[0033] The suspension vibration-damping pad 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 4 As shown, the suspension vibration damping pad 1 according to the embodiment of the utility model comprises an outer frame 100 , a vibration damping cushion 200 and an inner frame 300 .

[0035] The exoskeleton 100 is suitable for being installed on a vehicle frame, and a receiving hole 110 is configured at the center of the exoskeleton 100. The vibration-damping cushion 200 partially extends into the receiving hole 110. The inner frame 300 is connected to the upper part of the vibration-damping cushion 200 and is located on the side of the exoskeleton 100 facing the powertrain, and the upper part of the inner frame 300 is suitable for installing a powertrain suspension bracket.

[0036] For example, the outer frame 100 is a hollow structure, and a receiving hole 110 is configured at the hollow structure. The inner frame 300 is installed in the receiving hole 110 on the side facing the longitudinal beam of the frame, and the outer contour of the inner frame 300 is adapted to the inner contour of the outer frame 100. The outer frame 100 is a cast aluminum part, and the vibration-damping cushion 200 can be a vibration-damping structural part such as rubber, which is tightly connected to both sides of the lower part of the inner frame 300. The part where the inner frame 300 is connected to the lower part of the outer frame 100 is fixedly connected through the vibration-damping cushion 200.

[0037] According to the suspension vibration damping pad 1 of the embodiment of the utility model, a composite vibration damping structure is formed by installing the outer frame 100, the inner frame 300 and the vibration damping pad 200. The vibration damping pad 200 plays a vibration damping role between the outer frame 100 and the inner frame 300. According to the suspension vibration damping pad 1 of the embodiment of the utility model, during the driving process of the vehicle, the engine will vibrate, and the inner frame 300 will receive the transmitted vibration, which will be transmitted to the outer frame 100 after the vibration damping effect of the vibration damping pad 200. The vibration of the engine is difficult to be transmitted to the frame through the vibration absorption effect of the suspension vibration damping pad 1, thereby providing a more stable and comfortable riding experience for the passengers in the vehicle. The hollow structure of the exoskeleton 100 can increase the contact area between the vibration-damping cushion 200 and the exoskeleton 100, and the vibration-damping cushion 200 can be more fully extended into the receiving hole 110, and the vibration-damping cushion 200 is distributed on both sides of the receiving hole 110. The vibration-damping cushions 200 on both sides can absorb and disperse vibration forces in multiple directions, increase the vibration-damping area, and reduce the vibration transmitted to the longitudinal beam of the frame, thereby improving the vibration isolation effect. While ensuring the structural strength of the exoskeleton 100, the amount of material used is reduced, the production cost is saved, the weight of the exoskeleton 100 is reduced, and a lightweight structure is achieved.

[0038] Therefore, the suspension vibration-damping pad 1 according to the embodiment of the utility model has the advantages of improved vibration isolation performance and high lightness.

[0039] In some specific embodiments of the present invention, Figure 4 As shown, the vibration-damping cushion 200 includes a side connection portion 210, a front connection portion 220, and a rear connection portion 230. The side connection portion 210 is connected to the side of the inner frame 300 facing the longitudinal beam of the frame, and the side connection portion 210 extends into the receiving hole 110. The front connection portion 220 is connected to the front side of the bottom of the side connection portion 210, and is connected to the front side of the bottom of the inner frame 300, and the front connection portion 220 extends into the receiving hole 110. The rear connection portion 230 is connected to the rear side of the bottom of the side connection portion 210, and is connected to the rear side of the bottom of the inner frame 300, and the rear connection portion 230 extends into the receiving hole 210.

[0040] Among them, the outer contour of the side connection part 210 is consistent with the contour shape of the upper side of the exoskeleton 100 and is arranged at intervals. The inclination angles of the front connection part 220 and the rear connection part 230 are the same as the inclination angles of the lower part of the inner skeleton 300 and are tightly connected to the inner skeleton 300, ensuring that the vibration-damping pad 200 can be firmly fixed between the exoskeleton 100 and the inner skeleton 300, so that these external forces can be more comprehensively contacted and absorbed, providing a larger vibration-damping area and a better vibration-damping effect, thereby improving the comfort and safety of the vehicle.

[0041] In some specific embodiments of the utility model, the suspension vibration damping pad 1 further includes an insert plate 400, which is connected to the bottom of the vibration damping pad 200, and extends into the receiving hole 110 and is fixed to the receiving hole 110. The insert plate 400 is fixed to both sides of the bottom of the vibration damping pad 200. By fixing the vibration damping pad 200 to the insert plate 400 and extending them into the receiving hole 110 together, it can be ensured that the vibration damping pad 200 is correctly installed at the designated position of the suspension vibration damping pad 1 structure to prevent it from moving or offsetting during the driving of the vehicle. In addition, the insert plate 400 can also provide additional support, which can improve the structural strength and durability of the suspension vibration damping pad 1, and effectively absorb and disperse the forces from other structures.

[0042] In some specific embodiments of the present invention, Figure 1 and Figure 4 As shown, the plug plate 400 includes a front plug plate 410 and a rear plug plate 420. The front plug plate 410 is connected to the bottom of the front connecting portion 220 and fixed to the receiving hole 110. The rear plug plate 420 is connected to the bottom of the rear connecting portion 230 and fixed to the receiving hole 110. Through the fixed connection between the front plug plate 410 and the rear plug plate 420 and the receiving hole 110, the stable connection between the vibration-damping pad 200 and other components is ensured, loosening or falling off during use is prevented, and a balancing force is provided on the left and right sides, ensuring the stability and reliability of the vibration-damping pad 200. At the same time, the front plug plate 410 and the rear plug plate 420 can enhance the structural strength of the suspension vibration-damping pad 1, can effectively absorb and reduce the vibration of the vehicle, and improve the stability and comfort of the vehicle suspension.

[0043] In some specific embodiments of the present invention, Figure 1 and Figure 4 As shown, the front board 410 and the rear board 420 are configured with limiting flanges 411 on opposite sides of the thickness direction of the outer frame 110 , and the limiting flanges 411 are engaged with the edge of the receiving hole 110 to be fixed to the receiving hole 110 .

[0044] The front board 410 and the rear board 420 can be engaged with the edge of the receiving hole 110 and fixed to the outer frame 100 by the limiting flange 411. The relative stability of the positions of the front board 410 and the rear board 420 can be ensured by the limiting flange 411, and no slippage or looseness will occur, thereby fixing the suspension vibration damping pad 1. The limiting flange 411 can also increase the structural strength of the outer frame 100 and resist the force exerted on the suspension system.

[0045] In some specific embodiments of the present invention, Figure 3As shown, the middle part of the exoskeleton 100 along the front-back direction is constructed with a limiting portion 101 protruding in the direction of the receiving hole 110, and the side connecting portion 210 is constructed with a limiting groove 211 adapted to the shape of the limiting portion 101, and the limiting groove 211 is received in the limiting portion 101. The structure of the limiting portion 101 and the limiting groove 211 can provide stability and positioning functions. When the vibration-damping pad 1 is installed in the receiving hole 110, the cooperation between the limiting portion 101 and the limiting groove 211 can ensure its accurate position and prevent unnecessary movement or swinging during use. At the same time, the movement range of the vibration-damping pad 200 can be limited by the limiting portion 101 and the limiting groove 211, preventing the vibration-damping pad 200 from exceeding the safety range during movement, thereby protecting the stability and safety of the overall structure of the suspension vibration-damping pad 1.

[0046] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the bottom of the inner frame 300 is constructed with a vertical positioning pin 310 extending upward, and the vertical positioning pin 310 is suitable for positioning with the powertrain suspension bracket. The side of the outer frame 100 facing the frame is constructed with a frame positioning pin 102, and the frame positioning pin 102 is suitable for positioning with the frame hole of the frame longitudinal beam. The fixed position of the vertical positioning pin 310 has an auxiliary effect on the installation of the powertrain suspension bracket, which facilitates the accurate positioning and installation of the suspension vibration damping pad 1 and the powertrain suspension bracket. During the installation process, unnecessary installation processes are reduced, installation time is saved, and assembly efficiency is improved. At the same time, the vertical positioning pin 310 also provides additional supporting force. By cooperating with the powertrain suspension bracket, the suspension vibration damping pad 1 can always remain in a stable position, thereby providing a more stable and reliable suspension system.

[0047] In addition, the frame locating pins 102 are respectively located on both sides of the exoskeleton 100. The frame locating pins 102 on both sides provide convenience for installation and connection between the suspension vibration damping pad 1 and the frame longitudinal beam. The frame locating pins 102 correspond to the frame holes, which reduces the time for alignment with the frame longitudinal beam during manual installation operations and improves the assembly efficiency of the suspension vibration damping pad 1.

[0048] In some specific embodiments of the present invention, the exoskeleton is a cast aluminum part or a ductile iron part. Cast aluminum has a lower density, so it can help achieve a lightweight structure of the suspension vibration damping pad 1. Reducing the weight of the suspension vibration damping pad 1 can effectively reduce the weight of the entire vehicle, thereby improving fuel efficiency and vehicle performance. At the same time, cast aluminum generally has good corrosion resistance, which can protect the exoskeleton 100 from corrosion by chemical substances in the environment, thereby improving the durability and reliability of the suspension vibration damping pad 1.

[0049] Ductile iron has higher strength and durability than cast aluminum, and can withstand greater loads and impacts, thereby improving the structural stability and durability of the suspension vibration damping pad 1. Ductile iron also has good wear resistance and can resist abrasion. Under harsh road conditions, the exoskeleton 100 made of ductile iron can provide better protection and durability.

[0050] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the bottom of the exoskeleton 100 is constructed with a wire tie plate portion 103 extending forward and backward and arranged horizontally, and the wire tie plate portion 103 is suitable for tying cable ties to fix the wire harness. The wire harness can be effectively fixed by the wire tie plate portion 103 to prevent the wire harness from loosening, and the wiring is smoother, ensuring the correct fixation of the wire harness, and improving the aesthetics of the overall structure of the vehicle. At the same time, the wire harness can be protected by fixing it on the wire tie plate portion 103. In the suspension system of the vehicle, the wire harness is often subjected to vibrations from the road surface and other external forces, and is easily damaged. Fixing it on the wire tie plate portion 103 enables the wire harness to be fixed in a relatively safe position, reducing the risk of damage to the wire harness.
