Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of intelligent terminals, and in particular to a flexible wristband. Background Art
[0002] Natural and realistic human-computer interaction is an essential requirement for Extended Reality (XR). As a device that can collect myoelectric signals from the wrist, the wristband has become a research direction for barehanded interaction. Generally, the wristband includes several signal acquisition modules, and signal acquisition and data processing are realized by using the signal acquisition modules to contact the skin. Summary of the Invention
[0003] This Summary of the Invention section is provided to introduce concepts in a brief form that will be described in detail in the subsequent Detailed Description section. This Summary of the Invention section is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to be used to limit the scope of the claimed technical solution.
[0004] The present disclosure provides a flexible wristband.
[0005] The present disclosure adopts the following technical solutions.
[0006] In some embodiments, the present disclosure provides a flexible wristband, including: a plurality of signal acquisition modules, and the adjacent signal acquisition modules are connected by silicone;
[0007] The signal acquisition module includes a spiral spring, a pin shaft, a pin shaft fixing bracket, a wire, and a main board;
[0008] Wherein, one end of the spiral spring is connected to the pin shaft fixing bracket, the other end is connected to the pin shaft, the bottom of the pin shaft is fixedly connected to the signal acquisition module, the wire is wound around the wire groove opened on the pin shaft fixing bracket, and one end of the wire passes through the inside of the silicone and is connected to the main board of the adjacent signal acquisition module, and the pin shaft fixing bracket can rotate along the axial direction of the pin shaft.
[0009] The flexible wristband provided by the embodiments of the present disclosure includes: a plurality of signal acquisition modules, which are connected by silicone between adjacent signal acquisition modules; the signal acquisition module includes a torsion spring, a pin shaft, a pin shaft fixing bracket, a wire, and a main board; wherein, one end of the torsion spring is connected to the pin shaft fixing bracket, the other end is connected to the pin shaft, the bottom of the pin shaft is fixedly connected to the signal acquisition module, the wire is wound around a wire groove opened on the pin shaft fixing bracket, and one end of the wire passes through the inside of the silicone and is connected to the main board of the adjacent signal acquisition module, and the pin shaft fixing bracket can rotate along the axial direction of the pin shaft. It can be seen that when the user's wrist diameter is large and the module needs to be stretched, the silicone connecting between adjacent modules is stretched, and at the same time, the wire inside the silicone is also subjected to a stretching force. Furthermore, the wire will drive the pin shaft fixing bracket to rotate, elongating the wire by a certain length. At this time, the internal torsion spring is stressed. When the stretching of the wristband ends, the torsion spring can release part or all of the elastic force, so that the wire retracts into the wire groove of the pin shaft fixing bracket under the action of the elastic force of the torsion spring. The flexible wristband provided by the embodiments of the present disclosure can stably transmit signals in the stretched state, and the internal wire can be freely retracted and extended.

[0030] The following will describe in detail the solutions provided by the embodiments of this disclosure with reference to the accompanying drawings.
[0031] As Figure 1 、 Figure 2 and Figure 3 shown, the flexible wristband provided by the embodiments of this disclosure includes: a plurality of signal acquisition modules, and the adjacent signal acquisition modules are connected by silica gel;
[0032] The signal acquisition module includes a clock spring 1, a pin shaft 2, a pin shaft fixing bracket 3, a wire 4 and a main board 5;
[0033] One end of the spiral spring 1 is connected to the pin shaft fixing bracket 3, and the other end is connected to the pin shaft 2. The bottom of the pin shaft 2 is fixedly connected to the signal acquisition module. The wire 4 is wound around the wire groove formed in the pin shaft fixing bracket 3, and one end of the wire 4 passes through the silicone and is connected to the main board 5 of the adjacent signal acquisition module. The pin shaft fixing bracket 3 can rotate along the axial direction of the pin shaft 2.
[0034] In some embodiments, due to the large individual differences in the user's wrist and the need to pass the wristband through the palm when wearing the wristband, a flexible connection is generally used between each module. Therefore, how to ensure a reliable connection between the mechanical and electrical components becomes an urgent technical problem to be solved. As Figure 1 and Figure 2 shown, the flexible wristband provided by the embodiments of the present disclosure is composed of a signal acquisition module and silicone. The silicone is used for mechanical connection between adjacent modules to ensure the strength and elasticity of the wristband. The connection method can adopt two-color injection molding or other connection processes, which are not specifically limited herein.
[0035] In some embodiments, as Figure 3 and Figure 4 shown, the signal acquisition module is composed of an upper shell, a spiral spring fixing cover, a spiral spring, a pin shaft fixing bracket, a pin shaft fixing circlip, a wire, a copper buckle, a spring piece, a main board, a lower shell, and a pin shaft.
[0036] In some embodiments, as Figure 5 shown, the bottom of the lower shell has probe holes for connection to the test, and a pin shaft groove for preventing the pin shaft from rotating. There are wire passing holes on both sides of the signal acquisition module to allow the wire to pass through.
[0037] In some embodiments, as Figure 6 and Figure 7 shown, there are several probes under the main board, which are in contact with the wrist skin through the lower shell; there are two circular copper leakage areas on the side of the pin shaft above the main board for contact with the spring piece to achieve conduction.
[0038] In some embodiments, as Figure 8 shown, the lower end of the pin shaft is in imitation fit with the lower shell to ensure that the pin shaft cannot rotate. The middle and upper sections of the pin shaft are designed with a pin shaft fixing circlip to ensure axial fixation of the pin shaft. The upper part of the pin shaft is designed with a spiral spring slot to fix one end of the spiral spring.
[0039] In some embodiments, the lower end of the pin shaft fixing bracket contacts and limits the lower shell, there is a pin shaft hole in the middle, and the upper end is limited by the pin shaft fixing circlip. The pin shaft fixing bracket can rotate along the axial direction of the pin shaft.
[0040] In some embodiments, as Figure 9As shown, the elastic piece can be installed on the pin fixing bracket through double-sided tape and can rotate around the axis with the pin fixing bracket. One end of the elastic piece is welded to one level of the wire, and the other end contacts the copper leakage area of the main board to achieve conduction. One of the elastic pieces contacts the copper leakage area of the inner ring on the main board, and the other elastic piece contacts the outer ring.
[0041] In some embodiments, the strength of the wire can be enhanced by conventional measures such as adding bulletproof wire to the wire to increase the wire diameter, ensuring that the wire will not break during use and guaranteeing the reliability of the wire.
[0042] In some embodiments, the wire on the side of the elastic piece can be fixed to the pin fixing bracket through conventional processes such as knotting, and the entire wire is wound in the corresponding wire winding groove of the pin fixing bracket. The length of the wire is set according to the limit length when the user wears the wristband.
[0043] In some embodiments, as Figure 10 shown, the other side of the wire passes through the silicone interior and the wire passing holes in the adjacent module lower shell and is welded to the main board inside the adjacent module. The wire is fixed by installing a copper buckle in the adjacent lower shell.
[0044] In some embodiments, when it is necessary to increase the diameter of the entire wristband, the wire will drive the pin fixing bracket to rotate, thereby achieving the elongation of the wire. At this time, the coil spring is stressed. When the size is small, the wire returns to its original state under the action of the stressed coil spring.
[0045] In some embodiments, as Figure 11 shown, the coil spring is installed on the pin fixing bracket, with the inner side fixed to the pin and the outer side fixed to the side wall of the pin fixing bracket, and can drive the pin bracket to rotate when the wire is stretched.
[0046] In some embodiments, as Figure 12 shown, the coil spring fixing cover is designed with a buckle, and can fix the coil spring by cooperating with the pin fixing bracket to prevent the coil spring from slipping out.
