Description

Technical Field

[0001] The utility model relates to the technical field of automobile appliances, in particular to a heat-insulating and flame-retardant foot pad with a ceramic function. Background Art

[0002] Flame retardants, also known as fireproofing agents, are additives that increase the flame resistance, self-extinguishing properties, or smoke suppression of flammable or combustible materials. They are important additives for fine chemical products and synthetic composite materials. By adding flame retardants to materials, they change some of the material's inherent properties, effectively preventing combustion or slowing the spread of fire. Materials are the pillars of modern science and technology and social development, and competition in modern high-tech depends heavily on the development of materials science. After the 1950s, with the development of the polymer industry, human production and living standards continued to improve. One of the key indicators of this improvement is the widespread use of synthetic fibers, plastics, and rubber, three major synthetic materials, in various production and living areas, including transportation, construction materials, electronics, and household goods.

[0003] With the continuous advancement of automobiles, new energy vehicles are becoming increasingly common. While bringing convenience to people's lives, they also pose corresponding safety risks. The batteries of most new energy vehicles are installed in the undercarriage. When the power supply shorts or generates heat, the heat is first transmitted to the interior of the vehicle. Currently, there is a lack of flame-retardant materials to address these sudden safety hazards. At the same time, the use of car floor mats is increasing, playing an increasingly important role in the automotive industry. The various types of floor mats currently on the market can improve the aesthetics of the cab, but their functionality is poor and they are inconvenient to replace and clean. Furthermore, traditional flame-retardant materials will incinerate and fall off in flames or high-temperature environments, resulting in poor flame retardancy and safety issues. Summary of the Invention

[0004] In order to solve certain technical problems existing in the prior art, the purpose of this application is to provide a heat-insulating and flame-retardant foot pad with ceramic function, which can solve the safety hazards caused by the lack of corresponding flame-retardant materials on the bottom of the car in the prior art to deal with emergencies, and make the tram safer during use.

[0005] To solve the above existing technical problems, this application adopts the following technical solutions:

[0006] A heat-insulating and flame-retardant foot pad with ceramic function includes a foot pad main body, the surface of the foot pad main body is provided with an anti-slip and dirt-retaining pad, the foot pad main body includes a leather layer, a heat-insulating layer, a fire-proof layer and a shaping layer, the heat-insulating layer is filled with a heat-insulating polyolefin composite material, the fire-proof layer is made of a ceramic flame-retardant composite material, and the lower surface of the heat-insulating layer is interwoven with the fire-proof layer.

[0008] Preferably, fixing parts connected to the foot pad body are provided around the anti-slip and dirt-receiving pad.

[0009] Preferably, the anti-slip dirt-receiving pad adopts a hollow structure in the middle.

[0010] Preferably, a plurality of pins are provided at the bottom of the anti-slip raised layer, and the pins are inserted into the anti-slip dirt-receiving pad.

[0011] Preferably, a plurality of longitudinally arranged support rods are provided in the anti-slip dirt-receiving mat, and the anti-slip dirt-receiving mat is shaped by the support rods.

[0012] Preferably, the support rod is provided with an outwardly protruding V-shaped convex ring, and one side of the pin is provided with a V-shaped groove, and the pin is positioned by cooperating with the V-shaped convex ring through the V-shaped groove.

[0013] Preferably, a positioning layer is provided on the lower surface of the shaping layer, and the positioning layer is made of burred cloth or silicone cloth.

[0014] Preferably, the leather layer is made of artificial leather material, and the lower surface of the leather layer is bonded and fixed to the upper surface of the heat insulation layer.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The shaping layer provides the floor mat with a certain degree of shape support, allowing it to fit perfectly under the vehicle. The fireproof and heat-insulating layers are flexible at room temperature, facilitating cleaning and installation. When exposed to open flames or high temperatures, the heat-insulating layer slows heat transfer to the interior, while the fireproof layer forms a ceramic-like structure upon burning, rapidly hardening and isolating the material from heat and combustible gases. The fireproof layer, with its ceramic properties, provides both heat and fire insulation, preventing fires from igniting the vehicle interior and providing more time for escape. This reduces the potential safety hazards posed by the vehicle's power supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 3 As shown, a heat-insulating and flame-retardant foot pad with ceramic function includes a foot pad body 1, and a non-slip and dirt-retaining pad 2 is provided on the surface of the foot pad body 1. The foot pad body 1 includes a leather layer 4, a heat-insulating layer 5, a fire-proof layer 6 and a shaping layer 7. The heat-insulating layer 5 is filled with a heat-insulating polyolefin composite material, and the fire-proof layer 6 is made of a ceramic flame-retardant composite material. The lower surface of the heat-insulating layer 5 and the fire-proof layer 6 are interwoven.

[0029] The foot mat body 1 is laid on the bottom of the car in a fully enclosed manner. The shaping layer 7 can give the foot mat a certain shape support and can completely fit the bottom of the car. The fireproof layer 6 and the heat insulation layer 5 have a certain flexibility at room temperature, which is convenient for cleaning and installation. When encountering open flames or high temperatures, the heat insulation layer 5 will delay the transfer of heat to the inside, and the fireproof layer 6 can form a ceramic-like body when burned, which can achieve rapid hardening and isolate the transfer of heat and combustible gases. The fireproof layer 6 has the characteristics of a ceramic body, which plays a role in heat insulation and fire isolation, prevents fire inside the car, and reduces the sudden safety hazards caused by the car's power supply device; and the lower surface of the heat insulation layer 5 and the upper surface of the fireproof layer 6 are interwoven, which can form an interwoven overall structure between the two to avoid separation during practical use.

[0030] A further improvement is that a detachable anti-skid raised layer 9 is provided on the surface of the anti-skid dirt-receiving mat 2 ; and fixing parts 3 connected to the foot pad body 1 are provided around the anti-skid dirt-receiving mat 2 .

[0031] The anti-skid dirt-collecting layer is provided with a detachable raised structure on its surface, which can increase the surface roughness and can also be removed and cleaned regularly. At the same time, the anti-skid dirt-collecting mat 2 is connected to the foot mat body 1 by fixing parts 3, making it convenient to disassemble and clean the entire anti-skid dirt-collecting layer in daily life.

[0032] A further improvement is that the anti-slip dirt-collecting mat 2 adopts a middle hollow structure; the middle hollow structure can not only improve the elasticity, but also collect dirt in the middle hollow structure, making the environment inside the car better and facilitating later flushing.

[0033] A further improvement is that a plurality of pins 13 are provided at the bottom of the anti-slip raised layer 9, and the pins 13 are inserted into the anti-slip dirt-receiving mat 2; a plurality of longitudinally arranged support rods 11 are provided in the anti-slip dirt-receiving mat 2, and the anti-slip dirt-receiving mat 2 is shaped by the support rods 11.

[0034] A number of downwardly protruding pins 13 are formed at the bottom of the anti-slip raised layer 9, and the anti-slip raised layer 9 can be inserted into the anti-slip dirt-receiving mat 2 through the pins 13, thereby playing a role of relative positioning, and preventing the anti-slip raised layer 9 from sliding during use. At the same time, a number of longitudinally arranged rubber support rods 11 are formed in the anti-slip dirt-receiving mat 2. The anti-slip dirt-receiving mat 2 can play a shaping role through the support rods 11, and avoid the anti-slip dirt-receiving mat 2 from collapsing after being subjected to force and the problem of being difficult to recover, and also provide effective rigid support for the anti-slip dirt-receiving mat 2.

[0035] Based on the above technical solution, it is further improved that the support rod 11 is provided with an outwardly protruding V-shaped convex ring 12, and one side of the pin 13 is provided with a V-shaped groove 14, and the pin 13 is positioned by cooperating with the V-shaped convex ring 12 through the V-shaped groove 14.

[0036] When the pin 13 is inserted into the anti-slip dirt-collecting pad 2, the V-shaped groove 14 faces the outward-protruding V-shaped convex ring 12 on the support rod 11, so that a certain snap-fit ​​structure is formed between the two, avoiding the problem of frequent separation of the anti-slip convex layer 9 during use.

[0037] A further improvement is that a positioning layer 8 is provided on the lower surface of the shaping layer 7, and the positioning layer 8 is made of burred cloth or silicone cloth.

[0038] The positioning layer 8 is made of burr cloth or silicone cloth structure, which can make the foot mat body 1 fit better with the interior of the car when it is placed in the car.

[0039] A further improvement is that the leather layer 4 is made of artificial leather material, the lower surface of the leather layer 4 is bonded and fixed to the upper surface of the heat insulation layer 5; the lower surface of the fireproof layer 6 and the upper surface of the shaping layer 7 are bonded and formed; the production cost is lower and the production is more convenient.

[0040] A further improvement is that the heat-insulating polyolefin composite material is compounded from wollastonite powder and polypropylene; and the ceramic flame-retardant composite material is compounded from ethylene-vinyl acetate, zinc borate, magnesium hydroxide, and phosphate glass powder.

[0041] The heat insulation layer 5 and the fireproof layer 6 in the structure of the foot pad body 1 are respectively made of a flame retardant composite material, which can make the flame retardant grade of the foot pad body 1 reach V-0 level, and the heat insulation and flame retardant performance is better.

[0042] A further improvement is that the outer edges of the leather layer 4, the heat insulation layer 5, the fireproof layer 6 and the shaping layer 7 are provided with a stitching edging 10, through which the layers of the foot pad body 1 can be formed into a complete whole, avoiding the phenomenon of external contour separation during use.

[0043] When using the heat-insulating and flame-retardant foot pad, the anti-slip and dirt-collecting pad 2 is connected to the foot pad main body 1 by using the fixing part 3. At the same time, the lower layer of the anti-slip and dirt-collecting pad 2 uses a rubber bottom layer to increase the friction between the foot pad and the leather layer 4 to prevent arbitrary movement. A support rod 11 is provided inside to prevent collapse. The interior can be used to collect dirt, and the anti-slip raised layer 9 on the surface can be taken out and cleaned regularly; the fireproof layer 6 is used to increase the flame-retardant effect, the heat-insulating layer 5 is used to isolate the transfer of heat and combustible gas, and the shaping layer 7 is used to fix the shape of the fireproof layer 6. The support rod 11 is used to make a cavity inside, which can make dust and dirt on the sole fall into the cavity. At the same time, the supporting structure can be connected to the anti-slip raised layer 9 layers.

[0044] During cleaning, the anti-skid dirt-collecting mat 2 is connected by the fixing part 3 and can be taken out as a whole. At the same time, the anti-skid raised layer 9 on the surface of the anti-skid dirt-collecting mat 2 is connected by the support rod 11 and can also be disassembled for cleaning. The dust and dirt collected in the internal cavity can be cleaned centrally. The fireproof layer 6 is made of a composite material prepared from ethylene-vinyl acetate, zinc borate, magnesium hydroxide, and phosphate glass powder. When encountering high temperature or open flame, it can form a ceramic layer to prevent further internal combustion. The heat insulation layer 5 is made of a composite material prepared from wollastonite powder and polypropylene, which can prevent heat from further transferring to the interior of the vehicle, providing people with more time to escape.

[0045] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
