[0037] Specifically, the roof structure 100 is located on the top of the vehicle, and the roof structure 100 includes a roof shell 1, which is also called a roof cover, and is a covering piece on the top of the vehicle. The roof structure 100 is connected to the top of the vehicle body through the roof shell 1, and can fix and support the space on the upper side of the vehicle body, and can protect the passengers in the vehicle from direct sunlight, rain and dust, so as to provide a more comfortable and clean driving environment for the passengers.

[0038] The roof structure 100 also includes a photovoltaic panel 2, which is a solar panel. The photovoltaic panel 2 is a power generation device that generates direct current when exposed to sunlight. When the photovoltaic panel 2 is installed on the roof of a specific vehicle model, it can convert solar energy into electrical energy, which can be directly charged to the power supply carried by the vehicle after being adjusted and stabilized by the controller and the inverter.

Covering the transparent protective layer 3 on the upper side of each photovoltaic panel 2 can protect the photovoltaic panel 2 while allowing normal lighting, so as to ensure the normal operation of the photovoltaic panel 2.

[0041] The existing vehicle is not provided with the photovoltaic panel 2 on the roof when leaving the factory, so the common method adopted by most vehicle owners and modification factories is to punch a hole on the original roof, and then fix the finished photovoltaic panel 2 on the hole on the roof through the metal support, the shape is irregular, and the thickness of the roof structure 100 is increased, the smoothness and integrity of the original roof are damaged, and the wind resistance coefficient and wind noise during driving of the vehicle are obviously increased, and the energy consumption per kilometer during driving of the vehicle is indirectly increased. In addition, the installation of the support through the hole on the roof may cause water leakage and air leakage due to poor sealing, rust of the support, and the metal support and the photovoltaic panel 2 are exposed outside, which increases the failure rate and the possibility of traffic accidents caused by falling of the photovoltaic panel 2 due to loosening of the screws, and hidden dangers are left for driving safety.

[0042] According to the roof structure 100 of the embodiment of the utility model, the mounting groove 11 is arranged on the roof shell 1, the photovoltaic panel 2 and the protective layer 3 are mounted in the mounting groove 11, the integrated arrangement of the photovoltaic panel 2, the protective layer 3 and the roof shell 1 can be realized, compared with directly mounting the photovoltaic panel 2 on the top of the roof shell 1, the roof structure 100 of the embodiment can avoid additional punching, the mounting process is simple and convenient, the thickness of the overall roof can be reduced, and the wind resistance coefficient and wind noise during driving are reduced, energy saving and emission reduction are realized, energy efficiency and cruising range are improved, and driving comfort and safety of the vehicle are improved.

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

[0044] Specifically, the mounting groove 11 is provided with a fixing structure 12 for mounting the photovoltaic panel 2. The fixing structure 12 is fixedly connected in the mounting groove 11, so that the fixing structure 12 is integrated with the mounting groove 11. In this way, during installation, the fixing structure 12 is connected with the mounting groove 11, and then the photovoltaic panel 2 is connected with the fixing structure 12, so that the photovoltaic panel 2 is mounted in the mounting groove 11.

[0045] Therefore, the photovoltaic panel 2 is fixedly connected in the mounting groove 11 through the fixing structure 12, and the fixing connection mode adopted can improve the connection strength of the fixing structure 12 with the mounting groove 11 and the photovoltaic panel 2, and further improve the connection stability among them.

[0046] In other embodiments, the photovoltaic panel 2 is detachably connected in the mounting groove 11 through a connecting structure.

[0047] Specifically, the connecting structure is used to install the photovoltaic panel 2, and the photovoltaic panel 2 is detachably connected with the installation groove 11 through the connecting structure during installation, and the photovoltaic panel 2 can be installed in the installation groove 11. The connecting structure can be a fastener such as a bolt, and the photovoltaic panel 2 is detachably connected in the installation groove 11 through the bolt. The connection mode can improve the connection strength of the fixing structure 12, the installation groove 11 and the photovoltaic panel 2, and further improve the connection stability among the three. In addition, the bolt connection can make the connection of the fixing structure 12 and the installation groove 11 simpler and more convenient, and the fixing structure 12 and the installation groove 11 can be detached, which is convenient for subsequent disassembly and maintenance of the two.

[0048] Therefore, through the above two ways, the photovoltaic panel 2 can be reliably installed in the installation groove 11. In this way, during driving of the vehicle, the structure of the photovoltaic panel 2 is stable and is not easy to deviate or loosen, which can improve the stability of the electric energy conversion of the photovoltaic panel 2 and prolong 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 groove 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, which has strong adhesion to realize the connection and fixation of two objects or multiple objects. Figure 1 and Figure 3 As shown in the figures, the fixing glue is connected to the inner bottom wall 111 of the installation groove 11, and the photovoltaic panel 2 is connected to the upper side of the fixing glue to realize the bonding of the photovoltaic panel 2 and the inner bottom wall 111 of the installation groove 11. The photovoltaic panel 2 can be configured as a square structure, and the fixing glue is distributed around the photovoltaic panel 2 to bond the photovoltaic panel 2 and the installation groove 11 around, which improves the connection uniformity and reliability of the photovoltaic panel 2. In addition, the number of the photovoltaic panel 2 is at least one, and the number of the fixing glue matches the number of the photovoltaic panel 2.

[0051] In actual application, the fixing glue is evenly applied on the inner bottom wall 111 of the installation groove 11, and then the photovoltaic panel 2 is placed on the glue and pressed tightly. After the fixing glue is cured and dried, the connection between the photovoltaic panel 2 and the installation groove 11 is realized to realize the fixed connection between the photovoltaic panel 2 and the roof shell 1.

[0052] Therefore, the photovoltaic panel 2 is fixedly connected with the roof shell 1 through the fixing glue, which can effectively prevent the position of the photovoltaic panel 2 from deviating and improve the installation accuracy to ensure the stable and reliable work of the photovoltaic panel 2. In addition, the connection mode is simple and convenient to assemble.

[0053] In some embodiments, the connecting structure is configured as a connecting piece, the installation groove 11 is provided with a first connecting hole, the photovoltaic panel 2 is provided with a second connecting hole, and the connecting piece is arranged in the first connecting hole and the second connecting hole.

[0054] Specifically, the connecting piece can be a connecting bolt, the first connecting hole provided in the mounting recess 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, or the like. The first connecting hole and the second connecting hole are correspondingly distributed, so that the connecting piece can be sequentially arranged in the first connecting hole and the second connecting hole.

[0055] In actual design, a reserved screw hole can be designed in the inner bottom wall 111 of the mounting recess 11 of the roof shell 1, that is, a first connecting hole is reserved, and a corresponding metal framework support with a screw hole is arranged inside the roof shell 1. In this way, when installing, the photovoltaic panel 2 is placed in the mounting recess 11 and aligned with the second connecting hole and the first connecting hole, and then the connecting bolt is sequentially arranged in the second connecting hole and the first connecting hole, and the connection between the photovoltaic panel 2 and the mounting recess 11 is completed after the connecting bolt is locked, so as to realize the connection between the photovoltaic panel 2 and the roof shell 1. The connection method is simple, convenient to install, and easy to disassemble, maintain.

[0056] The first connecting hole and the second connecting hole can be respectively provided as a plurality of holes, and a plurality of connecting bolts are used to connect the photovoltaic panel 2 and the inner bottom wall 111 at multiple positions, so as to improve the connection strength and stability of the photovoltaic panel 2 and the inner bottom wall 111.

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

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

[0059] The photovoltaic panel 2 and the mounting recess 11 are connected through the fixing structure 12 or the connecting structure, the general metal support connection can be cancelled, additional punching can be avoided, and the problems of rain leakage, air leakage, rust, and increased weight of the roof can be solved.

[0060] In some embodiments, the photovoltaic panel 2 is a plurality of photovoltaic panels 2, and the plurality of photovoltaic panels 2 are spaced apart and arranged in the mounting recess 11. The number of photovoltaic panels 2 is not limited and can be selected according to the space of the roof shell 1 and the electrical energy conversion rate. The plurality of photovoltaic panels 2 are spaced apart, for example, the interval distance between two adjacent photovoltaic panels 2 is the same, so that the photovoltaic panels 2 are evenly distributed in the mounting recess 11, the space can be saved, more photovoltaic panels 2 can be arranged, the electrical energy conversion efficiency of the photovoltaic panels 2 can be improved, and the plurality of photovoltaic panels 2 can be arranged in the mounting recess 11 in an orderly manner.

[0061] Therefore, by arranging the plurality of photovoltaic panels 2 spaced apart, the possibility of light reflection between the photovoltaic panels 2 can be reduced, thereby improving the energy conversion efficiency of the photovoltaic panels 2, and the spacing apart can achieve heat dissipation between the photovoltaic panels 2, thereby improving the safety and stability of the photovoltaic panels 2.

[0062] In addition, the spacing distance between the two adjacent photovoltaic panels 2 can be different, which can be flexibly set according to actual use requirements.

[0063] In some embodiments, the plurality of photovoltaic panels 2 are distributed spaced apart along a first direction and / or a second direction, the first direction being along the front-rear direction of the vehicle, and the second direction being along the left-right direction of the vehicle.

[0064] Specifically, the plurality of photovoltaic panels 2 can be distributed spaced apart only along the front-rear direction of the vehicle, so that the plurality of photovoltaic panels 2 occupy the front-rear space of the roof shell 1, and the plurality of photovoltaic panels 2 can be distributed spaced apart only along the left-right direction of the vehicle, so that the plurality of photovoltaic panels 2 occupy the left-right space of the roof shell 1, and the plurality of photovoltaic panels 2 can be distributed spaced apart along the left-right direction and the front-rear direction of the vehicle, respectively, so that the plurality of photovoltaic panels 2 occupy the left-right space and the front-rear space of the roof shell 1. In actual design, the setting space of the mounting recess 11 matches the number of photovoltaic panels 2, and the number of photovoltaic panels 2 depends on the size of the space of the roof shell 1.

[0065] The mounting recess 11 can be one, two, three, etc., which can be flexibly selected according to actual requirements, so that a proper number of mounting recesses 11 can be arranged on the roof shell 1, and a larger number of photovoltaic panels 2 can be arranged in the mounting recess 11, thereby improving the unit electric energy conversion efficiency of the plurality of photovoltaic panels 2, increasing the total electric energy output of the photovoltaic panels 2, and improving the charging efficiency of the photovoltaic panels 2 on the internal power supply of the vehicle.

[0066] For example, as shown in Figure 2 and Figure 4 , the photovoltaic panels 2 are three, the mounting recess 11 is one, and the three photovoltaic panels 2 are evenly distributed spaced apart along the front-rear direction of the vehicle.

[0067] In addition, the plurality of photovoltaic panels 2 are distributed spaced apart along the left-right direction and the front-rear direction of the vehicle, respectively, so that the number of photovoltaic panels 2 is larger, which is beneficial to generate more electric energy.

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

[0069] Specifically, as shown in Figure 1 , Figure 2 and Figure 4 , the photovoltaic panel wire harness 21 of each photovoltaic panel 2 is connected to the total connection wire harness through a connection wire harness 22.As shown, the outer periphery of each photovoltaic panel 2 is connected with a photovoltaic panel wire harness 21, and the photovoltaic panel wire harnesses 21 of the plurality of photovoltaic panels 2 are distributed in the same direction. In this way, the photovoltaic panel wire harnesses 21 are arranged at the edges of the photovoltaic panels 2, and the photovoltaic panel wire harnesses 21 of the plurality of photovoltaic panels 2 are connected to the total connection wire harness in a concentrated manner. As a result, the lines are arranged in an orderly and sequential manner, which facilitates the arrangement and maintenance of the lines in the later stage. In addition, the plurality of photovoltaic panel wire harnesses 21 are distributed in an orderly manner, so that the occupied space is smaller, and the overall arrangement space of the photovoltaic panels 2 is saved.

[0070] In the mounting groove 11, a threading hole is arranged for the passage of the photovoltaic panel wire harness 21. The photovoltaic panel wire harness 21 is electrically connected to the power supply or equipment inside the vehicle body through the threading hole. In this way, the photovoltaic panel 2 can be connected to the inverter or some load equipment through the photovoltaic panel wire harness 21. The electrical energy converted by the photovoltaic panel 2 can be transmitted to the inverter or load equipment through the photovoltaic panel wire harness 21, so as to realize the utilization of electrical energy.

[0071] In some embodiments, a sealing member 13 is arranged between the protective layer 3 and the roof shell 1, and the sealing member 13 is arranged around the mounting groove 11.

[0072] Specifically, the sealing member 13 can be configured as a sealing glue. The sealing glue has strong adhesion, so as to realize the connection and fixation of two objects or multiple objects. The sealing glue is arranged around the mounting groove 11, and the sealing glue is located at the outer periphery of the plurality of photovoltaic panels 2. In this way, the protective layer 3 is glued to the roof shell 1 through the sealing member 13. The sealing glue is arranged in a distributed shape matching the shape of the protective layer 3. The four sides of the protective layer 3 are glued to the sealing glue. As a result, the flatness of the protective layer 3 is good, and the uniformity and reliability of the connection of the protective layer 3 are improved.

[0073] In this way, the protective layer 3 is connected to the roof shell 1 through the sealing member 13. The connection between the roof shell 1 and the protective layer 3 is tight, so as to realize the sealing of the photovoltaic panel 2. The photovoltaic panel 2 can be prevented from being damaged by external wind, rain, sand and stones. The stable and reliable work of the photovoltaic panel 2 is ensured. In addition, the connection method is simple and convenient to assemble.

[0074] In addition, it should be noted that the protective layer 3 can also be made of clear glue with high light transmittance. The clear glue is filled in the mounting groove 11 of the roof shell 1 in a fluid state, and fills the mounting groove 11 until the top of the mounting groove. After the clear glue is dried and solidified, the photovoltaic panel 2 is enclosed in the clear glue. The clear glue can not only realize the protection function, but also assist in fixing the photovoltaic panel 2. In addition, the clear glue does not affect the collection of solar energy by the photovoltaic panel 2. When the clear glue is used to directly seal the mounting groove 11, the sealing member 13 can be reduced.

[0075] In some embodiments, the inner side wall 112 of the mounting groove 11 is formed with an annular mounting depression 14, and the sealing member 13 is supported on the mounting depression 14.

[0076] Specifically, the inner side wall 112 of the mounting groove 11 is provided with a mounting sink 14, the mounting sink 14 is formed with a support surface for mounting the seal 13, the mounting sink 14 is configured as an annular shape and is distributed around the mounting groove 11, so that the seal 13 can be distributed around the circumference of the mounting groove 11, and the height of the support surface of the mounting sink 14 is equal to or higher than the upper surface of the photovoltaic panel 2, so that the protective layer 3 can be mounted above the photovoltaic panel 2 through the seal 13 to achieve the installation of the protective layer 3. And the structure of the mounting sink 14 is simple and convenient to process.

[0077] In actual application, the sealant is evenly applied on the annular mounting sink 14, and then the protective layer 3 is placed on the sealant and pressed tightly, and after the sealant is cured and dried, the connection between the protective layer 3 and the mounting sink 14 is realized, so as to realize the sealing connection between the protective layer 3 and the roof shell 1.

[0078] Therefore, by arranging the mounting sink 14, the installation of the seal 13 is more firm and stable, and the connection strength and stability between the protective layer 3 and the roof shell 1 can be improved, so as to improve the sealing effect of the protective layer 3 on the mounting groove 11.

[0079] In other embodiments, the side of the protective layer 3 facing the mounting groove 11 is formed with an annular avoiding groove 31, and at least part of the seal 13 is accommodated in the avoiding groove 31.

[0080] Specifically, the avoiding groove 31 is configured as an annular shape and is distributed around the protective layer 3, and the avoiding groove 31 is arranged corresponding to the mounting sink 14, which is beneficial to the accommodation of the seal 13 in the avoiding groove 31.

[0081] As shown in Figure 3 In the up-down direction, the avoiding groove 31 is recessed upward from the lower side of the protective layer 3, so that the avoiding groove 31 is open to the side facing the mounting groove 11, and an accommodating space is formed upward in the protective layer 3, so that at least part of the seal 13 is accommodated in the avoiding groove 31 to realize the connection between the protective layer 3 and the seal 13. The avoiding groove 31 is processed by cutting, which is simple in structure and convenient to process.

[0082] Therefore, the avoiding groove 31 can realize the connection between the protective layer 3 and the seal 13 of the mounting sink 14, the distance between the avoiding groove 31 and the mounting sink 14 can be increased, the accommodating space of the seal 13 can be increased by increasing the distance, the filling amount of the seal 13 can be increased compared with the flat structure of the protective layer 3, and the connection strength between the protective layer 3 and the mounting sink 14 can be improved, so as to improve the sealing effect of the protective layer 3 on the mounting groove 11, and prolong the service life of the photovoltaic panel 2.

[0083] In some embodiments, the mounting groove 11 has an inner bottom wall 111 and inner side walls 112 distributed around the inner bottom wall 111, at least part of the inner side walls 112 is configured to be arranged upward and outward inclined relative to the inner bottom wall 111, that is, the upper part of the inner side walls 112 can be configured to extend upward and outward inclined relative to the inner bottom wall 111, and the part of the inner side walls 112 close to the inner bottom wall 111 can be configured to extend vertically upward, so as to facilitate the processing and demolding of the mold and improve the processing efficiency.
