Description

Technical Field

[0001] The present invention belongs to the field of synthetic leather structure design, and particularly relates to a highly breathable synthetic leather. Background Art

[0002] Synthetic leather is an important part of the plastics industry and is widely used in various industries of the national economy. It is an industry that developed relatively early in the Chinese plastics industry. So far, it has been widely used in many industries, especially in the decoration fields of luggage, shoes, clothing, vehicles, and furniture, and has increasingly been affirmed by the market. For existing seats, in order to improve the use comfort and grade, synthetic leather is used as a seat cushion. When used as a seat cushion, especially in summer, its air permeability is poor, resulting in a poor experience for the user. Therefore, it is necessary to improve the air permeability of synthetic leather. At the same time, when synthetic leather is used, after long-term sitting pressure, the middle of the entire structure will collapse downward, and the structural supportability is poor, which is not beautiful and will cause deformation and damage to the structure. Therefore, it is necessary to upgrade and transform the existing synthetic leather structure to improve the air ventilation and heat dissipation performance when synthetic leather is used as a seat cushion, and at the same time avoid the drawback of the middle of the entire structure collapsing downward to maintain long-term beauty and integrity. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the problem solved by the present invention is to provide a highly breathable synthetic leather with good air permeability and good structural supportability.

[0004] To solve the above problems, the technical solutions adopted by the present invention are as follows: An efficient breathable synthetic leather, comprising a synthetic leather surface layer, an upper pressing layer, a lower positioning layer, a supporting bottom layer, extending guide rods, floating supporting blocks, side expansion layers, and expansion springs; the lower side of the synthetic leather surface layer is connected to the upper pressing layer; the lower side of the upper pressing layer is connected to the lower positioning layer; a pressing cavity is provided between the upper pressing layer and the lower positioning layer; the peripheries of the upper pressing layer and the lower positioning layer are connected by side expansion layers; the supporting bottom layer is installed on the lower side of the lower positioning layer; a flow guiding cavity is provided between the lower positioning layer and the supporting bottom layer; a plurality of extending guide rods are evenly installed on the lower side of the upper pressing layer, and the plurality of extending guide rods are located in the pressing cavity; a floating supporting block is installed on the lower side of each of the extending guide rods; a plurality of ventilation holes are evenly formed in the lower positioning layer; the floating supporting blocks at the lower ends of the extending guide rods respectively pass through the ventilation holes; a plurality of expansion springs are evenly installed on the front and rear sides of both sides of the upper pressing layer and the lower positioning layer, and the expansion springs press the upper pressing layer and the synthetic leather surface layer upward, and make the floating supporting blocks close and abut upward against the ventilation holes. When the synthetic leather surface layer is pressed, the synthetic leather surface layer and the upper pressing layer move downward, the expansion springs are compressed, the extending guide rods and the floating supporting blocks move downward, the extending guide rods pass through the ventilation holes and drive the floating supporting blocks to move downward and separate from the ventilation holes and abut against the upper side surface of the supporting bottom layer.

[0005] Further, a plurality of guide rods are evenly provided at the lower ends of both sides of the upper pressing layer; a plurality of guide cylinders are evenly provided at the upper ends of both sides of the lower positioning layer; the guide rods are slidably inserted into the guide cylinders up and down.

[0006] Further, both the floating supporting blocks and the ventilation holes on the lower positioning layer are in a tapered structure with a smaller upper part and a larger lower part.

[0007] Further, the minimum diameter of the ventilation holes is greater than the diameter of the extending guide rods.

[0008] Further, a plurality of ventilation holes are evenly formed in the upper pressing layer.

[0009] Further, the synthetic leather surface layer is made of polyurethane material.

[0010] Further, the supporting bottom layer, the upper pressing layer, and the lower positioning layer are thermoplastically formed from polypropylene resin.

[0011] Further, the side expansion layer is made of flexible non-woven fabric material; the side expansion layer is in a telescopic folding structure.

[0012] Further, the supporting bottom layer and the lower positioning layer are fixedly connected by a plurality of supporting bars.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention designs an internal upper pressing layer and a lower positioning layer. A pressing cavity is arranged between the upper pressing layer and the lower positioning layer. When a user sits and presses, when the synthetic leather surface layer is pressed, the synthetic leather surface layer and the upper pressing layer move downward, the telescopic spring is compressed, the extension guide rod and the floating support block move downward. The extension guide rod passes through the ventilation hole and drives the floating support block to move downward and separate from the ventilation hole to press against the upper side of the support bottom layer. In this way, stable pressing is achieved through the support of the floating support block. At the same time, the floating support block is separated from the ventilation hole, making the ventilation hole conduct, so as to form a ventilation channel from bottom to top for the diversion cavity, ventilation hole, pressing cavity, and ventilation hole, greatly improving the air permeability. When the synthetic leather surface layer is not pressed, the telescopic spring presses upward against the upper pressing layer and the synthetic leather surface layer, supporting the entire structure to avoid the drawback of structural deformation due to sagging. At the same time, the floating support block moves upward to closely abut against the ventilation hole, closing the pressing cavity to prevent dust and the like from entering, which is difficult to clean later. The structure is flexible and convenient to use.

[0014] 2. The present invention designs two ventilation channels. First, the peripheries of the upper pressing layer and the lower positioning layer are connected by a side telescopic layer made of non-woven fabric material. In this way, the pressing cavity between the upper pressing layer and the lower positioning layer has a certain air permeability, forming the first ventilation channel. At the same time, the ventilation channel formed from bottom to top by the diversion cavity, ventilation hole, pressing cavity, and ventilation hole is the second ventilation channel. In this way, the air permeability of the present invention is greatly enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

A pressing cavity 21 is provided between the upper pressing layer 2 and the lower positioning layer 3. The peripheries of the upper pressing layer 2 and the lower positioning layer 3 are connected by side telescopic layers 7. The supporting bottom layer 4 is installed on the lower side of the lower positioning layer 3. A diversion cavity 31 is provided between the lower positioning layer 3 and the supporting bottom layer 4. A plurality of extending guide rods 5 are evenly installed on the lower side of the upper pressing layer 2, and the plurality of extending guide rods 5 are located in the pressing cavity 21. A floating supporting block 6 is installed on the lower side of each of the extending guide rods 5. A plurality of ventilation holes 32 are evenly formed in the lower positioning layer 3. The floating supporting blocks 6 at the lower ends of the extending guide rods 5 are respectively inserted through the ventilation holes 32. A plurality of telescopic springs 8 are evenly installed on the front and back sides of both sides of the upper pressing layer 2 and the lower positioning layer 3. The telescopic springs 8 upwardly press the upper pressing layer 2 and the synthetic leather surface layer 1, and make the floating supporting blocks 6 upwardly and hermetically abut against the ventilation holes 32. When the synthetic leather surface layer 1 is pressed, the synthetic leather surface layer 1 and the upper pressing layer 2 move downward, the telescopic springs 8 are compressed, the extending guide rods 5 and the floating supporting blocks 6 move downward, the extending guide rods 5 pass through the ventilation holes 32 and drive the floating supporting blocks 6 to downwardly disengage from the ventilation holes 32 and abut against the upper side surface of the supporting bottom layer 4.

[0022] As Figures 1 to 5 shown, in order to improve the stability of the up and down movement of the synthetic leather surface layer 1 and the upper pressing layer 2, further, a plurality of guide rods 22 are evenly provided at the lower ends of both sides of the upper pressing layer 2. A plurality of guide cylinders 33 are evenly provided at the upper ends of both sides of the lower positioning layer 3. The guide rods 22 are slidably inserted up and down in the guide cylinders 33.

[0023] As Figures 1 to 5 shown, in order to facilitate the pressing and closing of the floating supporting blocks 6 and the ventilation holes 32, further, both the floating supporting blocks 6 and the ventilation holes 32 on the lower positioning layer 3 are in a tapered structure with a smaller upper part and a larger lower part.

[0024] As Figures 1 to 5 shown, in order to improve the air permeability, further, the minimum diameter of the ventilation holes 32 is greater than the diameter of the extending guide rods 5. Further, a plurality of ventilation holes 23 are evenly formed in the upper pressing layer 2.

[0025] As Figures 1 to 5As shown, in order to improve the stability of the structure, further, the synthetic leather surface layer 1 is made of polyurethane material. Further, the supporting bottom layer 4, the upper side pressure layer 2, and the lower side positioning layer 3 are thermoplasticized by polypropylene resin. Further, the side telescopic layer 7 is made of flexible non-woven fabric material; the side telescopic layer 7 is a telescopic folding structure. Further, the supporting bottom layer 4 and the lower side positioning layer 3 are fixedly connected by a plurality of support bars 9.

[0026] The present invention is designed with a built-in upper pressure-receiving layer 2 and a lower positioning layer 3, and a pressure-receiving cavity 21 is arranged between the upper pressure-receiving layer 2 and the lower positioning layer 3. When the user sits and presses, the synthetic leather surface layer 1 is pressed, the synthetic leather surface layer 1 and the upper pressure-receiving layer 2 move downward, the telescopic spring 8 is compressed, the extending guide rod 5 and the floating support block 6 move downward, the extending guide rod 5 passes through the vent hole 32 and drives the floating support block 6 to break away from the vent hole 32 and press against the upper side of the supporting bottom layer 4, so that stable pressure is achieved through the support of the floating support block 6, and at the same time, the floating support block 6 and The vent holes 32 are separated so that the vent holes 32 are connected, thus forming a ventilation channel from bottom to top of the guide cavity 31, the vent holes 32, the pressure cavity 21, and the air holes, which greatly improves the breathability. When the synthetic leather surface layer 1 is not under pressure, the telescopic spring 8 presses the upper pressure layer 2 and the synthetic leather surface layer 1 upward to support the entire structure and avoid the disadvantage of structural deformation. At the same time, the floating support block 6 is closed upward and abuts against the vent holes 32, so that the pressure cavity 21 is closed to prevent dust from entering and being difficult to clean later. The structure is flexible and convenient to use.

[0027] The present invention designs two ventilation channels. First, the upper pressure layer 2 and the lower positioning layer 3 are connected on all sides by the side expansion layer 7. The side expansion layer 7 is made of non-woven fabric material, so that the pressure cavity 21 between the upper pressure layer 2 and the lower positioning layer 3 has a certain air permeability, forming a first ventilation channel. At the same time, the ventilation channel formed by the guide cavity 31, the vent 32, the pressure cavity 21, and the vent from bottom to top is the second ventilation channel. In this way, the air permeability of the present invention is greatly enhanced.
