Meanwhile, the mounting flange 2121 extends towards the center of the suspension box 200 to increase the connection area between the mounting flange 2121 and the lower plate 500 of the sub-frame assembly 1000, effectively improving the connection strength of the two, and ensuring that the suspension box 200 is not easy to deform or fall off. In addition, the structure that the mounting flange 2121 extends towards the center of the suspension box 200 can improve the torsional resistance of the suspension box 200. When the suspension box 200 is subjected to a torsional force, the mounting flange 2121 can act as an additional support structure to disperse and resist the torsional force, thereby protecting the first suspension mounting point 2111 from damage, and further protecting the suspension and improving reliability.

[0044] Specifically, the sub-frame assembly 1000 includes the lower plate 500 and the first cross beam 300, the first cross beam 300 is located above the lower plate 500 and connected with the lower plate 500, the first cross beam 300 extends along the left-right direction of the vehicle, the first cross beam 300 has a mounting groove 31, at least part of the suspension box 200 is located in the mounting groove 31, and the suspension box 200 is connected with the lower plate 500 through the mounting flange 2121 to realize the connection of the suspension box 200 and the lower plate 500, thereby fixing the suspension box 200. Meanwhile, the mounting flange 2121 extends towards the center of the suspension box 200 to increase the connection area of the suspension box 200 and the lower plate 500, and improve the connection reliability of the suspension box 200 and the lower plate 500. Further, the mounting flange 2121 is welded with the lower plate 500.

[0045] According to the suspension box 200 of the embodiment of the utility model, the body 21 has the first suspension mounting point 2111, which is open at the end opposite to the first suspension mounting point 2111 along the up-down direction of the vehicle and has the mounting flange 2121 extending towards the center of the suspension box 200 to fix the suspension box 200. Meanwhile, the mounting flange 2121 extends towards the center of the suspension box 200 to increase the connection area between the mounting flange 2121 and the lower plate 500 of the sub-frame assembly 1000, effectively improving the connection strength of the two, and ensuring that the suspension box 200 is not easy to deform or fall off, thereby improving the stiffness and strength of the suspension box 200. In addition, the structure that the mounting flange 2121 extends towards the center of the suspension box 200 can improve the torsional resistance of the suspension box 200. When the suspension box 200 is subjected to a torsional force, the mounting flange 2121 can act as an additional support structure to disperse and resist the torsional force, thereby protecting the first suspension mounting point 2111 from damage, and further protecting the suspension and improving reliability.

[0046] In some embodiments of the utility model, such as Figures 4-6As shown, the mounting flange 2121 is provided in multiple, and the multiple mounting flanges 2121 are arranged along the circumferential direction of the body 21.

[0047] Therefore, by connecting the multiple mounting flanges 2121 with the lower plate 500 of the sub-frame assembly 1000, the multiple mounting flanges 2121 can effectively disperse stress, effectively improve the overall structural strength and stability of the suspension box 200.

[0048] In some embodiments of the present application, as shown in Figures 4-6 As shown, the connection groove 2123 is provided between any two adjacent mounting flanges 2121, and the connection groove 2123 extends to the body 21. Therefore, by forming a certain concave-convex structure through the connection groove 2123, the external force can be more effectively dispersed, so that the suspension box 200 can better maintain its shape and structural stability when subjected to pressure or impact force, thereby enhancing the overall structural strength of the suspension box 200. At the same time, when the multiple mounting flanges 2121 are welded to the lower plate 500, the connection groove 2123 provides a welding position for welding operation, facilitating the connection of the mounting flange 2121 and the lower plate 500, effectively improving the welding quality and efficiency, thereby improving the overall reliability.

[0049] In some embodiments of the present application, as shown in Figures 4-6 As shown, the body 21 includes a top plate 211 and a side plate 212. The top plate 211 has a first suspension mounting point 2111, and the side plate 212 extends along the length direction of the top plate 211 and is connected to the outer edge of the top plate 211 at the upper end, and the lower end has a mounting flange 2121.

[0051] In some embodiments of the present application, as shown in Figures 4-6As shown, the side plate 212 has a notch 2122 on one side along the front-rear direction of the vehicle. It can be understood that, since the first suspension mounting point 2111 on the top plate 211 provides a mounting position for the suspension, the structure of the notch 2122 on the side plate 212 makes the suspension enter the suspension box 200 through the notch 2122 to cooperate with the first suspension mounting point 2111, thereby facilitating the installation of the suspension.

At the same time, since the first cross beam 300 is connected to the lower plate 500, the suspension box 200 is connected to the first cross beam 300 and the lower plate 500 respectively, which effectively improves the connection strength between the suspension box 200, the first cross beam 300 and the lower plate 500, thereby improving the overall structural strength of the auxiliary frame assembly 1000.

[0055] In addition, the mounting flange 2121 extends towards the center of the suspension box 200, thereby increasing the connection area between the mounting flange 2121 and the lower plate 500, effectively improving the connection strength between them, and ensuring that the suspension box 200 is not easily deformed or detached. In addition, the structure of the mounting flange 2121 extending towards the center of the suspension box 200 can improve the torsional resistance of the suspension box 200. When the suspension box 200 is subjected to a torsional force, the mounting flange 2121 can act as an additional support structure to disperse and resist the torsional force, thereby protecting the first suspension mounting point 2111 from damage, and further protecting the suspension and improving reliability.

At the same time, the mounting flange 2121 extends towards the center direction of the suspension box 200, so that the connecting area between the mounting flange 2121 and the lower plate 500 is increased, the connecting strength of the two is effectively improved, the deformation or falling off of the suspension box 200 is prevented, and the rigidity and strength of the suspension box 200 are improved. In addition, the structure that the mounting flange 2121 extends towards the center direction of the suspension box 200 can improve the torsional capacity of the suspension box 200, when the suspension box 200 is subjected to torsional force, the mounting flange 2121 can be used as an additional support structure to disperse and resist the torsional force, so as to protect the first suspension mounting point 2111 from being damaged, and further protect the suspension and improve the reliability of the auxiliary frame assembly 1000.

[0057] In some embodiments of the utility model, as shown in Figures 4-6 The lower plate 500 has a second suspension mounting point 54 arranged opposite to the first suspension mounting point 2111. Therefore, the first suspension mounting point 2111 and the second suspension mounting point 54 jointly provide a mounting position for the suspension, further ensuring the accurate positioning of the suspension, so as to ensure the stability of the power assembly under various working conditions. At the same time, the first suspension mounting point 2111 and the second suspension mounting point 54 are arranged opposite in the up-down direction, so as to form an effective support structure, improve the rigidity and durability of the suspension, and further improve the handling and stability of the vehicle.

[0058] In some embodiments of the utility model, as shown in Figures 4-6 The first cross beam 300 includes a first plate 32 and a second plate 33. The first plate 32 is arranged above the lower plate 500 and spaced apart from the lower plate 500, the first plate 32 has a matching groove, the second plate 33 is two and extends along the left-right direction, the upper ends of the two second plates 33 are respectively connected with the two ends of the first plate 32 along the front-rear direction of the vehicle, the lower ends of the two second plates 33 are respectively connected with the lower plate 500, one of the second plates 33 has a matching hole communicated with the matching groove, the matching groove and the matching hole form an installation groove 31, the first plate 32 is arranged above the suspension box 200 and connected with the body 21, and the second plate 33 forming the matching hole is connected with the body 21.

[0059] Thus, the first cavity is formed by the first plate 32, the two second plates 33 and the lower plate 500, the cavity structure has high strength, the structural strength of the subframe assembly 1000 is increased, impact energy can be effectively absorbed and dispersed in the collision, thereby effectively reducing vibration and noise. At the same time, the weight of the subframe assembly 1000 can be reduced to realize lightweight design, so that the modal frequency of the subframe assembly 1000 can be improved, the modal frequency of the subframe assembly 1000 is avoided to be coupled with the rotating speed frequency of the engine or motor under the acceleration working condition, so as to reduce the resonance risk, the vibration and noise can be blocked from entering the vehicle body, and the acceleration roar or motor howling problem caused by resonance can be effectively inhibited.

[0060] At the same time, the mounting groove 31 is formed by the matching groove and the matching hole, so that the mounting groove 31 can avoid the suspension box 200, and the subframe assembly 1000 can be smoothly assembled. Specifically, the assembly process of the subframe assembly 1000 is as follows: the suspension box 200 is located above the lower plate 500, the mounting flange 2121 is connected with the lower plate 500, the first cross beam 300 is mounted from top to bottom above the lower plate 500, and the first plate 32 is located above the suspension box 200.

[0062] Further, one side of the side plate 212 of the body 21 along the front-rear direction of the vehicle has a notch 2122 communicating with the matching hole. It can be understood that, since the first suspension mounting point 2111 on the top plate 211 and the second suspension mounting point 54 on the lower plate 500 provide mounting positions for the suspension, the structure of the notch 2122 and the matching hole enables the suspension to smoothly enter the suspension box 200 and cooperate with the first suspension mounting point 2111 and the second suspension mounting point 54, thereby facilitating the installation of the suspension.

[0063] In some embodiments of the present application, as shown in Figures 1-3 As shown in the drawings, the subframe assembly 1000 further comprises a second cross beam 700, the second cross beam 700 is arranged in the front-rear direction of the vehicle and is spaced apart from the first cross beam 300, and the second cross beam 700 is located above the lower plate 500 and is connected with the lower plate 500. Thus, the first cross beam 300 and the second cross beam 700 are both connected with the lower plate 500, thereby improving the strength of the subframe assembly 1000 as a whole, and further improving the stability of the vehicle using the subframe assembly 1000.

At the same time, the weight of the subframe assembly 1000 can be reduced to achieve lightweight design, so as to improve the modal frequency of the subframe assembly 1000, avoid the coupling of the modal frequency of the subframe assembly 1000 and the rotating speed frequency under the acceleration working condition of the engine or motor, reduce the risk of resonance, and block the vibration and noise from entering the vehicle body, thereby effectively suppressing the problem of acceleration roar or motor howling caused by resonance.

[0065] It should be noted that the first cross beam 300 can be a front cross beam, and the second cross beam 700 can be a rear cross beam. Of course, the first cross beam 300 can also be a rear cross beam, and the second cross beam 700 can be a front cross beam.

[0067] It can be understood that the first cross beam 300 connected with the lower plate 500 extends along the left and right directions as shown in Figure 1 , and the left and right ends are connected with the upper plate 600, which can enhance the rigidity of the vehicle head and provide fixed mounting points for components such as engines, suspensions, etc. The second cross beam 700 extending along the left and right directions is located behind the first cross beam 300 and is connected with the lower plate 500, and the left and right ends of the second cross beam 700 are connected with the ends of the upper plate 600 away from the first cross beam 300, which can improve the stability of the vehicle tail and provide fixed positions for components such as fuel tanks, etc. The upper plate 600 is two upper plates arranged at the left and right ends of the upper plate 600, which can absorb impact force when the vehicle is side-impacted and provide fixed mounting points for components such as control arms, stabilizer bars and steering gears, etc.
