Description

Technical Field

[0001] This utility model belongs to the field of design and development technology of green and environmentally friendly interior products for transportation vehicles, and specifically relates to an environmentally friendly composite fabric mat for transportation vehicle seats. Background Technology

[0002] Although most vehicles nowadays are equipped with air conditioning to cool the interior, there are strict regulations regarding when and under what circumstances air conditioning can be used in commercial vehicles such as buses and subways. This creates a situation where, during the transition from spring to summer and from summer to autumn, although the perceived temperature is relatively high, it is not yet at a level suitable for turning on the air conditioning. Therefore, the comfort level of passengers is relatively low during these periods.

[0003] Ice pads, also known as cooling pads, are common heat dissipation and cooling products. When used properly, they can last for about five years, making them sustainable and low-cost. During the aforementioned seasons, using ice pads on the seats of commercial vehicles effectively increases the cooling comfort for drivers and passengers. Improved comfort leads to more passengers choosing to travel in these vehicles during this season, naturally increasing economic benefits.

[0004] However, the use of ice pads also brings some practical problems: for example, after a day of operation, since many different passengers will have continuous close contact with the ice pads, cleaning staff need to disinfect and wipe the surface of the ice pads after the vehicles stop operating each day. This will gradually wear down the outer packaging layer of the ice pads, thereby increasing the risk of the active ingredients inside the ice pads volatilizing and spilling out, which is not conducive to the service life of the ice pads.

[0005] For example, some passengers who like to take advantage of small things will take the ice pads on the seats for themselves, which not only causes economic losses, but also directly affects the riding experience of subsequent passengers. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly fabric composite pad for vehicle seats, including an ice pad, which is composed of an inner cooling core material and an outer packaging layer for wrapping the cooling core material.

[0007] Two first straps extend outward from the top of the outer packaging layer. Each first strap has a first connecting ring fixedly connected to the end away from the outer packaging layer. Each first strap passes through the grab ring near the top of the seat back from front to back and locks the first connecting rings together with a padlock, thereby locking the ice pad to the seat (4).

[0008] The eco-friendly fabric bag, made of hydrophobic and breathable material, is fitted over the ice pad with its opening facing upwards. The bag opening has a zipper, which keeps the eco-friendly fabric bag from falling off the ice pad.

[0009] Preferably, the outer packaging layer is formed by thermally bonding two rectangular waterproof fabrics of the same specifications and dimensions together in a circumferential manner through the areas near the perimeter of each fabric. At the same time, several strip-shaped sealing areas are provided at intervals along the length of the outer packaging layer. The strip-shaped sealing areas extend along the width of the outer packaging layer. The strip-shaped sealing areas are also formed by thermally bonding corresponding areas on the two waterproof fabrics. The outer packaging layer is divided into several independent cavities for accommodating the cooling core material through these strip-shaped sealing areas. The top edge of the outer packaging layer, from which the first binding strap extends outward, extends along the width of the outer packaging layer.

[0010] As a preferred embodiment, a second strap extends outward from the top edge of each of the two side edges of the outer packaging layer. A second connecting ring is fixedly connected to the end of each second strap away from the outer packaging layer. Each second strap passes around the backrest from the side to the backrest and locks the first and second connecting rings together with a padlock.

[0011] As a preferred option, perforations are provided on the two side edges of the eco-friendly fabric bag at corresponding positions near the top opening of the bag, and the second tie extends out of the eco-friendly fabric bag through the corresponding perforations.

[0012] As a preferred option, each perforation is connected upwards to the bag opening on the body of the environmentally friendly fabric bag.

[0013] Preferably, when the distance between the two first straps is less than half the length of the top edge of the outer packaging layer along the length of the top edge of the outer packaging layer, the portion of the bag opening located outside the two first straps is set as a zipper, while the portion of the bag opening located between the two first straps is always set as an open opening.

[0014] Preferably, when the distance between the two first straps along the length of the top edge of the outer packaging layer is not less than half the length of the top edge of the outer packaging layer, the part of the bag opening located between the two first straps is set as a zipper, while the part of the bag opening located outside the two first straps is always set as an open.

Detailed Implementation

[0025] It should be noted that the terms "before" and "after" used in the description of this application refer to the appendix. Figure 4 , 8 In this context, "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] As shown in the attached figures, the environmentally friendly composite fabric mat for vehicle seats of this utility model first includes an ice mat 1. The ice mat 1 consists of an inner cooling core material 11 and an outer packaging layer 12 for wrapping the cooling core material 11. The cooling core material 11 is a water-rich hydrogel material with a long service life. The outer packaging layer 12 is formed by two rectangular waterproof fabrics of the same specifications and dimensions, facing each other and circumferentially heat-bonded together through the area near the perimeter of each fabric surface. At the same time, along the length of the outer packaging layer 12, a number of strip-shaped sealing areas 121 are evenly arranged at intervals. Each strip-shaped sealing area 121 extends along the width of the outer packaging layer 12, as shown in the attached figures. Figure 1 , 6 The strip-shaped sealing area 121 is also formed by thermally bonding corresponding strip areas on two waterproof fabrics together. The areas on the two waterproof fabrics that are not thermally bonded together are fitted together to form cavities for accommodating the cooling core material 11. Therefore, the outer packaging layer 12 is divided into several independent cavities by these strip-shaped sealing areas 121, as shown in the attached diagram. Figure 9 ;

[0027] The top edge of the outer packaging layer 12 is an edge extending along the width direction of the outer packaging layer 12. Two first binding straps 2 extend outwards symmetrically along the length direction of the outer packaging layer 12 based on its perpendicular line. The first binding straps 2 are nylon webbing. One end of the first binding strap 2 is firmly sewn face-to-face to the heat-composite area at the top of the outer packaging layer 12, and the other end passes through the first connecting ring 3 and is then firmly sewn face-to-face to the binding strap near that end to form a closed loop, thereby firmly connecting the first connecting ring 3. (See attached diagram.) Figure 1 , 6 ;

[0028] For a vehicle seat 4 with two symmetrical grab rings 411 near the top of the backrest 41, the two first straps 2 pass through the grab rings 411 one by one from front to back away from the outer packaging layer 12 along their respective length directions. Then, the two first connecting rings 3 are locked together by the padlock 5, thereby locking the ice pad 1 to the seat 4, as shown in the attached figure. Figure 5 At this time, the ice pad 1 covers the backrest 41 (by controlling the length of the first strap 2, after being locked by the padlock 5, the ice pad 1 starts to spread down along the backrest 41 from the grab ring 411, so as to cover the entire backrest 41 body as much as possible in the height direction).

[0029] Meanwhile, on the two side edges of the outer packaging layer 12, near the top edge, there are second binding straps 7 extending outward along the width direction of the outer packaging layer 12. Similarly, the second binding straps 7 are nylon webbing. One end of the second binding strap 7 is firmly sewn face-to-face to the heat-bonded area at the side edge of the outer packaging layer 12, and the other end passes through the second connecting ring 8 and is then firmly sewn face-to-face to the binding strap near that end to form a closed loop, thereby firmly connecting the second connecting ring 8, as shown in the attached diagram. Figure 1 , 6 ;

[0030] The two second straps 7, each extending along their respective lengths away from the outer packaging layer 12, wind from the side of the backrest 41 to the rear of the backrest 41. They are then secured together with the two first connecting rings 3 via padlocks 5, as shown in the attached diagram. Figure 5 (By controlling the length of the second strap 7, after being locked by the padlock 5, the ice pad 1 is pulled apart to both sides along its width direction by the two second straps 7, so as to avoid the ice pad 1 from folding on the surface of the backrest 41 and affecting the coverage area).

[0031] An eco-friendly fabric bag 6, made of hydrophobic and breathable material, fits over the ice pad 1 with its opening facing upwards. Perforations 62 are located on the two side edges of the eco-friendly fabric bag 6 near the top opening, respectively. Each perforation 62 connects upwards to the opening on the body of the eco-friendly fabric bag 6, as shown in the attached diagram. Figure 2 , 3 7. The second strap 7 extends out of the eco-friendly fabric bag 6 through the corresponding perforation 62.

[0032] Along the length of the top edge of the outer packaging layer 12, when the distance between the two first binding straps 2 (each first binding strap 2 has a width approximately one-eighth of the length of the top edge of the outer packaging layer 12, and the first binding strap 2 and the second binding strap 7 have the same width) is less than one-half the length of the top edge of the outer packaging layer 12 (as shown in the attached figure) Figure 6 The portions of the bag opening located outside the two first straps 2 are each equipped with a zipper 61, while the portion of the bag opening located between the two first straps 2 remains open (as shown in the attached image). Figure 7 );

[0033] Along the length of the top edge of the outer packaging layer 12, when the distance between the two first binding straps 2 is not less than half the length of the top edge of the outer packaging layer 12 (as shown in the attached figure) Figure 1 The portion of the bag opening between the two first straps 2 is equipped with a zipper 61, while the portion of the bag opening outside the two first straps 2 is always open (as shown in the attached document). Figure 2 , 3 ).

[0034] The spacing between the two first straps 2 is determined by the spacing between the two grab rings 411 on the backrest 41 that is compatible with the ice pad 1 (see attached). Figure 1 Ice pad 1 is compatible with the attached Figure 4 Backrest 41; Attached Figure 6 Ice pad 1 is compatible with the attached Figure 8 (Backrest 41);) But in either case, the zipper 61 keeps the eco-friendly fabric bag 6 from falling off the ice pad 1.

[0035] In the above technical solution, the ice pad 1 is locked to the seat 4 by the setting of the first connecting ring 3, the second connecting ring 8 and the padlock 5, which prevents it from being taken away by some passengers who are greedy for small gains; at the same time, for the convenience of operation and management, a through-lock padlock can be used (that is, only one key is needed to open all the padlocks 5 on one or even several vehicles); at the same time, the length and size of the first strap 2 and the second strap 7 are adapted to the structure of the backrest 41 to ensure the coverage effect of the ice pad 1 on the backrest 41 (this point has been described in detail in the above specific implementation method).

[0036] The ice pad 1 is covered with an environmentally friendly fabric bag 6, which is made of a hydrophobic and breathable fabric (similar to the fabric used in commercially available windbreakers). On one hand, it effectively blocks sweat from the passenger's body (especially during the transition from spring to summer and from summer to autumn, when passengers wear light summer clothing, and some passengers, particularly those who have just completed heavy physical labor, have their outer clothing visibly soaked with sweat), greatly reducing contact and contamination of the ice pad 1, thus being environmentally friendly. This eliminates the need for frequent disinfection and wiping of the ice pad 1, avoiding wear and tear on the waterproof outer packaging layer 12, and effectively preventing the loss of the active ingredients inside the ice pad 1, thereby extending its lifespan (although the ice pad 1 is not an expensive item, its cost is still significantly higher than the environmentally friendly fabric bag 6). Moreover, the environmentally friendly fabric bag 6 only needs to be replaced after each use, and the removed bags should be cleaned and reused.

[0037] The eco-friendly fabric bag 6 is designed to open and close via a zipper 61, and the perforation 62 on the body of the eco-friendly fabric bag 6 connects to the opening, allowing the eco-friendly fabric bag 6 to be disassembled and replaced without opening the padlock 5. This makes the operation convenient.

[0038] On the other hand, the fabric has good breathability, which has little impact on the passenger's perception of the cooling sensation of the ice pad 1.

[0039] Furthermore, considering that the ice pad 1 needs to be laid vertically against the backrest 41, the hydrogel material (cooling core material 11) inside will fall and accumulate in large quantities at the bottom of the ice pad 1 due to its own gravity, thus affecting the cooling sensation of the upper part of the ice pad 1. To address this, this solution divides the inner cavity of the outer packaging layer 12 into several independent cavities along its length (vertical direction) to accommodate the cooling core material 11, which facilitates the even distribution of the cooling core material 11 across the entire ice pad 1 (as shown in the attached diagram). Figure 9 This allows passengers to feel a cool sensation throughout their entire back.
