Description

Technical Field

[0001] This invention relates to the field of cable retraction technology, and more particularly to a cable retraction mechanism and a wearable electronic device. Background Technology

[0002] Wearable electronic devices include a device body and a strap. In related technologies, the strap includes a first strap body and a second strap body. The first strap body has a loop fastener, and the second strap body has a hook fastener. Therefore, when wearing the wearable electronic device, the user can adjust the strap to a suitable length by adjusting the attachment positions of the loop fastener and hook fastener, thus ensuring the wearable electronic device fits snugly around the user's head and preventing it from slipping off. However, in related technologies, during the attachment of the loop fastener and hook fastener, misalignment may occur, causing the fastener to stick to the hair and pull on it. Therefore, the strap in related technologies has the problem of being inconvenient to adjust in length. Summary of the Invention

[0003] This invention provides a cable retraction mechanism and a wearable electronic device, which can solve the problem that the straps are not easy to adjust in length.

[0004] To solve the above-mentioned technical problems, the present invention is implemented as follows: In a first aspect, embodiments of the present invention provide a cable retraction mechanism.

[0005] The cable retraction mechanism provided in this embodiment of the invention includes: a base, a slide, a first rotating wheel, and a cable; the slide is slidably connected to the base, the first rotating wheel is rotatably connected to the slide, the cable includes a first connecting segment and a second connecting segment connected to each other, the first connecting segment is wrapped around the side of the first rotating wheel opposite to the second connecting segment, the first connecting segment is connected to the slide through the first rotating wheel, and the second connecting segment is the part of the cable extending out of the base; the slide slides relative to the base between a first position and a second position to adjust the length of the second connecting segment of the cable extending out of the base.

[0006] In some embodiments, both ends of the cable are fixed to the base, with the first position close to the second connecting segment and the second position far from the second connecting segment; during the process of the slide relative to the base from the first position to the second position, the slide drives the cable to move towards the second position through the first rotating wheel, thereby shortening the length of the second connecting segment.

[0007] In some embodiments, the cable winding mechanism further includes a second wheel and a third wheel, the second wheel being rotatably connected to a slide and the third wheel being rotatably connected to a base; when the slide is in the first position, the third wheel is located on the side of the slide facing the second connecting segment; the first connecting segment is sequentially wound around the first wheel, the third wheel, and the second wheel, wherein the first connecting segment is wound around the side of the third wheel facing the second connecting segment, and the first connecting segment is wound around the side of the second wheel away from the second connecting segment; during the process of the slide sliding relative to the base from the first position to the second position, the slide drives the cable to move towards the second position through the first wheel and the second wheel, thereby shortening the length of the second connecting segment.

[0008] In some embodiments, a first end of the cable near the first connecting segment is fixed to a base, and the cable further includes a third connecting segment disposed near the second end of the cable. The first connecting segment and the third connecting segment are connected by a second connecting segment. The third connecting segment is sequentially wound around the second rotating wheel, the third rotating wheel and the first rotating wheel, wherein the third connecting segment is wound around the side of the third rotating wheel facing the second connecting segment, and the third connecting segment is wound around the side of the second rotating wheel away from the second connecting segment.

[0009] In some embodiments, the two ends of the first connecting segment are respectively connected to the two ends of the second connecting segment to form a loop.

[0010] In some embodiments, the cable retraction mechanism further includes a first limiting structure and a second limiting structure. The first limiting structure is connected to the base, and the second limiting structure is connected to the slide. The second limiting structure cooperates with the first limiting structure to limit the slide from moving relative to the base toward the first position.

[0011] In some embodiments, the first limiting structure is a strip-shaped toothed structure, and the second limiting structure includes a pawl connected to the slide. The pawl abuts against the teeth of the strip-shaped toothed structure to limit the slide from moving relative to the base toward the first position.

[0012] In some embodiments, the second limiting structure further includes an elastic arm connected between the pawl and the slide, so that the pawl elastically abuts against the ratchet teeth of the strip-shaped tooth structure.

[0013] In some embodiments, the cable retraction mechanism further includes a movable member that cooperates with a second limiting structure; rotating or moving the movable member releases the restriction between the first and second limiting structures, allowing the slide to move from the second position toward the first position.

[0014] In some embodiments, the movable member is rotatably connected to the slide, and the movable member has a protrusion; the protrusion and the second limiting structure are disposed opposite to each other along the rotation direction of the movable member; rotating the movable member to drive the protrusion to rotate, so that the protrusion moves by pushing against the second limiting structure and releases the limitation between the first limiting structure and the second limiting structure.

[0015] In some embodiments, the cable retraction mechanism further includes a knob connected to one end of a movable member; rotating the knob to rotate the movable member to release the restriction between the first limiting structure and the second limiting structure; pushing the knob toward the first position to move the slide toward the first position via the movable member, thereby extending the length of the second connecting segment; and pushing the knob toward the second position to move the slide toward the second position via the movable member, thereby shortening the length of the second connecting segment.

[0016] Secondly, embodiments of the present invention provide a wearable electronic device.

[0017] This invention provides a wearable electronic device including any of the cable retraction mechanisms provided in this invention.

[0018] In some embodiments, the wearable electronic device further includes: a strap, a first connector, a second connector, and a device body; the first connector is connected to a base, the second connector is connected to the strap, and the strap extends from the second connector toward the first connector; cables are respectively passed through the strap and the second connector; the first connector is connected to a first connection portion of the device body, and the second connector is connected to a second connection portion of the device body.

[0019] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: In an embodiment of the invention, the first connecting segment of the cable is wound around the first rotating wheel. Thus, for example, during the movement of the drive slide away from the second connecting segment of the cable, the first rotating wheel can "pull" the cable away from the second connecting segment, thereby bringing the second connecting segment closer to the base. This shortens the length of the second connecting segment extending beyond the base. Alternatively, during the movement of the drive slide towards the second connecting segment of the cable, the first rotating wheel can "release" the cable, increasing the length of the second connecting segment extending beyond the base.

[0020] In this way, for cable ties equipped with a cable retraction mechanism, the length of the second connecting section of the cable extending beyond the base can be easily adjusted by sliding the drive slide between a first and a second position relative to the base, thereby effectively adjusting the length of the cable tie. This avoids the problem in related technologies where Velcro easily gets stuck with hair, causing inconvenience for the user in adjusting the length of the cable tie.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the inventor in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0028] Furthermore, the invention should be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0029] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] This invention provides a cable retraction mechanism. (See reference...) Figures 1 to 10 The cable winding and unwinding mechanism 100 provided in this embodiment of the invention includes: a base 110, a slide 120, a first rotating wheel 131, and a cable 140.

[0031] The slide 120 is slidably connected to the base 110, and the first rotating wheel 131 is rotatably connected to the slide 120. The cable 140 includes a first connecting segment 141 and a second connecting segment 142 connected to each other. The first connecting segment 141 is wound around the side of the first rotating wheel 131 opposite to the second connecting segment 142, and the first connecting segment 141 is connected to the slide 120 through the first rotating wheel 131. The second connecting segment 142 is the portion of the cable 140 that extends beyond the base 110. The slide 120 slides relative to the base 110 between a first position 100a and a second position 100b, adjusting the length of the second connecting segment 142 of the cable 140 extending beyond the base 110.

[0032] In this manner, in an embodiment of the invention, the first connecting segment 141 of the cable 140 is wound around the first rotating wheel 131. Thus, for example, during the movement of the drive slide 120 away from the second connecting segment 142 of the cable 140, the first rotating wheel 131 can "pull" the cable 140 away from the second connecting segment 142, thereby bringing the second connecting segment 142 closer to the base 110. This shortens the length of the second connecting segment 142 of the cable 140 extending beyond the base 110. Alternatively, during the movement of the drive slide 120 towards the second connecting segment 142 of the cable 140, the first rotating wheel 131 can "release" the cable 140, increasing the length of the second connecting segment 142 of the cable 140 extending beyond the base 110.

[0033] In this way, for the cable tie equipped with the cable retraction mechanism 100, the length of the second connecting section 142 of the cable 140 extending outside the base 110 can be adjusted more easily by sliding the drive slide 120 relative to the base 110 between the first position 100a and the second position 100b, thereby effectively adjusting the length of the cable tie 10. This avoids the problem in related technologies where Velcro easily gets stuck with hair, causing inconvenience for the user in adjusting the length of the cable tie.

[0034] refer to Figures 3 to 5 In some embodiments, the base 110 is provided with a slide rail 111, and the slide block 120 is provided with a slide groove 122. The slide groove 122 is slidably connected to the slide rail 111 to provide sliding guidance during the sliding of the slide block 120 relative to the base 110. It is understood that the base 110 and the slide block 120 can be slidably connected using other sliding guidance mechanisms in related technologies to provide sliding guidance during the sliding of the slide block 120 relative to the base 110. Since it is not difficult to achieve the slidable connection between the base 110 and the slide block 120, the specific scheme for achieving the slidable connection between the base 110 and the slide block 120 will not be described in detail here.

[0035] refer to Figures 3 to 6In some embodiments, both ends of the cable 140 are fixed to the base 110. The first position 100a is close to the second connecting segment 142, and the second position 100b is away from the second connecting segment 142. During the sliding of the slide 120 relative to the base 110 from the first position 100a towards the second position 100b, the slide 120, through the first rotating wheel 131, drives the cable 140 towards the second position 100b, thereby shortening the length of the second connecting segment 142.

[0036] by Figure 3 Taking the shown orientation as an example, the second connecting segment 142 extends from the right side of the base 110. The first position 100a is located to the right of the second position 100b. During the sliding process of the slide 120 relative to the base 110 from right to left, the slide 120 drives the cable 140 to move to the left through the first rotating wheel 131, thereby shortening the length of the second connecting segment 142 of the cable 140 extending outside the base 110. Thus, in the embodiment of the present invention, the first rotating wheel 131 acts like a movable pulley, and by driving the first rotating wheel 131 to move a small displacement, the cable 140 can have a large displacement, thereby amplifying the displacement and improving the cable winding and unwinding effect of the cable winding and unwinding mechanism 100.

[0037] In some embodiments, when the slide 120 is in the first position 100a, one end of the cable 140 near the first rotating wheel 131 is fixed between the slide 120 and the second connecting segment 142. This allows a portion of the first connecting segment 141 to be located on the side of the first rotating wheel 131 away from the second connecting segment 142. Therefore, when the first rotating wheel 131 is driven to move in the direction away from the second connecting segment 142, the second connecting segment 142 can be "pulled" back to the area where the base 110 is located. This effectively adjusts the length of the second connecting segment 142 of the cable 140 extending beyond the base 110.

[0038] refer to Figures 3 to 6 In some embodiments, the cable retraction mechanism 100 further includes a second wheel 132 and a third wheel 133. The second wheel 132 is rotatably connected to the slide 120, and the third wheel 133 is rotatably connected to the base 110.

[0039] With the slide 120 in the first position 100a, the third roller 133 is located on the side of the slide 120 facing the second connecting section 142. The first connecting section 141 is sequentially wound around the first roller 131, the third roller 133, and the second roller 132, wherein the first connecting section 141 is wound around the side of the third roller 133 facing the second connecting section 142, and the first connecting section 141 is wound around the side of the second roller 132 away from the second connecting section 142.

[0040] During the process of sliding the slide block 120 relative to the base 110 from the first position 100a to the second position 100b, the slide block 120 drives the cable 140 to move toward the second position 100b through the first rotating wheel 131 and the second rotating wheel 132, thereby shortening the length of the second connecting section 142.

[0041] by Figure 3 Taking the shown orientation as an example, the second position 100b is located to the left of the first position 100a. During the sliding of the slide 120 from right to left, the first wheel 131 and the second wheel 132 move with the slide 120 from right to left, thereby driving the cable 140 to move from right to left, which can shorten the length of the second connecting section 142.

[0042] It should be noted that by employing the arrangement of both the first rotating wheel 131 and the second rotating wheel 132 mounted on the slide 120, both the first rotating wheel 131 and the second rotating wheel 132 function similarly to movable pulleys, thereby amplifying the travel distance of the cable winding mechanism 100. For example, if the slide 120, the first rotating wheel 131, and the second rotating wheel 132 move 10 mm to the left, the first connecting segment 141 of the cable 140 located in the area of ​​the base 110 will lengthen by 40 mm, thereby shortening the second connecting segment 142 by 40 mm.

[0043] refer to Figure 3 In some embodiments, the first end 140a of the cable 140 near the first connecting segment 141 is fixed to the base 110. The cable 140 also includes a third connecting segment 143 disposed near the second end 140b of the cable, and the first connecting segment 141 and the third connecting segment 143 are connected by a second connecting segment 142. The third connecting segment 143 is sequentially wound around the second rotating wheel 132, the third rotating wheel 133 and the first rotating wheel 131, wherein the third connecting segment 143 is wound around the side of the third rotating wheel 133 facing the second connecting segment 142, and the third connecting segment 143 is wound around the side of the second rotating wheel 132 away from the second connecting segment 142.

[0044] In this way, Figure 3 Taking the illustrated orientation as an example, by having the first connecting segment 141 and the third connecting segment 143 respectively wound around the second rotating wheel 132, the third rotating wheel 133, and the first rotating wheel 131, the upper and lower parts of the second connecting segment 142 can move synchronously to the left during the sliding of the drive slide 120, the first rotating wheel 131, and the second rotating wheel 132 from right to left. This allows the upper and lower parts of the second connecting segment 142 to shorten synchronously. Therefore, by adopting the solution provided in this embodiment of the invention, the extension and retraction of the second connecting segment 142 can be performed effectively.

[0045] refer to Figure 3When the slide block 120 is in the first position 100a, both the first end 140a and the second end 140b of the cable 140 are fixed between the slide block 120 and the second connecting segment 142. This allows the first connecting segment 141 of the cable 140 to be sequentially wound around the left side of the first rotating wheel 131, the right side of the third rotating wheel 133, and the left side of the second rotating wheel 132; and the third connecting segment 143 of the cable 140 to be sequentially wound around the left side of the second rotating wheel 132, the right side of the third rotating wheel 133, and the left side of the first rotating wheel 131. Therefore, during the process of driving the slide block 120, the first rotating wheel 131, and the second rotating wheel 132 to slide to the left, the upper and lower parts of the second connecting segment 142 move synchronously to the left, allowing the upper and lower parts of the second connecting segment 142 to shorten synchronously. Therefore, the solution provided by this embodiment of the invention can effectively retract and extend the second connecting segment 142.

[0046] For example, the first end 140a of the cable 140 is provided with a first loop, and the second end 140b of the cable 140 is provided with a second loop. The base 110 is provided with a first protrusion and a second protrusion. The first loop is sleeved on the first protrusion, and the second loop is sleeved on the second protrusion. In this way, the first end 140a and the second end 140b of the cable 140 can be connected to the base 110 respectively.

[0047] Of course, in other embodiments, other methods can also be used to connect the first end 140a and the second end 140b of the cable 140 to the base 110 respectively. For example, the first end 140a and the second end 140b of the cable 140 can be connected to the base 110 respectively by means of adhesive bonding, threaded connection, etc., which will not be listed here.

[0048] refer to Figure 7 In some embodiments, the two ends of the first connecting segment 141 are respectively connected to the two ends of the second connecting segment 142, so that the cable 140 is in a loop. In other words, the cable 140 is a complete loop structure. In other words, the cable 140 has no breaks. In this way, there is no need to configure connection points on the base 110 for fixing the two ends of the cable 140, thus simplifying the construction of the base 110.

[0049] refer to Figures 2 to 6In some embodiments, the cable retraction mechanism 100 further includes a first limiting structure 151 and a second limiting structure 152. The first limiting structure 151 is connected to the base 110, and the second limiting structure 152 is connected to the slide 120. The second limiting structure 152 cooperates with the first limiting structure 151 to limit the movement of the slide 120 relative to the base 110 toward the first position 100a. In this way, the second limiting structure 152 and the first limiting structure 151 form a one-way sliding limiter, so that the cable retraction mechanism 100 can more easily retract the cable 140 and the cable 140 is less likely to be accidentally released.

[0050] In some embodiments, the first limiting structure 151 is a strip-shaped toothed structure, and the second limiting structure 152 includes a pawl 1521. The pawl 1521 is connected to the slide 120, and the pawl 1521 abuts against the ratchet teeth 1511 of the strip-shaped toothed structure to limit the movement of the slide 120 relative to the base 110 toward the first position 100a.

[0051] For example, the side of the ratchet 1511 facing away from the second connecting segment 142 is the first stop surface, and the side of the pawl 1521 opposite to the first stop surface is the second stop surface. The second stop surface of the pawl 1521 is used to abut against the first stop surface, so that when the pawl 1521 and the ratchet 1511 are in the connected state, the pawl 1521 will not move towards the second connecting segment 142 on its own, thereby preventing the slide 120 connected to the pawl from moving towards the first position 100a on its own. The side of the ratchet 1511 facing the second connecting segment 142 from the first stop surface is provided with a first guide surface, and the side of the pawl 1521 opposite to the first stop surface is the second guide surface. During the process of driving the slide 120 to move towards the second position 100b, the first guide surface and the second guide surface cooperate, causing the pawl 1521 to separate from the currently engaged ratchet 1511. This allows the pawl 1521 to move relative to the current ratchet 1511 and engage with the next ratchet 1511.

[0052] In some embodiments, the second limiting structure 152 further includes an elastic arm 1522. The elastic arm 1522 is connected between the pawl 1521 and the slide block 120, allowing the pawl 1521 to elastically abut against the ratchet teeth 1511 of the strip-shaped tooth structure. Thus, by providing the elastic arm 1522 between the pawl 1521 and the slide block 120, the pawl 1521 can move relative to the ratchet teeth 1511 in a direction opposite to the depth direction from the ratchet teeth 1511.

[0053] It should be noted that, with Figure 4Taking the illustrated orientation as an example, during the sliding of the slide block 120 from right to left, the first guide surface on the right side of the ratchet 1511 acts as a cam, thereby pushing up the pawl 1521 via the first guide surface on the left side of the pawl 1521. This causes the elastic arm 1522 to bend upwards on the side closest to the pawl 1521, thus separating the pawl 1521 from the previously engaged ratchet 1511. In this way, the slide block 120 can slide from right to left under drive. When the driving force applied to the slide block 120 is removed, the pawl 1521 engages with the ratchet 1511, and the first stop surface on the left side of the ratchet 1511 abuts against the second stop surface on the right side of the pawl 1521, thereby preventing the slide block 120 from sliding to the right accidentally.

[0054] It should be noted that in other embodiments, the cable retraction mechanism 100 may not be provided with the first limiting structure 151 and the second limiting structure 152. For example, there is a suitable amount of friction between the slide 120 and the base 110, so that the slide 120 is not easy to slide to the right due to accident by using the friction.

[0055] In other embodiments, the slide 120 is provided with a releasable locking structure, so that when the locking structure is in the unlocked state, the slide 120 can be easily driven to move relative to the base 110; when the locking structure is in the locked state, the slide 120 is fixed relative to the base 110 by the locking structure, thereby preventing the slide 120 from sliding to the right accidentally. Exemplarily, the locking structure includes a screw threadedly connected to the slide 120. When the screw is screwed in, the screw abuts against the base 110, thereby preventing the slide 120 from sliding to the right accidentally. When the screw is loosened, the screw separates from the base 110, thereby allowing the slide 120 to move relative to the base 110 when driven.

[0056] In other embodiments, the first limiting structure 151 and the second limiting structure 152 may also have other configurations. For example, the first limiting structure 151 and the second limiting structure 152 may be configured using a ratchet mechanism from related technologies. This embodiment of the invention does not limit the specific construction of the first limiting structure 151 and the second limiting structure 152; it only requires that the second limiting structure 152 cooperates with the first limiting structure 151 to restrict the slide block 120 from sliding relative to the base 110 in the direction toward the first position 100a.

[0057] refer to Figure 4 and Figure 5In some embodiments, the cable retraction mechanism 100 further includes a movable member 160. The movable member 160 cooperates with the second limiting structure 152. Exemplarily, the movable member 160 and the second limiting structure 152 are connected in a driving engagement. Rotating or moving the movable member 160 releases the restriction between the first limiting structure 151 and the second limiting structure 152, allowing the slide 120 to move from the second position 100b toward the first position 100a. Thus, when it is necessary to release the cable 140, the first limiting structure 151 and the second limiting structure 152 can be separated by driving the movable member 160 to release the restriction between them.

[0058] In some embodiments, the movable member 160 is rotatably connected to the slide 120, and the movable member 160 is provided with a protrusion 161. The protrusion 161 and the second limiting structure 152 are disposed opposite to each other along the rotation direction of the movable member 160. Rotating the movable member 160 causes the protrusion 161 to rotate, so that the protrusion 161 moves by pushing against the second limiting structure 152, thereby releasing the restriction between the first limiting structure 151 and the second limiting structure 152. In this way, when it is necessary to release the cable 140, the first limiting structure 151 and the second limiting structure 152 can be released by rotating the movable member 160.

[0059] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the cable retraction mechanism 100 further includes a knob 162 connected to one end of the movable member 160. Rotating the knob 162 causes the movable member 160 to rotate, thereby releasing the restriction between the first limiting structure 151 and the second limiting structure 152. Pushing the knob 162 toward the first position 100a causes the slide 120 to move toward the first position 100a via the movable member 160, thereby extending the length of the second connecting segment 142. Pushing the knob 162 toward the second position 100b causes the slide 120 to move toward the second position 100b via the movable member 160, thereby shortening the length of the second connecting segment 142.

[0060] by Figure 2 Taking the indicated directions as an example, combined with Figure 4 and Figure 5 The user can adjust the length of the second connecting segment 142 by manipulating the knob 162, moving the movable part 160 and the slide 120 toward the first position 100a or the second position 100b. In addition, the user can rotate the movable part 160 by manipulating the knob 162, thereby releasing the restriction between the first limiting structure 151 and the second limiting structure 152.

[0061] In some embodiments, when the first limiting structure 151 is a strip-shaped toothed structure, the second limiting structure 152 includes a pawl 1521 and an elastic arm 1522, and the cable retraction mechanism 100 includes a movable member 160 and a knob 162, the protrusion 161 of the movable member 160 and the elastic arm 1522 are arranged opposite to each other along the rotation direction of the movable member 160. Therefore, when it is necessary to release the cable 140, the protrusion 161 can be rotated to deform the elastic arm 1522, thereby separating the pawl 1521 from the ratchet 1511 and releasing the ratchet 1511 from locking the pawl 1521. Furthermore, the length of the second connecting segment 142 can be increased by driving the knob 162 to move towards the first position 100a.

[0062] It should be noted that in other embodiments, the pawl 1521 and the slide 120 may have other structures to allow for elastic engagement between them. For example, the pawl 1521 may be slidably connected to the slide 120, and a spring may be provided between the pawl 1521 and the slide 120. Furthermore, when it is necessary to release the cable 140, the pawl 1521 may be driven to slide relative to the slide 120 by manipulating the movable part 160, thereby separating the pawl 1521 from the ratchet 1511 and releasing the lock of the ratchet 1511 on the pawl 1521.

[0063] refer to Figures 2 to 5 In some embodiments, the cable retraction mechanism 100 further includes a cover 121. The cover 121 is connected to the slide 120 and is located on the side of the slide 120 opposite to the base 110. In some embodiments, the first roller 131 and the second roller 132 are sandwiched between the slide 120 and the cover 121.

[0064] It should be noted that, although Figure 1 As shown, when cable 140 extends a certain distance from the area where slide 120 is located and then extends back to the area where slide 120 is located, it can be understood that in other embodiments, cable 140 may also extend a certain distance from the area where slide 120 is located and then not extend back to the area where slide 120 is located. In this way, the second connecting segment 142 of cable 140 can also be moved relative to base 110 by driving slide 120 to achieve the extension and retraction of cable 140.

[0065] It should also be noted that, although Figure 4 The diagram shows a configuration where both ends of cable 140 are connected to base 110. It is understood that, with reference to... Figure 7 In other embodiments, the cable may be looped. In other words, the cable is constructed as a single loop.

[0066] In some embodiments, the cable 140 may be made of a chain. Alternatively, the cable 140 may be made of silk. For example, the material of the silk may include at least one of plastic and metal. Alternatively, the cable 140 may include a metal wire core and a sheath, with the protective sleeve disposed outside the metal wire core. The embodiments of the present invention do not limit the specific material of the cable 140, as long as it can be wound around each of the rotating wheels and can move with the rotating wheels during their movement.

[0067] This invention provides a binding strap. (See reference...) Figure 8 and Figure 9 The strap 10 provided in this embodiment of the invention includes: a strap body 200, a first connecting seat 300, a second connecting seat 400, and any of the cable retraction mechanisms 100 provided in this embodiment of the invention. The first connecting seat 300 is connected to the base 110, and the second connecting seat 400 is connected to the strap body 200. The strap body 200 extends from the second connecting seat 400 toward the first connecting seat 300. The cable 140 is respectively passed through the strap body 200 and the second connecting seat 400.

[0068] For example, the belt body 200 is provided with a strip-shaped hole 210. (See reference) Figure 5 , Figure 8 and Figure 9 In some embodiments, a portion of the movable member 160 passes through the strip hole 210.

[0069] This invention provides a wearable electronic device. (See reference...) Figures 1 to 10 The wearable electronic device 1 provided in this embodiment of the invention includes: any of the cable retraction mechanisms 100 provided in this embodiment of the invention.

[0070] In some embodiments, the wearable electronic device 1 further includes a strap 200, a first connector 300, a second connector 400, and a device body 20. The first connector 300 is connected to a base 110, and the second connector 400 is connected to the strap 200, with the strap 200 extending from the second connector 400 toward the first connector 300. Cables 140 are respectively threaded through the strap 200 and the second connector 400. The first connector 300 is connected to a first connecting portion 21 of the device body 20, and the second connector 400 is connected to a second connecting portion 22 of the device body 20.

[0071] For example, when the cable 140 is tightened, the distance between the first connector 300 and the second connector 400 decreases. When the cable 140 is released, the distance between the first connector 300 and the second connector 400 increases. Therefore, by reasonably adjusting the distance between the first connector 300 and the second connector 400, the belt 200 can be properly fitted around the user's head.

[0072] For example, wearable electronic device 1 is a head-mounted display device. Alternatively, wearable electronic device 1 is glasses. For example, head-mounted display devices include extended reality (XR) devices, augmented reality (AR) devices, virtual reality (VR) devices, and mixed reality (MR) devices.

[0073] It should be noted that when the cable retraction mechanism 100, the strap body 200, the first connecting seat 300, and the second connecting seat 400 are combined to form the strap 10, the wearable electronic device 1 may include the strap 10. Furthermore, the wearable electronic device 1 also includes a device body 20. The first connecting seat 300 is connected to the first connecting portion 21 of the device body 20, and the second connecting seat 400 is connected to the second connecting portion 22 of the device body 20.

[0074] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0075] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the embodiments of the invention, the scope of which is defined by the appended claims and their equivalents.
