[0003] The wearable device usually includes a device main body and a connecting band. The connecting band is connected with the device main body, and the device main body can be worn on the user's body through the connecting band. Moreover, the wearable device adopts a separate adjusting mechanism to adjust the effective wearing length of the connecting band to adapt to users with different body sizes and improve the wearing comfort. However, the stability of the connecting band after adjustment is poor, which leads to the change of the effective wearing length of the connecting band and further leads to the easy loosening of the wearable device. Therefore, the wearable device in the related art is also provided with a locking mechanism. After the effective wearing length of the connecting band is adjusted, the locking mechanism is used to lock the connecting band to avoid loosening of the wearable device. However, in this way, the user needs to manually operate the locking mechanism every time the wearable device is used to lock and unlock, so that the whole adjusting process is relatively complicated, which affects the use effect and reduces the user experience. SUMMARY

Meanwhile, the pressure detection element is connected with at least one of the device body and the connecting band, so that the pressure detection element can detect the pressure applied to the device body or the connecting band by the user. In the process of adjusting the connecting band, the size of the space surrounded by the connecting band and the device body changes, and the pressure value applied to the device body or the connecting band by the user also changes. The wearable device can control the driving mechanism according to the pressure value detected by the pressure detection element, so as to adjust the space surrounded by the connecting band and the device body.

In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the objects before and after it.

[0043] The wearable device and the control method thereof provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0044] Please refer to Figures 1-12 The wearable device disclosed in the embodiments of the present application comprises a device main body 100, a connecting band 200, a driving mechanism 300 and a pressure sensing device 400, wherein the device main body 100 serves as a mounting base of the connecting band 200, a first end of the connecting band 200 is connected to the device main body 100, a second end of the connecting band 200 is slidingly connected to the device main body 100, the connecting band 200 and the device main body 100 can form a space for accommodating a wearing part of a user, and the size of the space formed by the connecting band 200 and the device main body 100 changes during movement of the connecting band 200 relative to the device main body 100.

[0045] The driving mechanism 300 is connected to the second end of the connecting band 200, and the driving mechanism 300 can drive the second end of the connecting band 200 to move relative to the device main body 100. Optionally, the driving mechanism 300 can be a telescopic cylinder, one end of the telescopic cylinder is connected to the device main body 100, the other end of the telescopic cylinder is connected to the second end of the connecting band 200, and the second end of the connecting band 200 is driven to move relative to the device main body 100 by telescoping of the telescopic cylinder; the driving mechanism 300 can also be a linear module, etc. In this way, the effective wearing length of the connecting band 200 can be adjusted by driving the second end of the connecting band 200 to move relative to the device main body 100 by the driving mechanism 300, so as to make the wearable device suitable for users with different body sizes and improve the user experience.

[0046] The pressure sensing device 400 comprises a pressure detection element 410 connected with at least one of the device body 100 and the connecting band 200. Optionally, the pressure detection element 410 can be connected with only the device body 100, or only the connecting band 200, or connected with the device body 100 and the connecting band 200. In any case, when the wearing part of the user extends into the space formed by the connecting band 200 and the device body 100, the wearing part of the user can apply pressure to the pressure detection element 410. The greater the pressure value, the tighter the wearing degree; the smaller the pressure value, the looser the wearing degree. Therefore, the size of the pressure value can represent whether the user wears comfortably. Optionally, the pressure detection element 410 can be a pressure sensor, or other components capable of detecting pressure values.

[0047] The wearable device controls the driving mechanism according to the pressure value detected by the pressure detection element 410 to adjust the space enclosed by the connecting band 200 and the device body 100. Optionally, the pressure detection element 410 is in communication connection with the driving mechanism 300. When the pressure value detected by the pressure detection element 410 is less than a preset pressure value, the driving mechanism 300 drives the second end of the connecting band 200 to move relative to the device body 100 in a first direction; when the pressure value detected by the pressure detection element 410 reaches the preset pressure value, the driving mechanism 300 stops working; when the pressure value detected by the pressure detection element 410 is greater than the preset pressure value, the driving mechanism 300 drives the second end of the connecting band 200 to move relative to the device body 100 in a second direction, wherein the first direction is opposite to the second direction. Optionally, the pressure detection element 410 can be in communication connection with the driving mechanism 300 through a controller, and the controller controls the driving mechanism 300 to work or stop working. The user can set the preset pressure value according to personal needs.

[0048] In the embodiments of the present application, the pressure detection element 410 is connected with at least one of the device main body 100 and the connecting band 200, so that the pressure detection element 410 can detect the pressure value applied to the device main body 100 or the connecting band 200 by the user. In the process of adjusting the connecting band 200, the size of the space enclosed by the connecting band 200 and the device main body 100 changes, and the pressure value applied to the device main body 100 or the connecting band 200 by the user also changes. The wearable device can control the driving mechanism 300 according to the pressure value detected by the pressure detection element 410, so as to adjust the space enclosed by the connecting band 200 and the device main body 100. When the pressure value detected by the pressure detection element 410 is appropriate, it indicates that the user reaches a relatively comfortable wearing state, at this time, the driving mechanism 300 can control the driving mechanism 300 to stop working, and the second end of the connecting band 200 no longer moves relative to the device main body 100, so as to keep the size of the space enclosed by the connecting band 200 and the device main body 100 constant. When the pressure value detected by the pressure detection element 410 is small, it indicates that the wearing degree is loose, and the space enclosed by the connecting band 200 and the device main body 100 is large, at this time, the driving mechanism 300 can control the driving mechanism 300 to drive the second end of the connecting band 200 to move relative to the device main body 100 along the first direction, so as to reduce the space enclosed by the connecting band 200 and the device main body 100. When the pressure value detected by the pressure detection element 410 is large, it indicates that the wearing degree is tight, and the space enclosed by the connecting band 200 and the device main body 100 is small, at this time, the driving mechanism 300 can control the driving mechanism 300 to drive the second end of the connecting band 200 to move relative to the device main body 100 along the second direction, so as to increase the space enclosed by the connecting band 200 and the device main body 100.

[0049] In this way, the wearable device can automatically control the driving mechanism 300 according to the pressure detection value of the pressure detection element 410, so as to lock the position of the second end of the connecting band 200, without manually locking the position of the second end of the connecting band 200 in the adjusting process, which is beneficial to simplify the adjusting process of the effective wearing length and is more convenient to use.

[0050] In an alternative embodiment, the pressure sensor can be directly arranged in at least one of the device body 100 and the connecting band 200, and the wearing part of the user directly applies pressure to the pressure detection element 410. In another embodiment, the pressure sensing device 400 further comprises an air bag 420 arranged in at least one of the device body 100 and the connecting band 200, and the pressure detection element 410 is arranged in the air bag 420. Specifically, the wearing part of the user directly applies pressure to the air bag 420, so that the air bag 420 deforms and causes the air pressure inside the air bag 420 to change, and the pressure detection element 410 directly detects the air pressure value in the air bag 420, that is, the wearing part of the user indirectly applies pressure to the pressure detection element 410, and the air pressure value in the air bag 420 represents whether the user wears comfortably. In this embodiment, since the volume of the pressure detection element 410 is small, the wearing part of the user is not uncomfortable due to the direct action of the pressure detection element 410 on the wearing part of the user, and the air bag 420 can deform and has a buffering effect, and the air bag 420 has a high degree of fit with the wearing part, which is beneficial to improve the wearing comfort.

[0051] Optionally, the preset pressure value can be in the range of 25-32kp.

[0052] In an alternative embodiment, the air bag 420 can only include an elastic deformation part 421, that is, the air bag 420 is a one-piece structure, and the wearing part of the user directly applies pressure to a part of the elastic deformation part 421, so that the part deforms, and at the same time, other parts of the elastic deformation part 421 also deform under the driving action of the internal air pressure to adapt to the internal air pressure of the air bag 420. Therefore, the elastic deformation part 421 of the air bag 420 can deform as a whole in all directions when it is pressed, the internal volume of the air bag 420 changes less, the pressure changes less when worn, the air bag 420 does not have obvious air pressure changes, and it is not conducive to the pressure detection element 410 to detect the pressure value.

[0053] In another embodiment, in combination with Figure 3 and Figure 4As shown, the air bag 420 includes an elastic deformation part 421, and oppositely arranged contact part 422 and connecting part 423, the contact part 422 is directly pressed by the wearing part of the user towards the space surrounded by the device main body 100 and the connecting band 200, the connecting part 423 is connected with the connecting band 200, that is, the air bag 420 is arranged on the connecting band 200, the first edge of the elastic deformation part 421 is connected with the contact part 422, and the second edge of the elastic deformation part 421 is connected with the connecting part 423, that is, the contact part 422, the connecting part 423 and the elastic deformation part 421 jointly form the internal space of the air bag 420. In the case that the pressure borne by the contact part 422 increases, the elastic deformation part 421 is compressed, the distance between the contact part 422 and the connecting part 423 decreases, the volume of the air bag 420 decreases, the internal air pressure of the air bag 420 increases, and the pressure value detected by the pressure detection element 410 increases; in the case that the pressure borne by the contact part 422 decreases, the elastic deformation part 421 restores the elastic deformation, that is, the elastic deformation part 421 is elongated, so that the distance between the contact part 422 and the connecting part 423 increases, the volume of the air bag 420 increases, the internal air pressure of the air bag 420 decreases, and the pressure value detected by the pressure detection element 410 decreases.

[0054] By using the elastic deformation part 421, the contact part 422 can be directly close to or away from the connecting part 423, that is, the movement direction of the contact part 422 when being pressed is guided, and the elasticity of the contact part 422 and the connecting part 423 is much lower than that of the elastic deformation part 421, so that the air bag 420 has a significant volume change, and further has a significant air pressure change, which is beneficial to the pressure value detection of the pressure detection element 410, and further improves the sensitivity of the pressure detection element 410.

[0055] In an optional embodiment, the number of the elastic deformation part 421 is at least two, and the at least two elastic deformation parts 421 include a first elastic deformation part and a second elastic deformation part, the first edge of the first elastic deformation part is connected with the first edge of the contact part 422, the second edge of the first elastic deformation part is connected with the first edge of the connecting part 423, the first edge of the second elastic deformation part is connected with the second edge of the contact part 422, and the second edge of the second elastic deformation part is connected with the second edge of the connecting part 423. In this way, the first edge of the contact part 422 is close to or away from the first edge of the connecting part 423 by the first elastic deformation part, and the second edge of the contact part 422 is close to or away from the second edge of the connecting part 423 by the second elastic deformation part, so that the whole contact part 422 can move along the extension direction of the elastic deformation part 421 when being pressed, so that the air bag 420 has a more significant volume change and air pressure change, which is beneficial to the pressure value detection of the pressure detection element 410.

[0056] Optionally, in combination with Figure 4 and Figure 5As shown, the air bag 420 is similar to a rectangular structure, the thickness of the air bag 420 is T, the length of the air bag 420 is L, the height of the air bag 420 is W, the volume of the air bag 420 is V0=L·W·T, when the contact portion 422 is pressed, the values of L and W remain unchanged, the value of T decreases, so the volume V0 of the air bag 420 decreases, and under the condition that the temperature and other conditions are the same, the volume decreases, so the air pressure value detected by the pressure detection element 410 increases.

[0057] In an optional embodiment, the contact portion 422 can be a flat plate type structure, or the contact portion 422 is an arc-shaped structure. Because the skin surface of some wearing parts of the human body such as the legs, arms and head is arc-shaped, compared with the former embodiment, the contact area of the contact portion 422 and the skin of the wearing part is increased, the contact portion 422 has a better fitting effect with the wearing part of the user, and it is beneficial to improve the wearing comfort of the user.

[0058] In an optional embodiment, the wearable device further comprises a mounting member 500, the mounting member 500 is slidably connected with the second end of the connecting band 200, and the driving mechanism 300 is arranged on the mounting member 500, that is, the mounting member 500 provides a mounting basis for the driving mechanism 300, and the driving mechanism 300 drives the second end of the connecting band 200 to slide relative to the mounting member 500. The mounting member 500 can be fixedly connected with the air bag 420 by welding, bonding or the like. Alternatively, the mounting member 500 can be arranged on the device main body 100.

[0059] In another embodiment, in combination with Figure 3 , Figure 8 and Figure 9 As shown, the outer surface of the air bag 420 is provided with a first mounting portion, the mounting member 500 is provided with a second mounting portion, one of the first mounting portion and the second mounting portion is a mounting groove 511, and the other is a mounting protrusion 424, and the mounting protrusion 424 can extend into the mounting groove 511. Alternatively, the connecting portion 423 of the air bag 420 is provided with a first mounting portion. By extending or separating the mounting protrusion 424 from the mounting groove 511, the connection or separation of the air bag 420 and the mounting member 500 can be achieved, so that the user can more conveniently install or disassemble the air bag 420 according to needs.

[0060] In an optional embodiment, the number of the mounting protrusions 424 and the mounting grooves 511 is at least two, each mounting protrusion 424 and each mounting groove 511 are respectively arranged at intervals, and each mounting protrusion 424 corresponds to each mounting groove 511 one by one. By using at least two mounting protrusions 424 and at least two mounting grooves 511, different positions of the air bag 420 can be connected with different positions of the mounting member 500 respectively, so as to ensure the stability of the air bag 420 in the mounted state.

[0061] In an optional embodiment, the installation protrusion 424 is connected with the installation groove 511. Figure 3 As shown in the figure, the installation protrusion 424 comprises a first protrusion part A and a second protrusion part B connected with each other, and the second protrusion part B protrudes from the surface of the first protrusion part A. Figure 9 As shown in the figure, the installation groove 511 is arranged on the installation member 500, and the installation groove 511 comprises a first limiting groove and a second limiting groove connected with each other, the first protrusion part A extends into the first limiting groove, the second protrusion part B extends into the second limiting groove, and the first protrusion part A and the second protrusion part B are respectively limited and matched with the installation member 500 in different directions. Specifically, the first limiting groove and the second limiting groove are respectively provided with openings for the first protrusion part A and the second protrusion part B to extend into, the first protrusion part A extends into the first limiting groove through the corresponding opening, and the second protrusion part B extends into the second limiting groove through the corresponding opening. By using the embodiment, the installation protrusion 424 and the installation groove 511 respectively have a bending structure, so as to limit the movement of the air bag 420 relative to the installation member 500 in different directions, which is beneficial to improve the installation stability of the air bag 420.

[0062] In the scheme of the present application, as shown in Figure 1 and Figure 2 The wearable device further comprises a touch screen 600, the touch screen 600 is arranged on the device main body 100, and the touch screen 600 is respectively connected with the driving mechanism 300 and the pressure detection element 410. Since the touch screen 600 has a large touch range and a large display range, the user can control the driving mechanism 300 by applying a corresponding touch instruction to any position of the touch screen 600, so as to realize the working or stopping of the driving mechanism 300. Compared with the mechanical switch mode of directly controlling the driving mechanism 300, this control mode is more convenient and easy to operate, and improves the convenience of the wearable device. At the same time, through the touch screen 600, the user can know the pressure value detected by the pressure detection element 410. Of course, in other embodiments, the wearable device can not be provided with the touch screen 600, and the user directly controls the mechanical switch of the driving mechanism 300.

[0063] In an optional embodiment, the number of the connection bands 200 can be one. In this way, the second end of the connection band 200 is connected with the device main body 100, and the connection space of the second end of the connection band 200 is limited by the device main body 100, which is not convenient for connection operation.

Moreover, the driving mechanism 300 is connected with at least one of the second end of the first connecting band 210 and the second end of the second connecting band 220, and the driving mechanism 300 drives at least one of the second end of the first connecting band 210 and the second end of the second connecting band 220 to move along the extension direction of the connecting band 200.

[0075] Based on the wearable device disclosed in the present application, the present embodiment further discloses a control method of a wearable device, which is applied to the wearable device in the above-mentioned embodiments, and the control method comprises the following steps:

[0076] S100, receiving a first input, the first input including a pressure value received by the wearable device or a touch instruction of the user to the wearable device. Optionally, the user applies pressure to the air bag 420 at the wearing part, and the air bag 420 generates pressure change under pressure, and the pressure value received by the wearable device is indirectly reflected by detecting the air pressure value inside the air bag 420 through the pressure detection element 410. Optionally, the device main body 100 is provided with a touch screen 600, and the touch instruction of the user to the wearable device is received through the touch screen 600.

[0077] S200, in the case that the touch instruction is a first instruction or the pressure value is less than a preset pressure value, the driving mechanism 300 drives the second end of the connecting band 200 to move relative to the device main body 100 in a first direction. Wherein, the user can set the preset pressure value according to needs.

[0078] S300, in the case that the touch instruction is a second instruction or the pressure value is equal to the preset pressure value, the driving mechanism 300 is controlled to drive the second end of the connecting band 200 to be stationary relative to the device main body 100.

[0079] S400, in the case that the touch instruction is the third instruction or the pressure value is greater than the preset pressure value, the driving mechanism 300 drives the second end of the connecting band 200 to move relative to the device body 100 along a second direction. The first direction is opposite to the second direction. Optionally, the pressure detection element 410 and the driving mechanism 300 are respectively in communication connection with the controller, and the controller controls the driving mechanism 300 according to the first input.

[0080] Optionally, the second instruction can be a single click, double click or the like instruction of the user to the touch screen 600; the first instruction can be a down swipe instruction of the user to the touch screen 600, and the third instruction can be an up swipe instruction of the user to the touch screen 600; the first instruction can also be a left swipe instruction of the user to the touch screen 600, and the third instruction can be a right swipe instruction of the user to the touch screen 600. Of course, the first instruction, the second instruction and the third instruction can also be other touch instructions, and the instruction types of the first instruction, the second instruction and the third instruction are different.

[0081] Optionally, in the case that the touch instruction is the first instruction, or in the case that the pressure value is less than the preset pressure value, the driving source 310 is controlled to rotate along a first rotation direction to drive the second end of the first connecting band 210 and the second end of the second connecting band 220 to approach each other, so as to adjust the effective wearing length of the connecting band 200. Meanwhile, the space formed by the connecting band 200 and the device body 100 is reduced, the pressure applied by the wearable part to the air bag 420 gradually increases, and the pressure value detected by the pressure detection element 410 also gradually increases. In the case that the pressure value reaches the preset pressure value, or in the case that the user applies the second instruction to the wearable device, the driving source 310 is controlled to drive the second end of the connecting band 200 to be stationary relative to the device body 100. In the case that the touch instruction is the third instruction, or in the case that the pressure value is greater than the preset pressure value, the driving source 310 is controlled to rotate along a second rotation direction to drive the second end of the first connecting band 210 and the second end of the second connecting band 220 to move away from each other, so as to increase the space formed by the connecting band 200 and the device body 100. At this time, the user can put on or take off the wearable device from the wearing part. The first rotation direction is opposite to the second rotation direction.

[0082] Further optionally, the wearable device can automatically control the driving mechanism 300 according to the received pressure value, can control the driving mechanism 300 according to the touch instruction, or can control the driving mechanism 300 according to the combination of the received pressure value and the touch instruction.

[0083] According to the control method, the first input is used to automatically control the driving mechanism 300 to adjust the effective wearing length of the connecting band 200, so as to adjust the tightness of the user during wearing. Moreover, the second end of the connecting band 200 driven by the driving mechanism 300 can be controlled to be static relative to the device main body 100 according to the pressure value, so as to lock the position of the second end of the connecting band 200, and the position of the second end of the connecting band 200 does not need to be manually locked separately during the adjustment process, which is beneficial to simplify the adjustment process of the effective wearing length and is more convenient to use.

[0084] In an optional embodiment, the control method further includes:

[0085] S500, in the case where the touch instruction is the fourth instruction, setting the current pressure value applied by the wearing part of the user to the wearable device as a preset pressure value. Optionally, the fourth instruction can be a triple-tap instruction of the user to the touch screen 600, and of course, the fourth instruction can also be other touch instructions, and the fourth instruction is different from the instruction types of the first instruction, the second instruction and the third instruction. Optionally, in the case where the touch instruction is the fourth instruction, the pressure value detected by the pressure detection element 410 is a pressure value that makes the user feel comfortable, so the pressure value detected by the pressure detection element 410 is set as the preset pressure value, and the driving mechanism 300 is further controlled according to the pressure value received by the wearable device or the subsequent touch instruction of the user to the wearable device.

[0086] In this way, the preset pressure value is directly set according to the fourth instruction, and the preset pressure value is determined every time the user wears the wearable device, so it is not necessary to frequently set the preset pressure value, which is beneficial to simplify the adjustment process. Moreover, when the user using the wearable device changes, the preset pressure value can be changed at any time, so as to adapt to the use requirements of different users.

[0087] The wearable device in the embodiment can be a smart watch, a smart bracelet, smart glasses, a smart helmet, smart shoes and the like, and the embodiment of the application is not limited in this regard.
