Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and particularly to an adjustable wearing mechanism. This invention also relates to a head-mounted device. Background Technology

[0002] With the development of virtual reality and augmented reality technologies, more and more head-mounted devices have been widely used, such as VR (Virtual Reality) headsets and AR (Augmented Reality) headsets. VR technology is a computer simulation system that can create and experience virtual worlds. It uses computer-generated simulated environments to immerse users in those environments. AR technology is a technology that cleverly integrates virtual information with the real world. It widely uses multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, sensing, and other technologies to simulate computer-generated virtual information and then apply it to the real world.

[0003] Currently, to improve wearing comfort, all head-mounted devices are equipped with a wearing mechanism, primarily consisting of straps. These straps secure the device to the user's head, typically wrapping around the sides and back of the head. Considering the varying head sizes of different users, the tightness of the straps is usually adjustable to accommodate different body types and individual head circumferences.

[0004] In existing technology, headbands for head-mounted devices on the market are mainly divided into two types: the first type is made of rigid materials, such as rigid plastic straps or thin metal strips; the second type is made of soft materials, such as woven straps, cloth straps, or rubber straps. Although both rigid and soft material straps have a certain degree of elasticity, the former has weaker elasticity, stronger plastic support, and greater rigidity. Its tightness adjustment mainly relies on scaling, which can easily cause discomfort to the user during wear, resulting in poor wearing comfort. The latter, on the other hand, has stronger elasticity and better wearing comfort, but its tightness adjustment relies solely on the elastic deformation of the material itself, resulting in a smaller adjustment range and poor adaptability.

[0005] Therefore, how to balance the range of adjustment and wearing comfort while achieving adjustable strap tightness, improve adaptability to different users, and optimize user experience is a technical problem faced by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable wearing mechanism that, while allowing for adjustment of the strap tightness, also considers the range of adjustment and wearing comfort, improving adaptability to different users and optimizing the user experience. Another purpose of this invention is to provide a head-mounted device.

[0007] To solve the above-mentioned technical problems, the present invention provides an adjustable wearing mechanism, including a first strap and a second strap;

[0008] One end of the first band is retractably connected to the main body of the head-mounted device;

[0009] One end of the second belt is connected to the other end of the first belt, and the other end of the second belt is connected to the main body of the device. The second belt is used to tighten the wearing part, and the second belt is made of soft material.

[0010] In some specific embodiments, a storage box is also included, which is disposed on the side wall of the main body of the device. One end of the storage box is open, and one end of the first strap is retractably inserted into the opening of the storage box.

[0011] In some specific embodiments, it also includes an adjustment knob rotatably inserted into the storage box, and a transmission mechanism disposed within the storage box. The input end of the transmission mechanism is poweredly connected to the adjustment knob, the output end of the transmission mechanism is connected to one end of the first belt, and one end of the first belt is slidably disposed within the storage box.

[0012] In some specific embodiments, the transmission mechanism includes a gear and a rack that mesh with each other, the gear being poweredly connected to the adjustment knob, the rack being disposed at one end of the first belt and extending along the sliding direction of the first belt.

[0013] In some specific embodiments, one end of the first belt body is provided with a long sliding hole extending along its sliding direction, and the rack is disposed on the inner wall of the long sliding hole.

[0014] In some specific embodiments, a positioning bearing protruding from the inner wall of the storage box is also included, and the inner edge of the gear is sleeved on the positioning bearing.

[0015] In some specific embodiments, a winch and a traction rope are also included. The winch is poweredly connected to the adjustment knob. One end of the traction rope is connected to the winch, and the other end passes through and is connected to the second belt body to drive the second belt body to produce elastic deformation.

[0016] In some specific embodiments, a drive disk is also included;

[0017] The inner edge of the winch is provided with toothed grooves;

[0018] The drive disc is sleeved inside the winch, and the end face of the drive disc is poweredly connected to the adjustment knob. The outer edge of the drive disc is provided with protruding teeth for engaging with the tooth groove.

[0019] In some specific embodiments, a drive claw is also included;

[0020] A mating groove is provided on the end face of the drive disk;

[0021] One end of the driving claw is poweredly connected to the adjustment knob, and the other end of the driving claw is provided with a connecting plate for engaging with the connecting groove.

[0022] The present invention also provides a head-mounted device, including a device body and an adjustable wearing mechanism disposed on the device body, wherein the adjustable wearing mechanism is specifically the adjustable wearing mechanism described in any of the above claims.

[0023] The adjustable wearing mechanism provided by this invention mainly includes a first strap and a second strap. One end of the first strap is connected to the main body of the head-mounted device, forming a movable connection. It can extend and retract relative to the main body in a preset direction to adjust the tightness of the strap. One end of the second strap is connected to the other end of the first strap, and the other end of the second strap is connected to the main body, making the first and second straps a single unit (i.e., a strap). This forms a semi-enclosed structure on the main body or together with the main body to form a closed space for the user to wear (on the head or other parts of the body). Importantly, the first strap does not directly contact the user's wearing area; only the second strap directly contacts the user's wearing area to tighten the wearing area and fix the main body of the device on the user's wearing area. Furthermore, the second strap is made of a soft material, which is not only elastic and capable of elastic deformation, but also soft in texture, providing good wearing comfort and avoiding hard contact with the skin when tightening the user's wearing parts.

[0024] Thus, the adjustable wearing mechanism provided by this invention only requires operation of the first strap body when the tightness of the fit needs to be adjusted. This allows the first strap body to extend and retract relative to the main body of the device, thereby increasing or decreasing the extension length of the first strap body. This, in turn, allows adjustment of the size of the wearing space enclosed by the first strap body, the second strap body, and the main body of the device. The size of the wearing space corresponds to the tightness of the fit. Furthermore, the extension length and the size of the wearing space can be adjusted to a considerable extent through the extension and retraction of the first strap body. At the same time, when the user wears the device, the second strap body mainly tightens the user's wearing area to achieve stable wear, and the soft material properties of the second strap body ensure wearing comfort.

[0025] In summary, the adjustable wearing mechanism provided by this invention can achieve adjustment of the strap tightness while taking into account the range of adjustment and wearing comfort, thereby improving adaptability to different users and optimizing the user experience.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please refer to Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a specific embodiment of the present invention. Figure 2 for Figure 1 Top view.

[0049] In one specific embodiment of the present invention, the adjustable wearing mechanism mainly includes a first strap 2 and a second strap 3.

[0050] One end of the first strap 2 is connected to the main body 1 of the head-mounted device and forms a movable connection with the main body 1, and can perform telescopic movement in a preset direction relative to the main body 1 to realize the tightness adjustment of the strap.

[0051] One end of the second strap 3 is connected to the other end of the first strap 2, and the other end of the second strap 3 is connected to the device body 1, so that the first strap 2 and the second strap 3 are connected as a whole (i.e., a strap), forming a semi-enclosed structure on the device body 1 or forming a closed space together with the device body 1 for the user to wear (on the head or other parts). Importantly, the first strap 2 does not directly contact the user's wearing part, only the second strap 3 directly contacts the user's wearing part to tighten the wearing part and fix the device body 1 on the user's wearing part; at the same time, the second strap 3 is made of soft material, which is not only elastic and can produce elastic deformation, but also soft in texture and comfortable to wear, avoiding hard contact with the skin when tightening the user's wearing part.

[0052] like Figure 3 , Figure 4 As shown, Figure 3 This is a schematic diagram of the first belt 2 in its extended state. Figure 4 This is a schematic diagram of the first belt 2 in its retracted state.

[0053] Thus, the adjustable wearing mechanism provided in this embodiment only requires operation of the first strap 2 when the tightness of the fit needs to be adjusted. This allows the first strap 2 to extend and retract relative to the main body 1 of the device, thereby increasing or decreasing the extension length of the first strap 2. This, in turn, adjusts the size of the wearing space enclosed by the first strap 2, the second strap 3, and the main body 1 of the device. The size of the wearing space corresponds to the tightness of the fit. Furthermore, the extension and retraction of the first strap 2 allows for a significant adjustment of its extension length and the size of the wearing space. Simultaneously, when the user wears the device, the second strap 3 secures the user's wearing area for stable wear, while the soft material of the second strap 3 ensures wearing comfort.

[0054] In summary, the adjustable wearing mechanism provided in this embodiment can achieve adjustment of the strap tightness while taking into account the range of adjustment and wearing comfort, thereby improving adaptability to different users and optimizing the user experience.

[0055] like Figure 5 , Figure 6 As shown, Figure 5 This is an exploded view of the internal structure of storage box 4. Figure 6 for Figure 5 Another perspective illustration.

[0056] To facilitate the telescopic movement of the first strap 2 on the device body 1, a storage box 4 is added in this embodiment. Specifically, the storage box 4 is located on the side wall of the device body 1, such as the left or right side wall, and one end of the storage box 4 is open, mainly for the passage of the first strap 2. Simultaneously, the end of the first strap 2 (the non-connecting end; the end connected to the second strap 3 is the connecting end) is inserted into the opening of the storage box 4 and can telescopically move within the storage box 4 to adjust the extension length. Generally, the length of the storage box 4 is equal to or slightly larger than the length of the first strap 2, allowing the first strap 2 to be completely inserted into the storage box 4 for concealed storage, while also achieving the minimum extension length and the tightest fit.

[0057] In one specific embodiment of the storage box 4, the storage box 4 mainly includes an inner shell 41 and an outer shell 42. The inner shell 41 is attached to the outer wall of the device body 1, for example, by adhesive bonding or threaded connection. The outer shell 42 and the inner shell 41 interlock, forming a sealed cavity to house the first strap 2. Of course, the storage box 4 can also be a one-piece structure.

[0058] like Figure 7 , Figure 8 As shown, Figure 7 for Figure 5 The structure shown is a sectional view along the vertical direction. Figure 8 for Figure 6 The structure shown is a cross-sectional view along the horizontal direction.

[0059] To facilitate user adjustment of the telescopic movement of the first belt 2, an adjustment knob 5 and a transmission mechanism 6 are added in this embodiment. The adjustment knob 5 is mounted on the storage box 4, typically inserted into the outer shell 42 of the storage box 4, and rotatably connected to the outer shell 42. It has rotational freedom and can rotate on the outer shell 42, primarily for user adjustment of tightness. The transmission mechanism 6 is located inside the storage box 4, with its input end connected to the adjustment knob 5 and its output end connected to the non-connected end of the first belt 2. It primarily transmits the power from the adjustment knob 5 to the first belt 2, driving it to telescopically move. Specifically, the non-connected end of the first belt 2 is slidably connected to the opening of the storage box 4, and the transmission mechanism 6 converts the rotational movement of the adjustment knob 5 into linear motion and outputs it to the first belt 2, driving it to slide linearly within the storage box 4, thus achieving the telescopic movement effect through linear reciprocating sliding.

[0060] With this design, users can easily extend and retract the first strap 2 by simply turning the adjustment knob 5 clockwise or counterclockwise, thereby adjusting the tightness of the fit. Furthermore, since the storage box 4 is located on the side wall of the main body 1, the adjustment knob 5 is positioned to the side of the main body 1. Compared to the prior art where the adjustment knob 5 is located on the strap or at the rear of the main body 1, the adjustable wearing mechanism provided in this embodiment can meet the user's needs for a lying posture and avoid causing discomfort or pressure on the back of the user's head.

[0061] Furthermore, in order to improve the stability of the sliding movement of the first belt 2 within the storage box 4, in this embodiment, the inner shell 41 of the storage box 4 is specifically a U-shaped groove structure to form a guide groove for the first belt 2, thereby enabling the first belt 2 to slide within the guide groove and providing a guiding effect for the sliding movement of the first belt 2.

[0062] like Figure 9 , Figure 10 As shown, Figure 9 for Figure 7 Assembly drawing of the structure shown. Figure 10 for Figure 8 Assembly diagram of the structure shown.

[0063] In one specific embodiment of the transmission mechanism 6, the transmission mechanism 6 mainly includes a gear 61 and a rack 62. The gear 61 is powered to the adjusting knob 5, for example, by connecting its end face to the inner end face of the adjusting knob 5, enabling synchronous rotation with the adjusting knob 5. The rack 62 is located on the non-connecting end of the first belt 2, primarily for meshing with the gear 61, and specifically extends along the sliding direction of the first belt 2. With this configuration, when the adjusting knob 5 rotates, the gear 61 rotates synchronously with it, and through the meshing of the gear 61 and rack 62, the rotational motion is converted into linear motion, driving the rack 62 to move linearly, thereby causing the first belt 2 to slide linearly within the storage box 4.

[0064] It should be noted that the transmission mechanism 6 is not limited to the gear 61 and rack 62 mentioned above. Other mechanisms that can convert rotary motion into linear motion, such as crank-slider mechanisms, can also be used.

[0065] Furthermore, to facilitate the installation of the rack 62 on the first belt body 2, in this embodiment, an elongated sliding hole 21 is provided on the non-connecting end of the first belt body 2. Specifically, the elongated sliding hole 21 extends along the length direction of the first belt body 2, that is, along the sliding direction of the first belt body 2, and the rack 62 is specifically disposed on the inner wall of the elongated sliding hole 21, for example, on the inner top wall or inner bottom wall of the elongated sliding hole 21. With this arrangement, the gear 61 is completely embedded in the elongated sliding hole 21 and meshes with the rack 62 within the elongated sliding hole 21, realizing the built-in design of the rack 62, which can reduce the structural size.

[0066] Of course, the rack 62 does not have to be built-in; an external design is also feasible, such as fixing the rack 62 to the outer side wall of the first belt body 2.

[0067] To improve the stability of the meshing transmission between gear 61 and rack 62, a positioning bearing 7 is added in this embodiment. Specifically, the positioning bearing 7 protrudes from the inner wall of the inner shell 41 of the storage box 4 and extends towards the outer shell 42 by a predetermined length (or height). Correspondingly, the central region of gear 61 is hollow, and the inner edge of gear 61 is sleeved on the positioning bearing 7, maintaining its rotational freedom. Thus, the positioning bearing 7 supports gear 61, ensuring the stability and smoothness of gear 61's rotational movement, while also fixing the position of gear 61.

[0068] like Figure 11 As shown, Figure 11 An exploded view of the power transmission chain for adjusting knob 5.

[0069] In another specific embodiment provided by the present invention, in order to further expand the adjustment range of the wearing tightness, the adjustable wearing mechanism includes, in addition to the first strap body 2, the second strap body 3, the storage box 4, the adjustment knob 5 and the transmission mechanism 6, a winch 8 and a traction rope 9.

[0070] The winch 8 is housed within the storage box 4 and is poweredly connected to the adjustment knob 5, enabling synchronous rotation. One end of the traction rope 9 is connected to the winch 8, while the other end passes through the second belt body 3 and is fixedly connected to it. Generally, the other end of the traction rope 9 enters the second belt body 3 from the end connected to the first belt body 2 and continues along the extension direction of the second belt body 3 to the other end of the second belt body 3 (i.e., the end connected to the equipment body 1), thus achieving the connection of the entire second belt body 3. Because the second belt 3 is elastic and capable of elastic deformation, when the winch 8 rotates, it gradually winds around one end of the traction rope 9. This creates a traction force on the entire second belt 3 via the traction rope 9. This traction force forces the second belt 3 to elastically contract towards the traction rope 9, thus shortening its length. This effectively reduces the total length of the overall strap formed by the connection between the first belt 2 and the second belt 3, ultimately reducing the wearing space enclosed by the first belt 2, the second belt 3, and the main body of the equipment 1, resulting in a tighter fit. Conversely, when the winch 8 rotates in the opposite direction, the winding portion at one end of the traction rope 9 gradually loosens. Under the elastic effect, the second belt 3 gradually recovers its deformation, and the tightness gradually decreases.

[0071] Generally, multiple traction ropes 9 can be set at the same time, and are respectively threaded through the upper and lower parts of the second belt body 3, so that the second belt body 3 can be pulled by multiple traction ropes 9 at the same time, making the elastic deformation of the second belt body 3 more balanced and stable.

[0072] With this configuration, the adjustable wearing mechanism provided in this embodiment allows for significant adjustment of the wearing tightness when the user rotates the adjustment knob 5. A portion of the rotational power of the adjustment knob 5 is transmitted to the first strap 2 via the transmission mechanism 6, causing the first strap 2 to extend and retract within the storage box 4. Simultaneously, another portion of the rotational power of the adjustment knob 5 is transmitted to the traction rope 9 via the winch 8, causing the second strap 3 to undergo elastic deformation, enabling a small adjustment of the wearing tightness. Furthermore, since the extension and retraction of the first strap 2 and the elastic deformation of the second strap 3 occur synchronously during the rotation of the adjustment knob 5, the adjustments to the wearing tightness are superimposed, expanding the range of adjustable wearing tightness.

[0073] Furthermore, considering that the power of the adjustment knob 5 needs to be transmitted simultaneously to the winch 8 and the transmission mechanism 6 in two separate streams, in this embodiment, to simplify the structure and reduce its size, the winch 8 and the transmission mechanism 6 form an integral structure. For example, when the transmission mechanism 6 uses the aforementioned gear 61 and rack 62, the gear 61 can be fixed to the end face of the winch 8, or the gear 61 and the winch 8 can be integrally formed during manufacturing, thus achieving synchronous movement and coaxial distribution of the two.

[0074] like Figure 12 As shown, Figure 12 for Figure 11 A partial structural diagram.

[0075] To facilitate the power connection between the adjustment knob 5 and the winch 8, a drive disc 10 is added in this embodiment. Correspondingly, the winch 8 in this embodiment is hollow, and the drive disc 10 is specifically fitted inside the winch 8, forming an inner-outer nested installation. Simultaneously, a toothed groove 81 is formed on the inner edge of the winch 8, while a protruding tooth 101 is formed on the outer edge of the drive disc 10. This protruding tooth 101 can engage with the toothed groove 81. Furthermore, the end face of the drive disc 10 is connected to the adjustment knob 5. With this configuration, the rotational power of the adjustment knob 5 is transmitted to the drive disc 10, and the drive disc 10, through the engagement of the protruding tooth 101 with the toothed groove 81 (equivalent to key transmission), continues to transmit the rotational power to the winch 8, causing the winch 8 to rotate, and simultaneously driving the transmission mechanism 6.

[0076] Furthermore, to facilitate the power connection between the adjustment knob 5 and the drive disk 10, a drive claw 11 is added in this embodiment. Correspondingly, a engagement groove 102 is also provided on the end face of the drive disk 10 in this embodiment. At the same time, one end of the drive claw 11 forms a power connection with the adjustment knob 5, while the other end of the drive claw 11 is provided with a engagement plate 111 protruding towards the drive disk 10. This engagement plate 111 can form a snap-fit ​​engagement with the engagement groove 102 on the end face of the drive disk 10 (equivalent to key transmission). With this configuration, the rotational power of the adjustment knob 5 is first transmitted to the drive claw 11, then transmitted to the drive disk 10 through the snap-fit ​​engagement of the engagement plate 111 and the engagement groove 102, and then transmitted to the winch 8 through the snap-fit ​​engagement of the protruding tooth 101 and the tooth groove 81, ultimately driving the winch 8 to rotate and the transmission mechanism 6 to operate.

[0077] Generally, the connecting plate 111 can be in the shape of an arc-shaped sheet, and the connecting groove 102 can be in the shape of an arc-shaped groove. As for the power connection between the adjusting knob 5 and the drive claw 11, a non-circular through hole (such as a rectangular hole, a star-shaped hole, etc.) can be opened on one end face of the drive claw 11. Then, a connecting post or other component with the same shape as the non-circular through hole can be set on the inner end face of the adjusting knob 5. The connecting post or other component can be inserted into the non-circular through hole to realize the power transmission between the two.

[0078] This embodiment also provides a head-mounted device, which mainly includes a device body 1 and an adjustable wearing mechanism disposed on the device body 1. Since the adjustable wearing mechanism adopts all the technical solutions of the above-mentioned adjustable wearing mechanism embodiments, the head-mounted device provided in this embodiment also has all the technical effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0079] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
