Description

Technical Field

[0001] This invention belongs to the field of watch winder technology, and particularly relates to an adjustable watch winder and its usage method. Background Technology

[0002] When people sleep at night, the movement of an automatic watch (or mainspring watch) cannot store enough energy, causing the hands to stop moving. Examples include watches with three common automatic winding mechanisms: self-weighted central rotor, self-weighted peripheral rotor, and self-weighted eccentric rotor. To solve the problem of these three types of watches stopping, watch winders were invented. Electromagnetically driven watch winders, commonly found on the market, fix the watch under a oscillating frame (in a stationary state, the center of the watch dial is located below the axis of the oscillating frame, i.e., the end closest to the horizontal ground). When the watch winder swings, the watch also swings.

[0003] However, this type of watch winder has a major drawback. When the oscillating frame is in motion, the watch dial undergoes a variable-speed circular motion around the axis of the oscillating frame, and the rotation center and center of gravity of the watch rotor also synchronously undergo variable-speed circular motion around the axis of the oscillating frame. When the acceleration of the oscillating frame is the same as the acceleration of the rotor, the rotor is stationary relative to the dial, meaning it cannot wind the watch. When the acceleration of the oscillating frame and the rotor are not significantly different, the rotor moves relative to the dial, but the amplitude of its oscillation is very small, resulting in poor winding efficiency, and the amplitude of the oscillation cannot be adjusted. Summary of the Invention

[0004] This invention provides an adjustable watch winder, which aims to solve the problems of poor winding efficiency and inability to adjust the swing amplitude of current electromagnetically driven watch winders.

[0022] Step 3: Adjust the position of the upper counterweight on the resistance arm and the position of the lower counterweight on the power arm to balance the magnitude of the swing force;

[0023] Step 4: Activate the electromagnetic module to generate a repulsive force between the pendulum frame and the electromagnetic module, causing the pendulum to move and wind the watch placed in the watch holder.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This invention provides an adjustable watch winder, such as... Figures 1-7 As shown, the adjustable watch winder includes:

[0038] Base 300;

[0039] A swing frame 100 rotatably connected to a support column 120 mounted on a base 300;

[0040] Support modules are respectively disposed on both sides of the swing frame 100 and fixedly connected to the rotating shaft 110 on the support column 120;

[0041] The swing frame 100 is movably equipped with an upper counterweight 410 and a lower counterweight 420; under the repulsive force generated by the permanent magnet 430 at the bottom of the swing frame 100 and the electromagnetic module 320 on the base, the swing frame 100 rotates around the rotation axis 110 at the top of the support column 120.

[0042] In this embodiment, after the electromagnetic module 320 on the base is energized, the electromagnetic module 320 generates a magnetic pole opposite to the direction of the permanent magnet 430 facing the electromagnetic module 320. The swing frame 100 in its natural vertical state will generate a thrust due to the repulsive force between the permanent magnet 430 and the electromagnetic module 320, causing the swing frame 100 to rotate around the rotation axis 110. When the swing frame 100 deflects to a certain height, the repulsive force gradually decreases, and the swing frame 100 returns to the vertical state under the action of the upper counterweight 410 and the lower counterweight 420 on the swing frame 100. Due to the repulsive force of the electromagnetic module 320, the swing frame 100 will swing again, and the swing frame 100 will perform a back-and-forth pendulum motion.

[0043] In this embodiment, the support module includes a left support 210, a right support 220, a left sliding plate 230 and a right sliding plate 240 fixed to the left and right ends of the rotation shaft 110. The left support 210 is fixedly connected to the left sliding plate 230, and the right support 220 is fixedly connected to the right sliding plate 240. The rotation shaft 110 rotates synchronously with the swing frame 100, and the left support 210 and the right support 220, which are respectively fixedly installed on the left sliding plate 230 and the right sliding plate 240, rotate synchronously accordingly.

[0044] In a further preferred embodiment of the present invention, the pivot of the swing frame 100 is used as the fulcrum. One end of the swing frame 100 with permanent magnet 430 is the power arm 104, and the other end is the resistance arm 103. The upper counterweight 410 is slidably connected to the resistance arm 103 of the swing frame 100, and the lower counterweight 420 is slidably connected to the power arm 104 of the swing frame 100. The upper counterweight 410 and the lower counterweight 420 are provided with limiting holes. The limiting bolts 450 provided in the limiting holes cooperate with the limiting teeth provided on the power arm 104 and the resistance arm 103 to adjust the position of the upper counterweight 410 and the lower counterweight 420 on the swing frame 100.

[0045] In this embodiment, the limiting bolt 450 and the limiting tooth are existing technologies. The limiting tooth has a wave-shaped structure and is arranged on the side wall of the power arm 104 and the resistance arm 103. The limiting bolt 450 passes through the limiting holes provided on the upper counterweight 410 and the lower counterweight 420 and contacts the limiting tooth. With the engagement of the limiting bolt 450 and the limiting hole, the limiting tooth is locked and limited. According to the structural characteristics of the limiting tooth, the user can freely select the fixed position of the limiting bolt 450 and the limiting tooth as needed, thereby achieving the purpose of adjusting the position of the upper counterweight 410 and the lower counterweight 420 on the swing frame 100.

[0046] In this embodiment, when the torque of the power arm 104 is much greater than the torque of the resistance arm 103, the swing amplitude of the swing frame 100 is small; when the torque of the power arm 104 is close to the torque of the resistance arm 103, the two ends of the swing frame 100, the power arm 104 and the resistance arm 103 are nearly balanced. Under the thrust of the base electromagnet, the swing amplitude of the swing frame 100 is the largest. The swing amplitude of the watch winder is controlled by adjusting the position of the upper counterweight and the lower upper counterweight relative to the swing frame, thereby controlling the winding time.

[0047] In a further preferred embodiment of the present invention, the front end and the rear end of the swing frame 100 are respectively provided with a balance frame structure, the balance frame structure including a front balance frame 101 located at the front end of the support column 120 and a rear balance frame 102 located at the rear end of the support column 120.

[0048] In this embodiment, the balance frame structure is existing technology, which can help the swing frame 100 quickly achieve balance;

[0049] In a preferred embodiment of this invention, the right bracket 220 includes a tray 221, a watch bracket 222, and a buckle 223; a groove on the back of the tray 221 is slidably connected to the right sliding plate 240, the watch bracket 222 is mounted on the tray 221, and the buckle 223 is located on the top of the watch bracket 222.

[0050] In this embodiment, the watch holder 222 is the prior art. The snap 223 with the opening and closing structure can help the watch holder 222 limit the watch placed in the watch holder 222, which improves the convenience of placing the watch and prevents the watch from slipping out of the watch holder 222 during movement.

[0051] In a preferred embodiment of this invention, the swing frame 100 is provided with a corrective permanent magnet 440 at the four corners of its bottom; the base 300 is provided with an auxiliary permanent magnet 310 at its top, and the magnetic poles of the corrective permanent magnet 440 on its downward plane are opposite in direction to the magnetic poles of the auxiliary permanent magnet 310 on its upward plane.

[0052] When the swing frame 100 has a large swing amplitude, the corrective permanent magnet 440 on the swing frame 100 will be repulsed when it moves to the vicinity of the auxiliary permanent magnet 310 on the base 300. This force will cause the swing frame 100 to swing back quickly, which can increase the swing frequency.

[0053] In a preferred embodiment of this invention, the tray 221 is provided with a slide rail 2211 on the plane near the right sliding plate 240, and the slide rail 2211 is provided with an embedded nut 2212. The slide rail 2211 is slidably assembled with the right sliding plate 240. The embedded nut 2212 on the slide rail 2211 is in contact with the right sliding plate 240 to achieve the function of fastening and locking between the tray 221 and the right sliding plate 240.

[0054] In a preferred embodiment of this invention, the outer side of the tray 221 is provided with a column, and the column is provided with a positioning hole 2213;

[0055] The position of the tray 221 and the right sliding plate 240 is fixed by adjusting the screws inside the inlaid nut 2212. When the tray 221 is installed at the bottom of the right sliding plate 240, the center of the positioning hole 2213 is aligned with the axis of the swing frame 100 and is on the same horizontal line. The watch is placed in the watch holder 222 so that the center of the dial is on the same horizontal line as the axis of the swing frame, thereby achieving the maximum winding efficiency.

[0056] In this embodiment, after the user places the watch into the watch holder 222, they can move the watch up and down. Using the small hole on the adjacent column as a reference, the center of the watch dial can be aligned with the axis of the oscillating frame 100 and placed on the same horizontal line. When the center of the dial of the self-weighted central oscillating weight and the self-weighted outer oscillating weight watch is aligned with the axis of the oscillating frame 100, the dial will move together with the oscillating frame. This can be seen as the dial rotating back and forth around the axis of the oscillating frame. The plane of the dial is perpendicular to the horizontal ground and also perpendicular to the axis of the oscillating frame. The oscillating weight, due to gravity, always maintains a downward posture, but with the dial as a reference, the oscillating weight swings significantly, thus greatly improving the winding efficiency of the oscillating weight. This method greatly improves the winding efficiency of the watch winder for watches with self-weighted central oscillating weights and self-weighted outer oscillating weights.

[0057] This invention provides a method for using the adjustable watch winder as described above, including:

[0058] Step 1: Place the watch in the watch holder 222 and adjust the center of the dial to align with the positioning hole 2213 so that they are on the same central axis;

[0059] Step 2: Adjust the positioning hole 2213 according to the watch model. For watches with a self-weighted center rotor or a self-weighted outer edge rotor, adjust the screw inside the inlaid nut 2212 to adjust the positioning hole 2213 to the bottom of the right sliding plate 240 so that the center of the dial is on the same horizontal line as the axis of the rotor. For watches with a self-weighted eccentric rotor, adjust the positioning hole 2213 to the middle of the right sliding plate 240 so that the center of the dial is above the horizontal line of the axis of the rotor.

[0060] Step 3: Adjust the position of the upper counterweight 410 on the resistance arm 103 and the position of the lower counterweight 420 on the power arm 104 to balance the magnitude of the swing force;

[0061] Step 4: Activate the electromagnetic module 320 to generate a repulsive force between the swing frame 100 and the electromagnetic module 320, causing the pendulum to move and wind the watch placed in the watch holder 222.

[0062] Step 5: After winding is complete, turn off the electromagnetic module 320, stop the movement of the swing frame 100, and remove the watch placed in the watch holder 222 from the watch holder 222 to complete the entire winding process.

[0063] In this embodiment, after the user places the watch into the watch holder 222, they move the watch up and down. Using the small hole on the adjacent column as a reference, they adjust the position of the right bracket 220 or the left bracket 210 on the sliding plate assembly so that the center of the dial is aligned with the axis of the swing frame 100 and on the same horizontal line, or so that the center of the dial is above the axis of the swing frame 100. This allows for winding various watch models, maximizing the swing amplitude of the self-weight center oscillating rotor, self-weight outer edge oscillating rotor, or self-weight eccentric oscillating rotor watches, and significantly improving winding efficiency.
