Detailed implementation manners

[0032] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. These embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0033] In view of the complex and cumbersome adjustment method for the length of the strap of a wearable device in the prior art, an embodiment of the present application proposes a solution for automatically retracting and extending the strap according to the force applied to the strap. After the strap is subjected to a certain pulling force, it will squeeze the strap rotating shaft around which the strap is wound. An induction device is provided on the strap rotating shaft to collect the pressure and transmit it to the control device. The control device drives the strap rotating shaft to rotate forward or backward according to the magnitude of the pressure, so as to automatically retract and extend the strap according to the magnitude of the pulling force.

[0034] Based on the above technical concept, an embodiment of the present application provides a wearable device, such as Figures 1 to 3 As shown, the wearable device 100 in this embodiment includes a device main body 200 and a strap 300. The strap includes a first strap end 310, a second strap end 320, and a main body portion. A first strap opening 210 is provided on one side of the device main body 200. A strap rotating shaft 220, a driving device, and a control device are provided inside the device main body 200. An induction device is provided on the strap rotating shaft 220. The first strap end 310 is inserted into the inside of the device main body 200 through the first strap opening 210 and connected to the strap rotating shaft 220, and the main body portion of the strap 300 can be wound around the strap rotating shaft 220;

[0035] The induction device detects the pressure exerted by the strap 300 on the strap rotating shaft 220 to obtain pressure data;

[0036] The control device acquires the pressure data and controls the driving device to drive the strap rotating shaft 220 to rotate in different directions according to the pressure data, so that the main body portion of the strap 300 is wound around the strap rotating shaft 220 or unwound from the strap rotating shaft 220, realizing the adjustment of the length of the strap 300.

[0037] In the wearable device of this embodiment, an induction device is provided on the strap rotating shaft. The induction device is used to collect the pressure and transmit it to the control device. The control device controls the working state of the driving device based on the magnitude of the pressure, and controls the strap rotating shaft to rotate forward or backward through the driving device, so as to wind the strap around the strap rotating shaft or unwind it from the strap rotating shaft, realizing a strap adjustment solution for automatically retracting and extending the strap according to the force applied to the strap. The strap adjustment method is simple and practical and suitable for mass production.

[0038] In some embodiments, the watch band rotating shaft 220 in this embodiment is rotatably disposed inside the device main body 200. Rolling bearings 221 are provided at both ends of the watch band rotating shaft 220, and through the rolling bearings 221, the watch band rotating shaft 220 is rotatably installed inside the device main body 200 at a position opposite to the first watch band opening 210.

[0039] Specifically, as Figure 1 shown, a rotating shaft mounting portion 222 is provided inside the device main body 200 near the first watch band opening 210. The rotating shaft mounting portion 222 is provided with a fixing groove 223 and a cover plate 224 for fixing the rolling bearing 221. The position near the first watch band opening 210 can be understood as the vacant position at the first watch band opening 210 inside the device main body 200.

[0040] The driving device of this embodiment includes a rotating shaft gear 231, a motor gear 232, and a rotating motor 233. The control device includes a control board assembly 250. The rotating motor 233 is welded to the control board assembly 250 and is connected to the controller on the control board assembly 250. The rotating shaft gear 231 is fixedly connected to one end of the watch band rotating shaft 220, the motor gear 232 is fixedly connected to the rotating motor 233, and the rotating shaft gear 231 is meshed with the motor gear 232.

[0041] As Figure 4 shown, the motor gear 232 is assembled on the rotating motor 233 in advance, and the rotating motor 233 is welded to the control board assembly 250. During assembly, first, the control board assembly 250 is fixed inside the device main body 200 by using four panel screws 251, and then the rotating shaft gear 231 is assembled on the watch band rotating shaft to form a watch band rotating shaft assembly as Figure 5 shown. Then, the rolling bearing 221 of the watch band rotating shaft assembly is installed in the fixing groove 223, and then the cover plate 224 is covered and fixed with four cover plate screws 227. During the installation process, the motor gear 232 and the rotating shaft gear 231 are kept in a meshed state.

[0042] The watch band rotating shaft assembly of this embodiment can be understood as the watch band rotating shaft 220 after installing the rolling bearing 221, the rotating shaft gear 231, and the pressure sensor 240. For the convenience of description, the watch band rotating shaft in this embodiment is provided with a detection position and a non-detection position. The non-detection position includes the middle position of the watch band rotating shaft 220 and the edge positions at a certain distance from both ends of the watch band rotating shaft 220. The middle position is, for example, the end for connecting the first end 310 of the watch band. The edge positions at both ends are, for example, used to install the rolling bearings 221. A detection position is set between the middle position and the edge positions of the watch band rotating shaft 220, and this detection position is used to install the pressure sensor 240.

[0043] The sensing device in this embodiment includes a plurality of pressure sensors 240. The plurality of pressure sensors 240 form at least one pressure sensor group having an annular structure. At least one pressure sensor group is disposed at the detection position of the watch band rotating shaft 220, such as Figure 8 As shown, each pressure sensor 240 in the pressure sensor group with an annular structure has a different pressure detection direction.

[0044] The pressure sensor group in this embodiment is, for example, Figure 8 The annular structure formed by arranging four pressure sensors 240 in a ring as shown. Those skilled in the art can flexibly set the number of pressure sensors 240 that make up the pressure sensor group to effectively detect the pressure in each direction.

[0045] In an alternative embodiment, the plurality of pressure sensors 240 of the sensing device form two pressure sensor groups. The two pressure sensor groups are respectively disposed at the detection positions at both ends of the watch band rotating shaft 220, that is, the first pressure sensor group is disposed at the detection position on one side of the central position of the watch band rotating shaft 220, and the second pressure sensor group is disposed at the detection position on the other side of the central position of the watch band rotating shaft 220. The first pressure sensor group and the second pressure sensor group are installed in a staggered manner, that is, they have a stagger angle. Each pressure sensor in the two pressure sensor groups corresponds to a different pressure detection direction.

[0046] Taking the example that the plurality of pressure sensors of the sensing device form four pressure sensor groups, combined with Figures 5 to 8 , a total of four pressure sensor groups are provided on the watch band rotating shaft 220. Among them, the first pressure sensor group Sensor1 and the second pressure sensor group Sensor2 are disposed at the detection positions on one side of the central position of the watch band rotating shaft 220, and the third pressure sensor group Sensor3 and the fourth pressure sensor group Sensor4 are disposed at the detection positions on the other side of the central position of the watch band rotating shaft 220. The first pressure sensor group Sensor1 and the second pressure sensor group Sensor2, for example, have a stagger angle of 45°, and the third pressure sensor group Sensor3 and the fourth pressure sensor group Sensor4, for example, also have a stagger angle of 45°.

[0047] It should be noted that if more pressure sensor groups are designed, the stagger angle can be smaller so that the pressure can be detected when the watch band rotating shaft 220 rotates to different positions. In practical applications, the pressure sensor groups at the detection positions on both sides of the central position of the watch band rotating shaft 220 may or may not have a stagger angle. For example, the first pressure sensor group Sensor1 and the third pressure sensor group Sensor3 may or may not have a stagger angle.

[0048] Such as Figure 7As shown, at the detection position of the watch band rotating shaft 220, there is an installation surface 225 for the pressure sensor 240. The number of installation surfaces 225 is the same as the number of pressure sensors 240 that make up the pressure sensor group. One pressure sensor 240 is fixedly installed on each installation surface 225. Of course, in actual applications, two or more pressure sensors 240 can also be fixedly installed on each installation surface, and those skilled in the art can set it flexibly.

[0049] In some alternative embodiments, to prevent the pressure sensor 240 from being worn by the watch band, the sensing device further includes an elastic ferrule 241 that is in close contact with the pressure sensor 240 in the pressure sensor group. The outer surface of the elastic ferrule 241 protrudes from the surface of the watch band rotating shaft 220. Among them, the elastic ferrule 241 can be made of silica gel material to effectively transmit the pressure of the watch band.

[0050] During the installation process, first fix the pressure sensor 240 on the installation surface 225, then put on the elastic ferrule 241, and then install the rolling bearing 221. As Figure 6 shown, the outer surfaces of the four elastic ferrules 241 are slightly higher than the outer surface of the watch band rotating shaft 220. The inner surface of the elastic ferrule 241 is in close contact with the pressure sensor 240, and the outer surface of the elastic ferrule 241 is in direct contact with the watch band 300. The pressure applied by the watch band 300 is transmitted to the pressure sensor 240 through the elastic ferrule 241.

[0051] In this embodiment, the first end 310 of the watch band includes a watch band winding portion 312 that fixedly winds around the watch band rotating shaft 220 at least once. Among them, the watch band winding portion 312 covers the elastic ferrule 241 and is in direct contact with the elastic ferrule 241, and has a set distance from the rolling bearing 221 to ensure that the watch band winding portion 312 does not affect the rotation of the rolling bearing 221.

[0052] As Figure 9 and Figure 10 shown, the watch band winding portion 312 is a part of the watch band. In this embodiment, the length of the watch band winding portion 312 can wind around the watch band rotating shaft 220 at least once, and the watch band winding portion 312 cannot be unwound from the watch band rotating shaft 220. The watch band winding portion 312 can achieve a fixed connection relationship with the watch band rotating shaft by means of an algorithm. For example, design a corresponding algorithm in the control device so that the maximum unwinding position of the watch band 300 is outside the watch band winding portion 312. Of course, the watch band winding portion 312 can also achieve a fixed connection relationship with the watch band rotating shaft by means of the installation method between the watch band and the watch band rotating shaft. For example, during the watch band installation process, use glue to fixedly bond the watch band winding portion 312 to the watch band rotating shaft 220 to ensure that in any case, the pressure sensor on the watch band rotating shaft 220 can detect the pressure generated by the watch band.

[0053] Combined with Figure 5 and Figure 10As shown, a hook 311 is provided at the end of the strap winding portion 312 (which can also be referred to as the end of the first end 310 of the strap). A strap fixing groove 226 that cooperates with the hook 311 is provided at a non-detection position (i.e., the central position described above) of the strap rotating shaft 220, and the hook 311 is snapped into the strap fixing groove 226. It should be noted that the width of the hook 311 should be less than the width of the strap 300. When the end of the strap winding portion 312 is fixed to the strap rotating shaft 220 through the hook 311, the hook 311 will not affect the pressure sensor 240 on the strap rotating shaft 220, and during the winding process of the strap 300, the pressure sensor 240 on the strap rotating shaft 220 can be covered.

[0054] Combined with Figure 2 and Figure 3 As shown, the installation process of the first end 310 of the strap, for example, includes: first inserting the first end 310 of the strap into the device main body 200 through the first strap opening 210, then inserting the hook 311 at the first end 310 of the strap into the strap fixing groove 226 at the middle position of the strap rotating shaft 220. Optionally, it can be strengthened by dispensing glue. Finally, the main body part of the strap 300 is completely wound around the strap rotating shaft 220 through the driving device. At this time, the second end 320 of the strap is located outside the device main body 200. Of course, after assembly, for example, when the wearable device 100 is powered on and turned on, the main body part of the strap 300 can also be received into the device main body 200 through the driving device.

[0055] Based on the above embodiments, the strap 300 in the present application has an initial state. In the initial state, the strap 300 exerts almost no pressure on the pressure sensor 240 on the strap rotating shaft 220, and the main body part of the strap 300 is completely received into the device main body 200. Referring to Figure 15 only the connecting rod 321 at the second end 320 of the strap is visible from the appearance.

[0056] It can be understood that in the initial state, the rotation motor 233 continuously applies a negative driving force to ensure that the main body part of the strap 300 is always placed inside the device main body 200 when not working. Here, the rotation motor 233 provides a negative driving force when rotating in the negative direction and a positive driving force when rotating in the positive direction. The negative driving force can be understood as a negative force that pulls the strap 300 to wind around the strap rotating shaft 220, and the positive driving force can be understood as a positive force that unwinds the strap 300 from the strap rotating shaft 220.

[0057] In some embodiments, as Figure 2 and Figure 11 shown, a second strap opening 260 is provided on the other side of the device main body 200, and the second end 320 of the strap is inserted into or pulled out of the device main body 200 through the second strap opening 260;

[0058] A U-shaped limiter 270 is provided inside the device body 200 at the second strap opening 260. When the U-shaped limiter 270 is in a first form, the U-shaped limiter 270 locks the second end 320 of the strap inserted into the device body 200. When the U-shaped limiter 270 is in a second form, the U-shaped limiter 270 releases the second end 320 of the strap inserted into the device body 200. Here, the second end 320 of the strap includes, for example, a connecting rod 321.

[0059] Here, the force required for the U-shaped limiter 270 to be in the first form or the second form can be provided by the strap 300. For example, when the strap 300 is pulled downward, the strap 300 can provide a downward pulling force for the U-shaped limiter 270, so that the U-shaped limiter 270 is in the first form; for another example, when the strap 300 is pulled upward, the strap 300 can provide an upward pulling force for the U-shaped limiter 270, so that the U-shaped limiter 270 is in the second form.

[0060] like Figure 1 As shown, the U-shaped stopper 270 includes an upper spring piece 271 and a lower spring piece 272 whose deformation states are consistent. The upper spring piece 271 and the lower spring piece 272 enclose a space for accommodating the second end 320 of the strap, that is, the second end 330 of the strap is inserted between the upper spring piece 271 and the lower spring piece 272 through the second strap opening 260, as shown in FIG. Figure 12 As shown, when the strap 300 is pulled upward, the second end 320 of the strap contacts the upper elastic sheet 271, driving the upper elastic sheet 271 and the lower elastic sheet 272 to deform upward to the second form, releasing the second end 320 of the strap, so that the second end 320 of the strap can be separated from the device body 200 through the second strap opening 260. Figure 13 As shown, when the strap 300 is pulled downward, the second end 320 of the strap contacts the lower elastic sheet 272, driving the upper elastic sheet 271 and the lower elastic sheet 272 to deform downward to the first form, locking the second end 320 of the strap to prevent the second end 330 of the strap from detaching from the device body 200.

[0061] like Figure 14 As shown, the upper spring piece 271 and the lower spring piece 272 are connected through the connecting end to form the U-shaped main body of the U-shaped limiter 270, that is, one opposite end of the upper spring piece 271 and the lower spring piece 272 extend and connect to each other to form a U-shaped structure.

[0062] The U-shaped limit member 270 also includes an upper mounting portion 273 for mounting an upper spring sheet 271 and a lower mounting portion 274 for mounting a lower spring sheet 272. The upper mounting portion 273 is located on both sides of the upper spring sheet 271, and the lower mounting portion 274 is located on both sides of the lower spring sheet 272. A limit member mounting portion 290 cooperating with the upper mounting portion 273 and the lower mounting portion 274 is provided inside the device body 200. The upper mounting portion 273 and the lower mounting portion 274 are clamped in the limit member mounting portion 290.

[0063] Optionally, the U-shaped limiting member 270 further includes a connecting portion 275. Both sides of the upper elastic piece 271 are connected to the upper mounting portion 273 through a connecting portion 275 respectively, and both sides of the lower elastic piece 272 are connected to the lower mounting portion 274 through a connecting portion 275 respectively. Refer to Figure 14 , the U-shaped limiting member 270 includes, for example, four strip-shaped connecting portions 275, and the deformation degree of the U-shaped main body portion is set through the strip-shaped connecting portions 275.

[0064] As Figure 11 shown, in some alternative embodiments, a limiting block 280 is further provided at a position in the device main body 200 opposite to the second watch band opening 260. The second watch band opening 260 is a stepped opening with a limiting shoulder 261. The limiting block 280, the limiting shoulder 261, the upper elastic piece 271 and the lower elastic piece 272 form a four-sided limiting environment for the accommodation space.

[0065] As Figure 13 shown, the connecting rod 321 is inserted between the upper elastic piece 271 and the lower elastic piece 272 from the second watch band opening 260. The connecting rod 321 contacts the lower elastic piece 272 under the action of a downward pulling force, driving the U-shaped limiting member 270 to be in the first state. At this time, the limiting block 280, the limiting shoulder 261, the upper elastic piece 271 and the lower elastic piece 272 form a four-sided limiting accommodation space, locking the connecting rod 321 in the four-sided limiting accommodation space. At this time, the second end 320 of the watch band is in a locked state, and the watch band 300 is fixedly connected to the device main body 200.

[0066] As Figure 12 shown, the connecting rod 321 contacts the upper elastic piece 271 under the action of an upward pulling force, driving the U-shaped limiting member 270 to be in the second state. A channel is formed between the upper elastic piece 271 and the limiting shoulder 261. The connecting rod 321 detaches from the device main body 200 through this channel from the second watch band opening 260. At this time, the second end 320 of the watch band is separated from the device main body 200.

[0067] Next, in combination with Figure 15 and Figure 16 describe the watch band adjustment process of the wearable device 100 in this embodiment.

[0068] As Figure 15As shown, in the initial state of the watch band 300, when it is necessary to pull out the watch band 300, hold the second end 320 of the watch band and pull the connecting rod 321 outwards. At this time, the main body part of the watch band wound around the watch band rotating shaft 220 will squeeze the pressure sensor 240 on the watch band rotating shaft 220. The pressure sensor 240 sends the detected pressure data to the controller, and the controller drives the rotation motor 233 to rotate forward, so that the main body part of the watch band is unwound from the watch band rotating shaft 220. After reaching a certain length, for example, the watch band can be put on the wrist, and then insert the connecting rod 321 into the device main body 200 from the second watch band opening 260, and pull the watch band 300 downwards to change the shape of the U-shaped limiting member 270 to lock the connecting rod 321, thereby completing the wearing process of the watch band.

[0069] As Figure 16 shown, when it is necessary to retract the watch band 300, pull the watch band 300 outwards. The pressure data detected by the pressure sensor 240 will increase, and the main body part of the watch band 300 will be further unwound from the watch band rotating shaft 220 until the wrist can be easily taken out. Then pull out the connecting rod 321 from the second watch band opening 260, thereby completing the storage process of the watch band.

[0070] In practical applications, the connecting rod 321 can also be pulled out from the second watch band opening 260 first. At this time, the watch band 300 is in a free state, and the pressure data detected by the pressure sensor tends to 0. The rotation motor 233 provides a negative driving force to pull the main body part of the watch band 300 to wind around the watch band rotating shaft 220 until it returns to the initial state of the watch band 300.

[0071] In the above adjustment process of the watch band 300, the working process of the control device is as follows:

[0072] Set the first pressure data range corresponding to the negative driving force, for example, [0, 0.5 Pa). When the pressure data obtained by the control device belongs to this range [0, 0.5 Pa), the control device controls the rotation motor 233 to provide a negative driving force. Under the action of the negative driving force, the watch band rotating shaft 220 rotates negatively, so that the main body part of the watch band 300 winds around the watch band rotating shaft 220 until the watch band returns to the initial state. The time for the watch band 300 to return to the initial state is related to the motor speed, and those skilled in the art can flexibly set it according to needs.

[0073] Set the second pressure data range corresponding to the first forward driving force, for example, [0.5, 5 Pa). When the pressure data acquired by the control device belongs to this range [0.5, 5 Pa), the control device controls the rotary motor 233 to provide a forward driving force. Under the action of the forward driving force, the watch band rotating shaft 220 rotates forward, causing the watch band 300 to unwind from the watch band rotating shaft 220. When the pressure generated by the first forward driving force approaches 5 Pa, the watch band reaches the maximum wearable length that can be freely adjusted. The maximum wearable length can be personalized according to the circumference of the user's wrist during the initialization process of the wearable device, or the factory default value of the wearable device can be adopted.

[0074] Set the third pressure data range corresponding to the second forward driving force maintaining, for example, [5, 8 Pa). When the pressure data acquired by the control device belongs to this range [5, 8 Pa), the rotary motor 233 stops rotating. At this time, the watch band rotating shaft 220 does not rotate, and the wearing length of the watch band 300 does not change either. That is, the watch band 300 neither continues to wind around the watch band rotating shaft 220 nor unwinds from the watch band rotating shaft 220, and the watch band 300 maintains the current wearing length.

[0075] Set the fourth pressure data range corresponding to the third forward driving force, for example, [8, X Pa). When the pressure data acquired by the control device belongs to this range 8, X Pa), the rotary motor 233 continues to provide a forward driving force. At this time, the watch band rotating shaft 220 continues to rotate forward, causing the watch band 300 to continue to unwind from the watch band rotating shaft 220 until the maximum unwinding length of the watch band 300 is reached. Here, X is the maximum detectable pressure data.

[0076] In this embodiment, the control device reads the pressure data of all the pressure sensors on the watch band rotating shaft 220 at a set frequency, calculates the average value of the pressure values of all the pressure sensors, and controls the working state of the rotary motor based on the average pressure data.

[0077] Belonging to the same technical concept as the wearable device in the foregoing embodiment, the embodiment of the present application also provides a method for adjusting the watch band of a wearable device. The wearable device in the following embodiments of the present application is the wearable device described in the foregoing embodiments, and will not be elaborated here.

[0078] Figure 17 Shows a schematic flowchart of a method for adjusting the watch band of a wearable device according to an embodiment of the present application. As Figure 17 shown, the method of this embodiment at least includes the following steps S1710 to step S1720:

[0079] Step S1710, detecting the pressure data generated by the watch band through the sensing device;

[0080] Step S1720: Control the main body of the watch band to wind around the watch band rotating shaft or unwind from the watch band rotating shaft according to the pressure data.

[0081] In some embodiments, the pressure data generated by the watch band is detected by an induction device, including: obtaining the pressure data detected by all pressure sensors in the induction device at a set frequency, calculating the average value of the pressure data of all pressure sensors, and obtaining the average pressure data.

[0082] In some embodiments, controlling the main body of the watch band to wind around the watch band rotating shaft or unwind from the watch band rotating shaft according to the pressure data includes:

[0083] Comparing the average pressure data with a pre-set first pressure data range and a second pressure data range, and the data ranges of the first pressure data range and the second pressure data range do not overlap;

[0084] If the average pressure data belongs to the first pressure data range, control the watch band to wind around the watch band rotating shaft until the watch band reaches the initial state; if the average pressure data belongs to the second pressure data range, control the watch band to unwind from the watch band rotating shaft until the watch band reaches the maximum wearing length that can be freely adjusted.

[0085] As mentioned above, the first pressure data range is, for example, [0, 0.5 Pa), and the second pressure data range is, for example, [0.5, 5 Pa). When the detected average pressure data tends to be 0, the watch band will wind around the watch band rotating shaft and return to the initial state. When the detected average pressure data is greater than 0.5 Pa, the watch band will unwind from the watch band rotating shaft, and the wearing length of the watch band will gradually increase. When the detected average pressure data tends to be 5 Pa, the wearing length of the watch band will gradually reach the maximum wearing length. When adjusting the wearing length of the watch band through the pressure data, to ensure a good experience for the user, the step length of the adjustment of the wearing length of the watch band can be set according to the second pressure data range, and when the pressure data changes, the wearing length of the watch band is adjusted smoothly according to the step length.

[0086] In some embodiments, when the average pressure data neither belongs to the first pressure data range nor belongs to the second pressure data range, the above Figure 17 method further includes:

[0087] When the average pressure data exceeds the second pressure data range and is within a preset third pressure data range, the control driving device stops driving the watch band rotating shaft from rotating, and maintains the current wearing length of the watch band; when the average pressure data exceeds the third pressure data range and is within a preset fourth pressure data range, the watch band is controlled to unwind from the watch band rotating shaft until it reaches the maximum unwindable length of the watch band; wherein, with reference to the end point of the second end of the watch band, the maximum unwindable length of the watch band is greater than the maximum wearing length of the watch band, and the data ranges of the first pressure data range, the second pressure data range, the third pressure data range and the fourth pressure data range do not overlap.

[0088] As described above, the third pressure data range is, for example, [5, 8 Pa), and the fourth pressure data range is, for example, [8, X Pa). When it is detected that the average pressure data is greater than 5 Pa and less than 8 Pa, the wearing length of the watch band does not change, avoiding accidental stretching of the watch band during wearing, which may cause the watch band to become loose and the wearable device to fall off the wrist. When it is detected that the average pressure data is greater than 8 Pa, it indicates that the user wants to store the watch band in the device body at this time. At this time, the watch band needs to be further unwound to ensure that the wrist can be easily taken out to facilitate the completion of the watch band storage.
