Description

Technical Field

[0001] This utility model relates to the field of mobile phone peripheral products technology, and in particular to a solar-powered hand-cranked mountaineering flashlight. Background Technology

[0002] Chinese utility model patent application number 202210101308X discloses a flashlight body structure and a flashlight. The flashlight body structure includes a body shell, a power supply component, and a tail cap. The body shell has a button and a light guide. The body shell has a receiving hole, and multiple perforated posts are spaced apart on the inner wall of the receiving hole. Each perforated post has a threaded hole at both ends, with one threaded hole used to connect to a lamp head. The power supply component is disposed in the receiving hole and abuts against the perforated post. The tail cap is disposed at the end of the body shell away from the lamp head and connected to the threaded hole.

[0003] Different situations create scenarios that necessitate various flashlight alternatives. For example, outdoor use may require a bright flashlight with a long illumination time. In this scenario, the size of the flashlight may not be important, which is preferable because flashlights with longer illumination times and greater brightness are generally larger. However, in other situations, portability is paramount when using a smaller, lower-brightness flashlight. Thus, a wide variety of flashlights exist, each designed to meet the needs of different scenarios. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a solar-powered hand-cranked mountaineering flashlight, which allows for charging of the flashlight's battery in two ways and is suitable for various outdoor environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solar-powered hand-cranked mountaineering flashlight, mainly comprising: a light-emitting lamp assembly, a battery pack, a flashlight shell, a solar panel, a hand-crank button, and an electromagnetic generator. The light-emitting lamp assembly is installed at the front end of the flashlight shell. The battery pack is electrically connected to the light-emitting lamp assembly, the electromagnetic generator, and the solar panel. The solar panel is fixed to the outer surface of the flashlight shell. The hand-crank button is located on one side of the flashlight shell. The hand-crank button drives the rotating magnet of the electromagnetic generator to rotate through a transmission gear.

[0006] Specifically, the hand-crank button extends into the flashlight housing at both the top and bottom. The hand-crank button is equipped with a round shaft sleeve, which is installed inside the flashlight housing via a pivot. Torsion springs are sleeved on both sides of the round shaft sleeve. One end of the torsion spring abuts against a fixed rod inside the flashlight housing, and the other end of the torsion spring abuts against a horizontal bar extending from the hand-crank button into the flashlight housing.

[0007] Specifically, the bottom of the hand-cranked button is an arc-shaped push rod, and one side of the arc-shaped push rod is provided with teeth. The teeth mesh with the transmission gear, and the arc-shaped push rod drives the transmission gear to rotate.

[0008] Specifically, the large gear disk of the transmission gear meshes with the transmission component, which consists of a gear part and a locking part. The locking foot is obliquely hinged to the left and right sides of the locking part. A rotating slot is provided on one side of the rotating magnet. The transmission component is set in the rotating slot, and the locking foot is locked in the wave-shaped locking position on the outer side of the rotating slot.

[0009] Specifically, a locking element is provided on the outer side of the flashlight shell. The locking element moves up and down along the limiting plates on the left and right sides. An L-shaped clip is provided on the top of the locking element located inside the flashlight shell. A limiting groove is provided at the end of the arc-shaped push rod. The L-shaped clip is inserted into the limiting groove.

[0010] Specifically, the electromagnetic power generation device consists of a rotating magnet, a copper coil, a conductive sheet assembly, and a fixed base. The copper coil is electrically connected to the battery pack through the conductive sheet assembly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 3 A solar-powered hand-cranked mountaineering flashlight mainly includes: a light assembly, a battery pack, a flashlight shell, a solar panel, a hand-crank button, and an electromagnetic generator. The light assembly is installed at the front end of the flashlight shell. The battery pack is electrically connected to the light assembly, the electromagnetic generator, and the solar panel. The solar panel is fixed to the outer surface of the flashlight shell. The hand-crank button is located on one side of the flashlight shell and drives the rotating magnet of the electromagnetic generator to rotate via a transmission gear. The hand-crank button drives the rotating magnet of the electromagnetic generator to rotate rapidly, which, in conjunction with the copper coils on both sides, cuts the magnetic field lines, thereby supplying power to the light assembly. Solar energy can be used for energy storage if needed.

[0019] In the above-described design, the hand-cranked button extends into the flashlight housing at both its upper and lower ends. The hand-cranked button has a cylindrical sleeve, which is mounted inside the flashlight housing via a pivot. Torsion springs are fitted around both sides of the cylindrical sleeve. One end of the torsion spring abuts against a fixed rod inside the flashlight housing, and the other end abuts against a horizontal bar extending from the hand-cranked button into the flashlight housing. The bottom of the hand-cranked button is an arc-shaped push rod with teeth on one side. These teeth mesh with a transmission gear, causing the arc-shaped push rod to rotate. A locking mechanism is located on the outer side of the flashlight housing, moving up and down along the limiting plates on both sides. An L-shaped latch is located at the top of the locking mechanism inside the flashlight housing, and a limiting groove is located at the end of the arc-shaped push rod, into which the L-shaped latch is inserted.

[0020] When the hand-crank button is pressed inward, the torsion spring uses its own torque to push the button outward, quickly resetting it. Users can repeatedly press the hand-crank button, and in conjunction with the gear set, make the rotating magnet rotate rapidly in the same direction. When not in use, the locking mechanism can be used to lock the limiting groove at the end of the arc-shaped push rod, keeping the hand-crank button closed. When manual charging is needed, pushing the locking mechanism releases the hand-crank button, causing the torsion spring to unfold outward.

[0021] In the above scheme, the large gear disk of the transmission gear meshes with the transmission component, which consists of a gear section and a locking section. The locking feet are obliquely hinged to the left and right sides of the locking section. A rotating groove is provided on one side of the rotating magnet, and the transmission component is placed in the rotating groove. The locking feet are secured in the wave-shaped locking positions around the rotating groove. The electromagnetic generator consists of a rotating magnet, copper coils, conductive sheet groups, and a fixed base. The copper coils are electrically connected to the battery pack through the conductive sheet groups. Two copper coils are located on both sides of the rotating magnet, sandwiched between two conductive sheet groups. The conductive sheet groups are mounted on the fixed base. The rotating magnet is mounted on the fixed base via a central rotating shaft. The fixed base is bolted to the inner side of the outer casing, and the bolts are secured in three positions on the fixed base using washers.

[0022] Users can repeatedly press the hand crank button to charge the battery pack. During its movement, the curved push rod of the hand crank button drives a transmission gear to rotate rapidly via teeth on one side. The large gear disc on one side of the transmission gear also drives the transmission component to rotate via gear transmission. When the transmission component rotates in one direction, the locking feet on both sides of the transmission component engage with the wave-shaped locking positions of the rotating slot, thereby driving the entire rotating magnet to rotate rapidly. The copper coil cuts the magnetic field lines, generating electricity which is stored in the battery pack for use by the light assembly. When there is sunlight, electricity can be generated through a solar panel to power the light assembly as well.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
