Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted device technology, specifically a vehicle-mounted photovoltaic power supply. Background Technology

[0002] A photovoltaic (PV) power source is a device that converts solar energy into electrical energy, primarily through the photovoltaic effect. Its core component is the solar panel. When sunlight shines on the solar panel, photons excite electrons in the photovoltaic material, thereby generating an electric current and converting light energy into electrical energy. A PV power system typically consists of solar panels, battery packs, an inverter, and grid connection equipment.

[0003] Existing vehicle-mounted photovoltaic power supplies are inconvenient to install and fix on the vehicle body in actual use. They do not have an automatic folding and unfolding function. They are basically carried with the vehicle and have to be taken out of the vehicle and unfolded to generate electricity when needed. This is not convenient and it is difficult to use while the vehicle is in motion. The angle at which the photovoltaic panels receive sunlight cannot be adjusted as needed. Utility Model Content

[0004] To address the shortcomings of the existing technology, the present invention aims to provide a vehicle-mounted photovoltaic power supply that can be securely clamped and fixed to the roof rack, facilitating installation and disassembly. It can automatically unfold and store two solar panels, control the rotation of the solar panels to a suitable angle as needed, and stably maintain the optimal angle of light reception. It also features high structural strength and improves the power generation efficiency of the solar panels.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A vehicle-mounted photovoltaic power supply is provided, including a storage box. Two crossbars are fixedly installed at the bottom of the storage box, and two sets of clamping plates are installed on the crossbars. An adjustment plate is slidably engaged on both sides of the storage box.

[0007] Two first electric push rods are fixed on the two inner side walls of the storage box. The output directions of the two first electric push rods are opposite and their output ends are respectively fixedly connected to the two adjustment plates.

[0008] Two guide rods are provided on one side of the adjustment plate, and a horizontal plate is fixed between the two guide rods. A solar panel is rotatably connected between the horizontal plate and the adjustment plate.

[0009] A servo motor for driving the solar panel to rotate is fixed to one outer end face of the adjustment plate, and a locking frame for limiting the rotation of the solar panel is fixed to one side of the horizontal plate.

[0010] Furthermore, the storage box has side doors on both sides, and two sliding grooves are opened on the two inner side walls of the storage box. The two sliding grooves are vertically distributed, and the guide rod is slidably engaged on the inner side of the sliding groove. The solar panel slides in and out of the storage box through the side doors, and the two solar panels are stacked alternately on the inner side of the storage box.

[0011] Furthermore, a sealing gasket is fixed to the inner side of the adjustment plate, the output end of the servo motor is fixedly connected to a rotating shaft of the solar panel, and a waterproof housing is fixed to the outer side of the adjustment plate, with the servo motor located inside the waterproof housing.

[0012] Furthermore, another rotating shaft of the solar panel passes through the horizontal plate and is fixed with a friction head. A movable plate is slidably fitted inside the locking frame. A locking cover is fixed on one side of the movable plate. One end of the friction head is located inside the locking cover. The friction head has a frustum-shaped structure. The periphery of the frustum-shaped structure is provided with anti-slip texture. The locking cover is provided with a frustum-shaped braking groove that matches the friction head.

[0013] Furthermore, a second electric push rod is fixed to the inner side wall of the locking frame, and the output end of the second electric push rod is fixedly connected to one side of the movable plate.

[0014] Furthermore, limit grooves are provided on both sides of the locking frame, and a slide rod is fixed in the limit groove. The two ends of the movable plate are slidably engaged in the inner side of the limit groove, and the end of the movable plate is slidably sleeved on the outer side of the slide rod.

[0015] Furthermore, the bottom of the storage box is fixed with two sets of base plates, and the two crossbars are respectively fixed inside the two sets of base plates. The top of each set of clamping plates is clamped and fixed on the crossbars. One set of screws is fixed on one side of one of the clamping plates, and one end of the screw passes through the other clamping plate and is fitted with a nut.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The vehicle-mounted photovoltaic power supply of this utility model can automatically unfold and store two solar panels through a storage box, so that the two solar panels are stacked alternately in the storage box, which plays a role in protecting the solar panels and preventing the solar panels from being damaged by rain, snow and ice, thus improving the service life of the solar panels.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Furthermore, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0035] Example: Reference Figure 1-8 The vehicle-mounted photovoltaic power supply shown includes a storage box 1. Two crossbars 4 are fixedly installed at the bottom of the storage box 1. Two sets of clamping plates 5 are installed on the crossbars 4. An adjustment plate 2 is slidably fitted on both sides of the storage box 1.

[0036] Two first electric push rods 9 are fixed on the two inner side walls of the storage box 1. The output directions of the two first electric push rods 9 are opposite and their output ends are respectively fixedly connected to the two adjustment plates 2.

[0037] Two guide rods 10 are provided on one side of the adjustment plate 2, and a horizontal plate 15 is fixed between the two guide rods 10. A solar panel 11 is rotatably connected between the horizontal plate 15 and the adjustment plate 2.

[0038] A servo motor 14 for driving the solar panel 11 to rotate is fixed on one outer end face of the adjusting plate 2, and a locking frame 16 for limiting the rotation of the solar panel 11 is fixed on one side of the horizontal plate 15.

[0039] The bottom of the storage box 1 is fixed with two sets of base plates 3, and two crossbars 4 are fixed to the inner side of the two sets of base plates 3 respectively. The top of each set of clamping plates 5 is clamped and fixed on the crossbars 4. One set of screws 6 is fixed on one side of one clamping plate 5. One end of the screws 6 passes through the other clamping plate 5 and is fitted with a nut.

[0040] When using this vehicle-mounted photovoltaic power source, the storage box 1 can be fixed to the roof of the vehicle by four sets of clamping plates 5, so that the bottom of the clamping plates 5 is clamped and fixed to the roof rack. By tightening the nuts on the screws 6, the top of each set of clamping plates 5 can be tightly clamped to the crossbar 4, and the bottom of each set of clamping plates 5 can be tightly clamped to the roof rack, thus completing the installation of the photovoltaic power source.

[0041] The power output terminal of the solar panel 11 can be electrically connected to the car battery to charge the vehicle battery, or the power output terminal of the solar panel 11 can be electrically connected to its energy storage device or other electrical equipment in the vehicle to supply power to the vehicle.

[0042] When photovoltaic power generation is needed, both first electric push rods 9 located at the top and bottom are activated. The two first electric push rods 9 will push the two adjusting plates 2 to move horizontally, so that the two adjusting plates 2 can slide out stably from the inside of the storage box 1 to both sides. Then, the servo motor 14 is activated to control the solar panel 11 to rotate at a suitable angle, so that the light shines vertically on the solar panel 11, thereby improving the power generation efficiency of the solar panel 11. After the angle of the solar panel 11 is adjusted, the locking frame 16 will fix one of the rotating shafts of the solar panel 11 to prevent the solar panel 11 from deflecting, so that the solar panel 11 can stably maintain the best light-receiving angle and improve the structural strength of the solar panel 11.

[0043] To ensure the two adjusting plates 2 can be stacked and stored inside the storage box 1, and the solar panel 11 can stably enter and exit the storage box 1, in this embodiment, side doors 7 are provided on both sides of the storage box 1, and two sliding grooves 8 are provided on both inner side walls of the storage box 1. The two sliding grooves 8 are vertically distributed, and the guide rod 10 is slidably engaged with the inner side of the sliding grooves 8. The solar panel 11 slides in and out of the storage box 1 through the side doors 7, and the two solar panels 11 are stacked alternately inside the storage box 1. Through the sliding engagement of the sliding grooves 8 and the guide rod 10, the solar panel 11 can slide out horizontally, and the structural strength of the adjusting plate 2 is improved.

[0044] Furthermore, in this embodiment, a sealing gasket 12 is fixed on the inner side of the adjustment plate 2. The sealing gasket 12 allows the adjustment plate 2 to be in close contact with the end face of the storage box 1, thereby sealing the side door 7 tightly and preventing rainwater and dust from entering the storage box 1. The output end of the servo motor 14 is fixedly connected to a rotating shaft of the solar panel 11, and a waterproof housing 13 is fixed on the outer side of the adjustment plate 2. The servo motor 14 is located inside the waterproof housing 13, which protects the servo motor 14.

[0045] In order to fix one shaft of the solar panel 11 to the locking frame 16, in this embodiment, the other shaft of the solar panel 11 passes through the horizontal plate 15 and is fixed with a friction head 20. A movable plate 17 is slidably fitted inside the locking frame 16. A locking cover 18 is fixed on one side of the movable plate 17. One end of the friction head 20 is located inside the locking cover 18. The friction head 20 has a frustum-shaped structure. The peripheral side of the frustum-shaped structure is provided with anti-slip texture. The locking cover 18 is provided with a frustum-shaped braking groove that matches the friction head 20. A second electric push rod 19 is fixed on the inner wall of the locking frame 16. The output end of the second electric push rod 19 is fixedly connected to one side of the movable plate 17. After the angle of the solar panel 11 is adjusted, the second electric push rod 19 is activated and pushes the movable plate 17 toward the horizontal plate 15. The locking cover 18 moves toward the friction head 20, and the friction head 20 extends into the interior of the locking cover 18. Through the squeezing contact between the inner wall of the locking cover 18 and the peripheral side of the friction head 20, the friction force of the contact surface between the two is increased, thereby achieving the purpose of fixing the rotating shaft of the solar panel 11, preventing the solar panel 11 from deflecting, and enabling the solar panel 11 to stably maintain the optimal light-receiving angle.

[0046] In order to enable the movable plate 17 and the locking cover 18 to move horizontally stably, in this embodiment, the two side walls of the locking frame 16 are provided with limiting grooves 21, and a sliding rod 22 is fixed in the limiting groove 21. The two ends of the movable plate 17 are respectively slidably engaged in the inner side of the limiting groove 21, and the end of the movable plate 17 is slidably sleeved on the outer side of the sliding rod 22. The setting of the sliding rod 22 enables the movable plate 17 to move horizontally in the inner side of the limiting groove 21, thereby improving the stability of the movable plate 17 when sliding.

[0047] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
