Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a solar-powered doorplate light. Background Technology

[0002] Currently, solar-powered doorplate lights are doorplate lighting devices that utilize solar energy resources for power supply. They combine the advantages of solar photovoltaic power generation technology and LED lighting technology, and are characterized by energy saving, environmental protection, easy installation, safety and reliability. They are often used in various places that require doorplate lighting, such as commercial streets, industrial parks, residential communities, schools, hospitals and so on.

[0003] However, currently, when using solar-powered nameplate lights, the solar panels are installed on top of the light and exposed to the outdoor environment without any other protective mechanisms. This means that in rainy weather, rainwater carrying dust and impurities drips onto the surface, obstructing the solar panels and affecting their efficiency in absorbing and converting solar energy. This also significantly shortens the overall lifespan of the nameplate. Therefore, we propose a new type of solar-powered nameplate light. Utility Model Content

[0004] The main purpose of this utility model is to provide a solar-powered doorplate light that can effectively solve the problems in the background technology.

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

[0006] A solar-powered doorplate light, wherein a light frame is fixedly embedded inside the mounting frame, and a solar panel is fixedly installed at an angle on the top side of the mounting frame;

[0007] The mounting frame is fixedly installed on both sides of the top, and a folding baffle is movably installed between the outer sides of the two sets of fixed frames, with the folding baffle movably located at the top of the outer side of the solar panel.

[0008] The fixed frame is equipped with a push-pull mechanism, and the outside of the push-pull mechanism is connected to the outside of the folding baffle through a connecting mechanism.

[0009] By adopting the above technical solution, the folding baffle can be folded and unfolded through the push-pull mechanism. While not affecting the normal absorption of external sunlight by the solar panel, it can also provide protection by shielding the solar panel from the top in rainy weather. This prevents external rainwater from carrying dust and impurities from dripping onto the surface of the solar panel and obstructing its absorption and conversion efficiency, thus extending the overall lifespan of the solar sign light.

[0010] As an optional solution to the technical solution of this application, the push-pull mechanism includes a rotating lead screw. A rotating lead screw is rotatably mounted inside each of the fixed frames via bearings. A servo motor is fixedly mounted on the inner side of each fixed frame near the mounting frame, and the side of the servo motor drive shaft is fixedly connected to the side of the rotating lead screw via a coupling. A movable sleeve is threadedly fitted onto the outer surface of each rotating lead screw. A fixed rod is fixedly mounted on the outer side of each movable sleeve. A limit groove is formed on the side of each fixed frame, and the fixed rod slides through and is inserted into the limit groove. A connecting rod is fixedly mounted on the outer end of each fixed frame near the mounting frame. Fixed plates are fixedly mounted on both ends of the folding baffle near the mounting frame, and the side of the connecting rod is rotatably inserted into the fixed plate via bearings.

[0011] By adopting the above technical solution, the rotational transmission of the movable sleeve by the rotating screw can provide a corresponding pushing force to the front end of the folding baffle, so that the front end of the folding baffle can move horizontally back and forth synchronously with the horizontal movement of the movable sleeve, thereby enabling the folding baffle to be folded and unfolded.

[0012] As an optional solution to the technical solution of this application, the connecting mechanism includes a connecting sleeve, a connecting plate is fixedly installed on the side of each fixed rod away from the movable sleeve, a rotating rod is rotatably installed on the side of each connecting plate through a bearing, a connecting sleeve is fixedly sleeved on the outer surface of each rotating rod, and the outer side of the connecting sleeve and the side of the folding baffle away from the mounting frame are fixedly connected.

[0013] By adopting the above technical solution, the rotation of the rotating rod ensures that the connection of the folding baffle can rotate relative to each other when pushed or pulled, thus ensuring the rationality of folding and storage.

[0014] As an optional solution to the technical solution of this application, a rain sensor is fixedly installed on the outer side of the fixed frame away from the mounting frame, and a controller is fixedly installed on the bottom side of the mounting frame. The signal output terminal of the rain sensor and the signal input terminal of the controller are electrically connected, and the signal output terminal of the controller and the signal input terminal of the servo motor are electrically connected.

[0015] By adopting the above technical solution, the rainfall in the external environment is detected by the rain sensor, and the operation of the servo motor can be automatically controlled under the control and analysis of the controller. This improves the automaticity of the folding baffle in protecting and adjusting the solar panel, and further enhances the protection of the solar panel.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A solar-powered doorplate light according to the present application, wherein a corrugated folding baffle is provided between the outer sides of a fixed frame, and under the connecting transmission action of a rotatable connecting rod and a rotating rod, a rotating screw located inside the fixed frame outside the folding baffle rotates, and under the rotational transmission action of the movable sleeve, the movable sleeve moves horizontally synchronously inside the fixed frame. Under the connecting transmission action of the fixed rod, a corresponding pushing force can be provided to the front end of the folding baffle, so that the front end of the folding baffle can move horizontally back and forth synchronously with the horizontal movement of the movable sleeve. Thus, the folding baffle can be folded and unfolded. While not affecting the normal absorption of external ambient light by the solar panel, in rainy weather, it can provide protection by shielding the top of the solar panel, preventing external rainwater carrying dust and impurities from dripping onto its surface and obstructing the surface of the solar panel, affecting the absorption and conversion efficiency of external solar energy, and extending the service life of the overall solar-powered doorplate light.

[0018] 2. A solar-powered doorplate light according to the technical solution of this application, by setting a rain sensor on the outside of the fixed frame, can monitor the rainfall in the external environment. Then, after the controller converts and analyzes the signal transmitted by the rain sensor, it can realize the automatic control of the operation of the servo motor, thereby improving the automatic adjustment of the folding baffle to protect the solar panel and further improving the protection of the solar panel.

Multiple sets of LED light columns are set inside the light frame 11 to realize the illumination display of the doorplate. A solar panel 12 is fixedly installed at an angle on the top side of the mounting frame 1. After the solar panel 12 absorbs the light from the external environment, it converts the light energy into electrical energy in combination with other conversion elements to power the doorplate light inside the light frame 11 and the servo motor 24.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a rain sensor 4 is fixedly installed on the outer side of the fixed frame 2 away from the mounting frame 1. A controller 41 is fixedly installed on the bottom side of the mounting frame 1. The signal output terminal of the rain sensor 4 is electrically connected to the signal input terminal of the controller 41. The signal output terminal of the controller 41 is electrically connected to the signal input terminal of the servo motor 24.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, fixed frames 2 are fixedly installed on both sides of the top of the mounting frame 1. A folding baffle 21 is movably installed between the outer sides of the two sets of fixed frames 2, and the folding baffle 21 is movably located on the top of the outer side of the solar panel 12. A push-pull mechanism is provided inside the fixed frame 2. The push-pull mechanism includes a rotating screw 22. A servo motor 24 is fixedly installed on the inner side of each fixed frame 2 near the mounting frame 1. The transmission shaft side of the servo motor 24 is fixedly connected to the side of the rotating screw 22 through a coupling. A rotating screw 22 is rotatably installed inside each fixed frame 2 through a bearing. A movable sleeve 23 is movably sleeved on the outer surface of each rotating screw 22 through a thread. A fixed rod 26 is fixedly installed on the outer side of each movable sleeve 23. A limit groove 25 is opened on the side of each fixed frame 2, and the fixed rod 26 is slidably inserted into the limit groove 25.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a connecting rod 34 is fixedly installed on the outer side of the fixed frame 2 near the mounting frame 1, and a fixing plate 33 is fixedly installed on both ends of the folding baffle 21 near the mounting frame 1, and the side of the connecting rod 34 is rotatably inserted into the fixing plate 33 through a bearing.

[0027] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown, the outer side of the push-pull mechanism is connected to the outer side of the folding baffle 21 via a connecting mechanism. The connecting mechanism includes a connecting sleeve 32. A connecting plate 3 is fixedly installed on the side of each fixed rod 26 away from the movable sleeve 23. A rotating rod 31 is rotatably installed on the side of each connecting plate 3 via a bearing. A connecting sleeve 32 is fixedly sleeved on the outer surface of each rotating rod 31, and the outer side of the connecting sleeve 32 is fixedly connected to the side of the folding baffle 21 away from the mounting frame 1.

[0028] During operation, the mounting frame 1 and the light frame 11 are simultaneously installed on the outdoor wall surface to be illuminated. After the solar panel 12 absorbs the sunlight from the external environment, it converts the light energy into electrical energy with the help of other conversion elements to power the signboard light and servo motor 24 inside the light frame 11. When there is heavy rainfall, the rain sensor 4 detects the rainfall and transmits the rainfall information to the controller 41. The controller 41 then converts and analyzes the rainfall information. If the rainfall exceeds the set threshold, the servo motor 24 is activated, causing the rotating screw 22 to rotate synchronously. Combined with the guiding and limiting effect of the limit groove 25 on the fixed rod 26, The system can provide a corresponding pushing force to the front end of the folding baffle 21, so that the front end of the folding baffle 21 can move horizontally forward synchronously with the horizontal movement of the movable sleeve 23, thereby allowing the folding baffle 21 to be unfolded. While not affecting the normal absorption of external ambient light by the solar panel 12, it can also provide protection by shading the top of the solar panel 12. After the weather changes to a sunny environment, the above steps are repeated, so that the front end of the folding baffle 21 can move horizontally backward synchronously with the horizontal movement of the movable sleeve 23, thereby allowing the folding baffle 21 to retract along the corrugated fold lines on its surface to the rear side of the solar panel 12, thus avoiding affecting the energy conversion efficiency of the solar panel 12 in absorbing and converting external ambient light.
