Abstract

The embodiment of the application provides a watchband, a watchband assembly, a watch body and a smart watch, and aims to solve the technical problem that the air pump is easy to suck in water drops through the first air inlet, thereby affecting the performance of the smart watch. In the watchband, the first air inlet and the air inlet channel are arranged on the band body, one end of the air inlet channel is communicated with the first air inlet, and the other end of the air inlet channel is communicated with the second air inlet of the air pump. That is, when the air pump works, air is sucked in through the first air inlet on the band body, and the air is delivered to the air bag of the smart watch for blood pressure detection. In this way, the air pump will not suck in water drops in the gap between the band body and the watch body, so as to avoid affecting the blood pressure measurement, and further optimize the performance of the smart watch.

Description

Technical Field

[0001] This application relates to the field of smartwatch technology, specifically to a watch strap, watch strap assembly, watch body, and smartwatch. Background Technology

[0002] As smartwatches become increasingly feature-rich, those with blood pressure measurement capabilities have become widely used. These smartwatches typically consist of a watch body and a strap connected to the body. An air bladder is located on the strap, and an air pump inside the watch body inflates the air bladder. A first air inlet is located near the strap within the watch body. During blood pressure measurement, the air pump can easily draw in water droplets through this first air inlet, affecting the smartwatch's performance. Summary of the Invention

[0003] This application provides a watch strap, a watch strap assembly, a watch body, and a smartwatch, which can prevent water droplets from being drawn into the gap between the watch strap and the watch body through the first air inlet, thereby optimizing the performance of the smartwatch.

[0004] In a first aspect, embodiments of this application provide a watch strap, including: a strap body, on which a first air inlet and an air inlet channel are provided, one end of the air inlet channel being connected to the first air inlet, and the other end of the air inlet channel being used to connect to a second air inlet of an air pump.

[0005] This design features a first air inlet and an air intake channel on the strap. One end of the air intake channel connects to the first air inlet, and the other end connects to the second air inlet of the air pump. In other words, when the air pump is working, it draws in air through the first air inlet on the strap and delivers it to the smartwatch's air bladder for blood pressure monitoring. This design prevents the air pump from drawing in water droplets from gaps between the strap and the watch body (e.g., between the strap and the frame), thus avoiding interference with blood pressure measurement and optimizing the smartwatch's performance. Furthermore, because the first air inlet is located on the strap, even if water droplets enter the first air inlet, they can be removed by wiping or shaking the watch to prevent them from being drawn into the air pump.

[0006] In some embodiments that may include the above embodiments, the strap includes a first strap and a second strap, and the watch body includes a first end and a second end that are disposed generally opposite to each other. The end of the first strap is connected to the first end, and the end of the second strap is connected to the second end. The first strap and the second strap are connected, and the first strap and the second strap can be wrapped around the user's wrist for wearing the smartwatch.

[0007] In some embodiments that may include the above-described embodiments, the first belt is generally set to be relatively long. Correspondingly, the airbag can be set on the inner surface of the first belt and can be set to be relatively large in order to increase the contact area between the airbag and the user's wrist and improve the accuracy of blood pressure detection.

[0008] In some embodiments that may include the above embodiments, the first air inlet and the air inlet channel may be provided on the second belt to avoid the structure of the first belt being too complex and affecting the strength of the first belt.

[0009] In some embodiments that may include the above-described embodiments, the first air inlet is disposed on the outer or inner surface of the strap. The inner surface of the strap is the surface closest to the user's wrist when worn, and the outer surface of the strap is opposite to the inner surface, being the surface away from the user's wrist when worn.

[0010] In an embodiment where the first air inlet is located on the outer surface of the second belt, the air pump can directly draw in outside air through the first air inlet located on the outer surface, which can reduce air flow resistance.

[0011] In an embodiment where the first air inlet is located on the inner surface of the second strap, the first air inlet is not visible from the outside when the watch is worn, which can improve the decorative effect of the strap.

[0012] In some embodiments that may include the above-described embodiments, the first air inlet is disposed on the inner surface of the strap body, and a groove is provided on the inner surface of the strap body. The first air inlet is disposed at the bottom of the groove. It is understood that during the wearing of a smartwatch, the bottom of the groove is generally higher than the opening end of the groove. Even if a water droplet enters the groove through the through hole, it is difficult for the water droplet to contact the bottom of the groove. Therefore, disposing the first air inlet at the bottom of the groove can further prevent the first air inlet from sucking in water droplets, thereby further optimizing the performance of the smartwatch.

[0013] In some embodiments that may include the above-described examples, the bottom of the groove is provided with a protrusion, and the first air inlet is disposed on the protrusion. The protrusion extends from the bottom of the groove toward the inner surface of the second belt, resembling an inverted crater shape. With this configuration, water droplets entering through the through hole will flow along the sidewall of the groove, while the protrusion, protruding from the bottom of the groove, allows the water droplets to flow to the bottom of the groove and accumulate there, preventing water from entering the first air inlet. Furthermore, even if water droplets flow to the bottom of the groove, they will fall off along the surface of the protrusion, further preventing the first air inlet from drawing in water droplets and further optimizing the performance of the smartwatch.

[0014] In some embodiments that may include the above-described embodiments, the depth of the groove is greater than the distance between the lower surface of the protrusion and the bottom of the groove. This arrangement ensures that the end of the protrusion facing away from the bottom of the groove is located inside the groove, that is, maintaining a certain gap between the protrusion and the opening end of the groove, so as to prevent water droplets entering through the through hole from directly entering the first air inlet.

[0015] In some embodiments that may include the above-described embodiments, the depth of the groove can be 0.5mm-2mm (e.g., 0.5mm, 1mm, 2mm, etc.), and the distance between the lower surface of the protrusion and the bottom of the groove is 0-1mm (e.g., 0.5mm, 0.75mm, 1mm, etc.). This setting ensures that there is sufficient gap between the protrusion and the surface of the belt, further preventing water droplets entering through the through hole from directly entering the first air inlet.

[0016] In some embodiments that may include the above-described embodiments, the watch strap further includes a cover plate that covers the first air inlet. The cover plate has at least one through hole communicating with the first air inlet. It is understood that the diameter of the through hole can be smaller than the diameter of the first air inlet to prevent larger particles from entering the first air inlet, thereby avoiding blockage. Furthermore, by covering the first air inlet with the cover plate, it is difficult to observe the first air inlet from the outside, which can improve the decorative effect of the watch strap.

[0017] In some embodiments that may include the above-described embodiments, the material of the cover plate may include metallic materials such as steel, copper, and aluminum. Of course, the material of the cover plate may also include non-metallic materials such as plastic.

[0018] In some embodiments that may include the above-described embodiments, a hydrophobic coating is provided on the surface of the cover plate. This hydrophobic coating may include a hydrophobic paint; for example, the hydrophobic paint may include polyolefins, polycarbonates, polyamides, etc., and this application embodiment does not limit this. With this configuration, the hydrophobic coating has poor affinity for water droplets, and water droplets falling on the cover plate will slide off the surface of the cover plate, thereby preventing water droplets from accumulating on the cover plate and entering the through-hole.

[0019] In some embodiments that may include the above-described embodiments, the watch strap further includes a dustproof mesh covering the first air inlet and disposed between the first air inlet and the cover plate. The dustproof mesh further prevents particulate matter from entering the first air inlet, avoiding blockage. Exemplarily, the dustproof mesh may include metal mesh, nylon mesh, etc., and the materials used for the dustproof mesh are not limited in this application embodiment.

[0020] In some embodiments that may include the above-described examples, the first air inlet is disposed on the side of the strap, which connects the outer and inner surfaces of the strap and is substantially perpendicular to the width direction of the second strap. This arrangement results in a side surface area smaller than the inner and outer surfaces. The first air inlet is less visible from the outside compared to it being disposed on the outer surface, thus improving the strap's decorative effect. Furthermore, compared to it being disposed on the inner surface, the first air inlet directly faces the external environment, reducing air resistance. Additionally, the side surface is less prone to water droplet accumulation, further preventing water droplet inhalation.

[0021] In some embodiments that may include the above-described embodiments, there are multiple first air inlets, which are respectively disposed on a first side and a second side of the belt body; the first side and the second side are disposed opposite to each other along the width direction of the belt body. With this arrangement, the air intake channel is connected to all multiple first air inlets, allowing outside air to simultaneously enter the air intake channel through each first air inlet, reducing resistance to air entering the air intake channel. Furthermore, by providing multiple first air inlets, if one is blocked, air can still enter the air intake channel through the other first air inlets, preventing blood pressure detection failures and improving the robustness of the smartwatch.

[0022] It is understandable that having multiple first air intakes on the first and second sides can be interpreted as having several first air intakes on the first side and several first air intakes on the second side. For example, in an implementation with two first air intakes, one first air intake is provided on the first side and one on the second side. Of course, the number of first air intakes can also be three, four, etc., and correspondingly, both the first and second sides have first air intakes; the number of first air intakes on the first and second sides can be the same or different.

[0023] In some embodiments that may include the above-described embodiments, each of the plurality of first air inlets is connected to the air intake channel through an air guide hole. The first air inlet is connected to the air intake channel through the air guide hole. This arrangement increases the path from the first air inlet to the air intake channel, thereby preventing blockage of the air intake channel.

[0024] In some embodiments that may include the above-described embodiments, the watch strap also includes a dust filter disposed within the air vent. This arrangement allows for air filtration, thereby preventing particulate matter from entering the air intake channel.

[0025] In some embodiments that may include the above-described embodiments, the first air inlet is located near the end of the belt body used for connecting to the gauge body. This arrangement can shorten the distance between the first air inlet and the second air inlet of the air pump, thereby shortening the length of the air intake channel and reducing the flow resistance of air within the air intake channel.

[0026] In some embodiments that may include the above-described embodiments, the watch band further includes an air nozzle, with an air intake channel disposed within the air nozzle. The air nozzle is designed to pass through a mounting hole on the watch body. The air intake channel passes through the air nozzle and communicates with a first air inlet. The watch body has a mounting hole that communicates with a second air inlet of an air pump. By inserting the air nozzle into the mounting hole, communication between the air intake channel and the second air inlet is achieved. When the air pump is operating, it can draw in outside air through the mounting hole, the air intake channel, and the first air inlet, thus preventing the intake of water droplets from the gap between the second band and the watch body and optimizing the performance of the smartwatch.

[0027] In some embodiments that may include the above-described embodiments, the nozzle may be generally cylindrical in shape, and the cross-section of the nozzle along the direction perpendicular to the centerline may be a regular shape such as circular, rectangular, or racetrack-shaped. Of course, the cross-section of the nozzle may also be other irregular shapes. The centerline of the nozzle is arranged approximately parallel to the centerline of the mounting hole. The embodiments of this application do not limit the shape of the nozzle.

[0028] In some embodiments that may include the above-described examples, the watch band further includes a sealing ring. The sealing ring is fitted onto the air nozzle and contacts both the air nozzle and the wall of the mounting hole. The sealing ring achieves a seal between the air nozzle and the mounting hole, further preventing water droplets from being drawn into the gap between the second band body and the middle frame when the air pump is working, thus optimizing the performance of the smartwatch. For example, the sealing ring may be an O-ring.

[0029] In some embodiments that may include the above-described embodiments, an air nozzle is provided on the middle frame, and an air guide channel is provided on the air nozzle, which communicates with the second air inlet and passes through the air nozzle. Correspondingly, a mounting hole is provided at one end (end) of the second gauge body near the middle frame, one end of the air inlet channel communicates with the first air inlet, and the other end of the air inlet channel communicates with the mounting hole; the air nozzle is inserted into the mounting hole, thereby realizing the communication between the air inlet channel and the air guide channel. When the air pump is working, it can draw in outside air through the air guide channel, the mounting hole, the air inlet channel, and the first air inlet.

[0030] Understandably, the air nozzle protrudes from the middle frame, and the second gauge body is recessed to form a mounting hole. The air nozzle extends into the mounting hole to achieve the connection between the second air inlet and the air intake channel.

[0031] In some embodiments that may include the above-described embodiments, the watch strap further includes a metal insert embedded in the strap body, with both the first air inlet and the air inlet channel disposed on the metal insert. Since the material of the second strap body is generally a flexible material such as rubber, the second strap body can deform with the user's wrist during wear, ensuring wearing comfort; the air inlet channel and the first air inlet are disposed on the metal insert to prevent blockage of the air inlet channel and the first air inlet due to deformation of the second strap body.

[0032] Secondly, embodiments of this application also provide a watch strap assembly, including: an airbag and a watch strap as described above, wherein the airbag is disposed on the inner surface of the strap body.

[0033] The watch strap component in this application includes the watch strap in any of the above embodiments, and therefore can achieve the same technical effect and solve the same technical problem.

[0034] Thirdly, this application embodiment also provides a watch body, including: a middle frame, a display panel, an air pump, and a back cover. The middle frame is disposed between the display panel and the back cover. A connecting structure is provided on the middle frame for connecting with the watch strap as described above. The middle frame is also provided with a mounting hole for mounting the air nozzle on the watch strap. The air pump is disposed on the middle frame, and the first air inlet of the air pump is connected to the air inlet channel on the watch strap through the mounting hole.

[0035] In this embodiment of the application, the watch body has a mounting hole for mounting an air nozzle on the watch band, with the air nozzle passing through the mounting hole on the watch body. An air intake channel passes through the air nozzle and communicates with a first air inlet. The mounting hole communicates with a second air inlet of the air pump. The air nozzle passing through the mounting hole enables communication between the air intake channel and the second air inlet. When the air pump is working, it can draw in outside air through the mounting hole, the air intake channel, and the first air inlet, preventing the intake of water droplets from the gap between the second band and the watch body, thus optimizing the performance of the smartwatch.

[0036] In addition, the watch body is provided with a mounting hole that communicates with the second air inlet of the air pump. The watch body can be fitted with watch straps that do not have a first air inlet and air intake channel. In this case, the air pump draws in external air through the mounting hole, meaning that the watch body can be adapted to different types of watch straps, thus improving the watch body's adaptability.

[0037] In some embodiments that may include the above-described embodiments, the connection structure includes a first connection structure and a second connection structure spaced apart, with a mounting hole disposed between the first and second connection structures. Correspondingly, an air nozzle is disposed between a first mating structure and a second mating structure on the second belt body to prevent the air nozzle and the mounting hole from interfering with the connection between the second belt body and the middle frame.

[0038] In some embodiments that may include the above-described examples, the watch body further includes a waterproof component disposed between the mounting hole and the second air inlet. The waterproof component includes a steel sheet, foam, and a waterproof and breathable membrane stacked together. The waterproof and breathable membrane is disposed near the mounting hole, and the steel sheet is connected to the mid-frame. The steel sheet is used to attach the waterproof and breathable membrane to the mid-frame via the foam. The waterproof and breathable membrane allows air to pass through but prevents water from passing through. This design prevents water droplets from the mounting hole from entering the containment space through the waterproof component, further optimizing the performance of the smartwatch.

[0039] Fourthly, embodiments of this application also provide a smartwatch, including: a watch strap as described above and a watch body as described above, wherein the watch strap and the watch body are detachably connected.

[0040] The smartwatch in this application includes the watch strap in any of the above embodiments, and therefore can achieve the same technical effect and solve the same technical problem. Attached Figure Description

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] In the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the positions of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0065] In the embodiments of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0066] In this application embodiment, the term "connection" or "linking" should be interpreted broadly. For example, "connection" can be a fixed connection, an electrical connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. In related technologies, a smartwatch includes a watch body and a watch band. The watch band is connected to the watch body, and an air bladder is provided on the inner surface of the watch band. An air pump is provided inside the watch body, and the air outlet of the air pump is connected to the air bladder. A first air inlet is provided in the watch body near the watch band, and the first air inlet is connected to a second air inlet of the air pump. During measurement, the air pump draws in air through the gap between the end of the watch band and the watch body and the first air inlet, and delivers the air to the air bladder. After the air bladder inflates, it compresses the wrist artery to measure blood pressure. However, the gap between the end of the watch band and the watch body easily accumulates sweat or rainwater. During measurement, the air pump can easily draw in water droplets from this gap through the first air inlet, affecting blood pressure measurement (such as measurement pause, measurement failure, inaccurate measurement results, inability to measure for a period of time, etc.), thereby affecting the performance of the smartwatch.

[0067] Please refer to Figure 1 This application provides a smartwatch, which includes a watch body 10 and a watch band assembly 20. The watch band assembly 20 includes a watch band 30, which is connected to the watch body 10. When worn, the watch band 30 wraps around the user's wrist to fix the watch body 10 to the user's wrist.

[0068] In this embodiment, the watch strap 30 includes a strap body 310 connected to the watch body 10. In some examples, the strap body 310 includes a first strap body 319 and a second strap body 320. The watch body 10 includes a first end 105 and a second end 106 disposed generally opposite to each other. The end of the first strap body 319 is connected to the first end 105, and the end of the second strap body 320 is connected to the second end 106. The first strap body 319 and the second strap body 320 are connected, and the first strap body 319 and the second strap body 320 can be wrapped around the user's wrist for wearing a smartwatch.

[0069] In some implementations, the table body 10 can be roughly cylindrical, cuboid, or other regular shapes. Of course, the table body 10 can also be other irregular shapes, and this application embodiment does not limit this.

[0070] In this application, the first end 105 and the second end 106 can be arranged along the line connecting six o'clock to twelve o'clock. The first end 105 can be arranged closer to six o'clock, and correspondingly, the second end 106 can be arranged closer to twelve o'clock; or, the first end 105 can be arranged closer to twelve o'clock, and correspondingly, the second end 106 can be arranged closer to six o'clock. This application embodiment does not limit this.

[0071] Please refer to Figure 2The first strap 319 and the second strap 320 can be connected by a locking device 316. The locking device 316 may include a locking ring 3161 and a locking pin 3162. The locking ring 3161 is located at the end of the second strap 320 away from the end, and the locking pin 3162 is connected to the locking ring 3161. Multiple locking holes 318 are spaced apart along the length of the first strap 319. When worn, the first strap 319 passes through the locking ring 3161, and the locking pin 3162 passes through one of the locking holes 318, thus preventing the first strap 319 and the second strap 320 from separating, allowing the first strap 319 and the second strap 320 to wrap around the user's wrist. It is understood that by having the locking pin 3162 pass through different locking holes 318, the size of the space enclosed by the first strap 319 and the second strap 320 can be adjusted to accommodate users of different body types (different wrist sizes), improving the adaptability of the smartwatch.

[0072] Of course, in other implementations, the first strap 319 and the second strap 320 can also be connected by hook and loop fasteners (not shown). The hook and loop fasteners include a first connecting piece and a second connecting piece. The first connecting piece can be provided with soft fibers, and the second connecting piece can be provided with barbs. The first connecting piece can be provided on the first strap 319, and the second connecting piece can be provided on the second strap 320. In use, the first strap 319 and the second strap 320 are wrapped around the user's wrist, and part of the first strap 319 covers the second strap 320, or part of the second strap 320 covers the first strap 319, so that the first connecting piece is attached to the second connecting piece. At this time, the barbs hook onto the fibers, which can maintain the connection between the first connecting piece and the second connecting piece, thereby realizing the connection between the first strap 319 and the second strap 320.

[0073] In this embodiment, the watch strap 30 is detachably connected to the watch body 10. This design facilitates the removal and installation of the watch strap 30 and the watch body 10. Users can connect watch straps 30 of different colors and / or materials to the watch body 10 to improve the decorative effect of the smartwatch and enhance the user experience.

[0074] Figure 3 for Figure 1 The diagram shows the structural structure of the watch body in the smartwatch. Figure 4a for Figure 1 The image shows a partial view of the end of the second strap in the smartwatch. Figure 4b for Figure 1 Please refer to the partial view of the end of the second band in the smartwatch shown from another perspective. Figure 3 , Figure 4a as well as Figure 4bIn some examples, the watch body 10 is provided with a connecting structure 1021, and correspondingly, the watch strap 30 is provided with a mating structure 334 at one end (end) near the watch body 10. The mating structure 334 is detachably connected to the connecting structure 1021 to realize a detachable connection between the watch body 10 and the watch strap 30.

[0075] In the implementation of the belt body 310 including a first belt body 319 and a second belt body 320, the connecting structure 1021 may include a connecting hole provided on the second end 106 of the watch body 10, with a stop portion provided inside the connecting hole. Correspondingly, the mating structure 334 may include a hook portion provided at the end of the second belt body 320, the hook portion extending into the connecting hole and hooking onto the stop portion to achieve the connection between the connecting structure 1021 and the mating structure 334. Alternatively, the connecting structure 1021 may include a first magnet provided on the second end 106 of the watch body 10. Correspondingly, the mating structure 334 may include a second magnet provided at the end of the second belt body 320. The first magnet and the second magnet attract each other, thereby achieving the connection between the connecting structure 1021 and the mating structure 334. This application embodiment does not limit the connecting structure 1021 and the mating structure 334.

[0076] In one implementation, the connecting structure 1021 includes a first connecting structure 1022 and a second connecting structure 1023, which are spaced apart on the second end 106. Correspondingly, the mating structure 334 on the second belt 320 includes a first mating structure 3341 and a second mating structure 3342. The first mating structure 3341 is connected to the first connecting structure 1022, and the second mating structure 3342 is connected to the second connecting structure 1023 to improve the connection force between the second belt 320 and the watch body 10.

[0077] It is understood that the above description uses the example of connection structure 1021 including two connection structures and corresponding mating structure 334 including two mating structures. However, the embodiments of this application are not limited to this. The number of connection structures 1021 can be more or less, and correspondingly, the number of mating structures 334 can also be more or less. When multiple connection structures 1021 are included, different connection structures 1021 can adopt the same structural design or different structural designs. When multiple mating structures 334 are included, different mating structures 334 can adopt the same structural design or different structural designs.

[0078] It is understandable that the connection method between the first strip body 319 and the middle frame 102 is roughly the same as the connection method between the second strip body 320 and the middle frame 102, and will not be described in detail here. Alternatively, the connection method between the first strip body 319 and the middle frame 102 may be different from that of the second strip body 320.

[0079] It should be noted that the above description uses the connection between the first strap 319 and the middle frame 102 as an example to illustrate the connection of the strap 310 to the watch body 10, but the embodiments of this application are not limited to this. For example, the watch body 10 includes a middle frame and a back cover, and the first strap 319 and the second strap 320 can be connected to the back cover. Alternatively, the watch body 10 may include a front cover and a back cover, with a display panel embedded in the front cover, and the back cover and the front cover connected to form a closed accommodating space. The first strap 319 and the second strap 320 can be connected to the front cover, can be connected to the back cover, or can be connected to both the front cover and the back cover.

[0080] It is understood that the above description uses the example of setting the mating structure 334 on the second belt 320 as an example. However, it is understood that the embodiments of this application are not limited to this. For example, the mating structure 334 can also be set on the first belt 319. The number of mating structures 334 can be one or more, and the number of mating structures 334 can be the same as the number of connecting structures 1021.

[0081] Figure 5 for Figure 1 Sectional view along the AA direction. Figure 6 for Figure 5 Please refer to the enlarged view of part A in the middle. Figure 1 , Figure 5 and Figure 6 In some embodiments, the material of the strap 310 may include rubber, which has good flexibility and can improve the user's wearing comfort. Correspondingly, the strap 30 may also include a metal insert 323, which is embedded in the strap 310 and cooperates with the structure 334 (…). Figure 4a As shown, the metal insert 323 can be disposed on the metal insert 323, which facilitates the connection between the mating structure 334 and the belt 310, and also improves the connection force between the mating structure 334 and the belt 310. Exemplarily, the material of the metal insert 323 may include metal materials such as copper, aluminum, and steel; this application embodiment does not limit this. It should be noted that the metal insert 323 can also be made of non-metallic materials; correspondingly, non-metallic inserts are made of non-metallic materials. Both the non-metallic insert and the metal insert 323 can be collectively referred to as the headpiece.

[0082] It is understood that in the implementation of the belt body 310 including the first belt body 319 and the second belt body 320, the end of the first belt body 319 near the first end 105 and the end of the second belt body 320 near the second end 106 can both be provided with metal inserts 323, so as to facilitate the connection between the first belt body 319 and the second belt body 320 and the watch body 10.

[0083] Continue to refer to Figure 5 and Figure 6In this embodiment, the watch body 10 may further include a middle frame 102, a display panel 101, a back cover 104, a motherboard, and a battery. The middle frame 102 forms an accommodating space 103, the display panel 101 covers one side of the middle frame 102, and the back cover 104 covers the other side of the middle frame 102 to enclose the accommodating space 103. The motherboard and the battery are both disposed within the accommodating space 103. The motherboard is electrically connected to both the battery and the display panel 101. The battery can power the motherboard, and the motherboard can control the display panel 101 to display time, images, or control information, etc. It is understood that the display panel 101 is disposed on the side of the middle frame 102 away from the user's wrist to facilitate the user's viewing of the display panel 101 and touch control.

[0084] In this embodiment of the application, the watch strap assembly 20 also includes an airbag 40 (e.g., Figure 1 As shown, the airbag 40 is disposed on the inner surface of the strap 310. The inner surface of the strap 310 is the surface that is close to the user's wrist when worn, the outer surface of the strap 310 is opposite to the inner surface of the strap 310, and the outer surface of the strap 310 is the surface that is away from the user's wrist when worn.

[0085] In the above implementation, the watch body 10 also includes an air pump and a pressure detection device. The air pump can be installed within the accommodating space 103. The air pump is electrically connected to the main board, and its outlet is connected to the air bladder 40. The pressure detection device is electrically connected to the main board and is used to detect the pressure inside the air bladder 40. During use, the smartwatch can be controlled to perform blood pressure detection via the control information on the display panel 101. Correspondingly, the main board controls the air pump to operate, supplying air to the air bladder 40 to inflate it and compress the wrist artery. The pressure detection device can detect the pressure inside the air bladder 40. The main board can obtain the user's systolic blood pressure, diastolic blood pressure, pulse, and other information based on the pressure changes in the air bladder 40 obtained by the pressure detection device, and control the display panel 101 to display this information to achieve blood pressure detection.

[0086] In some implementations, the strap 310 includes a first strap 319 and a second strap 320. The first strap 319 is connected to one end of the middle frame 102, and the second strap 320 is connected to the other end of the middle frame 102. The locking device 316 is connected to the first end of the second strap 320. In order to increase the adjustment range of the space enclosed by the first strap 319 and the second strap 320, the first strap 319 is generally set to be longer. Correspondingly, the airbag 40 can be set on the inner surface of the first strap 319. A larger airbag 40 can be set to increase the contact area between the airbag 40 and the user's wrist and improve the accuracy of blood pressure detection.

[0087] Continue to refer to Figure 5 and Figure 6In this embodiment, the belt 310 is provided with a first air inlet 321 and an air inlet channel 322. One end of the air inlet channel 322 is connected to the first air inlet 321, and the other end of the air inlet channel 322 is connected to the second air inlet of the air pump. That is, when the air pump is working, it draws in air through the first air inlet 321 on the belt 310 and delivers the air to the airbag 40 (e.g., ...). Figure 1 (As shown), this is used for blood pressure detection. This configuration prevents the air pump from drawing in water droplets from the gap between the strap 310 and the watch body, thus avoiding interference with blood pressure measurement (e.g., preventing measurement pauses, failures, inaccurate results, or inability to measure for a period of time), thereby optimizing the smartwatch's performance. Furthermore, since the first air inlet 321 is located on the strap 310, even if water droplets enter the first air inlet 321, they can be removed by wiping or shaking to prevent them from being drawn into the air pump.

[0088] In this embodiment, the end of the second band 320 is close to the watch body 10, and the first air inlet 321 draws in air through the gap between the second band 320 and the watch body 10. It is understood that the second band 320 being close to the watch body 10 can mean that the second band 320 is close to the middle frame 102, or close to the front cover or rear cover; correspondingly, the gap between the second band 320 and the watch body 10 can be a gap between the second band 320 and the middle frame 102, or a gap between the second band 320 and structures such as the front cover or rear cover in the watch body 10. This embodiment does not limit this.

[0089] In some implementations, the belt body 310 includes a first belt body 319 and a second belt body 320. The airbag 40 is disposed on the inner surface of the first belt body 319. Correspondingly, the first air inlet 321 and the air inlet channel 322 can be disposed on the second belt body 320 to avoid the structure of the first belt body 319 being too complex and affecting the strength of the first belt body 319.

[0090] The following description will be based on the example of an airbag 40 being disposed on the inner surface of the first belt 319, and the first air inlet 321 and the air inlet channel 322 being disposed on the second belt 320. It is understood that the embodiments of this application do not limit this, and the first air inlet 321 and the air inlet channel 322 may also be disposed on the first belt 319.

[0091] Continue to refer to Figure 5 and Figure 6 In some embodiments, the first air inlet 321 can be located on the outer surface 312 of the second belt 320. With this configuration, the air pump can directly draw in outside air through the first air inlet 321 located on the outer surface 312, which can reduce air flow resistance.

[0092] In some implementations, the first air inlet 321 is located near one end (end) of the second belt 320 used to connect to the meter body 10. That is, the first air inlet 321 is located on the outer surface 312 of the second belt 320 near the middle frame 102. This arrangement can shorten the distance between the first air inlet 321 and the second air inlet of the air pump, thereby shortening the length of the air intake channel 322 and reducing the flow resistance of air in the air intake channel 322.

[0093] In the implementation of the watch band including the metal insert 323, the metal insert 323 is embedded in the second band body 320, and the air intake channel 322 and the first air intake 321 can be set on the metal insert 323. Since the material of the second band body 320 is generally a material with a certain degree of flexibility, such as rubber, the second band body 320 can deform with the user's wrist during wearing, ensuring wearing comfort; the air intake channel 322 and the first air intake 321 are set on the metal insert 323, which can prevent the air intake channel 322 and the first air intake 321 from being blocked due to the deformation of the second band body 320.

[0094] In the above implementation, a window can be provided on the outer surface 312 of the second belt 320 to expose the first air inlet 321 so that outside air can enter the first air inlet 321.

[0095] In some examples, the watch strap also includes a cover plate 327 that covers the first air inlet 321. The cover plate 327 has at least one through-hole 329 communicating with the first air inlet 321, allowing outside air to enter the air intake channel 322 through the through-hole 329 and the first air inlet 321. It is understood that the diameter of the through-hole 329 can be smaller than the diameter of the first air inlet 321 to prevent larger particles from entering the first air inlet 321, thus avoiding blockage. Furthermore, by covering the first air inlet 321 with the cover plate 327, the first air inlet 321 is difficult to observe from the outside, which can improve the decorative effect of the watch strap.

[0096] For example, the material of the cover plate 327 may include metal materials such as steel, copper, and aluminum. Of course, the material of the cover plate 327 may also include non-metallic materials such as plastic. This application embodiment does not limit this.

[0097] In the implementation where a window is provided on the outer surface 312 of the second strap body 320, the cover plate 327 can be accommodated within the window to prevent the cover plate 327 from protruding from the outer surface 312 of the second strap body 320, thereby further improving the decorative effect of the watch strap. It should be noted that, as... Figure 5 and Figure 6The window shown is merely an example, and the embodiments of this application are not limited thereto. Those skilled in the art can set the size, shape, etc. of the window as needed.

[0098] In the above implementation, a hydrophobic coating is provided on the surface of the cover plate 327. This hydrophobic coating may include a hydrophobic paint. For example, the hydrophobic paint may include polyolefin, polycarbonate, polyamide, etc., and this application embodiment does not limit this. With this configuration, the hydrophobic coating has poor affinity with water droplets, and water droplets falling on the cover plate 327 will slide off the surface of the cover plate 327, thereby preventing water droplets from accumulating on the cover plate 327 and entering the through hole 329.

[0099] In some embodiments, the watch strap further includes a dustproof mesh 328, which covers the first air inlet 321 and is disposed between the first air inlet 321 and the cover plate 327. This arrangement further prevents particulate matter from entering the first air inlet 321, avoiding blockage. Exemplarily, the dustproof mesh 328 may include a metal mesh, nylon mesh, etc., and the material of the dustproof mesh 328 is not limited in this embodiment. It should be noted that the above is only an example, and the dustproof mesh 328 can also be disposed in other locations.

[0100] In the implementation of providing a window on the outer surface 312 of the second strap body 320, the cover plate 327 and the dustproof net 328 can both be set inside the window to prevent the cover plate 327 from protruding from the outer surface 312 of the strap body and improve the decorative effect of the strap.

[0101] In other embodiments, the watch strap may include a dust filter 328, but the watch strap does not include a cover plate 327. In this case, the dust filter 328 covers the first air inlet 321 to serve as a filter, thereby preventing the first air inlet 321 from being blocked.

[0102] Continue to refer to Figure 5 and Figure 6 In the above embodiments, the watchband also includes an air nozzle 324, with an air inlet channel 322 disposed within the air nozzle 324. The air nozzle 324 is used to pass through the mounting hole 108 on the watch body 10. For example, the air nozzle 324 can be disposed at one end (end) of the second band 320 near the middle frame 102. The air inlet channel 322 passes through the air nozzle 324 and communicates with the first air inlet 321. The watch body 10 is provided with a mounting hole 108 communicating with the second air inlet of the air pump. The air nozzle 324 passes through the mounting hole 108, thus achieving communication between the air inlet channel 322 and the second air inlet. When the air pump is working, it can draw in outside air through the mounting hole 108, the air inlet channel 322, and the first air inlet 321, preventing the intake of water droplets from the gap between the second band 320 and the watch body 10, thereby optimizing the performance of the smartwatch.

[0103] It is understandable that the watch body 10 is provided with a mounting hole 108 that communicates with the second air inlet of the air pump. The watch body 10 can be fitted with watch straps that do not have a first air inlet 321 and an air inlet channel 322. At this time, the air pump draws in external air through the mounting hole 108, that is, the watch body 10 can be adapted to different types of watch straps, thus improving the adaptability of the watch body 10.

[0104] Understandably, the air nozzle 324 protrudes from the watch strap, and the watch body 10 is recessed to form a mounting hole 108. The air nozzle 324 extends into the mounting hole 108 to achieve communication between the second air inlet and the air intake channel 322.

[0105] In the implementation of the watch band including the metal insert 323, the air nozzle 324 can be integrated with the metal insert 323 to simplify the structure of the watch band. Of course, the air nozzle 324 can also be connected to the metal insert 323 by welding or bolting. This application embodiment does not limit this.

[0106] like Figure 3 As shown, in the implementation where a first connecting structure 1022 and a second connecting structure 1023 are spaced apart on the second end 106 of the middle frame 102, the mounting hole 108 can be located between the first connecting structure 1022 and the second connecting structure 1023. Correspondingly, as... Figure 4a As shown, the air nozzle 324 can be positioned between the first mating structure 3341 and the second mating structure 3342 on the second belt body 320 to prevent the air nozzle 324 and the mounting hole 108 from affecting the connection between the second belt body 320 and the middle frame 102. It is understood that the embodiments of this application are not limited to this, and the air nozzle 324 and the mounting hole 108 can also be positioned in other locations.

[0107] Continue to refer to Figure 5 and Figure 6 In some implementations, the watch body 10 also includes a waterproof component 107, which is disposed between the mounting hole 108 and the second air inlet of the air pump. The waterproof component 107 can be disposed within the accommodating space 103. The waterproof component 107 includes a steel sheet, foam, and a waterproof and breathable membrane stacked together. The waterproof and breathable membrane is disposed near the mounting hole 108, and the steel sheet is connected to the middle frame 102. The steel sheet is used to attach the waterproof and breathable membrane to the middle frame 102 through the foam. The waterproof and breathable membrane allows air to pass through, but prevents water from passing through. This configuration prevents water droplets from the mounting hole 108 from entering the accommodating space 103 via the waterproof component 107, further optimizing the performance of the smartwatch.

[0108] In some examples, the middle frame 102 has a hole 332 communicating with the mounting hole 108, and a waterproof and breathable membrane covers the hole 332 to prevent water droplets from the mounting hole 108 from entering the receiving space 103. In other examples, the waterproof and breathable membrane may cover the end of the mounting hole 108 facing the receiving space 103, which can also prevent water droplets from the mounting hole 108 from entering the receiving space 103.

[0109] In some implementations, a dustproof mesh 328 is also provided inside the mounting hole 108. The dustproof mesh 328 is located between the air nozzle 324 and the waterproof component 107. With this arrangement, the dustproof mesh 328 can further filter the air and prevent the waterproof component 107 from being blocked. In addition, the dustproof mesh 328 can prevent external particles from entering when the body 10 is separated from the second belt 320, so as not to block the waterproof component 107.

[0110] Please refer to Figure 7 and Figure 8 In other embodiments, a nozzle 324 is provided on the middle frame 102, and an air guide channel 109 communicating with the second air inlet is provided on the nozzle 324, the air guide channel passing through the nozzle 324. Correspondingly, a mounting hole 108 is provided at one end (end) of the second belt body 320 near the middle frame 102, one end of the air inlet channel 322 communicating with the first air inlet 321, and the other end of the air inlet channel 322 communicating with the mounting hole 108; the nozzle 324 passes through the mounting hole 108, thereby realizing the communication between the air inlet channel 322 and the air guide channel 109. When the air pump is working, it can draw in outside air through the air guide channel 109, the mounting hole 108, the air inlet channel 322 and the first air inlet 321.

[0111] It is understandable that the air nozzle 324 protrudes from the middle frame, and the second belt body 320 is recessed to form a mounting hole 108. The air nozzle 324 extends into the mounting hole 108 to achieve the connection between the second air inlet and the air intake channel 322.

[0112] In the implementation of the watch strap including the metal insert 323, the mounting hole 108 can be provided on the metal insert 323 to simplify the structure of the watch strap.

[0113] Continue to refer to Figure 7 and Figure 8In some implementations, the watch body 10 also includes a waterproof component 107. The mid-frame 102 has holes 332 communicating with the air vent 109. The waterproof component 107 can be disposed within the accommodating space 103. The waterproof component 107 includes a layered steel sheet, foam, and a waterproof breathable membrane. The waterproof breathable membrane covers the holes 332. The steel sheet is connected to the mid-frame 102 and is used to attach the waterproof breathable membrane to the mid-frame 102 via the foam. The waterproof breathable membrane allows air to pass through but prevents water from passing through. This design prevents water droplets from entering the accommodating space 103 via the waterproof component 107, further optimizing the smartwatch's performance. It should be noted that the above embodiment uses a steel sheet as an example; it is understood that other materials can also be used.

[0114] In some implementations, a dustproof net 328 is also provided in the air duct 109. With this arrangement, the dustproof net 328 can further filter the air and prevent clogging of the waterproof component 107. In addition, the dustproof net 328 can prevent external particles from entering when the surface body 10 is separated from the second belt body 320, so as not to clog the waterproof component 107.

[0115] Continue to refer to Figure 6 and Figure 8 In the above embodiments, the shape of the air nozzle 324 can be approximately cylindrical, and the cross-section of the air nozzle 324 along the direction perpendicular to the center line can be a regular shape such as circular, rectangular, or racetrack-shaped. Of course, the cross-section of the air nozzle 324 can also be other irregular shapes. The center line of the air nozzle 324 is arranged approximately parallel to the center line of the mounting hole 108. The shape of the air nozzle 324 is not limited in this application embodiment.

[0116] For example, the watch band also includes a sealing ring 325, which is fitted onto the air nozzle 324 and contacts both the air nozzle 324 and the wall of the mounting hole 108. The sealing ring 325 can achieve a seal between the air nozzle 324 and the mounting hole 108, which can further prevent water droplets from being sucked into the gap between the second band body 320 and the middle frame 102 when the air pump is working, thus optimizing the performance of the smartwatch.

[0117] Unlike the embodiments described above, in other embodiments, please refer to... Figures 9-11 ,in, Figure 10 for Figure 9 Sectional view along the BB direction. Figure 11 for Figure 10 The enlarged view at point C shows that the first air inlet 321 can be set on the inner surface 311 of the second strap 320. With this setting, the first air inlet 321 will not be visible from the outside when worn, which can improve the decorative effect of the strap.

[0118] In some implementations, the first air inlet 321 is located near one end (end) of the second belt 320 used to connect to the instrument body 10. That is, the first air inlet 321 is located on the inner surface 311 of the second belt 320 near the middle frame 102. This arrangement can shorten the distance between the first air inlet 321 and the second air inlet of the air pump, thereby shortening the length of the air intake channel 322 and reducing the flow resistance of air in the air intake channel 322.

[0119] In the implementation of the watch band including the metal insert 323, the metal insert 323 is embedded in the second band body 320, and the air intake channel 322 and the first air intake 321 can be set on the metal insert 323. Since the material of the second band body 320 is generally a material with a certain degree of flexibility, such as rubber, the band body can deform with the user's wrist during wearing, ensuring wearing comfort; the air intake channel 322 and the first air intake 321 are set on the metal insert 323, which can prevent the air intake channel 322 and the air intake from being blocked due to the deformation of the second band body 320.

[0120] In the above implementation, a window may be provided on the inner surface 311 of the second belt 320 to expose the first air inlet 321 so that outside air can enter the first air inlet 321.

[0121] like Figure 12 , Figure 13a as well as Figure 13b As shown, in some examples, the watch band also includes a cover 327 that covers the first air inlet 321 (e.g., Figure 11 As shown, the cover plate 327 has at least one through hole 329, which communicates with the first air inlet 321, allowing outside air to enter the air intake channel 322 through the through hole 329 and the first air inlet 321. It is understood that the diameter of the through hole 329 can be smaller than the diameter of the first air inlet 321, so that the cover plate 327 can block larger particles from entering the first air inlet 321, thereby preventing the first air inlet 321 from being blocked. On the other hand, by covering the first air inlet 321 with the cover plate 327, the first air inlet 321 is difficult to observe from the outside, which can improve the decorative effect of the watch strap.

[0122] For example, the material of the cover plate 327 may include metal materials such as steel, copper, and aluminum. Of course, the material of the cover plate 327 may also include non-metallic materials such as plastic. This application embodiment does not limit this.

[0123] In the implementation of the window on the inner surface 311 of the second strap body 320, the cover plate 327 can be accommodated in the window to prevent the cover plate 327 from protruding from the inner surface 311 of the second strap body 320. That is, the cover plate 327 is roughly flush with the inner surface 311, which can further improve the decorative effect and comfort of the strap.

[0124] In the above implementation, a hydrophobic coating is provided on the surface of the cover plate 327. This hydrophobic coating may include a hydrophobic paint. For example, the hydrophobic paint may include polyolefin, polycarbonate, polyamide, etc., and this application embodiment does not limit this. With this configuration, the hydrophobic coating has poor affinity with water droplets, and water droplets (such as sweat or water droplets from hand washing) between the cover plate 327 and the user's skin will not accumulate on the cover plate 327, thereby preventing water droplets from entering the through hole 329.

[0125] Continue to refer to Figure 10 and Figure 11 In some embodiments, the watch strap further includes a dustproof mesh 328, which covers the first air inlet 321 and is disposed between the first air inlet 321 and the cover plate 327. This arrangement further prevents particulate matter from entering the first air inlet 321, thus avoiding blockage. Exemplarily, the dustproof mesh 328 may include a metal mesh, nylon mesh, etc., and the materials used for the dustproof mesh 328 are not limited in this application embodiment.

[0126] In the implementation of providing a window on the inner surface 311 of the second strap body 320, the cover plate 327 and the dustproof net 328 can both be set inside the window to prevent the cover plate 327 from protruding from the inner surface 311 of the second strap body 320, thereby improving the decorative effect and comfort of the strap.

[0127] In other embodiments, the watch strap may include a dust filter 328, but the watch strap does not include a cover plate 327. In this case, the dust filter 328 covers the first air inlet 321 to serve as a filter, thereby preventing the first air inlet 321 from being blocked.

[0128] Continue to refer to Figure 11 In some embodiments, a groove 330 is provided on the inner surface 311 of the second strap 320, and the first air inlet 321 is located at the bottom of the groove 330. It is understood that during the wearing of the smartwatch, the bottom of the groove is generally higher than the opening end of the groove 330. Figure 11 Even if water droplets enter the groove 330 through the through hole 329, it is difficult for the water droplets to contact the bottom of the groove 330. Therefore, the first air inlet 321 is set at the bottom of the groove 330, which can further prevent the first air inlet 321 from sucking in water droplets and further optimize the performance of the smartwatch.

[0129] In some examples, the bottom of the groove 330 is provided with a protrusion 331, and the first air inlet 321 is provided on the protrusion 331. That is, the air intake channel 322 passes through the protrusion 331 and communicates with the first air inlet 321. The protrusion 331 protrudes from the bottom of the groove towards the inner surface 311 of the second belt 320, similar to the shape of an inverted volcano. With this configuration, water droplets entering through the through hole 329 will flow along the side wall of the groove 330, while the protrusion 331 protrudes from the bottom of the groove 330, allowing the water droplets to flow to the bottom of the groove 330 and accumulate there, preventing water from entering the first air inlet 321. In addition, even if water droplets flow to the bottom of the groove 330, they will fall off the surface of the protrusion 331, further preventing the first air inlet 321 from sucking in water droplets, thus further optimizing the performance of the smartwatch.

[0130] In the above implementation, the depth L1 of the groove 330 is greater than the distance L2 between the lower surface of the protrusion 331 and the bottom of the groove 330. The depth L1 of the groove 330 is the minimum distance between the bottom of the groove 330 and the inner surface 311. This arrangement ensures that the end of the protrusion 331 facing away from the bottom of the groove 330 is located inside the groove 330, maintaining a certain gap between the protrusion 331 and the opening end of the groove 330 to prevent water droplets entering through the through hole 329 from directly entering the first air inlet 321.

[0131] For example, the depth of the groove 330 can be 0.5mm-2mm (e.g., 0.5mm, 1mm, 2mm, etc.), and the distance between the lower surface of the protrusion 331 and the bottom of the groove 330 is 0-1mm (e.g., 0.5mm, 0.75mm, 1mm, etc.). This configuration ensures sufficient clearance between the protrusion 331 and the surface of the belt, further preventing water droplets entering through the through hole 329 from directly entering the first air inlet 321.

[0132] Unlike the embodiments described above, in some embodiments, Figure 15a for Figure 14 A partial view from the perspective of the second volume in the middle. Figure 15b for Figure 14 For a partial view of the second zone from another perspective, please refer to [reference needed]. Figure 14 , Figure 15a as well as Figure 15bThe first air inlet 321 is located on the side 313 of the second strap 320. The side 313 connects the outer surface 312 and the inner surface 311 of the second strap 320, and is approximately perpendicular to the width direction of the second strap 320. This arrangement results in a smaller area for the side 313 compared to the inner surface 311 and the outer surface 312. The first air inlet 321 is less visible from the outside compared to the side 312, thus improving the strap's aesthetic appeal. Furthermore, the side 313 position reduces air resistance compared to the inner surface 311, allowing for better water droplet accumulation and further optimizing the smartwatch's performance.

[0133] Figure 16 for Figure 14 Sectional view along the CC direction. Figure 17 for Figure 16 A magnified view of a section at point D. Figure 18 for Figure 14 For the sectional view along the DD direction, please refer to... Figures 16-18 In some embodiments, the first air inlet 321 is disposed near one end (end) of the second belt 320 for connecting the gauge body 10. That is, the first air inlet 321 is disposed on the side 313 of the second belt 320 near the middle frame 102. This arrangement can shorten the distance between the first air inlet 321 and the second air inlet of the air pump, thereby shortening the length of the air intake channel 322 and reducing the air flow resistance in the air intake channel 322.

[0134] Continue to refer to Figure 18 In some embodiments, there are multiple first air inlets 321. Correspondingly, the side surface 313 includes a first side surface 314 and a second side surface 315 disposed opposite each other along the width direction of the belt body. The multiple first air inlets 321 are respectively disposed on the first side surface 314 and the second side surface 315 of the second belt body 320. With this configuration, the air intake channel 322 is connected to all multiple first air inlets 321, and outside air can simultaneously enter the air intake channel 322 through each first air inlet 321, which can reduce the resistance of air entering the air intake channel 322. On the other hand, by providing multiple first air inlets 321, if one of them is blocked, air can enter the air intake channel 322 through the other first air inlets 321, which can avoid blood pressure detection failure and improve the robustness of the smartwatch.

[0135] It is understandable that multiple first air inlets 321 are respectively provided on the first side 314 and the second side 315. This can be understood as the first side 314 having several first air inlets 321, and the second side 315 also having several first air inlets 321. For example, in an implementation where the number of first air inlets 321 is two, the first side 314 has one first air inlet 321, and the second side 315 also has one first air inlet 321. Of course, the number of first air inlets 321 can also be three, four, etc., and correspondingly, both the first side 314 and the second side 315 have first air inlets 321. The number of first air inlets 321 on the first side 314 and the second side 315 can be the same or different.

[0136] In the above implementation, the second belt 320 is also provided with an air guide hole 333. One end of the air guide hole 333 is connected to the air intake channel 322, and the other end of the air guide hole 333 is connected to the first air intake port 321. That is to say, the first air intake port 321 is connected to the air intake channel 322 through the air guide hole 333. This arrangement can increase the path from the first air intake port 321 to the air intake channel 322, thereby avoiding blockage of the air intake channel 322.

[0137] In embodiments where there are multiple first air inlets 321, there are also multiple air guide holes 333, with each first air inlet 321 connected to the air intake channel 322 via an air guide hole 333. In some embodiments, the watch strap further includes a dust filter 328 disposed within the air guide hole 333. This arrangement allows for air filtration, thereby preventing particulate matter from entering the air intake channel 322. Exemplarily, the dust filter 328 may include a metal mesh or a nylon mesh, etc., and this application embodiment does not limit this.

[0138] It should be noted that in the above embodiments, the example of providing a first air inlet 321 on the outer surface 312, the inner surface 311, or the side surface 313 is used for illustration. It can be understood that the first air inlet 321 can also be provided on the outer surface 312 and the inner surface 311, or on the outer surface 312 and the side surface 313, or on the inner surface 311 and the side surface 313, or on the outer surface 312, the inner surface 311, and the side surface 313. In some examples, there are multiple first air inlets 321, and the multiple first air inlets 321 can be respectively provided on at least one of the outer surface 312, the inner surface 311, and the side surface 313.

[0139] The above description is merely a specific implementation of the embodiments of this application, but the protection scope of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
