Description

Technical field

[0001] The utility model relates to the technical field of generators, in particular to a hand-pulled wire generator. [Background Technology]

[0002] With the increasing use of electronic products in all aspects of our lives, the need for emergency charging often arises, especially when we're out and about. Traditional portable generators are hand-cranked, allowing them to charge mobile power banks or electronic devices. However, hand-cranked generators require manual rotation, which can cause hand pain and make it difficult to crank them patiently for a long time. Furthermore, their long crank handles make them less elegant and aesthetically pleasing.

[0003] In view of this, it is necessary to provide a hand-pulled wire generator to overcome the above-mentioned defects. [Utility Model Content]

[0004] The purpose of the utility model is to provide a hand-pulled wire generator, aiming to improve the problem that hand-cranked generators are prone to hand soreness and have a less concise and aesthetically pleasing structure.

[0005] In order to achieve the above object, the utility model provides a hand-pulled wire generator, comprising:

[0006] A base substrate, wherein the base substrate is provided with a first rotating shaft and a second rotating shaft;

[0007] A first gear, the first gear is connected to the first rotating shaft and is coaxially provided with a fixing cylinder;

[0008] a mainspring, the mainspring being housed in the fixed cylinder and having one end connected to the first rotating shaft and the other end connected to the fixed cylinder;

[0009] a rope, the rope being wound around the outside of the fixing cylinder and having one end connected to the fixing cylinder;

[0010] A rotating cylinder, wherein one side of the rotating cylinder is provided with a receiving groove and the other side is provided with a driving groove along the axial direction; a circle of ratchet teeth is provided on the side wall of the driving groove; and a magnet rotor is provided on the side wall of the receiving groove;

[0012] Two pawls, the two pawls being rotatably disposed on opposite sides of the rotating block and being engaged with the ratchet teeth;

[0013] a coil stator, the coil stator being wrapped around the second rotating shaft and extending into the receiving groove;

[0014] an output port, the output port being electrically connected to the coil stator;

[0015] When the rope is pulled, the first gear is driven to rotate, thereby driving the second gear to rotate and tightening the mainspring; when the rope is loosened, the mainspring is reset, so that the rope is rewound around the fixed cylinder; the second gear is used to drive the rotating cylinder to rotate unidirectionally around the second rotating axis, so that the magnet rotor cooperates with the coil stator, thereby causing the output port to output current to the outside.

[0016] In a preferred embodiment, the first rotating shaft is provided with a slot, and one end of the mainspring located on the inner ring is engaged in the slot.

[0017] In a preferred embodiment, two circles of spaced-apart limiting convex rings are provided on the outer side of the fixing cylinder, and the rope is wound around a portion of the fixing cylinder located between the two spaced-apart limiting convex rings.

[0018] In a preferred embodiment, the radius of the first gear is greater than the radius of the second gear.

[0022] The hand-pulled wire generator provided by the present invention drives the first gear to rotate when the rope is pulled, thereby driving the second gear to rotate and tightening the mainspring. During this process, the rotating drum is driven to rotate unidirectionally around the second rotating shaft, so that the magnet rotor and the coil stator cooperate, thereby causing the output port to output current outward in succession. Furthermore, when the rope is loosened, the mainspring is reset, so that the rope is rewound around the fixed drum, allowing the next pulling action to be performed. The present invention replaces the hand-cranking action of the hand-cranked generator with a hand-pulling action, which is more flexible and relatively less prone to soreness. In addition, the hand-cranking handle is eliminated, making the overall structure more simple and beautiful.

It should be understood that the specific embodiments described in this specification are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0030] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0031] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] In an embodiment of the present invention, a hand-pulled wire generator 100 is provided for emergency charging of mobile power supplies or electronic products.

[0033] like Figures 1-4 As shown, the hand-pulled wire generator 100 includes: a base plate 10, a first gear 20, a spring 30, a rope 40, a rotating drum 50, a rotating block 60, two pawls 70, a coil stator (not shown in the figure) and an output port 80.

[0034] Specifically, the base substrate 10 is provided with a first rotating shaft 11 and a second rotating shaft 12. A plurality of bearings are sleeved and fixed on the first rotating shaft 11 and the second rotating shaft 12.

[0035] The first gear 20 is connected to the first rotating shaft 11 and is coaxially mounted with a fixed cylinder 21. In this embodiment, the fixed cylinder 21 is hollow and cylindrical and is coaxially mounted on the side of the first gear 20 closest to the base substrate 10. Specifically, the fixed cylinder 21 is also mounted on the bearing of the first rotating shaft 11. The first gear 20 and the fixed cylinder 21 rotate synchronously.

[0036] Combine Figure 3 As shown, the mainspring 30 is housed within the fixed barrel 21, meaning that the fixed barrel 21 can also accommodate the mainspring 30 in an untightened state. One end of the mainspring 30 is connected to the first rotating shaft 11, and the other end is connected to the fixed barrel 21. The first rotating shaft 11 defines a slot (not shown), into which one end of the mainspring 30, located on the inner ring, engages. When the fixed barrel 21 rotates under an external force, the mainspring 30 is tightened. When the external force applied to the fixed barrel 21 is removed, the tightened mainspring 30 releases its elastic potential energy, causing the fixed barrel 21 to rotate in the opposite direction.

[0037] A rope 40 is wound around the outside of the fixed cylinder 21, with one end connected to the fixed cylinder 21. The fixed cylinder 21 is provided with two spaced-apart retaining rings 22. The rope 40 is wound around the fixed cylinder 21 between the two retaining rings 22 to prevent the rope 40 from slipping off the ends of the fixed cylinder 21. In this embodiment, the rope 40 may be a steel wire rope. When the rope 40 is pulled, it rotates the fixed cylinder 21, which in turn rotates the first gear 20.

[0038] Combine Figure 4 As shown, the rotating cylinder 50 is cylindrical, with a receiving groove (not shown) on one side along the axial direction and a driving groove 501 on the other side. The sidewall of the driving groove 501 is provided with a circle of ratchet teeth 51. The sidewall of the receiving groove is provided with a magnet rotor (not shown). The magnet rotor can be a circle of permanent magnets.

[0039] The center of the rotating block 60 is sleeved and fixed on the second rotating shaft 12. Two pawls 70 are rotatably mounted on opposite sides of the rotating block 60 and engage with the ratchet teeth 51. The rotating block 60 is diamond-shaped and has connecting holes on opposite sides. One end of the pawl 70 is rotatably connected to the corresponding connecting hole via a third rotating shaft 71, and the end of the pawl 70 away from the connecting hole engages with the ratchet teeth 51. Therefore, through the cooperation of the pawl 70 and the ratchet teeth 51, the bidirectional rotation of the rotating block 60 is converted into unidirectional rotation of the rotating cylinder 50. It should be noted that the principle of achieving unidirectional rotation between the pawl 70 and the ratchet teeth 51 can be referred to in the prior art and will not be repeated here.

[0040] The rotating block 60 is equipped with a second gear 61. Both the rotating block 60 and the second gear 61 are mounted on bearings on the second rotating shaft 12. The second gear 61 meshes with the first gear 20. Rotation of the first gear 20 drives the second gear 61, which in turn drives the rotating block 60. Furthermore, the radius of the first gear 20 is greater than that of the second gear 61. This means that the gear ratio of the first gear 20 to the second gear 61 is greater than one, thereby improving the rotational efficiency of the rotating block 60 and, ultimately, the power generation efficiency.

[0041] In this embodiment of the present invention, a coil stator (not shown) surrounds the second rotating shaft 12 and extends into the receiving slot, where it engages the magnet rotor. An output port 80 is electrically connected to the coil stator. When the rotating cylinder 50 rotates, it drives the magnet rotor, causing the coil stator to cut through the magnet rotor's magnetic flux lines, generating an induced current within the coil stator, which is then output through the output port 80.

[0042] Furthermore, the hand-pulled wire generator 100 also includes a voltage-scaling and rectifying module (not shown). The voltage-scaling and rectifying module is electrically connected to the output port 80 to regulate and rectify the output current of the output port 80, thereby making the output current more stable. It should be noted that the principle and specific structure of the voltage-scaling and rectifying module can be referred to in the prior art and are not limited by the present invention.

[0043] Furthermore, the hand-pulled wire generator 100 also includes an outer cover 90. The outer cover 90 is connected to the base substrate 10 to form a receiving chamber (not shown in the figure). The first gear 20, the fixed cylinder 21, the second gear 61, the rotating cylinder 50 and other related parts are all located in the receiving chamber to prevent external debris from affecting power generation. The outer cover 90 also has a first through hole (not shown in the figure) for the output port 80 to pass through and a second through hole (not shown in the figure) for the rope 40 to pass through.

[0044] In the embodiment of the present invention, when the rope 40 is pulled, the fixed cylinder 21 and the first gear 20 rotate (e.g., clockwise), which in turn drives the second gear 61 and the rotating block 60 to rotate (counterclockwise), tightening the mainspring 30. During this process, the pawl 70 drives the rotating cylinder 50 to rotate counterclockwise, allowing the magnet rotor to mate with the coil stator, thereby allowing the output port 80 to output current. When the rope 40 is released, the mainspring 30 resets, driving the fixed cylinder 21 and the first gear 20 to rotate counterclockwise, causing the rope 40 to rewind around the fixed cylinder 21. The second gear 61 and the rotating block 60 rotate clockwise. At this time, the pawl 70 does not drive the rotating cylinder 50 to rotate clockwise. In other words, the second gear 61 is used to drive the rotating cylinder 50 to rotate unidirectionally about the second rotating shaft 12, ultimately achieving unidirectional rotation of the rotating cylinder 50 and enabling the continuous output of current.

[0045] In summary, the hand-pulled wire generator 100 provided by the present invention drives the first gear 20 to rotate when the rope 40 is pulled, so as to drive the second gear 61 to rotate and tighten the mainspring 30. In this process, the rotating cylinder 50 is driven to rotate unidirectionally around the second rotating shaft 12 so that the magnet rotor cooperates with the coil stator, thereby causing the output port 80 to output current outward in succession. Furthermore, when the rope 40 is loosened, the mainspring 30 is reset so that the rope 40 is rewound on the fixed cylinder 21, so that the next pulling action can be performed. The present invention replaces the hand-cranking action of the hand-cranked generator with a hand-pulling action, which is more flexible and relatively less prone to soreness. In addition, the hand-cranking handle is eliminated, making the overall structure more simple and beautiful.

[0046] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrated examples shown and described herein.
