Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted photovoltaic module technology, and more specifically to a vehicle-mounted electrically retractable photovoltaic module device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. Photovoltaic power generation primarily uses photovoltaic (PV) panels, which are devices that generate direct current (DC) electricity when exposed to sunlight. With the development of new energy vehicles, vehicle-mounted photovoltaic power generation devices are becoming increasingly widespread. Currently, the most common installation method is to fix the solar photovoltaic panels to the roof of the vehicle using a support structure to achieve solar power generation.

[0003] However, existing vehicle-mounted electric retractable photovoltaic module devices, including photovoltaic power generation mechanisms, have a photovoltaic panel retraction mechanism inside. This mechanism uses a servo motor to control the first and second photovoltaic panels to flip and open, thus enabling rapid deployment of the photovoltaic panels. Simultaneously, the third and fourth photovoltaic panels can be extended in conjunction with the photovoltaic panel retraction mechanism, increasing the solar irradiation area and power generation. However, when the photovoltaic module frame with the photovoltaic panels is extended, the rapid movement of the frame results in poor protection for the photovoltaic panels, thus affecting subsequent use.

[0004] In addition, due to the close array of components in the photovoltaic module device and the limited space between them, there are often spaces that are inaccessible to humans when cleaning the components of the photovoltaic module device in the later stage, resulting in blind spots for cleaning and high labor intensity.

[0005] For example, patent application 202411680585.6 discloses a vehicle-mounted solar charging device that is easy to carry, including a roof rack on the roof of the vehicle and a driving protection structure on the upper part of the roof rack. The driving protection structure has a photovoltaic power generation mechanism inside. This invention provides a vehicle-mounted solar charging device that is easy to carry. The device uses a photovoltaic power generation mechanism in conjunction with a photovoltaic panel telescopic mechanism. After the vehicle stops, a servo motor is activated to control the first and second photovoltaic panels to flip open, thereby achieving rapid deployment of the photovoltaic panels. At the same time, the photovoltaic panel telescopic mechanism extends the third and fourth photovoltaic panels, increasing the light-receiving area of ​​the photovoltaic panels and thus increasing the power generation. Through the above design, the vehicle can generate electricity quickly after parking anywhere. However, the photovoltaic panels of the vehicle-mounted solar charging device disclosed in this application require a large operating space when flipping open, and the specific structure of the driving protection structure is not disclosed.

[0006] Therefore, providing a vehicle-mounted electric retractable photovoltaic module device that requires less operating space and provides good protection for photovoltaic panels has become an urgent problem to be solved in the industry. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a vehicle-mounted electrically retractable photovoltaic module device, which solves the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides a vehicle-mounted electrically retractable photovoltaic module device, including a base fixedly installed on the top of the vehicle body, an upper photovoltaic module frame mounted on the top of the base, a lower photovoltaic module frame slidably connected to the inside of the base via a slide rail, and photovoltaic panels fixedly connected to the upper and lower photovoltaic module frames.

[0009] A servo motor is mounted on the side of the base, and a lead screw is connected to the side of the servo motor. A sliding block is connected to the outside of the lead screw by a thread, and the sliding block is connected to the lower frame of the photovoltaic module.

[0010] The base is internally equipped with a buffer assembly, which includes a first hydraulic chamber and a second hydraulic chamber. A rotating disk is fixedly connected to the outer side of the lead screw, and a pressing block is fixedly connected to the outer side of the rotating disk. A hydraulic rod is slidably connected to the end of the first hydraulic chamber near the pressing block. A force-bearing block is rotatably connected to the top of the first hydraulic rod via a torsion spring. A spring is mounted on the side of the first hydraulic rod. A hydraulic rod is slidably connected to the end of the second hydraulic chamber near the pressing block. A force-bearing block is rotatably connected to the bottom of the second hydraulic rod via a torsion spring. A spring is mounted on the side of the second hydraulic rod. A friction plate is slidably connected to the end of the first hydraulic chamber away from the first hydraulic rod, and a friction clamp is slidably connected to the end of the second hydraulic chamber away from the second hydraulic rod. This design can decelerate or buffer the lower frame of the photovoltaic module, improving the protective effect of the device on the photovoltaic panels mounted on the lower frame.

[0011] Preferably, the spring is mounted on the inner wall of the hydraulic chamber on the side away from the hydraulic rod.

[0012] Preferably, the second spring is mounted on the inner wall of the hydraulic chamber on the side away from the second hydraulic rod.

[0013] Preferably, two friction plates are provided, and both friction plates are located at the bottom of the lower frame of the photovoltaic module.

[0014] Preferably, two friction plates are provided, and both friction plates are located on the side of the lower frame of the photovoltaic module.

[0015] Preferably, a cleaning assembly is mounted on the side of the base. The cleaning assembly includes a liquid pump, a pipe mounted on the side of the liquid pump, a rotating rod driven to the side of the lead screw, a sprocket fixedly connected to the outer side of the rotating rod, a chain mounted on the outer side of the sprocket, a force-bearing rod rotatably connected to the side of the base, a sprocket fixedly connected to the outer side of the force-bearing rod, a bevel gear fixedly connected to the side of the force-bearing rod near the pipe, a pipe connector rotatably connected to the side of the pipe, a bevel gear fixedly connected to the outer side of the pipe connector, and a nozzle fixedly connected to the side of the pipe connector near the lower frame of the photovoltaic module. This allows the cleaning liquid to be sprayed out in a rotating manner, increasing the coverage area of ​​the cleaning liquid on the photovoltaic panels mounted on the lower frame of the photovoltaic module, thereby improving the cleaning effect of the device.

[0016] Preferably, the end of the chain furthest from the first sprocket is fitted to the outer side of the second sprocket.

[0017] Preferably, the second bevel gear is located on the side of the first bevel gear and is in mesh with the first bevel gear.

[0018] Preferably, a stabilizing component is mounted on the side of the base. This stabilizing component includes a hydraulic chamber three. A transmission rod is slidably connected to the side of the hydraulic chamber three near the lead screw, and a pressure rod is slidably connected to the side of the hydraulic chamber three away from the transmission rod. A spring three is mounted on the side of the transmission rod, and an arc-shaped pressure plate is connected to the side of the pressure rod via a spring four and an elastic telescopic rod. This causes the pressure rod to compress the spring four and the elastic telescopic rod, applying an additional force to the arc-shaped pressure plate to prevent the lead screw from wobbling, further improving the stability of the device during use.

[0019] Preferably, the end of the spring three away from the transmission rod is mounted on the inner wall of the hydraulic chamber three.

[0020] The vehicle-mounted electrically retractable photovoltaic module device provided by this invention has the following beneficial effects:

[0021] (1) It has a double-layer photovoltaic panel. When the conditions are right, the whole vehicle is powered on to the servo motor. The servo motor pulls out the photovoltaic panel located under the frame of the photovoltaic module so that it can receive sunlight and realize the purpose of the photovoltaic panel, thereby increasing the area of ​​the vehicle photovoltaic panel and thus improving the charging efficiency of the electric vehicle.

[0022] (2) When the servo motor is started, it drives the lead screw to rotate, causing the lower frame of the photovoltaic module to extend or retract. In conjunction with hydraulic chamber one, hydraulic chamber two, rotating disk, extrusion block, hydraulic rod one, torsion spring one, force block one, spring one, hydraulic rod two, torsion spring two, force block two, spring two, friction plate and friction clamp, the lower frame of the photovoltaic module can be decelerated or buffered, which improves the protection effect of the device on the photovoltaic panels mounted on the lower frame of the photovoltaic module.

[0023] (3) During the process of extending or retracting the lower frame of the photovoltaic module, the liquid pump is activated, and in conjunction with the pipe, rotating rod, sprocket one, chain, sprocket two, force rod, bevel gear one, pipe joint, bevel gear two and nozzle, the cleaning liquid can be rotated and sprayed out, thereby increasing the coverage area of ​​the cleaning liquid on the photovoltaic panels mounted on the lower frame of the photovoltaic module, thus improving the cleaning effect of the device.

[0024] (4) When the photovoltaic panels on the lower frame of the photovoltaic module are fully opened, the hydraulic chamber three, transmission rod, pressure rod, spring three, spring four, elastic telescopic rod, and arc-shaped pressure plate work together to compress spring four and elastic telescopic rod, applying an additional force to the arc-shaped pressure plate to prevent the lead screw from shaking and further improve the stability of the device during use.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] Example 1

[0042] Please see Figures 1-5 The present invention provides a vehicle-mounted electrically retractable photovoltaic module device, including a base 100, a photovoltaic module upper frame 200 mounted on the top of the base 100, and a photovoltaic module lower frame 300 slidably connected to the inside of the base 100 via a slide rail. Photovoltaic panels are mounted on both the photovoltaic module upper frame 200 and the photovoltaic module lower frame 300.

[0043] A servo motor 400 is mounted on the side of the base 100. A lead screw 500 is connected to the transmission end of the servo motor 400. A sliding block 600 is threaded onto the outer side of the lead screw 500. The sliding block 600 is connected to the lower frame 300 of the photovoltaic module. Therefore, starting the servo motor 400... Figure 3 and Figure 4 As shown, the lead screw 500 connected to it rotates clockwise. The sliding block 600 mounted on the lead screw 500 is restricted and moves to the end away from the servo motor 400. The sliding block 600 can drive the photovoltaic module lower frame 300 connected to it to move synchronously and extend the photovoltaic panel mounted on the photovoltaic module lower frame 300.

[0044] The base 100 is internally equipped with a buffer assembly 700, which includes a first hydraulic chamber 701 and a second hydraulic chamber 702. A rotating disk 703 is fixedly connected to the outer side of the lead screw 500, and a pressing block 704 is fixedly connected to the outer side of the rotating disk 703. A hydraulic rod 705 is slidably connected to the end of the first hydraulic chamber 701 near the pressing block 704. The top of the first hydraulic rod 705 is rotatably connected to a force-bearing block 707 via a torsion spring 706. Figure 3 and Figure 4 As shown, when the lead screw 500 rotates clockwise, it drives the rotating disk 703 fixedly connected to it to rotate, so that the rotating disk 703 drives the pressing block 704 fixedly connected to it to rotate clockwise; when the pressing block 704 rotates to the force block 707, the force block 707 is pressed by the pressing block 704, and because the force block 707 is restricted by the hydraulic rod 705 in this case, the pressing block 704 drives the hydraulic rod 705 to move closer to the hydraulic chamber 701 through the force block 707.

[0045] A spring 708 is mounted on the side of hydraulic rod 705. The side of spring 708 away from hydraulic rod 705 is mounted on the inner wall of hydraulic chamber 701. A hydraulic rod 709 is slidably connected to the end of hydraulic chamber 702 near the extrusion block 704. A force-bearing block 711 is rotatably connected to the bottom of hydraulic rod 709 via a torsion spring 710. A spring 712 is mounted on the side of hydraulic rod 709. The side of spring 712 away from hydraulic rod 709 is mounted on the inner wall of hydraulic chamber 702. Figure 3 and Figure 4As shown, when the extrusion block 704 rotates clockwise, it can also extrude force block 711. At this time, force block 711 is not restricted by hydraulic rod 709, and the torque of torsion spring 710 is less than the elastic force of spring 712, causing force block 711 to rotate around torsion spring 710 as the axis, so that extrusion block 704 cannot drive hydraulic rod 709 to move through force block 711.

[0046] Two friction plates 713 are slidably connected to the end of hydraulic chamber 701 away from hydraulic rod 705. Both friction plates 713 are located at the bottom of the lower frame 300 of the photovoltaic module. Two friction plates 714 are slidably connected to the end of hydraulic chamber 702 away from hydraulic rod 709. Both friction plates 714 are located on the side of the lower frame 300 of the photovoltaic module. Sliding hydraulic rod 705 into hydraulic chamber 701 increases the pressure inside hydraulic chamber 701, causing the friction plates 713 slidably connected to hydraulic chamber 701 to move upward. This provides additional friction to the lower frame 300 of the photovoltaic module, which is moving outward at this time, reducing the moving speed of the lower frame 300 of the photovoltaic module. Similarly, starting servo motor 400... Figure 3 and Figure 4 As shown, when the lead screw 500 rotates counterclockwise, hydraulic rod 705 stops moving, while hydraulic rod 709 slides into hydraulic chamber 702 under the action of pressing block 704 and force-bearing block 711. This increases the pressure inside hydraulic chamber 702, causing the friction clamp 714, which is slidably connected to hydraulic chamber 702, to move closer to the lower frame 300 of the photovoltaic module, providing some cushioning for the rapidly retracting lower frame 300. This improves the protection of the photovoltaic panels mounted on the lower frame 300 during the activation or deactivation of the device.

[0047] When using it, start the servo motor 400, to Figure 3 and Figure 4As shown, the screw 500, which is connected to it for transmission, rotates clockwise. The sliding block 600 mounted on the screw 500, due to its constraint, moves away from the servo motor 400. The sliding block 600 then drives the photovoltaic module lower frame 300, which is connected to it, to move synchronously, extending the photovoltaic panel mounted on the lower frame 300. The clockwise rotation of the screw 500 synchronously drives the rotating disk 703, which is fixedly connected to it, to rotate. This causes the rotating disk 703 to drive the pressing block 704, which is fixedly connected to it, to rotate clockwise. When the pressing block 704 rotates to the force-bearing block 707, the force-bearing block 707 is compressed by the pressing block 704. Because the force-bearing block 707 is constrained by the hydraulic rod 705 under these conditions, the pressing block 704, through the force-bearing block 707, drives the hydraulic rod 705. 05 moves towards the side closer to hydraulic chamber 701. Simultaneously, the clockwise rotating extrusion block 704 presses against the force-bearing block 711. At this time, the force-bearing block 711 is not restricted by the hydraulic rod 709, and the torque of the torsion spring 710 is less than the elastic force of the spring 712, causing the force-bearing block 711 to rotate around the torsion spring 710 as the axis. This prevents the extrusion block 704 from driving the hydraulic rod 709 to move through the force-bearing block 711. The hydraulic rod 705 slides into hydraulic chamber 701, increasing the pressure inside hydraulic chamber 701 and causing the friction plate 713, which is slidably connected to hydraulic chamber 701, to move upward. This provides additional friction to the photovoltaic module lower frame 300 that is moving outward at this time, reducing the moving speed of the photovoltaic module lower frame 300. Similarly, the servo motor 400 is started to... Figure 3 and Figure 4 As shown, when the lead screw 500 rotates counterclockwise, the hydraulic rod 705 stops moving, while the hydraulic rod 709 slides into the hydraulic chamber 702 under the action of the pressing block 704 and the force-bearing block 711. This increases the pressure inside the hydraulic chamber 702, causing the friction plate 714, which is slidably connected to the hydraulic chamber 702, to move towards the side closer to the lower frame 300 of the photovoltaic module, thus providing a certain buffer for the rapidly retracting lower frame 300 of the photovoltaic module.

[0048] Example 2

[0049] Please see Figures 1-7Based on Embodiment 1, a cleaning assembly 800 is mounted on the side of the base 100. The cleaning assembly 800 includes a liquid pump 801, a pipe 802 mounted on the side of the liquid pump 801, and a rotating rod 803 driven by a lead screw 500. A sprocket 804 is fixedly connected to the outer side of the rotating rod 803. During the extension or retraction of the lower frame 300 of the photovoltaic module, i.e., when the lead screw 500 is rotating, the liquid pump 801 is activated to inject cleaning fluid into the pipe 802 mounted on the side of the liquid pump 801. The rotating lead screw 500 drives the rotating rod 803, which is driven by it, to rotate, causing the rotating rod 803 to drive the sprocket 804, which is fixedly connected to it, to rotate.

[0050] A chain 805 is mounted on the outer side of sprocket 1 804. A force-bearing rod 807 is rotatably connected to the side of the base 100. A sprocket 2 806 is fixedly connected to the outer side of the force-bearing rod 807. The end of the chain 805 away from sprocket 1 804 is mounted on the outer side of sprocket 2 806. A bevel gear 1 808 is fixedly connected to the side of the force-bearing rod 807 near the pipe 802. A pipe joint 809 is rotatably connected to the side of the pipe 802. A bevel gear 2 810 is fixedly connected to the outer side of the pipe joint 809. The bevel gear 2 810 is located on the side of bevel gear 1 808 and is meshed with bevel gear 1 808. A nozzle 811 is fixedly connected to the side of the pipe joint 809 near the lower frame 300 of the photovoltaic module. When sprocket 804 rotates, it engages with chain 805 mounted on the outside of sprocket 804, causing sprocket 806, which is connected to sprocket 804 via chain 805, to rotate. Sprocket 806 drives a force-bearing rod 807 fixedly connected to it to rotate, which in turn drives a bevel gear 808 fixedly connected to it to rotate. Bevel gear 808 drives a bevel gear 810 meshing with it to rotate, which in turn drives a pipe joint 809 fixedly connected to it to rotate. The pipe joint 809 then drives a nozzle 811 fixedly connected to it to rotate, spraying out the cleaning fluid injected into the nozzle 811 through pipe 802 and pipe joint 809 to clean the photovoltaic panels mounted on the lower frame 300 of the photovoltaic module. This increases the coverage area of ​​the cleaning fluid on the photovoltaic panels mounted on the lower frame 300 of the photovoltaic module, thereby improving the cleaning effect of the device.

[0051] In use, based on Example 1, during the extension or retraction of the lower frame 300 of the photovoltaic module, i.e., when the lead screw 500 is rotating, the liquid pump 801 is activated to inject cleaning fluid into the pipe 802 mounted on the side of the liquid pump 801. The rotating lead screw 500 drives the rotating rod 803, which is connected to it, to rotate. This causes the rotating rod 803 to drive the sprocket 1 804, which is fixedly connected to it, to rotate. In conjunction with the chain 805 mounted on the outside of the sprocket 1 804, the sprocket 2 806, which is connected to the sprocket 1 804 via the chain 805, rotates. The second 806 drives the force-bearing rod 807, which is fixedly connected to it, to rotate. The force-bearing rod 807 drives the bevel gear 808, which is fixedly connected to it, to rotate. The bevel gear 808 drives the bevel gear 810, which meshes with it, to rotate. The bevel gear 810 drives the pipe joint 809, which is fixedly connected to it, to rotate. The cleaning fluid injected into the nozzle 811 through the pipe 802 and the pipe joint 809 is rotated and sprayed out to perform the corresponding cleaning operation on the photovoltaic panel assembled on the lower frame 300 of the photovoltaic module.

[0052] Example 3

[0053] Please see Figures 1-9 Based on Embodiments 1 and 2, a stabilizing component 900 is mounted on the side of the base 100. The stabilizing component 900 includes a hydraulic chamber 3 901. A transmission rod 902 is slidably connected to the side of the hydraulic chamber 3 901 near the lead screw 500, and a pressure rod 903 is slidably connected to the side of the hydraulic chamber 3 901 away from the transmission rod 902. When the photovoltaic panels on the lower frame 300 of the photovoltaic module open, that is, when the lower frame 300 of the photovoltaic module moves away from the servo motor 400 along with the sliding block 600, the sliding block 600 gradually squeezes the transmission rod 902 during the movement, causing the transmission rod 902 to slide into the hydraulic chamber 3 901. This, combined with the hydraulic chamber 3 901 slidably connected to the transmission rod 902, increases the pressure inside the hydraulic chamber 3 901, driving the pressure rod 903 slidably connected to the hydraulic chamber 3 901 to move.

[0054] A spring 904 is mounted on the side of the transmission rod 902. The end of the spring 904 away from the transmission rod 902 is mounted on the inner wall of the hydraulic chamber 901. An arc-shaped pressure plate 907 is connected to the side of the pressure rod 903 via a spring 905 and an elastic telescopic rod 906. When the lower frame 300 of the photovoltaic module moves to the limit position away from the servo motor 400 along with the sliding block 600, the arc-shaped pressure plate 907 is stationary due to the compression of the lead screw 500. The continuing movement of the pressure rod 903 can compress the spring 905 and the elastic telescopic rod 906, thereby applying an additional force to the arc-shaped pressure plate 907 to prevent the lead screw 500 from shaking, further improving the stability of the device during use.

[0055] When the lower frame 300 of the photovoltaic module retracts, the transmission rod 902 loses the restraint of the sliding block 600 and can be reset under the action of the spring 904. In this way, the stabilizing module 900 can be fully reset so that it can be used again.

[0056] In use, based on Embodiments 1 and 2, when the photovoltaic panels on the lower frame 300 of the photovoltaic module open, that is, when the lower frame 300 of the photovoltaic module moves away from the servo motor 400 along with the sliding block 600, the sliding block 600 gradually squeezes the transmission rod 902 during the movement, causing the transmission rod 902 to slide into the hydraulic chamber 3 901. This, combined with the hydraulic chamber 3 901 which is slidably connected to the transmission rod 902, increases the pressure within the hydraulic chamber 3 901, driving the pressure rod 903 which is slidably connected to the hydraulic chamber 3 901 to move. The pressure rods 903 on both sides move towards each other, causing... When the movable arc-shaped pressure plate 907 moves to the lead screw 500, and the lower frame 300 of the photovoltaic module moves to the extreme position away from the servo motor 400 along with the sliding block 600, the arc-shaped pressure plate 907 is stationary due to the pressure on the lead screw 500. The continuing to move pressure rod 903 can compress the spring 905 and the elastic telescopic rod 906, thereby applying an additional force to the arc-shaped pressure plate 907 to prevent the lead screw 500 from shaking. When the lower frame 300 of the photovoltaic module retracts, the transmission rod 902 loses the restriction of the sliding block 600 and can be reset under the action of the spring 904.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
