In the present embodiment, the touch areas 14 may be formed on the lower case 12, for example, on the peripheral side 122 of the lower case 12, so as to facilitate the user's operation and the miniaturized design of the product main body 1.

When the touch key senses that a human hand approaches or touches, the touch key can cause the electrical parameters of the touch key to change, so that a trigger signal is generated and output to a system for key response. However, as for the smart band that needs to be worn on the human body in normal use, the human hand often touches the main body 1 of the smart band carelessly, causing the touch key 3 to be triggered by mistake, resulting in misoperation.

In order to solve the problem of misoperation of a user in the using process, in the embodiment, a plurality of touch keys 3 are preferably arranged in the shell of the smart bracelet, and when the user touches the plurality of touch keys 3 at the same time, the system automatically judges that the key operation is effective; otherwise, it may be considered that one of the touch keys 3 is erroneously triggered and does not respond to the key operation of this time.

In consideration of saving cost, reducing the difficulty of arranging components in the shell, being convenient for a user to use and the like, the embodiment preferably configures two touch keys 3 for some key instructions to jointly respond to user operations, such as a screen locking instruction, an unlocking instruction, a confirmation instruction and the like, and the system performs key response only when a human hand touches the two touch keys 3 simultaneously.

Specifically, the sensing regions 31 of the two touch keys 3 may be respectively adhered to the inner sides of two opposite side surfaces among the peripheral side surfaces 122 of the lower case 12 by the double-sided tape 6, as shown in fig. 3. Correspondingly, an independent touch area 14 is formed on each of the two side surfaces, and the two touch areas 14 are designed to be opposite to the sensing areas 31 of the two touch keys 3 in position one by one. When a human hand touches the touch area 14, the corresponding touch key 3 senses the approach of the human hand and causes the electrical parameter of the touch key to change, thereby generating a trigger signal. The main control board 4 can be used to receive the trigger signals output by the two touch keys 3, and then automatically identify whether the user touches the corresponding key 3.

As a preferred embodiment, the touch key 3 preferably adopts a capacitive touch key, when a human hand approaches the sensing area 31, the capacitance value of the sensing capacitor formed by the touch key itself is increased due to the fact that the sensing capacitor formed between the human hand and the ground is connected to the touch key in parallel, and when the capacitance value of the touch key 3 is increased, the touch key outputs a trigger signal to be provided to the smart band for executing a corresponding operation. The capacitive touch key can penetrate through the shell made of the insulating layer material, the effective touch of a finger can be accurately detected, and the sensitivity, stability, reliability and the like can not be changed due to the change of environmental conditions or long-term use.

In the present embodiment, FPC flexible circuit boards 32 may be provided on the two touch keys 3, respectively, as shown in fig. 4. Specifically, one end of the FPC flexible circuit board 32 may be connected to the touch key 3, and the other end forms a free end 33 for electrical connection with the main control board 4.

As a preferred embodiment, FPC flexible circuit board 32 may be extended from side surface 122 of lower case 12 to bottom surface 121 of lower case 12, as shown in fig. 3, with free end 33 of FPC flexible circuit board 32 positioned directly above bottom surface 121 of lower case 12. As shown in fig. 4 and 5, the double-sided adhesive tape 7 is adhered to the bottom surface of the free end 33 of the FPC flexible circuit board 32, and as shown in fig. 4 and 5, the free end 33 of the FPC flexible circuit board 32 is adhered to the inner side of the bottom surface 121 of the lower case 12 by the double-sided adhesive tape 7, and the sensing area 31 of the touch key 3 is adhered to the inner side of the peripheral side surface 122 of the lower case 12 by the double-sided adhesive tape 6, thereby completing the fixed installation of the touch key 3 in the lower case 12.

In this embodiment, a bonding pad 34 is disposed on the top surface of the free end 33 of the FPC flexible circuit board 32, a key elastic sheet 41 is welded on the bottom surface of the main control board 4, the disposition position of the main control board 4 in the lower casing 12 is designed at a position adjacent to the bottom surface 121 of the lower casing, and after the main control board 4 is mounted in place in the lower casing 12, the key elastic sheet 41 is just pressed against the bonding pad 34, as shown in fig. 3, the touch key 3 and the main control board 4 can be electrically connected by the contact conduction of the key elastic sheet 41 and the bonding pad 34.
