Patent Application
20150193022
This application claims priority to Chinese Patent Application No. 201410001625.X filed on Jan. 3, 2014, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to wireless mouses, and particularly to a wireless mouse capable of self charging.
An existing wireless mouse usually gets power from dry cell battery or rechargeable battery. Those batteries need to be replaced or charged frequently due to small capacity.
Implementations of the present disclosure will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
In the illustrated embodiment, the generator 42 is coupled to the circuit board 50 via cables 60, and is configured to output electrical energy to the circuit board 50 to power the wireless mouse 100. In other embodiments, the generator 42 outputs electrical energy to an electrical energy storage device (not shown) for storage.
The rotating member 411 and the drive wheel 413 are coupled to the connection rod 412 and are able to rotate around the connection rod 412. In the illustrated embodiment, the connection rod 412 defines on an outside surface thereof a ratchet portion 4121. including a number of gears. The transmission device 41 further includes a stopper block 415 fixed on the rotating member 411 with a free end portion fitting one of the gears of the ratchet portion 4121.
The drive wheel 413 includes a main body 4131 and a hollow connection shaft 4132 extending from one end portion of the main body 4131. The transmission device 41 further includes an elastic member 416 received in the hollow connection shaft 4132 and wrapped around an outside surface of the connection rod 412. The elastic member 416 has one end portion fixed to the connection rod 412 and another end portion fixed to the hollow connection shaft 4132 of the drive wheel 413.
The slave wheel 414 is assembled on a rotating shaft 421 of the generator 42, and engaged with the drive wheel 413 via gears.
In use, when the rotating member 411 is driven to rotate, the connection rod 412 is rotated unidirectional by the engagement of the stopper block 415 and the gear of the ratchet portion 4121, the elastic member 416 is thus deformed to rotate the drive wheel 413, causing the slave wheel 414 is rotated by the engagement of the drive wheel 413 and the slave wheel 414. Thereby causing the rotating shaft 421 of the generator 42 to rotate and generate electrical energy to power the wireless mouse 100.
In the embodiment,
When the rotating member 411 is rotated along an opposite direction, such as counterclockwise, the stopper block 415 rotates with the rotating member 411 and goes out from the one gear and fits into another gear of the ratchet portion 4121 counterclockwise. At this time, the connection rod 412 does not rotate with the rotating member 411 counterclockwise, and the drive wheel 413, the slave wheel 414, and the rotating shaft 421 will not rotate due to the elastic member 416 remaining in a natural shape.
In the illustrated embodiment, each rotating member 411 of the first generation device 401 and the second generation device 402 includes a hollow sleeve 4111 and a pendulum 4112 extending from the hollow sleeve 4111. The rotating member 411 is assembled on the ratchet portion 4121 of the connection rod 412 through the hollow sleeve 4111, and the pendulum 4112 is driven to swing back and forth, that is to swing along a clockwise direction and a counterclockwise direction, under gravity when the wireless mouse 100 moves.
In one embodiment, the connection rod 412 of the first generation device 401 and the second generation device 402 are substantially perpendicular to each other, making the swing directions of the pendulum 4112 of the first generation device 401 and the second generation device 402 substantially perpendicular to each other, such that, when the wireless mouse 100 moves, at least one of the first generation device 401 and the second generation device 402 can collect mechanical energy.
In one embodiment, the connection rod 412 of the first generation device 401 and the second generation device 402 are respectively assembled along a length and a width of the body 20 of the wireless mouse 100.
In the illustrated embodiment, the rotating member 411′ of the third generation device 403 is fixed to a roller shaft 31 of the wireless mouse 100. When the scroll wheel 30 is scrolled forward or backward, the rotating member 411′ is rotated by the roller shaft 31 along a clockwise direction or a counterclockwise direction.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in particular the matters of shape, size, and arrangement of parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
