Description

Technical Field

[0001] This application belongs to the field of electronic device technology, specifically relating to a watch strap and a wearable device. Background Technology

[0002] In related technologies, the watch straps of wearable devices are basically perforated straps with buckles. Different wrist sizes are adapted by matching different perforations. However, this perforation scheme makes the fit intermittent and discontinuous. Some people's wrist sizes cannot be completely matched. If one hole is too loose, it will be too tight. When wearing the watch, it will be too loose or too tight, and it will be impossible to adjust it to a satisfactory tightness. Summary of the Invention

[0003] This application aims to provide a watch strap and a wearable device that at least solves the problem that the watch strap size adjustment is discontinuous, resulting in the strap being too loose or too tight when worn.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a watch strap, comprising: an adjustment box; a strap body, wherein a first end and a second end of the strap body extend into the adjustment box from opposite ends of the adjustment box and together with the adjustment box to form a sealed cavity; at least one of the first end and the second end is provided with an air pressure balancing part, and at least one of the first end and the second end is slidable relative to the adjustment box to adjust the length of the watch strap; when at least one of the first end and the second end slides relative to the adjustment box, the air pressure balancing part moves within the sealed cavity to adjust the air pressure within the sealed cavity.

[0006] Secondly, embodiments of this application provide a wearable device, including: a watch strap as described in any of the first aspects.

[0007] In the embodiments of this application, the watch strap includes an adjustment box and a strap body. The strap body includes a first end and a second end, which extend into the adjustment box from opposite ends and together with the adjustment box to form a sealed cavity. At least one of the first and second ends is provided with an air pressure balancing part. When at least one of the first and second ends slides relative to the adjustment box, the volume of the sealed cavity changes, causing a change in the air pressure within the sealed cavity. The air pressure balancing part moves within the sealed cavity, adjusting the air pressure within the sealed cavity to maintain balance with the air pressure in the space where the watch strap is located. The watch strap proposed in this application, through the adjustment of the air pressure in the sealed cavity, can achieve continuous expansion and contraction in size. Different users can adjust it to their desired tightness according to their size and comfort, without the problem of being too loose or too tight, improving wearing comfort and ensuring the reliability of detection by wearable devices with detection functions.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0019] The following is combined Figures 1-3 This application describes a watch strap and a wearable device according to embodiments thereof.

[0020] like Figure 1 As shown, a watch strap according to some embodiments of this application includes: an adjustment box 1; a strap body 2, wherein a first end 200 and a second end 220 of the strap body 2 extend into the adjustment box 1 from opposite ends of the adjustment box 1 and together with the adjustment box 1 to form a sealed cavity 3; at least one of the first end 200 and the second end 220 is provided with an air pressure balancing part 4, and at least one of the first end 200 and the second end 220 is slidable relative to the adjustment box 1 to adjust the length of the watch strap. When at least one of the first end 200 and the second end 220 slides relative to the adjustment box 1, the air pressure balancing part 4 moves within the sealed cavity 3 to adjust the air pressure within the sealed cavity 3.

[0021] In the embodiments of this application, the watch strap includes an adjustment box 1 and a strap body 2. The strap body 2 includes a first end 200 and a second end 220. The first end 200 and the second end 220 extend into the adjustment box 1 from opposite ends and together with the adjustment box 1 to form a sealed cavity 3. At least one of the first end 200 and the second end 220 is provided with an air pressure balancing part 4. When at least one of the first end 200 and the second end 220 slides relative to the adjustment box 1, the volume of the sealed cavity 3 changes, causing a change in the air pressure within the sealed cavity 3. The air pressure balancing part 4 moves within the sealed cavity 3, thereby adjusting the air pressure within the sealed cavity 3 and maintaining a balance between the air pressure within the sealed cavity 3 and the air pressure in the space where the watch strap is located. The watch strap proposed in this application, through the adjustment of the air pressure in the sealed cavity 3, can achieve continuous expansion and contraction in size. Different users can adjust it to their desired tightness according to their own size and comfort, without the problem of being too loose or too tight, improving wearing comfort and ensuring the reliability of the detection function of wearable devices.

[0022] It is understandable that when the watch strap slides relative to the adjustment box 1, it can slide to any size. At any position, the air pressure balance part 4 maintains the air pressure balance between the sealed cavity 3 and the external space of the watch strap. When the sealed cavity 3 and the external air pressure are balanced, the strap body 2 is locked.

[0023] It should be noted that the adjustment of the watch strap length includes shortening and lengthening. When at least one of the first end 200 and the second end 220 slides outward from the adjustment box 1, the length of the watch strap increases; when at least one of the first end 200 and the second end 220 slides inward from the adjustment box 1, the length of the watch strap decreases.

[0024] Optionally, the adjustment box 1 includes a box body with openings at opposite ends. At least one of the first end 200 and the second end 220 extends into the box body from opposite ends.

[0025] In practical applications, the watch strap may have only one strap body 2; or it may have two strap bodies 2. For example, the strap body 2 includes a first strap body 20 and a second strap body 22. The first strap body 20 includes a first end 200, and the second strap body 22 includes a second end 220.

[0026] like Figure 1 and Figure 2As shown, according to some embodiments of this application, the air pressure balance part 4 includes: a gas channel 40, disposed at least one of the first end 200 and the second end 220, the gas channel 40 extending within the belt body 2, and at least one end of the gas channel 40 penetrating the side wall of the belt body 2, and at least one end of the gas channel 40 penetrating the end face of the end of the belt body 2 located within the adjustment box 1; a sealing member 41, disposed in the gas channel 40, for opening or closing the gas channel 40; when at least one of the first end 200 and the second end 220 slides relative to the adjustment box 1, the sealing member 41 opens the gas channel 40, and the gas channel 40 connects the sealing cavity 3 and the space where the watch strap is located.

[0027] In this embodiment, the pressure balancing unit 4 includes a gas channel 40 and a seal 41. The gas channel 40 is disposed on at least one of the first end 200 and the second end 220, extending within the strap body 2. At least one end of the gas channel 40 penetrates the end face of the strap body 2 extending into the adjustment box 1, allowing the gas channel 40 to communicate with the sealing cavity 3. At least one end of the gas channel 40 also penetrates the side wall of the strap body 2, allowing the gas channel 40 to communicate with the space outside the strap. The seal 41 is disposed on the gas channel 40 and is used to open or close the gas channel 40. When at least one of the first end 200 and the second end 220 slides relative to the adjustment box 1, the seal 41 opens the gas channel 40, connecting the sealing cavity 3 and the external space where the strap is located. This allows air to circulate between the sealing cavity 3 and the external space, thereby regulating the pressure within the sealing cavity 3 and balancing the pressure between the sealing cavity 3 and the external space of the strap. This allows the strap body 2 to move smoothly, enabling adjustment of the strap length to any desired dimension.

[0028] It should be noted that when the sealing element 41 closes the gas passage 40, the sealing cavity 3 is in a sealed state. This means that when the gas pressure inside the sealing cavity 3 is balanced with the external air pressure, the sealing element 41 closes the gas passage 40, and the sealing cavity 3 is in a sealed state to ensure the locking between the belt body 2 and the regulating box 1.

[0029] In specific applications, the movement of the seal 41 can be achieved by the pressure difference between the air pressure inside the sealing cavity 3 and the air pressure outside the watch strap, or the movement of the seal 41 can be achieved by the drive unit.

[0030] like Figure 2 and Figure 3As shown, according to some embodiments of this application, the number of gas channels 40 is at least two, and the sealing member 41 includes a first sealing member 410 and a second sealing member 412. The first sealing member 410 and the second sealing member 412 are respectively disposed in at least two gas channels 40. When at least one of the first end 200 and the second end 220 slides into the regulating box 1, the volume of the sealing cavity 3 decreases, and the first sealing member 410 moves away from the sealing cavity 3 to open the corresponding gas channel 40. When at least one of the first end 200 and the second end 220 slides outward from the regulating box 1, the volume of the sealing cavity 3 increases, and the second sealing member 412 moves into the sealing cavity 3 to open the corresponding gas channel 40.

[0031] In this embodiment, the number of gas channels 40 is at least two, and the sealing element 41 includes a first sealing element 410 and a second sealing element 412. The first sealing element 410 and the second sealing element 412 are respectively disposed in at least two gas channels 40 to control the opening and closing of the corresponding gas channels 40 respectively. When at least one of the first end 200 and the second end 220 slides outward from the adjustment box 1, the length of the watch strap increases, the volume of the sealing cavity 3 increases, the air pressure inside the sealing cavity 3 decreases, and the second seal 412 moves into the sealing cavity 3, thereby opening the gas channel 40 corresponding to the second seal 412. This balances the external air pressure with the air pressure inside the sealing cavity 3, ensuring smooth sliding of the strap 2 while locking the strap 2 at any position. When at least one of the first end 200 and the second end 220 slides inward from the adjustment box 1, the length of the watch strap decreases, the volume of the sealing cavity 3 decreases, and the air pressure inside the sealing cavity 3 increases. This drives the first seal 410 to move away from the sealing cavity 3 to open the gas channel 40 corresponding to the first seal 410. This balances the external air pressure with the air pressure inside the sealing cavity 3, ensuring smooth sliding of the strap 2 while locking the strap 2 at any position.

[0032] Specifically, the pressure difference between the air pressure in the external space and the air pressure inside the sealed cavity 3 drives the second seal 412 and the first seal 410 to move.

[0033] It is understood that the second seal 412 is disposed in at least one gas channel 40, and the first seal 410 is disposed in at least one of the other gas channels 40, such that the second seal 412 and the first seal 410 respectively control the opening and closing of the corresponding gas channels 40, so that at least one gas channel 40 is opened when the watch strap is extended, and at least one is opened when the watch strap is shortened.

[0034] In specific applications, there are two belt bodies 2 (e.g., the first belt body 20 and the second belt body 22). Each belt body 2 is provided with at least one gas channel 40. One belt body 2 is provided with a second seal 412, and the other belt body 2 is provided with a first seal 410.

[0035] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, any gas channel 40 includes a first channel 400 and a second channel 402 that are connected. The first channel 400 passes through the end face of one end of the belt body 2 located inside the adjustment box 1 and extends in a direction away from the sealing cavity 3. The second channel 402 passes through the side wall of the belt body 2. The second sealing member 412 is disposed at the end of the corresponding first channel 400 near the sealing cavity 3, and the first sealing member 410 is disposed at the end of the corresponding first channel 400 near the second channel 402.

[0036] In this embodiment, the gas channel 40 includes a first channel 400 and a second channel 402 that are connected to each other. The first channel 400 passes through the end face of one end of the strap 2 located inside the adjustment box 1, thereby communicating with the sealing cavity 3. The second channel 402 passes through the side wall of the strap 2, thereby communicating with the external space of the strap. The second seal 412 is disposed at one end of the corresponding first channel 400 near the sealing cavity 3. When at least one of the first end 200 and the second end 220 slides outward from the sealing cavity 3, the strap length increases and the volume of the sealing cavity 3 increases. Under the action of the air pressure difference, the second seal 412 moves into the sealing cavity 3 to open the gas channel 40. The first seal 410 is disposed at one end of the corresponding first channel 400 near the second channel 402. When at least one of the first end 200 and the second end 220 slides into the sealing cavity 3, the strap length decreases and the volume of the sealing cavity 3 decreases. Under the action of the air pressure difference, the first seal 410 moves away from the sealing cavity 3 to open the gas channel 40. While realizing the air pressure regulation in the sealing cavity 3, it can also prevent the first seal 410 from being exposed, ensuring the locking effect of the strap 2 in the sealed state of the sealing cavity 3 and improving the aesthetics of the strap.

[0037] like Figure 3 As shown, according to some embodiments of this application, the two ends of the second channel 402 penetrate the two opposite sidewalls of the belt body 2, the second channel 402 is provided with a connecting port 404, the first channel 400 is connected to the connecting port 404, and the first sealing member 410 is provided at the connecting port 404.

[0038] In this embodiment, the two ends of the second channel 402 penetrate the two opposite sidewalls of the strap 2, giving the second channel 402 two outlets, thereby increasing the speed of air pressure balance between the sealing cavity 3 and the external space of the strap. A connecting port 404 is provided on the second channel 402, through which the first channel 400 communicates with the second channel 402. A first sealing member 410 is disposed at the connecting port 404. Thus, when at least one of the first end 200 and the second end 220 slides into the adjusting box 1, the first sealing member 410 moves into the second channel 402, connecting the first channel 400 and the second channel 402, thereby opening the airflow channel and achieving communication between the sealing cavity 3 and the external space of the strap. Furthermore, this arrangement facilitates the processing of the airflow channel, reduces processing difficulty, and thus reduces processing costs.

[0039] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, the air pressure balance part 4 further includes: an elastic member 42, which connects the seal 41 and the strap 2, and is used to drive the seal 41 to close the gas passage 40 to lock the length of the strap.

[0040] In this embodiment, the air pressure balance part 4 also includes an elastic element 42, which is connected to the sealing element 41 and the strap body 2. The elastic element 42 can drive the sealing element 41 to close the gas passage 40, thereby closing the sealing cavity 3, locking the length of the strap, and ensuring the stability of the strap after length adjustment.

[0041] In a specific application, when at least one of the first end 200 and the second end 220 slides into or out of the adjustment box 1, the pressure difference between the inside and outside of the air overcomes the elastic force of the elastic element 42, driving the sealing element 41 to open the gas channel 40, thereby achieving communication between the gas channel 40 and the space where the watch strap is located. When the air pressure in the sealing cavity 3 is balanced with the external air pressure, the elastic element 42 resets, driving the sealing element 41 to seal the gas channel 40, thereby locking the length of the watch strap.

[0042] Optionally, the elastic element 42 includes: a first elastic element 420, which is connected to the first seal 410 and the strap body 2, for driving the first seal 410 to close the gas passage 40 to lock the length of the watch strap; and a second elastic element 422, which is connected to the second seal 412 and the strap body 2, for driving the second seal 412 to close the gas passage 40 to lock the length of the watch strap.

[0043] Specifically, the first elastic element 420 is located on the side of the first seal 410 closer to the sealing cavity 3. The second elastic element 422 is located on the side of the second seal 412 away from the sealing cavity 3.

[0044] Optionally, when the second seal 412 closes the gas passage 40, the second elastic member 422 is in a state of tensile deformation, and when the first seal 410 closes the gas passage 40, the first elastic member 420 is in a state of tensile deformation.

[0045] According to some embodiments of this application, the portion of the belt 2 located inside the adjustment box 1 is provided with a sealing part 5, and the belt 2 is sealed to the inner wall surface of the adjustment box 1 through the sealing part 5.

[0046] In this embodiment, a sealing part 5 is provided on the portion of the strap 2 located inside the adjustment box 1, so that the strap 2 is sealed to the inner wall of the adjustment box 1 through the sealing part 5, thereby forming a sealed cavity 3 with the adjustment box 1 to realize the adjustment of the strap to any size.

[0047] It is understood that the sealing part 5 is provided on the belt body 2, and the belt body 2 is sealed with the adjustment box 1 through the sealing part 5. It can also move relative to the adjustment box 1 through the sealing part 5. That is, when at least one of the first end 200 and the second end 220 moves relative to the adjustment box 1, the sealing part 5 also moves relative to the adjustment box 1 along with at least one of the first end 200 and the second end 220.

[0048] Optionally, the sealing part 5 and the belt body 2 are an integral structure.

[0049] According to some embodiments of this application, there is a gap between the belt body 2 and the inner wall surface of the adjustment box 1, the belt body 2 slides relative to the adjustment box 1 through the sealing part 5, and the air pressure balance part 4 communicates with the gap.

[0050] In this embodiment, there is a gap between the belt body 2 and the inner wall of the adjusting box 1, so that the belt body 2 moves relative to the adjusting box 1 only through the sealing part 5, reducing the contact area with the inner wall of the adjusting box 1, thereby reducing the frictional resistance when the belt body 2 moves relative to the adjusting box 1 and improving the smoothness of the belt body 2 sliding. The air pressure balance part 4 is connected to the gap to realize the adjustment of the air pressure in the sealing cavity 3.

[0051] According to some embodiments of this application, the sealing portion 5 protrudes from the belt body 2 along the periphery of the belt body 2.

[0052] In this embodiment, the sealing part 5 protrudes from the belt body 2 along the periphery of the belt body 2 to achieve a seal with the inner wall of the adjustment box 1 around the periphery of the belt body 2, thereby ensuring the airtight performance of the sealing cavity 3.

[0053] According to some embodiments of this application, the sealing portion 5 on the first end 200 is disposed near the end of the first end 200, the sealing portion 5 on the second end 220 is disposed near the end of the second end 220, or the sealing portion 5 on the first end 200 is flush with the end of the first end 200, and the sealing portion 5 on the second end 220 is flush with the end of the second end 220.

[0054] In this embodiment, the sealing portion 5 on the first end 200 is disposed near the end of the first end 200, and the sealing portion 5 on the second end 220 is disposed near the end of the second end 220, or the sealing portion 5 on the first end 200 is flush with the end of the first end 200, and the sealing portion 5 on the second end 220 is flush with the end of the second end 220, so as to increase the adjustable range of the sealing cavity 3.

[0055] According to some embodiments of this application, the sealing part 5 includes a flexible member 6, which is interference-fitted with the inner wall surface of the adjusting box 1.

[0056] In this embodiment, the sealing part 5 includes a flexible member 6, which ensures the sealing performance of the sealing cavity 3. At the same time, the belt 2 can slide against the inner wall of the adjustment box 1 through the flexible member 6. The flexible member 6 is interference-fitted with the inner wall of the adjustment box 1, which can also ensure the sealing performance of the belt 2 when it moves relative to the adjustment box 1.

[0057] According to some embodiments of this application, the belt body 2 includes a first belt body 20 and a second belt body 22, the first belt body 20 includes a first end 200, and the second belt body 22 includes a second end 220.

[0058] In this embodiment, the strap 2 includes a first strap 20 and a second strap 22, which improves the flexibility of strap length adjustment.

[0059] In practical applications, when it is necessary to reduce the overall length of the watch strap, the first strap body 20 and the second strap body 22 apply external forces inward respectively, and the first end 200 and the second end 220 slide inward simultaneously. The air pressure inside the sealed cavity 3 increases, and the air pressure balancing part 4 adjusts the air pressure inside the sealed cavity 3. After the external force is removed, the internal and external air pressures reach equilibrium, and the watch strap length is locked. When it is necessary to increase the overall length of the watch strap, external forces are applied outward to the first strap body 20 and the second strap body 22 respectively, causing the first end 200 and the second end 220 to slide outward simultaneously. The air pressure inside the sealed cavity 3 decreases, and the air pressure balancing part 4 adjusts the air pressure inside the sealed cavity 3. After the external force is removed, the internal and external air pressures reach equilibrium, and the watch strap length is locked.

[0060] According to one embodiment of this application, a wearable device is proposed, comprising: a watch strap as proposed in any of the above embodiments.

[0061] In practical applications, this application proposes a solution for adjusting the size of the watch strap by means of air pressure balance. This fit size is continuous, and different users can adjust it to their own satisfactory tightness according to their size and comfort, without the problem of being too loose or too tight.

[0062] like Figures 1 to 3As shown, the mechanism comprises a belt body A (e.g., first belt body 20), a belt body B (e.g., second belt body 22), an adjustment box 1, a sealing ball A (e.g., first seal 410), a sealing ball B (e.g., second seal 412), a tension spring A (e.g., first elastic element 420), and a tension spring B (e.g., second elastic element 422), for a total of 7 parts.

[0063] The strap body A, sealing ball A, and tension spring A form a component D. The strap body B, sealing ball B, and tension spring B form a component E. Both components are part of the watch strap, are sealed and assembled with the adjustment box 1, and can slide freely for adjustment.

[0064] Working principle:

[0065] Components D and E are assembled inside adjustment box 1, with their inner walls completely sealed, forming a completely enclosed cavity. When the overall length of the watch band needs to be reduced, components D and E slide inward with external force, increasing the air pressure inside the enclosed cavity (e.g., sealed cavity 3). The sealing ball A is pushed open, releasing the air pressure inside the cavity. After the external force is removed, the internal and external air pressures reach equilibrium, and the watch band length is locked. When the overall length of the watch band needs to be increased, components D and E slide outward with external force, decreasing the air pressure inside the enclosed cavity. The external air pressure becomes greater than the internal air pressure, pushing the sealing ball B open, allowing outside air to enter the enclosed cavity. After the external force is removed, the internal and external air pressures reach equilibrium, and the watch band length is locked.

[0066] This application provides an innovative design method that controls the position of the watch strap by balancing internal and external air pressure, thereby achieving the function of continuously adjusting the size of the watch strap. It perfectly realizes the continuity of wrist strap fit size, can be adapted to users with all different wrist sizes, has a simple structure, is convenient to adjust, and is highly feasible.

[0067] It is understood that the mechanism proposed in this application is applicable not only to long straps, but also to other types of straps.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0069] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
