Description

Mechanical time-traveling pointer type quartz clock movement

Technical Field

The invention relates to the field of timepieces, in particular to a mechanical travel time pointer type quartz clock movement.

Background

Pointer type electronic quartz clock is used as traditional timing product, because timing is accurate, has obtained wide application in people's daily life. The pointer type quartz clocks and watches on the market at present can be divided into two types, namely a leapfrog type and a second-sweeping type according to the moving mode of a pointer.

Wherein: the leapfrog type has the defects that the noise is high, when the pointer jumps, the noise is high, the jumping sound of a gear structure 'click-click' can be heard, and particularly, the noise of the jumping of the pointer is obvious in a quiet environment. For example, when people stop at night and need to take a rest, the noise of the jumping of the pointer causes great trouble to the rest of people.

In addition, because the step width of each step of the leapfrog movement is large, once the step is blocked due to some reason, the step is two steps each time according to the operating characteristic of the pointer type quartz clock stepping motor, and the pointer has the accumulated time deviation caused by slow seconds and the step in a large range at 12 degrees.

The second sweeping machine type has the defects of special and complex structure and complicated production process; due to the structural particularity, the overall requirement on the precision of the gear structure is high, once the size of a certain part has slight deviation or the assembling method is incorrect, the gear structure is easy to block, the operation is not smooth, the overall qualified rate of products is low, the resource loss and waste are caused, and the overall cost is high finally due to various factors.
