Description

Technical Field

[0001] The utility model relates to the technical field of quartz watches, and in particular to a quartz watch head with a large-capacity battery and a quartz watch. Background Art

[0002] A quartz watch is an electronic watch that uses quartz crystal oscillation to tell time. Quartz crystals produce regular and stable vibrations under a specific electric field, so they are widely used in timing tools. The core component of a quartz watch is a quartz crystal oscillator, which can produce high-frequency vibrations, and then drive the hands or other display components through circuit modulation to display time.

[0003] Compared with mechanical watches, quartz watches not only have high timekeeping accuracy, but also only require regular battery replacement for maintenance. However, existing quartz watches are limited by the industry's default dial size, resulting in a relatively small battery capacity. For some customers, a short battery replacement cycle will also cause a bad customer experience, and in some extreme cases, it is the direct reason for customers not to choose quartz watches.

[0004] Therefore, there is an urgent need for a quartz watch with a large-capacity battery. Utility Model Content

[0005] The utility model provides a quartz watch head with a large-capacity battery and a quartz watch, which solves the problem of short battery replacement cycle due to small battery capacity in existing quartz watches.

[0006] The technical solution of the utility model is as follows:

[0015] As a further technical solution, a crimping protrusion is provided on the positive electrode plate, and the crimping protrusion is pressed on the negative electrode plate.

[0016] As a further technical solution, the crimping protrusions are multiple and arranged in a circle with the battery as the center.

[0017] As a further technical solution, the crimping protrusion and the positive electrode plate are an integrated structure.

[0018] As a further technical solution, the circuit component includes an integrated circuit and a fine-tuning capacitor, the integrated circuit is detachably arranged on the first side of the main plate, the fine-tuning capacitor is arranged on the integrated circuit, and the integrated circuit is electrically connected to the positive electrode plate and the negative electrode plate.

[0019] The quartz watch movement with a large-capacity battery provided by the utility model has the following beneficial effects: the quartz watch movement with a large-capacity battery includes a main plate, a transmission gear train, an electromechanical transducer, a quartz oscillator, a circuit assembly, a watch hand assembly, and a power assembly.

[0020] The utility model also provides a quartz watch head, comprising any one of the above-mentioned quartz watch movements with a large-capacity battery.

[0021] The utility model also provides a quartz watch, comprising the above-mentioned quartz watch head and watch straps, wherein the number of the watch straps is two and the watch straps are arranged on the symmetrical sides of the quartz watch head.

[0022] The quartz watch provided by the utility model can be installed with a large-capacity battery by designing the positive electrode plate structure, so the battery life is much longer than that of existing quartz watches on the market. In addition, since other structures have not changed, only the layout of other components needs to be changed to reserve more space for the battery, avoiding the design of other components, greatly reducing the design cost and manufacturing cost of the enterprise, and ultimately improving the competitiveness of the enterprise.
