Description

Technical Field

[0001] The invention relates to an automobile structure, and in particular to a skylight glass structure with zoned cooling, a roof and a vehicle. Background Art

[0002] With the continuous advancement of technology and the widespread popularity of family cars, users' aesthetic standards for car appearance and expectations for the brightness of the interior space are increasing. Under this trend, the number of models equipped with skylight glass has increased significantly. However, in actual use, such models have exposed many problems that need to be solved.

[0003] In the summer when the temperature is high and the sun is shining directly, the thermal insulation performance of the skylight glass is very weak. Since it cannot effectively block the heat from entering the car, the temperature inside the car rises sharply. This will not only make the passengers feel extremely hot and seriously affect the comfort of using the car in summer, but also may damage the interior decoration materials, electronic equipment, etc. due to the high temperature, shortening their service life and increasing the maintenance cost of the vehicle. A large number of users have given strong feedback on this issue and expressed dissatisfaction.

[0004] The mainstream solution adopted by the current market to address this problem is to install sunshades at the bottom of the skylight glass. It is undeniable that this method can alleviate the heat transfer to a certain extent and reduce the rate of temperature rise in the car. However, this method has obvious disadvantages. The installation of sunshades makes the originally open and bright interior space dim, the panoramic view is largely blocked, and the light transmittance in the car is greatly reduced. Passengers cannot fully enjoy the transparent visual experience in the car, which is undoubtedly a great sacrifice for users who pursue high-quality driving experience. Moreover, the sunshade only forms a barrier on the roof of the car, and the heat blocking effect is relatively limited. It is difficult to fundamentally solve the heat insulation problem of the skylight glass, and it cannot meet the user's dual requirements for comfort and visual effects in the car.

[0005] In order to better solve the heat insulation problem of the roof skylight glass currently on the market without affecting the user's visual experience, the present invention proposes a zoned cooling skylight glass structure, a roof and a vehicle. Summary of the invention

[0006] The purpose of the present invention is to provide a sunroof glass structure, a roof and a vehicle with zoned cooling, which can transmit low-temperature air to the heat dissipation cavity at the bottom of the sunroof glass through the air duct system to achieve a cooling effect on the sunroof glass exposed to the sun. At the same time, the low-temperature air in the heat dissipation cavity is discharged from the heat dissipation holes at the bottom of the heat dissipation cavity under the pressure of the air duct system, realizing a continuous input circulation of cold air to overcome the shortcomings of the passenger comfort problem caused by the poor heat insulation effect of the sunroof glass in the prior art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: In the first aspect, the present invention provides a canopy glass structure for zoned cooling, including a canopy glass, a plurality of heat dissipation cavities are arranged on the inner surface of the canopy glass, the heat dissipation cavities and the inner surface of the canopy glass form a semi-enclosed cavity structure, a plurality of air outlets are evenly arranged on the heat dissipation cavity, a duct system is arranged on both sides of the canopy glass, the heat dissipation cavities are independent of each other and connected to the duct system, and an opening and closing device is slidably arranged at the connection between the heat dissipation cavity and the duct system. By continuously inputting duct cold air into the plurality of heat dissipation cavities on the inner surface of the canopy glass, the cold air is continuously circulated in the canopy glass itself and the semi-enclosed cavity structure formed by the heat dissipation cavity and the inner surface of the canopy glass, so that the cold air enters the heat dissipation cavity through the duct system and is discharged from the plurality of air outlets arranged on the heat dissipation cavity, thereby reducing the air temperature near the head of the passenger below and improving the comfort of the passenger. By controlling the connection relationship between the duct system and each heat dissipation cavity at the bottom of the canopy, and the opening and closing device is slidably arranged at the connection between the heat dissipation cavity and the duct system, independent cooling of the area requiring cooling is achieved. The remaining areas that do not require cooling will not be ventilated or cooled, thereby achieving the function of reducing energy consumption.

[0008] Further, the air duct system includes an air duct, one end of which is connected to a fan, a plurality of air duct outlets are arranged on the pipe body of the air duct, the air duct outlets are connected to the heat dissipation cavity, and the opening and closing device is arranged at the connection between the air duct outlet and the heat dissipation cavity. The opening and closing device can open or close the connection between the air duct outlet and the heat dissipation cavity.

[0009] Furthermore, the opening and closing device includes a first slider, which is slidably arranged at the connection between the air duct outlet and the heat dissipation cavity. When the first slider moves up, the air duct outlet is blocked, and the cold air in the duct cannot enter the transparent heat dissipation cavity, thereby turning off the cooling function; when the first slider slides down, the air duct outlet and the heat dissipation cavity are connected, and the cold air in the duct can enter the transparent heat dissipation cavity, thereby realizing the cooling function.

[0010] Furthermore, the opening and closing device includes a driving motor and a second slider, the driving motor includes a motor body, a motor reduction box is provided on the motor body, a screw mechanism is provided on the motor reduction box, a slider nut is provided on the second slider, and the slider nut is connected to the screw mechanism. The driving motor rotates clockwise to drive the screw mechanism to move linearly, so that the slider nut moves and then drives the second slider to move upward to block the air outlet of the air duct, and the driving motor rotates counterclockwise to drive the screw mechanism to move linearly, so that the slider nut moves and then drives the second slider to slide downward, so that the air outlet of the air duct and the heat dissipation cavity are connected.

[0011] Furthermore, the driving motor is arranged on the air duct.

[0012] Furthermore, the driving motor is arranged on the skylight glass. Furthermore, the heat dissipation cavity is arranged in the main driver's seat, the co-driver's seat, the left side of the rear seat, and the right side of the rear seat, which can more effectively and evenly cool the air near the heads of passengers in each area, further improving the comfort experience of all passengers when using and riding in the car in summer.

[0013] Furthermore, the heat dissipation cavity is made of transparent material and does not affect the visual effect of the roof skylight glass.

[0014] In a second aspect, the present invention provides a vehicle roof, including a vehicle roof body, wherein the vehicle roof body includes the above-mentioned zoned cooling skylight glass structure.

[0015] In a third aspect, the present invention provides a vehicle, comprising the above-mentioned roof.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a skylight glass structure with zoned cooling. By continuously inputting duct cold air into multiple heat dissipation cavities on the inner surface of the skylight glass, the cold air is continuously circulated in the skylight glass and the semi-enclosed cavity structure formed by the skylight glass and the heat dissipation cavity, and discharged from multiple air outlets on the heat dissipation cavity, the air temperature near the head of the passenger below can be effectively reduced, thereby improving the passenger's riding comfort. With the help of an opening and closing device set at the connection between the air duct system and the heat dissipation cavity, and each heat dissipation cavity is independent of each other and can be independently connected or closed, the opening and closing device can control the connection relationship between the air duct system and each heat dissipation cavity at the bottom of the skylight, thereby realizing independent cooling of the area that needs to be cooled. When there are no passengers in certain positions, the air outlet channel of the area can be closed, thereby reducing the cold air loss and maximizing the cold air cooling effect.

[0017] The present invention is designed with a skylight glass heat dissipation cavity in four areas, namely the main driver's seat, the co-driver's seat, the left side of the rear row, and the right side of the rear row. The cold air is delivered through multiple air outlets in the heat dissipation cavity, and the cold air output is uniform and stable. The air near the heads of passengers in each area can be cooled more effectively and evenly. The comfort experience of all passengers when using and riding in the car in summer is further improved. Ventilation and cooling can be performed on the areas that need to be cooled, while ventilation operations are not performed on the other areas that do not need to be cooled, thereby avoiding energy waste and effectively reducing energy consumption during use.

[0018] The heat dissipation cavity of the present invention is made of transparent material and will not block the light from the skylight glass roof, thereby not affecting the user's demand for the light transmittance of the roof and the panoramic visual effect when riding in the vehicle.

[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] In order to better solve the heat insulation problem of roof skylight glass on the current market without affecting the user's visual experience, the present invention provides a zoned cooling skylight glass structure, which can more effectively solve the problem of user complaints caused by poor heat insulation of the skylight glass in summer without affecting the user's light transmittance and panoramic visual experience of the roof, and can more effectively cool the skylight glass and the air near the passenger's head.

[0027] See also Figure 1 A skylight glass structure for zoned cooling includes a skylight glass 1, a plurality of heat dissipation cavities 2 are arranged on the inner surface of the skylight glass 1, the heat dissipation cavity 2 and the inner surface of the skylight glass 1 form a semi-enclosed cavity structure, the heat dissipation cavity 2 is evenly provided with a plurality of air outlets 3, a duct system 10 is arranged on one side of the skylight glass 1, the heat dissipation cavities 2 are independent of each other and connected to the duct system 10, and an opening and closing device is slidably arranged at the connection between the heat dissipation cavity 2 and the duct system 10. The inner surface of the skylight glass 1 refers to the side facing the interior of the vehicle; when the opening and closing device is in an open state, cold air will be transported to the independent heat dissipation cavity 2 through the duct system 10, and will continuously circulate in the semi-enclosed cavity structure formed by the skylight glass 1 and the heat dissipation cavity 2, and then discharged from the plurality of air outlets 3 evenly arranged on the heat dissipation cavity 2, so as to achieve cooling of the corresponding area; when the opening and closing device is in a closed state, the area corresponding to the heat dissipation cavity 2 stops cooling, so as to achieve the effect of zoned controlled cooling.

[0028] In some preferred embodiments of the present invention, the air duct system 10 includes an air duct 4, one end of which is connected to a fan, a plurality of air duct outlets 5 are provided on the pipe body of the air duct 4, the air duct outlets 5 are connected to the heat dissipation cavity 2, and the opening and closing device is provided at the connection between the air duct outlets 5 and the heat dissipation cavity 2. The cold air generated by the air conditioning system passes through the air duct outlets 5 and continuously enters the heat dissipation cavity 2 at the bottom of the skylight glass 1, and cools the skylight glass 1 and the air at the bottom of the skylight glass.

[0029] In some preferred embodiments of the present invention, the heat dissipation cavity 2 is made of transparent material, which changes the traditional method of using sunshade cloth to block light and insulate, and will not block the light from the roof of the skylight glass 1, thereby not affecting the user's demand for the roof's light transmittance and panoramic visual effect when riding.

[0030] In some preferred embodiments of the present invention, the heat dissipation cavity 2 is arranged above the heads of passengers in the four areas of the main driver's seat, the co-driver's seat, the left side of the rear row, and the right side of the rear row. When there is no passenger on the left side of the rear row, the opening and closing device between the independent heat dissipation cavity 2 in the rear left area and the air duct outlet 5 can be closed; when there is no passenger on the right side of the rear row, the opening and closing device between the independent heat dissipation cavity 2 in the rear right area and the air duct outlet 5 can be closed; when there is no passenger on the co-driver's seat, the opening and closing device between the independent heat dissipation cavity 2 in the co-driver's seat and the air duct outlet 5 can be closed, so as to realize independent cooling of the areas that need cooling. The other areas that do not need cooling are not ventilated and cooled, so as to realize the function of reducing energy consumption.

[0031] In some preferred embodiments of the present invention, the heat dissipation cavity 2 is evenly provided with a plurality of air outlet holes 3 which can be distributed in a matrix form. After entering the heat dissipation cavity 2, the cold air is evenly blown to passengers at various positions through the matrix holes. The cold air is blown accurately and evenly, greatly improving the comfort of the passengers.

[0032] Example 2 See also Figure 1 , Figure 3 and Figure 4 Based on Example 1, the opening and closing device is further described. The opening and closing device includes a first slider 7, which is slidably arranged at the connection between the air duct outlet 5 and the heat dissipation cavity 2. When the first slider 7 moves up, the air duct outlet 5 is blocked. When the first slider 7 slides down, the air duct outlet 5 and the heat dissipation cavity 2 are connected.

[0033] In some preferred embodiments of the present invention, initially, the passages between the air duct outlets 5 and the heat dissipation cavity 2 in the driver's seat, the co-driver's seat, the rear left side, and the rear right side are all closed. Figure 4 It is a schematic diagram of the opening state of the opening and closing device. When the driver's seat, the co-driver's seat, the left side of the rear row, and the right side of the rear row need to be cooled, the first slider 7 of each area slides down, and the channel between the air duct outlet 5 and the heat dissipation cavity 2 is opened. At this time, the cold air generated by the air-conditioning system can pass through the air duct 4 and the air duct outlet 5, smoothly enter the heat dissipation cavity 2, and then be discharged from the air outlet holes 3 evenly distributed on the heat dissipation cavity 2, thereby achieving cooling of the driver's seat, the co-driver's seat, the left side of the rear row, and the right side of the rear row.

[0034] like Figure 3 This is a schematic diagram of the closed state of the opening and closing device. When the passenger area does not need to be cooled, the first slider 7 of the passenger area is moved upward, and the passage between the air duct outlet 5 and the heat dissipation cavity 2 is closed. In this case, the cold air in the air duct 4 of the passenger area cannot enter the heat dissipation cavity 2 through the air duct outlet 5, and the cold air can only enter other independent heat dissipation cavities 2 through the air duct outlet 5 of other unclosed areas, so that the cooling of the passenger area stops. When all areas do not need to be cooled, all the first sliders 7 are moved upward, the passage between the air duct outlet 5 and the heat dissipation cavity 2 is closed, and the cold air continues to flow in the air duct 4.

[0035] In some preferred embodiments of the present invention, the first slider 7 is slidably arranged at the connection between the air duct outlet 5 and the heat dissipation cavity 2. Specifically, a track is arranged at the edge of the connection between the air duct outlet 5 and the heat dissipation cavity 2, and the first slider 7 can slide by being embedded in the track; for example, the track can be in the shape of a dovetail groove or a T-shaped groove. The dovetail groove-shaped track can well limit the sliding of the first slider 7 in the vertical direction and prevent it from being displaced in other directions. The first slider 7 is correspondingly provided with a protrusion matching the track. Through the cooperation of this protrusion and the track, the first slider 7 can stably slide up and down at the connection between the air duct outlet 5 and the heat dissipation cavity 2, thereby accurately controlling the opening and closing of the air duct outlet 5.

[0036] Example 3 See also Figure 1 to Figure 2 On the basis of Example 1, the opening and closing device is further described. The opening and closing device includes a driving motor 6 and a second slider 12. The driving motor 6 includes a motor body 13. The motor body 13 is provided with a motor reduction box 8. The motor reduction box 8 is provided with a screw mechanism 9. The second slider 12 is provided with a slider nut 11, and the slider nut 11 is connected to the screw mechanism 9. The driving motor 6 is arranged on the air duct 4. The driving motor 6 is also arranged on the skylight glass 1. The driving motor 6 can be installed on the outer wall of the air duct 4 and fixed by a bracket so that the motor body 13 is closely fitted with the outer surface of the air duct 4. A motor mounting seat can be provided at the edge or corner of the skylight glass 1 to install the driving motor 6.

[0037] In some preferred embodiments of the present invention, initially, the channels between the air duct outlet 5 and the heat dissipation cavity 2 in the driver's seat, co-driver's seat, left side of the rear row, and right side of the rear row are all closed. When cooling is required, the drive motor 6 is started to drive the screw mechanism 9 to rotate clockwise, and the screw mechanism 9 drives the slider nut 11 on the second slider 12 to move. Since the rotational motion of the screw mechanism 9 can be converted into the linear motion of the slider nut 11, that is, converted into the linear motion of the second slider 12, the second slider 12 slides downward under the drive of the screw mechanism 9, so that the channel between the air duct outlet 5 and the heat dissipation cavity 2 is opened, so that the cold air generated by the air-conditioning system can pass through the air duct 4 and the air duct outlet 5, smoothly enter the heat dissipation cavity 2, and then be discharged from the air outlet holes 3 evenly distributed on the heat dissipation cavity 2, so as to achieve cooling of the driver's seat, co-driver's seat, left side of the rear row, and right side of the rear row.

[0038] When the right side area of ​​the rear row does not need to be cooled, the drive motor 6 is started, driving the screw mechanism 9 to rotate counterclockwise, and the screw mechanism 9 drives the slider nut 11 on the second slider 12 of the independent heat dissipation cavity 2 of the right side area of ​​the rear row to move. Since the rotational motion of the screw mechanism 9 can be converted into the linear motion of the slider nut 11, and then into the linear motion of the second slider 12, the second slider 12 moves upward under the drive of the screw mechanism 9, so that the passage between the air duct outlet 5 and the heat dissipation cavity 2 of the right side area of ​​the rear row is closed, and the cold air in the air duct 4 of the right side area of ​​the rear row cannot enter the heat dissipation cavity 2 through the air duct outlet 5. The cold air can only enter other independent heat dissipation cavities 2 through the air duct outlet 5 of other areas that are not closed, so that the cooling of the right side area of ​​the rear row stops. When all areas do not need to be cooled, all the second sliders 12 are moved upward, the passage between the air duct outlet 5 and the heat dissipation cavity 2 is closed, and the cold air continues to flow in the air duct 4.

[0039] In some preferred embodiments of the present invention, the present invention further provides a vehicle roof, including a vehicle roof body, wherein the vehicle roof body includes the above-mentioned zoned cooling skylight glass structure.

[0040] In some preferred embodiments of the present invention, the present invention further provides a vehicle, comprising the above-mentioned roof.
