Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings.

For the convenience of understanding the wearable device provided in the embodiments of the present application, an application scenario thereof is first described below. The wearable device can be but is not limited to portable electronic devices such as a smart watch and a smart bracelet.

At present, the intelligent wrist-watch with body temperature measurement function, its temperature measurement module can be divided into two main categories: one is a non-contact temperature measurement module represented by infrared temperature measurement. The temperature measurement module has a complex structure and high cost, needs more space for arranging the temperature measurement module and is difficult to realize. In addition, the non-contact temperature measurement module based on infrared temperature measurement usually needs to occupy the space of the shell of the smart watch so as to realize the emission of infrared light. This may cause the non-contact temperature measurement module to affect the appearance of the smart watch.

When the temperature measuring module is specifically arranged, a hole can be formed in the shell, so that the temperature sensor can be placed in the hole; or, a heat conduction column of a simple structure connected with the temperature sensor is extended out of the hole to realize the temperature measurement. By adopting the scheme, the measurement error is larger because the heat conductivity coefficient of the shell is different, and the shell is greatly influenced by the environment. In addition, through trompil on the casing to place temperature sensor in downthehole, lead to wearing the waterproof problem difficult solution of product. If the temperature sensor is wrapped by the sealing member, the measurement error of the temperature sensor is large.

According to the introduction, most of the current smart watches with the temperature measuring module measure the temperature of the skin of the wrist of a human body. However, the wrist skin temperature and the body temperature are not a concept, and the measurement of the wrist skin temperature is greatly influenced by the ambient temperature. Therefore, the wrist skin temperature cannot accurately reflect the body temperature.

Based on this, this application provides a wearable equipment, this wearable equipment is through setting up environment temperature measurement module and skin formula temperature measurement module simultaneously to the algorithm is input to environment temperature data and the skin temperature data that will obtain, can obtain more accurate human temperature measurement result.

The skin temperature thus collected through the contact portion 40312 can be transmitted to the second temperature sensor 401 through the fixing portion 40311 and the second circuit board 4021. With continued reference to fig. 15, in some possible embodiments of the present application, the second circuit board 4021 may be connected to the contact portion 40312 and the fixing portion 40311 through the thermal conductive adhesive 303, so that the skin temperature collected through the contact portion 40312 can be directly transmitted to the second circuit board 4021, which is favorable for improving the accuracy of temperature measurement.

In this embodiment, the key is not connected to any other functional module except for collecting the ambient temperature, and pressing or rotating the key may not be used to implement any function, and such a key may be referred to as a "fake key" in this application.

In order to improve the aesthetic appearance of the wearable device and avoid interference with the operation of the function keys, the length of the portion of the key cap 201 of the dummy key 2b protruding outside the housing 1 may be reduced. For example, referring to fig. 18, fig. 18 shows a setting manner of the fake key 2b in the wearable device according to an embodiment of the present application. In this embodiment, the surface of the key cap 201 of the pseudo key 2b may be designed to be adapted to the surface contour of the connecting wall 1012 of the housing 1, so as to improve the continuity of the surface contour of the wearable device and improve the appearance thereof.

With continued reference to fig. 22a, in the embodiment shown in fig. 22a, the first heat conducting end 601 extends into the key slot 104 of the housing 1 for mounting a key (function key or dummy key).

In addition, the first heat conducting end 601 is arranged in the key slot 104, so that the structure and the processing process of the shell 1 can be effectively simplified.

Since the first heat conductive end 601 of the heat conductive structure 6 can extend into the key slot 104, the second heat conductive end 602 is located in the accommodating space 103. Referring to fig. 21 and fig. 22a together, in a possible embodiment of the present application, a hollow-out area 6031 may be further disposed on the connecting portion 603 of the heat conducting structure 6, and the hollow-out area 6031 may be used to avoid a key rod of the key, so as to avoid interference with the operation of the key.
