[0002] With the rapid development of the new energy vehicle market, how to ensure the safety of high-voltage batteries and drivers and passengers in different collision situations of new energy vehicles, especially in side collision situations, has become the focus of new energy vehicle research and development. New energy and hybrid vehicles usually place high-voltage batteries under the body floor. In side collisions, especially side column collisions, new energy vehicles have less crushing space, shorter force transmission paths, or even missing or interrupted force transmission, which makes it difficult to effectively transmit force in side collisions. High-voltage batteries and internal modules are easily squeezed and leak, thermal runaway and other adverse conditions occur, which easily lead to battery pack damage and safety accidents. Existing new energy vehicles use a crossbeam in the body floor to strengthen the body structure and prevent excessive deformation of the body in a side collision. However, the existing crossbeam structure connection and assembly process are relatively complicated, resulting in low production efficiency and high cost; at the same time, the crossbeam is generally welded in the form of roll-pressed steel as the main structure of the crossbeam, which further increases the weight of the body; in addition, the internal reinforcement structure of the crossbeam lacks effective connection with the surrounding environment structure, which leads to a low contribution of the crossbeam to the body stiffness.

[0027] Please also see Figure 1 and Figure 2 An embodiment of the utility model provides a crossbeam frame 100 , at least one outer side wall of the crossbeam frame 100 is protrudingly provided with a reinforcing rib 110 ; the reinforcing rib 110 is arranged on at least one outer side wall of the crossbeam frame 100 along the length direction of the crossbeam frame 100 .

[0028] In this embodiment, a reinforcing rib 110 with a certain protruding distance is protrudingly provided on the outer side wall of the cross beam skeleton 100. The number of the reinforcing rib 110 can be one or more, and the thickness of the reinforcing rib 110 can be set according to actual needs. Each reinforcing rib 110 is a structure integrally formed with the cross beam skeleton 100, and the extending direction of the reinforcing rib 110 is to extend along the length direction of the cross beam skeleton 100. When the vehicle body is subjected to a side collision and the cross beam skeleton 100 is subjected to force along the length direction, the reinforcing rib 110 makes the cross beam skeleton 100 gradually collapse while reducing the shearing effect, preventing the cross beam skeleton 100 from excessive bending, thereby further enhancing the overall rigidity of the cross beam skeleton 100. Moreover, in order to facilitate the connection of the cross beam skeleton 100 with other structures, the reinforcing rib 110 and the outer side wall of the cross beam skeleton 100 can also be enclosed to form a connector fixing groove 120 for fixing the connector.

[0029] In one embodiment, if Figure 1 and Figure 2 As shown, a hollow cavity 130 is opened inside the crossbeam skeleton 100 ; the hollow cavity 130 runs through both ends of the crossbeam skeleton 100 .

[0030] In this embodiment, the interior of the beam skeleton 100 is a hollow structure, and the hollow cavity 130 is arranged inside the beam skeleton 100 along the length direction of the beam skeleton 100 and connects the two ends of the beam skeleton 100. Furthermore, when the beam skeleton 100 is painted and baked, the hollow cavity 130 can allow air to circulate inside the beam skeleton 100 to achieve effective heat exchange. At the same time, the hollow cavity 130 can also allow electrophoresis liquid to flow through, so that the entire beam skeleton 100 can be evenly soaked in the electrophoresis liquid.

[0031] In one embodiment, if Figure 2 As shown, support ribs 140 are provided in the hollow cavity 130 ; the support ribs 140 are fixedly provided inside the hollow cavity 130 along the length direction of the crossbeam skeleton 100 ; the support ribs 140 divide the hollow cavity 130 into a first hollow cavity 131 and a second hollow cavity 132 .

[0032] In this embodiment, the support rib 140 is a structure disposed inside the hollow cavity 130 and formed integrally with the cross beam skeleton 100. The two ends of the support rib 140 are respectively connected to the inner side of the first side wall 101 connected to the sheet metal profile in the cross beam skeleton 100 and the inner side of the second side wall 102 opposite to the first side wall 101, and the hollow cavity 130 is divided into a first hollow cavity 131 and a second hollow cavity 132. The support rib 140 can effectively ensure the overall rigidity of the cross beam skeleton 100 while the hollow cavity 130 exists.

[0033] Please also see Figure 3 and Figure 4 The embodiment of the utility model also provides a floor beam 10, including a beam frame 100, a connecting piece 200 and a sheet metal profile 300; the connecting piece 200 is fixedly arranged on at least one outer side wall of the beam frame 100 along the length direction of the beam frame 100; the central axis of the connecting piece 200 is parallel to the central axis of the beam frame 100; the lower part of the connecting piece 200 provided in the beam frame 100 is connected to the floor.

[0034] In this embodiment, the cross beam skeleton 100 is a rigid structure with a certain length, specifically a glass fiber cross beam structure integrally formed by continuous pultrusion process. The cross beam skeleton 100 processed in this way has a lightweight structure, which can significantly reduce the overall weight of the vehicle body. The sheet metal profile 300 is a rigid structure with a certain length, and its cross section is set to be U-shaped to form an overall groove structure. At the same time, the cross beam skeleton 100 can be set to a structure with a quadrilateral cross section. Furthermore, the cross beam skeleton 100 can be accommodated as a whole into the groove formed by the sheet metal profile 300, and the central axis of the cross beam skeleton 100 is parallel to the central axis of the sheet metal profile 300. Each outer side wall of the cross beam skeleton 100 is a plane, and the cross beam skeleton 100 can be fitted on the bottom end face of the groove structure of the sheet metal profile 300. Specifically, the cross beam skeleton 100 and the sheet metal profile 300 can be pre-fixed by screwing, riveting, etc., and then installed as a whole at the position where the lateral rigidity needs to be strengthened in the vehicle body. The connector 200 is a foamable structure such as a heat-expandable structural adhesive that is pre-filled or pasted on the outer wall of the cross beam frame 100. Specifically, the connector 200 is first arranged on one end face of the cross beam frame 100 that is bonded and connected to the sheet metal profile 300, and the shape of the connector 200 after pasting or filling is also a shape with a certain length extending along the length direction of the cross beam frame 100. When the floor cross beam 10 is subsequently painted and baked, the increase in temperature will cause the connector 200 to foam, and then the volume of the connector 200 will increase and fill the gap between the cross beam frame 100 and the sheet metal profile 300. At the same time, after the connector 200 is foamed and cooled, it will be transformed from a soft structure before foaming to a rigid structure. Then, the connector 200 can work together with the cross beam frame 100 to strengthen the vehicle body strength and effectively ensure the safety of passengers when a collision occurs.

[0035] In one embodiment, if Figure 3 As shown, the reinforcing rib 110 includes a first reinforcing rib 111 and a second reinforcing rib 112 ; the first reinforcing rib 111 , the second reinforcing rib 112 and the outer side wall of the crossbeam skeleton 100 together form a connecting member fixing groove 120 ; the connecting member 200 is disposed in the connecting member fixing groove 120 .

[0036] In this embodiment, the first reinforcing rib 111 and the second reinforcing rib 112 are arranged on the same outer side wall of the cross beam skeleton 100, and the first reinforcing rib 111 and the second reinforcing rib 112 are parallel to each other and have a certain distance. Furthermore, the space between the first reinforcing rib 111 and the second reinforcing rib 112 forms a connector fixing groove 120, and the connector 200 can be filled or pasted in the connector fixing groove 120. Since the extension direction of the connector fixing groove 120 also extends along the length direction of the cross beam skeleton 100, after the connector 200 is filled or pasted into the connector fixing groove 120, it can be distributed along the length direction of the cross beam skeleton 100. Furthermore, the connector 200 can be confined to a fixed area for foaming, and the rigid structure formed after foaming can also be evenly distributed along the cross beam skeleton 100, uniformly improving the overall rigidity.

[0037] In one embodiment, if Figure 3 and Figure 4 As shown, the crossbeam skeleton 100 includes a first side wall 101 facing the sheet metal profile 300, a second side wall 102 opposite to the first side wall 101, a third side wall 103 adjacent to the first end of the first side wall 101 and the first end of the second side wall 102, and a fourth side wall 104 adjacent to the second end of the first side wall 101 and the second end of the second side wall 102; the vertical distance between the end of the third side wall 103 connected to the second side wall 102 and the first side wall 101 is greater than the vertical distance between the end of the fourth side wall 104 connected to the second side wall 102 and the first side wall 101.

[0038] In this embodiment, the cross section of the cross beam skeleton 100 is set to be a quadrilateral, wherein the first side wall 101 is the end face where the cross beam skeleton 100 is connected to the sheet metal profile 300, the third side wall 103 and the fourth side wall 104 are end faces perpendicular to the first side wall 101, and the second side wall 102 is an end face opposite to the first side wall 101. The third side wall 103 and the fourth side wall 104 extend from the first side wall 101 to a certain vertical height respectively, and the vertical height of the third side wall 103 extending from the first side wall 101 is greater than the vertical height of the fourth side wall 104 extending from the first side wall 101. Furthermore, a certain angle is formed between the second side wall 102 and the first side wall 101, and the second side wall 102 is in an inclined state. At the same time, the third side wall 103 and the fourth side wall 104 are both perpendicular to the first side wall 101, and thus the cross section of the cross beam skeleton 100 presents a right-angle trapezoid. This type of arrangement can achieve a progressive collapse effect on the crossbeam frame 100 when the vehicle body is hit from the side, thereby improving passenger safety.

[0039] In one embodiment, if Figure 3 and Figure 4 As shown, the connecting member 200 is fixedly disposed on the outer wall of the first side wall 101 of the cross beam skeleton 100 facing the sheet metal profile 300 and the outer wall of the second side wall 102 of the cross beam skeleton 100 opposite to the first side wall 101 .

[0040] In this embodiment, the connecting member 200 is arranged on the first side wall 101 and the second side wall 102. When the cross beam of the vehicle 20 is installed inside the vehicle body, the connecting member 200 located on the second side wall 102 can fill the gap between the cross beam frame 100 and the vehicle body structure after foaming, while the connecting member 200 located on the first side wall 101 can fill the gap between the sheet metal profile 300 and the cross beam frame 100, thereby enhancing the stiffness at two locations.

[0041] In one embodiment, if Figure 3 and Figure 4 As shown, the connecting member 200 includes a first connecting member 201, a second connecting member 202, a third connecting member 203 and a fourth connecting member 204; the first connecting member 201 and the second connecting member 202 are arranged on the outer wall of the first side wall 101 of the crossbeam skeleton 100 facing the sheet metal profile 300; the third connecting member 203 and the fourth connecting member 204 are arranged on the outer wall of the second side wall 102 of the crossbeam skeleton 100 opposite to the first side wall 101.

[0042] In this embodiment, the first connecting member 201 and the second connecting member 202 are both arranged on the outer wall of the first side wall 101 in the cross beam frame 100, and the third connecting member 203 and the fourth connecting member 204 are both arranged on the outer wall of the second side wall 102 in the cross beam frame 100. After the first connecting member 201 and the second connecting member 202 are foamed, they can provide rigidity support from two positions on the first side wall 101, and after the third connecting member 203 and the fourth connecting member 204 are foamed, they can also provide rigidity support at two positions on the second side wall 102, so as to realize a three-dimensional rigidity support system.

[0043] In one embodiment, if Figure 3 and Figure 4 As shown, the first connecting member 201 and the second connecting member 202 are respectively disposed at the two end edges of the first side wall 101 ; the third connecting member 203 and the fourth connecting member 204 are respectively disposed at the two end edges of the second side wall 102 .

[0044] In this embodiment, the first connecting member 201 and the second connecting member 202 are respectively arranged at the two end edges of the first side wall 101, and the third connecting member 203 and the fourth connecting member 204 are respectively arranged at the two end edges of the second side wall 102. Furthermore, after each connecting member 200 is foamed, there is a certain distance between the foaming position of the first connecting member 201 and the foaming position of the second connecting member 202, and there is also a certain distance between the foaming position of the third connecting member 203 and the foaming position of the fourth connecting member 204, thereby being able to provide more uniform rigidity support.

[0045] See also Figure 5 , Figure 5 A schematic diagram of a partial structure of a vehicle provided in an embodiment of the utility model, such as Figure 5 As shown, the embodiment of the utility model also provides a vehicle 20, including a floor beam as described in any of the above embodiments, and also including a floor body 21; the sheet metal profile 300 in the floor beam is fixedly connected to the floor body 21; the beam frame 100 and the connecting member 200 in the floor beam are located between the sheet metal profile 300 and the floor body 21.

[0046] In this embodiment, if Figure 5 The local structure of the vehicle 20 shown is a structural member installed at the bottom of the vehicle body in a new energy vehicle, which bears the weight of other components inside the vehicle body. The floor body 21 is the main structure of the vehicle 20, and the floor beam is installed on the floor body 21 in a direction parallel to the lateral axis of the floor body 21. Furthermore, when the vehicle body is hit from the side, the floor beam can collapse along the length direction. During the specific installation, the sheet metal profile 300 is turned upside down so that the beam frame 100 faces the floor body 21, and then the sheet metal profile 300 is connected to the floor body 21 to fix the beam frame 100 and the connecting member 200 between the sheet metal profile 300 and the floor body 21. Through this arrangement, the beam frame 100, the connecting member 200 and the floor body 21 can be effectively and firmly connected, thereby achieving high rigidity and high safety of the overall structure.

[0047] Based on the above structure and its connection mode, the floor cross beam provided by the embodiment of the utility model has a combined structure of a cross beam frame and a connecting piece, and the cross beam frame provides overall rigidity while the connecting piece further improves the overall rigidity of the floor cross beam, thereby ensuring the overall safety and reliability of the floor cross beam in the event of a collision. At the same time, the cross beam frame is pre-installed on the sheet metal profile, and then directly installed on the floor body of the vehicle, and the cross beam frame and the connecting piece are located between the sheet metal profile and the floor body, which simplifies the installation steps and improves the installation efficiency, and enables the floor cross beam to form an integral structure that is stably connected to the floor body through the sheet metal profile and the connecting piece, thereby improving the contribution of the floor cross beam to the overall rigidity of the vehicle body.
