Description

Watchband and sports watch

Technical Field

The utility model relates to a motion wrist-watch technical field especially relates to a watchband and motion wrist-watch.

Background

The sports watch on the market at present realizes the monitoring of human motion data through wearing on human wrist. Since the reflection of the skin, bones, meat, fat and the like of the human body to light is a fixed value, the reflection of the capillary vessels and arterial veins in the human body tissue is a fluctuating value due to the fact that the pulse volume continuously increases and decreases, the heart rate data of the human body can be obtained by monitoring the reflection condition of visible light (such as green light) in the human body tissue. And to adopting the above-mentioned wrist-watch that obtains rhythm of the heart data of mode that detects light reflection intensity, guarantee that rhythm of the heart detecting element can the accurate test rhythm of the heart, be the contact surface that needs to guarantee rhythm of the heart detecting element and human body and form and maintain a more stable pressure range.

In these wearable sports watches that have now, when it wears on human wrist, usually can appear because human size is fat thin, motion or rock and the reason such as wearing mode, human detection portion (the back of the hand) takes place the deformation, leads to the pressure oscillation change, and the accuracy that influences data detection.

As shown in fig. 1-3, in a sports watch in the prior art, a curved surface structure 101 is disposed on a rear cover of the sports watch, a heart rate sensing element of the watch is disposed inside the curved surface structure 101, the sensing element includes a light emitting element for emitting light and a light receiving element for receiving light, the light emitted by the light emitting element penetrates through the curved surface structure 101, is reflected by a human skin 102 and then received by the light receiving element, and finally, intensity of the light received by the light receiving element is detected to obtain human heart rate data. The curved structure 101 in fig. 1 is for increasing the intensity of the reflected light received by the light receiving element, and for providing a greater pressure intensity, so as to ensure the stability of the heart rate data detected by the heart rate detecting element.

However, due to the difference in the wearing manner of the human body or the body size, the contact/attachment area between the human skin 102 and the curved transparent structure of the sensing element is directly affected, so that the stable pressure acting range of the curved transparent structure of the sensing element cannot be ensured. Fig. 2 shows the bonding state of the curved surface structure 101 and the wrist skin 102 when the human hand rotates/shakes, and fig. 3 shows the bonding state of the curved surface structure 101 and the wrist skin 102 when the watch strap is in a relaxed state, and it can be seen that in the state shown in fig. 2 and fig. 3, the light reflection surface formed by the sensing element and the human body is very small, the pressure effect of the human body skin 102 from the watch is also very small, and the pressure range required by the human heart rate detection cannot be achieved. Further, there is a problem that other direct light is incident on the light receiving element through the convex light transmitting member, causing interference.

To this, provide a watchband structure for motion wrist-watch, can effectual improvement wrist-watch and human skin's laminating effect, guarantee to set up the heart rate sensing element more accurate detection in the wrist-watch and obtain heart rate data.
