[0034] The following refers to Figures 1 - 4 Describe the roof structure 100 according to an embodiment of the present invention. By providing an installation sink 11 in the roof outer shell 1 and installing the photovoltaic panel 2 and the protective layer 3 in the installation sink 11, the integrated setting of the photovoltaic panel 2, the protective layer 3, and the roof outer shell 1 can be achieved. Compared with directly installing the photovoltaic panel 2 on the top of the roof outer shell 1, the roof structure 100 of this embodiment can reduce the thickness of the overall roof, thereby reducing the wind resistance coefficient and wind noise during driving, achieving energy conservation and emission reduction, improving energy efficiency and driving range, and also enhancing the driving comfort of the vehicle. And through the protective layer 3, the sealing protection of the photovoltaic panel 2 can be realized, reducing the failure rate to improve the working stability of the photovoltaic panel 2.

[0035] As Figures 1 - 4 shown, the roof structure 100 according to an embodiment of the present invention includes: a roof outer shell 1, a photovoltaic panel 2, and a protective layer 3.

[0036] On the upper side of the roof outer shell 1, there is a downwardly recessed mounting sink 11 formed. At least one photovoltaic panel 2 is installed in the mounting sink 11, and a protective layer 3 covers the upper side of at least one photovoltaic panel 2. The protective layer 3 is made of a transparent material.

[0037] Specifically, the roof structure 100 is located at the top of the vehicle. The roof structure 100 includes a roof outer shell 1, which is also called a roof cover and is a covering part at the top of the vehicle. Among them, the roof structure 100 is connected to the top of the vehicle body through the roof outer shell 1, which can fix and support the space above the vehicle body to a certain extent. Through the roof outer shell 1, it can protect the passengers in the vehicle from direct sunlight, rain and dust intrusion, providing a more comfortable and clean riding environment for the drivers and passengers. And the roof outer shell 1 also has certain sound insulation and heat insulation effects, which can effectively isolate external noise and heat, improving the comfort and quietness of riding in the vehicle.

[0038] The roof structure 100 also includes a photovoltaic panel 2. The photovoltaic panel 2 is a solar panel. The photovoltaic panel 2 is a power generation device that generates direct current when exposed to sunlight. After installing the photovoltaic panel 2 on the roof of a specific vehicle model, solar energy can be converted into electrical energy, which can be directly charged to the power source carried by the vehicle after being adjusted and stabilized by a controller and an inverter. On the upper side of the roof outer shell 1, there is a downwardly recessed mounting sink 11 formed for the installation of the photovoltaic panel 2. Among them, the mounting sink 11 is configured to be open and open upward, and the photovoltaic panel 2 is at least one. At least one photovoltaic panel 2 is installed in the mounting sink 11, enabling the photovoltaic panel 2 to be installed in the roof outer shell 1, realizing the integrated setting of the photovoltaic panel 2 and the roof outer shell 1. Among them, the photovoltaic panel 2 can be set to one, two, three, four, etc. And the mounting sink 11 can be configured as a square groove or a circular groove. The size and shape of the mounting sink 11 are not unique and are related to the number and size of the photovoltaic panels 2.

[0039] Among them, the photovoltaic panel 2 and the mounting sink 11 can be connected by bonding, clamping or bolts and other connection methods.

[0040] And the roof structure 100 also includes a protective layer 3. The protective layer 3 is also installed in the mounting sink 11, and the protective layer 3 covers the upper side of each photovoltaic panel 2, which can close the mounting sink 11, realizing the shielding and protection of the photovoltaic panel 2, and can prevent the photovoltaic panel 2 from being invaded by external wind, rain, sand and gravel. And the protective layer 3 is made of a transparent material. Among them, the transparent material is a material with extremely high light transmittance, such as glass, transparent acrylic board or transparent plastic, etc. Covering the transparent protective layer 3 on the upper side of each photovoltaic panel 2, in this way, while protecting the photovoltaic panel 2, normal daylighting can also be carried out, ensuring the normal operation of the photovoltaic panel 2.

[0041] Among them, for existing vehicles, the photovoltaic panel 2 is not installed on the roof when leaving the factory. Therefore, the common method adopted by most vehicle owners and modification factories is to first drill holes in the original roof and then fix the finished photovoltaic panel 2 on the holes of the roof through metal brackets. Its shape is irregular, and it increases the thickness of the roof structure 100, damaging the smoothness and integrity of the original roof. It will also significantly increase the wind resistance coefficient and wind noise during vehicle driving, indirectly increasing the energy consumption per kilometer during vehicle driving. Secondly, drilling holes in the roof and installing brackets may also lead to water leakage and air leakage due to poor sealing, rusting of the brackets, and the metal brackets and photovoltaic panel 2 are exposed outside, increasing the failure rate and the possibility of traffic accidents caused by the photovoltaic panel 2 falling due to loose screws, leaving potential safety hazards for driving.

[0042] According to the roof structure 100 of the embodiment of the present invention, by providing an installation sink 11 in the roof outer shell 1 and installing the photovoltaic panel 2 and the protective layer 3 in the installation sink 11, the integrated setting of the photovoltaic panel 2, the protective layer 3 and the roof outer shell 1 can be realized. Compared with directly installing the photovoltaic panel 2 on the top of the roof outer shell 1, the roof structure 100 of this embodiment can avoid additional drilling, the installation process is simple and convenient, the thickness of the overall roof can be reduced, thereby reducing the wind resistance coefficient and wind noise during driving, achieving energy conservation and emission reduction, improving energy efficiency and cruising range, and also enhancing the driving comfort and safety of the vehicle. And by sealing and protecting the photovoltaic panel 2 in the roof outer shell 1 through the protective layer 3, the failure rate can be reduced to improve the working stability of the photovoltaic panel 2, and there will be no safety accidents caused by the photovoltaic panel 2 falling, and the driving safety is high.

[0043] In some embodiments, a fixing structure 12 is provided in the installation sink 11, and the photovoltaic panel 2 is fixedly connected to the installation sink 11 through the fixing structure 12.

[0044] Specifically, a fixing structure 12 is provided in the installation sink 11 for installing the photovoltaic panel 2. If the fixing structure 12 is fixedly connected to the installation sink 11, the fixing structure 12 and the installation sink 11 can be connected as a whole. In this way, during installation, first connect the fixing structure 12 to the installation sink 11, and then connect the photovoltaic panel 2 to the fixing structure 12, and the photovoltaic panel 2 can be installed in the installation sink 11.

[0045] Thus, the photovoltaic panel 2 can be fixedly connected to the installation sink 11 through the fixing structure 12, and the adopted fixed connection method can improve the connection strength between the fixing structure 12, the installation sink 11 and the photovoltaic panel 2, and further enhance the connection stability among the three.

[0046] In other embodiments, the photovoltaic panel 2 is detachably connected to the installation sink 11 through a connection structure.

[0047] Specifically, the connection structure is used to install the photovoltaic panel 2. During installation, the photovoltaic panel 2 is detachably connected to the installation sink 11 through the connection structure, and the photovoltaic panel 2 can be installed in the installation sink 11. Among them, the connection structure can be a fastener such as a bolt. The photovoltaic panel 2 is detachably connected to the installation sink 11 through the bolt. This connection method can improve the connection strength between the fixing structure 12, the installation sink 11 and the photovoltaic panel 2, thereby enhancing the connection stability among the three. Moreover, the bolt connection can make the connection between the fixing structure 12 and the installation sink 11 simpler and more convenient, and the fixing structure 12 and the installation sink 11 can be disassembled, facilitating their subsequent disassembly, assembly and maintenance.

[0048] Thus, through the above two methods, the reliable installation of the photovoltaic panel 2 in the installation sink 11 can be achieved. In this way, when the vehicle is driving, the structure of the photovoltaic panel 2 is stable, and it is not easy to have position offset or looseness, which can improve the stability of the electric energy conversion of the photovoltaic panel 2 and extend the service life of the photovoltaic panel 2.

[0049] In some embodiments, the fixing structure 12 is configured as a fixing glue provided on the inner bottom wall 111 of the installation sink 11, and the photovoltaic panel 2 is fixedly bonded to the fixing glue.

[0050] Specifically, the fixing structure 12 can be configured as a fixing glue, and the fixing glue has strong viscosity to realize the connection and fixation of two or more objects. As Figure 1 and Figure 3 shown, the fixing glue is connected to the inner bottom wall 111 of the installation sink 11, and the photovoltaic panel 2 is connected to the upper side of the fixing glue, so as to realize the bonding of the photovoltaic panel 2 and the inner bottom wall 111 of the installation sink 11. Among them, the photovoltaic panel 2 can be configured as a square structure, and the fixing glue is distributed around the photovoltaic panel 2, so that the four sides of the photovoltaic panel 2 can be bonded to the installation sink 11, improving the connection uniformity and reliability of the photovoltaic panel 2. And the number of the photovoltaic panels 2 is at least one, and the number of the fixing glues matches the number of the photovoltaic panels 2.

[0051] In practical applications, first evenly apply the fixing glue on the inner bottom wall 111 of the installation sink 11, then place the photovoltaic panel 2 on the glue and press it tightly. After the fixing glue is cured and air-dried, the connection between the photovoltaic panel 2 and the installation sink 11 is realized, so as to realize the fixed connection between the photovoltaic panel 2 and the roof shell 1.

[0052] Thus, the photovoltaic panel 2 is fixedly connected to the roof shell 1 through the fixing glue, which can effectively prevent the position of the photovoltaic panel 2 from shifting and deviating, improve the installation accuracy, and ensure the stable and reliable operation of the photovoltaic panel 2. And the connection method is simple and the assembly is convenient.

[0053] In some embodiments, the connection structure is configured as a connecting piece. A first connection hole is provided in the installation sink 11, and a second connection hole is provided in the photovoltaic panel 2. The connecting piece passes through the first connection hole and the second connection hole.

[0054] Specifically, the connecting member can be a connecting bolt. The first connecting hole provided in the installation sink 11 can be configured as a threaded hole, and the second connecting hole provided in the photovoltaic panel 2 can be configured as a round hole, a long hole, etc. The first connecting hole and the second connecting hole are correspondingly distributed, so that the connecting member can be sequentially passed through the first connecting hole and the second connecting hole.

[0055] In actual design, the reserved screw hole positions, that is, the reserved first connecting holes, can be pre-designed on the inner bottom wall 111 of the installation sink 11 of the roof outer shell 1, and a metal skeleton support with corresponding screw hole positions is provided inside the roof outer shell 1. In this way, during installation, the photovoltaic panel 2 is placed in the installation sink 11, and after the second connecting hole is aligned with the first connecting hole, the connecting bolt is sequentially passed through the second connecting hole and the first connecting hole, and after the connecting bolt is tightened, the connection between the photovoltaic panel 2 and the installation sink 11 is completed, so as to realize the connection between the photovoltaic panel 2 and the roof outer shell 1. Its connection method is simple, convenient to install, and easy to disassemble and maintain.

[0056] Among them, the first connecting hole and the second connecting hole can be respectively set as multiple, and the photovoltaic panel 2 and the inner bottom wall 111 are connected at multiple positions through multiple connecting bolts to improve the connection strength and stability between the two.

[0057] Moreover, through bolt connection, the setting of the fixing glue can be omitted, that is, the setting of the fixing glue and the connecting member can be selected alternatively, and the setting method is not limited and can be flexibly selected.

[0058] In addition, the connecting member can also be configured as the combined use of a positioning pin and a bolt, which can also realize the reliable connection between the photovoltaic panel 2 and the inner bottom wall 111.

[0059] Among them, by connecting the photovoltaic panel 2 with the installation sink 11 through the above-mentioned fixing structure 12 or connecting structure, the connection by a general metal bracket can be cancelled, avoiding additional drilling, thereby solving the problems of rain leakage, wind leakage, rust, and increasing the weight of the roof.

[0060] In some embodiments, there are multiple photovoltaic panels 2, and the multiple photovoltaic panels 2 are spaced apart and distributed in the installation sink 11. Among them, the number of photovoltaic panels 2 can be two, three, four, five, etc., and the number of photovoltaic panels 2 is not limited, and it is selectively set according to the space of the roof outer shell 1 and the power conversion efficiency. And the multiple photovoltaic panels 2 are spaced apart. For example, the spacing between two adjacent photovoltaic panels 2 is the same, which can make the photovoltaic panels 2 evenly distributed in the installation sink 11, save space, facilitate arranging more photovoltaic panels 2 to improve the power conversion efficiency of the photovoltaic panels 2, and with such a setting, the multiple photovoltaic panels 2 can be neatly and orderly distributed in the installation sink 11.

[0061] Thus, by arranging multiple photovoltaic panels 2 at intervals, the possibility of light reflection between the photovoltaic panels 2 can be reduced, thereby improving the energy conversion efficiency of the photovoltaic panels 2. Moreover, arranging them at intervals can achieve heat dissipation between the photovoltaic panels 2, so as to improve the safety and stability of the photovoltaic panels 2.

[0062] Furthermore, the interval distances between two adjacent photovoltaic panels 2 can be set differently, which can be flexibly set according to actual usage requirements.

[0063] In some embodiments, multiple photovoltaic panels 2 are distributed at intervals along the first direction and / or the second direction. The first direction is along the front-rear direction of the vehicle, and the second direction is along the left-right direction of the vehicle.

[0064] Specifically, multiple photovoltaic panels 2 can be distributed at intervals only along the front-rear direction of the vehicle, which can make multiple photovoltaic panels 2 occupy the front-rear space of the roof outer shell 1. And multiple photovoltaic panels 2 can be distributed at intervals only along the left-right direction of the vehicle, which can make multiple photovoltaic panels 2 occupy the left-right space of the roof outer shell 1. In addition, multiple photovoltaic panels 2 can be distributed at intervals along the left-right direction and the front-rear direction of the vehicle respectively, which can make multiple photovoltaic panels 2 occupy the left-right space and the front-rear space of the roof outer shell 1. In actual design, the installation space of the installation sink 11 matches the number of photovoltaic panels 2, and the number of photovoltaic panels 2 depends on the space size of the roof outer shell 1.

[0065] Among them, the installation sink 11 can be set to one, two, three, etc., which can be flexibly selected according to actual needs, so as to set an appropriate number of installation sinks 11 on the roof outer shell 1. And arranging more photovoltaic panels 2 in the installation sink 11 can improve the unit electric energy conversion efficiency of multiple photovoltaic panels 2, increase the total electric energy output value of the photovoltaic panels 2, so as to improve the charging efficiency of the photovoltaic panels 2 for the internal power supply of the vehicle.

[0066] Exemplarily, as Figure 2 and Figure 4 shown, there are three photovoltaic panels 2 and one installation sink 11, and the three photovoltaic panels 2 are evenly distributed at intervals along the front-rear direction of the vehicle.

[0067] In addition, arranging multiple photovoltaic panels 2 at intervals along the left-right direction and the front-rear direction of the vehicle respectively can make the number of photovoltaic panels 2 more, which is beneficial to generate more electric energy.

[0068] In some other embodiments, the photovoltaic panel 2 is connected with a photovoltaic panel wire harness 21, and the photovoltaic panel wire harnesses 21 of multiple photovoltaic panels 2 are all converged and connected to the main connection wire harness.

[0069] Specifically, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, a photovoltaic panel harness 21 is connected to the outer periphery of each photovoltaic panel 2. The photovoltaic panel harnesses 21 of multiple photovoltaic panels 2 are distributed in the same direction. In this way, the photovoltaic panel harnesses 21 are arranged at the edges of the photovoltaic panels 2, and the photovoltaic panel harnesses 21 of multiple photovoltaic panels 2 are gathered and connected to the main connection harness, making the circuit layout neat and orderly, which is conducive to the later arrangement and maintenance of the circuits. Moreover, the multiple photovoltaic panel harnesses 21 are neatly distributed, making the occupied space smaller and saving more overall layout space of the photovoltaic panels 2.

[0070] Among them, a wire passing hole is provided in the installation sink 11 for the passage of the photovoltaic panel harness 21. The photovoltaic panel harness 21 passes through the wire passing hole and is electrically connected to the power supply or equipment inside the vehicle body. Thus, through the photovoltaic panel harness 21, the photovoltaic panel 2 can be connected to an inverter or some load devices, and the electric energy converted by the photovoltaic panel 2 can be transmitted to the inverter or load devices through the photovoltaic panel harness 21 to realize the utilization of electric energy.

[0071] In some embodiments, a seal 13 is provided between the protective layer 3 and the roof outer shell 1, and the seal 13 is arranged around the installation sink 11.

[0072] Specifically, the seal 13 can be configured as a sealant. The sealant has strong adhesiveness to realize the connection and fixation of two or multiple objects. The sealant is arranged around the installation sink 11 and is located on the outer periphery of multiple photovoltaic panels 2. In this way, the protective layer 3 and the roof outer shell 1 are adhesively bonded through the seal 13. Among them, the distribution shape of the sealant is matched with the shape of the protective layer 3, and the four sides of the protective layer 3 can be adhesively bonded to the sealant, making the fitting flatness of the protective layer 3 good and improving the connection uniformity and reliability of the protective layer 3.

[0073] Thus, the protective layer 3 is connected to the roof outer shell 1 through the seal 13, making the connection between the roof outer shell 1 and the protective layer 3 tight to realize the sealing of the photovoltaic panel 2, which can prevent the photovoltaic panel 2 from being damaged by external wind, rain, sand and gravel, and ensure the stable and reliable operation of the photovoltaic panel 2. And the connection method is simple and the assembly is convenient.

[0074] Among them, it should be noted that the protective layer 3 can also be made of a clear adhesive with a high light transmittance. The clear adhesive is filled in the installation sink 11 of the roof outer shell 1 in a fluid state until the installation sink 11 is filled up to the top of the installation groove. After the clear adhesive dries and solidifies, the photovoltaic panel 2 is enclosed in the clear adhesive, which can not only play a protective role but also assist in fixing the photovoltaic panel 2, and does not affect the photovoltaic panel 2's collection of solar energy. When directly using the clear adhesive to seal the installation sink 11, the setting of the seal 13 can be reduced.

[0075] In some embodiments, an annular installation sink platform 14 is formed on the inner side wall 112 of the installation sink 11, and the seal 13 is supported on the installation sink platform 14.

[0076] Specifically, an installation sink 14 is provided on the inner side wall 112 of the installation sink 11. The installation sink 14 forms a support surface for the installation of the seal 13. The installation sink 14 is configured as a ring and is distributed around the installation sink 11, enabling the seal 13 to be distributed in a circle around the circumference of the installation sink 11. Moreover, the height of the support surface of the installation sink 14 is equal to or higher than the upper surface of the photovoltaic panel 2. In this way, the protective layer 3 can be installed above the photovoltaic panel 2 through the seal 13 to achieve the installation of the protective layer 3. And the structure of the installation sink 14 is simple and convenient to process.

[0077] In practical applications, first, sealant is evenly applied in a ring around the installation sink 14, and then the protective layer 3 is placed on the sealant and pressed tightly. After the sealant cures and dries, the connection between the protective layer 3 and the installation sink 14 is achieved, so as to realize the sealed connection between the protective layer 3 and the roof outer shell 1.

[0078] Thus, by providing the installation sink 14, the installation of the seal 13 can be made more firm and stable. Furthermore, the connection strength and stability between the protective layer 3 and the roof outer shell 1 can be improved, thereby enhancing the sealing effect of the protective layer 3 on the installation sink 11.

[0079] In some other embodiments, a ring-shaped avoidance groove 31 is formed on the side of the protective layer 3 facing the installation sink 11, and at least part of the seal 13 is received in the avoidance groove 31.

[0080] Specifically, the avoidance groove 31 is configured as a ring and is distributed around the protective layer 3. The avoidance groove 31 is arranged corresponding to the installation sink 14, which is conducive to the seal 13 being received in the avoidance groove 31.

[0081] As Figure 3 shown, in the up-down direction, the avoidance groove 31 is configured to be recessed upward from the lower side of the protective layer 3, enabling the side of the avoidance groove 31 facing the installation sink 11 to be open, and forming an upward accommodation space in the protective layer 3, so that at least part of the seal 13 can be received in the avoidance groove 31 to achieve the connection between the protective layer 3 and the seal 13. Among them, the avoidance groove 31 is processed by cutting, and its structure is simple and convenient to process.

[0082] Thus, through the avoidance groove 31, the connection between the protective layer 3 and the seal 13 of the installation sink 14 can be realized. The distance between the avoidance groove 31 and the installation sink 14 can be increased. The increased distance can enlarge the accommodation space of the seal 13. Compared with the flat-structured protective layer 3, the filling amount of the seal 13 can be increased. Furthermore, the connection strength between the protective layer 3 and the installation sink 14 can be improved, thereby enhancing the sealing effect of the protective layer 3 on the installation sink 11 and extending the service life of the photovoltaic panel 2.

[0083] In some embodiments, the installation sink 11 has an inner bottom wall 111 and an inner side wall 112. The inner side wall 112 is distributed around the inner bottom wall 111. At least a part of the inner side wall 112 is configured to be inclined upward and outward relative to the inner bottom wall 111, that is, some structures on the upper part of the inner side wall 112 can be configured to extend upward and outward relative to the inner bottom wall 111, and some structures of the inner side wall 112 close to the inner bottom wall 111 can extend vertically upward. In this way, it is convenient for the processing and demolding of the mold, and the processing efficiency can be improved.

[0084] Specifically, the roof outer shell 1 is generally made of metal or composite materials. The installation sink 11 can be arranged at the middle position of the roof outer shell 1, and the depth of the installation sink 11 in the up-down direction can be set to 1-3 cm. The inner bottom wall 111 matches the shape of the roof outer shell 1. Generally, most of the roof outer shells 1 are curved surface structures. Correspondingly, the inner bottom wall 111 is configured as a curved surface structure. As Figure 3 and Figure 4 shown, the inner bottom wall 111 is set as a plane for easy understanding. The inner side wall 112 is distributed around the inner bottom wall 111. The inner side wall 112 forms an angle with the inner bottom wall 111, and the angle between the inner side wall 112 and the inner bottom wall 111 is greater than 90 degrees.

[0085] And through the above settings, the opening of the installation sink 11 can be made larger, a larger installation space can be formed, making the installation of the photovoltaic panel 2, the photovoltaic panel wire harness 21 and the protective layer 3 more convenient, and improving the assembly efficiency.

[0086] In other embodiments, the upper surface of the protective layer 3 is flush with the upper surface of the roof outer shell 1. Among them, the upper surface of the protective layer 3 can be set to match the upper surface structure of the roof outer shell 1. In this way, after the protective layer 3 is installed in the installation sink 11, the protective layer 3 and the roof outer shell 1 form an integral structure, so that the top shape of the protective layer 3 matches the top surface shape of the roof outer shell 1. Compared with the traditional fixing method where the bracket protrudes on the upper surface of the roof outer shell 1, the upper surface of the roof structure 100 integrated with the photovoltaic panel 2 can have no protrusions, the roof height will not increase, and thus the wind resistance coefficient during driving will not increase, reducing the vehicle energy consumption. Moreover, the curved surface of the overall roof structure 100 is smooth and smooth, and the wind noise during driving can be reduced, thereby improving the user experience.

[0087] The present invention also proposes a vehicle.

[0088] A vehicle according to an embodiment of the present invention includes the roof structure 100 of any one of the above embodiments. By providing an installation sink 11 in the roof outer shell 1 and installing the photovoltaic panel 2 and the protective layer 3 in the installation sink 11, an integrated setting of the photovoltaic panel 2, the protective layer 3, and the roof outer shell 1 can be achieved. Compared with directly installing the photovoltaic panel 2 on the top of the roof outer shell 1, the roof structure 100 of this embodiment integrates the photovoltaic panel 2 and the protective layer 3 inside the roof outer shell 1, which can reduce the thickness of the overall roof, thereby reducing the wind resistance coefficient and wind noise during driving, achieving energy conservation and emission reduction, improving energy efficiency and driving range, and also enhancing the driving comfort of the vehicle. Moreover, by sealing and protecting the photovoltaic panel 2 inside the roof outer shell 1 through the protective layer 3, the failure rate can be reduced to improve the working stability of the photovoltaic panel 2, and there will be no safety accidents caused by the falling of the photovoltaic panel 2, so the driving safety is high.
