Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The applicant carries out detailed analysis on the problem that the existing intelligent wrist strap cannot be thinned further. The size of an infrared detection sensor used by the existing intelligent wrist strap is 2.36 mm. The infrared detection sensor limits further thinning of the smart wristband.
The applicant has proposed the following improvements on the basis of the foregoing analysis:
please refer to fig. 1, which is a schematic diagram illustrating an intelligent wristband with an infrared gesture recognition function according to the present application, including:
a band 11 having a wearing surface 111 that can be attached to a wrist;
a main plate 12 mounted to the belt member 11;
an infrared detection sensor 13 electrically connected to the main board 12;
the infrared detection sensor 13 and the main board 12 are arranged in parallel in the thickness direction of the main board 12.
The band 11 is used to put the smart band on the wrist as a whole. The strap 11 encircles the wrist or at least partially encircles the wrist when worn. It should be noted that the band member 11 refers to a band shape formed to extend in a direction around the wrist. The specific form of the band 11 may be a complete ring or a semi-encircling ring. The belt-shaped member 11 may be a metal member, a leather member, a porcelain member, or a plastic member. In a particular use, the strap 11 is bound or restrained to the wrist. The belt member 11 has a wearing surface 111 to be attached to the wrist. The wear surface 111 may be understood to be the interior surface of the smart wristband that conforms to the wrist during use. The inner surface is a curved surface.
The main plate 12 is mounted to the belt member 11. The motherboard 12 performs functions similar to those of the motherboard 12 of the computer device. The motherboard 12 may typically include a processing chip or processor, memory. A power input port or power module may also be provided on the motherboard 12. Motherboard 12 can execute coded computer program instructions to implement the functionality of an application program.
The infrared detection sensor 13 is for detecting a change in the infrared signal. The infrared detection sensor 13 is electrically connected to the main board 12. The main board 12 may generate a corresponding application control instruction according to a change of the infrared signal received by the infrared detection sensor 13. The smart wristband has a first plane 121 perpendicularly intersecting the wearing surface 111; the projection height of the infrared detection sensor 13 on the first plane 121 is not more than 2.36 mm. More preferably, the thickness of the smart band may be reduced to the limit size of the infrared detection sensor 13, which is less than 1 mm.
Referring to fig. 2, further, in an embodiment provided by the present application, the infrared detection sensor 13 includes an infrared emitter 131 and two infrared receivers 132.
The infrared emitter 131 emits an infrared signal in a predetermined direction. The user or operator can make a preset action within the propagation range of the infrared signal. The infrared signal is reflected by a preset action of the user or operator. The reflected infrared signal is received by infrared receiver 132. Subsequently, the infrared receiver 132 may transmit the intensity information of the received infrared signal over time to the main board 12. The corresponding processor on the motherboard 12 performs processing and analysis to generate a control command.
Further, in an embodiment provided herein, the two infrared receivers 132 are distributed on the same side of the infrared transmitter 131.
Please refer to fig. 3 and 4. FIG. 3 is a diagram illustrating a user's finger in a first position. Fig. 4 is a schematic diagram showing the intensity information of the infrared signals received by the two infrared receivers 132 as a function of time when the user's finger performs the action shown in fig. 3. Since the two infrared receivers 132 are distributed on the same side of the infrared transmitter 131. Thus, simple comparison of the state diagrams of the intensity information of the infrared signals of the two infrared receivers 132 over time can identify simple actions. Because the action is simple, the recognition algorithm can be simple and the realization cost is low. Moreover, the action can be set simply, the error rate is low, and the user experience is good. In a particular application, for example, for music playing applications. When the finger is quickly slid in a first direction, it may indicate an upturn. When the finger is swiftly slid in a second direction opposite to the first direction, it may indicate to be turned down. Slowly sliding the finger in the first direction may indicate flipping down to the end. When the finger is slowly slid in the second direction, it may indicate flipping up to the beginning. These actions can be realized by simply recognizing the time-varying state diagram of the intensity information of the infrared signals received by the two infrared receivers 132 distributed on the same side of the infrared transmitter 131.
The smart wristband has a first plane 121 that perpendicularly intersects the wear surface 111. The first plane 121 here can be understood as a plane normal to the direction of extension of the wrist. The projection height of the infrared detection sensor 13 in the first plane 121 does not exceed 1 mm. Alternatively, it can be considered that the infrared detection sensor 13 is not more than 1mm higher than the wrist.

said mounting surface being parallel or coincident with the first plane 121.
In the embodiment provided in the present application, the infrared detection sensor 13 is mounted on a flexible circuit board, having a mounting surface. The mounting surface is parallel to or coincides with the first plane 121. Alternatively, the infrared detection sensor 13 may be mounted on the side of the belt member 11. When the first plane 121 is a vertical plane, the mounting surface is also a vertical plane.

the mounting face intersects the first plane 121.
Also, in the embodiment provided in the present application, the infrared detection sensor 13 is mounted to the flexible circuit board, having a mounting surface. The mounting surface intersects the first plane 121. When the first plane 121 is a vertical plane, the mounting surface obliquely intersects the vertical plane. The advantage of this is that, on the one hand, when the height direction of the infrared detection sensor 13 is inclined by a certain angle, when the height of the infrared detection sensor 13 exceeds 1mm, the thickness of the smart wristband can still be reduced to no more than 1 mm. On the other hand, when the user slides the fingers on the back of the hand, the size of the reflection part of the middle part of the finger as the infrared signal is larger, the reflection intensity of the infrared signal can be improved, and the identification precision can be improved.
