Description

Technical Field

[0001] The present application relates to the field of vehicle manufacturing technology, and in particular to a floor beam reinforcement structure and a vehicle. Background Art

[0002] In the latest 2024 version of the China-NCAP (C-NCAP), new energy vehicles must meet not only side pole collisions but also side movable barrier collisions. The frontal collision speed has also been increased from 50 kph to 56 kph, increasing the impact energy by approximately 25%. Due to the presence of three-electric systems, such as the battery pack, new energy vehicles are generally heavier than fuel vehicles. Furthermore, due to iterative updates to regulations, in addition to protecting occupant safety, the safety of high-voltage systems, such as the battery pack, must also be ensured in a collision. Existing new energy vehicles have greater initial kinetic energy than traditional fuel vehicles in various regulatory collision test conditions, impacting the safety of occupants and the battery pack, necessitating further strengthening of the vehicle body structure.

[0003] In a head-on collision, the impact force of the collision is transmitted from the front longitudinal beam to the passenger compartment and then to the front seat crossbeam through the rear cover, causing the front seat crossbeam to bend along the length of the vehicle body, encroaching on the occupants' safety space; in side pole collisions and side movable barrier collisions, the occupants and battery packs will be squeezed due to side intrusion, and the front seat crossbeam will also bend downward along the height of the vehicle body, posing a risk of squeezing the battery pack.

[0004] Therefore, it is necessary to design a floor beam reinforcement structure to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the defects of the existing technology, the utility model provides a floor beam reinforcement structure and a vehicle, which effectively solves the problem that existing new energy vehicles do not meet the safety requirements of frontal collision and side collision.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0026] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the product of the application is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0027] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0028] In the description of the embodiments of the present application, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] According to a first aspect of the present invention, a floor beam reinforcement structure is provided. Figures 1 to 5 As shown, this floor cross member reinforcement structure is used in a vehicle floor assembly. The floor assembly includes a central tunnel (not shown) located in the middle. The central tunnel can be an existing component of the vehicle floor assembly, and its structure is well known to those skilled in the art. The floor cross member reinforcement structure can be connected to the central tunnel and serve as part of the floor assembly. The floor cross member reinforcement structure includes a cross member body 1, a first reinforcement member 2, and a second reinforcement assembly.

[0030] In the following description, reference will be made to Figures 1 to 5 The detailed structure of the beam body 1, the first reinforcement 2 and the second reinforcement assembly of the floor beam reinforcement structure is described in detail. In addition, in the description of the embodiment, the direction of the beam body 1 will also be mentioned. Since the beam body 1 is approximately a long strip structure, the length direction of the beam body 1 is the length direction of the long strip structure. The length direction can also be understood as the length of the beam body 1. Figure 2 From left to right or from right to left; the width direction of the beam body 1 is the width direction of the long strip structure, and the width direction can also be understood as Figure 2 The direction from top to bottom or from bottom to top.

[0031] like Figure 1 As shown in the embodiment, the crossbeam body 1 includes a first bent portion 101 and an extension portion 102. The arrangement of the first bent portion 101 and the extension portion 102 enables the crossbeam body 1 to cooperate with the above-mentioned floor assembly and ensures that the crossbeam body 1 can ensure its own strength. The first bent portion 101 protrudes upward relative to the extension portion 102. The upward here refers to Figure 1 Furthermore, in the fully assembled floor assembly, the central tunnel is also located above the crossmember body 1. The crossmember body 1 provides support and reinforcement for the floor assembly and the central tunnel. Therefore, to ensure support strength, the first bent portion 101 is bent toward the central tunnel, and the extensions 102 are correspondingly positioned at both ends of the first bent portion 101.

[0032] Furthermore, if Figure 2 As shown, Figure 2 for Figure 1 The structural diagram is viewed from an upward angle, wherein the first reinforcement 2 is arranged on the side of the first bend portion 101 facing away from the central channel. The shape of the first reinforcement 2 corresponds to the shape of the first bend portion 101. The first reinforcement 2 is an additional reinforcement provided for the floor crossbeam reinforcement structure, which can enhance the strength of the first bend portion 101 of the crossbeam body 1. The first reinforcement 2 can resist side intrusion in side column collision and side movable barrier collision, protect the occupants and the battery pack from being squeezed, and prevent the risk of the crossbeam body 1 being bent downward in the vertical direction of the vehicle and squeezing the battery pack due to the extrusion force in a side impact.

[0033] Further, if Figure 2 and Figure 3 As shown, the second reinforcement component is provided on the side of the extension 102 facing away from the central channel, and the second reinforcement component is connected to the first reinforcement 2. Due to the long length of the crossbeam body 1, a single first reinforcement 2 cannot fully reinforce the crossbeam body 1. The extension 102 of the crossbeam body 1 needs to be strengthened. Therefore, a second reinforcement component is additionally provided at the extension 102. In addition, in a frontal collision, the impact force of the collision is transmitted to the passenger compartment by the front longitudinal beam, and the second reinforcement component is provided by the front longitudinal beam. Figure 2 The longitudinal beam cover 4 shown is transferred to the cross beam body 1. The second reinforcement component can prevent the cross beam body 1 from bending along the direction from the front to the rear of the vehicle (i.e., along the width direction of the cross beam body 1) in a frontal collision, thereby preventing the bending from invading the safety space of the occupants and ensuring the safety of the occupants.

[0034] In summary, the floor cross-beam reinforcement structure, through the cooperation of the cross-beam body 1, the first reinforcement 2, and the second reinforcement assembly, can enhance the structural strength of the cross-beam body 1. The first reinforcement 2 and the second reinforcement assembly are installed on the cross-beam body 1. In the event of a frontal collision, the second reinforcement assembly can enhance the bending resistance of the extension portion 102 of the cross-beam body 1, preventing the cross-beam body 1 from bending after impact from the front to the rear of the vehicle, thus preventing the bent cross-beam body 1 from encroaching on the occupant's safety space and improving the impact resistance of frontal collisions. In the event of a side column collision or a side movable barrier collision, the first reinforcement 2 can enhance the bending resistance of the first bent portion 101 of the cross-beam body 1, preventing the cross-beam body 1 from bending downward along the height of the vehicle body after impact from the side of the vehicle, thereby risking battery pack compression. The overall structure of the floor cross-beam reinforcement structure is simple, easy to produce and assemble, and can simultaneously ensure the safety of the occupants and battery pack of new energy vehicles, protecting them from frontal and side impacts and ensuring personal safety during driving.

[0035] Preferably, if Figure 3As shown, in an embodiment, the first reinforcement 2 may include a straight portion 201 and an inclined connection portion 202. The straight portion 201 corresponds to the first bend portion 101. In order to facilitate assembly, the middle portion of the first bend portion 101 is straight, so the first reinforcement 2 is provided with a straight portion 201 to correspond to the shape of the first bend portion 101. Since the first bend portion 101 is formed to be convex, the inclined connection portion 202 can correspond to the remaining structure of the first bend portion 101 except the straight middle portion to ensure the reliability of increased strength. The first end of the inclined connection portion 202 is connected to the straight portion 201, and the second end of the inclined connection portion 202 is connected to the second reinforcement assembly. Here, the first end and the second end of the inclined connection portion 202 may refer to the first end and the second end in the length direction, that is, in Figure 2 Due to the arrangement of the straight portion 201 and the inclined connecting portion 202, the shape of the first reinforcement member 2 can correspond to the first bent portion 101 to best increase the structural strength.

[0036] Preferably, if Figure 3 As shown, in this embodiment, the straight portion 201 is provided with a first reinforcement groove 203, and the inclined connecting portion 202 is provided with a second reinforcement groove 204. Both the first reinforcement groove 203 and the second reinforcement groove 204 are recessed away from the central channel. The first reinforcement groove 203 and the second reinforcement groove 204 can respectively increase the bending resistance of the straight portion 201 and the inclined connecting portion 202, thereby further improving the bending resistance of the beam body 1.

[0037] Preferably, if Figures 2 to 4 As shown, in this embodiment, the second reinforcement assembly may include a second bend portion, the second bend portion bending in the opposite direction to the first bend portion 101. The second bend portion and the first bend portion 101 arranged in opposite directions enable the crossbeam body 1 to achieve bending resistance in two different directions. Furthermore, in actual production and assembly, to ensure sufficient welding space when the floor crossbeam reinforcement structure is assembled with the remaining components of the floor assembly, the second bend portion of the second reinforcement assembly is bent in the opposite direction to the first bend portion 101 to facilitate assembly.

[0038] Preferably, if Figures 1 to 4 As shown, in this embodiment, each end of the straight portion 201 is connected to an inclined connection portion 202. There are two inclined connection portions 202, one at each end of the straight portion 201. The second reinforcement assembly includes a first bracket 301 and a second bracket 302, each connected to the two inclined connection portions 202. In this way, the first bracket 301 and the second bracket 302 can enhance the bending resistance of the two inclined connection portions 202.

[0039] Preferably, if Figure 3 As shown, in the embodiment, the first bracket 301 and the second bracket 302 each include a reinforced bottom surface 303 and support legs 304. The support legs 304 are provided at both ends of the reinforced bottom surface 303. The first bracket 301 and the second bracket 302 are both connected to the inclined connection portion 202 via the support legs 304. The connection method can be welding. The edges of the support legs 304 are formed with flanges, which are welded to the remaining structures via the flanges. A reinforced bottom surface 303 is provided with a support leg 304 at both ends in the length direction of the beam body 1. The two support legs 304 and the reinforced bottom surface 303 can form a bracket structure, namely the first bracket 301 and the second bracket 302. The reinforced bottom surface 303 plays the role of support, structural reinforcement and anti-bending, and the support legs 304 can play the role of connection and auxiliary support.

[0040] Preferably, if Figure 4 and Figure 5 As shown, in this embodiment, the crossbeam body 1 may further include a first outer edge portion 103, which is disposed at both ends of the crossbeam body 1 in the width direction. The crossbeam body 1 can be mounted to the floor assembly via the first outer edge portion 103, either by welding or using fastening bolts. To correspond to the shape of the crossbeam body 1 and to facilitate mounting thereof, the first reinforcement member 2 includes a second outer edge portion 205, the location of which corresponds to that of the first outer edge portion 103. Furthermore, the shape and size of the second outer edge portion 205 also correspond to those of the first outer edge portion 103.

[0041] Preferably, if Figures 1 to 4 As shown, in this embodiment, the floor assembly may further include a longitudinal beam cover plate 4 connected to the crossbeam body 1. The second reinforcement assembly is positioned correspondingly to the longitudinal beam cover plate 4. While enhancing the crossbeam body 1's bending resistance, the second reinforcement assembly also protects the longitudinal beam cover plate 4 from impact forces that could directly strike the crossbeam body 1 during a head-on collision, thereby preventing the crossbeam body 1 from bending along the length of the vehicle body and encroaching on the occupant's safety space. Furthermore, the dimensions of the second reinforcement assembly are substantially identical to those of the longitudinal beam cover plate 4, ensuring that any impact forces from the longitudinal beam cover plate 4 are first transferred to the second reinforcement assembly and then to the crossbeam body 1, thereby increasing the crossbeam body 1's bending resistance.

[0042] Preferably, if Figure 5As shown, in the embodiment, the crossbeam body 1 may further include a top portion 104 and a support portion 105. The top portion 104 can be understood as the top surface, and the support portion 105 can be understood as the side surface along the length direction of the crossbeam body 1. That is, the support portion 105 is provided at both ends of the top portion 104 in the width direction of the crossbeam body 1, and the two support portions 105 are arranged facing each other. The top portion 104 and the two support portions 105 can be enclosed to form a U-shaped structure, and an installation position is formed inside the U-shaped structure. Both the first reinforcing member 2 and the second reinforcing component are provided inside the installation position. <00001......(It seems the content of ID=2 is incomplete. Please check and provide the full text for a complete translation.) When assembling this floor crossbeam strengthening structure, the first bracket 301 and the second bracket 302 can be first welded to the installation position of the crossbeam body 1, and the first bracket 301 and the second bracket 302 can be made to correspond to the extension portion 102 of the crossbeam body 1 and the longitudinal beam cover plate 4. Then the first reinforcing member 2 is welded to the first bending portion 101 of the crossbeam body 1. The assembled floor crossbeam strengthening structure can form a floor assembly with the remaining components of the floor assembly. Since the overall shape of this floor crossbeam strengthening structure is not changed, the first reinforcing member 2, the first bracket 301 and the second bracket 302 can be first installed on the crossbeam body 1 and then assembled on the existing production line. Therefore, there is no need to additionally increase the production rhythm, no need to build an additional production line, and the production cost is reduced.

[0044] Through the cooperation of the crossbeam body, the first reinforcing member and the second reinforcing component, this floor crossbeam strengthening structure can improve the structural strength of the crossbeam body. The first reinforcing member and the second reinforcing component are installed on the crossbeam body. When the vehicle is subjected to a frontal collision, the second reinforcing component can improve the anti-bending force of the extension portion of the crossbeam body, avoid the crossbeam body being bent after being impacted from the front of the vehicle to the rear, avoid the bent crossbeam body invading the safety space of the occupant, and improve the anti-impact ability of the frontal collision; when the vehicle is subjected to a side pillar collision and a side moving barrier collision, the first reinforcing member can improve the anti-bending force of the first bending portion of the crossbeam body, avoid the crossbeam body being bent downward along the height direction of the vehicle body after being impacted from the side of the vehicle body, and thus avoid the risk of squeezing the battery pack. This floor crossbeam strengthening structure has a simple overall structure, is convenient for production and assembly, and can ensure the safety of the occupants and the battery pack of new energy vehicles, avoid being impacted from the front and side, and ensure personal safety during driving.

[0045] In addition, according to the second aspect of the present invention, a vehicle is provided, and the vehicle includes the above-mentioned floor crossbeam strengthening structure. During the use of this vehicle, through the floor crossbeam strengthening structure, the anti-impact ability of the vehicle during frontal collision and side collision can be increased, avoid the crossbeam body 1 being bent and invading the safety space of the occupant and the battery pack, and improve the safety and anti-impact performance of the vehicle.
