Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The following is for reference. Figures 1-23 According to an embodiment of the present utility model, the battery pack 101 can transfer solar energy to the battery 4 for the battery 4 to use, thereby replenishing the battery pack 101 with power in a timely manner, preventing the battery pack 101 from running out of power and becoming unusable, and improving the battery pack 101's endurance performance.

[0058] like Figures 1-23 As shown, a battery pack 101 according to an embodiment of the present invention includes: a bottom protective plate 1 and an upper protective plate 2.

[0059] It should be noted that the battery pack 101 of this utility model can be applied to any device or equipment that uses the battery pack 101 to generate electricity, such as vehicles, ships, aircraft, energy storage cabinets, and electric toys. When the battery pack 101 is applied to a vehicle 100, the underbody protection plate 1 can be installed on the top of the vehicle 100, or on the front, rear, or bottom of the vehicle 100, as shown in the attached figure. Figure 1 As shown, this embodiment uses the example of the underbody protection plate 1 being installed on the top of the vehicle 100 for illustration.

[0060] The bottom guard plate 1 serves as both a bottom protection and cooling structure for the battery 4, protecting and cooling the bottom of the battery 4, and also as a top structural component of the vehicle 100. This reduces the number of parts in the vehicle 100, thereby effectively reducing the weight of the vehicle 100. At the same time, it provides temperature control for the interior of the vehicle 100, preventing heat from the battery pack 101 from entering the interior of the vehicle 100 and affecting the interior space. This solves the problems of excessive weight and low temperature regulation rate of the vehicle 100.

[0061] The upper protective plate 2 also protects the battery 4, serving as the upper protective structure for the battery 4 to protect its upper part and prevent damage from external objects or impacts. (Reference) Figure 2 and Figure 4 As shown, the upper protective plate 2 is connected to the upper side of the bottom protective plate 1, and the two are spaced apart by a certain distance. Thus, the upper protective plate 2 and the bottom protective plate 1 together define a space area, namely the battery mounting cavity 31. The battery mounting cavity 31 is used to install the battery 4. That is, the battery 4 is installed in the battery mounting cavity 31 and is wrapped by the bottom protective plate 1 and the upper protective plate 2 to achieve a seal, preventing dust, moisture, foreign objects and other external objects from entering the battery mounting cavity 31 and affecting the battery 4.

[0062] Furthermore, the upper protective plate 2 includes a first solar power generation layer 21, which is electrically connected to the battery 4, meaning that the first solar power generation layer 21 can transfer electrical energy to the battery 4.

[0063] In other words, the upper protective plate 2 can also serve as an energy replenishment component, providing additional power to the battery 4. It absorbs sunlight through the first solar power generation layer 21, converting solar radiation into electrical energy to provide power support for the battery 4. The battery 4 can store the electrical energy transmitted by the first solar power generation layer 21 or use it directly. In other words, the upper protective plate 2 can serve as a power generation component to supply power to the battery pack 101, and also as a protective and sealing component for the battery pack 101, greatly improving the integration of the battery pack 101. Thus, the effective utilization of solar energy is achieved, reducing the electrical energy consumption of the battery 4, thereby allowing the battery pack 101 to be replenished with power in a timely manner, preventing the battery pack 101 from running out of power and becoming unusable, and improving the battery pack 101's endurance.

[0064] In practical design, such as Figure 6As shown, a charging controller 7 can be installed on the bottom protective plate 1. The charging controller 7 is electrically connected to the first solar power generation layer 21. In this way, the charging controller 7 can monitor the current and voltage generated by the first solar power generation layer 21 in real time, convert the unstable current generated by solar energy into a stable current, and monitor the charging and discharging status of the battery pack 101 in real time. Thus, it can intelligently allocate the energy stored in the battery pack 101 and the electrical energy generated by solar energy according to the actual situation and needs. When there is sufficient sunlight, solar energy is used first, and excess electrical energy is stored in the battery pack 101; when there is insufficient sunlight, it automatically switches to the battery pack 101 for power supply, ensuring uninterrupted energy supply, thereby avoiding overcharging and over-discharging of the battery 4, extending the service life of the battery 4, and improving the utilization efficiency of solar energy.

[0065] According to the embodiment of the present utility model, the battery pack 101 is provided with a bottom protective plate 1 and an upper protective plate 2 to protect and seal the battery 4. At the same time, the upper protective plate 2 includes a first solar power generation layer 21, which is electrically connected to the battery 4 and can transfer solar energy to the battery 4 for its use. This allows the battery pack 101 to be replenished with power in a timely manner, preventing the battery pack 101 from running out of power and becoming unusable, thereby improving the battery pack 101's endurance performance.

[0066] In some embodiments, such as Figures 13-16 As shown, the upper protective plate 2 also includes a first top plate layer 22 and a first bottom plate layer 23. A first solar power generation layer 21 is disposed between the first top plate layer 22 and the first bottom plate layer 23. The first bottom plate layer 23 is located on the side of the first solar power generation layer 21 facing into the battery mounting cavity 31, and the first top plate layer 22 is located on the side of the first solar power generation layer 21 facing away from the battery mounting cavity 31. Figure 13 As shown in the vertical direction, the first bottom plate layer 23 is located below the first solar power generation layer 21, and the first top plate layer 22 is located above the first solar power generation layer 21. Thus, the first top plate layer 22 can effectively protect the upper side of the first solar power generation layer 21 and allow sunlight to pass through the first top plate layer 22, so that the first solar power generation layer 21 can absorb sunlight. The first top plate layer 22 can also effectively protect the upper side of the first solar power generation layer 21, thereby achieving the sealing of the first solar power generation layer 21 and preventing it from being damaged.

[0067] In actual design, the first solar power generation layer 21 can be made of silicon wafers and EVA material. The silicon wafers are responsible for converting sunlight into electrical energy. Monocrystalline silicon or polycrystalline silicon can be used. Monocrystalline silicon cells 4 have higher efficiency, while polycrystalline silicon cells 4 have lower cost. The choice can be made flexibly according to the actual situation. EVA material can improve the stability and durability of the first solar power generation layer 21.

[0068] In some embodiments, such as Figures 13-16As shown, the upper protective plate 2 also includes a first frame 24, which is used to support and fix the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23. The shape and size of the first frame 24 are adapted to the shape and size of the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23. Figure 13 The first frame 24 shown is rectangular with a hollow interior. Its outer perimeter dimensions match the dimensions of the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23, so that the outer perimeters of the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23 can all be connected to the first frame 24.

[0069] Of course, the first frame 24 can also be constructed in a circular shape, an irregular shape, etc., to be compatible with the first top plate layer 22, the first solar power generation layer 21 and the first bottom plate layer 23. The first frame 24 can be made of aluminum material and can be flexibly set according to the actual situation, not limited to the one described in this embodiment.

[0070] Thus, the first frame 24 tightly connects the first top plate layer 22, the first solar power generation layer 21 and the first bottom plate layer 23 together to form a stable whole structure, which improves the structural stability and reliability of the upper protective plate 2. At the same time, it effectively ensures the stability and integrity of the first solar power generation layer 21, enabling it to work stably.

[0071] Furthermore, such as Figure 21 As shown, the first frame 24 is connected to the bottom protective plate 1 by means of welding, adhesive bonding, threaded connection, snap-fit ​​connection, etc., thereby achieving a stable connection between the upper protective plate 2 and the bottom protective plate 1, integrating them into one piece, thus providing a reliable external protective structure for the battery 4.

[0072] In practical design, such as Figure 14 and Figure 15 As shown, a first connector 81 extends downwards from the upper protective plate 2 towards the bottom protective plate 1. The first connector 81 can be plugged into the socket of the charging controller 7, thus achieving electrical connection with the charging controller 7, and consequently, electrical connection between the first solar power generation layer 21 and the battery 4. Therefore, as... Figure 7 As shown, the electrical energy generated by the first solar power generation layer 21 can flow into the charging controller 7 through the first connector 81. The charging controller 7 will monitor and adjust the current to ensure that the electrical energy is collected into the distribution box through the connecting copper busbar 85 at an appropriate speed and voltage, and then uniformly distributed by the distribution box.

[0073] In some embodiments, such as Figure 13As shown, the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23 are rectangular in shape, and their dimensions are compatible. The outer periphery of the first top plate layer 22 extends downward to form a first connecting flange 221, the outer periphery of the first solar power generation layer 21 extends downward to form a second connecting flange 211, and the outer periphery of the first bottom plate layer 23 extends downward to form a third connecting flange 231. The first connecting flange 221, the second connecting flange 211, and the third connecting flange 231 are all used to connect and fix to the first frame 24. In practice, as... Figure 16 As shown, the first connecting flange 221 is attached to the outer side of the second connecting flange 211 and is located on the outermost side of the upper guard plate 2, and the third connecting flange 231 is attached to the inner side of the second connecting flange 211 and is located on the innermost side of the upper guard plate 2.

[0074] Furthermore, the first frame 24 has a first insertion slot 241, such as Figure 16 As shown, the upper side of the first frame 24 is recessed to form a first insertion groove 241. The width of the first insertion groove 241 should match the thickness of the overall structure formed by the first connecting flange 221, the second connecting flange 211, and the third connecting flange 231 fitting together. This allows the first connecting flange 221, the second connecting flange 211, and the third connecting flange 231 to be inserted and fixed in the first insertion groove 241, making installation convenient. This achieves the fixation of the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23 on the first frame 24, thereby ensuring a stable connection between the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23, preventing loosening or falling off. Together with the first frame 24, they form a stable and reliable structure, improving the structural strength of the upper protective plate 2 and protecting the battery 4.

[0075] In some embodiments, the first frame 24 is formed with a connecting adhesive groove 242 that opens toward the bottom cover plate 1. The connecting adhesive groove 242 is filled with adhesive 2422. The first frame 24 is attached to the bottom cover plate 1 and fixed by the adhesive 2422.

[0076] Specifically, such as Figure 16 and Figure 21 As shown, a connecting groove 242 is formed on the lower side of the first frame 24, which opens towards the bottom cover plate 1. That is, the connecting groove 242 is open downwards, and adhesive 2422 can be filled into the connecting groove 242 to make the first frame 24 fit with the bottom cover plate 1 and be fixed by the adhesive 2422. This achieves a tight and firm fixation between the first frame 24 and the bottom cover plate 1, preventing the upper cover plate 2 from separating from the bottom cover plate 1. At the same time, it also achieves a seal between the upper cover plate 2 and the bottom cover plate 1, which prevents dust, moisture and other substances from entering the battery mounting cavity 31 through gaps and affecting the operation of the battery 4.

[0077] In actual design, for example, the height of the connecting glue groove 242 can be set to 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, 3mm or other, and the width can be set to 15mm, 16mm, 17mm, 18mm, 20mm or other. It can be flexibly set according to actual needs and is not limited to the embodiment described herein. It is understood that the width and height of the connecting glue groove 242 should be set appropriately to avoid affecting its structural strength.

[0078] In some embodiments, such as Figure 21 and Figure 22 As shown, the battery pack 101 also includes an explosion-proof valve mounting component 5, which is sequentially installed through the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23. That is, the first top plate layer 22, the first solar power generation layer 21, and the first bottom plate layer 23 are all provided with through holes for the explosion-proof valve mounting component 5 to pass through, and the through holes are adapted to the shape and size of the explosion-proof valve mounting component 5, thereby achieving stable installation of the explosion-proof valve mounting component 5.

[0079] Furthermore, such as Figure 22 As shown, the explosion-proof valve mounting component 5 has an explosion-proof valve mounting hole 51 that communicates with the battery mounting cavity 31. The explosion-proof valve mounting hole 51 is used to install the explosion-proof valve 52. Figure 22 The explosion-proof valve mounting hole 51 shown is provided with an internal thread, which can be used to install a threaded explosion-proof valve 52. It is easy to install, disassemble, and replace the explosion-proof valve 52. The explosion-proof valve mounting hole 51 is connected to the battery mounting cavity 31, which allows the gas in the battery mounting cavity 31 to be discharged smoothly through the explosion-proof valve 52.

[0080] Therefore, the battery mounting cavity 31 is connected to the external environment through the explosion-proof valve mounting hole 51, so that the high temperature and high pressure gas in the battery mounting cavity 31 can be smoothly discharged to the external environment through the explosion-proof valve 52. This can effectively prevent the internal pressure or temperature of the battery pack 101 from being too high, thereby extending the service life of the battery pack 101.

[0081] In practical design, such as Figure 21 As shown, a sealing ring 83 can be provided on the part of the explosion-proof valve mounting component 5 located outside the battery mounting cavity 31. The sealing ring 83 can be made of silicone rubber. The sealing ring 83 is sleeved on the outside of the explosion-proof valve mounting component 5 and tightly abuts against the outer peripheral wall of the explosion-proof valve mounting component 5 near the first connecting flange 221. The sealing ring 83 extends radially for a distance to form a sealing surface for tightly abutting against the first connecting flange 221. Thus, the seal between the outside of the explosion-proof valve mounting component 5 and the upper protective plate 2 is achieved, further improving the sealing performance of the battery pack 101.

[0082] Furthermore, the portion of the explosion-proof valve mounting component 5 located outside the battery mounting cavity 31 can be bonded to the third connecting flange 231 via adhesive 2422, thereby achieving a seal between the interior of the explosion-proof valve mounting component 5 and the upper protective plate 2, further improving the sealing performance of the battery pack 101. Thus, the connection between the explosion-proof valve mounting component 5 and the upper protective plate 2 is doubly sealed by the sealing ring 83 and the adhesive 2422, greatly improving the sealing performance of the battery pack 101.

[0083] In some embodiments, the first top plate layer 22 is made of fiberglass.

[0084] Specifically, fiberglass has the characteristics of high strength, light weight, corrosion resistance, and wear resistance. By making the first top plate layer 22 with fiberglass, the strength of the first top plate layer 22 can be improved, the weight of the battery pack 101 can be reduced, and the corrosion of external chemicals can be effectively prevented, thereby effectively protecting the first solar power generation layer 21. At the same time, the fiberglass-made first top plate layer 22 allows sunlight to pass through, thereby ensuring that the first solar power generation layer 21 can absorb sunlight.

[0085] In other embodiments, the first base plate layer 23 is made of high-strength steel.

[0086] Specifically, high-strength steel has extremely high strength and toughness. By using high-strength steel to manufacture the first base plate layer 23, the strength and durability of the first base plate layer 23 can be improved, enabling it to withstand greater impacts, thereby effectively protecting the first solar power generation layer 21 and preventing it from deforming or being damaged.

[0087] Therefore, the structural strength of the upper protective plate 2 can be effectively improved by the first top plate layer 22 made of fiberglass and the first bottom plate layer 23 made of high-strength steel, which helps it resist external impacts and pressure in the battery mounting cavity 31, thereby improving the safety and stability of the battery pack 101.

[0088] In actual design, for example, the thickness of the fiberglass can be set to 1mm, 2mm, 3mm or other, the thickness of the first solar power generation layer 21 can be set to 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or other, and the thickness of the high-strength steel can be set to 1mm, 2mm, 3mm or other. These can be flexibly set according to actual conditions and needs, and are not limited to those described in this embodiment.

[0089] In the actual installation process, the silicon wafer can be placed between the fiberglass and the high-strength steel, and then compacted by filling with EVA material. After that, it is encapsulated with the first frame 24, that is, the fiberglass and the high-strength steel and the first solar power generation layer 21 made of silicon wafer and EVA material are inserted into the first insertion slot 241 of the first frame 24.

[0090] In some embodiments, such as Figure 20 As shown, the bottom protective plate 1 includes a heat equalization plate 11, a flow channel plate 12, and a reinforcing plate 13. The heat equalization plate 11, the flow channel plate 12, and the reinforcing plate 13 are distributed sequentially along the thickness direction of the bottom protective plate 1, i.e. Figure 20 As shown in the top-to-bottom direction, the temperature distribution plate 11, the flow channel plate 12, and the reinforcing plate 13 are distributed sequentially from top to bottom along the bottom guard plate 1. The temperature distribution plate 11 is located at the top, the reinforcing plate 13 is located at the bottom, and the flow channel plate 12 is located between the temperature distribution plate 11 and the reinforcing plate 13.

[0091] Furthermore, the heat spreader 11 is constructed as the bottom wall of the battery mounting cavity 31, that is, the heat spreader 11 can support and fix the battery 4, which can improve the stability of the battery pack 101. At the same time, the heat spreader 11 can effectively distribute the heat generated by the battery 4 evenly, prevent local overheating, and thus improve the performance and safety of the battery 4.

[0092] The heat spreader 11 and the flow channel plate 12 are spaced apart by a certain distance to define the cooling chamber 15. Coolant can flow in the cooling chamber 15 to cool or heat the battery cell, ensuring that the battery cell operates within the normal temperature range. The reinforcing plate 13 is supported at the bottom of the flow channel plate 12. That is, the reinforcing plate 13 can support and fix the heat spreader 11 and the flow channel plate 12, thereby enhancing the structural strength and stability of the bottom protection plate 1 and preventing damage to the battery 4 or other components when the battery pack 101 is impacted, thereby further improving the safety of the battery pack 101.

[0093] In some embodiments, the heat spreader 11 is equipped with a plurality of expansion beams 111, which are spaced apart within the battery mounting cavity 31 and divide the battery mounting cavity 31 into a plurality of sub-mounting cavities 311.

[0094] The heat spreader 11 can be equipped with two, three or even more expansion beams 111. The expansion beams 111 can provide constraint force for the battery cells, which can support and fix the battery cells 4, prevent the cells from shifting, improve the stability of the cells, and thus ensure the cycle life of the cells. At the same time, the expansion beams 111 can also distribute the heat generated by the battery cells and other components more evenly throughout the battery mounting cavity 31, avoiding the occurrence of local overheating.

[0095] Setting multiple expansion beams 111 can improve the constraint force and heat dissipation of the battery cells 4. The multiple expansion beams 111 are distributed at intervals in the battery mounting cavity 31 so that multiple positions of the battery cells can be constrained, and the heat dissipation is more uniform. This allows the battery 4 to be installed stably in the battery mounting cavity 31. The multiple expansion beams 111 divide the battery mounting cavity 31 into multiple sub-mounting cavities 311, and multiple battery cells 4 can be installed in the multiple sub-mounting cavities 311, thereby maintaining the overall orderliness, stability and heat dissipation uniformity of the battery 4.

[0096] Specifically, such as Figure 12 As shown, three expansion beams 111 are provided: one expansion beam 111 is located at the front of the heat spreader 11, one expansion beam 111 is located at the rear of the heat spreader 11, and one expansion beam 111 is located in the middle of the heat spreader 11. The three expansion beams 111 divide the battery mounting cavity 31 into two sub-mounting cavities 311. This allows the battery 4 to be stably mounted on the heat spreader 11.

[0097] In the actual design, the expansion beam 111 can be connected to the heat spreader 11 by brazing or friction stir welding. The heat spreader 11 can also be provided with a mounting panel 112. The mounting panel 112 can provide installation positions for other plug-in components to ensure the normal operation of the battery pack 101. The mounting panel 112 is located in front of the expansion beam 111 and is spaced apart from it. It can be connected to the heat spreader 11 by brazing or friction stir welding to ensure the stability and reliability of its connection.

[0098] In other embodiments, foam material 16 is filled between the flow channel plate 12 and the reinforcing plate 13.

[0099] Specifically, such as Figure 20 As shown, the flow channel plate 12 and the reinforcing plate 13 are spaced apart by a certain distance to form a certain space area. Foam material 16 can be filled in this space area. This can isolate the temperature inside the vehicle from the temperature of the battery pack 101, thereby preventing the temperature of the battery pack 101 from being transferred to the vehicle and preventing the temperature change of the battery pack 101 from affecting the temperature inside the vehicle. At the same time, the foam material 16 can also prevent coolant from leaking into the vehicle, further improving the sealing performance of the battery pack 101.

[0100] This utility model also proposes a vehicle 100.

[0101] The vehicle 100 according to an embodiment of the present invention includes a frame 102 and a battery pack 101 of any of the above embodiments, wherein the battery pack 101 is mounted on the top of the frame 102.

[0102] Specifically, the battery pack 101 is the power source for the vehicle 100, responsible for providing energy storage and power output to ensure the normal operation of the vehicle 100, such as... Figures 1-4As shown, the battery pack 101 is installed on the top of the frame 102, that is, the battery pack 101 is installed at the highest point of the vehicle 100. This not only facilitates the absorption of sunlight by the first solar power generation layer 21, but also avoids the battery pack 101 occupying the bottom space of the vehicle 100. On the one hand, it increases the bottom height of the vehicle 100, improves the passability in complex outdoor road conditions, and solves the problem of bumps and impacts of the battery pack 101 in the traditional vehicle 100 during the use of the vehicle 100. On the other hand, the high-efficiency first solar power generation layer 21 can be used to replenish the energy of the battery pack 101, solving the problem of outdoor energy replenishment. This greatly improves driving convenience and enhances the user experience.

[0103] In some embodiments, the bottom guard plate 1 and / or the upper guard plate 2 are connected to the vehicle frame 102.

[0104] Specifically, the bottom guard plate 1 and the upper guard plate 2 are connected to the frame 102 and are attached to the top of the frame 102. Thus, the bottom guard plate 1 and the upper guard plate 2 can serve as the top structural components of the vehicle 100, reducing the number of parts in the vehicle 100 and improving the integration of the vehicle 100. This effectively reduces the weight of the vehicle 100 while providing temperature control for the interior of the vehicle 100, preventing the heat from the battery pack 101 from entering the interior of the vehicle 100 and affecting the interior space. This solves the problems of excessive weight and low temperature control rate of the vehicle 100.

[0105] In some embodiments, the frame 102 is formed with a mounting groove 1021, and at least a portion of the upper guard plate 2 and at least a portion of the lower guard plate 1 are located within the mounting groove 1021.

[0106] Specifically, such as Figure 5 As shown, a mounting groove 1021 is formed on the top of the frame 102, and the shape and size of the mounting groove 1021 are adapted to the shape and size of the battery pack 101. Figure 5 The mounting slot 1021 shown is a rectangular slot. Of course, it can also be set as a circular slot, an irregular slot, etc., to fit the battery pack 101.

[0107] The entire bottom guard plate 1 is installed in the mounting groove 1021, and the outer periphery of the upper guard plate 2, that is, the first frame 24, is located in the mounting groove 1021. In practice, the upper guard plate 2 and the bottom guard plate 1 can be connected to the mounting groove 1021 by welding to ensure the reliability and stability of the connection between the upper guard plate 2 and the bottom guard plate 1 and the frame 102.

[0108] In practical design, such as Figures 1-4 As shown, protective beams 104 can also be provided on the left and right sides of the battery pack 101 to provide safety protection for the battery pack 101 and prevent damage to the battery pack 101 when the vehicle 100 is impacted during driving.

[0109] In some embodiments, such as Figure 2 , Figures 17-19 As shown, the vehicle 100 also includes a hood 103, which includes a second solar power generation layer 61.

[0110] In other words, the second solar power generation layer 61 can also absorb sunlight and convert solar radiation into electrical energy to provide power support for the battery 4. The battery 4 can store the electrical energy transmitted by the second solar power generation layer 61 or use it directly.

[0111] Therefore, by integrating solar power generation components (i.e., the first solar power generation layer 21 and the second solar power generation layer 61) on the hood 103 and roof of the vehicle 100, which receive the longest sunlight, the usage scenarios and usage time of the vehicle 100 can be effectively improved, the energy shortage anxiety when outdoors or when other refueling is inconvenient can be resolved, and the range performance of the vehicle 100 can be greatly improved.

[0112] In practical design, the second solar power generation layer 61 can be made of silicon wafers and EVA material. The silicon wafers are responsible for converting sunlight into electrical energy. Monocrystalline silicon or polycrystalline silicon can be used. Monocrystalline silicon cells 4 have higher efficiency, while polycrystalline silicon cells 4 have lower cost. The choice can be made flexibly according to the actual situation. EVA material can improve the stability and durability of the second solar power generation layer 61.

[0113] In some embodiments, such as Figures 17-19 and Figure 23 As shown, the naval canopy 103 also includes a second frame 62, a second top plate layer 63, and a second bottom plate layer 64. The second frame 62 is used to support and fix the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64. That is, the shape and size of the second frame 62 are adapted to the shape and size of the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64. Figure 17 The second frame 62 shown is rectangular with a hollow interior. Its outer perimeter dimensions match the dimensions of the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64, so that the outer perimeters of the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64 can be fixedly connected to the second frame 62.

[0114] Of course, the second frame 62 can also be constructed in a circular shape, an irregular shape, etc., to be compatible with the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64. The second frame 62 can be made of aluminum material and can be flexibly set according to the actual situation, and is not limited to the embodiment described herein.

[0115] The second solar power generation layer 61 is located between the second top plate layer 63 and the second bottom plate layer 64. That is, the second top plate layer 63 is located above the second solar power generation layer 61, and the second bottom plate layer 64 is located below the second solar power generation layer 61, so as to wrap the second solar power generation layer 61 and achieve effective protection for the second solar power generation layer 61.

[0116] Thus, the second frame 62 tightly connects the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64 together to form a stable whole structure, which improves the structural stability and reliability of the hood 103. At the same time, it effectively ensures the stability and integrity of the second solar power generation layer 61, enabling it to work stably.

[0117] In this embodiment, the hood 103 can serve as a power generation component to provide power to the battery pack 101, and also as a protective component to protect the front of the vehicle 100.

[0118] In practical design, such as Figure 19 As shown, a second connector 82 can be installed on the hood 103. The second connector 82 is used to transmit current. The second connector 82 can be plugged into the socket of the charging controller 7, so that the electrical connection with the charging controller 7 can be realized through the second connector 82, thereby realizing the electrical connection between the second solar power generation layer 61 and the battery 4. Thus, the electrical energy generated by the second solar power generation layer 61 can flow into the charging controller 7 through the second connector 82. The charging controller 7 will monitor and adjust the current to ensure that the electrical energy is collected at an appropriate speed and voltage through the connecting copper busbar 85 to the distribution box, and then uniformly distributed by the distribution box.

[0119] In some embodiments, such as Figure 23 As shown, the second frame 62 forms an inwardly open second insertion slot 621. The height, i.e., the depth, of the second insertion slot 621 should match the thickness of the overall structure after the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64 are attached and connected. This allows the edges of the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64 to be inserted and fixed in the second insertion slot 621, making installation convenient. This achieves the fixation of the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64 on the second frame 62, thereby ensuring a stable connection between the second top plate layer 63, the second solar power generation layer 61, and the second bottom plate layer 64, preventing loosening or falling off. Together with the second frame 62, they form a stable and reliable structure, improving the structural strength of the hood 103 and helping to protect the front of the vehicle 100.

[0120] In some embodiments, the second top plate layer 63 is made of fiberglass.

[0121] Specifically, fiberglass has the characteristics of high strength, light weight, corrosion resistance, and wear resistance. By making the second roof layer 63 with fiberglass, the strength of the second roof layer 63 can be improved, the weight of the nacelle cover 103 can be reduced, and the corrosion of external chemicals can be effectively prevented, thereby effectively protecting the second solar power generation layer 61. At the same time, the fiberglass-made second roof layer 63 allows sunlight to pass through, thereby ensuring that the second solar power generation layer 61 can absorb sunlight.

[0122] In other embodiments, the second base plate layer 64 is made of high-strength steel.

[0123] Specifically, high-strength steel has extremely high strength and toughness. By using high-strength steel to manufacture the second base plate layer 64, the strength and durability of the second base plate layer 64 can be improved, enabling it to withstand greater impacts. This can effectively protect the second solar power generation layer 61 and prevent it from deforming or being damaged.

[0124] Therefore, the structural strength of the hood 103 can be effectively improved by using the second top plate layer 63 made of fiberglass and the second bottom plate layer 64 made of high-strength steel, which helps it resist external impact forces, thereby improving the driving safety of the vehicle 100 and the safety of the battery pack 101.

[0125] In actual design, for example, the thickness of the fiberglass can be set to 1mm, 2mm, 3mm or other, the thickness of the second solar power generation layer 61 can be set to 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or other, and the thickness of the high-strength steel can be set to 1mm, 2mm, 3mm or other. These can be flexibly set according to actual conditions and needs, and are not limited to those described in this embodiment.

[0126] In the actual installation process, the silicon wafer can be placed between the fiberglass and the high-strength steel, and then compacted by filling with EVA material. After that, it can be encapsulated with the second frame 62, that is, the fiberglass and the high-strength steel and the second solar power generation layer 61 made of silicon wafer and EVA material are inserted into the second insertion groove 621 of the second frame 62.

[0127] In other embodiments, such as Figure 6 As shown, the battery pack 101 is arranged in a Y-direction, that is, the battery pack 101 is arranged on the top of the vehicle 100 along the front-rear direction of the vehicle 100.

[0128] Therefore, the battery pack 101 can provide effective support for the vehicle 100, thereby improving the overall torsional stiffness of the vehicle 100, which in turn helps to improve the handling performance of the vehicle 100, reduce the deformation and vibration of the vehicle 100 during driving, and thus improve ride comfort and safety.

[0129] In other embodiments, the battery pack 101 of this invention uses a quadrupole cell, which has high performance and can effectively reduce the heat generation of the battery 4. At the same time, the quadrupole long blade cell can also enhance the overall rigidity of the frame 102.

[0130] In practical design, such as Figure 9 and Figure 11 As shown, the bottom of the battery cell can be bonded to the heat spreader 11 with thermally conductive adhesive, and the top of the battery cell can be bonded to the pull plate 84 with structural adhesive. The pull plate 84 is fixed to the expansion beam 111 with rivets, thereby improving the installation stability and reliability of the battery cell.

[0131] There is a certain space gap between the upper part of the battery cell and the upper protective plate 2. This space gap can serve as an air insulation layer, which can isolate the heat of solar energy from the battery pack 101, thereby preventing excessive solar heat from affecting the battery pack 101.
