[0023] The following is combined Figures 1-8 A wearable device according to an embodiment of the present invention is described.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a wearable device according to some embodiments of the present invention includes: a strap 6; a display unit 2, the display unit 2 including a fixing component 20 and a display component 22, the fixing component 20 being connected to the strap 6, the display component 22 having a display screen 220; the display component 22 being movably connected to the fixing component 20 to adjust the position of the display screen 220 relative to the fixing component 20.

[0025] In embodiments of this application, the wearable device includes a strap 6 and a display unit 2. The display unit 2 has a fixing component 20 and a display component 22. The strap 6 is connected to the fixing component 20 for easy wearing. The display component 22 is movably connected to the fixing component 20, allowing the display component 22 to move relative to the fixing component 20. This allows adjustment of the position of the display component 22 relative to the fixing component 20, and consequently, the position of the display component 22 relative to the wearer 5, so that the display component 22 can be adjusted to a comfortable position for the wearer 5.

[0026] In specific applications, the direction of movement of the display component 22 relative to the fixed component 20 can be set according to the actual situation. Specifically, the display component 22 can move linearly relative to the fixed component 20.

[0027] Furthermore, such as Figure 1 As shown, the display component 22 moves left or right relative to the fixed component 20, or the display component 22 moves up or down relative to the fixed component 20.

[0028] Specifically, the display component 22 moves relative to the fixed component 20 along the extension direction of the line connecting the user's eyes, thereby enabling the display component 22 to move left and right relative to the fixed component 20. The display component 22 also moves relative to the fixed component 20 in a direction perpendicular to the line connecting the user's eyes, thereby enabling the display component 22 to move up and down relative to the fixed component 20.

[0029] It is understandable that the display component 22 is slidably connected to the fixed component 20.

[0030] According to one embodiment of this application, the display component 22 includes two displays 220, and the display component 22 is moved along the line connecting the centers of the two displays 220 to adjust the position of the display component 22 relative to the fixed component 20.

[0031] In this embodiment, the display component 22 includes two displays 220. The display component 22 and the fixing component 20 are movably connected along the line connecting the centers of the two displays 220, so that the display component 22 can move relative to the fixing component 20 in the line connecting the centers of the two displays 220, thereby adjusting the position of the display component 22 relative to the fixing component 20, so that the position of the display component 22 relative to the wearer 5 changes, so as to facilitate wearing.

[0032] It should be noted that the center of the two displays 220 can be the geometric center of the displays 220 or the alignment center point of the displays 220.

[0033] According to one embodiment of this application, the wearable device is wearable glasses, and the display screen 220 is used to face the human eye. The position of the display component 22 relative to the fixed component 20 is adjusted so that the center of the human eye is facing the center of the display screen 220.

[0034] In this embodiment, the wearable device is wearable glasses. When the wearer 5 wears the wearable glasses, the display screen 220 can be positioned opposite the wearer's eyes so that the wearer 5 can view the content on the display screen 220. During the movement of the display component 22 relative to the fixed component 20, both displays 220 move relative to the fixed component 20, thereby adjusting the position of the display screen 220 relative to the wearer's eyes so that the center of the display screen 220 is aligned with the center of the wearer's eyes, thus improving eye comfort.

[0035] It should be noted that the center of the two displays 220 can be the geometric center of the displays 220 or the alignment center point of the displays 220.

[0036] Specifically, the display component 22 can move left and right relative to the fixed component 20 in the direction of the line connecting the centers of the two displays 220, thereby adjusting the left and right distance between the display component 22 and the eyes of the wearer 5, so that the center of the display 220 is aligned with the center of the pupil of the eye, so as to improve eye comfort.

[0037] In specific applications, such as Figure 2As shown, the fixing component 20 and the clamping part 1 are connected in a ring shape by the strap 6. When worn, the display screen 220 corresponds to the wearer's eyes. Furthermore, the distance between the centers of the two display screens 220 is the same as the distance between the pupils of the wearer's two eyes.

[0038] Specifically, such as Figure 1 As shown, L1 represents the distance between the centers of the two displays 220, and L2 represents the distance between the pupils of the wearer 5's two eyes. With L1 and L2 being the same length, the display assembly 22 is moved as a whole so that the centers of the two displays 220 correspond to the centers of the wearer 5's pupils.

[0039] According to one embodiment of this application, one of the display component 22 and the fixing component 20 is provided with a protrusion 204, and the other is provided with a slide groove 223; the display component 22 is movably connected to the fixing component 20 through the protrusion 204 and the slide groove 223; the wearable device also includes a driving component 4, which is connected to the fixing component 20 and / or the display component 22, and is used to adjust the position of the display component 22 relative to the fixing component 20.

[0040] In this embodiment, the wearable device further includes a driving component 4, which is connected to at least one of the fixing component 20 and the display component 22. The driving component 4 is used to drive the fixing component 20 to move relative to the display component 22 and / or to drive the display component 22 to move relative to the fixing component 20, thereby changing the position of the display component 22 relative to the fixing component 20 to adjust the position of the display component 22. The fixing component 20 and the display component 22 are movably connected through the cooperation of a protrusion 204 and a sliding groove 223. The cooperation between the protrusion 204 and the sliding groove 223 is simple in structure, reliable in connection, and easy to manufacture.

[0041] It is understood that the drive component 4 and the fixed component 20 are slidably connected by the protrusion 204 and the groove 223.

[0042] In specific applications, drive component 4 includes motor drive or knob screw drive.

[0043] like Figure 3 , Figure 4 and Figure 8 As shown, according to one embodiment of this application, the display component 22 has a groove 223 on the side facing the fixed component 20, and the fixed component 20 has a protrusion 204 on the side facing the display component 22. The protrusion 204 is inserted into the groove 223 for limiting the position. The wearable device also includes a driving component 4, which includes a driving member. The driving member is connected to the display component 22 to drive the display component 22 to move relative to the fixed component 20.

[0044] In this embodiment, the display component 22 is provided with a sliding groove 223, and the fixing component 20 is provided with a protrusion 204. The protrusion 204 is inserted into the sliding groove 223 to limit the position between the fixing component 20 and the display component 22, preventing the display component 22 from falling off the fixing component 20. The driving component 4 includes a driving member connected to the display component 22. By operating the driving member, the display component 22 moves relative to the fixing component 20, thereby adjusting the position of the display component 22 relative to the fixing component 20 for easy wearing.

[0045] In one possible design, the position of the display component 22 relative to the fixed component 20 can be adjusted manually, that is, the user directly pushes and pulls the display component 22, causing the display component 22 to move left and right relative to the fixed component 20. In this driving method, the driving component 4 includes a push-pull part for manual adjustment by the user and a locking structure disposed on the display component 22 or the fixed component 20. The locking structure is used to lock the relative position of the display component 22 and the fixed component 20, so that the relative position of the display component 22 is locked after the relative position of the display component 22 and the fixed component 20 has been adjusted.

[0046] According to one embodiment of this application, the driving component includes a lead screw 40 and a knob 44. The display assembly 22 has a mounting cavity 226 that engages with the lead screw 40. The knob 44 is located outside the display assembly 22. The lead screw 40 is connected to the knob 44. When the knob 44 is rotated, the lead screw 40 drives the display assembly 22 to move along the extension direction of the slide groove 223.

[0047] In this embodiment, the driving component includes a lead screw 40 and a knob 44 connected to each other. The knob 44 is located outside the display component 22, and the lead screw 40 extends into the mounting cavity 226 of the display component 22. The inner wall surface of the mounting cavity 226 can cooperate with the lead screw 40. Thus, during the rotation of the knob 44, the knob 44 drives the lead screw 40 to move. Through the engagement of the lead screw 40 with the mounting cavity 226, the display component 22 is driven to move along the extension direction of the slide groove 223, thereby causing the protrusion 204 to move relative to the slide groove 223, and thus causing the display component 22 to move relative to the fixed component 20 to adjust the position of the display component 22 relative to the wearer 5.

[0048] In practical applications, the extension direction of the slide 223 is the same as the direction of the line connecting the centers of the two displays 220.

[0049] like Figure 6 As shown, according to one embodiment of this application, the groove 223 includes an opening 2230 and a bottom wall 2232 disposed opposite to each other. The area of ​​the opening 2230 is smaller than the area of ​​the bottom wall 2232, and the area of ​​the end of the protrusion 204 near the bottom wall 2232 is larger than the area of ​​the end of the protrusion 204 near the opening 2230.

[0050] In this embodiment, the slide groove 223 includes an opening 2230 and a bottom wall 2232 disposed opposite to each other. The area of ​​the opening 2230 is smaller than the area of ​​the bottom wall 2232. Correspondingly, the cross-sectional area of ​​one end of the protrusion 204 is smaller than the cross-sectional area of ​​the other end. Thus, when the protrusion 204 is connected to the slide groove 223, the protrusion 204 can be locked in the slide groove 223, preventing the protrusion 204 from coming out of the slide groove 223.

[0051] It is understandable that, along the line connecting the centers of the two displays 220, the protrusion 204 extends into the slide groove 223 from one end of the slide groove 223, thereby ensuring that the protrusion 204 is slidably connected to the slide groove 223 while preventing the protrusion 204 from disengaging from the slide groove 223, thus improving the reliability of the movement of the display component 22.

[0052] The opening 2230 corresponds to the end of the protrusion 204 with a smaller cross-sectional area, and the bottom wall 2232 of the groove 223 corresponds to the end of the protrusion 204 with a larger cross-sectional area.

[0053] like Figure 7 As shown, according to one embodiment of this application, the groove 223 includes a dovetail groove.

[0054] In this embodiment, the slide groove 223 includes a dovetail groove. The dovetail groove cooperates with the protrusion 204 to prevent the protrusion 204 from falling off the slide groove 223, thereby ensuring the reliability of the connection between the display component 22 and the fixing component 20.

[0055] It is understandable that, in the cross section perpendicular to the connecting line, the dovetail groove has an isosceles trapezoidal cross section.

[0056] In specific applications, the fixed component 20 is provided with a protrusion 204, and the display component 22 is provided with a sliding groove 223. Further, the display component 22 is provided with a mounting groove 224, and the display component 22 includes a stop 222, which is disposed in the mounting groove 224, and the sliding groove 223 is disposed in the stop 222; along the connecting line direction, the length of the sliding groove 223 is greater than the length of the protrusion 204.

[0057] In this embodiment, the display component 22 is provided with a mounting groove 224, and the stop portion 222 is disposed within the mounting groove 224, shortening the distance between the display component 22 and the fixing component 20, thereby shortening the distance between the display screen 220 and the wearer's eyes 5, thus improving eye comfort. The length of the sliding groove 223 is greater than the length of the protrusion 204, allowing the protrusion 204 to slide within the sliding groove 223, preventing the protrusion 204 from disengaging from the sliding groove 223 in the sliding direction. Simultaneously, setting the length of the sliding groove 223 to be greater than the length of the protrusion 204 prevents the protrusion 204 from being exposed during the movement of the display component 22, improving the aesthetics of the wearable device.

[0058] In practical applications, the slide groove 223 extends through both ends of the stop portion 222 along the sliding direction of the protrusion 204 and the slide groove 223. The stop portion 222 is disposed within the mounting groove 224, and its two ends respectively abut against the two ends of the mounting groove 224 along the sliding direction of the protrusion 204. By adding the stop portion 222, providing the slide groove 223 on the stop portion 222, and installing the stop portion 222 within the mounting groove 224, it is possible to prevent the protrusion 204 from detaching from the slide groove 223 during movement, and also to facilitate the installation of the display component 22 and the fixing component 20. Specifically, during installation, the protrusion 204 is first connected to the slide groove 223, and then the stop portion 222 is installed within the mounting groove 224. During the movement of the protrusion 204 and the slide groove 223, it is possible to prevent the protrusion 204 from detaching from the slide groove 223.

[0059] Furthermore, the stop portion 222 is connected to the display component 22 by screws.

[0060] It is understandable that the stop portion 222 is block-shaped and has a sliding groove 223 on it, that is, the display component 22 and the stop portion 222 are two separate parts. Of course, the sliding groove 223 can also be directly formed on the display component 22.

[0061] In one possible design, the length of the protrusion 204 is greater than the length of the groove 223, so that the groove 223 can slide along the length direction of the protrusion 204. Furthermore, stop structures are provided at both ends of the protrusion 204 to prevent the protrusion 204 from disengaging from the groove 223. Alternatively, in this design, the groove 223 can be directly formed on the display component 22, and the groove 223 can pass through both ends of the display component 22 along the connecting line direction.

[0062] It is understandable that the length direction of the protrusion 204 is the same as the direction of the connecting line.

[0063] According to one embodiment of this application, the driving component 4 further includes a reset member 42, which is clamped between the protrusion 204 and the sidewall of the slide groove 223 to push the display component 22 to reset.

[0064] In this embodiment, the driving component 4 further includes a reset member 42, which is located between the protrusion 204 and the side wall of the slide groove 223. During the process of the driving component driving the display component 22 to move relative to the fixed component, the reset member 42 deforms. Then, when the driving component stops driving the display component 22, the deformation of the reset member 42 can drive the display component 22 to move relative to the fixed component 20, thereby resetting the display component 22.

[0065] In a specific application, when the driving component includes a lead screw 40, the reset component 42 and the lead screw 40 are located at both ends of the protrusion 204. In this way, the display component 22 can move left and right relative to the fixed component 20 through the combined action of the lead screw 40 and the reset component 42.

[0066] It is understandable that the lead screw 40 can drive the display component 22 to move the slide groove 223 relative to the protrusion 204 on one side of the sliding direction. Through the elastic action of the reset member 42, the slide groove 223 can be driven to move relative to the protrusion 204 on the other side of the sliding direction, thereby realizing the movement of the display component 22 relative to the fixed component 20 in the left and right directions.

[0067] In a specific application, the reset element 42 includes a spring.

[0068] Furthermore, the spring is a compression spring.

[0069] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, according to one embodiment of this application, the protrusion 204 has a first side and a second side, which are distributed along the extending direction of the slide groove 223; the driving member includes a lead screw 40, and the display assembly 22 has a mounting cavity 226 that engages with the lead screw 40. The mounting cavity 226 communicates with the side wall of the slide groove 223, and the lead screw 40 extends into the slide groove 223 and abuts against the first side of the protrusion 204; the driving assembly 4 also includes a reset member 42, which includes an elastic member. One end of the elastic member is connected to the inner wall of the slide groove 223, and the other end of the elastic member is connected to the second side of the protrusion 204; the lead screw 40 and the elastic member drive the display assembly 22 to move relative to the protrusion 204 along the extending direction of the slide groove 223.

[0070] In this embodiment, the drive assembly 4 includes a drive member and a reset member 42. The drive member includes a lead screw 40, and the reset member 42 includes an elastic member. The protrusion 204 has a first side and a second side, which are distributed along the extension direction of the slide groove 223. The first side and the second side are two opposite sidewalls of the protrusion 204. The mounting cavity 226, which engages with the lead screw 40, is connected to the slide groove 223, so that one end of the lead screw 40 that extends into the mounting cavity 226 can extend into the slide groove 223 and abut against the first side of the protrusion 204. Correspondingly, one end of the elastic member is connected to the inner wall of the slide groove 223, and the other end is connected to the second side of the protrusion 204. In this way, the lead screw 40 can drive the display component 22 to move in the direction of compressing the elastic member, and the elastic member can drive the display component 22 to move in the direction of the lead screw 40. Thus, through the cooperation of the lead screw 40 and the elastic member, the display component 22 can move left and right relative to the fixed component 20 in the extension direction of the slide groove 223.

[0071] like Figure 6 and Figure 8 As shown, according to one embodiment of this application, the display component 22 is provided with a mounting cavity 226, and the mounting cavity 226 is provided with an internal thread 227; the lead screw 40 passes through the mounting cavity 226, and the lead screw 40 is provided with an external thread 402, which meshes with the internal thread 227. The two ends of the lead screw 40 protrude from the mounting cavity 226, and the end of the lead screw 40 near the fixing component 20 extends into the slide groove 223 and is correspondingly disposed with the fixing component 20. The mounting cavity 226 communicates with the slide groove 223, and the reset member 42 is disposed in the slide groove 223.

[0072] In this embodiment, the display component 22 is provided with a mounting cavity 226, which communicates with the slide groove 223. The mounting cavity 226 is provided with an internal thread 227, and correspondingly, the lead screw 40 is provided with an external thread 402. The lead screw 40 passes through the mounting cavity 226, so that the internal thread 227 and the external thread 402 are threadedly connected. Both ends of the lead screw 40 protrude from the mounting cavity 226, and one end extending into the slide groove 223 is correspondingly provided with the fixed component 20. In this way, by rotating the lead screw 40, the display component 22 can be driven to move relative to the fixed component 20, so that the movement of the display component 22 relative to the fixed component 20 is relatively stable.

[0073] The two ends of the lead screw 40 protrude from the mounting cavity 226, so that the user can operate one end of the lead screw 40 to move the display component 22 relative to the fixed component 20.

[0074] Furthermore, when the user rotates the lead screw 40 in the first direction, one end of the lead screw 40 extending into the slide groove 223 presses against the protrusion 204 in the direction of the reset member 42, thereby causing the display component 22 to slide relative to the fixed component 20, so that the end of the display component 22 in contact with the reset member 42 presses against the reset member 42 in a direction closer to the reset member 42. When the user rotates the lead screw 40 in the second direction, one end of the lead screw 40 extending into the slide groove 223 moves away from the reset member 42, thereby driving the display component 22 to slide relative to the fixed component 20 under the action of the reset member 42, so that the end of the display component 22 in contact with the reset member 42 moves away from the reset member 42.

[0075] It is understandable that the first direction and the second direction are opposite; specifically, one of the first direction and the second direction is clockwise and the other is counterclockwise.

[0076] Furthermore, the lead screw 40 protrudes from the end of the mounting cavity 226, and a rotating part is provided at the end away from the protrusion 204. The rotating part is provided with a plurality of strip-shaped protrusions to increase friction when the user rotates the lead screw 40.

[0077] According to one embodiment of this application, the display component 22 further includes a mounting groove 224 that communicates with a slide 223, and the protrusion 204 has a wire hole 206; the wearable device further includes a wire structure 3 that extends into the mounting groove 224 through the wire hole 206 and the slide 223.

[0078] In this embodiment, the display component 22 further includes a mounting groove 224, which is connected to a sliding groove 223. A wire hole 206 is provided on the protrusion 204. The wire structure 3 passes through the wire hole 206 and the sliding groove 223 and extends into the mounting groove 224, which facilitates the wiring of the wire structure 3.

[0079] Specifically, the display component 22 is electrically connected to the fixing component 20 via the wire structure 3, or the wearable device may also include a clamping component, the clamping part 1 is connected to the fixing component 20 via the strap 6, and the display component 22 is electrically connected to the clamping component via the wire structure 3.

[0080] Furthermore, the fixing component 20 and / or the clamping part 1 are equipped with electronic components, such as circuit boards, power supply devices, etc.

[0081] like Figure 6 and Figure 8As shown, in a specific application, the display component 22 is provided with a mounting groove 224. The display component 22 includes a stop portion 222, which is disposed within the mounting groove 224. A sliding groove 223 is provided within the stop portion 222. A wire hole 206 is provided on the protrusion 204, and a through hole 225 is provided on the stop portion 222. The mounting groove 224 communicates with the sliding groove 223 through the through hole 225. The wire hole 206 and the through hole 225 are correspondingly provided, thereby facilitating the passage of the wire structure 3.

[0082] Furthermore, along the sliding direction of the groove 223 and the protrusion 204, the wire hole 206 and the through hole 225 are elongated, so that the wire structure 3 does not need to move with the sliding of the groove 223 and the protrusion 204, thereby avoiding wear of the wire structure 3 during movement and improving the service life of the wire structure 3.

[0083] Furthermore, the fixing component 20 is provided with a wire-passing part, which communicates with the wire hole 206, and the wire structure 3 extends to the clamping part 1 through the wire-passing part.

[0084] In specific applications, the clamping part 1 is provided with a power supply device and / or a control device, which is electrically connected to the display component 22 through the wire structure 3.

[0085] According to one embodiment of this application, the two displays 220 can move relative to each other along the connecting line direction.

[0086] In this embodiment, the two displays 220 can move relative to each other along the connecting line, so that the user can adjust the displays 220 according to the actual distance between their eyes, so that the two displays 220 correspond to their eyes respectively, thereby improving eye comfort.

[0087] Furthermore, the two displays 220 are respectively a first display and a second display. The first display and the second display are respectively provided with a driving component 4. The driving component 4 includes a lead screw 40 and a reset component 42. The rotating part on the lead screw 40 on the first display and the rotating part on the lead screw 40 on the second display are both located on both sides of the display component 22 for easy user operation.

[0088] According to one embodiment of this application, the center of the display screen 220 is aligned with the center of the user's pupil by adjusting the lateral relative position.

[0089] Specifically, a protrusion 204 is provided on the fixing component 20, and a stop 222 is provided on the display component 22. The stop 222 includes a groove 223, and further, the groove 223 is a dovetail groove.

[0090] Furthermore, the lateral relative position of the fixing component 20 and the display component 22 is adjusted by means of a spring and a lead screw 40.

[0091] Specifically, the spring is a compression spring, the lead screw 40 has a knob part 44, the display component 22 is provided with a mounting cavity 226, and the mounting cavity 226 is provided with an internal thread 227, which corresponds to the internal thread 227 on the lead screw 40, so that the lead screw 40 has a self-locking function when no external force is applied.

[0092] When the knob 44 is rotated outward, the force of the spring causes the front and rear parts to move; when the knob 44 is rotated inward, the lead screw 40 pushes against the fixing component 20, and through the cooperation of the lead screw 40 and the internal thread 227 on the display component 22, the display component 22 and the fixing component 20 are moved.
