[0033] The utility model provides a kind of movement structure 100 and watch, wherein, movement structure 100 includes base plate 1, motor 2 and circuit board, base plate 1 is formed with battery mounting cavity 11, the circumferential of battery mounting cavity 11 is equipped with multiple heat dissipation grooves 12, heat dissipation groove 12 is communicated with the battery mounting cavity 11, when battery generates heat in working process, heat can be exported by multiple heat dissipation grooves 12, to ensure that battery is always in relatively appropriate and safe operating temperature range, base plate 1 is equipped with pivot on the side of battery mounting cavity 11, pivot is used to install the pointer of watch;In the technical scheme, circuit board adopts layered design, including the first circuit board 31 and the second circuit board 32 of laminated arrangement, the first circuit board 31 is used to control motor 2 start-stop, and the second circuit board 32 is used to monitor physiological index parameter of human body, by integrating the component for realizing different functions into two circuit boards respectively, the horizontal area of circuit board can be reduced, and the vertical space of base plate 1 is reasonably utilized, and moreover, layered interval design of circuit board can be more conducive to the export of circuit board heat, with the miniaturization of circuit board and better heat dissipation performance.
[0034] To improve the heat dissipation efficiency of heat dissipation groove 12, in the embodiment of the utility model, 5 heat dissipation grooves 12 are arranged on the side wall of battery mounting cavity 11, and each heat dissipation groove 12 is uniformly spaced, and the extension direction of heat dissipation groove 12 points to the center of battery mounting cavity 11, so that the heat generated by battery operation is more directly exported. To avoid that heat dissipation groove 12 exports heat to affect circuit board or other components in movement, heat dissipation groove 12 extends from battery mounting cavity 11 to the side away from circuit board, i.e. the outside of movement, so that the heat dissipated by battery and the ambient air complete heat exchange, thereby reducing battery operating temperature.
[0035] To further optimize the heat dissipation capacity of heat dissipation groove 12, the inner side wall of each heat dissipation groove 12 is provided with heat conduction layer 121, specifically, please further refer to Figure 2It is to be noted that the heat dissipation layer can be fixed to the inner side wall of the heat dissipation groove 12 in a manner of adhesion, or can be fixed in a manner of encapsulation, and the present application does not limit this, and in an embodiment of the present application, the heat conduction layer 121 is adhered to the inner side wall of the heat dissipation groove 12.

In addition, the heat-conductive silica gel is easy to apply and cure, is convenient to install and maintain, and has good electrical insulation, which is helpful to the safe operation of the electronic equipment.
[0036] With the natural aging of the battery, temperature fluctuation, battery self-discharge and battery quality problems, the chemical substances inside the battery will gradually lose stability, the sealing performance may become weak, causing electrolyte leakage.

When the battery leaks, the electrolyte will flow out of the heat dissipation groove 12 and be absorbed by the adsorption layer 122 at the bottom of the heat dissipation groove 12, thereby avoiding the electrolyte flowing in the movement and contacting the circuit board to cause the circuit board to fail.
[0037] In the technical scheme of the present application, the first circuit board 31 is fixed on the base plate 1 by bolts, and the second circuit board 32 is fixed on the first circuit board 31 by two pole columns 311.

[0038] The second circuit board 32 is provided with a blood oxygen concentration monitoring device 321 and a heart rate monitoring sensor 322 on the side facing the user's wrist. The blood oxygen concentration monitoring device 321 mainly works on the principle of Pulse Oximetry technology, which measures the oxygen saturation by emitting light of two different wavelengths (usually red and infrared) through the skin and blood and measuring the difference in absorption of these lights by oxyhemoglobin and deoxyhemoglobin. This method focuses on the concentration of oxygen in the blood. The heart rate monitoring sensor 322 uses the PPG technology. The PPG sensor monitors the heart rate by emitting light (usually green) and detecting changes in light absorption caused by changes in blood volume in blood vessels. This method mainly focuses on the rhythm of blood flow, i.e. the frequency of heartbeats. Thus, the watch has the function of monitoring the user's health.
