[0050] The present application relates to a vehicle, which includes a heating device. A vehicle body floor and other components of the vehicle together form a passenger compartment, and the interior space of the passenger compartment is used to accommodate drivers and passengers. When the outdoor temperature is low, the temperature of the interior space of the passenger compartment is also low, which makes the driving or riding experience of the drivers and passengers poor.

[0051] The cover of the heating device of the present application shields at least a portion of the hollow area of ​​the vehicle body floor to heat the vehicle body floor, thereby increasing the temperature of the interior space of the passenger compartment and improving the comfort of the driver and passengers.

[0052] See also Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of the exploded structure of a heating device 100 provided in one embodiment of the present application is shown; Figure 2 A schematic diagram of the structure of a heating device 100 provided in one embodiment of the present application is shown; Figure 3 A schematic structural diagram of a heating device 100 provided in another embodiment of the present application is illustrated.

[0053] The heating device 100 provided in the present application includes a cover body 10, a heating element 20 and a vehicle body floor 90. The cover body 10 is plate-shaped and includes a first plate plane 101. The first plate plane 101 is the surface of the cover body 10 facing the vehicle body floor 90. The cover body 10 is fixedly connected to the vehicle body floor 90.

[0054] Specifically, in one embodiment, the cover body 10 contacts the vehicle body floor 90, and the cover body 10 shields the hollow area 91 of the vehicle body floor 90. The heating device 100 generates heat when it works, and the heat is conducted to the vehicle body floor 90 through the first plate plane 101, and then conducted from the vehicle body floor 90 to the passenger compartment to increase the temperature in the passenger compartment.

[0055] In addition, in another embodiment, the vehicle body floor 90 is provided with a hollow area 91, the cover 10 covers at least part of the hollow area 91 and / or is embedded in the hollow area 91, and the first plate plane 101 faces the passenger compartment. The heating device 100 generates heat when it works, and the heat can be directly conducted to the space in the passenger compartment through the first plate plane 101, thereby increasing the temperature in the passenger compartment. In this embodiment, the cover 10 is embedded in the hollow area 91 of the vehicle body floor 90, which can improve the fixing reliability between the cover 10 and the vehicle body floor 90, and can also improve the heating effect of the cover 10 on the passenger compartment and improve the heating efficiency.

[0056] The cover 10 of the heating device 100 of the present application shields the hollow area 91 of the vehicle body floor 90 to facilitate heat conduction. At the same time, the vehicle body floor 90 is located at the bottom of the passenger compartment. When the heating device 100 heats the passenger compartment, the temperature in the passenger compartment can be evenly increased, thereby improving the comfort of the driver and passengers. At the same time, the heat of the heating device 100 of the present application can also be conducted to other components to heat other components in the vehicle that need to be heated, thereby improving the utilization rate of heat by integrating the heating device 100. In addition, the cover 10 shielding the hollow area 91 of the vehicle body floor 90 can also achieve lightweighting of the vehicle body floor 90 and reduce costs.

[0057] Specifically, in one embodiment, see Figure 1 and Figure 2The vehicle body floor 90 is provided with a hollow area 91, the cover body 10 at least partially shields the hollow area 91 and / or is embedded in the hollow area 91, and the cover body 10 is integrally molded by the heating element 20, the insulating layer 11, the bottom film 12 and the metal layer 13. Among them, the heating element 20 is completely embedded in the insulating layer 11, the bottom film 12 is located on the side of the heating element 20 away from the first plate plane 101, and the transmission member 30 is located on the second plate plane 102 away from the first plate plane 101. One end of the transmission member 30 passes through the insulating layer 11 and the bottom film 12, and is connected to the heating element 20, and the other end extends out of the cover body 10, and a connector 31 is fixed at the end, and the connector 31 can be connected to a power source, so that the heating element 20 is connected to the power source. The heating element 20 is fixed to the cover body 10 and shielded by the first plate plane 101.

[0058] Specifically, in one embodiment, the heating element 20 includes a heating wire, and the line of the heating wire is continuously bent to increase the distribution density of the heating wire. The projection of the heating element 20 on the first plate plane 101 is located within the first plate plane 101, that is, the projection of the heating element 20 on the first plate plane 101 is accommodated in the first plate plane 101, so that the first plate plane 101 can completely shield the heating element 20, and then the heat generated by the heating element 20 can be conducted from the first plate plane 101 to the passenger compartment.

[0059] When the heating element 20 is powered on, the heating element 20 generates heat and heats the cover 10. The temperature of the cover 10 increases, and the heat is transferred to the passenger compartment through the first plate plane 101 facing the passenger compartment, so as to increase the temperature inside the passenger compartment, thereby improving the comfort of the occupants in the passenger compartment. At the same time, controlling the power of the heating element 20 can control the heat generated by the heating element 20, thereby controlling the temperature inside the passenger compartment.

[0060] The heating device 100 of the present application is provided with a heating element 20 inside, and the heating element 20 is connected to the transmission member 30, and is connected to the power supply through the transmission member 30. The heating device 100 is fixedly connected to the vehicle body floor 90, and the cover 10 shields the hollow area 91 of the vehicle body floor 90, or the cover 10 is located in the hollow area 91 of the vehicle body floor 90, and the first plate plane 101 faces the passenger compartment. The heating element 20 generates heat after being energized, and the heat is conducted to the passenger compartment through the first plate plane 101, thereby increasing the temperature in the passenger compartment.

[0061] Generally, vehicles are equipped with air conditioning systems. When the temperature in the passenger compartment is low, the driver and passengers can turn on the air conditioning system to raise the temperature in the passenger compartment. The air conditioning system raises the temperature in the passenger compartment by blowing hot air into the passenger compartment. However, the hot air of the air conditioning system blows from the front end of the passenger compartment to the rear end of the passenger compartment, causing the front end of the passenger compartment to heat up faster and the rear end to heat up slower, which easily forms a temperature difference.

[0062] That is, there is a heating delay at the rear end of the passenger compartment. When the occupants at the front end are at a comfortable temperature, the temperature at the rear end has not yet risen to a comfortable temperature; when the occupants at the rear end are at a comfortable temperature, the temperature felt by the occupants at the front end is higher and may not be within a comfortable temperature range.

[0063] The heating device 100 of the present application is fixedly connected to the vehicle body floor 90, the first plate plane 101 faces the vehicle body floor 90, and the cover body 10 is located in the hollow area 91 of the vehicle body floor 90. The cover body 10 is arranged in the hollow area 91 of the vehicle body floor 90. When the heating device 100 is working, the heat generated is directly conducted to the inside of the passenger compartment to increase the temperature in the passenger compartment.

[0064] The heating device 100 of the present application is arranged below the passenger compartment. When the heating device 100 is working, the temperature of the front and rear ends can be increased at the same time, the heating delay of the rear end of the passenger compartment can be reduced, the front and rear ends of the passenger compartment can be evenly heated, and the comfort of the occupants in the passenger compartment can be improved. In addition, the heating device 100 of the present application has a second plate plane 102 that is away from the first plate plane 101. The second plate plane 102 can be attached to or embedded in other components that need to be heated. When the heating device 100 is working, the heat generated can also be conducted to other components that need to be heated, so that the heat generated by the heating device 100 is effectively utilized.

[0065] Specifically, in one embodiment, the second plate plane 102 is in contact with the battery 70 , and the heat generated by the heating device 100 can be conducted to the battery 70 through the second plate plane 102 , thereby increasing the temperature of the battery 70 and improving the performance of the battery 70 .

[0066] Compared with the air conditioning system of the passenger compartment, the heating device 100 of the present application is arranged on the vehicle body floor 90, which can evenly heat the space in the passenger compartment and has two plate planes for heating. When the heating device 100 is working, it can simultaneously increase the temperature of the passenger compartment and other components that need to be heated, thereby improving the utilization rate of the heat of the heating device 100 and reducing the energy consumption of the vehicle.

[0067] It should be pointed out that the heating device 100 of the present application can be applied to the above-mentioned vehicles as a component for uniformly heating the passenger compartment, and can also be used as a component for increasing the temperature of the passenger compartment and other components that need to be heated. It can replace the air conditioning system or auxiliary air conditioning system in the vehicle for heating, and reduce the energy consumption of the vehicle. However, the heating device is not limited to heating the interior of the vehicle passenger compartment. The heating device 100 of the present application is also applicable to other components or spaces that need to increase or maintain the temperature, and can heat evenly so that the occupants in the passenger compartment have a better experience. The heating device 100 of the present application has a high heat utilization rate, which is beneficial to energy saving and environmental protection.

[0069] In another embodiment, the cover 10 includes an inner cavity, and the heating element 20 is fixed in the inner cavity.

[0070] In another embodiment, the cover 10 includes a second plate plane 102 opposite to the first plate plane 101 , and the heating element 20 is fixed to the second plate plane 102 .

[0071] In the above specific embodiments, the heating element 20 can be fixedly connected to the cover body 10, and when the heating element 20 is working, the heat is transferred to the passenger compartment to achieve the heating of the space in the passenger compartment.

The insulating layer 11 includes a first insulating layer 11a away from the first plate plane 101, and a second insulating layer 11b facing the first plate plane 101. The heating element 20 is located between the first insulating layer 11a and the second insulating layer 11b, and the first insulating layer 11a and the second insulating layer 11b can completely cover the heating element 20, so that the heating element 20 is completely embedded in the insulating layer 11.

[0077] In some preferred embodiments, the material of the insulating layer 11 includes glass fiber cloth pre-impregnated with epoxy resin, composite materials sprayed with polyurethane, ceramic silicone cloth composite materials, high silicon oxide composite materials and other materials with good high temperature resistance and fire resistance. This can prevent the insulating layer 11 from being decomposed by heat when the temperature of the heating element 20 is too high, thereby reducing the insulation performance of the cover body 10.

[0078] In one embodiment, the materials and thicknesses of the first insulating layer 11a and the second insulating layer 11b may be different, and the materials and thicknesses thereof may be set based on the required thermal conductivity, high temperature resistance, fire resistance, and insulation performance.

The bottom film 12 can support the heating element 20 and improve the insulation effect of the cover 10. In addition, in this example, the bottom film 12 can be located on the side of the heating element 20 away from the first plate plane 101. In one embodiment of the present application, the bottom film 12 can also be integrally molded with the heating element 20 to improve integration efficiency.

[0080] In another embodiment, the cover body 10 includes an insulating layer 11, which forms an inner cavity, and the heating element 20 is fixed in the inner cavity. The bottom support film 12 is fixed to the side of the heating element 20 facing the second plate plane 102, and the bottom support film 12 at least partially covers the heating element 20.

The bottom film 12 can support the heating element 20 and improve the connection strength between the heating element 20 and the cover 10. At the same time, the heating element 20 can be prevented from directly contacting other components of the heating device 100, thereby protecting the heating element 20.

[0082] In another embodiment, the bottom supporting film 12 and the heating element 20 may also be hot-pressed into one piece, so that the bottom supporting film 12 and the heating element 20 are fixedly connected to support the heating element 20 .

[0083] In other embodiments, the bottom supporting film 12 may also be disposed on the side of the heating element 20 facing the vehicle body floor 90 to improve the insulation performance of the cover body 10 .

[0084] In some embodiments, the material of the bottom film 12 includes insulating materials such as PI, PET, mica and silica gel to improve the insulation performance of the cover 10.

[0085] In some embodiments, the size and shape of the bottom film 12 can be arbitrarily set based on the size and shape of the heating element 20 to support the heating element 20.

[0087] In one embodiment, the cover body 10 includes a metal layer 13, which covers the hollow area 91 of the vehicle body floor 90. The rigidity of the vehicle body floor 90 can meet the rigidity requirements of the vehicle. The cover body 10 can use a thinner metal layer 13 to reduce the weight of the cover body 10, thereby achieving lightweight heating device 100.

[0088] In another embodiment, the metal layer 13 shields the hollow area 91 of the vehicle body floor 90 , the rigidity of the vehicle body floor 90 meets the rigidity requirement of the vehicle, and the metal layer 13 includes metal foil. The thinner metal foil can reduce the weight of the cover 10 , thereby achieving lightweight heating device 100 .

[0089] In another embodiment, the cover 10 includes a metal layer 13, and the metal layer 13 is disposed in the hollow area 91 of the vehicle body floor 90. Due to the presence of the hollow area 91, the rigidity of the vehicle body floor 90 is reduced, which may cause the vehicle body floor 90 to fail to meet the rigidity requirements of the vehicle, thereby posing a safety hazard. To this end, the thickness of the metal layer 13 can be increased, and a thicker metal layer 13 can be used to increase the rigidity of the cover 10 and the vehicle body floor 90, thereby meeting the rigidity requirements of the vehicle.

The transmission member 30 is arranged on the second plate plane 102, one end of the transmission member 30 is connected to the heating element 20, and the other end is exposed from the cover body 10 to connect to a power source.

[0095] In one embodiment, see Figure 1 and Figure 2 The cover body 10 is integrally molded by the heating element 20, the insulating layer 11, the bottom film 12 and the metal layer 13. The heating element 20 is completely embedded in the insulating layer 11, the bottom film 12 is located on the side of the heating element 20 away from the first plate plane 101, and the transmission member 30 is located on the second plate plane 102 away from the first plate plane 101.

[0100] In one embodiment, the circuit of the heating element 20 includes multiple loops.

[0102] In some embodiments, the material of the heating wire includes metal, carbon-based polymer and ceramic. In other preferred embodiments, the material of the heating wire includes a material with a positive thermal sensitivity coefficient such as a carbon-based polymer or ceramic. The resistance of the heating wire with a positive thermal sensitivity coefficient increases with the increase of its temperature, so that the heating efficiency of the heating wire decreases.

[0103] It can be understood that the use of such a heating wire can make the heating element 20 have the characteristic of self-temperature control, that is, as the temperature of the heating element 20 increases, its heating efficiency decreases, so that the temperature of the heating element 20 can be maintained in a certain temperature range.

[0104] In other embodiments, the number, arrangement density, wire diameter, and material of the heating wires can be set based on the heating efficiency required by the heating device 100 .

[0118] In one embodiment, the projection of the heating element 20 can cover the battery 70 , which can improve the heating efficiency of the heating element 20 on the battery 70 and ensure the heating effect of the heating device 100 on the battery 70 .

[0119] In one embodiment, the projection of the heating wire can cover part of the side wall of the shell 40. Compared with the partition inside the shell 40, the side wall of the shell 40 is in contact with the external environment and has a higher heat dissipation performance, resulting in a temperature difference between the inside and the side wall of the shell 40. The temperature of the battery 70 near the side wall is lower, and the battery 70 may not be within a suitable temperature range. The projection of the heating wire covering part of the side wall of the shell 40 can increase the temperature of the side wall, reduce the temperature difference between the inside of the shell 40 and the side wall, so that the battery 70 near the side wall can also be kept within a suitable temperature range.

[0120] In another embodiment, the arrangement density of the heating wires can be set based on the heat dissipation performance of the shell 40 and the battery 70, so that the arrangement density of the heating wires at a higher heat dissipation performance is larger, and the arrangement density of the heating wires at a lower heat dissipation performance is smaller, thereby reducing the temperature difference inside the shell 40, improving the performance of the battery 70, and extending the life of the battery 70.
