[0002] The side impact strength of a vehicle is generally weak, and how to strengthen the side structural strength of a vehicle has always been a difficult problem in the design of the vehicle body structure.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0040] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0041] Reference below Figure 1-Figure 5 A rocker beam assembly 100 for a vehicle according to an embodiment of the present application is described.

[0042] The rocker beam assembly 100 of a vehicle includes a rocker inner panel 101 , a rocker outer panel, a reinforcement member 110 and a connection member 120 .

[0043] The rocker inner panel 101 and the rocker outer panel are distributed in the transverse direction of the vehicle, and both extend in the longitudinal direction of the vehicle. The rocker inner panel 101 has a connection surface for connecting with a floor crossbeam of the vehicle, and defines a cavity.

[0044] In this embodiment, the sill inner plate 101 and the sill outer plate both extend in the longitudinal direction of the vehicle, and the sill inner plate 101 and the sill outer plate are recessed in the direction away from each other in the middle of the vertical direction to form a top wall, a side wall and a bottom wall respectively distributed in sequence in the vertical direction, and the sill inner plate 101 and the sill outer plate are connected on the opposite sides in the width direction of the vehicle to form a sill beam of the vehicle and define a cavity. Among them, the sill inner plate 101 has a connecting surface on the side away from the sill outer plate, and the connecting surface is used to connect with the floor beam of the vehicle. It should be noted that the floor beam can be a seat beam of the vehicle, which is used to fix and install the vehicle seat and strengthen the structural strength of the bottom frame of the vehicle in the lateral direction.

[0045] The reinforcement 110 is disposed in the cavity and extends in the longitudinal direction of the vehicle, and the reinforcement 110 is disposed opposite to the connection surface. A plurality of collapse chambers 111 distributed in the transverse direction and / or vertical direction of the vehicle are formed in the reinforcement 110 .

[0046] The reinforcement 110 is provided in the cavity to enhance the structural strength of the threshold beam and improve its bending and torsion resistance. The reinforcement 110 is laterally aligned with the floor crossbeam of the vehicle to improve the structural stability of the force transmission path between the threshold beam and the floor crossbeam. When the vehicle is subjected to a side collision, the force transmission path is not easily failed, so that the floor crossbeam effectively participates in the collision, thereby improving the overall structural strength.

[0047] Among them, a plurality of crush chambers 111 distributed along the transverse and longitudinal directions of the vehicle are formed in the reinforcement 110, and each crush chamber 111 can extend along the longitudinal direction of the vehicle. By arranging a plurality of crush chambers 111 to form a plurality of box-type structures, the structure has high strength and strong deformation resistance, and can effectively resist the crushing force when the vehicle is hit from the side.

[0048] In this embodiment, the reinforcement 110 can be an aluminum alloy extrusion molding setting. The one-piece molding process is simple and light in weight, which is beneficial to the lightweight design of the vehicle. The structure has high strength and is not easy to deform.

[0049] The connecting member 120 is connected to the inner wall surface of the rocker inner panel 101 and the end portion of the reinforcement member 110 in the longitudinal direction of the vehicle.

[0050] The end of the reinforcement member 110 in the longitudinal direction of the vehicle is fixedly connected to the rocker inner panel 101 by providing a connecting member 120 , thereby achieving fixation of the reinforcement member 110 on the rocker inner panel 101 .

[0051] In actual implementation, the connecting member 120 is first installed at the end of the reinforcing member 110 in the longitudinal direction of the vehicle, and then the connecting member 120 is welded to the rocker inner panel 101, which has high assembly efficiency and low process difficulty.

[0052] According to the threshold beam assembly 100 of the embodiment of the present application, the structural strength of the threshold inner panel 101 is improved by providing a reinforcement 110, and the connection member 120 is provided to be welded to the threshold inner panel 101. The reinforcement 110 is not directly connected to the threshold inner panel 101, so that the installation position of the reinforcement 110 can be determined according to the welding point between the connection member 120 and the threshold inner panel 101, the installation position is more flexible, and the installation accuracy requirement is reduced, thereby improving assembly efficiency and reducing production costs.

[0053] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the connecting member 120 may include a plate body 121 , a first flanged edge 122 and a second flanged edge 123 .

[0054] The plate body 121 can be arranged on one side of the reinforcement 110 in the longitudinal direction of the vehicle, the first folded edge 122 can be connected to one end of the plate body 121 away from the rocker inner panel 101 and extend in the direction close to the reinforcement 110, the first folded edge 122 is connected to the side of the reinforcement 110 away from the rocker inner panel 101, the second folded edge 123 can be connected to one end of the plate body 121 close to the rocker inner panel 101 and extend in the direction away from the reinforcement 110, and the second folded edge 123 is connected to the side wall of the rocker inner panel 101.

[0055] In this embodiment, the connecting member 120 may be a sheet metal part, and the structural features of the plate body 121, the first flange 122, and the second flange 123 may be made by sheet metal processing, and the processing technology is simple and the cost is low. The connecting member 120 may be made of steel, which is convenient for sheet metal processing, and in the case that the current vehicle frame is generally made of steel, it is convenient to weld the connecting member 120 to the door sill inner plate 101, and the connection is simple and has high strength.

[0056] The first flanged edge 122 and the second flanged edge 123 can be bent and connected to the plate body 121, respectively. The first flanged edge 122 is provided at one end of the plate body 121 away from the rocker inner panel 101 and extends in a direction close to the reinforcement 110, so that the first flanged edge 122 can be connected to the side of the reinforcement 110 away from the rocker inner panel 101, and a force close to the rocker inner panel 101 is applied to the reinforcement 110. The second flanged edge 123 is provided at one end of the plate body 121 close to the rocker inner panel 101 and extends in a direction away from the reinforcement 110, so that when the connecting member 120 is welded to the rocker inner panel 101, the welding operation of the second flanged edge 123 and the rocker inner panel 101 is facilitated, and the second flanged edge 123 is welded to the side wall of the rocker inner panel 101, so that in the case of a side frontal collision of the vehicle, the connection structure between the reinforcement 110 and the rocker inner panel 101 is relatively stable and not easy to be disengaged.

[0057] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, the first flange 122 can be screwed to the reinforcement member 110 .

[0058] In this embodiment, when the reinforcement 110 is an aluminum profile and the connection member 120 is a steel material, welding is used to connect the reinforcement 110, which has high process requirements and high costs. By bolting the first flange 122 to the reinforcement 110, the connection strength is sufficient, the processing and assembly are simple, and the cost is low. The first flange 122 can be fixedly connected to the reinforcement 110 by multiple bolts, and the specific number of bolts is not limited here. For example, the first flange 122 is fixedly connected to the reinforcement 110 by two bolts.

[0059] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, the connecting member 120 may further include a third folded edge 124 , and the third folded edge 124 may be bent and connected to the upper end of the plate body 121 , and the third folded edge 124 may extend in the longitudinal direction of the vehicle.

[0060] In this embodiment, the third folded edge 124 can be bent and connected to the upper end of the plate body 121 and is made by sheet metal processing. The third folded edge 124 can extend along the longitudinal direction of the vehicle, which can improve the bending resistance of the connecting member 120.

[0061] In one example, the third folded edge 124 can be spaced apart from the sill inner panel 101 to improve the bending resistance of the connecting member 120 . In order to reduce the impact on the assembly connection between the connecting member 120 and the reinforcement 110 , the third folded edge 124 can extend in a direction away from the reinforcement 110 .

[0062] In another example, the third folded edge 124 can be welded to the top wall of the rocker inner panel 101 to improve the overall connection strength. In order to facilitate the connection between the connecting member 120 and the rocker inner panel 101, the third folded edge 124 can extend in a direction away from the reinforcement 110.

[0063] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, two connecting members 120 may be provided, and at least one of the two connecting members 120 further includes a fourth folded edge 125 , which is connected to the lower end of the plate body 121 by a bend, and the fourth folded edge 125 is connected to the bottom wall of the threshold inner panel 101 .

[0064] In this embodiment, two connecting members 120 may be provided to respectively fix the two ends of the reinforcement member 110 in the longitudinal direction of the vehicle. At least one of the two connecting members 120 is provided with a fourth folding edge 125, and the fourth folding edge 125 is bent and connected to the lower end of the plate body 121 to be connected to the bottom wall of the rocker inner panel 101, thereby improving the stability of the connection structure between the reinforcement member 110 and the rocker inner panel 101, and improving the structural strength of the lower side of the rocker inner panel 101. In the event of a side collision of the vehicle, the lower side of the rocker inner panel 101 is not easily deformed and turned inward, thereby reducing the damage caused to the occupants.

[0065] For example, in Figure 2 In the embodiment, the connecting member 120 near the rear side of the vehicle of the two connecting members 120 is provided with a fourth flanged edge 125. In other examples, the fourth flanged edge 125 may be provided at the connecting member 120 near the front side of the vehicle, or both connecting members 120 are provided with a fourth flanged edge 125 to further improve the connection strength.

[0066] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, a positioning hole 121a may be provided on the main board body.

[0067] When assembling the reinforcement 110, the connecting member 120 and the threshold inner panel 101, the reinforcement 110 and the connecting member 120 are first connected to form a whole, and then the reinforcement 110 and the connecting member 120 are welded together and connected to the threshold inner panel 101 through welding tools. In order to accurately determine the position of the reinforcement 110 and facilitate the operation of the tooling, a positioning hole 121a can be provided on the main body to facilitate the tooling to position the connecting member 120 and then position the reinforcement 110.

[0068] In this embodiment, in order to improve the accuracy of positioning, a plurality of positioning holes 121a may be provided, and the apertures of the plurality of positioning holes 121a may be set differently. Figure 2 and Figure 3 In the embodiment, two positioning holes 121 a are provided, and the apertures of the two positioning holes 121 a are different.

[0069] According to some embodiments of the present application, Figure 1-Figure 3 and Figure 5 As shown, the connecting piece and the rocker inner panel can be connected by welding.

[0070] In this embodiment, the connecting member 120 is welded to the threshold inner panel 101. Since the side wall of the threshold inner panel 101 is relatively flat, there are many positions for welding and they are easy to adjust. By adjusting the welding points of the connecting member 120 and the threshold inner panel 101, the relative position of the reinforcement 110 on the threshold inner panel 101 can be adjusted. The installation position is flexible. Compared with the related art of fixing the reinforcement 110 to the threshold inner panel 101 with bolts, the manufacturing and assembly precision requirements are lower, the process difficulty is reduced, the assembly efficiency can be improved and the production cost can be reduced.

[0071] According to some embodiments of the present application, Figure 4 As shown, the plurality of crush chambers 111 may form multiple layers in the vertical direction of the vehicle, and each layer may be provided with at least two crush chambers 111 .

[0072] It can be understood that the crush chambers 111 of each layer are distributed along the lateral direction of the vehicle. By arranging the crush chambers 111 in an upward direction of the vehicle and providing at least two crush chambers 111 on each layer, the structural strength of the reinforcement 110 is improved. The crush chambers 111 on the side close to the sill inner panel 101 are used to strengthen the structural strength of the sill inner panel 101, and the crush chambers 111 on the side away from the sill inner panel 101 are used for crushing energy absorption, thereby improving the overall safety performance.

[0073] According to some embodiments of the present application, Figure 4As shown, at least one layer of the multi-layer crush chamber 111 may be provided with three crush chambers 111 distributed in the transverse direction of the vehicle, and the width of the crush chamber 111 located in the middle position in the transverse direction of the vehicle is smaller than the width of the crush chambers 111 on both sides thereof in the transverse direction of the vehicle.

[0074] In this embodiment, at least one layer of the multi-layered crush chamber 111 may be provided with three crush chambers 111 distributed in the transverse direction of the vehicle, so as to improve the energy absorption effect and bending resistance of the vehicle when it receives a transverse collision. Among the crush chambers 111 located on both sides, the crush chamber 111 close to the rocker inner plate 101 mainly plays the role of strengthening the strength of the rocker inner plate 101, so the strength requirement is relatively high and the width is relatively large. In the event of a transverse collision, the crush chamber 111 close to the rocker outer plate is impacted first, so the crush chamber 111 mainly plays the role of crushing and absorbing energy, and has relatively high requirements for structural strength and energy absorption space. The crush chamber 111 located in the middle plays the role of supporting and absorbing energy, and has relatively low requirements for structural strength and width. The width of the crush chamber 111 in the middle position in the transverse direction of the vehicle is reduced, so as to increase the width of the crush chambers 111 located on both sides thereof in a limited space, and optimize the spatial layout.

[0075] According to some embodiments of the present application, Figure 4 As shown, the collapse chamber 111 at the uppermost layer among the multi-layer collapse chambers 111 and located on the side close to the rocker outer plate is the first collapse chamber 111a, and the top wall of the first collapse chamber 111a is inclined downward in the direction close to the rocker outer plate.

[0076] In this embodiment, in order to adapt to the design of the rocker outer panel, the top wall of the first collapse chamber 111a is tilted downward in the direction close to the rocker outer panel to avoid the rocker outer panel, wherein the reinforcement 110 is spaced apart from the rocker outer panel for easy assembly, and a collapse space is reserved between the rocker outer panel and the reinforcement 110.

[0077] It is understandable that the number of layers of the crush chamber 111 and the number of crush chambers 111 in each layer are not limited herein, and are determined based on actual design conditions. The aspect ratio of the crush chamber 111 needs to be comprehensively considered so that the crush chamber 111 has sufficient structural strength and energy absorption effect.

[0078] In some embodiments, Figure 4 As shown, the crush chambers 111 are provided with three layers in the vertical direction of the vehicle, the top layer is provided with two crush chambers 111, and the middle layer and the lower layer are respectively provided with three crush chambers 111. Among them, the height of the two crush chambers 111 located at the top layer is less than the height of the crush chambers 111 at the middle layer and the lower layer, so as to adapt to the structural shape of the rocker outer plate. Therefore, in order to ensure that the crush chambers 111 at the top layer have sufficient structural strength and crushing space, the number of the crush chambers 111 at the top layer is less than the number of the crush chambers 111 at the middle layer and the lower layer.

[0079] The present application also provides a vehicle, including:

[0080] like Figure 1 and Figure 5 As shown, the vehicle includes a rocker beam assembly 100 , a seat front cross beam 200 and a seat rear cross beam 300 .

[0081] The threshold beam assembly 100 is a threshold beam assembly 100 as in any of the above-mentioned technical solutions, including the technical features and technical effects of the threshold beam assembly 100 as in any of the above-mentioned technical solutions, which will not be elaborated herein.

[0082] It can be understood that two sill beam assemblies 100 may be provided, and the two sill beam assemblies 100 are respectively arranged on both sides in the lateral direction of the vehicle.

[0083] The front cross beam 200 and the rear cross beam 300 are distributed along the longitudinal direction of the vehicle, one end of the front cross beam 200 and the rear cross beam 300 in the transverse direction is connected to the connecting surface, and the reinforcement 110 corresponds to the front cross beam 200 and the rear cross beam 300 in the transverse direction of the vehicle.

[0084] In this embodiment, the front seat beam 200 and the rear seat beam 300 extend in the transverse direction, and one end of the front seat beam 200 and the rear seat beam 300 in the transverse direction is connected to the connecting surface of the rocker inner panel 101 .

[0085] The vehicle also includes a battery pack, which is arranged on the inner side of the sill beam assembly 100 and is located on the lower side of the front seat beam 200 and the rear seat beam 300. The reinforcement 110 corresponds to the front seat beam 200 and the rear seat beam 300 in the lateral direction of the vehicle to strengthen the structural strength of the connection between the sill beam and the front seat beam 200 and the rear seat beam 300, improve the stability of the force transmission path, and in the event of a side collision of the vehicle, the sill beam assembly 100 is not easy to collapse and squeeze the battery pack, thereby improving the safety factor of the vehicle. The structure is simple and the production cost is reduced.

[0086] In some embodiments, Figure 5 As shown, the distance L1 between the ends of the front seat beam 200 and the rear seat beam 300 that face away from each other in the longitudinal direction of the vehicle, and the length L2 of the reinforcement 110 in the longitudinal direction of the vehicle satisfy L1≤L2, so that the first reinforcement 110 can completely cover the connection between the front seat beam 200 and the rear seat beam 300 and the door sill beam in the transverse direction of the vehicle, reduce the influence of assembly errors, and improve the structural strength.

[0087] In some embodiments, the distance L1 between the ends of the front seat beam 200 and the rear seat beam 300 that face away from each other in the longitudinal direction of the vehicle, and the length L2 of the reinforcement 110 in the longitudinal direction of the vehicle satisfy: 20 mm ≤ L2 - L1 ≤ 100 mm.

[0088] Among them, the value range of L2-L1 is [20mm-100mm]. Specifically, L2-L1 can be 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm or other values ​​between 20mm and 100mm.
