 40, the connecting plate 40 is fixed on the second sub-section 13, and the connecting plate 40 is adapted to be connected with a functional accessory. That is, the connecting plate 40 is further arranged on the second sub-section 13, and one end of the connecting plate 40 away from the second sub-section 13 is connected with the functional accessory, so that the functional accessory can be fixed on the second sub-section 13 through the connecting plate 40. The functional accessory can be various supports.

[0087] Specifically, the connecting plate 40 and the second sub-section 13 are fixedly connected by welding.

[0088] Further, the connecting plate 40 and the functional accessory are fixedly connected by bolts or screws.
