Description

Technical Field

[0001] This utility model relates to the field of foam technology, specifically to a shockproof foam base pad. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam has a series of characteristics such as light weight, elasticity, ease of use, flexibility, ultra-thin size, and reliable performance. It is generally used for the protection of valuable and fragile items. Some electronic products are often damaged to varying degrees due to impacts during transportation, causing losses to customers and merchants. Adding foam around electronic products can effectively reduce the impact force and greatly improve the protection of electronic products, which has led to the widespread use of foam. However, the shockproof performance of existing foam during use is relatively low.

[0003] Therefore, it is particularly important to design a shock-absorbing foam base pad to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing foam base pad to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shock-absorbing foam base pad includes a surface foam layer and a bottom foam layer. The top of the bottom foam layer is connected to multiple sets of equally spaced buffer strips. The buffer strips are composed of multiple sets of U-shaped ribs and V-shaped ribs. The top of the bottom foam layer, located between two sets of buffer strips, is connected to multiple sets of evenly distributed buffer pads. The buffer pads are composed of concave seats, elastic washers, and buffer heads.

[0007] As a preferred embodiment of this utility model, the top and bottom of the buffer assembly strip are respectively bonded to the inner sides of the surface foam layer and the bottom foam layer with foam adhesive.

[0008] As a preferred embodiment of this utility model, the U-shaped ribs and V-shaped ribs are distributed alternately, and the two are bonded together by foam adhesive.

[0009] As a preferred embodiment of this utility model, the bottom of the concave seat is bonded to the top surface of the bottom foam layer with foam adhesive, and the top of the buffer head is bonded to the bottom surface of the top foam layer with foam adhesive.

[0010] As a preferred embodiment of this utility model, the U-shaped rib, V-shaped rib, concave seat, and buffer head are all made of EVA foam.

[0011] In a preferred embodiment of this utility model, the elastic washer is sleeved on the outside of the buffer head, and the elastic washer is inserted into the inside of the concave seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a shock-absorbing foam base pad is designed to divide the originally integral foam pad into a composite structure of a surface foam layer and a bottom foam layer. Multiple sets of equally spaced buffer strips are incorporated between the two layers. These buffer strips, composed of U-shaped and V-shaped ribs, can reduce the impact and compression on items. The spaced arrangement of the U-shaped and V-shaped ribs enhances the securing effect of the items, preventing movement and misalignment during transportation, thus ensuring product integrity and safety. The cavities between the U-shaped and V-shaped ribs provide excellent cushioning, reducing vibration and impact on the items. On the top surface of the bottom foam layer, between two adjacent sets of buffer strips, multiple sets of buffer pads composed of concave seats, elastic washers, and buffer heads are added. This increases the support and reinforcement between the surface and bottom foam layers. During compression, the buffer heads interact with the concave seats, while the central elastic washers provide cushioning, creating pressure between the buffer heads and concave seats and absorbing vibration and impact, preventing loosening. The overall structure significantly increases the shock-absorbing capability of the foam base pad. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0024] A shock-absorbing foam base pad includes a surface foam layer 1 and a bottom foam layer 2. Multiple sets of equally spaced buffer strips 3 are connected to the top of the bottom foam layer 2, and multiple sets of evenly distributed buffer pads 4 are connected to the top of the bottom foam layer 2 and at the position between two sets of buffer strips 3.

[0025] The top and bottom of the buffer assembly strip 3 are respectively bonded to the inner sides of the surface foam layer 1 and the bottom foam layer 2 with foam adhesive.

[0026] In this embodiment, please refer to Figure 3 The buffer strip 3 is composed of multiple sets of U-shaped ribs 301 and V-shaped ribs 302, which can reduce the impact and compression of items.

[0027] The U-shaped ribs 301 and V-shaped ribs 302 are distributed alternately, which can improve the function of fixing items and prevent movement and misalignment during transportation, thereby ensuring the integrity and safety of the product. The two are bonded together with foam adhesive. The U-shaped ribs 301 and V-shaped ribs 302, as well as the concave seat 401 and the buffer head 403 are all made of EVA foam, which has high strength and good cushioning.

[0028] In this embodiment, please refer to Figure 4 The buffer pad 4 is composed of a concave seat 401, an elastic washer 402 and a buffer head 403, which can increase the support and reinforcement between the surface foam layer 1 and the bottom foam layer 2.

[0029] The bottom of the concave seat 401 is bonded to the top surface of the bottom foam layer 2 with foam adhesive, and the top of the buffer head 403 is bonded to the bottom surface of the top foam layer 1 with foam adhesive. The elastic washer 402 is sleeved on the outside of the buffer head 403 and inserted inside the concave seat 401. During compression, the buffer head 403 and the concave seat 401 interact, and the elastic washer 402 in the middle can play a buffering role, so that a certain pressure is generated between the buffer head 403 and the concave seat 401, and it can absorb vibration and impact force, thereby preventing loosening. The overall structure greatly increases the shock absorption capability of the foam base pad.

[0030] The working process of this utility model is as follows: The originally integrated foam pad is divided into a composite structure of a surface foam layer 1 and a bottom foam layer 2. Multiple sets of equally spaced buffer strips 3 are arranged between the two layers. The buffer strips 3 are composed of U-shaped ribs 301 and V-shaped ribs 302, which can reduce the impact and compression of items. The spaced arrangement of the U-shaped ribs 301 and V-shaped ribs 302 enhances the fixation of items, preventing movement and misalignment during transportation, thereby ensuring the integrity and safety of the product. The cavity between the U-shaped ribs 301 and V-shaped ribs 302 provides good cushioning, thus reducing the impact on items. To mitigate vibrations and impacts, multiple sets of buffer pads 4, consisting of concave seats 401, elastic washers 402, and buffer heads 403, are added to the top surface of the bottom foam layer 2 between two adjacent sets of buffer pads 3. This increases the support and reinforcement between the top foam layer 1 and the bottom foam layer 2. During compression, the buffer heads 403 interact with the concave seats 401, while the elastic washers 402 in the middle act as buffers, generating pressure between the buffer heads 403 and the concave seats 401. This absorbs vibrations and impacts, preventing loosening. The overall structure significantly increases the shock absorption capability of the foam pad.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
