[0052] Specifically, the vehicle includes a sliding center door, which can slide along the guide rail on the vehicle rocker to open or close the vehicle door. Among them, the guide rail generally includes an upper guide rail and a lower guide rail, and the lower guide rail is used to support the center door, and there is often a problem that the lower guide rail is easy to deform and fall off the rocker, which reduces the structural stability of the vehicle.

[0053] To solve the above problems, the present application provides a rocker 1 for a vehicle, such as Figures 1-4As shown, the threshold 1 comprises a threshold plate assembly 11, a lower guide rail 12 and a support 13, the lower guide rail 12 comprises an upper shell 121 and a lower shell 122, the upper shell 121 is fixedly connected with the lower shell 122, and there is a support space 14 between the lower shell 122 and the threshold plate assembly 11 in the height direction of the threshold 1. The support 13 is located in the support space 14 and is connected with the lower shell 122 and the threshold plate assembly 11, and the support 13 is used for supporting the lower shell 122.

[0054] When the support 13 is located between the lower shell 122 and the threshold plate assembly 11, the support 13 is used for supporting the lower shell 122 in the height direction of the threshold 1, so as to reduce the risk of deformation of the lower shell 122 caused by the impact force of the threshold 1, thereby facilitating to improve the structural strength of the lower shell 122, thereby facilitating to reduce the risk of deformation of the threshold 1, thereby facilitating to improve the structural strength of the threshold 1.

[0055] In a specific embodiment, the lower shell 122 and the threshold plate assembly 11 can be welded by the support 13 in the height direction of the threshold 1, which is conducive to reducing the risk of mutual separation of the lower shell 122 and the threshold plate assembly 11, and further improving the structural stability of the threshold 1.

[0058] In a possible implementation, as shown in Figure 2 and Figure 6 As shown, the support 13 comprises a body 131, a first abutting portion 132 and a second abutting portion 133, the first abutting portion 132 and the second abutting portion 133 extend outwardly in the length direction of the threshold 1, the first abutting portion 132 is connected with the lower shell 122 in the height direction of the threshold 1, and the second abutting portion 133 is connected with the threshold plate assembly 11.

[0059] In the embodiment, the first abutting portion 132 is welded to the side of the lower shell 122 away from the upper shell 121 along the height direction of the threshold 1, and the second abutting portion 133 is welded to the side of the threshold plate assembly 11 facing the lower shell 122. Therefore, the first abutting portion 132 and the second abutting portion 133 can improve the connection strength of the support 13 and the threshold plate assembly 11 of the lower shell 122, and when the threshold 1 is subjected to an impact force, such as in a collision process, the support 13 can reduce the risk of relative torsion and deformation of the lower shell 122 and the threshold plate assembly 11, thereby improving the structural stability of the lower shell 122 and the threshold plate assembly 11.

[0060] In a possible implementation, as shown in Figure 6 The support 13 further includes a third abutting portion 134 protruding from the body 131, the third abutting portion 134 extends in the same plane as the first abutting portion 132, and the extending directions of the two are different, and the third abutting portion 134 is used to connect with the lower shell 122.

[0061] In the embodiment, the third abutting portion 134 is welded to the side of the lower shell 122 away from the upper shell 121, so as to reduce the risk of relative offset of the lower shell 122 and the threshold plate assembly 11 along the width direction of the threshold 1, and further improve the connection strength and stability of the threshold plate assembly 11 and the lower shell 122.

[0062] In a possible implementation, as shown in Figure 6 The support 13 can include two first abutting portions 132, the two first abutting portions 132 are arranged in a spaced manner, and the extending directions of the two are opposite, and the third abutting portion 134 is located between the two first abutting portions 132, and the third abutting portion 134 can extend in a direction perpendicular to the extending direction of the first abutting portion 132.

[0063] In a possible implementation, as shown in Figure 6 In the embodiment, the support 13 has two first abutting portions 132 along the length direction of the threshold 1, and the extending directions of the two first abutting portions 132 are opposite, and the third abutting portion 134 is located between the two first abutting portions 132, and the third abutting portion 134 has a gap 136 between the first abutting portion 132.

[0064] In the embodiment, the support 13 further has two second abutting portions 133 along the length direction of the threshold 1, and the extending directions of the two second abutting portions 133 are opposite, and the support 13 has the two first abutting portions 132 and the two second abutting portions 133, so as to improve the support strength of the support 13 supporting the lower shell 122 and the stability of the connection with the lower shell 122. The third abutting portion 134 has a gap 136 between the first abutting portion 132, which is beneficial to reduce stress concentration and further improve the structural strength of the support 13.

[0065] In a possible implementation, as shown in Figure 6 The support 13 further comprises a connecting portion 135 connected with the body 131, the connecting portion 135 being used to connect the first abutting portion 132 and the second abutting portion 133, and the connecting portion 135 is inclined relative to the body 131 along the width direction of the rocker 1.

[0066] In this embodiment, the connecting portion 135 is inclined relative to the body 131 along the width direction of the rocker 1, compared with the connecting portion 135 being arranged perpendicularly relative to the body 131, which is beneficial to improve the convenience of installing the support 13 in the support space 14, and is convenient for production. Meanwhile, the connecting portion 135 can improve the deformation resistance of the first abutting portion 132 and the second abutting portion 133, thereby being beneficial to improve the structural strength of the support 13.

[0067] In a possible implementation, as shown in Figure 6 The body 131 and the connecting portion 135 form a U-shaped structure, that is, the cross-sectional shape of the support 13 is U-shaped, which is beneficial to improve the strength of the support bracket, further reduce the possibility of deformation, and improve the stability and reliability of the support 13 supporting the lower shell 122.

[0068] In a possible implementation, as shown in Figures 2-4 The rocker panel assembly 11 is in a stepped shape, and the lower shell 122 is overlapped on one side of the rocker panel assembly 11 facing the upper shell 121 along the height direction of the rocker 1 to form the support space 14.

[0069] In this embodiment, the rocker panel assembly 11 is in a stepped shape, so that after the lower shell 122 is overlapped with the rocker panel assembly 11, the two can have a gap along the height direction of the rocker 1, that is, the support space 14 can be formed between the lower shell 122 and the rocker panel assembly 11, which is beneficial to improve the feasibility of installing the support 13 in the support space 14.

[0070] In a possible implementation, as shown in Figure 1 The rocker 1 further comprises a B-pillar lower reinforcement plate 15, a B-pillar reinforcement plate 17, a C-pillar reinforcement plate 16, and a rocker beam assembly 19 used to connect the B-pillar reinforcement plate 17, the C-pillar reinforcement plate 16, and the B-pillar lower reinforcement plate 15, and the lower rail 12 and the rocker panel assembly 11 are connected with the B-pillar lower reinforcement plate 15 and the C-pillar reinforcement plate 16, so that the lower rail 12, the B-pillar lower reinforcement plate 15, the C-pillar reinforcement plate 16, the B-pillar reinforcement plate 17, and the rocker beam assembly 19 form a closed structure.

[0071] Specifically, the B-pillar lower reinforcement plate 15 is configured to improve the crashworthiness of the B-pillar of the vehicle, and the C-pillar reinforcement plate 16 is configured to improve the crashworthiness of the C-pillar of the vehicle. In this embodiment, when the vehicle is subjected to a collision (e.g., a frontal impact), the impact force can be transmitted from the front end of the vehicle body to the lower rail 12 and the rocker panel assembly 11, and then to the B-pillar lower reinforcement plate 15, the C-pillar reinforcement plate 16, and the B-pillar reinforcement plate 17, and then transmitted and dispersed to the entire vehicle (i.e., the transmission path of the impact force F shown by the arrow in the figure), which is beneficial to improve the transmission path of the impact force, reduce stress concentration, and thus reduce the risk of deformation of the lower rail 12, thereby reducing the risk of deformation of the rocker 1 and improving the safety of the rocker 1. Figure 1

[0072] In a possible implementation, as shown in the figure, Figure 4 the lower rail 12 includes a first welding end 124 and a second welding end 125 along the length direction of the rocker 1, the first welding end 124 is welded to the B-pillar lower reinforcement plate 15, and the second welding end 125 is welded to the C-pillar reinforcement plate 16.

[0073] In this embodiment, the B-pillar lower reinforcement plate 15 and the C-pillar reinforcement plate 16 are fixedly connected to the lower rail 12 through the first welding end 124 and the second welding end 125, which is beneficial to improve the stability and reliability of the connection between the B-pillar lower reinforcement plate 15 and the C-pillar reinforcement plate 16 and the lower rail 12, reduce the risk of mutual separation of the two due to a collision, and further reduce the risk of deformation of the lower rail 12, improve the structural rigidity of the lower rail 12, and thus improve the crashworthiness of the lower rail 12.

[0074] In a possible implementation, as shown in the figure, Figure 5 the rocker 1 further includes a limiting piece 18, which is located outside the end portion of the lower rail 12 along the length direction of the rocker 1.

[0075] In this embodiment, when the middle door of the vehicle is opened or closed, the limiting piece 18 can limit the continuous sliding of the middle door along the rail to cause the middle door to be separated from the rail along the length direction of the rocker 1. At the same time, the limiting piece 18 can be made of a material with a buffering performance to reduce the risk of wear of the middle door when the middle door abuts against the limiting piece 18.

[0076] In a possible implementation, as shown in the figure, Figure 5 Figure 5 the lower shell 122 is provided with a sealing strip 123.

[0077] ​The outer surface of the lower shell 122 is provided with a sealing strip 123. When the middle door is closed, the middle door will press the sealing strip 123, thereby reducing the risk of sand and stones brought by the wheels of the vehicle entering the lower guide rail 12 during driving, and further reducing the risk of affecting the normal opening and closing of the middle door.

[0078] The application also provides a vehicle comprising the rocker 1 in any of the above embodiments.

[0079] When the rocker 1 is used in a vehicle, the support 13 can support the lower guide rail 12 in the height direction of the rocker 1, thereby reducing the risk of deformation of the lower guide rail 12 caused by the impact force of the rocker 1, and further improving the structural strength of the lower guide rail 12, thereby reducing the risk of deformation of the rocker 1, improving the structural strength of the rocker 1, and improving the structural strength of the vehicle.

[0080] Meanwhile, the closed structure formed by the lower guide rail 12, the rocker beam assembly 19, the B-pillar lower reinforcement plate 15, the C-pillar reinforcement plate 16 and the B-pillar reinforcement plate 17 enables the impact force to be transmitted and dispersed to the vehicle, thereby improving the transmission path of the impact force, reducing stress concentration, and further reducing the risk of deformation of the rocker 1, thereby reducing the risk of deformation of the vehicle, improving the torsional stiffness of the vehicle, and improving the safety of the vehicle.

[0081] The above is only a specific implementation of the application, but the protection scope of the application is not limited to this. Any changes or replacements within the technical scope disclosed in the application should be covered within the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
