[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention provides a buffer reinforcement structure for the left support bracket at point D of an engine, including a first bracket 1 and a second bracket 11; mounting holes 12 are provided in the middle of the first bracket 1 and the second bracket 11; multiple sets of mounting holes 12 are provided in the middle of the first bracket 1 and the second bracket 11, and are arranged symmetrically; a shock-absorbing component is provided between the first bracket 1 and the second bracket 11; a buffer component is provided on the first bracket 1 through the shock-absorbing component; a reinforcement component is provided on the inner sidewall of the first bracket 1 and the second bracket 11; a dustproof component is provided on the first bracket 1 through the shock-absorbing component; in operation, fixing bolts are inserted into the middle of the mounting holes 12, the first bracket 1 is installed on the engine, and the second bracket 11 is installed on the vehicle body through fixing bolts, connecting the engine and the vehicle body together. When the engine vibrates, the vibration is transmitted from the first bracket 1 to the second bracket 11. The damping component and the buffer component reduce the transmitted vibration, the reinforcing component increases the structural strength of the first bracket 1 and the second bracket 11, and the dustproof component blocks impurities or foreign objects falling on the damping component. Through the above structure, the damping component and the buffer component reduce the vibration transmitted from the engine to the vehicle body, forming the left engine bracket buffer reinforcement structure. This realizes the function of connecting the engine and the vehicle body together and buffering the vibration transmitted from the engine to the outside. It solves the problem of the vibration generated by the engine being transmitted to the vehicle body through the bracket, causing the vehicle body to shake, improves the stability of the engine when it is working, and reduces the problem of vibration transmitted to the vehicle body causing the vehicle body to shake.

[0024] like Figures 1 to 3As shown, the shock absorption assembly includes a guide rod 13, a return spring 14, and a shock absorber 15. The bottom end of the guide rod 13 is fixedly connected to the top of the second bracket 11. The guide rod 13 is slidably fitted in the middle of the first bracket 1. The shock absorber 15 is installed on the outer side wall of the guide rod 13 near the second bracket 11. The shock absorber 15 is positioned between the first bracket 1 and the second bracket 11. The return spring 14 is sleeved on the outer side wall of the guide rod 13 away from the shock absorber 15. During operation, the first bracket 1 is mounted on the engine by fixing bolts. When the engine vibrates, the engine causes the first bracket 1 to bounce. The first bracket 1 then vibrates in the guide rod 13. Sliding to the outer wall of rod 13, the return spring 14 and shock absorber 15 suppress the upward bounce of the first bracket 1, reducing the vibration transmitted to the second bracket 11 and the vehicle body. Through the above structure, the return spring 14 and shock absorber 15 reduce the vibration transmitted by the first bracket 1, forming a bracket damping structure. This achieves the function of reducing the vibration transmitted from the engine to the second bracket 11 and the vehicle body, solving the problem of the engine's vibration being transmitted to the vehicle body due to the rigid connection of the engine to the vehicle body, improving the stability of the engine during installation, and reducing the vibration transmitted to the vehicle body causing body shaking.

[0025] like Figure 4 As shown, the buffer assembly includes a fixed ring 2, a rubber sheet 21, and a sliding ring 22.

Multiple sets of rubber sheets 21 are arranged on the inner wall of the fixed ring 2 and are evenly distributed. The outer wall of the sliding ring 22 is fixedly connected to the inner wall of the rubber sheet 21. The sliding ring 22 is slidably connected to the outer wall of the guide rod 13. During operation, when the engine causes the first bracket 1 to bounce, the first bracket 1 causes the fixed ring 2, the rubber sheet 21, and the sliding ring 22 to slide on the outer wall of the guide rod 13. The rubber sheet 21 flexibly connects the guide rod 13 and the first bracket 1 together. When the first bracket 1 vibrates, the rubber sheet 21 reduces the vibration transmitted from the first bracket 1 to the guide rod 13. Through the above structure, the rubber sheet 21 flexibly connects the first bracket 1 and the guide rod 13 together to form a bracket buffer structure, which realizes the function of buffering the vibration transmitted from the first bracket 1 to the guide rod 13. This solves the problem of the vibration generated by the engine being transmitted to the vehicle body through the first bracket 1 and the second bracket 11, and reduces the situation where the first bracket 1 drives the guide rod 13 and the second bracket 11 to vibrate.

[0029] like Figure 1 As shown, the first bracket 1 and the second bracket 11 are made of aluminum alloy. During operation, the first bracket 1 and the second bracket 11 are made of aluminum alloy, which reduces the weight of the parts, improves the lightweight of the vehicle, and increases the structural strength of the bracket.

[0030] During operation, the fixing bolts are inserted into the middle of the mounting hole 12, and the first bracket 1 is mounted on the engine. The second bracket 11 is mounted on the vehicle body via fixing bolts, connecting the engine and the vehicle body. When the engine vibrates, the vibration is transmitted from the first bracket 1 to the second bracket 11. The shock absorption assembly and the buffer assembly weaken the transmitted vibration. The reinforcing assembly increases the structural strength of the first bracket 1 and the second bracket 11. The dustproof assembly blocks impurities or foreign objects falling on the shock absorption assembly. The first bracket 1 is mounted on the engine via fixing bolts. When the engine vibrates, the engine causes the first bracket 1 to bounce. The first bracket 1 slides on the outer wall of the guide rod 13. The return spring 14 and the shock absorber airbag 15 suppress the upward bounce of the first bracket 1, reducing the transmission of vibration to the second bracket 11 and the vehicle body. When the engine causes the first bracket 1 to bounce, the first bracket 1 causes the fixing ring 2, the rubber sheet 21, and the sliding ring 22 to slide on the outer wall of the guide rod 13. The rubber sheet 21 flexibly connects the guide rod 13 and the first bracket 1 together. When the first bracket 1 vibrates, the rubber sheet 21 weakens the vibration transmitted from the first bracket 1 to the guide rod 13. When the first bracket 1 sways on the outer wall of the guide rod 13, the elastic cover 3 covers the return spring 14 to block impurities or foreign objects in the external air. The first reinforcing rib 4 is set on the inner side wall of the first bracket 1 and the second bracket 11 to improve the structural strength of the first bracket 1 and the second bracket 11, reduce the deformation of the first bracket 1 and the second bracket 11, and reduce the stress concentration of the first bracket 1 and the second bracket 11. The second reinforcing rib 5 is set at the bottom of the second bracket 11 to increase the structural strength of the bottom of the second bracket 11, reduce the deformation of the bottom of the second bracket 11, and improve the service life of the second bracket 11.
