[0028] The subframe assembly 100 according to a first aspect of the present invention is described below with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, the subframe assembly 100 according to the first aspect of the present invention includes: a subframe body and a reinforcing member 2. The subframe body includes a plurality of beams 1, each beam 1 having a cavity 11. The reinforcing member 2 is disposed within the cavity 11 and includes a first side plate 21, a second side plate 22, a third side plate 23, and a fourth side plate 24 connected end-to-end in sequence. The first side plate 21 and the third side plate 23 are aligned along a first direction (e.g., ...). Figure 3 As shown in the figure, e1) are arranged opposite to each other and spaced apart, and the second side plate 22 and the fourth side plate 24 are arranged along the second direction (e.g. Figure 3 As shown in the figure, e2) are arranged opposite to each other and spaced apart. The second direction is perpendicular to the first direction. In the direction from both ends to the center, the first side plate 21 and the third side plate 23 extend inclinedly towards each other. The center positions of the first side plate 21, the second side plate 22, the third side plate 23 and the fourth side plate 24 in the extension direction are respectively connected to the inner wall surface of the cavity 11.

[0030] That is, the first side plate 21 is connected to the inner wall surface of the cavity 11 along the first direction at the center position in the second direction, the third side plate 23 is connected to the inner wall surface of the cavity 11 along the other side in the first direction at the center position in the second direction, the second side plate 22 is connected to the inner wall surface of the cavity 11 along the second direction at the center position in the first direction, and the fourth side plate 24 is connected to the inner wall surface of the cavity 11 along the other side in the second direction at the center position in the first direction. In other words, the reinforcing member 2 is connected to the inner wall surfaces of the cavity 11 along the first and second directions, and the reinforcing member 2 is supported between the inner wall surfaces of the cavity 11 on both sides opposite to each other along the first direction, and also between the inner wall surfaces of the cavity 11 on both sides opposite to each other along the second direction.

[0031] For ease of description, the sidewall connecting beam 1 to the first side plate 21 is defined as the first sidewall 15, the sidewall connecting beam 1 to the second side plate 22 is defined as the second sidewall 16, the sidewall connecting beam 1 to the third side plate 23 is defined as the third sidewall 17, and the sidewall connecting beam 1 to the fourth side plate 24 is defined as the fourth sidewall 18, and these definitions are incorporated into the following description. Figure 2 and Figure 3 As shown, in the direction from both ends of the second direction to the center position, the first sidewall 15 and the third sidewall 17 extend obliquely in a direction away from each other.

[0032] Among them, since the first side plate 21 and the second side plate 22 extend inclined towards each other in the direction from both ends to the center, when the beam 1 is subjected to compression in the second direction (such as... Figure 3 As shown by the hollow arrows on opposite sides of beam 1 along the second direction, the compressive force acts on the first sidewall 15 and the third sidewall 17, causing the first sidewall 15 and the third sidewall 17 to tend to deform towards each other at their center along the second direction (e.g., ...). Figure 3 (The solid arrows shown indicate the directions on opposite sides of beam 1 along the first direction). However, at this time, the compressive force acts on the first side plate 21 and the third side plate 23, causing the first side plate 21 and the second side plate 22 to tend to deform towards each other at their center positions along the second direction. The connection between the first side plate 21 and the first side wall 15 allows them to form a mutual traction state, thus counteracting the deformation of the first side plate 21 and the first side wall 15. Similarly, the connection between the third side plate 23 and the third side wall 17 can counteract the deformation of the third side plate 23 and the third side wall 17. When beam 1 is subjected to compression along the first direction, the connection between the second side plate 22 and the second side wall 16, and the connection between the fourth side plate 24 and the fourth side wall 18, counteract the deformation of the second side plate 22, the second side wall 16, the fourth side plate 24, and the fourth side wall 18, which will not be elaborated further here.

[0033] In other words, the connection between beam 1 and reinforcement 2 can form a negative Poisson's ratio structure, which can effectively improve the stiffness of beam 1 and increase the first torsional mode and first bending mode frequency of subframe assembly 100. This can reduce the transmission of vehicle suspension and other vibrations to the vehicle body through subframe assembly 100, thereby improving the vehicle's NVH performance and enhancing driving and riding comfort.

[0034] According to the auxiliary frame assembly 100 of the first aspect of the utility model, the beam body 1 and the reinforcing part 2 are connected to form a negative Poisson's ratio structure, which can improve the rigidity of the beam body 1 and the first-order torsional mode and the first-order bending mode frequency of the auxiliary frame assembly 100, thereby reducing the transmission of vehicle suspension vibration to the vehicle body through the auxiliary frame assembly 100, and improving the NVH performance of the vehicle to improve the comfort of driving and riding.

[0035] According to some embodiments of the utility model, the first side plate 21 and the third side plate 23 are arc-shaped. The arc-shaped first side plate 21 and the third side plate 23 can effectively avoid stress concentration on the first side plate 21 and the third side plate 23, thereby avoiding the risk of fracture and damage caused by stress concentration, improving the structural strength of the reinforcing part 2, and improving the reinforcing effect of the reinforcing part 2 on the beam body 1.

[0036] According to some embodiments of the utility model, the second side plate 22 and the fourth side plate 24 extend straight along the first direction. That is, the second side plate 22 and the fourth side plate 24 are straight. Thus, the shape of the reinforcing part 2 can be simplified, thereby reducing the production and processing difficulty of the reinforcing part 2.

[0037] According to some embodiments of the utility model, the first side plate 21 and the third side plate 23 are arc-shaped, and the second side plate 22 and the fourth side plate 24 extend straight along the first direction. Thus, the structural strength of the reinforcing part 2 can be improved while reducing the production and processing difficulty of the reinforcing part 2.

[0038] According to some embodiments of the utility model, the reinforcing part 2 further includes a first connecting plate 25 and a second connecting plate 26. Along the second direction, the middle part of the first side plate 21 is connected to the inner wall surface of the cavity 11 through the first connecting plate 25, and the middle part of the third side plate 23 is connected to the inner wall surface of the cavity 11 through the second connecting plate 26. Among them, as shown in FIG. 1, the first connecting plate 25 and the second connecting plate 26 are arranged on the same side of the beam body 1. Figure 2As shown, in order to meet the requirements of the negative Poisson's ratio structure, the space between the first side plate 21 and the first side wall 15 is narrow at both ends and wide in the middle, and the space between the third side plate 23 and the third side wall 17 is narrow at both ends and wide in the middle, so that the distance between the central position of the first side plate 21 along the second direction and the central position of the first side wall 15 along the second direction is far, and the distance between the central position of the third side plate 23 along the second direction and the central position of the third side wall 17 along the second direction is far. Therefore, by arranging the first connecting plate 25 at the central position of the first side plate 21 along the second direction, the connection between the central position of the first side plate 21 along the second direction and the central position of the first side wall 15 along the second direction is facilitated, and the second connecting plate 26 is arranged at the central position of the third side plate 23 along the second direction. The connection between the central position of the third side plate 23 along the second direction and the central position of the third side wall 17 along the second direction is facilitated to meet the installation requirements of the reinforcing member 2.

[0039] According to some embodiments of the present application, a through connecting hole 12 is arranged on the outer peripheral wall of the cavity 11, and the connecting hole 12 is arranged opposite to part of the reinforcing member 2. That is, the connecting hole 12 penetrates to the outer surface of the beam body 1. Among them, since the cavity 11 is a closed cavity, that is, the cross section of the beam body 1 is a closed curve, and the reinforcing member 2 is installed in the cavity 11. Therefore, by arranging the connecting hole 12 communicating with the cavity 11 on the outer surface of the beam body 1, it is convenient to observe the position of the reinforcing member 2 in the cavity 11 through the connecting hole 12, and it is convenient to weld the reinforcing member 2 through the connecting hole 12. For example, the welding tool can be aligned with the part of the reinforcing member 2 opposite to the connecting hole 12 through the connecting hole 12 to realize the welding of the structure of the reinforcing member 2 and the beam body 1 in the connecting hole 12 region.

[0040] According to some embodiments of the present application, as shown in the Figure 4 As shown, the reinforcing member 2 is provided with a connecting flange 27, and the connecting hole 12 is arranged opposite to the connecting flange 27. Therefore, by arranging the connecting flange 27, the welding position of the reinforcing member 2 and the beam body 1 can be better increased, and the connection of the reinforcing member 2 and the beam body 1 through the connecting hole 12 can be facilitated through the connecting flange 27, that is, the difficulty of welding the reinforcing member 2 on the beam body 1 through the connecting hole 12 can be reduced, so that the assembly efficiency of the reinforcing member 2 can be improved. In addition, through the connecting flange 27, the connecting hole 12 can be better blocked, and at the same time the structure of the reinforcing hole 12 can be formed to form a sealing structure to avoid rainwater entering the inside of the beam body 1 while ensuring the structural strength of the opening region of the beam body 1.

[0041] According to some embodiments of the utility model, the beam body 1 includes first plate piece 13 and second plate piece 14 which are independently formed respectively, and first plate piece 13 and second plate piece 14 are connected and jointly define the cavity 11. Since first plate piece 13 and second plate piece 14 are independently formed respectively, during the assembly process of the auxiliary frame assembly 100, the reinforcing member 2 can be fixed on one of first plate piece 13 and second plate piece 14 before the connection of first plate piece 13 and second plate piece 14, and then the connection of first plate piece 13 and second plate piece 14 is carried out, and the fixing process of the reinforcing member 2 and the other one of first plate piece 13 and second plate piece 14 is completed. Therefore, the difficulty of installing the reinforcing member 2 into the cavity 11 can be reduced, so that the installation efficiency of the reinforcing member 2 can be improved.

[0042] According to some embodiments of the utility model, first plate piece 13 is U-shaped and opens towards second plate piece 14, second plate piece 14 is U-shaped and opens towards first plate piece 13, first side plate 21, second side plate 22 and third side plate 23 are connected with first plate piece 13, fourth side plate 24 is connected with second plate piece 14, the edge of fourth side plate 24 away from second side plate 22 is provided with connecting flange 27, and the side wall of second plate piece 14 away from first plate piece 13 is formed with connecting hole 12 opposite to connecting flange 27. Therefore, during the assembly process of the auxiliary frame body, the reinforcing member 2 can be installed into first plate piece 13, and the welding connection of first side plate 21, second side plate 22 and third side plate 23 with first plate piece 13 is completed, then second plate piece 14 is installed on first plate piece 13, and connecting flange 27 is aligned with connecting hole 12, and then connecting flange 27 is welded on the side wall of second plate piece 14 away from first plate piece 13 through connecting hole 12. Therefore, the difficulty of installing the reinforcing member 2 into the cavity 11 can be reduced, so that the installation efficiency of the reinforcing member 2 can be improved.

[0043] In a specific example, first plate piece 13 and second plate piece 14 are arranged along the second direction, and the second direction is the up-down direction. Along the first direction, the opposite two side walls of second plate piece 14 are located on the opposite two sides of first plate piece 13.

[0044] According to some embodiments of the utility model, the plurality of beam bodies 1 include front cross beam 1a and rear cross beam 1b, the first direction is the front-rear direction, and the second direction is the up-down direction. The front cross beam 1a and the rear cross beam 1b are both provided with a plurality of reinforcing members 2 arranged along the left-right direction at intervals. Therefore, through the plurality of reinforcing members 2 arranged along the left-right direction in the front cross beam 1a and the rear cross beam 1b, the rigidity of the front cross beam 1a and the rear cross beam 1b can be strengthened at multiple positions in the left-right direction, so that the modal of the auxiliary frame assembly 100 can be further improved. In addition, the space of the cavity 11 in the front cross beam 1a and the rear cross beam 1b is large, which is convenient for the arrangement of the reinforcing member 2, so as to reduce the installation difficulty of the reinforcing member 2.

[0045] In one specific example, the plurality of beam bodies 1 further comprises a left longitudinal beam 1c and a right longitudinal beam 1d, the left longitudinal beam 1c is connected with the left end of the front cross beam 1a and the rear cross beam 1b respectively, and the right longitudinal beam 1d is connected with the right end of the front cross beam 1a and the rear cross beam 1b respectively.

[0046] It should be noted that the installation position and the number of the reinforcing member 2 can be flexibly set according to the modal requirements of the subframe body and the installation positions that can be provided. For example, when the space of the cavity 11 in the left longitudinal beam 1c and the right longitudinal beam 1d is large, the reinforcing member 2 can also be arranged in the left longitudinal beam 1c and the right longitudinal beam 1d.

[0047] According to some embodiments of the present application, the reinforcing member 2 is an integrally formed member. Thus, the integrally formed structure not only can ensure the stability of the structure and performance of the plurality of parts of the reinforcing member 2, but also is convenient to form, simple to manufacture, and saves the assembly parts and the connecting process used between the plurality of parts of the reinforcing member 2, thereby reducing the production cost and greatly improving the assembly efficiency of the plurality of parts of the reinforcing member 2, ensuring the connection reliability of the plurality of parts of the reinforcing member 2. In addition, the overall strength and stability of the integrally formed structure is higher, and the service life is longer.

[0049] The vehicle according to the second aspect of the present application comprises a subframe assembly 100.
