[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0045] Reference Figure 1-Figure 5 According to a first aspect of an embodiment of the present application, a vehicle body front compartment structure is provided.
[0046] The vehicle body front cabin structure comprises:
[0047] front crossbeam of ceiling 165;
[0048] A-pillars 162, two of the A-pillars 162 are spaced apart in the width direction of the vehicle;
[0049] Front wall crossbeam assembly 16;
[0050] The two ends of the ceiling front cross beam 165 are respectively connected to the two A-pillars 162, and the two ends of the front wall cross beam assembly 16 are respectively connected to the two A-pillars 162. The ceiling front cross beam 165, the two A-pillars 162 and the front wall cross beam assembly 16 form a first annular structure X, wherein the front wall cross beam assembly 16 is provided with a front wall transverse cavity 1676 extending in the vehicle width direction, such as Figure 2 shown.
[0051] Specifically, the first annular structure X composed of the two A-pillars 162, the front ceiling beam 165 and the dash panel beam assembly 16 can provide stable support for the front windshield and its surrounding area, meeting the installation strength and rigidity of the front windshield. The dash panel cross cavity 1676 provided in the dash panel beam assembly 16 can effectively improve the ability of the dash panel beam assembly 16 to resist deformation, and has a good absorption effect on the impact energy generated by the collision, especially the offset collision, which can improve the safety of the vehicle during actual driving. When the impact force is applied to the dash panel cross beam assembly 16 from the side, the dash panel cross cavity 1676 can provide sufficient buffering and absorption for the lateral energy, and the ceiling front cross beam 165 and the dash panel cross beam assembly 16 which are spaced apart in the front-to-back direction and in the up-down direction make the first annular structure X inclined, so that when subjected to the collision force from the front, it can effectively transmit the force in the annular structure and improve the structure of the interface between the front cabin and the passenger cabin, thereby reducing the intrusion of the front collision into the passenger cabin and the damage to the passenger cabin.
[0052] It can be understood that the front-to-back direction of the vehicle is the length direction of the vehicle, and the width direction of the vehicle is the left-to-right direction of the vehicle.
[0053] This technical solution utilizes the improved structure of the dash panel cross beam assembly 16 to improve the protection of the passenger compartment. In particular, the dash panel cross beam assembly 16 is provided with a cavity extending in the width direction, which can effectively strengthen the structural strength of the front compartment part, and can more effectively transmit the force to the two A-pillars 162; and the end of the A-pillar 162 is directly or indirectly connected to the dash panel cross beam assembly 16. The overall frame reliability of the A-pillar 162 and the dash panel cross beam assembly 16 is improved. The first annular structure X formed in the front area of the passenger compartment can effectively strengthen the structural reliability of the front of the passenger compartment.
[0054] Optionally, the vehicle body front compartment structure further includes a wheel house upper side beam 135, and the wheel house upper side beam 135 is respectively connected to the front wall cross beam assembly 16 and the A-pillar 162, such as Figure 1 and Figure 3 shown.
[0055] Specifically, the rear section of the wheel arch upper side beam 135 is connected to the middle section of the A-pillar 162, and the front section extends forward along the vehicle, and the wheel arch upper side beam 135 is also connected to the dash cross beam assembly 16, as a transition connection area, the dash cross beam assembly 16 and the A-pillar 162 are connected as a whole, providing a stable and firm connection relationship. The wheel arch upper side beam 135 itself has the function of protecting against side impact, and its structure can assist the first annular structure X to improve the reliability of the overall structure in front of the passenger compartment.
[0056] In a preferred embodiment of the present application, optionally, the dash panel cross beam assembly 16 further includes an upper cross beam 167 and a dash panel upper section 166. Figure 2 , Figure 4 and Figure 5 The upper cross beam 167 and the upper section 166 of the front wall are combined to form the front wall transverse cavity 1676 mentioned above.
[0057] Specifically, the dash panel cross beam assembly 16 is formed of an upper cross beam 167 and a dash panel upper section 166 to form a cavity structure, which is more lightweight while ensuring structural strength, and the manufacturing process is also simpler and easier, with low manufacturing costs. The dash panel transverse cavity 1676 formed by the upper cross beam 167 and the dash panel upper section 166 can play a role in buffering pressure. More specifically, the dash panel transverse cavity 1676 can effectively improve the ability of the dash panel cross beam assembly 16 to resist deformation, and has a good absorption effect on the impact energy generated by collision, especially offset collision, and can improve the safety of the vehicle during actual driving. When encountering impact deformation, the cavity 1676 between the upper cross beam 167 and the dash panel upper section 166 can provide space for deformation and absorption of the rear energy, reducing the risk of damage to the passenger compartment and the front windshield. At the same time, the formed cavity structure can also increase the cross-sectional area of the dash panel cross beam assembly 16, which can improve the force transmission effect.
[0058] In a preferred embodiment of the present application, optionally, there is a rear cover plate 137 above the wheel arch upper side beam 135, such as Figure 4 As shown,
[0059] The end of the upper cross beam 167 is directly fixedly connected to the wheel house upper side beam 135 , and the end of the upper section of the front panel 166 is fixedly connected to the upper side beam rear cover plate 137 of the wheel house upper side beam 135 .
[0060] Specifically, refer to Figure 3As shown, the upper side beam rear cover plate 137 is mainly used as a transition connection structure between the upper cross beam 167, the upper section of the front panel 166 and the wheel house upper side beam 135, firmly connecting the three together. The distance from the upper end of the wheel house upper side beam 135 in the Z direction can correspond to the height of the front panel cross beam assembly 16. By forming the upper side beam rear cover plate 137 on the upper side beam 135, it is helpful to increase the complexity of the connection structure here and form more cavities. For example Figure 4 As shown, the end of the upper cross beam 167 can be directly connected to the wheel house upper side beam 135, and the upper section of the front wall 166 is fixedly connected to the upper side beam rear cover 137, so that there is a difference between the cavities, the force transmission is more complicated, and it is more conducive to absorbing the impact energy. It also helps to transmit the force to the A-pillar 162 to achieve force dispersion.
[0061] In a preferred embodiment of the present application, the wheel house upper side beam 135 is optionally provided with a wheel house upper side beam cavity 1350 extending in the front-rear direction of the vehicle. Figure 4 The projection of the front panel transverse cavity 1676 in the vehicle width direction at least partially overlaps with the projection of the wheel house upper side beam cavity 1350 in the vehicle width direction.
[0062] Specifically, the wheel arch upper side beam cavity 1350 can strengthen the structural strength of the front side of the vehicle, and has a good impact absorption effect on the collision suffered by the vehicle during driving, especially the offset collision, and can effectively transfer the collision force from the front side to the rear of the vehicle. The projection of the wheel arch upper side beam cavity 1350 and the front panel transverse cavity 1676 at least partially overlap, which increases the absorption capacity for impact from the lateral and longitudinal directions. The overlap of the projections of the two cavities enables the force to be better transferred to other structures, and can better achieve mutual force transmission. During the actual operation of the vehicle, the vibration or impact force received by the upper side beam can be at least partially transmitted to the front panel transverse cavity 1676 through the upper side beam cavity 1350. The combination of the two further enhances the overall anti-seismic and anti-collision performance of the vehicle, and significantly improves the stability and safety of the vehicle during driving.
[0063] In a preferred embodiment of the present application, optionally, the vehicle body front compartment structure further includes:
[0064] A front windshield mounting side beam 161, two of the front windshield mounting side beams 161 are spaced apart in the width direction of the vehicle;
[0065] The front windshield has a crossbar of 163;
[0066] The two ends of the front cross beam 165 of the ceiling are respectively connected to the two front windshield mounting side beams 161, and the two ends of the front windshield lower cross beam 163 are respectively fixedly connected to the two front windshield mounting side beams 161. The front cross beam 165 of the ceiling, the two front windshield mounting side beams 161 and the front windshield lower cross beam 163 form a second annular structure Y. The first annular structure X and the second annular structure Y do not overlap, thereby further improving the structural strength of the front area of the passenger compartment and providing more reliable support for the installation of the windshield. On the premise of ensuring the reliability of the structure, the inclination angle of the glass can also have more options to provide users with a better observation field of view.
[0067] Specifically, refer to Figure 1 As shown, this preferred embodiment can improve the overall bearing capacity of the vehicle body structure for the downward force from the roof direction by combining the first annular structure X with the second annular structure Y. It also has a good bearing effect for the front impact force suffered in the event of an accidental collision; for the offset collision from the side, when the upper side beam is subjected to force, it can prevent the upper side beam from tilting inward due to the offset collision force, and can make the two colliding vehicles move away from each other at the collision point, thereby improving the safety of the vehicle during driving. When subjected to the collision force from the front, the two annular structures can effectively resist the force from the front, protect the passenger compartment from damage, or reduce the intrusion into the passenger compartment.
[0068] Optionally, in the front-rear direction of the vehicle, at least a portion of the front windshield mounting side beam 161 is located in front of the A-pillar 162. Figure 1 and 3 In the embodiment shown, most of the structure of the front windshield mounting side beam 161 is located in front of the A-pillar 162, which is used to support the front windshield glass. The A-pillar 162 located at the rear provides overall support for the front windshield mounting side beam 161 through the roof front cross beam 165 and the front wall cross beam assembly 16. On the other hand, a side windshield glass can also be arranged between the front windshield mounting side beam 161 and the A-pillar 165 to improve the user's field of vision.
[0069] refer to Figure 1 and Figure 3 As shown, the front windshield mounting side beam 161 at least partially located in front of the A-pillar 162 can protect the A-pillar 162 when the vehicle encounters a collision, preventing the A-pillar 162 from excessively bending into the passenger compartment and seriously endangering the lives of passengers, thereby improving the overall safety of the vehicle.
[0070] In a preferred embodiment of the present application, optionally, at least a portion of the front windshield lower cross beam 163 is a C-shaped structure, and the opening direction of the C-shaped structure is toward the passenger compartment of the vehicle, such as Figure 2As shown, the front end of the front windshield lower cross beam 163 is a C-shaped structure. The front windshield lower cross beam 163 with a C-shaped structure forms a windshield lower cross beam cavity 1630. This is a self-reinforcing structure. The front windshield lower cross beam 163 penetrates along the vehicle width direction to form a semi-open lower cross beam cavity 1630, which becomes the path bottom of the second annular structure Y. Further optionally, the front windshield lower cross beam 163 extends backward, such as Figure 2 As shown, it is connected to the cavity 1676 of the second annular structure X.
[0071] The bottom of the second annular structure X is the dash panel lower cross beam assembly. The dash panel upper section 166 and the dash panel upper cross beam 167 are buckled and connected to form the dash panel lower cross beam assembly. The two parts penetrate from left to right to form a through cavity 1676, which becomes the bottom of the first annular path X. The bottoms of the two annular paths both have cavities extending laterally and are connected to each other, effectively improving the protection performance of the front part of the passenger compartment.
[0072] The C-shaped structure of the front windshield lower cross beam 163 can effectively buffer and rebound the impact force when the vehicle encounters a head-on collision or an offset collision, thereby preventing the front cabin of the vehicle from excessive deformation and causing serious injuries to passengers, thereby improving the driving safety of the vehicle.
[0073] In a preferred implementation of the embodiment of the present application, optionally, an A-pillar cavity is formed in the A-pillar 162 , and an extension direction of the A-pillar cavity is along an extension direction of the A-pillar 162 ;
[0074] A side beam cavity is formed in the front windshield mounting side beam 161 , and an extension direction of the side beam cavity is along an extension direction of the front windshield mounting side beam 161 .
[0075] Specifically, the A-pillar cavity and the front windshield mounting side beam cavity both have good shock absorption effects, which can improve the pressure bearing capacity from the roof and fully absorb the impact force when it is hit. The front windshield mounting side beam 161 and the A-pillar 162 are particularly low, and the front windshield mounting side beam 161 and the A-pillar 162 are respectively used as the longitudinal structures of the annular structures X and Y. The cavities therein help to transfer the forces received by the lower structures such as the front panel cross beam assembly 16 and the wheel house upper side beam 135 upward to the roof front cross beam 165, thereby exerting the overall buffering effect of the annular structures X and Y and releasing the impact force. Compared with the case without a cavity, the force is more easily dispersed and absorbed. This design prevents serious injuries to passengers in the passenger compartment, thereby improving the operating stability and safety of the vehicle.
[0076] Cavity structures are provided in the front cross beam of the ceiling, the A-pillar, the front panel cross beam assembly 16, the front windshield mounting side beam, and the front windshield lower cross beam, so that the first ring structure and the second ring structure formed by connecting them are both ring structures formed by connecting multiple cavity structures to each other, which can not only enhance the strength of the ring structure, but also increase the force transmission cross-sectional area, thereby improving the force transmission effect and further protecting the passenger compartment.
[0077] In a preferred embodiment of the present application, optionally, a connecting plate 164 is also included. Figure 1 , Figure 3 and Figure 4 As shown, the connecting plate 164 is fixedly arranged above the wheel house upper side beam 135, the end of the front windshield lower cross beam 163 is connected to the connecting plate 164, and the front windshield lower cross beam 163 is fixedly connected to the front windshield mounting side beam 161 through the connecting plate 164. In the case where the wheel house upper side beam 135 has an upper side beam rear sealing plate 137, the connecting plate 164 is arranged above the upper side beam rear sealing plate 137.
[0078] The connecting plate 164 is used to improve the connection consistency between the A-pillar and the front windshield mounting side beam 161. Specifically, the connecting plate 164 plays a transitional connection role on the one hand, tightly connecting the front windshield lower cross beam 163 and the front windshield mounting side beam 161 together to ensure the connection strength. On the other hand, it can transmit the impact and vibration received to the front windshield lower cross beam 163, so that when the front windshield lower cross beam 163 is impacted, the front windshield mounting side beam 161 can also play a role in assisting in absorbing the impact force. The combination of the three improves the stability, comfort and safety of the vehicle as a whole during operation.
[0079] Alternatively, if Figure 3 As shown, the lower end of the front windshield mounting side beam 161 is connected to the connecting plate 164 , and the upper end of the front windshield mounting side beam 161 is connected to the A-pillar 162 . The lower end of the A-pillar 162 is connected to the connecting plate 164 .
[0080] The A-pillar 162, the connecting plate 164 and the front windshield mounting side beam 161 are combined to form a third annular structure, and the third annular structure is a triangular frame, such as Figure 3 shown.
[0081] Specifically, this design can effectively improve the structural reliability around the front windshield. Reduce the risk of damage and deformation of the front windshield. The triangular frame structure can improve the installation strength and rigidity of the front windshield. In addition, a side windshield can also be provided in the area formed by the connecting plate 164, the front windshield mounting side beam 161 and the A-pillar 162 to provide the user with an oblique front view. Moreover, this part of the structure is not easily damaged due to the support of the triangular frame. The technical solution can indirectly adjust the size of the α angle by adjusting the front and rear positions of the front windshield lower cross beam 163 and the front panel cross beam assembly 16, thereby adjusting the appearance of the vehicle model and the user's field of vision, and the overall structural strength will not have obvious defects due to this adjustment.
[0082] In some embodiments of the present disclosure, the third annular structure can effectively strengthen the structural strength of the first annular structure and the second annular structure at this position, so that they can transmit force more effectively, and the annular structure can provide sufficient collapse distance to further reduce damage to the passenger compartment.
[0083] In a preferred embodiment of the present application, optionally, the A-pillar 162 includes a first connection portion 1621 and a second connection portion 1622, the front windshield mounting side beam 161 is connected to the first connection portion 1621, and the connection plate 164 is connected to the second connection portion 1622. Figure 3 As shown, the upper end of the A-pillar is a first connection portion 1621, which is integrally connected to the front cross beam 165 of the roof and the front windshield mounting side beam 161. The lower end of the A-pillar is a second connection portion 1622, which is used to be fixedly connected to the connecting plate 164 and the structure below to improve the reliability of the basic connection.
[0084] In particular, such as Figure 3 and Figure 5 As shown, the A-pillar 162 may have an A-pillar lower section 171 , and the A-pillar lower section 171 is directly fixedly connected to the wheel house upper side beam 135 .
[0085] Specifically, the lower section of the A-pillar is the first connecting portion 1621 or the part of the A-pillar structure located below the connecting plate; the lower section of the A-pillar 171 is fixedly connected to the upper side beam of the wheel house 135, that is, the A-pillar 162 is fixedly connected to the upper side beam of the wheel house 135 and the front panel cross beam assembly 16 at the same time. With such a design, the A-pillar 162 can effectively play a supporting role between the roof and the upper side beam of the wheel house. When the A-pillar is subjected to the impact pressure from the upper side beam of the wheel house, the force can be effectively transmitted to the vehicle roof and the front panel cross beam assembly 16. Combined with the shock-absorbing effect of the front panel transverse cavity and the upper side beam cavity, the pressure and impact force on the front cabin structure of the vehicle body can be effectively resolved. The overall vertical through design of the A-pillar 162 and the lower section of the A-pillar 171 significantly strengthens the integrity of the front cabin structure of the vehicle body. It prevents the A-pillar 162 from excessively deforming or even breaking into the passenger compartment when encountering an emergency during the driving of the vehicle, thereby causing serious harm to the passengers in the passenger compartment.
