Description

Technical Field

[0001] This utility model relates to the field of seat fabric technology, and in particular to a seat fabric with breathable and antibacterial functions. Background Technology

[0002] Seat fabric is a functional textile material used in car seats. Its core lies in the simultaneous improvement of air circulation efficiency and inhibition of microbial growth through structural design and material combination, thereby providing a comfortable and healthy contact experience for drivers and passengers. With the increasing requirements for environmental protection and comfort in car interiors, the problems of stuffiness and odor caused by sweat residue and bacterial growth due to insufficient breathability of traditional seat fabrics are becoming increasingly prominent. Therefore, a seat fabric with breathable and antibacterial functions is needed.

[0003] Early breathable and antibacterial fabrics used a process of coating the base fabric with antibacterial agents or adding inorganic antibacterial particles to the blended fabric. The base fabric provided basic support and breathable channels, while the antibacterial agents achieved antibacterial effects through ion release or photocatalysis. However, the coating layer easily clogged the fiber pores, reducing breathability, and the blended particles were easily shed due to friction, resulting in poor antibacterial durability and biosafety risks. To solve this problem, existing fabrics use a multi-layer composite structure with an antibacterial functional layer woven from ultra-fine denier fibers on the surface, a mesh breathable base material in the middle, and an antibacterial fabric at the bottom. This avoids the problem of reduced breathability caused by direct clogging. However, in actual use, because the functional layers cannot be replaced individually when damaged, the entire fabric becomes unusable after wear and tear, failing to meet the needs of users. Utility Model Content

[0006] The fixing mechanism includes multiple base plates. One side of each base plate is fixedly connected to the front and rear ends of the bottom of a corresponding support rod. A positioning post is fixedly connected to the top of each base plate. A wedge groove is formed on the upper part of the outer wall of each positioning post. Rotating blocks are rotatably connected to the front and rear sides of the top of each support rod. A groove is formed at one end of each rotating block. A wedge is slidably connected inside each groove. A sliding rod is fixedly connected to one end of each wedge. A spring is provided on the outer wall of each sliding rod. One end of each spring is fixedly connected to one end of a corresponding wedge. The other end of each spring is fixedly connected to the inner wall of a corresponding groove. A sliding groove is formed on the top of each rotating block. An unlocking component is provided inside each sliding groove.

[0007] As a further description of the above technical solution:

[0008] A breathable layer is provided on the upper inner side of the outer cover, and an antibacterial layer is provided on the lower inner side of the outer cover. Positioning holes are provided at the four corners of the top of the breathable layer and the antibacterial layer, and the positions of the multiple positioning holes correspond to the corresponding positioning posts.

[0009] As a further description of the above technical solution:

[0010] The tensioning mechanism includes two guide rods. The front and rear ends of the two guide rods are fixedly connected to the front and rear sides of the inner wall of the corresponding limiting groove, respectively. Sliders are slidably connected to the front and rear sides of the outer wall of the two guide rods. A second spring is provided in the middle of the outer wall of the two guide rods. The front and rear ends of the two second springs are fixedly connected to one side of the corresponding slider, respectively. Rotating rods are rotatably connected to the upper middle part of the other side of the multiple sliders. The other ends of the multiple rotating rods are rotatably connected to the left and right sides of the breathable layer, respectively.

[0011] As a further description of the above technical solution:

[0012] The unlocking component includes multiple pull rods, one side of each pull rod is slidably connected to the inner wall of a corresponding groove, one end of each slide rod passes through a corresponding groove and is fixedly connected to one side of the corresponding pull rod, and a sliding plate is fixedly connected to the top of each pull rod.

[0013] As a further description of the above technical solution:

[0014] The top of the outer cover is provided with a wear-resistant layer, and the top of the wear-resistant layer has multiple conical holes.

[0015] As a further description of the above technical solution:

[0016] The top four sides of the outer cover are fixedly connected with female stickers, and the bottom four sides of the wear-resistant layer are fixedly connected with female stickers. The positions of the multiple female stickers correspond to the positions of the corresponding female stickers.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, after aligning the positioning holes at the four corners of the breathable layer and the antibacterial layer with the positioning post at the bottom, the positioning post passes through the positioning hole. The rotating block is rotated so that the wedge block contacts the outer wall of the positioning post. The wedge block is squeezed and shrinks into the groove. After the wedge block coincides with the wedge groove on the outer wall of the positioning post, the wedge block is rebounded by the spring and engages with the wedge groove. The rotating block fixes the breathable layer and the antibacterial layer from above to prevent them from falling off, making it easy to replace the breathable layer and the antibacterial layer.

[0023] 2. In this utility model, when the breathable layer is subjected to pressure, multiple rotating rods exert lateral tension on the breathable layer. The pressure causes the rotating rods on both sides to rotate, and the corresponding sliders move in the grooves. The elastic force of the second spring acts as a buffer and provides resistance to the movement of the sliders. The resistance affects the rotating rods in the opposite direction, so that the rotating rods apply longitudinal tensile force to the breathable layer when rotating. This ensures that the breathable layer is not closed by the tensile force of the rotating rods while under pressure, thus maintaining the breathable function. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 5 and Figure 6This utility model provides an embodiment of a seat fabric with breathable and antibacterial functions, including an outer cover 1. Support rods 2 are fixedly connected to the bottom left and right sides of the inner side of the outer cover 1. Fixing mechanisms 3 are provided on the top of the front and rear sides of the two support rods 2. The fixing mechanisms 3 are used to fix the breathable layer 6 and the antibacterial layer 7. Limiting grooves 4 are formed on the top of the two support rods 2, and tensioning mechanisms 5 are provided inside the two limiting grooves 4. The fixing mechanism 3 includes multiple base plates 301, one side of each base plate 301 being connected to the bottom of a corresponding support rod 2. The front and rear ends of the unit are fixedly connected. Positioning posts 302 are fixedly connected to the top of multiple base plates 301. A wedge groove 303 is formed on one side of the upper middle part of the outer wall of each positioning post 302. The wedge groove 303 is used to engage with a wedge block 306. Rotating blocks 304 are rotatably connected to the front and rear sides of the top of the two support rods 2. A groove 305 is formed at one end of each rotating block 304, providing installation space inside. A wedge block 306 is slidably connected inside each groove 305, engaging with the wedge groove 303. The multiple wedge blocks 306... Each of the 6 components has a slide rod 307 fixedly connected to one end. Each slide rod 307 has a spring 308 on its outer wall, which resets the wedge block 306. One end of each spring 308 is fixedly connected to one end of the corresponding wedge block 306, and the other end of each spring 308 is fixedly connected to the inner wall of the corresponding groove 305. Each of the rotating blocks 304 has a groove 309 on its top, which provides the range of motion for the pull rod 3101. Each groove 309 contains an unlocking component 310. The unlocking component 310 is used to disengage the wedge block 306 from the wedge groove 303. The unlocking component 310 includes multiple pull rods 3101. One side of each pull rod 3101 is slidably connected to the inner wall of the corresponding slide groove 309. One end of each slide rod 307 passes through the corresponding groove 305 and is fixedly connected to one side of the corresponding pull rod 3101. A sliding plate 3102 is fixedly connected to the top of each pull rod 3101. The pull rods 3101 serve as a connector, allowing the sliding plate 3102 to drive the slide rod 307 through the pull rods 3101.

[0034] Specifically, the breathable layer 6 and the antibacterial layer 7 are embedded inside the cover, and the positioning holes 8 of the breathable layer 6 and the antibacterial layer 7 are aligned with the positioning post 302 at the bottom. Then, the breathable layer 6 and the antibacterial layer 7 are moved downwards so that the positioning post 302 passes through the positioning hole 8 for initial fixation. Then, the rotating block 304 is rotated so that the wedge 306 in the groove 305 of the rotating block 304 contacts the outer wall of the positioning post 302. After being squeezed, the wedge 306 retracts into the groove 305, and at the same time, the spring is compressed. Under the action of the wedge 306, the slide rod 307 pushes the pull rod 3101 and the sliding plate 3102 to move. When the rotating block 304 rotates to a specific angle, the wedge 306 and the positioning post 302 are aligned. 2. The wedge grooves 303 on the outer wall coincide, and the wedge block 306 engages with the wedge groove 303 under the action of the spring rebound force, thereby fixing the rotating block 304. At the same time, the slide rod 307 drives the sliding plate 3102 to move together through the pull rod 3101. At this time, the rotating block 304 fixes the breathable layer 6 and the antibacterial layer 7 from above to prevent them from falling off. When it is necessary to remove the breathable layer 6 and the antibacterial layer 7, push the sliding plate 3102, and drive the slide rod 307 to move through the pull rod 3101. The slide rod 307 then pushes the wedge block 306 to disengage from the wedge groove 303 and release the lock. Finally, rotate the rotating block 304 to one side to release the fixation of the breathable layer 6 and the antibacterial layer 7 for easy replacement.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The tensioning mechanism 5 includes two guide rods 501. The front and rear ends of the two guide rods 501 are fixedly connected to the front and rear sides of the inner wall of the corresponding limiting groove 4, respectively. Slider 502s are slidably connected to the front and rear sides of the outer wall of the two guide rods 501. The sliders 502s are limited and guided by the guide rods 501s. Springs 503s are provided in the middle of the outer wall of the two guide rods 501s. The springs 503s play a buffering role. The front and rear ends of the two springs 503s are fixedly connected to one side of the corresponding slider 502, respectively. The upper middle part of the other side of the multiple sliders 502s is rotatably connected. A rotating rod 504 is connected to the outer cover 1, which stretches the breathable layer 6. The other ends of the multiple rotating rods 504 are respectively rotatably connected to the left and right sides of the breathable layer 6. The breathable layer 6 is provided in the upper middle part of the inner side of the outer cover 1. The breathable layer 6 is used to maintain good breathability. The antibacterial layer 7 is provided in the lower middle part of the inner side of the outer cover 1. The antibacterial layer 7 uses natural antibacterial materials to inhibit the generation of mold and odor. Positioning holes 8 are provided at the four corners of the top of the breathable layer 6 and the antibacterial layer 7. The positions of the multiple positioning holes 8 are respectively corresponding to the positioning posts 302.

[0036] Specifically, when the breathable layer 6 is subjected to pressure, it undergoes plastic deformation, causing the vents to be squeezed and closed. At this time, multiple rotating rods 504 exert a lateral pulling force on the breathable layer 6. Simultaneously, the pressure causes the rotating rods 504 on both sides to rotate. During the rotation of the rotating rods 504, the corresponding sliders 502 move within the grooves 309. The elastic force of the second spring 503 acts as a buffer and provides resistance to the movement of the sliders 502. The resistance affects the rotating rods 504 in the opposite direction, increasing the distance between the ends of the two rotating rods 504 on the front and rear sides connected to the breathable layer 6. This allows the rotating rods 504 to apply a longitudinal tensile force to the breathable layer 6 during rotation. Through this tensile action, the vents of the breathable layer 6 do not close due to the tensile action of the rotating rods 504 while under pressure, thus maintaining the breathability.

[0037] Reference Figure 1 and Figure 3 The top of the outer cover 1 is provided with a wear-resistant layer 9, which is used to withstand surface friction. The top of the wear-resistant layer 9 has multiple conical holes 10. The top four sides of the outer cover 1 are fixedly connected with female stickers 11, and the bottom four sides of the wear-resistant layer 9 are fixedly connected with female stickers 12. The female stickers 12 and the female stickers 11 are bonded together to connect the wear-resistant layer 9 to the outer cover 1. The positions of the multiple female stickers 11 correspond to the positions of the corresponding female stickers 12.

[0038] Specifically, the top wear-resistant layer 9 is used for direct contact and to withstand friction. The tapered holes 10 on the surface are small at the top and large at the bottom. The difference in hole diameter blocks large particles of impurities without affecting gas flow. When the wear-resistant layer 9 is connected to the female sticker 11 at the top of the outer cover 1 through the bottom female sticker 12, it is convenient to replace the wear-resistant layer 9 when it is damaged.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The outer cover 1 has a cover opening 13 on the front side, and a zipper 14 is fixedly connected to the inside of the cover opening 13. A cloth strip 15 is fixedly connected to the upper middle part of the front right end of the outer cover 1, and a bolt head 16 is fixedly connected to the bottom of the cloth strip 15. A bolt groove shell 17 is fixedly connected to the lower middle part of the front right end of the outer cover 1.

[0040] Specifically, by pulling the zipper 14, the opening 13 of the cover can be opened, which makes it convenient to replace the internal breathable layer 6 and antibacterial layer 7. After the zipper 14 is closed, the plug 16 at one end of the cloth tape 15 is inserted into the plug groove shell 17. The cloth tape 15 protects the zipper 14 and prevents the head of the zipper 14 from opening accidentally.

[0041] Working principle: The device places the breathable layer 6 and antibacterial layer 7 inside the cover, then aligns the positioning holes 8 at the four corners of the breathable layer 6 and antibacterial layer 7 with the positioning post 302 at the bottom and moves downwards, so that the positioning post 302 passes through the positioning holes 8. Then, the rotating block 304 is rotated, so that the wedge 306 in the groove 305 of the rotating block 304 contacts the outer wall of the positioning post 302. Subsequently, the wedge 306 is squeezed and retracts into the groove 305, and at the same time, the spring 308 is squeezed and retracted. Simultaneously, the sliding rod 307 is driven by the action of the wedge 306 to move the pull rod 3101 and the sliding plate 3102. When the rotating block 304 rotates to a certain angle, the wedge 306 and the wedge groove 303 on the outer wall of the positioning post 302 are aligned. After closing, the wedge 306 is rebounded by the spring, locking the wedge 306 into the wedge groove 303, thus fixing the rotating block 304. At the same time, the sliding rod 307 drives the pull rod 3101 and the sliding plate 3102 to move together. At this time, the rotating block 304 fixes the breathable layer 6 and the antibacterial layer 7 from above to prevent them from falling off. When it is necessary to remove the breathable layer 6 and the antibacterial layer 7, the sliding plate 3102 is pushed, causing the sliding plate 3102 to move through the pull rod 3101 and drive the sliding rod 307 to move. Then the sliding rod 307 drives the wedge 306 to move, causing the wedge 306 to disengage from the wedge groove 303 and release the lock. Then the rotating block 304 is rotated to the side, thus releasing the breathable layer 6 and the antibacterial layer 7 from the lock for easy replacement.

[0042] Furthermore, when the breathable layer 6 is subjected to pressure, it will undergo plastic deformation, causing the vent holes to close. At this time, the multiple rotating rods 504 on both sides exert a lateral pulling effect on the breathable layer 6. Simultaneously, the pressure causes the rotating rods 504 on both sides to rotate. As the rotating rods 504 rotate, they drive the corresponding sliders 502 to slide inside the slide groove 309. At this time, the elastic force of the second spring 503 causes the sliders 502 to be resisted, which in turn affects the rotating rods 504, causing the ends of the two rotating rods 504 on the front and rear sides connected to the breathable layer 6 to move away from each other. This allows the rotating rods 504 to exert a longitudinal stretching effect on the breathable layer 6 when rotating. When the vent holes are subjected to pressure, the stretching effect of the rotating rods 504 on the breathable layer 6 opens the vent holes, preventing them from closing due to plastic deformation and affecting breathability.
