The film composite layer includes a transparent TPU sheet and a BEMIS PU film, and the transparent TPU sheet and the BEMIS PU film are heat-bonded together.

The shock-absorbing cotton layer includes EVA cotton. the

The main shell layer of soft rubber includes 1-6 soft rubber blocks, and the shape of the soft rubber blocks includes triangular, quadrangular or pentagonal with arc edges. the

The shock-absorbing cotton layer includes 1-6 EVA cotton sheets, and the shape of the EVA cotton sheets includes triangular, quadrangular or pentagonal with curved edges. the

The protective pad and the cloth are heat-bonded together. the

The edges of the soft rubber blocks are butted or overlapped. the

Realize the method of the present invention is:

A: First, mold the soft rubber block into the desired shape through the injection molding process;

 Punch the knife mold made of EVA cotton with laser cutting into the required shape;

Cut the TPU sheet and BEMIS PU film into specific size;

Then use the "high-frequency hot stamping" process to fuse the TPU sheet and the BEMIS PU film into a composite sheet;

B: Put the soft rubber block upside down on the pre-manufactured metal mold;

Put the washed EVA cotton into the soft rubber block;

Put the prefabricated TPU sheet and BEMIS PU film composite sheet on the top layer;

Using a high-frequency blanching process, with a specific temperature and energy, the entire periphery of the composite sheet and the bottom soft rubber block are fully fused to form a protective pad;

C: The protective pad is punched with a knife mold made by laser cutting to become a complete formed protective pad;

D: Put the fully formed protective pad upside down on the pre-manufactured metal mold;

Put the required fabric on a specific position;

Using a high-frequency hot-blanking process, with a specific temperature and energy, the fully formed protective pad and fabric are fully fused around the entire perimeter to become a complete protective pad on the fabric.

The technical solution of the present invention also includes protective pads for garments, such as outerwear, trousers, underwear, underwear, footwear and caps. The structure of the protective pad is the same as above. Corresponding to the vulnerable parts of the human body. the

The protective pad can also be used on other objects that need to protect the human body. the

The invention has the beneficial effects of good impact resistance, simple structure, low cost, convenient and comfortable use, and the like. the

Detailed ways

The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:

As shown in Fig. 1, the protection pad 1 and the cloth 2 are combined into one through a mold and high-frequency blanching. The protective pad 1 is composed of a soft rubber main shell layer, a shock-absorbing cotton layer and a film composite layer. The soft rubber main shell layer is composed of 1-6 soft rubber blocks 11, the shock-absorbing cotton layer is composed of 1-6 EVA cotton 12, and the film composite layer 13 is composed of TPU sheet 131 and BEMIS PU film 132.

The shapes of the soft rubber block 11 and the EVA cotton 12 are consistent, being triangular or quadrilateral or pentagonal with arc edges, etc., also in the same quantity. the

Example 1

Make protective pads.

1. First, mold the soft rubber block into the desired shape through the injection molding process (4 different shapes and sizes of triangles with an arc edge);

2. Punch the piece of EVA cotton into the required shape (same as the soft rubber block) with a knife mold made by laser cutting;

3. Cut the TPU sheet and BEMIS PU film into specific size;

4. Then use the "high-frequency hot stamping" process to fuse the TPU sheet and the BEMIS PU film into a composite sheet;

5. Put the soft rubber block upside down on the pre-manufactured metal mold "as the bottom layer";

6. Put the washed EVA cotton into the soft rubber block (it is the middle shock-absorbing cotton layer);

7. Put the prefabricated TPU sheet and BEMIS PU film composite sheet on the top layer (top layer);

8. Using the "high-frequency hot ironing" process, with a specific temperature and energy, the entire periphery of the composite sheet and the bottom soft rubber block are fully fused to form a protective pad;

9. The protective pad is edged with a knife mold made by laser cutting to become a "completely formed protective pad".

10. Butt the edges of 4 "completely formed protection pads" and place them upside down on the pre-manufactured metal mold;

11. Put the required fabric in a specific position;

12. Using the "high-frequency hot ironing" process, with a specific temperature and energy, the "completely formed protective pad" and the fabric are fully fused around the entire perimeter to become a complete protective pad on the fabric.

Example 2

After the protective pad is ironed with fabric and then made into clothes, the protective pad corresponds to the parts that are prone to collision and injury (such as joints, etc.), and its soft rubber block and built-in shock-absorbing cotton can directly greatly reduce the shock generated during impact Injury due to impact. The purpose is to prevent people from being injured by direct or indirect collisions during sports.
