Description

Technical Field

[0001] This utility model relates to the field of vehicle body structure technology, and in particular to a front compartment structure of a vehicle body and an automobile. Background Technology

[0002] Currently, a front compartment reinforcing beam is installed between the front upper crossbeam and the upper side beam of the front compartment structure to enhance the structural strength of the front compartment and ensure the torsional stiffness, torsional mode, and yaw mode of the body-in-white.

[0003] like Figure 1 , Figure 2 As shown, the existing front compartment structure includes a front upper crossbeam 1a, a front upper crossbeam column 2a, and a front compartment upper side beam 3a. The front compartment reinforcing beam 4a is manufactured using a stamping process and connected to the front upper crossbeam 1a, front upper crossbeam column 2a, and front compartment upper side beam 3a via bolts or welding. However, to ensure compliance with requirements for torsional stiffness, torsional mode, and front compartment yaw mode, the size of the front compartment reinforcing beam needs to be increased, occupying considerable space in the front compartment. Furthermore, due to space constraints, the stamped front compartment reinforcing beam 4a can only be a single-layer sheet metal structure, unable to form a closed cavity, thus limiting its effectiveness in enhancing the performance of the body-in-white.

[0004] In summary, the existing front compartment reinforcement beams of the vehicle body are large in size and occupy a lot of front compartment space. Moreover, the single-layer sheet metal structure of the front compartment reinforcement beams cannot form a closed cavity, making it difficult to improve the structural performance of the body-in-white.

[0010] Furthermore, the second connector is an integral groove structure, with one end of the groove engaging with the other end of the front cabin reinforcing beam, and the other end of the groove engaging with the upper side beam of the front cabin.

[0011] Furthermore, the slot of the second connector faces inward, one end of the second connector extends parallel to the length direction of the front cabin reinforcing beam, and the other end of the second connector is bent relative to the length direction of the front cabin reinforcing beam.

[0014] Furthermore, the front cabin reinforcing beam is also provided with a first support and a second support. The first support is used to fix the hood buffer plug, and the second support is used to fix the hood support rod buckle.

The front upper crossbeam is fixedly connected to the front upper crossbeam column, and the front compartment upper side beam and the front upper crossbeam are arranged at intervals.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] like Figures 3 to 6As shown, a front compartment structure of the vehicle body according to an embodiment of the present invention includes a front upper crossbeam 1, a front upper crossbeam column 2, a front compartment upper side beam 3, and a front compartment reinforcing beam 4. The front upper crossbeam 1 is fixedly connected to the front upper crossbeam column 2, and the front compartment upper side beam 3 is arranged at intervals with the front upper crossbeam 1. The front compartment reinforcing beam 4 is obliquely connected between the front upper crossbeam 1 and the front compartment upper side beam 3. The front compartment reinforcing beam 4 is a hollow tube. A first connector 41 is fixedly installed at one end of the front compartment reinforcing beam 4, and a second connector 42 is fixedly installed at the other end of the front compartment reinforcing beam 4. Both the first connector 41 and the second connector 42 are sheet metal parts. The first connector 41 is overlapped and fixed at the intersection of the front upper crossbeam 1 and the front upper crossbeam 2, and the second connector 42 is overlapped and fixed at the end of the front compartment upper side beam 3.

[0032] The front compartment structure of this vehicle adopts a design consisting of a front upper crossbeam 1, a front upper crossbeam pillar 2, a front compartment upper side beam 3, and a front compartment reinforcing beam 4. The front compartment upper side beam 3 is spaced apart from the front upper crossbeam 1, and the front compartment reinforcing beam 4 is diagonally connected between the front upper crossbeam 1 and the front compartment upper side beam 3. The front compartment reinforcing beam 4, together with the front upper crossbeam 1 and the front compartment upper side beam 3, forms a triangular force transmission structure, which can significantly improve the torsional stiffness and bending stiffness of the front compartment. Among them, the front compartment reinforcing beam 4 is a hollow tube with a closed force transmission cavity, which not only effectively reduces the size of the front compartment reinforcing beam 4, but also provides greater load-bearing capacity and buckling resistance.

[0033] A first connector 41 is fixedly installed at one end of the front compartment reinforcing beam 4, and a second connector 42 is fixedly installed at the other end of the front compartment reinforcing beam 4. Both the first connector 41 and the second connector 42 are sheet metal parts. The first connector 41 can form a reliable overlapping and fixing relationship with the intersection of the front compartment reinforcing beam 4, the front upper crossbeam 1, and the front upper crossbeam 1. The second connector 42 can form a reliable overlapping and fixing relationship with the front compartment reinforcing beam 4 and the front compartment upper side beam 3. The overlapping method of the sheet metal parts increases the contact area, resulting in high connection strength and good surface adaptability. The front compartment reinforcing beam 4 of this body structure can avoid occupying a large amount of front compartment space, and the front compartment reinforcing beam 4 can form a closed cavity, thereby improving the torsional stiffness, torsional mode, and front compartment yaw mode of the body-in-white.

[0034] In this embodiment, the front compartment reinforcing beam 4 is a square tube beam. The square tube beam per unit cross-sectional area can provide greater structural stiffness, ensuring the torsional stiffness, torsional mode, and front compartment yaw mode performance of the body-in-white. Specifically, the first connector 41 is an integral groove structure. The width of the groove at one end of the first connector 41 is smaller than the width of the groove at the other end of the first connector 41.

[0035] The first connector 41 adopts an integrated groove structure with a narrow groove at one end and a wide groove at the other end. This improves the surface matching between the first connector 41 and the front cabin reinforcing beam 4 and the front upper crossbeam 1, ensuring the connection strength at this location. As a further preferred embodiment, the groove of the first connector 41 is positioned downwards, with one end of the first connector 41 extending parallel to the length direction of the front cabin reinforcing beam 4, and the other end of the first connector 41 bent relative to the length direction of the front cabin reinforcing beam 4, satisfying the installation angle of this structure.

[0036] In this embodiment, the second connector 42 is an integral groove structure. One end of the groove of the second connector 42 is in a concave-convex fit with the other end of the front cabin reinforcing beam 4, and the other end of the groove of the second connector 42 is in a concave-convex fit with the upper beam 3 of the front cabin. The first connector 41 adopts an integral groove structure, which improves the surface matching degree between the second connector 42 and the front cabin reinforcing beam 4 and the upper beam 3 of the front cabin, and ensures the connection strength at this point.

[0037] The slot of the second connector 42 faces inward. One end of the second connector 42 extends parallel to the length direction of the forward cabin reinforcing beam 4, while the other end of the second connector 42 is bent relative to the length direction of the forward cabin reinforcing beam 4. Furthermore, the edge of the slot of the second connector 42 is provided with an outward flange 420, which overlaps and is fixed to the upper beam 3 of the forward cabin, increasing the contact area of ​​the overlap and ensuring the connection strength and reliability under stress.

[0038] In addition, the front cabin reinforcing beam 4 is provided with a first mounting part 401 and a second mounting part 402. The first mounting part 401 is used to fix the headlight, and the second mounting part 402 is used to fix the washer fluid filling pipe. The front cabin reinforcing beam 4 is also provided with a first support 403 and a second support 404. The first support 403 is used to fix the headlight cover buffer plug, and the second support 404 is used to fix the headlight cover support rod clip. The front cabin reinforcing beam 4 is provided with a first mounting part 401, a second mounting part 402, a first support 403, and a second support 404, which respectively meet the fixing requirements of the headlight, the washer fluid filling pipe, the headlight cover buffer plug, and the headlight cover support rod clip.

[0039] The automobile of this utility model embodiment includes a front body compartment structure. The front body compartment structure is the same as the specific embodiments of the front body compartment structure in the above-described utility model, and will not be repeated here.

[0040] The above description is only a preferred embodiment of the present utility model.
