The main board <NUM> is located in the receiving cavity, and a processor is located on the main board <NUM>.

As illustrated in <FIG>, <FIG> and <FIG>, in an embodiment, the electronic device <NUM> includes an electrical coupling assembly <NUM>. The electronic device <NUM> can be charged and transmit data through the electrical coupling assembly <NUM>. The electrical coupling assembly <NUM> includes one or more fixing members <NUM>. The fixing member <NUM> has a first end connected to the main board <NUM> and a second end passing through the casing <NUM> (the back cover) and exposed from the casing <NUM> (the back cover), such that the fixing member <NUM> can fix the main board <NUM> to the casing <NUM> (the back cover). The electronic device <NUM> can be charged through the fixing member <NUM> or can transmit data through the fixing member <NUM>. It could be understood that the fixing member <NUM> capable of charging or transmitting data includes three situations: first, a single fixing member <NUM> has a charging function but cannot transmit data; second, a single fixing member <NUM> can transmit data but has no charging function; third, a single fixing member <NUM> has both a charging function and the ability to transmit data. When a single fixing member <NUM> has the charging function but cannot transmit data, another fixing member <NUM> capable of transmitting data can be provided at the same time, such that the electronic device <NUM> is charged through a part of the fixing members <NUM> and transmits data through another part of the fixing members <NUM>. When a single fixing member <NUM> is capable of charging and transmitting data, the electronic device <NUM> can be provided with the single fixing member <NUM> to be charged and transmit data, or can be provided with a plurality of fixing members <NUM> to improve the efficiency of charging and transmitting data.

As illustrated in <FIG>, <FIG> and <FIG>, the electrical coupling assembly <NUM> includes a connector <NUM> and at least one fixing member <NUM>. The connector <NUM> and the fixing member <NUM> are spaced apart from each other and arranged in parallel. It could be understood that the connector <NUM> and the fixing member <NUM> are spaced apart from each other; that is, they do not interfere with each other, there is a space between the two, and the connector <NUM> and the fixing member <NUM> are parallel or approximately parallel. In an embodiment, the connector <NUM> is a pogo pin connector and used for charging or transmitting data. The fixing member <NUM> can restrain the main board <NUM> and the casing <NUM>, such that the pogo pin connector is kept in abutment with the main board <NUM> under the restraint of the fixing member <NUM>, thereby realizing electrical connection. The connector <NUM> passes through the casing <NUM> and is electrically connected to the main board <NUM>, and an end of the connector <NUM> connected to the main board <NUM> can be retracted. When the connector <NUM> is connected to the main board <NUM>, the end of the connector <NUM> connected to the main board <NUM> is in a compressed state, such that a resilient force exists between the connector <NUM> and the main board <NUM>. The first end of the fixing member <NUM> is connected to the main board <NUM>, and the second end thereof passes through the casing <NUM> and is exposed from the casing <NUM>, such that the fixing member <NUM> can fix the main board <NUM> to the casing <NUM>. The casing <NUM> and the middle frame <NUM> are fixed by an adhesive, and the adhesive forms an adhesive layer with a large width, such that it is waterproof and dustproof between the casing <NUM> and the middle frame <NUM>, thereby effectively protecting the electronic components inside the electronic device <NUM> and prolonging the service life of the electronic components. The electronic device <NUM> can be charged or transmit data through the fixing member <NUM>.

In an embodiment, the first connecting member <NUM> is configured as a screw, and the second connecting member <NUM> is configured as a nut. In the thickness direction of the wearable device <NUM>, the second connecting member <NUM> is embedded in the main board <NUM>. The first connecting member <NUM> passes through the casing <NUM> and is fitted with the second connecting member <NUM> by threads, such that the main board <NUM> is fixed to an inner surface of the casing <NUM>. In an embodiment, an outer surface of the first connecting member <NUM> is plated with gold or rhodium-ruthenium alloy to form a first plating (not shown), such that the first connecting member <NUM> has better electrically conductive performance. An outer surface of the second connecting member <NUM> is plated with gold or rhodium-ruthenium alloy to form a second plating (not shown), such that the second connecting member <NUM> has better electrically conductive performance. When the first connecting member <NUM> and the second connecting member <NUM> are fixed by threads, the first plating is in contact with the second plating. When the electronic device <NUM> is coupled with an external power supply by the fixing member <NUM>, the external power supply can charge the electronic device <NUM> through the first connecting member <NUM> and the second connecting member <NUM>; or when the electronic device <NUM> is coupled with an external device by the fixing member <NUM>, data can be transmitted between the electronic device <NUM> and the external device through the first connecting member <NUM> and the second connecting member <NUM>.

As illustrated in <FIG>, <FIG>, and <FIG>, in an embodiment, an adhesive layer is provided between an end surface of the casing <NUM> and the middle frame <NUM>, and the adhesive layer fixedly connects the casing <NUM> to the middle frame <NUM>. It could be understood that the adhesive layer fills a gap between the end surface of the casing <NUM> and the middle frame <NUM>, and the adhesive layer has a large width, thereby achieving the sealing between the end surface of the casing <NUM> and the middle frame <NUM> and allowing the electronic device <NUM> to be waterproof and dustproof.

In an embodiment, the electrical coupling assembly <NUM> includes two connectors <NUM> and two fixing members <NUM>. The casing <NUM> is provided with a first through hole <NUM>, a second through hole <NUM>, a third through hole <NUM>, and a fourth through hole <NUM>. One connector <NUM> passes through the first through hole <NUM>, the other connector <NUM> passes through the fourth through hole <NUM>, and the two fixing members <NUM> pass through the second through hole <NUM> and the third through hole <NUM> respectively. Each connector <NUM> has a first end exposed from the casing <NUM> and a second end electrically connected to the main board <NUM>, and a resilient force exists between each connector and the main board <NUM>. Each fixing member <NUM> has a first end exposed from the casing <NUM> and a second end fixedly connected to the main board <NUM>, and fixes the main board <NUM> to the casing <NUM>, and at the same time, the resilient force between the connector <NUM> and the main board <NUM> is counteracted. In another embodiment, the electrical coupling assembly <NUM> includes M connectors <NUM> and N fixing members <NUM>, wherein M is greater than or equal to <NUM> and N is greater than or equal to <NUM>. The M connector(s) <NUM> and the N fixing member(s) <NUM> pass through the casing <NUM> and are electrically connected to the main board <NUM> and exposed from the casing <NUM>. The electronic device <NUM> is charged through the connector(s) <NUM> and transmits data through the fixing member(s) <NUM>; or the electronic device <NUM> transmits data through the connector(s) <NUM> and is charged through the fixing member(s) <NUM>; or the electronic device <NUM> is charged through a part of the connectors <NUM> and a part of the fixing members <NUM> and transmits data through another part of the connectors <NUM> and another part of the fixing members <NUM>; or the connector(s) <NUM> can be used for charging and data transmission, and the fixed member(s) <NUM> can be used for charging and data transmission. All the possibilities will not be exhausted herein. In yet another embodiment, the electrical coupling assembly <NUM> is composed of fixing members <NUM>, and the number of the fixing members <NUM> is greater than or equal to one.
