Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a roof assembly of a vehicle and the vehicle. Background Art

[0002] When a vehicle is used for a long time in a low-temperature environment, the roof sheet metal of the vehicle is a good conductor of heat, which also makes the temperature of the vehicle's roof low. The water vapor in the passenger compartment will condense and freeze on the inner surface of the roof, forming ice accumulation on the inside of the roof. After multiple driving cycles, the ice accumulation thickens. After the vehicle is washed or put into a heating room, the ambient temperature rises rapidly, the ice on the roof melts, and the melted water drops flow on the inner surface of the roof and gather in low-lying areas. When the water accumulates to a certain extent, it will slowly seep into the opening of the ceiling light and the cut edges of the pillars, and may also drip down onto the seats and other parts in the car.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Reference below Figure 1-Figure 3 A roof cover assembly 100 of a vehicle according to an embodiment of the present invention is described.

[0029] The vehicle roof assembly 100 according to the first embodiment of the utility model comprises: a roof body 10, an interior layer 20 and a heating structure 30. The roof body 10 is a metal part, for example, the roof body 10 can be a sheet metal part, the interior layer 20 is arranged on the inner side of the roof body 10, the heating structure 30 is arranged between the roof body 10 and the interior layer 20, and the heating structure 30 is fixed to the roof body 10 to heat the roof body 10.

[0030] For example, the heating structure 30 is disposed between the top cover body 10 and the interior layer 20 and fixed to the inner side of the top cover body 10. The heating structure 30 can transfer heat to the top cover body 10 by being powered on for heating. When the outside temperature is low, the heating structure 30 is powered on to increase its own temperature and transfer heat to the top cover body 10, thereby increasing the temperature of the top cover body 10 and preventing water vapor from cooling, liquefying, solidifying and forming ice on the top cover body 10. When the outside temperature rises, the heating structure 30 is disconnected from the power supply to save energy.

[0031] Optionally, after the heating structure 30 heats the top cover body 10, the temperature of the top cover body 10 is higher than the temperature of the water vapor in the cockpit, so that the water vapor in the cockpit cannot dissipate heat and cool at the top cover body 10, so that ice will not accumulate on the top cover body 10. At the same time, the heating structure 30 can also serve as an auxiliary heat source to increase the temperature in the cockpit, making the user more comfortable in a cold environment.

[0032] Optionally, after the heating structure 30 heats the top cover body 10, the temperature of the top cover body 10 is lower than the temperature of the water vapor in the cockpit, but the temperature difference between the top cover body 10 and the water vapor in the cockpit is not enough to allow the water vapor to dissipate enough heat to condense into liquid, so that no water or ice will accumulate on the top cover body 10.

[0033] When the outside temperature is low, the heating structure 30 transfers heat to the top cover body 10, for example, by heating the heating structure 30 with electricity to increase its temperature, or by energizing the heating structure 30 to generate heat radiation, so that the heating structure 30 transfers heat to the top cover body 10, thereby increasing the temperature of the top cover body 10. The water vapor in the cockpit will not be cooled, liquefied, or solidified on the top cover body 10, so that ice will not accumulate on the inside of the top cover body 10. When the outside temperature rises, since there was no ice accumulation on the inside of the top cover body 10 before, the ice layer will not melt, causing water stains or water droplets to fall on the interior layer 20, thereby improving the user experience.

[0034] Optionally, the roof assembly 100 includes a sun visor 21 and a roof light.

[0035] Optionally, the roof assembly 100 further includes a roof front crossbeam 11, which is located at the front of the roof body 10. The roof front crossbeam 11 can be used to strengthen the support of the roof body 10, and provide installation positions for other components such as the sun visor 21 and the ceiling light. In addition, the roof front crossbeam 11 can be used as a stop point for the heating structure 30, which is used to position the heating structure 30 during installation, so as to facilitate the installation of the heating structure 30.

[0036] Optionally, the material of the top cover front cross beam 11 is the same as that of the top cover body 10 , for example, the top cover front cross beam 11 and the top cover body 10 are both sheet metal parts.

[0037] According to the vehicle roof assembly 100 of the embodiment of the utility model, by setting a heating structure 30 between the roof body 10 and the interior layer 20 and fixing the heating structure 30 on the roof body 10, the roof body 10 can be heated by the heating structure 30, so that the temperature of the roof body 10 can be increased, and the water vapor in the passenger compartment can be prevented from condensing and freezing into ice on the roof assembly 100, thereby avoiding the problem of water stains or water drops on the interior layer 20 caused by the melting of ice accumulated on the inside of the roof assembly 100 when the ambient temperature around the vehicle rises rapidly. In addition, by fixing the heating structure 30 on the roof body 10, since the roof body 10 is a metal part with high structural strength, it can provide stable and reliable support and fixation for the heating structure 30, and can reduce the heat loss in the process of the heating structure 30 transferring heat to the roof body 10, thereby improving the heating effect on the roof body 10.

[0038] According to some embodiments of the present invention, referring to Figure 1-Figure 3 The heating structure 30 is bonded and fixed to the top cover body 10. By bonding and fixing the heating structure 30 to the top cover body 10, the heating structure 30 can be easily installed.

[0039] According to some embodiments of the present invention, referring to Figure 1 , the heating structure 30 is spaced apart from the interior layer 20. Optionally, the interior layer 20 may be a plastic part for easy molding. By spaced apart from the interior layer 20, the heating structure 30 and the interior layer 20 can be prevented from directly contacting each other, and the heating structure 30 can be prevented from transferring a large amount of heat to the interior layer 20, causing the temperature of the interior layer 20 to rise and accelerate the aging of the interior layer 20, thereby ensuring the service life of the interior layer 20.

[0040] According to some embodiments of the present invention, referring to Figure 2The heating structure 30 includes: a heating layer 31, a first insulating protective layer 32, a second insulating protective layer 33 and a sound insulation layer 34. The first insulating protective layer 32 and the second insulating protective layer 33 are respectively located on opposite sides of the heating layer 31 in the thickness direction. The first insulating protective layer 32 is located on one side of the heating layer 31 close to the top cover body 10.

[0041] For example, the temperature of the heating layer 31 is increased by energizing. At this time, the heating layer 31 is a conductive member, and the first insulating protective layer 32 and the second insulating protective layer 33 are respectively located on opposite sides of the thickness direction of the heating layer 31. By arranging the first insulating protective layer 32 and the second insulating protective layer 33 on opposite sides of the conductive heating layer 31 in the thickness direction, the heating layer 31 can be prevented from contacting with other conductive members or water vapor to prevent a short circuit from causing danger.

[0042] For example, the heating structure 30 includes a first adhesive layer 36, which is disposed on a side of the first insulating protective layer 32 close to the top cover body 10, and the first adhesive layer 36 is connected to the top cover body 10. For example, the first adhesive layer 36 can be made of epoxy resin glue. The first adhesive layer 36 can be used to adhere the heating structure 30 and the top cover body 10, so as to facilitate fixing the heating structure 30 on the cover body.

[0043] For example, the heating structure 30 is connected to the isolation paper 39, and the isolation paper 39 is arranged on the outside of the first adhesive layer 36 to protect the first adhesive layer 36 before the heating structure 30 is installed. Optionally, the isolation paper 39 can be a coated kraft paper. By arranging the isolation paper 39 on the outside of the first adhesive layer 36, the first adhesive layer 36 can be protected before the heating structure 30 is fixed to the top cover body 10, to prevent dust or other components from contacting the first adhesive layer during transportation and affecting the effect of the first adhesive layer. When the heating structure 30 is fixed to the top cover body 10, the isolation paper 39 is first removed to expose the first adhesive layer, and then the first adhesive layer 36 is connected to the top cover body 10 so that the heating structure 30 can be fixed to the top cover body 10.

[0044] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The sound insulation layer 34 is located on the side of the second insulating protective layer 33 away from the top cover body 10. By providing the sound insulation layer 34, the heating structure 30 can have the function of increasing the temperature of the top cover body 10 while also having the function of sound insulation and noise reduction. By providing the sound insulation layer 34 on the side of the second insulating protective layer 33 away from the top cover body 10, the position of the sound insulation layer 34 will not affect the heat transfer from the heating layer 31 to the top cover body 10, so that the heating structure 30 can work more quickly.

[0045] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The sound insulation layer 34 is a foam layer. For example, the sound insulation layer 34 can be a polyurethane foam sheet. The foam layer has good NVH performance and can play a good role in sound insulation and noise reduction.

[0046] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The sound insulation layer 34 is bonded to the second insulating protective layer 33. For example, the heating structure 30 includes a second adhesive layer, and the second adhesive layer is disposed between the sound insulation layer 34 and the second insulating layer. The second adhesive layer can bond and connect the sound insulation layer 34 and the second insulating protective layer 33.

[0047] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the heating device includes a plastic sealing layer 35. By providing the plastic sealing layer 35 in the heating device, water vapor can be prevented from entering the heating layer 31 and causing danger. The plastic sealing layer 35 is arranged on the side of the sound insulation layer 34 close to the interior layer 20. For example, the heating structure 30 includes a third adhesive layer 38, and the third adhesive layer 38 is arranged between the plastic sealing layer 35 and the sound insulation layer 34. By providing the third adhesive layer 38, the plastic sealing layer 35 and the sound insulation layer 34 can be adhered and fixed.

[0048] Optionally, the plastic sealing layer 35 is a laminated kraft paper, which is waterproof and can isolate water vapor.

[0049] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The heating layer 31 is a graphene heating layer 31. The graphene heating layer 31 saves energy, consumes less electricity, and is more environmentally friendly. In addition, graphene has good thermal conductivity and generates heat quickly, so the use of the graphene heating layer 31 is more efficient.

[0050] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The first insulating protective layer 32 and the second insulating protective layer 33 are both insulating waterproof films. By providing insulating waterproof films on both sides of the heating layer 31 in the thickness direction, the graphene can be insulated and protected.

[0051] According to some embodiments of the utility model, it includes: a temperature sensor, which is arranged on the top cover body 10, and is used to detect the temperature of the top cover body 10. The detection result of the temperature sensor is used as a basis for controlling the heating structure 30. By setting the temperature sensor, the heating structure 30 can be automatically turned on when the external environment temperature is low, and automatically turned off when the external environment temperature rises, saving the consumption of electric energy. At the same time, automatic temperature adjustment is realized, avoiding the need for manual monitoring of temperature to turn it on or off, and improving the user experience.

[0052] The vehicle according to the embodiment of the second aspect of the utility model comprises: the top cover assembly 100 according to the embodiment of the first aspect of the utility model.

[0053] Optionally, the vehicle includes a battery. The battery serves as a power source of the vehicle to supply power to the vehicle. When the heating layer 31 works by being energized, the battery can also supply power to the heating layer 31 .

[0054] Optionally, the vehicle includes a switch that can be used to disconnect or connect the power source to the heating structure 30 , and the user can manually control the activation of the heating structure 30 through the switch.

[0055] Optionally, the vehicle includes a controller, which is respectively connected to the power supply, the temperature sensor, and the heating structure 30. When the ambient temperature is low, the temperature sensor sends a signal to the controller, and the controller controls the battery to supply power to the heating structure 30 to increase the temperature of the top cover body 10.

[0056] According to the vehicle of the embodiment of the utility model, by setting the roof assembly 100 of the vehicle of the first aspect of the utility model, ice will not accumulate on the roof cover body 10 when the ambient temperature is low, thereby preventing the melting of ice from causing water stains or water dripping on the interior layer 20, thereby improving the user experience.
