Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a pickup truck cargo box roll-up device. Background Technology

[0002] A pickup truck bed roll-up cover is a device used to cover and protect the cargo bed of a pickup truck. It typically consists of a roll-up cover, a roll-up box, and guide frames. The roll-up cover is driven by an electric drive system to extend or retract within the frames. In existing pickup truck bed roll-up covers, both the electric drive system and the lighting rely on the vehicle's power supply. Prolonged use can easily lead to power depletion in the vehicle, affecting its normal starting.

[0003] A Chinese patent with publication number CN223224179U discloses a pickup truck tailgate roller shutter cover, including a curtain, a roller shutter box, a guide rail, and a solar power generation system. A photovoltaic panel is suspended above the curtain and connected to the front end of the guide rail. A solar controller controls the photovoltaic panel to charge a battery, which in turn powers the motor. However, in this design, the photovoltaic panel is suspended above the curtain and fixed at a specific position at the front end of the guide rail, preventing it from moving with the roller shutter slats and limiting the power generation area. Furthermore, the photovoltaic panel is separate from the roller shutter slats, lacking an integrated structural connection, resulting in insufficient installation stability and waterproof sealing. Suspending the photovoltaic panel above the curtain also increases the overall height, affecting the appearance.

[0004] Another Chinese patent, with publication number CN222321180U, discloses a solar power supply system for a pickup truck roll-up cover. The solar panel is placed at the front of the vehicle body and is not integrated with the roll-up cover. The power generation area is small and requires additional installation space.

[0005] Furthermore, the existing technology lacks effective protection for the cable connection between the photovoltaic panel and the shutter blades. During the shutter rewinding process, the cable can easily enter the gap between two adjacent shutter blades, causing pressure damage and affecting the reliability and service life of the circuit connection.

[0006] The installation of existing roller shutter devices usually requires drilling holes in the side skirts of pickup truck beds for fixing. This is not only cumbersome, but drilling can also damage the vehicle's structure, affecting its appearance and sealing. Furthermore, it is difficult to adapt to the dimensional tolerances of different vehicle models' cargo boxes. Summary of the Invention

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a pickup truck cargo box roll-up device.

[0008] This invention is achieved using the following technical solution:

[0009] A pickup truck bed roll-up shutter device includes a roll-up shutter cover, a roll-up shutter box for housing the roll-up shutter cover, and a frame for guiding the roll-up shutter cover to unfold and retract. The roll-up shutter cover is composed of multiple roll-up shutter slats connected in sequence. The upper surface of the roll-up shutter slats is provided with a groove, in which a solar photovoltaic panel is fixedly installed, and the gap between the photovoltaic panel and the groove is filled with a sealing material. It also includes an energy storage device, in which the solar photovoltaic panels are connected in series and / or in parallel by flexible cables, and the total output line after the electrical connection is connected to the input end of the energy storage device. The energy storage device is provided with at least one external discharge port and at least one external charging port.

[0010] By fixing the solar photovoltaic panel into the groove on the upper surface of the roller blind slats, the structure of the photovoltaic panel and the roller blind slats is integrated, making full use of the surface space of the roller blind slats for solar power generation. The groove provides an embedded installation position for the photovoltaic panel, making the photovoltaic panel basically flush with the top surface of the roller blind slats, improving the degree of structural integration and installation stability. The sealing material fills the gap between the photovoltaic panel and the groove, ensuring the fixed connection of the photovoltaic panel and achieving waterproof sealing, preventing moisture infiltration from affecting the service life. The flexible cable adopts a series and / or parallel connection method, which can adjust the output voltage and current according to actual needs, and the connection method is flexible and reliable. The energy storage device stores the electrical energy generated by the solar photovoltaic panel and supplies power to the lighting inside the roller blind cover, the winding motor in the roller blind box, and external mobile devices through the external discharge port. It can also receive mains power or vehicle power through the external charging port, realizing independent power supply and reducing the risk of vehicle power failure.

[0011] Preferably, limiting spaces are provided on both sides of the roller blind slats; one end of a hinge body is limited within the limiting space, and the other end of the hinge body is limited within the limiting space of the adjacent roller blind slats, and the adjacent roller blind slats are hinged together through the hinge body.

[0012] Preferably, at least one end of the solar photovoltaic panel protrudes from the edge of the roller blind, and cables extend downward from both sides of the bottom of the protruding part, which are respectively connected to the adjacent solar photovoltaic panels; the bottom of the roller blind is an arc-shaped structure for easy rolling, and a first end cap is fixed to the side of the roller blind. An anti-pressure block is provided on each side of the first end cap. The anti-pressure block is used to limit the cable to prevent the cable from entering the gap between two adjacent roller blinds and causing pressure damage.

[0013] Preferably, a limiting block is provided on the inner side of the first end cap, and the limiting block cooperates with the anti-pressure block to limit the direction of the cable.

[0014] Preferably, it further includes a second end cap, which is fixedly assembled on the first end cap. The upper end of the second end cap is provided with a cover plate, which covers the protruding part of the solar photovoltaic panel and provides physical protection for the protruding part. Furthermore, the second end cap, together with the first end cap, confines the cable between the two and protects the cable.

[0015] Preferably, the frame is a pair, with a guide rail at the bottom of at least one frame and at least one set of fasteners along the guide rail direction for detachably fixing the frame to the inner side skirt of the pickup truck bed.

[0016] Preferably, the fastener includes an upper mounting arm and a lower clamping claw; the upper mounting arm has an elongated waist-shaped hole and is locked to the guide rail by a locking nut; the lower clamping claw has a U-shaped clamping groove with anti-slip serrations, and the U-shaped clamping groove clamps onto the inner side skirt of the pickup truck bed from bottom to top. When the locking nut is tightened, it drives the clamping claw to tighten and the serrations to bite into the skirt, so as to fix the frame of the pickup truck without drilling.

[0017] Preferably, the elongated waist-shaped hole is arranged along the length of the upper mounting arm, and the installation position of the roller shutter cover relative to the cargo box skirt is adjustable by means of the waist-shaped hole, so as to adapt to the cargo box size tolerance of different vehicle models.

[0018] Preferably, multiple sets of fasteners are arranged at intervals along the length of the frame to distribute the weight of the roller shutter assembly with embedded photovoltaic panels at multiple points.

[0019] Preferably, the roller shutter cover also includes a front cover plate located at the front, and a solar photovoltaic panel is also fixedly installed on the upper surface of the front cover plate.

[0020] Preferably, a cleaning brush is provided on the front cover plate of the roller shutter, and the cleaning brush is located at the entrance of the roller shutter box for retracting the roller shutter cover.

[0021] Preferably, the external discharge port is used to supply power to the lighting inside the roller shutter cover, the winding motor inside the roller shutter box, and external mobile equipment.

[0022] Preferably, it further includes a power connector, a tailgate leaf connected to the tail end of the roller shutter cover, and a frame for guiding the roller shutter cover to unfold and retract. The power connector is disposed between the main output line and the energy storage device; the first end of the power connector is disposed on the tailgate leaf, and the second end of the power connector is disposed on the frame.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By fixing the solar photovoltaic panel in the groove on the upper surface of the roller blind, the structure of the photovoltaic panel and the roller blind is integrated, making full use of the surface space of the roller blind for solar power generation. Compared with the existing technology where the photovoltaic panel is suspended above the curtain or placed at the front of the carriage, the photovoltaic panel of the present invention can move with the roller blind, generating a larger area, and does not affect the rolling function of the roller blind. The groove embedded installation makes the photovoltaic panel basically flush with the top surface of the roller blind, with a high degree of structural integration and a neat and beautiful appearance.

[0024] (2) By filling the gap between the photovoltaic panel and the groove with sealing material, the photovoltaic panel is firmly fixed and waterproofed, overcoming the defects of the existing technology, such as lack of structural integration between the photovoltaic panel and the roller shutter, insufficient installation stability and waterproof sealing. The flexible cable adopts a series and / or parallel connection method, which is flexible and reliable. The output voltage and current can be adjusted according to actual needs.

[0025] (3) By setting the first end cover, anti-pressure block, limit block, second end cover and cover plate, a complete cable protection system is formed, which effectively prevents the cable from entering the gap between adjacent roller shutters during the winding process, thus preventing pressure damage, ensuring the reliability and service life of the circuit connection, and overcoming the defect of lack of effective protection for cable connection in the prior art.

[0026] (4) By using a mounting arm with an upper end and a clamping claw with a U-shaped clamping groove with anti-slip serrations, a hole-free fixing is achieved, which avoids damage to the vehicle body structure and makes the installation simple and quick. The waist-shaped hole provides adjustment space for the installation position, which allows the roller shutter device to adapt to the cargo box size tolerance of different vehicle models, improves the versatility and adaptability of the product, and overcomes the defects of existing technologies that require hole fixing and are difficult to adapt to different vehicle models.

[0027] (5) By configuring an energy storage device and setting an external discharge port and an external charging port, an independent power supply is provided for the electric drive system and lighting of the roller shutter cover, so that it no longer depends on the power supply of the car power supply. This effectively avoids the problem of the car power supply being depleted due to the long-term use of the roller shutter cover and ensures the normal start of the vehicle. At the same time, the energy storage device can also charge outdoor mobile devices, expand the functional application range of the roller shutter device and improve the convenience of use.

[0028] (6) By installing a cleaning brush on the front cover of the roller blind, the surface of the roller blind is cleaned when the roller blind is rolled up, keeping the roller blind and photovoltaic panel surface clean, maintaining the power generation efficiency of the photovoltaic panel and the overall performance of the roller blind device, and extending its service life.

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0035] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a pickup truck bed roll-up device, including a roll-up cover 10, a roll-up box 20 for accommodating the roll-up cover 10, and a frame 30 for guiding the roll-up cover 10 to unfold and retract.

[0036] like Figure 4 As shown, the roller blind cover 10 is composed of multiple roller blind slats 11 connected in sequence. The upper surface of each roller blind slat 11 has a groove 111, the width of which is approximately equal to the width of the solar photovoltaic panel 12. The depth of the groove 111 is slightly less than the thickness of the solar photovoltaic panel 12, so that after the solar photovoltaic panel 12 is embedded in the groove 111, its top surface is approximately flush with or slightly higher than the top surface of the roller blind slat 11.

[0037] The solar photovoltaic panel 12 is fixedly installed in the groove 111, and the gap between the photovoltaic panel 12 and the groove 111 is filled with sealant. The sealant is a sealant, which is injected along the gap between the solar photovoltaic panel 12 and the groove 111 to fill the gap between them. After curing, the sealant forms an elastic sealing layer, which firmly fixes the solar photovoltaic panel 12 in the groove 111 and prevents the solar photovoltaic panel 12 from loosening or falling off during the unfolding and rewinding of the shutter 11.

[0038] On the other hand, the sealant fills the gaps to form a waterproof seal, preventing rainwater or other liquids from seeping in from the gap between the solar photovoltaic panel 12 and the groove 111, avoiding moisture erosion of the internal structure of the roller shutter 11, and extending the service life of the roller shutter 11 and the solar photovoltaic panel 12.

[0039] like Figure 4 As shown, limiting spaces 112 are provided on both sides of the roller blind slat 11. One end of a hinge body 17 is limited within the limiting space 112, and the other end of the hinge body 17 is limited within the limiting space 112 of the adjacent roller blind slat 11. The adjacent roller blind slats 11 are hinged together by the hinge body 17.

[0040] The two ends of the hinge body 17 are respectively inserted into the limiting space 112 of the two adjacent roller blind slats 11. By limiting the hinge body 17 through the limiting space 112, the reliable connection and hinge function between the adjacent roller blind slats 11 are realized, ensuring the smooth movement of the roller blind slats 11 during the unfolding and rewinding process.

[0041] The bottom of the roller blind slat 11 has an arc-shaped structure for coordinated winding. The arc-shaped structure allows multiple roller blind slats 11 to be rolled into the roller blind box 20 in sequence during winding, forming a compact roll and saving space.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention also includes an energy storage device 40, which is a battery or a lithium battery pack, and is fixedly installed below the roller shutter box 20 or assembled at the bottom of the cargo box.

[0043] like Figure 8 As shown, at least one end of the solar photovoltaic panel 12 protrudes from the end edge of the roller shutter 11, forming a protruding portion 121.

[0044] like Figure 6 As shown, the flexible cable 13 includes a positive cable 131 and a negative cable 132. Positive cables 131 extend downwards from both sides of the bottom of the protruding portion 121, and are connected to adjacent solar photovoltaic panels 12, thus achieving series connection of multiple solar photovoltaic panels 12. After all photovoltaic panels 12 are connected in series, the negative cable 132 extends from the last photovoltaic panel 12.

[0045] The negative cable 132 and the positive cable 131 at the beginning are connected to the electrical connection interface, and the main output line 14 is led out from the electrical connection interface and connected to the input end of the energy storage device 40.

[0046] When connected in series, the output voltages of each solar photovoltaic panel 12 are added together, and the total output voltage equals the sum of the output voltages of each solar photovoltaic panel 12. This method is suitable for applications requiring higher voltage. When connected in parallel, the positive terminals of each solar photovoltaic panel 12 are connected together via positive cable 131, and the negative terminals of each solar photovoltaic panel 12 are connected together via negative cable 132, forming a parallel circuit. In the parallel connection method, the output currents of each solar photovoltaic panel 12 are added together, and the total output current equals the sum of the output currents of each solar photovoltaic panel 12. This method is suitable for applications requiring larger current.

[0047] The energy storage device 40 is equipped with at least one external discharge port and at least one external charging port. The external discharge port is used to power the lighting inside the roller shutter cover 10, the winding motor inside the roller shutter box 20, and external mobile devices. The external charging port is used to receive power from the mains or vehicle power supply for charging.

[0048] The energy storage device 40 stores the electrical energy generated by the solar photovoltaic panel 12 and provides a stable power supply to subsequent electrical equipment through an external discharge port, avoiding power instability caused by changes in sunlight conditions. When the energy storage device 40 is low on power, it can be charged by connecting to mains power or a vehicle power source through an external charging port.

[0049] like Figure 4 , Figure 6 and Figure 8 As shown, a first end cap 15 is also fixed to the side of the roller shutter slat 11. The roller shutter slat 11 is provided with a first mounting hole 114, and the first end cap 15 is provided with a second mounting hole 153 that matches the first mounting hole 114. Screws pass through the second mounting hole 153 and the first mounting hole 114 to fix the first end cap 15 onto the roller shutter slat 11.

[0050] refer to Figure 8 and Figure 9 The bottom of the first end cover 15 has an arc-shaped base plate 155, which is adapted to the arc-shaped structure of the roller shutter leaf 11. The arc-shaped base plate 155 abuts against the arc-shaped structure of the roller shutter leaf 11 from bottom to top. Through the cooperation of the arc-shaped base plate 155 and the mounting hole, the first end cover 15 and the roller shutter leaf 11 are stably fixed.

[0051] refer to Figure 9Each side of the first end cap 15 is provided with an anti-pressure block 151. The anti-pressure block 151 is used to limit the cable 13 to prevent the cable 13 from entering the gap between two adjacent roller shutter slats 11 and causing damage. Specifically, the anti-pressure block 151 is a raised structure located on both sides of the roller shutter slats 11, forming a physical barrier between two adjacent roller shutter slats 11 to prevent the cable 13 from entering the gap between adjacent roller shutter slats 11.

[0052] When the roller shutter 11 is rolled up, the distance between adjacent roller shutter 11 decreases, and the anti-pressure block 151 provides limit protection for the cable 13 to prevent the cable 13 from being pinched and damaged by the adjacent roller shutter 11.

[0053] refer to Figure 9 A limiting block 152 is provided on the inner side of the first end cover 15. The limiting block 152 cooperates with the anti-pressure block 151 to limit the direction of the cable 13. The limiting block 152 has a protruding or groove structure, which cooperates with the anti-pressure block 151 to form a channel for the cable 13, regulate the laying path of the cable 13, and prevent the cable 13 from getting tangled or loose during the movement of the shutter blade 11.

[0054] like Figure 8 , Figure 9 and Figure 10 As shown, the present invention also includes a second end cap 16. The second end cap 16 is fixedly mounted on the first end cap 15. The first end cap 15 is provided with a pair of third mounting holes 154, and the second end cap 16 is provided with a pair of fourth mounting holes 162 that match the third mounting holes 154. Locking screws pass through the fourth mounting holes 162 and the third mounting holes 154 to fix the second end cap 16 on the first end cap 15.

[0055] refer to Figure 8 and Figure 10 The upper end of the second end cap 16 is provided with a cover plate 161. The cover plate 161 covers the protruding part 121 of the solar photovoltaic panel 12, providing physical protection for the protruding part 121 and preventing external impact or foreign objects from damaging the protruding part 121 of the photovoltaic panel 12.

[0056] The second end cap 16, together with the first end cap 15, confines the cable 13 between them, thus protecting the cable 13. A space is formed between the second end cap 16 and the first end cap 15 to accommodate the cable 13, and the cable 13 is confined and protected between them, forming a complete cable protection system.

[0057] When the pickup truck is parked in a sunny environment, the solar photovoltaic panel 12 receives sunlight and performs photoelectric conversion, transforming solar energy into electrical energy. Since the solar photovoltaic panel 12 is fixedly installed in the groove 111 on the upper surface of the shutter 11, the solar photovoltaic panel 12 is always in a state of receiving sunlight throughout the entire process of the shutter 11 being opened, and can continuously generate solar power.

[0058] The electrical energy generated by the solar photovoltaic panel 12 is transmitted to the energy storage device 40 via the flexible cable 13, where it is stored. When the electric drive system of the roller shutter cover 10 or the lighting is needed, the energy storage device 40 supplies power through the external discharge port, eliminating reliance on the vehicle's power supply and effectively avoiding the problem of power outages.

[0059] When the roller blind 11 needs to be rolled up, since the solar photovoltaic panel 12 and the roller blind 11 form an integrated structure and the roller blind 11 are connected by hinge body 17, multiple roller blind 11 together with the solar photovoltaic panel 12 on them can be rolled into the roller blind box 20 in sequence without affecting the rolling function of the roller blind cover 10.

[0060] During the winding process, the anti-pressure block 151 and the limiting block 152 limit the cable 13 to prevent it from being damaged by the adjacent roller shutter leaf 11. The second end cover 16 and its cover plate 161 provide physical protection for the protruding part 121 of the photovoltaic panel 12 and the cable 13, ensuring the reliability and service life of the circuit connection.

[0061] Example 2 like Figure 12 and Figure 13 As shown, based on Embodiment 1, this embodiment further defines the frame (30) as a pair, which are respectively set on both sides of the roller shutter cover (10). At least one frame (30) has a guide rail (31) at its bottom, and at least one set of fasteners (50) is provided along the direction of the guide rail (31) to detachably fix the frame (30) to the inner side skirt of the pickup truck box.

[0062] like Figure 13 As shown, the fastener (50) includes an upper mounting arm (51) and a lower clamping claw (52). The upper mounting arm (51) has an elongated waist-shaped hole (511) and is locked to the guide rail (31) by a locking nut. The elongated waist-shaped hole (511) is arranged along the length of the upper mounting arm (51), and the waist-shaped hole (511) allows the front and rear mounting positions of the roller shutter cover (10) relative to the cargo box skirt to be adjustable, adapting to the cargo box size tolerances of different vehicle models.

[0063] The lower clamping claw (52) is provided with a U-shaped clamping groove (521) with anti-slip serrations (522). The U-shaped clamping groove (521) clamps onto the inner side skirt of the pickup truck bed from bottom to top. The locking screw passes through the mounting hole 523 of the lower clamping claw (52). Then, the locking nut on the locking screw is screwed to drive the clamping claw (52) to tighten and the serrations (522) to bite the skirt to realize the pickup truck's hole-free fixed frame (30).

[0064] The specific installation process is as follows: The upper mounting arm (51) of the fastener (50) is fitted with the guide rail (31) through the elongated waist-shaped hole (511), and the position of the fastener (50) on the guide rail (31) is adjusted so that it corresponds to the inner side skirt of the pickup truck box. The U-shaped clamping groove (521) of the lower clamping claw (52) is clamped from bottom to top onto the inner side skirt of the pickup truck box.

[0065] Tighten the locking nut. When the locking nut is tightened, it drives the clamping claw (52) to tighten. The anti-slip serrations (522) in the U-shaped clamping groove (521) bite the skirt, realizing the firm fixation of the frame (30) and the cargo box skirt. Since the clamping claw (52) is used to clamp the skirt, there is no need to drill holes in the cargo box skirt, avoiding damage to the vehicle body structure, and the installation is simple and quick.

[0066] The waist-shaped holes provide adjustment space for the installation position, allowing the roller shutter device to adapt to the cargo box size tolerances of different vehicle models, thus improving the product's versatility and adaptability.

[0067] Multiple sets of fasteners 50 are arranged at intervals along the length of the frame 30, distributing the weight of the roller shutter cover 10 assembly with embedded photovoltaic panels 12 at multiple points. The multiple sets of fasteners 50 provide multi-point fixation, distributing the weight of the roller shutter cover 10 assembly and ensuring the stability and load-bearing capacity of the installation.

[0068] Example 3 like Figure 1 , Figure 2 and Figure 11 As shown, this embodiment, based on Embodiment 1 or Embodiment 2, further specifies that the roller blind cover 10 also includes a front cover plate 60 located at the front. The front cover plate 60 is a fixed part of the roller blind cover 10 and is located at the front end of the roller blind slats 11 after they are unfolded.

[0069] A solar photovoltaic panel 12 is also fixedly installed on the upper surface of the front cover plate 60 of the roller shutter. The width of the solar photovoltaic panel 12 is basically equal to the width of the front cover plate 60 of the roller shutter, and the length is basically equal to the length of the front cover plate 60 of the roller shutter, so that the solar photovoltaic panel 12 can completely cover the upper surface of the front cover plate 60 of the roller shutter.

[0070] The upper surface of the front cover plate 60 is also provided with a groove, and the solar photovoltaic panel 12 is embedded in the groove on the upper surface of the roller shutter front cover plate 60, forming a tight fit between the two. The gap between the photovoltaic panel 12 and the roller shutter front cover plate 60 is also filled with a sealing material, and the function of the sealing material is the same as described in Embodiment 1.

[0071] like Figure 11 As shown, a cleaning brush 61 is provided on the front cover plate 60 of the roller shutter, and the cleaning brush 61 is located at the entrance of the roller shutter box 20 for retracting the roller shutter cover 10. The cleaning brush 61 has a bristle structure and is fixedly installed on the front cover plate 60 of the roller shutter.

[0072] When the roller blind slat 11 is rolled into the roller blind box 20, the surface of the roller blind slat 11 is cleaned by the cleaning brush 61. The bristles of the cleaning brush 61 clean the surface of the roller blind slat 11, removing dust and debris, keeping the roller blind slat 11 and the photovoltaic panel 12 clean, and maintaining the power generation efficiency of the photovoltaic panel 12 and the overall performance of the roller blind device.

[0073] The solar photovoltaic panels 12 on the roller shutter slats 11 and the solar photovoltaic panels 12 on the front cover plate 60 of the roller shutter are connected in series or in parallel via flexible cables 13. The total output line 14 after the electrical connection is connected to the input end of the energy storage device 40, so as to realize the coordinated power generation of multiple solar photovoltaic panels 12, further expanding the solar power generation area and improving the overall power generation capacity.

[0074] refer to Figure 14 The device also includes a power connector 80, which is located on the main output line. The first end 81 of the power connector 80 is located on the tailgate leaf 70, and the second end 81 is located on the frame 30. The tailgate leaf 70 is linked to the roller shutter cover 10 via a hinge. When the motor pulls the roller shutter cover into the roller shutter box, the roller shutter cover moves the tailgate leaf 70, disengaging the first end 81 on the tailgate leaf 70 from the second end 81 on the frame 30. This stops the solar photovoltaic panels on the roller shutter cover from charging the energy storage device 40. Conversely, when the motor pulls the roller shutter cover out of the roller shutter box, the roller shutter cover moves the tailgate leaf 70, engaging the first end 81 on the tailgate leaf 70 with the second end 81 on the frame 30. This allows the solar photovoltaic panels on the roller shutter cover to begin charging the energy storage device 40. Alternatively, the roller shutter cover can be a manual roller shutter cover, with a torsion spring installed inside the roller shutter box to pull the roller shutter cover in and out.

[0075] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
