[0026] As a technical optimization solution of the present invention, by setting a reinforced support buffer, the reinforcing rib 41 can reinforce the support block 3 and the left front support body 1, thereby enhancing the impact resistance of the left front support body 1 during use. The buffer block 42 can buffer the outer side of the support block 3 during use, reducing the impact of the impact force on the left front support body 1 during use. At the same time, the support plate 43 can first buffer the impact force during use to reduce the impact force, thereby effectively improving the anti-buffering effect of the left front support body 1. The movable block 44 can provide buffering support to the inner side of the buffer plate 7 under the support of the reinforcing rib 41 during use, thereby enhancing the buffering effect of the impact force during use.

[0027] refer to Figure 2 The connecting buffer assembly 5 includes a hydraulic buffer 51, and a mounting plate 52 is fixedly connected to the outer side of the hydraulic buffer 51. A mounting groove 53 is opened on the outer side of the mounting plate 52. There are several mounting grooves 53, and the several mounting grooves 53 are arranged at equal distances.

[0028] As a technical optimization solution of the present invention, by setting a connecting buffer assembly 5, the hydraulic buffer 51 can buffer the outer side of the left front support body 1 during use. The hydraulic buffer 51 contains hydraulic oil and a piston structure. When impacted, the piston moves in the cylinder, and the hydraulic oil generates a damping force through the throttle hole. This damping force can effectively consume the impact energy. The buffering effect of the hydraulic buffer 51 can be controlled by adjusting parameters such as the size of the throttle hole and the viscosity of the hydraulic oil, and can more accurately resist impacts of different intensities. The mounting plate 52 and the mounting groove 53 can be easily installed and fixed, which enhances convenience in use.

[0029] refer to Figure 3 The outer side of the support plate 43 is fixedly connected to a connecting plate 6 , and the outer side of the connecting plate 6 is fixedly connected to a buffer plate 7 .

[0030] As a technical optimization solution of the present invention, by setting the connecting plate 6 and the buffer plate 7, the connecting plate 6 can connect and support the outer side of the support plate 43 during use, so that the outer side of the support plate 43 can be easily installed and fixed, thereby enhancing the use effect of the support plate 43. At the same time, the buffer plate 7 can buffer the impact force, thereby preventing the support plate 43 from being subjected to vertical impact force, resulting in an inability to effectively buffer.

[0031] refer to Figure 2A reinforcement rod 8 is fixedly connected to the outer side of the left front support body 1. There are several reinforcement rods 8, and the reinforcement rods 8 are arranged in a ring shape with equal distances.

[0032] As a technical optimization solution of the present invention, by setting a reinforcement rod 8, the reinforcement rod 8 can reinforce the outer side of the left front support body 1 during use, thereby enhancing the reinforcement stability during use and avoiding unstable support of the left front support body 1 during use.

[0033] refer to Figure 2 The outer side of the support plate 43 is fixedly connected with a protective plate 9, and a buffer hole 10 is opened on the outer side of the protective plate 9. There are several buffer holes 10, and the buffer holes 10 are arranged at equal distances.

[0034] As a technical optimization solution of the present invention, by setting the protective plate 9 and the buffer hole 10, the protective plate 9 can provide protective buffering for the outer side of the support plate 43 during use, thereby enhancing the safety of the support plate 43 during use. At the same time, the buffer hole 10 can disperse the stress to the surrounding area of ​​the hole, change the propagation path of the stress, and play a buffering role.

[0035] refer to Figure 2 The bottom of the connecting plate 6 is fixedly connected with a reinforcing block 11 , and the inner side of the reinforcing block 11 is fixedly connected to the outer side of the supporting plate 43 .

[0036] As a technical optimization solution of the present invention, by setting a reinforcement block 11, the reinforcement block 11 can reinforce the bottom of the connecting plate 6 during use, so that the connecting plate 6 can stably support the inner side of the buffer plate 7 during use, avoiding the situation where the outer side of the connecting plate 6 is broken due to unstable support during use.

[0037] refer to Figure 1 The material of the reinforcing rib 41 is thermally processed steel, and the material of the supporting plate 43 is CFRP.

[0038] As a technical optimization solution of the present invention, by setting reinforcing ribs 41 and support plates 43, the reinforcing ribs 41 are made of heat-treated steel during use. The heat-treated steel undergoes a special heat treatment process, and its strength can reach more than 1500MPa. This type of steel can withstand greater impact forces and is not easily deformed during collisions. The support plate 43 uses CFRP, which can further reduce weight while ensuring strength. Moreover, the carbon fiber material has good energy absorption characteristics and can effectively disperse and absorb energy when impacted, thereby reducing the damage caused by the impact force to the left front support body 1.

[0039] The working principle and use process of the utility model are as follows: when in use, the reinforcing rib 41 can reinforce the support block 3 and the left front support body 1, thereby enhancing the anti-impact effect of the left front support body 1 during use; the buffer block 42 can buffer the outer side of the support block 3 during use, thereby reducing the impact of the impact force on the left front support body 1 during use; at the same time, the support plate 43 can first buffer the impact force during use, thereby reducing the impact force, thereby effectively improving the anti-buffering effect of the left front support body 1; the movable block 44 can buffer the inner side of the buffer plate 7 under the support of the reinforcing rib 41 during use, thereby enhancing the buffering effect of the impact force during use. Impact effect, the hydraulic buffer 51 can buffer the outer side of the left front support body 1 during use. The hydraulic buffer 51 contains hydraulic oil and piston structure. When impacted, the piston moves in the cylinder, and the hydraulic oil generates damping force through the throttle hole. This damping force can effectively consume the impact energy. The buffering effect of the hydraulic buffer 51 can be controlled by adjusting parameters such as the size of the throttle hole and the viscosity of the hydraulic oil, and can more accurately resist impacts of different intensities. The mounting plate 52 and the mounting groove 53 can be easily installed and fixed, which enhances the convenience in use, achieves the effect of impact buffering, and enhances the safety of the left front support.

[0040] To sum up: this impact-resistant rear subframe left front support, by setting a support block 3, a reinforced support component 4 and a connected buffer component 5 to stably reinforce and buffer the left front support body 1, solves the problem that the existing left front support cannot effectively resist impact during use, which results in that when encountering a sudden impact, the left front support will be more seriously damaged than other supports due to the force, affecting the normal use of the left front support and reducing the safety of the left front support.
