[0002] An electronic quartz clock is a timekeeping instrument that uses a battery as its power source, a quartz crystal oscillator as its time reference, and an integrated circuit to drive a stepper motor or display device to indicate the time. In the prior art, patent CN218273107 U discloses an electronic quartz clock with sound-controlled lighting, including a housing, a dial, and hands. The dial is mounted on one side of the housing, and the hands are installed inside the dial. An lighting mechanism is provided on the outside of the dial. A sound is provided on one side of the housing. A support structure is provided at the bottom of the housing. An adjustment knob is provided on one side of the housing. A protective structure is provided on the outer wall of the housing. This utility model separates the release paper from the adhesive, then places the base plate on the table and uses the adhesive to fix the base plate to the table. By covering the outside of the locking block, the cover fixes the housing to the table, preventing the device from tipping over. This achieves the stable placement function of the device, making it less prone to tipping over, facilitating viewing and fixing the device, and improving the stability of the device. However, the hands and dial of this device have a smooth flat design, and the structure of the hands and dial is relatively monotonous and has limited aesthetic appeal. Therefore, we propose an electronic quartz clock with a gear rotation effect. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: an electronic quartz clock with a gear rotation effect, including a back shell 1. A hollow shaft 2 is rotatably connected to the middle of the back shell 1 via a bearing 1. An hour hand 4 is located at the outer front end of the hollow shaft 2. A solid shaft 3 is rotatably connected to the inside of the hollow shaft 2 via a bearing 2. A minute hand 5 is located at the front end of the solid shaft 3. The back shell 1 of the electronic quartz clock contains a mechanical part and a circuit part. The mechanical part is a permanent magnet stepper motor that converts the electrical signals output by the circuit into the rotational motion of the rotor. The permanent magnet stepper motor can be a 28BYJ-48 stepper motor. The rotor consists of magnets and gears, and drives the minute hand 5 and hour hand 5 through the gear train. The solid shaft 3 or hollow shaft 2 corresponding to the hand 4 rotates. The gear system is usually composed of multiple compound gears, which reduce speed through different combinations of tooth numbers, so that the speed ratio of the minute hand 5 to the hour hand 4 is 60:1. The circuit part consists of a quartz oscillator and an integrated circuit. The quartz oscillator can be a 32.768kHz tuning fork type quartz resonator. The quartz oscillator generates stable pulses through the piezoelectric effect. The integrated circuit is responsible for dividing the high-frequency signal of the crystal oscillator and outputting one pulse per second to drive the stepper motor, so that the stepper motor drives the rotor to rotate. At the same time, a battery is installed in the rear shell 1 to provide power support for the operation of the electronic quartz clock. It also includes a gear mechanism 8.

[0021] The inner arc wall of the back cover 1 is provided with a scale ring 6, and the user can read the time value by the direction of the arrows of the hour hand 4 and minute hand 5 on the scale ring 6;

[0022] The scale ring 6 has a decorative frame 7 inside, which can cover part of the electronic quartz clock and better show the mechanical beauty of gear transmission.

[0023] Gear mechanism 8 includes gear 1 81, shaft 1 84, gear 4 85, and extension assembly 87. Gear 1 81 is located at the middle of the outer side of the hollow shaft 2. Gear 4 85 is rotatably connected to the upper side of the rear wall of the rear housing 1 via shaft 1 84. Gear 4 85 meshes with gear 1 81. Extension assembly 87 is provided at the lower end of the rear wall of the rear housing 1. Extension assembly 87 is installed in conjunction with gear 1 81. Gear mechanism 8 also includes gear 2 82, gear 3 83, and gear 5 86. Gear 2 82 is located at the rear end of the outer side of the hollow shaft 2. Gear 3 83 is provided at the outer front end of shaft 2, and gear 5 86 is provided at the outer front end of shaft 1. The extension assembly 87 includes shaft 2 871, gear 6 872, shaft 3 873, gear 7 874, and gear 875. Gear 6 872 is rotatably connected to the left and right ends of the lower side of the rear wall of the rear shell 1 through shaft 2 871. Gear 6 872 is meshed with gear 1 81. Gear 7 874 is rotatably connected to the lower end of the rear wall of the rear shell 1 through shaft 3 873. Gear 874 is rotatably connected to the lower end of the rear wall of the rear shell 1 through shaft 4. Gear 875 and gear 872 on the left are all meshed with gear 7 874. When using the electronic quartz clock, the hollow shaft 2 inside the clock drives the hour hand 4 to rotate, and the solid shaft 3 drives the minute hand 5 to rotate. During the rotation of the hollow shaft 2, the hollow shaft 2 drives gears 1 81, 2 82, and 3 83 to rotate. Gear 1 81 meshes with gears 4 85 and 6 872 to rotate synchronously. Gear 4 85 drives gear 5 86 to rotate through shaft 1 84. Gear 6 872 rotates around its corresponding shaft. The rotation of shaft 2 (871) causes gear 6 (872) on the left to rotate through meshing, which in turn drives gear 7 (874) to rotate. Gear 7 (874) then drives gear 8 (875) to rotate through meshing, thus keeping all the gears inside the electronic quartz clock in a dynamic state of rotation. This device is decorated with gear elements. The power provided by the rotation of the hour hand 4 inside the electronic quartz clock keeps all the exposed gears inside the device in a dynamic state of rotation, allowing users to directly appreciate the precise beauty of mechanical operation and enhancing the artistic value of the electronic quartz clock through visual layering.

[0024] A front cover frame 9 is provided at the outer front end of the rear shell 1, and the front edge of the rear shell 1 is sealed by the front cover frame 9.

[0025] The front cover frame 9 has a circular glass 10 inside, which allows users to view the internal structure of the electronic quartz clock.

[0026] The working principle of the electronic quartz clock with gear rotation effect provided by this utility model is as follows: When using the electronic quartz clock, the hollow shaft 2 inside the clock drives the hour hand 4 to rotate, and the solid shaft 3 drives the minute hand 5 to rotate. The time value is read by the direction of the arrows of the hour hand 4 and the minute hand 5 on the scale ring 6. During the rotation of the hollow shaft 2, the hollow shaft 2 drives gears 1 (81), 2 (82), and 3 (83) to rotate. Gear 1 (81) meshes with gears 4 (85) and 6 (872) to rotate synchronously. Gear 4 (85) drives gear 5 (86) to rotate through shaft 1 (84). Gear 6 (872) rotates around the corresponding shaft 2 (87). 1. The axis rotates, and the gear 6 872 on the left side drives the gear 7 874 to rotate through meshing. The gear 7 874 drives the gear 8 875 to rotate through meshing, so that all the gears in the electronic quartz clock are in a dynamic rotating state, allowing users to directly appreciate the precision beauty of mechanical operation. The visual layering enhances the artistic value of the electronic quartz clock. The decorative frame 7 partially obscures the inside of the electronic quartz clock, further highlighting the mechanical beauty of gear transmission. The front cover frame 9 seals the front edge of the rear shell 1, and the circular glass 10 allows users to view the internal structure of the electronic quartz clock.
