Description

Technical Field

[0001] This invention relates to the field of electronic watch technology, and in particular to a high-precision electronic watch. Background Technology

[0002] An electronic watch is a timekeeping instrument equipped with internal electronic components. It is powered by a battery and uses electronic circuits to display time and perform other functions. It is characterized by accurate timekeeping, diverse functions, and affordable price. An electronic watch is mainly composed of a case, dial, movement, hands, and crown.

[0003] The crown is typically used to adjust the time on a digital watch. To do this, the crown is usually pulled to one side, moving the stem connected to it. This allows a gear on the stem to engage with a gear inside the movement used for time adjustment. Rotating the crown then adjusts the time on the watch.

[0004] However, when electronic watches are used in environments with high humidity and high temperature, such as while taking a shower or in a sauna, the water vapor in the air is hot and the vapor molecules are small. This water vapor may seep into the movement inside the watch case through the gap between the crown and the watch case, thus affecting the normal use of the electronic watch. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a high-precision electronic watch, which aims to improve the problem in the prior art where the temperature of hot water steam is high and the steam molecules are small, which may seep into the movement inside the watch case through the gap between the crown and the watch case, thus affecting the normal use of the electronic watch.

[0037] In this invention, 1. The base plate is fixed to the bottom of the outer shell so that the partition is inserted between the second turntable and the first turntable. At the same time, the side wall of the partition is in close contact with the inner side wall of the outer shell, dividing the outer shell into two cavities. At this time, the water vapor that enters the inside of the watch case through the gap between the rotating shaft and the watch case will be trapped inside the watch case, and the partition will absorb it, thereby preventing water vapor from entering the watch case, movement and electronic timer, and thus corroding the gears inside the movement and electronic timer.

[0038] 2. The rotation of the rotating shaft, the cooperation of the rotating disc, the magnet, and the magnet causes the rotating disc to rotate, which in turn rotates the gear inside the movement that adjusts the time, thus adjusting the time of the electronic watch. The multiple magnets are arranged with alternating polarities, which makes the magnetic field formed by the multiple magnets more stable, enhances the air gap magnetic field strength, and improves the transmission efficiency between the rotating discs.

[0039] 3. By setting up multiple magnets 1 and multiple magnets 2 in an alternating polarity manner, the magnetic force of magnets 1 and magnets 2 can be constrained to the side of magnets 1 and magnets 2 away from turntables 1 and 2, thereby reducing the impact of magnets 1 and magnets 2 on the electrical components inside the movement.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1: Refer to Figure 1 , Figure 4 , Figure 6 and Figure 12 and Figure 15An embodiment of the present invention provides a high-precision electronic watch, comprising a watch case 1, a stem 26, and a rotating shaft 20. An outer shell 10 is fixedly connected to one side of the inner wall of the watch case 1. A movement 9 is fixedly connected to one side of the outer shell 10. An electronic timer 55 is fixedly connected to the middle of the movement 9. The stem 26 is disposed inside the electronic timer 55. One end of the stem 26 passes through the movement 9 and the watch case 1 and is fixedly connected to a second rotating disk 53. Multiple magnets 48 are fixedly connected to one side of the second rotating disk 53. The multiple magnets 48 are arranged alternately with one S pole pointing away from the second rotating disk 53 and adjacent magnets having their N poles pointing away from the second rotating disk 53, forming an alternating polarity ring magnetic array. A base plate 16 is provided at the bottom of the outer shell 10. Screws 38 are threaded to the four corners of the bottom of the base plate 16. The other ends of the multiple screws 38 are threaded to the four corners of the bottom of the outer shell 10. A partition 29, made of sodium polyacrylate, is fixedly connected to the top of the base plate 16.

[0059] After rotating screw 38 to remove it from the housing 10, pull the base plate 16 downward to detach it from the housing 10 and remove the partition 29 from the housing 10 to replace the partition 29.

[0060] Reference Figure 4 , Figure 9 and Figure 11 A partition 29 is set on one side of a turntable 53. A turntable 35 is set on one side of the partition 29. Multiple evenly distributed magnets 36 are fixedly connected to one side of the turntable 35. A cavity 13 is opened on the other side of the turntable 35. A rotating shaft 20 is inserted into the cavity 13. Two pull blocks 37 are fixedly connected to both sides of one end of the rotating shaft 20. A knob 5 is fixedly connected to the other end of the rotating shaft 20 through the side wall of the watch case 1. Multiple magnets 36 are arranged in an alternating manner with one S pole pointing away from the turntable 35 and adjacent magnets pointing away from the turntable 35 with their N poles pointing away from the turntable 35, forming a ring magnetic array with alternating polarities.

[0061] The base plate 16 is fixed to the bottom of the outer casing 10 so that the partition 29 is inserted between the second turntable 53 and the first turntable 35. At the same time, the side wall of the partition 29 is in close contact with the inner side wall of the outer casing 10. At this time, the moisture that enters the inside of the outer casing 1 through the gap between the rotating shaft 20 and the watch case 1 will be trapped inside the outer casing 10, and the partition 29 will absorb it, thereby preventing the moisture from entering the movement 9 inside the watch case 1 and thus corroding the parts inside the movement 9.

[0062] Turning the knob 5 on the back of the hand causes the rotating shaft 20 to drive the rotating disc 35 to rotate. With the cooperation of magnet 36 and magnet 48, the rotating disc 53 drives the shaft 26 to rotate, thereby driving the gears inside the movement 9 to rotate and adjust the time of the watch. Because the multiple magnets 36 and 48 form a ring magnetic array with alternating polarities, the magnetic field formed by the multiple magnets 36 and 48 is more stable, enhancing the air gap magnetic field strength and improving transmission efficiency. This avoids the situation where the rotating shaft 20 drives the rotating disc 35 to rotate but the rotating disc 53 does not rotate, thus improving the accuracy of adjusting the time of the electronic watch.

[0063] Example 2: Refer to Figure 2 , Figure 3 and Figure 8 A high-precision electronic watch has two grooves 18 on one side of the inner wall of the watch case 1. Slider 17 is slidably connected inside each groove 18. Both sliders 17 are slidably connected inside the two grooves 18. Clamping blocks 19 are fixedly connected to one side of each slider 17. Springs 40 are fixedly connected to the front and rear ends of the adjacent sides of the two clamping blocks 19. The two clamping blocks 19 are respectively set at the top and bottom ends of the outer side of the rotating shaft 20. A positioning groove is opened on the outer side of the rotating shaft 20. A protrusion is fixed on the adjacent side of the two clamping blocks 19. The protrusion is inserted into the positioning groove. Both the protrusion and the positioning groove are designed as arc-shaped structures.

[0064] By pulling the knob 5, the rotating shaft 20 slides to one side, causing the protrusion to exit the positioning groove. Thus, when the user turns the knob 5, the rotating shaft 20 can be rotated. After the electronic watch has finished adjusting the time, the knob 5 can be pushed to reset the rotating shaft 20. At this time, the elastic force of the spring 40 pulls the two clamping blocks 19 to move in opposite directions, so that the protrusion enters the positioning groove to clamp and fix the rotating shaft 20.

[0065] Reference Figure 4 , Figure 6 , Figure 12 , Figure 13 and Figure 14The outer side of the rotating shaft 20 has a slot 33, and the outer side of the handle shaft 26 has a groove 28. A fixed seat 25 is fixedly connected to the inner top wall of the outer casing 10. A push plate 11 is slidably connected inside the fixed seat 25. Springs 45 are fixedly connected to the four corners of the bottom end of the push plate 11. The other ends of multiple springs 45 are fixedly connected to the four corners of the inner bottom wall of the fixed seat 25. A fixed block 27 is fixedly connected to the bottom end of the push plate 11 through the inner bottom wall of the fixed seat 25. The bottom end of the fixed block 27 is provided with a raised texture 39, which is inserted into the groove 28. A top block 24 is slidably connected inside the fixed seat 25. A push rod 23 is fixedly connected to one side of the 24. One end of the push rod 23 passes through the partition 29 and has a sliding groove 51. Limiting grooves 50 are opened on both sides of the inner wall of the sliding groove 51. A pull rod 22 is slidably connected inside the sliding groove 51. A collar 30 is fixedly connected to one end of the pull rod 22. The collar 30 is set inside the groove 33. A through hole 52 is opened at the end of the pull rod 22 near the push rod 23. A top rod 49 is set inside the through hole 52. Limiting blocks 41 are fixedly connected to both ends of the top rod 49. One end of each of the two limiting blocks 41 is inserted into the two limiting grooves 50. The top rod 49 is made of elastic material.

[0066] The rotating shaft 20 moves to one side, which drives the pull rod 22 to move through the collar 30. The pull rod 22 drives the push rod 23 to pull the top block 24 out of the fixed seat 25. At this time, the spring 45 pushes the push plate 11 to move the fixed block 27 away from the handle shaft 26, so that the convex pattern 39 exits the concave pattern 28, thereby enabling the rotating shaft 20 to drive the handle shaft 26 to rotate.

[0067] Reference Figure 4 , Figure 5 , Figure 6 and Figure 12 The outer side of turntable 1 35 has a groove 34, and the outer side of turntable 2 53 has a groove 47. A movable ring 31 is set inside the groove 34. A movable rod 54 is fixedly connected to one side of the movable ring 31. One end of the movable rod 54 passes through the partition 29 and is fixedly connected to the movable ring 32. The movable ring 32 is set inside the groove 47. One end of each of the two pull blocks 37 has a mounting groove 43. An elastic plate 42 is slidably connected inside the two mounting grooves 43. The end of the rotating shaft 20 near the pull block 37 is inserted into the cavity 13. The two elastic plates 42 are inserted into the two arc-shaped grooves 14.

[0068] When the rotating shaft 20 moves to one side, the pulling block 37 slides inside the cavity 13. When the pulling block 37 moves to the inner wall of the cavity 13, it will drive the rotating disk 35 to move to one side, and drive the moving rod 54 to move through the moving ring 31, thereby causing the moving ring 32 to drive the rotating disk 53 and the stem 26 to move. This allows the gear on the outside of the stem 26 to mesh with the gear inside the movement 9, thereby enabling the stem 26 to adjust the time of the electronic watch. The working principle of the meshing between the gear on the outside of the stem 26 and the gear inside the movement 9 is prior art and is not shown in the attached drawings, so it will not be described in detail here.

[0069] Reference Figure 4 A protrusion 21 is fixedly connected to one side of the inner top wall of the outer casing 10. The protrusion 21 can restrict the movement of the push rod 23, thereby allowing the pull rod 22 to slide inside the sliding groove 51.

[0070] Example 3: Refer to Figure 10 and Figure 15 A high-precision electronic watch, wherein a dial 46 is fixedly connected to the top of the movement 9, and a pointer 15 is fixedly connected to the top center of the electronic timer 55, passing through the movement 9 and the dial 46 in sequence. A support ring 44 is fixedly connected to the outer side of the top of the dial 46.

[0071] The electronic timer 55 drives the pointer 15 to rotate, and the user can judge the time by judging the position of the pointer 15 on the dial 46. The ring 44 can support the pointer 15 to prevent it from bending downward due to vibration and rubbing against the dial 46 during long-term use, thus affecting the accuracy of the electronic watch.

[0072] Reference Figure 2 and Figure 10 A fixing strap 1 is rotatably connected to one side of the watch case 1. A fixing ring 4 is rotatably connected to one end of the fixing strap 1. A plug rod 3 is rotatably connected to the middle of the end of the fixing strap 1 near the fixing ring 4. A fixing strap 2 8 is rotatably connected to the end of the watch case 1 away from the fixing strap 1. Multiple evenly distributed plug holes 7 are opened on the fixing strap 2 8.

[0073] Place the watch case 1 on your wrist, then thread the second fixing strap 8 through the inside of the fixing ring 4, and adjust the position of the fixing ring 4 on the second fixing strap 8 according to the thickness of the wearer's wrist. Then insert the plug 3 into the corresponding plug hole 7 to fix the watch case 1 on the wrist.

[0074] Reference Figure 1 The bottom of the watch case 1 is provided with a watch cover 6, and the four corners of the bottom of the watch cover 6 are threaded with bolts 12. One end of each bolt 12 is threaded to the four corners of the bottom of the watch case 1.

[0075] The watch is removed from the case 1 by turning the screw 12 by hand, and then the cover 6 is removed from the bottom of the case 1, so that the watch 1 can be opened and the movement 9 inside the case 1 can be repaired.

[0076] Working principle: When the time of the electronic watch needs to be adjusted, the knob 5 can be pulled to move the rotating shaft 20 to one side. This, through the collar 30 and the pull rod 22, moves the push rod 23, causing the top block 24 to exit the fixed seat 25. This allows the spring 45 to push the push rod 23, causing the fixed block 27 to separate and the protrusion 39 to exit the concave groove 28, releasing the fixation of the stem shaft 26. At the same time, the protrusion on the clamp 19 will exit the positioning groove outside the rotating shaft 20, thus releasing the limitation on the rotating shaft 20. When the push rod 23 moves to the side of the protrusion 21, the protrusion 21 will push the push rod 23. The movement is limited, and the pulling block 37 on the rotating shaft 20 will be tightly pressed against the side wall of the cavity 13, and the elastic plate 42 will be engaged inside the arc-shaped groove 14. As the rotating shaft 20 continues to move, the limiting block 41 will retract into the through hole 52 under the pressure of the limiting groove 50 and compress the push rod 49. At the same time, the rotating shaft 20 will drive the first turntable 35 to move to one side, and drive the moving rod 54 to move through the first moving ring 31, thereby causing the second moving ring 32 to drive the second turntable 53 and the stem 26 to move, so that the gear on the outside of the stem 26 can mesh with the gear for adjusting the time inside the movement 9. Rotating knob 5 causes shaft 20 to rotate, driving turntable 35 to rotate. The interaction of magnets 36 and 48 causes stem 26 to rotate, thus rotating the time-adjusting gear inside movement 9. After time adjustment, shaft 20 can be pushed in the reverse direction. Because elastic plate 42 is engaged inside arc groove 14, shaft 20 will push turntable 35 to move. This, through the interaction of moving ring 31, moving rod 54, and moving ring 32, causes turntable 53 to move away from stem 26, allowing the gear on the outside of stem 26 to disengage from the time-adjusting gear inside movement 9. 35 will be pressed tightly against one side of the partition 29, and the pull rod 22 will move to the sliding groove 51. At the same time, the limiting block 41 will enter the limiting groove 50 under the elasticity of the top rod 49. At this time, the rotating shaft 20 will continue to be pushed. Under the pressure of the arc groove 14, the two ends of the elastic plate 42 will slide to both sides inside the mounting groove 43, so that the pull block 37 can continue to slide inside the cavity 13, so that the rotating shaft 20 can push the top block 24 to reset through the pull rod 22 and the push rod 23, so that the top block 24 can push the push plate 11 to drive the fixing block 27 close to the handle shaft 26 to fix the handle shaft 26.

[0077] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
