[0002] As people's living standards improve, cars have become an indispensable means of transportation. Vehicle safety has become a crucial factor in car selection. When a vehicle is impacted, its internal frame transmits and disperses the collision force to prevent severe damage and passenger injury. Existing vehicle frames typically include A-pillars, B-pillars, C-pillars, and D-pillars. The D-pillar, located at the rear of the vehicle, connects to the front crossbeam of the cargo area and the side beams. Furthermore, a rear longitudinal beam is located below the D-pillar. The significant distance between the D-pillar, the front crossbeam of the cargo area, and the side beams and the rear longitudinal beam results in poor force transmission, weakening the rear of the vehicle and making it susceptible to severe damage after a collision. This compromises safety and leaves room for improvement. Summary of the Invention

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying 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 with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following is for reference. Figures 1-2 The vehicle body frame 100 described in this embodiment of the invention has good force transmission effect, can increase the strength of the rear side of the vehicle body, and improve vehicle safety performance.

[0026] like Figures 1-2 As shown, the vehicle body frame 100 according to an embodiment of the present invention includes: a D-pillar 1, a front crossbeam 2 of the shelf, a reinforcing beam 4, and a support beam assembly 6.

[0027] The body D-pillar 1 is located between the roof side beam 7 and the body side beam 3. The body D-pillar 1 extends along the height of the body. The end of the front crossbeam 2 of the shelf is connected to the body D-pillar 1. The front crossbeam 2 of the shelf extends along the left and right direction of the body. The reinforcing beam 4 is located between the body D-pillar 1 and the roof side beam 7. The reinforcing beam 4 is located above the body side beam 3 and spaced apart from the body side beam 3. The reinforcing beam 4 extends along the front and rear direction of the body. The upper part of the support beam assembly 6 is connected to the reinforcing beam 4 and / or the front crossbeam 2 of the shelf, and the lower part is connected to the rear longitudinal beam 5 of the body.

[0028] The vehicle consists of A-pillars, B-pillars, C-pillars, and D-pillars. The D-pillar is the pillar between the last side window and the rear windshield. It mainly supports and withstands side impacts. In the event of an accident, it can protect the side safety of the occupants. Therefore, the D-pillar has high strength requirements to ensure that it can withstand side impacts while protecting the safety of the occupants.

[0029] Specifically, the roof side beam 7 is located on both sides of the vehicle body and is arched along the front-rear direction of the vehicle body to give the vehicle body an arched structure. The side beam 3 is located on both sides of the vehicle body and is arranged along the front-rear direction of the vehicle body. The rearward end of the roof side beam 7 along the vehicle body direction is connected to the rearward end of the side beam 3 along the vehicle body direction. The front crossbeam 2 of the shelf is transversely located in the vehicle body frame 100 and extends along the left-right direction of the vehicle body. There are two D-pillars 1 of the vehicle body, and the D-pillars 1 are vertically located on both sides of the front crossbeam 2 of the shelf and are connected to the front crossbeam 2 of the shelf by means of MIG welding or other methods. The lower end of the D-pillar 1 is connected to... The side beam 3 of the vehicle body is connected by MIG welding and other methods. A reinforcing beam 4 is provided between the body D-pillar 1 and the side beam 3. The reinforcing beam 4 is set parallel to the side beam 3 and extends along the front and rear direction of the vehicle body. The reinforcing beam 4 is set between the body D-pillar 1 and the roof side beam 7. The front crossbeam 2 of the shelf is set perpendicular to the inner side of the body D-pillar 1 facing the vehicle body. The reinforcing beam 4 is set perpendicular to the adjacent surface of the connecting surface between the body D-pillar 1 and the front crossbeam 2 of the shelf. The body D-pillar 1 is a rectangular column and its adjacent surfaces are perpendicular to each other. Therefore, the reinforcing beam 4 is set perpendicular to the front crossbeam 2 of the shelf.

[0030] Meanwhile, the vehicle frame 100 is also equipped with a support beam assembly 6. The upper part of the support beam assembly 6 is connected to the reinforcing beam 4 and / or the front crossbeam 2 of the shelf. That is, the upper part of the support beam assembly 6 is connected to the reinforcing beam 4 and the front crossbeam 2 of the shelf, or the upper part of the support beam assembly 6 is only connected to the reinforcing beam 4, or the upper part of the support beam assembly 6 is only connected to the front crossbeam 2 of the shelf. When the upper part of the support beam assembly 6 is connected to both the reinforcing beam 4 and the front crossbeam 2 of the shelf, the upper part of the support beam assembly 6 forms a right triangle with the reinforcing beam 4 and the front crossbeam 2 of the shelf, which has stability, thereby improving the strength of the vehicle frame 100 and improving vehicle safety. The lower part of the support beam assembly 6 is connected to the rear longitudinal beam 5 of the vehicle body.

[0031] Furthermore, when the vehicle is impacted from the side and rear, the outermost body D-pillar 1, body side beam 3, and reinforcing beam 4 of the body frame 100 are the first to be subjected to force. The impact force can be transmitted through the body D-pillar 1 to the front crossbeam 2 of the shelf, then through the front crossbeam 2 of the shelf to the support beam assembly 6, and then through the support beam assembly 6 to the rear longitudinal beam 5 of the body. The impact force can also be directly transmitted through the reinforcing beam 4 to the support beam assembly 6, and then through the support beam assembly 6 to the rear longitudinal beam 5 of the body. This gives the impact force multiple transmission paths, thereby dispersing the impact force, improving the structural strength of the body frame 100, and ensuring the safety of the vehicle.

[0032] According to an embodiment of the present invention, the vehicle frame 100 connects the reinforcing beam 4, the front crossbeam 2 of the shelf, and the rear longitudinal beam 5 of the vehicle body by setting the support beam assembly 6. This ensures the force transmission effect when the rear side of the vehicle body is subjected to collision force, increases the strength of the rear side of the vehicle body, and improves the vehicle safety performance. It has better performance and a wider range of applications.

[0033] In some embodiments, the support beam assembly 6 includes a transverse support beam 61 and a lower support beam 62. The two ends of the transverse support beam 61 are connected to the reinforcing beam 4 and the front crossbeam 2 of the shelf, respectively, and the two ends of the lower support beam 62 are connected to the transverse support beam 61 and the rear longitudinal beam 5 of the vehicle body, respectively.

[0034] Specifically, such as Figure 1 As shown, the support beam assembly 6 is used to transfer the force on the body D-pillar 1 and the reinforcing beam 4 to the rear longitudinal beam 5 of the body to improve the structural strength of the body frame 100. The support beam assembly 6 is provided with a transverse support beam 61 and a lower support beam 62. The transverse support beam 61 is connected to the lower support beam 62 and is located above the lower support beam 62. One end of the transverse support beam 61 is connected to the reinforcing beam 4 and the other end is connected to the front crossbeam 2 of the shelf. The upper end of the lower support beam 62 is connected to the transverse support beam 61 and the lower end is connected to the rear longitudinal beam 5 of the body.

[0035] Furthermore, the transverse support beam 61 is connected to the reinforcing beam 4 and the front crossbeam 2 of the shelf, forming a right-angled triangle. The right-angled triangle has stability, thereby improving the strength of the vehicle frame 100. The lower support beam 62 is set to be perpendicular to the transverse support beam 61. The transverse support beam 61, the lower support beam 62 and the rear longitudinal beam 5 of the vehicle body form an "I" shaped structure, which has stability and can further improve the strength of the vehicle frame 100 and improve vehicle safety.

[0036] In some embodiments, such as Figure 1 As shown, the front end of the horizontal support beam 61 has a first mating end face, which is mated and connected to the rear side of the front crossbeam 2 of the shelf; and / or, the rear end of the horizontal support beam 61 has a second mating end face, which is mated and connected to the inner side of the reinforcing beam 4.

[0037] The front end of the horizontal support beam 61 has a first contact end face, which is in contact with the rear side of the front crossbeam 2 of the shelf. The rear end of the horizontal support beam 61 has a second contact end face, which is in contact with the inner side of the reinforcing beam 4. Alternatively, only the front end of the horizontal support beam 61 has a first contact end face, which is in contact with the rear side of the front crossbeam 2 of the shelf, or only the rear end of the horizontal support beam 61 has a second contact end face, which is in contact with the inner side of the reinforcing beam 4.

[0038] Specifically, there is an angle between the horizontal support beam 61 and the reinforcing beam 4 and the front crossbeam 2 of the shelf, that is, the horizontal support beam 61 is obliquely set between the reinforcing beam 4 and the front crossbeam 2 of the shelf. The horizontal support beam 61, the reinforcing beam 4 and the front crossbeam 2 of the shelf are all rectangular beams. The front end of the horizontal support beam 61 is provided with a first contact end face and the rear end is provided with a second contact end face, which makes the horizontal support beam 61 more firmly connected with the reinforcing beam 4 and the front crossbeam 2 of the shelf, improves the strength of the connection, and the surface increases the area of ​​the connection, resulting in better force transmission.

[0039] In some embodiments, such as Figure 1 As shown, the angle between the horizontal support beam 61 and the reinforcing beam 4 is the same as the angle between the horizontal support beam 61 and the front crossbeam 2 of the shelf.

[0040] Specifically, the transverse support beam 61 is connected to the reinforcing beam 4 and the front crossbeam 2 of the shelf, forming a right triangle. The included angle between the transverse support beam 61 and the reinforcing beam 4 is the same as the included angle between the transverse support beam 61 and the front crossbeam 2 of the shelf, that is, the two acute angles of the right triangle are the same, making the right triangle an isosceles right triangle. The collision force on the D-pillar 1 of the vehicle body has the same path length when it is transmitted through the reinforcing beam 4 and the front crossbeam 2 of the shelf, respectively, so that the force on both ends of the transverse support beam 61 is uniform, avoiding deformation of the transverse support beam 61 due to uneven force, which would affect the structural strength of the vehicle body frame 100.

[0041] In some embodiments, the upper end of the lower support beam 62 is formed with a third mating end face, which is mated and connected to the lower side of the transverse support beam 61; and / or, the lower end of the lower support beam 62 is formed with a fourth mating end face, which is mated and connected to the upper side of the rear longitudinal beam 5 of the vehicle body.

[0042] The lower support beam 62 has a third mating end face at its upper end, which is mated and connected to the lower side of the transverse support beam 61. The lower support beam 62 also has a fourth mating end face at its lower end, which is mated and connected to the upper side of the rear longitudinal beam 5 of the vehicle body. Alternatively, only the upper end of the lower support beam 62 may have a third mating end face, which is mated and connected to the lower side of the transverse support beam 61. Or only the lower end of the lower support beam 62 may have a fourth mating end face, which is mated and connected to the upper side of the rear longitudinal beam 5 of the vehicle body.

[0043] Specifically, the lower support beam 62 has an included angle with the transverse support beam 61 and the rear longitudinal beam 5 of the vehicle body. That is, the lower support beam 62 is obliquely set between the transverse support beam 61 and the rear longitudinal beam 5 of the vehicle body. The lower support beam 62, the transverse support beam 61 and the rear longitudinal beam 5 of the vehicle body are all rectangular beams. The upper end of the lower support beam 62 is provided with a third fitting end face and the lower end is provided with a fourth fitting end face. This makes the lower support beam 62 more firmly connected with the transverse support beam 61 and the rear longitudinal beam 5 of the vehicle body, improves the strength of the connection, and the surface increases the area of ​​the connection, resulting in better force transmission.

[0044] In some embodiments, such as Figure 1 As shown, the upper end of the lower support beam 62 is connected to the middle part of the transverse support beam 61.

[0045] Specifically, when the vehicle is impacted from the side and rear, the impact force can be transmitted through the D-pillar 1 to the front crossbeam 2 of the shelf, then through the first mating surface to the transverse support beam 61, and then through the transverse support beam 61 to the lower support beam 62. The impact force can also be transmitted directly to the transverse support beam 61 through the second mating surface connected to the reinforcing beam 4, and then through the transverse support beam 61 to the lower support beam 62. The upper end of the lower support beam 62 is connected to the middle of the transverse support beam 61. That is, the distance from the first mating surface to the lower support beam 62 when the impact force is transmitted from the first mating surface and the second mating surface is the same, so as to avoid the transverse support beam 61 from deforming due to uneven force, which would affect the structural strength of the vehicle frame 100.

[0046] In some embodiments, such as Figure 1 As shown, the lower support beam 62 is set to tilt backward from top to bottom, that is, there is an angle between the lower support beam 62 and the rear longitudinal beam 5 of the vehicle body.

[0047] Specifically, when the vehicle is impacted from the side and rear, the collision force can be transmitted through the D-pillar 1 to the front crossbeam 2 of the shelf, and then through the transverse support beam 61 to the lower support beam 62. The collision force can also be transmitted through the reinforcing beam 4 to the transverse support beam 61, and then through the transverse support beam 61 to the lower support beam 62. The collision force transmitted to the lower support beam 62 can be transmitted to the rear longitudinal beam 5 of the vehicle body. The collision force can be transmitted along the rear longitudinal beam 5 to the front of the vehicle body or to the rear of the vehicle body to disperse the collision force. At the same time, the rear longitudinal beam 5 will also provide an upward reaction force to the lower support beam 62. That is, the rear longitudinal beam 5 will support the lower support beam 62, and then support the transverse support beam 61 to improve the structural strength of the vehicle body frame 100.

[0048] In some embodiments, the support beam assembly 6 is provided with a seat belt retractor mounting point for mounting a seat belt retractor.

[0049] Specifically, the upper part of the support beam assembly 6 is connected to the reinforcing beam 4 and the front crossbeam 2 of the shelf, or the upper part of the support beam assembly 6 is only connected to the reinforcing beam 4, or the upper part of the support beam assembly 6 is only connected to the front crossbeam 2 of the shelf. When the upper part of the support beam assembly 6 is connected to both the reinforcing beam 4 and the front crossbeam 2 of the shelf, the upper part of the support beam assembly 6 forms a right-angled triangle with the reinforcing beam 4 and the front crossbeam 2 of the shelf, which has stability. Installing the seat belt retractor on the support beam assembly 6 through the seat belt retractor mounting point can ensure the reliability of the seat belt retractor installation, thereby ensuring the reliability of the seat belt and improving vehicle safety.

[0050] In some embodiments, the support beam assembly 6 is welded to the reinforcing beam 4, the front crossbeam 2 of the shelf, and the rear longitudinal beam 5 of the vehicle body, respectively. In this embodiment, the support beam assembly 6 is connected to the reinforcing beam 4, the front crossbeam 2 of the shelf, and the rear longitudinal beam 5 of the vehicle body by MIG welding.

[0051] Among them, MIG welding, or inert gas shielded arc welding, is a welding method that uses inert gas to cover the welding part, promotes arc stability and prevents changes in welding quality. The arc heat melts the metal of the welding part, and welding rods are fed in to connect the weld. It has low welding cost, high production efficiency, simple operation, good weld crack resistance, small post-weld deformation and little welding spatter. It can make the support beam assembly 6 less prone to breakage under external impact force after being connected to the reinforcing beam 4, the front crossbeam 2 of the shelf and the rear longitudinal beam 5 of the vehicle body, thus ensuring the firmness of the connection.

[0052] In some embodiments, at least one of the body D-pillar 1, the front crossbeam of the shelf 2, the side beam of the vehicle body 3, the reinforcing beam 4, and the support beam assembly 6 is formed by profile extrusion molding. It is understood that the improved mechanical properties of the extrusion molding process and the full utilization of the plasticity of the material are unmatched by other forging methods, thereby ensuring the quality after connection. Moreover, the time cost consumed during processing is small, the operation is simpler, the manufacturing process is optimized, and the force transmission effect is improved.

[0053] Specifically, in this embodiment, at least one of the following components—the D-pillar 1, the front crossbeam 2 of the shelf, the side beam 3, the reinforcing beam 4, and the support beam assembly 6—can be extruded from profiles, forming cavities in part or all of the body frame. This ensures that the formed body frame 100 can create multiple force transmission channels, providing a force transmission effect and thus improving the overall body strength and rigidity. Furthermore, extruding profiles can reduce the number of parts, allowing at least one of the following components—the D-pillar 1, the front crossbeam 2 of the shelf, the side beam 3, the reinforcing beam 4, and the support beam assembly 6—to be integrated into a single design, reducing the design and development of molds and fixtures, thereby lowering manufacturing costs.

[0054] In this embodiment, the D-pillar 1, the front crossbeam 2 of the shelf, the side beam 3, the reinforcing beam 4, and the support beam assembly 6 can all be made of aluminum alloy. Aluminum alloy is made by adding some alloying elements to pure aluminum. It has better physical and mechanical properties than pure aluminum: it is easy to process, has high durability, wide applicability, good decorative effect, and rich colors. It is also lightweight and easy to process, which makes the vehicle body lighter, saves vehicle energy consumption, makes the vehicle accelerate faster, and reduces vehicle inertia. This avoids situations such as side tilting or increased impact force due to excessive vehicle weight, thus improving safety.
