Description

Technical Field

[0001] This application belongs to the field of smart wearable device technology, specifically relating to a head-mounted wearable device. Background Technology

[0002] Smart glasses typically refer to mixed reality glasses (MR glasses), augmented reality glasses (AR glasses), and virtual reality glasses (VR glasses). Smart glasses can be considered a type of head-mounted wearable device that uses computer technology to integrate real-world and virtual-world information, providing users with a completely new experience. In these technologies, the position of the head-mounted wearable device on the user's head can only be adjusted during wear. Once worn, the orientation of the display screen is fixed, and the user cannot adjust the screen's orientation in real time during subsequent use. This can lead to the display screen not being aligned with the eyes, reducing user eye comfort. Summary of the Invention

[0003] The purpose of this application is to disclose a head-mounted wearable device that can solve the problem described in the background art of difficulty in adjusting the orientation of the display screen after the head-mounted wearable device is fixedly worn on the user's head.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, this application discloses a head-mounted wearable device, which includes a device body, a connecting strap, a first base, a second base, and an adjustment part. The device body includes a display screen. The adjustment part is connected to the device body via the connecting strap. The adjustment part is movably connected to the first base. The device body is movably connected to the second base. The first base, the second base, and the connecting strap form a wearing space. When the adjustment part moves relative to the first base, the adjustment part drives the display screen to move relative to the second base via the connecting strap to adjust the orientation of the display screen.

[0006] The technical solution adopted in this application can achieve the following beneficial effects:

[0007] The head-mounted wearable device disclosed in this application improves the structure of related head-mounted wearable devices. The adjustment unit is connected to the main body of the device via a connecting strap, and is movably connected to a first base. The main body of the device is movably connected to a second base. This allows the user to adjust the relative position between the display screen and their eyes by moving the adjustment unit relative to the first base. This, in turn, causes the connecting strap to rotate the display screen relative to the second base, thus changing the angle of the display screen relative to the user's eyes. In other words, this application achieves orientation adjustment of the display screen through partial adjustment of the adjustment unit, thereby enabling posture adjustment of the display screen, increasing the freedom of display screen adjustment, and improving the user experience. This application solves the problem described in the background art where adjusting the posture of the display screen after the head-mounted wearable device is fixedly worn on the user's head is a cumbersome process.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The wearable headband device disclosed in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0024] like Figures 1 to 6 As shown in the figure, this application discloses a head-mounted wearable device, which includes a device body 100, a connecting strap 200, a first base 300, a second base 400, and an adjustment part 500.

[0025] The main body 100 serves as the foundation for the connecting strap 200, the first base 300, the second base 400, and the adjustment unit 500. The connecting strap 200 is primarily used to secure the head-mounted wearable device to the user's head, facilitating its use.

[0026] The main body 100 includes a display screen 110. An adjustment unit 500 is connected to the main body 100 via a connecting strap 200. The adjustment unit 500 is movably connected to a first base 300, and the main body 100 is movably connected to a second base 400. The first base 300, the second base 400, and the connecting strap 200 form a wearing space 600. When the adjustment unit 500 moves relative to the first base 300, the adjustment unit 500 drives the display screen 110 to move relative to the second base 400 via the connecting strap 200, thereby adjusting the orientation of the display screen 110. Adjusting the orientation of the display screen 110 is equivalent to adjusting the rotation angle of the display screen 110 relative to the user's eyes.

[0027] In other words, in this application, after the user wears the head-mounted device, when the user wants to adjust the relative position between the display screen 100 and their eyes, they can operate the adjustment unit 500. This causes the adjustment unit 500 to move relative to the first base 300, thereby moving the connecting strap 200. The moving connecting strap 200 then causes the main body 100 to move relative to the second base 400, causing the display screen 110 to rotate along with the movement of the main body 100. This changes the relative position between the display screen 110 and the user's eyes. Normally, it is comfortable for the user to look at the display screen 110 at a downward angle of 5°. Of course, the specific position between the display screen 110 and the user's eyes can be adjusted according to the user's own usage habits.

[0028] The head-mounted wearable device disclosed in this application improves the structure of related head-mounted wearable devices. The adjustment unit 500 is connected to the main body 100 via a connecting strap 200, and is movably connected to the first base 300, while the main body 100 is movably connected to the second base 400. This allows the user to adjust the relative position between the display screen 110 and their eyes by moving the adjustment unit 500 relative to the first base 300. This, in turn, causes the connecting strap 200 to rotate the display screen 110 relative to the second base 400, thereby changing the angle of the display screen 110 relative to the user's eyes. In other words, this application achieves orientation adjustment of the display screen 110 through partial adjustment of the adjustment unit 500, simplifying the process of adjusting the display screen 110's posture.

[0029] In the head-mounted wearable device disclosed in this application embodiment, one of the first base 300 and the adjustment part 500 may have multiple positioning grooves 310, and the other of the first base 300 and the adjustment part 500 may have a positioning protrusion 510. The first base 300 and the adjustment part 500 are positioned and engaged with the positioning protrusion 510 through one of the multiple positioning grooves 310. In this case, the positioning protrusion 510 can be positioned and engaged with the multiple positioning grooves 310 respectively, so that the first base 300 and the adjustment part 500 can achieve multiple fixed relative positional relationships through the positioning engagement of the positioning grooves 310 and the positioning protrusion 510. This is beneficial for driving the display screen 110 to rotate at multiple angles through the connecting strap 200, that is, it is beneficial for expanding the adjustment range of the orientation of the display screen 110.

[0030] In a further technical solution, two adjacent positioning grooves 310 can be connected to form a groove with wavy edges on both sides, and the positioning protrusion 510 slides in engagement with the groove. In this case, the connection between the two adjacent positioning grooves 310 reduces the adjustable distance each time, thereby improving the adjustment accuracy of the adjustment part 500 each time, and thus making the adjustment accuracy of the rotation angle of the display screen 110 higher. Furthermore, the sliding engagement between the positioning protrusion 510 and the groove helps reduce adjustment resistance and improves the convenience of user adjustment.

[0031] In the head-mounted wearable device disclosed in this application embodiment, the first base 300 may have multiple positioning grooves 310, and the adjustment part 500 may include a positioning protrusion 510, an elastic element 520, and an operating body 530. The two ends of the elastic element 520 are respectively connected to the positioning protrusion 510 and the operating body 530. The elastic element 520 has an adjustment state and a limiting state, wherein: in the adjustment state, the elastic element 520 is compressed, and the operating body 530 drives the positioning protrusion 510 to slide and engage with the multiple positioning grooves 310 through the elastic element 520; in the limiting state, the elastic element 520 is extended so that the positioning protrusion 510 is positioned and engaged with one positioning groove 310.

[0032] In the above-described situation, during the adjustment of the adjustment unit 500, the user can operate the entire adjustment unit 500 through the operating body 530. Specifically, during the adjustment process, the positioning protrusion 510 compresses the elastic member 520, creating a space for relative movement between the positioning protrusion 510 and the positioning groove 310, allowing the positioning protrusion 510 and the multiple positioning grooves 310 to slide together. When adjusted to the desired position, the positioning protrusion 510 and the positioning groove 310 achieve a positioning engagement. At this time, insufficient force is applied to the elastic member 520, allowing the elastic member 520 to be in an extended state. Since the extended elastic member 520 has an elastic force, this elastic force is applied to the positioning protrusion 510, thereby restricting the specific position where the positioning protrusion 510 and the positioning groove 310 achieve a positioning engagement. This improves the stability of the positioning engagement between the positioning protrusion 510 and the positioning groove 310, ensuring a more stable relative position between the display screen 110 and the user's eyes after adjustment. The elastic element 520 can be a structure that can stretch and deform, such as a spring or a rubber strip. This application does not limit the specific form of the elastic element 520.

[0033] During the movement of the adjustment part 500 relative to the first base 300, the adjustment part 500 and the first base 300 may separate. If they separate, the rotation adjustment of the display screen 110 will fail. To avoid the failure of the rotation adjustment of the display screen 110, in a further technical solution, the first base 300 may also include a limiting protrusion 320, and the operating body 530 may also have a limiting groove 531. The limiting protrusion 320 has multiple positioning grooves 310. The positioning protrusion 510 and the elastic member 520 are both located in the limiting groove 531. One end of the elastic member 520 is connected to the bottom wall of the limiting groove 531. The limiting protrusion 320 and the limiting groove 531 are guided and engaged in the direction of the arrangement of the multiple positioning grooves 310, and are engaged in the direction perpendicular to the movement of the adjustment part 500 relative to the first base 300.

[0034] In the above situation, the guiding engagement direction between the limiting protrusion 320 and the limiting groove 531 is consistent with the direction of movement of the adjusting part 500 relative to the first base 300, which facilitates the user's movement of the adjusting part 500 relative to the first base 300. At the same time, the engagement of the limiting protrusion 320 and the limiting groove 531 in a direction perpendicular to the direction of movement of the adjusting part 500 relative to the first base 300 can prevent the adjusting part 500 from separating from the first base 300, thereby ensuring the effectiveness of adjusting the rotation angle of the display screen 110 by adjusting the adjusting part 500.

[0035] The above technical solution places the positioning protrusion 510 and the positioning groove 310 between the limiting protrusion 320 and the limiting groove 531, thereby enabling the adjusting part 500 and the first base 300 to achieve positioning and engagement at the same position. Of course, the positioning and engagement between the adjusting part 500 and the first base 300 can be set separately. In another optional technical solution, one of the first base 300 and the adjusting part 500 can have a limiting protrusion 320, and the other of the first base 300 and the adjusting part 500 can have a limiting groove 531. In the direction perpendicular to the movement of the adjusting part 500 relative to the first base 300, the first base 300 and the adjusting part 500 are engaged through the limiting protrusion 320 and the limiting groove 531. In this case, the engagement between the limiting protrusion 320 and the limiting groove 531 in a direction perpendicular to the movement of the adjusting part 500 relative to the first base 300 prevents separation between the adjusting part 500 and the first base 300, thus ensuring the effectiveness of the final rotation adjustment of the display screen 110. Furthermore, the separate positioning and engagement between the adjusting part 500 and the first base 300 also prevents interference between the positioning and engagement.

[0036] In this application, the types of limiting protrusions 320 and limiting grooves 531 that enable engagement in the direction perpendicular to the movement of the adjusting part 500 relative to the first base 300 are varied. Optionally, the limiting groove 531 can be a dovetail groove, and the limiting protrusion 320 can be a dovetail protrusion adapted to the dovetail groove. Alternatively, the limiting groove 531 can be a T-groove, and the limiting protrusion 320 can be a T-shaped protrusion adapted to the T-groove. This application does not limit the specific shape of the limiting protrusion 320 and the limiting groove 531.

[0037] In the head-mounted wearable device disclosed in this application, the adjustment part 500 is movable relative to the first base 300, and the device body 100 is movable relative to the second base 400. To enable the first base 300 and the second base 400 to adapt well to the rotation of the adjustment part 500 and the device body 100 respectively, optionally, at least one of the first base 300 and the second base 400 can be a flexible member. In this case, when the adjustment part 500 rotates relative to the first base 300, and when the device body 100 rotates relative to the second base 400, the flexible first base 300 and the second base 400 can adaptively deform, thereby adapting to the rotation of the adjustment part 500 and the second base 400. Since the first base 300 and the second base 400 have undergone adaptive deformation at the connection points with the adjustment part 500 and the main body 100 of the device, respectively, the first base 300 and the second base 400 do not need to be displaced at the connection point with the user's head, which helps to improve the stability and comfort of the user's wearing.

[0038] In the head-mounted wearable device disclosed in this application, the connecting strap 200 can be a rigid connecting strap. Compared to a flexible connecting strap, a rigid connecting strap is advantageous for enabling the adjustment unit 500 to move in tandem with the device body 100 via the connecting strap 200. Rigid connecting straps can be of various types; specifically, they can be made of plastic or metal with moderate hardness. This application does not limit the specific materials used for the rigid connecting strap.

[0039] In the head-mounted wearable device disclosed in this application embodiment, the adjustment part 500 may further include a first arcuate surface 540, and the first base 300 may further include a second arcuate surface 330. The concave surfaces of both the first arcuate surface 540 and the second arcuate surface 330 face the device body 100, and the adjustment part 500 and the first base 300 are slidably engaged through the first arcuate surface 540 and the second arcuate surface 330. In this case, the curvature of the first arcuate surface 540 and the second arcuate surface 330 matches each other, which facilitates the user to quickly slide the adjustment part 500 relative to the first base 300 through the engagement between the first arcuate surface 540 and the second arcuate surface 330.
