Description

Technical Field

[0001] The utility model relates to the field of vehicle manufacturing, and particularly relates to a vehicle sunroof and a vehicle. Background Art

[0002] At present, more and more vehicles are equipped with panoramic sunroofs. Since heat enters the vehicle while light shines into the vehicle, in order to reduce the temperature inside the vehicle, most sunroofs are coated or equipped with sunshades.

[0003] In the prior art, the common coatings on the market reduce the light transmittance to achieve a certain heat insulation effect. However, in order to ensure the brightness of the view for the driver and passengers, the transmittance needs to be controlled not to be lower than a certain value during actual operation, resulting in poor heat insulation effect and poor actual experience for the driver and passengers. At the same time, since the vehicle air conditioner is generally arranged at the horizontal position of the console, due to the principle of cold air descending, after the air conditioner is turned on, the top of the vehicle body cools slowly, and the head feels less comfortable for passengers at the beginning of the ride. The panoramic sunroof can only passively insulate heat and lacks the effect of active cooling. In addition, if a sunshade is used to block light, it will affect the brightness of the view inside the vehicle. Summary of the Utility Model

[0034] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0035] Based on the lack of an active cooling function in the existing vehicle panoramic sunroof, a vehicle sunroof is proposed, specifically referring to Figure 1 , including insulating glass and a diversion channel;

[0036] The insulating glass includes an outer glass sheet and an inner glass sheet stacked, and a cavity is provided between the outer glass sheet and the inner glass sheet; the cavity is communicated with the external space of the insulating glass or the cooling system of the vehicle through the diversion channel.

[0037] As can be seen from the above description, the beneficial effects of the present utility model are as follows: A vehicle sunroof is provided, which uses insulating glass including double-layer glass inside and outside as the main body of the panoramic sunroof. At the same time, a cavity is provided between the outer glass plate and the inner glass plate, and the inside of the cavity is communicated with the outside through a diversion channel. The air inside the cavity is circulated with the outside through the diversion channel, so as to conduct heat exchange, actively reduce the heat brought by light, and form a dynamic heat insulation layer by using the gas flow in the cavity, ensuring the brightness of the field of vision while reducing the heat transferred to the interior of the vehicle.

[0038] It should be noted that the forming method of the outer glass plate and the inner glass plate in the insulating glass can be to glue and seal the outer glass plate and the inner glass plate, but a space for embedding the diversion channel into the cavity is reserved in the insulating glass, and the inner double-layer sealant method is used for gluing and sealing when setting the diversion channel. At the same time, in order to prevent the air flow from being chaotic, a direction valve is set in the diversion channel to control the air flow direction; in the embodiment of the present utility model, the diversion channel can be manually closed, that is, when the driver feels comfortable, the diversion channel can be selected to be closed.

[0039] Preferably, please refer to Figure 4 , a plurality of small pipes are provided at the connection between the diversion channel and the cavity to communicate with the cavity, and are respectively arranged at the edge of the cavity at a preset interval, so as to evenly dissipate heat and cool down the cavity.

[0040] Specifically, the diameter range of the diversion channel is between 20 - 100 mm, preferably one of 20 mm, 40 mm, 60 mm, 80 mm and 100 mm; the pipe material can be selected from: PU, PVC, PP + glass fiber, ABS, PP, PPMA, rubber, etc.; the cooling system can be the air conditioning system of the vehicle itself, or an independent cooling system can be set according to requirements.

[0041] In some embodiments, the insulating glass further includes a spacer frame, and the spacer frame is arranged between the outer glass plate and the inner glass plate and is hermetically connected to the outer glass plate and the inner glass plate respectively. By arranging the spacer frame between the inner and outer glass plates, a cavity is generated between the inner and outer glasses by using the thickness of the spacer frame, simplifying the manufacturing process and saving production costs.

[0042] In some embodiments, a photovoltaic assembly is further included, and the photovoltaic assembly includes a solar chip. The solar chip is close to the spacer frame and is arranged in the cavity. Since the sunroof is arranged on the vehicle roof and has good lighting conditions, the solar chip is arranged in the cavity, and the solar chip is arranged along the spacer frame to avoid affecting the lighting inside the vehicle, and the recovered energy is incorporated into the vehicle power system.

[0043] In some embodiments, the diversion channel includes at least one inflow channel that communicates with the outflow end of the cooling system. That is, the cooling medium of the cooling system is discharged into the cavity through the inflow channel, thereby taking away the heat in the cavity and achieving active cooling.

[0044] Preferably, in order to prevent external impurities from entering the cavity, a filtering device is provided inside the inflow channel to remove debris in the medium flowing into the cavity.

[0045] In some embodiments, the diversion channel further includes at least one outflow channel that communicates with the return end of the cooling system. The cavity communicates with the outflow end and the return end of the cooling system through the diversion channel respectively. That is, the gas in the cavity enters the cycle of the cooling system through the diversion channel, and the active cooling effect is achieved by using the cooling system, making the cooling effect controllable.

[0046] In some embodiments, the cooling system is a liquid cooling system. The outflow end of the liquid cooling system communicates with the inflow channel located at the highest position in the cavity, and the return end of the liquid cooling system communicates with the outflow channel located at the lowest position in the cavity. A liquid cooling system is provided in the skylight to achieve active cooling. In order to avoid residual coolant and facilitate evacuation of the liquid, the outflow end of the coolant is set at the highest position in the cavity, and the return end of the coolant is set at the lowest position in the cavity, so that the coolant fills from top to bottom and is evacuated from the lowest point of the diversion channel in the cavity when returning, facilitating recovery of the coolant, avoiding residual coolant from affecting the line of sight, and further improving the cooling effect compared with air cooling.

[0047] It should be noted that the lowest position and the highest position proposed in this example refer to the relative positions after the vehicle skylight is installed on the vehicle.

[0048] In some embodiments, the diversion channel further includes at least one outflow channel that communicates with the external space of the vehicle. The hot air discharged from the cavity no longer participates in the internal cycle of the cooling system and is directly discharged to the outside of the vehicle through the diversion channel, thereby achieving active cooling while saving air conditioning energy consumption.

[0049] In some embodiments, at least one fan assembly is further included. The fan assembly includes a bracket and a fan; the fan is disposed inside the diversion channel, and the bracket is used to install the fan in the diversion channel. By the operation of the fan in the diversion channel, the air flow is accelerated. Specifically, the blowing direction of the fan is set according to the connection end or the opening orientation of the diversion channel.

[0050] In some embodiments, the bracket includes at least two support blocks, and all the support blocks are arranged at equal intervals along the circumferential direction of the diversion channel. The support blocks arranged circumferentially fix the fan in the middle of the diversion channel, so that it is more conducive to maintaining the balance of the fan itself when the fan is subjected to air disturbance; preferably, the fan is a DC axial-flow fan, and a brushless motor is arranged at the tail to drive the fan blades to operate.

[0051] A vehicle includes a vehicle sunroof. The diversion channel includes at least one inflow channel and at least one outflow channel. The openings of the inflow channel and the outflow channel are respectively located at both side parts in the length direction of the vehicle. The openings of at least one diversion channel face the head of the vehicle, and the acceleration generated when the vehicle is running is used to promote the air circulation in the cavity between the inner and outer glass plates. At the same time, the openings of at least one diversion channel face the tail of the vehicle, reducing the flow resistance of the gas in the cavity, facilitating the rapid discharge of the gas in the air when the vehicle is running, so as to achieve active cooling without adding other auxiliary devices.

[0052] The present invention provides a vehicle sunroof and a vehicle, which are mainly used to achieve the active cooling effect of the panoramic sunroof of the vehicle. The specific description is as follows in combination with the embodiments:

[0053] Please refer to Figure 1 , Figure 2 and Figure 6 In the first embodiment of the present invention: A vehicle includes a vehicle sunroof composed of a hollow glass 1 and a diversion channel 2; the hollow glass 1 includes an outer glass plate 12 and an inner glass plate 11 arranged in a stacked manner, and a cavity 13 is provided between the outer glass plate 12 and the inner glass plate 11; the cavity 13 is communicated with the outside through the diversion channel 2. The number of the diversion channels 2 is 6; all the diversion channels 2 are communicated with the outside of the vehicle, and 3 diversion channels 2 are used as inflow channels 22, and their openings face the head of the vehicle, and 3 diversion channels 2 are used as outflow channels 23, and their openings face the tail of the vehicle. The openings of 3 diversion channels 2 face the head of the vehicle, and the acceleration generated when the vehicle is running is used to promote the air circulation in the cavity 13 between the inner and outer glass plates 12. At the same time, the openings of 3 diversion channels 2 face the tail of the vehicle, reducing the flow resistance of the gas in the cavity 13, facilitating the rapid discharge of the gas in the air when the vehicle is running, so as to achieve active cooling without adding other auxiliary devices. At the same time, an air filter 21 is arranged in the diversion channel 2 where the air flows in to prevent external dust and water vapor from entering the cavity 13, resulting in the sunroof becoming dirty or water vapor liquefying and frosting, etc., which affects the vision.

[0054] At the same time, in order to prevent external impurities from entering the cavity 13, a filtering device is arranged inside the inflow channel 22 to remove the debris in the medium flowing into the cavity 13.

[0055] Please refer to Figure 1 ,Figure 3 and Figure 7 For the second embodiment of the present utility model: The difference between this embodiment and the first embodiment lies in the different connection ends of the diversion channels 2. Specifically, the number of the diversion channels 2 is 10. Four of the diversion channels 2 serve as the inflow channels 22 and are connected to the outflow end of the vehicle's own cooling system 4, and six of the diversion channels 2 serve as the outflow channels 23 and are connected to the return end of the vehicle air-conditioning system. The gas in the cavity 13 is added to the internal circulation of the vehicle air-conditioning system through the diversion channels 2, and the active cooling effect is achieved by grafting the air-conditioning pipelines, making the cooling effect controllable.

[0056] Specifically, two small pipelines are arranged at the connection between the diversion channel 2 and the cavity 13 to communicate with the cavity 13, and are respectively arranged at the edge of the cavity 13 at a preset interval, so as to evenly dissipate heat and cool down the cavity 13.

The hot air discharged from the cavity 13 no longer participates in the internal circulation of the cooling system 4 and is directly discharged to the outside of the vehicle through the diversion channels 2, thereby achieving active cooling while saving air-conditioning energy consumption.

[0058] Please refer to Figures 9 to 10 For the fourth embodiment of the present utility model: On the basis of any one of the vehicles in the first to third embodiments, at least one fan assembly 3 is further included. The fan assembly 3 includes a bracket 31 and a fan 32; the fan 32 is arranged inside the diversion channel 2, and the bracket 31 is used to install the fan 32 in the diversion channel 2.

[0059] Specifically, the bracket 31 includes support blocks. The number of the support blocks is 6, and the support blocks are arranged at equal intervals along the circumferential direction of the diversion channel 2. The circumferentially arranged support blocks fix the fan 32 in the middle of the diversion channel 2, so that the fan 32 is more conducive to maintaining its own balance when bearing air disturbance; preferably, the fan 32 adopts a DC axial-flow fan 32, and a brushless motor is arranged at the tail to drive the fan blades to operate.

[0060] Embodiment 5 of the present utility model is as follows: On the basis of any one of the vehicles in Embodiments 1 to 3, the insulating glass 1 further includes a spacer frame. The spacer frame is disposed between the outer glass plate 12 and the inner glass plate 11 and is hermetically connected to the outer glass plate 12 and the inner glass plate 11 respectively. By arranging the spacer frame between the inner and outer glass plates 12, a cavity 13 is formed between the inner and outer glasses by using the thickness of the spacer frame, simplifying the manufacturing process and saving production costs. Preferably, the spacer frame and the inner and outer glass plates 12 are adhesively sealed. In order to improve the sealing effect, a secondary gluing method is adopted to form an inner and outer double glue layer.

[0061] It further includes a photovoltaic assembly. The photovoltaic assembly includes a solar chip. The solar chip is close to the spacer frame and is disposed in the cavity 13. Since the sunroof is arranged on the roof of the vehicle and has good lighting conditions, the solar chip is arranged in the cavity 13 and the solar chip is arranged along the spacer frame, avoiding affecting the lighting inside the vehicle. The recovered energy is incorporated into the vehicle power system or used for the operation of the above-mentioned fan 32.
