[0051] In head-mounted devices with a front island, the front island is positioned in front of the eyes after the user wears the device via a headband, allowing the user to view the image displayed on the front island without holding the display, thus freeing their hands. However, in these technologies, the position of the front island cannot be automatically adjusted, failing to adapt to the different eye positions of various users for a comfortable viewing distance.
[0052] Based on the above problems, the present invention proposes a head-mounted device 100, which aims to automatically adjust the position of the front island 20 to automatically adjust the comfortable distance according to the eye position of different users.
[0053] Please see Figures 1 to 5 In one embodiment of the present invention, the head-mounted device 100 includes a headband 10, a front island 20, and an adjustment mechanism 30; the front island 20 is located in front of the headband 10; the adjustment mechanism 30 includes a sliding connection portion 31 and a mounting portion 32, the sliding connection portion 31 is rotatably connected to the headband 10, and the mounting portion 32 is drivenly connected to the sliding connection portion 31, and the mounting portion 32 can drive the sliding connection portion 31 to slide relative to the mounting portion 32; the front island 20 is connected to the mounting portion 32; wherein, the direction of the rotation axis of the sliding connection portion 31 is defined as the first direction a, the relative sliding direction between the mounting portion 32 and the sliding connection portion 31 is defined as the second direction b, and the first direction a and the second direction b are set at an angle.
[0054] The technical solution of this invention uses an adjustment mechanism 30 to connect the headband 10 and the front island 20. The adjustment mechanism 30 includes a sliding connecting part 31 and a mounting part 32. The sliding connecting part 31 is rotatably connected to the headband 10, and the mounting part 32 is drivenly connected to the sliding connecting part 31. The front island 20 is connected to the mounting part 32. During use, the headband 100 can be worn on the user's head. By moving the front island 20 up and down, the sliding connecting part 31 rotates relative to the headband 10 about a first direction a, thereby achieving a 90-degree flip-fold of the front island 20. Additionally, the mounting part 32 can drive the sliding connecting part 31 to slide back and forth relative to the mounting part 32 along a second direction b, allowing the front island 20 to automatically adjust its position according to the user's eye position.
[0055] In this embodiment, the front island 20 can also be called a display device, which is a display tool used to display certain electronic documents on a screen through a specific transmission device and then reflect them to the human eye.
[0056] It should be noted that the mounting part 32 is driven to connect with the sliding connection part 31. The mounting part 32 can drive the sliding connection part 31 to slide relative to the mounting part 32. When the head-mounted device 100 is worn on the user's head, the sliding connection part 31 can be fixed in position relative to the headband 10 in the second direction b. At this time, under the drive of the mounting part 32, the mounting part 32 can move back and forth in the second direction b relative to the sliding connection part 31, so as to drive the front island 20 to move back and forth in the second direction b through the mounting part 32, thereby automatically adjusting the front and rear positions of the front island 20.
[0057] In practical applications, a depth sensor can be used to detect the distance between the front island 20 and the human eye, and the distance information can be used to control the sliding connection part 31 to slide relative to the mounting part 32, thereby achieving automatic adjustment of the front island 20's front and rear positions. Alternatively, a switch can be provided on the adjustment mechanism 30, and the user can trigger the switch to control the sliding connection part 31 to slide relative to the mounting part 32, thereby achieving automatic adjustment of the front island 20's front and rear positions.
[0058] Please see Figure 4 In one embodiment of the present invention, the sliding connection part 31 includes a fixed bracket 311 and a sliding component 312; the fixed bracket 311 is connected to the headband 10; the sliding component 312 is rotatably connected to the fixed bracket 311; and the mounting part 32 is drivenly connected to the sliding component 312.
[0059] With this configuration, the headband 10 can be fixedly connected to the fixed bracket 311, thereby fixing the adjustment mechanism 30 and the front island 20 together on the headband 10. In addition, by rotating the sliding component 312 to the fixed bracket 311, when the front island 20 is moved up and down, the sliding component 312 can be rotated relative to the fixed bracket 311 and the headband 10 about the rotation axis along the first direction a, thereby realizing the 90-degree flip-folding of the front island 20.
[0060] In practical applications, the fixing bracket 311 can be fixedly connected to the headband 10 by means of plug-in, screw connection, snap-fit, etc. In some embodiments, in order to facilitate the disassembly and assembly of the adjustment mechanism 30 and the headband 10, a snap-fit groove can be provided on the front side of the headband 10 so that the fixing bracket 311 is at least partially inserted into the snap-fit groove, so that the fixing bracket 311 and the snap-fit groove can be detachably connected.
[0061] Furthermore, the shape of the fixing bracket 311 can be, but is not limited to, plate-shaped, strip-shaped, frame-shaped, block-shaped, etc., as long as it can be connected to the headband 10.
[0062] Please see Figure 4 , Figure 5 In one embodiment of the present invention, the mounting part 32 includes a base 321 and a driving member 322; the front island 20 is connected to the base 321; the driving member 322 is disposed on the base 321 and is connected to the sliding component 312 in a transmission manner to drive the sliding component 312 to slide relative to the base 321.
[0063] With this configuration, when the front island 20 needs to be adjusted, the drive unit 322 operates to drive the sliding component 312 to slide relative to the base 321. Since the sliding component 312 and the headband 10 are relatively fixed in the front-back direction (second direction b), the base 321 slides relative to the sliding component 312 in the second direction b, thereby smoothly driving the front island 20 connected to the base 321 to move back and forth in the second direction b, so as to realize the automatic adjustment of the front island 20's front-back position.
[0064] In practical applications, the driving component 322 can be a motor 3221, which directly drives the sliding component 312 to slide relative to the base 321; or, the driving component 322 can be a structure in which the motor 3221 cooperates with the lead screw 3222, so that the motor 3221 drives the lead screw 3222 to rotate, and the rotation of the lead screw 3222 can drive the sliding component 312 to slide relative to the base 321; or, the driving component 3222 can also be a structure in which the motor 3221 cooperates with the gear and rack, so that the motor 3221 drives the gear to rotate, and the rotation of the gear drives the rack to move, and then the rack drives the sliding component 312 to slide relative to the base 321; of course, the driving component 322 can also be other driving methods, as long as it can smoothly drive the sliding component 312 to slide relative to the base 321, and no specific limitation is made here.
[0065] In some embodiments, in order to improve the overall aesthetics of the adjustment mechanism 30, a front baffle 323 can be provided on the front side of the base 321 and a rear baffle 324 can be provided on the rear side of the base 321, which can prevent the drive component 322 on the base 321 from being exposed and affecting the aesthetics.
[0066] Please see Figures 5 to 10 In one embodiment of the present invention, the sliding assembly 312 includes a sliding plate structure 3121 and a slider 3122; the sliding plate structure 3121 is rotatably connected to the fixed bracket 311 and is disposed opposite to the base 321; the side of the sliding plate structure 3121 facing the base 321 is provided with two limiting push blocks 3121c distributed at intervals along the second direction b; the slider 3122 is at least partially located between the two limiting push blocks 3121c and is drively connected to the driving member 322, which drives the slider 3122 to slide relative to the base 321.
[0067] With this setup, when the front island 20 needs to be adjusted, the drive unit 322 works to drive the slider 3122 to slide relative to the base 321. When the slider 3122 slides to abut against one of the limit push blocks 3121c, it will push the sliding plate structure 3121 to slide relative to the base 321 through the limit push block 3121c, thereby smoothly driving the entire sliding assembly 312 to slide relative to the base 321.
[0068] For example, when the position of the front island 20 needs to be adjusted forward, the drive component 322 drives the slider 3122 to slide backward relative to the base 321. When the slider 3122 slides to abut against the limiting push block 3121c near the headband 10, the limiting push block 3121c will push the sliding plate structure 3121 to slide backward relative to the base 321, so as to smoothly drive the entire sliding assembly 312 to slide backward relative to the base 321. Since the sliding assembly 312 and the headband 10 are relatively fixed in the front-back direction (second direction b), the base 321 slides forward relative to the sliding assembly 312, which can drive the front island 20 connected to the base 321 to slide forward. When the position of the front island 20 needs to be adjusted backward, the drive component 322 drives the slider 3122 to slide forward relative to the base 321. When the slider 3122 slides to abut against the limiting push block 3121c away from the headband 10, the limiting push block 3121c will push the sliding plate structure 3121 to slide forward relative to the base 321, so as to smoothly drive the entire sliding assembly 312 to slide forward relative to the base 321. Since the sliding assembly 312 and the headband 10 are relatively fixed in the front-back direction (second direction b), the base 321 slides backward relative to the sliding assembly 312, which can drive the front island 20 connected to the base 321 to slide backward.
[0069] Please see Figure 4 , Figures 6 to 10 In one embodiment of the present invention, the sliding plate structure 3121 includes a sliding plate 3121a and a first baffle 3121b; the sliding plate 3121a is rotatably connected to the fixed bracket 311 and is provided with a mounting hole c; the first baffle 3121b is installed in the mounting hole c and is disposed opposite to the base 321, and the limiting push block 3121c is disposed on the side of the first baffle 3121b facing the base 321.
[0070] This design, by splitting the sliding plate structure 3121 into a sliding plate 3121a and a first baffle 3121b, allows the first baffle 3121b to be installed at the mounting hole c of the sliding plate 3121a. In case of a malfunction requiring maintenance, the first baffle 3121b can be removed from the sliding plate 3121a to expose the position of the mounting hole c. Maintenance personnel can then maintain or replace structures such as the slider 3122 and the drive component 322 through the mounting hole c without having to disassemble the entire sliding plate structure 3121 or the adjustment mechanism 30, thus simplifying maintenance time and reducing costs.
[0071] In practical applications, the first baffle 3121b can be connected to the sliding plate structure 3121 by means of screw connection, snap-fit, etc., so that the first baffle 3121b covers the mounting hole c.
[0072] Furthermore, the limiting push plate 3122a and the first baffle 3121b can be integrally formed, or they can be connected together by means of bonding, screws, etc.
[0073] Please see Figure 10 In one embodiment of the present invention, the sliding plate 3121a is provided with a slide rail 312a extending along the second direction b, and the base 321 is provided with a sliding groove 321a extending along the second direction b. The slide rail 312a and the sliding groove 321a are slidably engaged.
[0074] With this configuration, the sliding rail 312a and the sliding groove 321a can guide and limit the sliding plate 3121a when it slides relative to the base 321, thereby improving the stability of the sliding component 312 sliding relative to the base 321 in the second direction b.
[0075] In some embodiments, sliding grooves 321a may be provided on both sides of the driving member 322, and sliding rails 312a may be provided on both opposite sides of the sliding plate 3121a, so that the two sliding rails 312a slide in cooperation with the two sliding grooves 321a respectively.
[0076] Please see Figure 4 In one embodiment of the present invention, the sliding plate 3121a is rotatably connected to the fixed bracket 311 via a damping shaft 313, which extends along the first direction a.
[0077] With this configuration, the sliding plate 3121a and the fixed bracket 311 are rotated by using a damping shaft 313. During rotation, the sliding plate 3121a can be stably stopped at a specified position by the damping action of the damping shaft 313, thereby stably stopping the front island 20 at a specified position. There is no need to design additional limiting components to stop the front island 20 at a specified position, which simplifies the structural design.
[0078] In some embodiments, two first mounting sleeves spaced apart along the first direction a can be provided on one side of the fixed bracket 311. The first mounting sleeves have first connecting holes extending along the first direction a. A second mounting sleeve is provided on one side of the sliding plate 3121a. The second mounting sleeve has second connecting holes extending along the first direction a. The second mounting sleeve is inserted between the two first mounting sleeves so that the two ends of the second connecting hole communicate with the two first connecting holes respectively. In addition, two damping shafts 313 can be provided. One end of one damping shaft 313 passes through one of the first connecting holes and is inserted into the second connecting hole. The other end of the other damping shaft 313 passes through the other first connecting hole and is inserted into the second connecting hole. Thus, the sliding plate 3121a and the fixed bracket 311 can be rotatably connected together by two damping shafts 313.
[0079] Please see Figures 4 to 7 In one embodiment of the present invention, the base 321 has a plurality of teeth 321b spaced apart along the second direction b on the side facing the first baffle 3121b, and a groove 321c is formed between two adjacent teeth 321b; the first baffle 3121b has a limiting elastic member 3 on the side facing the base 321, and the two ends of the limiting elastic member 3 are respectively limited and engaged with two of the grooves 321c; there is a return gap d between the slider 3122 and the limiting push block 3121c, and a push plate 3122a is provided at one end of the slider 3122. When the driving member 322 drives the slider 3122 to slide relative to the base 321, the push plate 3122a drives one end of the limiting elastic member 3 to pop out from the corresponding groove 321c.
[0080] With this configuration, when the driving component 322 drives the slider 3122 to slide forward, the slider 3122 first slides a short distance in the return gap d. During this process, the push plate 3122a on the slider 3122 pushes up the end of the limiting elastic member 3 away from the headband 10, so that it pops out from the corresponding slot 321c, thereby realizing the unlocking function. When the slider 3122 continues to slide forward until it abuts against a limiting push block 3121c away from the headband 10, the slider 3122 will push the sliding assembly 312 to slide forward as a whole. Since the sliding assembly 312 and the headband 10 are in the front-back direction... (Second direction b) is relatively fixed, so the base 321 slides backward relative to the sliding component 312, which can drive the front island 20 connected to the base 321 to slide backward. After sliding to the designated position, the slider 3122 can be driven by the drive component 322 or manually to slide backward a small distance within the return gap d, so that the push plate 3122a on the slider 3122 releases the pushing force on the end of the limiting elastic member 3 away from the headband 10, so that the end of the limiting elastic member 3 away from the headband 10 automatically resets under the action of the elastic force and falls into the corresponding slot 321c to achieve the self-locking function.
[0081] Similarly, when the driving component 322 drives the slider 3122 to slide backward, the slider 3122 first slides a short distance in the return gap d. During this process, the push plate 3122a on the slider 3122 pushes up the end of the limiting elastic member 3 near the headband 10 so that it pops out from the corresponding slot 321c, thereby realizing the unlocking function. When the slider 3122 continues to slide backward until it abuts against a limiting push block 3121c near the headband 10, the slider 3122 will push the sliding component 312 to slide backward as a whole. Since the sliding component 312 and the headband 10 are in the front-back direction (Second direction b) is relatively fixed, so the base 321 slides forward relative to the sliding component 312, which can drive the front island 20 connected to the base 321 to slide forward. After sliding to the designated position, the slider 3122 can be driven forward a short distance within the return gap d by the drive component 322 or manually, so that the push plate 3122a on the slider 3122 releases the pushing force on the end of the limiting elastic member 3 near the headband 10, so that the end of the limiting elastic member 3 near the headband 10 automatically resets under the action of the elastic force and falls into the corresponding slot 321c to achieve the self-locking function.
[0082] Therefore, this solution, in cooperation with the locking tooth 321b and the limiting elastic element 3, can achieve automatic unlocking and self-locking functions, and can also achieve bidirectional self-locking function.
[0083] In practical applications, the limiting elastic element 3 may include, but is not limited to, elastic structural elements such as sheet springs or springs.
[0084] Please see Figure 6 , Figure 7 In one embodiment of the present invention, the limiting elastic member 3 includes a connecting section 3a and two limiting sections 3b; the connecting section 3a is connected to the first baffle 3121b; the two limiting sections 3b are respectively connected to the opposite ends of the connecting section 3a, the limiting sections 3b are set at an angle to the connecting section 3a, and the end of the limiting section 3b away from the connecting section 3a is limited and engaged with the slot 321c.
[0085] With this configuration, the limiting elastic element 3 can be installed and fixed as a whole on the first baffle 3121b via the connecting section 3a. Then, the ends of the two limiting sections 3b away from the connecting section 3a are respectively limited and engaged with two of the slots 321c. During the process of the driving member 322 driving the slider 3122 to slide back and forth, the push block on the slider 3122 can lift one end of the limiting section 3b, so that the end of the limiting section 3b pops out from the corresponding slot 321c, thereby realizing the unlocking function. When the push block on the slider 3122 releases the pushing force on the limiting section 3b, the end of the limiting section 3b will automatically reset under the action of the elastic force and fall into the corresponding slot 321c, thereby realizing the self-locking function.
[0086] In some embodiments, in order to simplify the manufacturing process, the connecting segment 3a and the two limiting segments 3b can be designed as an integrally formed structure. During the manufacturing process, the two ends of a whole piece of spring sheet can be bent to form the connecting segment 3a and the two limiting segments 3b.
[0087] Please see Figure 7 In one embodiment of the present invention, the slot 321c has a first side 32a and a second side 32b opposite to each other. The first side 32a is set at an acute angle to the second direction b, and the second side 32b is set at a right angle to the second direction b. The limiting segment 3b includes an inclined plate 3b1 and a limiting plate 3b2. One end of the inclined plate 3b1 is connected to the connecting segment 3a, and the limiting plate 3b2 is connected to the end of the inclined plate 3b1 away from the connecting segment 3a. The inclined plate 3b1 is provided with a first limiting surface 3b11 facing away from the limiting plate 3b2, and the first limiting surface 3b11 is parallel to the first side 32a. The limiting plate 3b2 is provided with a second limiting surface 3b21 facing away from the inclined plate 3b1, and the second limiting surface 3b21 is parallel to the second side 32b.
[0088] With this configuration, in the second direction b, by designing the first side 32a of the slot 321c as an inclined surface and the second side 32b of the slot 321c as a right-angled surface, the first limiting surface 3b11 of the inclined plate 3b1 cooperates with the first side 32a, and the second limiting surface 3b21 of the limiting plate 3b2 cooperates with the second side 32b, making it easier to limit the elastic member 3. When the end of one of the limiting segments 3b pops out of the corresponding slot 321c, since the end of the other limiting segment 3b and the tooth shape of the corresponding slot 321c are aligned, that is, the first limiting surface 3b11 and the first side 32a of the end of the other limiting segment 3b are aligned inclined surfaces, the slot 321c will not block the end of the other limiting segment 3b. Therefore, the slider 3122 can smoothly push the limiting push plate 3122a forward or backward. After the end of the limiting segment 3b automatically resets and falls into the corresponding slot 321c, it can achieve automatic self-locking under the right-angle limiting action of the second limiting surface 3b21 and the second side surface 32b.
[0089] Please see Figure 1 , Figure 2 In one embodiment of the present invention, a depth sensor (not shown) may be provided on the side of the front island 20 near the headband 10. The depth sensor is used to detect the distance of the human eye.
[0090] With this setup, the distance between the front island 20 and the human eye is obtained by using a depth sensor to detect the distance in real time. The distance information is then used to control the distance by which the sliding connection 31 slides relative to the mounting part 32, thereby enabling more precise real-time adjustment of the front island 20's position.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
