DETAILED DESCRIPTION

[0028] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same elements throughout the drawings, unless otherwise explicitly described. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they only represent examples of apparatuses and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0029] The watchband with a light-emitting function in the related art has certain safety hazards and poor wearing comfort. For example, the watchband in the related art includes a watchband body and a battery and an LED lamp arranged on the watchband body. The LED lamp is powered by the battery to emit light. The battery itself has a certain weight, and the compression on the user's wrist will be stronger when wearing, thereby reducing the comfort of the user when wearing. Moreover, the long-time compression of the battery in the bending state during wearing will cause certain safety hazards. If the battery is designed as an arc structure that fits the wrist, the production cost will be increased.

[0030] To solve the above technical problems, the present disclosure provides a watchband. At least one light-emitting module is arranged in the watchband body. The piezoelectric part of the light-emitting module supplies power to the light-emitting part of the light-emitting module by using the piezoelectric effect, so that the light-emitting part can emit light. In this way, instead of arranging a battery in the watchband body to achieve the light-emitting mode, not only the comfort of the user when wearing can be improved, but also the safety of the wearable device can be effectively improved. In addition, it is also helpful to reduce the production cost of the wearable device.

[0031] An example embodiment of the present disclosure provides a watchband, as shown in Figure 1 and Figure 2 The watchband 10 includes a watchband body 11 and at least one light-emitting module 12. The at least one light-emitting module 12 is arranged in the watchband body 11. For example, only one light-emitting module 12 can be arranged on the watchband body 11, or multiple light-emitting modules 12, such as two or three, can be arranged on the watchband body 11. Figure 3 or Figure 4 The light-emitting module 12 includes a light-emitting part 124 and a piezoelectric part 125. The piezoelectric part 125 is used to supply power to the light-emitting part 124 by using the piezoelectric effect, so that the light-emitting part 124 can emit light. It can be understood that the piezoelectric effect refers to the polarization phenomenon inside some dielectrics when they are deformed in a certain direction under the action of external force, and at the same time, positive and negative charges appear on the two opposite surfaces. When the watchband 10 is in the wearing state, the watchband body 11 will cause compression to the wrist 20, thereby generating pressure, so that there will always be a potential difference on the piezoelectric part 125 on the watchband body 11, thereby continuously supplying power to the light-emitting part 124, so that the light-emitting part 124 can continuously emit light. When the watchband 10 is in the non-wearing state, the piezoelectric part 125 will return to the uncharged state, and the light-emitting part 124 will not emit light.

[0032] With such a setting form, instead of setting a battery in the watchband body 11 to realize the light-emitting mode, not only the comfort of the user when wearing can be improved, but also the safety of the wearable device 30 can be effectively improved, and the production cost of the wearable device 30 can be reduced. In addition, the piezoelectric effect is used to supply power to the light-emitting part 124, which not only reduces the processing difficulty of the watchband 10, but also reduces the overall energy consumption of the wearable device 30, since the light-emitting part 124 can realize the light-emitting function without additional power supply.

[0033] In this embodiment, by utilizing the piezoelectric effect to make the watchband 10 have a light-emitting function, it can play a warning role during outdoor activities such as running and cycling. Since no additional power supply is required, the light-emitting function of the watchband 10 can also play a role in warning for help when the mobile phone, watch, or the like is out of power or has poor signal. The light-emitting mode of the light-emitting part 124 can also be programmed to realize unified control of the light-emitting part 124 during live activities such as parties and concerts, so as to increase the atmosphere of the live activities.

[0034] In combination Figure 3 or Figure 4 In an embodiment, the piezoelectric part 125 includes a piezoelectric material layer 1251 and a conductive layer 1252. The piezoelectric material layer 1251 may, for example, be a piezoelectric single crystal material, a piezoelectric ceramic material, or a structure made of piezoelectric material. The conductive layer 1252 may, for example, be a flexible printed circuit (FPC), a conductive metal, or a conductive particle. The conductive layer 1252 is electrically connected to the piezoelectric material layer 1251 and the light-emitting part 124, respectively, so that the piezoelectric material layer 1251 can supply power to the light-emitting part 124. In this way, the structure of the piezoelectric part 125 is simple, which is convenient for production and processing.

[0035] In an embodiment, the piezoelectric material layer 1251 includes piezoelectric ceramic or piezoelectric film. It can be understood that piezoelectric ceramic is an electronic ceramic material with piezoelectric properties. Since piezoelectric ceramic has a high electromechanical coupling coefficient, the use of piezoelectric ceramic as the piezoelectric material layer 1251 can effectively improve the conversion efficiency between mechanical energy and electrical energy, thereby improving the light-emitting effect of the watchband 10. In addition, since the raw material cost of piezoelectric ceramic is low, the use of piezoelectric ceramic as the piezoelectric material layer 1251 can further reduce the production cost of the wearable device 30.

[0036] The piezoelectric film is a thin film material with piezoelectric effect, which has high flexibility and plasticity, and thus the piezoelectric film is less affected by the bending of the watchband body 11, thereby improving the reliability of the watchband 10. In addition, since the piezoelectric film is extremely light in quality, the increase in the weight of the watchband 10 is reduced, thereby further improving the wearing comfort of the wearable device 30 and enhancing the user experience.

[0037] In combination Figure 3 or Figure 4 In an embodiment, the light emitting part 124 includes a light emitting layer 1241 and a light guide layer 1242, and the light emitting layer 1241 is electrically connected with the piezoelectric part 125. Exemplarily, the light emitting layer 1241 may, for example, be an LED lamp, a new type of electronic fabric, etc. The light guide layer 1242 is used to guide the light emitted by the light emitting layer 1241. Exemplarily, the light guide layer 1242 may, for example, be a light guide plate, a light guide optical fiber, etc. In this way, the light emitting layer 1241 is powered by the piezoelectric part 125 to realize light emission, and the light emitted by the light emitting layer 1241 is guided by the light guide layer 1242 to be uniformly distributed, so that the uniformity of the light emitted by the watchband 10 can be effectively improved, and the light emitting effect of the watchband 10 is improved.

[0038] In an embodiment, the watchband body 11 includes a pressure receiving area. It should be noted that the pressure receiving area of the watchband body 11 refers to an area of the watchband body 11 that is extruded by the wrist 20 in the wearing state, and the wrist 20 forms a reaction force on the watchband body 11 so that the watchband body 11 is subjected to pressure. For example Figure 5 and Figure 6 As shown in FIGS. 17 and 18, the wrist 20 includes a dorsal side 21, a palmar side 22, a ulnar side 23, an ulnar upper side 24, an ulnar lower side 25, a radial side 26, a radial upper side 27, and a radial lower side 28. It can be seen from simulation that when the watchband 10 is in the wearing process, the palmar side 22, the ulnar side 23, and the ulnar lower side 25 have a greater compression force, and thus the palmar side 22, the ulnar side 23, and the ulnar lower side 25 are the pressure receiving areas. The light emitting module 12 is arranged in the pressure receiving area that can generate a greater compression force. On the one hand, the pressure receiving area of the watchband body 11 in the wearing state is subjected to pressure, so that the piezoelectric part 125 continuously supplies power to the light emitting layer 1241 by using the piezoelectric effect, thereby improving the light emitting effect of the watchband 10. On the other hand, the light emitting module 12 reduces the occupation of the internal space of the watchband body 11, which not only facilitates the processing of the watchband 10 and improves the production efficiency, but also reduces the overall rigidity of the watchband body 11, thereby further improving the comfort and fit of the watchband 10 when worn.

[0039] In addition, the pressure receiving area can be divided into a first area and a second area, and the bending degree of the first area is greater than that of the second area when the watchband body 11 is in a wearing state. The light-emitting layer 1241 includes at least one light-emitting element, and the at least one light-emitting element is arranged in the second area with a smaller bending degree in the pressure receiving area. Exemplarily, the light-emitting layer 1241 can have only one light-emitting element, or can have a plurality of light-emitting elements, for example, 2, 5, 8, etc., and can be arranged only in the second area with one light-emitting element, or can be arranged with a plurality of light-emitting elements, and the light-emitting element is, for example, an LED lamp. By adopting such a setting form, damage to the light-emitting element caused by the bending of the pressure receiving area can be avoided, thereby further improving the reliability of the watchband 10.

[0040] In combination Figure 3 In an embodiment, the watchband body 11 includes an inner surface 111 and an outer surface 112 opposite to each other. It should be noted that the inner surface 111 of the watchband body 11 refers to a side surface of the watchband body 11 facing the user's wrist 20 when the watchband body 11 is in a wearing state, and the surface opposite to the surface is the outer surface 112, which can be seen by the user when the watchband body 11 is in a wearing state.

[0041] Corresponding to the position of each light-emitting module 12, the outer surface 112 of the watchband body 11 is provided with a receiving groove 113, and the light-emitting module 12 is embedded in the receiving groove 113, and the light-emitting part 124 is exposed through the slot of the receiving groove 113. By such design, on the one hand, the light-emitting part 124 can emit light to the external environment while fixing each light-emitting module 12, thereby ensuring the light-emitting effect of the watchband 10. On the other hand, by arranging the receiving groove 113 on the outer surface 112 to fix the light-emitting module 12, at this time, the groove bottom of the receiving groove 113 realizes the isolation of the light-emitting module 12 and the user's wrist 20, so that while ensuring that the pressure can be transmitted to the piezoelectric material layer 1251 of the light-emitting module 12, not only the human body can be prevented from being damaged by the light-emitting module 12, thereby further improving the safety of the watchband 10, but also the liquid such as sweat and water vapor on the user's wrist 20 can be prevented from entering the light-emitting module 12 to cause damage to the light-emitting module 12, thereby further improving the reliability of the watchband 10.

[0042] In combination Figure 4In another embodiment, the watchband body 11 comprises opposite inner and outer surfaces 111 and 112. Corresponding to the position of each light-emitting module 12, the watchband body 11 is provided with a hollow structure 114 penetrating the inner and outer surfaces 111 and 112. The light-emitting module 12 is embedded in the hollow structure 114, and the piezoelectric part 125 faces the opening formed by the hollow structure 114 on the inner surface 111, and the light-emitting part 124 is exposed through the opening formed by the hollow structure 114 on the outer surface 112. With such a setting form, on the one hand, the fixation of each light-emitting module 12 is achieved while the structure of the watchband 10 is simple, facilitating production and processing. On the other hand, the light-emitting part 124 is exposed through the opening formed by the hollow structure 114 on the outer surface 112, so that the light emitted by the light-emitting part 124 can irradiate to the external environment, thereby ensuring the light-emitting effect of the watchband 10.

[0043] As shown in Figure 4 In an embodiment, when the hollow structure 114 penetrating the inner and outer surfaces 111 and 112 is arranged on the watchband body 11 to fix the light-emitting module 12 through the hollow structure 114, the watchband 10 further comprises an insulating layer 13 arranged at the opening formed by the hollow structure 114 on the inner surface 111 to insulate the light-emitting module 12 from the user's wrist 20. Exemplarily, the insulating layer 13 can be a silica gel structure, a rubber structure, or a film, fabric or the like with insulating properties. In this way, while ensuring that the pressure can be transmitted to the piezoelectric material layer 1251 of the light-emitting module 12, not only can the human body be protected from damage by the light-emitting module 12, thereby further improving the safety of the watchband 10, but also the liquid such as sweat and water vapor on the user's wrist 20 can be prevented from entering the light-emitting module 12 to cause damage to the light-emitting module 12, thereby further improving the reliability of the watchband 10.

[0044] As shown in Figure 1As shown, in an embodiment, the watchband body 11 is provided with a plurality of light-emitting modules 12, and at least two light-emitting modules 12 in the plurality of light-emitting modules 12 are electrically connected through the flexible electrical connection part. Exemplarily, only two light-emitting modules 12 in the plurality of light-emitting modules 12 can be electrically connected through the flexible electrical connection part, or all the light-emitting modules 12 in the plurality of light-emitting modules 12 can be electrically connected through the flexible electrical connection part, which is not specifically limited. With such a setting form, on the one hand, through the connection of the flexible electrical connection part, the simultaneous lighting of the at least two connected light-emitting modules 12 can be realized, so as to improve the overall lighting brightness of the watchband 10, and further improve the user's experience. On the other hand, through the connection of the flexible electrical connection part, the mutual power supply between the at least two connected light-emitting modules 12 can be realized, for example, when the piezoelectric material of one of the at least two connected light-emitting modules 12 fails, the piezoelectric material of the other connected light-emitting module 12 supplies power to the light-emitting part 124 in the light-emitting module 12 to realize the lighting of the light-emitting part 124 in the light-emitting module 12. In this way, the lighting effect of the watchband 10 can be further improved.

[0045] Exemplarily, the flexible connection part 14 can be, for example, an FPC circuit board, a copper wire or other conductive materials with bending performance.

[0046] As shown, Figure 1 As shown, in an embodiment, the watchband body 11 is provided with a plurality of wearing holes 115 which are arranged at intervals along the length direction of the watchband body 11. The wearing holes 115 can realize the wearing of the watchband 10 and the self-adjustment of the watchband 10 when worn, which will not be described in detail here.

[0047] The plurality of light-emitting modules 12 includes a first light-emitting module 121, a second light-emitting module 122 and a third light-emitting module 123. Along the width direction of the watchband body 11, the first light-emitting module 121 and the second light-emitting module 122 are respectively arranged on both sides of the wearing hole 115 and extend along the length direction of the watchband body 11. The third light-emitting module 123 is arranged on the watchband body 11 near the free end of the watchband body 11 and extends along the width direction of the watchband body 11. It should be noted that one end of the watchband body 11 is used to connect the watch of the wearable device 30, and the other end is the free end.

[0048] With such a setting form, on the one hand, the light-emitting modules 12 avoid the plurality of wearing holes 115, ensuring the wearing convenience of the watchband body 11, and avoiding damage to the light-emitting modules 12 caused by the arrangement of the wearing holes 115, thereby further improving the reliability of the watchband 10. On the other hand, the light-emitting modules 12 reduce the occupation of the internal space of the watchband body 11, which not only facilitates the processing of the watchband 10 and improves the production efficiency, but also reduces the overall stiffness of the watchband body 11, thereby further improving the comfort and fit of the watchband 10 when worn.

[0049] An example embodiment of the present disclosure provides a wearable device 30, which is exemplarily a smart watch, a smart bracelet, a watch, or the like.

[0050] As shown in Figure 1 and Figure 5 The wearable device 30 comprises the watchband 10 as described above. The watchband 10 comprises a watchband body 11 and at least one light-emitting module 12 arranged on the watchband body 11. The light-emitting module 12 comprises a light-emitting part 124 and a piezoelectric part 125 for supplying power to the light-emitting part 124 by piezoelectric effect so as to enable the light-emitting part 124 to emit light. In this way, instead of arranging a battery in the watchband body 11 to realize the light-emitting mode, not only the comfort of the user when wearing can be improved, but also the safety of the wearable device 30 can be effectively improved, and the production cost of the wearable device 30 can be reduced. In addition, the light-emitting part 124 is supplied with power by piezoelectric effect, and the light-emitting function of the light-emitting part 124 can be realized without additional power supply to the light-emitting part 124, and the overall energy consumption of the wearable device 30 can be reduced.
