Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purposes, the following detailed description of the embodiments of the present invention is provided with the accompanying drawings and the preferred embodiments.
Referring to fig. 1, an embodiment of the present invention provides a hand-feeling switching mechanism for an optical encoder, especially for a mouse encoder, including:
the grating disc 1 is provided with a plurality of tooth positions 11 on the outer side edge, and specifically, the tooth positions 11 are uniformly distributed on the periphery of the grating disc 1; when the roller on the mouse is manually rolled, the grating disk 1 rotates along with the rolling;
a hand-sensing switch assembly 2 comprises a switch member 21 and an elastic lever structure 22 located between the grating disk 1 and the switch member 21, wherein one end of the elastic lever structure 22 is connected with the switch member 21, and the other end extends to the outside of the tooth position 11. In combination with the lever principle, the switching member 21 acts on one end of the elastic lever structure 22, so as to switch the other end of the elastic lever structure 22 between two states of contacting the tooth position 11 and leaving the tooth position 11. When the other end of the elastic lever structure 22 is contacted with the tooth positions 11, a roller on the mouse is manually rolled, the grating disk 1 coaxial with the roller rotates, the tooth positions 11 of the grating disk 1 act on the other end of the elastic lever structure 22, and the other end of the elastic lever structure 22 moves among the tooth positions 11 by combining the elastic characteristic of the elastic lever structure 22, so that hand feeling is generated; on the contrary, when the other end of the elastic lever structure 22 is driven to separate from the tooth position 11, the mouse has no hand feeling when being rolled.
Specifically, as shown in fig. 2, the elastic lever structure 22 mainly comprises a fixed rotating shaft 221 and a torsion spring 222 sleeved on the periphery of the fixed rotating shaft 221, wherein the torsion spring 222 mainly comprises a torsion spring body 2221, a connecting rod 2222 connected to one end of the torsion spring body 2221, and an acting rod 2223 connected to the other end of the torsion spring body 2221, the torsion spring body 2221 is sleeved on the periphery of the fixed rotating shaft 221, the connecting rod 2222 is connected to the switching member 21, and the acting rod 2223 extends to the outside of the tooth position 11. The fixed shaft 221 serves as a fulcrum of the elastic lever structure 22, so that the torsion spring body 2221 of the torsion spring 222 can rotate around the fixed shaft 221, and accordingly, the connecting rod 2222 and the acting rod 2223 can swing up and down. Specifically, when the switching member 21 acts on the connecting rod 2222 to swing the connecting rod 2222 downward, the acting rod 2223 correspondingly swings upward, so as to approach and contact the teeth 11 on the periphery of the grating disk 1, thereby achieving the purpose of having a hand feeling; when the switch 21 acts on the connecting rod 2222 to swing the connecting rod 2222 upward, the acting rod 2223 correspondingly swings downward, so as to leave the tooth positions 11 on the periphery of the grating disk 1, thereby achieving the purpose of no hand feeling.
Specifically, the connecting rod 2222 and the acting rod 2223 are L-shaped, so that the end of the connecting rod 2222 can be connected to the switching member 21, and the acting rod 2223 can contact the tooth position 11 when swinging up.
As to the specific structure of the switching element 21, as shown in fig. 1 and fig. 2, the switching element 21 is a toggle element, and the toggle element mainly comprises a toggle seat 211 and a toggle portion 212 disposed on the toggle seat 211, wherein an inclined toggle slot 2111 is formed on a side edge of the toggle seat 211, and an end portion of the connecting rod 2222 is movably inserted into the inclined toggle slot 2111. When the hand feeling and the hand feeling are not needed to be switched, the toggle part 212 is only needed to be toggled. When the toggle part 212 is toggled and the toggle seat 211 is moved, the end of the connecting rod 2222 slides in the inclined toggle slot 2111 under the guiding action of the inclined toggle slot 2111. Since the inclined toggle slot 2111 is inclined, when the toggle seat 211 moves in one direction to cause the end of the connecting rod 2222 to slide to the lowest position of the inclined toggle slot 2111, as shown in fig. 1 and 2, the connecting rod 2222 swings down, and accordingly, the action rod 2223 swings up. When the toggle seat 211 is moved in the opposite direction to slide the end of the connecting rod 2222 to the highest position of the inclined toggle slot 2111, as shown in fig. 5, the connecting rod 2222 swings up, and correspondingly, the action rod 2223 swings down. Therefore, under the guiding action of the inclined toggle slot 2111, the connecting rod 2222 can perform the swinging up and down actions, and the action rod 2223 performs the swinging action in the opposite direction to the connecting rod 2222 in combination with the lever principle. When the action rod 2223 swings up, it can contact the tooth position 11, and swings down, it moves away from the tooth position 11, so that the action rod 2223 is switched between two states of contacting the tooth position 11 and separating from the tooth position 11, and switching between the hand feeling and the hand feeling is realized.
For the installation of the switching element 21 and the elastic lever structure 22, the hand feeling switching assembly 2 of this embodiment further includes a housing 23, and a movable cavity 231 and a sliding cavity 232 are disposed in the housing 23, wherein the torsion spring 222 is disposed in the movable cavity 231, and the fixed rotating shaft 221 is fixed on the inner wall of the movable cavity 231; the toggle seat 211 is slidably disposed in the sliding cavity 232, and a toggle opening 233 for the toggle portion 212 to pass through is disposed on the housing 23, and when the switching operation is performed, the toggle portion 212 is toggled left and right along the toggle opening 233, as shown in fig. 3. Through the shell 23 with the movable cavity 231 and the sliding cavity 232, a space can be provided for the swinging action of the torsion spring 222 and the sliding action of the toggle seat 211, and the actions can be limited, so that the phenomena of displacement and the like are prevented, and the stability and the accuracy of the whole action process are improved.
In order to more conveniently toggle the toggle seat 211, the embodiment is implemented by using a gear design structure, specifically, as shown in fig. 4, a metal elastic sheet 3 is arranged on the inner wall of the sliding cavity 232, and the metal elastic sheet 3 is provided with a bending protrusion 31; at least two toggle grooves 2112 matched with the bent protruding portion 31 are formed on one side edge of the toggle seat 211 close to the metal elastic sheet 3, and the number of the toggle grooves 2112 is two in this embodiment. When stirring portion 212, the bending protruding portion 31 on the metal shrapnel 3 moves and switches between two stirring grooves 2112 of the stirring seat 211, so that not only can the stirring action be better and more conveniently controlled, the stirring seat 211 is prevented from moving in a disorderly manner, but also more hand feeling is brought during stirring, two stirring gears are obtained, one gear is a gear with hand feeling, and the other gear is a gear without hand feeling.
The hand-feeling switching mechanism provided by the embodiment is particularly suitable for an optical encoder and is applied to a mouse. Through operating the hand feeling switching mechanism, two experiences of hand feeling and no hand feeling can be obtained when the roller on the mouse is rolled artificially. The specific structure and principle of the optical encoder are the same as those of the conventional optical encoder in the field. The grating disk 1 in this embodiment is a grating disk in an optical encoder conventional in the art.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by using the same or similar technical features as the above-described embodiments of the present invention are within the protection scope of the present invention.
