Description

Technical Field

[0001] This invention relates to the field of smart wearable technology, and in particular to a smart wearable device. Background Technology

[0002] In smart wearable devices, to perceive the wearer's surroundings and enable interactive functions, various information-capturing components are typically integrated into the device, such as environmental cameras, depth sensors, and infrared detectors. These components form the core hardware foundation for functions like simultaneous localization and mapping (SLAM), gesture recognition, and eye tracking. Currently, these information-capturing components mostly adopt an exposed design, meaning the photosensitive surface or lens assembly is directly exposed to the outside of the device housing to ensure that the field of view is not obstructed by the structure, thereby maximizing the range of environmental information capture.

[0003] However, when the information capturing elements in the device are not in operation, the exposed information capturing elements are very susceptible to scratches on the lens and damage to the sensor due to drops, bumps, or friction with hard objects, which seriously affects the performance of the device.

[0010] In one embodiment, the second piezoelectric ceramic assembly includes two opposing piezoelectric strips disposed within the ring body, which can move toward each other or away from each other under the action of an electric field; The first side is provided with a first limiting post. In the hidden state, the two piezoelectric strips are clamped to the outer wall of the first limiting post to lock the hidden state, or the two piezoelectric strips are both moved away from the first limiting post to unlock the hidden state.

[0012] In one embodiment, the mounting plate is provided with two spaced-apart limiting grooves, and the two ends of the piezoelectric strip are respectively embedded in the two limiting grooves so that the piezoelectric strip can arch and deform between the two limiting grooves; And / or, the first limiting post is recessed with a first annular groove along its circumference, and in the hidden state, the two piezoelectric strips can be clamped in the first annular groove to lock the hidden state; And / or, the ends of the piezoelectric strip are provided with elastic elements, which are used to make the two ends of the piezoelectric strip tend to move closer to each other; And / or, the mounting plate is configured as a main control board, which is electrically connected to the piezoelectric strip and the fixing section respectively.

[0021] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0024] In smart wearable devices, to perceive the wearer's surroundings and enable interactive functions, various information-capturing components are typically integrated into the device, such as environmental cameras, depth sensors, and infrared detectors. These components form the core hardware foundation for functions like simultaneous localization and mapping (SLAM), gesture recognition, and eye tracking. Currently, these information-capturing components mostly adopt an exposed design, meaning the photosensitive surface or lens assembly is directly exposed to the outside of the device housing to ensure that the field of view is not obstructed by the structure, thereby maximizing the range of environmental information capture.

[0025] However, when the device is not in operation, such as when it is stored, carried, or used only in pure audio mode, the exposed information capturing components lack the necessary physical protection and are easily scratched by drops, bumps, or friction with hard objects, which seriously affects the device's performance and lifespan.

[0026] This invention proposes a smart wearable device.

[0027] Please see Figure 1 and Figure 2In one embodiment of the present invention, the smart wearable device includes a ring body 100, an actuation component 300, and an information collection component 200. The ring body 100 is worn on the human body; the actuation component 300 is installed on the ring body 100; the information collection component 200 is fixed to the actuation component 300, and the actuation component 300 is movable relative to the ring body 100 so that the information collection component 200 has a hidden state and a visible state; in the hidden state, the information collection component 200 is located inside the ring body 100; in the visible state, the information collection component 200 is exposed on the outside of the ring body 100.

[0028] Understandably, smart wearable devices can be smart glasses or smart headbands. Generally, an information acquisition device 200 is set on the smart glasses or smart headband to achieve different functions. For example, the information acquisition device 200 can acquire distance data of objects in front to construct a 3D point cloud map for obstacle avoidance and spatial measurement. Alternatively, it can acquire the texture and edge features of the ceiling, walls, and tabletop for real-time positioning and map building, allowing virtual objects to be stably superimposed on the real scene. Or, it can acquire the joint positions of the user's hands and arms to achieve bare-hand interactions such as clicking and swiping in the air. Of course, in other embodiments, the smart wearable device can also be a smart ring or a smart bracelet. In the solution shown in the figures of this invention, the smart wearable device is configured as a smart headband; the following description uses a smart headband as an example.

[0029] The ring body 100 is worn on the head. The ring body 100 can be an open ring structure or a closed ring structure. In one embodiment, to broaden the applicability of the smart wearable device, the circumferential length of the ring body 100 is adjustable.

[0030] The actuation component 300 is mounted on the ring body 100, and the information acquisition component 200 is fixed on the braking component. The information acquisition component 200 is used to collect information around the human head. The information acquisition component 200 can be a camera, sensor, etc., and the information it collects can be images of the surrounding environment or data parameters of the surrounding environment, such as temperature, humidity, height, distance, etc. The specific type of the information acquisition component 200 is not limited here.

[0031] The actuation component 300 can move relative to the ring body 100, thereby causing the information acquisition component 200 to move accordingly, allowing the information acquisition component 200 to have both a hidden state and a visible state. For example... Figure 4 As shown, when the information collection function of the information collection device 200 needs to be used, the smart wearable device can be removed first, allowing the actuation component 300 to move the information collection device 200 from the inside of the ring body 100 to the outside of the ring body 100, so that the information collection device 200 is exposed to the outside of the ring body 100, ensuring that the viewing angle is not obstructed by other structures and guaranteeing the range of environmental information capture. Figure 3 As shown, when the information collection function of the information collection component 200 is not needed, the smart wearable device can be removed first, so that the actuation component 300 can move the information collection component 200 from the outside of the ring body 100 to the inside of the ring body 100, thereby hiding the information collection component 200 and avoiding bumps and friction to the exposed information collection component 200. This helps to improve the protection of the information collection component 200, ensure the use effect and service life of the information collection component 200, and thus ensure the use effect and service life of the smart wearable device. At the same time, it also helps to improve the appearance of the smart wearable device.

[0032] The actuation component 300 can be either an automatic or a manual structure. For example, the actuation component 300 can be made of a flexible material that can be bent. When it is necessary to switch the position of the information acquisition component, force can be manually applied to the flexible material to drive the information acquisition component to switch states.

[0033] In addition, compared to retractably placing the information collection component 200 inside the ring body 100, in this invention, the information collection component 200 is hidden on the inner side of the ring body 100 and exposed on the outer side of the ring body 100. This avoids the complex internal structure of the ring body 100 and avoids interference between the information collection component 200 and other internal structures of the ring body 100, which is beneficial to the simplification of the structure of smart wearable devices.

[0034] The technical solution of this invention involves incorporating a ring body 100, an actuation component 300, and an information collection component 200 into a smart wearable device. The ring body 100 is worn on the human body; the actuation component 300 is installed on the ring body 100; and the information collection component 200 is fixed to the actuation component 300. The actuation component 300 is movable relative to the ring body 100, allowing the information collection component 200 to have both a hidden and a visible state. In the hidden state, the information collection component 200 is located inside the ring body 100; in the visible state, the information collection component 200 is exposed on the outside of the ring body 100. Thus, when the information collection component 200 is not in use, it can be hidden inside the ring body 100, thereby improving the protection of the information collection component 200 and ensuring its effectiveness and lifespan, which in turn ensures the effectiveness and lifespan of the smart wearable device.

[0035] In an embodiment of the present invention, the actuation component 300 is configured as a first piezoelectric ceramic component 301. The first piezoelectric ceramic component 301 can change its shape under the action of an electric field, and has a first shape and a second shape. In the first shape, the first piezoelectric ceramic component 301 drives the information acquisition component 200 to move to the inner side of the ring body 100. In the second shape, the first piezoelectric ceramic component 301 drives the information acquisition component 200 to move to the outer side of the ring body 100.

[0036] Specifically, in one embodiment, the actuation component 300 is configured as a first piezoelectric ceramic component 301. More specifically, the first piezoelectric ceramic component 301 may be a piezoelectric bicrystalline wafer. Understandably, under the influence of an electric field, one side of the piezoelectric ceramic elongates while the other side contracts along its thickness direction, thereby causing the piezoelectric ceramic to bend. Understandably, the bending shape of the first piezoelectric ceramic component 301 varies depending on the direction or strength of the electric field, resulting in a first shape and a second shape for the first piezoelectric ceramic component 301. It should be noted that different shapes include different bending angles and different bending directions.

[0037] In the first configuration, the first piezoelectric ceramic component 301 can move the information acquisition component 200 to the inside of the ring body 100, at which time the information acquisition component 200 is in a hidden state. In the second configuration, the first piezoelectric ceramic component 301 can move the information acquisition component 200 to the outside of the ring body 100, at which time the information acquisition component 200 is in a visible state.

[0038] In one embodiment, the actuation component 300 may partially employ piezoelectric ceramics and partially employ other bendable structures, such as flexible structures or bendable flexible structures. It is understood that the actuation component 300 can move between the inner side and the outer side of the ring body 100. This movement can be achieved entirely by electric drive, or it can be achieved through a combination of electric drive and manual movement by the user.

[0039] Of course, the actuation component 300 can also be made of piezoelectric polymer, piezoelectric composite material, etc. In other embodiments, the actuation component 300 can also adopt a magnetic structure, a mechanical structure, or a combination of multiple structures, and there are no limitations on this.

[0040] Please see Figure 3 and Figure 4 In an embodiment of the present invention, the first piezoelectric ceramic component 301 includes a fixed section 310 and a bendable section 320 connected to each other. The fixed section 310 is fixed to the ring body 100. The first piezoelectric ceramic component 301 includes a first side 321 and a second side 322 opposite to each other. The information acquisition component 200 is installed on the first side 321 and located in the bendable section 320. Under the influence of an electric field, the first side 321 contracts and the second side 322 extends. The bendable section 320 bends towards the inside of the ring body 100 relative to the fixed section 310, so that the first side 321 is opposite to the inner wall of the ring body 100, and the information acquisition device 200 switches to a hidden state; or, the first side 321 extends and the second side 322 contracts, and the bendable section 320 bends towards the outside of the ring body 100 relative to the fixed section 310, so that the second side 322 is opposite to the outer wall of the ring body 100, and the information acquisition device 200 switches to a visible state.

[0041] For ease of explanation, the first piezoelectric ceramic component 301 is defined to have a certain length, width, and thickness. Along the length direction of the first piezoelectric ceramic component 301, the first piezoelectric ceramic component 301 includes a fixed section 310 and a bendable section 320 connected to each other. The fixed section 310 is fixed to the ring body 100, and the bendable section 320 can be bent relative to the fixed section 310 under the action of an electric field.

[0042] Understandably, the ring body 100 has a mounting cavity. In one embodiment, the fixing segment 310 is fixed within the mounting cavity, and the bendable segment 320 extends out of the mounting cavity. In the embodiment shown in the figures of this invention, the fixing segment 310 is fixed to the outer wall of the mounting cavity, that is, to the cavity wall of the mounting cavity away from the center of the ring body 100. The fixing segment 310 can be fixed within the mounting cavity by means of screw fastening, snap-fitting, bonding, etc. Along the thickness direction of the first piezoelectric ceramic assembly 301, the first piezoelectric ceramic assembly 301 includes a first side 321 and a second side 322 opposite to each other. The information acquisition element 200 is mounted on the first side 321 and located on the bendable segment 320. In one embodiment, the information acquisition element 200 is disposed near the free end of the bendable segment 320.

[0043] Understandable, such as Figure 3 As shown, under the influence of an electric field, the first side 321 contracts, and the second side 322 extends. The bendable section 320 bends towards the inside of the ring body 100 relative to the fixed section 310 until the first side 321 is face-to-face with the inner wall of the ring body 100. At this time, the information acquisition component 200 is in a hidden state. That is, when viewed from the inside of the ring body 100, only the second side 322 of the bendable section 320 is visible, while the information acquisition component 200 is located on the first side 321 and is thus hidden, avoiding exposure of the information acquisition component 200 and protecting it.

[0044] like Figure 4As shown, under the influence of an electric field, the first side 321 extends, and the second side 322 contracts. The bendable section 320 bends outward relative to the fixed section 310 towards the outside of the ring body 100 until the second side 322 is positioned face-to-face with the outer wall of the ring body 100. At this point, the first side 321 is exposed on the outside of the ring body 100. Thus, the information acquisition component 200 of the first side 321 is exposed on the outside of the ring body 100, thereby enabling the acquisition of information about the surrounding environment. Therefore, by controlling the electric field, the inward or outward bending of the bendable section 320 relative to the fixed section 310 can be controlled, thereby switching between the hidden and exposed states of the information acquisition component 200.

[0045] In embodiments of the present invention, the smart wearable device further includes a locking component 400 disposed on the ring body 100. The locking component 400 is used to lock or unlock a hidden state, and / or, to lock or unlock a visible state. Thus, when it is necessary to maintain a hidden state and / or a visible state, the locking component 400 locks that state; when it is necessary to switch between a hidden state and / or a visible state, the locking component 400 unlocks the state, thereby improving the stability of the hidden and visible states.

[0046] In an embodiment of the present invention, the locking component 400 includes a second piezoelectric ceramic component 401 disposed within the ring body 100. The second piezoelectric ceramic component 401 locks or unlocks the bendable section 320 to lock or unlock the second piezoelectric ceramic component 401 in a hidden state and in a visible state.

[0047] Specifically, in one embodiment of the present invention, the locking component 400 includes a second piezoelectric ceramic component 401, thereby utilizing the piezoelectric properties of the piezoelectric ceramic to achieve locking and unlocking of the locking component 400. Of course, in other embodiments, the locking component 400 can also be configured as a magnetic structure, a mechanical structure, etc., wherein the mechanical structure can include a structure including a motor, a transmission rod, a latch, etc., and the motor controls the locking and unlocking of the latch, thereby achieving locking and unlocking. The second piezoelectric ceramic component 401 acts on the bendable section 320, and by locking or unlocking the bendable section 320, the state of the information acquisition component 200 is locked or unlocked.

[0048] In one embodiment of the present invention, the second piezoelectric ceramic component 401 can achieve both locked and unlocked hidden states as well as locked and unlocked exposed states. Thus, by setting a set of locking components 400, both hidden and exposed states can be locked or unlocked simultaneously, which is beneficial for simplifying the structure of smart wearable devices.

[0049] Please see Figure 3 and Figure 5In an embodiment of the present invention, the second piezoelectric ceramic component 401 includes two opposing piezoelectric strips 410 disposed within the ring body 100. Under the action of an electric field, the two piezoelectric strips 410 can move toward each other or toward each other. The first side 321 is provided with a first limiting post 330. In the hidden state, the two piezoelectric strips 410 are clamped on the outer wall of the first limiting post 330 to lock the hidden state, or the two piezoelectric strips 410 are both moved away from the first limiting post 330 to unlock the hidden state.

[0050] Specifically, such as Figure 6 As shown, the second piezoelectric ceramic assembly 401 includes two piezoelectric strips 410, which are arranged opposite to each other. Under the action of an electric field, the two piezoelectric strips 410 can move towards or away from each other. A first limiting post 330 is provided on the first side 321, which protrudes from the surface of the first side 321, that is, the axial direction of the first limiting post 330 is parallel to the thickness direction of the first piezoelectric ceramic assembly 301.

[0051] Two piezoelectric strips 410 are installed in the mounting cavity of the ring body 100. When switching from a visible state to a hidden state, the first side 321 bends towards the two piezoelectric strips 410, so that the first limiting post 330 can be positioned face-to-face with the two piezoelectric strips 410. When the bendable section 320 is located inside the ring body 100, the first limiting post 330 is located between the two piezoelectric strips 410. When it is necessary to lock the hidden state, the two piezoelectric strips 410 are driven to move towards each other, so that the two piezoelectric strips 410 can clamp the opposite sides of the first limiting post 330, thereby fixing the first limiting post 330 and restricting the bending of the bendable section 320 relative to the fixed section 310, thus locking the hidden state. When it is necessary to switch to the exposed state, the two piezoelectric strips 410 are driven to move away from each other, thereby releasing the first limiting post 330. At this time, the first piezoelectric ceramic component 301 is driven, so that the bendable section 320 bends relative to the fixed section 310, and the exposed state can be switched.

[0052] Please see Figure 6 and Figure 7 In an embodiment of the present invention, a mounting plate 420 is provided inside the ring body 100, and a piezoelectric strip 410 is mounted on the mounting plate 420. The mounting plate 420 is provided with a first limiting hole 422, and the first limiting hole 422 is located between two piezoelectric strips 410. In the hidden state, at least a portion of the first limiting post 330 extends into the first limiting hole 422.

[0053] Specifically, in one embodiment, a mounting plate 420 is fixed inside the ring body 100. The mounting plate 420 is installed along the circumference of the ring body 100, that is, the thickness direction of the mounting plate 420 is approximately parallel to the radial direction of the ring body 100. The mounting plate 420 can be fixed inside the ring body 100 by means of screw fastening, snap-fit, etc.

[0054] The mounting plate 420 is provided with a first limiting hole 422, the axial direction of which is parallel to the thickness direction of the mounting plate 420. Two piezoelectric strips 410 are spaced apart on the mounting plate 420 and are located on opposite sides of the first limiting hole 422. When switched to the hidden state, at least a portion of the first limiting post 330 can extend into the first limiting hole 422. This ensures that the first piezoelectric ceramic assembly 301 can be accurately positioned every time it is switched to the hidden state, guaranteeing consistent performance each time. Simultaneously, the first limiting hole 422 limits the radial movement of the first limiting post 330, and the two piezoelectric strips 410 restrict both the radial and axial movements of the first limiting post 330. The first limiting hole 422 further improves the limiting stability of the first limiting post 330 and enhances the locking stability in the hidden state.

[0055] like Figure 4 As shown, in one embodiment, to ensure the aesthetics of the structure, a cover plate 520 is also installed on the inner side of the ring body 100. The cover plate 520 covers the inner side of the mounting plate 420, that is, the main control board 421, to shield the piezoelectric strips 410 and other structures. To ensure that the first limiting post 330 can at least partially extend into the first limiting hole 422, and that the two piezoelectric strips 410 can be clamped on opposite sides of the first annular groove 331, the cover plate 520 is provided with a through third limiting hole 521. The third limiting hole 521 is arranged opposite to the first limiting hole 422, so that in the hidden state, at least part of the first limiting post 330 can pass through the third limiting hole 521 and extend into the first limiting hole 422. The structure of the first annular groove 331 is described in detail below.

[0056] Please see Figure 6 and Figure 7 In an embodiment of the present invention, the mounting plate 420 is provided with two spaced-apart limiting grooves 423, and the two ends of the piezoelectric strip 410 are respectively embedded in the two limiting grooves 423 so that the piezoelectric strip 410 can arch and deform between the two limiting grooves 423.

[0057] In one embodiment, the direction of the connecting line of the two limiting grooves 423 is parallel to the length direction of the piezoelectric strip 410. The openings of the two limiting grooves 423 are arranged opposite each other, so that both ends of the piezoelectric strip 410 in the length direction can respectively extend into the two limiting grooves 423. It can be understood that the two limiting grooves 423 are spaced apart, so that the portion between the two ends of the piezoelectric strip 410 can be exposed outside the limiting grooves 423, thus facilitating the deformation of the piezoelectric strip 410.

[0058] Understandably, this invention includes two spaced-apart piezoelectric strips 410, and correspondingly, two sets of limiting grooves 423 are also provided. One set of limiting grooves 423 includes two limiting grooves 423 spaced apart along the length of the piezoelectric strip 410. The two ends of one piezoelectric strip 410 are embedded in one set of limiting grooves 423, and the two ends of the other piezoelectric strip 410 are embedded in the other set of limiting grooves 423.

[0059] In one embodiment, two limiting grooves 423 located at the same end along the length of the two piezoelectric strips 410 are connected to facilitate the setting of the limiting grooves 423. Specifically, in one embodiment, a limiting frame is provided on the mounting base. The limiting frame includes a first limiting strip and a second limiting strip arranged opposite to each other, and a third limiting strip connecting the first limiting strip and the second limiting strip. The first limiting strip, the second limiting strip, and the third limiting strip enclose a limiting space. A limiting block is provided in the limiting space. The limiting block is spaced apart from the first limiting strip, the second limiting strip, and the third limiting strip, thereby forming a limiting groove 423 for embedding one piezoelectric strip 410 between the limiting block and the first limiting strip, and another limiting groove 423 for embedding another piezoelectric strip 410 between the limiting block and the second limiting strip. This facilitates the simplification of the structure of the limiting grooves 423.

[0060] Please see Figure 5 In one embodiment, a first annular groove 331 is recessed circumferentially at one end of the first limiting post 330 near its free end. In the hidden state, the free end of the first limiting post 330 extends into the first limiting hole 422 at the position of the first annular groove 331 facing the free end in the axial direction of the first limiting post 330, but the first annular groove 331 does not extend into the first limiting hole 422. When the second piezoelectric ceramic assembly 401 locks the first limiting post 330, the two piezoelectric strips 410 are clamped in the first annular groove 331. Thus, the provision of the first annular groove 331 is beneficial to the clamping stability of the piezoelectric strips 410 on the first limiting post 330, further improving the stability in the hidden state.

[0061] Understandably, the piezoelectric strip 410 has a certain length, width, and thickness, and its two ends are embedded in the limiting groove 423 along the length direction of the piezoelectric strip 410. In one embodiment, in order to ensure the clamping contact area of ​​the piezoelectric strip 410 with the first limiting post 330 and to ensure the locking effect of the piezoelectric strip 410 with the first limiting post 330, in one embodiment, the width surface of the piezoelectric strip 410 is made to clamp and contact the first limiting post 330, thereby further improving the locking stability in the hidden state.

[0062] Please see Figure 6 In one embodiment, the piezoelectric strip 410 has an elastic element 510 at its end, which is used to make the two ends of the piezoelectric strip 410 tend to move closer to each other. Understandably, under the action of an electric field, the two piezoelectric strips 410 can deform in a direction that moves closer or further away from each other. During the deformation process, the piezoelectric strip 410 can arch outwards to move away from the other, or return to a straight shape to move closer to the other, or even arch inwards to move further closer to the other. During this deformation process, the two ends of the piezoelectric strip 410 will move closer or further away from each other. In one embodiment, an elastic element 510 is installed at at least one end of the piezoelectric strip 410. The elastic element 510 can be compressed when subjected to pressure from the end of the piezoelectric strip 410, and can return to its original shape after the pressure is released. This causes the two ends of the piezoelectric strip 410 to tend to move closer together, thus avoiding hard contact with other components during the deformation of the ends of the piezoelectric strip 410, which helps protect the piezoelectric strip 410. At the same time, the elastic element 510 facilitates the switching of the release state of the first limiting post 330.

[0063] In one embodiment, each piezoelectric strip 410 has an elastic element 510 at both ends. Furthermore, an elastic element 510 is provided at the same end of the two piezoelectric strips 410, which acts on the two piezoelectric strips 410, thus further simplifying the structure of the smart wearable device.

[0064] Specifically, in one embodiment, the elastic element 510 is installed between the limiting block and the third limiting strip. In one embodiment, the limiting frame is open on the side opposite to the mounting plate 420 to facilitate the installation of the elastic element 510 and the piezoelectric strip 410. In one embodiment, the elastic element 510 is configured as silicone, rubber, or a spring sheet, etc., and the specific type of the elastic element 510 is not limited here.

[0065] Please see Figure 4 and Figure 7In one embodiment, the mounting plate 420 is configured as a main control board 421, which is electrically connected to the piezoelectric strip 410 and the fixing section 310, respectively. This allows the piezoelectric strip 410 to be directly mounted on the main control board 421, avoiding the need for an additional mounting plate 420 and an additional electrical connection between the main control board 421 and the piezoelectric strip 410, thus simplifying the structure. In one embodiment, the thickness surface of the piezoelectric strip 410 contacts and maintains an electrical connection with the main control board 421; that is, the piezoelectric strip 410 remains electrically connected to the main control board 421 throughout its deformation. In another embodiment, the main control board 421 has an outwardly extending electrical connection portion 424, through which it is electrically connected to the fixing section 310.

[0066] Please see Figure 3 and Figure 4 In an embodiment of the present invention, the outer side wall of the ring body 100 is provided with a second limiting hole 110 communicating with the first limiting hole 422, and the second side 322 is provided with a second limiting post 340; in the exposed state, at least a portion of the second limiting post 340 extends into the second limiting hole 110 and the first limiting hole 422, so that the two piezoelectric strips 410 clamp or release the second limiting post 340 to lock or release the exposed state.

[0067] Specifically, the outer wall of the ring body 100 is provided with a second limiting hole 110, which is connected to the first limiting hole 422. That is, the first limiting hole 422 is provided through the mounting plate 420, and the second limiting hole 110 is provided through the outer wall of the ring body 100, so that the first limiting hole 422 and the second limiting hole 110 can be connected.

[0068] Thus, in the exposed state, the bendable section 320 moves to the outside of the ring body 100, and the second side 322 is positioned face-to-face with the outer wall of the ring body 100. At least a portion of the second limiting post 340 passes through the second limiting hole 110 and extends into the first limiting hole 422, thereby restricting the radial movement of the second limiting post 340. At this time, the free end of the second limiting post 340 can extend toward the side of the mounting plate 420 where the piezoelectric strip 410 is provided. Thus, by clamping or releasing the second limiting post 340 with the two piezoelectric strips 410, the radial and axial movements of the second limiting post 340 are restricted. In this way, by clamping the second limiting post 340 with the piezoelectric strips 410, the stability of the exposed state is improved, ensuring the stability of the data acquisition effect of the information acquisition device 200.

[0069] In embodiments of the present invention, the heights of the first limiting post 330 and the second limiting post 340 are approximately equal. That is, the distance from the free end of the first limiting post 330 to the first side 321 is approximately equal to the distance from the free end of the second limiting post 340 to the second side 322. Thus, in both the exposed and concealed states, the height of the bendable segment 320 in the first piezoelectric ceramic assembly 301 is approximately equal to the height of the inner wall of the ring body 100 and the height of the outer wall of the ring body 100, which facilitates consistent appearance height of the bendable segment 320 in both states. Note that "approximately equal height" means that the heights of the two segments are not significantly different, not that they are absolutely equal.

[0070] Furthermore, in one embodiment, the distance between the first annular groove 331 and the first side 321 is comparable to the distance between the second annular groove 341 and the second side 322. This further facilitates that the height of the bendable segment 320 is comparable to the height of the inner or outer sidewall of the ring body 100 in both states.

[0071] Please see Figure 2 In an embodiment of the present invention, the ring body 100 is provided with a mounting recess 120, and the actuation component 300 is mounted in the mounting recess 120; in the hidden state, the second limiting post 340 does not protrude from the inner sidewall of the ring body 100.

[0072] Understandably, to prevent the actuation component 300 from protruding from the outer surface of the ring body 100, in one embodiment, a mounting recess 120 is provided on the ring body 100 for mounting the actuation component 300. Further, the mounting recess 120 may be located on the inner and / or outer side of the ring body 100. In one embodiment, the mounting recess 120 is at least located on the inner side of the ring body 100, and in the concealed state, the free end of the second limiting post 340 does not protrude from the plane containing the inner sidewall of the ring body 100. Thus, when wearing the smart wearable device, the inner sidewall of the ring body 100 contacts the human head, and the second limiting post 340 does not contact the head, thereby avoiding pressure on the head from the second limiting post 340 and improving the comfort of using the smart wearable device.

[0073] In an embodiment of the present invention, the information acquisition device 200 is configured as a camera module, which is used to capture images around the human head. Of course, in other embodiments, the information acquisition device 200 may also be a sensor or the like.

[0074] In embodiments of the present invention, multiple actuation components 300 and multiple information acquisition components 200 are provided, with each information acquisition component 200 corresponding to one of the multiple actuation components 300; the multiple actuation components 300 are spaced apart along the circumference of the ring body 100. This one-to-one correspondence between the multiple information acquisition components 200 and the multiple actuation components 300 is beneficial to the accuracy and comprehensiveness of information acquisition.

[0075] In embodiments of the present invention, the smart wearable device is configured as a head-mounted display device. Specifically, it can be a smart headband, smart glasses, a smart helmet, etc.
