Referring to fig. 1 and 2, the present invention discloses a power switch 10 for implementing tactile feedback based on a torsion spring, including: switch base 100, trigger device 200, and tactile feedback device 300.
As shown in fig. 2, the triggering device 200 and the tactile feedback device 300 are mounted on the switch base 100, and the triggering device 200 is drivingly connected to the tactile feedback device 300.
Specifically, the triggering device 200 includes a rotating assembly 210 and a sliding assembly 220 (shown in fig. 3).
As shown in fig. 4, the rotating assembly 210 includes a rotating push rod 211, the rotating push rod 211 is rotatably provided on the switch base 100, and the rotating push rod 211 has a connecting sub-rod 212.
As shown in fig. 4, the sliding assembly 220 includes a sliding sleeve 221, the sliding sleeve 221 is movably sleeved on the rotary pushing rod 211, the rotary pushing rod 211 is provided with a pressing pushing nail 213, the sliding sleeve 221 is provided with an arc-shaped limiting guiding slot 222 engaged with the pressing pushing nail 213, the engagement of the arc-shaped limiting guiding slot 222 and the pressing pushing nail 213 realizes the driving connection between the sliding sleeve 221 and the rotary pushing rod 211, and the specific process will be explained below.
As shown in fig. 3 and 4, the tactile feedback device 300 includes a tactile feedback plate 310 and an energy storage elastic member 320, the tactile feedback plate 310 is fixedly sleeved on the sliding sleeve 221, the energy storage elastic member 320 connects the sliding sleeve 221 and the connecting sub-rod 212 of the rotating push rod 211, and the energy storage elastic member 320 is used for providing elastic force for the tactile feedback plate 310 and the sliding sleeve 221, on one hand, accumulating elastic potential energy for the movement of the tactile feedback plate 310, and on the other hand, restoring the tactile feedback plate 310 and the sliding sleeve 221.
As shown in fig. 3, the switch base 100 is provided with a holding block 110, the tactile feedback disc 310 is provided with a ring-shaped gear 311, and the gear 311 is held on or separated from the holding block 110. When the switch is adjusted, the cooperation of the power storage elastic member 320, the tactile feedback disc 310 and the holding block 110 can generate a vibration effect to bring clear tactile feedback to the operator, which will be described in detail below.
Preferably, in this embodiment, the power storage elastic member 320 is a torsion spring structure, and the holding block 110 is a cylinder structure.
The operation of the power switch 10 based on the torsion spring to realize the tactile feedback will be explained (please refer to fig. 5 and 6 together):
an operator provides torque for the rotary pushing rod 211 to make the rotary pushing rod 211 rotate, at this time, the connection auxiliary rod 212 and the pressing and holding pushing nail 213 rotate around the central axis of the rotary pushing rod 211, and the pressing and holding pushing nail 213 is pressed and held on the groove wall of the arc-shaped limiting guide groove 222. Since the tactile feedback disk 310 is fixedly connected to the sliding sleeve 221, and the gear 311 of the tactile feedback disk 310 and the holding block 110 are abutted against each other, the sliding sleeve 221 cannot rotate along with the pressing pushing pin 213, and the sliding sleeve 221 can only slide downward under the action of the pressing pushing pin 213. In this process, the relative position of the coupling sub-rod 212 and the sliding sleeve 221 is changed, and the power accumulating elastic member 320 coupled to the sliding sleeve 221 is deformed to continuously accumulate elastic potential energy, and at the same time, the tactile feedback plate 310 is gradually moved downward along with the sliding sleeve 221;
as the sliding sleeve 221 moves, the sliding sleeve 221 touches and presses the contact 400 (shown in fig. 5) provided below, thereby adjusting the connection relationship of the subsequent circuit. When the sliding sleeve 221 touches and presses the contact, the tactile feedback disc 310 just passes over the holding block 110, at this time, the gear teeth 311 are no longer held by the holding block 110, and the accumulated elastic potential energy is converted into the kinetic energy of the sliding sleeve 221 and the tactile feedback disc 310 by the energy accumulation elastic member 320, so as to drive the sliding sleeve 221 and the tactile feedback disc 310 to rotate. During the rotation process, due to the cooperation of the pressing pushing nail 213 and the arc-shaped limiting guiding slot 222, the sliding sleeve 221 and the tactile feedback disc 310 will move upwards, and the sliding sleeve 221 is far away from the contact. As the tactile feedback disk 310 ascends, the new gear 311 hits the catching block 110 and is held by the catching block 110, i.e. the sliding sleeve 221 and the tactile feedback disk 310 stop rotating and moving. In this process, the collision of the gear teeth 311 with the holding block 110 generates vibration, and transmits the vibration to the operator through the triggering device 200, thereby realizing tactile feedback.
It is emphasized that each time the sliding sleeve 221 presses the contact, the gear teeth 311 of the tactile feedback disc 310 collide with the holding block 110 once, i.e. each time the switch is triggered, a corresponding tactile feedback is obtained, so that the operator can obtain an accurate and highly exciting signal to determine that the switch is operated effectively. Further, the triggering device 200 and the tactile feedback device 300 of the present invention serve as an insulating medium between the circuit and the operator; meanwhile, the power switch 10 of the present invention, which implements tactile feedback based on the torsion spring, changes the pressing action of the conventional switch into a rotating action (by rotating the rotating push rod 211, the moving sleeve 221 is finally brought into contact with the contact in a pressing manner), and compared with the conventional pressing action, the pressing action is finally implemented by the rotating action, so that the possibility of accidental touch can be reduced. Thus, the power switch 10 of the present invention that implements tactile feedback based on a torsion spring also improves the safety factor of the switch.
In one embodiment, the tactile feedback disk 310 and the holding block 110 are made of metal. On one hand, when the gear teeth 311 of the tactile feedback disc 310 collide with the holding block 110, the generated vibration effect can be more obvious; on the other hand, the collision of the metal tactile feedback disc 310 with the holding block 110 will generate a crisp knocking sound, and also provide an audible feedback for the operator.
In one embodiment, the haptic feedback disk 310 is made of plastic. In this way, the plastic haptic feedback plate 310 can not only increase the dielectric constant of the haptic feedback device 300, but also reduce the overall weight of the switch.
As shown in fig. 2, in the present embodiment, the rotating assembly 210 further includes a rotating handle 214, the rotating handle 214 is disposed outside the switch base 100, and the rotating handle 214 is fixedly connected to the rotating pushing rod 211. In one embodiment, the turning handle 214 is further provided with an anti-slip groove 215, so that the operator can more conveniently adjust the rotation of the switch.
In one embodiment, the haptic feedback disk 310 is provided with a plurality of weight-reducing through holes 312 (as shown in fig. 3), wherein the plurality of weight-reducing through holes 312 are distributed in an annular array around the axis of the haptic feedback disk 310. Therefore, the weight of the whole switch can be reduced, and materials can be saved.
In summary, the power switch 10 of the present invention, which implements tactile feedback based on the torsion spring, can give effective tactile feedback to the operator during operation, and has functions of confirmation and reminding.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
