Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 , Figure 5 and Figure 6 , the present invention provides a technical solution: a polyurethane buffer pad with high load-bearing capacity and durability, including a waterproof outer frame 1 and a buffer mechanism 4. A first buffer layer 5 is provided inside the waterproof outer frame 1. The buffer mechanism 4 is connected to one side of the first buffer layer 5. Waterproof coatings 2 are connected to the sides of the energy absorption pad 3 and the first fixing layer 9 that are away from each other. The edge of the waterproof coating 2 is fixedly connected to the waterproof outer frame 1. The materials of the waterproof coating 2 and the waterproof outer frame 1 are both silicone.

[0025] During specific implementation, since most polyurethane buffer pads may often be in a humid environment, the surface of the polyurethane buffer pad is eroded by moisture, resulting in softening and a decrease in strength. The outer surface of the polyurethane buffer pad can be protected by the waterproof outer frame 1 and the waterproof coating 2 to prevent moisture from entering the interior of the polyurethane buffer pad, improving the durability of the polyurethane buffer pad.

[0026] Please refer to Figures 2-7, a support spring 7 is provided inside the buffer mechanism 4. A second buffer layer 6 is connected to the side of the buffer mechanism 4 away from the first buffer layer 5. The buffer mechanism 4 includes a buffer block 401, a cushion block 402, and a cushion groove 403. One side of the first buffer layer 5 is fixedly connected to the cushion block 402. The support spring 7 is located in the built-in groove of the cushion block 402. A cushion groove 403 is provided on the side of the second buffer layer 6 close to the cushion block 402. The cushion groove 403 is connected to the cushion block 402. Buffer blocks 401 are annularly distributed in the middle of the second buffer layer 6. Absorbing pads 3 are fixedly connected to the sides of the first buffer layer 5 and the second buffer layer 6 that are away from each other. A second fixing layer 10 is fixedly connected to the side of the absorbing pad 3 away from the second buffer layer 6. A first fixing layer 9 is provided on the side of the second fixing layer 10 away from the absorbing pad 3. An energy absorption mechanism 8 is connected between the second fixing layer 10 and the first fixing layer 9. The energy absorption mechanism 8 includes an energy absorption groove 801 and an energy absorption block 802. Equally spaced energy absorption grooves 801 and energy absorption blocks 802 are provided on the adjacent sides of the second fixing layer 10 and the first fixing layer 9. The cross-sectional shapes of the energy absorption groove 801 and the energy absorption block 802 are both triangular. The energy absorption groove 801 and the energy absorption block 802 are cross-distributed. The materials of the first buffer layer 5, the second buffer layer 6, the first fixing layer 9, and the second fixing layer 10 are all polyurethane. The absorbing pad 3 is provided in a honeycomb shape.

[0027] During specific implementation, since most polyurethane buffer pads have fewer layers and poor cushioning performance, the bearing capacity of the polyurethane buffer pad will be limited and deformation is likely to occur. The bearing force can be dispersed by multiple absorbing pads 3. The cushion block 402, the support spring 7, and the cushion groove 403 reinforce and buffer the four corners of the polyurethane buffer pad, and several buffer blocks 401 reinforce and buffer the middle of the polyurethane buffer pad. The second fixing layer 10 and the first fixing layer 9 disperse the pressure received to the energy absorption blocks 802 and the energy absorption grooves 801, so that the pressure can be buffered multiple times. Through the setting of multiple cushion layers, the cushioning performance and bearing capacity of the polyurethane buffer pad are improved.

[0028] Working principle: When using this high-bearing-capacity and durable polyurethane buffer pad, first, the bearing force is dispersed by multiple absorbing pads 3. At the same time, the buffer mechanism 4 and the energy absorption mechanism 8 buffer and disperse the pressure multiple times. The waterproof outer frame 1 and the waterproof coating 2 protect the outer surface of the polyurethane buffer pad to prevent moisture from entering the inside of the polyurethane buffer pad, improving the bearing capacity and durability of the polyurethane buffer pad. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
