Abstract
Description
Technical Field
[0001] This invention belongs to the field of synthetic leather structural design, and particularly relates to a high-efficiency breathable synthetic leather. Background Technology
[0002] Synthetic leather is an important component of the plastics industry and is widely used in various sectors of the national economy. It is one of the earliest developed sectors in China's plastics industry and has since been widely applied in many industries, particularly in the decoration of bags, shoes, clothing, vehicles, and furniture, where it has gained increasing market recognition. Currently, synthetic leather is used as seat cushions to improve comfort and perceived quality. However, when used as seat cushions, its poor breathability, especially in summer, leads to a less comfortable experience for users. Therefore, it is necessary to improve the breathability of synthetic leather. Furthermore, after prolonged use and pressure, the middle of the synthetic leather structure tends to sag, resulting in poor structural support, an unsightly appearance, and potential deformation and damage. Therefore, it is necessary to upgrade the existing synthetic leather structure to improve its breathability and heat dissipation when used as seat cushions, while also preventing the central sagging issue to maintain long-term aesthetics and integrity. Summary of the Invention
[0003] To address the shortcomings of the existing technology, the present invention provides a highly efficient breathable synthetic leather with good breathability and structural support.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A high-efficiency breathable synthetic leather includes a synthetic leather surface layer, an upper pressure layer, a lower positioning layer, a support bottom layer, extension guide rods, floating support blocks, a side telescopic layer, and a telescopic spring. The lower side of the synthetic leather surface layer is connected to the upper pressure layer. The lower side positioning layer is connected below the upper pressure layer. A pressure-relief cavity is provided between the upper pressure layer and the lower positioning layer. The upper pressure layer and the lower positioning layer are connected around their perimeters by the side telescopic layer. The support bottom layer is installed below the lower positioning layer. A flow-guiding cavity is provided between the lower positioning layer and the support bottom layer. Multiple extension guide rods are evenly installed on the lower side of the upper pressure layer, and the multiple extension guide rods are located within the pressure-relief cavity. A floating support block is installed on the lower side of each extension guide rod; multiple ventilation holes are evenly opened on the lower positioning layer; the floating support blocks at the lower end of the extension guide rod are respectively connected to the ventilation holes; multiple telescopic springs are evenly installed on both sides of the upper pressure layer and the lower positioning layer. The telescopic springs press upward against the upper pressure layer and the synthetic leather surface layer, and cause the floating support blocks to close and abut against the ventilation holes. When the synthetic leather surface layer is compressed, the synthetic leather surface layer and the upper pressure layer move downward, the telescopic springs are 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 away from the ventilation hole and press against the upper side of the support bottom layer.
[0005] Furthermore, multiple guide rods are evenly provided at the lower ends of both sides of the upper pressure layer; multiple 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.
[0006] Furthermore, the floating support block and the ventilation holes on the lower positioning layer both have a tapered structure that is smaller at the top and larger at the bottom.
[0007] Furthermore, the minimum diameter of the vent hole is greater than the diameter of the extension guide rod.
[0008] Furthermore, multiple air vents are evenly formed on the upper pressure layer.
[0009] Furthermore, the synthetic leather surface layer is made of polyurethane material.
[0010] Furthermore, the supporting bottom layer, the upper pressure layer, and the lower positioning layer are thermoplasticized from polypropylene resin.
[0011] Furthermore, the side stretchable layer is made of flexible non-woven fabric; the side stretchable layer has a stretchable and foldable structure.
[0012] Furthermore, the supporting bottom layer and the lower positioning layer are fixedly connected by multiple support strips.
[0013] The beneficial effects of this invention are as follows: 1. This invention features a built-in upper pressure layer and a lower positioning layer, with a pressure-reducing cavity between them. When a user sits on the surface, the synthetic leather surface layer is compressed, causing the synthetic leather surface layer and the upper pressure layer to move downwards. This compresses the telescopic spring, causing the extension guide rod and the floating support block to move downwards. The extension guide rod passes through the vent hole and pulls the floating support block downwards, disengaging it from the vent hole and pressing against the upper surface of the support layer. Thus, stable pressure is achieved through the support of the floating support block. Simultaneously, the floating support block... The vent holes are separated, allowing them to be connected. This creates a ventilation channel from bottom to top, consisting of a flow-guiding cavity, vent holes, a pressure-resistant cavity, and breathable holes. This greatly improves breathability. When the synthetic leather surface layer is not under pressure, the telescopic spring presses upward against the upper pressure layer and the synthetic leather surface layer, supporting the entire structure and preventing structural deformation caused by sagging. At the same time, the floating support block closes upward against the vent holes, thus sealing the pressure-resistant cavity and preventing dust and other contaminants from entering and making cleaning difficult later. The structure is flexible and convenient to use.
[0014] 2. This invention designs two ventilation channels. First, the upper pressure layer and the lower positioning layer are connected around their perimeter by a side stretch layer made of non-woven fabric. This allows the pressure cavity between the upper pressure layer and the lower positioning layer to have a certain degree of air permeability, forming the first ventilation channel. At the same time, the air passage formed from bottom to top by the guide cavity, the vent hole, the pressure cavity, and the vent hole constitutes the second ventilation channel. Thus, the air permeability of this invention is greatly enhanced. Attached Figure Description

[0020] The invention will now be described in further detail with reference to the accompanying drawings.
[0021] like Figures 1 to 5As shown, a high-efficiency breathable synthetic leather includes a synthetic leather surface layer 1, an upper pressure layer 2, a lower positioning layer 3, a support bottom layer 4, extension guide rods 5, floating support blocks 6, a side telescopic layer 7, and a telescopic spring 8. The lower side of the synthetic leather surface layer 1 is connected to the upper pressure layer 2. The lower side positioning layer 3 is connected below the upper pressure layer 2. A pressure cavity 21 is provided between the upper pressure layer 2 and the lower positioning layer 3. The upper pressure layer 2 and the lower positioning layer 3 are connected around their perimeter by the side telescopic layer 7. The support bottom layer 4 is installed below the lower positioning layer 3. A flow guiding cavity 31 is provided between the lower positioning layer 3 and the support bottom layer 4. Multiple extension guide rods 5 are evenly installed on the lower side of the upper pressure layer 2, and the multiple extension guide rods 5 are located within the pressure cavity 21. A floating support block 6 is installed on the lower side of each of the extension guide rods 5; multiple ventilation holes 32 are evenly opened on the lower positioning layer 3; the floating support blocks 6 at the lower end of the extension guide rods 5 are respectively connected to the ventilation holes 32; multiple telescopic springs 8 are evenly installed on both sides of the upper pressing layer 2 and the lower positioning layer 3. The telescopic springs 8 press the upper pressing layer 2 and the synthetic leather surface layer 1 upward, and make the floating support blocks 6 close and abut against the ventilation holes 32. When the synthetic leather surface layer 1 is compressed, the synthetic leather surface layer 1 and the upper pressing layer 2 move downward, the telescopic springs 8 are compressed, the extension guide rods 5 and the floating support blocks 6 move downward, the extension guide rods 5 pass through the ventilation holes 32 and drive the floating support blocks 6 downward to disengage from the ventilation holes 32 and press against the upper side of the support bottom layer 4.
[0022] like Figures 1 to 5 As shown, in order to improve the stability of the synthetic leather surface layer 1 and the upper pressure layer 2 moving up and down, a plurality of guide rods 22 are evenly provided at the lower ends of both sides of the upper pressure 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 into the guide cylinders 33.
[0023] like Figures 1 to 5 As shown, in order to facilitate the pressure sealing of the floating support block 6 and the vent hole 32, the floating support block 6 and the vent hole 32 on the lower positioning layer 3 are both tapered structures with a smaller top and a larger bottom.
[0024] like Figures 1 to 5 As shown, to further improve air permeability, the minimum diameter of the vent 32 is larger than the diameter of the extension guide rod 5. Furthermore, a plurality of vent holes 23 are uniformly formed on the upper pressure layer 2.
[0025] like Figures 1 to 5As shown, to improve structural stability, the synthetic leather surface layer 1 is further made of polyurethane material. Furthermore, the supporting bottom layer 4, the upper pressure layer 2, and the lower positioning layer 3 are thermoplasticized from polypropylene resin. Furthermore, the side stretch layer 7 is made of flexible non-woven fabric; the side stretch layer 7 has a stretchable and foldable structure. Furthermore, the supporting bottom layer 4 and the lower positioning layer 3 are fixedly connected by multiple support strips 9.
[0026] This invention features a built-in upper pressure layer 2 and a lower positioning layer 3, with a pressure cavity 21 between them. When a user sits on the pressure, the synthetic leather surface layer 1 is compressed, causing the synthetic leather surface layer 1 and the upper pressure layer 2 to move downwards. The telescopic spring 8 is compressed, and the extension guide rod 5 and the floating support block 6 move downwards. The extension guide rod 5 passes through the vent hole 32 and drives the floating support block 6 downwards, disengaging from the vent hole 32 and pressing against the upper surface of the support layer 4. Thus, stable pressure is achieved through the support of the floating support block 6. Simultaneously, the floating support block 6 and... The vent 32 is separated, allowing it to be open, thus forming a ventilation channel from bottom to top consisting of the flow guiding cavity 31, the vent 32, the pressure cavity 21, and the air vent. This greatly improves the breathability. When the synthetic leather surface layer 1 is not under pressure, the telescopic spring 8 presses upward against the upper pressure layer 2 and the synthetic leather surface layer 1, supporting the entire structure and preventing structural deformation. At the same time, the floating support block 6 closes upward against the vent 32, thus sealing the pressure cavity 21 and preventing dust and other contaminants from entering and making cleaning difficult later. The structure is flexible and convenient to use.
[0027] This invention designs two ventilation channels. First, the upper pressure layer 2 and the lower positioning layer 3 are connected around their perimeter by a side stretch layer 7, which is made of non-woven fabric. This allows the pressure cavity 21 between the upper pressure layer 2 and the lower positioning layer 3 to have a certain degree of air permeability, forming the first ventilation channel. At the same time, the ventilation channel formed from bottom to top by the guide cavity 31, the vent 32, the pressure cavity 21, and the vent is the second ventilation channel. Thus, the air permeability of this invention is greatly enhanced.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
