Description

Electromagnetic meter shaker Technical Field

[0001] The utility model relates to the field of watch winders, in particular to an electromagnetic watch winder. Background Art

[0002] Automatically winding mechanical watches have a kinetic energy storage device built into them. This energy is converted into elastic potential energy by the watch's spring by the frequent arm swings that occur when the watch is worn. However, at night, when a person sleeps, the watch loses sufficient energy and the hands stop moving.

[0003] At present, all watch winders on the market are driven by motors, which drive the stand (or watch tray) on which the watch is placed to provide kinetic energy. This kinetic energy is then converted into elastic potential energy of the watch spring through the kinetic energy storage device inside the mechanical watch. Technical issues

[0004] However, motor drive has the following disadvantages: (1) The motor makes noise when it rotates. (2) If you want to speed up the winding process, you need to increase the motor speed. The faster the motor speed, the louder the noise. (3) The carbon brushes in the motor are easily worn, resulting in a short product lifespan, many of which only last about a year. Brushless motors are also very expensive and are not suitable for this type of product. (4) Motor-driven watch winders cannot simulate the movement of a person's hand. Technical Solutions

[0005] The utility model provides an electromagnetic meter shaker to solve at least one of the above technical problems.

[0006] To solve the above problems, as one aspect of the utility model, an electromagnetic meter shaker is provided, including: a base, a bracket, an electromagnet, a control circuit and a meter shaker mechanism, the bracket is arranged on the base, the meter shaker mechanism is pivotally mounted on the bracket, the meter shaker mechanism includes a meter holder, a swing arm, and a swing arm magnet connected in sequence from top to bottom, the electromagnet is arranged in a boss on the upper surface of the base and is located on the movement path of the swing arm magnet, and the control circuit is connected to the electromagnet.

[0007] Preferably, a counterweight is provided between the swing arm and the swing arm magnet.

[0008] Preferably, a pendulum box is provided outside the counterweight.

[0009] Preferably, the watch holder includes a middle frame and a telescopic frame, and the middle frame is connected to the telescopic frame through a built-in spring.

[0010] Preferably, the watch holder is connected to the swing arm via a support plate, the support plate is connected to the bracket via a bearing, and the watch holder is located above the bearing. Beneficial effects

[0011] The utility model can make the watch winder quieter, better simulate the hand movement posture, and improve the compatibility of the watch winder and the winding efficiency of the watch. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG1 schematically shows a structural diagram of the present utility model.

[0013] Reference numerals in the figure: 1, base; 2, table support; 3, bracket; 4, swing arm; 5, swing arm magnet; 6, telescopic frame; 7, support plate; 8, boss; 9, bearing; 10, pendulum box; 11, middle frame. Specific embodiments of the present invention

[0014] The following is a detailed description of the embodiments of the present invention. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0015] As one aspect of the present invention, an electromagnetic meter shaker is provided, comprising: a base 1, a bracket 3, an electromagnet, a control circuit and a meter shaker mechanism, wherein the bracket 3 is arranged on the base 1, and the meter shaker mechanism is pivotally mounted on the bracket 3. The meter shaker mechanism comprises a meter support 2, a swing arm 4, and a swing arm magnet 5 connected in sequence from top to bottom, the electromagnet is arranged in a boss 8 on the upper surface of the base 1 and is located on the movement path of the swing arm magnet 5, and the control circuit is connected to the electromagnet.

[0016] Preferably, the watch holder 2 is connected to the swing arm 4 through a support plate 7 , the support plate 7 is connected to the bracket 3 through a bearing 9 , and the watch holder 2 is located above the bearing 9 .

[0017] The polarity of the swing arm magnet 5 and the electromagnet is the same, and the control circuit and the electromagnet are placed inside the boss 8. The swing arm 4 is a detachable structure, which is fixed by hand screws, making it convenient for users to disassemble and reduce the volume of product packaging, which is more environmentally friendly.

[0018] The electromagnetic drive and bearing 9 design make the product structure simple and reliable. During the swing process, only slight wear of the bearing occurs, which greatly increases the service life. The bearing column on the support plate 7 is slotted to make the bearing column elastic and facilitate the installation and removal of the bearing.

[0019] Preferably, a counterweight is provided between the swing arm 4 and the swing arm magnet 5. Preferably, a pendulum box 10 is provided outside the counterweight.

[0020] Preferably, the watch holder 2 includes a middle frame 11 and a telescopic frame 6, wherein the middle frame 11 is connected to the telescopic frame 6 via an internal spring. The watch holder 2 is mounted above the rotation axis and fixed to the support plate 7 with screws. When the watch shaker is swung, it can simulate the movement of the arm and wrist when working on a desk. The elbow is supported by the desk (the elbow is fixed), and the wrist is raised and lowered upwards, i.e., the elbow serves as a fulcrum, and the wrist moves back and forth along an arc upwards.

[0021] In the above technical solution, the utility model adopts an electromagnetic drive method. When the swing arm magnet 5 on the swing arm 4 swings to the vicinity of the boss 8, the coil of the electromagnet inside the boss 8 starts to work and generate magnetic force under the control of the control circuit, which repels the swing arm magnet 5 on the swing arm 4 with the same pole to generate thrust, thereby pushing the swing arm 4 to swing continuously, so no motor drive is required and there is no noise.

[0022] By employing the above-mentioned technical solution, the present invention simulates the arm and wrist movements of people working at a desk. The elbow is supported by the desk (the elbow is fixed), and the wrist is raised and lowered upwards, creating a circular motion with the elbow as the fulcrum. Simply placing an automatic watch on the new watch winder and shaking it for a while automatically winds the watch. This simulated motion design improves the compatibility of the watch winder, making it compatible with a wider range of watch models.

[0023] The utility model can make the watch winder quieter, better simulate the hand movement posture, and improve the compatibility of the watch winder and the winding efficiency of the watch.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
