[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0029] In the related art, due to the influence of the low vehicle height and the requirements of the front upper vision regulations, the cavity formed between the inner panel of the front crossbeam and the outer panel of the front crossbeam in the vehicle height direction is small. The inner panel of the front crossbeam in the traditional structure is a U-shaped groove structure, and the strength and stiffness of the front crossbeam structure are relatively weak, and the anti-load-bearing capacity is poor, which seriously affects the safety and stability of the vehicle during operation.

[0030] The following refers to Figures 1-3 describe a front crossbeam structure for a vehicle according to an embodiment of the present invention.

[0031] The front crossbeam structure for a vehicle according to the present utility model includes: an inner front crossbeam 12 and an outer front crossbeam 11. A plurality of first reinforcing protrusions 121 protruding towards the passenger compartment are formed on the inner front crossbeam 12, and a second reinforcing protrusion 122 protruding away from the passenger compartment is formed between two adjacent first reinforcing protrusions 121; the outer front crossbeam 11 is disposed on the side of the inner front crossbeam facing away from the passenger compartment inside the front crossbeam, and the outer front crossbeam 11 is at least partially spaced apart from the first reinforcing protrusion 121 to form a cavity.

[0032] In some specific embodiments, the front crossbeam is disposed in the front region of the vehicle top structure. The front crossbeam can support the vehicle top structure. The front crossbeam is composed of the inner front crossbeam 12 and the outer front crossbeam 11. A plurality of first reinforcing protrusions 121 are formed on the inner front crossbeam 12 at intervals. The first reinforcing protrusions 121 protrude towards the passenger compartment. A second reinforcing protrusion 122 is formed between two adjacent first reinforcing protrusions 121. The second reinforcing protrusion 122 protrudes away from the passenger compartment, increasing the moment of inertia of the cross-sectional area of the front crossbeam structure. Thus, when the front crossbeam structure is subjected to loads in the vertical or horizontal directions, it can provide stronger bending and torsional stiffness. At the same time, due to the vehicle design requirements of a lower vehicle height and a good forward upper field of view, the design of the first reinforcing protrusions 121 and the second reinforcing protrusions 122 can increase the lateral and longitudinal supports of the inner front crossbeam 12 while maintaining a lower height, meeting the regulatory requirements and enhancing the strength and stiffness of the vehicle body. The outer front crossbeam 11 is disposed on the side of the inner front crossbeam 12 facing away from the passenger compartment, and the outer front crossbeam 11 is at least partially spaced apart from the plurality of first reinforcing protrusions 121 to form a continuous irregular cavity. The continuous irregular cavity structure can provide additional support and reinforcement compared to a flat single-layer cavity structure, increasing the moment of inertia of the cross-sectional area of the front crossbeam structure, thereby enhancing the mode of the local area of the front crossbeam structure.

[0033] The front crossbeam structure according to the present utility model increases the lateral and longitudinal supports of the inner front crossbeam 12 by forming a plurality of first reinforcing protrusions 121 protruding towards the passenger compartment on the inner front crossbeam 12, enhancing the strength and stiffness of the vehicle body. A second reinforcing protrusion 122 protruding away from the passenger compartment is formed between two adjacent first reinforcing protrusions 121. The outer front crossbeam 11 is disposed on the side of the inner front crossbeam 12 facing away from the passenger compartment, and the outer front crossbeam 11 is at least partially spaced apart from the plurality of first reinforcing protrusions 121 to form a continuous irregular cavity. The continuous irregular cavity structure can provide additional support and reinforcement, increasing the moment of inertia of the cross-sectional area of the front crossbeam structure, thereby enhancing the mode of the local area of the front crossbeam structure.

[0034] According to some embodiments of the present utility model, a third reinforcing convex portion 123 protruding toward the front crossmember inner panel 12 is formed on the front crossmember outer panel 11, and the third reinforcing convex portion 123 is adapted to be connected to the second reinforcing convex portion 122.

[0035] In some specific embodiments, a third reinforcing convex portion 123 is formed on the front crossmember outer panel 11. The third reinforcing portion protrudes toward the crossmember inner panel. At least a part of the third reinforcing convex portion 123 is in contact with the second reinforcing convex portion 122 to realize the welding of the front crossmember outer panel 11 and the front crossmember inner panel surface. The front crossmember inner panel 12 and the front crossmember outer panel 11 can be combined into an integral body for welding with the vehicle body frame, achieving the goal of simultaneously installing the front crossmember outer panel 11 and the front crossmember inner panel while ensuring the body stiffness, simplifying the assembly process and steps of the front crossmember structure, shortening the assembly time of each vehicle, and thus improving the vehicle production efficiency and production economy.

[0036] According to some embodiments of the present utility model, the first reinforcing convex portion 121 and the second reinforcing convex portion 122 are parallel to each other and extend in the width direction of the front crossmember inner panel 12. During a vehicle collision, energy can be transmitted and absorbed along the extending directions of the first reinforcing convex portion 121 and the second reinforcing convex portion 122, rather than directly transmitted to the occupant compartment, reducing the direct impact on the occupants in the occupant compartment and improving the safety of the vehicle during operation. At the same time, the first reinforcing convex portion 121 and the second reinforcing convex portion 122 extending in the width direction of the front crossmember inner panel 12 can increase the lateral and longitudinal supports of the front crossmember inner panel 12 while maintaining a relatively low height, meeting the requirements of the vision regulations and enhancing the strength and stiffness of the vehicle body.

[0037] According to some embodiments of the present utility model, the first reinforcing convex portion 121 is configured such that its cross-sectional area gradually decreases in the direction toward the occupant compartment. When the vehicle undergoes a frontal collision, starting from the contact point, as the cross-sectional area of the first reinforcing convex portion 121 gradually decreases, the strain degree of the material can be gradually increased, thereby more efficiently absorbing and consuming the collision energy. At the same time, the progressive deformation design of the first reinforcing convex portion 121 helps to guide the collision energy to be transmitted along the expected path, avoiding energy concentration at a certain point causing local severe damage, and thus improving the stability and safety of the vehicle during operation.

[0038] According to some embodiments of the present utility model, the front crossmember structure further includes: a connecting plate 13. The connecting plate 13 is formed with a first connection area and a second connection area arranged at intervals. The first connection area is adapted to face and connect to the vehicle body, and the second connection area is adapted to face and connect to at least a part of the front crossmember inner panel 12.

[0039] In some specific embodiments, a connecting plate 13 is further disposed inside the front crossbeam structure. The connecting plate 13 is formed with a first connection area and a second connection area in the vehicle width direction. The first connection area and the second connection area are spaced apart from each other. The first connection area can be connected to the body main frame, and one side of the second connection area in the thickness direction is disposed opposite to and at least partially connected to the inner panel 12 of the front crossbeam. Thus, the inner panel 12 of the front crossbeam is tightly connected to the body main frame through the connecting plate 13, improving the structural strength and rigidity of the front end of the vehicle top, and enhancing the driving stability and handling performance of the vehicle under complex road conditions.

[0040] According to some embodiments of the present invention, the connecting plate 13 is disposed on the side of the inner panel 12 of the front crossbeam facing the passenger compartment. The connecting plate 13 is formed with a first positioning portion 111, and the outer panel 11 of the front crossbeam is formed with a second positioning portion 112 that is positioned and matched with the first positioning portion 111. The first positioning portion 111 and the second positioning portion 112 are adapted to limit the position of the connecting plate 13 relative to the outer panel 11 of the front crossbeam, effectively preventing the front crossbeam structure from shaking during welding with the connecting plate 13, ensuring that the connecting plate 13 can be accurately aligned with the outer panel 11 of the front crossbeam during installation, thereby avoiding structural deviations caused by installation errors between the connecting plate 13 and the front crossbeam structure, improving the overall assembly accuracy and reliability of the front crossbeam structure. At the same time, the cooperation of the first positioning portion 111 and the second positioning portion 112 enables the assembly worker to quickly and intuitively identify the correct installation position of the connecting plate 13 and the front crossbeam structure, without complex measurement and calibration steps, thus simplifying the assembly process, shortening the assembly time, and improving the production efficiency of the vehicle.

[0041] According to some embodiments of the present invention, one of the first positioning portion 111 and the second positioning portion 112 is configured as a positioning post, and the other of the first positioning portion 111 and the second positioning portion 112 is configured as a positioning hole.

[0042] In some specific embodiments, the first positioning portion 111 can be configured as a positioning post, and the second positioning portion 112 can be configured as a positioning hole. The inner panel 12 of the front crossbeam is formed with a through hole that is disposed opposite to the positioning hole. On the one hand, the positioning post passes through the through hole and cooperates with the positioning hole to limit the outer panel of the crossbeam, effectively preventing the front crossbeam and the connecting plate 13 from shaking during the assembly process. At the same time, the precise matching of the positioning post and the positioning hole ensures the accurate positioning between the connecting plate 13, the outer panel 11 of the front crossbeam, and the vehicle body, avoiding misalignment or offset between the front crossbeam structure and the connecting plate 13 during the assembly process, improving the assembly accuracy of the front crossbeam structure and the connecting plate 13 and the overall assembly quality. On the other hand, through the simple and rapid connection mechanism of the positioning post and the positioning hole, the assembly worker can complete the pre-connection of the front crossbeam structure and the connecting plate 13 in a short time, without complex alignment and fixing operations, greatly simplifying the assembly process and improving the production efficiency of the vehicle.

[0043] According to some embodiments of the present utility model, the outer panel 11 of the front cross member is formed with liquid leakage holes 101 penetrating in the thickness direction on the third reinforcing convex portion 123.

[0044] In some specific embodiments, the outer panel 11 of the front cross member is formed with liquid leakage holes 101 on the third reinforcing convex portion 123. The liquid leakage holes 101 penetrate through the third reinforcing convex portion 123 in the thickness direction. During the daily driving of the vehicle, liquids such as rainwater, road surface water or coolant may accumulate in the front cross member structure area. The setting of the liquid leakage holes 101 can ensure that these liquids can be discharged from the front cross member structure area in time, avoid the accumulation of liquids inside the front cross member structure, reduce the corrosion risk of the front cross member structure, extend the service life of the front cross member structure, and at the same time help to keep the vehicle clean and dry. At the same time, without affecting the structural strength of the outer panel 11 of the front cross member, the liquid leakage holes 101 can also reduce the weight of the outer panel 11 of the front cross member to some extent, which is helpful for the lightweight design of the whole vehicle.

[0045] According to some embodiments of the present utility model, the outer panel 11 of the front cross member is formed with oblong holes 102 located on the outer periphery of the third reinforcing convex portion 123, so that the inner panel of the strong cross member leaks out from the oblong holes 102. The oblong holes 102 are opposite to the connecting plate 13, and the welding gun can directly weld the inner panel of the strong cross member and the connecting plate 13 without indirect welding through the outer panel. The direct welding of the inner panel 12 of the front cross member and the connecting plate 13 can ensure the connection strength and stiffness between the inner panel 12 of the front cross member and the connecting plate 13, improve the stability of the connection between the front cross member structure and the connecting plate 13. At the same time, the design of the oblong holes 102 may reduce the material use of the outer panel 11 of the front cross member in some cases, which is helpful for the lightweight design of the vehicle body and can also save manufacturing costs.
