Description

Technical Field

[0001] The utility model relates to the technical field of solar lighting, in particular to a mini solar flashlight. Background Art

[0002] Flashlights are common lighting tools used by people in daily life. Traditional flashlights generally use dry batteries as power sources. Since dry batteries are consumables and need to be replaced frequently, users are required to always have dry batteries or be able to purchase dry batteries at any time, otherwise the flashlight will not be usable, and the replaced dry batteries are often directly thrown away, causing environmental pollution. To solve this problem, people have manufactured solar flashlights. However, existing solar flashlights only have solar panels installed on one side. Since sufficient light energy needs to be converted into electrical energy to meet the long-term power supply requirements of the flashlight, the solar panel needs to be relatively large in size. The overall size of the flashlight is also relatively large due to the limitation of the solar panel, which is inconvenient to carry and store. Utility Model Content

A push block 31 is arranged on the inner side of the solar panel 3, and a pressing plate 4 is installed at the tail of the flashlight body 1, and the pressing plate 4 has the freedom of linear motion along the length direction of the flashlight body 1. When the pressing plate 4 moves inward, its edge pushes the push block 31 to rotate the solar panel 3 so that it opens outward, and when the pressing plate 4 moves outward, its edge pushes the inner wall of the solar panel 3 to retract the solar panel 3 inward.

[0026] In the above embodiment, by arranging solar panels 3 on each face of the polygonal outer surface of the flashlight body 1, the total area of ​​the solar panels 3 on the flashlight is increased, so that it can meet the power supply demand of the flashlight for long-term lighting. When storing energy, it is only necessary to push the solar panels 3 to rotate and open them outward through the pressing plate 4, so that all solar panels 3 can receive light at the same time, thereby converting light energy into electrical energy and storing it in the battery in the flashlight body 1. After the power storage is completed, the pressing plate 4 is reset outward to make the solar panels 3 retract inward, so that the flashlight is easy to store and carry. Compared with ordinary solar flashlights, the overall volume of the solar flashlight provided by this embodiment is greatly reduced.

[0027] Preferably, a first groove 11 is formed on each surface of the flashlight body 1 , and the solar panel 3 enters the first groove 11 when the solar panel 3 is folded.

[0028] In the above embodiment, the solar panel 3 is stored in the first groove 11 when folded, which can prevent the solar panel from being damaged during storage and carrying, and also make the outer surface of the flashlight smoother and more beautiful.

[0029] Preferably, a second groove 12 is formed at the bottom of the flashlight body 1 , a guide column 13 is provided in the second groove 12 , and the pressing plate 4 can slide on the guide column 13 .

[0030] In the above embodiment, the guide column 13 is used to guide the linear motion of the pressing plate 4, so that the forward and backward motion of the pressing plate 4 is more stable and smooth.

[0031] Preferably, a rear cover 5 is installed at the free end of the guide column 13 , and the rear cover 5 is located outside the pressure plate 4 . The rear cover 5 and the guide column 13 are connected by threads, and a compression spring 6 is installed between the pressure plate 4 and the bottom surface of the second groove 12 .

[0032] In the above embodiment, the pressure plate 4 can be pushed inward by screwing the back cover 5 inward, thereby pushing the solar panel 3 to open. At this time, the compression spring 6 is compressed. When the back cover 5 is screwed outward, the restoring elastic force of the compression spring 6 pushes the pressure plate 4 to move outward, thereby driving the solar panel 3 to retract. The opening and closing process of the solar panel 3 only requires rotating the back cover 5, which is simple to operate.

[0033] Preferably, a guide portion 41 is provided on the inner side of the pressure plate 4 , and the guide portion 41 is located between the inner diameter of the compression spring 6 and the outer circumference of the guide column 13 .

[0034] In the above embodiment, adding the guide portion 41 to the pressing plate 4 can further increase the stability of the movement of the pressing plate 4 .

[0035] Preferably, chamfers 32 are provided on both sides of one end of the solar panel 3 close to the flashlight body 1 .

[0036] In the above embodiment, chamfers 32 are provided on both sides of the solar panel 3, so that the width of the solar panel 3 can be closer to the side length of the cross section of the flashlight body 1 without interfering with the adjacent solar panel 3 when opened, thereby making maximum use of the outer surface of the flashlight body 1 to arrange the solar panel 3.

[0037] Preferably, a hook 51 is provided on the rear cover 5 .

[0038] In the above embodiment, a hook 51 is provided on the rear cover 5 so that the flashlight can be hung on a key ring or the like for easy carrying.

[0039] Preferably, a rotating shaft 33 is provided on both sides of the solar panel 3 , and the rotating shaft 33 is mounted on the flashlight body 1 .

[0040] In the above embodiment, the solar panel 3 is mounted on the flashlight body 1 via the rotating shaft 33 , so that the solar panel 3 can rotate on the flashlight body 1 more smoothly.

[0042] In the above embodiment, a avoidance groove 34 is opened between the push block 31 and the inner wall of the solar panel 3, which can make the overall structure of the flashlight more compact and avoid interference between the edge of the pressing plate 4 and the push block 31 and the solar panel 3 during the inward movement of the pressing plate 4. The edge of the pressing plate 4 is semicircular, and the bottom of the avoidance groove 34 is an arc with a radius not less than the radius of the edge of the pressing plate 4, which can make the inward movement of the pressing plate 4 smoother.
