[0029] The embodiments of the present application can be applied to various application scenarios such as extended reality (XR), virtual reality (VR), augmented reality (AR), and mixed reality (MR).

[0030] Among them, extended reality (XR) is a concept that includes virtual reality (VR), augmented reality (AR), and mixed reality (MR), which represents an environment where a virtual world is connected to the real world, and a technology that enables users to interact with this environment in real - time.

[0031] An XR device is a terminal for realizing the extended reality effect. An XR device can include devices in the form of glasses, head - mounted displays (HMDs), contact lenses, etc., for realizing visual perception and other forms of perception.

[0032] The XR device may also include a wearable device capable of interacting with the user. The wearable device can be fixed to the user's wrist or upper limb. The wearable device has a wristband, a main control module, and a collection module. The main control module and the collection module are respectively installed on the wristband. The collection module can be used to collect EMG (Electromyography) signals, etc. However, since the sizes of the wrists or upper limbs of users in different age groups are different, how to adapt the wristband in the wearable device to wrists or upper limbs of different sizes has become an urgent problem to be solved in the industry.

[0033] In order to overcome the above problems, this embodiment provides a fixing device and a wearable device. By providing a tightening component and a locking component, the tightening component can wind up the tightening belt until it fits the size of the current user's wrist or upper limb, and the tightening component can be locked by the locking component, so that the tightening belt and the flexible belt of the wearable device can be kept in a state adapted to the user's wrist or upper limb. Thus, the wearable device can be applicable to users in more age groups and is highly convenient to wear.

[0034] The following uses specific embodiments to detail the technical solution of this application and how the technical solution of this application solves the above technical problems. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the drawings.

[0035] The fixing device 1 provided in this embodiment is used for a wearable device. The wearable device may include, but is not limited to: a smart bracelet, a smart wristband, etc.

[0036] Please refer to Figures 1 to 4 , the fixing device 1 provided in this embodiment includes: a flexible belt 11; a tightening belt 12, the tightening belt 12 is threaded through the flexible belt 11, and the length direction of the tightening belt 12 is parallel to the length direction of the flexible belt 11; a mounting shell 13, the mounting shell 13 is connected to the end of the flexible belt 11; a tightening component 14, a part of the tightening component 14 is located in the mounting shell 13, the tightening component 14 is connected to the tightening belt 12, and the tightening component 14 is used for winding up the tightening belt 12; a locking component 15, the locking component 15 is used for locking the tightening component 14 and the mounting shell 13 when the tightening component 14 winds up the tightening belt 12 to a target position.

[0037] The flexible belt 11 and the tightening belt 12 form the wristband of the wearable device. The flexible belt 11 has a mating hole extending along its length direction. The tightening belt 12 is threaded through the mating hole, and at least one end of the tightening belt 12 can extend out of the mating hole. When the tightening belt 12 is in an untightened state, the length of the tightening belt 12 can be greater than the length of the flexible belt 11. The wristband of the wearable device can be adapted to the wrists or upper limbs of different users with different sizes by adjusting the winding situation of the tightening belt 12.

[0038] The end of the tightening belt 12 can be fixedly connected to the winding shaft 141 of the tightening assembly 14. The winding shaft 141 can be located in the mounting shell 13. The mounting shell 13 is a hollow shell generally in a columnar shape. The mounting shell 13 can accommodate at least part of the winding shaft 141, and the mounting shell 13 can also accommodate the tightening belt 12 wound around the winding shaft 141. According to actual needs, the mounting shell 13 can also accommodate other structural components.

[0039] During the wearing process, the winding shaft 141 can rotate under the action of a driving force and wind up the tightening belt 12 to reduce the length of the tightening belt 12, so that the space enclosed by the tightening belt 12 and the flexible belt 11 becomes smaller until the space enclosed by the tightening belt 12 and the flexible belt 11 can fit the current user's wrist or upper limb. If the length of the tightening belt 12 is too small, under the action of a driving force in the opposite direction, the winding shaft 141 can rotate in the reverse direction and release the tightening belt 12.

[0040] Among them, both ends of the tightening belt 12 can be fixed on the winding shaft 141 to quickly wind up or release the tightening belt 12. Or, one end of the tightening belt 12 can be fixed to the flexible belt 11, and the other end of the tightening belt 12 can be fixed on the winding shaft 141.

[0041] A fixing groove is provided on the winding shaft 141. The fixing groove is opened on the cylindrical surface of the winding shaft 141. The end of the tightening belt 12 is inserted into the fixing groove. A fastener is also passed through the winding shaft 141, and the fastener can clamp the winding belt between the fastener and the groove wall of the fixing groove. In addition, the tightening belt 12 can be adhesively fixed to the groove wall of the fixing groove to improve the fixing reliability of the tightening belt 12. In other examples, the tightening belt 12 can also be directly adhesively fixed to the cylindrical surface of the winding shaft 141.

[0042] The winding shaft 141 can also be connected to the driving member in the tightening assembly 14, facilitating the current user to control the winding or release of the tightening belt 12 with a single-handed operation. The winding shaft 141 can be connected to an electric driving member to rotate and wind up or release the tightening belt 12 under the driving force provided by the electric driving member; the current user can control the electric driving member to provide a driving force through an input module such as a mechanical button or a touch screen. Or, the winding shaft 141 can be connected to a manual driving member; the current user can provide a driving force to the winding shaft 141 through the manual driving member.

[0043] When the driving member drives the winding shaft 141 to wind the tightening belt 12 to the target position, the locking assembly 15 can lock the tightening assembly 14 and the mounting shell 13, so as to prevent the winding shaft 141 from rotating in the reverse direction to release the tightening belt 12 during the current user's use of the wearable device, which may affect the current user's wearing experience. Herein, winding the tightening belt 12 to the target position means that the space formed by the tightening belt 12 and the flexible belt 11 is exactly adapted to the wrist or upper limb of the current user.

[0044] Exemplarily, the fixed part of the locking assembly 15 is fixedly connected to the mounting shell 13, and the movable part of the locking assembly 15 can move relative to the mounting shell 13. When the tightening belt 12 is wound to the target position, the movable part of the locking assembly 15 can be moved under the driving force to cooperate with the fixed part of the locking assembly 15 and be relatively fixed, so as to restrict the rotation of the winding shaft 141 connected to the movable part of the locking assembly 15. When it is necessary to release the lock, the locking assembly 15 can be separated from the fixed part of the locking assembly 15 under the driving force in the reverse direction, and the locking of the winding shaft 141 of the tightening assembly 14 is released, so that the winding shaft 141 can be in a state of being able to rotate in different directions. Herein, the driving force can be an electric driving force or a manual driving force.

[0045] The fixing device 1 provided in this embodiment includes: a flexible belt 11; a tightening belt 12, the tightening belt 12 is threaded through the flexible belt 11, and the length direction of the tightening belt 12 is parallel to the length direction of the flexible belt 11; a mounting shell 13, the mounting shell 13 is connected to the end of the flexible belt 11; a tightening assembly 14, a part of the tightening assembly 14 is located in the mounting shell 13, the tightening assembly 14 is connected to the tightening belt 12, and the tightening assembly 14 is used for winding the tightening belt 12; a locking assembly 15, the locking assembly 15 is used for locking the tightening assembly 14 and the mounting shell 13 when the tightening assembly 14 winds the tightening belt 12 to the target position. In this way, the tightening assembly 14 can wind the tightening belt 12 until it adapts to the size of the wrist or upper limb of the current user, and the tightening assembly 14 can be locked by the locking assembly 15, so that the tightening belt 12 and the flexible belt 11 of the wearable device can be kept in a state adapted to the user's wrist or upper limb. Thus, the wearable device can be applicable to users of more age groups, and is simple and convenient to operate, with high wearing convenience.

[0046] In some embodiments, the tightening assembly 14 includes: a winding shaft 141 and a tightening driving member. The winding shaft 141 is located in the mounting shell 13, and the winding shaft 141 is fixedly connected to the end of the tightening belt 12; the tightening driving member is connected to the winding shaft 141, and the tightening driving member is used for driving the winding shaft 141 to rotate.

[0047] In some examples, the tightening driver may include a tightening knob 142, which is fixedly connected to the end of the winding shaft 141, and at least part of the tightening knob 142 is located outside the mounting shell 13.

[0048] The tightening knob 142 can be key-connected, welded or otherwise fixedly connected to the end of the winding shaft 141, as long as it can ensure that the tightening knob 142 can drive the winding shaft 141 to move synchronously. The winding shaft 141 can be connected to the mounting shell 13 through a bearing to facilitate ensuring the support reliability of the mounting shell 13 for the winding shaft 141.

[0049] The part of the tightening knob 142 located outside the mounting shell 13 constitutes an operation end for the user to operate. The tightening knob 142 is generally columnar, and the axial direction of the tightening knob 142 is parallel to the axial direction of the winding shaft 141. The operation end of the tightening knob 142 can be provided with a plurality of first protrusions spaced circumferentially along the tightening knob 142, and the first protrusions extend along the axial direction of the tightening knob 142 to facilitate user operation.

[0050] In other examples, the tightening driver can be a driving motor, and the output shaft of the driving motor can be connected to the winding shaft 141 through a transmission structure such as a coupling or a gear assembly; correspondingly, the driving motor is also electrically connected to the main control module 2 of the wearable device, and the user can control the working state of the driving motor through a mechanical button or a touch screen electrically connected to the main control module 2, and further control the winding or releasing of the tightening belt 12.

[0051] In this embodiment, by providing the winding shaft 141 and the tightening driver in the tightening assembly 14, the winding shaft 141 can rotate under the driving force provided by the tightening driver to wind or release the tightening belt 12, so that the space enclosed by the tightening belt 12 and the flexible belt 11 can be adapted to the user's wrist or upper limb. During the adjustment process, the user can complete it with one-handed operation, which has high convenience.

[0052] In some embodiments, the locking assembly 15 includes: a locking fixing member and a locking movable member. The locking fixing member is fixedly connected to the mounting shell 13, and the locking movable member is connected to the tightening assembly 14. When the winding shaft 141 winds the tightening belt 12 to the target position, the locking movable member is used to move towards the locking fixing member under an external force to cooperate with the locking member to lock the tightening assembly 14 and the mounting shell 13.

[0053] The mounting shell 13 is provided with a mounting hole, and the end of the winding shaft 141 can pass through the mounting hole. The locking fixing member can be fixedly connected to the hole wall of the mounting hole. Exemplarily, the locking fixing member can be adhesively connected or expanded-connected to the hole wall of the mounting hole or otherwise fixedly connected, as long as it can relatively fix the locking fixing member and the mounting shell 13.

[0054] The locking movable member can be installed on the winding shaft 141 of the tightening assembly 14. In the unlocked state, the locking movable member is relatively separated from the locking fixed member. When the winding shaft 141 needs to stop rotating, the locking movable member can move towards the locking fixed member under the action of a driving force until they cooperate with each other, and the locking fixed member can restrict the rotation of the winding shaft 141 connected to the locking movable member, so that the fixing device 1 is in a locked state.

[0055] In some examples, the locking fixed member includes an overrunning clutch 151. The overrunning clutch 151 is sleeved outside the winding shaft 141 of the tightening assembly 14 and has a clearance fit with the winding shaft 141. The outer ring of the overrunning clutch 151 is fixedly connected to the mounting shell 13.

[0056] In this way, by utilizing the characteristic that the overrunning clutch 151 cannot rotate bidirectionally, after the winding shaft 141 winds the tightening belt 12 to the target position, the above characteristic of the overrunning clutch 151 can be used to restrict the rotation of the locking movable member and the winding shaft 141 in the direction of releasing the tightening belt 12, so as to prevent the tightening belt 12 from loosening during the user's use. Moreover, after the winding shaft 141 winds the tightening belt 12 to the target position, due to the restriction of the user's wrist or upper limb, it is difficult for the winding shaft 141 to continue to rotate counterclockwise to wind the tightening belt 12. Therefore, the winding shaft 141 and the tightening belt 12 can be locked and held.

[0057] In the specific implementation process, when the locking movable member does not move to a state of cooperating with the overrunning clutch 151, the overrunning clutch 151 has no restrictive effect on the winding shaft 141, and the winding shaft 141 can rotate under the driving action of the tightening driving member. After the winding shaft 141 winds the tightening belt 12 to the target position and the locking movable member moves to cooperate with the overrunning clutch 151, the overrunning clutch 151 can restrict the rotation of the locking movable member and the winding shaft 141 in the direction of releasing the tightening belt 12, so as to prevent the tightening belt 12 from loosening during the user's use.

[0058] In some examples, a locking sleeve 153 is fixedly arranged in the central hole of the inner ring of the overrunning clutch 151. The locking sleeve 153 has a clearance fit with the winding shaft 141. When the winding shaft 141 winds the tightening belt 12 to the target position, the end face of the locking sleeve 153 facing the locking movable member can abut against the locking movable member to restrict the rotation of the locking movable member and the winding shaft 141.

[0059] The locking sleeve 153 can be fixedly connected to the inner ring of the overrunning clutch 151 by means of expansion joint, welding, interference fit or other fixed connection methods. There is a clearance between the hole wall of the central hole of the locking sleeve 153 and the cylindrical surface of the winding shaft 141 to avoid interfering with the rotation of the winding shaft 141.

[0060] The end face of the locking sleeve 153 facing the locking movable part may have a certain roughness. When the locking movable part moves to abut against the end face of the locking sleeve 153, there is a large frictional force between the end face of the locking sleeve 153 and the end face of the locking movable part, so as to limit the rotation of the locking movable part along the direction of releasing the tightening belt 12, and further limit the rotation of the winding shaft 141 connected to the movable locking part along the direction of releasing the tightening belt 12.

[0061] In other examples, when the winding shaft 141 winds the tightening belt 12 to the target position, the locking movable part can also directly abut against the overrunning clutch 151. Among them, in order to ensure the locking reliability, the end face of the overrunning clutch 151 facing the locking movable part can be processed so that the end face of the overrunning clutch 151 facing the locking movable part has a certain roughness.

[0062] Optionally, the locking movable part includes a locking knob 152, and the locking knob 152 is threadedly connected to the winding shaft 141. After the winding shaft 141 winds the tightening belt 12 to the target position, the user can turn the locking knob 152 so that the locking knob 152 can move towards the locking sleeve 153 until the end face of the locking knob 152 abuts against the end face of the locking sleeve 153. When unlocking is required, the user can turn the locking knob 152 in the direction of moving the locking knob 152 away from the locking sleeve 153.

[0063] In the specific implementation process, when the locking knob 152 has not moved to the state of abutting against the locking sleeve 153, the overrunning clutch 151 and the locking sleeve 153 have no restrictive effect on the winding shaft 141, and the winding shaft 141 can rotate under the driving action of the tightening driving part. After the winding shaft 141 winds the tightening belt 12 to the target position, the locking knob 152 can move to abut against the locking sleeve 153, and the overrunning clutch 151 and the locking sleeve 153 can limit the rotation of the locking knob 152 and the winding shaft 141 along the direction of releasing the tightening belt 12, so as to prevent the tightening belt 12 from loosening during the user's use.

[0064] In some examples, the locking knob 152 and the tightening knob 142 of the tightening assembly 14 are respectively located at opposite ends of the winding shaft 141.

[0065] In this way, it can be avoided that when the user turns one of the locking knob 152 and the tightening knob 142, the other of the locking knob 152 and the tightening knob 142 is accidentally touched. In addition, identifiers for identifying the locking knob 152 and identifiers for identifying the tightening knob 142 can be respectively set at corresponding positions of the installation shell 13 to facilitate the user to distinguish.

[0066] In other examples, the locking knob 152 and the tightening knob 142 can also be located at the same end of the winding shaft 141.

[0067] The part of the locking knob 152 located outside the mounting shell 13 forms an operating end for user operation. The locking knob 152 is generally columnar, and the axial direction of the locking knob 152 is parallel to the axial direction of the winding shaft 141. The operating end of the locking knob 152 may be provided with a plurality of second protrusion parts spaced circumferentially along the locking knob 152, and the second protrusion parts extend along the axial direction of the locking knob 152 to facilitate user operation.

[0068] In other embodiments, the locking and fixing member, such as the overrunning clutch 151, may be provided with a locking hole at one end facing the locking movable member, and the locking movable member is provided with a locking protrusion at one end facing the locking and fixing member. When locking is required, the locking movable member can slide towards the locking and fixing member under the action of the driving force until the locking protrusion is inserted into the locking hole. In addition, an elastic member is provided between the locking movable member and the shaft end of the mounting shell 13 or the winding shaft 141, and the elastic member can push the locking movable member along the direction towards the locking and fixing member to ensure that when locking is required, the locking movable member can slide towards the locking and fixing member under the action of the spring force until the locking protrusion is inserted into the locking hole and is reliably held. When unlocking is required, a force can be applied to the locking movable member to overcome the elastic force of the elastic member and move it in the direction away from the locking and fixing member until the locking movable member is separated from the locking and fixing member, so that the winding shaft 141 can rotate in any direction.

[0069] In some embodiments, the flexible belt 11 includes: an inner belt body 111 and an outer belt body 112, the inner belt body 111 and the outer belt body 112 are connected to form a fitting hole for the tightening belt 12 to pass through; a plurality of electrodes 16 are installed on the inner belt body 111. The electrodes 16 can be copper posts for sending the collected EMG signals to the main control module 2 of the wearable device.

[0070] Exemplarily, the outer belt body 112 may include a plurality of connecting strips, and the plurality of connecting strips are spaced along the length direction of the flexible belt 11; both ends of the connecting strip are folded towards the inner belt body 111 to form folding parts, and the folding parts can be connected to the corresponding longitudinal beams, and the longitudinal beams of the outer belt body 112 can be connected to the inner belt body 111 to form a fitting hole for the tightening belt 12 to pass through.

[0071] In other examples, the outer belt body 112 may include a flexible plate body, and two long sides of the flexible plate body are folded towards the inner belt body 111 to form folding parts, and the folding parts can be connected to the corresponding longitudinal beams.

[0072] The inner belt body 111 can be made of a skin-friendly material to improve the user experience. A plurality of electrodes 16 are installed on the inner belt body 111, and the electrodes 16 can be installed on the inner belt body 111 by fixing connection methods such as bonding, welding or plugging. Among them, the plurality of electrodes 16 can be distributed in a dot matrix, or the distribution of the electrodes 16 can be set according to actual needs.

[0073] For example, multiple electrodes 16 can be fixedly connected to the flexible board respectively. For example, multiple electrodes 16 are respectively welded to the flexible board, and multiple electrodes 16 can be electrically connected to the flexible board, and the flexible board is electrically connected to the main control module 12. Among them, a plurality of electrode holes corresponding to the electrodes 16 are provided on the inner layer belt body 111. The flexible board can be located outside the inner layer belt body 111. Multiple electrodes 16 are respectively inserted into the corresponding electrode holes, and a part of the electrode 16 can extend out of the electrode hole to ensure that the electrode 16 can reliably contact the user's skin. In this way, it is convenient for the electrode 16 to be assembled with the inner layer belt body 111, and the installation reliability of the electrode 16 can be ensured.

[0074] In some examples, the inner layer belt body 111 and the outer layer belt body 112 are fixedly connected by fasteners, and the fasteners can be common fasteners such as rivets. In other examples, the inner layer belt body 111 and the outer layer belt body 112 are snap-connected. For example, the inner layer belt body 111 is provided with a plurality of elastic snap blocks, and the plurality of elastic snap blocks are respectively snapped into the snap holes of the outer layer belt body 112. In still other examples, the inner layer belt body 111 and the outer layer belt body 112 can be integrally provided.

[0075] The tightening process and release process of the fixing device 1 provided in this embodiment will be described by way of example below.

[0076] When tightening is required, the user can rotate the tightening knob 142 counterclockwise. The tightening knob 142 drives the winding shaft 141 to rotate and wind up the tightening belt 12. The tightening belt 12 and the flexible belt 11 gradually fit the user's wrist or upper limb. When the electrode 16 installed on the inner layer belt body 111 in the flexible belt 11 is in close contact with the user's skin, it is determined that the tightening belt 12 is wound to the target position. At this time, restricted by the user's wrist or upper limb, it is difficult for the winding shaft 141 to continue rotating counterclockwise to wind up the tightening belt 12. Then, the user can rotate the locking knob 152 clockwise until the locking knob 152 abuts against the locking sleeve 153. The locking knob 152 cannot continue to rotate clockwise, and the winding shaft 141 linked to the locking knob 152 is restricted from continuing to rotate clockwise, thus preventing the winding shaft 141 from rotating in the direction of releasing the tightening belt 12 to avoid the problem of the tightening belt 12 loosening during use.

[0077] When the tightening belt 12 needs to be released, rotate the locking knob 152 counterclockwise so that the locking knob 152 is separated from the locking sleeve 153, releasing the restriction on the winding shaft 141. At this time, the user can directly pull both ends of the flexible belt 11 to quickly release the tightening belt 12 and achieve quick unlocking.
