Problems solved by technology

In this way, it seems inevitable to streamline the pointer transmission unit of the watch. At present, manufacturers of smart watches with physical hands have encountered such a problem. Most of the direction of streamlining considers the gearbox, and it has never been from a place other than the gearbox. make design improvements

Embodiment 1

[0036] as attached figure 1 As shown, the smart watch is the same as a traditional watch, including the crown. The difference is that there is no transmission mechanism between the crown and the movement.

[0037] The crown comprises a crown head 11 and a shaft 12 fixedly connected to the crown head 11 .

[0038] When the user turns the crown head by hand, the shaft 12 rotates with the crown head 11 , and the rotation axis of the shaft 12 is the central axis of the shaft 12 itself.

[0039] There is a spring between the crown and the bezel ( figure 1 not shown in ), when the user presses and releases the crown 1, the crown can be reset under the action of a spring.

[0040] In this way, the shaft 12 has positive and negative displacements in the axial direction (Y direction), and the sum of the displacements is 0. Therefore, the shaft is reset along with the crown.

[0041] The system includes an optical tracking surface sensor (Rotational Tracking on Shaft or Optical Trac...

Embodiment 2

[0049] How to adjust the hands of a smart watch.

[0050]When the position of the pointer needs to be adjusted, start the pointer adjustment procedure, and then firstly need to select which pointer to adjust.

[0051] In the default program, the default pointer can be set as the adjustment pointer, but often the default pointer is not the pointer that needs to be adjusted, or other pointers need to be adjusted after the default pointer is adjusted.

[0052] Traditional watches use only one pointer, such as the minute hand, and after the minute hand completes a circle, the hour hand turns a small angle, that is, the minute hand is used to drive the hour hand.

[0053] However, in the smart age, this adjustment method is too slow.

[0054] In this application, the crown is set to be movable in the Y direction, and the optical tracking surface sensor is used to judge whether the pointer moves in the Y direction to switch the pointer. If the crown does not move back and forth on...

Embodiment 3

[0060] In the adjustment process of mechanical watches, we turn the crown many times, but the pointer often stops rotating soon after we stop turning the crown, instead of strictly proportional to the rotation angle of the pointer according to the rotation angle of the crown.

[0061] Therefore, in the adjustment process, we creatively set a sudden stop step, which has never been used or proposed in the adjustment of all watches.

[0062] The specific steps for sudden stop are:

[0063] The processor includes a timer, and when determining the rotation speed of the watch hands and controlling the rotation of the adjustment hands of the watch, the processor detects whether the timer is started;

[0064] If the timer is not started, then start the timer; if the timer has been started, refresh the time of the timer;

[0065] When the timer time reaches the time threshold T, if the adjustment pointer is still rotating, stop the rotation of the adjustment pointer.

[0066] Prefera...

Abstract

The present invention relates to an adjustment system and method for the pointer of a smart watch. The system comprises a crown, an optical tracking surface sensor and a processor; the crown comprisesa crown head and a shaft rod; the crown head is used by a user to press the crown to move in a Y direction; the shaft rod is fixedly connected to the crown head; the shaft rod rotates along the central axis of the shaft rod when the crown head rotates; the optical tracking surface sensor deviates from the shaft rod by a distance and is used for tracking the movement of the shaft rod; and the processor can calculate motion detected by the optical tracking surface sensor.

Description

technical field [0001] The invention relates to a smart watch, in particular to a method and system for adjusting pointers of the smart watch. Background technique [0002] At present, when the pointer of a watch with a physical pointer is adjusted, a crown with a groove is usually used, and the crown is pulled down to a different position with the thumb and forefinger (usually the crown is pulled out), and then turned clockwise or counterclockwise The crown, which drives the transmission mechanism connected with the crown in this position, so that the movement is transmitted to the gearbox, which then drives the hands to rotate clockwise or counterclockwise. [0003] In the era of intelligent watches, there are two directions, one is fully intelligent, which tends to be electronic watches, and even uses electronic pointers to simulate physical pointers; the other is semi-intelligent, that is, retaining physical pointers and adding intelligent modules. Major watch manufactu...
