[0024] The front-end frame is the core load-bearing structural assembly of the front of a car body, often referred to as the "front frame" or "front bulkhead frame." Located within the engine compartment, it serves as the basic platform connecting various components of the front of the vehicle and is crucial for vehicle safety, handling, and maintenance economy. During actual production and research and development, researchers have found that in traditional vehicle front-end frames, the structure is relatively fixed, making it difficult to accommodate vehicles with different front overhang lengths. This significantly limits the compatibility of the front-end frame.

[0025] This invention proposes a front-end framework and vehicle, aiming to solve the technical problem of poor compatibility in front-end frameworks.

[0026] Please see Figure 1 and Figure 2In one embodiment of the present invention, the front-end frame is applied to a vehicle. The front-end frame includes a frame body 100 and a support mechanism 200. The frame body 100 includes an upper curved beam 110, a lower curved beam 120, a crash beam 130, and two uprights 140. The lower curved beam 120 and the upper curved beam 110 are arranged sequentially from low to high along the height direction of the vehicle. The two ends of the lower curved beam 120 and the upper curved beam 110 are respectively connected to the two uprights 140. The crash beam 130 includes a beam body 131 and two mounting seats 132 connected to the two ends of the beam body 131. The two mounting seats 132 are respectively disposed on the two uprights 140. The support mechanism 200 includes a first crossbeam 210 and two support components 220. The two support components 220 are arranged along the vehicle... The support components 220 are spaced apart in the left and right directions and are correspondingly set one-to-one with the two mounting seats 132. Each support component 220 includes a first support beam 221 and a second support beam 222 that are connected to each other. The end of the first support beam 221 away from the second support beam 222 is connected to the upper curved beam 110, and the end of the second support beam 222 away from the first support beam 221 is connected to the corresponding mounting seat 132. A first crossbeam 210 is set above the beam body 131 and connects the second support beams 222 of the two support components 220. Each second support beam 222 has multiple mounting positions spaced apart in the front and rear directions of the vehicle. Each second support beam 222 can switch between multiple mounting positions simultaneously to adapt to vehicles with different front overhang lengths. The first crossbeam 210 is used to mount the front skin of the vehicle.

[0027] The technical solution of this invention, by setting a support mechanism 200 above the anti-collision beam 130 and setting the second support beam 222 to be position adjustable, enables the front-end frame to adapt to vehicles with different front overhang lengths, thereby improving the compatibility of the front-end frame. In this embodiment, the frame body 100 constitutes the basic skeleton of the front-end frame, providing an installation and load-bearing platform for various components at the front of the vehicle; the upper curved beam 110 and the lower curved beam 120 serve as the main lateral supports of the front-end frame, located at the top and bottom of the frame, respectively; the column 140 connects the upper curved beam 110 and the lower curved beam 120 to form the left and right side skeletons of the frame; the anti-collision beam 130 is used to absorb and disperse collision energy when a vehicle collision occurs. The support mechanism 200 supports the front skin and includes a first crossbeam 210 and two support components 220. Each support component 220 includes a first support beam 221 and a second support beam 222 connected to each other. The first support beam 221 connects the upper curved beam 110 and the second support beam 222, and is used to transfer the supporting force from the upper curved beam 110 to the anti-collision beam 130 area, thereby improving the rigidity and stability of the front-end frame. By making the position of each second support beam 222 adjustable along the longitudinal direction of the vehicle, the front-end frame can adapt to vehicles with different front overhang lengths, thus improving the compatibility of the front-end frame. Specifically, when assembling vehicles with different front overhang lengths, the position of the second support beam 222 can be adjusted according to actual needs to ensure effective support of the front skin by the front-end frame, thereby ensuring the stability of the overall vehicle structure. This front-end frame is applied in the field of vehicle technology.

[0028] It should be noted that in this embodiment, the first crossbeam 210 provides a support platform for the installation of the front skin. By setting the support mechanism 200 above the anti-collision beam 130, the mounting point of the front skin can be installed on the first crossbeam 210 during the installation of the front skin, thereby providing effective support for the front skin and ensuring the stability of the overall vehicle structure.

[0029] Please see Figure 3 and Figure 4In one embodiment of the present invention, the first support beam 221 is provided with a plurality of first mounting holes 221a spaced apart along the front-rear direction of the vehicle, the top of the second support beam 222 is provided with a plurality of second mounting holes 222a spaced apart along the front-rear direction of the vehicle, the mounting base 132 is provided with a plurality of third mounting holes 132a spaced apart along the front-rear direction of the vehicle, and the bottom of the second support beam 222 is provided with a fourth mounting hole. The number of mounting positions, first mounting holes 221a, and third mounting holes 132a are equal and correspond one-to-one. The support assembly 220 also includes a first fastener 2. 23 and 224; When the second support beam 222 is in any installation position, one of the second mounting holes 222a is aligned with the corresponding first mounting hole 221a, and the fourth mounting hole is aligned with the corresponding third mounting hole 132a. The first fastener 223 passes through one of the second mounting holes 222a and the corresponding first mounting hole 221a and connects the second support beam 222 and the first support beam 221. The second fastener 224 passes through the fourth mounting hole and the corresponding third mounting hole 132a and connects the second support beam 222 and the mounting base 132. Both the first fastener 223 and the second fastener 224 can be bolts. In this embodiment, by providing multiple first mounting holes 221a on the first support beam 221 and multiple second mounting holes 222a on the mounting base 132, and fixing both ends of the first support beam 221 with bolts, the position of the second support beam 222 can be adjusted to adapt to the installation requirements of vehicles with different front overhang lengths. Furthermore, it ensures the structural strength of the front frame, thereby guaranteeing the stability of the overall vehicle structure. Specifically, when assembling vehicles with different front overhang lengths, the second support beam 222 is first adjusted to the required installation position, and the second mounting hole 222a is aligned with the corresponding first mounting hole 221a, and the fourth mounting hole is aligned with the corresponding third mounting hole 132a. Then, the first fastener 223 is passed through the second mounting hole 222a and the corresponding first mounting hole 221a and connected to the top of the first support beam 221. The second fastener 224 is then passed through the fourth mounting hole and the corresponding third mounting hole 132a and connected to the second support beam 222 and the mounting base 132. In one specific embodiment, a connecting plate is bolted to the top of the second support beam 222, and the second mounting hole 222a is formed on the connecting plate.

[0030] Please see Figure 3 and Figure 4In one embodiment of the present invention, the top surface and both sides of the second support beam 222 are provided with second mounting holes 222a, and the top surface and both sides of the first support beam 221 are provided with multiple first mounting holes 221a at intervals along the front-rear direction of the vehicle. There are multiple first fasteners 223, and the number of first fasteners 223 and second mounting holes 222a are equal and correspond one-to-one. When the second support beam 222 is in any installation position, each second mounting hole 222a is aligned with the corresponding first mounting hole 221a, and each first fastener 223 passes through the corresponding second mounting hole 222a and the corresponding first mounting hole 221a and connects the second support beam 222 and the first support beam 221. Specifically, after adjusting the second support beam 222 to the desired installation position, fixing the top of the second support beam 222 with multiple first fasteners 223 ensures the reliability of the connection between the second support beam 222 and the first support beam 221, thereby ensuring the structural strength of the front frame. Correspondingly, the number of fourth mounting holes can be set to multiple to ensure the reliability of the second support beam 222 when connected to the mounting base 132, thereby ensuring the structural strength of the front frame.

[0031] In one embodiment of the present invention, the first crossbeam 210 has multiple height positions spaced apart along the height direction of the vehicle; the first crossbeam 210 can switch between multiple height positions to adapt to front skins with different installation heights. In this embodiment, the installation height of the front skin will also be different for different vehicle models. By setting the first crossbeam 210 to be adjustable along the height direction of the vehicle, the first crossbeam 210 can adapt to front skins with different installation heights, improving the compatibility of the front-end frame.

[0032] Please see Figure 4 In one embodiment of the present invention, each second support beam 222 is provided with a plurality of first connecting holes 222c at intervals along the height direction of the vehicle, and each end of the first crossbeam 210 is provided with a second connecting hole. The number of first connecting holes 222c and the height position are equal and correspond one-to-one. The front frame also includes a locking member 211. When the first crossbeam 210 is at any height position, each second connecting hole is aligned with the corresponding first connecting hole 222c, and the locking member 211 passes through the corresponding second connecting hole and the corresponding first connecting hole 222c and connects the first crossbeam 210 and the support assembly 220. The locking member 211 can be a bolt. In this embodiment, by providing a plurality of first connecting holes 222c on the second support beam 222 and fixing both ends of the first crossbeam 210 with bolts, the position of the first crossbeam 210 can be adjusted to adapt to the front skin at different installation heights, and the structural strength of the front frame can be guaranteed, thereby ensuring the stability of the overall vehicle structure.

[0033] Please see Figure 1 and Figure 2 In one embodiment of the present invention, each first support beam 221 extends along the front-rear direction of the vehicle, and each second support beam 222 extends along the height direction of the vehicle. In this embodiment, the first support beam 221 is designed to extend along the front-rear direction of the vehicle, and the second support beam 222 is designed to extend along the height direction of the vehicle; this enables the corresponding first support beam 221, the corresponding second support beam 222, the corresponding mounting base 132, and the corresponding column 140 to enclose a rectangular frame space, thereby improving the structural strength of the frame structure and ensuring the stability of the overall vehicle structure. In addition, the first crossbeam 210, the beam body 131, and the second support beam 222 of the two support components 220 enclose a rectangular frame space, and the first crossbeam 210, the upper curved beam 110, and the two support components 220 enclose a rectangular frame space, which also improves the structural strength of the frame structure and ensures the stability of the overall vehicle structure.

[0034] Please see Figure 4 In one embodiment of the present invention, the support mechanism 200 further includes a second crossbeam 230, the two ends of which are respectively connected to the first support beams 221 of the two support components 220. In this embodiment, by setting the second crossbeam 230 between the first support beams 221 of the two support components 220, the rectangular frame space enclosed by the first crossbeam 210, the upper curved beam 110, and the two support components 220 can be divided into two smaller rectangular frame spaces, thereby improving the structural strength of the frame structure.

[0035] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the front frame further includes a protective mechanism 300, which is disposed below the beam 131 and used to support the bottom of the front skin. In this embodiment, by providing a protective mechanism 300 below the beam 131 to support the bottom of the front skin, it can better protect pedestrians and reduce the injuries caused by the collision when the front of the vehicle collides with a pedestrian.

[0036] Please see Figure 1In one embodiment of the present invention, the protective mechanism 300 includes a protective beam 310, two first connecting plates 320, and two second connecting plates 330. The protective beam 310 is disposed below the beam body 131. The two first connecting plates 320 are spaced apart along the left-right direction of the vehicle and each connects the protective beam 310 and the beam body 131. The two second connecting plates 330 are correspondingly disposed at two mounting seats 132, and are respectively disposed at both ends of the protective beam 310 and connected to the corresponding mounting seats 132. In this embodiment, the protective beam 310 is used to absorb and disperse collision energy when the front of the vehicle collides with a pedestrian, thereby reducing the injury suffered by the pedestrian due to the collision. In addition, the protective beam 310, the beam body 131, and the two first connecting plates 320 enclose a rectangular frame space, which can improve the structural strength of the front frame. In one specific embodiment, both second connecting plates 330 are inclined from the side away from the vehicle's central axis to the side closer to the vehicle's central axis along the direction from the front to the rear of the vehicle. This allows the protective beam 310 and the second connecting plate 330 to form a triangular frame space, thereby improving the structural strength of the front frame.

[0037] The present invention also proposes a vehicle that includes the aforementioned front-end frame. The specific structure of the front-end frame is as described in the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0038] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
