[0033] The wearable device 100 and the control method of the wearable device 100 according to embodiments of the present application will be described below in conjunction with Figures 1 to 13

[0034] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the wearable device 100 according to some embodiments of the present application comprises: a device body 110; a first connecting band 120, a first end of the first connecting band 120 being connected to a first side of the device body 110; a second connecting band 130, a first end of the second connecting band 130 being connected to a second side of the device body 110; a limiting structure 140, the limiting structure 140 comprising an electro- shape-changing member, the electro- shape-changing member being connected to a second end of the first connecting band 120, the electro- shape-changing member being electrically connected to the device body 110, the electro- shape-changing member being capable of switching between an unfolded state and a folded state in the case of receiving a control signal of the device body 110; when the electro- shape-changing member is in the folded state, the electro- shape-changing member locks the first connecting band 120 and the second connecting band 130; when the electro- shape-changing member is in the unfolded state, the electro- shape-changing member releases the movement restriction of the second connecting band 130, and the second connecting band 130 can be separated from the first connecting band 120.​

[0035] In this embodiment, the wearable device 100 comprises a device body 110, a first connecting band 120, a second connecting band 130, and a limiting structure 140. The limiting structure 140 comprises an electro-active shape change member. The electro-active shape change member is connected to the second end of the first connecting band 120.

[0036] Specifically, the user wears the wearable device 100, the device body 110 detects the wearing state of the wearable device 100, and in the case that the wearing state is to be worn, the device body 110 sends a first control signal to the limiting structure 140 to control the electro-active shape change member of the limiting structure 140 to deform to a folded state to lock the first connecting band 120 and the second connecting band 130.

[0037] It can be understood that the electro-active shape change member is connected to the first connecting band 120, that is, the first connecting band 120 serves as a mounting carrier of the electro-active shape change member and has the function of mounting and fixing the electro-active shape change member. In the folded state, the electro-active shape change member locks the first connecting band 120 and the second connecting band 130. Therefore, the connection of the first connecting band 120 and the second connecting band 130 is achieved, and the function of locking the connecting bands of the wearable device 100 is achieved to meet the wearing requirements of the wearable device 100.

[0038] Specifically, when it is necessary to unlock the connecting bands of the wearable device 100, the device body 110 detects that the wearing state of the wearable device 100 is to be removed, and the device body 110 sends a second control signal to the limiting structure 140 to control the electro-active shape change member to deform to an unfolded state to remove the movement restriction on the second connecting band 130. At this time, the second connecting band 130 can be separated from the first connecting band 120.

[0039] That is, the device body 110 can control the limiting structure 140 to work to change the working state (such as the unfolded state and the folded state) of the electro-active shape change member to meet the use requirements of wearing and disassembling the wearable device 100. This setting eliminates the operation of manually locking and unlocking the connecting bands of the wearable device 100, frees the user's hands, realizes the automatic wearing and disassembling of the wearable device 100, improves the intelligent degree of the product, and simplifies the user's operation.

[0040] Specifically, the voltages of the first control signal and the second control signal are different.

[0041] Optionally, the user can trigger the function button of the device body 110, and the device body 110 detects the wearing state of the wearable device 100 to be worn or to be removed.

[0042] Optionally, the device body 110 detects that the wearable device 100 is in a state of being worn or being unworn when the sensor of the device body 110 detects a user-specific arm action.

[0043] In some embodiments, the electro- morphing member includes at least two electro- morphing portions, each of which is electrically connected to the device body 110, and each of which is capable of switching between an unfolded state and a folded state.

[0044] In this embodiment, the electro- morphing member includes at least two electro- morphing portions, any of which is electrically connected to the device body 110. The device body 110 is capable of controlling each electro- morphing portion to switch between states, such as from an unfolded state to a folded state, or from a folded state to an unfolded state.

[0045] It can be understood that the wearable device 100 further includes at least two flexible circuit boards. Each flexible circuit board is electrically connected to one electro- morphing portion, and the device body 110 is electrically connected to the at least two electro- morphing portions through the at least two flexible circuit boards.

[0046] Specifically, the electro- morphing portion includes an IPMC (Ionic polymer-metal composities) morphing portion, a PVDF (polyvinylidene difluoride) morphing portion, a memory alloy morphing portion, or a shape memory polymer morphing portion.

[0047] Specifically, the wearable device 100 includes a watch, a bracelet, and the like, which are not listed one by one here.

[0048] In some embodiments, as shown in Figure 1 and Figure 2 The electro- morphing member includes a first electro- morphing portion 142 and a second electro- morphing portion 144; the first electro- morphing portion 142 and the second electro- morphing portion 144 are respectively arranged on opposite sides of the first connecting band 120.

[0049] In this embodiment, the electro- morphing member includes a first electro- morphing portion 142 and a second electro- morphing portion 144, and defines the positional relationship of the first electro- morphing portion 142, the second electro- morphing portion 144, and the first connecting band 120. Specifically, the first electro- morphing portion 142 and the second electro- morphing portion 144 are respectively arranged on opposite sides of the first connecting band 120.

[0050] That is, the first electro- morphing portion 142 is arranged on a first side of the first connecting band 120, and the second electro- morphing portion 144 is arranged on a second side of the first connecting band 120, wherein the first side and the second side are arranged opposite to each other.

[0051] The arrangement increases the contact area between the electro-active deformable member and the first connecting band 120. In the folded state, the first electro-active deformable portion 142 and the second electro-active deformable portion 144 can effectively lock the first connecting band 120 and the second connecting band 130.

[0052] In some other embodiments, the first electro-active deformable portion 142 and the second electro-active deformable portion 144 are connected to the same side of the first connecting band 120.

[0053] In some embodiments, as shown in Figure 1 and Figure 2 , when switching to the folded state, the first electro-active deformable portion 142 and the second electro-active deformable portion 144 deform to wrap around the side of the second connecting band 130 and snap onto the side of the second connecting band 130 away from the first connecting band 120; when switching to the unfolded state, the first electro-active deformable portion 142 and the second electro-active deformable portion 144 evert to the peripheral side of the second connecting band 130.

[0054] Specifically, as shown in Figure 1 and Figure 2 , when it is necessary to unlock the connecting bands of the wearable device 100, the first electro-active deformable portion 142 passes over the side of the second connecting band 130 and rests on the side of the second connecting band 130 away from the first connecting band 120, the second electro-active deformable portion 144 passes over the side of the second connecting band 130 and rests on the side of the second connecting band 130 away from the first connecting band 120, and the first electro-active deformable portion 142 and the second electro-active deformable portion 144 snap together to lock the first connecting band 120 and the second connecting band 130. In this case, Figure 1 the arrows in indicate the deformation direction of the first electro-active deformable portion 142 and the second electro-active deformable portion 144.

[0055] Figure 1 Specifically, as shown in , when it is necessary to unlock the connecting bands of the wearable device 100, the first electro-active deformable portion 142 and the second electro-active deformable portion 144 evert to the peripheral side of the second connecting band 130. In this way, the second connecting band 130 is exposed. At this time, the limiting structure 140 removes the restraint on the second connecting band 130, and the second connecting band 130 can be separated from the first connecting band 120 to achieve the purpose of disassembling the wearable device 100.

[0056] Figure 1 In some embodiments, as shown in Figure 2 , Figure 4 and Figure 7As shown, the limiting structure 140 further comprises: a first suction accessory 146 connected with the first electro-deformation part 142, the first suction accessory 146 being electrically connected with the device body 110; a second suction accessory 148 connected with the second electro-deformation part 144, the second suction accessory 148 being electrically connected with the device body 110, the first suction accessory 146 and the second suction accessory 148 being capable of switching between a first state and a second state; in the first state, the first suction accessory 146 and the second suction accessory 148 are capable of being adsorbed on the second connecting band 130; in the second state, the first suction accessory 146 and the second suction accessory 148 release the adsorption on the second connecting band 130.

[0057] In this embodiment, the limiting structure 140 further comprises the first suction accessory 146 and the second suction accessory 148. The first suction accessory 146 is connected with the first electro-deformation part 142, and the second suction accessory 148 is connected with the second electro-deformation part 144. That is, the first electro-deformation part 142 serves as a mounting carrier of the first suction accessory 146, and the first electro-deformation part 142 has the function of mounting and fixing the first suction accessory 146. The second electro-deformation part 144 serves as a mounting carrier of the second suction accessory 148, and the second electro-deformation part 144 has the function of mounting and fixing the second suction accessory 148.

[0058] In this way, when the first electro-deformation part 142 deforms to the folded state, the first suction accessory 146 is driven by the first electro-deformation part 142 to move to the side of the second connecting band 130 away from the first connecting band 120. When the first electro-deformation part 142 deforms to the unfolded state, the first suction accessory 146 is driven by the first electro-deformation part 142 to move to the circumferential side of the second connecting band 130.

[0059] In this way, when the second electro-deformation part 144 deforms to the folded state, the second suction accessory 148 is driven by the second electro-deformation part 144 to move to the side of the second connecting band 130 away from the first connecting band 120. When the second electro-deformation part 144 deforms to the unfolded state, the second suction accessory 148 is driven by the second electro-deformation part 144 to move to the circumferential side of the second connecting band 130.

[0060] Further, the first suction accessory 146 is electrically connected with the device body 110, and the second suction accessory 148 is electrically connected with the device body 110. The device body 110 controls the first suction accessory 146 and the second suction accessory 148 to switch between the first state and the second state.

[0061] Specifically, the user wears the wearable device 100, the device body 110 detects the wearing state of the wearable device 100, and in the case of the wearing state being to be worn, the device body 110 sends a first control signal to the limiting structure 140 to control the electro-deformation member of the limiting structure 140 to deform to a folded state to lock the first connecting band 120 and the second connecting band 130. The device body 110 sends a sixth control signal to the limiting structure 140 to control the first suction accessory 146 and the second suction accessory 148 to be in a first state, and in the first state, the first suction accessory 146 and the second suction accessory 148 are attached to each other with the second connecting band 130. The first suction accessory 146 and the second suction accessory 148 work with an internal current, and the first suction accessory 146 and the second suction accessory 148 have a suction effect on the second connecting band 130. So that the first connecting band 120 and the second connecting band 130 are tightly fixed. Wherein, Figure 7 The arrow in the figure indicates the direction of the force between the suction accessory and the second connecting band 130.

[0062] Specifically, when it is necessary to unlock the connecting band of the wearable device 100, the device body 110 detects that the wearing state of the wearable device 100 is to be removed, and the device body 110 sends a second control signal to the limiting structure 140 to control the first electro-deformation part 142 and the second electro-deformation part 144 to deform to an unfolded state to remove the movement restriction on the second connecting band 130. The device body 110 sends a seventh control signal to the limiting structure 140 to control the first suction accessory 146 and the second suction accessory 148 to be powered off, and the suction force between the first suction accessory 146 and the second suction accessory 148 and the second connecting band 130 disappears. At this time, the second connecting band 130 can be separated from the first connecting band 120 to unlock the first connecting band 120 and the second connecting band 130.

[0063] The first electro-deformation part 142, the second electro-deformation part 144, the first suction accessory 146 and the second suction accessory 148 cooperate to enhance the locking force of the first connecting band 120 and the second connecting band 130, realize the limiting of the limiting structure 140 to the second connecting band 130, and avoid the disconnection of the second connecting band 130 from the first connecting band 120.

[0064] That is, the device body 110 can control the limiting structure 140 to work to change the working state (such as the unfolded state and the folded state) of the first electro-deformation part 142 and the second electro-deformation part 144, and change the working state (such as the first state and the second state) of the first suction accessory 146 and the second suction accessory 148 to meet the use demand of wearing and disassembling the wearable device 100. Realize the automatic wearing and disassembling of the wearable device 100, improve the intelligent degree of the product and simplify the user operation.

[0065] Specifically, the first suction member 146 comprises a first electrostatic suction member, and the second suction member 148 comprises a second electrostatic suction member.

[0066] In some embodiments, as shown in Figure 1 , Figure 2 , the first electrostatic suction member and the second electrostatic suction member each comprise: a connecting member 150, a first end of the connecting member 150 being used to connect the first electroactive deformation part 142 and the second electroactive deformation part 144; and a suction disc 152, the suction disc 152 being connected to a second end of the connecting member 150, and the suction disc 152 being used to suck a side of the second connecting band 130 away from the first connecting band 120.

[0067] In this embodiment, the first suction member 146 comprises the connecting member 150 and the suction disc 152, and the connecting member 150 is connected between the suction disc 152 and the first electroactive deformation part 142. The second suction member 148 comprises the connecting member 150 and the suction disc 152, and the connecting member 150 is connected between the suction disc 152 and the second electroactive deformation part 144. The suction disc 152 is used to suck the second connecting band 130.

[0068] Specifically, along a radial direction of the suction disc 152, a width of the connecting member 150 is less than a radius of the suction disc 152. This arrangement can ensure the suction area of the suction disc 152 and the second connecting band 130, and also can not occupy too much space of the first suction member 146 and the second suction member 148.

[0069] Specifically, a first flexible circuit board arranged in the first connecting band 120 is electrically connected to the suction disc 152 of the first suction member 146, and a second flexible circuit board arranged in the first connecting band 120 is electrically connected to the suction disc 152 of the second suction member 148.

[0070] Specifically, the connecting member 150 comprises a connecting rod, a connecting column, etc., which are not listed one by one here.

[0071] In some embodiments, as shown in Figure 4 , Figure 5 and Figure 6 , the wearable device 100 further comprises: a first electrode part 160 arranged in the first connecting band 120, the first electrode part 160 being electrically connected to the device main body 110; and a second electrode part 170 arranged in the second connecting band 130, the second electrode part 170 being electrically connected to the device main body 110; the first electrode part 160 and the second electrode part 170 cooperating with each other to adjust the size of the circumference enclosed by the first connecting band 120 and the second connecting band 130.

[0072] In this embodiment, the wearable device 100 comprises a first electrode part 160 and a second electrode part 170, the first electrode part 160 is arranged on the first connecting band 120, the second electrode part 170 is arranged on the second connecting band 130, the first connecting band 120 has the function of mounting and fixing the first electrode part 160, and the second connecting band 130 has the function of mounting and fixing the second electrode part 170.

[0073] Specifically, the first electrode part 160 and the second electrode part 170 are electrically connected with the device main body 110.

[0074] Specifically, when the device main body 110 inputs a first current to the first electrode part 160 and a second current to the second electrode part 170, the phases of the first current and the second current are different, the first electrode part 160 and the second electrode part 170 generate a mutual force, which drives the first connecting band 120 and the second connecting band 130 to move towards each other or move away from each other, so as to adjust the size of the circumference enclosed by the first connecting band 120 and the second connecting band 130.

[0075] Specifically, when the user wears the wearable device 100, the device main body 110 controls the first electro-deformation part 142 and the second electro-deformation part 144 to deform to the folded state, and then controls the first electrode part 160 and the second electrode part 170 to adjust the positional relationship between the first connecting band 120 and the second connecting band 130 according to the size of the user's arm, so as to adaptively adjust the tightness of the user wearing the wearable device 100, and then controls the first suction part 146 and the second suction part 148 to be in the first state, so as to lock the second connecting band 130.

[0076] In the case of entering the motion state from the resting state, the device main body 110 sends a third control signal to the first electrode part 160 and the second electrode part 170 of the wearable device 100, so as to control the first electrode part 160 and the second electrode part 170 to move towards each other, so as to tighten the connecting band of the wearable device 100.

[0077] In the case of entering the sleep state, the device main body 110 sends a fourth control signal to the first electrode part 160 and the second electrode part 170, so as to control the first electrode part 160 and the second electrode part 170 to move away from each other, so as to loosen the connecting band of the wearable device 100, and improve the sleep comfort.

[0078] In the case of detecting the user's vital data (such as measuring blood pressure), the device main body 110 sends a fifth control signal to the first electrode part 160 and the second electrode part 170, so as to control the first electrode part 160 and the second electrode part 170 to move towards each other first and then move away from each other. The device main body 110 can utilize the stepless movement characteristics of the first electrode part 160 and the second electrode part 170 to realize accurate adjustment of the tightness of the connecting band.

[0079] The vital sign data of the user further includes body temperature, heartbeat, and the like, which are not listed one by one herein.

[0080] It can be understood that the first electro-deformation part 142, the second electro-deformation part 144, the first suction accessory 146, the second suction accessory 148, the first electrode part 160, and the second electrode part 170 are flexible members and can realize free deformation to meet the use requirements of different users.

[0081] In some embodiments, the first electrode part 160 and the second electrode part 170 are both comb-shaped; the device body 110 is configured to adjust the phases of the currents flowing through the first electrode part 160 and the second electrode part 170 to drive the first connecting band 120 and the second connecting band 130 to move towards each other or move away from each other, respectively.

[0082] In this embodiment, the structure of the first electrode part 160 and the second electrode part 170 is further limited, such that the first electrode part 160 and the second electrode part 170 are both comb-shaped.

[0083] The device body 110 outputs a multi-phase alternating sinusoidal wave current to the first electrode part 160 and the second electrode part 170. The sinusoidal waves applied to the first electrode part 160 and the second electrode part 170 are at different phases, and by changing the phases, the direction of the relative movement of the first electrode part 160 and the second electrode part 170 can be changed to meet the use requirements of the first connecting band 120 and the second connecting band 130 moving towards each other or moving away from each other. To achieve the purpose of automatically adjusting the tightness of the connecting bands of the wearable device 100.

[0084] Specifically, Figure 6 The arrow in the figure indicates the movement direction of the second connecting band 130 provided with the second electrode part 170. Figure 4 The arrows in the figure indicate the movement directions of the first connecting band 120 and the second connecting band 130.

[0085] In some embodiments, as shown in Figure 5 The first electrode part 160 is arranged along the length direction of the first connecting band 120; and the second electrode part 170 is arranged along the length direction of the second connecting band 130.

[0086] In this embodiment, the cooperation structure of the first connecting band 120, the second connecting band 130, the first electrode part 160, the second electrode part 170, and the limiting structure 140 is further limited.

[0087] Specifically, the first electrode portion 160 extends along the length direction of the first connecting band 120 from the end of the first connecting band 120 away from the device body 110, and the second electrode portion 170 extends along the length direction of the second connecting band 130 from the end of the second connecting band 130 away from the device body 110. That is, the first electrode portion 160 is located at the end of the first connecting band 120, and the second electrode portion 170 is located at the end of the second connecting band 130. This arrangement is more conducive to adjusting the size of the circumference enclosed by the first connecting band 120 and the second connecting band 130.

[0088] In some embodiments, as shown in FIG. 1, the first electrode portion 160 is arranged corresponding to the limiting structure 140, that is, the first electrode portion 160 and the limiting structure 140 are both located at the end of the first connecting band 120. In this way, it is more conducive to the locking and unlocking of the connecting bands of the wearable device 100.

[0089] In some embodiments, as shown in FIG. 1, the first connecting band 120, the first electro-deformation portion 142, the second electro-deformation portion 144, the first suction accessory 146, and the second suction accessory 148 are integrally formed. Figure 3

[0090] In this embodiment, the first connecting band 120, the first electro-deformation portion 142, the second electro-deformation portion 144, the first suction accessory 146, and the second suction accessory 148 are integrally formed. This structure arrangement simplifies the forming process of the first connecting band 120, the first electro-deformation portion 142, the second electro-deformation portion 144, the first suction accessory 146, and the second suction accessory 148, which is conducive to improving the processing efficiency of the product. In addition, the integrally formed first connecting band 120, first electro-deformation portion 142, second electro-deformation portion 144, first suction accessory 146, and second suction accessory 148 can ensure the dimensional accuracy of the product.

[0091] In some embodiments, as shown in FIG. 1, the first electro-deformation portion 142 is connected to the first side wall of the first connecting band 120; and the second electro-deformation portion 144 is connected to the second side wall of the first connecting band 120. Figure 3

[0092] In this embodiment, the cooperation structure of the first electro-deformation portion 142, the second electro-deformation portion 144, the first connecting band 120, and the second connecting band 130 is further limited. Specifically, the first connecting band 120 has oppositely arranged first and second side walls. The first electro-deformation portion 142 is connected to the first side wall of the first connecting band 120, and the second electro-deformation portion 144 is connected to the second side wall of the first connecting band 120, that is, the first connecting band 120 is connected between the first electro-deformation portion 142 and the second electro-deformation portion 144. ​​

[0093] Specifically, the first electrodeformable portion 142 is bonded to the first connecting strip 120 . The second electrodeformable portion 144 is bonded to the first connecting strip 120 .

[0094] In some other embodiments, at least one of the first electrodeformable portion 142 and the second electrodeformable portion 144 is inserted into the first connecting strip 120 .

[0095] The present application simultaneously realizes automatic tightening of the connecting belt, stepless adjustment of the tightening degree, firm fixation and no pain on the wrist.

[0096] like Figure 1 and Figure 2 As shown, the wearable device 100 includes a device body 110, which is the main body of the wearable device 100 and is responsible for providing control signals to control the movement of the first connecting band 120 and the second connecting band 130. The first connecting band 120 is connected to a limiting structure 140.

[0097] The limiting structure 140 includes a first electrodeformable portion 142 and a second electrodeformable portion 144. The first electrodeformable portion 142 and the second electrodeformable portion 144 are fixedly connected to the first connecting band 120 (they can be embedded in the injection molded part or glued, etc., and fixed and fastened). When the wearable device 100 is working, the first electrodeformable portion 142 and the second electrodeformable portion 144 are in a bent and folded state, wrapped around the second connecting band 130 (the location where the second connecting band 130 is fixed will vary depending on the thickness of the user's wrist).

[0098] The first electrodeformable portion 142 is fixedly connected to the first adsorption member 146 , and the second electrodeformable portion 144 is fixedly connected to the second adsorption member 148 .

[0099] The first electrodeformable portion 142 and the second electrodeformable portion 144 are made of IPMC (ion-exchange polymeric metal material). When the device body 110 outputs different DC voltage control signals, the IPMC switches between a straight and a curved state. When the user needs to untie the connecting strap, the IPMC unfolds to a straight state, facilitating the separation of the two connecting straps. When the user is using the wearable device 100 normally, the IPMC is in a curved and folded state, buckled on the second connecting strap 130, acting as a limiter to ensure that the two connecting straps are in an overlapping position.

[0100] The first connecting band 120 is arranged with a first electrode part 160, and the second connecting band 130 is arranged with a second electrode part 170. The first electrode part 160 and the second electrode part 170 are both comb-shaped, and the first electrode part 160 and the second electrode part 170 form an electrostatic motor. When the device main body 110 outputs a specific alternating voltage waveform to the comb-shaped electrodes (in general, the voltage here is a multi-phase alternating sine wave, and the sine waves applied to the two electrode parts are in different phases). Changing the phase can change the direction of the relative motion of the two electrode parts.

[0101] The comb-shaped electrodes on the two connecting bands generate interaction forces, driving the two connecting bands to move towards each other (i.e., tightening the connecting bands), or moving away from each other (i.e., loosening the connecting bands). When the use scenario changes, for example, from a resting state to a motion state, the device main body 110 recognizes the motion scenario and sends an electrical signal to tighten the connecting bands. When the user enters a sleep state, the device main body 110 can also control the connecting bands to loosen, improving sleep comfort. For scenarios such as measuring blood pressure, which require a high degree of tightness of the connecting bands, the device main body 110 can use the stepless motion characteristics of the first electrode part 160 and the second electrode part 170 to achieve precise adjustment of the tightness.

[0102] The first suction accessory 146 is connected to the first electro-deformation part 142, and the second suction accessory 148 is connected to the second electro-deformation part 144. In the normal working state of the wearable device 100, the first suction accessory 146 and the second suction accessory 148 are in close contact with the second connecting band 130. When the first suction accessory 146 and the second suction accessory 148 are working, an electric current is passed through the inside, at which time the first suction accessory 146 and the second suction accessory 148 have a suction effect on the second connecting band 130, thereby ensuring the close fixing between the two connecting bands. When the user needs to loosen the connecting bands, the first suction accessory 146 and the second suction accessory 148 are powered off, and the suction force between the first suction accessory 146, the second suction accessory 148 and the second connecting band 130 disappears, facilitating the separation of the two connecting bands.

[0103] The embodiment of the present application provides a control method of a wearable device, as shown in the figure, the control method of the wearable device comprises the following steps: Figure 8 The control method of the wearable device comprises the following steps:

[0104] Step 802, detecting the wearing state of the wearable device;

[0105] Step 804, in the case that the wearing state is to be worn, the device main body of the wearable device sends a first control signal to the limiting structure of the wearable device, to control the electro-deformation part of the limiting structure to switch to a folded state, to lock the first connecting band and the second connecting band of the wearable device;

[0106] At step 806, when the wearing state of the wearable device is to be removed, the device main body sends a second control signal to the limiting structure to control the electro-deformation member to switch to the unfolded state to remove the movement restriction on the second connecting band, so that the second connecting band can be separated from the first connecting band.

[0107] Specifically, the user wears the wearable device, and the device main body detects the wearing state of the wearable device. When the wearing state of the wearable device is to be worn, the device main body sends a first control signal to the limiting structure to control the electro-deformation member of the limiting structure to deform to the folded state to lock the first connecting band and the second connecting band.

[0108] It can be understood that the electro-deformation member is connected with the first connecting band, that is, the first connecting band serves as a mounting carrier of the electro-deformation member and has the function of mounting and fixing the electro-deformation member. In the folded state, the electro-deformation member locks the first connecting band and the second connecting band. Therefore, the connection of the first connecting band and the second connecting band is achieved, and the function of locking the connecting band of the wearable device is achieved to meet the wearing requirement of the wearable device.

[0109] Specifically, when it is required to unlock the connecting band of the wearable device, the device main body detects that the wearing state of the wearable device is to be removed, and the device main body sends a second control signal to the limiting structure to control the electro-deformation member to deform to the unfolded state to remove the movement restriction on the second connecting band. At this time, the second connecting band can be separated from the first connecting band.

[0110] That is, the device main body can control the limiting structure to work to change the working state (such as the unfolded state and the folded state) of the electro-deformation member to meet the use requirement of wearing and disassembling the wearable device. This setting eliminates the operation of manually locking and unlocking the connecting band of the wearable device, frees the hands of the user, realizes the automatic wearing and disassembling of the wearable device, improves the intelligent degree of the product, and simplifies the operation of the user.

[0111] Specifically, the voltage of the first control signal is different from that of the second control signal.

[0112] Optionally, the user can trigger the function button of the device main body, and the device main body detects that the wearing state of the wearable device is to be worn or to be removed.

[0113] Optionally, when the sensor of the device main body detects a specific arm movement of the user, the device main body detects that the wearing state of the wearable device is to be worn or to be removed.

[0114] Specifically, the device body outputs a first direct current voltage to the first and second electro- morphic parts of the limiting structure, the first and second electro-morphic parts deform to a folded state to lock the second connecting band. The device body outputs a second direct current voltage to the first and second electro-morphic parts of the limiting structure, the first and second electro-morphic parts deform to an unfolded state to release the movement restriction on the second connecting band, at this time, the second connecting band can be separated from the first connecting band. The first and second direct current voltages are different.

[0115] In some embodiments, after the electro-morphic part of the limiting structure is switched to the folded state, the method further comprises: detecting a use scenario of the wearable device; in the case of entering a motion state from a resting state, the device body sends a third control signal to the first and second electrode parts of the wearable device to control the first and second electrode parts to move towards each other; in the case of entering a sleep state, the device body sends a fourth control signal to the first and second electrode parts to control the first and second electrode parts to move away from each other; in the case of detecting the user's vital data, the device body sends a fifth control signal to the first and second electrode parts to control the first and second electrode parts to move towards each other first and then move away from each other.

[0116] In this embodiment, the wearable device comprises the first and second electrode parts, the first electrode part is arranged on the first connecting band, and the second electrode part is arranged on the second connecting band. The first connecting band has the function of mounting and fixing the first electrode part, and the second connecting band has the function of mounting and fixing the second electrode part.

[0117] Specifically, the first and second electrode parts are electrically connected with the device body.

[0118] Specifically, when the device body inputs a first current to the first electrode part and a second current to the second electrode part, the phases of the first and second currents are different, the first and second electrode parts generate a mutual force to drive the first and second connecting bands to move towards each other or move away from each other, so as to adjust the size of the circumference enclosed by the first and second connecting bands.

[0119] In the case of entering a motion state from a resting state, the device body sends a third control signal to the first and second electrode parts of the wearable device to control the first and second electrode parts to move towards each other, so that the connecting band of the wearable device is tightened.

[0120] In the case of entering a sleep state, the device body sends a fourth control signal to the first and second electrode parts to control the first and second electrode parts to move away from each other, so as to control the connecting band of the wearable device to be relaxed and improve the sleep comfort.

[0121] In the case where the use scenario is to detect the user's vital data (e.g., measure blood pressure), the device body sends a fifth control signal to the first electrode part and the second electrode part to control the first electrode part and the second electrode part to move towards each other first and then move away from each other. The device body can utilize the stepless movement characteristics of the first electrode part and the second electrode part to accurately adjust the tightness of the connecting band.

[0122] The user's vital data further includes body temperature, heartbeat, and the like, which are not listed here.

[0123] In some embodiments, after the electro-deformation part of the limiting structure is switched to the folded state, the device body further sends a sixth control signal to the limiting structure to control the first electrostatic adsorption part and the second electrostatic adsorption part of the limiting structure to adsorb the second connecting band of the wearable device.

[0124] In some embodiments, before the electro-deformation part is switched to the unfolded state, the device body further sends a seventh control signal to the limiting structure to control the first electrostatic adsorption part and the second electrostatic adsorption part of the limiting structure to stop working.

[0125] In this embodiment, the first adsorption part is electrically connected to the device body, and the second adsorption part is electrically connected to the device body. When the limiting structure is triggered, the first adsorption part and the second adsorption part can be switched between the first state and the second state.

[0126] Specifically, the user wears the wearable device, and the device body detects the wearing state of the wearable device. In the case where the wearing state is to be worn, the device body sends a first control signal to the limiting structure to control the electro-deformation part of the limiting structure to deform to a folded state to lock the first connecting band and the second connecting band. The device body sends a sixth control signal to the limiting structure to control the first adsorption part and the second adsorption part to be in a first state. In the first state, the first adsorption part and the second adsorption part are in close contact with the second connecting band. The first adsorption part and the second adsorption part have an adsorption effect on the second connecting band when they are working. The first connecting band and the second connecting band are tightly fixed.

[0127] Specifically, when it is necessary to unlock the connecting band of the wearable device, the device body detects that the wearing state of the wearable device is to be removed. The device body sends a second control signal to the limiting structure to control the first electro-deformation part and the second electro-deformation part to deform to an unfolded state to release the movement restriction on the second connecting band. The device body sends a seventh control signal to the limiting structure to control the first adsorption part and the second adsorption part to be powered off, and the adsorption force between the first adsorption part and the second adsorption part and the second connecting band disappears. At this time, the second connecting band can be separated from the first connecting band.

[0128] The first electro-morphing part, the second electro-morphing part, the first suction member and the second suction member cooperate to enhance the locking force of the first connecting band and the second connecting band, and the limiting structure can limit the second connecting band in multiple directions and multiple angles, so that the second connecting band can be prevented from being separated from the first connecting band.

[0129] That is, the device body can control the limiting structure to work to change the working states (such as the unfolded state and the folded state) of the first electro-morphing part and the second electro-morphing part, and change the working states (such as the first state and the second state) of the first suction member and the second suction member, so as to meet the use requirements of wearing and disassembling the wearable device. The automatic wearing and disassembling of the wearable device are realized, the intelligent degree of the product is improved, and the user operation is simplified.

[0130] In some embodiments, after detecting the use scenario of the wearable device, the device body further sends an eighth control signal to the limiting structure to control the first electrostatic suction member and the second electrostatic suction member of the limiting structure to stop working when the use scenario changes.

[0131] In this embodiment, when the use scenario changes, the device body sends an eighth control signal to the limiting structure to control the first electrostatic suction member and the second electrostatic suction member to stop working, so as to subsequently adjust the cooperation size of the first connecting band and the second connecting band to adaptively adjust the tightness of the user wearing the wearable device.

[0132] As shown in Figure 9 The present application embodiment provides a control device 900 of a wearable device, which comprises:

[0133] A detection module 902 is configured to detect a wearing state of the wearable device.

[0134] An execution module 904 is configured to, when the wearing state is to be worn, send a first control signal to a limiting structure of the wearable device through a device body of the wearable device to control an electro-morphing part of the limiting structure to switch to a folded state to lock a first connecting band and a second connecting band of the wearable device; and when the wearing state is to be disassembled, send a second control signal to the limiting structure through the device body to control the electro-morphing part to switch to an unfolded state to release the movement restriction on the second connecting band, so that the second connecting band can be separated from the first connecting band.

[0135] In this embodiment, the control device 900 of the wearable device comprises the detection module 902 and the execution module 904.

[0136] Specifically, the user wears the wearable device, the detection module detects the wearing state of the wearable device, and in the case that the wearing state is to be worn, the execution module sends a first control signal to the limiting structure through the device main body to control the electro-deformation piece of the limiting structure to deform to a folded state to lock the first connecting band and the second connecting band.

[0137] It can be understood that the electro-deformation piece is connected with the first connecting band, that is, the first connecting band serves as a mounting carrier of the electro-deformation piece and has the function of mounting and fixing the electro-deformation piece. In the folded state, the electro-deformation piece locks the first connecting band and the second connecting band. Therefore, the connection of the first connecting band and the second connecting band is achieved, and the function of locking the connecting band of the wearable device is achieved to meet the wearing requirement of the wearable device.

[0138] Specifically, when it is required to unlock the connecting band of the wearable device, the device main body detects that the wearing state of the wearable device is to be removed, and the device main body sends a second control signal to the limiting structure to control the electro-deformation piece to deform to an unfolded state to remove the movement restriction on the second connecting band. At this time, the second connecting band can be separated from the first connecting band.

[0139] That is, the device main body can control the limiting structure to work to change the working state (such as the unfolded state and the folded state) of the electro-deformation piece to meet the use requirement of wearing and disassembling the wearable device. This setting eliminates the operation of manually locking and unlocking the connecting band of the wearable device, frees the user's hands, realizes the automatic wearing and disassembling of the wearable device, improves the intelligent degree of the product, and simplifies the user operation.

[0140] In some embodiments, the detection module 902 is further configured to detect a use scenario of the wearable device, and the execution module 904 is further configured to, in the case that the use scenario is to enter a motion state from a resting state, send a third control signal to the first electrode part and the second electrode part of the wearable device through the device main body to control the first electrode part and the second electrode part to move towards each other, in the case that the use scenario is to enter a sleep state, send a fourth control signal to the first electrode part and the second electrode part through the device main body to control the first electrode part and the second electrode part to move away from each other, and in the case that the use scenario is to detect the vital sign data of the user, send a fifth control signal to the first electrode part and the second electrode part through the device main body to control the first electrode part and the second electrode part to first move towards each other and then move away from each other.

[0141] In this embodiment, the wearable device includes the first electrode part and the second electrode part, the first electrode part is arranged on the first connecting band, and the second electrode part is arranged on the second connecting band. The first connecting band has the function of mounting and fixing the first electrode part, and the second connecting band has the function of mounting and fixing the second electrode part.

[0142] Specifically, the first electrode part and the second electrode part are both electrically connected with the device body.

[0143] Specifically, when the device body inputs a first current to the first electrode part and a second current to the second electrode part, the phases of the first current and the second current are different, the first electrode part and the second electrode part generate an interaction force, and the first connecting band and the second connecting band move towards each other or move away from each other to adjust the size of the circumference enclosed by the first connecting band and the second connecting band.

[0144] In the case of a use scenario of entering a motion state from a resting state, the device body sends a third control signal to the first electrode part and the second electrode part of the wearable device to control the first electrode part and the second electrode part to move towards each other, so that the connecting band of the wearable device is tightened.

[0145] In the case of a use scenario of entering a sleep state, the device body sends a fourth control signal to the first electrode part and the second electrode part to control the first electrode part and the second electrode part to move away from each other, so that the connecting band of the wearable device is loosened, and the sleep comfort is improved.

[0146] In the case of a use scenario of detecting the user's vital data (such as measuring blood pressure), the device body sends a fifth control signal to the first electrode part and the second electrode part to control the first electrode part and the second electrode part to move towards each other first and then move away from each other. The device body can utilize the stepless movement characteristics of the first electrode part and the second electrode part to achieve accurate adjustment of the tightness of the connecting band.

[0147] In some embodiments, the execution module 904 is further configured to send a sixth control signal to the limiting structure by the device body to control the first electrostatic adsorption part and the second electrostatic adsorption part of the limiting structure to adsorb the second connecting band of the wearable device, and to send a seventh control signal to the limiting structure by the device body to control the first electrostatic adsorption part and the second electrostatic adsorption part of the limiting structure to stop working.

[0148] In this embodiment, the first adsorption part is electrically connected with the device body, and the second adsorption part is electrically connected with the device body. When the limiting structure is triggered, the first adsorption part and the second adsorption part can be switched between the first state and the second state.

[0149] Specifically, the user wears the wearable device, the device body detects the wearing state of the wearable device, in the case of wearing state being to be worn, the device body sends a first control signal to the limiting structure to control the electro-deformation part of the limiting structure to deform to a folded state to lock the first connecting band and the second connecting band. The device body sends a sixth control signal to the limiting structure to control the first suction accessory and the second suction accessory to be in a first state, in the first state, the first suction accessory and the second suction accessory are attached to each other with the second connecting band. The first suction accessory and the second suction accessory work with internal current, and the first suction accessory and the second suction accessory have a suction effect on the second connecting band. So that the first connecting band and the second connecting band are tightly fixed.

[0150] Specifically, when the connecting band of the wearable device needs to be unlocked, the device body detects that the wearing state of the wearable device is to be removed, and the device body sends a second control signal to the limiting structure to control the first electro-deformation part and the second electro-deformation part to deform to an unfolded state to remove the movement restriction on the second connecting band. The device body sends a seventh control signal to the limiting structure to control the first suction accessory and the second suction accessory to be powered off, and the suction force between the first suction accessory and the second suction accessory and the second connecting band disappears. At this time, the second connecting band can be separated from the first connecting band.

[0151] The first electro-deformation part, the second electro-deformation part, the first suction accessory and the second suction accessory cooperate to enhance the locking force of the first connecting band and the second connecting band, realize the limiting effect of the limiting structure on the second connecting band in multiple directions and multiple angles, and avoid the separation of the second connecting band from the first connecting band.

[0152] That is, the device body can control the limiting structure to work to change the working state (such as the unfolded state and the folded state) of the first electro-deformation part and the second electro-deformation part, and change the working state (such as the first state and the second state) of the first suction accessory and the second suction accessory to meet the use demand of wearing and disassembling the wearable device. The automatic wearing and disassembling of the wearable device is realized, the intelligent degree of the product is improved, and the user operation is simplified.

[0153] In some embodiments, the execution module 904 is further configured to send an eighth control signal to the limiting structure through the device body to control the first electrostatic suction accessory and the second electrostatic suction accessory of the limiting structure to stop working when the use scene changes.

[0154] In this embodiment, when the use scene changes, the device body sends an eighth control signal to the limiting structure to control the first electrostatic suction accessory and the second electrostatic suction accessory to stop working, so as to subsequently adjust the fitting size of the first connecting band and the second connecting band to adaptively adjust the tightness of the user wearing the wearable device.

The device can be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc., and the non-mobile electronic device can be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), an ATM or a self-service machine, etc., which is not specifically limited in the embodiment of the present application.
