[0038] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0039] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0041] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0042] In the drawings herein, a first direction Y represents the transverse direction of the rear frame (the direction from the side of the vehicle to the other side of the vehicle), a second direction X represents the longitudinal direction of the rear frame (the direction from the rear of the vehicle to the front of the vehicle), and a third direction Z represents the height direction of the rear frame (the direction from the bottom of the vehicle to the top of the vehicle). Directions X, Y, and Z are perpendicular to each other.

[0043] In a first aspect, an embodiment of the present application provides a crossbeam of a rear frame. The crossbeam is one of the components of the rear frame. The crossbeam is used to provide the required structural strength for the rear frame. The crossbeam can also serve as a mounting structure for other vehicle parts.

[0044] Please refer to Figure 1-Figure 2 As shown, the crossbeam 1 includes an integrally formed crossbeam body 11 and a center channel connector 12, which is used to connect to the vehicle's center channel. The center channel (also known as the center console) is located between the driver's seat and the passenger seat and is used to install control buttons, joysticks, connection ports, and storage boxes.

[0045] In the prior art, the crossbeam and the middle channel connector are separately arranged. The crossbeam is first connected to the middle channel connector, and the middle channel connector is then connected to the middle channel. There are welding parts in the connection structure between the crossbeam and the middle channel connector. The stress concentration degree of the welding parts is relatively large. The connection structure between the crossbeam and the middle channel connector is prone to structural problems such as deformation or cracking. Therefore, the structural stability of the connection structure between the crossbeam and the middle channel connector is relatively poor. Secondly, this connection structure requires more parts, more manufacturing process flows, greater manufacturing process difficulty, and a longer manufacturing cycle.

[0046] Compared to the prior art, the crossbeam 1 connected to the central channel in this embodiment is an integrally formed structural component. There are no welds within the crossbeam 1, resulting in less stress concentration within the crossbeam 1 and less prone to structural problems such as deformation or cracking. Consequently, the internal structure of the crossbeam 1 is highly stable. The integrally formed crossbeam 1 requires fewer parts, has fewer manufacturing processes, is less complex, and has a shorter manufacturing cycle.

[0047] Please refer to Figure 2 As shown, the crossbeam 1 also includes a first reinforcing rib 13, which extends from the crossbeam body 11 to the central channel connection portion 12. The crossbeam body 11 extends in a first direction Y, and the central channel connection portion 12 is disposed on the side of the crossbeam body 11 in a second direction X. With this arrangement, the connection structure between the crossbeam body 11 and the central channel connection portion 12 is structurally strong, and the likelihood of structural problems such as deformation or cracking in the connection structure between the crossbeam body 11 and the central channel connection portion 12 is low.

[0048] The middle portion of the beam body 11 in the first direction Y and the middle channel connecting portion 12 are integrally formed.

[0049] In addition, the cross-sectional shape of the first reinforcing rib 13 can be an arc shape such as a U-shape or a C-shape.

[0050] Furthermore, the middle channel connecting portion 12 protrudes along the second direction X relative to the beam body 11 .

[0051] Since the height of the middle channel is higher than that of the beam 1, please refer to Figure 1-Figure 2 As shown, at least part of the structure of the middle channel connecting portion 12 is tilted relative to the crossbeam body 11, allowing it to connect to the taller middle channel. Accordingly, the first reinforcing rib 13 includes a first section 131 and a second section 132, which are connected. The first section 131 is located in the crossbeam body 11, and the second section 132 is located in the middle channel connecting portion 12. The extension direction of the second section 132 intersects the extension direction of the first section 131. Because the first reinforcing rib 13 includes two first sections 131 and second sections 132 extending in different directions, the bending section modulus of the crossbeam 1 perpendicular to the extension direction of the first section 131 and the bending section modulus of the crossbeam 1 perpendicular to the extension direction of the second section 132 are both high, providing the crossbeam 1 with greater bending strength.

[0052] Among them, in a side view (along the first direction Y), the extension direction of the second segment 132 intersects with the extension direction of the first segment 131, and in a top view (along the opposite direction of the third direction Z) or in an upward view (along the third direction Z), the extension direction of the second segment 132 and the extension direction of the first segment 131 are both parallel to the second direction X.

[0053] Optionally, the middle channel connection portion 12 includes an integrally formed first connection portion 121 and a second connection portion 122, wherein the first connection portion 121 is integrally formed with the crossbeam body 11, the second section 132 is located on the first connection portion 121, and the second connection portion 122 is located on a side of the first connection portion 121 facing away from the crossbeam body 11. The first connection portion 121 is inclined relative to the crossbeam body 11, and the second connection portion 122 is inclined relative to the first connection portion 121. The arrangement of the second connection portion 122 being inclined relative to the first connection portion 121 makes the structure of the middle channel connection portion 12 a bent structure, the middle channel connection portion 12 has a high bending section modulus, and the middle channel connection portion 12 has a high bending structural strength. Accordingly, the structural stability of the connection structure including the middle channel connection 12 is relatively high.

[0054] Optionally, the crossbeam 1 further includes a second reinforcing rib 14 , which is located at the second connecting portion 122 . The second reinforcing rib 14 is connected to the second section 132 and is offset in the first direction Y. With this arrangement, the structural strength of the middle channel connecting portion 12 is increased, and the structural stability of the connecting structure including the middle channel connecting portion 12 is increased.

[0055] The cross-sectional shape of the second reinforcing rib 14 can be an arc shape such as a U-shape or a C-shape.

[0056] In addition, the extending direction of the second reinforcing rib 14 is parallel to the second direction X in a top view or a bottom view.

[0057] Furthermore, when viewed from the side, the extension direction of the second reinforcement rib 14 intersects with the extension direction of the second section 132. The bending section coefficient of the cross section of the middle channel connection part 12 perpendicular to the extension direction of the second section 132 and the bending section coefficient of the cross section perpendicular to the extension direction of the second reinforcement rib 14 are both high, so that the middle channel connection part 12 has better bending structural strength.

[0058] In addition, the protruding direction of the first reinforcing rib 13 can be from the bottom surface of the beam 1 to the top surface of the beam 1, and the protruding direction of the second reinforcing rib 14 can be from the top surface of the beam 1 to the bottom surface of the beam 1, that is, the protruding direction of the first reinforcing rib 13 and the protruding direction of the second reinforcing rib 14 are opposite. Under this setting, the bending section coefficient of the beam 1 is higher, and the bending structural strength of the beam 1 is greater. Correspondingly, the stability of the connection structure including the beam 1 is greater.

[0059] In other embodiments (not shown in the figures), the protruding direction of the first reinforcing rib 13 can be from the top surface of the beam 1 to the bottom surface of the beam 1, and the protruding direction of the second reinforcing rib 14 can be from the bottom surface of the beam 1 to the top surface of the beam 1.

[0060] The misalignment described herein means that two different features do not completely overlap in a set direction, that is, they may partially intersect or be spaced apart.

[0061] Optionally, the number of first reinforcing ribs 13 is two, or in other words, the number of second sections 132 is two, and the number of second reinforcing ribs 14 is two, wherein one first reinforcing rib 13, two second sections 132 and another first reinforcing rib 13 are staggered in the first direction Y. This arrangement is beneficial to further improve the structural strength of the middle channel connection part 12.

[0062] In other embodiments (not shown in the figures), the number of the first reinforcing ribs 13 may also be three or more, and correspondingly, the number of the second reinforcing ribs 14 may also be three or more.

[0063] Optionally, the beam 1 also includes a third reinforcing rib 15, which is staggered with the first reinforcing rib 13 in the first direction Y, and the third reinforcing rib 15 extends from the two side portions of the middle channel connecting portion 12 that are relatively arranged in the first direction Y to the beam body 11. This arrangement is beneficial to further improving the structural strength of the internal structure of the beam 1.

[0064] The cross-sectional shape of the third reinforcing rib 15 may be L-shaped, V-shaped or other shapes similar to a step structure.

[0065] Optionally, the third reinforcing rib 15 includes a third section 151 and a fourth section 152 connected to each other. The third section 151 is located in the crossbeam body 11, and the fourth section 152 is located in the central channel connecting portion 12. The extension direction of the third section 151 intersects the extension direction of the fourth section 152. With this arrangement, the structural strength of the connection structure between the crossbeam body 11 and the central channel connecting portion 12 is greater, and the possibility of structural problems such as deformation or cracking in the connection structure between the crossbeam body 11 and the central channel connecting portion 12 is reduced.

[0066] The fourth section 152 may be located in the second section 132 of the middle channel connecting portion 12 .

[0067] In addition, when looking down or looking up, the extension direction of the third section 151 intersects with the extension direction of the fourth section 152, and when looking from the side, the extension direction of the third section 151 intersects with the extension direction of the fourth section 152. This arrangement makes the bending section coefficient of the cross section of the beam 1 perpendicular to the extension direction of the third section 151 and the bending section coefficient of the cross section perpendicular to the extension direction of the fourth section 152 both higher, so that the beam 1 has better bending structural strength.

[0068] Optionally, the crossbeam body 11 includes a first flange 111, the middle channel connection portion 12 includes a second flange 123, and a first notch 16 is provided at the connection portion between the first flange 111 and the second flange 123. The first flange 111 is used to increase the bending cross-sectional modulus of the crossbeam body 11, thereby increasing the bending strength of the crossbeam body 11. The second flange 123 is used to increase the bending cross-sectional modulus of the middle channel connection portion 12, thereby increasing the bending strength of the middle channel connection portion 12. The first notch 16 is used to reduce stress concentration at the connection portion between the first flange 111 and the second flange 123, thereby reducing the possibility of cracking at the connection portion between the first flange 111 and the second flange 123.

[0069] Optionally, the cross-sectional shape of the beam body 11 is L-shaped, and the beam body 11 includes an integrally formed first body 112 and a second body 113, the second body 113 and the middle channel connecting portion 12 are integrally formed, and the connecting portion between the flange of the first body 112 and the flange of the second body 113 is provided with a second notch 114, and the second notch 114 is used to reduce the stress concentration degree of the connecting portion between the flange of the first body 112 and the flange of the second body 113, thereby reducing the possibility of cracking problems in the connecting portion between the flange of the first body 112 and the flange of the second body 113.

[0070] Optionally, a third notch 122 a is provided at the edge of the second connection portion 122 , and the third notch 122 a is used to reduce stress concentration at the edge of the second connection portion 122 , thereby reducing the possibility of cracking of the second connection portion 122 .

[0071] Optionally, since the first reinforcing rib 13, the second reinforcing rib 14 and the third reinforcing rib 15 are all formed by stamping and bending a plate structural member, the groove formed by bending any one of the first reinforcing rib 13, the second reinforcing rib 14 and the third reinforcing rib 15 can be used to arrange the pipelines required for the vehicle. This arrangement is conducive to improving the structural compactness of the vehicle, and the saved space can be used to arrange other new vehicle parts to enable the vehicle to have more new functions.

[0072] The size of the middle channel connecting portion 12 can be set according to the size of the middle channel to be connected. When the size of the middle channel connecting portion 12 is increased, the structural strength of the middle channel connecting portion 12 and the structural strength of the crossbeam 1 are also increased. Secondly, the connection area between the middle channel connecting portion 12 and the middle channel is also increased, and the connection reliability of the connection structure between the middle channel connecting portion 12 and the middle channel is higher.
