The invention provides a head-mounted adjusting device.
In an embodiment of the present invention, as shown in fig. 1, fig. 2, fig. 4, fig. 6 and fig. 7, the head-mounted adjusting apparatus includes:
a mounting case 100;
two racks (not shown) disposed in parallel to the mounting housing 100 and slidably connected to the mounting housing 100;
a gear 200 meshed between the two racks, wherein a limit shaft 210 is convexly arranged on one surface of the gear 200;
the limiting ring 300 is sleeved outside the limiting shaft 210, the outer periphery of the limiting shaft 210 and the inner periphery of the limiting ring 300 limit a limiting ring groove 400, the limiting ring groove 400 comprises at least one limiting section, and the inner periphery of the limiting ring 300 is gradually close to the outer periphery of the limiting shaft 210 at the limiting section;
an annular retainer 500 having an accommodating groove 510 penetrating through an inner annular surface and an outer annular surface, a limiting roller 520 rotatably disposed in the accommodating groove 510, the width of the limiting roller 520 being greater than the width of the accommodating groove 510 in the radial direction of the annular retainer 500, the annular retainer 500 being rotatably disposed in the limiting ring groove 400, and the limiting roller 520 being located at the limiting section; and
a locking switch 600, wherein the locking switch 600 is used for enabling the annular retainer 500 and the limiting ring 300 to rotate relatively, so that the limiting rollers 520 reach the locking position 420 or the free position 410; in the locking position 420, the limiting roller 520 abuts against the limiting ring 300 and the limiting shaft 210 at the same time to lock the gear 200, so that the two racks are fixed relatively; in the free position 410, there is a gap between the limiting roller 520 and the limiting ring 300 or the limiting shaft 210, so that the gear 200 can rotate freely, and the two racks can move relatively.
It can be understood that the head-mounted display device includes a host and a head-mounted adjusting device, one end of each of the two racks is respectively fixedly connected to the host, and the other end of each of the two racks is slidably connected to the mounting housing 100. Without loss of generality, the racks are slidably connected to the mounting case 100 through a rail-sliding groove structure, specifically, two parallel sliding grooves are provided on the case, and the rails are correspondingly provided on the racks, so that the two racks can slide in the sliding grooves. Wear adjusting device accessible and adjust the relative position of two racks to adjust the elasticity of wearing display device, thereby make wear display device and be applicable to different users.
In the invention, the gear 200 is meshed between the two racks, and the two racks can be kept relatively fixed by locking the gear 200, so that the head-mounted display device is kept at a constant tightness; when the gear 200 is released, the two racks can move relatively to adjust the tightness of the head-mounted display device. Specifically, after the gear 200 is released, the two racks can move in the opposite direction or in the opposite direction, and the two racks move in the opposite direction, so that the head-mounted display device can be tightened; two rack looks motions back to back, can transfer loose head-mounted display device.
In the present invention, the gear 200 is locked by locking the stopper shaft 210 since the stopper shaft 210 is protruded from one surface of the gear 200. Specifically, as shown in fig. 7, the limiting shaft 210 is sleeved with a limiting ring 300 at an interval to form a limiting ring groove 400, a limiting section of the limiting ring groove 400 has a locking position 420 and a free position 410, and a limiting roller 520 is rollably disposed in the limiting section. In the limiting section, the inner circumference of the limiting ring 300 is gradually close to the outer circumference of the limiting shaft 210, that is, in the limiting section, the inner circumference of the limiting ring 300 extends in an inward inclined manner in the circumferential direction, so that the groove width of the locking position 420 is smaller than that of the free position 410, therefore, when the limiting roller 520 reaches the locking position 420, the limiting roller 520 can abut against two groove walls of the limiting ring groove 400, that is, the limiting roller 520 can abut against the limiting shaft 210 and the limiting ring 300 at the same time, the rotation of the limiting shaft 210 is limited by the limiting roller 520, and the gear 200 can be locked only by keeping the limiting ring 300 and the limiting roller 520 relatively still with the installation housing 100; when the limiting roller 520 reaches the free position 410, a gap is left between the limiting roller 520 and the limiting shaft 210 or the limiting wheel, and the rotation of the limiting shaft 210 is not limited by the limiting roller 520, that is, the gear 200 can rotate freely.
In the present invention, the locking switch 600 can make the annular holder 500 and the stop ring 300 rotate relatively, and since the stop rollers 520 can be rotatably disposed in the receiving grooves 510 of the annular holder 500, the position of the stop rollers 520 in the stop section can be adjusted by rotating the locking switch 600. Specifically, when the user needs to adjust the tightness of the head-mounted display device, the locking switch 600 may be rotated to adjust the limiting roller 520 to the free position 410, so that the gear 200 may rotate freely, and at this time, the user may directly apply force to the two racks to move the two racks in opposite directions or in opposite directions, so as to adjust the tightness of the head-mounted display device; when the tightness of the head-mounted display device is adjusted in place, the user can rotate the locking switch 600 again to adjust the limiting roller 520 to the locking position 420, so that the gear 200 is locked, at this time, the two racks will remain relatively fixed, and the tightness of the head-mounted display device will also remain constant.
In the prior art, a ratchet wheel is matched with a mounting shell to lock the ratchet wheel, wherein the ratchet wheel and a gear rotate coaxially, and the gear can be locked by locking the ratchet wheel. However, during the adjustment process, the ratchet wheel continuously touches the teeth on the mounting shell, especially when the knob is loosened, the ratchet wheel rotates rapidly, the ratchet wheel continuously collides with the teeth on the mounting shell, and continuous harsh noise is accompanied, so that the use experience of a user is greatly influenced.
In the invention, the head-mounted adjusting device has a locking state and an adjusting state, when the head-mounted adjusting device is in the adjusting state, a user can adjust the tightness of the head-mounted display device by adjusting the relative position of the rack, and when the tightness of the head-mounted display device is adjusted in place, the user can rotate the locking switch to switch the adjusting state to the locking state, and the limiting roller 520 also reaches the locking position 420 from the free position 410, so that the gear 200 can be quickly and reliably locked, and continuous collision cannot occur between the limiting roller 520 and the limiting shaft 210 in the adjusting process, particularly in the locking process, so that the generation of noise is avoided, and the use experience of the user is improved.
Further, in this embodiment, as shown in fig. 3 and 5, the limiting ring 300 is fixedly connected to the mounting housing 100, and the locking switch 600 is configured to drive the annular holder 500 to rotate, so as to realize the relative movement between the annular holder 500 and the limiting ring 300. Without loss of generality, in the embodiment, three mounting convex portions 310 are spaced apart from each other on the outer periphery of the stop collar 300, three stop wheel mounting grooves 120 are correspondingly formed on the mounting housing 100, and the stop collar 300 is fixedly mounted on the mounting housing 100 through the cooperation between the mounting convex portions 310 and the stop wheel mounting grooves 120. Thus, the locking switch 600 drives the annular holder 500 to rotate, the annular holder 500 drives the limiting rollers 520 to rotate, and the limiting rollers 520 move to the locking positions 420 or the free positions 410 to lock the gear 200 or release the gear 200. Of course, in other embodiments, the annular holder 500 may be fixedly connected to the mounting housing 100, the lock switch 600 may drive the limiting ring 300 to rotate, and thus, the limiting segment may also move relative to the limiting roller 520, so as to make the locking position 420 or the free position 410 approach the limiting roller 520, thereby achieving the purpose of locking the gear 200 or releasing the gear 200.
Further, in this embodiment, as shown in fig. 3 and fig. 5, the mounting housing 100 is provided with an abutting part 110, the abutting part 110 is rotatably connected to the mounting housing 100, and the locking switch 600 is drivingly connected to the abutting part 110 to drive the abutting part 110 to move between a first position and a second position; the annular retainer 500 is provided with an extension arm 530, and the pushing part 110 pushes the extension arm 530 to drive the annular retainer 500 to rotate; when the pushing element 110 is located at the first position, the limiting roller 520 is located at the free position 410; when the pushing element 110 is located at the second position, the limiting roller 520 is located at the locking position 420. In this embodiment, the locking switch 600 indirectly drives the annular holder 500, and specifically, the mounting housing 100 is provided with a rotatable pushing member 110, one end of the pushing member 110 is used for driving the locking switch 600 to connect, and the other end is used for pushing the extension arm 530 on the annular holder 500, so that the annular holder 500 can be driven by rotating the locking switch 600 through the pushing member 110. When the pushing member 110 reaches the first position, the annular holder 500 also reaches the corresponding position under the driving of the locking switch 600, so that the limiting roller 520 is located at the free position 410, and at this time, the user can adaptively adjust the tightness of the head-mounted display device; when the pusher 110 reaches the second position, the annular holder 500 also reaches the corresponding position, so that the limiting rollers 520 are located at the locking position 420, and at this time, the tightness of the head-mounted display device can be maintained constant. Of course, in other embodiments, the locking switch 600 may be directly and fixedly connected to the annular holder 500 to directly drive the annular holder 500 to rotate.
Further, in this embodiment, as shown in fig. 3 and fig. 5, a torsion spring 700 is further connected between the pushing member 110 and the mounting housing 100, and the torsion spring 700 is used for pushing the pushing member 110 to the first position. Without loss of generality, in the embodiment, the pushing element 110 moves from the second position to the first position in an anticlockwise manner, and during the movement of the pushing element 110, the torsion spring 700 performs a limiting function to limit the pushing element 110 to move continuously in the anticlockwise manner beyond the first position, so as to prevent the ring-shaped retainer 500 from excessively pressing the limiting rollers 520 at the locking position 420, so that the limiting rollers 520 are blocked in the limiting ring grooves 400 or the structure of the internal component is damaged.
Further, in this embodiment, as shown in fig. 3 and 5, a return spring 800 is further connected between the extension arm 530 and the mounting housing 100, and when the pushing member 110 moves from the first position to the second position, the extension arm 530 compresses the return spring 800; when the pushing element 110 moves from the second position to the first position, the return spring 800 is released to push the extension arm 530, so that the extension arm 530 abuts against the pushing element 110 at the second position. In this embodiment, the urging portion is limited to the first position and the second position by the combined action of the return spring 800 and the torsion spring 700. It can be understood that, in the first position or the second position, the extension arm 530 abuts against the pushing element 110, so the acting force of the return spring 800 can be transmitted to the pushing element 110 through the extension arm 530, and the return spring 800 and the torsion spring 700 respectively generate torques with equal magnitude but opposite directions to the pushing element 110, so that the pushing element 110 can be stably located in the first position or the second position without being affected by an external force. Optionally, an installation boss 531 is disposed on the extension arm 530, a return spring installation groove 140 is disposed on the installation housing 100, and the return spring 800 is sleeved on the installation boss 531 and is accommodated in the return spring installation groove 140, so as to prevent the return spring 800 from generating inelastic deformation during the movement of the extension arm 530 and affecting the function of the return spring 800. Of course, in other embodiments, other limiting structures may be disposed on the mounting housing 100 to directly limit the locking switch 600, that is, to indirectly limit the abutting member at the first position or the second position.
Further, in this embodiment, as shown in fig. 3, fig. 5 and fig. 8, a connecting protrusion 610 is disposed inside the locking switch 600, the pushing member 110 is disposed with a mounting groove 111, and the connecting protrusion 610 is clamped in the mounting groove 111, so that the locking switch 600 can drive the pushing member 110. When the locking switch 600 drives the pushing element 110 to reach the first position or the second position, the head-mounted display device can be correspondingly switched to the adjustment state or the locking state. In this embodiment, the locking switch 600 is fixedly connected to the pushing element 110 by the fitting of the mounting protrusion 310 and the mounting groove 111, and of course, in other embodiments, the pushing element 110 may also be fixedly connected to the locking switch 600 by riveting or screw locking.
Further, in this embodiment, the locking switch 600 is further provided with a first positioning rib 620, the mounting housing 100 is provided with two second positioning ribs 130, the locking switch 600 rotates to enable the first positioning rib 620 to move between the two second positioning ribs 130, and when the pushing member 110 is located at the first position and the second position, the first positioning ribs 620 respectively abut against the different second positioning ribs 130. Thus, when the user rotates the locking switch 600, the first positioning rib 620 abuts against a different second positioning rib 130, and the pushing element 110 is synchronously positioned to the first position or the second position. And when first location muscle 620 butt in different second location muscle 130, the user all can receive the feedback, and can immediately perceive that this head adjusting device has switched to different states to user's use experience has further been promoted. Without loss of generality, in the embodiment, the first positioning rib 620 is disposed on the inner side of the locking switch 600, so that the head-mounted type appearance is more concise and beautiful. Of course, in other embodiments, other positioning structures may be provided on the mounting housing 100 to directly position the pushing element 110.

Of course, in other embodiments, the locking switch 600 and the gear 200 may be connected to the mounting housing 100 by way of annular groove rail fitting, and the locking switch 600 and the gear 200 may also rotate smoothly.
Further, in this embodiment, as shown in fig. 2 and 8, a limit protrusion 631 is disposed on a periphery of one end of the fixed shaft 630, which is away from the locking switch 600, and the limit protrusion 631 abuts against a surface of the gear 200, which is away from the locking switch 600, so as to prevent the gear 200 from being disengaged from the fixed shaft 630, thereby improving connection stability of internal components of the head-mounted adjustment device; further, the fixing shaft 630 has a hollow column structure, and one end of the fixing shaft 630, which is far away from the locking switch 600, is provided with a plurality of through slots 632, so that a deformation margin is left at the end of the fixing shaft 630, and the gear 200 can be conveniently assembled on the fixing shaft 630 from the end.
