[0030] Please see Figure 1-5 This invention provides a technical solution: a cooling module shock-absorbing pad, comprising a support pad 1 in contact with the ground, a central support block 15, and a connecting cylinder 3 disposed within the inner cavity of the cooling module. A mounting part 2 is fixedly connected to the top of the support pad 1. Both the inner cavities of the support pad 1 and the mounting part 2 are threadedly connected to connecting bolts 5, which are threadedly connected to the inner cavity of the connecting cylinder 3. A rigid skeleton ring 9 is fixedly connected to the inner cavity of the mounting part 2. Multiple support rods 11 are fixedly connected to the inner cavity of the rigid skeleton ring 9. A connecting ring 10, sleeved on the surface of the connecting bolts 5, is fixedly connected to the inner cavity of the mounting part 2. The surface of the connecting ring 10 is fixedly connected to the surface of the support rods 11. Through the combined support of the support pad 1 and the central support block 15, the radial support strength of the mounting part 2 is effectively improved, solving the problem of existing radiator pads being easily squeezed, deformed, and worn. To address issues such as cracking, the reliability of the radiator support pad is significantly improved, while also considering the overall NVH performance of the vehicle. The connecting cylinder 3 is installed below the cooling module, and then the collar 6 is fitted over the mounting part 2. The mounting part 2 and the connecting cylinder 3 are then threaded together using the threaded sleeve 13. At this point, the collar 6 is rotated to rotate the extension plate 7 to a horizontal angle. Then, the connecting cylinder 3, collar 6, and mounting part 2 are locked using the connecting bolt 5. After the mounting part 2 and support pad 1 are installed, the extension plate 7 is locked to the bottom of the cooling module using the locking bolt 8. This allows for quick and easy overall installation, is simple to operate, convenient to use, and securely fixed. When the cooling module moves, the extension plate 7 limits the movement distance, preventing radial gaps between structures and preventing large axial displacement that could cause cracking.

[0031] A collar 6 is slidably connected to the surface of the mounting part 2. One side of the collar 6 abuts against the bottom of the cooling module. An extension plate 7 is fixedly connected to one side of the collar 6. The surface of the extension plate 7 abuts against the bottom of the cooling module. During installation, a hole adapted to the connecting cylinder 3 is opened in the cooling module. Then, the connecting plate 4 is welded into the cooling module. Then, the connecting cylinder 3 is installed below the cooling module. Then, the collar 6 is fitted onto the top of the mounting part 2. Then, the mounting part 2 and the connecting cylinder 3 are threaded together by the threaded sleeve 13. At this time, the collar 6 is rotated to rotate the extension plate 7 to a horizontal angle.

[0033] A threaded sleeve 13 is fixedly connected to the inner cavity of the mounting part 2. The inner cavity of the threaded sleeve 13 is threadedly connected to the surface of the connecting cylinder 3. An elastic ring 14 that abuts against the surface of the threaded sleeve 13 is also fixedly connected to the inner cavity of the mounting part 2. During installation, a hole adapted to the connecting cylinder 3 is drilled in the cooling module. Then, the connecting plate 4 is welded into the cooling module. Next, the connecting cylinder 3 is installed below the cooling module. Then, the collar 6 is fitted onto the top of the mounting part 2. Finally, the mounting part 2 and the connecting cylinder 3 are threaded together using the threaded sleeve 13. At this point, rotating the collar 6 rotates the extension plate 7 to a horizontal angle. Then, the connecting cylinder 3, the collar 6, and the mounting part 2 are locked by the connecting bolt 5. After the mounting part 2 and the support pad 1 are installed, the extension plate 7 is locked to the bottom of the cooling module by the locking bolt 8. The middle support block 15 is installed below the cooling module. At this time, the locking bolt 8 on the surface of the extension plate 7 is inserted into the cavity 16. At this time, the top return spring 19 pushes the top block 20 to press against the bottom of the cooling module. When the cooling module shakes during operation, the top of the collar 6 abuts against the bottom of the cooling module. The extension plate 7 increases the contact area, and the middle support block 15 distributes the force evenly.

[0034] The connecting cylinder 3 is fixedly connected to the surface of the inner cavity of the cooling module by a connecting plate 4 that is welded to the inner cavity of the cooling module.

[0035] The bottom plate of the extension plate 7 is threaded with a locking bolt 8 that is threaded to the inner cavity of the cooling module. The top of the middle support block 15 is provided with a slot 16. The inner cavity of the slot 16 is adapted to the surface of the locking bolt 8, and the inner cavity of the slot 16 is provided with an elastic rubber pad. When the middle support block 15 is installed below the cooling module, the locking bolt 8 on the surface of the extension plate 7 is inserted into the slot 16. At this time, the top return spring 19 pushes the top block 20 to press against the bottom of the cooling module. When the cooling module shakes during operation, the top of the collar 6 abuts against the bottom of the cooling module. The extension plate 7 increases the contact area, and the middle support block 15 distributes the force evenly.

[0036] The inner cavity of the middle support block 15 is movably connected to the top block 20 through the movable groove 17. The inner cavity of the movable groove 17 is provided with a spring groove 18, and the inner cavity of the spring groove 18 is fixedly connected to a return spring 19. The top of the return spring 19 is fixedly connected to the bottom of the top block 20. When the middle support block 15 is installed below the cooling module, the locking bolt 8 on the surface of the extension plate 7 is inserted into the hollow groove 16. At this time, the top return spring 19 pushes the top block 20 to press against the bottom of the cooling module. When the cooling module shakes during operation, the top of the collar 6 abuts against the bottom of the cooling module. The contact area is increased by the extension plate 7. It can be supported individually or used in combination. It can be freely adjusted according to the usage and has a wide range of applications.

[0037] When the return spring 19 is in its initial state, the highest horizontal plane of the top block 20 is higher than the highest horizontal plane of the collar 6.

[0038] Four support pads 1 are provided and are evenly distributed around the cooling module. Two support blocks 15 are provided in the middle and abut against the two extension plates 7 respectively.

[0039] The support rods 11 are arranged in a ring array inside the rigid skeleton ring 9 and are curved rods.

[0040] The method of using this shock-absorbing pad includes the following steps:

[0041] Step 1: During installation, drill a hole in the cooling module that matches the connecting cylinder 3, then weld the connecting plate 4 into the cooling module, then install the connecting cylinder 3 below the cooling module, then put the collar 6 on top of the mounting part 2, and then thread the mounting part 2 and the connecting cylinder 3 together with the threaded sleeve 13. At this time, rotate the collar 6 to rotate the extension plate 7 to a horizontal angle, and then lock the connecting cylinder 3, collar 6 and mounting part 2 with the connecting bolt 5. After the mounting part 2 and the support pad 1 are installed, lock the extension plate 7 to the bottom of the cooling module with the locking bolt 8.

[0042] Step 2: Install the middle support block 15 below the cooling module. At this time, the locking bolt 8 on the surface of the extension plate 7 is inserted into the groove 16. The top return spring 19 pushes the top block 20 to press against the bottom of the cooling module. When the cooling module shakes during operation, the top of the collar 6 abuts against the bottom of the cooling module. The extension plate 7 increases the contact area, and the middle support block 15 distributes the force evenly. This solves the problem that soft pads can only withstand axial force and are insufficient in bearing radial force, which requires frequent replacement during use. Otherwise, it will lead to product aging and damage, short service life, and poor support capacity under high-intensity working conditions.
