All other embodiments, based on the embodiments herein, which are within the scope of the protection of the present application, will be within the skill of the art without inventive effort. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application. In this application, unless otherwise indicated, terms of orientation such as "upper", "lower", "left" and "right" are generally used to refer to the directions of the drawings in which the device is actually used or in an operating state.
The present application provides a head-mounted device, which is described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.
Referring to fig. 1, the present application provides a head-mounted device, which may be a head-mounted display device (such as VR glasses and AR glasses), or may be a head-mounted device such as a head lamp. The head mounted display device is described as an example in this application.
Referring to fig. 1, the head-mounted device includes a display portion 100, an arc-shaped housing 300, and at least two headbands 200, wherein the display portion 100 is disposed opposite to the arc-shaped housing 300, and the display portion 100 can be attached to the face of a user, and the arc-shaped housing 300 can be attached to the back of the brain of the user. One end of each of the head bands 200 is fixed to the display part 100 and the other end thereof is inserted into the inside of the arc-shaped case 300, so that the display part 100, the arc-shaped case 300 and the head bands 200 may form a surrounding space for adapting to the head of the user.
Referring to fig. 2 and 3, a plurality of limiting posts 120 are disposed at the end of the display portion 100, a limiting hole 230 is disposed at one end of the headband 200, and the limiting posts 120 are inserted into the limiting hole 230 to limit the relative positions of the headband 200 and the display portion 100 in degrees of freedom, such as front, rear, left, right, etc. The end of the limiting post 120 is provided with a limiting block 121, and the limiting block 121 can be pressed to the edge of the headband 200 at the limiting hole 230, so as to limit the freedom degrees of the headband 200 and the display part 100 in the inner and outer directions, and prevent the headband 200 from being separated from the display part 100.
Referring to fig. 2 and 3, an end portion of the headband 200 is connected to a damping member 220, a latch 240 is disposed at the end portion of the headband 200, and a locking slot 221 is correspondingly disposed on the damping member 220, and the latch 240 can be inserted through the locking slot 221, so that the damping member 220 and the headband 200 are relatively fixed. The end of the display part 100 is concaved inward to form a fixing groove 110, and a fixing cover 130 is detachably disposed above the fixing groove 110. The end of the headband 200 is inserted into the fixing groove 110 while the damping member 220 is placed in the fixing groove 110, preventing the headband 200 from being separated from the fixing groove 110 of the display part 100.
When the fixing cover 130 is fixed to the display part 100 above the fixing groove 110, the fixing cover 130 abuts against the end surface of the damping member 220, so that the fixing cover 130 and the damping member 220 have a certain friction force, thereby enabling the display part 100 to maintain a relative position with respect to the headband 200 using the friction force. When the position of the display part 100 needs to be adjusted according to facial features such as the nose bridge of the user, a torsion force is applied to the display part 100, so that the fixed cover 130 rotates relative to the damping member 220, and the display part 100 rotates relative to the headband 200 by an angle, so that the user's face is more fitted, and wearing comfort is improved.
The engagement of the stopper posts 120 with the stopper holes 230 can limit the multidirectional degrees of freedom of the display unit 100 and the headband 200, and can limit the rotation center of the display unit 100 when the display unit 100 rotates relative to the headband 200, thereby maintaining the accuracy of the relative positions of the display unit 100 and the headband 200. Since the fixing cover 130 and the damping member 220 have a certain friction force, the position of the display part 100 with respect to the headband 200 can be adjusted according to the user's requirement, and the adjusted relative position of the display part 100 and the headband 200 can be maintained.
Referring to fig. 2-4, in another embodiment, a stopper 131 is disposed in the fixing slot 110 or on the fixing cover 130, and the stopper 131 abuts against two sides of the latch 240, so that the relative positions of the display portion 100 and the headband 200 are fixed. In order to improve the matching degree of the head-mounted device and reduce the production cost, the stop block 131 is disposed on the fixed cover 130, and whether the display part 100 and the headband 200 of the head-mounted device are adjustable is adjusted by replacing different fixed covers 130.
Referring to fig. 1 and 2, the arc-shaped housing 300 has a hollow waist-shaped structure, and has a component for adjusting the relative positions of the two head bands 200, so that the head-mounted device can be adapted to users with different head circumferences. The arc-shaped housing 300 is assembled by a first housing 310 and a second housing 320. The portion that fits behind the user's brain is defined as a first housing 310 and the portion that is away from the user's brain is defined as a second housing 320. The first casing 310 and the second casing 320 are both thin-walled, so that an inner space of the arc-shaped casing 300 can be formed after the first casing 310 and the second casing 320 are assembled.
In the application, the first shell 310 and the second shell 320 can both adopt injection molding technology, so that the assembly of a plurality of parts in the arc-shaped shell 300 is facilitated, the assembly difficulty can be reduced, and the assembly efficiency is improved.
Referring to fig. 5 and 6, an annular wall 340 is disposed in the arc-shaped housing 300, and one end of the annular wall 340 is fixed to the interior of the second housing 320, and the other end extends toward the first housing 310. The annular wall 340 is provided with limiting gear teeth 341 on an inner side wall or an outer side wall, wherein the limiting gear teeth 341 are arranged along an axial direction of the annular wall 340 and are arranged along a circumferential direction of the annular wall 340.
Referring to fig. 5 and 7, the arc-shaped housing 300 is further provided with a locking gear 500, an adjusting gear 600, a fixing plate 700 and an elastic member 800, and since one end of each headband 200 includes a rack 210, the rack 210 is inserted into the arc-shaped housing 300, and two racks 210 of the two headband 200 are respectively engaged with two opposite sides of the adjusting gear 600. When the adjustment gear 600 rotates clockwise or counterclockwise, the two headband 200 can be driven to deviate from or approach each other by the force of the engagement of the adjustment gear 600 with the two racks 210, thereby adapting to users with different head circumferences.
Referring to fig. 5, a first through hole is formed in the middle of the locking gear 500, and the locking gear 500 is non-rotatably sleeved on the outside of a gear shaft 610, so that the gear shaft 610 is utilized to drive the adjusting gear 600 and the locking gear 500 to rotate synchronously. The locking gear 500 is movable in the axial direction of the gear shaft 610 such that at least a portion of the locking gear 500 can be engaged to the annular wall 340 and teeth of the locking gear 500 can be inter-engaged to the limiting teeth 341 of the annular wall 340. In this embodiment, the locking gear 500 may move in the axial direction by the pressure of the hand of the user, or may move in the axial direction by a driving member such as a linear motor.
Referring to fig. 5 to 7, when part or all of the locking gear 500 is engaged with the limiting gear teeth 341, a force exists between the locking gear 500 and the annular wall 340 of the arc-shaped housing 300, so that the locking gear 500 is fixed with respect to the arc-shaped housing 300. Since the locking gear 500 and the adjusting gear 600 are relatively fixed through the gear shaft 610, the adjusting gear 600 is restricted from rotating, so that the two racks 210 are relatively locked, and at this time, the headband 200 of the head-mounted device cannot be tightened and expanded, so that the head-mounted device can be stably worn on the head of the user.
When the locking gear 500 moves in the axial direction of the gear shaft 610, the locking gear 500 is gradually separated from the limiting gear teeth 341, and the force applied to the locking gear 500 by the annular wall 340 is removed, so that the locking gear 500 can be freely rotated. When the user controls the two head bands 200 to move toward or away from each other by both hands, the two racks 210 rotate the adjustment gear 600 through the engagement of the gear teeth. Since the locking gear 500 and the adjusting gear 600 are relatively fixed through the gear shaft 610, the locking gear 500 and the adjusting gear 600 can be moved in synchronization. The headband 200 of the head-mounted device can be freely tightened and expanded at this time, so that the relative positions of the two headbands 200 can be adjusted according to the circumference of the user.
Because the engagement distance between the locking gear 500 and the limiting gear teeth 341 of the annular wall 340 is smaller than or equal to the movement distance of the locking gear 500 along the axial direction of the gear shaft 610, in order to achieve the miniaturization design of the head-mounted device, the part of the locking gear 500 is engaged with the limiting gear teeth 341, so that the movement distance of the locking gear teeth can be effectively shortened, the thickness of the arc-shaped shell 300 is reduced, and the miniaturization and light-weight design of the head-mounted device are achieved.
Referring to fig. 5, a fixing plate 700 is disposed on the inner wall of the arc-shaped housing 300 by a buckle, a third through hole is disposed in the middle of the fixing plate 700, and the fixing plate 700 is sleeved outside the gear shaft 610, such that the fixing plate 700 is disposed between the adjusting gear 600 and the locking gear 500. The elastic member 800 is sleeved to the outside of the gear shaft 610, and one end of the elastic member 800 is abutted to the fixing plate 700 and the other end is abutted to the end face of the locking gear 500, and the elastic member 800 is preferably a coil spring in this embodiment.
Referring to fig. 5-7, when in the initial state, a portion of the locking gear 500 is engaged with the limiting gear teeth 341 of the annular wall 340, so that the locking gear 500 and the adjusting gear 600 are locked in the arc-shaped housing 300, thereby limiting the movement of the two racks 210 relative to the arc-shaped housing 300. When in the adjustment state, the locking gear 500 is driven to move in the axial direction of the gear shaft 610 such that the elastic member 800 provided between the locking gear 500 and the fixing plate 700 is continuously compressed until the locking gear 500 is completely separated from the limiting gear teeth 341 such that the locking gear 500 and the adjustment gear 600 can be freely rotated. The user may control the movement of the two headband 200 toward or away from each other by the fingers so that the head-mounted device may be adaptively adjusted according to the user's head circumference. After being adjusted to a proper position, the headset enters a reset state, and at this time, the pressure acting on the locking gear 500 gradually disappears, the elastic member 800 converts its own elastic force into a pushing force, and drives the locking gear 500 to move reversely along the axial direction of the gear shaft 610, so that the locking gear 500 gradually engages with the limiting gear teeth 341 of the annular wall 340. When the locking gear 500 moves to the initial position, the head-mounted device is restored to the initial state, at which time the locking gear 500 and the adjusting gear 600 are locked with respect to the inside of the arc-shaped housing 300, and at the same time, the two racks 210 after adjustment are locked with respect to the arc-shaped housing 300, so that the head-mounted device after adjustment is stably worn to the head of the user.
Referring to fig. 5 and 6, a second through hole 330 is formed in the sidewall of the arc-shaped housing 300, and a central axis of the second through hole 330 is collinear with a central axis of the gear shaft 610. The head-mounted device further includes a key 400, wherein the key 400 is slidably disposed in the second through hole 330, such that one end of the key 400 abuts against the end surface of the locking gear 500, and the other end of the key slightly protrudes from the surface of the second housing 320. The user applies pressure to one end of the pressing part, and drives the locking gear 500 to move along the axial direction of the gear shaft 610 by using the key 400, so that the user operation is facilitated, and the number and weight of components can be reduced as much as possible, thereby realizing the miniaturization and light weight design of the head-mounted device.
Referring to fig. 5 and 8, the key 400 is in a columnar structure, in this application, the end portion of the key 400 extending into the second through hole 330 is concaved to form a slot 430, and the end portion of the gear shaft 610 may partially extend into the slot 430, so that the arrangement of each component in the arc-shaped housing 300 is more compact, and the utilization rate of the internal space of the arc-shaped housing 300 is improved.
Referring to fig. 5 and 8, an avoiding distance is left between the bottom of the slot 430 and the end surface of the gear shaft 610, and the avoiding distance is greater than or equal to the moving distance of the locking gear 500, so that when the key 400 drives the locking gear 500 to move to disengage from the limiting gear 341, the end of the gear shaft 610 and the bottom of the slot 430 still keep a distance, thereby avoiding interference between the key 400 and the gear shaft 610.
Referring to fig. 5, the central axes of the key 400, the locking gear 500 and the adjusting gear 600 are arranged in line. When a force is applied to the button 400, the button 400 drives the locking gear 500 to move in the axial direction, and simultaneously adjusts the relative position of the headband 200, the rack 210 can drive the adjusting gear 600 to rotate in synchronization with the locking gear 500. Because the central axis of the key 400, the central axis of the locking gear 500 and the central axis of the adjusting gear 600 are collinear, the forces applied to the locking gear 500 and the adjusting gear 600 by the key 400 are uniformly distributed, so that the combination of bending moment and torque can be reduced, the performance requirements on the locking gear 500, the adjusting gear 600 and the gear shaft 610 are reduced, and the manufacturing cost can be reduced while the use performance is ensured.
In the present embodiment, the central axis of the key 400, the central axis of the locking gear 500 and the central axis of the adjusting gear 600 are co-linear compared to the prior art in which the force applied by the user is concentrated and distributed to a certain edge position of the key 400. On the one hand, the acting force distributed on the locking gear 500 and the adjusting gear 600 can be controlled to be uniform, and the bending moment generated by the acting force can be reduced or avoided as much as possible; on the other hand, since the elastic member 800 is sleeved outside the gear shaft 610 and between the locking gear 500 and the fixing plate 700, the force applied to the locking gear 500 can uniformly compress the elastic member 800, so that the elastic member 800 always moves along the axial direction of the gear shaft 610, and the deformation of the elastic member 800 is basically consistent, thereby ensuring that the locking gear 500 and the limiting gear teeth 341 can be accurately engaged after the elastic member 800 is reset, so that the headset has stable performance and higher control precision in long-term use.
Referring to fig. 5 and 6, a fixing rim 350 is further disposed in the arc-shaped housing 300, and one end of the fixing rim 350 is connected to the inner wall of the second housing 320, and the other end extends toward the first housing 310. The fixing rim 350 surrounds the outside of the second through hole 330 and is located inside the annular wall 340 such that the fixing rim 350 forms a locking space with the annular wall 340. The central axis of the fixed rim 350 is collinear with the central axis of the annular wall 340 such that the central axis of the locking space coincides with the central axis of the locking gear 500.
Referring to fig. 5 and 7, the inner side wall of the annular wall 340 is provided with the above-mentioned limiting gear teeth 341, the end face of the locking gear 500 facing the annular wall 340 is concave to form the clamping groove 520, when a portion of the locking gear 500 extends into the locking space, the gear teeth of the locking gear 500 are engaged with the limiting gear teeth 341, and the fixing surrounding edge 350 extends into the clamping groove 520. The annular wall 340 and the fixed surrounding edge 350 form a locking space for matching the locking gear 500, so that the position accuracy of the locking gear 500 when engaged with the limiting gear teeth 341 can be improved, and meanwhile, the fixed surrounding edge 350 extending into the clamping groove 520 can limit a limiting position of the locking gear 500 relative to the arc-shaped shell 300, so that the accuracy of the reset position of the locking gear 500 is ensured.
Referring to fig. 5, 6 and 8, the side wall of the key 400 is uniformly provided with a plurality of sliding blocks 410, the fixed surrounding edge 350 is correspondingly provided with a plurality of sliding grooves 351, and the sliding blocks 410 are correspondingly embedded into the sliding grooves 351. When the key 400 moves relative to the arc-shaped housing 300, the slider 410 may be synchronously embedded in the sliding groove 351 to move.
By utilizing the cooperation of the sliding block 410 and the sliding groove 351, the movement direction of the key 400 can be limited, and the movement precision is improved; meanwhile, the limit position of the key 400 during resetting can be limited, so that the key 400 is ensured to be embedded in the second through hole 330 all the time.
Referring to fig. 5 and 7, the end surface of the locking gear 500 is provided with at least one rib 510, the ribs 510 are distributed along the circumferential direction of the locking gear 500, and the ribs 510 are concentrically arranged. The heights of the plurality of ribs 510 in this embodiment are uniform, and the ribs 510 can abut against the surface of the key 400 when the key 400 drives the locking gear 500 to move along the axial direction of the gear shaft 610.
When the headset is in the adjustment state, the button 400 abuts against the locking gear 500 and applies a pushing force to the locking gear 500, and at the same time, the adjustment gear 600 drives the locking gear 500 to rotate through the gear shaft 610 and applies a torsion force to the locking gear 500, so that the locking gear 500 rotates relative to the button 400. The rib 510 can reduce the contact area between the key 400 and the locking gear 500, so as to reduce the sliding friction between the key 400 and the locking gear 500 in the adjustment state, thereby reducing the resistance of the locking gear 500 and the adjustment gear 600 in rotation, and making it easier for the user to push and pull the two headband 200.
Referring to fig. 6-8, the key 400 is inserted into the end surface of the second through hole 330 to form a weight-reducing slot 420, so as to reduce the weight of the key 400 and realize the lightweight design of the head-mounted device. In this embodiment, the weight-reducing groove 420 is formed as a ring along the circumferential direction of the key 400, and when the key 400 abuts against the end face of the locking gear 500, the rib 510 abuts against the outer edge and/or the vicinity of the inner edge of the weight-reducing groove 420.
Referring to fig. 5 and 7, a plurality of baffles 360 are disposed in the arc-shaped housing 300, the baffles 360 are connected to the inner walls of the first housing 310 and/or the second housing 320, and when one end of the headband 200 is inserted into the arc-shaped housing 300, the baffles 360 are attached to the upper side and/or the lower side of the rack 210. The baffle 360 is connected to the inner wall of the first housing 310 in this embodiment, and both the upper side and the lower side of the rack 210 are provided with the baffle 360.
The baffle 360 is attached to the upper side and the lower side of the rack 210, so that acting force can be applied to the rack 210, and deformation of the rack 210 due to gravity or other acting force can be reduced; at the same time, the moving direction of the rack 210 can be limited, and the meshing precision between the rack 210 and the adjusting gear 600 can be ensured.
Referring to fig. 6 and 7, a protrusion 311 is disposed on an inner wall of the first housing 310, and the protrusion 311 is disposed along a movement track of the rack 210; the inner wall of the second housing 320 is provided with a plurality of pressing plates 321, and the pressing plates 321 are disposed corresponding to the protrusions 311, such that the protrusions 311 are abutted to one surface of the rack 210, and the pressing plates 321 are abutted to the other opposite surface of the rack 210.
The protrusion 311 applies a bearing force to the rack 210, and the pressing plate 321 applies a pressing force to the rack 210, so that the position of the rack 210 in the arc-shaped housing 300 can be limited, and the rack 210 is prevented from swinging or shifting when engaged with the adjusting gear 600. By abutting the protrusions 311 and the pressing plate 321 to the two surfaces of the rack 210, the offset of the rack 210 during movement can be reduced, and the accuracy of the head-mounted device during adjustment can be improved.
Referring to fig. 5 and 7, the end of the rack 210 is provided with a protrusion 211, the direction of the protrusion 211 is perpendicular to the moving direction of the rack 210, and when the rack 210 is engaged with the adjusting gear 600, the protrusion 211 can limit the movement limit position of the rack 210, so as to prevent the rack 210 from being separated from the adjusting gear 600.
Referring to fig. 1 to 8, since the locking gear 500 is relatively fixed to the adjusting gear 600 through the gear shaft 610, when the locking gear 500 is engaged to the limiting gear 341, an acting force exists between the locking gear 500 and the annular wall 340, so that the locking gear 500 and the adjusting gear 600 are locked relative to the arc-shaped housing 300, and the headband 200 cannot be tightened and expanded, so that the head-mounted device can be stably worn on the head of the user, the head-mounted device is prevented from being too loose or too tight when the user touches, the head-mounted device can be worn according to the tightness set by the user, the head-mounted device can be suitable for users with head injuries or with the head pressed, and the wearing experience of the user is improved.
When the key 400 is used to drive the locking gear 500 to separate from the annular wall 340, a pressure is applied to the key 400 by the hands of the user, and meanwhile, the headband 200 is pushed and pulled by both hands, so that the relative positions of the two headband 200 can be adjusted according to the head circumference of the user, and the user has a larger operation space, so that the use of the head-mounted device is more convenient. The key 400 uniformly applies pressure to the end surface of the locking gear 500, so that the elastic member 800 can be uniformly compressed, thereby making the deformation of the elastic member 800 relatively uniform and improving the reset accuracy of the locking gear 500.
