Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1 to 4, according to one aspect of the present disclosure, there is provided an insulation mat for a vehicle, including a surface insulation layer 1, wherein an insulation mesh 4 formed of an electric heating material is attached to an outer surface of the surface insulation layer 1.

Namely, on the basis of heat insulation, the sound insulation net 4 is added, as shown in fig. 4, the sound insulation net 4 is of a porous structure, so that the sound wave propagation of the vehicle noise is gradually attenuated, and the purposes of sound insulation and sound absorption are achieved; in addition, the sound-proof net 4 can be made of an electric heating material, so that the sound-proof net 4 can also play a role in heating after being electrified. And the heating of the vehicle can be automatically switched on or off according to the actual requirement of the vehicle. For example, in winter, under the condition of low temperature, in order to meet the normal working temperature of the engine, the sound insulation net 4 can heat the vehicle, and the vehicle heating speed is accelerated. The electric heating material can be a semiconductor material, and an insulating layer 6 can be additionally arranged outside to insulate the charged sound insulation net 4 from the outside.

In addition, in order to further enhance the noise absorption, in the present embodiment, as shown in fig. 3, the heat insulating mat for a vehicle further includes a sound absorbing layer 3 located on the surface heat insulating layer 1.

Like this, utilize sound absorbing layer 3 can absorb the noise of conduction, through the dual function of sound insulation net 4 and sound absorbing layer 3, can play isolated and absorptive effect to the noise, can reduce the noise of conducting in the car.

In other words, the heat insulating pad for the vehicle integrates multiple functions of heat insulation, sound absorption and real-time heating, and greatly improves riding comfort of passengers.

Specifically, in the present embodiment, the sound-absorbing layer 3 may be a polyester fiber sound-absorbing plate. The material has the advantages of good sound absorption performance, certain heat insulation performance, environmental friendliness, no toxicity, high impact resistance and stable performance, and can fully absorb noise transmitted to the interior of a vehicle.

The thickness of the heat insulating mat for a vehicle may be 20mm to 30mm, and the thickness of the sound absorbing layer 3 may be 8mm to 12 mm. Namely, under the premise of meeting the requirements of absorbing and isolating noise, the vehicle can avoid occupying too much space in the vehicle, and the comfort in the vehicle is ensured.

In order to further enhance noise insulation, in the present embodiment, a sound insulation layer 2 is further connected between the surface heat insulation layer 1 and the sound absorption layer 3. Namely, the sound absorption layer 3 is combined to form a double noise elimination barrier, so that the comfort of passengers in the vehicle is ensured.

As the name implies, sound insulation is relative to two spaces, and the main function is to block sound from one space to the other space, preventing noise interference. As shown in fig. 3, in order to sufficiently insulate noise, in the present embodiment, the soundproof layer 2 may further include a polyurethane layer 21 and an epdm layer 22, and the epdm layer 22 is connected to the sound absorption layer 3. Namely, the double sound insulation material structure of polyurethane material (PUR) and Ethylene Propylene Diene Monomer (EPDM) is adopted, and the thickness of the two layers of sound insulation structures is different in order to avoid the coincidence effect of the two layers of sound insulation structures and weaken the sound insulation effect. Therefore, the noise is fully isolated and blocked, and the noise is prevented from being transmitted into the vehicle to cause discomfort of passengers. Wherein, the polyurethane material can be the hard bubble body, forms the obturator structure, isolated sound to have thermal-insulated performance simultaneously concurrently, with 1 combined action of surface insulating layer, make the thermal-insulated performance increase.

In the present embodiment, the polyester fiber sound-absorbing sheet described above may be heat-rivet-welded to the soundproof layer 2. Can support the deformation with sound absorbing layer 3 through the head of riveter, as shown in fig. 3, sound absorbing layer 3 after the deformation is supported and is formed with recess 31, namely, dotted line position in the figure supports presses to puigging 2, the high temperature of riveter head melts puigging 2 heating this moment for puigging 2 and sound absorbing layer 3 interconnect together, recess 31 through this kind of connected mode formation can also have the sound absorbing effect in sound absorbing hole in addition, thereby further increase sound absorbing layer 3's sound absorbing effect.

The hot riveting welding is a permanent fixing and assembling method which is simple, reliable and high in cost performance, can be used for multi-point riveting and fixing, does not need to add any adhesive, solvent, filler and fastener, does not consume a large amount of energy, and is environment-friendly, energy-saving, efficient and firm in connection.

Since the cost of the epdm rubber material is higher than that of the polyurethane material, in this embodiment, the thickness ratio between the polyurethane layer 21 and the epdm rubber layer 22 may be 6:1 to 7: 1. The ethylene propylene diene monomer material has relatively high cost, but the limited thickness can realize remarkable sound insulation effect. Therefore, the thickness of the ethylene propylene diene monomer rubber layer 22 can be 2 mm-2.5 mm, and the sound insulation effect of the polyurethane layer 21 can be increased along with the increase of the thickness, so that the cost can be saved in the range of the increase of the thickness, and the good noise reduction and sound insulation effect can be achieved.

Wherein, the surface thermal insulation layer 1 can be an aluminum foil layer. The aluminum foil material can reflect heat and play a role in isolating heat, the thickness of the common aluminum foil layer can be 0.1-0.2 mm, only a thin layer is needed, the space in the vehicle is not occupied, and the good heat insulation effect can be realized.

In the present embodiment, the surface heat insulating layer 1 and the sound insulating layer 2 are integrally bonded to each other by foam bonding. That is, the sound insulation layer 2 may be a hard foam material among the above-described polyurethane materials, and after the surface heat insulation layer 1 and the sound insulation layer 2 are heated and baked by a mold, the hard foam material has an adhesion and sound insulation effect, and the sound insulation layer 2 and the surface heat insulation layer 1 are integrally adhered and molded. That is, the aluminum foil layer and the ethylene propylene diene monomer layer are respectively connected together through the polyurethane foaming material, and finally the aluminum foil layer, the ethylene propylene diene monomer layer and the ethylene propylene diene monomer layer are connected into a whole.

According to another aspect of the present disclosure, there is also provided a vehicle including the above vehicle heat insulating mat. Therefore, the noise can be effectively reduced, the noise is reduced, the comfort of the vehicle is improved, and when the temperature in the vehicle needs to be increased, the vehicle component heating system can be communicated to heat the vehicle component heating system.

In order to realize the heating function of the vehicle heat insulating mat, the vehicle further includes a vehicle ECU (vehicle-mounted computer, i.e., vehicle controller) and a temperature detection device 5, wherein the vehicle ECU is electrically connected to the sound insulating net 4 and the temperature detection device 5, respectively, to receive the temperature signal of the temperature detection device 5 and control the heating sound insulating net 4 according to the temperature signal.

That is, the temperature of the vehicle is detected in real time by the temperature detection device 5, for example, the vehicle component may be an engine compartment component requiring a heating function, and at this time, the target temperature range may be set to be 0 to 90 degrees, and when the vehicle is lower than the minimum value of the target temperature, the sound insulation network 4 is connected to convert the electric energy into heat energy, so that the heat energy is dissipated to the vehicle, and thus, the vehicle can be heated; above this maximum value of the target temperature, the sound-insulating screen 4 is disconnected, and the sound-insulating screen 4 only remains responsible for sound insulation. The temperature detection means 5 may be a temperature sensor and the controller may be a controller of the vehicle itself. As shown in fig. 1, an engine compartment 7 with a heat insulating mat for a vehicle is shown.
