[0046] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0047] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0048] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0049] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] In a first aspect, an embodiment of the present application provides a wearable device, such as Figure 1 As shown, it includes a shell 1, a bracket 2 and a fixing belt 5. A driving device 3 is arranged in the shell 1. The bracket 2 is slidably arranged in the shell 1, and the driving device 3 is transmission-connected with the bracket 2 to drive the bracket 2 to slide in the shell 1. A pressure sensor 4 is arranged on the bracket 2. The first end of the fixing belt 5 is fixed on the shell 1, and the second end of the fixing belt 5 extends into the shell 1 and is fixed on the bracket 2. The bracket 2 can drive the second end of the fixing belt 5 to move in a direction close to or away from the first end of the fixing belt 5. When the second end of the fixing belt 5 drives the bracket 2 to move in a direction away from the first end of the fixing belt 5, the pressure detected by the pressure sensor 4 changes, and the power output by the driving device 3 changes.

[0052] The wearable device of the present application may be a smart watch, a smart bracelet, and AR / VR glasses, etc. The present application embodiment is described by taking the wearable device as a smart watch as an example.

[0053] The housing 1 provides a storage space for the main components of the wearable device and plays a role in protecting the main components of the wearable device. The shape, size, material, etc. of the housing 1 can be designed according to the needs of the actual product and are not specifically limited in this application. The driving device 3 arranged in the housing 1 is used to provide power for the sliding of the bracket 2 in the housing 1. For example, the driving device 3 can be a motor, and the driving device 3 outputs a linear reciprocating motion. The power output end of the driving device 3 is connected to the bracket 2. When the driving device 3 provides power, the driving device 3 drives the bracket 2 to slide linearly and reciprocatingly in the housing 1.

[0054] Alternatively, if Figure 6 and Figure 7 As shown, a track is provided in the housing 1 , and a bearing is provided on the bracket 2 . The bearing cooperates with the track so that the bracket 2 can be slidably provided in the housing 1 .

[0055] In a specific embodiment, the housing 1 is a dial of a smart watch. The dial of the smart watch is surrounded by a receiving cavity, and components such as a circuit board of the smart watch are arranged in the receiving cavity.

[0056] The fixing belt 5 can fix the shell 1 on the user. The fixing belt 5 is made of a flexible material and can be bent so that the fixing belt 5 forms a wearing space, which is convenient for the user to wear the wearable device. The material of the fixing belt 5 can be plastic or the like. The first end of the fixing belt 5 is fixedly set on the shell 1, and the second end of the fixing belt 5 is fixedly set on the bracket 2 in the shell 1. When the bracket 2 reciprocates in a straight line, the second end of the fixing belt 5 is driven to move synchronously, so that the second end of the fixing belt 5 moves in a direction close to or away from the first end of the fixing belt 5, so as to change the wearing space formed by the fixing belt 5, so that the wearing space can adapt to the wearing size of different users.

[0057] In a specific embodiment, Fig.14 As shown, the first end of the dial has a fixing column, and the first end of the fixing belt 5 is arranged around the fixing column and fixed to the fixing column. A through hole is provided on the second end of the dial, which is away from the first end of the dial, and the through hole is connected to the accommodating cavity formed by the dial. The second end of the fixing belt 5 enters the accommodating cavity of the dial through the through hole and is connected to the bracket 2 slidably arranged in the dial. Driven by the driving device 3, the bracket 2 drives the second end of the fixing belt 5 to move. Among them, when the bracket 2 drives the second end of the fixing belt 5 to move away from the first end of the fixing belt 5 under the drive of the driving device 3, the part of the fixing belt 5 located inside the dial will extend out of the dial, so that the wearing space formed by the fixing belt 5 and the dial is increased. At this time, the user can pass the hand through the increased wearing space to put the smart watch on the user's wrist; when the bracket 2 drives the second end of the fixing belt 5 to move toward the first end of the fixing belt 5 under the drive of the driving device 3, the part of the fixing belt 5 located outside the dial will enter the dial, so that the wearing space formed by the fixing belt 5 and the dial is reduced, until the fixing belt 5 is just put on the user's wrist.

[0058] A pressure sensor 4 is provided on the bracket 2 , so that the pressure sensor 4 is used to detect the pressure exerted on the bracket 2 by the fixing belt 5 .

[0059] In a specific embodiment, the bracket 2 is provided with an extrusion beam slidably connected to the bracket 2, and the pressure sensor 4 is provided between the extrusion beam and the bracket 2. The two ends of the fixing belt 5 are fixedly connected to the extrusion beam. When the second end of the fixing belt 5 pulls the extrusion beam, the extrusion beam slides on the bracket 2 and compresses the pressure sensor 4 between the extrusion beam and the bracket 2.

[0060] When the second end of the fixing belt 5 drives the bracket 2 to move in a direction away from the first end of the fixing belt 5, the pressure detected by the pressure sensor 4 changes, and the power output by the driving device 3 changes. In other words, the power output by the driving device 3 changes according to the pulling force of the user pulling the fixing belt 5, that is, when the user pulls the fixing belt 5 to make the second end of the fixing belt 5 move in a direction outside the housing 1, the second end of the fixing belt 5 will pull the bracket 2. At this time, the pressure of the fixing belt 5 on the bracket 2 will be detected by the pressure sensor 4, and the power output by the driving device 3 is controlled according to the size or change of the pressure detected by the pressure sensor 4. For example, when the pressure detected by the pressure sensor 4 is relatively small, the driving device 3 always outputs the power that causes the bracket 2 to drive the second end of the fixing belt 5 to move in a direction close to the first end of the fixing belt 5, ensuring that the smart watch can be reliably worn on the user's wrist; when the pressure detected by the pressure sensor 4 is relatively large, the driving device 3 outputs the power that causes the bracket 2 to drive the second end of the fixing belt 5 to move in a direction away from the first end of the fixing belt 5, ensuring that the wearing space is increased and convenient for users to wear.

[0061] In a specific embodiment, when the pressure detected by the pressure sensor 4 is less than 0.5Pa, the driving device 3 always outputs power to cause the bracket 2 to drive the second end of the fixing belt 5 to move in a direction close to the first end of the fixing belt 5; when the pressure detected by the pressure sensor 4 is between 0.5Pa-5Pa, the driving device 3 outputs power to cause the bracket 2 to drive the second end of the fixing belt 5 to move in a direction away from the first end of the fixing belt 5; when the pressure detected by the pressure sensor 4 is greater than 5Pa but less than 8Pa, the driving device 3 does not make any output, that is, it is in a static state, and the fixing belt 5 can be extended out of the dial under the action of the pulling force of the user; when the pressure detected by the pressure sensor 4 exceeds 8Pa, the driving device 3 outputs power to cause the bracket 2 to drive the second end of the fixing belt 5 to move in a direction away from the first end of the fixing belt 5, so that the fixing belt 5 becomes longer to reduce the pressure.

[0062] For example, when the smart watch is worn on the wrist, the pressure sensor 4 cannot detect the pressure, and the drive device 3 will drive the bracket 2 to drive the second end of the fixing belt 5 to move in the direction close to the first end of the fixing belt 5, so that the fixing belt 5 is tightened and the fixing belt 5 is reliably worn on the wrist. When the pressure detected by the pressure sensor 4 reaches the working pressure of 0.4Pa, the power output by the drive device 3 will keep the pressure detected by the pressure sensor 4 at 0.4Pa to ensure that the smart watch can be reliably worn. When the user pulls the fixing belt 5 so that the pressure detected by the pressure sensor 4 is 3Pa, the drive device 3 will drive the bracket 2 to drive the second end of the fixing belt 5 to move in the direction away from the first end of the fixing belt 5, so that the wearing space surrounded by the fixing belt 5 is increased, which is convenient for the user to take off the smart watch. When the user pulls the fixing belt 5 so that the pressure detected by the pressure sensor 4 is 6Pa, the drive device 3 does not make any output, which is convenient for the user to pull the fixing belt 5 out of the dial.

[0063] The present application sets the pressure sensor 4 on the bracket 2 and fixes the second end of the fixing belt 5 on the bracket 2, so that the pressure sensor 4 can detect the pressure of the fixing belt 5 on the bracket 2, and then controls the power output by the driving device 3 through the pressure detected by the pressure sensor 4 to make the second end of the fixing belt 5 move to change the wearing space formed by the fixing belt 5, thereby solving the problem of inconvenience for users to wear wearable devices.

[0064] Alternatively, if Fig.13 As shown, the bracket 2 includes a fixing beam 6, the pressure sensor 4 is arranged on the fixing beam 6, the second end of the fixing belt 5 is wound around and fixed on the fixing beam 6, and when the second end of the fixing belt 5 drives the bracket 2 to move in a direction away from the first end of the fixing belt 5, the fixing belt 5 wound on the fixing part squeezes the pressure sensor 4. The pressure sensor 4 can reliably detect the pressure of the fixing belt 5 on the bracket 2, which is convenient for the driving device 3 to make a timely and accurate response, which is conducive to the wearing of the wearable device.

[0065] In a specific embodiment, Figure 2 and Figure 5 As shown, the fixed beam 6 is fixed on the bracket 2, the fixed beam 6 is arranged close to the first side of the bracket 2, and the fixed beam 6 is parallel to the first side of the bracket 2. The pressure sensor 4 is arranged on the outer surface of the fixed beam 6. Fig.13 As shown, the second end of the fixing belt 5 is arranged around the outer surface of the fixing beam 6, so that the second end of the fixing belt 5 surrounds and forms a cavity that matches the shape and size of the fixing beam 6, and the fixing belt 5 contacts the pressure sensor 4. Then, the second end of the fixing belt 5 wrapped around the fixing beam 6 is fixed to the fixing beam 6. When the user pulls the fixing belt 5, the second end of the fixing belt 5 will squeeze the fixing beam 6 and can squeeze the pressure sensor 4 at the same time, so that the pressure sensor 4 can reliably detect the pressure.

[0066] Optionally, a groove 7 is formed on the fixing beam 6, and the pressure sensor 4 is arranged in the groove 7, and a flexible rubber sleeve 8 is also included, and the fixing beam 6 and the pressure sensor 4 are covered in the flexible rubber sleeve 8. This can make the fixation of the pressure sensor 4 more reliable, and at the same time can avoid the situation where the pressure sensor 4 is unevenly stressed, resulting in inaccurate pressure detected by the pressure sensor 4.

[0067] In a specific embodiment, Figure 3 , Figure 4 and Fig.16 As shown, a groove 7 is opened on the fixed beam 6, and the pressure sensor 4 is fixed at the bottom of the groove 7. The fixed beam 6 and the pressure sensor 4 are covered with a rubber sleeve. When the fixed beam 6 is pulled by the second end of the fixing belt 5, the position of the pressure sensor 4 will not change, and due to the action of the flexible rubber sleeve 8, the force applied by the fixing belt 5 to the flexible rubber sleeve 8 can be evenly transmitted to the pressure sensor 4, thereby avoiding the problem of uneven force on the pressure sensor 4.

[0068] Optionally, the portion of the flexible rubber sleeve 8 corresponding to the pressure sensor 4 is a contact portion, the inner surface of the contact portion is adapted to the pressure sensor 4, the outer surface of the contact portion is an arc-shaped outer surface, and the outer surface of the contact portion is in contact with the fixing belt 5 wound around the fixing portion. This can further avoid the problem of uneven force on the pressure sensor 4, making the detection result of the pressure sensor 4 more accurate.

[0069] In a specific embodiment, Fig.16As shown, the flexible rubber sleeve 8 has a portion in contact with the fixed beam 6 and a portion in contact with the pressure sensor 4, wherein the portion where the flexible rubber sleeve 8 and the pressure sensor 4 meet is the contact portion. The pressure sensor 4 has a stepped outer surface, and the contact portion has a stepped inner surface, and the stepped outer surface and the stepped inner surface match each other. When the contact portion is subjected to pressure from the fixing belt 5, the contact portion will transfer the pressure evenly to the pressure sensor 4. The outer surface of the contact portion, that is, the outer surface in contact with the fixing belt 5, is an arc outer surface, and the arc outer surface matches the inner surface of the curved fixing belt 5, thereby increasing the contact area between the two, and thereby enabling the fixing belt 5 to evenly transfer the pressure to the flexible rubber sleeve 8.

[0070] Alternatively, if Fig.15 and Fig.17 As shown, the fixing beam 6 is located on a side of the bracket 2 away from the first end of the fixing belt 5 , and the pressure sensor 4 is arranged on a side of the fixing beam 6 facing the first end of the fixing belt 5 .

[0071] Among them, Fig.17 As shown, the fixing beam 6 is located on the side of the bracket 2 away from the first end of the fixing belt 5. When the bracket 2 moves to the extreme position away from the first end of the fixing belt 5, the fixing belt 5 can be extended as far as possible from the dial, increasing the wearing space formed by the fixing belt 5, making it easier for users to wear the smart watch. Fig.15 As shown, the pressure sensor 4 is arranged on the side of the fixed beam 6 facing the first end of the fixed belt 5, that is, the second end of the fixed belt 5 approaches the fixed beam 6 from the side of the fixed beam 6 away from the bracket 2 and is wrapped around the fixed beam 6. At this time, the side of the fixed beam 6 facing the first end of the fixed belt 5 is exactly the side of the fixed beam 6 that is subjected to the greatest pressure. By arranging the pressure sensor 4 on the side of the fixed beam 6 facing the first end of the fixed belt 5, the pressure sensor 4 can be subjected to force more reliably.

[0072] Optionally, a rack 9 is provided on the bracket 2, and a gear 10 is provided on the driving device 3, the rack 9 is meshed with the gear 10, and when the driving device 3 drives the gear 10 to rotate, the bracket 2 slides in the housing 1. The bracket 2 can slide reliably in the housing 1.

[0073] In a specific embodiment, Figure 2 and Figure 5 As shown, the bracket 2 is a plate-like structure, and a rack 9 is arranged on the plate-like structure. Fig.11 and 12 As shown, the gear 10 on the driving device 3 is meshed with the rack 9 on the bracket 2 , so that the power of the driving device 3 can be reliably transmitted to the bracket 2 .

[0074] Alternatively, if Fig. 9 and Fig.10As shown, the housing 1 further includes a support plate 11, which has a notch. The support plate 11 is fixedly arranged in the housing 1, the driving device 3 is fixedly arranged on the support plate 11, and the gear 10 is located in the notch. In other words, the driving device 3 is fixedly arranged in the middle of the support plate 11, and the gear 10 of the driving device 3 is meshed with the rack 9 on the bracket 2 through the notch provided on the support plate 11, so that the driving device 3 can be fixed more reliably.

[0075] Optionally, the support plate 11 is a circuit board, the driving device 3 is electrically connected to the support plate 11, and the pressure sensor 4 is electrically connected to the support plate 11. The wearable device of the present application can be highly integrated and the volume of the wearable device can be effectively reduced.

[0076] In a specific embodiment, a control system is provided on the support plate 11 , and the pressure measured by the pressure sensor 4 is transmitted to the control system. The control system controls the driving system provided on the support plate 11 according to the pressure detected by the pressure sensor 4 .

[0077] Optionally, a limiting protrusion 12 is provided at the end of the rack 9, and the height of the limiting protrusion 12 is greater than the height of the rack 9. The stroke of the bracket 2 can be reliably limited to prevent the bracket 2 from deviating from the predetermined stroke.

[0078] For example, Fig.12 and Fig.17 As shown, when the bracket 2 moves away from the first end of the fixing belt 5, the limiting protrusion 12 interferes with the gear 10, which can prevent the bracket 2 from continuing to drive the second end of the fixing belt 5 to move away from the first end of the fixing belt 5. Figure 8 , Fig.11 and Fig.15 As shown, when the bracket 2 moves toward the direction close to the first end of the fixing belt 5, the limiting protrusion 12 interferes with the shell 1, which can prevent the bracket 2 from continuing to drive the second end of the fixing belt 5 to move toward the first end of the fixing belt 5.

[0079] In a second aspect, the present application provides a method for adjusting the length of a fixing strap, which is applied to the above wearable device, comprising:

[0080] Acquire the real-time pressure detected by the pressure sensor 4;

[0081] In response to the real-time pressure, the driving device 3 is controlled to change the output power;

[0082] The real-time pressure obtained is the first pressure, and the driving device 3 is controlled to output the first power;

[0083] The real-time pressure obtained is the second pressure, and the driving device 3 is controlled to output a second power, the direction of the second power being opposite to the direction of the first power;

[0084] The acquired real-time pressure is the third pressure, and the driving device 3 is controlled to stop outputting power.

[0085] The embodiment of the present application enables the power output by the driving device 3 to change in accordance with the pressure of the fixing belt 5 on the bracket 2, so that the user can conveniently wear the wearable device, thereby realizing the intelligence of the wearable device.

[0086] Optionally, the range of the first pressure is less than 0.5 Pa, the acquired real-time pressure is the first pressure, and the driving device 3 is controlled to drive the bracket 2 to move toward the direction close to the first end of the fixing belt 5 .

[0087] That is to say, when the user pulls the fixing strap 5 so that the pressure applied by the fixing strap 5 to the pressure sensor 4 is less than 0.5Pa, the driving device 3 always outputs a positive force so that the bracket 2 drives the second end of the fixing strap 5 to move in a direction close to the first end of the fixing strap 5, so that the fixing strap 5 shrinks into the shell 1 under the action of the driving device 3, so that the wearable device can be reliably worn on the user's hand.

[0088] Optionally, the range of the second pressure is greater than or equal to 0.5 Pa and less than or equal to 5 Pa, the acquired real-time pressure is the second pressure, and the control driving device 3 drives the bracket 2 to move in a direction away from the first end of the fixing belt 5.

[0089] That is to say, when the user pulls the fixing strap 5 so that the pressure exerted by the fixing strap 5 on the pressure sensor 4 is between 0.5Pa-5Pa, the driving device 3 outputs a negative force to cause the bracket 2 to drive the second end of the fixing strap 5 to move in a direction away from the first end of the fixing strap 5, so that the fixing strap 5 extends out of the shell 1 under the action of the driving device 3, so that the wearable device can be taken off from the user's wrist.

[0090] Optionally, the third pressure ranges from greater than 5Pa to less than 8Pa.

[0091] That is to say, when the user pulls the fixing belt 5 so that the pressure exerted by the fixing belt 5 on the pressure sensor 4 is greater than 5Pa and less than 8Pa, the driving device 3 does not make any output, that is, it is in a static state, and the fixing belt 5 can be extended out of the shell 1 under the pulling force of the user.

[0092] In a specific embodiment, when the pressure detected by the pressure sensor 4 is less than 0.5Pa, the driving device 3 always outputs a positive force so that the bracket 2 drives the second end of the fixing belt 5 to move toward the direction close to the first end of the fixing belt 5; when the pressure detected by the pressure sensor 4 is between 0.5Pa-5Pa, the driving device 3 outputs a negative force so that the bracket 2 drives the second end of the fixing belt 5 to move away from the first end of the fixing belt 5; when the pressure detected by the pressure sensor 4 is greater than 5Pa but less than 8Pa, the driving device 3 does not make any output, that is, it is in a stationary state, and can make the fixing belt 5 extend out of the dial under the action of the pulling force of the user.

[0093] In a third aspect, the present application provides a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the above method for adjusting the length of a fixed belt are implemented.

[0094] The readable storage medium includes a computer-readable storage medium, such as a computer read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc.
