Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to an engine hood; it also relates to a vehicle equipped with the engine hood. Background Technology

[0002] Currently, automobiles generally use non-renewable energy sources, such as gasoline, diesel, or natural gas, for power. Vehicle exhaust emissions are a major source of pollution, contributing to the greenhouse effect and exacerbating the urban heat island effect, thus impacting health. While electric vehicles are powered by electricity and do not emit harmful gases that pollute the atmosphere, their widespread use due to their environmental friendliness is a significant concern, as they require a large amount of electricity.

[0003] Furthermore, all electrical components in vehicles require power from onboard batteries. Electric vehicles need to have their batteries charged at dedicated charging stations, while gasoline or natural gas vehicles require an engine to drive a generator, which then charges the battery through a charging system. Therefore, existing vehicles still suffer from high energy consumption and poor environmental performance, hindering low-carbon development, environmental protection, and energy conservation. Utility Model Content

[0004] In view of this, the present invention aims to provide an engine hood to facilitate energy conservation and consumption reduction in vehicles.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An engine hood, comprising a hood body;

[0007] The hood body is provided with a cover facing the outside of the engine compartment. The cover has a photoelectric conversion layer capable of photoelectric conversion, and a cover layer located outside the photoelectric conversion layer.

[0008] The portion of the cover layer that covers at least the photoelectric conversion layer is made of a transparent material.

[0009] Furthermore, the machine cover body has an opening in the middle, and the cover covers the opening.

[0010] Furthermore, the hood body includes an outer hood panel and an inner hood panel that are fastened together, and the opening includes an outer opening and an inner opening arranged accordingly; the outer opening is disposed through the outer hood panel, the inner opening is disposed through the inner hood panel, and a cavity is formed between the outer hood panel, the inner hood panel, and the cover.

[0011] Furthermore, the edge of the inner opening is located inside the edge of the outer opening, and the inner side of the cover is connected to both the edge of the outer opening and the edge of the inner opening.

[0012] The cover is bonded to the edge of the outer opening and the edge of the inner opening with adhesive material, and a sealing material is provided between the cover and the edge of the outer opening and the edge of the inner opening.

[0013] Furthermore, the edge of the outer opening is provided with a recessed groove, and the adhesive material and the sealing material at the edge of the outer opening are located in the recessed groove. The edge of the inner opening is provided with a support portion for supporting the cover, and the adhesive material and the sealing material at the edge of the inner opening are located on the support portion. The sealing materials at the edges of the outer opening and the inner opening are both located outside the adhesive material at the corresponding positions.

[0014] Furthermore, the outer panel of the hood includes side portions disposed on the left and right sides, and an end portion connected between the rear ends of the side portions on both sides; the external opening is defined between the side portions on both sides and the end portion, and the front end of the external opening is blocked by the front end of the inner panel of the hood, and a portion of the cover covers the front end of the inner panel of the hood.

[0015] Furthermore, the inner panel of the hood is provided with an engine hood accessory mounting point; a gap is formed between the cover and the engine hood accessory mounting point, and the minimum value of the gap d satisfies: d > 60 mm.

[0016] Furthermore, the cover also includes a bottom layer located inside the photoelectric conversion layer, and the bottom layer, the photoelectric conversion layer and the cover layer are stacked together in sequence; both the cover layer and the bottom layer include a glass layer and a membrane layer stacked together, and the membrane layer in both the cover layer and the bottom layer is located on the side close to the photoelectric conversion layer.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The engine hood described in this utility model, by setting a photoelectric conversion layer on the hood body, enables the engine hood to convert light energy into electrical energy while ensuring the original use requirements of the engine hood. The electrical energy generated by the photoelectric conversion layer can be used to power the vehicle battery, which helps to improve the convenience of vehicle battery charging and reduce the consumption caused by vehicle battery charging. This is conducive to the low carbon emissions and energy consumption reduction of the vehicle. By setting a covering layer on the outside of the photoelectric conversion layer, the photoelectric conversion layer can be protected while meeting the photoelectric conversion requirements, thereby extending the service life of the covering.

[0019] Furthermore, placing the cover at the openings in the hood body, compared to installing covers on the entire hood, helps reduce production costs while ensuring functionality. The hood body uses an outer and inner panel that are interlocked, which enhances the overall structural strength of the hood body. The external and internal openings facilitate the placement of the cover, and the cavity between the outer and inner panels and the cover further enhances the overall structural strength of the engine hood by utilizing the high strength of the cavity structure. The cover is connected to the edges of both the external and internal openings, increasing the connection strength between the cover and the hood body and meeting the rigidity and modal requirements of the engine hood. The cover is connected to the edges of the external and internal openings using adhesive material, and a sealing material is placed at the connection point, with the sealing material located outside the adhesive material, forming a double-protection structure.

[0020] Secondly, the combination of the sink and the support structure further ensures the torsional stiffness and modal stability of the hood body and increases the stability of the cover installation, thereby improving the overall reliability of the engine hood assembly. This allows the sealing material to be located outside the adhesive material at the corresponding position, which helps prevent rainwater, dust, and other foreign objects from entering the engine compartment through the gaps between the cover and the opening edges. It also helps prevent the adhesive material from overflowing, improves the waterproof and dustproof rating of the engine compartment, and provides more reliable protection for the internal components, thus helping to avoid component damage and failure probability caused by foreign object intrusion.

[0021] Furthermore, the side and end sections of the outer hood panel improve material utilization, and the simple structure of the entire outer hood facilitates installation. The sealing of the external opening at the front of the inner hood panel ensures effective installation of the cover. This results in a gap greater than 60mm between the cover and the engine hood accessory mounting points, creating a buffer space. When a pedestrian collides with the engine hood, the cover has sufficient room to move towards the engine hood accessory mounting points, thus reducing injury. The layered structure of the cover—comprising the bottom layer, photoelectric conversion layer, and cover layer—works in tandem, enhancing stability. The overlapping of the glass and diaphragm layers strengthens the cover's resilience, making it less prone to deformation or damage under external forces.

[0022] Another objective of this utility model is to provide an engine hood, including an engine hood body and a cover provided on the engine hood body;

[0023] The hood body includes an outer hood panel and an inner hood panel that are fastened together, and at least one opening is provided on the outer hood panel;

[0024] The cover covers the opening and has a photoelectric conversion layer capable of photoelectric conversion, and a cover layer located outside the photoelectric conversion layer. At least the portion of the cover layer that covers the photoelectric conversion layer is made of a transparent material.

[0025] The engine hood described in this utility model has a photoelectric conversion layer on the cover, enabling the engine hood to convert light energy into electrical energy. Under sunlight, the photoelectric conversion layer can convert light energy into electrical energy and charge the vehicle battery, thereby improving the convenience of vehicle battery charging and reducing energy consumption caused by the vehicle battery, which has the advantages of energy saving and environmental protection. The hood body is formed by fastening an outer hood panel and an inner hood panel. An opening is provided on the outer hood panel and covered by the cover, which helps to enhance the overall protective performance of the hood body. The transparent part helps to ensure that light can reach the photoelectric conversion layer and maintain the photoelectric conversion efficiency.

[0026] Furthermore, the overall covering layer provides physical protection for the photoelectric conversion layer, preventing it from being corroded by dust and rainwater and avoiding mechanical scratches. This ensures the stable operation of the photoelectric conversion layer and guarantees the continuous effectiveness of the hood's photoelectric function. The covering layer covers the openings, and from the vehicle's appearance, the hood maintains a relatively flat and uniform visual effect. It cleverly integrates functionality and appearance design, satisfying the vehicle's needs for photoelectric conversion and other functions while maintaining the vehicle's original aesthetic appeal. This not only enhances the overall quality of the vehicle but also increases its market appeal.

[0027] In addition, this utility model also proposes a vehicle that has an engine hood as described above.

[0028] The vehicle described in this utility model, by setting the engine hood as described above, helps to reduce vehicle energy consumption and is conducive to energy conservation and environmental protection. Attached Figure Description

Furthermore, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Example 1

[0054] This embodiment relates to an engine hood that improves the energy efficiency and reduces consumption of a vehicle by optimizing its structure.

[0055] In terms of overall structure, the engine hood described in this embodiment includes a hood body 1, on which a cover 2 is provided facing outwards from the engine compartment. The cover 2 has a photoelectric conversion layer 201 capable of photoelectric conversion, and a cover layer 202 located outside the photoelectric conversion layer 201. At least the portion of the cover layer 202 covering the photoelectric conversion layer 201 is made of a transparent material.

[0056] At this point, as described above, by providing a photoelectric conversion layer 201 on the engine hood body 1, while ensuring the original function of the engine hood as an opening and closing component, the engine hood is equipped with the ability to convert light energy into electrical energy. Furthermore, the electrical energy generated by the photoelectric conversion layer 201 can be used to power the vehicle battery, improving the convenience of charging the vehicle battery and reducing energy consumption during charging. This achieves the effects of low-carbon environmental protection and reduced energy consumption in the vehicle. Of course, by providing a covering layer 202 on the outside of the photoelectric conversion layer 201, this embodiment not only meets the photoelectric conversion requirements of the photoelectric conversion layer 201 but also protects the photoelectric conversion layer 201, thereby extending the service life of the covering component 2.

[0057] Based on the above overview, an exemplary structure of the engine hood described in this embodiment is as follows: Figure 1 and Figure 2 As shown in the image.

[0058] In some embodiments, the hood body 1 has an opening 103 in the middle, and a cover 2 covers the opening 103. Placing the cover 2 at the opening 103 of the hood body 1 helps reduce production costs while ensuring the functionality of the engine hood. For vehicles, reducing weight helps reduce energy consumption, improve fuel economy, or increase the driving range of electric vehicles.

[0059] In some embodiments, such as Figures 3 to 5 As shown, the hood body 1 includes an outer hood panel 101 and an inner hood panel 102 that are fastened together. The openings 103 include an outer opening 1031 and an inner opening 1032. The outer opening 1031 penetrates the outer hood panel 101, and the inner opening 1032 penetrates the inner hood panel 102. A cavity Q is also formed between the outer hood panel 101, the inner hood panel 102, and the cover 2. The hood body 1, with its outer hood panel 101 and inner hood panel 102 fastened together, and the cavity Q formed between these components, enhances the overall structural strength of the hood. The outer opening 1031 and inner opening 1032 facilitate the arrangement of the cover 2. During design, the position and size of the outer opening 1031 and inner opening 1032 can be rationally planned to avoid excessively weakening the overall structural strength of the hood body 1.

[0060] like Figure 5 As shown in the diagram, in this embodiment, the edge of the inner opening 1032 is located inside the edge of the outer opening 1031, and the inner surface of the cover 2 is connected to both the edge of the outer opening 1031 and the edge of the inner opening 1032. The cover 2 is bonded to both the edge of the outer opening 1031 and the edge of the inner opening 1032 using adhesive material 3, and a sealing material 4 is provided between the cover 2 and both the edge of the outer opening 1031 and the edge of the inner opening 1032. This arrangement makes the area of ​​the outer opening 1031 larger than the area of ​​the inner opening 1032. Connecting the cover 2 to both the edge of the outer opening 1031 and the edge of the inner opening 1032 improves the ease of installation of the cover 2 on the hood body 1, increases the connection strength between the cover 2 and the hood body 1, and simultaneously meets the rigidity and modal requirements of the engine hood. Furthermore, by setting adhesive material 3 and sealing material 4, it is beneficial to form a double layer of protection, thereby further improving the installation effect of the cover 2 on the machine cover body 1.

[0061] In terms of specific structure, in order to improve the efficiency and amount of light energy converted into electrical energy by the photoelectric conversion layer 201 in the cover 2, the area of ​​the external opening 1031 in this embodiment should be as large as possible while meeting the strength requirements of the outer panel 101 of the cover.

[0062] In some embodiments, the edge of the outer opening 1031 is provided with a groove 1013, and the adhesive material 3 and sealing material 4 at the edge of the outer opening 1031 are located in the groove 1013. The edge of the inner opening 1032 is provided with a support portion 1024 for supporting the cover 2, and the adhesive material 3 and sealing material 4 at the edge of the inner opening 1032 are located on the support portion 1024. Here, by providing the groove 1013 and the support portion 1024, it is beneficial to improve the support effect on the cover 2 and to facilitate the arrangement of the adhesive material 3 and sealing material 4. This ensures that the sealing material 4 is located on the outside of the adhesive material 3 at the corresponding position, which helps to prevent rainwater, dust and other foreign objects from entering the engine compartment from the gap between the cover 2 and the edge of the opening 103. It also helps to prevent the adhesive material 3 from overflowing, improves the appearance of the engine cover, and helps to avoid component damage and failure probability caused by foreign object intrusion.

[0063] In this embodiment, the bottom of the settling tank 1013 is used to support the inner side of the cover 2 and to provide the adhesive material 3 and the sealing material 4. In some embodiments, such as Figure 3 and Figure 6 As shown, the adhesive material 3 in this embodiment includes an outer adhesive 301 for connecting the cover 2 to the edge of the outer opening 1031, and an inner adhesive 302 for connecting the cover 2 to the edge of the inner opening 1032. In specific implementation, the outer adhesive 301 is disposed between the inner side of the cover 2 and the bottom of the recess 1013, thereby bonding the inner side of the cover 2 and the bottom of the recess 1013 together, thus fixing the cover 2 to the outer panel 101 of the machine cover.

[0064] In this embodiment, the inner adhesive 302 is disposed between the inner side of the cover 2 and the support 1024, thereby bonding the inner side of the cover 2 to the support 1024 and fixing the cover 2 to the inner panel 102 of the hood. In this embodiment, the outer adhesive 301 and the inner adhesive 302 can be single-component polyurethane glass adhesive from the prior art, which has the advantages of easy placement and high bonding strength.

[0065] It should be noted that, in this embodiment, the inner side of the outer adhesive 301 refers to the side facing the inside of the outer opening 1031, and the outer side refers to the side facing the outside of the vehicle. The outer side of the inner adhesive 302 refers to the side facing the inside of the inner opening 1032, and the outer side refers to the side facing the edge of the outer opening 1031.

[0066] Still refer to Figure 3 and Figure 6As described above, the sealing material 4 in this embodiment includes an outer sealing strip 401 disposed on the bottom of the settling tank 1013 and located outside the outer adhesive 301, and an inner sealing strip 402 disposed on the support portion 1024 and located outside the inner adhesive 302.

[0067] Here, the outer sealing strip 401 is positioned outside the outer adhesive 301. This serves two purposes: firstly, it prevents the outer adhesive 301 from overflowing outwards and contaminating the edge of the outer opening 1031 at the junction with the cover 2, thus ensuring the refined appearance of the outer surface of the casing body 1. Secondly, the outer sealing strip 401 also prevents external impurities from entering the inner side of the casing body 1 through the junction of the outer edge of the cover 2 and the outer opening 1031, thereby preventing contamination.

[0068] In this embodiment, the inner sealing strip 402 is located outside the inner adhesive 302. On the one hand, it can prevent the inner adhesive 302 from overflowing outward and contaminating the edge of the inner opening 1032 and the junction with the cover 2, thereby helping to maintain the refined appearance of the inner surface of the cover body 1. On the other hand, the inner sealing strip 402 can also prevent external impurities from entering the cover body 1 through the junction of the cover 2 and the inner opening 1032 and causing contamination.

[0069] In some embodiments, the outer panel 101 of this embodiment includes side portions 1011 disposed on the left and right sides, and end portions 1012 connected between the rear ends of the side portions 1011. An external opening 1031 is defined between the side portions 1011 and the end portions 1012, and the front end of the external opening 1031 is blocked by the front end of the inner panel 102 of the hood. A portion of the cover 2 covers the front end of the inner panel 102 of the hood. This arrangement is beneficial for improving the utilization rate of product materials and increasing the area of ​​the cover 2. The structure of the entire outer panel 101 is simple and easy to arrange and implement. By blocking the external opening 1031 by the front end of the inner panel 102 of the hood, the installation effect of the cover 2 is ensured.

[0070] An exemplary structure of the outer hood panel 101 in this embodiment is as follows: Figure 7 As shown, due to the arrangement of the side portion 1011 and the end portion 1012, the outer panel 101 of the hood is generally n-shaped, and the bottom of the aforementioned sink 1013 also follows the n-shape of the outer panel 101. Due to the shape of the outer panel 101, the front end of the cover 2 is connected to the front end of the inner panel 102 of the hood via the external adhesive 301, and the external sealing strip 401 is still located outside the external adhesive 301.

[0071] To meet the appearance requirements of the hood body 1, in this embodiment, the middle of the end portion 1012 is arched towards the front of the vehicle, forming an arc shape. The two side portions 1011 are symmetrically arranged, and both can be designed to be arc-shaped or straight, depending on the design requirements. Furthermore, the distance between the two side portions 1011 gradually decreases along the direction towards the front of the vehicle. Additionally, the connection between the two side portions 1011 and the end portion 1012 is preferably made by laser welding, which helps reduce production costs, facilitates implementation, and provides high connection strength, thereby ensuring the performance of the hood outer panel 101.

[0072] An exemplary structure of the inner panel 102 of the hood in this embodiment is as follows: Figure 8 As shown, the inner panel 102 of the hood is arched away from the outer panel 101 of the hood, which also helps to improve the structural strength of the hood body 1. To facilitate the connection between the cover 2 and the edge of the inner opening 1032, a protruding portion 1023 arching from the outer panel 101 is provided in the middle of the inner panel 102 of the hood. The inner opening 1032 is specifically located at the top of the protruding portion 1023, and the aforementioned support portion 1024 is also located at the top of the protruding portion 1023.

[0073] The protruding portion 1023 helps to reduce the height difference between the edge of the inner opening 1032 and the edge of the outer opening 1031, allowing the support portion 1024 to be bonded to the cover 2. Furthermore, the protruding portion 1023 further strengthens the structural strength of the inner panel 102 of the hood, and its simple structure facilitates its implementation. It should be noted that a solution where only the outer panel 101 of the hood has the outer opening 1031, and the cover 2 is bonded to the edge of the outer opening 1031, is also feasible.

[0074] In some embodiments, the cover 2 in this embodiment further includes a bottom layer 203 located inside the photoelectric conversion layer 201. The bottom layer 203, the photoelectric conversion layer 201, and the cover layer 202 are stacked together in sequence. Both the cover layer 202 and the bottom layer 203 include a glass layer 2021 and a membrane layer 2022 stacked together, and the membrane layer 2022 in both the cover layer 202 and the bottom layer 203 is located on the side closer to the photoelectric conversion layer 201. Here, the bottom layer 203, the photoelectric conversion layer 201, and the cover layer 202 in the cover 2 are stacked in sequence. This multi-layer structure works together to give the cover 2 better stability, while the stacking of the glass layer 2021 and the membrane layer 2022 helps to enhance the strength and toughness of the cover 2, making it less prone to deformation or damage when subjected to external forces.

[0075] An exemplary structure of the cover 2 described in this embodiment is as follows: Figure 9As shown, the glass layer 2021 is primarily made of silicon dioxide, which has high transparency, allowing light to pass through effectively and illuminating the photoelectric conversion layer 201, thereby improving the energy conversion efficiency. Silicon dioxide glass has strong corrosion resistance and does not readily react with most chemicals, ensuring the stability of the cover 2 in various environments and extending its service life. Furthermore, silicon dioxide glass has high hardness and mechanical strength, giving the cover 2 a certain degree of wear resistance and pressure resistance, making it less prone to scratches and damage.

[0076] In this embodiment, the diaphragm layer 2022 is preferably made of PVB (Polyvinyl Butyral). This not only gives the cover 2 good sound insulation and transparency, but also utilizes the high tensile strength and impact resistance of PVB to improve the cover 2's ability to withstand external forces and prevent breakage, thereby enhancing the safety of the housing body 1. The diaphragm layer 2022 in this embodiment also facilitates the fixation of the photoelectric conversion layer 201 between the cover layer 202 and the bottom layer 203. The photoelectric conversion layer 201 is preferably made of a solar panel, which is easy to install on the housing body 1 and has good photoelectric conversion efficiency. The diaphragm layer 2022 is bonded to both the glass layer 2021 and the photoelectric conversion layer 201, thus giving the cover 2 a sandwich structure with high strength and reliability.

[0077] In some embodiments, the thickness of the glass layer 2021 is preferably 1.8-2.2 mm, the thickness of the glass layer 2021 is preferably 0.55-0.8 mm, and the thickness of the solar panel is preferably 90-150 μm. The thickness ranges of the glass layer 2021, the glass layer 2021, and the solar panel in this embodiment are designed to meet the usage requirements of the housing body 1, providing high structural strength and thus extending the service life of the housing body 1. Furthermore, this also helps ensure the conversion efficiency and amount of light energy by the photoelectric conversion layer 201 in the covering 2.

[0078] In some embodiments, the thickness of the glass layer 2021 may be, for example, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, or 2.2 mm. The thickness of the separator layer 2022 may be, for example, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.76 mm, or 0.8 mm. The thickness of the solar panel sheet may be, for example, 90 μm, 95 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, or 150 μm.

[0079] In this embodiment, the photoelectric conversion layer 201 is connected to a solar controller installed inside the vehicle via a wiring harness. The electrical energy acquired by the photoelectric conversion layer 201 is converted into DC power. The current is then boosted by the solar controller and inverted into 220V AC power. This AC power is then converted back to DC power by the on-board charger (OBC), and further boosted by a DC-DC converter (DC-DC converter) controller before being connected to the power battery via the wiring harness. Alternatively, the DC power can be stepped down by the DC-DC controller and then connected to the vehicle battery via the wiring harness. The solar controller can be installed in the engine compartment or other mounting spaces at the front of the vehicle. The specific wiring harness connections between the components can be determined based on the vehicle's structure. If necessary, avoidance structures to accommodate the wiring harnesses may be installed on surrounding components.

[0080] In some embodiments, the inner panel 102 of the hood is provided with an engine hood accessory mounting point, and a gap is formed between the cover 2 and the engine hood accessory mounting point, wherein the minimum value of the gap d satisfies: d > 60 mm. The setting of this gap d range is conducive to forming a buffer space, so that when a pedestrian collides with the engine hood, the cover 2 has enough space to move towards the engine hood accessory mounting point, thereby helping to reduce injury to the pedestrian.

[0081] The engine hood accessories include two engine hood latches 6 located at the front end of the inner hood panel 102, with the specific mounting points being engine hood latch mounting points 1022 on the inner hood panel 102. The engine hood accessories also include two engine hood hinges 5 located at the rear end of the inner hood panel 102, with the specific mounting points being engine hood hinge mounting points 1021 on the inner hood panel 102. In practice, both the engine hood latch mounting points 1022 and the engine hood hinge mounting points 1021 can be installed using mounting holes.

[0082] In terms of detailed structure, for ease of distinction, such as Figures 11 to 13 As shown, the minimum gap between the hood latch mounting point 1022 and the cover 2 in the vehicle height direction is called the first gap d1, and the minimum gap between the hood hinge mounting point 1021 and the cover 2 in the vehicle height direction is called the second gap d2. In specific implementations, the first gap d1 can be, for example, 60.5mm, 61mm, 62mm, 63mm, 64mm, or 65mm, and the second gap d2 can be, for example, 60.5mm, 61mm, 62mm, 63mm, 64mm, or 65mm. Of course, in specific implementations, the specific values ​​of the first gap d1 and the second gap d2 can be adaptively adjusted according to usage requirements.

[0083] Based on the above introduction, as a preferred embodiment of the engine hood in this example, specifically, it is still combined with... Figures 1 to 13 As shown, the engine hood includes a hood body 1 and a cover 2 disposed on the hood body 1. The hood body 1 includes an outer hood panel 101 and an inner hood panel 102 that are fastened together, and at least an opening 103 is provided on the outer hood panel 101.

[0084] The cover 2 covers the opening 103 and has a photoelectric conversion layer 201 capable of photoelectric conversion, and a cover layer 202 located outside the photoelectric conversion layer 201. At least the portion of the cover layer 202 covering the photoelectric conversion layer 201 is made of a transparent material.

[0085] Specifically, such as Figure 5 As shown, a cavity Q is formed between the outer hood panel 101, the inner hood panel 102, and the cover 2 in the snap-fit ​​state, which helps to improve the overall strength of the engine hood. The opening 103 includes an outer opening 1031 that passes through the outer hood panel 101 and an inner opening 1032 that passes through the inner hood panel 102. The edge of the inner opening 1032 is located inside the edge of the outer opening 1031, and the inner side of the cover 2 is connected to the edges of the outer opening 1031 and the inner opening 1032, respectively.

[0086] In this embodiment, the cover 2 is bonded to the edge of the outer opening 1031 and the edge of the inner opening 1032 by adhesive material 3, and sealing material 4 is provided between the cover 2 and the edge of the outer opening 1031 and the edge of the inner opening 1032.

[0087] Furthermore, the edge of the external opening 1031 is provided with a recess 1013, and the adhesive material 3 and sealing material 4 at the edge of the external opening 1031 are located in the recess 1013. The edge of the internal opening 1032 is provided with a support portion 1024 for supporting the cover 2, and the adhesive material 3 and sealing material 4 at the edge of the internal opening 1032 are located on the support portion 1024. The sealing material 4 at the edges of both the external opening 1031 and the internal opening 1032 is located outside the corresponding adhesive material 3.

[0088] The adhesive material 3 includes an outer adhesive 301 disposed between the cover 2 and the bottom of the sink 1013, and an inner adhesive 302 disposed between the cover 2 and the bottom of the support 1024. This provides the advantages of easy installation and good connection effect.

[0089] Furthermore, the sealing material 4 includes an outer sealing strip 401 disposed on the outside of the outer adhesive 301 and an inner sealing strip 402 disposed on the outside of the inner adhesive 302. The outer sealing strip 401 and the inner sealing strip 402 help prevent adhesive overflow and contamination of the housing body 1, thus ensuring the refined appearance of the housing body 1. Simultaneously, they also improve the sealing effect between the cover 2 and the outer and inner panels of the housing, preventing external impurities from entering the cavity Q through the connection between the cover 2 and the housing body 1.

[0090] like Figure 7 As shown, the outer panel 101 of the machine cover includes side portions 1011 disposed on the left and right sides, and end portions 1012 connected between the rear ends of the side portions 1011. An external opening 1031 is defined between the side portions 1011 and the end portions 1012, and the front end of the external opening 1031 is blocked by the front end of the inner panel 102 of the machine cover. A portion of the cover member 2 covers the front end of the inner panel 102 of the machine cover. In this embodiment, the structure of the outer panel 101 is arranged such that the outer panel 101 is generally "n"-shaped. This arrangement helps to improve the utilization rate of product materials, and the overall structure of the outer panel 101 is simple and easy to implement.

[0091] In this embodiment, the cover 2 further includes a bottom layer 203 located inside the photoelectric conversion layer 201. The bottom layer 203, the photoelectric conversion layer 201, and the cover layer 202 are stacked together in sequence. Both the cover layer 202 and the bottom layer 203 include a glass layer 2021 and a membrane layer 2022 stacked together, and the membrane layer 2022 in both the cover layer 202 and the bottom layer 203 is located on the side closer to the photoelectric conversion layer 201. The cover 2 in this embodiment has high structural stability, facilitates the placement of the photoelectric conversion layer 201 in the cover 2, and helps ensure the photoelectric conversion efficiency of the photoelectric conversion layer 201.

[0092] The thickness of the glass layer 2021 is preferably 1.8-2.2 mm, and the thickness of the solar panel is preferably 0.55-0.8 mm. This allows the cover body 1 to function as both an opening / closing element and a photoelectric conversion element, while still meeting the strength requirements of the cover 2.

[0093] Furthermore, the inner panel 102 of the hood is provided with engine hood accessory mounting points, and a gap is formed between the cover 2 and the engine hood accessory mounting points, and the minimum value of the gap d satisfies: d > 60mm. Specifically, the engine hood accessory mounting points are engine hood latch mounting points 1022 and engine hood hinge mounting points 1021 provided on the inner panel 102 of the hood.

[0094] By setting the minimum clearance range d here, a safe buffer space can be formed at the front of the vehicle body. In the event of a collision between a person and a vehicle, the cover 2 has enough space to move towards the engine hood accessory mounting point, thereby reducing the injury to pedestrians and improving the vehicle's pedestrian protection effect.

[0095] In this embodiment, the engine hood has an external opening 1031 and an internal opening 1032 on the outer panel 101, which are covered by a cover 2. This enhances the overall protective performance of the engine hood body 1. The transparent portion of the cover 2 ensures that light can reach the photoelectric conversion layer 201, thereby ensuring photoelectric conversion efficiency. Simultaneously, the cover layer 202 and the bottom layer 203 work together from the inside and outside to provide physical protection for the photoelectric conversion layer 201, ensuring its stable operation and thus guaranteeing the continuous effectiveness of the engine hood's photoelectric function.

[0096] Furthermore, by covering the outer opening 1031 and the inner opening 1032 with the cover 2, the engine hood maintains a relatively flat and uniform visual effect from the perspective of the vehicle's appearance. This cleverly integrates functionality with appearance design, satisfying the vehicle's needs for photoelectric conversion and other functions while maintaining the vehicle's original aesthetic appeal. This not only helps to improve the overall quality of the vehicle but also enhances its attractiveness in the market.
