Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a foldable solar-powered emergency lighting device. Background Technology

[0002] Solar energy, as a green and renewable resource that is energy-saving and environmentally friendly, has been applied to various aspects of daily life, and its application in lighting technology is even more widespread. The solar wall light involved in this application can be applied to outdoor buildings requiring localized lighting, such as home courtyards, parks, scenic spots, and community walls.

[0003] In the prior art, such as Chinese Patent Publication No. CN221629692U, a foldable solar wall lamp is disclosed, comprising: a mounting plate; a first plate-shaped main body, one end of which is pivotally connected to the mounting plate, and the other end of which is pivotally connected to a second plate-shaped main body; a light source assembly disposed on the second plate-shaped main body; a photovoltaic panel disposed on the first plate-shaped main body, the photovoltaic panel being connected to a storage battery, and the storage battery being electrically connected to the light source assembly; both the mounting plate and the second plate-shaped main body can rotate relative to the first plate-shaped main body to fold and be stored in the side of the first plate-shaped main body. In this solar wall lamp, the first plate-shaped main body can rotate at a certain angle relative to the mounting plate to allow the photovoltaic panel to receive sunlight, and the second plate-shaped main body can rotate at a certain angle relative to the first plate-shaped main body to allow the light source assembly to illuminate a preset position. When storage or transportation is required, both the mounting plate and the second plate-shaped main body can be folded and stored in the side of the first plate-shaped main body. In this folded state, the solar wall lamp is small in size and thin, making it easy to store and transport.

[0004] All the solar wall lamps mentioned in the aforementioned patent applications have their sensors mounted on the light-emitting panel. When the light-emitting panel rotates to adjust the light emission angle, the sensor also rotates with the panel, which affects the sensing distance and angle. To achieve good sensing functionality, this conversely limits the illumination angle range of the light-emitting panel, causing some inconvenience for users. Utility Model Content

[0005] To solve the above-mentioned technical problems, a foldable solar emergency lighting device is provided. This technical solution solves the problem mentioned in the background technology that when the light-emitting panel rotates, its sensing device will also rotate with the light-emitting panel.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0035] Reference Figure 1-4As shown, a foldable solar-powered emergency lighting device includes: a positioning shaft 1, serving as the basic positioning component of the device; two sets of fixing discs 9, fixedly installed inside the positioning shaft 1 near the left and right ends; a fixing cylinder 12, installed at the middle of one end of the shaft surface of the fixing disc 9; a first insert rod 13, inserted into the inside of the shaft surface of the fixing cylinder 12; a rotating ring 2, the outer surface of which is inserted through the front section of the shaft surface of the first insert rod 13 and the outer surface of the positioning shaft 1; and a knob 14, the outer surface of which is inserted through the front section of the shaft surface of the first insert rod 13 and the outer surface of the rotating ring 2. The shaft surface has a finger groove 15 at the top, an inner rotating plate 3 is fixedly installed on the front section of the rotating ring 2 shaft surface, an outer rotating plate 4 is set at one end of the outer surface of the inner rotating plate 3, a mounting plate 5 is installed on the front section of the positioning shaft 1 shaft surface, a spring 10 is installed on the outer surface of the fixed plate 9 and located at the other end of the fixed cylinder 12, a movable plate 11 is fixedly installed on the front section of the outer surface of the spring 10, a positioning groove 16 is opened in the middle of the rear end of the outer surface of the positioning shaft 1 and located between the two sets of movable plates 11, and a photosensitive device 6 is installed on the front section of the outer surface of the mounting plate 5.

[0036] The above-described device uses a positioning shaft 1 as its core component. Two sets of fixed discs 9 are fixedly installed at its left and right ends. A fixed cylinder 12 is mounted in the middle of each fixed disc 9, and a first insert rod 13 is inserted into the cylinder. The front end of the first insert rod 13 passes through the positioning shaft 1 and the rotating ring 2, and the end connects to a knob 14 with a finger groove 15, forming a rotation locking hub. An inner rotating plate 3 is fixed to the front end of the rotating ring 2, and an outer rotating plate 4 extends outward from the inner rotating plate 3, forming a folding frame. A mounting plate 5 is installed at the front end of the positioning shaft 1 to support the functional modules. A spring 10 is installed on the other side of the fixed disc 9, with its front end connected to a moving disc 11. A positioning groove 16 is opened at the rear end of the positioning shaft 1 for the moving disc 11 to lock in place, achieving elastic locking in the folded state. A photosensitive sensor 6 is installed at the front of the mounting plate 5 to automatically control the lighting start and stop.

[0037] Reference Figure 1-3 As shown, positioning piles 19, in several groups, are fixedly installed on one side of the outer surface of the inner rotating plate 3. The second insert rod 17 is installed on the outer surface of the mounting plate 5 near the end of the positioning piles 19. The positioning piles 19 are inserted into the shaft surface. The limiting plate 7 is fixedly installed at the top of the outer surface of the mounting plate 5. The solar panel 8 is set at the bottom of the outer surface of the limiting plate 7.

[0038] Through the above scheme, multiple sets of positioning stakes 19 are fixed to the side of the inner rotating plate 3, and the second insertion rod 17 is installed at the corresponding position on the mounting plate 5. When unfolded, the second insertion rod 17 is inserted into the positioning stakes 19 to ensure structural stability. The top of the mounting plate 5 is fixed with a limiting plate 7, and a solar panel 8 is laid at its bottom. The limiting plate 7 constrains the angle of the solar panel 8 to maximize light energy collection. The solar panel 8 converts light energy into electrical energy for storage for emergency use at night.

[0039] Reference Figure 3-4As shown, the rotating shaft 20 is inserted into the rear end of the mounting plate 5. The rotating shaft 20 is inserted into the shaft surface of the lamp back plate 24. The lamp 18 is installed on the top of the outer surface of the lamp back plate 24. The fastener 22 is installed on the bottom of the front section of the outer surface of the lamp back plate 24. The positioning rod 21 has the fastener 22 snapped onto its top surface. Both ends of the shaft surface are set at the bottom of the inner end of the mounting plate 5. The handle 23 has the fastener 22 fixedly installed on its top surface.

[0040] With the above solution, the rear end of the mounting plate 5 is connected to the rotating shaft 20, and the lamp back plate 24 is sleeved with the rotating shaft 20 to achieve rotation adjustment. The lamp 18 is installed at the top of the back plate to provide lighting. The bottom of the lamp back plate 24 is provided with a buckle 22, which is engaged with the positioning rod 21 at the bottom of the mounting plate 5 to fix the lighting angle. When folding, the buckle 22 is released, and the lamp back plate 24 is rotated inward to fit the mounting plate 5. At the same time, the inner rotating plate 3 and the outer rotating plate 4 are stacked and folded together. Finally, the moving plate 11 is locked into the positioning groove 16 to lock the whole into a flat state, which greatly reduces the volume and makes it easy to carry.

[0041] Working principle and implementation: The user first fixes the mounting plate 5 with wall screws or adhesive, ensuring that the photosensor 6 faces the monitoring area. When unfolding, pull the inner rotating plate 3 and outer rotating plate 4 assembly outward, and rotate the knob 14 to lock the unfolding angle through the linkage of the first insert rod 13 and the rotating ring 2; at this time, the positioning stake 19 automatically inserts into the second insert rod 17 on the mounting plate 5 to ensure structural stability. Then adjust the lighting direction: rotate the lamp back plate 24 around the rotating shaft 20 to the target angle, such as wall washing or ground projection, and press down to make the buckle 22 engage and fix with the positioning rod 21 at the bottom of the mounting plate 5. Under the constraint of the limiting plate 7, the solar panel 8 continuously absorbs and stores light energy, and the photosensor 6 detects the ambient brightness in real time. When the light is below the threshold, the lamp 18 automatically starts to illuminate. When storing, pull up the buckle 22 to release the angle lock of the lamp 18, and flip the lamp back plate 24 inward to fit the mounting plate 5; loosen the knob 14, push the inner rotating plate 3 and the outer rotating plate 4 to overlap, at which time the spring 10 pushes the moving disk 11 to embed into the positioning groove 16 of the positioning shaft 1, realizing mechanical self-locking, and finally forming a flat structure with uniform thickness, which is convenient for transportation or storage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
